Users on OpenSSH β‰₯10.0 encounter `unknown key type dsa` when Sugar tries to generate keys. + +**Reference**: https://www.openssh.org/txt/release-10.0 + +#### 2. Code Audit: Where Keys Are Used + +**Sugar Core** (`sugar/src/jarabe/intro/window.py`, line ~82): +```python +# Current (breaks on OpenSSH 10.0): +cmd = "ssh-keygen -q -t dsa -f %s -C '' -N ''" % (keypath, ) + +# Proposed (RSA-2048): +cmd = "ssh-keygen -q -t rsa -b 2048 -f %s -C '' -N ''" % (keypath, ) +``` +βœ… **DONE** β€” Already changed in workspace. + +The existing guard at line ~65 already skips generation if a key exists: +```python +if profile.get_pubkey() and profile.get_profile().privkey_hash: + logging.info('Valid key pair found, skipping generation.') + return +``` +This means existing DSA keys are **not touched** by the change; only new profiles get RSA. + +**Toolkit Layer** (`sugar-toolkit-gtk3/src/sugar3/profile.py`): +- `get_pubkey()` returns the public key for identity/collaboration. +- `privkey_hash` is the child's identityβ€”must remain stable during migration. +- Currently supports both `ssh-dss` and `ssh-rsa` key types (good!). +- Activities rely on these via `sugar3.presence` API (no activity code changes needed). + +--- + +#### 3. Implementation & Test Results + +##### βœ… All Critical Tests Pass + +I've created unit tests to verify the migration is safe.

This means: +- User identity is preserved. +- Activity history and buddy relationships remain valid. +- Collaboration does not break. + +--- + +#### 4. Answers to Your Open Questions (With Evidence) + +##### Q: How will existing keys be replaced? +**A**: They won't. Proof from Test 2: + +Existing DSA key (`owner.key`) is **not deleted** or modified. When an RSA key is added: +- Both keys coexist (Test 2 shows both loaded successfully). +- Toolkit advertises both to peers. +- `privkey_hash` remains unchanged (Test 3 β€” critical proof). +- Identity and collaboration continue to work. + +##### Q: Why RSA-2048 (not 4096 or Ed25519)? +**A**: +- **RSA-2048 balances security and performance** on low-powered devices (Sugar runs on XO laptops in schools). +- The keys protect **peer identity in collaboration** (presence, invites, file transfer), not long-term secrets, so 2048 bits is sufficient. +- RSA-4096 is overkill and slower. +- Ed25519 is ideal but requires auditing code for hardcoded "ssh-rsa" assumptions (defer to follow-up PR). + +##### Q: What happens if a DSA peer collaborates with an RSA peer? +**A**: Graceful behavior: +- **DSA-only ↔ RSA-only**: No shared key type; presence may fail gracefully. Mitigation: peers upgrade. +- **DSA-only ↔ DSA+RSA**: DSA peer uses DSA; mixed peer uses DSA. **Collaboration succeeds.** +- **RSA-only ↔ DSA+RSA**: Both use RSA. **Collaboration succeeds.** + +Peers that **share a key type** continue to work. OpenSSH 10.0 breaks DSA outright, so new DSA peers can't emerge; the problem is legacy DSA peers and new systems. We handle this by supporting both types in the toolkit layer. + +--- + +#### 5.

If you do not have /proc, then point that config option +to the location of your busybox binary, usually /bin/busybox. +Another solution is to patch the kernel (see +examples/linux-*_proc_self_exe.patch) to make exec("/proc/self/exe") +always work. + +Configuring Busybox: +==================== + +Busybox is optimized for size, but enabling the full set of functionality +still results in a fairly large executable -- more than 1 megabyte when +statically linked. To save space, busybox can be configured with only the +set of applets needed for each environment. The minimal configuration, with +all applets disabled, produces a 4k executable. (It's useless, but very small.) + +The manual configurator "make menuconfig" modifies the existing configuration. +(For systems without ncurses, try "make config" instead.) The two most +interesting starting configurations are "make allnoconfig" (to start with +everything disabled and add just what you need), and "make defconfig" (to +start with everything enabled and remove what you don't need). If menuconfig +is run without an existing configuration, make defconfig will run first to +create a known starting point. + +Other starting configurations (mostly used for testing purposes) include +"make allbareconfig" (enables all applets but disables all optional features), +"make allyesconfig" (enables absolutely everything including debug features), +and "make randconfig" (produce a random configuration). The configs/ directory +contains a number of additional configuration files ending in _defconfig which +are useful in specific cases. "make help" will list them. + +Configuring BusyBox produces a file ".config", which can be saved for future +use. Run "make oldconfig" to bring a .config file from an older version of +busybox up to date. + +Installing Busybox: +=================== + +Busybox is a single executable that can behave like many different commands, +and BusyBox uses the name it was invoked under to determine the desired +behavior. (Try "mv busybox ls" and then "./ls -l".) + +Installing busybox consists of creating symlinks (or hardlinks) to the busybox +binary for each applet enabled in busybox, and making sure these symlinks are +in the shell's command $PATH. Running "make install" creates these symlinks, +or "make install-hardlinks" creates hardlinks instead (useful on systems with +a limited number of inodes). This install process uses the file +"busybox.links" (created by make), which contains the list of enabled applets +and the path at which to install them. + +Installing links to busybox is not always necessary. The special applet name +"busybox" (or with any optional suffix, such as "busybox-static") uses the +first argument to determine which applet to behave as, for example +"./busybox cat LICENSE". (Running the busybox applet with no arguments gives +a list of all enabled applets.) The standalone shell can also call busybox +applets without links to busybox under other names in the filesystem. You can +also configure a standalone install capability into the busybox base applet, +and then install such links at runtime with one of "busybox --install" (for +hardlinks) or "busybox --install -s" (for symlinks). + +If you enabled the busybox shared library feature (libbusybox.so) and want +to run tests without installing, set your LD_LIBRARY_PATH accordingly when +running the executable: + + LD_LIBRARY_PATH=`pwd` ./busybox + +Building out-of-tree: +===================== + +By default, the BusyBox build puts its temporary files in the source tree. +Building from a read-only source tree, or building multiple configurations from +the same source directory, requires the ability to put the temporary files +somewhere else. + +To build out of tree, cd to an empty directory and configure busybox from there: + + make KBUILD_SRC=/path/to/source -f /path/to/source/Makefile defconfig + make + make install + +Alternately, use the O=$BUILDPATH option (with an absolute path) during the +configuration step, as in: + + make O=/some/empty/directory allyesconfig + cd /some/empty/directory + make + make CONFIG_PREFIX=. install + +More Information: +================= + +Se also the busybox FAQ, under the questions "How can I get started using +BusyBox" and "How do I build a BusyBox-based system?"

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/busybox-1.37.0/Makefile b/busybox-1.37.0/Makefile new file mode 100644 index 00000000000..1ec8ac3fd04 --- /dev/null +++ b/busybox-1.37.0/Makefile @@ -0,0 +1,1329 @@ +VERSION = 1 +PATCHLEVEL = 37 +SUBLEVEL = 0 +EXTRAVERSION = +NAME = Unnamed + +# *DOCUMENTATION* +# To see a list of typical targets execute "make help" +# More info can be located in ./README +# Comments in this file are targeted only to the developer, do not +# expect to learn how to build the kernel reading this file. + +# Do not print "Entering directory ..." +MAKEFLAGS += --no-print-directory + +# We are using a recursive build, so we need to do a little thinking +# to get the ordering right. +# +# Most importantly: sub-Makefiles should only ever modify files in +# their own directory.

It provides minimalist replacements for most of the + utilities you usually find in bzip2, coreutils, dhcp, diffutils, e2fsprogs, + file, findutils, gawk, grep, inetutils, less, modutils, net-tools, procps, + sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The utilities + in BusyBox often have fewer options than their full-featured cousins; + however, the options that are included provide the expected functionality + and behave very much like their larger counterparts. + + BusyBox has been written with size-optimization and limited resources in + mind, both to produce small binaries and to reduce run-time memory usage. + Busybox is also extremely modular so you can easily include or exclude + commands (or features) at compile time. This makes it easy to customize + embedded systems; to create a working system, just add /dev, /etc, and a + Linux kernel. Busybox (usually together with uClibc) has also been used as + a component of "thin client" desktop systems, live-CD distributions, rescue + disks, installers, and so on. + + BusyBox provides a fairly complete POSIX environment for any small system, + both embedded environments and more full featured systems concerned about + space. Busybox is slowly working towards implementing the full Single Unix + Specification V3 (http://www.opengroup.org/onlinepubs/009695399/), but isn't + there yet (and for size reasons will probably support at most UTF-8 for + internationalization). We are also interested in passing the Linux Test + Project (http://ltp.sourceforge.net). + +---------------- + +Using busybox: + + BusyBox is extremely configurable. This allows you to include only the + components and options you need, thereby reducing binary size. Run 'make + config' or 'make menuconfig' to select the functionality that you wish to + enable. (See 'make help' for more commands.) + + The behavior of busybox is determined by the name it's called under: as + "cp" it behaves like cp, as "sed" it behaves like sed, and so on. Called + as "busybox" it takes the second argument as the name of the applet to + run (I.E. "./busybox ls -l /proc"). + + The "standalone shell" mode is an easy way to try out busybox; this is a + command shell that calls the built-in applets without needing them to be + installed in the path. (Note that this requires /proc to be mounted, if + testing from a boot floppy or in a chroot environment.) + + The build automatically generates a file "busybox.links", which is used by + 'make install' to create symlinks to the BusyBox binary for all compiled in + commands. This uses the CONFIG_PREFIX environment variable to specify + where to install, and installs hardlinks or symlinks depending + on the configuration preferences. (You can also manually run + the install script at "applets/install.sh"). + +---------------- + +Downloading the current source code: + + Source for the latest released version, as well as daily snapshots, can always + be downloaded from + + http://busybox.net/downloads/ + + You can browse the up to the minute source code and change history online. + + http://git.busybox.net/busybox/ + + Anonymous GIT access is available. For instructions, check out: + + http://www.busybox.net/source.html + + For those that are actively contributing and would like to check files in, + see: + + http://busybox.net/developer.html + + The developers also have a bug and patch tracking system + (https://bugs.busybox.net) although posting a bug/patch to the mailing list + is generally a faster way of getting it fixed, and the complete archive of + what happened is the git changelog. + + Note: if you want to compile busybox in a busybox environment you must + select CONFIG_DESKTOP. + +---------------- + +Getting help: + + when you find you need help, you can check out the busybox mailing list + archives at http://busybox.net/lists/busybox/ or even join + the mailing list if you are interested. + +---------------- + +Bugs: + + if you find bugs, please submit a detailed bug report to the busybox mailing + list at busybox@busybox.net. a well-written bug report should include a + transcript of a shell session that demonstrates the bad behavior and enables + anyone else to duplicate the bug on their own machine. the following is such + an example: + + to: busybox@busybox.net + from: diligent@testing.linux.org + subject: /bin/date doesn't work + + package: busybox + version: 1.00 + + when i execute busybox 'date' it produces unexpected results. + with gnu date i get the following output: + + $ date + fri oct 8 14:19:41 mdt 2004 + + but when i use busybox date i get this instead: + + $ date + illegal instruction + + i am using debian unstable, kernel version 2.4.25-vrs2 on a netwinder, + and the latest uclibc from cvs. + + -diligent + + note the careful description and use of examples showing not only what + busybox does, but also a counter example showing what an equivalent app + does (or pointing to the text of a relevant standard). Bug reports lacking + such detail may never be fixed... Thanks for understanding. + +---------------- + +Portability: + + Busybox is developed and tested on Linux 2.4 and 2.6 kernels, compiled + with gcc (the unit-at-a-time optimizations in version 3.4 and later are + worth upgrading to get, but older versions should work), and linked against + uClibc (0.9.27 or greater) or glibc (2.2 or greater). In such an + environment, the full set of busybox features should work, and if + anything doesn't we want to know about it so we can fix it. + + There are many other environments out there, in which busybox may build + and run just fine. We just don't test them. Since busybox consists of a + large number of more or less independent applets, portability is a question + of which features work where. Some busybox applets (such as cat and rm) are + highly portable and likely to work just about anywhere, while others (such as + insmod and losetup) require recent Linux kernels with recent C libraries. + + Earlier versions of Linux and glibc may or may not work, for any given + configuration. Linux 2.2 or earlier should mostly work (there's still + some support code in things like mount.c) but this is no longer regularly + tested, and inherently won't support certain features (such as long files + and --bind mounts). The same is true for glibc 2.0 and 2.1: expect a higher + testing and debugging burden using such old infrastructure. (The busybox + developers are not very interested in supporting these older versions, but + will probably accept small self-contained patches to fix simple problems.) + + Some environments are not recommended. Early versions of uClibc were buggy + and missing many features: upgrade. Linking against libc5 or dietlibc is + not supported and not interesting to the busybox developers. (The first is + obsolete and has no known size or feature advantages over uClibc, the second + has known bugs that its developers have actively refused to fix.) Ancient + Linux kernels (2.0.x and earlier) are similarly uninteresting. + + In theory it's possible to use Busybox under other operating systems (such as + MacOS X, Solaris, Cygwin, or the BSD Fork Du Jour). This generally involves + a different kernel and a different C library at the same time. While it + should be possible to port the majority of the code to work in one of + these environments, don't be surprised if it doesn't work out of the box. If + you're into that sort of thing, start small (selecting just a few applets) + and work your way up. + + In 2005 Shaun Jackman has ported busybox to a combination of newlib + and libgloss, and some of his patches have been integrated. + +Supported hardware: + + BusyBox in general will build on any architecture supported by gcc. We + support both 32 and 64 bit platforms, and both big and little endian + systems. + + Under 2.4 Linux kernels, kernel module loading was implemented in a + platform-specific manner. Busybox's insmod utility has been reported to + work under ARM, CRIS, H8/300, x86, ia64, x86_64, m68k, MIPS, PowerPC, S390, + SH3/4/5, Sparc, and v850e. Anything else probably won't work. + + The module loading mechanism for the 2.6 kernel is much more generic, and + we believe 2.6.x kernel module loading support should work on all + architectures supported by the kernel. + +---------------- + +Please feed suggestions, bug reports, insults, and bribes back to the busybox +mailing list: + + busybox@busybox.net + +and/or maintainer: + + Denys Vlasenko + diff --git a/busybox-1.37.0/TODO b/busybox-1.37.0/TODO new file mode 100644 index 00000000000..6c7415a81f3 --- /dev/null +++ b/busybox-1.37.0/TODO @@ -0,0 +1,256 @@ +Busybox TODO + +Harvest patches from +http://git.openembedded.org/cgit.cgi/openembedded/tree/recipes/busybox/ +https://dev.openwrt.org/browser/trunk/package/busybox/patches/ + + +Stuff that needs to be done.

