Years after, I had the + pleasure of reading John Lions ``Commentary on UNIX'' along with the + source code of UNIX v6. + + Although time has passed, I still feel that the best way to learn how + an operating system works is by reading its code. However, + contemporary UNIX (read Linux, Solaris, etc.) source code is a mess: + hard to follow, complex, full of special cases, plenty of compiler + tricks and plenty of bugs. When Plan 9 source code was released to the + public on its 3rd edition, I knew it was just the material I needed + for my Operating Systems Design course. This commentary is an attempt + to provide a guide to the source code of Plan 9 3rd edition. + + The concepts included are those covered on the ``Operating Systems + Design'' course of 4th year at Universidad Rey Juan Carlos de Madrid + [[153]2]. + + Any reader, specially when following the course, is encouraged to read + the source along with the commentary as well as to modify and enhance + the system. + + Fixed since the first version + + Since the last version of this document, these things have been fixed. + + * Introduction chapter: + + It now says which kernel tree the notes refer to (3rd + edition; june release). + + Figures added for Intel stuff + + Brief description of assembler. + * Starting up chapter. + + Note about why using 9load. + + 9load jumps to tokzero as I was saying, but that does not set + the PC to KZERO. + + fixes in 9load probe routine. + + fixes about the mapping for the Mach structure. + + fixes in ram scanning. + + Small section about PC hardware added. + + Horrendous bug about how do QIDs work fixed (I said that vers + was used to detect removed-and-recreated files, which is not + the case; In fact I think I understood that was not the case + long ago before starting this document. Too sleepy that day? + Too few caffeine? Who knows?). + + pageinit has nothing to do with software for paging, it is + just initializing the page allocator. The starting up chapter + was saying it had to do with software MMU, although on the + next paragraph it was described and the reader could know + what it really does. + + psstate only holds the process state for ps. + + process groups have name spaces, not processes. The + description was confusing. + + Some figures added. + + Note added about the check for pidalloc wrap. + + Note about why to reserve room in the bottom of the kernel + stack. + + Fix about eflags in touser. + + sectioning for functions added. + * Process chapter. + + Notes added about why to use a scheduler stack. + + Note added about why to have two scheduling classes. + + Note added about other synch. means. + + Notes added about asking other processors for things. + + Fix in clockintr. Last lines were for user-level code, not + for non-kernel processes. + + postnote fix. + + noted fix. + + Note for wakeup in pexit. + + procstopwait fix. + + More comments added. + + Fixes in fork. + + note about the lack of incref on slash. + + Some figures added. + + sectioning for functions. + * Files chapter. + + Note added about why to have a limit on file descriptors. + + Non-empty directories can be removed. + + Hint about saveregisters. + + The example for ``..'' now uses walk and not cd, which was + unfortunate because cd does not crosses the mount point. + + Note about why a read from a union must clone the mounted + channels anyway. The comment could be suggesting that the + clone could be avoided, that is not the case. + + fixes in walk. + + Fixes in the pipe device. + + Note about how to avoid the CHDIR trick for exportfs. + + Nested calls to the mount driver are not a problem; msg sizes + are. + + Note about coherence of distributed caches. + + Note about using just pages to do caching. + + Some figures added. + * Memory chapter. + + Note about why to use just physical memory for caching remote + files. + + Note about why the pager avoids waiting for locks. + + Note about the lock+unlock when paging-in. + + Note fix about the use of share while cloning segments. + + Note fix about the check for ESEG while attaching segments. + + Other notes added. + + Figures added. + + Please, if you feel that a figure should be added to clarify + something, that a piece of text should be moved somewhere else to + clarify the exposition, that anything is missing, that anything should + be removed, fixed, etc. just send me a mail to + nemo@gsyc.escet.urjc.es. I will pay attention to it. + + I am grateful to Jean Mehat for the fixes he sent me. Yes, as you can + see, yet another thing to fix is the missing acknowledgements section. + + Introduction + + An OS does mainly two things: it multiplexes the hardware and provides + abstractions built on it. Plan 9 does it for a network of machines. + The nice thing of Plan 9 is that it is centered around a single + abstraction: the file. Almost everything in the system is presented as + files. Therefore, most of the complexity lies on the ``multiplexes the + hardware'' part, and not on the ``provides abstractions'' part. By not + optimizing the system where it is not necessary, even the + ``multiplexes the hardware'' part is kept simple (You should compare + the source code with that of Linux if you don't believe this). + + Before proceeding with the source code, I give you a piece of advice + regarding how to read this document, which shouldn't be read as a + regular book. + + How to read this document + + This commentary is that, a commentary to the Plan 9 kernel source. I + have used the source for the June release of the third edition. It + should be read like any commentary of a program, by keeping both the + commentary and the source side by side. In fact, you should try to + read the system code without reading the commentary. If while you are + reading the code and the commentary, you feel curiosity about what + else is done at a particular file, you should go read it all: remember + that nobody can teach you what you don't want to learn. + + The final goal is to understand the system, how it is built, what + services it provides and how are them provided. As with any program, + it is better to focus on the tasks the system has to carry out. Most + of the commentary will be centered on them. Before understanding the + code of the system, it is wise to take a view to the system as a user. + You are strongly advised to read the manual pages relevant for each + chapter, as well as to use the system either at the Plan 9 laboratory, + at home, or at both. Ask for help if feel you can't install Plan 9 at + home. Once you know the set of services provided, you also know that + has to be implemented, and you will understand the code better. + + While you read the commentary, you will see that I refer to the + authors of the source code as ``the author''. Each time I mention the + author, I am referring to the author(s) of the particular piece of + code discussed. Plan 9 is the joint result of many people. The main + authors of the code are Rob Pike, Dave Presotto, Sean Dorward, Bob + Flandrena, Ken Thompson, Howard Trickey, and Phil Winterbottom. As far + as I know, Rob Pike and Dave Presotto were the system architects; and + Ken Thompson was the architect for the file server. + + Also, whenever I say ``he'' or ``his'', you should understand that I + am saying ``he or she'' and ``his or her''. I do not like typing so + much and for me it is hard to find impersonal sentences where ``he'' + and ``his'' can be avoided. So excuse me, no offense intended. + +Coming up next + + In the next section, I give you some pointers you should follow. They + are mostly research papers about Plan 9. You should read them (well, + at least you are expected to read the first one) to learn more about + the system before looking at its internals. It is good to learn to + follow the documentation pointers ``on demand'', as you feel you need + to know more about a particular topic to understand the code. + + What remains of this chapter is whatever I think is the bare minimum + to understand the source code. Next section gives a quick introduction + to reading code written in C, the language used for the Plan 9 kernel. + You can skip this whole section but take a loot at it when you find + something that is not ``ANSI C'' in the code. The following one is a + quick introduction to PC hardware facilities. + + Remaining chapters describe different topics of the system and can be + read randomly, although it would be good to read chapter [154]2, about + system source code organization, and chapter [155]3, on system + startup, before proceeding with the following ones. Besides describing + how the system boots, chapter [156]3 describes several important + concepts to understand the design of Plan 9. + + To save trees, the source code is not printed on paper. All chapters + refer to code using pointers like /dir/file.c:30,35. They focus on a + given line (or lines). These pointers can be used as ``addresses'' on + the Plan 9 editors you will be using during the course. It is very + convenient to print this commentary, open the acme editor[157]5.1 + full-screen, and then follow the commentary giving the pointers to + acme as they appear. It is even better to use a text version of the + manuscript and open it on acme. Then you can jump to the source by + clicking button 3 on the pointer. What? you don't know how to use + acme? Don't worry, forget this and the next couple of paragraphs and + reread them when you get started with acme. To get started you can + read the paper on acme from volume 2 of the Plan 9 manual [[158]7]. + + If you open the text version on acme, I suggest you execute these + commands by using button 2 on them: +Local bind -a . /sys/src/9/port +Local bind -a . /sys/src/9/pc + + If you used button 2 to execute them, your namespace in acme will have + been arranged so that the files in this directory appear to be also in + the directories with the Plan 9 source code. This way, by using button + 3 on file pointers acme will jump to the given location in a different + window. So, now that your namespace is ready, close this file, go to + /sys/src/9/pc and open this file there. This document will be jumping + to code in other directories (e.g. port); in that case, I suggest you + simply edit the tag of the Acme window for this file to update its + directory (e.g. so that the tag is /sys/src/9/pc/9.txt while reading + files in the pc directory, and it is /sys/src/9/port/9.txt while + reading files in the port directory). Do not Put this file. + + More on acme advice, to get line numbers on a file, select it all by + typing :, and using button 3; then type | awk + '{printf("%-5d\t%s\n",NR,$0)}' (or |cat -n if you are on UNIX), select + it and use button 2. Don't Put the file. To locate identifiers through + the source you can create a script to grep the parameter in *.[ch]. + For your convenience, a copy of the kernel source with line numbers is + installed both at the Linux laboratory and at the Plan 9 laboratory. + + Whenever we refer to a file, a relative path has as the working + directory the directory where we are looking source files on Plan 9. + Absolute path names start always at the Plan 9 root. If you are + browsing on Linux, and Plan 9 is installed at /plan9, that means + /plan9/absolute path name instead. Remember that if you use Linux you + still have wily, an acme look-alike. You have also Inferno, where you + have acme (See the web page for the ``Advanced Operating Systems'' + course [[159]1]). + + I suggest you install Plan 9 on your PC and then use it to read the + source code as I said before. By using the system you will ``feel'' + how it works better, and you will use something that is neither UNIX + nor Windows. There are excellent pieces of advice regarding how to + install Plan 9 in volume 2 of the manual [[160]10]. + + If you feel emotionally attached to Linux, you can at least install + wily, an acme-look-alike for UNIX; but you will be missing something + great. + + When discussing a particular data structure or function, it is good to + see where is it used through the system. To find that, you can use the + grep program. By using it within acme, you can simply click with your + (three button) mouse jump through the occurrences found by grep -n. + + When a particular section of a classical OS textbook would further + discuss a topic being addressed, a pointer of the form [n]/section + will appear, where the ``[n]'' part is a reference to the + bibliography. You do not need to follow this kind pointer immediately, + although that might help you if you feel lost. + + Several times I will be discussing code implementing a system call or + used by a popular command. References such like man(1) instruct you to + read the manual page on ``man'' on section ``1'' of the manual as a + definitive reference on the program or system call discussed. You + should at least browse the manual pages as they are cited; and you can + skip parts that you don't understand there. + + One of the abilities you are expected to learn is that of browsing + through a reasonably sized piece of code or documentation. While doing + that, remember that it is important to ignore at first things we don't + understand and try focus on what you can understand. Of course, unless + you know the not-understood part is not relevant for you, you should + try to understand that part too, and ask for help if you can't. + + NOTE: A chapter describing the disk device driver? at the end? + + NOTE: Convince a colleague to write a companion for the ip + directory? + + Other documentation + + The third edition of Plan 9 comes with a two volume programmer's + manual [[161]9,[162]10]. The first volume, ``the manual'', is the set + of manual pages for the system. Manual pages are packaged into + sections. There are several sections, including a section on commands + and another on system calls and library functions. Manual pages are + similar to that of the ``man'' command on UNIX, although the set of + sections vary. + + The second Plan 9 programmer's manual volume, ``the documents'' is a + set of papers relevant for Plan 9. They discuss one aspect or another + of the system. I expect you to read at the very least several ones, + and I highly recommend you read all of them. You will find that papers + on volume two are not like typical research papers these days, on the + contrary, they are simple, show a new idea or a new way of doing + something, and can be understood by themselves; moreover, they are + implemented. Reading Plan 9 papers is a fine way of get a kind + introduction to the system. + +Manual pages + + The manual [[163]9] is divided in sections. When you refer to a manual + page like man(1), you are referring to the manual page for ``man'' on + section 1 of the manual. Manual pages can be found at several places: + + * Using the man command on Plan 9, like in man 1 man. + * Writing the name of the page (e.g. ``man(1)'') on the acme editor, + and clicking on it with mouse button-2. + * running nroff on Linux for the manual page found at + /sys/man/manX/xxxx. For example, if your Plan 9 tree is at /plan9, + you can: + nroff -man /plan9/sys/man/1/man + On the Linux laboratory, you have also the 9man command that + refers to the manual of Plan 9 installed on the Linux file system; + and ignores Linux manual pages. + * Using your favorite web browser and looking at + http://plan9.bell-labs.com/sys/man + + If, as I recommended, you are using acme to read the source, method 2 + is the most convenient one. + + Now go, read intro(1), and drink some coffee. Give yourself enough + time to assimilate what you read there. + + Done? Ok, if you are really done, you should now know that + + * Section 1 of the manual is for general user commands. You type + them on a shell, or click on their names with button 2 in acme. + * Section 2 is for library functions and system calls. This is the + programatic interface to the system. You are studying how the + system calls described here are implemented. + * Section 3 shows kernel devices, which supply ``kernel files'' you + need to access to use the system. These files show up typically + under /dev. You will be interested mostly on manual pages for + devices we discuss. + * Section 4 has manual pages on file systems that you can mount. + They are supplied usually by user programs that implement some + service. For instance, access to FAT file systems is provided + through a program that services a FAT file system--using the FAT + partition as the storage medium. + * Section 5 shows how you talk to files on Plan 9. Plan 9 is a + distributed system that permits remote access to files. This + section shows the 9P protocol used for that purpose. It is at the + very heart of the system. During the chapter on file systems, you + should be reading this section. + * Section 6 discusses several file formats. For example, the format + of manual pages is shown at man(6). + * Section 7 addresses databases and programs that access them. + * Section 8 is about system administration. Commands needed to + install and maintain the system are found here. Some of them will + appear while reading the code, and you should read their manual + pages. + + Too many things to read? I recommend you read manual pages on demand, + as they are mentioned on the commentary, or as you use the tools + described on them. The very first time you use a new Plan 9 program or + tool, it is good to take a look to its manual page. In that way, as + you use the system, you will be learning what it has to offer. + +Papers + + Documents from the manual [[164]10] can be found at several places + too. You can use page on Plan 9 (or gv on Linux) with postscript files + in the Plan 9 directory /sys/doc. You can also use your favorite web + browser and look at http://plan9.bell-labs.com/sys/doc. These are the + papers: + + Plan 9 From Bell Labs + is an introductory paper. It gives you an overview of the + system. Reading it you will find that Plan 9 is not UNIX and + also that networks are central to the design of Plan 9. + + You are expected to read this one soon. + + The Use of Name Spaces in Plan 9 + gives you more insight into one key feature of Plan 9: every + process has its own name space. You can think that every + process has a ``UNIX mount table'' for itself; although that is + not the whole truth. + + You are expected to read this one. + + Getting Started with Plan 9 + is an introductory document with information you need to know + to start running Plan 9. + + The Organization of Networks in Plan 9 + shows how networking works on Plan 9. The section on Streams is + no longer relevant (Streams are gone on 3rd edition), although + it is worth reading it because the spirit remains the same. + + How to Use the Plan 9 C Compiler + will be helpful for you to do your assignments. Once you know + how to use C, this paper tells you how to do it on Plan 9. More + on this on the next section. + + Maintaining Files on Plan 9 with Mk + describes a tool similar to make. It is used to build programs + (and documents) on Plan 9. This paper will be also of help for + doing your assignments; as you are expected to use both C and + mk. More on this on the next section. + + The conventions for using mk in Plan 9 + is also good to read. It shows how mk is used to build the + system. This paper can save you some time. + + Acid: A Debugger Built From A Language + is an introduction to the debugger. You will find that it is + not similar to the kind of debuggers you have been using, and + it is highly instructive to debug using Acid. + + Acid Manual + is the reference manual for the debugger. + + Rc The Plan 9 Shell + shows you the shell you will be using. If you have used a UNIX + shell that is probably all you need. You can learn more of rc + as you use it. Remember that rc is installed also on Linux. + + The Text Editor sam + describes the editor used on Plan 9. It is a fine editor + although you can go with acme instead. Indeed, I heavily + suggest you start by using Acme. Of course, it is healthy to + try sam too. The sam editor is installed on Linux too. + + Acme: A User Interface for Programmers + describes the Acme editor. Well, as the title says, it is more + like an environment. You have a clone for Linux called wily. I + used Emacs for years until I found acme, and the same may + happen to you. You should read this document and play with acme + or wily, to navigate the source code. By the way, it is named + ``acme'' because it does everything. + + Installing the Plan 9 Distribution + is something to print and keep side by side with the keyboard + if you intend to run Plan 9. The title says it all. + + Lexical File Names in Plan 9 or Getting Dot-Dot Right + describes how file name resolution works despite the existence + of the bind(2) system call. Read this before you read the + chapter on Plan 9 files. + + There are several other papers, good to read too, that I have omitted + here for the sake of brevity. + + I recommend you fork now another process in your brain and read all of + them in background. Whenever I feel its better for you to read first + any of them, I will let you know. + + Introduction to Plan 9 + + This section intentionally left blank[165]5.2 + + Source code + + Plan 9 is written in assembly (only a few parts) and C. You must read + C code to understand how the system works. Moreover, you are expected + to write your own C code to modify the kernel in your assignments. + + This section will introduce you to C to let you read it. Nevertheless, + you should read the following two books if you have not done so: + + The C programming Language, 2nd ed. + is a good, kind, introduction to the language [[166]5]. It is + easy to read and it pays to do so. The compiler used on the + book is the UNIX C compiler. You can find how to use the Plan 9 + C compiler on the paper ``How to use the Plan 9 C compiler'' + [[167]8]--these guys use descriptive titles, don't do them? + + The practice of programming + is a ``must read'' [[168]4]. It will teach you those things you + should have been taught during the programming courses. + + Now that you have pointers, I will first comment a bit of Plan 9 C, + then a bit of how to use mk to avoid the need to manually call the C + compiler. + +Notes on C + + I include this section on C mostly to document a few differences with + respect to ANSI C, and for the sake of completeness. But I really + recommend you to read The C programming Language [[169]5] if you don't + know C yet. + + Where is the kernel C code? + + The system source code is structured as a set of directories contained + on /sys/src/9. Although there are valuable include files at + /386/include (and similar directories for other architectures) and + /sys/include. You will be using mostly these directories: + + /sys/src/9/pc + contains machine dependent code for PC computers. This code + assumes that you are running on a PC. + + /sys/src/9/port + contains portable code. This code is shared among different + architectures. + + /sys/src/9/boot + contains code used to bring up the system. + + Other directories under /sys/src/9 contain source for other + architectures, but for the ip directory--which contains a TCP/IP + protocol stack. For Plan 9 file systems, the kernel source code is + found at /sys/src/fs instead. Subdirectories of fs/ follow the same + conventions that subdirectories of 9/. I do not comment the file + system kernel, it is a specialized kernel (borrowing a lot from the + generic kernel) designed to serve files fast. + + C and its preprocessor + + If you take a look to any of those directories, you will find files + named ``xxx.c'', ``xxx.h'', and ``sss.s''. Files terminated on ``.s'' + are assembly language files. They contain low-level glue code and are + used where either C is not low-level enough to let the programmer do + the job, or where it is more natural to use assembler than it is to + use C. Files named ``xxx.c'' and ``xxx.h'' are the subject of this + section: they contain C source code. + + The C language has a compiler proper, and a preprocessor. Files are + first fed to the preprocessor, which does some work, and the result is + finally sent to the compiler. The compiler generates assembly code + that will be translated to binary and linked into an executable file. + On Plan 9, the compiler is usually in charge of preprocessing the + source too, so a single program is run on the source; nevertheless, + you better think that source is first fed into the preprocessor and + the result goes automatically to the compiler proper. + + C source files can be thought as ``implementation modules'' or package + bodies. H source files can be thought as ``definition modules'' or + package specs. When someone writes a C module to be used on a program, + the module has a header file (a ``.h'' file) with declarations needed + to interface to the module and a C file (a ``.C'' file) with the + implementation. + + Consider these three files: +/* this is main.c */ /* this is msg.h */ /* this is msg.c */ +#include "msg.h" typedef char *Msg; #include "msg.h" +main() void set(Msg *m,char*s); +{ char *get(Msg m); void set(Msg*m,char*s){ + Msg m; *m=strdup(s); + set(&m,"Hi world!"); } + char*get(Msg m){ + print(get(m)); return m; +} } + + The point to get here, is that msg.h has the interface to msg.c. It + contains a type definition for Msg and the header of a couple of + functions. The main program (always called main in C) can include + these definitions and then use them. Files ``main.c'' and ``msg.c'' + can be compiled separately into object files and then linked together. + + When compiling main.c, the preprocessor will notice the #include + directive and replace it by the set of lines found in the named file + (msg.h in the example). It is textual substitution. The preprocessor + knows nothing about C. The resulting (preprocessed) file would be sent + to the C compiler proper. In the example, some includes must be + missing since there is no prototype for the print function (and the + same happens with strdup). + + Another useful preprocessor directive is #define, which lets you + define symbols. Note that again, this is textual substitution--the + preprocessor knows nothing about C. + +#define SPANISH 0 +#define ENGLISH 1 +extern int lang; +void hi() { + if (lang == SPANISH) + print("hola"); + else print("hello"); +} + + After the #define lines, the preprocessor will replace any ``SPANISH'' + text with ``0'' and ``ENGLISH'' with ``1''. The compiler will see none + of these symbols. + + Functions + + C has no procedures: every subroutine is a function. The result of a + function may be ignored though. Look at this function: + +int add(int c, int l) +{ + return c+l; +} + + It receives two integer parameters named ``c'' and ``l''--parameters + are always passed by value on C. It returns an integer value (the + first ``int'' before the function name). The ``return'' statement + builds the return value for the function and transfers control back to + the caller routine. + + A function can return ``void'' (which means ``nothing'') is provided + to let a function return nothing. There is another use of void, a + pointer to void is actually a pointer to anything. + + When a parameter passed to a function is not used, you can declare it + without a name, as in +int add3(int c, int) +{ + return c+3; +} + + This is not allowed by ANSI C. In this example, of course, it is silly + to declare a parameter and not to use it. However, when a function + should present a generic interface, and a concrete implementation of + the function does not need a particular parameter, it is wise to leave + the interface untouched and not to use the parameter. + + For instance, imagine that to open a file you should use a function + with this prototype: + + int open(char *name, int just_for_read); + + Now imagine a particular file on a CDROM is opened. In the + implementation, it is not necessary to specify the open mode because + it has to be ``read-only''. Now look at this function: + + int open_cdrom_file(char *name, int) + { ... + } + + It implements the above interface, and has an unused parameter. + + To use a function it suffices to know its header. We can know it + because we #included a file where the header is kept, or because we + are calling the function after its implementation. + + Of course, functions can be (mutually) recursive. + + Data types + + There are several primitive data types: char for characters, int for + integers, long for long integers, long long for longer integers, + double for real numbers. These are signed, and you have types defined + with a leading ``u'' for the unsigned versions (e.g.: ulong, which is + actually unsigned long). + + Arithmetic operators are as usual, with the addition of ++ and - which + increment and decrement the operand. They may be used either prefix or + postfix. When prefix, the argument is incremented (or decremented) + prior to its use in the expression; when postfix, the argument is + modified after used for the expression. For instance, i++=j++ means: +i=j; +i++; +j++; + + whereas ++i=++j means +i++; +j++; +i=j; + + The modulus operator is ``%''. Assignment is done with =. Assignment + is sometimes ``folded'' with another operator. For instance, i%=3 + means i=i%3, x|=0x4 means x=x|4, which does a bitwise OR with for. `&' + is the bitwise AND operator. The operator ``x'' negates each bit in x, + so x=x inverts every bit in x. + + Booleans and conditions + + There is no boolean in C, any non-zero integer value (or convertible + to integer) is understood as ``TRUE''. Zero, means false. + + Relational operators are ==, !=, <=, >=, <, >, where != means ``not + equal''. You can use ! to negate a boolean expression. More complex + boolean expressions can be built using && (and), || (or) and ! (not). + Once the compiler knows that a boolean expression will be true (or + false) it will not evaluate the rest of the expression. Some would say + that C has shortcut evaluation of boolean expressions. For those of + you how know Ada, in C you are always using ``and then'' and ``or + then''. For instance: on 1 || f(), function f would never be called. + The same would happen to 0 && f(). This is very useful because you can + check at a pointer is not nil and dereference it within the same + condition. + + As Plan 9 is meant to run anywhere in the world, it has to cope with + every language. A Rune data type is defined (it is actually an + unsigned short) to support strings of ``characters'' in any language. + Rune is used to represent a character or a symbol, hence the name + (some languages use symbols for words, or lexems). Remember that char + has only 256 values which are not enough to accommodate symbols on all + languages. The character encoding system is called Unicode, encoded + using UTF-8. UTF-8 is compatible with the first 128 ASCII characters, + but beware that it will use several bytes when needed. And beware too + that it is not compatible with ISO.8859.1 that you use on Linux. + + Given primitive types, you can build more complex types as follows. + + pointers + A pointer to a given type is declared using *; e.g. char *p is + a pointer to character. You refer to the pointed-to value by + using also *, like in *p--which is the character pointed by p. + + The operator & gives the address of a variable; hence, given + int i, the declaration int *p=&i would declare a pointer p and + initialize it to point to i. A function name can be used as a + pointer to the function, like in + +int (*f)(int a, int b) = add3; /* the previous add3 function */ +... +g=(*f)(1,2); + + arrays + An array in C is simply a pointer with some storage associated, + do not forget this. For instance, char s[3] declares an array + named s of three char slots. The slots are s[0], s[1], and + s[2]. Array indexes go from zero to the array length minus one. + + Arrays can be initialized as in + +int arry[3] = { 10, 20, 30 }; + +int tokens[256] = { + ['$'] DOLLAR, + ['/'] SLASH +}; + + The last example is an array of 256 integers. We plan to index + it using a character (which is a small integer in C). And we + only initialize slots corresponding to characters '$' and '/'. + This initialization style is an addition to ANSI C in Plan 9, + and it is very useful: instead of using conditionals to check + for dollars and slashes and generate a number, we can spend a + few extra bytes and allocate one array holding an entry for + every character; for those of interest, we place there the + values desired; for others, we don't care. + + Because arrays are actually pointers with some storage, C has + pointer arithmetic. Assume this + +int a[3]; +int *p=a; + + Here, p points to a[0]. Well, p+1 is a pointer pointing to + a[1], p-1 would point to the integer right before a[0]. + + Also, if p points to a[1] and q points to a[0], then p-q would + be 1: the number of elements between the two pointers. + + As you can imagine, these to expressions are equivalent: a[i] + and *(a+i). + + Beware, p=a will copy pointers, not array contents. Use memmove + to do that. + + structures + An struct is the equivalent of a record in Pascal. It is + declared by giving a set of field declarations. E.g.: + +typedef struct Point Point; +struct Point { + int x; + int y; +}; + +Point p = (Point){3,2}; +Point q = (Point){ .x 3, .y 2 }; + + declares a new struct tag, Point; declares a point p of type + Point; initializes it with a copy of the Point {3,2}. + ``Literals'' of structures are called ``structure displays'' in + Plan 9's C. They are an extension to ANSI C. + + In the example above, struct Point {...} declares the structure + with an structure tag Point, so that you can say struct Point + p. But it is customary to give a synonymous for the new type + ``struct Point'' by using typedef. Typedef defines a new name + (the Point on the right in the example) for an existing type + (struct Point in the example). + + Once p has been declared, p.x and p.y are names for the members + (i.e. fields) of the p structure. + + Structures can be nested like in: + +struct Line { + Point origin; + Point end; +}; + + And we would say l.origin.x, provided that l is a Line. + + If a struct, member of another struct, has no name its members + are ``promoted'' to the outer struct. That is to save some + typing. For example: + +typedef struct Circle Circle; +struct Circle { + Point; /* has no name! */ + int radius; +}; +Circle c; + + And we could say things like c.x, c.y, and c.radius. Both x and + y come from Point! You can even say c.Point, although it would + be tasteless on this case. Member promotion and unnamed fields + are an extension to ANSI C. + + When you have a pointer to an structure, you can refer to + members of the structure in several ways: + +/* The way that you should know by now: */ +Point *p; +(*p).x =3; + +/* A more convenient way */ +p->x = 3; + + Everybody uses the -> form, and nobody uses the (*x).y form. + + Unions + A union is a struct where only one of its fields will be used + at a time. It is used to build variant records, although it is + a bit more flexible. For instance: + +typedef struct Vehicle Vehicle; +struct Vehicle { +#define CAR 0 +#define SHIP 1 + int kind; + union { + int number_of_wheels; + char can_go_underwater; + }; +}; + + Note how we used an anonymous union (one with no name) within + Vehicle. We can use either one field or another of the union: + they will be sharing storage. We cannot use both at the same + time. + + More examples: +/* array of 4 points; to use like in: arry[3].x, arry[2].y, etc. */ +Point arry[4]; +/* A polygon that contains the number of points, and an array with them. */ +struct Polygon { + int npoints; + Point points[MAXPOINTS]; +}; + + Control structures + + Control structures are very easy to learn. All of them use sentences + as their building blocks. Sentences are always terminated by + semicolons. Several sentences may be grouped to form a block using { + and }. At the beginning of a block, you may declare some variables. + + while + To repeat while the condition holds: + + while(*p){ + *q++ = *p++; + } + + A variant tests the condition at the end and iterates at least + once: + + do { + x[i]++; + x[j]--; + } while(i != j); + + for + is a generic iteration tool. + + for (i=0; ipdb) are updated for the upper memory. The range for video + memory is set write-through (you don't want the cache to retain + just written pixel values). The range used by ROMs and devices + you want to be uncached, to interact with the devices directly. + The routine mmuwalk returns a page table entry (pte) given the + virtual address. Remember that below 4M physical addresses were + mapped one-to-one at KZERO? KADDR remembers: The author knows + it cannot use physical addresses, because the kernel is also + running with paging enabled (i.e. using virtual addresses). A + physical address is converted to a kernel virtual address by + using KADDR (i.e. by adding KZERO). That is because for kernel + usage, physical memory is mapped at virtual addresses starting + at KZERO. Although right now not all physical memory is mapped + at KZERO, that is going to change soon. + The page table being updated it the one for the boot processor, + it will be used later as a template to setup new page tables. + memory.c:429 + Every protection change on the page table requires a TLB flush. + Otherwise, until the next context switch, entries within the + TLB would retain the old protection flags. You will see + mmuflushtlb in the virtual memory chapter. + memory.c:431,432 + These two routines scan available memory and fill up Rmaps + accordingly. The author probably wrote two routines because + unlike regular RAM, upper memory must take into account video + memory and the like. These routines update the page table for + the kernel to make KZERO be the starting of a map for all + physical memory. Bby now, KADDR can be used only for physical + addresses within the map at KZERO, which are just 4M. Starting + to fix that now. + memory.c:440,452 + conf is updated to keep the address (base) and number of pages + (npage) of the first RAM map; it is also updated to keep the + address and number of pages of the biggest map. Hopefully, on + the PC, the first map would be conventional memory, and the + second one will contain all extended memory. + + But, how do umbscan and ramscan work? + + Filling up allocators + + main... + meminit + umbscan() Scans for UMB blocks. + + memory.c:208,253 + umbscan starts looking past the end of video memory up to the + ROM signature at 0xc0000. It does not go up to 0xf0000 because + a two-byte check at 0xc0000 can tell us if there is a ROM + mapped there by the hardware or not. + memory.c:228,229 + At each pass, it writes the first and last byte of every 2K + chunk with 0xcc. + memory.c:230,233 + If reading back those bytes does not yield the just written + value, it is not real RAM. It must be a ROM then. So rewrite + p[0] and p[1] just to be sure that if they were on registers + (as dictated by the compiler), their values are in sync with + the real value in memory. Not sure why they write p[2], but + could be for a similar reason. p[2] seems to contain the number + of 512 byte blocks at the ROM scanned. + memory.c:234 + If the two bytes starting the 2K block match the values just + written (the signature of a ROM), skip the number of 512 byte + blocks recorded by the ROM in the third byte. This portion is + not kept in the allocator. + memory.c:238,239 + If the two bytes are 0xff, make the memory available for + read-only allocation by calling mapfree (Note the rmapumb map + and not the rmapumbrw map). Remember that it is not regular RAM + because the read value was not what the routine wrote. But + blocks marked with 0xff seem to hold device RO memory for us to + read. + memory.c:241,242 + It was regular ram, so make it available for allocation. + Adjacent maps will be coalesced. + memory.c:246,252 + Finally, looks like if the first two bytes at 0xe0000 are 0xff, + not signed by a ROM, and not regular RAM, indicate that there + is device memory (64K) for us to read. Place the memory in + rmapumb. + + main... + meminit + ramscan() Scans for regular RAM blocks and updates the page table. + + memory.c:256 + umbscan was easy, tricky because of PC messy memory management + for IO devices, but easy. Now, ramscan has the important task + of updating the the kernel page table to reflect the installed + ram. Besides, it fills the ram map as memory gets scanned. + memory.c:274,276 + The routine leaves untouched the range from 0 up to 0x5fff. If + you look at mem.h:33,39 you will see some stuff, going from the + interrupt descriptor table, and information from 9load up to + the Mach structure for this processor at 0x5000 (see + figure [180]3.2). Therefore, start by putting into the rmapram + allocator memory going after the Mach structure up to the end + of conventional memory (640K). To determine the end, it reads + BIOS information at 0x400--again, a very low address better + left untouched. + memory.c:278,280 + From 640 up to 1M we had the UMBs scanned before, and from 1M + on we had the kernel loaded. (Looking that the mkfile you see + how the image is linked to start at kernel virtual address + 0x80100020 which leads to 0x00100020 physical address). So, + only memory from the end of the kernel upwards may be used now. + The author gives to the allocator the memory starting at the + end of the kernel. The linker places the symbol end at the very + end of the kernel image, past the data and bss segments (note + that our stack ``segment'' is actually a bunch of bytes after + our Mach). How much memory do you have? By now, the author + places in the allocator at least MemMinMB MBytes. That has to + be a reasonable low value. By allocating at least that, the + author can use the allocator in the following code that scans + for more available memory. + memory.c:290,301 + If no hint was given about how much memory is installed, it + makes a guess by reading from CMOS the configured value. In any + case, pretend to have at least 24 MBytes. The PC is not so good + at letting the system know how much memory is installed, there + are many variants out there. Most of the complexity of umbscan + and ramscan has to do with the idiosyncratic nature of the PC. + memory.c:309,314 + Starting at the page after end+MemMaxMB, it is going to check + one MByte at a time if the memory is there or not. The trick is + to write a silly value (line :312) at the first word of the + Mbyte being tested, and see if we can read it back. If the + write did work, there is memory. The author is saving the value + actually stored at address KZERO, can you guess why? + memory.c:320,321 + While it scans for memory, a page table reflecting the actual + memory installed is built. So, the physical address scanned is + converted to a kernel virtual address, and used to index into + the first level page table. table points to the entry in the + first level page table (page directory, or PD) corresponding to + the virtual address scanned. Now going to update the ``image'' + of physical memory mapped at address KZERO to reflect the + memory actually installed. + memory.c:322,328 + If the entry is null, there is no secondary page table, and it + must be allocated. In line :326 the entry in the PD is updated + to be valid and point to the secondary page table (PT) just + allocated. By zeroing it, the routine invalidates all its + entries--valid bit is zero. Line :327 is reseting a counter + that we will discuss below. Saw how it can allocate memory + while filling up the allocator? It was convenient to place a + few Mbytes there at line :280. + memory.c:329,330 + Now getting a pointer to the secondary page table entry for the + virtual address scanned. The macro PPN gives the physical page + number (a physical address, actually). + When the author gets a pointer he pretends to use, it must be a + kernel virtual address (i.e. bigger than KZERO). However, page + tables keep physical addresses. Do you get the picture? + memory.c:332,332 + Establish the mapping by setting the physical page address, the + valid bit, and write permission. The flush must be done too, + remember why? + Since the PTEUSER bit is not set in the entry, only the kernel + (ring 0) can access this virtual memory page. + memory.c:344,372 + Here is the actual scan for memory. The commentary is a ``must + read''. mapfree is used to place memory under the allocator; + its parameter is one of rmapumb (UMB memory), rmapram (Real + memory for use), and rmapupa (Memory that seems not to be + there). For regular RAM, enable write permission for the MMU; + for UMBs (i.e. device memory), set it uncached to get straight + to the device memory; and for ``phantom'' RAM, clear the map. + The *pte++=...is used to update the mapping and advance the + pointer to the next page table entry. Each of the three if arms + map a whole Mbyte at a time once the check for the first word + of the Mbyte tells us the kind of memory there. To know why one + MByte at a time, ask yourself whether you can install on your + PC less than a MByte of extra memory. Another thing to note is + that the author is counting in nvalid how many pages are + available. The counters are reset at the beginning of a 4MByte + block, i.e. at the beginning of a page mapped with the first + entry of a secondary page table. + memory.c:383,393 + And here is why. On the PC, a first level page table entry can + be used to map a whole bunch of 4MBytes (called a + ``super-page''), without using any second level page table. If + the page address starts at a 4Mbyte boundary, and the pages on + the 4Mbyte block just scanned are of one kind, the entry in the + first level page table (*table) can be used to map the 4Mbyte + block. nvalid knows how many pages there are of each kind. + memory.c:392 + When the ``super-page'' map is not used, the pointer to the + secondary page table at map is cleared. Next time it is checked + at line :323, a new (secondary) page table is allocated for the + next 4Mbyte chunk. If a super-page map was used, the pointer is + not released and the memory used by the old secondary page + table (now unused) will be reused for the next non-existing but + needed second level page table. + memory.c:398,399 + Perhaps the routine used a ``super-page'' and saved an + allocated second-level page table that now is unnecessary. + memory.c:340,401 + And perhaps maxmem is not page-aligned. Place the remaining + part of maxmem within the not-existing memory allocator. + memory.c:402,403 + In any case, ensure that from maxmem to the end of the memory + range the ``memory'' is registered as not backed up. Imagine + that later someone plugs in a PCMCIA memory card, memory will + be moved (allocated) from rmapupa to (deallocated) xrmapupa. + Now the kernel can ask for memory at xrmapupa and use it. + memory.c:406 + Finally, restore the word at KZERO messed up previously for + memory checking purposes. Kernel allocators are filled up + reflecting the actual memory installed in the system, and the + mapping starting at KZERO has entries appropriate for the whole + physical memory. + + Dynamic kernel memory + + As we saw, the RAM map allocator is not enough to provide dynamic + kernel memory. It was good at registering (un)allocated contiguous + portions of memory areas in the system, but it is good just for big + chunks of memory. Also, it is not to allocate and free repeated times + a given portion of memory because it would not tolerate + fragmentation--remember that it may even drop the last fragment? + + The map is used during boot to allocate UMB areas for devices, and to + collect available RAM for dynamic memory allocation. It is xalloc that + collects that RAM for later use by the dynamic memory allocator. + main.c:142 + the call to xinit initializes the allocator. + + main + xinit() Initializes xalloc with blocks from the Rmaps and tells + palloc. + + /sys/src/9/port/xalloc.c:45,84 + It initializes a list of ``holes'' (i.e. memory to allocate) + given the information in conf. It uses the first and the + biggest chunk of RAM, as recorded in npage0/base0 and + npage1/base1. Perhaps it would have been better to turn Rmaps + into the interface between the machine dependent and the + portable part; the PC part could fill it up, and xalloc could + collect those RAM maps found in the appropriate rmap. Probably + the author's reason not to do so is that some other + architecture may not need resource maps at all and its + implementation (conf memory banks) is admittedly more simple. + Although the collected memory should be enough, xalloc could + run out of memory, yet have more memory available in + rmaps--despite the recombination of fragments done by rmapfree + will make its best to end up with a big map holding most of the + installed memory. In any case, you better avoid dynamic memory + if you can allocate an array of structures and keep on using + it. Memory fragmentation is not to be underestimated. + xalloc.c:57,66 + Pages (page frames) are removed from the bank 1 in conf and + added with xhole to the allocator. palloc.p1 is initialized + with the starting address for the pages removed; this is not + relevant for us now, but palloc is the source for page (frame) + allocation in the system, and fields p0, np0, p1 and np1 are + used for that. As it happens in conf, the author maintains + information about just two memory banks. + At most conf.upages are placed in xalloc. Those pages are to be + used for user stuff. + xalloc.c:68,75 + Pages are removed from the bank 0 in conf and added with xhole + to the allocator. palloc.p0 is initialized too. + xalloc.c:77,78 + The number of pages placed under allocation is recorded in + palloc's np0 and np1. + xalloc.c:79,82 + Until now, conf recorded physical addresses for banks 0 and 1 + (xhole receives physical addresses, as rmaps do). But from now + on, conf records kernel virtual addresses for both banks. One + point here is that from now on npage0/npage1 do not keep the + number of pages in each bank, but the uppermost bound for each + back; perhaps this is a bit confusing. + + Try to understand yourself how other xalloc routines work. Take a look + first to the data structures near the top of the file. While reading + them, note how ilock is used to prevent race conditions--you will + learn why in the process chapter. I suggest you start by reading + xalloc (xallocz, actually), thenxfree, finally the other ones. + + There are 128 (i.e. Nhole) memory pools. Are they enough to use xalloc + as a generic allocator? No. xalloc should be used just for big, + long-lived, kernel data structures. + ../../libc/port/pool.c + For actual dynamic memory the kernel uses pools. pool.c + implements generic memory pools where memory can be allocated + and deallocated. By using different pools for different + purposes, fragmentation can be fought. Pools are like + ``arenas'' in some programming languages. In fact, pool.c is in + libc/ and is used by user programs as the C library dynamic + memory provider. Pools are appropriate for allocation of even + small and short-lived data structures. Fragmentation would be + contained within the pool. + /sys/src/9/port/alloc.c + As the pool interface is generic, hence more complex than it + ought to be, a regular malloc interface is built on top of the + pool interface, in alloc.c. malloc is very much like poolalloc, + but allocates memory from a 4MBytes pool. There are a few + differences regarding the C library malloc interface. + alloc.c:21,36 + A pool is declared for malloc. Note the generic programming + again. Routines are placed into the pool to allocate more + memory for the pool, merge, lock, unlock, print, and panic on + the pool. xalloc is used as the allocation routine. You already + saw a bit of generic programming before, when the routines to + process plan9.ini worked independently of how to read and seek + on particular devices. The trick was to use pointers to + functions and stick to a well defined interface. The code + called read and seek using the interface (the function + prototype) without knowing what was the actual function used. + As pools are generic, they use routines noted in lock and + unlock fields to allow concurrent usage of the pool. For + malloc, the routines end up using ilock on a Private.lk field. + This contortion is needed because it is malloc who knows how to + lock things in the kernel, yet pools must be able to acquire + locks. + + smalloc() Allocates zeroed dynamic memory (must succeed). + + alloc.c:172,177 + A smalloc routine is included to request dynamic kernel memory + when the allocation must succeed. When there is not enough + memory, it makes the caller sleep for a while and tries again; + and so on until it gets the memory. There are several places in + the kernel where the author prefers to wait for memory instead + of reporting a ``not enough memory'' error; smalloc is used + there instead of malloc. smalloc zeroes the memory allocated. + + malloc() Allocates zeroed dynamic memory. + + alloc.c:186,199 + malloc is like malloc, but it zeroes the memory allocated. That + is both for security issues and to be sure that anything + allocated there gets a reasonable initial value: nil pointers, + zero counters, etc. Shouldn't malloc just call mallocz? + In all these routines, setmalloctag is used to record the PC + that called the allocation routine. That is to find out who is + guilty for bad usage of memory allocation routines; and also to + know who is using a given portion of memory. All in all, for + debug purposes. + Apart from these details, the code should be easy to + understand. While reading the file, ignore the pimagmem pool, + used for program Images but not related to the malloc + interface. It seems to be declared in alloc.c to reuse the + locking and debugging routines that operate on pools near the + beginning of the file. By making them receive a Pool and not + use directly the mainmem one, they can be applied to pimagmem + too. Shouldn't these generic routines be moved to pool.c? + + So, regular dynamic kernel memory (i.e. malloced one) comes from + malloc (or smalloc, or ...) in alloc.c, which in turn uses a pool + (initially 4MByte) supplied by pool.c, confining fragmentation to be + inside the pool. Several pools are used for different things (malloc + and Images, by now). Pools are fed from RAM maps corresponding to + installed memory. The lowest level is necessary to discriminate RAM of + different kinds, the next one to reduce fragmentation, and the upper + one as a convenient interface. + + Architecture initialization + + main.c:141 + archinit sets up a generic interface to operate on this + particular architecture model. Yes, it is a PC, but there are + very different kinds of PC. + dat.h:216,229 + This is the interface to highly architecture dependent + routines, they vary from one PC model to another or they must + be performed only at particular PC models--this is very useful + to make the code work for both multiprocessor PCs and regular + PCs. + + main + archinit() Initializes architecture specific procedures. + + devarch.c:535,542 + The way to select concrete implementations is to scan a table + of known architecture models and set the global arch pointing + to the right entry. A generic entry is used if the exact model + is unknown. + devarch.c:544,556 + Conventions are used to make more simple the table of + knownarchs. If any routine is not specified by the selected + entry in knownarchs, it is defined as the generic routine. + Looks like, in Object-Oriented words, knownarchs is redefining + routines for concrete archs and inheriting everything else from + the generic one. Simple yet effective. + devarch.c:560,563 + Pentiums and above have a Time Stamp Counter (tsc) builtin that + counts the number of cycles gone in the processor. It is better + to perform time measures than the external programmable clock. + If you know the Hertz the machine is running at, you know the + exact time since the last time you reset the tsc counter. + Forget everything else in archinit by now. + +Traps and interrupts + + Traps are important because system calls, page faults, and other traps + (exceptions) are used to request some service from the kernel (perform + a system call, repair a page fault, etc.). The intel has several + protection rings. Plan 9 uses 0 for kernel and 3 for users. Each ring + has its own stack. The stack used for ring 0 is the kernel stack. When + the hardware detects a trap, it saves the processor context in the + kernel stack. After that, what happens depends on the entry for the + given trap number in a table called IDT (interrupt descriptor table). + That table contains ``pointers'' to routines that handle the trap. As + the Intel has segmentation, each entry contains a small number to + describe on which segment the routine resides. The small number is + used as an index into a Global Descriptor Table (or GDT) that contains + descriptors for segments in the system (base address, length, + protection). The whole picture was seen at figure [181]1.2. You + already knew this, right? + + Remember that code segments determine the protection ring you are + running at. There are different text and data segments (as well as + other extra segments courtesy of Intel) for users (ring 3) and kernel + (ring 0). Other than protection, hardware segments are used almost for + nothing else in Plan 9. The paging hardware is all the kernel needs. + + By the way, you know which one is your current kernel stack, but + beware that it would be a different one as soon as you get real + processes running and such processes issue system calls. Each process + has its own kernel stack used by the kernel to service its traps. + + I won't say more about how the Intel hardware deals with traps and + interrupt as I feel this is enough to understand the code. + + main.c:143 + trapinit is called to initialize trap handling. + + main + trapinit() Initializes interrupt and trap vectors. + + trap.c:142,163 + trapinit fills up the IDT with entries for the 256 trap + numbers. Each entry in the IDT has several fields. Fields d0 + and d1 hold the address for the handling routine. Plan 9 keeps + in vectortable the routines handling traps and interrupts. + Lines :145, :160, and :161 store the routine address (vaddr) + using the two fields d0 and d1. Ask Intel why you must use two + fields to store one address. The KESEL at line :161 is + specifying that the routine address refers to the kernel + executable code segment; i.e. the processor will jump to ring 0 + and execute the routine in kernel mode. See figure [182]1.2. + trap.c:145 + For all traps, set the ``present'' bit in the entry (SEGP). + That tells the hardware that the entry is valid. + trap.c:148,154 + Why not fold these two branches? For breakpoints and system + calls the entry is set up as an ``interrupt gate'' at privilege + level 3, that is, user code is allowed to issue an int + instruction to perform a system call or to notify a breakpoint. + trap.c:156,159 + For any other kind of trap, the privilege level is set to 0 + (kernel). That means that those traps should not be ``called''. + Well, the page fault trap and others are among them. And they + should not be called. It is just that the hardware can generate + them, but users cannot use an int instruction to request such + traps. If users try to do so, they will get a protection + fault--which is yet another trap generated by the hardware. + trap.c:162 + Use the next entry in the vector table for the next trap. The + pointer is incremented in 6 characters each time, not in 4. + Why? + l.s:549,805 + In l.s you see that the vector table does not contain pointers + to handlers, but instead, it contains binary code to call the + handler (the byte after the call is a parameter specifying the + trap number). The code calls strayintr (or strayintrx) in l.s. + These are the interrupt handling procedures pointed to by IDT + entries. By using the table, trapinit can forget about which + traps get an error code pushed on the stack, and which ones do + not get it. Depending on that fact, the author calls strayintrx + or strayintr to ensure the kernel stack has always the same + layout after a trap. The latter pushes the ``error code'' (the + interrupt number, actually) by software, as the hardware did + not do so. + Should the intel hardware push always the error code, + vectortable could go away and entries in the IDT point just to + strayintr or to syscallintr. + l.s:614 + For system calls, the vectortable does not call strayintr + (common trap handling), but syscallintr instead. Having a + common trap handling piece of code simplifies things (it avoids + duplicated code), but it can make you run slower. For system + calls, the call path continues at syscallintr, in plan9l.s--it + does only the strictly necessary to prepare for calling syscall + and proceed with the system call. More on this later, let's get + back to regular traps. + + strayintr() Interrupt handler (no error code pushed by the hardware). + + l.s:514 + strayintr simply provides common code to jump into intrcommon. + It pushes the trap number so that all traps have an error code + pushed in the stack together with the saved processor state. + + intrcommon() Entry point for interrupt/trap handling. + + l.s:521 + Once the stack looks the same for all traps, intrcommon saves + the data segment (which may be the user data segment) and loads + the kernel data segment (Remember that the text segment is + already ok, because the hardware did set it up as described in + the IDT.) Afterwards, data memory references refer to the + kernel data segment. This can be done because after the trap, + the processor is running at ring 0; the user cannot load + segment registers because that are privileged instructions. + l.s:528,534 + Now, after other segment descriptors are saved (user's) and + loaded (kernel's), and after the whole set of registers is + pushed in the stack,intrcommon prepares for calling trap to do + the trap processing. The stack at line :535 has the saved + processor status (made by the hardware) together with the + registers just saved. If you look at /386/include/ureg.h you + will see how: + l.s:534 + General registers (top of stack) were last pushed. + l.s:532,533 + Some extra user segment registers (fs and gs) were pushed + before. + l.s:524 and :528 + Another user extra segment (es) and the user data segment + (ds) were pushed before. And before that, as briefly + pointed out before, the trap number and error code where + pushed, either by the hardware or by strayintr. Finally, + even before that, the hardware pushed the processor + context that was going to be clobbered when the hardware + calls the trap service procedure. + The kernel has now in the kernel stack anUreg for the saved + context. + l.s:536,537 + By pushing the stack pointer, the author sets up the Ureg* + argument of trap, and finally calls trap. + The just saved user register set will be used when returning + from the trap to restore the user processor context. By + restoring it, you jump back to user code. If any register is + modified in the Ureg, it will be modified the next time the + user process runs, after returning from the trap. + + forkret() Returns from interrupt/trap handler. + + l.s:539,547 + Although a routine on its own, forkret is the code executed if + trap returns. If you look at it, it restores the processor + context from the Ureg pushed by the hardware and intrcommon. + The IRETL instruction is a very interesting one because it + reloads the processor with the context saved by the hardware on + the trap. This means that it also restores the code segment and + the stack segment and places the processor back in protection + ring 3 (i.e. userland). + + By now we skip trap handling. We will get back to it when discussing + processes. But we had a pending discussion of syscallintr. + + syscallintr() Entry point for system call trap handling + + plan9l.s:31,52 + This is the call and return path from user to kernel and + vice-versa during system calls. After the vectortable + dispatches to syscallintr there is lean (i.e. fast) code to get + the Ureg on the stack; after the call to syscall there is again + lean code until the IRETL. Compare this call path with the one + the processor would follow by going from strayintr down to + trap, and then switching on the trap number and checking some + stuff, calling syscall and back. System calls are discussed + later. The code is in trap.c:471,539 though; and it dispatches + using a system call table found at ../port/systab.c. + + The point is that after main.c:143, the kernel is prepared to service + system calls as well as other exceptions. After reading all this code, + you now know what that means. + +Virtual Memory + + We skip printinit by now, to continue with low-level glue + initialization. + main.c:148 + Interesting things begin to happen. mmuinit will initialize the + MMU data structures. Yes, the kernel already has a page table, + but it would not even be able to do a context switch. Let's see + how this thing works. + + main + mmuinit() Initializes the MMU. + + mmu.c:48 + The intel is quite bizarre at supporting processes for systems + software. It tries to do it all, and most operating systems + have to do some contortions to use what it provides whenever + they prefer to implement a different thing. This line is + allocating a ``Task state segment''. That is the data structure + used by Intel to describe a Task. It is needed because the + processor uses that ``segment'' to switch to a different + protection ring on a trap. Remember that I said that the + hardware saves the processor context on the kernel stack when a + trap happens? How does the hardware know what is the kernel + stack? It might not be your current stack when you have a + process running. + At any time, the ``Task Register'' is loaded with a descriptor + into a task state segment (TSS). It is a memory segment as any + other, but it describes the current task for the hardware. The + selector loaded into the task register selects a descriptor + from the GDT (Global descriptor table) that points to a TSS. + dat.h:109,136 + The TSS contains among other interesting things, esp0, the + stack pointer to be used at ring 0. When a trap places the + processor into kernel mode, the hardware obtains the esp0 in + the TSS loaded at the task register, and uses that stack to + save the faulting context. If the processor was already in + kernel mode, the context is saved in the current stack. + Remaining fields of the TSS contain the supposedly last saved + context for the task. On Intels, you can use a call or a jump + instruction into a TSS to switch from one task to another, and + the hardware will save the previous task context, and load the + next one. This is so slow that almost nobody uses the TSS to + implement the context switch for OS processes. In fact, in + mmu.c:20 you see how there is just one TSS descriptor for all + processes, which means that the TSS is used just to make the + hardware work. + mmu.c:51 + The GDT used until now, just for booting, is copied into the + machine structure for the current processor. The kernel is + getting out of the initial (and weird) data structures used + just to boot. The current flow of control is on its way to + become a regular process on a regular processor. + mmu.c:53,34 + The descriptor in the GDT for the TSS is updated to point to + the just allocated TSS. It will run at ring 0. + mmu.c:56,60 + Concoct a descriptor for the GDT and load it into the GDT + register. Now using the GDT for this processor. The kernel is + almost prepared to officially switch to the new TSS. + mmu.c:62,66 + Remember that the IDT was initialized at address IDTADDR? Now + the kernel loads the IDT register. Until now the kernel were + not really prepared to service traps nor interrupts--I lied. + But now the hardware knows that the IDT has some new stuff in, + because the register was reloaded. Did you notice that + interrupts are still disabled? + mmu.c:68,74 + Protections for the kernel text pages are changed not to be + writable. This could be done before while the page table for + the kernel was initialized during memory scan, but that's not a + big deal. + mmu.c:76 + taskswitch loads in the TSS of the current processor the given + stack pointer for all protection rings (and also sets the stack + segment as the kernel data segment there). It also loads in the + TSS cr3 register the given page directory pointer. cr3 is the + pointer to the page table. Besides noting it within TSS, + taskswitch loads the pdb into the processor cr3 register. Note + the ``kernel stack'' passed to taskswitch. It is the address of + the Mach processor plus the page size. The kernel stack resides + after the machine data structure. Not a big kernel stack. + Remember that such stack is given to taskswitch so that it + could initialize esp0 to point to the kernel stack for the + current task. + mmu.c:77 + Finally, the task register is loaded with the selector for the + TSS just created, and the kernel becomes an official task for + Intel. This just means that when we get up to user level, the + processor will use the right stack to service traps and + interrupts: the kernel stack specified in the TSS. + +Traps and interrupts (continued) + + main.c:149,150 + If the arch structure filled up by archinit has a routine to + initialize interrupt handling code, it is called now. If no + such routine exists, it is assumed that interrupts are already + initialized. + + main + i8259init() Initializes the PICs. + + devarch.c:377 + For the ``generic'' PC, i8259init is used as intrinit. + i8259.c:33,102 + This file contains code for the i8259 programmable interrupt + controllers (PICs). In the PC, there are two ones routing 8 + interrupts each. The two i8259s are cascaded to dispatch up to + 15 interrupts to the processor (one of the 16 ones is used to + cascade the chips). Even though the programmable timer was + initialized time ago, no timer interrupt ever reached the + processor because the intermediate i8259s were not initialized. + See figure [183]3.4. + + CAPTION: Figure 3.4: Interrupts arrive from the device though the + PICs. The PIC may mask each of the interrupt lines. The processor must + have interrupt enabled in flags to notice interrupts. + + \resizebox{14cm}{!}{\includegraphics{intr.eps}} + + i8259.c:37,38 + Allocate control ports for both chips. + i8259.c:39,102 + Comments make the code self explanatory. In any case, by the + end of the routine both chips route interrupts in their way to + the processor; The PIC is supposed to dispatch its 16 + interrupts starting at VectorPIC. The hardware uses the + interrupt vector offset to index into the IDT. Therefore, + interrupts numbered VectorPIC through VectorPIC+15 correspond + to PIC dispatched interrupts. + i8259.c:29 + The mask (i8259mask) programmed on the i8259s and the cleared + interrupt enable flag in the processor status word are avoiding + interrupts from happening. But since the kernel already has a + working TSS, IDT, and handlers for the IDT entries, it is + mostly ready to service interrupts. + main.c:151 + The PICs just initialized are used by ns16552install, which + shouldn't be called here, but by chandevreset instead. My guess + is that for kbdinit and to allow a serial line based console, + the serial line (i.e. UART) initialization is being done here, + or maybe this is a fossil if any time back in the past devices + were initialized right from main. Although the code is still + clean and easy to follow, it could be an alternative to place + most regular initialization routines under the control of + chandevreset, and let it resolve dependencies. But that could + also be a recipe for disaster if the (generated) chandevreset + code would not honor dependencies. Forget this brief guess if + you didn't understand, it is not relevant. + + main + ns16552install() Sets up the uarts. + + ns16552.h:82,111 + ns16552install allocates ports for the serial lines (two ones, + eia0 and eia1). Then ns16552setup initializes the two UARTS. + ns16552.h:99 and :103 + intrenable is called to request that IrqUART0 and IrqUART1 + interrupts be enabled (not masked by the PICs) and handled by + the ns16552intrx routine. We'll get to intrenable a bit later. + ns16552.h:106,110 + If plan9.ini said to use a serial console, setup the specified + serial port so that its input and output queues are used for + kbdq (the queue for keyboard I/O) and printq (the queue for + console output I/O, as we saw before). ns16552special sets the + pointers passed (kbdq and printq) to point to the Uart + input/output queues. So, anyone reading from the ``keyboard'' + will be reading from the Uart input queue, that will in turn be + written by the serial line driver as characters come in. The + rest of ns16552intall simply initializes the several kinds of + serial boards you may have installed. We will ignore that. + + main + ... + intrenable() Enables an interrupt and installs its handler. + + trap.c:19,57 + Going down to intrenable, it enables the interrupt irq after + setting up an Vctl structure for the interrupt. Although we did + not look into trap, note that it is also called by interrupts, + which are handled like traps. The trap function uses a Vctl + array to index with the trap number and obtain a ``vector + control'' structure to learn how to handle the trap--more + generic programming. + io.h:44,56 + Among other things, the Vctl structure holds the interrupt + number, a tbdf field which identifies the place of the device + in the bus hierarchy, and a pointer for the interrupt handler + f. The handler admits an argument and there is a place for the + argument (a) in the Vctl. When an interrupt (or trap) happens, + trap takes the Vctl and calls f(a). That is an easy way to + reuse a given f by supplying different arguments to it. + trap.c:24,31 + A newly allocated Vctl is initialized. The name supplied to + intrenable is stored in v->name. That way, the kernel (and its + users) can know who allocated the interrupt. The interrupt + number, handler, and its argument are stored too. In our case, + name would be eia0 or eia1, and the argument for the handler + would be 0 or 1--telling ns16552intrx which one of the two + UARTS is interrupting. + trap.c:33,34 + Locking the Vctl to avoid someone changing the handler under + our feet, call the architecture specific intrenable supplying + the Vctl. + + main... + intrenable + i8259enable() Enables an interrupt in the PIC. + + i8259.c:131,147 + For the ``generic'' architecture, intrenable is i8259enable. It + updates the i8259mask and installs it on the PICs. The + interrupt number is checked to be valid. + i8259.c:148,152 + Also, if the interrupt is not level-triggered (it is + edge-triggered) it is not allowed to be shared. Shared? Yes, + look at the Vctl and see how there is a pointer for a next + handler. On the PC, interrupt numbers are scarce, and devices + may share them. The kernel will call the drivers sharing the + interrupts, and they should cooperate to determine which one + was actually responsible for the interrupt. + i8259.c:153,157 + Here is where the new interrupt mask is programmed, and the + interrupt is enabled. It is now passing through the PICs from + the device to the processor. If the interrupt enable flag is + set, the processor may be interrupted now by this interrupt and + trap will call its handler(s) using the Vctl(s). + + main + + main.c:152 + mathinit enables some traps and interrupts, used by the + coprocessor to notify FPU (Floating point unit) errors. + mathinit()Enables FPU traps/interrupts + main.c:552,559 + Calls to trapenable and intrenable would be setting up Vctl + structures to let trap know that the kernel is prepared to + service FPU related events. + main.c:153 + kbdinit (in kbd.c:397) allocates ports for the keyboard, as + well as the keyboard interrupt. After consuming any character + from the keyboard (from the impatient user) it enables the + keyboard interrupt.