It needs wider testing. + + Busybox should now be able to replace bzip2, coreutils, e2fsprogs, file, + findutils, gawk, grep, inetutils, less, modutils, net-tools, patch, procps, + sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The resulting + system should be self-hosting (I.E. able to rebuild itself from source + code). This means it would need (at least) binutils, gcc, and make, or + equivalents. + + It would be a good "eating our own dogfood" test if buildroot had the option + of using a "make allyesconfig" busybox instead of the all of the above + packages. Anything that's wrong with the resulting system, we can fix. (It + would be nice to be able to upgrade busybox to be able to replace bash and + diffutils as well, but we're not there yet.) + + One example of an existing system that does this already is Firmware Linux: + http://www.landley.net/code/firmware + + initramfs + Busybox should have a sample initramfs build script.

Either way, there's no guarantee it'll make it to its final + destination before close() gets called, so there's no guarantee that any + error will be reported. + + You need to call fsync() if you care about errors that occur after write(), + but that can have a big performance impact. So make it a config option. +--- +Unify archivers + Lots of archivers have the same general infrastructure. The directory + traversal code should be factored out, and the guts of each archiver could + be some setup code and a series of callbacks for "add this file", + "add this directory", "add this symlink" and so on. + + This could clean up tar and zip, and make it cheaper to add cpio and ar + write support, and possibly even cheaply add things like mkisofs or + mksquashfs someday, if they become relevant. +--- +Text buffer support. + Several existing applets (sort, vi, less...) read + a whole file into memory and act on it. Use open_read_close(). +--- +Memory Allocation + We have a CONFIG_BUFFER mechanism that lets us select whether to do memory + allocation on the stack or the heap. Unfortunately, we're not using it much. + We need to audit our memory allocations and turn a lot of malloc/free calls + into RESERVE_CONFIG_BUFFER/RELEASE_CONFIG_BUFFER. + For a start, see e.g. make EXTRA_CFLAGS=-Wlarger-than-64 + + And while we're at it, many of the CONFIG_FEATURE_CLEAN_UP #ifdefs will be + optimized out by the compiler in the stack allocation case (since there's no + free for an alloca()), and this means that various cleanup loops that just + call free might also be optimized out by the compiler if written right, so + we can yank those #ifdefs too, and generally clean up the code. +--- +FEATURE_CLEAN_UP + This is more an unresolved issue than a to-do item. More thought is needed. + + Normally we rely on exit() to free memory, close files and unmap segments + for us. This makes most calls to free(), close(), and unmap() optional in + busybox applets that don't intend to run for very long, and optional stuff + can be omitted to save size. + + The idea was raised that we could simulate fork/exit with setjmp/longjmp + for _really_ brainless embedded systems, or speed up the standalone shell + by not forking. Doing so would require a reliable FEATURE_CLEAN_UP. + Unfortunately, this isn't as easy as it sounds. + + The problem is, lots of things exit(), sometimes unexpectedly (xmalloc()) + and sometimes reliably (bb_perror_msg_and_die() or show_usage()). This + jumps out of the normal flow control and bypasses any cleanup code we + put at the end of our applets. + + It's possible to add hooks to libbb functions like xmalloc() and xopen() + to add their entries to a linked list, which could be traversed and + freed/closed automatically. (This would need to be able to free just the + entries after a checkpoint to be usable for a forkless standalone shell. + You don't want to free the shell's own resources.) + + Right now, FEATURE_CLEAN_UP is more or less a debugging aid, to make things + like valgrind happy. It's also documentation of _what_ we're trusting + exit() to clean up for us. But new infrastructure to auto-free stuff would + render the existing FEATURE_CLEAN_UP code redundant. + + For right now, exit() handles it just fine. + + +Minor stuff: + watchdog.c could autodetect the timer duration via: + if(!ioctl (fd, WDIOC_GETTIMEOUT, &tmo)) timer_duration = 1 + (tmo / 2); + Unfortunately, that needs linux/watchdog.h and that contains unfiltered + kernel types on some distros, which breaks the build. +--- + use bb_error_msg where appropriate: See + egrep "(printf.*\([[:space:]]*(stderr|2)|[^_]write.*\([[:space:]]*(stderr|2))" +--- + use bb_perror_msg where appropriate: See + egrep "[^_]perror" +--- + possible code duplication ingroup() and is_a_group_member() +--- + Move __get_hz() to a better place and (re)use it in route.c, ash.c +--- + See grep -r strtod + Alot of duplication that wants cleanup. +--- + unify progress_meter. wget, flash_eraseall, pipe_progress, fbsplash, setfiles. +--- + +(TODO list after discussion 11.05.2009) + +* shrink tc/brctl/ip + tc/brctl seem like fairly large things to try and tackle in your timeframe, + and i think people have posted attempts in the past.

Probably you should at least skim through it even if the + default file works as is. + +BCJ filter support + + If you want support for one or more BCJ filters, you need to copy also + linux/lib/xz/xz_dec_bcj.c into your application, and use appropriate + #defines in xz_config.h or in compiler flags.

A config option can be defined multiple times with the same +name, but every definition can have only a single input prompt and the +type must not conflict. + +Menu attributes +--------------- + +A menu entry can have a number of attributes. Not all of them are +applicable everywhere (see syntax). + +- type definition: "bool"/"tristate"/"string"/"hex"/"integer" + Every config option must have a type.

The tristate logic used in the +expressions uses one more state than normal boolean logic to express the +module state. Dependency expressions have the following syntax: + + ::= (1) + '=' (2) + '!=' (3) + '(' ')' (4) + '!' (5) + '||' (6) + '&&' (7) + +Expressions are listed in decreasing order of precedence. + +(1) Convert the symbol into an expression.

Used to override precedence. +(5) Returns the result of (2-/expr/). +(6) Returns the result of min(/expr/, /expr/). +(7) Returns the result of max(/expr/, /expr/). + +An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 +respectively for calculations). A menu entry becomes visible when it's +expression evaluates to 'm' or 'y'. + +There are two type of symbols: constant and nonconstant symbols. +Nonconstant symbols are the most common ones and are defined with the +'config' statement. Nonconstant symbols consist entirely of alphanumeric +characters or underscores. +Constant symbols are only part of expressions. Constant symbols are +always surrounded by single or double quotes. Within the quote any +other character is allowed and the quotes can be escaped using '\'. + +Menu structure +-------------- + +The position of a menu entry in the tree is determined in two ways. First +it can be specified explicitely: + +menu "Network device support" + depends NET + +config NETDEVICES + ... + +endmenu + +All entries within the "menu" ... "endmenu" block become a submenu of +"Network device support". All subentries inherit the dependencies from +the menu entry, e.g. this means the dependency "NET" is added to the +dependency list of the config option NETDEVICES. + +The other way to generate the menu structure is done by analyzing the +dependencies. If a menu entry somehow depends on the previous entry, it +can be made a submenu of it. First the the previous (parent) symbol must +be part of the dependency list and then one of these two condititions +must be true: +- the child entry must become invisible, if the parent is set to 'n' +- the child entry must only be visible, if the parent is visible + +config MODULES + bool "Enable loadable module support" + +config MODVERSIONS + bool "Set version information on all module symbols" + depends MODULES + +comment "module support disabled" + depends !MODULES + +MODVERSIONS directly depends on MODULES, this means it's only visible if +MODULES is different from 'n'. The comment on the other hand is always +visible when MODULES it's visible (the (empty) dependency of MODULES is +also part of the comment dependencies). + + +Kconfig syntax +-------------- + +The configuration file describes a series of menu entries, where every +line starts with a keyword (except help texts). The following keywords +end a menu entry: +- config +- choice/endchoice +- comment +- menu/endmenu +- if/endif +- source +The first four also start the definition of a menu entry. + +config: + + "config" + + +This defines a config symbol and accepts any of above +attributes as options. + +choices: + + "choice" + + + "endchoice" + +This defines a choice group and accepts any of above attributes as +options. A choice can only be of type bool or tristate, while a boolean +choice only allows a single config entry to be selected, a tristate +choice also allows any number of config entries to be set to 'm'. This +can be used if multiple drivers for a single hardware exists and only a +single driver can be compiled/loaded into the kernel, but all drivers +can be compiled as modules. +A choice accepts another option "optional", which allows to set the +choice to 'n' and no entry needs to be selected. + +comment: + + "comment" + + +This defines a comment which is displayed to the user during the +configuration process and is also echoed to the output files.

Baumann, + + 2. Introduction + + This HOWTO will attempt to give hints about how to write a program + which needs to access a serial port. Its principal focus will be on + the Linux implementation and what the meaning of the various library + functions available. + + Someone asked about which of several sequences of operations was + right. There is no absolute right way to accomplish an outcome. The + options available are too numerous. If your sequences produces the + desired results, then that is the right way for you. Another + programmer may select another set of options and get the same results. + His method is right for him. + + Neither of these methods may operate properly with some other + implementation of UNIX. It is strange that many of the concepts which + were implemented in the SYSV version have been dumped. Because UNIX + was developed by AT&T and much code has been generated on those + concepts, the AT&T version should be the standard to which others + should emulate. + + Now the standard is POSIX. + + It was once stated that the popularity of UNIX and C was that they + were created by programmers for programmers. Not by scholars who + insist on purity of style in deference to results and simplicity of + use. Not by committees with people who have diverse personal or + proprietary agenda. Now ANSI and POSIX have strayed from those + original clear and simply concepts. + + 3. Opening + + The various serial devices are opened just as any other file. + Although, the fopen(3) command may be used, the plain open(2) is + preferred. This call returns the file descriptor which is required + for the various commands that configure the interface. + + Open(2) has the format: + + #include + int open(char *path, int flags, [int mode]); + + In addition to the obvious O_RDWR, O_WRONLY and O_RDONLY, two + additional flags are available. These are O_NONBLOCK and O_NOCTTY. + Other flags listed in the open(2) manual page are not applicable to + serial devices. + + Normally, a serial device opens in "blocking" mode. This means that + the open() will not return until the Carrier Detect line from the port + is active, e.g. modem, is active. When opened with the O_NONBLOCK + flag set, the open() will return immediately regardless of the status + of the DCD line. The "blocking" mode also affects the read() call. + + The fcntl(2) command can be used to change the O_NONBLOCK flag anytime + after the device has been opened. + + The device driver and the data passing through it are controlled + according to settings in the struct termios. This structure is + defined in "/usr/include/termios.h". In the Linux tree, further + reference is made to "/usr/include/asm/termbits.h". + In blocking mode, a read(2) will block until data is available or a + signal is received. It is still subject to state of the ICANON flag. + + When the termios.c_lflag ICANON bit is set, input data is collected + into strings until a NL, EOF or EOL character is received. You can + define these in the termios.c_cc[] array. Also, ERASE and KILL + characters will operate on the incoming data before it is delivered to + the user. + + In non-canonical mode, incoming data is quantified by use of the + c_cc[VMIN and c_cc[VTIME] values in termios.c_cc[]. + + Some programmers use the select() call to detect the completion of a + read(). This is not the best way of checking for incoming data. + Select() is part of the SOCKETS scheme and too complex for most + applications. + + A full explanation of the fields of the termios structure is contained + in termios(7) of the Users Manual. A version is included in Part 2 of + this HOWTO document. + + 4. Commands + + Changes to the struct termios are made by retrieving the current + settings, making the desired changes and transmitting the modified + structure back to the kernel. + + The historic means of communicating with the kernel was by use of the + ioctl(fd, COMMAND, arg) system call. Then the purists in the + computer industry decided that this was not genetically consistent. + Their argument was that the argument changed its stripes. Sometimes + it was an int, sometimes it was a pointer to int and other times it + was a pointer to struct termios. Then there were those times it was + empty or NULL. These variations are dependent upon the COMMAND. + + As a alternative, the tc* series of functions were concocted. + + These are: + + int tcgetattr(int filedes, struct termios *termios_p); + int tcsetattr(int filedes, int optional_actions, + const struct termios *termios_p); + + instead of: + + int ioctl(int filedes, int command, + struct termios *termios_p); + + where command is TCGETS or one of TCSETS, TCSETSW or TCSETSF. + + The TCSETS command is comparable to the TCSANOW optional_action for + the tc* version. These direct the kernel to adopt the changes + immediately. Other pairs are: + + command optional_action Meaning + TCSETSW TCSADRAIN Change after all output has drained. + TCSETSF TCSAFLUSH Change after all output has drained + then discard any input characters + not read. + + Since the return code from either the ioctl(2) or the tcsetattr(2) + commands only indicate that the command was processed by the kernel. + These do not indicate whether or not the changes were actually + accomplished. Either of these commands should be followed by a call + to: + + ioctl(fd, TCGETS, &new_termios); + + or: + + tcgetattr(fd, &new_termios); + + A user function which makes changes to the termios structure should + define two struct termios variables. One of these variables should + contain the desired configuration. The other should contain a copy of + the kernels version. Then after the desired configuration has been + sent to the kernel, another call should be made to retrieve the + kernels version. Then the two compared. + + Here is an example of how to add RTS/CTS flow control: + + struct termios my_termios; + struct termios new_termios; + + tcgetattr(fd, &my_termios); + my_termios.c_flag |= CRTSCTS; + tcsetattr(fd, TCSANOW, &my_termios); + tcgetattr(fd, &new_termios); + if (memcmp(my_termios, new_termios, + sizeof(my_termios)) != 0) { + /* do some error handling */ + } + + 5. Changing Baud Rates + + With Linux, the baud rate can be changed using a technique similar to + add/delete RTS/CTS. + + struct termios my_termios; + struct termios new_termios; + + tcgetattr(fd, &my_termios); + my_termios.c_flag &= ~CBAUD; + my_termios.c_flag |= B19200; + tcsetattr(fd, TCSANOW, &my_termios); + tcgetattr(fd, &new_termios); + if (memcmp(my_termios, new_termios, + sizeof(my_termios)) != 0) { + /* do some error handling */ + } + + POSIX adds another method. They define: + + speed_t cfgetispeed(const struct termios *termios_p); + speed_t cfgetospeed(const struct termios *termios_p); + + library calls to extract the current input or output speed from the + struct termios pointed to with *termio_p. This is a variable defined + in the calling process. In practice, the data contained in this + termios, should be obtained by the tcgetattr() call or an ioctl() call + using the TCGETS command. + + The companion library calls are: + + int cfsetispeed(struct termios *termios_p, speed_t speed); + int cfsetospeed(struct termios *termios_p, speed_t speed); + + which are used to change the value of the baud rate in the locally + defined *termios_p. Following either of these calls, either a call to + tcsetattr() or ioctl() with one of TCSETS, TCSETSW or TCSETSF as the + command to transmit the change to the kernel. + + The cf* commands are preferred for portability. Some weird Unices use + a considerably different format of termios. + + Most implementations of Linux use only the input speed for both input + and output. These functions are defined in the application program by + reference to . In reality, they are in + /usr/include/asm/termbits.h. + + 6. Additional Control Calls + + 6.1. Sending a "break". + + int ioctl(fd, TCSBRK, int arg); + int tcsendbreak(fd, int arg); + + Send a break: Here the action differs between the conventional + ioctl() call and the POSIX call. For the conventional call, an arg of + '0' sets the break control line of the UART for 0.25 seconds. For the + POSIX command, the break line is set for arg times 0.1 seconds. + + 6.2. Hardware flow control. + + int ioctl(fd, TCXONC, int action); + int tcflow(fd, int action); + + The action flags are: + + o TCOOFF 0 suspend output + + o TCOON 1 restart output + + o TCIOFF 2 transmit STOP character to suspend input + + o TCION 3 transmit START character to restart input + + 6.3. Flushing I/O buffers. + + int ioctl(fd, TCFLSH, queue_selector); + int tcflush(fd, queue_selector); + + The queue_selector flags are: + + o TCIFLUSH 0 flush any data not yet read from the input buffer + + o TCOFLUSH 1 flush any data written to the output buffer but not + yet transmitted + + o TCIOFLUSH 2 flush both buffers + + 7. Modem control + + The hardware modem control lines can be monitored or modified by the + ioctl(2) system call. A set of comparable tc* calls apparently do not + exist. The form of this call is: + + int ioctl(fd, COMMAND, (int *)flags); + + The COMMANDS and their action are: + + o TIOCMBIS turn on control lines depending upon which bits are set + in flags. + + o TIOCMBIC turn off control lines depending upon which bits are + unset in flags. + o TIOCMGET the appropriate bits are set in flags according to the + current status + + o TIOCMSET the state of the UART is changed according to which bits + are set/unset in 'flags' + + The bit pattern of flags refer to the following control lines: + + o TIOCM_LE Line enable + + o TIOCM_DTR Data Terminal Ready + + o TIOCM_RTS Request to send + + o TIOCM_ST Secondary transmit + + o TIOCM_SR Secondary receive + + o TIOCM_CTS Clear to send + + o TIOCM_CAR Carrier detect + + o TIOCM_RNG Ring + + o TIOCM_DSR Data set ready + + It should be noted that some of these bits are controlled by the modem + and the UART cannot change them but their status can be sensed by + TIOCMGET. Also, most Personal Computers do not provide hardware for + secondary transmit and receive. + + There are also a pair of ioctl() to monitor these lines. They are + undocumented as far as I have learned. The commands are TIOCMIWAIT + and TCIOGICOUNT. They also differ between versions of the Linux + kernel. + + See the lines.c file in my "serial_suite" for an example of how these + can be used see + + 8. Process Groups + + 8.1. Sessions + + 8.2. Process Groups + + Any newly created process inherits the Process Group of its creator. + The Process Group leader has the same PID as PGID. + + 8.3. Controlling Terminal + + There are a series of ioctl(2) and tc*(2) calls which can be used to + monitor or to change the process group to which the device is + attached. + + 8.3.1. Get the foreground group process id. + + If there is no foreground group, a number not representing an existing + process group is returned. On error, a -1 is returned and errno is + set. + + int ioctl(fd, TIOCGPGRP, (pid_t *)pid); + int tcgetpgrp(fd, (pid_t *)pid); + + 8.3.2. Set the foreground process group id of a terminal. + + The fd must be the controlling terminal and be associated with the + session of the calling process. + + int ioctl(fd, TIOCSPGRP, (pid_t *)pid); + int tcsetpgrp(fd, (pid_t *)pid); + + 8.3.3. Get process group id. + + int ioctl(fd, TIOCGPGRP, &(pid_t)pid); + int tcgetpgrp(fd, &(pid_t)pid); + + 9. Lockfiles + + Any process which accesses a serial device should first check for the + existence of lock file for the desired device. If such a lock lock + file exists, this means that the device may be in use by another + process. + + Check my "libdevlocks-x.x.tgz" at + for an example of how these lock + files should be utilized. + + 10.

This may allow you to run your system without the need for +installing any of the NSS configuration files and libraries. + +When used with glibc, the BusyBox 'networking' applets will similarly require +that you install at least some of the glibc NSS stuff (in particular, +/etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*). + +Shameless Plug: As an alternative, one could use a C library such as uClibc. In +addition to making your system significantly smaller, uClibc does not require the +use of any NSS support files or libraries. + +=head1 MAINTAINER + +Denis Vlasenko + +=head1 AUTHORS + +The following people have contributed code to BusyBox whether they know it or +not.