For us, it is i8253enable that enables the clock + interrupt using clockintr as a handler. Clock ticks from the + programmable timer are now arriving to the processor. clockintr + will be discussed later; it is the heartbeat of the system. + + Setting up I/O + + main + printinit() Initializes console output. + + main.c:144 + the call to printinit initialized the queue used for print in + the console. What? the queue? Let's see that. + /sys/src/9/port/qio.c:25,49 + Time ago, Plan 9 used Streams [[184]15] to do I/O. The data + structure found here, is the distilled replacement for Plan 9 + 3rd edition. It defines a Queue. A queue is the structure used + to read/write bytes from/to a device or any other kernel beast. + The author uses that because it would not be good to block a + process writing on the console just because it takes a long + time to put bytes in the serial line. It is better to place the + characters in a queue and, when the line is ready, process them + and put the bytes through. This is an example, but there are + many similar situations and I hope you get the picture. + qio.c:29,30 + Queues hold Blocks. A Block is a buffer waiting for I/O. Some + part of the kernel puts a buffer in a queue, and another part + is expected to consume the buffer some time in the future. + portdat.h:123,135 + Block is defined here, and provides pointers (next and list to + link up blocks sitting in a queue). base points to the start of + the buffer, and lim determines the end of the buffer. The other + two pointer rp and wp are the read pointer and the write + pointer. Routines writing to the Block advance the write + pointer, and routines reading advance the read pointer. The + portion of the buffer still to be read lies between rp and wp. + Note the pointer to a free routine. The allocator of a Block + can supply the buffer from whatever memory allocator it chooses + (maybe just static memory), and set free appropriately so that + when the buffer is no longer used memory is released. + qio.c:32,35 + These values summarize the memory held by the queue (i.e. by + the blocks in the queue). + qio.c:43,46 + These locks are used to queue processes waiting for data to + read in the queue, as well as processes waiting for buffer + space in the queue so they could write. + Now let's see a bit of the implementation. + qio.c:74,364 + Several routines provide the programmatic interface for Blocks. + They are all you need to manipulate and access the buffering + provided by the Blocks. They know that blocks are linked + together. + qio.c:370,403 + qget is a routine called by readers of a queue. + qio.c:375,383 + After locking the queue, it sets its state to Qstarve if there + is no data to read, and returns a null block. + qio.c:384,387 + If there is a block to read, it is removed from the queue. + qio.c:390,396 + When the state is Qflow (the writer was stopped because it was + writing too fast), and the queue has less than half its + capacity, the writer is awakened (it will continue and write) + and the Qflow flag is removed so that any other write can + proceed. + + We saw this to get a flavor of I/O using queues, but we'll see queues + in chapter [185]5 that discusses files and I/O. + + Preparing to have processes + + The kernel has almost booted, and we have gone a long way already. You + now know a bit of the data structures used and how the system glues to + the hardware. The things to come are more interesting and a bit + higher-level than what is past. + + ../pc/main.c:156 + procinit0 should be called actually procinit, but there is + another routine with the same name. + procinit()Initializes the process table. + ../port/proc.c:386,400 + it creates a process table containing the number of processes + initialized previously in conf. All process table entries are + linked into a free process list. Each entry contains what the + system knows about a particular program in execution. + initseg()Initializes allocation for segment (images). + ../pc/main.c:157 + Processes need (program) images to run. initseg initializes the + Image allocator in ../port/segment.c by doing the same other + allocators do: Images are allocated and linked into a free + list. You will learn later what is an image. + + Devices + + main.c:158 + links is called to initialize devices. However, there is no C + source file with a links function definition. What happens + here? + ../port/portmkfile:45,46 + the script mkdevc is called to generate 9pcdisk.c from 9pcdisk + or any other configuration file. + mkdevc + generates a source file from the configuration file (i.e. the + value of the $CONF variable as given to mk). + What does it generate? Let's look at both pcdisk and pcdisk.c. + ../pc/pcdisk.c:9,31 + First, external Dev structures are declared for entries under + (i.e. indented below) ``dev'' in pcdisk. You see, rootdevtab + for root, consdevtab for cons, etc. What is a Dev? By now, + think of it as a bunch of procedures (i.e. pointers to + functions) describing how to operate on a device. The + interesting thing for you now is that they have a reset + procedure. To pick up one, etherdevtab is declared in + devether.c:431,450, and it contains a reference to etherreset. + pcdisk.c:32,57 + Now, a devtab array with pointers to Dev structures is built by + mkdevc, it is null terminated. + pcdisk.c:59,66 + For entries in the configuration file named *.root, *code, + array declarations are generated together with a length + variable (The actual arrays are not being declared now). Looks + like ``.roots'' need this to get initialized; but forget this + now. + pcdisk.c:67,76 + This is the interesting thing for us now. For each thing in the + conf file under link, an external thinglink function is + declared. That is our initial entry point for ethernet and + communication devices. The convention is that a thing.c file + would contain the thinglink function. By generating this code + automatically, to add a new ``linked'' device, the author only + needs to write a new C source file, add the entry for the + device in the configuration file, and recompile the kernel. Of + course, the scripts won't work unless the author follows name + conventions. + + main + links() Links device drivers into other drivers. + + pcdisk.c:77,92 + The generated links function, calls the link procedures for the + ``link'' devices configured into the kernel. What are links? + Well, you see how most entries under links are for ethernet + cards; concrete ethernet drivers can be linked to a generic + driver supplying the common functionality. You get the picture. + (Note also how for *.root entries, a call to addrootfile is + generated. That is initializing some kernel-supplied ``files'' + used to get the system working; More on this later). + ether8003link()Links the WD8003 ethernet driver + ether8003.c:267,270 + For ether8003, you only have to go to file ether8003.c and look + at function ether8003link (saw the name convention?). If calls + addethercard supplying a card name and a pointer to a reset + procedure. + addethercard()Links and ethernet ethernet driver + devether.c:302,311 + addethercard is simply registering (linking!) the card into a + table with configured cards. Later, the reset procedure of the + card will be called to prepare it for use. We don't discuss it + here, but devether is a generic ethernet device that uses + services of concrete ethernet card drivers. For instance, the + kernel uses devether to start and stop ethernet cards, and + devether uses Ether structures to locate procedures for + starting and stopping the concrete ethernet card involved. + How is the Ether structure being filled up? When later, + devether calls the reset procedure registered by addethercard, + it is supplied an Ether structure that it must fill up. + Starting to see how things fit together? + pcdisk.c:95,98 + Just for curiosity, see how the knownarchs array mentioned + before is also generated. For our local configuration, the only + specific architecture is that for Intel based multiprocessors; + everything else is a regular PC. + main.c:160 + now that generic devices have their concrete devices linked + into, call chandevreset. + + main + chandevreset() Resets device drivers. + + ../port/chan.c:50,56 + Forgetting about the ``chan'' thing, chandevreset iterates + through the devtab generated by mkdevc and calls all reset + procedures. That prepares each device for operation. As one + device may depend on another, the configuration file has (at + the right of the line configuring a device) the name of + ``it-depends-on'' devices. mkdevc must honor dependencies when + generating devtab. + etherreset()Resets the ethernet ethernet driver + ../pc/devether.c:337 + Using again our ethernet card as an example, etherreset may + look rather complex for us now, but it just tries to detect + (linked) ethernet cards and prepare them for operation. + devether.c:361,362 + This is where reset for the ethernet card linked before is + called. The purpose of this routine is to try to detect cards, + and initialize any interface (i.e. shared memory between the + host and the card, or I/O ports, or whatever) used to talk to + them. If a card is detected, reset should say so with its + return value so that devether knows whether there is yet + another ethernet card or not. + ether8003.c:71,142 + Most of the code of reset has to do with playing the dance from + the card manual to determine if the card is there and what kind + of card is it. + + Files and Channels + + . + + First a quick remark, I am still discussing initialization carried out + by main. But since files and channels are so central in Plan 9, let's + say a bit about them before continuing with the source. You are + advised to read intro(2) until the point where processes are + discussed. Manual pages for system calls mentioned below are also + relevant. + + In Plan 9, a file is an entity serviced by a server process over the + network. That is a generic definition. Of course, the ``server + process'' can be the kernel, or a user process, and the ``network'' + may be some kernel code to glue a local, in-kernel, file server with a + local user of the file. Note that ``local'' here means ``within the + same node''. + + Files are used with the traditional unix interface: create, open, + close, dup, read, seek, and write. And files are still (as they were + in UNIX) a (named) sequence of bytes. Files are deleted with remove + (kind of UNIX's unlink, but a bit different). stat and wstat are used + to read and write file attributes. Directories are read like files, + but they are written either by using dirwstat to change attributes of + a directory entry, or by using create or remove (they add and delete + directory entries for the file affected). + + This (procedural) definition of what is a file, refers to procedures + that can be applied to files, either to obtain new files or to + manipulate and destroy them. However, when there is a network between + the file and the file user (the caller of the procedures), something + has to be done instead of calling the procedure with a procedure call. + + What Plan 9 does is to translate calls to file procedures in the + client machine to RPCs to the server. In case you didn't know, an RPC + is a remote procedure call. It works by sending a message from the + client to the server when a procedure is called, and receiving later + another message with the procedure result. The steps are mostly as + follows: + 1. + The client (the caller of let's say, write) calls the procedure + (write). + 2. + A piece of code (stub) in the client implements the local + procedure actually called by the client, but that is not the + real procedure being called. The client stub builds a message + with the identifier of the procedure being called, and a copy + of the parameters passed to the procedure. + 3. + The client stub sends the message to the server process (the + one implementing the procedure being called). + 4. + The server process is a process listening for messages + requesting procedure calls. It receives the message sent by the + client. + 5. + The server process unpacks the message and determines the + procedure to be called. Depending on the procedure being + called, the server knows what parameters are in the message, + and unpacks them. + 6. + The server process calls the actual procedure (write) with the + parameters just unpacked. + 7. + The procedure returns, yielding some results. + 8. + The server process builds a reply message with the procedure + result. + 9. + The server sends the reply message back to the client + 10. + The client stub receives the reply + 11. + The client stub unpacks any output parameter and result + received, and returns pretending that it was the stub the + procedure that computed the result. + + Now, the protocol defining the request (called transaction in Plan 9) + and reply messages to perform operations on Plan 9 files is called 9P. + It is defined in section 5 of the manual. It is a protocol, and not a + bunch of unrelated RPCs, that means that both the client and the + server using 9P are expected to follow 9P rules. You can take a look + at intro(5) to see what's going on. + + How does the client get in touch with the server to issue 9P requests? + 9P does not specify that--read: 9P permits you to use any way you can + imagine to get in touch with the server. You are expected to get a + network connection between the client and the server by any other + means. Once you have the connection, the client and the server can + talk 9P on it. + + For remote files, the connection is likely to be either a TCP or an IL + stream (IL is the Plan 9 transport of choice) over an IP network. For + local files, you still have a ``connection'' between the client and + the server. I'll now describe this one. + +Using local files + + The client is your local machine. Consider a process calling a file + procedure like write, it specifies a small integer (a file descriptor) + representing the file where to write. File descriptors are obtained + with open as in UNIX. + + /sys/src/9/port/portdat.h:555 + The kernel knows which one is the current process, and locates + the fgrp field of its Proc structure. The fgrp points to a File + Descriptor Group structure. See figure [186]3.5. + + CAPTION: Figure 3.5: The user uses file descriptors (indexes into the + Fgrp descriptor array) to specify files; but the kernel uses channels + to point to routines knowing how to perform file operations. + + \resizebox{14cm}{!}{\includegraphics{files.eps}} + + portdat.h:431,437 + The Fgrp contains an array of pointers to Chan. Every Chan + represents a file being used, and every file descriptor is just + an index into the array in the Fgrp. open allocates a new entry + in the Fgrp and places a Chan on it. The index for the entry is + given to the user as the descriptor for the file just opened. + + We know what is a file from the point of view of the client (a + descriptor), but where is the server? and where is the file on the + server? The answers reside in the Chan structure, with a bit of help + from other structures elsewhere. To answer the questions, let's follow + a bit of the path that a write system call walks. + + syswrite() write system call. + + sysfile.c:444 + syswrite is called, with arg holding a file descriptor, a + pointer to a buffer, and a number of bytes. + sysfile.c:452 + fd2chan translates the (integer) file descriptor into a Chan + structure, by looking at the Fgrp for the current process. + sysfile.c:453,468 + Ignore this by now. It is for handling directories and checking + errors. + sysfile.c:469 + Here it is! The type field of the Chan structure is used to + determine the kind of device implementing the file (the device + can be just ``software'', of course). Now, by indexing with + type into devtab, the author gets a reference to the Dev + structure for the device implementing the file. + Say that ``file'' is a printer, the pointer to a Dev structure + found at devtab[type] would be a pointer to lptdevtab, the Dev + declared at ../pc/devlpt.c:209,228. This is because the type in + channels pointing to local printers is simply the index in + devtab for the lptdevtab entry. + Now, still in ../port/sysfile.c:469, the procedure pointed to + by write in devtab[type] is called. If you look at lptdevtab, + it is lptwrite the procedure actually called. lptwrite is given + a pointer to the Chan for the file being written. Besides, note + how the offset where to write in the file is taken from the + offset field of the Chan. You can see how a Chan in Plan 9 is a + reference to a server file. You also start to see some + implications, like that to share a file offset, the Chan must + be shared, which means that processes sharing the Chan must + reside on the same machine. + + syswrite + lptwrite() Writes on a file in a lpt device. + + ../pc/devlpt.c:148 + In our example, lptwrite gets called, with the Chan for the + file. + devlpt.c:155 + At this point, something interesting happens. The lpt driver + (the file server in this case) takes the qid field from the + Chan. The QID identifies the file in the server. It only has + sense within the server. Here, the server is just the local + printer driver, and the driver is checking the QID to see which + files should be written (it services several files). + The QID is made of two numbers, path and vers. Actually, it is + path that identifies the file. In this case, path holds the + value Qdata for the printer data file. But it could be any of + Qdlr, Qpsr, and Qpcr for files with names dlr, psr, and pcr + also serviced by the printer driver. Two files (within the same + server) are the same file if they have the same path value in + their QIDs. This means that a client of the file server can + check if two Chans refer to the same file by checking their + paths (assuming the files are within the same server. If a file + is removed and created, it should get a new path. + The vers field of the QID is used to distinguish different + versions of the file. It is useful because someone might be + caching a file, or might like to know if the file has changed + since it last got its QID. + Two files are exactly the same file, and thus have the same + contents if they reside on the same server and have the same + QID. This is also important for caching. If a cache has a copy + of a file, and the server still has the same QID for that file, + there is no need to refresh the file copy in the cache: it is + the same one! + devlpt.c:165 + Another interesting thing happens. There can be several + printers. Which one is the one used for write? The Chan + structure has a dev field that specifies which particular + device is being used. So, type and dev fields together identify + a device in the kernel. The type field of the Chan is used to + select the appropriate implementation for file operations, and + the dev field is then used to select the appropriate device of + that kind. + + So, what is a file for the client process? A file descriptor that + leads to a channel. Where is the server? The type and dev fields of + the channel know. Which one is the file? The qid field of the cannel + knows. + + An what about remote files? For remote files, (not discussed now), the + type field would select mntdevtab among devtab entries. mntdevtab + (devmnt.c:920,939) is the Dev for the mount driver, a driver that + implements device operations by issuing RPCs to the server process. + The mount driver uses the connection to the server supplied by the the + caller of mount(2) to talk 9P with the server implementing the remote + file. + +Starting to serve files + + Going back to main, the kernel is already servicing some files (see + root(3)). + + ../pc/main.c:158 + main calls links + ../pc/pcdisk.c:78,81 + which calls addrootfile for cfs, kfs, and ppp. + main.c:160 + main also calls chandevreset, which calls reset for configured + devices, including a call to rootreset: the reset procedure for + rootdevtab. + ../port/devroot.c:78,90 + rootreset is simply calling to addrootdir and addrootfile + several times. + + So, main makes multiple (indirect) calls to addrootfile and + addrootdir. Let's discuss them now. + + ../port/devroot.c + This is the ``device driver'' for the root of the file system. + It services a flat directory implementing the well known ``/'' + directory. + + main + ... + addrootfile() Adds a new file to the root device file free. + + devroot.c:62,66 + addrootfile ``creates'' a new file in the directory serviced by + the root device. addroot()Adds an entry to the tree. + devroot.c:46,47 + At most Nfiles can be placed in the directory serviced. + devroot.c:48 + This is a admittedly simple file system. When other parts of + the kernel create a file into devroot, they supply file + contents as well. Remember buffers named cfscode, kfscode, etc. + declared by mkdevc? + rootdata (devroot.c:19) is an array of pointers to the data of + the (at most Nfiles) files serviced. So, addroot uses the first + free entry to plug the file contents in. There are nroot files, + from 0 to nroot-1. + Where do file contents come from? Consider for example the + kfscode array. The mkfile is calling ../port/mkroot using kfs + as an argument, which is calling data2s. data2s takes a binary + from the running system where you are compiling the kernel + (kfs, which is a program), and generates an assembly file + (kfs.root.s) with the definition of an array (kfscode). The + array contents are the contents of the file. That file is later + assembled and linked into the system. That is how regular + Plan 9 binaries are linked into the kernel to be used as ``root + files''. You can imagine that root files are files needed to + boot the system (i.e. to connect to a true file system, etc.) + and cannot be loaded from the disk/network file system (chicken + and the egg problem). + devroot.c:49 + That was the contents, and the name, permissions, etc? rootdir + is an array of Dirtab structures, containing attributes for the + files serviced. In Plan 9, attributes reside within directories + (well, they can reside at any place the file server wants to + put them at). So, d is the pointer to the directory entry for + the file being ``created''. + devroot.c:50,52 + File name, length, and permissions are set in the directory + entry for the file. + devroot.c:53 + Crucial! a QID for the file is invented. For devroot, files are + numbered 1 to Nfiles, so that file i resides at rootdata[i-1] + and rootdir[i-1]. Clients using the directory serviced will + obtain QIDs for their files and pass them back to devroot when + requesting a file operation. The server must be able to locate + the file quickly given its QID. An index is a just fine way. + devroot.c:54,55 + In Plan 9, directories are also created with create, as files + are. When the CHDIR bit is set in the permissions given to + create, the file server understands that it must create a + directory; not a file. It is the convention in 9P (yes, 9P) + that the path component of QIDs have the CHDIR bit set for + directories. So, these two lines of devroot.c are adjusting the + QID of the file to look like a directory in case the + permissions said to create a directory. + devroot.c:56 + The number of created files is incremented. The next time a + file is created, it would be placed in the next entry. + devroot.c:62,75 + Pay now attention to the arguments given to addroot in both + addrootfile and addrootdir. Understood? Well, it's true, I + didn't say that directories have by convention 0-length. + devroot.c:80,90 + The calls being made by main to the root driver are simply + populating the root device with empty directories holding + nothing. But now that there are directories, they can be + populated! + However, although devroot is prepared to service its files, no + one has a ``connection'' to devroot yet. Well, as devroot is + local, I mean that no one has a Chan with the type set so that + devroot will service the file at the other end. + +Setting up the environment + + Most of the environment for the first user process, and the ones to + come is provided by files. For instance, environment variables, names + for the host, the user, etc. are provided by files serviced from the + kernel. Now that you understand a bit of what does this mean, let's + enumerate some files implementing part of the user's environment. If + you want a user's description of what is provided, refer to manual + section 3. It describes devices that service file trees from the + kernel, as root does. You should read intro(3) at least. + + Take a quick look at any of them and don't be worried too much if you + don't understand what is going on. Some of them (eg. env) are fairly + easy to understand though. + ../port/devcons.c + implements the console device. It supplies files for console + I/O and also for other diverse tasks like user authentication, + time of day, rebooting, etc. + ../pc/devarch.c + We saw a bit of it. It supplies files to identify the + processor, see allocated irqs and I/O ports, and files to do + I/O from user processes. + ../port/devenv.c + Provides environment variables. They are serviced from the + kernel as files in Plan 9. + ../port/devpipe.c + Pipes + ../port/dev....c and ../pc/dev...c + and many others. + + I will comment some kernel drivers through this commentary, as I did + with the root driver. + + Memory pages + + After our incursion into the files serviced by the kernel, we are back + to main. + + You are assumed to have at the very least some concepts on virtual + memory from a basic operating systems or architecture course. You + don't? I think you will survive, but study that topic a bit... + + ../pc/main.c:161 + Just initialized the device files, but have more work to do. + Now pageinit initializes page (frame) allocation, to prepare + for paging. + + main + pageinit() Initializes the page allocator. + + ../port/page.c:13 + pageinit has the important task of initializing the palloc page + allocator. Right now the kernel cannot create a process because + it can not allocate pages for its code, data, and stack; not + yet. + portdat.h:444,459 + The page allocator holds a Page structure for each available + page frame known by the system. You can image that it is a big + data structure--in fact, remember that when calculating + available kernel memory the author had to take into account the + size of this array. By now, see how it looks: looks like the + allocator implements LRU for free pages. + portdat.h:279,293 + The Page structure keeps for each one the physical address in + memory, virtual address for user, and disk address on a file. + It also has a virtualized copy of the modified/referenced bits + maintained by the MMU. Page contents come from either a file or + a swap file, image points to that. If you look at Image you see + how it contains Pte structures that keep pointers to Pages. + Don't be worried. It's simple: pages are either in use by + in-memory images of files or they are free in the palloc array. + page.c:19,20 + A big Page array is allocated at once for the number of pages + defined in np0 and np1 in palloc. Both np0 and np1 were + initialized at xalloc.c:77,78 with the number of pages + ``eaten'' by xalloc from the two memory banks defined in the + conf structure. + See how the author fights fragmentation? It has no sense to + allocate and deallocate Page structures as they are needed. + There will be at most as many free pages as free page frames at + boot time. The author allocates a big array, and then links + Pages on the appropriate list--Images or palloc as they are + allocated/released. + + Lesson: To avoid fragmentation, avoid using dynamic memory whenever + possible. Allocate many resources at once and then keep on using + them. + page.c:21,22 + More defensive programming. You must have enough memory for the + page array, but maybe you don't. + page.c:24,36 + One page at a time, bank 0 pages are linked into the free list. + p0 is kept pointing to the physical address where a page is + being ``moved'' to the free list; np0 has the number of pages + in bank0 not in the free list; and freecount has the number of + pages in the free list. + color has to do with caching. Two different pages can have a + cache conflict because both ones collide on a cache sitting + between the page and the page user. For instance, think that + even pages use entry 0 in the processor cache, and odd pages + use entry 1. It is better to use pages 3 and 4 than it is to + use pages 3 and 5. Got the picture? + The algorithm uses NCOLOR ``colors'' to ``paint'' the pages. If + a page is ever allocated for a given user, and that user has + color ``1'', it is better to give him a page of color ``1''. + That is because pages of the same color are far apart in the + memory and the author assumes that the bigger the distance two + pages are at, the less the chance they will collide. + page.c:37,47 + The same is done for pages on bank 1. + page.c:48,50 + The list is set. + page.c:52 + The number of pages for the user is the distance between the + head and one past the tail. + page.c:52 + The size of the physical memory in Kbytes is computed, just for + letting the user know. + page.c:53 + Remember the nswap ``limit'' set when the kernel first knew how + many pages would be available? That was actually the maximum + number of pages not found in-memory. By adding the physical + memory size, you get the virtual memory size. This is just to + let the user know. + page.c:57,58 + These two values are used for paging. Eg. when less than a 5% + of pages are free, the kernel should be moving pages to disk, + to make more room. It is not healthy to let all the pages be + occupied. It could be that (due to some bug) the kernel needs + free memory for the algorithm that gets more free memory... + + main + swapinit() Initializes the page allocator. + + ../pc/main.c:162 + Back to main, swapinit initializes swapping. + ../port/swap.c:21,33 + Set swapimage.notext; which means that there is no swap file + yet. Perhaps an explicit initialization would make things more + clear: swapimage has been initialized to all-zeroes by the + loader. Its c member that points to the Chan for the swap file + is still zero, which means that there is no channel to the swap + file. In any case, a ``swap map'' (swmap) is allocated. It + reflects the state of portions in the swap file. A page array + for the max number of pages being paged out to swap + (conf.nswppo) is also allocated. + + The first process + + You should know already what a process is, at least from a theoretical + perspective and as a user. To remind you, Plan 9 can use a machine + with just one CPU and pretend that there are multiple programs + executing at the same time. The way to do it is to let each program + run a small fraction of time. As the processor is fast enough, if + programs are given small fractions of processor time repeatedly, they + would appear to be executing all at the same time. A program in + execution is called a process. + + A process is more than a program, it has open files, is run on the + name of a user, has memory for data allocated while the program is + running, a stack to keep track of nested procedure calls and to + maintain local variables, etc. + + To multiplex the processor among processes, a timer interrupt is + typically used. The system arranges a timer to interrupt the + processor, say, 200ms in the future, and loads the processor context + with register values appropriate for executing the user process code. + When the interrupt arrives, the hardware (and the interrupt handling + software) saves the context of the processor as it was right before + the interrupt. That set of registers, if reloaded, would permit the + process to continue where it was. But usually, the kernel loads the + context of a different process instead, letting it run for another + quantum of 200ms in this example. At some time in the future, the + saved context for the process in this example would be reloaded and it + will not even know that another process was using the processor + before. + + In a previous section, you were advised to read intro(2) until the + point where processes are discussed, now go and read all of intro(2) + and fork(2). Most of what the code you are going to read is doing is + also described at boot(8). You are also advised to refresh your + ``theory'' of what a process is in case you are lost by this point. + + From now on, I will be describing some important fields of the process + data structure. I suggest you try to guess how they are used. One fine + way of doing it is (after reading the manual pages I suggested) using + grep on the source to see where are those fields used. Try to guess + what is the field being used for. + +Hand-crafting the first process: The data structures + + Right now, Plan 9 is just a flow of control running a program (the + kernel) loaded into memory. That is not enough to provide system + services, there should be a real process that could later use + rfork/exec to create new ones and execute other programs. + + You can see figure [187]3.6 to get a glance of how our current flow of + control will evolve into a set of processes. In the figure you see how + initially, the kernel started executing and then it creates the memory + image for a first process. It will later jump to protection ring 3 to + execute the user code for it. After that, the kernel would only + execute to service interrupts and system calls--(in the mean time the + process would be ready to run, but would not be running). This first + process would make rfork system calls to create new processes, and the + clock interrupt will be used to multiplex the processor among existing + processes. + + CAPTION: Figure 3.6: The kernel is just a program, and there is just a + flow of control. However, users believe that their processes are + executing sequential programs. + + \resizebox{14cm}{!}{\includegraphics{procs.eps}} + + ../pc/main.c:163 + About to call userinit in main. It is the procedure that + creates the first user process. After that is done, what + remains is to jump to that process and let the system run when + interrupts, exceptions, or system calls request any system + service. + + main + userinit() Initializes the user environment and creates the first + process(es). + + main.c:236 + Previously, the kernel allocated an array with Proc entries. + That was the process table. Each entry is a Proc struct with + the information needed to implement processes. For example, the + Proc structure is used to get to the saved processor context + needed to put that process back in the processor. Now the + author allocates a free entry in the process table. That entry + will be filled up to initialize (create) a new process. + + main + userinit + newproc() Allocates a process table entry. + + ../port/proc.c:307,314 + newproc waits until the free list has at least a free entry. + The resrcwait call would make the current process wait due to + the specified reason (``no procs''); it would be preempted or + moved out of the processor. Think that the current process, + willing to create a new one, has to wait until a free entry be + available. By the way, what is the current process? By now, + none. However, there are free entries and we break the loop at + line :309. The kernel is creating the first process and by now + there is no current one. Note the use of the loop around the + wait, because there is no guarantee that by the time the + current process gains the lock in line :313 any free entry be + still there. Another process could run instead, gain the lock, + and allocate the just released entry. + proc.c:315 + The process entry is removed from the free list. p is the + process begin created. + proc.c:318 + This will be clear when we discuss processes in chapter [188]4. + Processes have a ``state''. The process state tells the system + on what condition the process is in. In this case, the process + is being handled by the scheduler, the part of the system that + decides who runs next and switches from one process to another. + portdat.h:493,504 + You should recognize at least the typical states Ready and + Running. To get an idea of how state is used, consider that + dead processes (those that terminate or abort) have their state + set to Dead; functions doing things to processes while they are + alive can check that the state is Dead and do nothing to dead + processes. + proc.c:319 + This is the state name as printed by ps(1). It is a new + process. psstate holds a representative string for the state + the process is in. That can effectively turn ps(1) into a + debugging tool. It also permits you to inspect a process from a + different machine, psstate would make sense even on a different + architecture: It is just a string that is understood + everywhere. + proc.c:320 + mach points to the Mach structure of the processor where the + process is running. Did not run yet. It is necessary to know on + which processor the process is running at, because on that + processor is where the actual process context is (while a + process is running, the set of registers last saved for him by + the hardware is irrelevant). The convention is that mach is + zero only when the process context is saved elsewhere and its + user code is not running. + proc.c:321 + Not on the free list anymore. + proc.c:324 + This is discussed in the chapter for processes. It is used to + make the process wait due to some reason. Not waiting anything + now. + proc.c:325,328 + Some resources used by the process cleared. Let's say something + about it now before continuing. + + Take a coffee, go read rfork(2) (reread intro(2) if you forgot), and + come back later. + + proc.c:325 + Processes have a name space. More precisely, processes are + within a process group and process groups have a name space. + pgrp is a pointer to a Pgrp structure representing the + ``process group''. For me, the initial ``p'' is confusing + because it sounds like ``process'' and not ``name'', but the + author would have a good reason for the name. The name space + determines what names lead to what files. Actually, the name + space is very similar to that of a UNIX machine. In UNIX, there + is a mount table (for the whole system) that specifies paths + that lead to file systems. For instance, ``/'' leads to the + root file system, ``/cdrom'' may lead to a file system on a + cdrom, etc. Now, back to Plan 9, every process has a name + space. The name space is made of a mount table that associates + paths to file systems. For example, one thing the first process + will do is to associate ``/'' to the root file system + implemented by the root device. + The interesting thing in Plan 9 is that every process (group) + has its own name space and can add and remove entries without + affecting other processes. Adding a new entry is called + mounting a file system or binding a file (see mount(2)). + Deleting entries is called unmounting a file system. + This is very important because it provides an engineering + solution to several important problems on distributed systems. + For instance, by binding /$objtype/bin onto /bin, each process + will find appropriate binaries for the current architecture; + binding files under /dev is a fine way to make a particular + process see a different device-perhaps at a different node! + Processes can share their name space (i.e. their process group) + too. That means that several processes may have the same value + in their pgrp field. + proc.c:326 + Processes have environment variables. Both variables and values + are strings. An example of an environment variable is PATH + (which, by the way, is mostly unused in Plan 9). Again, each + process has its own environment (made of a set of variables). + egrp points to an Environment Group or Egrp structure. + portdat.h:413,429 + It maintains variable names and value strings. Several + processes may share their environment; egrp may be the same for + more than one process. + proc.c:327 + Processes have open files. As we saw before, each process has a + file descriptor group. fgrp points to an Fgrp structure. + portdat.h:431,437 + It has the set of file descriptor entries for the process. You + already know that each file descriptor leads to a Chan + structure that is all you need to perform an operation to the + file referenced by the Chan. Again, processes may share their + file descriptor group. Several processes may have the same + value for fgrp. + proc.c:328 + Processes can synchronize by using rendezvous(2) . To + rendezvous, processes call rendezvous supplying a tag that must + be the same for the two processes doing the rendezvous. Tags + are actually local to a ``process rendezvous group''. rgrp + points to a Rgrp structure. + portdat.h:407,411 + This implements the rendezvous group. It is obvious that + processes can share their Rgrp. + proc.c:329 + Sometimes, a process gets broken and has to be debugged. The + debugger is another process that controls the execution of the + debugged process by placing breakpoints, altering the debugged + process state, and processing events of interest for debugging. + pdbg in a process being debugged points to the debugger process + Proc structure. + proc.c:330 + This has to do with how math coprocessors work. It is really + expensive to save and reload the coprocessor context. + Therefore, the system tries to avoid unnecessary coprocessor + context switches by not loading the coprocessor when a process + does not use it. fpstate records the state of the coprocessor. + The author uses it to know if the coprocessor is being used. By + now, it was not even initialized to a reasonable state. FPinit + says so. + proc.c:331 + You probably think that all processes execute user programs, + running with the processor in non-privileged mode (ring 3). And + that these processes enter the kernel only to service an + interrupt, a trap, or a system call. That is not true. There + are processes that spend their lives within the kernel. These + are called kernel processes. For example, in Plan 9, there is a + process called ``pager'' that has the important task of doing + page outs when low on free page frames, by stealing page frames + from other processes. This is better implemented as a process + with its own (sequential) flow of control that mostly sleeps + until a point when it starts moving pages to disk. You can + imagine that to move pages to disk, the process must do I/O and + must have special privileges, since it must have access to the + pages for the processes involved. For both reasons, it is + implemented as a process that never leaves the kernel, it + starts executing a at a given function within the kernel. After + that, it is handled as a regular process--with special + privileges, admittedly. kp is true when the process is a kernel + process. + proc.c:335 + Processes move. They move from one processor to another. This + is important because if a process has just run at a given + processor, the processor's cache will still have cached memory + for the process. It is much cheaper to run this process again + on that processor than it is to run it at a new one: The new + processor will remove from its cache other memory and it will + have to move in new entries for this process; besides, the old + processor has now unuseful cached memory. movetime keeps the + earliest allowed next time for a move, to help in taking into + account ``processor affinity'': a process has affinity for the + processor where it did run last time. + proc.c:336 + Processes can be wired to a processor, so they always run on + it. wired points to the Mach structure for the processor where + the process is wired to. + proc.c:337 + ureg points to a saved Ureg for the process used for notes. + Forget this now if you don't understand. + proc.c:338 + error maintains the error string for the process (see + errstr(2)). Errors are represented by strings (portable, + readable) in Plan 9. They are set either by errstr or by a + failed system call. + proc.c:339 + Processes have a virtual address space. That means that + different processes have different page tables and their + virtual to physical address translations differ. In Plan 9, the + user part of the address space (what the user process sees) is + organized as a set of segments. Every process has a TEXT + segment with the code, a DATA segment with its data, and a + STACK segment with the stack. There are other segment kinds + like BSS, for uninitialized global data, etc. Some of them are + initialized later for this handcrafted process. + Processes may share segments, although some segments, like + stacks, are not shareable--that would make no sense. The + chapter on virtual memory discusses this. Each process can have + up to NSEG segments, and at this line, newproc is clearing all + the pointers to the NSEG segments. + proc.c:340 + Processes have a pid that identifies them. The pid is unique + within a node. incref takes a Ref structure, that contains a + counter, and increments it. The author uses incref and not ++ + because some other processor might be creating a process--well, + not now. incref uses locks to avoid races. So, in this line, a + new pid has been allocated. It is ``1'' because pidalloc was + initialized to zero early during kernel bootstrap. + proc.c:341 + noteid identifies a ``process note group''. Processes may be + posted notes, which are kind of UNIX signals. Notes are + strings, though--and may be posted through the network using + proc(3)! The system itself posts notes to processes when they + get an exception, and they can prepare to handle the note as + said in notify(2). You can post a note to a group of processes + (a set of processes with the same noteid), and all processes + with that noteid will get the note. A new note group has been + allocated. + proc.c:342,343 + If so many processes have been created that pidalloc or + noteidalloc get wrapped down to zero (by a set of increments), + panic. + proc.c:344,345 + If there is no kernel stack for the process (which is the case) + a new stack is allocated. Remember that smalloc keeps on trying + until the stack can be allocated. Right now the kernel is + running into a rather borrowed kernel stack. The current stack + belongs to the current processor, not to the current process, + and each process should have its own kernel stack where the + hardware will push the processor context on traps and + interrupts, and where kernel procedures will be called during + system calls made by the process. + The author tries not to waste time by keeping the kernel stack + for a process that existed before; its kstack would be non-nil + and the one used in the previous life of its Proc would be + reused for the new process. + proc.c:347 + All set. If you take a look to it all, the author has + initialized everything to just nothing--except for the kernel + stack, which comes along with the allocated Proc. The process + must now be given some resources to start working. + + main + userinit + + ../pc/main.c:237 + Back to userinit in main, it starts to give resources to the + process. At this line, create a new namespace pgrp. + newpgrp()Allocate a new process group + ../port/pgrp.c:43,51 + newpgrp simply allocates a Pgrp structure with everything set + to null. It also allocates a new process group id for the just + created group and sets ref to 1. + portdat.h:49,53 + Perhaps it's time to say a bit about Refs. a Ref structure + contains a lock and a counter. It is used to do reference + counting--hence the name--although it seems to be reused to + allocate pids, etc. too. A reference counter (Ref) is simply a + counter with an integer value that corresponds to the number of + users (i.e. references) of the data structure the counter is + associated with. For example, the Pgrp just allocated is used + only by the process being initialized. Therefore, the counter + must be one. Whenever a new user of the referenced structure + appears (e.g. a new process starts sharing our Pgrp), the Ref + is incremented. When a user disappears (e.g. a process using + the Pgrp ceases to exist) the counter is decremented. If the + counter ever reaches zero, the data structure is no longer used + and can be deallocated. The Lock is necessary because multiple + processes (and processors) could be updating the counter at the + same time. You might say that it would have been better to + implement reference counters by atomic increments and + decrements on word-sized values as the Linux kernel and some + others do. However, the Plan 9 approach has two advantages: it + is portable and simple to understand. By not optimizing what + does not need to be optimized, the machine dependent part can + be kept small, and the code can be kept more + understandable--ever looked inside of the Linux kernel? give it + a try. + + Lesson: Do not optimize; ever. Do optimize only when you really + have a performance problem. And be very reticent regarding what is + a performance problem: processors are increasing speed + dramatically. + Another reason I did not say is that the ``atomic increment'' + done by Linux is not so atomic--not a single instruction; at + least not in all the cases and for all the architectures. + ../pc/main.c:238,239 + The Egrp (environment variables) is also allocated--initialized + to zero, and its reference counter set to one. It puzzles me + why there is no newegrp routine. Admittedly newpgrp assigns an + id, but it is definitely not more complex than it would be + ``newegrp''. + main.c:240 + dupfgrp (which duplicates an Fgrp) is called with a null value + to create a new file descriptor group for the process. Again, + maybe a newfgrp routine would avoid surprises for the reader, + although the code is pretty clean and the author knows the good + reason that newfgrp does not exist. + dupfgrp()Create/duplicate a file descriptor group + ../port/pgrp.c:170,183 + First, a new Fgrp is allocated and if no Fgrp to duplicate was + given, the Fgrp is initialized by allocating a chunk of + entries. The DELTAFD name suggests that the fd array is resized + on demand to contain DELTAFD extra entries. That is in fact the + case. It is a usual technique employed to avoid fragmentation + and save time to extend arrays dynamically with ``delta'' new + entries every time they run out of entries--instead of + allocating a rather big array or refusing to admit more + entries, or allocating one extra entry at a time. + It returns with a brand new file descriptor group with no open + file (no channel linked into) and DELTAFD ready entries. The + reference counter is again 1. + ../pc/main.c:241 + newrgrp creates a new rendezvous group for the process. + newrgrp()Create a redezvous group + ../port/pgrp.c:53,61 + Again, this just allocates the Rgrp and sets the reference + counter to 1. + ../pc/main.c:242 + procmode is set to 640 (octal). Processes are handled by + files--like everything else. devproc implements the driver + supplying /proc files, that represent processes. This field is + simply the permissions for the process, in the file system + view. Using a file for everything is a nice way of fixing how + permissions are checked: in the same way file systems check + permissions on real files. + Although processes are files, there is no way to create new + processes by using file system operations. The author + considered that it wouldn't pay the effort, which is reasonable + since processes are created locally, within the same node. The + same happens to several other system calls that cannot be + performed using the file system. + main.c:244 + text contains the name of the file where the process text + (code) comes from. In this case the author uses the string + *init* because there is no file. + main.c:245 + Positive discrimination at work. eve is the name of the user + who boots the machine. Well, eve is the name of the array in + ../port/auth.c:37 that holds the name of the user who boots the + machine. Conventionally, in Plan 9, that user is referred to as + ``eve''. You know, ``Adam and Eve''. In Plan 9 there is no + ``root'' (superuser), but ``eve'' is given more privileges than + other users. The first process certainly runs on the name of + the user who booted the machine, hence this line. + main.c:246 + Ok, the kernel did that before. But the code is cool, isn't it? + fpoff()Places the FPU into an ``inactive'' state + main.c:247 + This executes some instructions to place the coproprocessor in + an ``inactive'' state. FPOFF is defined at l.s:373,378. By the + way, this and the previous line should be replaced by a call to + procsetup (main.c:564,569). + +Hand-crafting the first process: The state + + main + userinit + + main.c:250,256 + Preparing to switch to the first process. sched is a member of + Proc of type Label. A Label is like an oversimplification of a + jumpbuf in C. It is buffer where a copy of a program counter + and stack pointer is kept. Labels are used to implement + coroutines. More soon. + main.c:255 + The program counter registered in sched is the address of the + init0 routine. That function will be the very first thing + executed by the process being created and its purpose is to do + some final arrangements before jumping into the user program + for the process. + main.c:256 + The stack pointer saved in sched is the address of the + allocated kernel stack (kstack) plus the size of the allocated + stack minus something. On the Intel, stacks grow downwards; to + lower addresses. The address of the allocated stack is the + lowest address in the stack, but the stack pointer for the + empty stack would point to the biggest address of the allocated + stack on an Intel. The ``minus something'' thing is to reserve + some space at the bottom of the stack. What's the reservation + for? + ../port/portdat.h:91 + MAXSYSARG is the maximum number of arguments for a system call. + Here, the assumption is that each argument occupies at most a + word (if it occupies more a pointer would be used). + ../pc/main.c:256 + The number of words for arguments is multiplied by the number + of bytes in a word, because adding to kstack makes it move + counting characters, not words. By the way, the ``-12'' in the + comment seems to be a relic: 5 words times 4 bytes per word is + 20. I guess at some point there was a kstack-(12+something) and + the 12 was removed and the comment kept obsolete. But who + knows. + Taking into account that the reservation is for system call + arguments, for me it looks like the author wanted to ensure + that the (theoretically) pushed arguments for a system call + made within the kernel always are valid memory. There is a + check in trap.c:504 that precisely ensures that. For a kernel + process, the arguments would not stand in the ``user stack'', + but in the kernel stack instead. + What is needed is a kernel stack that has a fake return PC on + it so that gotolabel could overwrite it to ``return'' to the PC + in the label. But I am not sure more extra room be needed. + + NOTE: Is this ok? + main.c:261 + The first segment for the new process! (Not to be confused with + a hardware segment) It is going to be an STACK segment. Must + start at USTKTOP (initial top of user stack) minus USTKSIZE + (the size of the stack: it grows downwards!). The number of + pages in the segment must be the number of pages to get + USTKSIZE bytes. Forget a bit about how is the segment created + by now. But think that the Segment structure is created and it + contains in the end a bunch of (indirect) references to Page + structures. By now all the pointers to Pages are null. Note + that addresses mentioned here are virtual addresses. + The virtual memory for this process will look like the one + depicted in figure [189]3.7 (in that figure you can see the + virtual memory for a second process too, so you could get the + feeling of how this works). Right now the kernel is running on + the stack near the Mach structure; although it will later run + at the kernel stack for the process being created. + + CAPTION: Figure 3.7: Virtual memory for user processes. Permissions in + the hardware page tables will be set so that user code (ring 3) is + unable to access the last two gigabytes of the virtual address space. + + \resizebox{14cm}{!}{\includegraphics{vmem.eps}} + + main.c:262 + The stack segment is placed into the seg array for the process. + The stack segment always resides in the SSEG entry. + main.c:263 + Got the segment, but it has no memory. The call to newpage + obtains a new fresh page; later segpage plugs the page into the + segment. The page is requested to be cleared (the ``1'' for + newpage). UTKSTOP-BY2PG is the virtual address for the page. + The ``0'' for newpage is a pointer to the Segment reference and + we are not (yet) interested what that is for. Ignore how + newpage works by now, but take into account that a page is + allocated from the page (frame) allocator, its reference count + gets incremented, its referenced/modified field (modref) is + cleared, and its virtual address (va) is set to the one given + to newpage. + main.c:264 + segpage attaches the Page into the segment at the virtual + address specified by the va field in the page. One of the + pointers of the Segment points now to the page. The segment has + memory! And the user has an initial stack to issue procedure + calls on it. + One thing to note is that the MMU knows nothing about this page + yet. Only the kernel data structures know that the segment has + a page there. The MMU page table will be updated when the page + is first used. + main.c:265 + The page is ``mapped'' for the segment, but we are running in + kernel now, and not even within the context of the process + holding the segment (i.e. not using its address space). kmap + maps the page for the kernel and returns the address the kernel + should use to access the page. + dat.h:202 + Nice. kmap only has to add KZERO to the physical page address. + Remember that the kernel did set up a one-to-one mapping for + physical memory at address KZERO? That's why. No need to add + temporary entries to the current page table just to access + physical memory. But, why is kmap named ``map''? It is + conceptually mapping the page for kernel usage. It doesn't + matter if all the feasible maps were done before. The use of + kmap instead of just ORing KZERO also allows the author to + change his mind and use another implementation in the future + without changing the code that depends on kmap. Interfaces are + important in that they isolate pieces of code. + + Lesson: Keep clean interfaces between different components of your + programs. Interfaces allow you to modify one component without + affecting the others. + main.c:266 + VA gives the (user) virtual address for a given kernel address, + and bootargs places arguments for the initial process in the + page whose virtual address was given. By convention, Plan 9 + processes receive two arguments for their main program, the + argument count, and the array of arguments. Each argument is + just a string. And by convention, the argument zero is the + program name. See exec(2). + By using arguments and environment variables, users can control + what the executed program will do. + dat.h:201 + Because on PCs, the kernel shares the virtual address space of + the process running, VA simply returns its argument. + + NOTE: Not sure at all about my assumption about what VA is and why + it does return its argument + . + + main + userinit + bootargs() Sets up arguments for the first user process. + + main.c:305 + bootargs is building arguments for the user process entry point + in the user stack. sp is set to the top of the (empty) user + stack. Again, space is reserved for MAXSYSARG words. + main.c:307 + ac is the argument count. zero by now. + main.c:308 + first argument. av is the argument vector (i.e. like argv) and + its first entry points to the string ``/386/9dos'' just pushed + on the user stack by pusharg. The first argument is the program + name. In this case, it is customary that the program be called + 9dos, the Plan 9 version for PCs. + pusharg()Pushes an argument in the user stack. + main.c:286,294 + pusharg only advances the stack pointer to make room for the + string given, and copies it there. It returns the new stack + pointer (which points to the first character in the pushed + string). + main.c:309 + cp was set to point to the address where the kernel loader + placed the bootline. Ensure that it is null-terminated. + main.c:310 + In buf, the author is going to adjust bootline. The adjusted + version will be pushed as an argument. The 64 in the + declaration should probably be replaced by BOOTLINELEN. + main.c:311,318 + If bootline started with fd, place the canonical full name for + that: ``local!#f/fd0disk''. That saves typing for the boot user + and keeps the first process happy. The ``#f'' is the path to + the kernel floppy device. The name is pushed on the user stack + and placed into the argument vector. + main.c:314,316 + The same for hard disks. + main.c:317,318 + If option ``n'' is given to the first process, it understands + we are booting from the network. Surprisingly, option ``n'' is + missing from the boot(8) manual page (boot is the first + process). + main.c:319,324 + If the argument was a floppy or a hard disk, put the name of + the disk into the conf structure as if the user said + bootdisk=... in plan9.ini. + main.c:328 + The stack pointer points to words, but pusharg puts characters + in the stack. This is ensuring that dummy bytes are pushed on + the stack in case that is needed to complete a word. But all + the arguments are now pushed. + main.c:331 + Make room in the stack to put the argument vector--with + pointers to the arguments just pushed. The +1 is because it has + to be null-terminated (did you read exec(2)?). + main.c:332,335 + lsp is the argument vector passed to the user program. It is + built by pushing in the stack each of the recorded arguments in + av and null-terminating it. av[i] was the kernel virtual + address for the pushed argument. The added expression is to + ``move'' that address into the one seen by the process. It is a + translation. The length of the translation is the difference + between what the user code thinks is the start of the page + allocated for the stack, and what the kernel thinks is the + start of that page. This addition is necessary: remember that + the kernel is using a virtual address that depends on the KZERO + mapping for the stack (e.g. bigger than KZERO), but the user + will use its own user virtual address for the stack (e.g. lower + than KZERO). The KZERO map has no permissions to be used by + code running at ring 3. Otherwise, a user program would be able + to access all physical memory installed. + Perhaps the usage of a ``kernel-virtual-to-user-virtual'' or + ``kv2uv'' macro would make this more evident. + main.c:336 + The same adjustment has to be done to the stack pointer itself. + Beware, I did not tell, but sp is a global variable pointing to + the user stack for the boot process. That is why it is adjusted + and the routine just returns. It is probably a global because + init0 is the one using sp to jump into the user code. Because + we are going to loose our stack when jumping to init0 later, + the author cannot easily pass the argument using the kernel + stack of the new process. The sizeof ulong adjustment is for + the argument count. By the way, what happened to the argument + count? Does boot not use it and nobody noticed? Or are we + missing something? + + main + userinit + + main.c:267 + The user stack is all set. So release the kernel map for the + stack page; i.e. do nothing. + main.c:272 + A segment of type TEXT is created for the process. It starts at + UTZERO (the zero address within the text segment). Just one + page suffices (that's 4K). + main.c:273 + flushme has to do with caching. Forget it. + main.c:274,277 + The segment is placed in the list of segments for the process + (slot TSEG for the text segment). A page allocated at address + UTZERO and linked into the segment as before. Ignore the + memset; it is honoring flushme. + main.c:278,280 + The text segment for the process is initialized with the + contents of initcode. That is the program run by this process. + If you look into ../pc/initcode you'll see that it simply execs + boot. + Hint: You run new programs in new processes by doing a fork and + then an exec. By hand-crafting the first user process, the + system is doing the fork (It cannot use fork because there is + no process to fork). The best way to avoid hand-crafting an + exec is to use a silly user program that calls the regular exec + system call. You're done, and you can start as the first + process any program you want! + main.c:282 + ready changes the process state to Ready (ready to execute) and + links the Proc into the scheduler ready queue--the queue of + processes ready to run. More on that later. + +Starting the process + + main.c:164 + userinit is done, and schedinit starts up the scheduler now + that there is a process to schedule. schedinit never returns, + so main is really done. + + main + schedinit() Initialize and start scheduling. + + ../port/proc.c:57 + m points to the Mach structure for the current processor. In + ../pc/dat.h:160 you can see how it contains a Label (you know, + PC and SP buffer). setlabel()Record PC and SP. + ../pc/l.s:497,498 + setlabel receives a pointer to a Label. It first loads ax with + the pointer to the label passed. FP is the ``frame pointer'' + that points to the activation record for setlabel in the stack. + l.s:499 + the current stack pointer is copied into label[0] (considering + label as an array of integers now). + l.s:500,501 + The stack has the typical layout for a function call. The + function right now is setlabel. The top of the stack contains + the ``return pc'', i.e. the address where to continue executing + upon return from setlabel. That address is stored in BX, and + then BX is placed into frame[1] (considering label as an array + of integers now, assembly uses offset 4 because an integer has + 4 bytes). The return PC points to the instruction in schedinit + right after the call to setlabel. + So, m->sched has the PC and SP corresponding to the point of + execution right after setlabel was called. + ../port/proc.c:58 + up is a pointer to the current user process. Right now, it has + a null value. So, why does schedinit check for up? You will + know in the next chapter; You are not expected to, but can you + guess why? + It is obvious that up cannot be a global variable, because, how + could then different processors have different user processes? + up is defined at ../pc/dat.h:263 to be the externup field of + the Mach structure for the current processor. For each + processor, that field points to its current process. On + uniprocessors, a global up would suffice. + proc.c:83 + The scheduler is called. sched picks up a process and switches + to it. Right now there is only a first (boot) process. + + main + schedinit + sched() Schedule a process. + + proc.c:93 + If up is not null, there is a current process and the routine + must save its state; otherwise the kernel won't be able to come + back to the process when it be allowed to run again. But there + is no current process yet; forget this now. + proc.c:107 + runproc chooses among the set of ready processes one to be run. + up is set to point to it. Until the next time sched runs it + will be the current process (for this processor). + + main... + sched + runproc() Elect a process to run. + + proc.c:201 + Interrupts allowed. From now on, the timer, and any device can + request our attention. Interrupts will be serviced using the + kernel stack of the boot processor, by now. + proc.c:202,203 + idlehands does whatever the kernel should be doing while there + is nothing to run on the processor. It is defined as ``do + nothing'' at ../pc/fns.h:43. So, whenever no process is ready + to execute the kernel would be looping here doing nothing until + an interrupt (or another processor) changes things. + proc.c:204,243 + The loop keeps on looping until a process is found for running. + Whenever it gets that process, it jumps to the found label, + where the fortunate process will be put on the processor. The + only thing to notice right now is that there is an initial + process and the jump to found is done. Although it is also + interesting that the loops leaves rq pointing to the run queue + where the selected process resides. There are several run + queues as we will see in the next chapter. + proc.c:246 + Interrupts cleared: The routine is messing up with the queue of + ready processes, if an interrupt arrived and could change + things, the kernel could crash. + proc.c:247,248 + What if another processor is also picking up a process to run? + The routine should wait until that processor be done with the + scheduler queue. So, if it cannot gain the lock of the run + queue, it goes back to the loop. Interrupts were disabled + before locking the queue, but that affects just to the + processor running this code, other processors are free-running. + The goto will again enable interrupts and reenter the idle loop + that searches for ready processes. The routine will again + detect that a process can be run, and try to lock again the + scheduler queue (the process that it found before the goto loop + might still be there if not picked up by another processor). + This is busy waiting (i.e. no semaphores), but since the + routine cannot even know who should run, what else can it do? + You might say that the author could let the old current process + run a bit more time, but it could be that 1) there is no such + process or 2) such process is now blocked waiting for something + to happen. + This is not the case now. There is one process (boot) for us to + run. + proc.c:250,255 + Got the lock, now search for a process p that runs at this + processor (affinity!). head is the head of the processor ready + queue and the rnext field of Proc is used to link processes + into this queue. The loop selects any process p that either + 1. + did run in the processor running runproc, for affinity. + The routine can know that because the mp field of Proc has + the number of the field machno in the Mach structure where + it did run last. + 2. + did not move recently (to avoid trashing, i.e. moving a + process repeatedly between several processors). The code + knows that p did not move recently because in movetime p + has the earliest time when it is allowed to move; more + below. + l points to the Proc right before p in the run queue. + For us, p points to the ``*init*'' process just created by + main. + proc.c:260,263 + If the run queue is empty, go back to the loop. It could be + empty because all processes can be blocked (not the case). It + also goes back to the loop when the process is running on a + different processor (the process state is at the processor, and + not saved within the kernel; see the comment to learn how to + know that). + proc.c:264,271 + Note how easily the process is removed from the run queue. It + is no longer ready, it is going to be running. The counters for + the number of processes in the run queue and the number of + ready processes are updated. + proc.c:272,273 + This should not happen. The kernel (as any program) tries not + to flood the user with messages. Whenever something important + has to be said, it does so; otherwise it remains silent, + because, who cares? Guess why this shouldn't happen? + proc.c:274 + Done with the run queue, let other processors use it. + proc.c:276 + The process is being handled by the scheduler. Perhaps this + could be moved right before line :274, to make sure that if by + any bug, the process gets linked back to a run queue, everybody + will see that it is scheding and report the bug in line :273. + proc.c:277,279 + Must honor conventions. mp must have the number of the Mach + (processor) where the process last run on. mach, the pointer to + the structure is a different thing and may be null. Also, + movetime is set to the current time at the boot processor plus + 1/10 of second. HZ has the number of ticks per second and ticks + gets incremented every tick. The author uses the time at + processor 0, to make all processors agree on the current time + on an MP machine (every processor has its own vision of time + depending on the exact point when it was initialized). + So, p is removed from the ready queue and attached to the + processor where it is going to run (it is not going to be + ready, it is running). + + main + schedinit + sched() Schedule a process. + + proc.c:107 + Back in sched, the pointer to the current process is setup as I + said before. + proc.c:108,109 + Update the state and set the mach pointer. Its state is going + to be in the processor. Also, the proc field of m is updated. + You can go from Mach to the current Proc and vice-versa. + proc.c:111 + mmuswitch changes the address space to that of the new process. + mmuswitch()Switches the MMU to another page table. + ../pc/mmu.c:126 + This is the only line executed now, it is not really switching + the ``Intel task''. It will load the page table given: the page + table for the processor. If the process has its own page table + (lines above) that one is used instead; not the case! The + kernel stack for this process--used by interrupts and traps + that occur while running at user level--will be setup to the + top of the currently empty kernel stack of the process. kstack + points to the memory allocated for the stack but that is not + the top of the empty stack. + taskswitch()Switches the Intel idea of the current task. + mmu.c:27,40 + It is updating the TSS used by this processor to ensure that + the kernel stack pointer will be set at stack, within the + address space determined by the page table pointed to by pdb. + Besides, it loads the new page table pointer into the MMU. The + kernel has just switched to the address space of the just + created process, but it is still running using our boot + processor stack. Don't worry, the kernel is mapped the same way + at all page tables used for Plan 9 processes, so our (kernel) + virtual addresses keep on pointing to the same place in memory. + The chapter on virtual memory will make this more clear. + ../port/proc.c:112 + Our mind is going. Remember that sched was setup to have the PC + for init0 and the SP pointing to the end of init0's parameters + pushed manually by main. + gotolabel()Jumps to a saved context + ../pc/l.s:489,490 + gotolabel resets the stack and program counter with those of + label. It now fetches the pointer to the label into a AX. We + consider label as an array of int, although it is not. + l.s:491 + The stack pointer is set to that in label[0], the old boot + processor stack is gone. At this point the processor starts + using the kernel stack for the new process. + l.s:492,493 + The trick!, when gotolabel returns, the machine jumps to the + return PC (theoretically) pushed last on the stack by a call + instruction. By pushing the PC saved in label[1] (i.e. the + start of init0 code), the ret at line :495 ``returns'' to the + PC in the label. + l.s:494 + The convention is that functions returning an int use register + ax to pass the value back to the caller. Usually, the 1 just + returned will appear to be the return value of setlabel, but + that is explained in the next chapter. + + init0() (Kernel) entry point for the first process. + + main.c:190 + We are running at the address space of *init*, using its kernel + stack, and starting at the first instruction of init0. Now we + are a regular process executing within the kernel. Not just the + flow of control taken after the machine was reset. + main.c:197 + Interrupts were disabled during the context switch, but now the + kernel can handle them again. + main.c:199,206 + The comment states that chandevinit will not call any + rootinit--there is none. Remember chandevreset? The same thing + again. The comment regarding early kernel processes means this: + you do not have root and current directories for this process, + and although you want to setup such things for the user code + about to run, it is good to setup them now so that kernel + processes started before jumping to user code could at least + have silly root and dot directories, provided by the root + device. I don't know why there is no rootinit function with + this code in, the author knows. + main.c:203 + slash is a pointer to a Chan structure for the root directory. + It is set to point to a channel given by namec (``name + channel''), which corresponds to a file with the given name in + the current name space. What? I said namespace and there is no + root yet? Yes. Plan 9 have absolute paths, relative paths, and + paths for kernel device files. ``#/'' refers to the root of the + file tree serviced by the root device. Devices service file + systems named by ``#character''. ``/'' is the character for the + root device. The reason to have device paths is that no matter + how many adjustments a process makes in its name space, it + still has access to kernel devices and can access system + provided files--this is not the whole truth. + So now slash points to the directory serviced by root--which is + the root of root's file tree. You will see how this happens in + the chapter devoted to files. But you already got a glance + about it when we discussed channels and root. Try to read the + code anyway. + main.c:204,205 + cnameclose simply removes the given name--not the whole truth. + Right now, it is ``#/'', and that's a funny name for our /. So + the author creates a new name for the channel. What? channels + have names? Yes they do. Think that they are caching the file + name. + main.c:206 + cclone clones (dups) a channel. Now dot ``points'' to the file + where slash points. + main.c:208 + chandevinit calls the init routine for every Dev configured in + devtab. We are now a regular process, have a regular + (reasonably sized) kernel stack, are handling interrupts once + in a while, and devices can be initialized. I are not going to + describe how the various init functions work. Only when they be + relevant for the topic of one of the given chapters I'll do so. + main.c:210,223 + Various environment variables are set up for the current + process. The lines for setting the terminal environment + variable are generating a suitable value from the current + architecture name. The kind of cpu is set to 386, you know + that, right?. This is very important, because $cputype is used + among other things to choose what binaries are appropriate for + this architecture (saw /386 on your Plan 9 box?). The + environment variable service is also important, because boot + uses it to choose the rc script used to start system services. + On terminals you want rio, on cpu servers you probably don't. + For configuration (ini) parameters with names not starting with + *, the author sets environment variables to reflect their + settings. This is very important, because if the boot initial + program is ever updated to take into account some peculiarity + of the Plan 9 installation, an environment variable can be used + to indicate that; just by adding a line to the plan9.ini file. + Ignore the waserror and the poperror. They are described in the + next chapter. + main.c:224 + A kernel process is created named ``alarm''. It will start + executing at the kernel function alarmkproc. That function + iterates through the list of alarms searching for expired + alarms. Then it posts ``alarm'' notes to the processes with + expired alarms and sleeps until the next alarm expires. This is + really good because it turns alarm handling into a sequential + activity: not all processes must be setting up timers for + pending alarms while in the kernel. But we are not interested + on that now. + main.c:225 + touser transfers control to the user program within the given + process context. The global variable sp is used to tell touser + what should be the current user stack pointer. This was + initialized before by bootargs. + + init0() + touser() Perform an upcall from the kernel to the user code. + + plan9l.s:12,25 + The trick is to pretend that we return from an interrupt + suffered while running the user program. The processor is silly + and obeys, reloading the processor context with that of the + ``previously'' running user program. + plan9l.s:13,19 + All these pushes are building the fake stack frame after the + (not-existent) interrupt: User PC, user code segment, user + flags, user stack pointer, user stack segment. The code and + stack segments are the UDSEL and UESEL, which are the + appropriate selectors for UDSEG and UESEG. + plan9l.s:16,17 + A fake flags word with just the interrupt enable bit set is + pushed on the stack (as if it was a real flags pushed during + the interrupt that saved the frame being built). After the + iret, we are sure that interrupts will be enabled. It would be + a disaster if that was not the case, because no timer could + ever preempt the process. + mem.h:75,76 + Users run at ring 3, with non-privileged mode. Interrupts and + traps lead to a switch back to kernel mode as dictated by the + IDT entries. + plan9l.s:20,24 + The user data segment descriptor is copied into the descriptors + for all other user's extra segments. These are not loaded by + the iret, so they are updated by hand. + plan9l.s:25 + Up to userland. After this instruction, the program in initcode + is running at user-level, with the kernel fully initialized + below to handle traps and interrupts. + initcode:14 + When the program reaches this point, a trap is raised with + number 0x64, and the exec system call to execute the program in + /boot is issued, with arguments for /boot taken verbatim as + given to us. Remaining initialization is up to boot! + + Now, go read again boot(8) and take a look at what it does. That is so + clearly stated there that I'd rather interfere your learning by + repeating it here. + + One final consideration. Most of the work done by userinit in main + would be portable and could be said to belong to the port directory. + However, some machine dependent assumptions (e.g. the growing + direction of stacks) are being made. The code is more simple having a + single userinit than it would be having a machine independent userinit + and then a machine dependent userinit with the code that cannot be + made portable. Portability refers to the difficulty of porting the + code to a new system, not to the number of lines of the pc directory. + If the pc directory holds more files, but is easier to understand, and + easier to rewrite/adapt for a new architecture; that's fine! + + So you now know how the kernel boots, you have an operational system + and everything else is done by issuing system calls to the kernel. In + the following chapters we will read the code related to servicing + system calls for the major components in the system. + + Processes + + On this chapter, we will read the code related to processes. As I will + do with following chapters too, I try to follow the execution path for + system calls related to the chapter topic; but I make exceptions to + this discussion order whenever I feel its necessary. + + Although I am not discussing source code files, one file at a time, I + suggest you still try to read files as they appear. The worst thing + that can happen is that you don't understand the code and come back to + the commentary; but another thing that can happen is that you + understand most of it or it all on your own! That would be a big + progress! During this chapter, you will be reading these files: + * Files at /sys/src/9/port: + + portdat.h + Portable data structures. + + portfns.h + Portable functions. + + proc.c + Processes. + + pgrp.c + Process groups. + + devcons.c + Console device. + + devproc.c + Process device. + + alarm.c + Alarm handling. + + tod.c + Time of day. + + taslock.c + Test and set locks. + + qlock.c + Queuing locks. + + sysproc.c + Process system calls. + + * Files at /sys/src/9/pc: + + trap.c + Trap handling procedures. + + dat.h + Machine dependent data structures. + + fns.h + Machine dependent functions. + + clock.c + Clock handling. + + main.c + Machine dependent process handling. + + l.s + coroutines, locking and other low-level routines. + + ...and several other ones used as examples. + + Trap handling continued + + Before looking at how processes work, let's revisit trap handling once + more. I will be using the clock interrupt as an example of the trap + source. The clock interrupt is important because it is the mechanism + used to multiplex the processor among processes. In what follows, + assume that a user process was running while a clock interrupt happen. + + trap() C entry point for traps. + + /sys/src/9/pc/trap.c:218 + l.s dispatches the interrupt to the trap procedure, supplying a + pointer to the Ureg structure. + trap.c:225 + intrts is set to the result of fastticks. This Mach field + records the time stamp for the interrupt. That is necessary for + devintrts that handles interrupt time stamps. + devarch.c:597,601 + The time stamp is the result of the architecture specific + fastclock routine, which is defined to be cycletimer + devarch.c:586,595 + that returns the time stamp counter of the processor. (In case + you don't know, Intel processors from the Pentium up have a tsc + register which is incremented by the hardware at every clock + tick). + trap.c:226,230 + user is set to true if the interrupt (or trap) happened while + running user code. It was so, if the saved code segment within + the Ureg is the user code segment. + trap.c:232 + The trap number is kept in vno (vector number). It is going to + be used heavily and caching it in a variable will both enhance + the readability of the code and make it run faster. + What can be the value of vno? + trap.c:175,208 + excname contains names for the first 32 trap numbers, which are + generated by the processor. If vno is less than 32, it must be + an exception generated by the processor. See figure [190]4.1 if + you got lost. + + CAPTION: Figure 4.1: External interrupts (from the PICs) are + dispatched by IDT entries at VectorPIC; processor exceptions (caused + by a faulting instruction) are dispatched by the first 32 IDT entries; + other exceptions can be ``called'' by int instructions. In the end, + either trap or syscall service them. + + \resizebox{14cm}{!