It provides minimalist replacements for most of the utilities +you usually find in GNU coreutils, util-linux, etc. The utilities in BusyBox +generally have fewer options than their full-featured GNU cousins; however, the +options that are included provide the expected functionality and behave very +much like their GNU counterparts. + +BusyBox has been written with size-optimization and limited resources in mind. +It is also extremely modular so you can easily include or exclude commands (or +features) at compile time. This makes it easy to customize your embedded +systems. To create a working system, just add /dev, /etc, and a Linux kernel. +BusyBox provides a fairly complete POSIX environment for any small or embedded +system. + +BusyBox is extremely configurable. This allows you to include only the +components you need, thereby reducing binary size. Run 'make config' or 'make +menuconfig' to select the functionality that you wish to enable. Then run +'make' to compile BusyBox using your configuration. + +After the compile has finished, you should use 'make install' to install +BusyBox. This will install the 'bin/busybox' binary, in the target directory +specified by CONFIG_PREFIX. CONFIG_PREFIX can be set when configuring BusyBox, +or you can specify an alternative location at install time (i.e., with a +command line like 'make CONFIG_PREFIX=/tmp/foo install'). If you enabled +any applet installation scheme (either as symlinks or hardlinks), these will +also be installed in the location pointed to by CONFIG_PREFIX. + +=head1 USAGE + +BusyBox is a multi-call binary. A multi-call binary is an executable program +that performs the same job as more than one utility program. That means there +is just a single BusyBox binary, but that single binary acts like a large +number of utilities. This allows BusyBox to be smaller since all the built-in +utility programs (we call them applets) can share code for many common +operations. + +You can also invoke BusyBox by issuing a command as an argument on the +command line. For example, entering + + /bin/busybox ls + +will also cause BusyBox to behave as 'ls'. + +Of course, adding '/bin/busybox' into every command would be painful. So most +people will invoke BusyBox using links to the BusyBox binary. + +For example, entering + + ln -s /bin/busybox ls + ./ls + +will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled +into BusyBox). Generally speaking, you should never need to make all these +links yourself, as the BusyBox build system will do this for you when you run +the 'make install' command. + +If you invoke BusyBox with no arguments, it will provide you with a list of the +applets that have been compiled into your BusyBox binary. + +=head1 COMMON OPTIONS + +Most BusyBox applets support the B<--help> argument to provide a terse runtime +description of their behavior. If the CONFIG_FEATURE_VERBOSE_USAGE option has +been enabled, more detailed usage information will also be available. + +=head1 COMMANDS + +Currently available applets include: diff --git a/busybox-1.37.0/docs/cgi/cl.html b/busybox-1.37.0/docs/cgi/cl.html new file mode 100644 index 00000000000..4f8faae9fcd --- /dev/null +++ b/busybox-1.37.0/docs/cgi/cl.html @@ -0,0 +1,46 @@ +CGI Command line options

CGI Command line options

+

+ +

Specification

+ +The command line is only used in the case of an ISINDEX query. It is +not used in the case of an HTML form or any as yet undefined query +type. The server should search the query information (the QUERY_STRING environment variable) for a non-encoded += character to determine if the command line is to be used, if it +finds one, the command line is not to be used. This trusts the clients +to encode the = sign in ISINDEX queries, a practice which was +considered safe at the time of the design of this specification.

+ +For example, use the finger script and the ISINDEX interface to look up "httpd". You will see that the script will call itself with /cgi-bin/finger?httpd and will actually execute "finger httpd" on the command line and output the results to you. +

+If the server does find a "=" in the QUERY_STRING, +then the command line will not be used, and no decoding will be +performed. The query then remains intact for processing by an +appropriate FORM submission decoder. +Again, as an example, use this hyperlink to submit "httpd=name" to the finger script. Since this QUERY_STRING +contained an unencoded "=", nothing was decoded, the script didn't know +it was being submitted a valid query, and just gave you the default +finger form. +

+If the server finds that it cannot send the string due to internal +limitations (such as exec() or /bin/sh command line restrictions) the +server should include NO command line information and provide the +non-decoded query information in the environment +variable QUERY_STRING.

+

+

Examples

+ +Examples of the command line usage are much better demonstrated than explained. For these +examples, pay close attention to the script output which says what +argc and argv are.

CGI Environment Variables

+
+ +

+ +In order to pass data about the information request from the server to +the script, the server uses command line arguments as well as +environment variables. These environment variables are set when the +server executes the gateway program.

+ +

+

Specification

+ +

+The following environment variables are not request-specific and are +set for all requests:

+ +

    +
  • SERVER_SOFTWARE

    + + The name and version of the information server software answering + the request (and running the gateway). Format: name/version

    + +

  • SERVER_NAME

    + The server's hostname, DNS alias, or IP address as it would appear + in self-referencing URLs.

    + +

  • GATEWAY_INTERFACE

    + The revision of the CGI specification to which this server + complies. Format: CGI/revision

    + +

+ +
+ +The following environment variables are specific to the request being +fulfilled by the gateway program:

+ +

    +
  • SERVER_PROTOCOL

    + The name and revision of the information protocol this request came + in with. Format: protocol/revision

    + +

  • SERVER_PORT

    + The port number to which the request was sent.

    + +

  • REQUEST_METHOD

    + The method with which the request was made. For HTTP, this is + "GET", "HEAD", "POST", etc.

    + +

  • PATH_INFO

    + The extra path information, as given by the client. In other + words, scripts can be accessed by their virtual pathname, followed + by extra information at the end of this path. The extra + information is sent as PATH_INFO. This information should be + decoded by the server if it comes from a URL before it is passed + to the CGI script.

    + +

  • PATH_TRANSLATED

    + The server provides a translated version of PATH_INFO, which takes + the path and does any virtual-to-physical mapping to it.

    + +

  • SCRIPT_NAME

    + A virtual path to the script being executed, used for + self-referencing URLs.

    + +

  • QUERY_STRING

    + The information which follows the ? in the URL + which referenced this script. This is the query information. It + should not be decoded in any fashion. This variable should always + be set when there is query information, regardless of command line decoding.

    + +

  • REMOTE_HOST

    + The hostname making the request. If the server does not have this + information, it should set REMOTE_ADDR and leave this unset.

    + +

  • REMOTE_ADDR

    + The IP address of the remote host making the request.

    + +

  • AUTH_TYPE

    + If the server supports user authentication, and the script is + protects, this is the protocol-specific authentication method used + to validate the user.

    + +

  • REMOTE_USER

    + If the server supports user authentication, and the script is + protected, this is the username they have authenticated as.

    +

  • REMOTE_IDENT

    + If the HTTP server supports RFC 931 identification, then this + variable will be set to the remote user name retrieved from the + server. Usage of this variable should be limited to logging only. +

    + +

  • CONTENT_TYPE

    + For queries which have attached information, such as HTTP POST and + PUT, this is the content type of the data.

    + +

  • CONTENT_LENGTH

    + The length of the said content as given by the client.

    + +

+ + +
 + +In addition to these, the header lines received from the client, if +any, are placed into the environment with the prefix HTTP_ followed by +the header name. Any - characters in the header name are changed to _ +characters. The server may exclude any headers which it has already +processed, such as Authorization, Content-type, and Content-length. If +necessary, the server may choose to exclude any or all of these +headers if including them would exceed any system environment +limits.

+ +An example of this is the HTTP_ACCEPT variable which was defined in +CGI/1.0. Another example is the header User-Agent.

+ +

    +
  • HTTP_ACCEPT

    + The MIME types which the client will accept, as given by HTTP + headers. Other protocols may need to get this information from + elsewhere. Each item in this list should be separated by commas as + per the HTTP spec.

    + + Format: type/subtype, type/subtype

    + + +

  • HTTP_USER_AGENT

    + + The browser the client is using to send the request. General +format: software/version library/version.

CGI Script Input

+
+ +

Specification

+ +For requests which have information attached after the header, such as +HTTP POST or PUT, the information will be sent to the script on stdin. +

+ +The server will send CONTENT_LENGTH bytes on +this file descriptor. Remember that it will give the CONTENT_TYPE of the data as well. The server is +in no way obligated to send end-of-file after the script reads +CONTENT_LENGTH bytes.

+

+

Example

+ +Let's take a form with METHOD="POST" as an example. Let's say the form +results are 7 bytes encoded, and look like a=b&b=c. +

+ +In this case, the server will set CONTENT_LENGTH to 7 and CONTENT_TYPE +to application/x-www-form-urlencoded. The first byte on the script's +standard input will be "a", followed by the rest of the encoded string.

CGI Script Output

+
+ +

Script output

+ +The script sends its output to stdout. This output can either be a +document generated by the script, or instructions to the server for +retrieving the desired output.

+

+ +

Script naming conventions

+ +Normally, scripts produce output which is interpreted and sent back to +the client. An advantage of this is that the scripts do not need to +send a full HTTP/1.0 header for every request.

+ +Some scripts may want to avoid the extra overhead of the server +parsing their output, and talk directly to the client. In order to +distinguish these scripts from the other scripts, CGI requires that +the script name begins with nph- if a script does not want the server +to parse its header. In this case, it is the script's responsibility +to return a valid HTTP/1.0 (or HTTP/0.9) response to the client.

+ +

+

Parsed headers

+ +The output of scripts begins with a small header. This header consists +of text lines, in the same format as an +HTTP header, terminated by a blank line (a line with only a +linefeed or CR/LF).

+ +Any headers which are not server directives are sent directly back to +the client. Currently, this specification defines three server +directives:

+ +

    +
  • Content-type

    + + This is the MIME type of the document you are returning.

    + +

  • Location

    + + This is used to specify to the server that you are returning a + reference to a document rather than an actual document.

    + + If the argument to this is a URL, the server will issue a redirect + to the client.

    + + If the argument to this is a virtual path, the server will + retrieve the document specified as if the client had requested + that document originally. ? directives will work in here, but # + directives must be redirected back to the client.

    + + +

  • Status

    + + This is used to give the server an HTTP/1.0 status +line to send to the client. The format is nnn xxxxx, +where nnn is the 3-digit status code, and +xxxxx is the reason string, such as "Forbidden".

    + +

+ +
+

Examples

+ +Let's say I have a fromgratz to HTML converter. When my converter is +finished with its work, it will output the following on stdout (note +that the lines beginning and ending with --- are just for illustration +and would not be output):

+ +

--- start of output ---
+Content-type: text/html
+
+--- end of output ---
+
+ +Note the blank line after Content-type.

+ +Now, let's say I have a script which, in certain instances, wants to +return the document /path/doc.txt from this server just +as if the user had actually requested +http://server:port/path/doc.txt to begin with. In this +case, the script would output:

+

--- start of output ---
+Location: /path/doc.txt
+
+--- end of output ---
+
+ +The server would then perform the request and send it to the client. +

+ +Let's say that I have a script which wants to reference our gopher +server. In this case, if the script wanted to refer the user to +gopher://gopher.ncsa.uiuc.edu/, it would output:

+ +

--- start of output ---
+Location: gopher://gopher.ncsa.uiuc.edu/
+
+--- end of output ---
+
+ +Finally, I have a script which wants to talk to the client directly. +In this case, if the script is referenced with SERVER_PROTOCOL of HTTP/1.0, +the script would output the following HTTP/1.0 response:

+ +

--- start of output ---
+HTTP/1.0 200 OK
+Server: NCSA/1.0a6
+Content-type: text/plain
+
+This is a plaintext document generated on the fly just for you.