}{\includegraphics{traps.eps}} + + Otherwise, vno is either within VectorPIC (32!) and + VectorPIC+16, or it is above VectorPIC+16. In the first case, + the event corresponds to an external interrupt routed through + the PIC; in the second case, it must be a ``software generated + interrupt'' (i.e. int n). + trap.c:233 + Back to the trap routine, ctl is the vector control structure + for this trap. If there was no Vctl, we are in trouble: only + traps and interrupts that the kernel is prepared to service had + their Vctl set up by either intrenable or trapenable. Ah, and + beware of the assignment! + trap.c:234,266 + The kernel is handling a trap or interrupt that someone enabled + before. Things go well... + trap.c:234,238 + Only for interrupts, increment the number of interrupts + recorded in the Mach structure. And if the trap number is a + ``real interrupt'' (not a processor exception, and not a system + call), take the interrupt number from the Vctl. lastintr holds + the value of the last interrupt. That is used for debugging. + Perhaps a local variable would suffice at the expense of + reporting unwanted interrupts only when they happen--see below. + + NOTE: is this ok? + The check against VectorSYSCALL seems to be unnecessary, since + the trap for system calls is routed through plan9l.s to enter + syscall (below in trap.c) directly. + trap.c:240,241 + isr is the interrupt service routine. If the Vctl has one, call + it with the trap number. But, what is an ISR? + i8259.c:159,162 + Our PIC is the i8259. When we did enable it, the i8259elcr + (edge/level control register) had one bit set per edge + triggered interrupt. The i8259isr interrupt service procedure + was set as the service procedure for level triggered + interrupts, and it was set as the end of interrupt procedure + for edge triggered interrupts. Note how fields eoi and isr are + used to turn Vctl into a programmable interrupt handler. + i8259isr()Interrupt service routine for the 8259. + i8259.c:105,128 + All i8259isr does, is to tell the i8259 that the interrupt has + been serviced by acknowledging the interrupt. The chip now + knows that, and forgets about the interrupt until it is raised + again. If the interrupt is not acknowledged, the i8259 would + ignore that interrupt when raised again, because it would + assume that the processor is still handling the previous one + and is not prepared for servicing it again. The real interrupt + number is not the one coming in vno. vno was set to + VectorPIC+number because PIC serviced interrupts start at + VectorPIC in the IDT. By adjusting the number, irq contains the + interrupt number that the i8259 knows about: from 0 to 15. + trap.c:242,245 + Here is where the functions registered as interrupt handlers + (or trap handlers) are called. For the clock interrupt, the + handler will be clockintr, as said in i8253.c:130 by + i8253enable. Let's defer a bit what clockintr does, but note + how this is the point where the trap (or interrupt) is actually + serviced. Vctls for the same trap are linked through the next + field--there can be several handlers for the same interrupt. + The check in line :243 shows that a vector number can be + enabled (the kernel knows it is ok to get that trap) even when + there is nothing to do to handle it. + trap.c:246,247 + You now know what this does. When necessary, it calls the ``end + of interrupt'' routine. + trap.c:250,265 + The author preempts processes here. This is discussed in the + next section. + trap.c:267,271 + There is no vctl for the trap number: no part of the kernel + requested to handle it. Besides, the trap number has a name in + excname, and the trap comes from the user program. The user did + something weird and got a trap generated by the processor. + After indexing with the number to get a name for the trap, a + note for the trap is posted to the process. The process is + likely to die. Interrupts (disabled since the trap) are enabled + before posting the note. + You can get into these lines when any of the bad things named + in the excname array happen to the process. + trap.c:272,294 + Not a ``handled'' interrupt, and not a processor exception + while running user code. The condition checks that vno + corresponds to an interrupt and not to a processor exception. + Again, is the check for VectorSYSCALL necessary? + In this case, the number of spurious interrupts for the + processor is incremented and trap returns doing nothing more. A + message is printed because this shouldn't happen. Now that we + bothered the user, the for loop also reports other unwanted + interrupts at different processors. If you read the comment, + you see that the author is suspicious of IRQ 7. Most PCs keep + on delivering that interrupt under certain circumstances even + if you are not allowing interrupts. + trap.c:295,308 + Really into trouble. It must be a processor exception while + running kernel code. So the kernel has a serious bug. The + dumpregs call prints processor registers to aid in debugging + the kernel, and then the kernel calls panic. Only the boot + processor (machno zero) panics, other processors sit in a loop + until the panic at the boot processor causes the system to go + down. + trap.c:310,313 + If something was posted for the process, honor it. More on that + when we read note-handling code. When trap returns, l.s will + reload the processor context from the Ureg and it will resume + the activity previous to the trap. + panic()Issue a message and halt. + ../port/devcons.c:183,204 + Just to satisfy your curiousity, panic prints the given message + (dumps the stack to aid in debugging the kernel) and halts the + system by calling exit. + exit()Stop system operation. + ../pc/main.c:606,630 + exit prints the ``exiting'' message once for each processor + (note the use of the active.machs bit field. Then it waits for + a while to let the console print the panic and exiting message + (important if going through the serial line). Finally, if + running at the boot processor on a terminal, it loops forever. + For CPU servers, seems like a reboot (reset) is preferred to + restart CPU server operation--after giving some time to let a + human read the message. The exiting field of active is set to + true. + As each processor exits, its bit in active.matchs is cleared, + and other processors will exit too because they notice the + active.exiting bit (see ../pc/clock.c:53,54). This is shown + later. + + System calls + + Some system services (eg. clock handling) are requested by interrupts; + some others are requested by explicit system calls. Let's complete now + the discussion of system call handling. + /sys/src/libc/9syscall/mkfile:51,61 + This script generates for all system calls listed in sys.h, a + procedure that puts the system call number into AX, issues an + int instruction, and returns. These procedures are called to + issue system calls from user code, and are linked along with + every user program. Although there are many system calls, all + of them use the same trap number, and it is the parameter in ax + that determines which one is being requested. + + syscall() C entry point for the system call trap. + + ../pc/trap.c:471 + System calls get routed to syscall in trap.c by plan9l.s. + trap.c:477,478 + If a system call was issued from the kernel something is wrong. + The saved Ureg CS selector is used to check if the system was + running at ring 3 while the system call was issued. + trap.c:480,481 + Accounting for number of system calls services, and noting that + the process is servicing a system call. + trap.c:483 + registers for the user program are those saved in the Ureg. The + name is dbgreg because this is very useful for debuggers, to + fix up a faulting program and let it continue. The last known + PC for the process is that saved in the Ureg; remember that in + the Proc. + trap.c:485 + This line recovers the system call number from the ax register + from the saved user context. + trap.c:487,490 + Coprocessor stuff. If doing a fork (to create a new process) + and the coprocessor was used, save its state in the fpsave for + the current process. The new FPU state is inactive. By doing + this, the author ensures that both the parent and the child + process start with an PFinactive coprocessor state. The child + may not use the floating point unit, ever; in that case, its + FPU would be kept FPinactive. + trap.c:491 + System call servicing may take some time; enable interrupts. + All the information needed now is kept in up (and ureg). If an + interrupt arrives, the current (kernel) stack will be used to + service it and the current processing will continue after + returning from that interrupt. + trap.c:497,502 + (Ignore the error handling; just assume that line :497 is + entered). If the number is not that of an existing system call + (between 0 and nsyscall-1), post a note for the process and + report the error. As you will see, error would cause the + routine to continue at line :513 in this case. + trap.c:504,505 + When the stack pointer for the user code (sp) is not in the + first page mapped for the stack, or is so near the top of an + empty stack that it seems to be no space for the system call + arguments, check that the addresses going from sp to the end of + the system call arguments are indeed okay. The first stack page + is known to be okay because the kernel mapped it when the + process was brought to life; but we cannot be sure otherwise + that the user stack pointer looks fine and points into existing + stack space. The kernel checks before accessing the user stack. + + Lesson: Don't trust your users! If you implement any kind of + service, assume that users would be as malicious as you can image. + Usually, they will not be malicious, but they will have bugs that + could make them behave as if they were really malicious. + trap.c:507 + s in the Proc structure is set with the arguments for the + current system call. s is of type Sargs, which holds as many + words as MAXSYSARG says--i.e. as many arguments as a system + call may take. The word in the top of the user stack is + ignored; that would be the return PC for the ``system call'' + assembler routine called by the user code. + trap.c:508 + The string with the ``ps'' state of the process is updated to + contain the system call name. + trap.c:510 + And the system call is called. Note how the Sargs is supplied. + Arguments reside within kernel memory and can be used at will, + without checking that the stack addresses are still valid. + While the system call is executing, the kernel could switch to + a different process. + trap.c:530,538 + The result of the system call is placed into AX (will be + returned by the assembler user-level stub); and any note posted + (will be discussed later) is handled. + + Error handling + + Errors are handled by several routines within the kernel. Error + handling also includes routines used to report errors, be they fatal + or not. See pages perror(2) and errstr(2). + +Exceptions in C + + Errors are handled using error, waserror, nexterror, and poperror. + Handled with care, these routines provide a clean and fast error + handling mechanism similar to exceptions in other languages. + + ../port/portdat.h:593,595 + Each process has an array of up to NERR Labels for error + handling together with the number of entries in the array + (nerrlab). There is also a place to put an error message of up + to ERRLEN characters. + To see how this is used, let's see what syscall does for error + handling. In figure [191]4.2 you can see the whole picture. + Initially, the user calls a library function to perform a + system call, and it traps into the kernel (figure [192]4.2(a)). + ../pc/trap.c:495,496 + The return value for the system call is set to -1, which means + failure. waserror is called inside a conditional. If it returns + false, the system call will be called and return value set + accordingly; otherwise, syscall would return the error + condition. + waserror()Prepares for errors setting up an error label. + fns.h:123 + waserror increments the number of error labels for the process + (initially zero) and fills up another label in errlab + (initially the first error label). + trap.c:496 + Go back to this line. When syscall was called and it called + waserror, setlabel in fns.h:123 returns zero. The expression + (a,b) returns the value of b; therefore waserror returns zero, + which means that the then-arm of the if is taken. + During the system call the first error label is set and keeps + the SP and PC for the kernel as they were in trap.c:496 during + the early system call steps (see figure [193]4.2(b)). + poperror()Removes an error label. + trap.c:511 + The system call completed, and poperror is called. + ../port/portfns.h:199 + poperror simply decrements the number of error labels: it + removes the label added by waserror in trap.c:496. The state is + like that of figure [194]4.2(a) (of course, the PC and SP would + be that for trap.c:511), and not the ones as of line :496. + Now, imagine the system call number is wrong. + ../pc/trap.c:501 + error is called with Ebadarg to report the error. error()Raises + an error. + ../port/proc.c:1132,1138 + error copies the given string into the error string for the + process. (yes!, Ebadarg is a string with a descriptive text for + the error: portable, human readable, simple). Once the error + reason is noted, nexterror is called. nexterror()Re-raise an + error. + proc.c:1140,1144 + nexterror is where things start to move. A gotolabel jumps to + the kernel state as recorded in the last saved error label; and + the number of error labels is decremented to `pop' it off the + array. In our example, the error label was set by syscall and + both the PC and SP would be set as they were when waserror was + called. + ../pc/trap.c:496 + this time, waserror returns true, because after gotolabel, the + corresponding setlabel appears to return true. Therefore, the + conditional is not taken. In effect, nexterror is ``raising an + exception'', so that the flow of control resumes where it was + at the last waserror. Stack (local, or automatic) variables are + deallocated and function calls made since the waserror are gone + without returning. Can you see how the combination of waserror + and error forgets about an ongoing computation and resumes in + the top-level routine where an appropriate action can be taken? + In the figure [195]4.2, you can see how this works. To make it + more clear, the figure corresponds to a situation where a + system call is called ([196]4.2(a)), waserror in syscall sets + the error label ([197]4.2(b)), another kernel procedure + (syssleep) is called ([198]4.2(c)), and this procedure calls + error to raise an error ([199]4.2(d)). Noticed how it works? + + CAPTION: Figure 4.2: Error handling: labels are set in errlab and used + to raise ``exceptions''. waserror remembers the context; error + notifies an error and restores the context. + + [Initial context: The kernel starts executing a system call. PC and SP + correspond to the current kernel context.] + \resizebox{6cm}{!}{\includegraphics{err0.eps}} [Waserror is called: A + label is set to remember the context where to continue after any + error.] \resizebox{6cm}{!}{\includegraphics{err1.eps}} [More calls: + the kernel continues executing, more records pushed on the stack, + etc.] \resizebox{6cm}{!}{\includegraphics{err2.eps}} [Error called: An + error string is set, and the context is restored as it was when + waserror was called. This time, waserror returns a different value.] + \resizebox{6cm}{!}{\includegraphics{err3.eps}} + + Things are more interesting because waserror/(next)error pairs can be + nested. For example, the system call called in the previous example + could call waserror again, and a routine called by the system call + could call error. In this case, there would be two (nested!) error + labels in the error stack. The first call to error would jump to the + last label pushed by waserror; Then, a nexterror could be used to jump + back again (re-raise the exception), or alternatively execution could + proceed. + + To clarify things, the scheme looks like this +top_routine() { + // one typical idiom... + if (!waserror()){ // (1) + do_the_job(); + do other things; + poperror(); + } + + // another typical idiom... + alloc(some_memory) + lock(a_lock_held); + if (waserror()){ // (2) + free(some_memory); + unlock(a_lock_held); + nexterror(); + } + poperror(); +} + +do_the_job(){ + if (something fails) + error(msg); +} + + Things to note: poperror would remove the label pushed by waserror; + error would jump right to the line of waserror again, but that would + make top_routine follow the else arm in 1, and the if arm in 2; + nexterror would jump to whatever outer routine called waserror before + top_routine was called, telling the caller that we suffered an error. + In the case nexterror is called, the reason for the error would still + be msg. do_the_job does not need to return the error condition to the + caller function, and how top_Routine does not need to check for any + error condition returned by do_the_job. + + One final note, special care has to be taken when calling error (or + nexterror) because some resources could have been allocated (or locks + acquired) since the last call to waserror. Take into account that + nexterror does not know anything about either resources or locks; + therefore, the routine that did allocate/acquire those resources/locks + must call waserror to release them on errors (like 2 in the example). + To pick up an example, add the line +char *p=malloc(BIGSIZE); + + right at the beginning of do_the_job, and consider that ``something + fails''. Got the picture? + +Error messages + + You already saw panic and a couple other routines. They are easy to + follow, therefore I will not comment on them. Nevertheless, the pprint + routine is curious. + + The pprint routine reports errors not on the console as panic does, + but on the standard error stream for the process. The kernel is + assuming that stderr is descriptor number two and is opened for + writing; not assuming too much. This is a detail that shows how Plan 9 + was built with the network in mind from the ground up. + + UNIX would print in the console any message about problems related to + the current process but not causing a panic (e.g. an ``NFS server not + responding'' when a network file cannot be used due to server + problems). The message is of interest to the process but not to the + whole system. By printing the message in the console, the user sitting + there can see the message, but the process could be started from a + terminal miles away! So it's better to print the message to wherever + the process prints diagnostics (stderr) and let the process (owner) + know. Besides, the user sitting at the console usually does not care + of any problem for processes he has not started. + + Clock, alarms, and time handling + + The clock is used to maintain the system time (when the TSC is not + available) and to implement alarms. An alarm causes a function to be + called after an specified amount of time. There is a system call + alarm(2) that can be used to request an ``alarm'' note to be posted to + the process after the given period of time. By handing the note, the + user process can achieve the effect of the alarm: calling a function + after a period of time. + + time(2), cons(3), alarm(2) are manual pages that can be of interest + for you now. + +Clock handling + + Let's see how the clock works starting at the clock interrupt. + + trap + + /sys/src/9/pc/trap.c:218 + The clock interrupt happens and l.s dispatches it to the trap + procedure, supplying a pointer to the Ureg structure. + Interrupts stay disabled. + trap.c:242,245 + For the clock interrupt, the handler was clockintr. + + trap + clockintr() Services the clock interrupt. + + clock.c:43,44 + The increment notes in the Mach structure that another tick + passed by. The call to fastticks updates the fastclock field of + Mach; that is used by non-boot processors to update their own + TSCs!. Looks like although the boot processor is in charge of + time, other processors try to be in sync. + clock.c:45,46 + The PC image in the Proc for the running process is updated to + be real one. This is also done when entering a system call. + clock.c:48 + Do some time accounting, as we will see in the next section. + clock.c:49,50 + Record execution statistics for kernel profiling, if needed. + kproftimer is a pointer to _kproftimer only when the kprof + device has been init'ed. If not doing kernel profiling, the + pointer will be nil and ignored. + clock.c:51,52 + This processor is not really active. It may be exiting (or + halted!) but it got yet another clock interrupt because + interrupts are enabled. Ignore it. + clock.c:53,54 + Some processor paniced (or started shutdown) and the kernel is + exiting. If this is running at a different processor, it + notices now and calls exit to terminate operation at this + processor. exit resets the bit for the processor in machs so + that other clock interrupts are ignored at lines :51,52. + Noticed how one processor does not perform immediate actions on + another processor? The best the author can do is to ``kindly + request'' the other processor to do something: processors are a + living thing. + + Lesson: When using multiple processes (processors) to do something, + do not directly interfere with the execution of others; ask them + for anything you want instead. This prevents dangerous race + conditions because only you can do things to yourself. + clock.c:56,62 + Alarms and clock0links serviced here! (see next section). + clock.c:64,68 + Will see in the virtual memory chapter. Some other processor + asked we to flush our MMU by reloading our page table. We do + so. The clock interrupt is a good place to see if anyone else + is asking this processor to do anything: the requester does not + need to wait too much (although it needs to wait!). + clock.c:70,75 + More scheduling affairs. Forget this now. + clock.c:76,79 + If the code interrupted was running at ring 3, account for + another tick in a counter maintained in the bottom of the + user's stack, and call segclock to do profiling on the user + code. Interrupts will be reenabled after clockintr returns to + trap, and trap returns to recover the user state. + While kernel is servicing an interrupt or a system call, + ureg->cs would not be UESEL, and no time will be charged to the + (interrupted) user. + clock.c:11,18 + To avoid synchronization problems due to multiple clock + interrupts on machines with several processors, the boot + processor does clock handling. That is the meaning of ``0'' in + clock0link. To service ``kernel alarms'', i.e. stuff that needs + to be done every tick for the kernel, links a established into + clock0link. Lines :57,62 are servicing these links. A link is + just a pointer to a clock procedure to notify of the clock + tick. addclock0linkEstablishes a procedure called at clock 0 + ticks. + clock.c:21,34 + Which ones are the links? addclock0link inserts a new link into + the list. So, grep for addclock0link! + ns16552.h:104 + The serial line UART wants uartclock be called every tick. + ../port/devcons.c:1015 + The console driver wants randomclock be called every tick. + That is to maintain the random number generator (see + cons(3)). + ../port/devmouse.c:85 + mouseclock should be called to redraw the cursor. The + author knows the user can be kept happy if the cursor + appears to be responsive, even if the machine is heavily + loaded. + It is important both to be fast, and to appear to be fast! + ../port/tod.c:47 + todfix should be called to maintain (fix!) the time of + day. + +Time handling + + The clock ticks, and every tick the tod (time of day) module updates + the system idea of the time of day. + + main... + consinit + todinit() Initializes time of day handling. + + ../port/devcons.c:471,475 + The console driver init function calls todinit (and + randominit). Remember that this driver was initialized during + boot as every other driver configured into the system. + tod.c:43,48 + todinit calls fastticks to update the hz field of the tod (time + of day) structure. Perhaps a local variable instead of tod.hz + would make it clearer that tod gets its hz when todsetfreq is + called, and not now. todsetfreq()Initialize TOD frequency. + tod.c:54,60 + todsetfreq is calculating the multiplier mentioned in the + comment at lines :8,24; read that comment now. + todfix()Updates the time of day. + tod.c:147,156 + Once per tick, todfix gets called. The last variable retains + its value from call to call, and is used to know if the last + call was issued at least one second ago. The author does not + want to do todget too often (to avoid wasting processor time), + but he wants it to run often enough to avoid overflows in the + counters used (note that there are many ticks per second). One + second appears to be a reasonable compromise. + todget()Updates the time of day and returns it. + tod.c:95,141 + todget is doing the actual time of day updating. It is used + both to update the time of day and to get the time of day. It + is usual that a routine to get something can be reused to + update such thing before accessing it. + tod.c:101,104 + If not yet initialized, the routine initializes the module by + calling fastticks and setting up the hz field. In any case, + ticks has the value for our TSC based fast clock. + tod.c:105 + tod.last has the time when todget was last called (1 second + ago). Now diff has the number of ticks passed since then. + Initially, tod.last is zero until either todset is called to + set the time of day or todget runs and notices that tod.last is + too far away in the past. + tod.c:108,109 + x has the number of nanoseconds since the epoch time. Note how + tod.off is added. It will be updated later. + tod.c:111,129 + Only the boot processor does time of day handling. Other + processors may be calling todget through devcons (cons(3)) or + devaudio (audio(3)) to get the time of day. + tod.c:114,121 + If the time of day must be adjusted, change it a bit at a time. + Values sstart and send are set by todset. The ilock is used to + prevent others from accessing tod in the mean time and also to + prevent interrupts while it is being updated. ilock is + discussed later. + tod.c:124,127 + Not too often, last is updated to record the interval since the + last call and off to record the time since epoch. + Where are overflows? last is used to get in diff the number of + ticks since the last adjustment. If diff gets too big, x could + perhaps overflow. In fact it doesn't matter where would the + actual overflow happen, what matters is that the author assumes + that diff would never be too big and the algorithm is coded + assuming that. The author is ensuring that the assumption + holds. + tod.c:132,135 + Time could go backward because time can be changed. In no case + a time change will report an earlier time next time the user + asks--that could really hurt programs that depend on the time + behaving properly. Because of the same reason, the author + adjusted time a bit at a time in the above lines, just to + permit the user to adjust the time without big jumps into the + future. + lasttime holds the time reported by gettod. One thing is what + the routine reports, and another what it believes. + tod.c:137,140 + Time of day finally reported. + tod.c:66,89 + Time is set by this routine. To see some call, look at + devcons.c:1211,1241, where the console driver accepts writes + from the user to set or adjust the time of day. A -1 t is the + convention for adjusting time a bit at a time: todset sets + sstart and ssend (and delta) so that todget adjusts time + slowly. If the time is not negative, the time is reset to the + given value. todset can adjust the time in multiple ways. Go to + devcons.c and try to see when is todset called. Correlate that + with the cons(3) driver manual page. seconds()Returns the time + of day in seconds. + tod.c:158,168 + Just to complete tod, seconds returns the time of day in + seconds, and is used mostly by drivers for time outs and time + stamps recorded in seconds. + +Alarm handling + + You now know how time goes by. User processes can know by reading from + the console driver's time file. However, users also may want to be + notified after a given amount of time. They also may want to sleep + (i.e. be kept blocked and not ready to run) during a given amount of + time. + + portdat.h:79,89 + Both Alarms and Talarm are headers for lists of processes. + portdat.h:75,576 and :585 + The Alarms and Talarm lists are linked using the palarm and the + tlink fields of the Proc structure--perhaps the names should be + more uniform here. The author keeps the Alarms list holding all + processes with alarms in the current machine. Each node (Proc) + in the list keeps the alarm time in alarm and the list is kept + sorted by call time. The list Talarm is analogous but maintains + sleeping processes. + + syssleep() sleep system call. + + sysproc.c:478,493 + syssleep calls tsleep to put the calling process to sleep. + + sysalarm() alarm system call. + + sysproc.c:495:499 + sysalarm calls procalarm for the same purpose. In both + routines, arg[0] is the period of time for sleeping or for the + alarm. (see alarm(3)). Forget a bit about tsleep and look into + procalarm. + + sysalarm + procalarm() Sets up an alarm for the process. + + alarm.c:84,87 + old set to the previously set value for the process alarm. (did + you read alarm(3)?). The previous value is recovered by looking + at time in the boot processor. + alarm.c:88,91 + Canceling an alarm. alarm is set to zero, and it will be + ignored later by checkalarms. + alarm.c:92 + The absolute time for the alarm computed by looking at time in + processor 0. Using absolute times for alarms lets the author + compare the processor time with the alarm time without much + arithmetic nor race conditions. It also avoids adjusting the + alarm field as time goes by. + alarm.c:94,102 + First the Alarms list locked, to avoid races with other + processes using alarm or the alarm list--e.g. alarmkproc uses + the list to notify expired alarms, and should not use the list + while it is being modified. Then search any existing alarm + entry for the current process. (Saw the + pointer-to-pointer-to-node thing again?) Line :98 removes the + entry if it exists. + alarm.c:104 + By this line, the process has no previous alarm registered in + the system: not in the list, no pointer to any ``next'' alarm + entry. + alarm.c:105,116 + Alarms list not empty, the node f with the first alarm after + the one being installed is located. That node is linked after + the current process at line:109, and the current process linked + in place of that node at line :110. If this alarm is going to + be the longer one, l in line :115 points to the ``next'' + pointer in the last node, and the current process is linked + there. + alarm.c:117,118 + Alarms list empty, easy. + alarm.c:119,123 + One way or another, the current process is now linked into the + alarm list, the alarm time is recorded, and the list unlocked. + The goto is used to share the code at done. It is breaking the + loop and the conditional in a clear way. Remove the goto, and + the code would become less clear. + + trap... + clockintr + checkalarms() Checks for expired alarms. + + alarm.c:44 + checkalarms will be called later by clockintr. + alarm.c:49,53 + It looks at the head of the alarms list (no lock!) and calls + wakeup if the first alarm expired. The list is not locked + because the kernel still runs with interrupts disabled and + because it is checkalarms the one removing alarms from the + list. So, it is safe to look into the first node because it + would not disappear under checkalarms feet. Can you tell know + why to cancel an alarm the alarm field of Proc is set to zero? + By the way, what happens if while the alarm is pending the + process dies? Hints: the alarm list points to processes; a zero + alarm is ignored; alarm removes any pending alarm before + installing the new one. + Ignore the rest of checkalarms by now. + + alarmkproc() Entry point for the alarm kernel process. + + alarm.c:12,38 + Remember from the previous chapter that a kernel process is + running alarmkproc? We have an endless process scanning the + alarm list. The first time it entered the loop, it locked + alarms, saw that no alarm was pending, unlocked it, and called + sleep on alarmmr. So, by the time a process is setting up an + alarm in the code just discussed, alarmkproc was probably + ``sleeping on alarmmr''. The call to wakeup at line :53 awakes + alarmkaproc and it continues running right after line :36. (The + return0 is a function that returns zero, but ignore that now). + The author uses a kernel process to post alarm notes to + processes with expired alarms. This process is subject to + regular process scheduling and may sleep when locks cannot be + gained. + alarm.c:18,19 + The current time recorded in now, and the list locked. If the + list cannot be locked because other processor is calling alarm, + the kernel process will wait here until the lock is gained. + alarm.c:20 + Pick up the head of the alarm list, and keep on scanning while + the alarm time is past. The alarm does not happen at the exact + time it was scheduled at; it may happen later. + alarm.c:21 + If the alarm was canceled, alarm is zero and we must ignore the + entry. + alarm.c:22 + The lock on debug is needed to post the alarm note. If we + cannot get it, better break the loop and go to sleep until next + time checkalarms awakes alarmkproc again--yes, starvation is + theoretically feasible, but so improbable that who cares? + I hope you will appreciate that there are algorithms that are + theoretically not good, but the author still prefers to use + them than to modify them to keep theoreticians happy and incur + into more overhead. This does not means that theory is not + important; this only means that you have to balance theory with + what you know from practice. + alarm.c:23,28 + An alarm note is posted for the process, debug unlocked and the + alarm reset (to zero). Any error during postnote is ignored + (poperror!). The alarm kernel process better keeps on trying to + post alarm notes, than die if an error happens while posting + one. This is one place where waserror is called not to + deallocate resources on errors, but to ignore errors. + + trap... + clockintr + checkalarms + + alarm.c:55,56 + Back to checkalarms, it does by itself the processing of + ``sleep alarms'' using the Talarm list. If the list is empty, + nothing else has to be done. + Can you guess why the author uses two different alarm lists? + alarm.c:58,73 + For any talarm expired, a wakeup on trend is issued (and the + process removed from the talarm list). When twhen is zero, the + timer is ignored. + This is less serious than posting a note, and I guess that is + the reason why talarms are handled directly by checkalarms. + Talking about reasons, there is one for having two lists + (Talarm and Alarms), a process may setup an alarm and go to + sleep waiting for the alarm to happen. So, two different lists + have to be maintained. The Alarms list always has a postnote as + the associated action and does not need to accept a + user-supplied handler. + Talarm keeps kernel timers used whenever the author wants to be + notified after a while. Alarms keeps alarms set for user + processes. More clear now? + + syssleep + tsleep() Sets up a timer and puts the process to sleep. + + proc.c:525,570 + tsleep is the one placing processes into the talarm list. A + function and an argument is given. The ``t'' is Talarm is for + ``timer''. The kernel uses Talarms to setup timers that call a + given function when expired. After the discussion of Alarms, I + think the code should be mostly clear. tsleep can be called + several times for the (current) process (cf. lines :538,548) + and the previous timer is canceled in that case. The sleep call + in line :567 is the one that actually makes the process sleep. + I defer the discussion on sleep/wakeup until later. + delay()Waits a bit. + clock.c:83,100 + To complete the discussion about timing, delay routines should + delay for so few time that they loop to implement the delay. It + would not pay to setup a timer because of the small delay time. + (Well, admittedly, delay is called to make the kernel wait for + long periods of time too; guess why?) + + Scheduling + + Plan 9 has preemptive scheduling, which means that from time to time + processes are preempted and moved out of the processor.

That context was probably saved at line + :100 when the new current process was last preempted. gotolabel + reloads the the stack and PC, pretending to return 1 from the + setlabel that filled up the label. the kernel switches to the + kernel stack for the coming process. We end up as shown in + figure [206]4.3(e). + proc.c:101 + setlabel returned true, so procrestore is called to reload + machine dependent processor context, interrupts are allowed + again, and sched returns. For the PC, procrestore is defined to + do nothing (../pc/fns.h:98). Probably, the setlabel for the + current process was made while running sched, called from + clockintr, called from trap, so the return starts the unwinding + of the kernel stack. When trap finally returns, the IRET in l.s + will reload the saved Ureg for the current process--see + fig. [207]4.3(f). + + One more note: the state of the new current process could be other + than sown in this example execution. In general, that process could + have a kernel stack corresponding to any path of execution leading to + a call to sched. You will see more examples of that during this + chapter. + +FPU context switch + + You saw how procsave and procrestore were used to save and restore the + FPU state.

As it is FPinactive, its FPU context was + saved and must be reloaded. Lines :533,534 do that. The process + is now FPactive, as it was before the first time it was + preempted in our example. I hope you will see how the author + avoids switching the FPU context when the process does not use + the FPU. + Some other OSes try to avoid even saving the FPU state, by + keeping track of who did use the FPU last and saving that state + only when it is absolutely necessary--i.e. before another + process uses it. But, take into account that Plan 9 runs on MP, + and the FPU state might be loaded into a different processor + the next time. Things are more simple in the way they are in + the code, and fast enough. + +The scheduler + + How does runproc select the next process to run? It applies a + scheduling policy to select a process. Let's look at it. But we should + start by the routine allowing processes to run. + + Getting ready + + ../port/proc.c:24,33 + Processes willing to run are either Running, or they are Ready + to run. Ready processes are linked into Nrq scheduler queues. + Each queue has processes of a given priority, and high-priority + processes get more CPU than low-priority ones. Unlike + UNIX[208]8.1, Plan 9 uses higher priority values for higher + priorities! + + ready() Puts a process in the ready queue and recalculates priority. + + ../port/proc.c:142 + Before running, the process must be set Ready and linked into a + ready queue--so that later runproc can pick it up. + proc.c:147 + With interrupts disabled (because nobody should touch the + scheduler queues), + proc.c:150,153 + if the process was running (is being preempted), rt is + incremented. rt counts the ``running time'' for the process + measured in quanta. Every time the process goes from Running to + Ready, rt is incremented. So rt measures how many full quanta + the process just consumed. pri is set to the formula: + + \begin{displaymath}\frac{\frac{\mathtt{art}+2\mathtt{rt}}{4}}{\mathtt{ + Squantum}} \end{displaymath} + proc.c:153,157 + if the process was not running (it is not being preempted), the + average running time, art, is set to + \(\frac{\mathtt{art}+2\mathtt{rt}}{4}\) , and pri is set to + + \begin{displaymath}\frac{\frac{\mathtt{art}+2\mathtt{rt}}{4}}{\mathtt{ + Squantum}} \end{displaymath} + --rt is reset to zero. Wait a bit to understand what is going + on and keep on reading. + Squantum is set to \(\frac{\mathtt{HZ}+\mathtt{Nrq}-1}{ + \mathtt{Nrq}}\) in proc.c:138. If the number of run queues is + small with respect to the machine HZ (ticks per second), + Squantum is almost \(\frac{\mathtt{HZ}}{\mathtt{Nrq}}\) , + dividing the HZ evenly among the run queues. If Nrq is big + regarding HZ, Squantum is almost + \(\frac{\mathtt{Nrq}}{\mathtt{Nrq}}\) . But this formula is + empirical and only the author knows how it was adjusted to + yield the current expression. For our PC, HZ is 82 and Nrq is + 20, yielding a Squantum of 5. To augment pri in one, rt has to + be incremented by 5/2, or art has to be incremented by 5. + So, every time the process gets Ready, (i.e. is preempted), pri + increases slowly as rt and art increase. rt influences more pri + than art does. Things can change because if the process leaves + the processor voluntarily (i.e. gets blocked, and after a while + it goes from a non-ready state to Ready) its rt is set to zero, + and its art gets decreased. The order of lines :154,157 is + ensuring that changed values are used next time and not now. + proc.c:158,160 + Here it is, pri is set to basepri minus the pri value just + computed. If the computed pri was small, the process priority + would be close to basepri; otherwise it can go all way down to + lower values, or even zero. So, for the process, it is bad when + the computed pri gets big. Should the process not block, + neither rt nor art would be decreased, so the computed pri gets + bigger and basepri-pri would be smaller; should the process + block, rt will be reset, and art will be decreased so that the + computed pri gets smaller and basepri-pri would get closer to + basepri. If the same process keeps on blocking (e.g. gets + Running, computes a bit, reads a file and blocks, gets + unblocked, and so on), its final pri will end up being basepri. + If the process keeps on running, its final pri will be very + low. Interactive processes tend to block, and they are not + penalized; CPU intensive processes are penalized. By the way, + do not pay much attention to the exact details of the formulas, + other similar ones are likely to work too; these things come + out of the author's experience with the system: they are + empirical. + Did I already said that these things are empirical? Don't + forget. + proc.c:162,170 + If the process basepri was above PriNormal, avoid the priority + decreasing too much. If the process is waiting for a lock, its + priority would be just PriLock. Otherwise, its priority is the + pri just computed. + portdat.h:522,525 + PriLock is 0, a very low priority value. If the process is + waiting to gain a lock, it is not doing anything useful (yet), + so the system penalizes it. It is better to let the process + holding the lock run, and penalizing ourselves is a fine way of + favoring that. Besides, note that PriKproc (basepri for kernel + processes) and PriRoot (basepri for processes running /* files) + are above PriNormal. That means that both kernel processes and + ``root processes'' will be kept above priNormal, no matter what + they do. The system gives them priority over normal process, + that are below PriNormal. Processes in both priority classes + (above and below PriNormal) get their priorities adjusted + during time, but they stay within the same class. + Both root processes and kernel processes are working on behalf + of the whole system. It makes sense to give them priority + because otherwise the whole system would suffer. Try to find + out which ones are the kernel and root processes in your Plan 9 + box (hints: how are you using your local disk files? how are + you talking to other nodes in the network? how are you using + your swap file? did you look at the mkfile?) + proc.c:171 + There is a run queue for each priority level. Set rq to be the + queue for the process priority this time. + proc.c:173,184 + The process is set Ready and linked into its priority queue. + readytime is set to the time the process was set Ready. + proc.c:185 + If interrupts were enabled at line :147, they are enabled now; + otherwise they stay disabled. The reason for using splx is that + ready must both lock the run queue and disable interrupts; as + ready can be called either with interrupts enabled or disabled, + the author restores things as they were. + + In few words, you now know that Plan 9 uses dynamic priorities within + two priority classes. + + Picking up a process + + Finally, sched calls runproc to pick up a process to run. You already + read runproc in the previous chapter, but let's look at some details + now. + + sched + runproc() Elects a process for running. + + proc.c:204 + Once out of four times, runproc forgets about processor + affinity and priority, and picks up the process waiting + longer--trying to avoid starvation and to balance the load of + processors here. + proc.c:211,219 + Low priority queues are scanned first! xrq points to the run + queue with the minimum readytime found for the head process, + and rt is set to the minimum readytime for that process. By + line :219 the lowest priority process sitting at the head of a + run queue that was ready before the other ones is located by + xrq. Just the head is used, to avoid locking the ready queues + while scanning for processes. + proc.c:220,226 + If there is such a process, rq is set to the queue where it + stands, and p to the process selected. The goto goes to the + place where runproc tries to run it. If there is no such + process, runproc loops again; but next time it will honor + priorities and affinity. If the process is not wired to the + processor, movetime is set to zero, that is a really small + value and will allow the process to move. + proc.c:232,241 + Three out of four times, run queues are scanned from high to + low priority; as they should. If there are no processes, + runproc keeps on looping. The process chosen is the first one + that either + + is the first in the queue that reached its movetime (did not + moved recently; same reasons as above), or + + is the first in the queue that did run on this processor (to + keep processes running within their favorite processors). + By the way, the author didn't really choose a process, but a + run queue instead! + The queues were not locked. But the worst thing that may happen + is that the process gets removed from the ready queue (by + another processor) and runproc will find its rnext pointer to + be nil. Since Procs are allocated statically in a big process + table, there are no worries about crossing a dangling pointer. + proc.c:245 + got a process. + proc.c:246,248 + Someone is using the queues (more than one processor), try + again. + proc.c:250,255 + Now a process is chosen, but using the rq selected before. If + things have changed, the fortunate one may be different from + the process than caused this ready queue to be selected--this + is the price for avoiding locks before. l is set to the process + before the one selected, and p to the first one with affinity + for this processor: the selected one. + proc.c:260,263 + No process selected, try again. If the reason was that no + process had affinity for the processor, in a couple of loops + runproc will ignore this fact. + proc.c:264,271 + The process removed from the ready queue. It is no longer ready + but running. l is used to remove it from the list. Counters + adjusted accordingly. + The process rnext is not cleared!, if any other processor is + scanning through the ready queues, it could still jump over to + the previously next process in the ready queue, even though the + process is not ready. The author is careful to avoid + unnecessary locks in places where locking would mean severe + performance degradation. + proc.c:272,273 + A scheduling bug? + proc.c:276,280 + And there it goes. sched will switch now to it, as we saw + before. + + Processes tend to be chosen from the head of the list, and are + inserted at the tail in ready. The effect would be a round-robin for + processes with the same priority--if you forget about affinity or if + there is only one processor. + + There is one thing to consider. What if a high-priority process was + blocked, and it suddenly gets Ready? That can happen because we are + running a low priority process and an interrupt notified the kernel + that the event the process was waiting for, just happened. The answer + to the question is in trap. + + trap + + ../pc/trap.c:255,265 + Conditions say that: it is an interrupt but not the clock or a + timer; there is a currently running process, and there are + higher priority processes waiting. Interrupts happen often, but + clock and timer interrupts happen really often. Checking for a + higher priority process when a frequent (but not ubiquitous) + interrupt happens is a way of checking often (but not always!) + for a high priority process. The preempted flag is set when the + author commits to preempting the current process in favor of + the higher priority one, the check at line :258 ensures that + this code would be ignored if the process is already being + preempted. A simple call to sched ensures that the + high-priority process will be able to run. + sched will not return before the other process runs. When it + returns (the current process has been switched back to the + processor), preempted will be reset, and another interrupt may + yield to a new preemption. + The slphi at line :262 is problematic, because the new + interrupt might cause a preemption before doing a + return-from-interrupt for the current one. Think that each + interrupt pushes more frames into the kernel stack, and they + are popped only when returning from the interrupt. If enough + interrupts arrive, the kernel stack would overflow and the + system would probably crash. But the preemted check seems to + suffice to avoid that. + + You know affinity, but processes can be also wired to a processor. + + procwired() Wires a process to a processor. + + proc.c:354,383 + procwired wires p to any processor (if bm is less than zero), + or to the processor specified by bm otherwise. Most of the + routine is picking up a processor to wire the process to. The + one with less wired processes is used. Perhaps a new m->nwired + field would save most of this code. A big movetime is given to + the process so it never(?) moves. + + Finally, I don't discuss it, but accounttime in + ../port/proc.c:1210,1233 maintains values for processor load averages + and process run times. + + Locking + + During the description of what the code is doing, you saw lots of + locks and locking routines. I skipped all of them. Now it's time to + discuss locking one you know about process scheduling and process + priorities. + + Because Plan 9 runs on MP machines, there are several locking + primitives employed. Let's see them from the most simple to the most + complex. + +Disabling interrupts + + Remember that within the kernel setlabel and gotolabel are used to + provide coroutines. Therefore, within the kernel, the kernel decides + when to leave the processor by using gotolabel in favor of another + kernel routine. So, you could say that ongoing system calls for other + processes are not an issue regarding mutual exclusion for critical + regions within the kernel. + + What? You don't understand the meaning of ``mutual exclusion'' or + ``critical region'' (go, reread the material for the OS course you + attended several years ago and come back later). + + However, while the kernel is executing a routine in favor of a user + process, an interrupt may arise. The interrupt will start a different + routine of the kernel while the previous one is stopped. If a system + call is being executed and an interrupt arrives, the interrupt routine + can try to access resources used by the previously ongoing system + call. Therefore, the kernel must prevent interrupts from happening + while touching data structures that can be manipulated by the code + executing after the interrupt. If you take into account that an + interrupt can lead to the suspension of an ongoing system call and a + context switch to another process, you can imagine that code executing + after the interrupt can touch almost any data structure in the kernel. + + According to what I just said, if there is a single processor, + disabling interrupts would ensure mutual exclusion among processes + while executing within the kernel. While touching an important data + structure, the kernel can disable interrupts and it knows nothing will + ``preempt'' it in the meanwhile. There can be more than one processor, + but even so, there are structures that are handled (read: written) + only by one processor (e.g. Mach for each processor) and can be + protected by disabling interrupts. Other critical regions, like the + code doing a context switch for a process, are also protected this + way. How are interrupts enabled and disabled? + + The abstraction used to enable/disable interrupts is the ``processor + priority level''. Imagine that the processor is running at a given + priority (0 or 1). While running at a low priority, interrupts + (high-priority events) can interrupt the processor. While running at + high priority, interrupts cannot interrupt the processor. This comes + from the days UNIX was implemented because the processor used actually + worked this way. + + spllo() Sets processor priority low. + + ../pc/l.s:433,437 + spllo (set priority level low) is used to enable interrupts. It + pushes the flags word in the stack and pops it back into ax + (the return value of spllo). The interesting part is sti, which + sets the ``interrupt enable'' bit in the flags word. The author + uses the stack to move flags into ax because the only way flags + can be accessed on the Intel is by pushing/popping it on/from + the stack. The value returned by spllo can be used to restore + the previous ``processor priority level'' (i.e. the interrupt + enable bit) as it was before the spllo. + + splhi() Sets processor priority high. + + ../pc/l.s:423,431 + splhi (set priority level high) is used to disable interrupts. + Lines :424,426 set in m->splpc the return PC as saved in the + stack by the call to splhi. That is, m->splpc holds the PC of + the instruction that called splhi; That is for profiling, but + can be used for debugging too. If somehow interrupts are + disabled and they shouldn't be, you could know who is guilty + for that. The real work is done at line :430: interrupt enable + cleared. The old value of flags is returned as in spllo. + + splx() Sets processor priority as given. + + ../pc/l.s:439,448 + splx (beware that it continues until the ret), exchanges the + flags and the value passed as a parameter. If the kernel calls + spllo and, later, passes the value it returns to splx, flags + would be restored as they were; i.e. the priority level would + be restored. Lines :440,442 are saving the caller's PC in + m->splpc for the same reason as above. Line :445 is taking the + first parameter (FP is the frame pointer). + ../pc/l.s:450,451 + spldone is not used as a function. If spllo or splx is + executing, the PC is between spllo and spldone. If you look at + ../port/devkprof.c:38,43 you will see how are m->splpc and + spldone used. The routine _kproftimer maintains statistics + about what parts of the kernel execute during what times, the + author seems to want to charge the spl times to the caller and + not to the routines themselves. + +Test and set locks + + By using an atomic tas instruction, which tests for the value of a + word and sets it to true value, mutual exclusion can be achieved even + with interrupts enabled. That is important because it is overlay + expensive to disable interrupts on all processors--and it is also + complex. So, kernel routines can agree that when a lock word has a + true value (non-zero), the critical region cannot be entered. By using + an atomic tas, the previous value of the lock can be tested and set + without race conditions. The first one to set the lock, acquires it. + Another useful variant of tas is xchg, which exchanges a register with + a memory position atomically. + + tas() Tests and sets a word. + + ../pc/l.s:462,466 + The Intel only has xchg, so tas uses the intel instruction to + emulate a tas. The parameter passed is the lock being tested + and set. The value set (0xdeaddead) is irrelevant. Line :465 is + atomic! + + xchgw() Exchanges a two words. + + l.s:472,476 + xchgw is a wrapper for the Intel instruction xchg. Two + parameters passed are the ``register'' and the memory position + being exchanged atomically. By the way, xchgw seems to be used + only the astar device, while tas is the routine actually used + for mutual exclusion by the kernel. So, if astar had another + way of doing its business, xchgw could go away--as seemed to + happen with xchgl. + + The kernel does not use tas directly, but uses routines provided by + taslock.c instead. With the help of several machine dependent + routines, most of test-and-set code is kept portable. + + lock() Acquires a test-and-set lock. + + ../port/taslock.c:31 + lock acquires a lock using tas. The Lock structure is defined + in ../pc/dat.h:24,31; you will see how it works now. + getcallerpc()Gets the PC after the instruction that called it. + ../port/taslock.c:36 + getcallerpc uses the address of the lock parameter to locate + the PC of the caller. If you now the address of the first + parameter, you can know where in the stack is the return PC and + obtain that value. The PC of the caller is stored in Lock.pc + for debugging purposes. If a lock has problems, it is useful to + know who did set the lock. + taslock.c:39 + Here it is. tas tries to set the lock, which is actually + Lock.key. If the lock was cleared before tas executed, the + return value would be zero; otherwise, the return value shows + that the lock is already held by someone else. + taslock.c:40,43 + The Lock structure is updated to record the process setting the + lock and the PC that called lock; all done. isilock is a + boolean stating that the lock was set by ilock and not by lock. + More about this soon. Most of the time, the lock would be not + set and the kernel would execute these lines. If the lock is + found to be set most of the times, that would show contention + for a given lock within the kernel. The affected data structure + would better split in several ones, or some of its parts locked + separately, and perhaps a different kind of lock used (Noticed + that Proc has several locks?). + taslock.c:46 + glare counts how many times the lock couldn't be acquired at + the first attempt. + taslock.c:47 + Trying to get the lock. If there is a current process and it is + running (i.e. the lock is not requested once the process was + committed to block) the kernel can call the scheduler to wait + for a while until the lock be released. + taslock.c:48,53 + If the scheduler can be called, save the process priority so it + can be restored later, and set the priority to PriLock (i.e. to + zero, so that almost every other process would be preferred by + the scheduler). If the process priority is kept as it is, and + the holder of the lock has a lower priority, the scheduler + could prefer to switch back to the current process instead; So, + the author is making sure that such thing would not happen. + lockwait is set in Proc to state that the process is waiting + for a lock; the scheduler would maintain the priority set to + PriLock no matter what the process does. + taslock.c:55,56 + Now waiting while trying to get the lock repeatedly. The number + of ``attempts'' is recorded in inglare. When contention for + locks appear, the author can at least now that in mean, + inglare/glare loops are needed. If the relation gets too big, + it can be a symptom that locking has to be adjusted. + taslock.c:58 + Important loop! If there are several processors, the current + one has l->key on its cache. If the processor does not write + the lock, it will not interfere other processors because the + lock value will be read from the cache. If the processor would + tas the lock instead, it could lead to a high bus + contention--because the value would be written and that usually + means that the value has to be put into main memory, or that + the processors must talk to update their caches. So, do not + even try to set the lock until we know it is no longer set. + taslock.c:59,65 + Just one processor, and can call the scheduler. Do so (see + figure [209]4.4(a)). The i counter is used to report we are + ``looping many times'' once per thousand iterations. + + CAPTION: Figure 4.4: Behavior of test-and-set locks. + + [test-and-set lock on uniprocessors.

It is better to wait for a while until + the lock is released by another processor (see + figure [210]4.4(b)). tas locks should be held only during small + amounts of time, so it would not pay to do a context switch + (see figure [211]4.4(c)). In the case of a monoprocessor, it + would be a waste to keep on looping because unless we release + the processor the lock holder would not run. Note the high + number of iterations until reporting that we have problems. + taslock.c:72 + Out of the while, so the lock was released when we last checked + it in line :58. Now try to set it. + taslock.c:73,80 + If got the lock, update the Lock structure and restore the + previous priority in case it was set to PriLock. If did not get + the lock try it again--note that no tas will be tried until the + ``lock-read-only'' while finishes. + + canlock() Tries to acquire a test-and-set lock. + + taslock.c:136,145 + canlock tries to set the lock but just once. It lets the caller + know whether the lock was acquired or not. Routines willing to + give up or to do something else when a lock cannot be acquired + can use canlock. You already saw how canlock was used by the + scheduler to give up and try again. The implementation of + canlock uses tas as lock does, and initializes the Lock + structure appropriately. + + unlock() Releases a test-and-set lock. + + taslock.c:148,158 + Releasing a tas lock is easy, just set the lock (l->key) to + zero and the next tas will return zero. Note how the lock is + checked to be set. The call to coherence ensures that the lock + value is seen by other processors--a ``no-op'' on Intels. + + ilock() Interrupt-safe version of lock. + + taslock.c:85,86 + ilock is a variant of lock. The lock routine works fine when it + comes to mutual exclusion between different processors. + However, the kernel may also want mutual exclusion between a + process running inside the kernel (e.g. a system call) and an + interrupt handler. Imagine that the kernel gets a lock on the + memory allocator, and an interrupt arrives. If the interrupt + handler wants to allocate memory, it would try to acquire the + memory allocator lock. You get a deadlock! This is shown in + figure [212]4.5. + + CAPTION: Figure 4.5: Acquiring locks without ilock. The process 1 + acquires a lock, and gets interrupted. The interrupt handler tries to + acquire the lock and has to block!. The lock will never be released. + + \resizebox{9cm}{!}{\includegraphics{ilock.eps}} + + The way to avoid the deadlock is to disable interrupts besides + acquiring the lock. By disabling interrupts, no interrupt + handler can request the lock because no interrupt handler will + run (in the current processor) while the lock is held. Other + processors are not an issue because they can try to acquire the + lock without a deadlock. + The author could disable interrupts and then call lock, but if + the lock was not acquired, interrupts might be cleared for just + too long. The ilock routine tries to acquire the lock and + restores the previous interrupt state when the lock cannot be + acquired. + taslock.c:95 + Interrupts disabled, the previous priority level kept at x. + taslock.c:96,102 + If tas got the lock, return with interrupts disabled and the + lock set. (isilock records that the lock disabled interrupts + too). The previous priority level is saved in l->sr. The unlock + routine needs that to restore interrupts to their previous + state. + taslock.c:112,113 + A single processor available, how could the lock be released if + interrupts are disabled? This message would mean that usage of + locking primitives has to be fixed. + taslock.c:117,120 + While the lock is held by another process, restore the + interrupt status. Once the lock is released, interrupts are + cleared before trying again to acquire the lock. + + iunlock() Interrupt-safe version of unlock. + + taslock.c:161,177 + Locks acquired with ilock are released with iunlock. Again, the + author ensures that it is an ilocked lock. The last two lines + are manually setting splpc to be the PC of the caller of + iunlock, and then doing the rest of splx (remember that splx + did fall down to splxpc?). + +Queuing locks + + A Lock can be used to protect small critical regions. When the lock is + being held for a long time, or when there is much contention on a + lock, another kind of lock is needed. If processes would have to wait + for a long time to acquire a lock, they better sleep while waiting. + When there is much contention for a lock, it is also better to respect + the arrival order of the lock requesters; otherwise you can get + starvation. + + ../port/portdat.h:60,66 + A Qlock is a lock that maintains a queue of processes waiting + for the lock. The head and tail fields maintain the list, the + locked flag shows whether the lock is held or not. And finally, + the Qlock structure has to be protected for race conditions: + use is a Lock that must be held to operate on the QLock. use + will be held during a small amount of time--as soon as the + process either gets the Qlock or gets queued, the use lock is + released. The author is building locks appropriate for big + critical regions and high contention using the simple tas locks + as the building block. + + qlock() Acquires a queuing lock. + + qlock.c:17 + qlock is the routine called to acquire a QLock. + qlock.c:21 + Important! to protect q, a tas lock is acquired. + qlock.c:23,27 + If the q lock is not set, set it and return. In this case the + tas lock is released; it was held only while the QLock was + manipulated. + qlock.c:28 + The number of processes queued on a QLock increased. The author + can know whether the queues of QLocks are really used or not. A + kernel is a living thing, the only way to issue a good + diagnostic is by asking it about its symptoms. + qlock.c:29,38 + The process is queued in the QLock. There must be a current + process, otherwise there is nothing to queue. See how the + process is queued in the tail of the queue? + qlock.c:39 + The process was not Ready, now it is Queueing and will not run + again until extracted from the lock queue and placed back in a + ready queue. + qlock.c:40 + The PC of the caller recorded to find out guilties for locking + bugs. + qlock.c:41,42 + The QLock was protected by the use lock during all this time; + now release the tas lock and switch to a different process. The + current process is queued waiting for the lock. + + canqlock() Tries to acquire a queuing lock. + + qlock.c:45,57 + Like canlock, canqlock tries to acquire the lock and returns + reporting whether the lock was acquired or not. canlock is used + on the use lock (because canqlock should not block). + + qunlock() Releases a queuing lock. + + qlock.c:59,76 + qunlock releases a QLock. If there are processes in the queue, + the one at the head is extracted and set Ready. That process + has the lock (Hence locked is kept set to true). If there is no + process waiting for the lock locked is set to false. QLocks are + acquired in FIFO order regarding the request time. + + There are many places where QLocks are used. They are used wherever + the lock is likely to be held for a long time--and processes are + likely to wait for the lock a long time. For instance, I/O devices + like cons, pipe, etc. use QLocks because I/O operations are likely to + be slow and take a significant amount of time. + +Read/write locks + + The locks discussed above could suffice. However, many times there are + several processes accessing a data structure just for reading it, and + there are several other processes writing the data structure. It makes + no sense to serialize the readers of the data structure. When there is + a single processor, readers would necessarily read the data structure + once at a time; but on multiprocessors, several processors could be + reading the same data structure at the same time without any problem. + With the locks seen before, multiple processors willing to read the + same data structure could be stalled, waiting for another reader to + finish. That is why there are read/write locks. While you read below, + see figure [213]4.6 as an example of how R/W locks would block + readers/writers. The figure should be clear by the end of this + section. + + CAPTION: Figure 4.6: Read/Write locks. Typical scenario showing how + readers/writers acquire the lock. + + \resizebox{10cm}{!}{\includegraphics{rwlocks.eps}} + + rlock() Acquires a R/W lock for reading. + + qlock.c:79 + rlock tries to acquire a RWLock for a reader process. If will + be able to acquire the lock if there is no one writing the + locked data structure--or waiting to write. + qlock.c:83 + Again, using a tas lock to protect the lock data structure. + qlock.c:84 + Now it is important to know an overall number of readers and + writers for RWLocks; that can reveal symptoms that RWLocks are + used where a more simple lock could be used instead. + qlock.c:85,90 + writer is a counter for the number of writers. Perhaps it + should have been named writers, but there is only one writer + allowed at a time, hence the name. So, if there is no writer, + and there is no process waiting for the lock, the lock is + acquired. When there is no writer, but there are processes + waiting for the lock, that processes would be writers waiting + to acquire the lock. In this case, it is important to queue and + give priority to the writers who arrived before. Otherwise, a + continuous flow of readers might starve a writer. readers is + incremented to reflect that there is one more reader holding + this lock. There is no ``locked'' field in the RWlock; if there + are readers or writers, the lock may be locked or not depending + on who you are and who is holding the lock. + qlock.c:92 + One more reader had to wait, let the author know. + qlock.c:93,102 + The process (and there must be one) is queued in the list of + processes queueing at the lock. The queue is maintained using + the qnext field of the Proc structure. + qlock.c:103,105 + The process state shows that the queued process is queueing for + reading. As with QLocks, the process will not run until + dequeued from the lock queue and placed back in a ready queue. + + runlock() Releases a R/W lock for reading. + + qlock.c:109 + Readers use runlock to release a RWlock for a reader. + qlock.c:115 + If there are more readers holding the lock besides the one + releasing the lock, nothing else has to be done: the lock is + still held by remaining readers. Besides, if there is no + process waiting to acquire the lock, there is nothing more to + do because by updating readers, the lock is released when + readers gets down to zero. + qlock.c:120,122 + The last reader went away and there are processes waiting. The + first process waiting in the queue must be a writer--note that + should it have been a reader, it would have entered acquiring + the lock, because there was no writer waiting by that time. + There can be readers in the queue too, but they are queued + because they saw there was another process queued (and a writer + was among them) and decided not to pass it. The process state + is checked to see whether the queued process is waiting for + read or for write--see figure [214]4.7. + + CAPTION: Figure 4.7: Queueing locks. The process is just removed from + the ready queue while waiting to acquire the lock. In this case, the + lock is a read/write lock and the process state is used to see what + the process is waiting for. + + \resizebox{12cm}{!}{\includegraphics{qlock.eps}} + + qlock.c:123,128 + As the last reader is gone, awake the writer by removing it + from the queue and setting it ready. The writer counter is set + to one to reflect that one writer holds the lock. That would + prevent further readers/writers to acquire the lock. Now that p + is ready, the scheduler can elect it for running. + + wlock() Acquires a R/W lock for writing. + + qlock.c:132 + Writers use wlock to acquire the RWlock for writing. + qlock.c:138,145 + If there are no readers and there are no writers (no writer, + actually) the lock can be acquired. The PC that called wlock + and the process that acquired the lock are noted, for + debugging. For readers, the author thought it was not worth to + record that information, probably because there are multiple + readers. + qlock.c:148,158 + The process must wait until either the last reader releases the + lock, or the current writer releases the lock. The process + state is updated to reflect ``waiting to acquire a RWlock'' for + writing, and the scheduler is called. The process won't run + again until dequeued by either the last reader or by the + writer. Even if the lock is held by readers, further rlocks + will have to wait. + + wunlock() Releases a R/W lock for writing. + + qlock.c:165 + Writers releasing the lock call wunlock. + qlock.c:169,175 + If there is no process waiting, the lock is released by setting + writer to zero. + qlock.c:176,184 + If the first process waiting is a writer, it is given the lock + (note that writer is kept set to 1). The writer is allowed to + run by removing it from the lock queue and setting it ready. + qlock.c:186,187 + The process must be one waiting to acquire the lock for + reading. Otherwise, some bug caused other process to enter the + queue, or some bug caused the waiting process to change its + state. + qlock.c:189,197 + The first process waiting is a reader, but as the lock is going + to be acquired by a reader, any other reader waiting can + acquire the lock at the same time too. The author scans the + queue seeking for processes queueing for read. All of them are + removed from the queue and set ready. readers is updated to + reflect that the lock is held by that many readers. The + scanning stops as soon as a writer process is found, because + remaining readers should yield to the writer who arrived + before. + qlock.c:198,199 + It did not harm that writer was set until now, because the tas + lock was held. But better update it now. + + canrlock() Tries to acquire a R/W lock for reading. + + qlock.c:202,216 + canrlock is used as canlock, but for a RWlock locked for + reading. Perhaps a canwlock could be added for completeness, + although no one is using such a thing now. + + One comment before proceeding. When a process is being awakened to + acquire the lock, you saw how the author does the bookkeeping for the + awakened process (updating counters et al.) in the process holding the + tas lock. You will also see that when author implements note posting + and notifying, whatever can be done easily within the notifying + process is not done by the notified process. This is a general rule + that when you hold a lock and some bookkeeping has to be done for the + process being awakened, you better do it in the awakening process + before releasing the lock. Otherwise, the awakened one would have + necessarily to acquire the lock for the resource and that could lead + to more race conditions. Keep the code simple. Of course there is a + counterpart rule that if you can do something more easily in the + process awaken than it can be done in the awakening process, you + should do it where it is more simple. Keep the code simple, did I say + that? + + Synchronization + + There are several forms of synchronization in Plan 9. User processes + can use rendezvous(2) to synchronize. + + Besides, the OCHEXCL bit for permissions given to the create(2) system + call, allow processes to synchronize on their access to files: only a + process may have the file open at a time. This simple mechanism avoids + the need for complex file locking primitives found on other systems + like UNIX. This is very important since there is distributed access to + files (noticed the nfslockd process on your UNIX box?). + + Moreover, the CHAPPEND permission bit, together with the guarantee + that small writes are likely to be serviced atomically by the file + server, can be used together to add new data to a file without race + conditions. + + While in the kernel, processes sleep waiting for an event and wakeup + other processes, as you saw while discussing timers; and of course, + you have the various lock primitives discussed before. + + In this section you are going to read the code for redezvous, sleep, + and wakeup. + +Rendezvous + + See rendezvous(2) before continuing. + + sysrendezvous() rendezvous system call. + + ../port/sysproc.c:696 + sysrendezvous is called with two arguments + sysproc.c:702 + tag is arg[0] and val is arg[1]. + portdat.h:407,411 + A Rgrp (rendezvous group) is a hash table with RENDHASH + entries. + sysproc.c:703 + REND is defined in portat.h:393 to use the hash function to + locate the entry in the table. The author just applies the + modulus to the tag, that seems to be a good enough hash + function for the case. l is our entry in the hash table. + sysproc.c:706 + The list in the hash bucket is searched for a process with the + same tag. You see how Procs doing rendezvous are linked into + the Rgrp hash table using the rendhash field as the ``next'' + pointer. The code is clear, but perhaps names like ``rqnext'', + ``rendnext'', etc. would make it more clear. + sysproc.c:707 + One process called rendezvous with tag! + sysproc.c:708,710 + It is removed from the list. The value the first process gave + to rendezvous will be the value returned to the 2nd process + calling rendezvous for the same tag. The val supplied by this + 2nd process, is passed to rendval for the first process. + sysproc.c:712,713 + Waiting until the first caller of rendezvous stops running (may + be at a different processor). This is busy waiting, because the + author thinks it would be a waste to sleep until the first + process stops, and wakeup later. On uniprocessors, the process + will never be running. + sysproc.c:714,716 + Now that the first caller of rendezvous is not running, we can + mess it up. Remember, the first caller did call rendezvous. If + it was running, it was about to stop, waiting for a second + process calling rendezvous--Agree now that it would be a waste + to sleep? As the first caller is now sleeping waiting for us; + make it ready again. It will pickup rendval as the return + value--It was sleeping also in sysrendezvous. + sysproc.c:722,725 + This is the starting point for the first caller of + sysrendezvous with a given tag. Record the tag and the value so + the 2nd caller notices; and link the process in the Rgrp hash. + sysproc.c:726 + The process calling rendezvous was running; hence it was not in + the scheduler ready queue. Set the state to Rendezvous to + reflect that it is no longer Running; later it will be moved to + Ready as you saw before. + sysproc.c:729,731 + sched yields the processor. Other processes will run. The + current one will not because it is not linked in a ready queue. + When the 2nd caller calls ready for us, this process will + eventually be running, and continue by returning from + sysrendezvous with the 2nd caller's value. + One thing to note: rgrp is unlocked before returning or + scheding. After sched, no lock is necessary to complete the + rendezvous. + + This is a common scheme that you already saw several times: a process + is moved out of the ready queue, it runs and blocks due to some + reason; so it gets linked into the structure representing the reason. + Later, the structure will be scanned and the process moved back to a + ready queue. + +Sleep and wakeup + + sleep() Waits for something. + + proc.c:403,452 + Sleep and wakeup are complicated, as the plenty of comments + suggest. sleep(r,f,arg) puts a process to sleep on r due to a + reason represented by (*f)(arg). wakeup(r) wakes up a process + on r. If wakeup is called, the reason for sleeping no longer + holds. There are several problems though. + + A process may call sleep, and in the mean time, right after + starting to call sleep, another process can call wakeup for + him. + + Right after calling sleep, the condition may change and we + may change our mind and don't sleep. Therefore, wakeup can be + called for a process that is no longer sleeping. + + While a process is sleeping, it can be posted a note with + postnote. That may even make the process die. So once more, + wakeup can be called for a non-sleeping process. + Read this comment at lines :403,452, and think about it. + Perhaps the only way to make things more simple would be to + change the semantics of sleep and wakeup. + By the way, the Rendez parameter of sleep and wakeup may be + called so because it is used to rendezvous the processes + calling sleep and wakeup; but it has nothing to do with + rendezvous(2). + proc.c:458,460 + Without interrupts and locking rlock. + proc.c:466,473 + Important action, see the comment. + proc.c:475,481 + The condition changed while calling sleep; no need to sleep any + more. Note how r->p is set to nil, so wakeup knows there is + nobody sleeping there. + Can you understand now why tfn (proc.c:518,522) is given as an + argument to sleep at line :567? Beware that tfn is not up->tfn! + proc.c:487,488 + No longer Running, Wakeme is the state for sleeping processes. + Besides, the process is sleeping on r. Any postnote will notice + the state and update p->r to be nil; so that a later wakeup + notices that there is no process to wake up. + proc.c:490,506 + Doing the work of sched, instead of calling it. Why? + proc.c:509,513 + A note was posted, report the abortion of the sleep. + + wakeup() Wakes up a sleeping process. + + proc.c:576 + wakeup will wake up the process sleeping on r, if still there. + proc.c:582,585 + Important action, see the comment. + proc.c:589,590 + The sleeper was gone. No locks by now! + proc.c:592,593 + Now getting the lock + proc.c:595 + The process could go away between line :588 and this line. So + check that r->p is still there and is the p we know. Both + checks are necessary since a different process could sleep on r + between both lines. + proc.c:596,601 + The process is awaken and placed back in the ready queue. The + return value is true if a process was awaken. + proc.c:604,607 + One way or another, we are done. + + postnote is discussed together with notes in the next section. + + There is a routine used to put the process to sleep for a while, + awaiting for a resource. + + resrcwait() Waits for some time due to a reason. + + pgrp.c:261,277 + resrcwait uses tsleep to wait for a resource. It sets the + ``ps'' state to let the user know what is the process waiting + for, and sleeps for 300 ms. return0 (a procedure returning + zero) is used so that when sleep checks the condition function, + it returns zero and sleep puts the process to sleep. rescrcwait + seems to be used just to await for free slots in the process + table. + + Notes + + Users make system calls to notify and noted to handle notes. See + notify(2). Notes are posted by writing to a note file or by the + system; see proc(3). + + The desing of Plan 9 notes is nice is that it services several needs: + the kernel can use it to notify of exceptional conditions to the user + process, and the proc(3) files can be used by user code to notify + anything even through the network. Other systems (e.g. UNIX) do not + have a means to asynchronously notifying to processes over the network + (e.g. you must use either sockets or signals for that, and signals do + not work across the network!). + +Posting notes + + sysnotify() Sets up the process handler for notes. + + sysproc.c:572,578 + sysnotify registers the handler for notes in the field notify + for the current process. The address is checked to be valid + because the user could lie--if the address is zero, the handler + is being canceled. + sysproc.c:580,586 + sysnoted simply does nothing. Why? the noted system call has + nothing to do, the work is done in trap.c. + Let's start by posting a note to a process. + + syswrite + procwrite() Handles writes for proc(3). + + devproc.c:720 + A write to /proc/n/note leads to a call to procwrite with Qid + Qnote. Remember the section on files in the previous chapter? + devproc.c:721,724 + It is an error to post a note for a kernel process. It is an + error to post a note message longer than ERRLEN characters. + devproc.c:727 + Here is where the note is posted. postnote does the work. If + you grep for postnote, the kernel calls it in several other + places, where it feels that the system must post a note to + notify something. + devproc.c:677,679 + There is another way for the user to post a note, send it to a + group of processes. If the file written is notepg, pgrpnote + posts the note... notepg()Sends a note to a group of processes. + pgrp.c:12,40 + ...by scanning the whole process table searching for not-dead + processes with the same noteid. In the end, postnote is called + to post notes; kernel processes are not notified. The author + scans the table without locking the processes, and when he + thinks he got a process, a lock is acquired and the check + repeated--now without races. This pattern is used in several + other places as you will see. Any error in postnote is ignored. + + syswrite + ... + postnote() Posts a note to a process. + + proc.c:611 + The note is n, the process notified is p, not the current + process. postnote must lock debug in the Proc affected, but + will do so only if dolock--i.e. some caller of postnote does + not hold the lock. + proc.c:623,624 + flag is NUser if postnote is called by devproc--the user wrote + the note file. nnote is the number of notes posted (but not yet + notified) for the process. So, if the kernel posts the note and + there is no handler or p->notified, the number of notes is set + to zero. notified is true while the process is being notified. + Rationale: if there is no handler, there is no point in keeping + previous notes so set the number to zero; if the process is + being notified, and the note comes from the kernel, forget + about pending notes after then one being notified, because the + kernel one is likely to be important. Only when there is a + handler and a pending note, nnote is preserved so that the + previously posted note is kept for the user before the one + posted by the kernel. + proc.c:626,631 + The note array holds the at most NNOTE notes posted to the + process. If there is space, nnote is adjusted and the note + copied (posted) to the slot in the array. Both msg (the note + text) and flag (the note flag) are kept in the array. postnote + returns true if the note was posted. + proc.c:632 + There is a note for the process, let it know. + proc.c:636,645 + Race against sleep/wakeup. Get the lock and look at p->r. If + non-nil, the process is sleeping. Note the ``paranoid'' check + to ensure that the race did not mess things up. Locking for + these three routines is so complex that security must go first. + The process is pulled out of the sleep and made Ready again. A + later wakeup would notice that r->p is zero and do nothing. + proc.c:649,650 + Unless the process is doing a rendezvous, the post is done. The + process will notice the post and handle things itself. + proc.c:653,664 + Besides sleeping, the other reason a process may be waiting is + on a rendezvous. Both sleep and rendezvous may be interrupted + due to a note. If the state is Rendezvous (note the double + check once the lock is gained!) the value to be returned is set + to the representation of -1 in two's complement (see + rendezvous(2)). The process is then removed from the Rgrp hash + queue and set Ready. Compare this code with the code in + sysproc.c:708,715. In postnote, there is no need to wait until + the process stops running (if it was so). + + Now that the note is posted, and the notified process is ready, it + will run sooner or later. + +Notifying notes + + Imagine the just notified process starts running. + proc.c:475 + If the process was in sleep, or enters sleep, notepending is + seen, and the ongoing system call is aborted at line :512. The + notepending flag is reset (now the process knows it has notes), + but nnote is still non-zero as there are notes in the process' + note array. Something similar happens to processes with notes + posted while doing a rendezvous. + ../pc/trap.c:532,538 + In any case, when the notified process runs again, it will be + inside the kernel, probably in sched or aborting a sleeping + system call. One way or another, as procedures return, the + process will reach trap (or the last lines of syscall). Ignore + lines :532,533 by now. Right now, the process is as depicted in + figure [215]4.8(a). + + CAPTION: Figure 4.8: Notes are handled by the notified process. notify + sets up the context for the handler.