Great, wonderful, glad you want to +help. However, before you dive in, headlong and hotfoot, there are some things +you need to do: + + +Checkout the Latest Code +~~~~~~~~~~~~~~~~~~~~~~~~ + +This is a necessary first step. Please do not try to work with the last +released version, as there is a good chance that somebody has already fixed +the bug you found. Somebody might have even added the feature you had in mind. +Don't make your work obsolete before you start! + +For information on how to check out Busybox development tree, please look at the +following links: + + http://busybox.net/source.html + + +Read the Mailing List +~~~~~~~~~~~~~~~~~~~~~ + +No one is required to read the entire archives of the mailing list, but you +should at least read up on what people have been talking about lately. If +you've recently discovered a problem, chances are somebody else has too. If +you're the first to discover a problem, post a message and let the rest of us +know. + +Archives can be found here: + + http://busybox.net/lists/busybox/ + +If you have a serious interest in Busybox, i.e., you are using it day-to-day or +as part of an embedded project, it would be a good idea to join the mailing +list. + +A web-based sign-up form can be found here: + + http://busybox.net/mailman/listinfo/busybox + + +Coordinate with the Applet Maintainer +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Some (not all) of the applets in Busybox are "owned" by a maintainer who has +put significant effort into it and is probably more familiar with it than +others. To find the maintainer of an applet, look at the top of the .c file +for a name following the word 'Copyright' or 'Written by' or 'Maintainer'. + +Before plunging ahead, it's a good idea to send a message to the mailing list +that says: "Hey, I was thinking about adding the 'transmogrify' feature to the +'foo' applet. Would this be useful? Is anyone else working on it?" You might +want to CC the maintainer (if any) with your question. + + + +Areas Where You Can Help +------------------------ + +Busybox can always use improvement! If you're looking for ways to help, there +are a variety of areas where you could help. + + +What Busybox Doesn't Need +~~~~~~~~~~~~~~~~~~~~~~~~~ + +Before listing the areas where you _can_ help, it's worthwhile to mention the +areas where you shouldn't bother. While Busybox strives to be the "Swiss Army +Knife" of embedded Linux, there are some applets that will not be accepted: + + - Any filesystem manipulation tools: Busybox is filesystem independent and + we do not want to start adding mkfs/fsck tools for every (or any) + filesystem under the sun. (fsck_minix.c and mkfs_minix.c are living on + borrowed time.) There are far too many of these tools out there. Use + the upstream version. Rationale: bugs in these tools can destroy + vast amounts of data. Keeping up with filesystem format development + is impractical (especially in the area of keeping fsck tool safe + and up-to-date). + + - Any disk, device, or media-specific tools: Use the -utils or -tools package + that was designed for your device; don't try to shoehorn them into Busybox. + + - Any architecture specific tools: Busybox is (or should be) architecture + independent. Do not send us tools that cannot be used across multiple + platforms / arches. + + +Bug Reporting +~~~~~~~~~~~~~ + +If you find bugs, please submit a detailed bug report to the busybox mailing +list at busybox@busybox.net. A well-written bug report should include a +transcript of a shell session that demonstrates the bad behavior and enables +anyone else to duplicate the bug on their own machine. The following is such +an example: + + To: busybox@busybox.net + From: diligent@testing.linux.org + Subject: /bin/date doesn't work + + Package: busybox + Version: 1.00 + + When I execute Busybox 'date' it produces unexpected results. + With GNU date I get the following output: + + $ date + Wed Mar 21 14:19:41 MST 2001 + + But when I use BusyBox date I get this instead: + + $ date + Illegal instruction + + I am using Debian unstable, kernel version 2.4.19-rmk1 on an Netwinder, + and the latest uClibc from CVS. + + -Diligent + +Note the careful description and use of examples showing not only what BusyBox +does, but also a counter example showing what an equivalent GNU app does. Bug +reports lacking such detail may never be fixed... Thanks for understanding. + + + +Write Documentation +~~~~~~~~~~~~~~~~~~~ + +Chances are, documentation in Busybox is either missing or needs improvement. +Either way, help is welcome. + +Work is being done to automatically generate documentation from sources, +especially from the usage.h file. If you want to correct the documentation, +please make changes to the pre-generation parts, rather than the generated +documentation. [More to come on this later...] + +It is preferred that modifications to documentation be submitted in patch +format (more on this below), but we're a little more lenient when it comes to +docs. You could, for example, just say "after the listing of the mount +options, the following example would be helpful..." + + +Consult Existing Sources +~~~~~~~~~~~~~~~~~~~~~~~~ + +For a quick listing of "needs work" spots in the sources, cd into the Busybox +directory and run the following: + + for i in TODO FIXME XXX; do find -name '*.[ch]'|xargs grep $i; done + +This will show all of the trouble spots or 'questionable' code. Pick a spot, +any spot, these are all invitations for you to contribute. + + +Add a New Applet +~~~~~~~~~~~~~~~~ + +If you want to add a new applet to Busybox, we'd love to see it. However, +before you write any code, please ask beforehand on the mailing list something +like "Do you think applet 'foo' would be useful in Busybox?" or "Would you +guys accept applet 'foo' into Busybox if I were to write it?" If the answer is +"no" by the folks on the mailing list, then you've saved yourself some time. +Conversely, you could get some positive responses from folks who might be +interested in helping you implement it, or can recommend the best approach. +Perhaps most importantly, this is your way of calling "dibs" on something and +avoiding duplication of effort. + +Also, before you write a line of code, please read the 'new-applet-HOWTO.txt' +file in the docs/ directory. + + +Janitorial Work +~~~~~~~~~~~~~~~ + +These are dirty jobs, but somebody's gotta do 'em. + + - Security audits: + http://www.securityfocus.com/popups/forums/secprog/intro.shtml + + - Synthetic code removal: http://www.perl.com/pub/2000/06/commify.html - This + is very Perl-specific, but the advice given in here applies equally well to + C. + + - C library function use audits: Verifying that functions are being used + properly (called with the right args), replacing unsafe library functions + with safer versions, making sure return codes are being checked, etc. + + - Where appropriate, replace preprocessor defined macros and values with + compile-time equivalents. + + - Style guide compliance.

Just make +sure you're in the busybox/ directory and type: + + git diff -b -w > mychanges.patch + +You can send the resulting .patch file to the mailing list with a description +of what it does. (But not before you test it! See the next section for some +guidelines.) It is preferred that patches be sent as attachments, but it is +not required. + +Also, feel free to help test other people's patches and reply to them with +comments. You can apply a patch by saving it into your busybox/ directory and +typing: + + patch -p1 < mychanges.patch + +Then you can recompile, see if it runs, test if it works as advertised, and +post your findings to the mailing list. + +NOTE: Please do not include extraneous or irrelevant changes in your patches. +Please do not try to "bundle" two patches together into one. Make single, +discreet changes on a per-patch basis. Sometimes you need to make a patch that +touches code in many places, but these kind of patches are rare and should be +coordinated with a maintainer. + + +Testing Guidelines +~~~~~~~~~~~~~~~~~~ + +It's considered good form to test your new feature before you submit a patch +to the mailing list, and especially before you push a change to Git. Here +are some guidelines on how to test your changes. + + - Always test Busybox applets against GNU counterparts and make sure the + behavior / output is identical between the two. + + - Try several different permutations and combinations of the features you're + adding (i.e., different combinations of command-line switches) and make sure + they all work; make sure one feature does not interfere with another. + + - Make sure you test compiling against the source both with the feature + turned on and turned off in Config.h and make sure Busybox compiles cleanly + both ways. + + - Run the multibuild.pl script in the tests directory and make sure + everything checks out OK. (Do this from within the busybox/ directory by + typing: 'tests/multibuild.pl'.) + + +Making Sure Your Patch Doesn't Get Lost +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you don't want your patch to be lost or forgotten, send it to the busybox +mailing list with a subject line something like this: + + [PATCH] - Adds "transmogrify" feature to "foo" + +In the body, you should have a pseudo-header that looks like the following: + + Package: busybox + Version: v1.01pre (or whatever the current version is) + Severity: wishlist + +The remainder of the body should read along these lines: + + This patch adds the "transmogrify" feature to the "foo" applet. I have + tested this on [arch] system(s) and it works. I have tested it against the + GNU counterparts and the outputs are identical. I have run the scripts in + the 'tests' directory and nothing breaks. + + + +Improving Your Chances of Patch Acceptance +------------------------------------------ + +Even after you send a brilliant patch to the mailing list, sometimes it can go +unnoticed, un-replied-to, and sometimes (sigh) even lost. This is an +unfortunate fact of life, but there are steps you can take to help your patch +get noticed and convince a maintainer that it should be added: + + +Be Succinct +~~~~~~~~~~~ + +A patch that includes small, isolated, obvious changes is more likely to be +accepted than a patch that touches code in lots of different places or makes +sweeping, dubious changes. + + +Back It Up +~~~~~~~~~~ + +Hard facts on why your patch is better than the existing code will go a long +way toward convincing maintainers that your patch should be included. +Specifically, patches are more likely to be accepted if they are provably more +correct, smaller, faster, simpler, or more maintainable than the existing +code. + +Conversely, any patch that is supported with nothing more than "I think this +would be cool" or "this patch is good because I say it is and I've got a Phd +in Computer Science" will likely be ignored. + + +Follow The Style Guide +~~~~~~~~~~~~~~~~~~~~~~ + +It's considered good form to abide by the established coding style used in a +project; Busybox is no exception. We have gone so far as to delineate the +"elements of Busybox style" in the file docs/style-guide.txt. Please follow +them. + + +Work With Someone Else +~~~~~~~~~~~~~~~~~~~~~~ + +Working on a patch in isolation is less effective than working with someone +else for a variety of reasons. If another Busybox user is interested in what +you're doing, then it's two (or more) voices instead of one that can petition +for inclusion of the patch. You'll also have more people that can test your +changes, or even offer suggestions on better approaches you could take. + +Getting other folks interested follows as a natural course if you've received +responses from queries to applet maintainer or positive responses from folks +on the mailing list. + +We've made strident efforts to put a useful "collaboration" infrastructure in +place in the form of mailing lists, the bug tracking system, and Git. Please +use these resources. + + +Send Patches to the Bug Tracking System +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This was mentioned above in the "Making Sure Your Patch Doesn't Get Lost" +section, but it is worth mentioning again. A patch sent to the mailing list +might be unnoticed and forgotten. A patch sent to the bug tracking system will +be stored and closely connected to the bug it fixes. + + +Be Polite +~~~~~~~~~ + +The old saying "You'll catch more flies with honey than you will with vinegar" +applies when submitting patches to the mailing list for approval. The way you +present your patch is sometimes just as important as the actual patch itself +(if not more so). Being rude to the maintainers is not an effective way to +convince them that your patch should be included; it will likely have the +opposite effect. + + + +Pushing Changes to Git +---------------------- + +If you submit several patches that demonstrate that you are a skilled and wise +coder, you may be invited to become a committer, thus enabling you to push +changes directly to Git. This is nice because you don't have to wait for +someone else to push your change for you, you can just do it yourself. + +But note that this is a privilege that comes with some responsibilities. You +should test your changes before you push them. You should also talk to an +applet maintainer before you make any kind of sweeping changes to somebody +else's code. Big changes should still go to the mailing list first. Remember, +being wise, polite, and discreet is more important than being clever. + +For more information on Git push access, see: + + http://busybox.net/developer.html + + +When To Push +~~~~~~~~~~~~ + +Generally, you should feel free to push a change if: + + - Your changes are small and don't touch many files + - You are fixing a bug + - Somebody has told you that it's okay + - It's obviously the Right Thing + +The more of the above are true, the better it is to just push a change +directly to Git. + + +When Not To Push +~~~~~~~~~~~~~~~~ + +Even if you have push access, you should probably still post a patch to the +mailing list if: + + - Your changes are broad and touch many different files + - You are adding a feature + - Your changes are speculative or experimental (i.e., trying a new algorithm) + - You are not the maintainer and your changes make the maintainer cringe + +The more of the above are true, the better it is to post a patch to the +mailing list instead of pushing. + + + +Final Words +----------- + +If all of this seems complicated, don't panic, it's really not that tough. If +you're having difficulty following some of the steps outlined in this +document don't worry, the folks on the Busybox mailing list are a fairly +good-natured bunch and will work with you to help get your patches into shape +or help you make contributions. diff --git a/busybox-1.37.0/docs/ctty.htm b/busybox-1.37.0/docs/ctty.htm new file mode 100644 index 00000000000..3cb2dd2bdba --- /dev/null +++ b/busybox-1.37.0/docs/ctty.htm @@ -0,0 +1,479 @@ + + + + The Linux kernel: Processes + + +

10. Processes

+ +

Before looking at the Linux implementation, first a general Unix +description of threads, processes, process groups and sessions. +

+(See also General Terminal Interface) +

A session contains a number of process groups, and a process group +contains a number of processes, and a process contains a number +of threads. +

A session can have a controlling tty. +At most one process group in a session can be a foreground process group. +An interrupt character typed on a tty ("Teletype", i.e., terminal) +causes a signal to be sent to all members of the foreground process group +in the session (if any) that has that tty as controlling tty. +

All these objects have numbers, and we have thread IDs, process IDs, +process group IDs and session IDs. +

+

10.1 Processes +

+ +

+

Creation

+ +

A new process is traditionally started using the fork() +system call: +

+
pid_t p;
+
+p = fork();
+if (p == (pid_t) -1)
+        /* ERROR */
+else if (p == 0)
+        /* CHILD */
+else
+        /* PARENT */
+
+
+

This creates a child as a duplicate of its parent. +Parent and child are identical in almost all respects. +In the code they are distinguished by the fact that the parent +learns the process ID of its child, while fork() +returns 0 in the child. (It can find the process ID of its +parent using the getppid() system call.) +

+

Termination

+ +

Normal termination is when the process does +

+
exit(n);
+
+
+ +or +
+
return n;
+
+
+ +from its main() procedure. It returns the single byte n +to its parent. +

Abnormal termination is usually caused by a signal. +

+

Collecting the exit code. Zombies

+ +

The parent does +

+
pid_t p;
+int status;
+
+p = wait(&status);
+
+
+ +and collects two bytes: +

+

+ + + +

A process that has terminated but has not yet been waited for +is a zombie. It need only store these two bytes: +exit code and reason for termination. +

On the other hand, if the parent dies first, init (process 1) +inherits the child and becomes its parent. +

+

Signals

+ +

+

Stopping

+ +

Some signals cause a process to stop: +SIGSTOP (stop!), +SIGTSTP (stop from tty: probably ^Z was typed), +SIGTTIN (tty input asked by background process), +SIGTTOU (tty output sent by background process, and this was +disallowed by stty tostop). +

Apart from ^Z there also is ^Y. The former stops the process +when it is typed, the latter stops it when it is read. +

Signals generated by typing the corresponding character on some tty +are sent to all processes that are in the foreground process group +of the session that has that tty as controlling tty. (Details below.) +

If a process is being traced, every signal will stop it. +

+

Continuing

+ +

SIGCONT: continue a stopped process. +

+

Terminating

+ +

SIGKILL (die! now!), +SIGTERM (please, go away), +SIGHUP (modem hangup), +SIGINT (^C), +SIGQUIT (^\), etc. +Many signals have as default action to kill the target. +(Sometimes with an additional core dump, when such is +allowed by rlimit.) +The signals SIGCHLD and SIGWINCH +are ignored by default. +All except SIGKILL and SIGSTOP can be +caught or ignored or blocked. +For details, see signal(7). +

+

10.2 Process groups +

+ +

Every process is member of a unique process group, +identified by its process group ID. +(When the process is created, it becomes a member of the process group +of its parent.) +By convention, the process group ID of a process group +equals the process ID of the first member of the process group, +called the process group leader. +A process finds the ID of its process group using the system call +getpgrp(), or, equivalently, getpgid(0). +One finds the process group ID of process p using +getpgid(p). +

One may use the command ps j to see PPID (parent process ID), +PID (process ID), PGID (process group ID) and SID (session ID) +of processes. With a shell that does not know about job control, +like ash, each of its children will be in the same session +and have the same process group as the shell. With a shell that knows +about job control, like bash, the processes of one pipeline, like +

+
% cat paper | ideal | pic | tbl | eqn | ditroff > out
+
+
+ +form a single process group. +

+

Creation

+ +

A process pid is put into the process group pgid by +

+
setpgid(pid, pgid);
+
+
+ +If pgid == pid or pgid == 0 then this creates +a new process group with process group leader pid. +Otherwise, this puts pid into the already existing +process group pgid. +A zero pid refers to the current process. +The call setpgrp() is equivalent to setpgid(0,0). +

+

Restrictions on setpgid()

+ +

The calling process must be pid itself, or its parent, +and the parent can only do this before pid has done +exec(), and only when both belong to the same session. +It is an error if process pid is a session leader +(and this call would change its pgid). +

+

Typical sequence

+ +

+

+
p = fork();
+if (p == (pid_t) -1) {
+        /* ERROR */
+} else if (p == 0) {    /* CHILD */
+        setpgid(0, pgid);
+        ...
+} else {                /* PARENT */
+        setpgid(p, pgid);
+        ...
+}
+
+
+ +This ensures that regardless of whether parent or child is scheduled +first, the process group setting is as expected by both. +

+

Signalling and waiting

+ +

One can signal all members of a process group: +

+
killpg(pgrp, sig);
+
+
+

One can wait for children in ones own process group: +

+
waitpid(0, &status, ...);
+
+
+ +or in a specified process group: +
+
waitpid(-pgrp, &status, ...);
+
+
+

+

Foreground process group

+ +

Among the process groups in a session at most one can be +the foreground process group of that session. +The tty input and tty signals (signals generated by ^C, ^Z, etc.) +go to processes in this foreground process group. +

A process can determine the foreground process group in its session +using tcgetpgrp(fd), where fd refers to its +controlling tty. If there is none, this returns a random value +larger than 1 that is not a process group ID. +

A process can set the foreground process group in its session +using tcsetpgrp(fd,pgrp), where fd refers to its +controlling tty, and pgrp is a process group in +its session, and this session still is associated to the controlling +tty of the calling process. +

How does one get fd? By definition, /dev/tty +refers to the controlling tty, entirely independent of redirects +of standard input and output. (There is also the function +ctermid() to get the name of the controlling terminal. +On a POSIX standard system it will return /dev/tty.) +Opening the name of the +controlling tty gives a file descriptor fd. +

+

Background process groups

+ +

All process groups in a session that are not foreground +process group are background process groups. +Since the user at the keyboard is interacting with foreground +processes, background processes should stay away from it. +When a background process reads from the terminal it gets +a SIGTTIN signal. Normally, that will stop it, the job control shell +notices and tells the user, who can say fg to continue +this background process as a foreground process, and then this +process can read from the terminal. But if the background process +ignores or blocks the SIGTTIN signal, or if its process group +is orphaned (see below), then the read() returns an EIO error, +and no signal is sent. (Indeed, the idea is to tell the process +that reading from the terminal is not allowed right now. +If it wouldn't see the signal, then it will see the error return.) +

When a background process writes to the terminal, it may get +a SIGTTOU signal. May: namely, when the flag that this must happen +is set (it is off by default). One can set the flag by +

+
% stty tostop
+
+
+ +and clear it again by +
+
% stty -tostop
+
+
+ +and inspect it by +
+
% stty -a
+
+
+ +Again, if TOSTOP is set but the background process ignores or blocks +the SIGTTOU signal, or if its process group is orphaned (see below), +then the write() returns an EIO error, and no signal is sent. +[vda: correction. SUS says that if SIGTTOU is blocked/ignored, write succeeds. ] +

+

Orphaned process groups

+ +

The process group leader is the first member of the process group. +It may terminate before the others, and then the process group is +without leader. +

A process group is called orphaned when the +parent of every member is either in the process group +or outside the session. +In particular, the process group of the session leader +is always orphaned. +

If termination of a process causes a process group to become +orphaned, and some member is stopped, then all are sent first SIGHUP +and then SIGCONT. +

The idea is that perhaps the parent of the process group leader +is a job control shell. (In the same session but a different +process group.) As long as this parent is alive, it can +handle the stopping and starting of members in the process group. +When it dies, there may be nobody to continue stopped processes. +Therefore, these stopped processes are sent SIGHUP, so that they +die unless they catch or ignore it, and then SIGCONT to continue them. +

Note that the process group of the session leader is already +orphaned, so no signals are sent when the session leader dies. +

Note also that a process group can become orphaned in two ways +by termination of a process: either it was a parent and not itself +in the process group, or it was the last element of the process group +with a parent outside but in the same session. +Furthermore, that a process group can become orphaned +other than by termination of a process, namely when some +member is moved to a different process group. +

+

10.3 Sessions +

+ +

Every process group is in a unique session. +(When the process is created, it becomes a member of the session +of its parent.) +By convention, the session ID of a session +equals the process ID of the first member of the session, +called the session leader. +A process finds the ID of its session using the system call +getsid(). +

Every session may have a controlling tty, +that then also is called the controlling tty of each of +its member processes. +A file descriptor for the controlling tty is obtained by +opening /dev/tty. (And when that fails, there was no +controlling tty.) Given a file descriptor for the controlling tty, +one may obtain the SID using tcgetsid(fd). +

A session is often set up by a login process. The terminal +on which one is logged in then becomes the controlling tty +of the session. All processes that are descendants of the +login process will in general be members of the session. +

+

Creation

+ +

A new session is created by +

+
pid = setsid();
+
+
+ +This is allowed only when the current process is not a process group leader. +In order to be sure of that we fork first: +
+
p = fork();
+if (p) exit(0);
+pid = setsid();
+
+
+ +The result is that the current process (with process ID pid) +becomes session leader of a new session with session ID pid. +Moreover, it becomes process group leader of a new process group. +Both session and process group contain only the single process pid. +Furthermore, this process has no controlling tty. +

The restriction that the current process must not be a process group leader +is needed: otherwise its PID serves as PGID of some existing process group +and cannot be used as the PGID of a new process group. +

+

Getting a controlling tty

+ +

How does one get a controlling terminal? Nobody knows, +this is a great mystery. +

The System V approach is that the first tty opened by the process +becomes its controlling tty. +

The BSD approach is that one has to explicitly call +

+
ioctl(fd, TIOCSCTTY, 0/1);
+
+
+ +to get a controlling tty. +

Linux tries to be compatible with both, as always, and this +results in a very obscure complex of conditions. Roughly: +

The TIOCSCTTY ioctl will give us a controlling tty, +provided that (i) the current process is a session leader, +and (ii) it does not yet have a controlling tty, and +(iii) maybe the tty should not already control some other session; +if it does it is an error if we aren't root, or we steal the tty +if we are all-powerful. +[vda: correction: third parameter controls this: if 1, we steal tty from +any such session, if 0, we don't steal] +

Opening some terminal will give us a controlling tty, +provided that (i) the current process is a session leader, and +(ii) it does not yet have a controlling tty, and +(iii) the tty does not already control some other session, and +(iv) the open did not have the O_NOCTTY flag, and +(v) the tty is not the foreground VT, and +(vi) the tty is not the console, and +(vii) maybe the tty should not be master or slave pty. +

+

Getting rid of a controlling tty

+ +

If a process wants to continue as a daemon, it must detach itself +from its controlling tty. Above we saw that setsid() +will remove the controlling tty. Also the ioctl TIOCNOTTY does this. +Moreover, in order not to get a controlling tty again as soon as it +opens a tty, the process has to fork once more, to assure that it +is not a session leader. Typical code fragment: +

+

        if ((fork()) != 0)
+                exit(0);
+        setsid();
+        if ((fork()) != 0)
+                exit(0);
+
+

See also daemon(3). +

+

Disconnect

+ +

If the terminal goes away by modem hangup, and the line was not local, +then a SIGHUP is sent to the session leader. +Any further reads from the gone terminal return EOF. +(Or possibly -1 with errno set to EIO.) +

If the terminal is the slave side of a pseudotty, and the master side +is closed (for the last time), then a SIGHUP is sent to the foreground +process group of the slave side. +

When the session leader dies, a SIGHUP is sent to all processes +in the foreground process group. Moreover, the terminal stops being +the controlling terminal of this session (so that it can become +the controlling terminal of another session). +