If the kernel posted the note, + it is likely that the instruction pointed to by the user PC, + caused a trap that caused the postnote. Therefore, the value + for the PC is valuable to fix the bug. + trap.c:568,574 + If the note was not posted by the user, and there is no handler + (notify is null) or the process is currently handling a note, + the process is killed. pexit does the job. This is reasonable + since the handler is probably faulting and it makes no sense to + give it a second chance. + trap.c:575,579 + The process is handling a note right now, do nothing; The check + could be done at line :537, but notify would then have no + chance to kill the process in case something caused a kernel + posted note. Think of a process using an illegal instruction + while running the handler for the note. + trap.c:581,584 + Default action for user posted notes when there is no handler: + die. + trap.c:585,586 + Starting to setup the user stack to run the note handler (see + figure [216]4.8(b)). We know there is a handler. Here the + author makes room for a copy of the saved Ureg in the user + stack. When the process is being notified, the note handler is + supplied with a copy of the saved Ureg; the handler can make + changes in the copied Ureg and the kernel will reflect those + changes in the real saved Ureg. That way, a user can repair the + cause for a note by changing the noted process context. Can you + see that the kernel is using ``user virtual addresses'' + directly? That is feasible because the kernel now runs within + the context (i.e. address space) of the notified process. User + virtual addresses can still be used from the kernel, they must + be checked though to ensure that they really exist and have + appropriate permissions. + trap.c:588,593 + The user could lie regarding the address of the handler or its + stack. Ensure that both the handler entry point and the place + in the stack where handler arguments are copied are valid + addresses. If they are not, the process dies.

See + later. + trap.c:595,597 + up->ureg is set pointing to the copy of the saved Ureg in the + user stack. This is the copy for the user, and not the real + Ureg (which is the parameter ureg). The real Ureg is copied + into the user stack and a pointer to the just copied Ureg + pushed on the user stack. + trap.c:598 + What? did this before. Perhaps line :595 should be deleted? + Looks like the old up->ureg should be saved in the user stack + before being updated to point to the current User's copy of + Ureg. Note the comment. + trap.c:599,600 + Make room in the stack for the just pushed Ureg* and the note + message; copy the note message. + trap.c:601,604 + Add room for three words: the return program counter, the + pointer the the copied Ureg, and the pointer to the note + message in the user stack; and initialize them accordingly. Why + is the return PC being set to zero? + trap.c:605,606 + The real (note: ureg and not up->ureg) saved user stack pointer + set to the new value for the handler. The real saved user PC + set to the address of the handler (kept in notify). After trap + returns leading to a return from interrupt, the reloaded + process context would make it run the handler as if it had been + called. The arguments are as they should be, but the return PC + for the handler is zero! A return will cause a page fault + (because address zero is not valid) and the process will surely + die--because the system would post a note during the execution + of the handler. But you know that a note handler must not + return, you read noted(2), right? + trap.c:607,610 + One the note is notified, shift remaining notes (if any) to + remove the first one. lastnote keeps a copy of the note just + notified--used for debugging and while returning from the + handler.

After noted returns, the return + from interrupt will reload the (fixed) process context. + Usually, the user PC and SP in the fixed Ureg would be those + corresponding to the user context before the process was + notified (as shown in figure [218]4.9(b)). + trap.c:664 + The argument to noted specifies what to do next. + trap.c:665,674 + Be it NCONT or NRSTR, the pointer to current copy of Ureg for + note handlers is set to its old value. (But remember line :595! + A bug there?). + trap.c:676,690 + NSAVE arranges for the user stack to be almost preserved as it + stands (see figure [219]4.9(c)). The user stack is set above + the old Ureg, leaving place for three parameters and a fake + return PC; a pointer to the oureg is set as the first + parameter. But, parameters for who? If you ask this, did you + read noted(2)?. The note handler calling noted has adjusted the + PC in its copy of the Ureg so that a different routine is + called when it returns; the NSAVE is set for noted to let it + know that it should keep a handler stack frame for the routine. + Using this ``trick'', the user can chain handlers for notes. + trap.c:691,695 + None of the known flags, let the user know and continue as if + NDFLT was said. + trap.c:696,702 + The process did not say NCONT to let the process continue, and + did not say NSAVE to chain another handler. The reason for the + note is not likely to be repaired and the process must die. + When noted returns, the saved Ureg is reloaded (including any + fix from the note handler), and the process resumes operation. + + By the way, most of the blocks with qunlock, pprint, and pexit used to + handle errors could be folded into a common error handling block by + using a goto like other kernel routines do; and perhaps the arithmetic + done with the user stack pointer could be simplified a bit. + + Rfork + + Now it's time to see how are processes created and destroyed. The + system call used to create a process is rfork. Read the rfork(2) + manual page. + + Plan 9 follows UNIX (as with many other things) in that processes are + arranged into a hierarchy. The system creates an initial process, and + remaining ones are created using rfork as descendant of the first one. + + Using a hierarchy of processes is good in that provides a natural + means to share resources, by setting them up in the parent before + spawning any child. Unlike UNIX, Plan 9 is able to adjust the + resources a process has, including its name space, so that any process + can get a brand new instance of the resource, or a clone of the + resource. But you already read this in the manual page, right? + + Although the proc(3) device permits handling of processes using files + (over the network), typical operations of process creation and program + execution are performed by regular system calls on the local node. + Moreover, processes can only share resources (namespace, descriptors, + etc.) within a node. This is not a severe problem, because name spaces + can be constructed to use the same resources (files) over the network. + The approach chosen by the author is simple, yet effective. + + sysrfork() Entry point for rfork. Creates new processes or adjusts the + current process resources. + + ../port/sysproc.c:20 + sysrfork is the entry point for the rfork system call. It is + called from syscall in ../pc/trap.c. + sysproc.c:31 + The flag supplied to rfork is very important, because it + controls what rfork will do. It is made of an OR of bits, + stating that particular resources for the process should be + (re)created, duplicated, or shared. + sysproc.c:32,38 + The user cannot request that file descriptor group be both + copied (RFFDG) and and cleaned (RFCFDG). The same for the name + space and the environment. Flag names are not so hard to + remember: they all start with RF (for RFork). Now, take the + file descriptor group (FDG) as an example: to share it, say + nothing; to duplicate it, say RF and FDG, i.e. DFFDG; to clean + it, put a C before the flag name, i.e. RF and C and FDG, that + is RFCFDG. Calls to error will jump to the label set by the + last call to waserror--at ../pc/trap.c:496. + sysproc.c:40 + Important!, if RFPROC is said, the system must create a new + process and use remaining flags to set up its resources. If + RFPROC is not said, changes affect the current process. The set + of flags for rfork is a kind of micro-language, used both to + adjust resources in the current process and to control the + initialization of resources for the new process. Lines :41,78 + are executed when rfork is adjusting resources for the current + process. + sysproc.c:41,42 + RFMEM requests data and bss segments to be shared between the + parent and the child, but there is no child. RFNOWAIT request + the child to be ``independent'' of the parent--more about this + later. As there is no new process, these flags have no sense. + sysproc.c:43 + the fgrp has to be either copied or cleared. It makes sense to + copy the fgrp even when there is no new process. The fgrp may + be shared among the current and other processes, the current + process is probably going to adjust its fgrp and does not want + to disturb the other processes. By calling rfork with RFFDG + set, the process can ``clone'' the fgrp and get its own copy. + sysproc.c:44,48 + up->fgrp set to either a duplicate of up->fgrp, or to a + duplicate of nil--i.e. to a fresh new one. You already saw in + the last chapter how dupfgrp works when creating a new group. + dupfgrp()Duplicates an Fgrp. + pgrp.c:185,208 + When the fgrp is not being created, but being cloned from an + existing one, these lines execute. Lines :187,190 get the + number of used entries in the cloned group--and round that + number to a multiple of DELTAFD entries. Later, memory for the + array is allocated, the reference count set to one and the + array initialized from the cloned one. incref(c) adds an extra + reference to each channel in the cloned group. The author + ensures that the fgrp appears to grow in chunks of DELTAFD + entries, no matter if that was really the case or not: he + sticks to his design. + closefgrp()Releases a reference to a Fgrp. + sysproc.c:49 + The process got a new fgrp, so the old one is no longer + referenced by the process. closefgrp releases the reference to + the previous up->fgrp; if the reference count gets down to zero + (no other process using this fgrp), all file descriptors in the + fgrp are closed and the fgrp deallocated. + sysproc.c:51,59 + The name space adjusted. pgrp is actually the name space group. + First, a new pgrp is created (an empty mount table for the + process). If the pgrp is to be copied, pgrpcpy duplicates in + up->pgrp the old name space. There is no duppgrp routine + (although a simple wrapper for pgrpcpy could be created to make + the code look like the one for fgrp). The noattach flag + prevents mount and attach from being used on the name space. + The old pgrp value is set for the new name space. Otherwise, a + process could bypass the noattach flag by duplicating the name + space. I think that a duppgrp routine could take care of this + detail too. Finally, the reference to the old name space group + is released. + sysproc.c:60,61 + If RFNOMNT was set, forbid mounts and attachments on the name + space by setting the flag. + sysproc.c:62,66 + Start a new rendezvous group for the process. That is used to + avoid clashes in the rendezvous tag namespace, and to prevent + some processes to rendezvous with others. A new rgrp is created + and the reference to the one dropped. + sysproc.c:67,74 + Environment group adjusted. Again, I miss the existence of a + newegrp and/or dupegrp routine--But that's just a naming issue + mostly. The creation of a new egrp is done by allocating it and + setting the reference counter to one. If the environment is to + be copied, envcpy will recreate in up->egrp the variables found + in the old environment. + sysproc.c:75,76 + Create a new note group for the process. Similar to what was + done for rendezvous, but more simple. Remember that the whole + process list is scanned to determine who belongs to a process + group when posting notes? To create a new note group it + suffices to get a new noteid value. + sysproc.c:80 + The previous lines were executed only when resources for the + current process should be adjusted. Did not return at line :77, + so the caller wants a new process. Allocate it at this line. If + you remember from the previous chapter, newproc allocates a + free Proc entry and initializes it with everything set to null + but for the kernel stack, the process pid and the process + noteid. The process state, the ``ps'' state, and the FPU state + are set to initial values too. + sysproc.c:82,84 + The newly created process has the same FPU saved state, and + appears to be executing the same system call (number and + arguments). + sysproc.c:85 + No errors for the new process. + sysproc.c:86,88 + The new process uses the same root directory and the same + current directory. rfork usually duplicates the calling process + unless told otherwise. Now there is another reference for dot. + An incref on slash seems to be missing. I think that the author + considered it unnecessary because all processes have the same + value for slash (boot gets one pointing to the root device and + rfork makes the child have the parent's slash), the slash + channel will never be released. Nevertheless, I think it would + be better to incref/decref it. + sysproc.c:90,96 + The set of notes for the current process is duplicated for the + new one. dbgreg points to the saved Ureg after traps, none by + now. Also, there is no note handler running for the new + process, set notified to 0. + sysproc.c:98,104 + Going to work with segments, so gain the lock seglock and + prepare to release it if there is an error. waserror is used to + jump back to it on an error, release the lock, and re-raise the + error to the waserror in syscall (trap.c). dupseg()Clones or + shares a segment. + sysproc.c:105,107 + For all segments, call dupseg to duplicate the ith segment in + the seg array. The n lets dupseg know that the segment should + be duplicated and not shared or cleared. I'll get back to + dupseg on when talking about virtual memory on chapter [220]6. + The only things you should know by now is that: + + dupseg returns the segment given incrementing its reference + counter for TEXT, PHYSICAL, and SHARED segments. You see how + text segments (read only) and physical memory segments are + shared between the parent and the child no matter what rfork + is told. + + dupseg creates a fresh new stack segment and returns it, when + the segment given is a stack. The base address and size for + the new stack are the same as in the passed segment. + + for DATA and BSS segments, dupsep will add a new reference + and return the segment given (i.e. share it) or it will + create a copy of the given segment, depending on the share + flag (n). + So, after the calls to dupseg, the new process has its seg + array setup either sharing the parent's segments or with a copy + of parent's segments. Of course, text segments are always + shared with the parent and the child always gets a fresh new + stack. Apart from that, everything else in virtual memory looks + like the parent's memory; see figure [221]4.10. + + CAPTION: Figure 4.10: Virtual memory layout for a forked process. The + layout of physical memory is not really like the one shown; besides, + Plan 9 uses paging, and does not map whole segments. + + \resizebox{14cm}{!}{\includegraphics{forkvm.eps}} + + sysproc.c:108,109 + Lock released and the last error label removed. A call to error + to notify an error will jump now to the waserror at syscall: + there is no cleanup to be done here now and the direct jump to + syscall can be permitted upon errors. + sysproc.c:111,155 + File descriptor group, name space, rendezvous group, and + environment group are either duplicated from the parent for the + new process, or created, or shared. It all is the same that was + done by rfork to adjust resources for the current process when + no RFPROC flag was given (The main difference is that resources + are shared when they are neither cleared nor cloned). Perhaps + some code could be shared and rfork made shorter; nevertheless + the code is simple and easy to follow. + sysproc.c:156 + hang is a flag stating that the process should stop when doing + an exec to give the user a chance to debug it. The child gets + the same flag than the parent. As creating new processes is + usually an rfork plus an exec, it makes sense to propagate the + flag. + sysproc.c:157 + ``permissions'' for the file representing the new process are + the same they were in the parent. + sysproc.c:159,162 + Read the comment! When you do an rfork requesting the creation + of a new process, the parent is given the pid of the child, and + the child appears to return from rfork just like the parent, + but returns zero instead. forkchild sets things up in the child + so that it would appear to be returning from rfork with a + return value of zero. Note that trap (../pc/trap.c:227,230) did + set dbgreg to point to the Ureg saved by the hardware when + rfork was called. + + sysrfork + forkchild() Handcrafts the child kernel stack. + + ../pc/trap.c:772 + forkchild has to be machine dependent because it assumes the + stack layout for the current architecture. + trap.c:777,782 + When the scheduler jumps to the new process, it will jump to + the sched label in p. The author initializes the label so that + the kernel code executing is not sched (which usually sets the + label when the process is leaving the processor), but the first + instruction of forkret. forkret will then return from the rfork + system call in the child as if it had called rfork. The kernel + stack pointer is set to the end of the kernel stack for the new + process, but leaving room for a copy of an Ureg structure and + two extra words. The two extra words are the return PC and the + argument (the Ureg*) of the syscall routine. Yes, for the + syscall routine and not for the forkret routine. More later. + trap.c:784 + cureg points two words after the top of the kernel stack for + the new process, that is where an Ureg is going to be copied. + trap.c:785 + Important!, the ureg passed to forkchild is copied into the + kernel stack for the new process. That Ureg was the one saved + by the hardware when the user called rfork. Therefore, forkret + has its own copy of that processor context. + trap.c:787 + This is where rfork is forced to return zero at the child. The + return value will be taken from the return-value register, + which is ax. ax is set to zero in the Ureg copied for the child + process.

Names for the text file (binary file) and the user named + duplicated. + sysproc.c:183,187 + The comment says it all. The reason is that when a segment gets + shared, permissions on the page table for the memory affected + can change too. Therefore the MMU has to be flushed to drop the + old permissions from cached page table entries. This will + become clear in a following chapter. + sysproc.c:188,189 + Priority (both base and actual) inherited from the parent. + sysproc.c:190 + The child appears to have run at the same processor the parent + was running at. + sysproc.c:191,193 + If the parent is wired to a processor, the child gets wired to + that processor too. procwired wires the process as you saw + before. + sysproc.c:194,195 + All set.

When the scheduler is called, it could elect the child. + sysproc.c:196 + When the current process gets back to the processor after sched + runs other processes, the pid of the child is returned as the + result of the system call. + That was okay for the parent, but what does the child now? + + forkret Appears to return from syscall. + + ../pc/l.s:539 + When the scheduler picks up the child for running, it jumps to + the sched label for the process and forkret starts running. + forkret does exactly what is done after syscall returns from + the call at plan9l.s:43. The only difference is that syscall + was never called by the current process. The stack was set by + forkchild as if syscall was called, so that forkret could + believe in that. + One thing to see here is that forkret is actually assuming that + the process returns from trap and not from syscall; but the + code in forkret and plan9l.s:45,52 is exactly the same, which + means that it would work anyway. Perhaps it would be better to + move the forkret declaration from l.s to plan9l.s:44, since it + is returning via syscall and not via trap. + l.s:540 + throw away the fake Ureg* argument in the stack. + l.s:541,545 + Reload the processor registers and segments from the Ureg saved + in the child kernel stack by forkchild. + l.s:546 + ignore the couple of words in the Ureg above the hardware saved + processor context in the stack. + l.s:547 + Here we go!

The ax register restored + at line :541 was set to zero by forkchild, therefore, rfork + returns zero to the child. + ../pc/trap.c:535,538 + To complete the discussion of rfork, here is my guess about the + reason for the scallnr!=RFORK in trap. + Suppose that the child was setup by forkchild to start running + in trap and not in forkret--probably by copying the kernel + stack for the new process in this hypothetic previous version + of the kernel source. If the system call was rfork (and it was + called by trap), a new process would be created and both + processes would return from the rfork system call back to trap. + If that would be the case, and the RFORK check was removed, + both the parent and the child would check for pending procctls + and pendingnotes. Perhaps the code used variables in the stack + that could cause the child to be posted a note that was really + for the parent. + Regarding the actual code, the only utility I can see for this + check is to avoid posting a note to the child before giving it + a chance to either install its own note handler or issue an + exec system call and be forbidden for parent's faults. In any + case, the child has its notify field as the parent has it. + + NOTE: Is this correct? Or note handler setup code did not work + properly on forks? Or this has something to do with procctl and I'm + missing that? + + Exec + + Now that you know how a new process is created, let's see how it can + execute a new program. It needs to both locate the program to be + executed and execute it. The separation of concerns between rfork + (creating a process) and exec (executing a program) allows a parent to + perform adjustments on the child process before executing its program. + This comes back from the days of UNIX. + + An executable in Plan 9 is any file with the execute permission set. + Unlike other systems, the file name has nothing to do with the fact + that it could be executed. The file must be either a text file or an + a.out file. A text file to be executed usually starts with ``#!'' and + the path of the program to interpret the file; for example, rc scripts + start with ``#!/bin/rc''. a.out files are generated by the Plan 9 + assembler (see a.out(6)), and contain, among other things, the + following items: + * An Exec header, with information about the image of the program + (sizes for segments, etc.). + * The executable code for the text segment. + * The image of the data segment with initialized variables. + +Locating the program + + sysexec() exec system call. Executes a new program. + + ../port/sysproc.c:209 + A process willing to destroy its memory in favor of executing a + brand new program calls exec; this is the entry point for the + system call. + sysproc.c:226,227 + The first argument is a file name, where the executable for the + new program is to be found. So, check that the address is + valid, and get a pointer for it. Remember that the user virtual + addresses are valid, therefore, the pointer supplied by the + user is ok for kernel usage. + sysproc.c:228 + Ignore this by now. To satisfy your curiosity, indir seems to + mean ``indirection''. + sysproc.c:230,234 + tc is the text channel, or the channel pointing to the text + file for the new program. namec resolves the name in the + current name space and returns an open channel checking for + execute permission. The waserror prepares for closing the + channel and re-raising the error if the following code raises + an error. + sysproc.c:235,236 + namec did set up->elem with the file name--without any previous + path component. So now elem contains the name for the text + file. Again, ignore the indir thing; just notice that it is + zero now. + sysproc.c:238,240 + You know this, right? Using the channel type to call the + appropriate read routine to get the Exec header for the text + file. At least two characters wanted. Yes, the Exec header is + more than two characters, but keep on reading. If the error is + raised, you get back to line :231, the channel is closed and + the error re-raised. + sysproc.c:241,243 + Extracting the magic number from the header, as well as the + size of the text segment and the entry point. The Exec header + is defined at /sys/include/a.out.h:2,12. read could get just + two characters and all these fields could be trash. The numbers + just extracted are stored in big-endian order in the Exec + header, l2be is ``little to big endian'', however, that + transformation on a big endian yields a little endian value; + never mind, the fact is that l2be convert those values to a + little endian representation--shouldn't be this a machine + dependent operation? + sysproc.c:224,250 + If the whole exec header was read and the magic number states + that it is indeed an a.out file, it can be executed. The break + would break the loop used to search for the text file, and + execution would continue at line :275 were a.out binaries are + loaded. The error is raised in case the entry point is set + before the start of the text segment for the user plus the size + of the Exec header, or in case it is beyond the text segment + (plus the size of the Exec header). The image in memory will + contain the Exec header and then the text segment, hence the + range--text images look very much like the file. Besides, the + entry point should be within the user portion of the virtual + address space (not with the KZERO bit set). + sysproc.c:252,254 + Not an a.out. It is a file interpreted by another program. + sysproc.c:255 + The exec header is copied into a character array. + sysproc.c:256,257 + If the line does not start with ``#!'', it is not an script, so + don't know what kind of binary it is. Ignore indir once more. + shargs()Builds arguments for shell scripts. + sysproc.c:258 + shargs takes the line array, the number of characters kept at + line, and builds in progarg an argument vector for the program. + If you read lines :441,469 you will see how that is done. Can + you guess why the loop at :447,449? The number of arguments + filled up is kept in n upon shargs return. + sysproc.c:261 + indir is set when the file is to be interpreted by another + program! + sysproc.c:265,266 + shargs filled up progarg according to what follows #!. Now, + consider an rc script named ``/tmp/f'' starting with + ``#!/bin/rc -e -s'', when the file gets execed, /bin/rc should + run with the command line /bin/rc -e -s /tmp/f. shargs would + have filled up progarg for the command line /bin/rc -e -s, but + it knows nothing about the final missing argument. These two + lines at exec are supplying as the final argument, the name of + the file to be interpreted--note that the argument vector must + be null-terminated. + sysproc.c:267,268 + The first parameter in the argument array supplied as the + second argument to exec is no longer valid, so remove it from + the argument array. + sysproc.c:269,270 + The file being executed is not the script, but its interpreter. + The name of the interpreter is at progarg[0]. Besides, the + interpreter should believe that it is named after the script + name, not after the file containing the interpreter code. The + first parameter for the program executed is set as the script + file name, which was elem. + sysproc.c:271,272 + Now let's get back to indir. You see how the channel for the + script file is closed (and the error label popped because we + already closed the channel). The loop will iterate once more + with file set to the file being execed (the interpreter) and + indir set to one (at line :261). + Should the interpreter file on this new iteration be another + ``#!'' file, the test at line :256 would raise an error. The + author does not want an interpreter to be an interpreted file! + That can appear to be a restriction but it is not--interpreters + are usually binary files, and if they are to be scripts, the + can be easily wrapped with a silly binary file that calls the + script. Should the author allow nested interpreters, a loop + could arise because a malicious (or dumb) user could setup two + files to interpret themselves recursively; e.g. file /a starts + with #!/b and file /b starts with #!/a. It's more simple to + forbid nested interpreters than it is to check for looks in the + nested interpreter call. Besides, allowing nested interpreters + would require more complex code in exec. Despite that, the + author wrote sysexec in a way that makes it easier to allow it + to handle nested interpreters. + If the interpreter is a binary and not an interpreted file, the + check for indir at line :235 preserves elem as the script file + name even though it is the interpreter the one being executed, + and the break at line :249 would lead to the code execing an + a.out file. + +Executing the program + + sysexec + + sysproc.c:275,276 + Starting to execute an a.out, be it an interpreter or not. Now + extract the lengths for the data and bss segments. The lengths + for the text segment and the entry point had to be extracted + before to check for illegal entry points. + sysproc.c:277 + t is set to the end of the text segment. That is the first + address of the segment (UTZERO), plus the sizes for the Exec + header, and text segment proper. The +BY2PG-1 and &~(BY2PG-1) + is rounding the computed value to a page boundary. A page can + be either text or data, but not both. + sysproc.c:278 + d set to the end of the data segment, computed by adding the + size of the data segment to the just computed (and rounded) end + of the text segment. + sysproc.c:279,280 + The end of the BSS (b) computed the same way. + sysproc.c:281,282 + Don't trust the exec header. The end of text, data and bss + segments should not invade the high part of the address space, + used for the kernel. The error would jump to line :231, where + the channel is closed, and the error re-raised. + sysproc.c:287 + nbytes counts how many bytes are to be pushed in the user + stack. You already know that the bottom of the stack is used + for a profiling clock. This ``first pass'' counts the number of + bytes to be pushed on the stack. + sysproc.c:288 + No arguments pushed yet. + sysproc.c:289,296 + If exec-ing with an indirection (i.e. an interpreter), the + argument array is the progarg computed by shargs. Count the + bytes for the null-terminated strings in progarg. + sysproc.c:297 + evenaddr seems to fix the passed parameter to start at an even + address. Some busses would raise an alignment error exception + otherwise; but on the PC, evenaddr does nothing. + sysproc.c:298,307 + Besides any argument counted in the case of an interpreter, the + arguments given as the second parameter to exec have to be + accounted for too--note that for interpreters, the first + parameter (the script name) was removed from the argument + array; that is to avoid counting it twice. The calls to + validaddr are ensuring that both argp and the strings kept + there reside at valid user virtual addresses. The call at line + :299 checks the first word (the first page actually) for argp; + when the page offset for the argp address is less than then + size of the word, argp is jumping into the next page, so call + validaddr once more to verify that the next page is still in + place. Calling validaddr every pass in the loop would be a + waste. The number of bytes to be pushed is incremented with the + length for each argument, as reported by vmemchr (plus one for + the final zero). vmemchr is like memchr, which returns the + pointer to the first occurrence of a character (0) in a string + (a); unlike memchr, vmemchr checks that the memory where the + string resides is valid user virtual memory. By subtracting the + start of the array (a), its length is computed. + sysproc.c:308 + the size of the user stack is now known: One pointer per + argument plus a null terminator for argv; plus the actual size + of the arguments, rounded to a multiple of the word size. + sysproc.c:310,315 + The comment says it all. On Intels it can waste a bit of memory + but who cares. The author is still computing the size of the + stack. + sysproc.c:316 + Count the number of pages needed for the initial stack. + sysproc.c:321,322 + Ensure the the user stack does not get too big. TSTKSIZ is the + maximum allowed size for the ``temporary'' user stack being + setup now. + sysproc.c:324,328 + Going to operate on process's segments, qlock it. Note the use + of a QLock (long waiting, maybe), and the use of waserror to + release the lock in case of errors. + sysproc.c:329 + A new stack created. ESEG is an extra segment slot used for + exec. Right know exec could still fail, and you don't want to + loose your user-level stack yet. This stack segment goes from + TSTKTOP-USTKSIZE to TSTKTOP; noticed it is not USTKTOP? The + author does not want to mess up the current user stack because + exec can still fail, therefore, a temporary stack segment is + created right below the user stack. TSTKTOP (../pc/mem.h:54) is + precisely USTKTOP-USTKSIZE. Even though the stack is not at + TSTKTOP, pointers pushed on it have values assuming that it + starts at USTKTOP. This stack is going to move to its proper + location, but later. By the way, I think that the comment that + says ``putting it in kernel virtual'' is a bit confusing, since + the stack is being built at the user portion of the virtual + address space. + sysproc.c:331,350 + setup the stack arguments for the new process. Arguments are + copied appropriately including progarg when indir is one. You + should understand the code. Remember that the pointers pushed + (i.e. :346) assume that the stack is mapped at USTKTOP, and not + at TSTKTOP. + sysproc.c:352 + elem was kept with either the binary file name (indir not set) + or the script name (indir set); copy it as the name for the + process text. + sysproc.c:354,363 + Old segments ``released''. This is a point of no return. Only + segments between SSEG and BSEG are released. That includes the + current user stack (which is not shareable), text (which is + being replaced by exec), data (which is being replaced by exec) + and BSS (also replaced by exec). putseg decrements the + reference counter for the segment and releases resources + (memory, mostly) held by the segment when the counter gets down + to zero. + sysproc.c:364,370 + From the BSS on, only segments marked as ``close on exec'' are + released. Remaining segments are kept. Shared segments created + by the process would lie between BSS and NSEG; so they would be + kept shared between the parent and the child. fdclose()Closes + file descriptors with a matching flag. + sysproc.c:375,377 + File descriptors marked as ``close con exec'' on the fgrp for + the new process are released. fdclose closes all open file + descriptors which happen to have set the flag passed it. In + this case, all open file descriptors marked as CCEXEC would be + closed. + sysproc.c:379,383 + tc is the channel to the text file, attachimage returns an + Image corresponding to that channel. The thing going on is + caching. The Image structure, discussed later in the virtual + memory chapter, is responsible for caching images of text + files. If someone else is executing the program found at the + file pointed to by tc, the memory used to keep the text loaded + will be shared because the Image used would be the same. Don't + worry too much about this, just think that the Image contains a + segment (img->s) used as a cache for the program text. ts is + kept pointing to the text segment and seg[TSEG] is set + accordingly. + The comment states that the image is ``locked'' when returned. + That is because the author is going to update the segment held + by the Image. The text segment may be shared by different + processes and it would make no sense to acquire the seglock on + one of them to operate on the segment. Instead, the Image must + be locked to work on the text segment. + sysproc.c:384,387 + You will know when virtual memory be discussed. Just to record + that all the text should be ``flushed'' because it is now + shared, and also to know where is the text in the image. + sysproc.c:389,398 + A new data segment created and set in place. The Image for the + data segment (the place where memory comes from) corresponds to + the binary file where the text was found, but starting after + the text. You know that a.out files keep both text and data. + sysproc.c:399,400 + The BSS segment created. The ``zero-fill on demand'' means that + pages will be brought in for the segment as needed, they will + be filled to all zeros when brought. + sysproc.c:402,412 + exec passed the point of no return, so there is no problem to + relocate ESEG into its place, SSEG, which is the proper + location for the user stack. Now that the seglock is released + there is no need to jump back to line :325 on errors. The base + address and top of the stack is set, and relocateseg adjusts + the segment so it starts at USTKTOP, where it belongs. The + movement is done by changing the virtual memory address + translations. + sysproc.c:414,419 + Read the comment, you already know about priorities. The + ``device character'' for the root device is ``/'', so the + kernel is checking that the file comes from the root device. If + that is the case, the priority is adjusted accordingly; + otherwise the process keeps the priority it had (probably + inherited from the parent at rfork). + sysproc.c:420,421 + Remove the error label first, so that if the close for the + channel fails, exec would not close it again. + sysproc.c:428,433 + No notes yet, and FPU state initialized. + sysproc.c:434,435 + If hang was set, honor it by by setting procctl to Proc_stopme, + which means that the process will be stopped for debugging + before returning to user level. + sysproc.c:437 + Finally, execregs initializes the user stack pointer and + program counter. + + sysexec + execregs() Initializes user registers so the program starts in its + entry point. + + ../pc/trap.c:706,719 + execregs starts by setting up sp to the actual top of the user + stack, with ssize bytes on it. Then it pushes the number of + arguments to complete the main entry point arguments. As + syscall did set dbgreg to point to the ureg saved by the + hardware, the only thing to be done is to update on it the user + stack pointer and the program counter. The return value for + sysexec is the address of the profiling clock, which might be + used by the user-level library code, but seems to be not + relevant for the kernel. Remember that exec does not return + when successful, so the return value can be only of interest to + the assembler entry point for Plan 9 processes. + + By the way, in case you didn't guess, the loop at lines + sysproc.c:447,449 is to ensure that the first line of the script fits + within the size of an Exec header. Remember that exec read the header + and then copied it to line? If the line is longer than the size of the + header, exec would miss the trailing part of the line, so better fail. + This is a tradeoff for simplicity, as exec could perfectly keep on + reading until a whole line is read. + + Dead processes + + Processes can terminate existence in several ways. First a process can + call exits to terminate itself (see exits(2)). A message can be passed + to exists, which will be passed by the kernel to the parent process + calling wait(2). Thus, the concept of a process hierarchy also helps + in controlling how processes went in their lives. The parent calls + wait and receives reports about its dead children; every child tells + the parent. + + The message passed is more meaningful for humans than the UNIX error + code, and what is actually more important, is portable to different + architectures! The convention is that a null string means ``ok''. + + Another way to (almost) terminate is by faulting, either voluntarily + (see abort(2)) or involuntarily. Faulted processes are kept hanging + around for debugging in a Broken state. That is better than saving a + core file for several reasons: first, no more core files hanging + around in the file system; second, a broken process is still ``alive'' + and can be inspected for more than just data values, the broke(1) rc + script can be used to locate and terminate broken processes. + + Yet another way is by using the proc(3) device ctl file for the + process. A write of kill to that file, terminates the process. This + way works fine over the network, since the file can be used remotely. + +Exiting and aborting + + /sys/src/libc/386/main9.s:1,7 + The entry point for the user process is usually _main. _main is + an assembly stub that calls the C entry point, main, after + doing some work for the profiling clock and the main arguments. + Remember that the return value of exec was the profile clock? + That value was ``returned'' to the new program. + main9.s:9,13 + If main ever returns without calling exits, exits would still + be called with the ``main'' string as the argument. + + sysexits() Terminates the process reporting a reason. + + /sys/src/9/port/sysproc.c:502 + One way or another, sysexits is the entry point called by the + process terminating. + sysproc.c:505 + In case the user error string (the first argument) does not + look fine, this is the string reported. + sysproc.c:509,522 + If no status string was supplied, that is ok. If it was + supplied, copy it to the kernel buffer buf. validaddr and + vmemchr are used to be sure that addresses are valid. If + addresses are not valid, an error is raised and status is set + to inval. + sysproc.c:523,424 + pexit kills the process; the return is to make the compiler + happy--all system calls should return a value. + proc.c:732 + The 1 as a second argument asked pexit to release the process + memory; it is really being killed. + + sysexits + pexit() Terminates the process. + + proc.c:745 + By setting alarm to zero, any alarm is canceled. The Proc may + still be linked into the alarm list. This is not a problem + because if a new process reuses the Proc entry, and it does not + use alarms before expiration of a previous alarm for this Proc, + alarmkproc will find its alarm set to zero and ignore it. If + the new process ever sets an alarm, it will be first removed + from the alarm list. + proc.c:747,759 + All resources cleared while the lock was held. Releasing them + may take some time, so do not hold the lock for more than + needed. + proc.c:761,770 + Now resources are released by calling routines that decrement + their reference counters; if a reference counter gets down to + zero, the resource is released--perhaps causing other + decrements in reference counters for structures used by the + resource; e.g. the fgrp uses channels that are cclosed when the + fgrp goes away. + proc.c:776 + Kernel processes are always there, and the author does not do + housekeeping for them; but user processes have parents and + there is a relationship to be maintained. + proc.c:777,782 + All processes have a parent. You will see what happens to a + process when its parent is not there. Hint: read the panic + message! + proc.c:784,788 + A waserror but in a while loop. Remember that waserror returns + false when first called to set the error label, and then it + returns true when an error jumps back to the waserror? The + effect of the while is to call waserror again when an error + happens--i.e. to restore the error label popped by error. That + means that the process keeps on trying to smalloc a Waitq + structure, no matter what errors happen. But, smalloc provides + guaranteed allocation. What error could be raised by smalloc? + smalloc calls tsleep to wait for free memory if the pool is + exhausted, tsleep calls sleep, and sleep raises an Eintr if the + process is interrupted. So, no matter how many interrupts the + process gets, exits will not be aborted returning to the + process with an Eintr error; exits does not return, ever! + proc.c:790 + readnum prints the number given into the buffer passed + (shouldn't it be ``printnum''?) It returns the number of + characters used to print the number, or zero if it did not fit. + The buffer is wq->w.pid, and the number id up->pid. So, the pid + field in the message for the parent kept (in the Waitq + allocated) is being filled up with the ascii representation of + the pid. + proc.c:791,798 + These calls to readnum are filling up the the wait message for + the parent with times as said in wait(2). TK2MS converts ticks + to milliseconds and the time entry at Treal is used to know for + how long the process had lived. Saw how the message can be + understood at any architecture? Guess why? + proc.c:799,805 + If a non-null (and not empty!) error string was supplied by the + process, it is copied into the error message in the wait + message--note how the message is prefixed with the name for the + text file and the process pid. That is very important when the + parent process is a shell, like rc, to let any human user know + who did die. It is also important if the parent cares about who + died. + proc.c:807,830 + If the parent's pid (p->pid) does not match parentpid, the + parent is not ``associated to the child'' (see rfork) and does + not care about the wait message from this child; if the parent + is broken it does not care either; and if more than 128 wait + messages are queued for the parent, the author thinks that the + parent does not care either. Daemon processes that fork a child + per request, but ``forget'' to call wait would be able to leave + an indeterminate number of wait records behind them but the + 128-check enforces a 128 limit. This is yet another detail + where you can see how the author tries to protect the system + against buggy processes. + To pass the wait message for the caring parent, just queue it + in the parent's waitq (queue of wait records). If the parent + cares, the number of child processes and wait records is + adjusted. The wakeup, awakes the parent in case he is sleeping + waiting for a wait record. By the way, remember that nchild was + incremented in rfork only if RFNOWAIT was not set? + proc.c:833,834 + User processes bookkeeping is complete. This code is executed + for both kernel and user processes. If the memory should not be + released, the caller wants the process to hang around in a + broken state. + + ... + pexit + addbroken() Keep the process in a Broken state. + + proc.c:670,696 + addbroken moves the process to an array of broken processes, + and changes the state to Broken. By calling the scheduler, + addbroken will not return unless the process is set again + ready; that happens when the process is really terminated (e.g. + by a write of kill to its ctl file). Should this happen, + addbroken returns and the remaining code at pexit would + terminate the process. It is nice how the code to terminate the + process is shared in this way for both processes exiting and + processes aborting. When NBROKEN broken processes exist, the + first who broke is terminated to make room for the new broken + process. One thing to note is that too many broken processes + are a waste because they would probably never be debugged. + Perhaps for CPU server kernels it would be better to keep a + broken structure per user using the CPU server, but the author + thinks this suffices. Another thing to note is that the broken + process is terminated just by placing it in the ready + queue--when it runs, pexit will terminate the process. Just + simple. + + ... + pexit + + proc.c:836,844 + Segments released. The process' mind is going. Only when the + last reference to each segment is gone, it is released. Do you + think that these lines would destroy the stack segment? And the + text segment? + Although you are not expected to answer this before the chapter + on virtual memory, what happens if there is an ongoing page + fault on one of the segments released? How can the page fault + handler ensure that the segment will not go away under its + feet? + proc.c:846,849 + By setting pid to zero, no child will leave a wait record + because of the test at line :815. The wakeup is not for this + parent process (which is dying and not in pwait), it would + awake any process waiting in devproc.c:561 for a child to die. + proc.c:851,854 + Now that nobody is linking more wait records, release all wait + records queued--the parent could terminate without calling + wait. + proc.c:856,862 + Awake any debugger waiting for us (e.g. waiting for a note to + be posted for us) and dissociate from the debugger. + proc.c:864,866 + After a couple of locks are taken, the state is set to Moribund + and sched is called. sched will never return because the + process is really destroyed and will not get back to the ready + queue. If a bug makes sched return, panic. Why does the author + acquire these locks here? + proc.c:64,79 + sched calls gotolabel for m->sched, which leads to code in + schedinit. This time, this branch is taken and the process + state is set to Dead. After releasing MMU data structures for + the current process (using the prototype page table for the + current processor afterwards), the process is linked into the + free process list. Releasing MMU data structures and linking + the process in the free queue, requires both palloc and + procalloc locks to be held. However, right now in schedinit, + which one is the current process? There is no process. What if + lock couldn't acquire the lock at the first attempt? What if it + even called sched? That is why the locks are acquired while + there the dying process is still alive enough for requesting a + tas lock. + The kernel stack is kept bound to the Proc (and reused by the + next process using that Proc). After the locks are released, + any other processor could pickup the Proc and its kernel stack + could be reused. This is no problem since the current stack is + the ``scheduler stack'' kept near Mach. Using a scheduler stack + allows the author to step back out of the dying process while + killing it. + proc.c:80,83 + The current process is gone, sched called and it will call + runproc to run another (existing) process. + + In case you didn't notice, processes aborting, generate a fault that + (as you will see) end up calling pexit with an indication not to + release the process memory. + + By the way, it would be nice not to release the process resources + (fgrp et al.) for broken processes (at least when explicitly + requesting so), so that the process could be debugged even looking at + the set of open file descriptors; and perhaps it would be feasible to + fix things up a bit and let the process get ready again. One simple + way to do so would be to move the process into the Broken state before + line :747, and to add control operations to fix up the process state + and set it back to ready. + + I think it's time now for you to look at figure [223]4.12 and see how + a process changes its state. Probably you did draw a scheduling + diagram while you learned how processes are born, get ready, etc. + Compare yours with the one in the figure. For the sake of simplicity, + I have not shown the Scheding state, which is used while the processes + is changing its scheduling state in several places (e.g. from Ready to + Running and from Dead to Ready). + + CAPTION: Figure 4.12: (Simplified) process state transition diagram. + Do not take it verbatim: the Scheding state is missing, Broken + processes appear to go right to Moribund, without passing through + Ready. + + \resizebox{10cm}{!}{\includegraphics{sched.eps}} + +Waiting for children + + syswait() Waits for dead children. + + sysproc.c:528 + syswait is the entry point for wait(2). After checking that the + Waitmsg pointed to by the first argument resides at valid user + addresses, pwait does the work. + + syswait + pwait() Wait for dead children. + + proc.c:883 + pwait receives the Waitmsg to be filled up. + proc.c:888,889 + If the wait queue is being manipulated (a child dying right now + at a different processor?) just give up. Why? seems to be for + avoiding deadlocks between devproc and proc. In any case, the + parent is likely keep on calling wait until he gets the desired + wait record. + + NOTE: is this true? + proc.c:891,894 + Now the lock held. + proc.c:896,901 + If there is no child (dead or alive), abort. + proc.c:903 + sleep until haswaitq; haswaitq returns true if the wait queue + is not nil. Therefore, if there are children in the wait queue, + the process will not even sleep. If all children are alive, the + process sleeps until it gets awaken by a dying process, or by a + note. + proc.c:905,909 + Got a dead child, remove a wait queue entry. + proc.c:911,912 + Nothing else to do, release the lock. + proc.c:914,918 + Return extracted information by copying it to the parameter + passed (if it was not nil), and returning the dead child pid. + + The proc device + + Although process creation is done only with system calls, processes + are represented as files for most other purposes. Read the proc(3) + manual page to learn what files are serviced by the proc driver. Proc + can be mounted over the network to operate on remote processes as if + they were local; not the UNIX's /proc, definitely. Files under + /proc/n/ correspond to views of running processes; e.g. two successive + cats for /proc/n/status would return different file contents, because + the file contents are the status of the process, and the status + changes over time. Reads under /proc/n are used to inspect processes, + and writes under /proc/n are used to change various things on running + processes. + + In the next chapter, you will learn more about file systems in Plan 9, + and will be able to understand better devproc.c, that is where the + proc device implements its file system. However, I think you can + understand most of devproc now. I am going to discuss the code related + to inventing a file hierarchy from the set of processes; but skipping + code related just to the file system, which will be clear after the + chapter on file systems. + +Overview + + devproc.c:10,28 + Several Qid types defined. + devproc.c:54,67 + Here you see how actual Qids are built from the Qid types + defined above and the process numbers. Why does the author do + this? + devproc.c:31,49 + This data structure is a template for the directory serviced + for each process. You can see the file names, the Qid for the + file, the file length and the file mode. + devproc.c:757,776 + This is the Dev structure linked into devtab. The `p' is the + letter name for the driver, and most fields are pointers to + routines used when a channel type corresponds to devproc. + Routines with names starting with dev are default + implementations for channel operations in dev.c. Many of the + routines supplied by proc, relay on generic implementations + that use the procgen routine to iterate through a proc + directory. Let's see some of the routines now. + + open... + procopen() Opens a proc file. + + devproc.c:161 + procopen is the routine used when a file under /proc is being + opened. The file to be open is represented by the c channel. In + Plan 9, opening a file means to check permissions and prepare + the file for I/O. For example, after you walk to + /proc/3/notepg, you have to open it before writing it. + devproc.c:168,169 + The CHDIR bit is set in Qid, therefore, a directory is being + opened; rely on the generic routine for that. + devproc.c:171,176 + The process slot is kept in the Qid; give the slot to proctab + and obtain the Proc for the c channel. Remember that the file + being opened is not a real file, but some aspect of a process. + procopen is locating the process and locking it so that the + process could be inspected without race conditions. + By keeping both the slot and the kind of file in the Qid, the + author knows quickly what kind of processing (and on which + process) should be done given the Qid for the file. + devproc.c:177,179 + The process could have died since the channel was obtained (by + a walk) and the open was requested. If the process died (even + if its Proc was reused by a different process), the PID in Proc + will not match the PID in the Qid. + devproc.c:181 + openmode checks omode for invalid bits. + devproc.c:183 + Each file under /proc/n has a type encoded in the Qid (see + lines :10,28). + devproc.c:184,191 + The text file for the process is the one being opened + (/proc/n/text). Only opening for reading is allowed, since the + text is being used for executing the process. proctext is the + routine doing the job. proctext()Gets the channel for the + process text. + devproc.c:785,797 + Check that the process text is still there and get a reference + to the Image for the process text segment. + devproc.c:805,807 + The image contains a channel to be used for accessing its file. + devproc.c:809,812 + Increment the reference counter for the channel (someone opened + it), and check that channel is still opened for reading. When + the process is still there, the code is not assuming that the + image is there; and when the image is there, the code does not + assume that the channel is set up for reading. Why? Hint: + processes are living things. + devproc.c:820 + Now got a channel for reading the file for the process text + segment image. It has been incref'ed, and will be the channel + resulting from procopen. + devproc.c:193,200 + For these files (/proc/n/proc,etc.) nothing has to be done but + to check that the open is for reading--processing continues + after the switch. + devproc.c:202,210 + Nothing done; can be opened for read or for write. + devproc.c:212,216 + For /proc/n/ns, mode has to be read and temporary storage for + walking the mount table is allocated. + devproc.c:218,226 + For /proc/n/notepg, only writes are allowed, and not for the + first process group (boot). The id of the process group and the + noteid for the process are kept as a Qid in the channel. + devproc.c:228,231 + Defense against bugs; no other Qid types known. + devproc.c:233,246 + After checking that the process is still there, the generic + devopen routine is called. devopen uses procgen to iterate + through the proc/n/ directory searching for a file matching the + channel supplied by the user (i.e. the file being opened, like, + /proc/n/ns). Once found, devopen checks permissions and either + raises an error or returns the channel. + + wstat... + procwstat() Updates attributes of a proc file. + + devproc.c:250,256 + procwstat is used to modify file attributes, including + permissions. No wstat is permitted on directories. + devproc.c:268,269 + Only the user who started the process, and eve can change + attributes in proc files. + devproc.c:271 + convM2D converts the machine independent representation of file + attributes (given by the caller) into a Dir structure, more + amenable for processing. The file could be wstat'ed from a + different machine with a different architecture. + devproc.c:272,279 + If the user in the Dir structure (to be written) is not the + owner of the process, a chown is being done. Only eve is + allowed to do such thing. + devproc.c:280 + Honor a chmod in the file. + + close... + procclose() No more I/O on a proc file. + + devproc.c:337,342 + The temporary storage allocated in procopen is released when + the file is closed. + +Reading under /proc + + read... + procread() Reads from a proc file. + + devproc.c:363,364 + procread services reads under /proc files. It corresponds to a + call read(f,va,n) with the file offset set to off. + devproc.c:378,379 + Use the generic routine for reading directory entries. + devproc.c:381,383 + The process could have died since the open was done. + devproc.c:386,414 + /proc/n/mem represents the process memory. Reading is achieved + by doing a memmove to copy the memory being read into the + buffer transferred to the caller of read. The mem file + represents virtual memory: offset 0 is virtual address 0. Not + all addresses are valid. + devproc.c:387,389 + Addresses before KZERO or within the user stack are read + with procctlmemio, which checks that addresses are valid + and lie within process' segments. Perhaps some time ago + the user stack was within the kernel portion of the + address space; right now, the first part of the ``or'' at + :387,388 is true whenever the second part is true. + devproc.c:391,401 + Addresses between KZERO and end correspond to kernel + addresses and are read by a direct memmove without further + checks. + devproc.c:402,413 + Remaining addresses correspond to memory found at the two + memory banks in conf--also read with memmove by the grace + of the direct map between physical and virtual memory. + Remember that addresses in conf were updated to be kernel + virtual addresses--although early when booting they were + physical addresses instead. + If you trace the kernel execution after the open of + /proc/n/mem, you will see how permissions are checked using the + mode kept in the Proc structure for the process. The author is + permissive in allowing any user with permissions to read kernel + memory (even though he protects the memory used to keep user + keys, all memory allocated from xalloc can be read). However, + this permissiveness is good to make it easier to debug and + inspect the kernel state. + devproc.c:415,427 + Profiling is not discussed now, but see proc(3). + devproc.c:428,451 + Copy to the user buffer the text for the first note posted for + the process, and decrement the number of notes. You can see how + posted notes can be read/canceled by reading this file. + devproc.c:452,458 + The Proc structure is read. Useful to debug the kernel: No need + to put more prints nor to attach a debugger just to see a value + in Proc, just read it. + devproc.c:460,483 + Useful!, dbgreg pointed to the saved Ureg while the process was + switched out. A read here returns the user context. The code + below regread: simply copies the memory read from the Ureg + pointed by rptr. The kregs file corresponds to the kernel + context. When the process in on its way to be switched out, + there is an Ureg saved when last entering the kernel which + holds the user register set; but then the process is really + being switched out, there is a label set by the scheduler + before jumping to other process' kernel label: setkernur sets + in the ``kernel Ureg'' the PC and SP saved in the process + scheduling label. There is no kernel Ureg, although users are + told so. Remaining registers in the ``kernel Ureg'' are + reported as zero. + devproc.c:485,518 + The status file is invented to contain the name for the text + file (:495), the owner of the process (:496) and the process + state (as kept in psstate). If pssate is not set, the process + state name is obtained by translating the process scheduling + state state to a printable representation. Besides, various + times and the size for the process are reported as said in the + proc(3) manual page. To compute the size, the lengths (top + minus base) for the various segments are accounted for. NAMELEN + and NUMSIZE are used to pad the various pieces of status at + fixed positions in the ``file''. That can simplify a lot the + code to read a particular field of the status file. + devproc.c:520,539 + segment contains a printable representation of the segments for + the process. The segment array is iterated to obtain segment + names, types, and boundaries. + devproc.c:541,575 + The contents of the wait file are the next wait message from a + died process. The code uses the waitq as you saw before for + wait(2). The read on /proc/n/wait would block until a child + dies. If you see line :554, the read would fail if there is no + children and the read of /proc/n/wait is being done by the + process /proc/n/. That is, the parent can use read to block + waiting for a dead child; other (unrelated) process can read + this file to cause a ``wait'' for the child. Perhaps the wait + system call could be removed in favor of reading /proc/n/wait. + devproc.c:577,611 + Not to be discussed now, but the code synthesizes the text + corresponding to commands to reproduce the name space for the + process. That text can be fed to a shell to recreate the name + space even at a different machine. + devproc.c:613,616 + noteid is simple. procfds is generating a text representation + of open file descriptors. + + read... + procread + procfds() Reads a proc file descriptors file. + + devproc.c:286,335 + The Fgrp for the process is iterated and for each open file + descriptor, the channel is inspected to obtain the open mode, + device type, Qid, file offset, etc. + +Writing under /proc + + write... + procwrite() Writes a proc file. + + devproc.c:661 + procwrite is analogous to procread, but does a write instead. + The write is for file referenced by c, and corresponds to a + write(f,va,n) when file offset is off. + devproc.c:669,670 + No writes on directories. + devproc.c:677,680 + A write to notepg would post a note to the process group. You + saw how pgrpnote did that. Remember that procopen set pgrpid in + c to contain the noteid? When the user opened the file, the + notepg file represented a concrete note group. Should the + process change its note group in the mean time, the file still + points to the old note group. Besides, the process is not + checked for death before pgrpnote is called. So, imagine you + want to kill all processes in a process group by posting a note + to the group. Imagine that you open the notepg file, and then + the process starts dying voluntarily; by using the saved + noteid, the file would still cause a note post to remaining + processes in the note group. + devproc.c:691,697 + A write to mem is used to modify process memory. A debugger can + use this file to update variables in the debugged process. The + process should be stopped though--because it would be + unpredictable what could happen if memory could be updated + while the process is running. procctlmemio is used to operate + on process memory, as happened in procread. If you look at the + last parameter it was 1 in procread and it is 0 in procwrite; + it is deciding what to do: read or write. + devproc.c:698,706 + A write to regs updates the saved registers for the process. A + debugger can use this to update the process PC, SP, etc. + (dbgreg points to the saved Ureg for the process). + setregisters()Updates the process Ureg. + ../pc/trap.c:734,747 + setregisters copies the supplied registers into the Ureg for + the process. Both flags and code and stack segments are ensured + to be valid ones. Otherwise the user could cause a system crash + or break system security. + ../port/devproc.c:708,714 + The same for FPU registers. In this case, the user can update + all of the FPU context and no machine dependent routine is + needed to ensure that a valid state remains. If the user is + writing a wrong state, he would just harm himself. + devproc.c:716,718 + A write to ctl can be used to perform control operations on the + process. + + write... + procwrite + procctlreq() Writes a procctl request. + + devproc.c:873,881 + procctlreq does the job after copying the request string to a + kernel buffer. + devproc.c:883,884 + A write of ``stop'' to ctl leads to a call to procstopwait with + the last parameter set to Proc_stopme. procstopwait()Wais for a + process to stop. + devproc.c:828,835 + procstopwait attaches the current process (up) as the debugger + for the process whose ctl file is being written. To setup a + debugger for process p, the pdbg field of p is set pointing to + the debugger process, and procctl in p is set to be the process + control operation. The author wrote things so that the control + operation is known to p, and it will honor it if needed. If the + pdbg field of the process' Proc was set, there was already a + debugger and the call fails. If the process was already + stopped, the write of ctl results in a non-operation. + The write of ctl can be done through the network, and in that + case, the debugger would be running at a different machine. So, + who is the debugger process? The write request would have been + sent through the network, but there is a (file system server) + process in the node of p doing the actual write to the ctl + file. That process would be setup as the debugger in the Proc + structure. For the kernel, it does not matter if that is the + real debugger or a remote delegate for the debugger. + devproc.c:838 + The (debugger) process psstate is set to Stopwait. sleep will + make the process wait. The p process state can still be Running + or Ready, so the scheduler can elect it for running. When the + to-be-debugged process runs again because the scheduler elects + it, it will reach soon either the end of trap or the end of + syscall in trap.c. + + trap + notify + procctl() Checks for process control operations. + + ../pc/trap.c:310,313 + If it is trap the first one to notice, it would call notify + when noticing that procctl is set. + trap.c:535,538 + syscall would do the same. + trap.c:552,553 + notify checks for notes, but it calls proctl too-when it sees + that a control request is pending. + ../port/proc.c:1096,1098 + If the control operation is to terminate the process because it + consumed too much physical memory, do so. The process is + killing itself upon request. + proc.c:1100,1102 + If the process is being killed, do so. + proc.c:1104,1107 + This is for tracing processes, you can ignore it now; although + you can see how it does the same of Proc_stopme when the + process has pending notes. + proc.c:1109,1126 + The process stops itself voluntarily. The ``ps'' state is + updated to reflect that the process already stopped. The + scheduling state (p->state) is set to Stopped. The call to the + scheduler switches to a different process and the debugged one + will not run again until it is set Ready (by the debugger). The + local state is used to resume the process in the state it was + before being stopped, because it could be a different thing + each time the process is stopped. Before discussing the wakeup + call, note that interrupts were disabled since notify was + called. That makes sense since it messes up the user stack and + besides it can stop the process via procctl. + proc.c:1116,1119 + If there was a debugger waiting for the process to stop, wake + it up. The debugger expects the write to /proc/n/ctl not to + return before the process is stopped. + devproc.c:844 + So the debugger sleeps until the process is stopped. If the + wakeup runs before the sleep, the procstopped function will + notice and the debugger will not even sleep. Otherwise the + debugger sleeps until the process stops itself and notifies the + debugger. + proc.c:1118 + One more thing, pdbg is set to nil when the operation is done. + pdbg is used to let p know who is its debugger (so it could + awake it, etc.), but as soon as p does not need to know who is + its debugger, the ``connection'' is reset. pdbg acts as a lock + in that if a debugger is already (waiting for) stopping the + process, no other debugger would be allowed to do so. Once the + process is stopped, a different debugger process can operate on + the process. + devproc.c:847,848 + The debugged process could die due to a note post or a control + operation. + + write... + procwrite + procctlreq + + devproc.c:885,900 + Back to procctlreq, a write to ctl with a ``kill'' string would + kill the process. Should the process be broken (did fault), + unbreak sets it ready again. unbreak()Terminates a broken + process. + proc.c:699,713 + It does so by scanning the broken process array and setting as + Ready the one passed as a parameter--the array is updated to + reflect the deallocated entry. + Although it may look silly to scan the array instead of using + p, remember that at most NBROKEN processes are kept broken. In + general, processes must be either running, linked into a ready + queue, or linked into the data structure that prevents the + process from being ready. In this case, broken does the job. + devproc.c:891,895 + Should the process be stopped, it is killed by the system. The + Proc_exitme control operation will be handled later by procctl. + The process is set back into Ready state so it could run and + kill itself. + devproc.c:896,899 + In any other state, the process will either be Ready, or get + back to Ready if it was sleeping or doing a rendezvous. So just + post the note and setup the control operation. + devproc.c:901,906 + hang requests that the process stops when doing an exec. Just + update the flag accordingly. It is honored by exec, which uses + the Proc_stopme control operation to stop the process doing the + exec. + devproc.c:908,909 + A write of ``waitstop'' uses procstopwait again to stop the + process. Unlike the previous usage, ctl is now zero, which + means that no control operation is posted (:833,834). So, the + writer of ctl would sleep until the process is stopped, but it + does not stop the process: it waits until the process stops. + For example, a debugger process may write ``hang'' to ctl and + then waitstop, to wait until the debugged process does an exec. + devproc.c:911,917 + A write of ``startstop'' resumes an stopped process (sets it + ready) and then waits until the process stops. Although + procstopwait would set procctl to Proc_traceme, it is set by + hand before allowing the process to run; otherwise the process + could be free running before honoring the Proc_traceme + operation. + proc.c:1104,1107 + The Proc_traceme operation is handled by the started process + like a stop one, but only when the started process has a note + posted. For instance, a debugger may set a breakpoint and let + the process run until it reaches the breakpoint or faults. + Whenever that happens, procctl would not return at line :1106 + because there are posted notes, and the process will stop after + awaking the debugger process. + devproc.c:919,923 + Just set ready an stopped process. + devproc.c:925,936 + procctlfgrp closes all open file descriptors. I don't know what + this control operation is really for, but it could be useful if + other control operations allowed file redirection to be done by + means of proc(3). + devproc.c:938,949 + A write of ``pri N'' to ctl would set a new base priority for + the process. Only eve is allowed to raise priority this way--it + is her machine, isn't it? Can you see the difference between + the ``root'' user on UNIX and ``eve'' in Plan 9? + devproc.c:951,956 + To wire a process to a processor number. You already saw how + procwired does it. + devproc.c:958,968 + A write of ``profile'' to ctl is clearing the profile + information, which hangs from the text segment profile field. + +A system call? A file operation? Or what? + + Let's look briefly at how the user C library implements some services + using the system calls and system services that you now know. I hope + you will be reading more of that library as you learn how the kernel + works. + + abort() Aborts execution. + + /sys/src/libc/9sys/abort.c + Just crosses a null pointer. The process gets a page fault and + enters the Broken state. + + fork() Creates a new process. + + fork.c + Just calls rfork asking for a new process, with a copy of the + file descriptor and rendezvous groups. + + postnote() Posts a note. + + postnote.c + Writes to /proc/n/note or to /proc/n/notepg. + + getenv() Get the value of an environment variable. + + getenv.c + Just read the file ``/env/name''. + + getpid() Gets the process it. + + getpid.c + Just read the file ``#c/pid''--see cons(3); more on the next + chapter. + + Can you see how even most of the user utility functions are actually + using file operations? + + Files + + File systems are central to Plan 9. Remember that the key point is + that everything is a file and files can be accessed over the network. + In section [224]3.11, ``Files and Channels'', you already learned a + bit about files and channels. You should reread that section if you + forgot it and then continue with this chapter. + + In this chapter you are going to read the implementation of the + various system calls related to files, including bind, chdir, close, + seek, dup, open, read, create, fd2path, remove, and wstat. Besides, as + an example of a file system, you are going to revisit kernel devices + (e.g. pipe), looking at the generic routines provided in dev.c. + Finally, the device translating calls to file procedures into RPCs, + mnt, is also discussed in this chapter. + + During this chapter, you will be reading these files: + * Files at /sys/src/9/port: + + sysfile.c + File system calls. + + chan.c + Channels. + + cleanname.c + Name cleanup. + + portdat.h + Portable data structures. + + pgrp.c + Name spaces. + + dev.c + Generic device routines. + + devpipe.c + Pipe device driver. + + devmnt.c + Mount driver (remote files). + + cache.c + Caching remote files. + + qio.c + Queue based I/O. + + ...and several other ones used as examples. + + Files for users + + Users operate on files using the system calls provided at sysfile.c. + As you already know, such system calls are serviced by using channel + operations. Let's describe now how such system calls work, without + looking too much into the channels. I hope you get a better image of + what is going on after seeing how your system calls are translated + into channel operations. See open(2), dup(2), and close(2) manual + pages. + + sysopen() Entry point for the open system call. Prepares a file for + I/O. + + /sys/src/9/port/sysfile.c:221 + Users operate on files by obtaining file descriptors using the + open (also create) system call. sysopen is the entry point for + open. + openmode()Checks the open mode for a file. + sysfile.c:226 + openmode is called with the second argument. It does a cleanup + of the omode parameter for open and returns a clean omode. In + this case, the cleaned mode (the return value) is not being + used. The author does this call to let openmode raise an error + in case the open mode is not valid. + sysfile.c:227,231 + Cleanup the channel for the file being opened on errors. + sysfile.c:232,233 + namec opens the file and returns a channel for the file name + given. It resolves the name in the current name space; namec is + discussed below. + sysfile.c:234,236 + A new file descriptor allocated to the new channel. + sysfile.c:237,238 + The descriptor points to the channel used. open is done. + + sysopen + newfd() Installs a new file descriptor for the given channel. + + sysfile.c:46,65 + The Fgrp contains an array of pointers to channels. File + descriptors are simply indexes into this array. For example, if + file descriptor 3 is open, fd[3] would point to the channel for + the file. After locking fgrp, the array of pointers to channels + is searched for a nil entry. The first entry unused (:54) is + selected. Lines :56,59 allocate new entries in case all entries + in the array are being used. maxfd records the end of the used + part of the array, and the new allocated file descriptor is set + to point to c at line :62. + + sysopen + newfd + growfd() Resizes the file descriptor set. + + sysfile.c:13,43 + When the descriptor array is exhausted, growfd resizes it, + DELTAFD new entries at a time. The routine does nothing if the + array is already big enough to hold the descriptor desired + (fd); it can be used just to check that f is big enough (nfd is + the number of entries, used or not, in the array). The array + will never contain more than 100 entries going from 0 to 99 . A + good reason to limit the number of file descriptors to 100 is + that nobody could allocate a big amount of file descriptors to + exhaust kernel memory. Another good reason is that this limit + can convince users to close unused file descriptors, which + would also release resources on the file servers involved. + Lines :27,31 are double checking that the number of allocated + descriptors is kept under a reasonable value, for the same + reason. Note also the use of malloc, and not smalloc. If no + more memory is available, the open will fail, and the process + will not sleep waiting for memory. + + sysdup() dup(2) entry point. Duplicates a file descriptor. + + sysfile.c:180 + sysdup is used to duplicate a file descriptor. After dup, two + file descriptors point to the same channel. + sysfile.c:189,190 + fdtochan returns a reference to the channel given the file + descriptor. c holds the channel for the file descriptor being + duplicated, and fd holds the file descriptor number where the + user wants to place the duplicate. + sysfile.c:191,205 + The user specified where to place the duplicate. growfd ensures + that the entry for the descriptor exists in the array. maxfd + has to be updated in case the new fd is the biggest one. + Finally, the channel is linked into the descriptor entry. The + dance with oc is to close the previous channel in case the + ``duplicate descriptor'' was already opened. The channel c has + now another reference (at fd). + Can you find out where is the incref for the channel? + + ... + fdtochan() Gets the Chan for a file descriptor. + + sysfile.c:68 + fdtochan is used wherever the kernel wants the channel given a + file descriptor specified by the user. + sysfile.c:77,80 + Has the file descriptor a channel? nfd is checked before fd[fd] + to be sure that the entry exists. + sysfile.c:81,82 + If the caller of fdtochan said iref, a new reference is added. + This is where the reference was added for the duplicated + channel in sysdup. + The reference is added while f is locked, so that the channel + does not disappear even if someone else is releasing the Fgrp. + sysfile.c:85,89 + Ignore this by now. + sysfile.c:91,104 + If the caller gave a valid mode to specify that the channel is + going to be used according to mode, check permissions. If mode + is -1, or if the channel mode allows everything, no check is + done (the kernel can pass -1 to fdtochan to request the channel + no matter what is going to be used for). Otherwise, the checks + ensure that a read only channel is not used to truncate a file + and that whatever be mode (read or write), the channel has the + bits on. + + syscreate() create(2) entry point. Creates a file and opens it. + + sysfile.c:735,753 + create creates a new file and returns an open file descriptor + for it. It is similar to open, but note how Acreate (and not + Aopen) is given to namec; and how the last argument of namec + specifies the permissions for the new file. Besides resolving + the path given by the user, namec would create the file and + return a new channel for it. Probably it would be good to use a + single system call for both open and create--even though users + could still have to different routines to prevent accidents. + + sysremove() remove(2) entry point. Removes a file. + + sysfile.c:755,776 + remove removes a file (be it a file or a directory). It uses + namec to get a channel for the file, and then it calls the + device specific remove function, which removes the file. + Removing a directory does not require that the directory be + empty, it depends on what the file server implementing the + directory wants to do (e.g. see upas/fs in mail(1)). + + sysclose() close(2) entry point. Closes a file descriptor. + + sysfile.c:271,277 + Users close their file descriptors using close(2). sysclose is + the entry point for that. fdtochan is called, but the channel + returned is not used. If the file descriptor is not valid, + fdtochan will raise an error and sysclose would be done. + Otherwise, fdclose is called to close the open file descriptor. + + sysclose + fdclose() Closes a file descriptor with the matching flag. + + sysfile.c:242 + fdclose closes fd. + sysfile.c:248,254 + First, the channel (c) for the file descriptor is obtained. + After fdtochan and before line :248 another process could have + closed the file descriptor, so c has to be checked to be still + there. The call to fdtochan not only checked that the file + descriptor was open, it also checked that the entry in the + array was allocated, so the author can index on it safely--the + array can grow but it does not shrink. + sysfile.c:255,260 + The flag given to fdclose is checked against the channel flags. + If the flag is not set in the channel, the routine + returns--without closing the descriptor! + That is useful to close only those descriptors that have a flag + set. Saw how the author writes routines that can be used in + more than one way? Did you read ``The Practice of + Programming''? + sysfile.c:261,267 + The first line closes the descriptor, the last line drops the + reference to the channel (which is actually ``closed'' if this + was the only reference for it). Besides, if the descriptor + closed is the biggest one, maxfd is updated to mark the end of + the used part in the file descriptor array. + + But for namec and cclose you already know how file descriptors are + added and removed from the process Fgrp. You also know how are new + Fgrps allocated, duplicated, and deleted when processes are created + and deleted. So, what remains for you to understand what the user sees + of the file system (names and descriptors) is to discuss name spaces. + + Name spaces + + In Plan 9, every process has a name space. Well, every process group + has a name space. Usually, processes sharing a ``session'' share their + name space. For instance, every rio window starts usually with a new + name space, which is a copy of the name space for the process that + started the window. + + The name space is simply a mapping from names to files (actually, from + names to channels to files) that can be adjusted to alter the set of + existing mappings. Name spaces are implemented in + /sys/src/9/port/pgrp.c (because each process group has its own name + space) with tight cooperation from the implementation of channels in + chan.c. To understand name spaces, it is crucial to remember that + every Proc has a Pgrp (name space), as well as a slash channel (root + directory) and a dot channel (current directory). To understand the + implementation of name spaces, I think it is better to see how are + names resolved; then you will understand better the code used to + customize the name spaces. + + As you will see through this section, name spaces can be customized by + using mount(2) and bind(2) to add new entries. Figure [225]5.1 shows + an example of this. You should read the paper ``The Use of Name Spaces + in Plan 9'' [[226]12] from volume 2 of the manual if you are confused. + + CAPTION: Figure 5.1: Name spaces for a couple of processes. Note how + they differ. Each name space has in /bin appropriate binaries for the + architecture used. Besides, the file used for the ethernet device + seems to come from a different machine. + +Path resolution + + namec() Get the channel for a given file name. + + chan.c:630 + namec translates a name into a channel, using the current name + space. It receives an access mode that shows what will be done + with the file (e.g. create it, open it, etc.) as well as an + open mode that specifies whether the caller is going to open + the file for reading, writing, etc. Perm is used to initialize + permissions for files being created. + chan.c:641,642 + namec is called with paths that come from user code; don't + trust them and check that they are at least a non-empty string. + If the caller of namec ``consumed'' all the path, there is no + such file. + chan.c:644,651 + The (virtual) address is not bigger than KZERO, which means + that it is an user-supplied path (not a kernel supplied one). + So, verify that the memory from name to the end of the string + is valid; note how BY2PG is used to do only one check per page + (perhaps this could be embedded into vmemchr?). + chan.c:653,658 + In cname, the author keeps the name for the file pointed to by + channel; release it on errors. You will understand soon the + reason for keeping names on channels. Can you guess it now? + Hint: consider how symbolic links mix with cd on UNIX. + chan.c:660,663 + Names are resolved differently depending on the first character + of the path supplied. The switch is just selecting the starting + point for resolving the name. + Names starting with / are resolved within the pgrp, but + starting at slash; names starting with # are resolved within + the kernel driver name space (they are kind of absolute names + for kernel devices); everything else is resolved starting at + dot. Once the starting point is selected, a name can be + resolved by iteration, resolving one path component at a time. + Lines :660,726 are setting up things so that lines :728,732 + could iterate to resolve the entire path. But how are things + set up? + Callers of namec usually want to know what is the name (without + any previous path; just the file name) for the file just + resolved; e.g. when executing a new program, up->text is set + with the file name (ls) for the file (/bin/ls) being executed. + The author sets elem pointing to the elem field of the current + Proc. As each path component is resolved, elem is updated to + contain the path component. So, the caller of namec can later + use up->elem to recover the file name. + The author sets mntok to reflect whether a mount operation is + allowed in the file name being resolved or not; by default, it + is allowed. More on that later. + isdot is set whenever the path being resolved corresponds to + the current directory. By default, assume it does not. + chan.c:664,665 + Resolving an absolute path (starts with ``/''). newcname + creates a channel name from a string; so cname is set to keep + the given path. + newcname()Creates a channel name. + chan.c:108,122 + A Cname is used to share names among channels with the same + name. It is reference counted. The actual memory allocated is + CNAMESLOP (20) bytes more than needed to hold the path. That + seems to be to permit changes in the name that increase the + path slightly. The ncname counter is used to keep track of how + many channel names there are; If the author sees that the + number of names is close to the number of channels, there is no + point on sharing channel names. The path length is kept within + Cname. Although it could be recomputed by calling strlen, the + author prefers to call strlen just once, and reuse the computed + length whenever it is needed. + chan.c:666 + So, what follows the ``/''? + skipslash()Advances a name past the prefix slash (if any). + chan.c:862,872 + skipslash returns a pointer past the /. The path could be + //xxx, and skipslash would skip all the adjacent slashes. Users + seldom write //, but programs do; just define a variable v1 to + be /a/b/c/, and then add a relative path v2 of the form x/y: + you get /a/b/c//x/y. The system should cope with that. Lines + :867,870 remove any ``.'' component, so that file servers do + not see unnecessary ``.'' names. The system is replacing paths + like ``/./a'',``./a'', and ``/a/.'', with ``/a'',``a'', and + ``/a'' respectively. By understanding ``.'' here, this code + does not need to be duplicated at every file server in the + system, and what is better, the meaning of ``.'' can be kept + consistent across file servers. + I lied a bit, file servers can still see ``.'' as a path. Keep + on reading. + chan.c:667 + Iteration to resolve an absolute path should start at slash, so + get a clone of the slash channel for the current process. A + clone is needed because the iteration used to resolve the path + will ``move'' (actually, walk) the channel to point to each + file/directory along the path name. If the author used + up->slash to walk, the root directory for the process would + change. + After this line, cname is the entire absolute path, name points + to the first component name (after the slash, once any dot has + been removed), and c is a channel pointing to the root + directory for the process. Besides, mntok and isdot are set + appropriately. Although elem has not been set, nextelem will + take care of that later. + chan.c:669 + The name is referring to a kernel device path (e.g. ``#SsdC0'' + to specify the disk sdC0 from the sd device). Kernel device + paths allow you to use devices even though you may have an + empty name space (Remember the implementation of the getpid + function in the C library?) + chan.c:670,679 + As with absolute paths, the channel name is the supplied name. + Mounts were allowed for absolute paths, but not for kernel + device paths. The author wants kernel paths to remain the same, + so mntok is set to zero. Besides, elem is set to contain both + the initial ``#'' and whatever follows until the next slash. + The n<2 check would copy the slash in``#/'', which is the name + for the root device's root directory. So, elem is set to + contain the file name. + chan.c:680,697 + When you use a kernel device path, you are actually + ``attaching'' to (mounting) the file tree serviced by the + kernel device to your name space. Once it is attached, you can + resolve path components within the device's file tree. + Lines :692,695 are extracting the first ``rune'' (e.g. + character for Spanish, but something different for a Japanese) + and looking if it is an ``M'' (utfrune is an strchr for runes). + If it is an ``M'', the path is ``#M'', which corresponds to a + mount driver path (see mnt(3)). The mount driver is the one + issuing RPCs for remote files when you perform a file operation + on them. If users could attach to mount driver paths, they + could bypass file permissions. Imagine that a server checks + credentials from a client when the server file system is + attached to the client name space. Once the client has been + allowed access, another process could try to ``borrow'' some + files serviced by the mount driver on behalf of the previous + process. By denying attaches to mount driver path names, the + only way to get files from the mount driver is by attaching to + (and authenticating with) a remote file server. + Lines :696,697 just check that the Pgrp does not have the + noattach attribute set, which would prevent attachments. This + flag can be used to prevent a process from acquiring more files + than found on its name space. If you don't trust a program too + much, you can build a name space where the program cannot hurt + anybody else, and set the noattach flag. These lines forbid + attachments when noattach is set and the device is any of + ``#|'', ``#d'', ``#e'', ``#c'', or ``#p''; see the comment to + learn which devices they are. The comment says that it is okay + to allow attachments on these devices (i.e. if r is contained + in ``|decp'', noattach should be ignored). However, that would + need a not ('!') before utfrune. I think that the comment is + right, and the if condition is missing a ``not''. + chan.c:698,700 + r holds the first character after the '#'. That character + identifies the kernel device. devno returns an index into + devtab for the given device character. The 1, is to tell devno + that it is the user the one specifying a device name; it is + okay if the user is mistaken: the device may not exist. If a 0 + was given, devno would panic if the device is missing--that + would be a kernel bug. + chan.c:702 + The initial channel to resolve a kernel device path is the + channel obtained by ``attaching'' to the device file tree. That + channel points to the root file for the device. c is setup + properly now. The channel does not need to be cloned because it + is a brand new channel. + chan.c:703 + Once the initial name is processed (the device name), advance + to the next one; as the author did after processing the ``/'' + for absolute paths. + chan.c:705,707 + Must be a relative path. So, the name for the channel is the + name for the current directory followed by the relative path + supplied by the user. up->dot->name->s is the C string in the + Cname for the dot directory of the current process. Once cname + has a Cname built from the current directory name, addelem + adds, as a suffix, the relative path. + addelem()Adds a suffix to a name. + chan.c:137,148 + If the name is shared between several channels, make a new copy + so that adding a suffix to the name will not change the name of + other channels using the shared copy. For instance, when a + channel is cloned, the name is shared among the clones; if a + clone changes its name (e.g. because of a walk), other clones + should be kept untouched. + chan.c:150,158 + More space is allocated to hold the suffix (s) and the small + extra space. + chan.c:159,160 + The new name is prefix+/+suffix, unless prefix was really + ``prefix/'' or suffix was ``/suffix''. + chan.c:708,711 + The starting point to resolve the path is dot, get a clone of + the dot channel in c--the clone is needed for the same reasons + it was needed for absolute paths. The call to skipslash would + simplify things like ./x and .//x down to x. If name is the + empty string after simplifying the path, name referred to the + current directory, so the author sets isdot. + When isdot is set, there are no further elems in the name; this + case is handled as a special case by the code following. + chan.c:714,717 + Starting to walk on the channel, close it on failures. + chan.c:719 + nextelem obtains the next ``component'' name in the remaining + path name, placing it in elem and advancing name past the + element; the advanced name is returned, hence the assignment. + nextelem()Get the next element from the name. + chan.c:903,926 + nextelem is called after skipslash, so there is a bug if the + first character is a slash. If there are no more slashes, the + whole name is the next component name. The loop copies the + component name to elem (up->elem), one rune at a time. isfrog + contains characters that cannot appear as a component name. + Looks like Rob Pike decided to try allowing blanks in component + names. After the element name has been obtained, skipslash does + more ``dot'' and ``slash'' cleanup and advances to the next + component name. + For paths like ``/'' and ``.'', nextelem would set elem to be + the empty string and it would advance name up to the end. + chan.c:721,726 + mount is discussed later. + chan.c:728,732 + The heart of path name lookup. For each component, walk updates + the channel to refer to the next directory/file in the path. + nextelem advances the name for the next component (and cleans + it up), and walk updates the channel (receives a pointer to + it). + You now see that because the channel moves down the path, slash + and dot had to be cloned. + When the loop finishes, the name has been resolved, but for the + last component! In /x/y/z, c would then correspond to /x/y, and + elem would be z; name would be an empty string after nextelem + extracted z to elem. + It is important to stop before the last component because it + could be that it is a file to be created, and it would make no + sense to walk to it. When the path is ``.'' or ``/'', the whole + path was resolved when looking up the initial directory for the + iteration. In this special case, the loop does not execute + because name was already exhausted. + chan.c:734 + How to resolve the last component depends on what is the + channel for. That is why amode is used. + chan.c:735,742 + Aaccess means that the file is checked (for existence, + attributes, etc.) The author walks to the final component. For + the ``.'' special case, no walk is done, since the whole path + was already traversed (ignore domount). For the ``/'' special + case, isdot is not set and walk is called; however, elem is the + empty string and walk would notice and return without doing + anything. + chan.c:744,753 + The name refers to a directory the user is trying to get into. + The author walks to it, and checks that it is actually a + directory. For the special case, nothing is done but to check + the directory flag. + chan.c:755,761 + The file is being opened. Directories can be opened too. + Forgetting about domount, in the normal case, just walk to the + file being opened; in the special case, no walk is really done + (not called, or it does nothing). + The author used an else instead of the break at line :738 + because more things have to be done by continuing after the + Open label. + chan.c:762,778 + If you remember sysopen, a channel was obtained for the given + path, but where was the file opened? Here is where the file is + opened. c points to the file to be opened. So, c->type is used + to obtain from devtab a pointer to the open routine--how to + prepare a file for I/O depends on who is implementing the file. + The ``close on exec'' bit is removed from the open mode + supplied to namec; the file server does not care about it. open + may return a different channel than the one for the file being + opened. That is useful, and allows the driver to ``generate + files'' when other files are opened, like when you open a clone + file. In that case, c already contains its own Cname and the + cname created before is unnecessary; the author sets newname to + reflect that. + Bits to flag the channel as close on exec, and remove on close, + are kept in the channel flags (remember that channels with + CCEXEC are closed on exec?). + Guess what is saveregisters doing? Hints: the compiler saves + registers when doing a procedure call (so that the called + procedure could use registers at will); if an error is raised + and you get back to line :714, which c are you closing? + chan.c:780,788 + Mount is not discussed yet, but note how in the special case + nothing is done and, in any case, c would be pointing to the + file where the Amount is to be performed. + chan.c:790,792 + The file is being created; remember that in the normal case,c + points to the directory where the file is being created at. If + the file name was ``.'', forbid creation. (See below for the + ``/'' special case). + chan.c:794,800 + Get a clone for c; read the comment. Clwalk does both a clone + and a walk for the channel; it is not used from the kernel (see + clwalk(5)). By getting a clone before walking, there are no + race conditions regarding clwalk--otherwise one of the + walk/clwalk could fail because both of them arrived to the file + server. + nameok()Name contains valid characters. + chan.c:805 + nameok checks that only valid characters are in the file name + (using the isfrog array). The 0 means that ``/'' is not ok. + nameok is also used to verify that a whole path is valid, in + which case ``/'' would be considered to be a valid character. + chan.c:806,812 + If the walk succeeds, the (cloned) channel points to the file + to be created; and the file already exists! c points to the + directory containing the file and is no longer needed. By + setting OTRUNC and going to Open, the file is opened with + truncation to zero bytes--achieving the same effect of create. + For the ``/'' path, walk would succeed and ``/'' would be + opened with truncation, which would typically lead to an + (Eperm) error. + chan.c:813,814 + The walk failed (did not raise an error, but failed because of + its return code). That means that the file does not exist. The + cloned channel is closed, and c will be used to create the + file. + chan.c:819,820 + Forget this by now. It is just ensuring c is the appropriate + directory for creating a file; assume it is and createdir is + not executed. + chan.c:822,832 + When syscreate is called, the caller expects that the file + would be opened and empty after syscreate returns. The + algorithm would be simply ``if the file does not exist, create + it; else truncate it''. However, things can change during the + algorithm. Just in case file creation fails, assume that it + could be because another process created the file (after the + failure of the previous walk and before the create operation + was executed). That can happen more easily here than on a + centralized system because the latency of file system + operations while going through the network is not to be + underestimated--see figure [227]5.2. + + CAPTION: Figure 5.2: Open/Create races. Not so probable... + + Should the create fail, try once more to walk to the file. If + the file was indeed created, the walk in the error handling + code will succeed and namec behaves as if the previous walk + succeeded. If this second walk fails, it makes no sense to try + over and over to ``create it if walk fails'' and ``walk to it + if create fails''. A real fix could be done by folding the open + and create operations into a single one, so that the file + server could hold a lock for the file while deciding whether to + create the file or truncate it. + chan.c:833 + Here is where the actual create is done. c is the directory + where the file is being created and elem holds the file + name--special cases were dealt with before. The final argument + perm is used now to establish initial permissions for the file. + chan.c:834,839 + Close on exec and remove on close noted in the channel. + chan.c:847,852 + newname was set to true before starting to resolve the path. It + is only set to false after Open, when the channel returned by + open was not the one supplied. Only when open returns an + already constructed channel, the name in the channel is + ``old''. Otherwise, the name for the channel has been built + from the user supplied path, and perhaps from the current + directory name. Thus, most of the times, the channel name is a + new one built by namec. Should the channel name be new, + cleancname does some cleanup on it, and it is set as the new + name for the channel--after releasing the previous name in the + channel, if any. Should the channel name be an ``old'' one, the + new cname just built is not used and has to be released. + By the way, how does cleancname work? + cleancname()Cleans a channel name. + chan.c:604,623 + cleancname calls cleanname for both device paths and other + paths. However, for kernel device paths, only the portion of + the part after the slash (e.g. ``/a/b'' in ``#S/a/b'') is + handed over to cleanname. As cleanname may leave a final slash + for directories, it has to be removed (:619) for all kernel + device names but for the root driver, whose name is #/. + cleanname()Cleans a file name. + /sys/src/libc/port/cleanname.c:9,52 + The code looks more complex than it is. Although you should try + to implement the algorithm yourself if you think the code could + be easily written in a more compact way. It does several + things: removes duplicated slashes, removes any ``.'' (but for + the case when the path is just ``.''), and simplifies ``b/..'' + by removing both. The ``..'' in ``/..'' is removed because the + parent of the root directory is the root directory by + convention. The path may contain ``..'' when no simplification + can be done (as in ``../x''). + Try to understand the code yourself after reading carefully the + comment. If you get lost, exercise the algorithm with several + paths. + By the way, the author put much effort into name cleanup at + several places, as you saw. Although that can be worth just to + keep cleaner names, there are good reasons for this effort, as + you will see later. + +Adjusting the name space + + Name spaces are adjusted (on a per-process basis) by using bind(2) and + mount(2) system calls. Read their manual pages now. + + Both system calls are essentially the same thing: They modify the name + space so that a path will lead to a different file tree. The + difference between them come from where is the ``different tree'' + located. For bind, it is a portion of the file tree the process sees, + whereas for mount it is a file tree serviced by a different process. + In what follows, unless I explicitly tell otherwise, I use the term + ``mount'' to refer both to ``mount'' and to ``bind''. Besides, I use + the term ``mounted file'' to refer to either a file or a directory + which is either bound or mounted; I use the term ``mount point'' to + refer to either a file or a directory where either a file or a + directory has been bound or mounted. Got confused? read bind(2) and + reread this paragraph. + + The name space structure is mostly kept under the Pgrp structure for + the process. + + When a directory is being mounted (or bound) onto an existing + directory, it is feasible to keep both the previous and new contents + in place. That is, by mounting a new directory onto an existing one, + you can ``add'' the contents of the new one to the existing one. That + is done often with /bin, where new ``binaries'' are added by mounting + other directories like /386/bin, and /usr/$user/bin onto /bin. When a + file is looked up later in /bin, it can be found at any of the mounted + directories. A directory where several other directories are mounted + is called a union in Plan 9. + + When a new directory is mounted onto a union, the user requesting the + operation can specify where to place the new directory within the + union. That is important because to lookup a file on a union, each + directory mounted in the union is searched in order until the file is + found. Flags like MAFTER/MBEFORE request that the new directory be + added after/before the previous ones in the union. For example, + depending on the flag, /bin/cat may be either /386/bin/cat or + /usr/$user/bin/cat. Another useful flag is MREPL, which dictates that + the previous directories be omitted from the union so that the new one + replaces previous contents. + + Now, consider a file being created on an union. On which one of the + mounted directories is the file created? In the example, is it created + in /bin, in /386/bin, or in /usr/$user/bin? The author added an + MCREATE flag that can be given to any mounted directory. Any new file + is created in the first directory mounted at the union that has the + MCREATE flag set. + + You now have an overall picture of how mounts work. But before reading + how mount and bind work, it is better to see what is the final effect + of a mount/bind. To do so, let's look at what does namec to resolve a + path taking into account mount points. + + Walking mount points + + namec() Get the channel for a given file name. + + chan.c:630 + namec resolved a name into a channel by walking a file + hierarchy. Now you know that, at some point, a new file tree + may be bound to the file tree, and namec should walk through + the mounted tree. + chan.c:725,726 + Before this point, the initial channel for the iteration has + been set to be c and elem contains the name for the first + component to resolve. Now, unless the path is for a kernel + device (!mntok), the path corresponds to the current directory, + or the path is not being resolved to mount the root directory + (elem is empty), domount is called. The channel to start the + iteration is the one returned by domount, which may be c or may + be not. + + namec + domount() Process mount points for a channel. + + chan.c:392 + domount is just ``doing'' the effect of a mount on a file. It + receives a channel for a file, c, and takes care of what + channel should be used instead when something has been mounted + on c. The processing for a mount point is done at a channel, + and not at a file. That is reasonable if you think that mount + is a client operation, and not a file server operation. The + client kernel sees the files through channels, therefore the + processing to honor a mount point can be done by looking into + the channel of interest. + chan.c:398,399 + First the name space (the process group Pgrp) for the current + process is locked for read. This is important since domount is + called often for dealing with possible mounts at a channel. + Since processes walking through the file hierarchy are not + modifying it, they can ``read'' the information for the + channels traversed at the same time; a read lock prevents any + change while there are readers, but allows multiple readers at + the same time. + chan.c:400,403 + A channel has an mh field, that points to a ``mount head'' or + Mhead. An Mhead (portdat.h:232,239) contains information about + what is mounted upon the channel: from is a reference to the + channel used as a mount point, mount is a reference to whatever + is mounted there. The information about what is mounted in the + channel is actually found in the list starting at mount; from + is used just to recover the mount point given the Mhead. + At these lines (:400,403), any previous reference to an Mhead + for the channel is released (putmhead only drops the reference + to the Mhead). More later. + chan.c:405 + domount iterates over a set of MHeads. + portdat.h:394,405 + Apart from the noattach flag, and a read/write lock, you see an + array of MNTHASH Mhead hash entries. This is the real mount + table; see figure [228]5.3. Each ``process group'' has a + namespace with mount entries dictating how is the namespace + modified for the Pgrp. The MOUNTH macro applies a simple hash + function to a channel and returns the hash bucket for it on the + mount hash table. The hash function uses the qid.path to hash + the channel. + + CAPTION: Figure 5.3: Mount structures. Here you can see how two + directories have been mounted over /bin, with the MBEFORE flag. + + The loop iterates on the hash slot for the channel, which has a + list of Mheads for channels with the same hash value. The list + is built using the hash field of Mhead. + The mount information is kept at Pgrp, in the hash table, and + not at the mh field of Chan; mh is just a ``cache'' for the + mount information--so that the table does not need to be + scanned all the times. + chan.c:406,407 + Different channels may have Mheads (because they were used as + mount points), and different channels may have the same + mount-hash (MOUNTH) value. Therefore, not all channels in the + hash list point to c's mount point--if any. After acquiring a + read lock on the Mhead, c is compared with the from field of + the Mhead. Now, the check is done using eqchan, and not ==. + Why? + eqchan()Are both channels referring to the same file? + chan.c:212,223 + eqchan is needed because two different Chans can refer to the + same file. Regarding the kernel, if two channels point to the + same file, they can be considered to be the same--for mount + purposes and other things. + Remember that two channels are a reference to the same file if + their Qids, device type, and device number are the same. In our + case, pathonly is true, which means that vers in the Qid is + ignored. Remember, the author is locating Mheads for the c + channel, he doesn't care if the mount point is modified or not + since the time when m->from was set as a mount point (Mhead) in + the mount table. No matter if c is physically the same channel + kept in the table, if its file is used as a mount point, it is + recognized in the table. + chan.c:407 + If the channel in the Mhead does not point to the file c points + to, it is a different mount point; ignore it. If the channel + does not correspond to a mount point, it will not be in the + hash list, and the routine returns the original c channel. In + this case, namec would continue using the initial c channel. + chan.c:408,413 + The channel is the same, so c is a mount point. cclone gets a + clone of m->mount->to, where m was the Mhead for c. Let's see + what this means. + portdat.h:220,230 + Mheads have a mount field pointing to Mount structures. The + Mount (list) represents file(s) mounted at the channel whose + Mhead has the Mount linked at. Several fields are + self-describing: next points to following Mount'ed trees at the + same mount mount; head points to the Mhead, so that both the + mount point (head->from) and the list of mounted trees + (head->mount) are accessible; and to points to the channel for + the mounted tree. See figure [229]5.3 if you got confused. + So, if you mount /usr/nemo/bin onto /bin, there would be + channel for /bin, with an Mhead entry in your Pgrp. That Mhead + would have from pointing to the channel for /bin, and mount + pointing to a list of Mount structures. That list would have a + Mount structure with to being a channel to /usr/nemo/bin. + chan.c:413 + nc is now a clone of the channel for the file mounted at the + file pointed by c. It points to the same file to points to. A + clone channel is needed because the returned channel is going + to be walked upon return from domount; the author does not want + m->mount->to to walk, it should be kept pointing to the mounted + tree. If you read nc as ``new c'', it is clear what the code is + doing. + chan.c:414,415 + As it was done with c, if nc has an Mhead cached at mh, release + it. + chan.c:416,418 + So, what was mh in Chan? It is set to the mount header for a + channel that is used as a mounted file tree. The usual picture + is to get a channel c, then do a domount for it, and later use + its mh field to operate on the mounted tree. + It is important to see that since nc->mh points to the MHead in + the list, successive mounted files can be quickly found by + following next pointers in the Mount list. You should remember + that nc represents not just the first mounted file; it also + provides access to any other mounted file in the same mount + point (by means of mh). + The xmh field is set as mh when domount crosses a mount point, + therefore it is the ``last mount point crossed''; But it seems + to be unused. Either a previous version of the kernel used xmh, + or it is there for debugging purposes. The last line adds a + reference--because of mh. + chan.c:419,421 + Channels keep the file name used to create them, as you know. + The name for nc is not the name of the mounted tree, but the + name of the mount-point--which was the name given by the user + to namec. The Cname is now shared. + chan.c:422,426 + c is released, its name will stay because of the added + reference. From now on, the caller of domount should use the + channel to the mounted tree instead of the channel to the mount + point. + + namec + + chan.c:725,732 + Back to namec, c is now the channel to the mounted file--or the + original channel if nothing was mounted on its name. At lines + :728,732, walk would call domount for every path component + resolved if mntok is set to true. That means that during path + traversal, what you read about doing a domount for the initial + path component, is also done for each remaining path components + (because each one could also be a mount point). + In the first two lines, if the path is ``.'' , isdot is set and + domount does not execute. That means that for the current + directory, c is the original channel and not the one for any + file mounted on it. Besides, if the path is ``/'' (elem is + empty) and it is being accessed for mounting, domount does not + execute either and c is also the original channel. Why? keep on + reading... + chan.c:736,739, :756,757 + The domount for ``.'' is done if the access is for Aopen or for + Aaccess (e.g., if you open ``.'', you would be opening the + mounted file, in case there is one) However, should the access + be for Atodir or Amount, the original channel is used (i.e. the + mount point is not traversed). By default, the author does not + execute domount at line :726 and then executes it later for the + two cases where it should be done. Why shouldn't it be done for + Atodir and Amount? + chan.c:745,753 + All Atodir (cd) accesses got domount executed at line + :726, but for an Atodir into ``.''. Thus, for Atodir + accesses, ``.'' resolves always to the mount point for + ``.'', and not to the mounted file--if any. + Suppose you ``cd'' into a directory. ``.'' is resolved and + up->dot is set to the mount point for that directory. + Suppose you later use (not for ``cd'') a relative path, + either ``./something'' or ``.'', domount will be called + (for a clone of up->dot) to resolve ``.''--it is called + either by walk or by explicit calls at lines :736,739 and + :756,757. This means that if you mount something at ``.'', + any future relative path will traverse the mount entry + just added for ``.'', even though up->dot was set + (resolved) before the mount was done. That is the meaning + of the comment at lines :745,748; if there were a domount + here for isdot, you would resolve the mount when cd'ing + into ``.'', any ulterior mount would not be processed by + your relative path resolution, because up->dot already + crossed the mount point. + chan.c:780,788 + Regarding the other case when domount is not called for + ``.'', it also affects ``/'' paths. When namec resolves + ``/'' or ``.'' to mount something on it, domount is not + called. When the path has more elements, domount is not + called for the final path element (walk called domount for + all but for the last element). So, in few words, domount + is never called for the last path element when it is being + resolved to mount something on it. Why? + That is because the new Mount is going to be added to an + Mhead for the original channel. When you resolve a path to + mount something on it, the channel from namec is the + original channel for the path, and not the channel for + anything previously mounted on it. For example, if you do + three mounts on /bin, the three Mounts would be linked at + an Mhead setup for the first mount. That Mhead would be + the header of a list of three Mount entries. To say it + other way, you mount to the mount point, not to something + mounted on it. + + What remains to learn how are mount points traversed is to see what + does ``walk'' when walking through a mount point. Of course you + already know how domount works, but that is only part of the story + (given a file, go to the thing mounted on it); the other part of the + story is what to do when you have a directory that is a mount point, + and you have to lookup names on it, or to create names on it. + + Directory walking + + walk() Walks to a name on a channel. + + chan.c:493 + walk is called to resolve a file name (no paths!) on a channel. + The channel points to a directory (mounted or not). After walk, + the channel points to the file named name within the directory + pointed to by the channel given to walk. When the directory is + mounted, there many be more than one directory mounted. domnt + tells walk whether the given directory is considered to be + valid as a mount point; if it is not, no mount related job has + to be done. + chan.c:499 + ac is the ancestor channel (the parent you are walking + through). cp is a pointer to a Chan pointer; that is to update + the passed Chan. After a walk, the caller might be using a + different channel than the one given to walk. + chan.c:501,502 + I told you. + chan.c:504,508 + redundant ``..'' names were removed, but what about the ``..'' + path? In this case, undomount returns the channel for the + ``..'' file; more later. + chan.c:510 + Walk is going to move the channel to a subdirectory or to a + file contained in the directory represented by the channel. If + the passed channel had a CCREATE flag stating that it was + mounted allowing file creation, clean it up so it does not + pollute the inner file. + chan.c:511,517 + First, the device specific walk routine is called. That is to + tell the file server that the file being used by this client + (the kernel), and identified by the channel, should now point + to name instead. If the device walk succeeds, the ancestor file + contained a component named name; + Domount is called on the channel after the walk. The channel + points to the file named name, but if something was mounted on + that file, domount will find a mount hash entry for the channel + Qid, and traverse it. Next time walk be called on the channel + it will walk within the mounted tree, not within the mount + point. + An interesting implication of calling the device walk before + looking at mount points, is that to use bind on a file, the + file must exist, not just its name. However, that is reasonable + given that all you have to bind something on a file, is the + channel to the file. The ancestor of the file has nothing to do + with it. What I mean, is that bind is not like link on UNIX. + updatecname()Updates the name of a channel after a walk. + chan.c:477,490 + updatecname adds name to the cname in the channel, so that + cname still corresponds to the name of the channel file. Now ac + is a channel for the file named name. For ``..'', updatecname + uses undomount as walk did before; more about that later. + chan.c:519,520 + The device walk failed; i.e. there was no such file below the + file pointed to by ac. Now what? + The device walk just tried the name in the served file tree; + But it could be that the ancestor channel is a directory with + other directories mounted on it (i.e. you are walking through a + union). In this case, the channel has a non-nil mh pointing to + the Mhead for the mount point. Besides, it is clear that in + this case the walk could fail yet the file may be there because + of a mount. + Remember that the channel mh was set by domount, in case the + channel had something mounted on it. Well, not exactly, domount + received a channel with something mounted on its file name, and + domount returned a substitute channel for the mounted file, + with mh set; but you get the picture. What follows is done only + for channels that correspond to mount points. + chan.c:522,530 + Going to exercise mounted files in turn. Hold a read lock on + the Mhead. + chan.c:531 + Remember, mh->mount is the first Mount entry for the channel, + and they are linked through next. The author is iterating over + the mounted files. + chan.c:532,537 + After getting a clone for the channel pointing to the mounted + tree, try the walk on it. Should it work, we are done: got the + file!. Otherwise, try with the next mounted thing. Why is a + clone needed? Hint: consider what would happen to the mount + entry if its to channel was used for the walk. + chan.c:542,543 + No luck, no such file at any unioned directory. + chan.c:545,548 + Because c is already resolved, drop its mh reference, if any. + cclone asked the device for a clone channel, it may come with + an mh reference, but it should have none; because it is already + resolved and it does not represent the mount point--it + represents just the file mounted on it. Should mh remain set, + further calls to walk could try to iterate over the mount + entries found through it. + chan.c:551,556 + The name for the channel updated. The name coming out of the + mounted tree is mostly ignored, and the channel name is updated + to contain the name for the channel given to walk plus the + element name: the channel name is the name used by the user to + walk from the root to the channel. Two channels may point to + the same file, yet have different names because of bind. Start + to understand why channels have cnames? + chan.c:557,561 + The channel given is updated with the new channel, and it is + checked as a possible mount point by domount. Although the + channel points to a file in a mounted file tree, its name can + be a mount point too. domount would replace the channel with + that of the mounted file, if any. + + To completely understand walk, you still must read how undomount + works. Undomount is the one who understands the meaning of ``..'' when + it must cross a mount point (hence its name). + + Consider the case when /usr/nemo/bin/rc is bound to /bin/rc. Now, + imagine there is a directory /usr/nemo/bin/386. If you walk to /bin/rc + you end up in the same directory as if you walk to /usr/nemo/bin/rc. + Consider the case when you do the last walk. Your file is + /usr/nemo/bin/rc. Imagine that you walk to ../386, your file is + /usr/nemo/bin/386. Now consider that you walk to /bin/rc, if you later + walk to ../386, you should end up in /bin/386, not in + /usr/nemo/bin/386; even tough ``../386'' was applied to a channel + really at /usr/nemo/bin/rc! + + When doing a ``walk("..")'', the new file should be the parent of the + current file, but the parent regarding the path used to get to the + file. To pick up yet another example, if you use the path /bin/rc, you + do not care that it was really /usr/nemo/bin/rc, for you, ``..'' means + /bin, not /usr/nemo/bin/rc. + + By recording in channels the name used to create the channel, ``..'' + can be implemented that way. Both walk and updatecname call undomount. + + To make it more clear, consider in our example a walk to ``..'' on a + channel pointing to the file /usr/nemo/bin/rc whose cname is + ``/bin/rc'': + 1. + walk calls undomount (chan.c:506), which returns a channel + pointing to /bin/rc, given the channel pointing to + /usr/nemo/bin/rc. The channel name is still /bin/rc, and the + channel still points to ``rc''; but now you are at the /bin/rc + tree, not any more in the /usr/nemo/bin/rc file tree. + 2. + Later (chan.c:511), walk calls the device specific walk + routine, which would do a walk("..") in the channel for + /bin/rc, making the channel point to the file /bin. You are + mostly done, but for the channel name, which is still /bin/rc. + 3. + At line chan.c:513, updatecname would build a name /bin/rc/.. + and simplify it, leading to /bin. You are done! + updatecname calls undomount too. When /bin is also a union, + updatecname would return the mount point for the union, and + later chan.c:515, domount would return the channel for the + first mounted directory at that mount point. That channel has + the mh field set so that lookups in unions could work for it + too. + If walk fails when calling the device specific walk for ``..'', + it would continue below line :517; if the channel is a union, + the same device_walk+updatecname+domount sequence is played at + each unioned directory. + + ... + undomount() Goes from the mounted file to the mount point. + + chan.c:436 + Back to undomount, it does part of the ``walk'' for ``..'' on c + . In our example, the channel for /bin/rc after the bind of + /usr/nemo/bin/rc, was really a channel to /usr/nemo/bin/rc; + only that its Cname was /bin/rc. Undomount steps back from the + mounted file, to the mount point. + chan.c:443,448 + The meaning of ``..'' depends on the mount table. + chan.c:450,453 + he is the end of the mount table. The loops are iterating over + the entire mount table: all hash buckets, all mount points, all + mounted files. A very expensive operation! (hence the effort to + remove unnecessary ``..'' elements in path names). Hopefully, + there will not be so many mount entries and this would not have + a noticeable impact on system performance. + chan.c:454 + The channel c corresponds to a mounted file (it would be an + entry for /usr/nemo/bin/rc mounted somewhere). + chan.c:455,462 + But, in our example, you don't know whether it is the entry for + the mount at /bin/rc, or it is an entry for a mount at a + different mount point. t->head is the Mhead for the mount + entry, t->head->from is the channel for the mount point; its + name->s is the C string for the mount point channel name. + Should the string be the same that the one in c's Cname, the + mount point is the one we are looking for (e.g. it would be + /bin/rc). Otherwise the loop continues searching. + chan.c:463,467 + Strings did match, so to step back the union, get a clone of + the mount point and stop the search. + One final note about this. The author breaks just the inner + loop and I don't see the point on searching remaining mount + points once one has been found--I mean that the two outer loops + would continue. I think this is a bug which affects just + efficiency, although the author may have a good reason for + doing so. + + Creating files on mounted places + + You may remember that + + namec + + chan.c:819,820 + while resolving a name for creation, namec tries a walk to the + file, and reaches these lines if the walk failed. The file + named elem is going to be created under the file pointed to by + c. However, if mh is not nil in c, it is a mounted file. + Besides, it is one of (maybe) many files mounted at the + directory where the elem file has to be created. On which one + of these mounted directories must the file be created: on the + first in the union that has the MCREATE bit set. Channels to + mounted files have the CCREATE bit set if their mount had the + MCREATE flag. So, if this channel (the first in the union) has + the CCREATE flag, it is the channel to the directory where the + file should be created. + + namec + createdir() Chooses where to create a file in a (union) directory. + + chan.c:567,593 + Otherwise, createdir locks the Mhead and iterates over the set + of mount entries. The first one with the CCREATE bit set is + cloned, and the clone returned. namec would then use the + channel for the first directory mounted with MCREATE to create + the file on it. + The mh field of the cloned channel is cleaned up, and reset to + be the mh for the channel c (i.e. for the first mount entry). + If the creation fails and another walk is tried once more, the + walk would use the mh field to lookup names in the union. + When no mount entry has the create bit set, an error is raised + and file creation is aborted. + + Mounting and binding + + sysbind() Entry point for the bind system call. Binds a name to + another name. + + sysmount() Entry point for the mount system call. Mounts a file tree. + + sysfile.c:687,697 + Both bind and mount are implemented by calling bindmount. The + last parameter is an indication that a mount is being done. + + sysmount + bindmount() Mounts or binds a file to another. + + sysfile.c:624,629 + The third parameter flag controls how the operation behaves. It + is a bitmap of bits defined in lib.h:85,91. The two low bits + are used to specify the order for the new directory. The user + cannot request both that the directory be mounted before and + after the previous ones. Besides, only bits in MMASK are valid + flags. MCACHE requests that file data should be cached, and is + noted in bogus. Bogus is being initialized to contain the + information about the mount. + sysfile.c:631,662 + For mount, a file descriptor is supplied as a first argument to + bindmount. Must convert it into a channel. For bind, it is a + path, which must be converted to a channel too. + sysfile.c:632,633 + mounts are forbidden if the noattach bit is set. It is okay to + bind because no new files are brought into the name space, but + no new file trees can be attached. + sysfile.c:635,640 + fdtochan takes a file descriptor and returns a channel for it. + The last parameter specifies to add a new reference to the + channel. Should an error occur, cclose would drop the + reference. The channel corresponds to the file descriptor being + mounted, and is noted in bogus. On the other end of the + channel, there should be someone speaking 9P, to service file + requests. + sysfile.c:642,650 + For mount, a request is going to be issued to the file server + to attach its file tree to our name space. As a server can + service several trees, the fourth argument of mount specifies + (as a string) which file tree to mount. The author is ensuring + that the string is in valid virtual memory, and noting the + string into bogus.spec. nameok is used to check that the spec + has a valid path (i.e. valid characters); it is okay if spec + contains slashes, hence the 1. + sysfile.c:652,656 + The file tree being mounted is serviced by a remote process + which speaks 9P. The client is going to be the kernel mount + driver, which translates procedure calls into 9P RPCs as the + mounted tree is used. The attach procedure of the mnt driver is + used to get a channel to the remote process: First, knowing + that the name for mnt is #M, devtab is searched by devno. devno + returns a valid channel type (an index into devtab) for the + mount driver; Second, the attach procedure for the driver is + called supplying the bogus structure just filled up. If you + look at it, bogus contains a channel to the server, the spec + for the file tree requested, and an indication of whether files + are being cached or not; everything attach needs to get in + touch with the file server and attach to it. This is discussed + later. + If attach completes without error, c0 is a channel to the (root + of the) file tree in the server, which (after completion of + attach) recognizes us as a valid client and is willing to talk + 9P with us. + sysfile.c:658,662 + The first argument for bindmount was the path given to bind; + therefore, to obtain a channel it suffices to use namec to + resolve the path into a channel. c0 is now a channel to the + file tree being mounted. + sysfile.c:669,674 + The second argument was the path for the directory where the + file tree is being mounted at--or for the file where the new + file is being bound at. namec is used to get a channel c1 for + the mount (or bind) point. Note how Amount access mode is used + in namec; c1 would be the very first mount point for arg[1]. + sysfile.c:676,685 + The first line is where the mount is being done; what remains + is to close both channels (mount point/mounted file) because + the mount table already holds what it needs, and to close the + descriptor supplied to mount in case it was a sysmount. The + descriptor is closed because the kernel is going to exchange 9P + messages on it with the file server; the user would only + interfere and cause problems. But how does cmount work? + + sysmount + bindmount + cmount() Adds a mount entry. + + chan.c:226 + cmount is called with channels for the mount point (old) and + the mounted file (new), the flags and any spec are passed too. + chan.c:233,234 + It is okay to bind a file to a file, and a directory to a + directory; but not for any other case. Don't trust users! + chan.c:236,239 + If mounting with MBEFORE or MAFTER, ensure channels are for + directories; otherwise, it has no sense--for files, you only + can replace entire file contents. + chan.c:241,242 + Going to write the Pgrp, stop any further lookup/change to the + name space. + chan.c:244,249 + Search the name space for any Mhead for this mount point (note + eqchan again!). If an Mhead is found, m points to it; + otherwise, m would be nil. + chan.c:251,269 + The comment says it all. The from field of the Mhead is set to + the mount point--and the reference noted by incref. As you now + know, the point is not that this particular channel is set in + the from; the point is that a channel with its cname, its type, + its dev, and its qid is sitting at the from. + Lines :267,268 may add a mount entry for the mount point itself + to the Mhead. Guess why? + Exactly, if the mount is not an MREPL, previous contents at the + mount point are still visible; therefore, the channel to the + mount point is added as if it was one of the directories + mounted on it. When later the mount entry list be searched, + names originally at the mount point will be searched too. So, + the Mhead has now either the original mount point channel, or + it is empty. + newmount()Adds a new mount entry. + pgrp.c:231,245 + newmount simply allocates a Mount entry, and initializes it. + The author sets to i to the channel for the mounted file; and + sets the pointer to its Mhead. + mountfree()Releases mount entries. + pgrp.c:247,259 + The counterpart of newmount is mountfree, which releases + references to the channels for the mounted files as well as the + mount entries. + chan.c:270,275 + After the mount entry is locked, there is no need to keep + locked the whole name space. + chan.c:277 + An entry for the new mounted file is created. + chan.c:278,292 + As the mounted file could itself be a union, any mount entry + for the mounted file must be copied to the list of entries for + the mount point. The author links a copy of each such entry + starting at the next pointer for the new mount point being set + (nm). + If the mounted file is to replace the mount point, its mount + entries are set with the MAFTER flag. I don't think this flag + is used for anything. The point is that the Mhead for the mount + point has either its previous mount entries, or an entry for + the old contents if appropriate; besides, the new Mount has all + entries for the mounted file linked on it through the next + pointers. + chan.c:294,297 + If this mount was an MREPL, cleanup all previous mount entries + for the mount point. mountfree releases all the mount entries. + chan.c:299,300 + Cache the MCREATE flag on the channel, so createdir only needs + to look at the channel. + chan.c:302,306 + If mounting after, skip any previous mount entry at the Mhead, + and link the new mount point (and all trailing mount entries + for directories mounted at the mounted file!) at the end. + chan.c:307,312 + Link the list of new entries before the previous ones. If mount + was MREPL and not MBEFORE, the list was already cleaned up, so + a ``link before'' works too. In the case of MREPL it could be + more efficient not to iterate the list being added to the Mhead + (because that is just to set the last next pointer to nil), but + nobody cared to optimize that. Would the user notice the + optimization? + + Mounted files can be unmounted by calling unmount. + + sysunmount() Removes a mount entry. + + sysfile.c:700 + This is the entry point for unmount + sysfile.c:706,707 + The name for the mount point is resolved (note the Amount + access) and cmount is now a channel to it. + sysfile.c:709,717 + If the first argument is not nil, it specifies the mounted + file--in this case the user wants to unmount that specific + mounted file, and not any other one. The address is checked and + namec used to get a channel for the mounted file (note the + Aopen access mode). Should the first argument be nil, cmounted + remains set to nil. + sysfile.c:726 + cunmount undoes the mount. Note, not undomount! + + sysunmount + cunmount() Undoes a mount. + + chan.c:329,334 + The Mhead is located for the mount point--yes, perhaps a + getmount routine could be created to do the lookup and share + these lines among routines looking up mount entries. + chan.c:336,339 + The user could call unmount on a file with nothing mounted on + it. + chan.c:341,352 + If shouldn't care about unmounting a particular mounted file, + mountfree is called on the whole list of Mount entries. All + entries are released and the head released too. All mounts are + undone. The unlock is done in any case after locking the + particular MHead of interest. + chan.c:354,376 + The user cares of unmounting a particular mounted file. So, + iterate the set of mount entries for the mount point. Iteration + stops when an entry is found such that its to channel is eqchan + to mounted. (Line :358 checks if the channel used to talk 9P to + the server of the mounted directory is eqchan with the mounted + directory; this can happen with exportfs, as you will see later + when you read about the mount driver). If the entry is found, + it is removed from the list and released. If the list gets + empty, the Mhead is released too. If no entry is found, an + error is raised--that ``mounted file'' was not mounted at the + union. + + Creating and destroying name spaces + + Other routines that operate on name spaces are the ones creating an + empty name space, copying an existing name space and deleting a + namespace. That happens as a consequence of rfork and process death. + + sysrfork + newpgrp() Creates a new name space. + + pgrp.c:42,51 + An empty Pgrp is created with everything set to nil. As a + result, the mount table hash is empty and noattach cleared. You + saw in a previous chapter how pgrpid was assigned later. + + sysrfork + pgrpcpy() Copies a name space. + + pgrp.c:124,130 + pgrpcpy is used to copy a name space into another. Only the + source is locked because the target is still being built. + pgrp.c:132,159 + Hash entries are replicated so that to holds a copy of the + mount entries in from. Note the increfs when structures are + shared (Channels are!, because the namespace is copied, but + channels to mounted file systems and mount points are not!). + The loop is simple to understand if you notice that for each + pass (:135) an Mhead f is being copied into a new one, mh, (l + is used to build the list); and at each inner pass (:144), + Mount m is being copied into a new one, n. + The field copy of m is set to n (the place it is being copied + to). pgrpcpy relies on pgrpinsert to link mount entries being + added through the Mount.order field. Both copy and order seem + to be in Mount just for this occasion--to save the author the + burden of allocating a whole bunch of data structures during a + brief amount of time just to copy the set of mount entries. + pgrpinsert()Inserts a mount into a list ordered by mountids. + pgrp.c:100,118 + What does pgrpinsert do? It receives the pointer to the Mount + being copied and a pointer for the start of the ``order'' list. + If the list is empty, it is set to the node just copied. If the + list is not empty, f advances until its mountid is bigger than + the one for the node copied. So, pgrpinsert is building a + sorted list of Mount entries. The list is sorted in ascending + order of mountids. + pgrp.c:163,167 + That was the list for, mountids for the copied entries are + assigned in the same order they were assigned for the original + Pgrp. Why? + The mountids can tell the order in which the user issued mount + requests that resulted in the set of Mount entries. That order + does not correspond to the order of entries in the Mhead, + because of the MBEFORE/MAFTER flags. The proc driver services + an ns file that returns (when read) commands to replicate the + namespace. It relies on the order of mountids to reproduce the + commands in the appropriate order. + Execute in your Plan 9 box a couple of mounts and then execute + cat /proc/$pid/ns. More clear now? + + closepgrp() Releases a name space. + + pgrp.c:71,97 + closepgrp is called to release a reference to the pgrp. When it + comes down to zero, all entries are released. Two locks are + needed: devproc uses the debug lock, although routines using + the namespace use the ns lock. + + File I/O + + Once a file descriptor is open, the user can use read(2) and write(2) + on it. Although the actual implementation is done by the server + servicing the file, functionality such like the file offset is kept at + the client side and is provided by channels (You already know what a + file offset is, if you don't, read the ``File I/O'' section of + intro(2)). + + That is a fine way the author has to side-step the problem of sharing + file offsets on distributed file systems: by not doing it! Take this + as an example of the principle that, before adding a new feature to + your system (e.g. sharing file offsets among several nodes) you should + ask yourself what is the benefit, and what is the cost; then decide. + + The most useful feature of shared file offsets, i.e. allowing several + related processes to consume/produce the same file, is still here: + * Several processes (within the same node) can share a file + descriptor and that means they would share the file offset too. + * The ``append only'' bit of file permissions can be used to allow + several processes to produce contents for a file no matter the + node they are running at. This is in effect ``sharing'' the file + offset, which is always kept at the end of file for write + purposes. + +Read + + sysread() Entry point for the read system call. Reads from a file. + + sysfile.c:375 + sysread receives a descriptor and a buffer together with its + length. It is expected to fill up the buffer with bytes coming + from that descriptor. The bytes can come from an actual file, + or from a file synthesized by a file server, nobody knows. + sysfile.c:381,383 + Buffer addresses are verified and c is set to the channel for + the descriptor. The channel should have the OREAD bit set. + Remember that when you open a file, its mode is cached in the + channel. Although permissions are checked by the file server, + when the device specific open routine is called, once the file + server granted access, the mode is kept in the channel. Future + access checks can be done by the client without disturbing the + server (although the server is likely to check that the file id + has the OREAD bit set too). + The last 1 to fdtochan requests an incref for the channel. + Should the descriptor be closed by a different process, the + channel would stay alive because of the added reference. Forget + by now the 1 asking checkmnt to fdtochan. + sysfile.c:390,396 + If the channel Qid has the CHDIR bit (it is a directory), a + read should return a integral number of directory entries (See + the read(2) manual page). The buffer length (n) is adjusted to + be a multiple of the directory entry size DIRLEN. Should the + channel offset be not a multiple of DIRLEN (shouldn't happen) + or the buffer too small to keep even a single entry, Etoosmall + is raised. + sysfile.c:398,405 + If c is a union, read should get entries from all the mounted + directories. + It is easy to know if this is a union; remember that the + channel installed for the file descriptor was obtained with + namec and Aopen access mode. That means that any mount point + was traversed and mh initialized in the channel to point to the + Mhead. + Thus, if there is an mh in the channel, unionread reads entries + from each directory mounted. Otherwise, the device specific + read is called. The device should honor the convention that a + read from a directory should return an integral number of + directory entries. Should the device fail to honor that + convention, the channel offset would be set to a non-multiple + of DIRLEN at line :404, and the next read will fail. The offset + for the file is kept by the channel; you already knew this. For + directories, the file offset counts bytes, and not directory + entries! as it should be. + The channel is locked just while changing its offset. Apart + from that, it can be used safely without locking because it is + not going to be deleted, nor its device type is going to + change. The real read is done by the device, which could stand + miles away, and there is no guarantee that while this read is + in progress no other read could be made. Nevertheless, the + server is likely to serialize read/write requests for the file. + + sysread + unionread() Reads from a union. + + sysfile.c:280 + unionread does the work for reading the union while holding a + lock on it. + sysfile.c:291,292 + Where to start reading? If you read a union from the beginning + to the end, you should get all directory entries in all + directories mounted, as you find them in the list of Mounts. + The problem is that users tend to declare a buffer and read + repeatedly from a file; each read should start past the + previous read (remember offset, right?). + The author could use the channel offset and skip as many Mount + entries and directory entries as needed to fill up offset + bytes. However, that would be a waste because reading a union + would be O(n2) regarding the number of entries. You don't know + how many entries there are at each mount entry. Therefore, you + cannot compute how many entries to skip unless you read them. + Can you think of more alternatives besides re-reading them and + doing what is said in the next paragraph? What are the + benefits? What are the penalties? + Instead, an uri (union read index) field in the channel is used + to record how many mount entries were exhausted by previous + reads. That saves lots of reads that are likely to be serviced + from the network and not from a local cache. The loop at lines + :291,292 is skipping over already exhausted mount entries. + sysfile.c:294 + Keep on reading while there are mount entries to read from. + sysfile.c:299,300 + As far as I know, to is only released by mountfree, and that is + done with the lock on the Mhead held. Therefore I would say + that in no case to should be nil, but the check does not hurt + anyway. + + NOTE: Is this ok? + sysfile.c:301 + Going to read from to, so clone it. Otherwise, the channel + would be modified (e.g. its offset would change). Perhaps in + this case it would be more simple to save the previous offset, + explicitly set it up, use the channel and restore the offset. + But that would require that all channels for mounted + directories be kept open all the time; that would mean ``use + more resources'' for the file servers. Besides, it is a good + thing to keep channels for Mount entries untouched; the author + can rely on that to make the code more simple. + Don't you see any other problem here? You cannot walk on an + open file, so the clone is necessary anyway. + sysfile.c:305,308 + This is not the usual error handling block. Should an error + occur, the channel to the mounted directory is closed and the + routine continues at the next entry. That means that if a file + server goes down, only people really using it would be + affected. If a directory serviced by the crashed file server is + mounted, its entries will be ignored due to errors, but + remaining entries in the union would still work. This is the + kind of thing that makes a distributed system more reliable: be + prepared to tolerate remote failures bothering the user