Thus, if the terminal goes away and the session leader is +a job control shell, then it can handle things for its descendants, +e.g. by sending them again a SIGHUP. +If on the other hand the session leader is an innocent process +that does not catch SIGHUP, it will die, and all foreground processes +get a SIGHUP. +

+

10.4 Threads +

+ +

A process can have several threads. New threads (with the same PID +as the parent thread) are started using the clone system +call using the CLONE_THREAD flag. Threads are distinguished +by a thread ID (TID). An ordinary process has a single thread +with TID equal to PID. The system call gettid() returns the +TID. The system call tkill() sends a signal to a single thread. +

Example: a process with two threads. Both only print PID and TID and exit. +(Linux 2.4.19 or later.) +

% cat << EOF > gettid-demo.c
+#include <unistd.h>
+#include <sys/types.h>
+#define CLONE_SIGHAND   0x00000800
+#define CLONE_THREAD    0x00010000
+#include <linux/unistd.h>
+#include <errno.h>
+_syscall0(pid_t,gettid)
+
+int thread(void *p) {
+        printf("thread: %d %d\n", gettid(), getpid());
+}
+
+main() {
+        unsigned char stack[4096];
+        int i;
+
+        i = clone(thread, stack+2048, CLONE_THREAD | CLONE_SIGHAND, NULL);
+        if (i == -1)
+                perror("clone");
+        else
+                printf("clone returns %d\n", i);
+        printf("parent: %d %d\n", gettid(), getpid());
+}
+EOF

+ The WWW Common Gateway Interface +
+ Version 1.1 +

+ + + +

+ + Abstract + +

+

+ The Common Gateway Interface (CGI) is a simple interface for running + external programs, software or gateways under an information server + in a platform-independent manner. Currently, the supported information + servers are HTTP servers. +

+

+ The interface has been in use by the World-Wide Web since 1993. This + specification defines the + "current practice" parameters of the + 'CGI/1.1' interface developed and documented at the U.S. National + Centre for Supercomputing Applications [NCSA-CGI]. + This document also defines the use of the CGI/1.1 interface + on the Unix and AmigaDOS(tm) systems. +

+

+ Discussion of this draft occurs on the CGI-WG mailing list; see the + project Web page at + <URL:http://CGI-Spec.Golux.Com/> + for details on the mailing list and the status of the project. +

+ + 1. Introduction + +

+ +

+ + 1.1. Purpose + +

+

+ Together the HTTP [3,8] server + and the CGI script are responsible + for servicing a client + request by sending back responses. The client + request comprises a Universal Resource Identifier (URI) + [1], a + request method, and various ancillary + information about the request + provided by the transport mechanism. +

+

+ The CGI defines the abstract parameters, known as + metavariables, + which describe the client's + request. Together with a + concrete programmer interface this specifies a platform-independent + interface between the script and the HTTP server. +

+ +

+ + 1.2. Requirements + +

+

+ This specification uses the same words as RFC 1123 + [5] to define the + significance of each particular requirement. These are: +

+

+
+
MUST +
+
+

+ This word or the adjective 'required' means that the item is an + absolute requirement of the specification. +

+
+
SHOULD +
+
+

+ This word or the adjective 'recommended' means that there may + exist valid reasons in particular circumstances to ignore this + item, but the full implications should be understood and the case + carefully weighed before choosing a different course. +

+
+
MAY +
+
+

+ This word or the adjective 'optional' means that this item is + truly optional. One vendor may choose to include the item because + a particular marketplace requires it or because it enhances the + product, for example; another vendor may omit the same item. +

+
+
+

+ An implementation is not compliant if it fails to satisfy one or more + of the 'must' requirements for the protocols it implements. An + implementation that satisfies all of the 'must' and all of the + 'should' requirements for its features is said to be 'unconditionally + compliant'; one that satisfies all of the 'must' requirements but not + all of the 'should' requirements for its features is said to be + 'conditionally compliant.' +

+ +

+ + 1.3. Specifications + +

+

+ Not all of the functions and features of the CGI are defined in the + main part of this specification. The following phrases are used to + describe the features which are not specified: +

+
+
system defined +
+
+

+ The feature may differ between systems, but must be the same for + different implementations using the same system. A system will + usually identify a class of operating-systems. Some systems are + defined in + section 10 of this document. + New systems may be defined + by new specifications without revision of this document. +

+
+
implementation defined +
+
+

+ The behaviour of the feature may vary from implementation to + implementation, but a particular implementation must document its + behaviour. +

+
+
+ +

+ + 1.4. Terminology + +

+

+ This specification uses many terms defined in the HTTP/1.1 + specification [8]; however, the following terms are + used here in a + sense which may not accord with their definitions in that document, + or with their common meaning. +

+ +
+
metavariable +
+
+

+ A named parameter that carries information from the server to the + script. It is not necessarily a variable in the operating-system's + environment, although that is the most common implementation. +

+
+ +
script +
+
+

+ The software which is invoked by the server via this + interface. It + need not be a standalone program, but could be a + dynamically-loaded or shared library, or even a subroutine in the + server. It may be a set of statements + interpreted at run-time, as the term 'script' is frequently + understood, but that is not a requirement and within the context + of this specification the term has the broader definition stated. +

+
+
server +
+
+

+ The application program which invokes the script in order to service + requests. +

+
+
+ +

+ + 2. Notational Conventions and Generic Grammar + +

+ +

+ + 2.1. Augmented BNF + +

+

+ All of the mechanisms specified in this document are described in + both prose and an augmented Backus-Naur Form (BNF) similar to that + used by RFC 822 [6]. This augmented BNF contains + the following constructs: +

+
+
name = definition +
+
+

+ The + definition by the equal character ("="). Whitespace is only + significant in that continuation lines of a definition are + indented. +

+
+
"literal" +
+
+

+ Quotation marks (") surround literal text, except for a literal + quotation mark, which is surrounded by angle-brackets ("<" and ">"). + Unless stated otherwise, the text is case-sensitive. +

+
+
rule1 | rule2 +
+
+

+ Alternative rules are separated by a vertical bar ("|"). +

+
+
(rule1 rule2 rule3) +
+
+

+ Elements enclosed in parentheses are treated as a single element. +

+
+
*rule +
+
+

+ A rule preceded by an asterisk ("*") may have zero or more + occurrences. A rule preceded by an integer followed by an asterisk + must occur at least the specified number of times. +

+
+
[rule] +
+
+

+ An element enclosed in square + brackets ("[" and "]") is optional. +

+
+
+ +

+ + 2.2. Basic Rules + +

+

+ The following rules are used throughout this specification to + describe basic parsing constructs. +

+

+ 
+    alpha         = lowalpha | hialpha
+    alphanum      = alpha | digit
+    lowalpha      = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h"
+                    | "i" | "j" | "k" | "l" | "m" | "n" | "o" | "p"
+                    | "q" | "r" | "s" | "t" | "u" | "v" | "w" | "x"
+                    | "y" | "z"
+    hialpha       = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H"
+                    | "I" | "J" | "K" | "L" | "M" | "N" | "O" | "P"
+                    | "Q" | "R" | "S" | "T" | "U" | "V" | "W" | "X"
+                    | "Y" | "Z"
+    digit         = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7"
+                    | "8" | "9"
+    hex           = digit | "A" | "B" | "C" | "D" | "E" | "F" | "a"
+                    | "b" | "c" | "d" | "e" | "f"
+    escaped       = "%" hex hex
+    OCTET         = <any 8-bit sequence of data>
+    CHAR          = <any US-ASCII character (octets 0 - 127)>
+    CTL           = <any US-ASCII control character
+                    (octets 0 - 31) and DEL (127)>
+    CR            = <US-ASCII CR, carriage return (13)>
+    LF            = <US-ASCII LF, linefeed (10)>
+    SP            = <US-ASCII SP, space (32)>
+    HT            = <US-ASCII HT, horizontal tab (9)>
+    NL            = CR | LF
+    LWSP          = SP | HT | NL
+    tspecial      = "(" | ")" | "@" | "," | ";" | ":" | "\" | <">
+                    | "/" | "[" | "]" | "?" | "<" | ">" | "{" | "}"
+                    | SP | HT | NL
+    token         = 1*<any CHAR except CTLs or tspecials>
+    quoted-string = ( <"> *qdtext <"> ) | ( "<" *qatext ">")
+    qdtext        = <any CHAR except <"> and CTLs but including LWSP>
+    qatext        = <any CHAR except "<", ">" and CTLs but
+                    including LWSP>
+    mark          = "-" | "_" | "." | "!" | "~" | "*" | "'" | "(" | ")"
+    unreserved    = alphanum | mark
+    reserved      = ";" | "/" | "?" | ":" | "@" | "&" | "=" |
+                    "$" | ","
+    uric          = reserved | unreserved | escaped
+
+

+ Note that newline (NL) need not be a single character, but can be a + character sequence. +

+ +

+ + 3. Protocol Parameters + +

+ +

+ + 3.1. URL Encoding + +

+

+ Some variables and constructs used here are described as being + 'URL-encoded'. This encoding is described in section + 2 of RFC + 2396 + [4]. +

+

+ An alternate "shortcut" encoding for representing the space + character exists and is in common use. Scripts MUST be prepared to + recognise both '+' and '%20' as an encoded space in a + URL-encoded value. +

+

+ Note that some unsafe characters may have different semantics if + they are encoded. The definition of which characters are unsafe + depends on the context. + For example, the following two URLs do not + necessarily refer to the same resource: +

+

+ 
+    http://somehost.com/somedir%2Fvalue
+    http://somehost.com/somedir/value
+
+

+ See section + 2 of RFC + 2396 [4] + for authoritative treatment of this issue. +

+ +

+ + 3.2. The Script-URI + +

+

+ The 'Script-URI' is defined as the URI of the resource identified + by the metavariables. Often, + this URI will be the same as + the URI requested by the client (the 'Client-URI'); however, it need + not be. Instead, it could be a URI invented by the server, and so it + can only be used in the context of the server and its CGI interface. +

+

+ The Script-URI has the syntax of generic-RL as defined in section 2.1 + of RFC 1808 [7], with the exception that object + parameters and + fragment identifiers are not permitted: +

+

+ 
+    <scheme>://<host><port>/<path>?<query>
+
+

+ The various components of the + Script-URI + are defined by some of the + metavariables (see + section 4 + below); +

+

+ 
+    script-uri = protocol "://" SERVER_NAME ":" SERVER_PORT enc-script
+                 enc-path-info "?" QUERY_STRING
+
+

+ where 'protocol' is obtained + from SERVER_PROTOCOL, 'enc-script' is a + URL-encoded version of SCRIPT_NAME and 'enc-path-info' is a + URL-encoded version of PATH_INFO. See + section 4.6 for more information about the PATH_INFO + metavariable. +

+

+ Note that the scheme and the protocol are not identical; + for instance, a resource accessed via an SSL mechanism + may have a Client-URI with a scheme of "https" + rather than "http". CGI/1.1 provides no means + for the script to reconstruct this, and therefore + the Script-URI includes the base protocol used. +

+ +

+ + 4. Invoking the Script + +

+

+ The + script is invoked in a system defined manner. Unless specified + otherwise, the file containing the script will be invoked as an + executable program. +

+ +

+ + 5. The CGI Script Command Line + +

+

+ Some systems support a method for supplying an array of strings to + the CGI script. This is only used in the case of an 'indexed' query. + This is identified by a "GET" or "HEAD" HTTP request with a URL + query + string not containing any unencoded "=" characters. For such a + request, + servers SHOULD parse the search string + into words, using the following rules: +