as few + as possible. + sysfile.c:310 + The device specific open for the mounted directory is called. + The clone channel is used. + sysfile.c:311,314 + The author is indeed adjusting offset by hand between + successive unioreads. The offset is saved in the channel for + the mounted file; But note how the offset is used only within + the same mounted directory. + sysfile.c:318,321 + If could read something, return that. If more entries remain to + be read, the user would call read(2) again. offset is adjusted + before returning so that next time the read would start where + it was left at. + sysfile.c:323,329 + If there are no more in the current mounted directory, nr would + be zero and this code execute. When an error happens, line :307 + would jump here too. Just increment uri to remember that the + current mount entry should be skipped next time. If there are + no more entries, break the loop and return 0 (eof). Otherwise, + reset the offset and iterate again, so that the next mounted + directory starts to be read at offset zero. + +Write + + syswrite() Entry point for the write system call. Writes in a file. + + sysfile.c:444 + syswrite has the same interface of sysread, but it writes + rather than reads. + sysfile.c:453,459 + Should an error happen, restore the offset in the channel. The + code following advances offset, yet it could fail. If an error + occurs, the write failed but the offset should be kept + untouched. Perhaps this would be more clear if the offset were + simply saved to a variable and restored from there, but the + author does not do so. Guess why? + sysfile.c:461,462 + The only way to write to a directory is by creating or deleting + files (also by changing file attributes). + sysfile.c:464,467 + Advance the offset by the number of bytes to be written. oo + keeps the old offset, and could perhaps be used to restore the + initial channel offset on errors, perhaps not. + sysfile.c:469 + Here is the actual write. The old offset is supplied and the + device specific write would write at that position. + sysfile.c:471,475 + The device could write less than n bytes. This is usually due + to an error (e.g. ``disk full''). If the device wrote m bytes, + the offset has to account for those m bytes. However, it was n + that was added to it, by subtracting n-m, it gets m units more + than it had before syswrite. Should the device write all n + bytes, offset is kept n bytes beyond its value before syswrite. + + Could you guess the reason for the dance around offset? sysread did it + in a more straightforward way, by simply adding n bytes to the offset + after the read was done. + + I think that the reason is that the author does not want the channel + to be locked during the whole syswrite. Suppose the channel offset is + o. For sysread, the worst thing that can happen if two different + processes are reading the same file (through the same channel) is as + follows: + * The first sysread calls read in the device and reads at offset o. + * The second sysread calls read, in the device, which also reads at + offset o! + * Both sysread increment the channel offset. + + Although this could be considered to be a bug (If I am not missing + anything here), the net effect is not harmful, as the file is kept in + a consistent state. Actually, I would say that the bug is at the + application, which didn't synchronize on its access to the file. + + Now consider syswrite. writes are different in that if they are mixed + the file could be left in an inconsistent state. Suppose again that + offset is o, and two syswrites are being done through the channel. If + syswrite worked like sysread (by adding n to offset after calling the + device write), the two writes could overwrite the same portion of the + file; e.g. the two calls to the device write are performed, then the + offset incremented twice (holding the lock for the offset). + + By incrementing the offset in the channel before calling write, any + following write through the same channel would ask the device to write + past the n bytes theoretically being written. Of course that means + that the offset must be restored (in case of errors) by doing + arithmetic and not by restoring the initial value. The reason is that + if the first syswrite fails, but in the mean time the second syswrite + could really write, offset should account for the written bytes by + both the first and the second syswrite. If you didn't understand, try + to exercise concurrent syswrites and see how are the file and the + channel left. I think that the approach used in syswrite should be + used in sysread too, but the author may disagree. + + Finally, note that when two different channels are used for the same + file (applications could run at different nodes), it is the + application responsibility to synchronize. The CHEXCL bit could help + here. As it is said in create(2), if a file is created with that + permission bit set, only one client may have the file open at a time. + That functionality is implemented by the file server, which serializes + file usage when notices the CHEXCL mode bit. + +Seeking + + The seek(2) system call can be used to move the offset in an open file + to a desired position. + + sysseek() Entry point for the seek system call. Moves the file offset. + + sysfile.c:535,541 + After checking the argument, sseek does the work. + + sysseek + sseek() Seeks on a channel. + + sysfile.c:495 + The first argument is the file descriptor to seek on. Get the + channel. But note the arg[1] (not arg[0]!) for the first + argument. + sysfile.c:500,501 + Should seek be allowed on directories, sysread could found + offsets not aligned to DIRLEN. So the author forbids that. + sysfile.c:503,504 + No seeks on pipes. Other file servers could perfectly ignore + seeks as well as they could ignore file offsets (i.e. they + could read always from the very first byte). But that's the + file server choice. + sysfile.c:506,509 + An vlong (second argument to seek) uses two longs. Now, the + arguments for system calls were assumed to be machine words + (longs). These lines use the u member of the o (offset) union + to fill up the two words of the vlong. Arguments 2 and 3 are + actually the second argument (two words) of seek. The first + argument was kept at arg[1] and not at arg[0]. That is because + arg[0] is kept unused to make the vlong stand aligned to an + vlong size boundary regarding the argument array. That is a + good thing if the code is pretended to be portable, as some + machines (not the PC) are very picky regarding alignment + issues. The user-level library stub to issue the system call + for seek must honor the same convention of wasting arg[0] and + pushing the vlong in the order in which it is being extracted + here. If the stub (machine dependent) honors this convention, + this code can be kept portable. Now you know also that arg[4] + is actually the third argument for seek, right? + By the way, look /sys/src/libc/9syscall/mkfile:50,61. + Understand the if now? + sysfile.c:509,528 + Depending on type, the n kept at o should be either used as the + new offset, added to the current offset, or used as the new + offset but counting backward from the end of the file. When + arithmetic is being done with the channel offset, a lock is + held. Does it makes sense to hold a lock just to assign the + offset? + If the offset can be written atomically, it doesn't matter; but + on Intels, in this case, two words are written as the new + channel offset. There is a very thin critical region here, and + the offset could be mangled in the very improbable case that a + sseek writes the offset, while another sseek does too. Just too + improbable, but perhaps that should be fixed. + Stat is used to get DIRLEN bytes with status information from + the file, and convM2D is used to convert that into a Dir + structure, from where recover the length of the file. stat is + discussed later, but convM2D is not. The DIRLEN bytes are in a + ``standard format'' and have to be converted to a native format + before used (byte ordering et al.). The reason for this all is + that Plan 9 is a distributed system. + sysfile.c:529,531 + The final offset value given to the user (line :506 is not + needed but it is good to keep it there for safety). uri is + reset, because unionread could use that to read entries? That + couldn't happen. If this is a directory, seek is forbidden. + However, it is a good practice to set uri to a reasonable + value, in case a bug (no check for directory?) is introduced in + the code by future changes. + sysfile.c:543,560 + You may have noticed that there is a sysoseek routine below + sysseek. If you look at system call numbers for seek and oseek + (/sys/src/libc/9syscall/sys.h), you would notice that seek is + placed the last one, and oseek is placed near read. That means + that the author had once just the seek system call, and it was + number 16 (OSEEK now). But seek was changed in a so + incompatible way, that the author preferred to keep both the + previous and the new version for seek in place. Old Plan 9 + binaries would have the library stub named seek that does a + system call with number 16, and that would call sysoseek. New + Plan 9 binaries would be built with the stub which calls seek + instead. This is a common technique to reduce the impact of + changes. What sysoseek does is to rearrange the argument array + so that a[0] contains the address of the vlong, and the vlong + is filled up with arg[1], which means that the change was + probably that seek received a long, and now it receives an + vlong. In other words, sysoseek is adapting the old interface + to the new interface, but the implementation of seek stands the + same. Try to learn from this all how to minimize the impact of + changes. + +Metadata I/O + + Files have attributes, and you already know some. They have + permissions, a name, owner, etc. The system calls reading/updating + attributes are stat(2), fstat(2), wstat(2), and fwstat(2). The former + two ones read attributes, and the later two ones update attribute + values. Services like chmod(2) are implemented by doing a wstat(2) on + the affected file. File attributes are read and written in a machine + independent format with DIRLEN bytes per file attribute set. Read + stat(5) if you are curious about file attributes. + + Let's see the system calls that read attributes before, and then the + ones that write them. + + sysfstat() Entry point for the fstat system call. Reads file + attributes (given a file descriptor). + + sysstat() Entry point for the stat system call. Reads file attributes + (given a file name). + + sysfile.c:563,578 + sysfstat takes an open file descriptor, and tries to read new + values for attributes. All the routine does is to get a channel + and call device specific stat to read the attributes. It is the + file server the one filling up the buffer with information + (probably) coming for Dir structures. + sysfile.c:581,597 + sysstat is the same, but takes a file name instead of a file + descriptor. namec does the job of getting a channel, and then + the device specific stat routine reads any attribute. Perhaps + both system calls could be folded into one, but it's not a big + deal. + + syswstat() Entry point for the wstat system call. Writes file + attributes + + sysfile.c:778,813 + The ``write attributes'' version of the routines simply call + the device wstat instead of the device stat. The only thing the + author verifies regarding the new attributes, is that the new + name for the file (first bytes in the buffer with attributes + supplied) looks fine and has valid characters. That is the only + attribute that would hurt 9P. Should the name be ok, the call + to wstat can be done, and remaining attributes should be + checked by the file server. + + This is another place where you can see how the design of Plan 9 works + well for a distributed system. File attributes are kept (together with + the file) within the file server providing the files. The system does + not impose any particular way of implementing file attributes. All + Plan 9 cares about is that the device should either be in-kernel, or + service 9P requests. Besides, by forwarding all calls related to file + metadata to the file server process, Plan 9 does not introduce new + problems related to metadata sharing over a distributed system. Yet + another point is that the file server is free to trust you and accept + wstat requests; it would do so if you authenticated the connection to + the file server. Saw how all pieces fit together? + + Other system calls + +Current directory + + The getwd(2) function is not a system call. It is a library function + that opens ``.'' and calls fd2path(2) on it. + + sysfd2path() Entry point for the fd2path system call. Returns the name + for a file descriptor. + + sysfile.c:120,135 + sysfd2path receives a file descriptor and a buffer together + with the buffer length. It verifies that the buffer has valid + addresses (arg[1] is the pointer to the buffer and arg[2] is + its length). Then it uses fdtochan to get the channel for the + open descriptor. The work was really done when the channel + (Cname) was built. The only thing fd2path has to do is to + extract the name (if there is any) and print it in the user + buffer. The channel name is the name used by the user to get to + the file. If the user used a relative path to open the + descriptor given to fd2path, the name of up->dot was used to + build c's name, in namec. + + Another useful system call is chdir(2) + + syschdir() Entry point for the chdir system call. Changes the current + directory. + + sysfile.c:599,610 + It simply verifies the name given, and resolves it to a channel + using namec (Note the Atodir access, that was explained + before). Then dot for the current process is set to that + channel, after releasing the reference to the previous dot. + +Pipes + + There is a system call to build a pipe. A pipe is a buffered channel + used to let two processes communicate. Surprisingly, the pipe system + call is not a real system call; I mean that although it is a system + call, it uses files serviced by a pipe device to provide its service. + The system call is provided as a convenience, although the user is + perfectly capable of using the pipe device himself without relying on + the system call. Using the device has the good thing that the user is + conscious that pipes are provided using files serviced by pipe, and + they could be even mounted through the network. + + syspipe() Entry point for the pipe system call. Creates a full-duplex + pipe. + + sysfile.c:138,146 + syspipe is called to create a pipe (see figure [230]5.4). The + pipe interconnects two file descriptors so that at one you read + what was written at the other. arg[0] is an array with space to + put the descriptors numbers in. evenaddr is used because + integers are going to be written into arg; some machines issue + alignment exceptions when you write an integer into a location + not aligned to an even address. + + CAPTION: Figure 5.4: Pipes are bidirectional channels accessed through + files provided by the pipe device. + + sysfile.c:147 + d holds the Dev entry for the pipe device, which is named #|. + sysfile.c:148 + c[0] is a channel to the root of the pipe device file tree. The + name works despite what the user did with his mount table. Here + is where the pipe was actually setup. If you read the pipe(3) + manual page, it says that an attach of the pipe device causes a + new pipe to be created. The pipe endpoints are files named data + and data1 below the root supplied by the pipe device. Different + attachments to the pipe device cause different pipes to be + created; files data and data1 would be different for each + attach. + As a side note, Plan 9 does not have the UNIX mkfifo system + call, which creates a pipe with a name in the file system. In + Plan 9, all pipes have names, even those created with pipe(2). + Execute ``bind '#|' /tmp/dir'', and then try to read/write + files in /tmp/dir. + sysfile.c:150,151 + By default, descriptors given to the user are invalid ones. On + error, the user will know. + sysfile.c:152,161 + Preparing to cleanup on errors. Descriptors are closed only if + they were open. fd holds the the descriptor numbers, which are + indexes for the Fgrp descriptor array f->fd. + sysfile.c:162,166 + Both c[0] and c[1] are channels to the root of the pipe device. + So, walk them to data and data1 to get channels to both ends of + the pipe. (why did not the author choose names ``data0'' and + ``data1'' for both endpoints?) + sysfile.c:167,168 + Important. In Plan 9, the walk merely changed the channel to + point to a different file, but you have to open the file before + doing I/O. The mode is ORDWR because Plan 9 pipes are + bidirectional. + sysfile.c:169,170 + The caller of pipe(2) is unaware of pipe files, the author + plumbs the channels to a couple of file descriptors and pipe is + done. + + Device operations + + In the code you read before, you noticed that the actual file system + work was done by device specific operations. In fact, you already knew + this since chapter [231]3, ``Starting Up''. Let's read now the code + still unread regarding devices and device operations. + + portdat.h:175,195 + The Dev structure (which you already saw), contains the + information for a known device type. Instances of Dev are + configured into devtab when compiling the kernel. The first two + fields contain the ``device character'' and the device name. + You know that kernel devices have names like ``#C'', the ``C'' + is at dc; it identifies the device type. To locate the entry in + devtab for a particular device, you only have to iterate + through it searching for an entry with the wanted dc. The name + is mostly for debugging. + Regarding device operations, they correspond to 9P messages + (read intro(5)). When a user process (or the kernel) performs a + file operation, that operation translates into 9P requests + (transactions). For example, you know that to open a file you + need to clone a channel, walk on it, and open it. These + procedures (clone,walk,open,etc.) correspond actually to + Tclone, Twalk, and Topen 9P requests. When the file server is + within the kernel, the kernel looks up the device in devtab and + calls its implementation for the request (the Dev.open, + Dev.walk, etc.); when the file server is remote, the kernel + driver for the file is the mount driver, which issues 9P + messages (Topen, Twalk, etc.). Do you get the picture? + 9P uses the term ``transaction'' for requests. So, what is each + 9P transaction for? One fine way of learning it is to look at + the implementation of each transaction for a particular device. + I'm going to use the pipe device. While you read the devpipe.c + source, you will learn what is each transaction for; and you + will see how the file dev.c provides default implementations + for most 9P operations. Such default routines are handy when a + device has nothing to do (but for replying to the request) to + service a particular 9P transaction. All devices are file + servers, and all file servers are likely to share much code; + that shared code is located into generic utility routines in + dev.c. + +The pipe device + + Initialization + + devpipe.c:370,389 + This is the ``entry point'' for the pipe device. The Dev + structure is linked into devtab so that the kernel can locate + it. The kernel device name is ``#|'', among routines linked + here, there are routines corresponding to 9P transactions. + devreset()Generic procedure to reset a device. + dev.c:62,65 + The ``reset'' procedure is not a 9P operation, but a routine + provided to ``reset'' the device to an initial state so that + its init procedure could be called. You saw how it worked for + ethernet devices while learning how the system boots. For + pipes, nothing has to be done to reset the device; and that is + very common. The dev.c file contains a devreset routine to use + as a generic reset procedure. It does nothing. Instead of + declaring an empty routine for each device without resetting + needs, this one is used. + Remember that chandevreset calls all reset procedures for + configured devices at boot time. + + pipeinit() Initializes the pipe device. + + devpipe.c:41,50 + The ``init'' procedure is not a 9P operation. It is used to + initialize the device and prepare it for operation. After init + is called, other procedures can be called. For pipes, the + configured pipeqsize parameter determines the size of the queue + used by each pipe. Should it be unspecified in the + configuration file, 256K are set for multiprocessor machines, + and 32K for monoprocessors. For multiprocessors, processes at + both ends of the pipe can execute at different processors. It + is not a problem if a process is allowed to run until it puts + 256K in the pipe, even if the reader has not read a single + byte. By giving more room to the pipe, the writer can write + more without blocking, and the reader can read more without + blocking--even if the other process is not attending the pipe. + On monoprocessors, the author thinks that it is better not to + let the process run for so long before being blocked; after + all, the process at the other end of the pipe has to use the + only processor in the system. + devinit()Generic procedure to initialize a device. + dev.c:62,70 + The default implementation (used if the device does not care + about init) is one that does nothing. + You know that chandevinit calls all the init procedures for + configured devices (after chandevreset) at boot time. + + Attaching to the server + + pipeattach() Attaches to the pipe device. + + devpipe.c:55,56 + The first 9P request issued to a file server is an attach. It + attaches a client to the file server. Any authentication is + done here. (see attach(5)). Usually, attach would just attach + to the server's file tree. However, for devpipe, attach also + creates a new pipe and attaches the client to its corresponding + file tree. To create multiple pipes, you attach multiple times + to #|. An string spec is supplied to attach. That is useful in + case a server services multiple file trees, to select one of + them. + devpipe.c:61 + devattach is a generic attach procedure that contains common + stuff for attach procedures. Both the name of the device and + spec are given to it. + + pipeattach + devattach() Generic code to attach to a device. + + dev.c:72,78 + devattach creates a new channel, c, which would point to the + root of the device file tree. + + pipeattach + devattach + newchan() Setup a new channel. + + chan.c:67,103 + newchan tries to get a channel structure from a free list found + in chanalloc (a channel allocator). Should the free list be + empty, smalloc is used to allocate a Chan, and it is linked + into the chanalloc list. Channels in use are linked into + chanalloc.list through the link field of Chan; channels not in + use (deallocated) are linked into chanalloc.free through the + next field of Chan. The fid field is given an unique value, + different from other channels in the system. chanalloc.fid + contains a number which is incremented every time a channel is + created. So, every Chan in the kernel has its own fid. The FID, + represents a file for the client in 9P. When requests are + issued from a client to a 9P file server, every file in use by + the client has its own fid. You will learn more about FIDS when + discussing remote files. By now, note how this kernel ensures + that all its channels have different fids; So, file servers + attending this kernel (including the servers within the kernel) + see different fids for different files used by this kernel. + Remaining fields of Chan are reset, but for the reference held + by whoever is allocating the channel. + + pipeattach + devattach + + dev.c:79 + The channel allocated is to be given to the client (the caller + of attach for devpipe). In the same way the client identifies + files by FIDs, the server identifies files by QIDs. A QID is an + unique number within the server, identifying a file on it. The + qid field of Chan holds the QID for the file pointed to by the + channel. In this case, it is a directory and the convention is + that directory QIDs have the CHDIR bit set. The path of the Qid + is just CHDIR and its vers is zero. + dev.c:80 + The type in the channel is used to index back to devtab and + obtain 9P procedures for this channel. The index is the one for + tc (|) as found by devno. + dev.c:81,82 + The name for the channel is an absolute path for the file + serviced. By now, it is the name for the device root (#| in + this case). + dev.c:83 + The channel returned. All this code in devattach is the typical + work that all attach routines must do. dev is giving the author + a means to share that code. + + pipeattach + + devpipe.c:62,64 + The channel is setup, but devpipe has to do its job. First, + allocate a Pipe structure. (exhausted raises an error with the + appropriate message, see proc.c:1147,1154). + devpipe.c:67,77 + Pipes have two queues because they are bidirectional, unlike + UNIX pipes. qopen creates a new queue, using the configured + size. Queues are discussed later. + devpipe.c:79,83 + path relates to the path field in the QID. It identifies a file + within the server. In this case, a pipe has two files (data and + data1). To give each file an unique path value, the author + increments pipealloc.path every time a pipe is created. + NETQID()Builds a Qid.path from two values. The macro NETQID + takes two values and builds a Qid.path field. The reason for + that is that it is handy to use Qid.path as two fields, one + specifying the file and another specifying the file type. In + this case, Qdir is used as the type for the pipe root + directory, Qdata0 and Qdata1 are used for the data files for + the pipe. By looking at this tiny field within Qid.path, + devpipe knows which kind of file is being used. Regarding the + other little field in Qid.path, specifying which file is the + QID for, the value is set to 2 x path; even values refer to one + data file for the pipe, odd values to the other. Nevertheless, + in this case the CHDIR bit is kept set (this is the root + directory for this pipe). + devpipe.c:84,85 + The aux field of Chan is provided to let the drivers place + there their state for the channel. In this case, the pipe + structure is linked there. As there are no multiple ``pipe + devices'', the device number is set to zero (another + alternative would have been to use dev to multiplex the device + among multiple pipes). + devpipe.c:86 + So, after calling attach for the device, the client (the + kernel) has a channel to the root of the specified file tree in + the server. + + Navigating + + Once the client has a channel to the root directory, the client can + move it through the file hierarchy by issuing walk requests. More + precisely, the client would clone the channel (to keep the channel to + the root intact) and then walk on the clone. + + By using walk to move a file descriptor (a channel, with a fid) to + point to a different file in the server (to change its qid), + navigation of paths can be done in a more simple way that it is done + by protocols such like NFS [[232]16] or RFS [[233]14]. For instance, + there is no need to read directory entries, nor to check that an entry + is there in the client, nor to open/close intermediate directories. + Just one walk per path component suffices. + + pipeclone() Clones a channel for the pipe device. + + devpipe.c:89,90 + pipeclone is the clone procedure for the pipe device. The + kernel calls clone when it wants a copy of a channel it has. + The procedure is supplied the original channel (c), and the new + (clone wannabe) channel (nc). It is expected to return the + cloned channel unless there are errors. + devpipe.c:94,95 + Recover the state for this channel (the Pipe structure), and + call the generic devclone procedure provided by dev.c, which + contains common stuff done almost by every clone procedure. + + pipeclone + devclone() Generic clone procedure for devices. + + dev.c:86,110 + To get a clone, first ensure that the channel is not open. + Should it be open, somebody could be doing I/O to the file and + it is not polite to mess up with the file in the mean time. As + the client in this case is the kernel, if the channel was open, + it would be a kernel bug; hence the panic. + Later, if the caller of clone did not bother to allocate a + Chan, devclone does the work. All fields are copied; but see + how a new reference is added for any Mhead structure pointed to + by mh. Besides, Chan links are kept untouched and the clone has + no name. The reason for not cloning the name is that it is + likely to be computed differently by the caller. + + pipeclone + + devpipe.c:96,109 + The pipe is locked, and a new reference accounted. (Another + client is using this pipe). By the way, the if would never be + executed because of the panic in devclone. + + pipewalk() Walks on a pipe device file. + + devpipe.c:147,151 + After cloning the channel to the root, the kernel would + probably walk on it to make it point to a different file. As + this is almost the same processing for all devices, devwalk + does all the job. The only thing devwalk has to know is how to + obtain directory entries for the file being walked. You will + understand this right now, while reading devwalk. + + pipewalk + devwalk() Generic walk procedure for devices. + + dev.c:113 + devwalk is a generic walk routine. It performs a walk to name + on the c channel. However, it does not know what is the file + hierarchy serviced by the device. Therefore, it needs some help + from the device to learn what names it is servicing. The help + comes in the form of an array of Dirtab entries, and a Devgen + procedure. + portdat.h:197,203 + A Dirtab entry contains the name and the Qid for a file. That + is mostly what is needed to scan directory entries. Besides, + file length and permissions are found here too. The directory + table supplied to devwalk is a fake one, file attributes are + not kept there; they are kept wherever the file server wants. + Of course, it is convenient to use an array of Dirtab entries + for directories, but it is not a must. + portdat.h:43 + A Devgen procedure is an iterator for directory entries. It + receives an array of Dirtab entries, and an index for a file + (third parameter). It is expected to both update the channel to + point to the i-th file in the directory table, and to fill up a + Dir structure with attributes for the file. + dev.c:118 + Back to devwalk, it first ensures that c represents a + directory. isdir raises an error when the QID has not the CHDIR + bit set. + dev.c.:119,120 + Should the name be ``.'', the walk is already done: c already + points to ``.''. The procedure returns true to indicate + success. + dev.c:121,125 + Should the name be ``..'', it is gen the one who knows how to + walk to it. The channel and the directory table are given to + gen. That is why devwalk received the table, to pass it back to + gen, to let it iterate through the table if needed. In this + case, the ``file index'' supplied to gen is DEVDOTDOT, which is + -1. The convention is that gen should walk to ``..'' when + DEVDOTDOT is given as an index. How to do that, only the device + (pipe in this case) knows. + A Dir structure is supplied to gen. Devgen routines should fill + up the Dir with attributes for the file determined by the file + index. Once gen did its job, the QID is extracted from the just + filled Dir, and updated in the channel. From now on, c points + to the file found by gen. + + pipewalk + devwalk + pipegen() Directory entry iterator for the pipe device. + + devpipe.c:112,122 + In the case of pipe, the Devgen routine is pipegen (see line + :150). Should the index be DEVDOTDOT, the file is the root of + the pipe file tree. Why? Because if file was one of the data + files, the parent is the root; but if file was the root, its + parent is also the root by convention. To fill up a Dir + structure with file attributes (which is a common job for + devices), there is a generic devdir routine. + devdir()Fills up a Dir structure. + dev.c:25,43 + devdir simply receives as parameters the qid, name, length, + owner, and permissions for the file, and puts all that + information into the Dir structure. If the channel has the + CHDIR bit set, the mode field of the Dir structure is kept with + CHDIR set. That is the convention for directories. Access time + and modification time are set accordingly with the current + time. Every time devdir fills up a Dir structure, times are + updated. The group for the file is set to eve by default. Of + course, should the device supplying the file disagree regarding + modification time or group id for the file, it can update the + Dir entry before using it. + dev.c:126,127 + Back to devwalk, the name is neither ``.'' nor ``..''. The + procedure iterates through the given tab to find the file. + Starting with directory index zero, it calls gen with + successive indexes until gen returns -1. + dev.c:128,130 + The convention is that gen should return -1 when the index + given is not valid. In this case, that means that the index is + past the entries in the directory: there are no more entries. + dev.c:131,132 + gen returned zero. That means that the entry does not exit, + however, the index is valid and no major error occurred. So, + continue iteration. + dev.c:133,138 + A valid entry was found and gen filled up dir with attributes + for the file. If the name in dir is the name to walk to, the + procedure uses the QID for the file (dir.qid) as said by gen to + make the channel point to that file. A return of true from + devwalk means that the walk could be done. Iteration is + continued (linear search) until the entry is found. + dev.c:141 + Just safety. Be sure that if you reach this line, a false is + returned to say that devwalk couldn't walk to the file. + devpipe.c:124 + In the case devwalk was called for a file not being ``.'', nor + ``..'', you saw how it called gen (pipegen in this case) to + iterate. In this case, this line is reached, and tab + corresponds to pipedir (see line :150). + devpipe.c:34,39 + pipedir has Dirtab entries for a typical pipe root directory. + It contains two entries (for two files) named ``data'' and + ``data1''. Their Qids are Qdata0 and Qdata1, but note that + these are actually ``file types'' to build the real Qids. Their + mode is 0600, which makes sense for pipe data files, and their + length is set to zero--just to give them a length. + NETID()Extracts the id from a Qid. + devpipe.c:124,126 + NETID takes the Qid's path, and extracts the file id from the + Qid path. Remember that the Qid for a pipe file keeps both the + ``type'' and the ``id'' for the file. Pipe services multiple + file trees (one per pipe), although for its clients, it is + servicing just one. The way pipe has to distinguish among + different pipes is to use the Qid path. Qid.path must be unique + for the three files used for each pipe. Let's revisit how are + Qid paths built: + + The root directory for the n-th pipe has (2 x pipealloc.path; + Qdir) as Qid.path. (cf. line :83). + + The 0th file in the pipe directory has (2 x pipealloc.path; + Qdata0) as Qid.path. (cf. line :124). + + The 1st file in the pipe directory has (1+2 x pipealloc.path; + Qdata1) as Qid.path. (cf. lines :124,126). + Just Qdir and Qdata would suffice to distinguish among + different files; because the ``id'' is different for data0 and + data1. Nevertheless, the author thought it was convenient to + have two types for the data files. + devpipe.c:127,128 + No table given, or index out of range. Return failure. + devpipe.c:129 + tab points now to tab[i], the entry for the i-th file. + devpipe.c:130 + The Pipe state for the file is recovered from the channel. + devpipe.c:131,141 + The index given by devwalk, selected an entry in pipetab. For + each entry (data0/data1) set the file length reported as the + length of the queue associated with the file. qlen returns the + queue length. The default should never execute because the + index was within range and pipetab has two entries. But just in + case something changes, the routine does its best by looking at + the length field for the file in the table. + devpipe.c:142,143 + Fill up the Dir for the file. The length was computed, the name + came from the pipetab entry for the file, as well as + permissions came from there too. Regarding the Qid, vers is set + to zero (the author does not care), and path is set by placing + in it both the Qid.path from the table (actually the file + type!) and the file id. + + Opening pipes + + The client using devpipe, after attaching to it would clone the + channel to the root and walk on it. Once the channel is positioned + into the file of interest, the device open routine is called. This + pattern of usage is common in 9P. open(2) would issue multiple + requests on its own (attach?, clone, walk, open). + + pipeopen() Open procedure for the pipe device. + + devpipe.c:181 + pipeopen is the open routine for devpipe. It receives the + channel being opened and the open mode. It should check that + permissions allow the requested open mode, and prepare the file + for I/O. + devpipe.c:185,192 + A directory is opened (the root), only OREAD mode is allowed. + If the mode is OREAD, it is noted in the channel for further + use (by I/O routines) and the channel is flagged as open. + devpipe.c:194 + An open for a data file. A process is about to read/write one + end of the pipe. p is the Pipe structure for the channel. + devpipe.c:196,203 + The process is going to use one queue. The qref array keeps + reference counts for both queues--because several processes + could open the pipe files, and these files should stay as long + as at least one process is using them. + devpipe.c:206,209 + openmode checks that omode has valid bits on it. The offset is + set to zero so that any read/write would be done at the + beginning of the file. + In fact, the pipe device ignores offsets while servicing reads + and writes because pipes are streams of bytes; as you learned + before, a file server is free to ignore offsets in read/write + requests. The only thing that matters is that the server should + offer a consistent view of its files. + + There is also a generic open routine provided by dev.c. Let's look at + it. + + devopen() Generic open procedure for devices. + + dev.c:212,251 + The gen routine is used to iterate through the directory, + searching for the file being opened. When the entry is found + (same path in Qid), the information found in the Dir structure + filled up by gen is used to check permissions (you know: + ``rwx'' bits for owner, group, others). The routine is doing + nothing but for checking that the open can be done and to + initialize channel flags and mode accordingly. + + devcreate() Generic create procedure for devices. + + devremove() Generic remove procedure for devices. + + devwstat() Generic wstat procedure for devices. + + dev.c:253,257 + pipe uses devcreate as the routine for file creation. It simply + denies permission to create files. + dev.c:287,297 + The same happens for remove and wstat (9P transactions for + removing files and updating attributes). + + Read/Write + + pipewrite() write procedure for the pipe device. + + devpipe.c:306 + pipewrite is the write procedure for devpipe. It mimics the + write(2) system call. + devpipe.c:310,311 + Interrupts should not be disabled. Looks like the author was + bitten by a bug supposedly caused by calling pipewrite with + interrupts disabled, and the author preferred to ensure that + wouldn't happen. + devpipe.c:312,317 + The code could be like it is, without line :314. However, if + CMSG is set in the channel flag, the channel is being used to + talk to a file server servicing a mounted file tree. In this + case, the system would allow the write without posting a note. + Why is this necessary? I think that the write could be done by + a server to reply to a request issued by the client. Now, the + client could have gone and its side of the pipe closed. It is + not fair to kill the server with a note in this case. + devpipe.c:319,336 + qwrite does all the job. Since only OREAD is allowed when + opening a directory, this must be a pipe data file--there is a + panic just in case. By the way, qwrite would block the process + when the queue is full because the reader is slow. + + piperead() Read procedure for the pipe device. + + devpipe.c:265,282 + piperead is the routine called for reading pipe files. Its + interface is like read(2). A generic routine devdirread is used + when the read refers to a directory, and qread is the one doing + the job of reading from a pipe (data file). qread would block + the process is there is nothing to be read in the + queue--because the writer is slow. + A write to data0 writes to q[1], and a read from data1 reads + from q[1]. Thus, what is written to data0 is read from + data1--and the other way around. + + piperead + devdirread() Generic read procedure for the device directories. + + dev.c:185,210 + devdirread is called by piperead to read from the (root) + directory. It reads an integral number of directory entries + each time. Line :191 determines the number of entries (each + DIRLEN bytes) read so far. The loop controls that at most n + bytes are placed in d, and also increments the file index for + gen. Gen fills up dir, and convD2M places dir information into + d in a machine-independent format. + + There are two read/write routines that do not correspond with 9P + requests. They are bread and bwrite. Their purpose is to read and + write blocks of data. By using specialized versions of read and write + that operate on blocks, block I/O can be made more efficient. This is + mainly used by the code in /sys/src/9/ip, which reads/writes blocks of + data received/sent through network devices. + + pipebwrite() Block write procedure for the pipe device. + + devpipe.c:338,368 + The routine should write the block bp. It is like pipewrite, + but qbwrite is used instead of qwrite. The ignored long + argument is an offset--ignored because pipes are FIFO. + + devbwrite() Generic block write procedure for devices. + + dev.c:276,285 + There is a generic devbwrite, which simply adapts the request + to the device write procedure. It also releases the block + (because the block is usually allocated by the source of the + data and deallocated by the drain of the data). Pipe does not + use this procedure. + + pipebread() Block read procedure for the pipe device. + + devpipe.c:284,299 + The routine is like piperead, but uses qbread (not qread) to + read pipe data files. To read the directory, a generic devbread + routine is used. + + devbread() Generic block read procedure for devices. + + dev.c:259,274 + The generic devbread allocates a Block, (releasing it on + errors) and calls the device specific read routine to fill up + the Block. In the case of data files, the block comes from the + queue. This is simply an adaptor to the device read routine. + + Attributes + + pipestat() Stat procedure for the pipe device. Gets file attributes. + + devpipe.c:153,175 + stat is the 9P request to obtain file attributes. wstat allows + to update attribute values, and you now know that this is not + allowed for pipe files. Depending on the Qid, devdir is called + to fill up DIRLEN bytes into db. The structure is the same that + is obtained by reading the directory. Qlen is used to provide + lengths for pipe data files. + + devstat() Generic attribute read procedure for devices. + + dev.c:145,152 + There is a generic devstat routine (not used by pipe). It uses + again a Dirtab and gen to locate the file of interest (same + Qid), and fill up the stat buffer (db) with file attributes as + filled up by gen in dir. + dev.c:153,171 + The index was out of range--which is the case when the channel + points to the directory and not to any file on it. If the Qid + is for a directory, a name is given to it when the channel has + no name, the name is set to ``/'' when the channel name is + ``/'', and if the channel name is not ``/'', the name is set to + the last name after the the last ``/''--i.e. elem is the file + name for the path in the channel name. If it was not a + directory, it is a true error. + dev.c:174,181 + The file was found--Qids match. + +Remote files + + What you have read about file systems works without depending on where + is the file server (where are the files). The kernel (e.g. for Fgrps + and the Pgrps) use channels to represent files being used, and + channels use device operations to implement the functionality needed + to operate on files. Until now, you have seen how all device + operations are called by procedure calls dispatched by the device + type. For remote files, the system works mostly in the same way; the + mnt(3) device implements 9P operations for remote files. + + Initialization + + mntreset() Reset procedure for the mount driver. + + devmnt.c:64,71 + mntreset is the reset procedure for mnt, (:920,939). It is + initializing the mntalloc global, which is an allocator for Mnt + structures (:portdat.h:241,253) used to service remote mounts + (Everything else in mntalloc was set to zero by the loader). + Besides, it calls cinit to initialize a cache (caching is + discussed later). + + There is no init procedure (the generic null one is used). + + Attach + + sysmount + bindmount + mntattach() Attach procedure for the mount driver. + + sysfile.c:652,656 + When mount is used instead of bind, the file tree bound is + serviced behind a file descriptor. That means that 9P + transactions must be issued through its channel to operate on + the file tree. The file server can be a local user process, a + remote user process, or a remote kernel used as a file server; + for the local kernel, it doesn't matter. + Remember that bogus contains a channel to the server, the spec + for the file tree requested, and an indication of whether files + are being cached or not; everything attach needs to get in + touch with the file server and attach to it. The casting is + needed because attach should receive a character string, but + mntattach knows it receives an structure and not a string. + By the way, mount is the only way to attach the mount driver, + as attach is forbidden from ``#M'' paths. Every time you attach + to it, you are attaching to one particular file tree, which is + in fact serviced through the network. + devmnt.c:73,86 + mntattach knows it receives a bogus structure and recovers it + from the pretended string spec. Perhaps a common header (or a + comment saying who else is using the structure) would help to + prevent errors. The c channel corresponds to the file + descriptor being mounted. A 9P server sits at the other end of + the channel. + devmnt.c:88,109 + The mntalloc list is scanned, looking for a entry (m) with the + same channel and a non-zero id. That list contains entries used + to handle each mounted file tree. If such an entry is found, it + is locked and checked to be still valid (ref). The checks for + id and c are repeated because the lock was not held before--to + avoid blocking other processes using the entry. + This loop is an attempt to share the entry (when the same file + is being mounted several times); In this case a reference is + added, and another channel obtained using mntchan. That channel + is the one to be used for the root directory of the file tree. + The procedure mattach issues a 9P attach transaction to the + remote file server, and the CACHE flag is cached in the + channel. You will learn soon how mntchan and mattach work. + Noticed how eqchan is not used to compare channels in mntalloc? + The mount driver is interested on finding an entry with exactly + the same channel structure. + devmnt.c:111,124 + No entry with the same channel, so allocate a new entry from + either the free list of mntalloc or from fresh new memory (the + list used now is mntfree and not list). A new id is allocated + and placed into the Mnt structure created. Can you see how id + is non-zero, and mclose resets it to zero? The id check at :90 + is for safety. + devmnt.c:127,131 + Starting to initialize the Mnt for this mount. The channel used + to talk to the server is recorded in m->c (So the loop used + above to locate an Mnt entry was searching for an entry using + exactly the same 9P connection to the server). The flag CMSG in + the channel states that it is being used to talk to a remote + file server. Although the descriptor supplied by the user was + closed by sysmount, it could be duped, so the flag in the + channel is needed to prevent interferences in the 9P + conversation. + Remember the check at sysfile.c:85,89? When fdtochan is used to + get a channel for a file descriptor, and it is being used by + the mount driver, an error is raised. The mount driver is very + jealous about this channel. That happens only when a true + chkmnt is given to fdto2chan, which happens when sysread9p, + sysread, syswrite9p, syswrite, sseek, and sysfwstat call + fdtochan. Routines reading, writing or updating the state are + forbidden for channels used by the mount driver. + devmnt.c:132,140 + blocksize in m is set to the size for data blocks exchanged + between the mount driver and the file server. Unless the spec + string given to mount was mntblk=n, it is set to MAXFDATA. In + this case spec is set to null, not to disturb the remote + server. Perhaps a writable file for the mount driver would be + better than using the spec string; although the method used by + the author allows different block sizes for different mounts. + devmnt.c:141 + All flags are kept in Mnt flags, but for MCACHE, which is kept + in c. Surprisingly, only the MCACHE flag was set in bogus.flags + by bindmount. Therefore, m->flags is now zero. + devmnt.c:143 + Right now, the channel is still there, but when bindmount + closes it it could go away. This new reference keeps the + channel alive. + devmnt.c:149 + mntchan returns the root channel to be given to the caller. + + sysmount... + mntattach + mntchan() Returns a channel to the mount driver impersonating the + channel to the remote file tree. + + devmnt.c:185,196 + It uses devattach to build a channel for a directory in the #M + device. This is very important. The user thinks it got a + channel to the remote root directory, but he got a channel to + the mount driver instead. The real channel to the server (not + to the root, but to the server) is kept by the mount driver, as + shown in figure [234]5.5. An important thing here is that dev + in the channel built is set with an unique id. This id is used + by the mount driver to recognize that mount entries remain + valid. + + CAPTION: Figure 5.5: The mount driver sits between the server and the + client. The kernel uses channels serviced by the mount driver. + Requests for these channels are implemented speaking 9P with the file + server. + + devmnt.c:150,157 + Note how to cleanup on errors, the ``cclose'' is done. The + recursive call would be to mntclose, which would try to use the + channel to send a Tclunk request. That would make no sense at + this point. But perhaps a channel flag could be added to the + channel so that mntclose would do nothing to a channel not yet + set. + devmnt.c:159 + Starting to speak 9P. mattach performs a 9P Tattach transaction + (client side). If it finishes without raising an error, the + attach RPC has been done, m->c is a channel to the server, and + c is a channel to the mount driver. + devmnt.c:170,177 + If the if is entered, you knows that: + 1. + The channel to the server (m->c) is a channel serviced by + the mount driver. You know this is the case because the + channel to the server has as type the index for the mount + driver in devtab. + 2. + The file server at the other end of the channel is + exportfs. Tricky!!. You know this because in + /sys/src/cmd/exportfs/exportsrv.c:574, exportfs is + clearing the CHDIR bit from the QID for the served + directory (c->qid). That should never happen because the + server is servicing its root directory. However, exportfs + clears that bit, and the mount driver notices that, does + this hack, and repairs the missing bit at line :172. + Perhaps it would be more clean if the Rattach reply could + carry a string of information back to the client--in the + same way the Tattach carries an spec string. Nevertheless, + the protocol and the code are cool, aren't they? + What is the hack doing? Well, the Mnt entry for c is closed, + i.e. not going to behave as if the remote c was mounted through + m->c, which it was. The mntptr (which points to the Mnt + structure) of the client channel (c) is set to point to the one + linked at the server channel. That means that mc->mntptr is + going to be shared among all file trees serviced through mc. + Should this be removed from the kernel, requests for the tree + being mounted would be translated to 9P transactions by this + mount driver, and such transactions would be written to + c->mchan (which is m->c here). Now, to write the 9P request r + to a file serviced by the mount driver, a 9P request s has to + be issued to m->c->mchan, with the r request being the data. + That makes no sense, when you could speak 9P right to the final + server[235]9.1. Hence the hack. This is one of the few places + in the kernel source when a trick which is not clearly exposed + in the system interfaces is being used to prevent the system + from doing a silly thing. + Now, what if mc is remote (serviced by the mount driver), but + the server is not known to be exportfs? The author cannot + assume that the remote server would multiplex its connection + among trees mounted from it, so the best the mount driver can + do is to use 9P requests (to the server of the channel for the + file server) to write 9P requests for the channel (to the file + server). + + sysmount... + mntattach + mattach() Uses a Tattach to attach to the server file tree and + initializes the channel to point to its root directory. + + devmnt.c:198,210 + We still have pending the discussion of mattach, which + allocates an Mntrpc structure to manage the RPC done by the + mount driver. The structure is deallocated on errors. + devmnt.c:8,22 + An Mntrpc contains among other things two Fcall fields (request + and reply) which are the request message and the reply message + for the RPC (see /sys/include/fcall.h). Those are 9P + transactions and replies. + devmnt.c:212,215 + The request is a Tattach. The fid for the Tattach is the fid in + c. Each kernel channel has its own fid (chan.c:81), so there is + no ambiguity regarding which client ``file descriptor'' would + point to the root of the remote tree. The user name is that of + the current process (can user contain null characters?). + devmnt.c:216,218 + Fields ticket and auth are set by authrequest to authenticate + the client to the server. m->c->session is the structure used + to maintain authentication/encryption information for the + session maintained through the channel. m->c is the channel to + the server, which is not c, that is the channel for the client. + The value returned by authrequest is used later by authreply to + check that the reply received for the request is valid and not + a fake one. Should it not pass the security check, authreply + raises an error. mountrpc does the actual work of sending the + request and receiving the reply. + devmnt.c:220,226 + The channel QID is set from the qid in the reply (so that it + really points now to the server root file). Besides c.mchan is + set to the channel for the server, now that it is attached. + Future requests for c would use its mchan field to issue RPCs. + mquid also holds the QID for server's root directory. + + RPCs + + But how is the RPC done? + + mountrpc() Performs an RPC for a mounted file tree. + + devmnt.c:607,631 + mountrpc issues the request in r and receives any reply for it. + It is actually a wrapper for mountio, which does the job. First + it sets the reply tag and type to poisoned values, in case + anyone checks them before the reply arrives. Then mountio does + the job. Finally, the reply type is analyzed: an Rerror causes + a raise of the error reported (note that strings are + portable!); an Rflush interrupts the request; an Rattach + (Tattach+1) returns without errors; and everything else should + not happen. + + mountrpc + mountio() Performs I/O to issue a 9P request and receive the reply. + + devmnt.c:634 + m is used to manage the remote mount point and r is the RPC to + be done. + devmnt.c:638,646 + The while restores the error label after an error is raised. + The loop body executes each error, (unless the error is + re-raised by nexerror). Ignore this by now. + devmnt.c:648,652 + All RPCs r keep in r->m a link to the mount entry they are for. + Besides, the mount entry keeps in queue a lists of RPCs being + done. The list is done through the list field of Mntrpc, as + shown in figure [236]5.6. + + CAPTION: Figure 5.6: Mntrpcs are used to maintain the state for + ongoing RPCs for a mounted file tree, represented by Mnt. + + devmnt.c:655,657 + The server and client machines could have different + architectures. convS2M packs the request into the buffer at + rpc, in a machine independent format. The buffer at rpc is + allocated by mntralloc with MAXRPC bytes, which is the limit + for a message. The panic shouldn't happen, but just in case 9P + is changed and convS2M is not updated, let the author know. + devmnt.c:658,664 + Some times, the channel used to talk to the server is local + (e.g. the file /srv/kfs is a channel to the local KFS server). + In this case, the channel m->c is not serviced by the mount + driver and the request would be serviced by the device specific + write (:662). But some other times, the channel used to talk to + the server may correspond to a file which is mounted using the + mount driver (e.g. /n/remote/tmp/pipe). If the channel to the + server corresponds to a mount driver channel, the rpc buffer is + written using mnt9prdwr. For mount driver channels, the device + specific write is not called. Why does the author do so? The + answer relates to message sizes as you will learn later. + devmnt.c:665,666 + stime keeps the time when the request was sent. The Tattach is + now traveling to the file server and stime has the current + time. n bytes were written to the server. + devmnt.c:669,681 + The routine did set rip (reader in progress) to nil before. So, + unless other process changed the state in m, rip is nil and the + loop is broken at line :672. + If no process is reading a reply for this mount point, the + current process is the one reading. From now on, other callers + of mountio would notice that rip is not nil, and enter the + loop. They will stay in the loop until the process in rip stops + reading. Instead of spinning all the time, sleep is used to + block them until rpcattn says that r->done or there is no + r->rip process. So, processes awaiting for RPC replies sleep + and read one at a time. r->r is the Rendez used to sleep. In + figure [237]5.6 you can see a process servicing reads while + another is awaiting its reply. + devmnt.c:683,686 + done is set to false by mntralloc, it is set to true when the + RPC should be considered to be done. So, unless the RPC + finished, call mntrpcread and mountmux. + The first process doing an RPC on m is calling mntrpcread and + mountmux, and remaining processes are looping/sleeping waiting + for their replies. + + mountrpc + mountio + mntrpcread() Reads from the 9P channel until gets a reply message. + + devmnt.c:692,711 + mntrpcread loops until a valid 9P reply message is read from + the channel to the server. As it happen with write, mnt9prdwr + or the device specific read is called depending on whether the + channel to the server is a mount driver channel or not. Any + reply message is read into the rpc buffer of the Mntrpc--now + that the request was sent, the buffer can be reused for the + reply. Lines :708,709 call convM2S to convert the machine + independent reply found at rpc into a reply structure. If the + conversion fails (the reply message is not a 9P message), the + loop continues and another reply is read. The mount driver is + ignoring invalid messages. Once a valid reply is read, the + return executes and mountmux is called. + + mountrpc + mountio + mountmux() Multiplexes the 9P channel among multiple RPCs. + + devmnt.c:728,763 + mountmux multiplexes the channel to the server among multiple + processes doing RPCs. m->queue was a list of ongoing RPCs + through m. The list is searched for an RPC whose request had + the tag found in the reply just read. If you read intro(5), you + know that 9P replies carry the tag of their request message. If + no RPC in the list has a request with the same tag of the + reply, no one is waiting for this reply. In this case the + routine completes without doing anything, and mntrpcread would + run again and read another reply message into the rpc buffer. + The reply (without a request) has been ignored. + devmnt.c:740,749 + If the reply message is for the RPC being done by the process + that called mountmux (the first reader), r would be equal to q + (the node with matching tag). If r and q differ, the reply is + for some other process. In this case, the rpc buffer for the + current process is exchanged with the rpc buffer of the RPC + replied. Besides, the reply structure for the process replied + is set to point to the reply structure containing the unpacked + reply. In this case the current Mntrpc has an empty buffer in + rpc to receive another reply. + This buffer exchange is very important to avoid fragmentation + and also to improve performance. The author tries not to + allocate/deallocate buffers unless it is really necessary. + devmnt.c:750,759 + done is set in the Mntrpc whose reply arrived. If it was + another process, line :757 would awake it; then it would notice + that done is true and pick up its reply. If it was the current + process, our done is set. + + mountrpc + mountio + + devmnt.c:683,686 + If the reply was for us, the loop breaks. In any other case, + the process keeps on reading from the channel and servicing + replies to waiting processes (including himself). + Can you see how when one process has to do some work for + himself it tries to do useful work for others too? It would be + silly if all processes were spinning trying to read from the + channel. + devmnt.c:675,679 + Another processes awaken would check its RPC done field. Should + it be true, the process has a reply in r, and mountio returns. + Should it be false, the process re-enters the loop and sleeps + again if there is another process reading from the channel + (rip). If there is no other process reading (the reader got its + reply and its mountio returned), the process breaks the loop + and becomes the channel reader, servicing replies for others. + devmnt.c:687 + Unless the reply to the RPC was serviced by another process (a + channel reader on our behalf), mntgate is called. + + mountrpc + mountio + mntgate() Elects a new reader for the channel. + + devmnt.c:713,726 + What happens is that we were the channel reader (servicing + requests to others), but our reply finally arrived and we are + leaving mountio. Another process must read the channel, if + other RPCs are pending. mntgate awakes the first process found + with a pending RPCs in the list. It becomes the reader (see + line :719). + + mountrpc + mountio + + devmnt.c:638,646 + Should an error occur during all this time, the process calls + mntgate (if it's the reader) to let other process take its + place, because due to the error the current process can abort + the RPC and return. But how are errors handled? + Consider that an Emountrpc is raised at line :663, after + getting back to :638, the loop body is entered. The error is + not Eintr, therefore an mntflushalloc is done on r. + mntflushalloc()Allocates a Flush request for a failed RPC. + devmnt.c:769,784 + mntflushalloc allocates an Mntrpc for a Tflush message, and + links r (the RPC suffering the error) in the flushed field of + the Tflush Mntrpc. A list of flushed requests is being built + through the flushed field of Mntrpc. The field oldtag of the + Tflush is set to the tag of the RPC failing. If the failing + request was a Tflush, the RPC failing was the one that caused + the Tflush. + devmnt.c:646 + So on a error, mountio runs again with the request being a + Tflush. If an RPC fails, a Tflush is sent to the server. If the + Tflush fails, another Tflush is sent. All those Tflush are for + the (oldtag) RPC that failed. If the Tflush can proceed (the + server is running and serviced the Tflush), either :677 or :689 + call mntflushfree. + mntflushfree()Releases flushed RPCs + devmnt.c:793,808 + mntflushfree removes from the RPC queue (mntqrm) any undone RPC + flushed by r (a Tflush), and releases the structure (mntfree). + The reply is set to Rflush, because mntqrm sets the done field + of the RPC to true--the affected process might check done in + the mean time, and it should notice that no actual reply + arrived. + devmnt.c:641,644 + Should the first Tflush abort with an error raised, another is + sent. New Tflush requests are sent until an Rflush is received + or an Eintr error is raised. In the RPC is interrupted, any + flush request is released and the interrupt error re-raised. + + mountrpc + + devmnt.c:616,631 + The RPC finished (note the Rflush case). Only if the + transaction got a non-error reply, mountrpc finishes without + raising an error. + + Using remote files + + After an attach is successfully done, the client has a channel to the + mount driver, which from the client point of view is pointing to the + root directory of the remote file server. Typically, the next things + done by the client are clones and walks to navigate the mounted tree. + + cclone + mntclone() Clones a channel for a remote file. + + devmnt.c:228,229 + The clone done by the client is done by cclone, which calls to + the device specific clone: mntclone. + mntchk()Checks that the file is still mounted. + devmnt.c:235 + mntchk (devmnt.c:883,897) checks that c->mntptr points to an + Mnt whose id is not 0 (still allocated) and is less than the + dev in the channel. Line :192 sets the ``device number'' for + the channel to the Mnt id. If the check fails, either the Mnt + has been released (id set to zero at :402) or it has been both + released and reallocated for a different mount (whose id would + be bigger than the copy kept in the channel dev. + All mount driver device operations for a remote channel use + mntck to check that the connection is still alive. + devmnt.c:236 + The routine allocates the RPC structure, as it was done for + mntattach. + devmnt.c:237,240 + clone can be called with or without the ``cloned channel'', so + better be sure that mntclone has an nc. + devmnt.c:241,246 + Release the RPC on errors, and nc if it was allocated by + mntclone. + devmnt.c:248,251 + A Tclone is sent and the reply is received (or an error + raised). newfid is the FID for the clone, which was set when + the clone channel was created. devclone()Generic procedure for + cloning channels. + devmnt.c:253 + devclone does the job of copying the state in c to nc. The RPC + was just to let the file server know that newfid should be + understood as another ``file descriptor'' pointing to the file + where fid was pointing to. + devmnt.c:254,255 + What? That was done by devclone, but it does not hurt. As + another channel (nc) is using the Mnt for c, count one more + reference. Even if unmount is used, Mnt will not go away until + its reference count gets down to zero--because all channels + going through it have been closed. + devmnt.c:257 + To keep the compiler happy--alloc is used even if no error is + raised. Otherwise, the compiler might issue a warning. + + walk + mntwalk() Generic walk procedure for devices. + + devmnt.c:263,285 + Regarding walks, you now how the global namec and walk routines + work. When the device specific walk routine is called, mntwalk + executes. It issues a Twalk RPC, so that c would refer to the + file named name, within the directory pointed to by c-i.e. + within the directory for c->fid. After the Twalk is sent, and + an Rwalk is received, the QID from the Rwalk is set in the + channel. This kernel now knows that c points to the file + represented by the new QID, and the server knows that c->fid is + now pointing to that file. + + File attributes + + mntstat() Stat procedure for remote files. + + devmnt.c:287,307 + mntstat issues a Tstat transaction when an stat operation is + done on the remote file. It works like clone or walk. The + different thing is the call to mntdirfix with both the + attributes read for the file, and the channel for the file. + mntdirfix()Fix attributes for remote files. + devmnt.c:900,909 + mntdirfix changes some attributes read, to reflect that the + file is serviced by the mount driver. In particular, it writes + in the last two `shorts' of dirbuf, the letter for the device + (M) and the mount id. Although the stat(5) manual page states + that those two shorts are for kernel use, they are used + (/sys/src/libc/9sys/convM2D.c) to report the device type and + device number for the file (Can you guess where does the ``M'' + listed by ls come from?) + + mntwstat() Wstat procedure for remote files. + + devmnt.c:439,457 + mntwstat is also similar, but it issues a Twstat instead. + + Open and close + + mntopen() Open procedure for remote files. + + devmnt.c:309,337 + The QID is set from that in the reply (because the server could + have created a new file), the offset is reset to zero, and the + channel is flagged to be open. Lines :333,334 report to the + cache that the file is in use for I/O--if the file is to be + cached. That is to give the cache an opportunity to invalidate + old versions for the file and do other things. + + cclose + mntclose() Close procedure for remote files. + + devmnt.c:427,431 + This is the device operation called by cclose when the last + reference to the channel goes away. It issues a Tclunk request + to let the server know that the fid is no longer in use. + + cclose + mntclose + mntclunk() Issues a clunk RPC. + + devmnt.c:368,388 + There is no close in 9P. mntclunk issues a Tclunk, or a Tremove + is the file is being removed (devmnt.c:433,437). Seems that + mntclunk is being reused to issue both kinds of transactions. + + Read and write + + The actual device specific routines are mntread and mntwrite, but if + you look at read9p(2), you will notice that to encapsulate 9P on 9P + without problems because of the maximum message limit, read9p and + write9p have to be used to write 9P requests to a file serviced + through 9P. + + sysread... + mntread() Read procedure for remote files. + + devmnt.c:466,500 + A read to a file serviced by mount driver leads to mntread as + the device specific read procedure. cache is set if the channel + has the CCACHE bit set (i.e. if it comes from a tree mounted + with MCACHE) and it is not a directory. Caching file contents + is one thing, but caching directory entries is one of the + things that makes distributed file systems complicated (race + conditions, too much locking for clients using entries etc). + Plan 9 sidesteps that problem by not caching directories. After + all, the design of 9P (i.e. walk) allows the client to walk + paths without needing to cache directory entries. This is also + good in that if the file server changes its mind regarding + which files exist, its clients would know without any problem. + If the file is cached, the read is serviced from the cache by + cread. If the bytes cached (nc) do not suffice to satisfy the + read request (n bytes), a Tread is issued to read the bytes not + kept in the cache. cupdate updates later the cache with the + bytes read by the Tread. Besides, the device type and number + for any directory entries read are set by calls to mntdirfix. + By making directory reads return an integral number of + directory entries, processing of entries is greatly simplified. + Compare the routine with the one needed in case Tread could + return any number of bytes. + + syswrite... + mntwrite() Write procedure for remote files. + + devmnt.c:508,512 + A write is serviced by issuing a Twrite request. Both Treads + and Twrites are serviced by mntrdwr. The author reuses code as + much as he can: reads and writes have much in common. + + syswrite... + mntwrite + mntrdwr() Issues Tread/Twrite RPCs. + + devmnt.c:552,565 + either a Tread or a Twrite (type) on the channel. Note the + checks for the mount point and caching. + devmnt.c:566,602 + The routine loops sending Treads/Twrites, with the buffer for + the request being the buf given as a parameter. cnt is set with + the number of bytes read/writen. + devmnt.c:576,582 + One fine reason for looping. The caller could want to + read/write more than blocksize bytes (MAXFDATA), in which case + multiple Tread/Twrite must be issued for at most blocksize + bytes each. + devmnt.c:584,587 + Will not read (write?) more bytes than requested. + devmnt.c:589,592 + The only difference between read and write; not enough to + justify two different routines. For reads, copy the data read + into the user buffer. For writes, let the cache know of the + bytes writen to the file. + devmnt.c:596,601 + Next time, read/write past the bytes read/writen. The procedure + adjusts the file offset and number of bytes processed (cnt). + The loop continues until n is zero, which means that cnt is the + initial value of n; or until read/write could not service as + many bytes as requested (no more bytes to read/disk full); or + until a note has been posted for the process. + + syswrite9p + mntwrite9p + mnt9prdwr() Reads/Writes 9P requests (encapsulated in 9P). + + devmnt.c:515 + mnt9prdwr implements both mntread9p (devmnt.c:459,463) and + mntwrite9p (:502,506); it is also used by mntrpcread and + mountio to read and write 9P requests. It is not a mnt device + specific procedure, but a generic 9P tool. + The sysread9p and syswrite9p system calls call mntread9p and + mntwrite9p to do the work when the channel to the file server + is serviced by the mount driver. Otherwise, sysread9p + (sysfile.c:335,372 and syswrite9p (sysfile.c:414,441) call the + device read/write procedure or unionread as they should. + devmnt.c:521,525 + At most MAXRPC-32 bytes read/written (and for write this limit + should not be ever reached). The Tread (or Twrite) is sent as + usually and the reply processed as usually too. So, what's the + difference with respect to mntrdwr? First, no cache is ever + used (would you cache a connection to a server?); Second, the + routine does not loop, and it reads/writes a single chunk of at + most MAXRPC bytes. The routines transmit a 9P message verbatim. + If you compare sysread9p and sysread, you will notice how in no + case the the mount driver device specific procedure is called + to read the 9P request, and the same happens to syswrite9p and + syswrite. Besides, note that mntrdwr uses messages of blocksize + length (which can be much lower than MAXRPC) while mnt9prdwr + uses messages of at most MAXRPC bytes, independently of the + configured blocksize. Perhaps both routines could be unified + into a single one, but the author preferred to keep them + separate. + + Caching + + In the third edition of Plan 9, authors considered that it was + important (due to performance reasons) to cache files mounted from + remote file servers. That can save many 9P transactions by satisfying + reads and writes from a local cache in the client kernel. The + implementation stands at cache.c. + + In this section, you will be reading the code related to caching in + the kernel. Besides a kernel cache, Plan 9 has a user-level program + called cfs (see cfs(4)) that caches remote files. cfs is started at + boot time and services reads from a local cache (kept on a local + disk). This is interesting when it is better to read files from the + local disk than to read them from the network. Surprisingly, this is + not always the case, because when you have a fast network and a fast + file server node (plenty of memory) it can be much faster to read a + file from the network than reading it from the slow local disk. + Nevertheless, for slow network connections the performance improvement + can be dramatic. + + Regarding the kernel, cfs is just a ``remote'' file server. Therefore, + in what follows, I focus just on the caching done by the kernel. + Figure [238]5.7 shows how all the pieces fit together. + + CAPTION: Figure 5.7: Caching remote files. The best thing (1) is to + keep them cached in kernel memory. The next best thing (for slow + connections) is to keep them cached in a local disk (2). Finally, you + always have the network (3). + + chandevreset + mntreset + cinit() Initializes the kernel cache for remote files. + + cache.c:105,127 + You already know that cinit is called by mntreset at boot time. + It initializes the cache global (:39,47) by allocating NFILE + Mntcache entries, double linking them through next and prev + fields using head and tail as the list header. xalloc is used, + and not malloc. When the machine is plenty of memory (more than + 200MB), the maximum number of bytes to cache in a file + (maxcache) is not set to its usual value (MAXCACHE) but to + 10 times more. + +Caching a new file + + sysopen... + mntopen + copen() Prepares a cached remote file for I/O. + + cache.c:210 + The cache starts to work when copen is called. A copen is meant + to prepare the cache for I/O on a file. It is the mount driver + that calls copen when a remote file is being opened or created + (i.e. before doing any I/O on it). By ``remote'' you should + understand ``not in kernel'' now. Even if the file is serviced + locally by a user program, caching it can avoid unnecessary + data copies and context switches. + The cache does not keep copies of intermediate directories used + to walk to the files of interest. Therefore, cache memory is + used just for files being really used. The user controls which + file systems should be cached (i.e. by means of the MCACHE + flag). + cache.c:216,217 + The mount driver checked the CHDIR bit, but the author ensures + that it is innocuous to call copen on a directory. + Plan 9 does not cache file attributes (walk works well enough). + The alternative would be to cache attributes (including + directory contents) and perform walks locally. However, this + would require that all contents of all intermediate directories + walked be sent to the client. Moreover, this would introduce + severe coherency problems (all file server clients should see + the same set of files, with the same attributes). + cache.c:219,223 + Entries in the cache are linked at NHASH hash buckets (:40,47). + The hash function is a modulus on the channel qid.path. + Multiple entries are linked at the bucket through the hash link + of Mntcache. The routine searches the hash bucket for any entry + for the same file. The check is done using qid.path, dev, and + type fields of Mntcache, which keep the qid.path, dev and type + fields for the cached file. If multiple channels point to the + same file, these fields would be same in all of them. vers is + not compared. The cached file could be a previous version of + the file, but it would still be its cache entry. + Figure [239]5.8 shows the structures involved. + + CAPTION: Figure 5.8: Caching for remote files. Mntcache structures are + caching one file each. They are kept in an LRU list and rely on + Extents, which use kernel pages, to cache file contents. + + cache.c:224 + An entry found. The mcp (Mntcache pointer) of the channel is + set to point to its cache entry; read and write procedures can + avoid scanning the whole cache to lookup the Mntcache for the + channel. The assignment is needed because multiple channels + could be opened for the same file. All of their mcp fields + would have the same value after copen. + ctail()Sets an Mntcache at the tail of the LRU. + cache.c:225 + Remember that Mntcaches are double linked on a queue starting + at Mntcache.head and .tail. ctail (:182,207) unlinks the node + given from the list (hence the double links) and links the node + at the tail. By doing so, the file last opened is found last on + the list of entries. Probably, the author would reclaim cache + entries starting from the head of the list. It makes sense not + to reclaim this entry because it has been just opened, and is + likely to be needed soon. + cache.c:226,235 + Once that the entry is placed on the list, the lock for the + cache can be released. If vers (also copied in the Mntcache) is + older than it is in the channel, the file has changed and cache + contents are useless. The vers field in Mntcache is updated + whenever new file contents are written through the cache. The + routine cnodata does the job of disposing any (useless) cached + bytes for the file--more soon. The cache is prepared to service + the file. + One quick note about vers. vers in the channel is updated + whenever 9P requests carry back a QID for the file. If other + nodes are using the (cached) file too, it could be that the + cache contents are actually out of date, and the kernel + wouldn't notice. The actual responsible for this lack of + coherence is the user, who mounted the file with caching, or + the server owner, who did not set the OCHEXCL bit in the file + being cached. To maintain a set of distributed caches in + coherent state is just too expensive and complex. The tools the + author gives you allow you both to cache files and to use them + coherently, you only have to use the tools in the right way. + Other distributed file systems tried to do distributed caching, + but they either supplied ``session coherence'' (i.e. only after + a close can others see our changes) or were so complex that a + node failure could bring the whole system down. + cache.c:239,248 + No Mntcache entry found for the file. Should use one of the + existing entries to service the file. The hash bucket for the + head of the Mntcache list is searched. If the head entry is + there, it is removed from the hash list. You should note here + that it is the head of the list the one reused. A file could be + loosing its entry in favor of another one. You should note also + that used entries are linked into the hash bucket (hashing with + the QID). + cache.c:250,252 + The old file (if the entry was used) is forgotten. Now this + entry is for the file represented by the channel. + cache.c:254,257 + The entry is linked into the hash bucket for the c channel, + where it belongs now. ctail is used to move the entry to the + tail of the list, as it has just been used. By allocating from + the head, and moving the entry to the tail whenever it is used, + the author is doing a ``Least recently used'' policy to + maintain cache entries. + cache.c:259,269 + Finally, mcp in the channel is set to the entry allocated for + it and any extent linked into the Mntcache (which would be for + the previously cached file) is released. The cache is unlocked + as soon as no pointer is being moved. The entry has to be kept + locked because extents are being released. + + Extents + + copen + cnodata() Invalidates a cache entry. + + cache.c:166,180 + We had pending the discussion of cnodata. The cache does not + cache bytes, but Extents. (cache.c:16,24). An Extent is a len + bytes portion of the file starting at start offset. All cached + extents for a file are linked through their next pointers, at + the list field of the file's Mntcache. The routine is simply + calling extentfree for the whole list. + extentfree()Deallocates an extent. + cache.c:63,71 + extentfree is releasing the extent. It links the extent into + the head of the extent cache (:50,56). The next time the cache + allocates Extents, the ones from the ecache.head will be + reused. extentalloc()Allocates an extent. + cache.c:73,102 + Initially, the ecache has all its fields set to zero by the + kernel loader; the first time extentalloc is called, it would + notice that the free list (head) is empty, and allocate NEXTENT + extents. + The cache could do the same for the Mntcache entries; or + alternatively, cinit could also contain lines :81,92. One + reason the author could had to initialize extents this way, is + that the user could never use the MCACHE flag for mounts, and + the cache would never be used. But in that case, there is no + need to keep Mntcache entries allocated. + The actual allocation of the extent is done at lines :95,98. + The routine clears the contents of e (security first!). + +Using the cached file + + The next time the cache works, is when mntread calls cread + (devmnt.c:480) and cupdate (devmnt.c:489), and when mntrdwr calls + cwrite for Twrites (devmnt.c:592). + + Reading from the cache + + sysread + mntread + cread() Services a read from the cache. + + cache.c:288 + You know cread is called to read from the cache instead of + using Treads, when feasible--i.e. when the cache has the bytes. + cache.c:297,298 + off is the file offset where to read and len is the number of + bytes. As only the initial maxcache bytes for the file are + cached, cread ignores any request which passes that limit. + Perhaps the condition is too strong, as off could be below + maxcache and part of the len bytes could be cached. + cache.c:300,302 + Either the mcp has the Mntcache to use, or it is nil--stating + that the channel is not being cached. + cdev()Checks that the cache is still for a channel. + cache.c:304,308 + cdev tells whether the entry is valid as a cache for the given + channel (:273,285). It checks path, dev, type, and vers. + Mntcache entries are stolen from the head of the LRU list. The + entry for the channel could have been reused and the only way + to know is to check these fields. (The alternative would be to + iterate through channels, or to link channels using an Mntcache + entry, which is more complex and inefficient). + When an Mntcache is stolen from a channel, that channel remains + uncached--cread (also cupdate and cwrite) ignores it and does + not allocate another Mntcache for it. This is a fine way of + preventing Mntcache entries from being stolen repeatedly due to + reads and writes; that only happens during open. + cache.c:310,321 + The list of Entents for the entry is searched for an entry + containing offset (the first byte read). If there is no such + entry, there is nothing of interest cached for the file. + Extents are sorted accordingly with their addresses + ([start/start+len]). + cache.c:323,361 + Starting to use the cache. cread copies bytes from the Extent + located previously (and following ones if necessary) to the + read buffer. total keeps the total number of bytes serviced, + and len maintains the number of bytes yet to be read. + cache.c:324,331 + Each extent uses at most on page to cache file contents. By + using extents instead of pages in Mntcache, the author can keep + track of byte ranges cached for the file. cpage returns the + Page structure for the extent; should it be nil, the extent + does not have memory caching anything and it is removed from + the list (:327) and released. If an extent did loose its page, + the author assumes that any following one (which could contain + cached bytes) has lost its page too. cpage (cache.c:156,164) + just calls lookpage, which is discussed in the memory + management chapter, to lookup the page used as a cache. + The author uses just pages to do caching. Other systems use + several kinds of caches, which in the end, are using pages too. + By using always pages to do caching, actual caching has to be + implemented just once: by caching pages. In the next chapter + you will see how Images (used to keep a memory image of used + files) are using pages too, as segments do. Simple, isn't it? + If you don't agree, try to think how caching could work if the + author did cache ``files'' or ``blocks'' instead of pages + coming from files--you should exercise open/close/read/write + requests on this imaginary cache hierarchy. + cache.c:333,336 + The extent has a page caching some bytes. o is set as the + offset within the extent corresponding to the offset in the + file. l determines how many bytes can be read from the Extent. + cache.c:338,344 + kmap ensures that the cached page can be read from the kernel + (you know it's a nop here), and the author ensures that the + page is released and kunmapped (nop) on errors. cpage returns a + page, and it should not be unmapped while the routine is using + it; putpage lets the memory system know that the page is no + longer in use by the caller of cpage. See lines :348,351 too. + cache.c:346 + Here is the read from the cache! memory copied from the extent + to the read buffer. + cache.c:353,361 + After memory has been copied from the extent, if the read + request needs more bytes, go to the next extent which has the + following bytes. Note the check: there could be no next extent, + or it could be that the next extent is not caching the bytes + right after the current one (it does not start at offset, but + starts later). In this case there is nothing more cached for + this read. + When some of the following bytes are missing from the cache, + the author refuses to check if any posterior extent would have + bytes within the range read. The benefit may not be worth the + effort. Besides, the caller of cread assumes that it reads a + contiguous initial portion of the region being read; the + trailing portion is read by the mount driver. Any change here + to bypass holes in the cache would require changes in the mount + driver too. The author assumption is used to keep the code + simple, yet provides effective caching (You should take into + account that most applications read entire file contents). + + Updating the cache + + sysread + mntread + cupdate() Updates cache contents. + + cache.c:460,478 + cupdate is called by the mount driver after reading the + trailing portion of the file region being read--that portion + was missing from the cache and cupdate adds it to the cache. + Any further cread would now find that portion too. Initial + checks are like those in cread, for the same reasons. + cache.c:483,489 + The Extent list for the Mntcache entry is to be kept sorted by + file offsets cached. + cache.c:491,499 + f is the extent starting past the offset added to the cache (if + any), and eblock the end of the new portion cached. So, if the + portion read overlaps with the next extent, only bytes missing + up to the start of that extent must be inserted (remember that + the author stops at the first hole while reading). If all the + portion being updated in the cache overlaps with the next + extent, just forget about the update. This could happen because + several processes could read from the channel, find the hole in + the cache, issue Treads for the file, and try to update the + cache. Only one copy should be added. + cache.c:501,509 + These lines are the special case for insertion when it has to + be done at the head of the extent list. cchain does the actual + work of allocating extents and memory to cache the bytes + updated. It returns a pair of pointers to the first (returned + value) and last (in tail) nodes linked as a (sub)list to be + inserted. When inserting at the head, the next of the last new + node is the first node of the list (f, although using m->list + would be more clear); and the new head node is the first of the + list allocated. cchain is discussed later. + cache.c:511,522 + Not the first node, so cupdate ensures that this does not + overlap with any previous node (as it was done before with any + posterior node). + cache.c:524,540 + ee was set as the end of the previous extent (:512). If offset + is precisely that, the updated portion is contiguous to the + previous extent. If the previous extent length is less than the + page size, it could accommodate up to BY2PG - p->len bytes for + the updated portion. Do so. It could be the case that it could + accommodate all the updated portion, in which case there is no + need to allocate more extents (cchain would be never called). + cpgmove is just a memmove that gets and kmaps the extent page + while copying memory (:435,457). + cache.c:524,547 + As it was done with the head, cchain allocates more extents to + accommodate bytes updated. This means that the previous node + was either not contiguous or not with enough space on its page + to cache all the updated bytes. How does cchain work? + + sysread... + cupdate + cchain() Creates a chain of extents to update the cache. + + cache.c:368,381 + You know its interface. It loops creating extents to keep more + bytes from buf until the number of bytes yet to be updated is + zero. It is not considered a serious problem if no new extent + can be allocated; in this case, nothing more is cached. When + all NEXTENT extents are in use, nothing more is cached. + cache.c:383,387 + An extent caches at most one page. auxpage returns a page that + can be used by the caller. Should no page be available, there + is no need to keep the the extent. + cache.c:388,409 + After noting in the extent what it would be caching, the bid + field of the extent is set to the pgno counter in cache. This + value is also noted in the daddr (disk address) field of the + Page used, and can be used both for consistency checks + (:160,161) and to lookup a page with a given bid. pgno is + incremented not by one, but by BY2PG instead; it is being used + as the address in a fictitious device where all pages used by + the cache are kept in allocation order. + cache.c:410,417 + The memory updated in the cache is copied into the extent page. + cache.c:419,420 + Before releasing the page, cachepage is used to add the page to + a page cache. That is discussed in the virtual memory chapter, + but note how extent pages are kept in the page cache. Extents + are just adapting the page cache to serve as an extent cache + for remote files. + + Writing to the cache + + syswrite + mntwrite + cwrite() Updates the contents of a cached file (new version). + + cache.c:551,574 + cwrite is called to write to cached files. It increments vers + both in the Mntcache and in the channel QID, as the file is + being updated. + The mount driver calls cwrite just for Twrites on cached files, + and that is the case when it increments the QID vers for the + file; if somebody else is using the file and the server is + incrementing its vers field, this client wouldn't notice. Other + file systems tried to enforce coherence to the limit, and as a + result, forced clients to be blocked while transactions for + other clients were ongoing. In Plan 9, if this relaxed + coherence model is a problem, the application should use OEXCL + to ensure that only one process at a time has the file open--or + rely on any other synchronization means. + cache.c:576,599 + The first extent for the portion written is located. If such + extent is not the first one or does not exist (:583), the + routine tries to use any final hole in the page for the + previous extent--if contiguous. This is the same of cupdate. + cache.c:601,621 + The portion written could overlap an extent which would be past + the one being written. This could happen if the file has been + read into the cache (updated) and another process writes the + file or the reader does a seek to rewrite the file. The new + bytes written are the valid ones, and any previous copy has to + be released. extentfree is used to release the extent, rather + than reusing it. In that way, cchain can be used to add more + extents to the cache as it was done in cupdate. + I think that cupdate and cwrite could be serviced by a single + routine, like happens typically with read and write. But the + author may disagree. + + I/O + + You now know how files work in Plan 9, but you still have to look at + how actual I/O is done. Prior to the 3rd edition, Streams [[240]13] + were used as the framework to do I/O (i.e. to read/write from + devices). In the 3rd edition, streams were replaced by a more simple + (and less flexible) queue based I/O module. In this chapter you saw + how pipes used qio facilities to do I/O, and in previous chapters you + saw how the console and serial lines used qio too. The kernel uses + queues for I/O wherever there is an I/O flow of bytes from a source to + a drain. This happens when using devices and also when using artifacts + like pipes. I suggest you revisit the pipe device after reading qio in + this section, so you could fit the pieces together. + +Creating a queue + + qio.c:25,50 + a queue is a flow of bytes from the source to the drain (e.g. + from the keyboard device to the reader of the console + keyboard). The queue maintains Blocks, each with a block of + bytes. Queues perform flow control activities; they block the + reader when the queue has nothing for the drain, as well as + they block the writer when there is no room in the queue. Let's + see all this while you learn how routines to use Queues work. + If you look at the file, the initial part is implementing + routines that operate on Blocks and the final part is + implementing queue routines. + + qopen() Opens (prepares) a queue for I/O. + + qio.c:740 + A queue starts its service when a call to qopen creates it + (devpipe.c:67 and :72). qopen receives the maximum number of + bytes to be kept buffered by the queue (limit). If you look the + comment, you will notice that qopen uses malloc and should not + be called from an interrupt handler, because malloc could try + to acquire locks to allocate memory and cause a deadlock with + the process being interrupted. + msg is true if the queue is queueing messages and not bytes. + This is an important parameter. For a pipe, it does not matter + whether the bytes fed to the pipe were fed in a single write or + in a couple of writes; if the reader reads N bytes, it should + get those N bytes if they are present in the + queue--independently of how were they written. However, for a + network transport and other devices, it is important to read + what was written, no more, no less. If a network device places + two network packets in a queue, and a network transport wants + to get the next packet received, it should be able to read just + the last ``message'' written (i.e. the last packet queued). + Other way to say this is that queue can either delimit data + from different writes or not. msg is a way to make Queue a + generic queueing tool. + The kick and arg parameters are used to let the queue user do + something before flow controlled processes are awaken. This is + a convenient thing to have to make more simple the code of the + queue users. devpipe has nothing special to do and passes nil + as kick. However, the ns16552 serial device passes ns16552kick + as its kick procedure (to restart serial output). + qio.c:744,759 + inilim is the initial value for limit; more soon. state holds + the state for the queue, which is initially Qstarve (no bytes + in) and Qmsg if the queue is message oriented. eof and noblock + are cleared and you will see what this means. + +Read + + qread() Reads bytes from a queue. + + qio.c:860,873 + qread is the procedure to read bytes from a queue. Read the + comment. It calls qbread, who does the actual job of reading + len bytes and returning a Block with the bytes. qbread returns + zero if there is nothing more to be read (the queue was closed + and nobody would write more bytes on it, and the queue is also + empty). BLEN()Returns the length of data in a block. + portdat.h:134 + BLEN is defined to take a pointer to a Block, and return the + difference between its wp and its rp. That is the number of + bytes yet to be read in the Block. + portdat.h:123,133 + It is clear what is happening here, a Block contains a series + of bytes at base (the first one is base[0], and the last one is + base[lim-1]). Bytes written into the block are written starting + at wp (which would be initially base). Bytes read from the + block are read from rp (which would be initially base, and + should never go beyond wp). + qio.c:873,877 + qread copies the bytes in the block (len bytes) to the user + buffer (vp), and then it releases the block. freeb is discussed + later. + + qbread() Reads a block from a queue. + + qio.c:773 + qbread does the actual work of reading from the queue. Besides + helping qread, it is a queue read routine on its own--it is + very useful to implement devbread procedures. + qio.c:778 + A queuing lock is gained on rlock, where queue readers + synchronize. qlock maintains a list of blocked processes so + that the first who called qbread would be the first getting + bytes from the queue, if it blocks while acquiring the lock. + qio.c:785,807 + On this loop, an ilock is done on the queue, this prevents any + interrupt handler from using the queue, because no interrupts + can arrive while holding the lock. Once the lock on q is + gained, no one is messing up with the queue block pointers and + they can be used safely. If the list of blocks in the queue + (bfirst) is not nil, b is the block to read from, so break the + loop. If there are no blocks (!b), and the queue state is + Qclosed there will never be a block, so the author releases the + locks, sets the eof flag in the queue and the routine returns + zero as the number of bytes read. A read count of zero is the + convention in Plan 9 for signalling EOF. When EOF is signalled + more than three times, the reader could be ignoring EOF and the + routine raises an error instead. q->err contains the error + string to raise; e.g. qclose sets it to Ehungup. + If the state is not Qclosed, and there is no block in the + queue, this process must wait until the source (the writer) + puts more bytes in the queue. So, the author sets the Qstarve + flag to let the writer know that a reader is starving (waiting + for bytes), the q lock is released (so that the writer could + add more bytes to the queue) and the process sleeps on rr until + notempty. notempty lets sleep know that it shouldn't sleep if + there are bytes to be read in the queue. The parameter for + notempty is the queue being read. When the process wakes up + later, it would repeat the loop, check for Qclosed again (the + writer could close the queue instead of writing to it) and that + process repeats until there is a block in q->bfirst. + BALLOC()Returns the number of bytes allocated to a block. + qio.c:809,814 + Got a block. The routine removes it from the head of the list + (Blocks are linked through their next field). dlen counts the + number of bytes in the queue, as a block of n bytes has been + removed. len counts the number of allocated bytes in the queue + (i.e. number of bytes from base to lim-1 in all blocks + linked)--BALLOC (portdat.h:135) is a macro counting the number + of allocated bytes in a block). + qio.c:818,837 + If the block has more bytes and the queue is not message + oriented, remaining bytes (unread) should be kept in the queue. + If the queue is message oriented, the reader should read the + first message; no matter how many bytes it wants. Any unread + portion of the first message is discarded. Line :819 checks + that there are more bytes in the block (n) than wanted (len); + the next line checks that the queue is not message oriented. + Note the iunlock (lock held since :787). The lock is released + while allocating a block for n-len bytes, and copying those + bytes into the block allocated (wp is advanced to point past + the bytes written in the block). The ilock is done to mess up + with block pointers again while inserted the new block in the + queue--holding the unread portion of the previous block. By + releasing the lock, the queue can be used by others in the mean + time. + Line :836 sets wp in the block being read to point after the + bytes to be read from the block. Should the application write + to the block, it would not overwrite the data already placed in + the block. + qio.c:839,846 + The writer could be sleeping because there was no free room in + the queue to write more bytes. That is signaled by Qflow in + state. Should that be the case, if the used space in the queue + is below half its maximum number of bytes, the writer can be + awaken. Even though the queue may have (less than limit/2) free + room, the writer is kept sleeping. That is to avoid sequences + of sleep/wakeup/sleep/wakeup/...because the writer is awakened + too soon, fills up the empty room, and has to sleep again. The + queue state is changed before releasing the lock. After the + lock is released, other processes can lock the queue and + interrupts can arrive (if they were enabled before the ilock). + qio.c:848,853 + With the lock released, any writer sleeping awakened. If a kick + procedure is supplied to qopen, it is called. Usually, a + process waiting to write the queue corresponds to a process + doing output to the queue (possibly drained by a device). On + the other hand, when it is a device the one doing output to the + queue (an input device), the kick procedure can be used to + resume the device and allow it to put more of its data into the + queue--device input would happen at interrupt handlers and it + makes no sense to block (put to sleep) an innocent process just + because it happened that it was running while a device received + an interrupt stating that there are more bytes to add to an + input queue. + qio.c:856,857 + Until now, any other reader would be blocked on the rlock--one + reader at a time!. Now other readers are allowed to enter the + critical region and the block with the bytes being read is + returned to the caller. If the queue is message oriented, all + the bytes in the first block of the queue are returned; + otherwise, just the bytes wanted. + +Other read procedures + + qconsume() Reads from a queue even within interrupt handlers. + + qio.c:451,517 + Within an interrupt handler, qread cannot be used. qconsume is + like a qread which can be used by interrupt handlers (e.g. + devns16552.c:475). First, qconsume does not call qlock, which + may call sleep and perform context switches. (Is there any + context to switch while you are running within an interrupt + handler?) Second, qconsume does not call sleep to block when + there are no bytes to be read--qconsume would return -1 + instead. Both routines, qread and qconsume, can be used on + system-call (and trap) handling kernel code, within the context + of a process. + As you see, routines for use on interrupt handlers (and those + that must synchronize with them) use ilock. If the kernel is + servicing a regular system call and a queue routine uses ilock, + no interrupts are allowed, and no interrupt handler can even + try to use a queue routine: no deadlock. If the kernel is + servicing an interrupt and the queue calls ilock, no interrupts + would arrive and there can be no context switch, so there can + be no deadlock. That is why the author avoids carefully any + call to sleep and context switches here. + Of course, other processors can still try to use the queue, but + would notice the lock, and would not interfere (they would + either block the process or spin to wait a bit). + qconsume takes care of being as lightweight as possible. Unlike + qbread, which would split the initial block into two ones when + only part of the block is read, qconsume uses the rp block + pointer to read only part of the block when len dictates that. + In that way, qconsume avoids block allocation. Along with this + line, any initial empty block is skipped and linked into the + tofree list passed later to freeblist. + + qget() Gets a block from a queue. + + qio.c:369,403 + There is yet another read procedure for queues, qget. It is the + most simple read procedure, and it is specialized just to get + the first block in the queue, if any. It never blocks, and is + appropriate for use on interrupt handlers too. qconsume can + read any number of bytes, but qget can only get a block. qget + is used mainly by the code in ../ip. The tcp/ip protocol stack + uses blocks to store protocol data units (e.g. network + packets). qget and other queue routines operating on queue + blocks, allow the tcp/ip code to use queues to do packet (i.e. + block) i/o. + + qdiscard() Discards bytes from a queue. + + qio.c:408,445 + qdiscard is not a ``read'' routine, but removes bytes from the + queue. It iterates through the queue blocks until len bytes are + discarded. If a whole block is discarded it is freeb'ed, + otherwise the rp pointer is used to ``read'' the bytes + discarded. There is no synchronization regarding qread, and the + routine does not block. It is also appropriate for interrupt + handlers. This routine is useful for ../ip code, which discards + data when it is known to be received by the peer node (e.g. + when data is acknowledged). + + qcanread() Is there anything to be read from the queue? + + qio.c:1160,1164 + qcanread is a small procedure, albeit an important one. Some + queue users would not like to read the queue when that would + block them (e.g. devcons). qcanread returns non-zero when there + is something to read. The caller can later call qread. There is + no guarantee (specially on multiprocessors) that the queue + would be still non-empty when qread is later called. The caller + of qcanread must ensure that by any other means if that is + important. + +Write + + qwrite() Writes bytes on a queue. + + qio.c:961 + qwrite is called to write bytes in the queue (e.g. + devpipe.c:327). If it is message oriented, the bytes written + are considered to be the message. + qio.c:970,989 + The routine writes at most Maxatomic bytes (32K) at a time in + the queue. It is reasonable to limit how many bytes can be + placed in the queue at a single qbwrite to avoid a writer + flooding the queue with a request so big that locks are going + to be held while acquiring resources to queue an unreasonable + amount of bytes (e.g. lots of pages in memory, etc.) It is also + good to keep this limit to put a reasonable limit on message + lengths, so that readers of message oriented queues do not have + to cope with unreasonable long messages. Important lines are + :976, which allocates a block for the n bytes being added at + this pass; :982,984, which copy the bytes from the user buffer + into the block using the wp pointer; and :986 which calls + qbwrite to do the job of queuing another chunk of (at most + Maxatomic) bytes. The while condition checks for Qmsg; if the + queue is message oriented, and a message is at most Maxatomic + bytes, the routine would not qbwrite any byte that does not fit + into a message. + + qbwrite() writes a block in a queue. + + qio.c:891,901 + qbwrite adds the block to the queue (e.g. devpipe.c:354). The + lock used is wlock. The queue can be read and written at the + same time, but writers serialize their access to the queue (in + the same way readers do). Like qbread, this routine is useful + to implement devbwrite procedures. + qio.c:904,927 + While adding the block, a lock on q is held. Again, an ilock is + used (know why?). If the queue is closed, there is no point on + writing on it, so the block is released and the queue error + returned. The loop keeps the writer there until the block can + be added; but if the length of the queue is beyond its limit, + no more bytes should be added. + If noblock is set (it was set initially to false by qopen), a + write on a ``full'' queue is discarded and qbwrite pretends + that n bytes in the block were written. If noblock is not set, + the writer of a full queue sleeps until the queue is below its + limit--and Qflow is flagged so that a reader would wake up the + sleeping writer. + qio.c:929,936 + The block is added to the queue and the queue len and dlen + fields are updated. Blocks are added at blast--they are read + from bfirst. + qio.c:939,942 + If a reader is sleeping waiting for bytes in the queue, the + routine wakes it up. If there are multiple readers, the first + one holds rlock while sleeping, so other readers would not even + enter to read the queue until the first one is awakened and + gets the bytes. That is the reason for having just one bit to + signal ``readers waiting'' ``writers waiting''. + +Other write procedures + + qiwrite() Writes to a queue (for console). + + qio.c:999,1045 + qiwrite is a version of qwrite folded with qbwrite. It exists + because console routines may want to write on queues during + boot time, even before there are real processes (see + devcons.c). ilock is used (to prevent further interrupts too), + but there is no qlock (read the comment). That means that only + the lock on the queue is gained, but in no case the ``current + process'' (which could be simply the flow of control existing + at boot time) would call the scheduler within qlock. Besides, + flow control is not obeyed, the caller will never block because + the queue has gone beyond its limit. + In any case, it works like qbwrite, and would wakeup any reader + waiting. + + qproduce() Writes bytes on a queue even within interrupt handlers. + + qio.c:634,683 + There is yet another routine that writes to the queue, it is + qproduce. Like qiwrite, it does not use qlock. It does not + enforce Maxatomic, and never sleeps. qproduce is to qwrite what + qconsume is to qread. qproduce is intended to be called by + interrupt handlers (E.g. devns16552.c:725). When the queue goes + out of limits the block is not added and an error signalled by + returning -1. Besides, iallocb is used to allocate a block, and + not allocb. The iallocb version of allocb knows it runs within + interrupt handlers. + + qpass() Writes a (list of) block to a queue. + + qio.c:519,564 + qpass is the counterpart of qget. It writes a block in a queue. + There is no lock on q->wlock, and there is no call to sleep for + a full queue. The routine is also appropriate for interrupt + handlers. One interesting thing is that the routine adds not + just one block, but a list of blocks (:534,537) and accounts + for that (:541,546). Another interesting thing is that it + enables Qflow not when len goes above limit, but when it goes + above limit/2 (:551). + Queues get full when the limit is passed. Usually, it is a + write which makes the queue go above limit the one that sets + Qflow. In this case, the routine is used to write whole blocks + (maybe more than one), so the author takes care not go too far + above limit, and half the limit is used as a limit. + This routine is very useful for the code in ../ip , to place + protocol packets (queue blocks) into queues to be serviced + later. + + qpassnolim() Writes a (list of) block to a queue without obeying + limits. + + qio.c:566,606 + qpassnolim is exactly as qpass, but does not check for limit. + In this case the author wants the list of blocks to be written, + no matter the queue fill state. I don't know why the author did + not add a flag to qpass, to avoid checking the limit, and wrote + instead qpassnolim. Perhaps nobody cared to do code cleanup in + qio.c, or perhaps careful measuring suggested the multiplicity + of routines. By the way, qpassnolim seems to be used for the + ../ip code when the author knows it is okay to overflow the + queue to pass data to another part of the protocol stack. + + qwindow() Is there room in the queue for writing? + + qio.c:1146,1155 + qwindow is to be used like qcanread, a caller of qwrite can use + qwindow to see if the qwrite would block or not. + +Terminating queues + + qhangup() Hangs up on a queue. + + qio.c:1095,1109 + qhangup is used to state that no one else will write anything + more to the queue. However, the queue is kept with any block + not yet read. The err field is used to report that the queue is + hunged up (or the message supplied by the caller), and state is + set to Qclosed. Any reader would notice the Qclosed and it will + not block waiting for more bytes. Any writer will just discard + the bytes being written. notempty (:766) returns true when the + queue is closed, so that sleep will consider that there is no + need to sleep on a closed queue. The two wakeups would wake up + any reader or writer sleeping, and they will behave as I just + said. Did you noticed the ilock? + + qclose() Closes a queue. + + qio.c:1062,1088 + qclose closes the queue--like qhangup. Unlike qhangup, it + releases any block in the queue (:1083). qhangup is intended to + be used when one end of the queue hangs up, and how qclose is + more like a ``free'' routine (e.g. devpipe.c:228,229). Another + way to see it is that qhangup can be used by writers to signal + that there is nothing more to come; while qclose can be used to + shutdown the queue. Qflow and Qstarve are cleared. Perhaps they + should be cleared by qhangup too. + + qreopen() Reuses a closed queue. + + qio.c:1123,1132 + qreopen can be used to undo the effect of a close. It clears + the Qclose and sets the Qstarve and eof fields as in qopen. The + purpose is to reuse closed queues instead of allocating new + ones (e.g. devpipe.c:247,248). + + qfree() Deallocates a queue. + + qio.c:1051,1056 + When the queue is no longer needed, qfree does the close and + then calls free. It can be called for an already qfree'd queue, + as free checks for nil pointers and qclose does so too. The + comment suggests that perhaps qclose should add reference + counting and free the queue when the reference goes down to + zero. + +Other queue procedures + + qcopy() Copies bytes from a queue. + + qio.c:688,734 + qcopy is used to copy bytes from the queue into a new block. + Bytes are not read from the start of the queue. Instead, qcopy + copies bytes from the given offset in the queue. Lines :701,715 + locate the block and ``rp'' (p) where to start reading, and + later lines perform the copy. The queue blocks and their rp are + kept untouched. This routine is used by the ../ip code, which + usually likes to copy data out of network messages. + +Block handling + + Routines early in qio.c perform operations on blocks. They are mostly + of interest to protocol stacks using queues as their I/O mechanism. + For instance, code adding headers, extracting data, etc. from network + messages use these routines. I think you should be able to understand + these routines: + + qio.c:91,133 + padblock takes a block and returns a new block (or the same bp + if it has enough space) with size extra bytes of padding at the + front or at the back. That can be used to add headers or + trailers. + qio.c:138,150 + blocklen uses BLEN to return the length of a list of blocks. + Some times, specially when a message is traveling through a + protocol stack, a message may end up being a sequence of + blocks. + qio.c:155,174 + concatblock takes care of merging all the linked blocks into a + single one. Some routines assume that a message is contained + within a single block, concatblock can be used to ensure that. + qio.c:179,232 + pullupblock checks that there are n bytes after the bytes in + the block (after rp). It allocates a new block if needed. This + is useful to add n bytes to a message without turning the + message into a block list. + qio.c:237,273 + trimblock trims a block to a subset of the bytes on it. Useful + to remove unwanted headers and trailers. This can be used to + trim bytes at the front, at the end, or at both sides. + qio.c:278,302 + copyblock copies bytes to a new block. + qio.c:304,330 + adjustblock truncates the block to len bytes. Perhaps, + trimblock could be used instead of providing a new routine, + although this routine would run faster. + qio.c:334,364 + pullblock removes bytes from the front of a block list. + + Finally, note how most queue routines update statistics declared at + qio.c:109,14. Those counters tell the author how intensively are used + the routines involved. For instance, if qcopycnt goes too far, it may + be a symptom that queue copies should be avoided if there is a + performance problem involved. Statistics are important in that they + let the author know the real usage of the code; most of the author + assumptions would not correspond to the real system usage as seen by + the statistics. + +Block allocation + + allocb.c:24,56 + allocb is the routine allocating blocks always but for + interrupt handlers. The memory allocated is for the Block + itself, and also for the data to be kept in the block. Hdrspc + empty bytes are kept allocated besides the n bytes requested + (the total allocated space is size+Hdrspc+sizeof(Block)). That + is to allow protocol stacks to place their headers before the + data in the block. Should the author not do so, almost every + step in a protocol stack would require allocating new blocks, + concatenating them, and releasing previous blocks. The system + I/O for networks would go unbearablely slow. Another + interesting thing is that the routine raises an error (unlike + iallocb). + base is set pointing past the Block in the allocated memory, + and rp and wp are set pointing after the Hdrspc (which is + computed by subtracting size from the limit of the allocated + memory). + The dance around BLOCKALIGN is ensuring that pointers are + aligned to BLOCKALIGN (8) bytes. That can prevent alignment + errors on machines that are picky regarding where can integer + values be placed in memory. Not the case, but this does not + hurt. + The memory held by the block would be released when free is + called in the block--the free block routine is appropriately + set to nil. + allocb.c:61,108 + iallocb is a version of allocb for interrupt handlers. The + difference with respect to allocb is that ialloc does not raise + any error (returns nil instead) and sets the BINTR flag in the + block (some ialloc accounting too, admittedly). The flag is + only used by freeb to do accounting, but is not used for other + things. + allocb.c:110,140 + freeb calls the free procedure, does accounting for iallocated + blocks, and releases the block. If a free procedure is + provided, free is not called on the block; providers of block + storage are responsible to reclaim unused storage. All the + pointers are set to Bdead, which is a meaningless value that + can be recognized quickly when the debugger prints pointer + values. + + Protection + + In Plan 9, there are several system calls (see auth(2) and fauth(2)) + that have to do with protection. However, before looking at their + code, it is better to understand the overall architecture of Plan 9 + regarding security. Read also auth(6) and cons(3). What I comment here + is just what I think you need to know to understand the code. + +Your local kernel + + Each Plan 9 machine is either a terminal, a CPU server, or a file + server. Each machine run its own Plan 9 kernel, customized to perform + well for the given task. Terminals are machines used to interface the + Plan 9 network to its users. For example, each user runs rio(1) (the + window system) at its terminal. Terminal machines use services from + other nodes in the network. In particular, a terminal uses a CPU + server to execute commands on it, and a file server to get files from + it. Besides, machines where you run your programs in the network (e.g. + cpu servers) use files serviced from your terminal (e.g. your mouse). + + Everything is a file in Plan 9, and file permissions are what the + system uses to provide protection. Each file has rwx bits for its + owner, its group, and others (you already know how that works, since + you did learn that for UNIX). Thus, one barrier of protection is + placed at the file server that services the files accessed. + + In Plan 9 there is no `superuser' as in UNIX. In UNIX, a user with + uid 0 is granted special privileges by the system, which has + conditionals in the kernel to allow such uid to do almost anything. In + Plan 9, no user is granted permission to do everything. + + Each Plan 9 kernel is booted by a a user, and that kernel only trusts + that user. The user who boots a node is referred to as ``eve'', as you + know. Each kernel services some files, and eve is granted special + permissions on those files--noticed the checks for ``eve'' while + reading the code? + + By trusting only the user who did boot the node, Plan 9 does not allow + other users (nor other kernels) in the network to do things to your + local files. Why does Plan 9 give special permissions to eve? + + If you have physical access to the system and can boot it, nobody can + prevent you from using another system (e.g. msdos) and access the disk + files without Plan 9 even knowing. Therefore, there is no security + breach in allowing you to bypass permissions for local files. + + To check permissions for a process accessing a file, each process has + a user identifier (Proc.user). The initial process belongs to the user + eve, who booted the machine. That user, types its user name and its + password and the boot process uses that information to authenticate + the user. Before this point, the boot process belongs to the user + ``none''. Say that the typed user name was nemo; once authenticated, + the boot process continues and processes forked would run on nemo's + name too. To authenticate, the user process uses auth(2) services to + get in touch with the authentication server (another machine) and gain + tickets for the user. While authenticating, authwrite (auth.c:422) is + called to respond to a challenge, and if the reply is ok, the user + field of the process is changed according to the user who is + authenticating. So, each machine trusts the authentication server and + itself; it usually trust nobody else. + + For terminals, this is mostly what happens. For CPU servers, the user + who boots the CPU server has some processes on its name, and must be + able to create processes for other users willing to compute on the CPU + server considered. What happens, is that the user owning the CPU + server is granted permission (by the authentication server) to speak + on behalf of the user that wants to compute on the CPU server. + +Remote files + + According to what I said, other nodes will not trust you. How could + they trust you? Actually, the Plan 9 kernel does not care--mostly. As + far as the kernel is concerned, your files come from a server (a set + of servers actually) speaking 9P through a set of mounted file + descriptors. It is you who get those file descriptors by setting up + network connections to file servers. If you can authenticate to a file + server in the network, and convince it to speak 9P for you, you can + later give the descriptor to mount(2) and bring the server files to + your name space. In principle, your local kernel does nothing to let + you authenticate to the remote server and get your 9P session up. What + your local kernel does is to check protections for your local files. + + As an example, you must first authenticate to a Plan 9 file server to + use its files. (e.g. you authenticate with a file server kernel to + access your files; you authenticate with your local kernel to get + access to files serviced by the local kernel; etc). This can be + considered to be a first barrier of protection: convincing the file + server to speak 9P with you. Later, the file server will be checking + permissions, given the attributes of its files and your + (authenticated) identity; you can consider this as a second barrier of + protection. + + By placing authentication mechanisms outside the system (which only + has to handle 9P), and letting you obtain the authenticated + connections to file servers, Plan 9 can be as secure (and as insecure) + as you want it to be. + + One thing the kernel does for you is to keep your tickets--after you + gave your user name and password while booting--to authenticate + connections for which you already have tickets. Of course, you can + still use any other means to protect connections with your file + servers, and then mount the connection descriptors. + + The code keeping your user id and your ticket (generated from your + password) is found at /sys/src/9/port/auth.c, with console files + serviced by /sys/src/9/port/devcons.c. I think you should be able to + read that and understand it, provided you understood auth(6) and + auth(2). + + Memory Management + + Plan 9 uses paged virtual memory. Although on Intels there is + segmentation hardware, hardware segments are used just to implement + protection ring 0 for the kernel and ring 3 for the user--go back to + the introduction chapter if you forgot. Hardware segments are not to + be confused with process segments, which is an abstraction implemented + in software by Plan 9. + + Before discussing memory management system calls like segbrk, + segattach, segdettach, segfree and segflush, I start by discussing how + memory management works. You already know a bit about this, from + chapter [241]3. I hope that way you will learn what data structures + are involved, and you will understand better the code related to + memory management system calls and memory management trap handlers. + + During this chapter, you will be reading these files: + * Files at /sys/src/9/port + + fault.c + Page fault handling. + + page.c + Paging code. + + segment.c + Process segments. + + swap.c + Swapping code. + + sysproc.c + Process system calls. + + devproc.c + Process device. + + devcons.c + Console device. + + * Files at /sys/src/9/pc + + mem.h + Memory management definitions. + + memory.c + Actually discussed at chapter ch:start, but you may want + to reread it here. + + mmu.c + Memory Management Unit handling code. + + trap.c + Entry points for MMU faults. + + dat.h + Machine dependent data structures. + + Processes and segments + + ../pc/mem.h:29,54 + To remind you, the kernel uses the paging hardware (two-level + page tables) to implement virtual memory. Each process has its + own virtual address space, split into two regions, one for the + kernel and another for the user. The user portion of the + virtual address space is using addresses from 0 to 2G + (0x00000000 to 0x7fffffff). The kernel portion goes from 2G up + to 4G (0x80000000 to 0xffffffff). The last two Gbytes, for + kernel usage, are shared among all Plan 9 processes, which + means that their entries in the hardware page tables are the + same[242]10.1. You should remember among other things the + identity mapping for physical memory. + From the point of view of the process, things are different + (see figure [243]6.1). Its 2G of the virtual address space + (what it can see) are structured into segments. A process knows + it has a set of segments attached at concrete virtual addresses + with concrete lengths. For instance, all processes have a text + segment (with instructions) at address UTZERO, past the first + page--which is kept unmapped to catch dereferences for nil + pointers. Besides, processes have stack, data, and BSS + segments. + + CAPTION: Figure 6.1: The user view of a virtual address space: A text + segment with the program code, a data segment with initialized data, a + BSS segment with uninitialized data, and a stack segment. + + mem.h:60,77 + Do not confuse the process (software) segments with the + hardware segments used by Plan 9. + +New segments + + Let's start by looking at how are new segments created, considering + first a stack segment. + ../port/sysproc.c:324,329 + The boot process was given segments by hand by the kernel + bootstrap code and the first thing it did was an exec system + call to execute the code for the boot process. sysexec then + calls newseg to create a stack segment for the new program. To + remind you, segments for a Proc are kept linked to its seg + array, which has NSEG entries. If you remember from the chapter + on processes, ESEG is an slot for an extra segment (SSEG is the + slot for the stack segment). + + newseg() Creates a segment. + + segment.c:47,54 + This procedure creates a segment of a given type, base and + length. It aborts if the size is beyond the maximum size + allowed for a segment--size is in pages, as segments must + contain an integral number of virtual memory pages because the + paging hardware is used to implement them. + portdat.h:365,383 + If you look at Segment, you can see how there is a map + array with pointers to Pte structure (see + figure [244]6.2). + + CAPTION: Figure 6.2: A Segment maintains a virtual MMU data structure + holding Page structures for pages in the segment. + + portdat.h:323,329 + A Pte contains at most PTEPERTAB pointers to Page + structures, each one responsible of a (virtual) memory + page. + What is happening is that a segment is using a virtual MMU + as its data structure. So, the map in Segment is like a + two-level page table that lets the segment hold pointers + to all Page structures for the pages it has. The reason + for using this two-level structure is the same reason the + hardware has for using two-level page tables: to save + memory yet to be efficient when looking up entries. + ../pc/mem.h:104 + As map will have at most SEGMAPSIZE entries, and each + entry has (../port/portdat.h:325) at most PTEPERTAB + pointers to pages, the maximum number of pages is the + limit checked at segment.c:53. + swapfull()Running out of swap space? + segment.c:56,57 + To implement virtual memory, all pages that do not fit into + main memory are kept in a swap file (which could be a swap + partition, since partitions are files). swapfull + (swap.c:406,409) returns true when the swap file has less than + a one tenth of free space. The kernel refuses to create new + segments when it thinks that there will be no space in swap for + backing up the segment. + segment.c:59,64 + The new Segment is created. It is reference counted because + processes can share segments. The type, base address, and top + address (the first address past the last address in the + segment) are kept in the Segment structure. + segment.c:66 + mapsize is set to the number of map entries (PTEPERTAB entries + each) needed to hold size pages. Part of a the last Pte in map + could be unused. + segment.c:67,73 + nelem is a macro returning the number of entries in an array + (portfns.h:173). If more entries are needed than the number of + entries in the (small) ssegmap array kept in Segment, map is + allocated to contain twice the entries needed--unless that + value goes over the maximum number of entries, in which case, + just the maximum is allocated. + The author is allocating twice the space required because he + thinks that in the future the segment could grow. In that case, + the author wants to be sure that allocated space would suffice + most of the times. That makes unnecessary to reallocate + existing entries. Right now, all pointers in the map are nil, + because smalloc is used. mapsize holds the number in entries in + the map array. + segment.c:74,77 + What happens when there are less entries in map than entries in + ssegmap? map is set pointing to ssegmap, instead of allocating + a fresh new map. The author made a provision for small + segments, so that they do not incur in the overhead of + allocating/deallocating maps. Small segments are serviced just + with the Segment structure. This is also a help to fight + fragmentation, not just execution time, because less structures + have to be allocated. + segment.c:79 + Finally, a new Segment structure with enough entries in map + (all nil) is returned. + +New text segments + + sysexec + + sysproc.c:381 + During sysexec, a new text segment for the code found in the tc + channel is created. + + sysexec + attachimage() Creates a segment attached to a file image. + + segment.c:246 + attachimage tries to create a new segment of the given type. + Unlike newseg, attachimage attaches a file image to the + segment, so that the segment would appear to contain whatever + is contained in the file referenced by the channel c (see + figure [245]6.3). + + CAPTION: Figure 6.3: A Segment can be attached to a file image. + + segment.c:251,252 + imagechanreclaim is discussed later--it is just closing unused + channels which were used to fill up other images. + segment.c:254 + Locking the imagealloc, which is an allocator of Image + structures. + segment.c:19,31 + The imagealloc contains a free list of Images, and a hash table + for Images. You will be seeing how it is used. + portdat.h:309,321 + An Image represents the image in memory for a portion of a + given file. As attachimage takes a channel to a file and builds + a segment upon its contents, Images are very important here. + Just note how an Image contains a channel to the file used as + the source of data for the image (c), and how there is a link + to the Segment which is using the image of the text file. + segment.c:260,261 + All Images under imagealloc are kept hashed on the QID of they + file they come from. ihash selects the appropriate hash entry + in imagealloc. Each hash bucket has images linked through the + hash field of Image. The author is searching for an Image which + comes from the same file; therefore, the qid.path of the + channel is compared to the qid.path of the Image (Images keep + the qid for the file they are maintaining). + segment.c:262,270 + Should an Image for c's file be found, the image is locked and + the QIDs compared (with eqqid this time). The check at :261 was + a quick guess to avoid locking all images in the cache just to + find out that they are not the ones of interest. In the real + check, the QID, the QID for the channel to the mounted file + (which could be zero if not mounted), the channel to the + mounted server and the device type are compared. If you + remember, two files are the very same file if their QIDs match, + they are serviced by the same device type, and the actual + server is the same. This is the check being done here. Lines + :264,265 are needed to distinguish between different channels + going through the mount driver, but pointing to different files + on different servers. + If such an image is found, a reference is added and the routine + continues at :298, with the image locked. The author knows that + only a copy of the file text has to be kept in memory. If you + run different processes for the /bin/rc program, the text has + to be in memory just once (because it can be shared due to its + read-only nature). Therefore, all such text segments would be + sharing their Images, which would be just a single Image for a + channel going to /bin/rc. + segment.c:274,285 + No Image was found for the text, so the author allocates a new + one. The loop, which calls imagereclaim, tries to deallocate + Images back to the free list. The process doing an exec would + be looping calling imagereclaim, and letting other processes + run until it can get an Image from the free list. This process + could do not much else, because exec did commit to execute a + new process and it cannot be even aborted. The choice is either + wait for an image or die. The imagealloc lock is released while + allowing others to release images. + segment.c:287,299 + The new image is locked, a reference added to it, and its + fields initialized. The Image is linked into the hash bucket + corresponding to the file's qid. imagealloc is unlocked but the + image remains locked. + segment.c:301,312 + i could be a newly allocated one, or one reused (shared) from + the hash. If the Image comes from the hash, its s field points + to a text segment, which would be shared, so a new reference is + added to it. If the image is new, it has no segment yet, so + newseg allocates a new segment of the type desired, and its + image field is set pointing to the image. You can go from the + segment to the image using image, and back to the segment using + s. The waserror handling code does not call nexterror, because + the caller is gone during sysexec. Instead, the process is + killed on errors. + segment.c:314,315 + All set. Either a fresh new image created or a previous one + shared. + + sysexec + + sysproc.c:382,387 + attachimage returns the image locked. The caller adjusts the + fields fstart and flen in the Segment using the image to record + the portion of the Image which should be used to fill up + segment memory. In the case of the text segment, its bytes come + right from the beginning of the file--even the header is + ``mapped'' within the text segment (looks like the real text + file, doesn't it?) + sysproc.c:393,397 + In the case of the data segment, its bytes come from the text + file, past the code. + To summarize, an Image is an image of a program file kept on + memory, it is attached to one or more segments, and each + segment attaches to a portion (fstart, flen) of the file image. + We will get back to images later. + + Page faults or giving pages to segments + +Anonymous memory pages + + I use the term ``anonymous memory'' (as others do) to refer to memory + which does not come from a file. For example, text and data segments + have their contents coming from the file with the program being + executed. Stacks and BBS segments, on the other hand, are created with + cleared memory, which does not come from any file. Let's pick up the + stack segment as an example to see how it gets some pages. + + sysexec + + sysproc.c:329,333 + Once the process has a segment, it can reference addresses + within the segment. When are pages given to segments? When does + a segment get actual memory? If you read the comment, you'll + get a hint. + Segments are made of virtual memory pages. Those pages can be + either at physical memory, or at secondary storage. For the + stack segment just created at :329, there are no pages yet. But + the code below will write to stack addresses! + + trap + + ../pc/trap.c:218 + The first time the kernel writes to an address within the first + page of the stack (the last page in the segment due to stack + growing direction on intels), a page fault trap is generated. + That makes sense since the hardware MMU has the translation for + the stack page marked as absent. + trap.c:242,245 + The handler in the Vctl for the page fault trap is called--the + handler was set at :170 to be fault386. + + trap + fault386() Services a 386 page fault. + + trap.c:435,442 + fault386 receives the Ureg for the faulted processor context + (which would be code running within the kernel in the example). + Due to Intel nature, the faulting address is not saved by the + hardware in the Ureg, but is located in the cr2 register + instead. The routine saves the address in addr--another page + fault in the mean time would overwrite the cr2 and loose the + previous faulting address. + trap.c:443,445 + user is true if the saved context had the UESEL as the code + segment selector (i.e. it was code running at user-level). If + the page fault happened while running inside the kernel and + mmukmapsync can handle addr, nothing else is done--the page + fault should be fixed. mmukmapsync()Synchronizes kernel maps + for the MMU. + mmu.c:273,288 + We will see later, but mmukmapsync tries to get the hardware + page table entry (pte) for the faulting address. It uses the + pdb pointer for the boot processor, which points to the + ``prototype'' page table kept for processor 0. mmuwalk walks + through the page table to get the entry. If pte is nil, there + is no second-level page table and mmukmapsync does nothing. If + the entry in the second level page table is is nil, the same + happens. In our stack page fault example, there is no entry + added for the new stack page. Therefore, in our case, + mmukmapsync does nothing. + What is mmukmapsync doing then? Try to guess, later I'll tell + you. + trap.c:446 + If bit 2 is set in the trap error code pushed by the processor, + the fault was due to a write operation. So read means that it + was a read the operation faulting at addr. + trap.c:447,449 + insyscall records whether the faulting process was executing + within the kernel (e.g. sysexec) or was running user code. In + any case, you are now running within the kernel. fault is + called to do the actual processing... + + trap + fault386 + fault() Services a page fault. + + ../port/fault.c:9 + ...and it is given the faulting address and an indication of + whether it was a read the operation causing the fault or not. + fault.c:14,15 + The routine saves the previous process `ps' state (which would + be restored later) and lets `ps' know that the process is + faulting. As you can see, the author uses psstate to be more + descriptive regarding the process state; the process scheduling + state is a different thing. + fault.c:16 + Until now, interrupts were disabled--which also prevented + context switches to a different process. Now that the page + fault is being handled (and has saved cr2), interrupts can be + allowed. Servicing a page fault may take a long time. + fault.c:18 + Accounting for the local processor. + fault.c:19,38 + seg locates the segment where addr stands, if there is no such + segment, the address was outside segments used by the process, + and the fault cannot be repaired (hence the return -1). If the + fault was for write and the segment was a read only segment, + the fault cannot be repaired either. Otherwise, fixfault would + do its best to repair the fault--e.g. by allocating a new page + frame, filling it with the contents of the faulting page, and + repairing the address translation. As fixfault may fail due to + allocation failures, etc., fault loops until the fault is + either repaired, or is known not to be repairable. Finally, the + saved `ps' state is restored and fault returns 0 to indicate + that it repaired the fault (because fixfault returned zero and + the loop was broken). + ../pc/trap.c:450,459 + Before looking fixfault and seg, note that when fault returns, + if it returns zero, the insyscall state is restored, and + fault386 returns to trap, which would return (or context switch + to another process) causing a return from interrupt. The iret + restores the processor context and the faulting instruction is + retried. However, when fault returns -1, fault386 would either + cause a panic (if the faulting instruction was within the + kernel) or post a ``sys:trap:fault'' note to the faulting + process. That note can kill the faulting process. In our + current example, the fault will be repaired. + seg()Locates a segment given the address. + ../port/fault.c:359,380 + First, fault calls seg with the pointer to the current Proc, + the faulting address, and dolock set to true. seg iterates + through the seg array of up, looking for a segment in use (they + have a Seg hanging from seg[]) whose addresses contain addr + (note n->base and n->top). If such segment is found, a pointer + to the Segment is returned. + If dolock was true, the Segment is locked and the check is + repeated; to ensure that the segment was still there and its + addresses still contain the faulting address. + + trap... + fault + fixfault() Tries to fix a repairable page fault. + + fault.c:50,51 + Should a segment contain the faulting address (seg[ESEG] in our + case), fixfault is called for it. In this case, doputmmu is + true--because fault wants the address translation to be ok for + the hardware too. + fault.c:61,64 + va is the faulting address; addr is set to the page address (by + clearing the offset bits). soff is set to be the offset in s + for the faulting address. p is a pointer to the map entry for + the segment offset. + Segment maps contain entries relative to the base address of + the segment. The segment offset is used as an address to be + translated by the map--very much like the hardware does with + its page tables. PTEMAPMEM is the number of bytes addressed by + each map entry (../pc/mem.h:102,103 defines it as 1M, and + defines PTEPERTAB as the number of pages needed to cover that + Mbyte). + fault.c:65,66 + One thing which can happen (that's the case for us), is that + the segment does not even have a map entry allocated for the + faulting offset. ptealloc()Allocates a Pte. + page.c:466,475 + In this case, ptealloc allocates a Pte structure with PTEPERTAB + entries to link Pages on it. This is like allocating the second + level page table for the ``virtual MMU'' used to implement the + segment. All entries in the Pte are still nil. + fault.c:68 + etp is now a pointer to the Pte which should contain the Page + structure for the faulting address. + fault.c:69 + pg is set to point to the entry in pages where the Page for the + faulting address should be. The index is the offset within a + map for the segment offset, divided by the number of bytes in a + page. In our case, *pg is nil as nobody allocated a page for + the stack. + fault.c:70 + type contains the kind of segment handled. More later. + fault.c:72,75 + A Pte, contains first and last pointers that point to the first + and last used entries. They are used to iterate through all + used pages without having to iterate through all entries in the + Pte--which could contain just a few contiguous pages. These + lines update first and last accordingly. + fault.c:77,80 + How to repair the fault, depends on the kind of segment; note + the defensive programming once more. + fault.c:82,88 + For page faults within text segments, the page should be paged + in from the text file. pio does the job, as discussed later. + fault.c:90,105 + For BSS segments, shared segments, stack segments, and segments + mapped (from devices?), which is our case, the pg is checked. + If it is nil, there was no page for the segment and a new one + should be added. This is called ``demand loading'' or + ``zero-fill on demand'' depending on whether the new page + should be loaded from a file or should be just initialized to + all-zero; the ``on demand'' part means that the system does it + only when a page fault shows that the process demands the page + involved. + + trap... + fixfault + newpage() Allocates a new page (frame) for a segment. + + page.c:119,131 + newpage is called to add a page to the segment at the given + page address. More precisely, the segment had its page + ``officially'', but that page had no page frame; newpage + allocates a Page that represents a page frame and gives it to + the segment virtual memory page. + Clear was set to true to request the new page be cleared. By + now, consider that there are more free pages than the value of + swapalloc.highwater and the loop trying to allocate a page + breaks at :131. Forget most of newpage now, which is discussed + later, but note that by allocating a Page, the author allocates + a page frame too (the one at p->pa). + page.c:185,197 + The other thing of interest for us now is that a reference is + added to the Page (it is being added to a segment), its va is + set to the virtual address for the page, modref set to zero + (the cache of the hardware bits in the page table) and the + actual page frame for the page (at VA(kmap(p))) set to al + zeroes. The page frame is allocated for the page, and the page + is represented by the Page structure. More clear now? + + trap... + fixfault + newpage() Allocates a new page (frame) for a segment. + + fault.c:100,101 + Back to fixfault, after new is our new Page, it could be that + newpage did set s to zero because it had problems to allocate a + new page for the segment. In this case, the fault cannot be + repaired and the routine returns -1. Despite fixfault saying + that the fault is not yet repaired, fault retries + later-hopefully, a Page for the segment could be allocated in + the future. + fault.c:103 + The entry in the segment Pte for the page (pg) is set to point + to the new page. The segment has a new page which has a page + frame for it. The goto does not need to be there because the + case would fall through the next case. Probably in a previous + version there was a goto common at some other point in the + routine. + fault.c:107,108 + For our stack segment, a page is allocated on demand if no page + was there (the stack is growing), and the same happens for BSS + segments (which are all zero, so zero filled pages can be + allocated on demand). For a page fault on a data segment, + processing would start here. + pagedout()Is the page paged out? + fault.c:110,111 + pagedout (portdat.h:350) returns true if the segment actually + has the page, but the page is not really in memory because + either it was paged out (its page frame reclaimed for other + uses) or it was never paged in (never read from whatever file + it comes from). onswap (portdat.h:349) checks whether the + PG_ONSWAP bit is set in the pointer to the Page; which is the + convention for pages paged out. Thus, if the page was never + paged in, pagedout notices that the pointer is nil and says + that it was paged out (it lies). If the page was actually paged + out, its page exists, but the pointer has the PG_ONSWAP bit + set. In any case, the page has to be brought into a page frame, + before it could be used. pio does the job of paging in the + page. + In our current example, pagedout would return false. + fault.c:113,117 + If the access was for read, mmuphys is set to be the contents + of the page table entry (for the hardware MMU) for the faulting + page. PPN returns the page frame (physical page) number for the + entry, and bits for ``read-only'' and ``valid'' are set on it. + Besides, the software copy of the ``referenced'' bit is set. I + defer the discussion of copymode until later. Just note that if + the page fault was because the page was missing, it is now + in-memory, and the ``valid'' bit is set. The switch is broken + because that is all that has to be done to repair the + fault--but for updating the MMU page table entry. + fault.c:119,148 + The number of references for the page is computed. For us image + in the page is nil, so the number of references is just the ref + field in the Page. In our case, there is just one reference to + the page and code in :127,140 does not execute. As there is no + image for this page, only the unlock is done--no duppage + called. All this will become more clear for you later. But + let's concentrate on how are pages added to our stack segment. + fault.c:149,151 + The fault was for a write access, so fill up the entry + (mmuphys) for the hardware page table with the page frame + number and the write and valid bits. The ``modified'' and + ``referenced'' software bits are set in modref. putmmu()Updates + an MMU entry. + fault.c:173,176 + If the caller requested that the hardware MMU page table should + be updated, putmmu updates the entry for addr with the the + prototype in mmuphys. The Page structure is passed because on + some architectures putmmu might need to use/update Page + information, but that's not the case for the Intel. After + putmmu returns, the hardware page table has a valid address + translation from the faulting page to the just allocated page + frame. fixfault returns zero to state that the fault was + repaired, and fault would return to 386fault which would return + to trap. + At last, the faulting processor context would be reloaded and + resumed by the iret in l.s. In this case, the faulting + instruction was one in sysexec.c, filling up the stack for the + process; execution would continue from that point on. + The processing just described would also be the one when + addresses within the BSS segment are first referenced. The BSS + is a data segment initialized to all zeroes. By attaching pages + to it as they are used, and initializing their page frames to + all zeroes, the process can believe that the whole BSS segment + was there right from the beginning. The same happens for stack + segments, as you now know. + +Text and data memory pages + + trap... + fixfault + + fault.c:83,88 + If the process first references a page within the text segment, + these lines are reached. Processing is mostly like servicing a + page fault for the stack segment, but there are important + differences. Assuming that the page faulting was never brought + from the text file to the text segment, pagedout would find *pg + to be nil, and return true. pio is called to do page I/O on the + text segment. After it loads the program text that should go in + the page from the text file, mmuphys is updated with a + translation to the page frame for reading (that means + ``execute'' permission too). Later putmmu will install that + translation in the MMU page table. + + trap... + fixfault + pio() Performs I/O to do a ``page-in'' for a page. + + fault.c:180,191 + pio tries to get into *p a Page (with the associated page + frame) with its corresponding memory filled up according to + what is said in s. + fault.c:192,199 + If there is no Page pointer (which means that the Pte had a nil + pointer for this page), the page contents must be brought in + from the image attached to the segment. daddr is the address in + disk for page contents. The address is fstart (the address in + the image corresponding to the start of the segment) plus the + offset within the segment for the faulting page. (Remember that + there are different fstart values for text and data segments?). + lookpage takes the Image attached and the address on it, and + returns a cached Page for that image portion. Hopefully, the + Image would be caching that page most of the times, and no + access to disk would be required: new would be non-nil and pio + is done. Should new be nil, you have to go to disk to read page + contents. This is the if arm taken for the first reference to a + text (or data) page. + fault.c:200,208 + Should there be a pointer to a Page, that means that the page + was paged out. The pointer (as you will see) is not really a + pointer to a page, but a daddr with the PG_ONSWAP bit set. When + low on memory, Plan 9 reclaims page frames from user pages. If + a stack or a BSS page is reclaimed its page frame, page + contents must be stored somewhere else[246]10.2; i.e. on the + swap area. In this case, swapaddr returns the address in swap + where the page copy stands, and lookpage uses the swapimage + Image instead of the segment image. putswap marks the space + allocated for the page within the swap area as no longer used. + Swap space is allocated just to keep the pages moved out from + system memory. Unlike other systems (e.g. some UNIXes), Plan 9 + does not keep the swap space allocated when the page is kept in + memory. If the page ever needs to be paged out again, another + piece of swap space would be allocated for it at that point in + time. + fault.c:211,215 + The page was not found in the Image. It is definitely not in + memory. A new Page (with a fresh new page frame) is allocated. + The page frame is mapped at kaddr. + fault.c:217,252 + The page has been first referenced (see above). + fault.c:218,225 + About to read from the channel to the file where s->image + memory comes from. In case of error, release the page just + allocated and call faulterror--which would either pexit or post + a debug note. If page contents cannot be retrieved, there is no + much else to do. The routine cannot return by calling nexterror + because, in the end, the faulting context would be reloaded, + another page fault happen, another I/O error for the channel + happen, etc. + fault.c:227,231 + The read procedure for the channel is called to read into kaddr + (the page frame), ask bytes, starting at offset daddr (the + address for the page in the file). Lines :227,229 set ask to + the page size or the number of bytes from the faulting address + to the end of the segment--whatever is the minimum. The end of + a segment does not need to be aligned at page boundaries. For + example, a compiled file can have initialized variables (data + segment contents) which could occupy just 1K bytes, much less + than a page size; it would not make sense to read more than + that Kbyte from the file. + fault.c:234,235 + Remaining bytes in the page (3K in the example) would be set to + zero. After these lines, the page is loaded in memory. + fault.c:239,251 + While the page was being read into memory, the lock on s->lk + was released--reads take a long time. That means that some + other process could fault on the page too, and start to read it + too. The first process reaching line :239, would notice that + the Pte entry (*p) is still nil. So that process takes the + responsibility of attaching the page to the segment: its daddr + is set to the daddr computed, cachepage is called to let the + Image keep the page cached, and the Pte entry is set to point + to the page. The second process arriving here, would notice + that *p is not nil, which means that the work is done, so it + does nothing but to return (cachectl is not discussed here). + The call to putpage releases the reference to new, which could + cause the page to be deallocated when the number of references + becomes zero. + The author prefers to let one process do some unuseful work + some times (when faulting on a page being faulted by other + too), than to keep the whole segment locked (which would block + processes using that segment) just to avoid this (not so + probable) race condition. + One more note, pio does not fill up any MMU page table entry. + It just handles the virtual page table used by the segment, and + does Page I/O. The caller should call putmmu to let the + hardware know. + + trap... + fixfault + + fault.c:110,111 + For data pages first referenced, pio is called too, and + processing is like above. + fault.c:144,145 + However, for data segment pages first referenced (unlike stack + pages), duppage is called when there is enough space in the + swap area. What is happening is that data pages can be written. + If the data page is written, its contents would differ from the + disk file contents. + Now that the page is still fresh (it is just read), the author + prefers to employ a bit of time and memory to make a copy of + the page. The copy is to be kept by the Image, so that when + another process faults on this page, the initial contents do + not need to be read from disk, but from the Image page cache + instead. + +Physical segments + + fault.c:154,169 + If the segment is a bunch of physical memory, servicing the + page fault is done by allocating a Page structure for the + physical page already assigned to the segment. The way to + allocate the Page depends on whether the segment has a + pseg->pgalloc function or not. If it has one, it is the + provider of Pages, otherwise a Page is allocated and its pa is + set to point to the pseg->pa address of the segment plus the + offset for the faulting page in the segment. Physical segments + are discussed together with segattach. + +Hand made pages + + main + userinit + segpage() Adds a page to a segment eagerly; not on demand. + + segment.c:222,243 + segpage is used only during boot to add a page to a segment. + Page is supposed to be initialized by the caller, and segpage + only plugs the page in the appropriate Pte for the segment. + + Page allocation and paging + + You now know that segments are filled up with pages on demand. Let's + see now in more detail how are page frames allocated when segments + reclaim more memory. + +Allocation and caching + + auxpage() Allocates a page frame. + + page.c:240,246 + auxpage is called to allocate a Page structure, along with an + associated page frame. It is used by the code in cache.c to + allocate page frames for extents. Pages come from a free list + of pages in palloc. They are taken from head. + page.c:247,250 + freecount was initialized by pageinit to the number of free + page frames. For each page frame, a Page structure was + initialized (with its pa set to the page frame address) and + linked into palloc list (palloc.head/palloc.tail). + swapalloc.highwater was also initialized by pageinit to be + 5/100 of the number of page frames available for users (not for + kernel). So, if the number of free pages goes down a 5% of + available memory for users, auxpage refuses to allocate one of + the (now precious) free page (frames). + When the author uses auxpage, allocation could fail. An example + is cchain (cache.c:383), which does caching only if free pages + are available. So, what is happening is that the kernel cache + for remote files consumes only free pages, but refuses to grow + when memory is scarce. + Could the author use virtual pages to do caching? Yes, but in + that case they could go to disk, and reading from a disk can + (sometimes) be slower than reading from the network. Besides, + in any case, a local file server can be used to cache remote + files (e.g. cfs). + pageunchain()Removes a page from the palloc list. + page.c:251 + pageunchain (page.c:65,80) removes p from the palloc list and + adjusts freecount (one less page). The list is double linked + using the next and prev fields of Page--to remove any entry. + Saw how the routine checks that the palloc lock is held? + page.c:253,261 + The page should not be used (hence the ref check). A reference + is added to the page, uncachepage called, and the page returned + to the caller. The reason to call uncachepage is that the + caller is going to use this page for new stuff. Let's see what + this means. + + Images are used to represent an image in memory (read: cache) of file + contents. You should remember that lookpage is called with an Image + and a disk address to recover a cached Page for that offset within the + image. How can that be done? + + cachepage() Adds a page as a cache for part of an Image. + + page.c:365,385 + cachepage is called (as you know) when an image page is read + from its file. It locks the palloc.hash table, and adds the + page to the hash bucket for the page. pghash uses the daddr + (ignoring page offset) to hash the page. Since the page is + being kept for caching part of i, its image field is set to + point to the image and a new reference added to the image. The + whole picture is shown in figure [247]6.4. + + CAPTION: Figure 6.4: Palloc cooperates with Images, so that a cache of + pages is kept for Images. Pages are hashed on their daddrs and + maintained on a LRU list. + + lookpage() Lookup a page in the cache. + + page.c:411,439 + When later a routine wants a page from the image, lookpage + scans the hash bucket (given the disk address) for a page with + the same Image and the same daddr. If the page is found (note + the double check to avoid locking all the pages) a reference is + added to it (:428). + When an image is released by the last segment using it, its + pages are still kept in palloc.hash. If no one is using such + pages, their reference count would be zero. However, such pages + still contain file data which would save disk (or network) + reads. Besides being kept in the hash, free pages are linked + through the list starting at palloc.head. The call to + pageunchain removes the page from its list (the palloc.head + list). If this is the first new reference, the page must be + removed from the free list, but second and posterior new + references would find the page out of the free list (the page + might be reused multiple times if found by lookpage for + different segments). + + uncachepage() Removes a page from the cache. + + page.c:342,363 + Finally, pages leave the cache (are removed from the hash) when + uncachepage is called (e.g. after auxpage allocates an unused + page for a different purpose). At this point, the page is no + longer caching part of the file image in memory. + + To summarize, pages are initialized to represent fresh page frames + during boot. They are allocated later from the free list (initialized + at boot) and added to the hash for use as a cache. When their last + reference goes away, they are added again to the free list. Only when + they are used for a different purpose, they are removed from the + cache--in the hope that the same file will be used again (e.g. ls + would be executed once more). As long as there are free page frames, + nothing else happens. But what happens when physical memory is not + enough for segment pages and to cache file contents? + + newpage() Allocates a page. + + page.c:118,119 + newpage is called to allocate a new page for the given segment. + page.c:130,133 + For user processes, less than a 5% of free user pages is + considered as ``no more free pages''; kernel processes would + still get their pages until really out of memory. During this + loop, the caller process would be waiting to get a free page + for its usage. + page.c:135 + While waiting, release the palloc lock. This allows other + processes to use it (e.g. to release pages). + page.c:136,141 + If the caller supplied a pointer to its Segment*, which means + that it was allocating a page for that segment, the author + releases the segment lock, clears the Segment* used by the + caller and sets dontalloc. Later, after trying to get more free + pages, the routine would return (:154,161) without trying to + allocate a page. Can you guess why the author does this? + page.c:142,152 + In this critical region, the process calls kickpager and sleeps + for a while waiting for free pages. Hopefully the pager process + notified by kickpager would make more pages available, by + stealing pages from someone else. If there are several + processes allocating free pages, they will enter this region + too, until the point when one of the checks at :130,133 + succeed. + page.c:154,161 + When memory is considered to be full, the process would loop, + waking up the pager and sleeping for a while repeated times, + until the pager gets free pages. This usually requires disk or + network I/O and can be a really slow process. Now, if the + caller is servicing a page fault on a segment, it would make no + sense to keep the whole segment locked just to await for a free + page. The segment could be the text of ls and many other ls + processes could perhaps keep on running without the faulting + page. What the author does is to let freepage release the lock + of the segment (:138), and tell the caller (:139) that the + segment is no longer locked. For example, in fault.c:99,101, + fixfault would notice that it had to wait, and did loose the + segment lock, for slow I/O. It would fail and let fault retry + later. + page.c:166,169 + Got some free pages (according to freecount). Get one from the + free list. Due to processor caching issues, not all pages are + the same. The algorithm assigns ``colors'' to pages, so that + it's best to allocate a ``red'' page frame for a ``red'' page + (:127). Only a few colors are needed (like colors in a map). + To remind you, this is because the processor (hardware) cache + sometimes use the same cache entry depending on the (physical, + or virtual, depending on the architecture) address of a page. + For example, a processor with two cache entries (ridiculous, + but just an example) could use entry 0 for even page frames, + and entry 1 for odd page frames. If a process is using a data + structure between two pages, it is better to allocate even page + frames to even pages, and odd page frames to odd pages. This + way, the two pages can be kept in the processor cache at the + same time. I hope you get the picture with this silly example, + but note that for the Intel, getpgcolor always gives 0 as the + color (../pc/mem.h:120). So the author does no page coloring + for the PC. + page.c:171,176 + No free page for our color, just take the first one. ct is used + to control the cache. By now, note that PG_NOFLUSH or PG_NEWCOL + is set depending on whether a page of the right color was found + or not. + page.c:178 + The page removed from the free list. + page.c:180,187 + The author checks that the page was indeed free (no + references), and removes it from the cache. This page could + belong to a different image and be placed on the free list by + the pager. In any case, the page is going to be used for a + different purpose now. + page.c:188,189 + The page has a cachectl array with an entry per processor. For + all processors, entries are set to either PG_NOFLUSH or + PG_NEWCOL depending on the page color. On Intels, cachectl is + not used, but other architectures might use it to determine + whether the cache entry for the page should be flushed or not. + This is because there are architectures that fill up the cache + using virtual addresses, if a page has changed its virtual + address (the frame is reused for a different page), its entry + on the cache might need to be flushed if the hardware wouldn't + notice that and flush the entry automatically. + page.c:193,197 + Zero the memory if requested. + +Paging out + + kickpager() Starts the pager process or wakes it up. + + swap.c:90,101 + kickpager is used to ask the pager to do its job. Its purpose + is to get some free pages. Because of the static started, the + first time the system is running out of (physical) memory, a + kernel process is started to run the pager function[248]10.3. + Next times, only a wakeup for swapalloc.r is issued. Let's see + pager. + + pager() Main routine for the pager process. + + swap.c:103,118 + pager keeps running under the loop to get more free pages. To + prevent it from running even when there is free memory, the + author makes it sleep at line :118. It will stay there until + awakened by a process calling newpage. When the first call to + kickpager starts the pager, needpages can prevent the pager + from sleeping. + swap.c:120 + The pager will not sleep until it has managed to free some + pages. + swap.c:122 + swapimage.c is the channel to the swap file (or partition). If + there is such channel, some pages can be paged out to swap + space (i.e. copied to the swap file and their frames reused as + free memory). + swap.c:123,125 + p is going in a round-robin fashion among existing processes. + All configured process entries are scanned (:133,114). + swap.c:127,128 + Dead processes are not using memory and are skipped (note that + dead is not broken), and kernel processes are given kept + untouched (they run within the kernel, don't they?) + swap.c:130,131 + If canqlock acquires the look, it is the turn for this process + to donate some of its pages to the Plan 9 cause. Otherwise, the + process is touching its segments. Instead of blocking the pager + process, the author chooses another victim. Although the + algorithm is not fair, it is better to use an unfair algorithm + than it is to let the pager block while free memory is needed. + swap.c:133,137 + Starting to iterate over the process segments, seeking for + pages to steal. As soon as needpages says so, no more pages are + stolen. The segment lock is kept for the whole search. + swap.c:139,160 + Got a segment for the process (an used entry). Only segment + types mentioned in the switch get pages stolen. pageout is the + page thief. When it is a text page the one stolen, the `ps' + state is not changed (because the page comes from the text file + (read-only) and there is no need to maintain the process locked + in pageout for too long. For data pages (including stack and + others), the `ps' state is set to Pageout during the call to + pageout and maybe later to I/O, during the call to executeio. + Let's defer a bit pageout and executeio. As you just saw, all + (user) processes are candidates to get their pages stolen in a + round-robin manner. + swap.c:164,174 + If there is no swap file defined yet, freebroken is called on + terminals to kill broken processes and reuse their memory. On + CPU servers, killbig is used instead. A message is printed to + let the user know that either more memory should be added to + the system, or a swap file configured. The call to tsleep + prevents the message from appearing too frequently. + + pager + killbig() Kills a big process and reclaims its memory. + + proc.c:1156,1190 + killbig locates the process with the biggest memory image (sum + of the lengths for its segments), and kills it. The author + knows this is not fair, and prints a diagnostic to let the user + know. However, the author hopes that by killing this big + process, the CPU server could get out of the out of memory + condition. Nevertheless, the injured user could ask the CPU + server administrator to configure a swap file if that's the + problem. The action really killing the process is a procctl + order of exitbig, so the process will kill itself later when it + checks its procctl. But in any case, as the memory is needed + now, mfreeseg is called to release the memory of all user + segments in that process, so that it be available now; mfreeseg + is discussed later. + + pager + pageout() Steals pages from a process segment. + + swap.c:179,180 + pageout tries to steal pages from the given process and + segment. + swap.c:186,187 + When the author services page faults, lk is acquired and + newpage can be called. Now, newpage can awake the pager which + can try to get the lock to do some page outs--skipping locked + segments, (note that this actually means Pte map locking, and + not seg locking). + By using canqlock, the worst thing that may happen is that + other segment is used to steal pages from, not a big deal when + compared with a deadlock. You should note that the pager does + not want to block as it should get free memory soon. Besides, + by avoiding races against page operations on the locked + segments, the author can forget about race conditions in that + respect. + swap.c:189,192 + steal is non-zero while procctlmemio (devproc.c:981,1049) is + doing I/O on segment memory. That is precisely to prevent the + pager from paging out segment pages under devproc feet. + swap.c:194,198 + Only if canflush, are pages stolen from this segment. As + canflush adds an extra reference to the segment, putseg must be + called to release the reference. The reference avoids segment + deletion while it is being used to page out some of its pages. + + pager + pageout + canflush() Anyone running on pages from this segment? + + swap.c:235,265 + canflush returns true if canpage returns true for all (alive) + processes using the given segment. When there is more than one + reference, all processes must be searched to find other users + of the segment. + proc.c:283,299 + canpage returns true only if the process is not running, and it + sets newtlb to true in such case. + What is going on? If the process is running (pager is just + another process, and there can be multiple processors), the + author refuses to check if the page is really being used or + not. It is more simple to remove pages from processes not + running (note the mach check!). When the process runs again, it + will notice the newtlb flag and flush its MMU (because page + translations are going to change in pageout). So, only when + none of the processes using the page is running, can pageout + steal the page. + What if a process which said it canpage runs after the call to + canpage but before pageout completes? That is no problem, + mmuswitch would notice newtlb and will call mmuptefree to set + as invalid the entries in the MMU page table for every user + page in that process. So, pageout really hurts to the process + affected. Even if it gets just a few pages paged out, it will + suffer many page faults. + + pager + pageout + + swap.c:207,228 + For all (user) Pages in the segment (first and last are used to + avoid scanning all the map entries), if the Page is pagedout + (never paged in, or paged out) it is ignored. If the page has + the referenced bit set, it is forgiven and it has a new chance + to be referenced again before the next pass of the pager for + this page. If the page is not referenced (or was forgiven and + not referenced again before being reached once more), pagepte + steals the page. This is a second-chance paging out policy. If + the author did not forgave pages referenced, pages really in + use by the process could be paged-in soon, and then paged out + again, and the system could end up trashing (it would do + nothing else but to service page-ins and page-outs). + swap.c:225,226 + ioptr points to the current page I/O transaction. If nswppo + page I/O requests are in place, the system refuses to do more + page I/O. I think that the author tries to avoid trashing here + too. If after finishing the current transactions, memory is + still scarce, more page outs would happen. Another good reason + not to do too much I/O to get free memory is that the user is + waiting for his application to run, and the application is + waiting because the processor is being used for the pager too. + + pager + pageout + pagepte() Updates a Pte for a page out, adding the page to the I/O + list. + + swap.c:267,274 + Paging out a page. A pointer to the pointer used by the caller + is passed, so that pagepte can update it for the caller. + swap.c:275,278 + If the page is a text page, it can be paged-in later from the + text file. The caller Page* is cleared and the reference to the + page released. That's all to do here. This is the reason why + psstate was not changed for the process while doing a page out. + Because, in fact, there are no ``page outs'' for text pages, + they are simply discarded. + swap.c:280,290 + For these segments, a copy of the page memory must be made + before reusing its frame. newswap allocates a new disk address + (within the swap file) where to copy the page. + newswap()Allocates space for a page in swap. + swap.c:35,56 + newswap scans a bitmap swapalloc for a zero byte--which + represents room for a page in the corresponding offset for the + swap file. last and top are used to do kind of a next-fit + policy for swap space allocation; last is kept set as the last + slot found at look. Initially, last is initialized to point to + the start of the ``byte-map'' in swapinit. Line :51 is marking + the byte as allocated. The author trades space for time, by + using bytes and not bits in the map. It is more simple to use a + whole byte than it is to use a bit (it should be masked and + checked). Memory is cheap these days. + By the way, now you can understand why fault.c:122,123 called + swapcount to account extra references for Pages that had + swapimage as their image. swapcount (swap.c:84,88) returns the + ``1'' or the ``0'' in the swap ``bytemap'' entry for the page. + So, code in fault.c:122,123 accounts one extra reference for a + swap file Page if the swap bitmap states that such page is + being used. As you will see soon, when (non-text) pages are + paged out, their ref could reach zero. + swap.c:291,292 + newswap returns -1 (in two's complement, note the unsigned + return value from newswap) when there are no more free swap + slots for pages. The routine refuses to page out if there is no + place to copy page contents. + swap.c:293 + cachedel removes any cached page for the swap image at disk + address daddr. Remember that lookpage can try to get a cached + page for a disk address? In the past, this disk address could + haven been used to keep other page, and it could be that the + palloc hash (cache) still has a cached pages pretending to be + the contents for this file slot. No longer the case. The pages + caching daddr would still be in the free list, but it would not + be in the hash list any more. + swap.c:295,298 + In the same way, the page being paged out can be linked into + the palloc hash, as a cache for part of its image. uncachepage + removes the page from the hash, and sets its image and daddr to + zero. Now the page is no longer for its old image--uncachepage + expects the page to be locked. + swap.c:300,317 + The comments say it all. But note that PG_ONSWAP is set (see + pagedout). Although the page is not yet sent to the swap file, + the kernel considers it as swapped out. The space for the + pointer to the Page in the segment is used to keep the daddr + for the page in the swap file. + Now pagepte completes and pageout would perhaps loop adding + more I/O requests to iolist by calling pagepte more times. When + the configured I/O limit is reached, or when the segment is + entirely scanned, pageout completes too. Later, lines :154,156 + would call executeio. + + pager + executeio() Performs I/O for page outs. + + swap.c:331,366 + All I/O requests placed in iolist are serviced at a go. For + each page set in iolist, kmap is called to set a temporary + mapping so that write can be called for the swap file channel + to write the page contents. The segment reference to the page + is not released (putpage called) until write returns; i.e. + after page contents are safe in swap. Besides the segment (Pte + entry) reference, there was another extra reference which is + removed at :361. As the process had the segment unlocked before + executeio executes, the segment could call putpage on its own. + If you look at putpage, (page.c:209,238), you will see that it + checks the PG_ONSWAP bit and calls putswap to release pages + with the bit set. However, pagepte did set the bit in the + Segment pointer to the page, but not in the iolist pointer to + the page. Therefore, the putpage call from executeio really + does a putpage. + By deferring page I/O requests until after the segment is + unlocked, the time the segment lock is held is reduced a lot + (I/O takes a long time). In the mean time, processes could + service other page faults for the segment. This is very + important since mmuptefree clears page table entries for the + process affected and it will have to service many page faults + for the segment. + As a final comment, note that the PG_MOD bit is not checked to + avoid calling write for a page which has not been modified + since it was last read (e.g. from the data section of the text + file). Although that could save some I/O, the author probably + thinks that it is not worth to do so. Take into account that he + duplicate made for data pages before they could be written + helps here. + Should the author change his mind in this respect, pages backed + up by swap space would need to keep swap space allocated even + while in memory, so that pages not changed since their last + page-in could be discarded without I/O. + +Configuring a swap file + + syswrite + conswrite + + devcons.c:847,864 + A swap file is configured by a write to #c/swap. Usually, the + string written is the number of an open file descriptor for the + file to be used as a swap area. A write of the string start + would kickpager instead of configuring the swap file. For CPU + servers, only the boot user (Eve) can configure a swap + file--otherwise, any user could read memory from other user's + processes by configuring a swap file and forcing the server + into a low-memory condition. Since terminals run processes on + the name of eve, the author does not check anything for them. + The work is done by setswapchan. + + syswrite + conswrite + setswapchan() Configures a swap channel. + + swap.c:374,403 + The important work is done at line :402. Lines up to :386 take + care of unconfiguring a previous swap file if it was not used + (All nswap pages are free); the new file will be used instead. + Lines :392,400 limit the number of pages in the swap file to be + those that fit in the partition. Surprisingly, if a previous + swap file existed, nswap would only decrease, and not increase. + It will always be at or below the value configured at boot + time. By the way, the check for `M' is because all `files' come + from the mount driver--this is a CPU/terminal kernel; so, if + the device is not #M, it is likely to be a kernel device who + provided file, and that's usually a disk partition. Perhaps a + more explicit check against the storage device could be + made--but what about using a kfs file? Hint: what if kfs data + was swapped out? + +Paging in + + You already saw most of the code needed to page-in some pages for user + segments, while learning how are pages added to segments: Plan 9 uses + demand load for pages. Let's see now the part of the code we didn't + read. + + To remind you, fixfault called pio to do a page-in for the faulting + page. You saw how the cache for the image (or the swap file image) was + tried by pio, and how pio worked when there was not a Page for the + page. + + trap... + fixfault + pio + + fault.c:253,269 + Now, when it appears to be a pointer to a Page hanging from + loadrec (from the segment map), the page faulting was paged + out. Moreover, the page faulting is not a text page because + text pages have their Pages deallocated on page-outs. So, the + page must be read from the swap file pointed to by + (swapimage.c). Remember that at this point in pio, new has a + fresh page (frame) to be used for the faulting page. + The calls to qlock/qunlock within the error recovery block at + lines :258,259 seem to be to wait until sure that no other + process is holding the lk lock. This routine acquires that + lock. faulterror can call pexit to kill the process. Therefore, + if the I/O fails to do a page-in, the process is killed after + nobody is running within the critical region. + fault.c:271,286 + During the call to read (which can block), the segment was + unlocked. Another process could initiate a page in. This case + is easy to check because it that did not happen, loadrec would + still be *p, the entry in the Segment. If loadrec differs, that + must be because at line :290 the other process did set the + entry to the page it allocated. The first one getting past line + :269 wins. If another process did the page-in, the routine + releases the page allocated (and read!!) by this process: all + done. It could also be that the pager stole this page, which is + known because pagedout returns true (and *p changed too!). In + this case the page has to be paged in again, hence the goto. + Perhaps the author could save some reads by allowing at most + one process to do the read for a page-in. Nevertheless, it is + not clear that would be worth because several processes must be + faulting on the same page for it to be worth. Besides, the + saved time would be minimized because of caching. Remember? + Measure and then optimize, not vice-versa. + +Weird paging code? + + If you are curious, you already noticed how there are still portions + of paging code that remain to be read. In particular, + + trap... + fixfault + + fault.c:113,117 + This code restores the hardware MMU permissions for the + faulting page when it is a read-fault and copymode is zero and + avoids doing any other thing. + fault.c:127,140 + This code does something which is not calling duppage when + there is more than one reference to the Page (including as + references pages swapped out). If you look at the code, it + allocates a new page and calls copypage to install a + translation to a copy of the faulting page. + + To understand what is going on, you must read dupseg first. That + procedure clones a segment during a rfork. + + Duplicating segments + + sysrfork() + dupseg() Duplicates or shares a segment. + + segment.c:143,144 + During rfork (sysproc.c:107), dupseg is called to duplicate a + segment or request that it be shared with the parent process. + seg is the process segment array. The routine is expected to + return a pointer to the duplicated/shared segment. + segment.c:153 + Segments are duplicated one way or another depending on the + kind of segment. + segment.c:154,159 + For segments that are read-only (text), shared (SG_SHARED and + SG_SHDATA), or physical memory (which is shared), the reference + count is incremented and the parent's segment is used as-is by + the child. It does not matter what share says. + segment.c:161,169 + Stack segments are never shared. newseg creates a new stack + segment with the same base and size as the original segment. + This new segment is still empty (although it should be a copy + of the parent's stack). + segment.c:212,219 + Later, dupseg calls ptecpy to copy each Pte in the original + segment to the new (duplicate) segment. Let's see what happens + to other segments before looking at ptecpy. + segment.c:171,186 + For BSS segments (and MAPs), one of two things can happen. + If the segment is to be shared, and nobody is sharing the + segment (its reference is one), the segment type is changed to + be SG_SHARED. From now on, calls to dupseg for this segment + would just add another reference, as seen before. You now know + that a SG_SHARED segment is a BSS or MAP segment that is being + shared. The routine adds the extra reference and returns the + segment as the duplicate one. + If the segment is not to be shared (!share) a new segment is + created, and later, ptecpy would copy Pte entries for the new + segment. Let's see now ptecpy. + + sysrfork() + dupseg + ptecopy() Copies PTE entries. + + page.c:442,464 + ptecpy is an innocent looking function, which allocates new + Ptes for the duplicated segment and iterates through all (used) + Pages in the old Pte. For each entry used, if the page was + swapped out, dupswap is called. But otherwise, an extra + reference is just added to the Page, and the the Page* in the + destination entry is copied from the source entry! Noticed that + the segment is being duplicated, although Pages are shared? + Although the duplicate segment was expected to get a copy of + the pages, it gets the same pages. What's going on? + The duplicated segment has no real MMU page table entry + updated, so it is going to page fault on the pages ``copied'', + although its entries are set in its Ptes. + + trap... + fixfault + + fault.c:126,141 + When the process later has a page fault due to a write on the + ``copied'' BSS segment, the page has more than one reference + (for read accesses, the MMU entry is given read permission and + nothing else is done). + In this case, fixfault knows that the extra references are + there because although the page is being shared, it should not + be shared officially (pages really shared on shared segments + have a reference count of 1, it is the Segment that has the + reference count bigger than 1). This is called ``copy on + write'', or COW. When the segment is duplicated, the segment + and its Ptes are duplicated, but the pages are shared (with a + reference count bigger than 1). On a (write) page fault, the + page is copied (copypage) to a new page frame (new), and the + new page is given to the faulting process. there is a call to + putpage because this process is no longer using the shared copy + of the page. In figure [249]6.5 you can see a COW segment and a + shared segment. + + CAPTION: Figure 6.5: A copy on write (or copy on reference) segment is + like a copy of another segment: but both segments share unmodified + (unreferenced) pages. This is not to be confused with a shared + segment. The figure shows how each Page has an associated page frame. + + If other processes copied the segment (on write), the number of + references in the page after putpage is still greater than one, + and more copies will be made, if the page is referenced. If no + other process is sharing (copying on write) the page, its + reference is one, and lines :143,150 would execute instead: the + page is used as is, after saving a copy for the image cache and + restoring permissions in the MMU entry. + The check for copymode at line :113 is deciding when to really + copy the page. I have been saying that the page is copied on + write. I lied. Only when copymode is not-zero is the kernel + restoring MMU permissions (without any copying) for read + faults. When it is zero, even a page fault for reading causes + the page to be copied. So, if conf.copymode is zero, Plan 9 + does copy on reference, otherwise, copy on write is used. + copymode is zero unless archinit or mpinit set it to one, which + happens only for multiprocessor machines. So, Plan 9 uses copy + on reference for monoprocessors and copy on write for (Intel) + multiprocessors. + + NOTE: Why? + It is clear that the copied segment has all its MMU + translations invalid; but what about the original segment + copied on write? Any write to its pages should also cause a + page fault, but since the segment was read/write, translations + would still have write access in the MMU. + sysproc.c:182,187 + Is it clear the comment now? All translations are set invalid + by flushmmu. Page faults for read would just repair the MMU + translations. Page faults for write would copy the COW pages. + Although it would be faster to downgrade the translations to + read-only for COWed segments, the author prefers to keep the + code simple. Should this be a performance problem, perhaps + flushmmu would be replaced by a more clever routine which could + downgrade entries too. + + sysrfork() + dupseg + + segment.c:188,211 + Ignore the data2txt thing. If the segment is to be shared, add + a reference to it and change its type to SG_SHDATA; you now + know what's a SG_SHDATA segment. If the segment is not being + shared, but copied, COW is used and a new segment is created as + before. The difference with respect to COW for BSS segments is + that the image is added an extra reference and attached to the + segment too. BSS segments have their storage initialized to + zero, and they are never paged in from any image (well, they + are paged in from swap, but you know how that is done). On the + other hand, data segments page their pages in from the image + corresponding to the text file with initial contents for the + data segment. Even though the segment is COW, the copied + segment should also page in from the image those pages which + have never been referenced. So, the segment must be attached to + the image too. Besides this reason, it is good design to keep + the copied segment attached to the same image, as it would be + if it was the original segment: it is a copy, isn't it? + segment.c:189,190 + Back to the first two lines, you must read a bit of devproc to + understand what is going on. + procctlmemio()Does I/O to memory of a process. + devproc.c:998,999 + If procctlmemio is servicing a write for the text segment, it + calls txt2data. + txt2data()Replaces a text segment with a data segment. + devproc.c:1051,1078 + txt2data takes a text segment and replaces it by a data + segment. The data segment is a regular SG_DATA segment but, if + the text segment was the one in seg[TSEG], the entry in TSEG + now contains an SG_DATA, which is not usual. As a data segment, + it accepts writes, and that seems to be the reason why the + author is replacing an SG_TEXT with an SG_DATA. Although the + author could have set a mode field in Segment, and provide some + means to change it, it is more clear to have the type of the + segment determine what can be done to the segment. As this kind + of write seems to be most useful for debugging, it is not + likely to be a frequent operation and its efficiency is not an + issue. + It is useful to be able to write to the text segment to change + instructions, and to set breakpoints on it. + segment.c:189,190 + However, if the process forks, the child should get its regular + SG_TEXT segment in TSEG. dupseg knows and calls data2txt to + recover the text segment corresponding to the weird data + segment. + data2txt()Restores a text segment from a replacement data + segment. + devproc.c:1080,1093 + The only thing data2txt does is to recreate the text segment + from the image, as happened before during exec. + + By the way, the checks for ref==1 besides checking share during dupseg + seem to be more of defensive programming; since the segment type would + be changed just the very first time. But I may be missing something + here. + + Terminating segments + + putseg() Drops a reference to a segment. + + segment.c:83 + When a segment is being released, putseg drops the reference to + it. + segment.c:91,100 + Segments and images are linked circularly, the convention is to + lock the image before the segment. If the last reference to the + segment is being released, it will go away and the image should + no longer point to the segment. In this case, i->s is cleared. + segment.c:108,123 + The last reference is going. The routine clears this thing up, + including a call to putimage, if there is an image attached. + putimage does not call to putseg to release its reference to + the segment. You know why, don't you? + + putseg + putimage() Drops a reference to an image. + + segment.c:385,391 + putimage releases the image. It does nothing for images with + notext. You already saw in the starting up chapter that notext + was set for the first process text image; it is also set for + the swap image by swapinit and for the fscache image used to + cache remote files in cache.c. + segment.c:394,426 + For images with ``text'', after their last reference is gone, + their QID is cleared, and their channel to the text is closed. + The Image is also removed from the Image hash table and linked + to the free list (attachimage would no longer find this image + when searching for other users of the same text). One thing to + note here is how the channel is not really closed here, but + placed into freechan (which is resized on demand) to be closed + later. Closing a channel may block and also may take a long + time. The author wants that to happen after all locks have been + released. + + attachimage + imagechanreclaim() Releases channels used for images (as well as + images). + + segment.c:358,382 + imagechanreclaim is the routine actually calling close for + these channels. It is called from attachimage. Read the comment + regarding locks, it is very explicative. Although keeping these + channels open require file servers to keep resources that are + not really useful ( channels are about to be closed), the + author prefers to close the channels on calls to attachimage + rather than after calling unlock in putimage. One fine reason + can be that putimage is also called during page faults (which + already may take a long time). Perhaps the pager could be also + in charge of closing image channels. + By the way, you now know why imagereclaim puts pages instead of + images to get some Image structures released, because pages + keep the cached contents of the image and the image will not go + away until all its pages have been released. + + putseg + + segment.c:112,115 + Back to putseg, freepte releases the Pages used by the segment. + + putseg + freepte() Releases pages in a Pte. + + page.c:478,516 + For physical segments, a pgfree function is called to + deallocate pages (in the same way that the pgalloc routine was + used by fixfault). Besides calling pgfree, the Page reference + count is decremented and it is freed if no more references. + putpage is not called, because the physical segment allocates + and deallocates pages in a rather specific way. + page.c:508,514 + The usual thing. putpage is called for all Pages found in the + segment. + + putseg + freepte + putpage() Releases a page. + + page.c:208,238 + if the page was swapped out, p is not a pointer to the page, + but a swap address. + putswap()Releases a swapped out page. putswap (swap.c:58,73) + marks the swap page as no longer allocated in the swap + ``bytemap''. + Otherwise, p can point to a real Page, and reference counting + is used. If the image for the page is not swapimage, the page + is linked to the tail of the free list, otherwise it is linked + to the head. Since pages are allocated from the head, the + author is trying to keep the page in the list for a longer time + if the page still caches part of a image. Since the swap image + is just used as backing storage, their pages are to be reused + soon. It should be clear now, but note how the page free list + is actually used as a cache. + Finally, the author wakes up a process that was sleeping + waiting for pages--if any. The reason to wake up a sleeping + process is that there is now a free page available for + allocation (Remaining requesters could still be blocked in + palloc.pwait, only one of them did pass and sleep in palloc.r). + The reason not to issue the wakeup when no process is sleeping + is that in that case, nobody is waiting for memory. + Nevertheless, wakeup would no nothing in that case and calling + it wouldn't hurt, or did the author measure that it would hurt + performance? Or am I missing something here? + + Segments are usually released by putseg, however, there is another + routine (the one called by killbig, which you already saw) that is + called to release memory held by a segment. It is also used by a + couple other routines besides killbig. + + mfreeseg() Releases the memory used by a segment. + + segment.c:503,536 + First, mfreeseg scans all entries in the segment that are for + the pages starting at start. Unused map entries are ignored + (they have no memory to free); all entries in the segment Ptes + are set to nil and pages kept linked at list. + segment.c:537,551 + Second, mfreeseg calls putpage for all pages linked (all + segment pages). Before doing so, procflushseg is called if the + segment is shared. The reason is that when the segment is + shared, page reference counts are one, but pages should not go + away before letting all processes using the segment know that + the segment memory is being released. Other processes using the + segment could be even running right now at a different + processor. + + mfreeseg + procflushseg() Flushes MMU for processes using the given segment. + + proc.c:973,998 + procflushseg iterates through all processes, searching for seg + entries with the s segment. newtlb is set for all processes + with such a segment, so that its entries are invalidated before + it runs again. Besides, (:991) if the process is running at any + processor, flushmmu is set for that processor and nwait + incremented. + proc.c:1007,1001 + If nwait was not zero, the current process waits until flushmmu + is reset to zero for all processors. The current processor can + only `kindly request' to other processors that their MMU + entries be flushed, they are running and they will flush such + entries when they notice the flushmmu flag. Hopefully, that + will happen soon. + + Segment system calls + + You now know how typical text, data, bss and stack segments are + created, copied during rfork and how are page faults serviced. That is + most of what you should know about memory management. However, there + are several system calls related to memory management that remain yet + to be seen. + +Attaching segments + + syssegattach() Entry point for the segattach system call. Attaches a + new segment. + + sysproc.c:614,618 + syssegattach is used to create a new memory segment. System + call arguments are passed verbatim to segattach. + + syssegattach + segattach() Attaches a new segment. + + segment.c:600,601 + It is segattach who does the job. + segment.c:607,608 + va is given as zero when segattach should choose the address + where to map the segment in the process address space. If it is + not zero, the author checks that the address is not a kernel + address. I don't know the exact reason for the ``BUG'' comment, + but it seems to me that the author plans to be able to attach + segments within the address space of the kernel. + segment.c:610,611 + Checking that name is a null terminated string at existing + virtual memory. + segment.c:613,615 + sno is the slot for the new segment. The first empty slot is + used. The check for ESEG at line :614 is ensuring that the + ``extra segment'' used during exec is kept available. + Otherwise, the process could not use sysexec. + segment.c:617,618 + No more segments for this process. + segment.c:620,622 + len is now an integral number of pages. + segment.c:624,642 + The comment is very descriptive. It is very likely that a big + hole exist in virtual memory right below the user stack. Most + checking is done by isoverlap. By the way, wouldn't it be + better to ensure that virtual addresses used by ESEG are kept + unused? It doesn't matter too much because that portion of the + user address space is used while the maps are set for the + temporary stack mapping. + isoverlap()Would the segment overlap with an existing one? + segment.c:554,571 + isoverlap must iterate through the whole segment array for the + process, checking that neither va nor newtop are contained + within any segment. During all this time, seg is not locked. + However, only the current process could deallocate its seg + entries or attach new entries, and the current process is + currently doing the segattach, so the lock is not really + needed. Nevertheless, the lock could prevent future BUGs, in + case the author changes his mind and uses segattach for a + non-current (not up) process. + segment.c:644,646 + A hole found, isoverlap is called once more after rounding va + to a page boundary. Perhaps va should be truncated before line + :634, and these lines avoided. Besides, it is not clear for me + why Esoverlap (and not Enovmem) is raised, although the author + knows why, I think that Enovmem could be perfectly raised here + too. + segment.c:648,650 + name is the segment ``class'' specified by the user. On each + machine, an array of physical segments is kept at physseg. If + the segment class name matches the name of one of these + physical segments, the routine continues at :653. Otherwise + Ebadarg is raised. You see how a segattach can only be done for + segments declared in physseg. By the way, since the found label + is used only to avoid returning Ebadarg, perhaps an if could + have been better. The code is clear anyway, isn't it? + ../pc/segment.h:1,8 + For Intel PCs, the only known segments are ``shared'' and + ``memory'' (there are more ones, as you will see). But for + other architectures, physseg may contain exotic physical + segments (read the manual page). I think that the name is phys + because usually, processes attach to segments representing + physical memory like device-provided memory, memory locks, etc. + ../port/segment.c:654,664 + Unless the segment length be bigger than SEGMAXSIZE, the + segment is attached. newseg is creating the new segment, it + will be either a SHARED or a BSS segment, and page faults with + zero fill it on demand. + + Physical segments + + addphysseg() Adds a new segment class. + + segment.c:573,598 + I told you that ../pc/segment.h had just a couple of ``shared'' + and ``memory'' segments (classes) defined. There is a routine + addphysseg which is called by device drivers to declare the + existence of physical memory segments important for them. For + example, in ../pc/vgas3.c:103, the S3 video card driver calls + addphysseg to add an entry to physseg, with attribute + SG_PHYSICAL (physical memory used for the card) and name + s3screen (the video memory). This call is done by s3linear, + which is the S3 VGAdev procedure used to enable a linear mode + in the card (see ../pc/devvga.c and ../pc/screen.c). After this + segment is added by calling addphysseg, a segattach can be done + for s3screen to get to the video memory. + The routine addphysseg only checks that there is free room + after the initialized entries (those with a name) and before + the last entry (which must be a null entry) to add the new + segment. Should there be space, the new segment given is linked + into the array. + +Detaching segments + + syssegdetach() segdetach(2) system call. Detaches a segment. + + sysproc.c:621,631 + syssegdetach is the counterpart of syssegattach. It detaches a + segment from the address space. The seglock must be acquired + now. Routines that do not want seg entries to disappear under + their feet acquire this lock too. + sysproc.c:633,644 + The first argument is an address contained in the segment to be + detached. The seg array is searched until the entry number (i) + is found and s is set to the segment being detached. + sysproc.c:646,651 + arg is a pointer to the user arguments for the system call, + therefore it resides within the user stack. if this address is + contained in the segment to be detached, it is the stack + segment the one detached. In this case, the system refuses to + detach the segment. A process always needs a stack. Although + the check is nice, perhaps a check against SG_STACK would be + more clear. + The system does not seem to refuse detaches for the text + segment, although the manual page suggests so. + sysproc.c:652,660 + The segment is released by the call to putseg. + By the way, perhaps a segdettach routine could contain most of + syssegdetach code, as it happens with segattach. + + syssegfree() segfree(2) system call. Releases (part of) a segment. + + sysproc.c:664,686 + syssegfree releases (note the call to mfreeseg) part of the + memory held by the segment. This routine calls seg instead of + locating the segment itself to find the segment containing from + and lock it. Perhaps the routine could be generalized to return + the index for the segment in the seg array so that others (e.g. + syssegdetach) could benefit from it too. What happens to the + portion of the address space released depends on the kind of + segment. For instance, should it be a BSS segment, pages would + be later zero-filled on demand. + +Resizing segments + + syssegbrk() segbrk(2) system call. Resizes a segment. + + sysproc.c:588,608 + syssegbrk resizes the segment. Only SHARED, BSS, and SHDATA + segments can be resized. The reason is that text and data + segments correspond (and are paged from) an image of a text + file. Only for ``anonymous memory'' does brk make sense. ibrk + does all the work. + + syssegbrk + ibrk() Resizes a segment. + + segment.c:431,454 + addr is the new end address for the segment. If should be at + least the segment base. The comment says that BSS might be + overlapping the data segment, in which case :449 is checking + that addr is smaller than base for a BSEG and addr is bigger + than base for the DSEG (otherwise an error is raised). However, + segbrk finds the first segment where addr is contained, and + :448 would never be true. + Nevertheless, in a previous implementation of segbrk (note + :sysproc.c:688,693), the segment resized was always the BSS + segment, in which case :448 could be true for old Plan 9 + binaries and lines :448,454 would leave addr being the start of + the BSS segment. Perhaps it would have been better to let + sysbrk_ do the check, and either keep ibrk assuming that addr + always resides within segment bounds, or keep ibrk checking + that addr is within the segment. The reason for doing so is + that should sysbrk_ disappear, the weird BSS check in ibrk may + be forgotten and kept there. + segment.c:456,463 + The new top and size for the segment is computed. If the + segment is to shrink, mfreeseg releases the (now unused) memory + of the segment. Since segment base and top are not updated, any + page fault on the released part of the segment would make the + segment grow again. Perhaps lines :494,495 should be copied + before line :462. Although the current behavior is perfectly + reasonable (and compatible with what is said in segbrk(2).). + segment.c:465,468 + The segment is growing. Since the only segments resized + (sysproc.c:600,607) are SHARED, BSS, and SHDATA segments, which + have the swap file as their backing store, no resize is allowed + if there is no free swap space. + segment.c:470,478 + The whole list of segments is scanned searching for a segment + containing newtop. If newtop is not contained within other + segment, the space from the current top up to newtop is + available. However, there could be a case when there is a + segment starting after top, but ending before newtop, in which + the check would miss that there is another segment overlapping + the portion of the virtual address space being allocated. + Perhaps the check could be changed to see if base for any + segment is between top and newtop. + segment.c:480,492 + mapsize recomputed and map is reallocated to have enough space + for the new Ptes--map could be using the small ssegmap array. + segment.c:494,497 + Segment bounds updated. Segments grow, but they really never + shrink--only memory is reused if they are pretending to shrink. + +Flushing segments + + syssegflush() segflush(2) system call. Flushes a segment cache. + + segment.c:681,729 + syssegflush does a flush of the processor cache for memory + within the segment. This seems to be used only by instruction + simulator commands. The routine flushes a range of the user + address space, which may spawn several segments. For each + segment, pteflush is called to flush Ptes affected. + + syssegflush + pteflush() Flushes the cache for a Pte. + + segment.c:667,678 + pteflush sets the cachectl entry for the page (if not paged + out) to PG_TXTFLUSH. As you may remember, this means that for + several architectures (not the Intel), the processor cache + entries for the given pages may be flushed later by the + flushmmu call at :727. + +Segment profiling + + segclock() Update segment profiling counters. + + segment.c:731,745 + Not really a system call, but each time the clock ticks, if the + processor was running user code, ../pc/clock.c:76,79 would call + segclock giving the current saved program counter for the user + process. The call is made after adding to the word in the + bottom of the user stack the number of ticks in a millisecond. + The kernel is maintaining a ``clock'' for the running process + in the bottom of its user stack. If profile is set in the TSEG + for the process, segclock adds the time passed to the value in + s->profile[0]. Moreover, if the program counter for the user + was within this segment, it is converted to a relative offset + within TSEG and another time counter incremented. The + >>LRESPROF is used to have one time counter per LRESPROF + instructions in the text segment. + If you think of it, the author is filling up profile with an + array of clocks for the process. The first clock counts the + time the process has been executing (one ms added every time a + ms happens and the process was running), following clocks have + the time spent by the process within the first, second,... + group of LRESPROF instructions. The user can later inspect + these clocks and learn where is his program spending time. This + is crucial to let the user know what should be optimized, and + what not. + + Intel MMU handling + + During the chapter about system startup you already read some code for + MMU handling in the Intel PC. In this section you will be reading the + code which has been used by the machine independent code for memory + management, and was not discussed previously. + +Flushing entries + + flushmmu() Flushes MMU translations. + + ../pc/mmu.c:80,89 + flushmmu was called whenever the page table was changed, and + translations should be updated. Remember that the TLB may keep + cached entries. All it does is to set the newtlb flag and + switch to the current page table. On the Intel, a load of the + page directory base register flushes the TLB too. + + flushmmu + mmuswitch() Switches the address space in the MMU. + + mmu.c:110,127 + mmuswitch (in this case), notices the newtlb and calls + mmuptefree to flush the current set of entries. Later, the + switch is done. As you should know by now, if the process has a + mmupdb installed, that page table is used, otherwise, the + prototype page table for the processor is used. The virtual + address of the Page used to keep the first level page table is + used to access its entries, and its physical address is used to + set the pdbr (aka cr3). + One important thing here is that the routine maps the Mach + structure (together with the small scheduler stack) for the + current processor at MACHADDR. PDX is getting the index in the + first level page table for the virtual address MACHADDR. Each + processor has at MACHADDR a map of its Mach, as you saw in the + starting up chapter. + + flushmmu + mmuswitch + mmuptefree() Releases translations. + + mmu.c:91,108 + mmuptefree starts with the Page noted in mmuused, and iterates + through the whole set of pages linked through the next field. + For each such page, its entry in the pdb is set to nil (i.e. + invalid). pdb is set to be the virtual address of the mmupdb, + to update later its contents. The Page keeps in daddr the index + in the PDB for it. mmuused is a list of Pages used to keep + secondary page tables for the process. So, mmuptefree is just + clearing (invalidating) entries in the first level page table. + Al those pages are linked later into mmufree. All second level + page tables linked through mmuused are free now. The process + will have to suffer page faults to get new second level tables + again. This time, the machine independent MMU code will + instruct mmu.c to fill up the entries according to changes in + the Segment entries. + Can you see how the portable virtual memory data structures + dictate what the machine dependent code should do? Can you see + how they can differ from what the MMU has installed? + dat.h:90,95 + mmupdb, mmufree, and mmuused are just Pages. The fields va and + pa of such pages are used to update entries using the virtual + address space and to get the page frame address for giving it + to either the MMU or to an entry in PD. (By the why, see + ../port/portdat.h:628 if you don't understand why I told you to + look into PMMU and not into Proc). + +Adding entries + + putmmu() Updates a translation. + + mmu.c:195,196 + putmmu is called by the machine independent code to add an + entry to the MMU page table for the current process. This + happens when fixfault is repairing a page fault. How does this + work? + You know that each processor has a prototype page table, which + includes mappings for kernel space as well as an identity + mapping for physical memory. The kernel uses this prototype + page table if the process has not its own one. So, when a new + process is created, it starts using this page table until it + suffers a page fault and fixfault calls putmmu. + mmu.c:203,204 + If the process did not have its own page table, one is created. + mmupdballoc does the job. Following calls to putmmu due to page + faults will find (and use) the existing PDB allocated here. + mmupdballoc()Allocates a PDB . + mmu.c:173,193 + mmupdballoc takes a new Page, either by allocating it (with + newpage) or by using one from a free list at pdbpool. va is set + in the Page as the kernel virtual address for the page frame + and the page is kept mapped for kernel usage (no-op on Intels). + It is initialized by copying the prototype page table from the + processor, which you know was initialized. Initialized PDBs are + placed back to the pdbpool when they are no longer used by the + process, so that their allocation could be faster. Since + newpage is given a nil s pointer, it will keep on trying to + allocate a page instead of returning failure (as it does when + called from fixfault). + mmu.c:205,206 + Back to putmmu, pdb is now a kernel pointer to the PDB and pdbx + is the entry in the first level page table for the virtual + address to be mapped to pa using the Page supplied (note it's + not used on Intels). + mmu.c:208,217 + If there is no second-level page table (entry invalid in the + PDB), must allocate one. They are allocated on demand. Again, + Pages for second level page tables are reused. If there is one + in the free list (mmufree) that is used, otherwise newpage is + called to allocate a new one. clear is set for newpage, so it + is zeroed, setting all entries as invalid. If the page is new, + a kernel map is made, otherwise, the kernel map was already + done at page allocation time. + mmu.c:218 + The entry in the PDB is set as valid, usable for protection + ring 3, and allowing writes. The Intel checks permissions on + the entry in the PDB, and then it checks permissions on the + entry in the second label page table, every time an address is + used (of course, TLB caches such things). + mmu.c:219,221 + mmuused is updated to contain the new page, so that mmuptefree + could know which entries are used. As only a few entries of the + 1024 existing entries are really used, that saves a lot of + time. daddr (not used here as a disk address) is used to keep + the index in the PDB. PDB used entries can be found pretty + quickly. + mmu.c:224,225 + At this point, the second level page table exists. pte is set + pointing to the second level page table. page->va should be + equal to KADDR(PPN(pdb[pdbx])). However, the author prefers to + obtain the pointer through the entry in the PDB, probably to be + sure that things are working properly. The entry in the second + level page table for va is set with pa together with the USER + bit, which says that ring 3 can access the page. When fixfault + calls putmmu, pa is not just the page frame address for va, + fixfault sets some of its offset bits to specify which + permissions should be enabled (e.g. PTEWRITE, etc.), so the + author ORs pa to keep those bits set. + + NOTE: perhaps page's va cannot be used because the second level + page table could be shared? Check that. + mmu.c:227,231 + Again ensuring that the Mach page is mapped, although it should + be mapped already if the PDB did exist, and it will be mapped + by mmuswitch in any case. Just for safety. + +Adding and looking up entries + + mmuwalk() Walks to an MMU entry (and perhaps creates it). + + mmu.c:233,234 + You saw how mmuwalk was called to get a pointer to the entry in + the MMU page table for a given va. If level is 1, the entry + wanted is the one in the first level page table, should it + be 2, the entry wanted is the one in the second level page + table. Other architectures may accept more than two levels + (note the clean generic interface for the routine), but intels + have just two. create can be set to request that the second + level table be created. mmu.c itself uses mmuwalk, and meminit + uses it too to create a prototype table. Unlike putmmu, mmuwalk + does not require up to have a valid current process. + mmu.c:245,247 + table is set to point to the entry in PDB for the given va. If + the entry is nil, and it shouldn't be created, there is nothing + to do. + mmu.c:249,268 + Just two levels on Intels. For level 1, table is the pointer to + the entry. For level 2, if the entry in *table was not valid, a + second level page table is allocated and the entry in the PDB + updated. This only happens when create was set. Finally, table + is set to point to the virtual address for the second level + page table, and a pointer to its entry for va returned. + + mmukmap() Adds a kernel map to the MMU. + + mmu.c:307,308 + mmukmap adds a translation to the MMU page table for a page + within the kernel portion of the address space. You saw how + mmukmap was called during boot time, while initializing memory. + mmu.c:314,318 + mach0 is set to point to the Mach structure for the boot + processor. If it has bit 0x10 set in its cr4 and the processor + is not so old that does not support it, super-pages can be used + (Remember, using entries in the first-level page table to map + 4MB). pse is set if super-pages can be used. + mmu.c:321,326 + If va is not given, mmukmap understands that it is doing the + identity map at KZERO. Otherwise, it is truncated to be a page + address. + mmu.c:328,399 + This loop maps the range of physical memory going from pa to + pa+size-1. The routine can be used both to map a single page + and to map a whole range of (4K) pages. + mmu.c:331 + table is pointing to the first level entry in the prototype PDB + at processor zero. + mmu.c:335,379 + The entry is valid. If the entry had the PTESIZE bit, it was a + map for 4M without using a second level page table (:337,357). + In this case, x is the start of a 4M super- page frame, which + should be the same of pa--at each pass, pa is the physical + address being mapped. pa is set either to the end of the mapped + memory or to the end of the super-page, preparing things up for + the next iteration or for terminating the loop. The loop + continues after the portion mapped by the super-page. If pa is + already pae, all remaining pages to be mapped were already + mapped by the super-page and the loop finishes. + If the entry (:336) did not have the PTESIZE bit, it is + pointing to a second level page table (:360,376). In this case, + mmuwalk is used to get the entry in the second level page table + (note again: processor zero PDB). If the entry is valid, pa is + advanced past the already mapped page. + sync is not-zero when a second level page table entry has been + scanned. + mmu.c:382,298 + The entry was not mapped. If pse says so, a whole super-page is + used to map the desired address. This assumes that all the 4MB + of physical memory (4MB aligned) where pa stands are to be + mapped; hence the checks at line :387. It is very important to + use super-pages since the Intel has different TLB entries for + super-pages and regular pages. By making the kernel use + super-pages, the user TLB entries are not disturbed while + servicing interrupts and system calls. If no super-pages can be + used (or the mapping does not contain a whole 4M super-page), + mmuwalk is used to create the second level entry. pgsz is set + so that :396,397 can prepare the next pass. sync is not-zero + when any entry has been added to the processor zero PDB. + mmu.c:402,407 + mmukmapsync is called if mmukmap was called and either the + mapping was at a second-level page table, or an entry was + updated--you also saw a call to mmukmapsync before. + + mmukmap + mmukmapsync() Synchronizes kernel maps in page tables. + + mmu.c:272,273 + mmukmapsync updates prototype page tables for all processors by + looking at the boot processor page table. It fixes any missing + entry. So, apart of initial memory mappings created during boot + time, any kernel map added later only has to be set at + processor 0. That is precisely what mmukmap does! + Other processors will fault when using memory mapped at a + different processor, but mmukmapsync will notice that there is + a map in mach0->pdb, and will copy such map to the faulting + processor page table. Note also how it flushes the tlb, and how + the page table for the current process is updated to repair any + page fault there. + Faults at these kernel mapped pages will happen only for memory + not mapped initially during boot time. + + Epilogue + + And now what? + + Although we have gone a long way already, you still have devices in + the Plan 9 kernel that remain to be read. You should try to understand + them. + + Besides, Plan 9 is much more than its kernel. For example, the code + for the local file system provider (kfs) is really interesting to + learn how to structure a partition into a set of files. + + It is also illustrative to read the code for user commands, including + the plumber, rio, sam, and acme.