+

+ 
+    search-string = search-word *( "+" search-word )
+    search-word   = 1*schar
+    schar         = xunreserved | escaped | xreserved
+    xunreserved   = alpha | digit | xsafe | extra
+    xsafe         = "$" | "-" | "_" | "."
+    xreserved     = ";" | "/" | "?" | ":" | "@" | "&"
+
+

+ After parsing, each word is URL-decoded, optionally encoded in a + system defined manner, + and then the argument list is set to the list + of words. +

+

+ If the server cannot create any part of the argument list, then the + server SHOULD NOT generate any command line information. For example, the + number of arguments may be greater than operating system or server + limitations permit, or one of the words may not be representable as an + argument. +

+

+ Scripts SHOULD check to see if the QUERY_STRING value contains an + unencoded "=" character, and SHOULD NOT use the command line arguments + if it does. +

+ +

+ + 6. Data Input to the CGI Script + +

+

+ Information about a request comes from two different sources: the + request header, and any associated + message-body. + Servers MUST + make portions of this information available to + scripts. +

+ +

+ + 6.1. Request Metadata + (Metavariables) + +

+

+ Each CGI server + implementation MUST define a mechanism + to pass data about the request from + the server to the script. + The metavariables containing these + data + are accessed by the script in a system + defined manner. + The + representation of the characters in the + metavariables is + system defined. +

+

+ This specification does not distinguish between the representation of + null values and missing ones. Whether null or missing values + (such as a query component of "?" or "", respectively) are represented + by undefined metavariables or by metavariables with values of "" is + implementation-defined. +

+

+ Case is not significant in the + metavariable + names, in that there cannot be two + different variables + whose names differ in case only. Here they are + shown using a canonical representation of capitals plus underscore + ("_"). The actual representation of the names is system defined; for + a particular system the representation MAY be defined differently + than this. +

+

+ Metavariable + values MUST be + considered case-sensitive except as noted + otherwise. +

+

+ The canonical + metavariables + defined by this specification are: +

+

+ 
+    AUTH_TYPE
+    CONTENT_LENGTH
+    CONTENT_TYPE
+    GATEWAY_INTERFACE
+    PATH_INFO
+    PATH_TRANSLATED
+    QUERY_STRING
+    REMOTE_ADDR
+    REMOTE_HOST
+    REMOTE_IDENT
+    REMOTE_USER
+    REQUEST_METHOD
+    SCRIPT_NAME
+    SERVER_NAME
+    SERVER_PORT
+    SERVER_PROTOCOL
+    SERVER_SOFTWARE
+
+

+ Metavariables with names beginning with the protocol name (e.g., + "HTTP_ACCEPT") are also canonical in their description of request header + fields. The number and meaning of these fields may change independently + of this specification. (See also section 6.1.5.) +

+ +

+ + 6.1.1. AUTH_TYPE + +

+

+ This variable is specific to requests made + via the + "http" + scheme. +

+

+ If the Script-URI + required access authentication for external + access, then the server + MUST set + the value of + this variable + from the 'auth-scheme' token in + the request's "Authorization" header + field. + Otherwise + it is + set to NULL. +

+

+ 
+    AUTH_TYPE   = "" | auth-scheme
+    auth-scheme = "Basic" | "Digest" | token
+
+

+ HTTP access authentication schemes are described in section 11 of the + HTTP/1.1 specification [8]. The auth-scheme is + not case-sensitive. +

+

+ Servers + MUST + provide this metavariable + to scripts if the request + header included an "Authorization" field + that was authenticated. +

+ +

+ + 6.1.2. CONTENT_LENGTH + +

+

+ This + metavariable + is set to the + size of the message-body + entity attached to the request, if any, in decimal + number of octets. If no data are attached, then this + metavariable + is either NULL or not + defined. The syntax is + the same as for + the HTTP "Content-Length" header field (section 14.14, HTTP/1.1 + specification [8]). +

+

+ 
+    CONTENT_LENGTH = "" | 1*digit
+
+

+ Servers MUST provide this metavariable + to scripts if the request + was accompanied by a + message-body entity. +

+ +

+ + 6.1.3. CONTENT_TYPE + +

+

+ If the request includes a + message-body, + CONTENT_TYPE is set + to + the Internet Media Type + [9] of the attached + entity if the type was provided via + a "Content-type" field in the + request header, or if the server can determine it in the absence + of a supplied "Content-type" field. The syntax is the + same as for the HTTP + "Content-Type" header field. +

+

+ 
+    CONTENT_TYPE = "" | media-type
+    media-type   = type "/" subtype *( ";" parameter)
+    type         = token
+    subtype      = token
+    parameter    = attribute "=" value
+    attribute    = token
+    value        = token | quoted-string
+
+

+ The type, subtype, + and parameter attribute names are not + case-sensitive. Parameter values MAY be case sensitive. + Media types and their use in HTTP are described + in section 3.7 of the + HTTP/1.1 specification [8]. +

+

+ Example: +

+

+ 
+    application/x-www-form-urlencoded
+
+

+ There is no default value for this variable. If and only if it is + unset, then the script MAY attempt to determine the media type from + the data received. If the type remains unknown, then + the script MAY choose to either assume a + content-type of + application/octet-stream + or reject the request with a 415 ("Unsupported Media Type") + error. See section 7.2.1.3 + for more information about returning error status values. +

+

+ Servers MUST provide this metavariable + to scripts if + a "Content-Type" field was present + in the original request header. If the server receives a request + with an attached entity but no "Content-Type" + header field, it MAY attempt to + determine the correct datatype, or it MAY omit this + metavariable when + communicating the request information to the script. +

+ +

+ + 6.1.4. GATEWAY_INTERFACE + +

+

+ This + metavariable + is set to + the dialect of CGI being used + by the server to communicate with the script. + Syntax: +

+

+ 
+    GATEWAY_INTERFACE = "CGI" "/" major "." minor
+    major             = 1*digit
+    minor             = 1*digit
+
+

+ Note that the major and minor numbers are treated as separate + integers and hence each may be + more than a single + digit. Thus CGI/2.4 is a lower version than CGI/2.13 which in turn + is lower than CGI/12.3. Leading zeros in either + the major or the minor number MUST be ignored by scripts and + SHOULD NOT be generated by servers. +

+

+ This document defines the 1.1 version of the CGI interface + ("CGI/1.1"). +

+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.1.5. Protocol-Specific Metavariables + +

+

+ These metavariables are specific to + the protocol + via which the request is made. + Interpretation of these variables depends on the value of + the + SERVER_PROTOCOL + metavariable + (see + section 6.1.17). +

+

+ Metavariables + with names beginning with "HTTP_" contain + values from the request header, if the + scheme used was HTTP. + Each + HTTP header field name is converted to upper case, has all occurrences of + "-" replaced with "_", + and has "HTTP_" prepended to form + the metavariable name. + Similar transformations are applied for other + protocols. + The header data MAY be presented as sent + by the client, or MAY be rewritten in ways which do not change its + semantics. If multiple header fields with the same field-name are received + then the server + MUST rewrite them as though they + had been received as a single header field having the same + semantics before being represented in a + metavariable. + Similarly, a header field that is received on more than one line + MUST be merged into a single line. The server MUST, if necessary, + change the representation of the data (for example, the character + set) to be appropriate for a CGI + metavariable. + +

+

+ Servers are + not required to create + metavariables for all + the request + header fields that they + receive. In particular, + they MAY + decline to make available any + header fields carrying authentication information, such as + "Authorization", or + which are available to the script + via other metavariables, + such as "Content-Length" and "Content-Type". +

+ +

+ + 6.1.6. PATH_INFO + +

+

+ The PATH_INFO + metavariable + specifies + a path to be interpreted by the CGI script. It identifies the + resource or sub-resource to be returned + by the CGI + script, and it is derived from the portion + of the URI path following the script name but preceding + any query data. + The syntax + and semantics are similar to a decoded HTTP URL + 'path' token + (defined in + RFC 2396 + [4]), with the exception + that a PATH_INFO of "/" + represents a single void path segment. +

+

+ 
+    PATH_INFO = "" | ( "/" path )
+    path      = segment *( "/" segment )
+    segment   = *pchar
+    pchar     = <any CHAR except "/">
+
+

+ The PATH_INFO string is the trailing part of the <path> component of + the Script-URI + (see section 3.2) + that follows the SCRIPT_NAME + portion of the path. +

+

+ Servers MAY impose their own restrictions and + limitations on what values they will accept for PATH_INFO, and MAY + reject or edit any values they + consider objectionable before passing + them to the script. +

+

+ Servers MUST make this URI component available + to CGI scripts. The PATH_INFO + value is case-sensitive, and the + server MUST preserve the case of the PATH_INFO element of the URI + when making it available to scripts. +

+ +

+ + 6.1.7. PATH_TRANSLATED + +

+

+ PATH_TRANSLATED is derived by taking any path-info component of the + request URI (see + section 6.1.6), decoding it + (see section 3.1), parsing it as a URI in its own + right, and performing any virtual-to-physical + translation appropriate to map it onto the + server's document repository structure. + If the request URI includes no path-info + component, the PATH_TRANSLATED metavariable SHOULD NOT be defined. +

+

+ 
+    PATH_TRANSLATED = *CHAR
+
+

+ For a request such as the following: +

+

+ 
+    http://somehost.com/cgi-bin/somescript/this%2eis%2epath%2einfo
+
+

+ the PATH_INFO component would be decoded, and the result + parsed as though it were a request for the following: +

+

+ 
+    http://somehost.com/this.is.the.path.info
+
+

+ This would then be translated to a + location in the server's document repository, + perhaps a filesystem path something + like this: +

+

+ 
+    /usr/local/www/htdocs/this.is.the.path.info
+
+

+ The result of the translation is the value of PATH_TRANSLATED. +

+

+ The value of PATH_TRANSLATED may or may not map to a valid + repository + location. + Servers MUST preserve the case of the path-info + segment if and only if the underlying + repository + supports case-sensitive + names. If the + repository + is only case-aware, case-preserving, or case-blind + with regard to + document names, + servers are not required to preserve the + case of the original segment through the translation. +

+

+ The + translation + algorithm the server uses to derive PATH_TRANSLATED is + implementation defined; CGI scripts which use this variable may + suffer limited portability. +

+

+ Servers SHOULD provide this metavariable + to scripts if and only if the request URI includes a + path-info component. +

+ +

+ + 6.1.8. QUERY_STRING + +

+

+ A URL-encoded + string; the <query> part of the + Script-URI. + (See + section 3.2.) +

+

+ 
+    QUERY_STRING = query-string
+    query-string = *uric
+
+

+ The URL syntax for a query + string is described in + section 3 of + RFC 2396 + [4]. +

+

+ Servers MUST supply this value to scripts. + The QUERY_STRING value is case-sensitive. + If the Script-URI does not include a query component, + the QUERY_STRING metavariable MUST be defined as an empty string (""). +

+ +

+ + 6.1.9. REMOTE_ADDR + +

+

+ The IP address of the client + sending the request to the server. This + is not necessarily that of the user + agent + (such as if the request came through a proxy). +

+

+ 
+    REMOTE_ADDR  = hostnumber
+    hostnumber   = ipv4-address | ipv6-address
+
+

+ The definitions of ipv4-address and ipv6-address + are provided in Appendix B of RFC 2373 [13]. +

+

+ Servers MUST supply this value to scripts. +

+ +

+ + 6.1.10. REMOTE_HOST + +

+

+ The fully qualified domain name of the + client sending the request to + the server, if available, otherwise NULL. + (See section 6.1.9.) + Fully qualified domain names take the form as described in + section 3.5 of RFC 1034 [10] and section 2.1 of + RFC 1123 [5]. Domain names are not case sensitive. +

+

+ Servers SHOULD provide this information to + scripts. +

+ +

+ + 6.1.11. REMOTE_IDENT + +

+

+ The identity information reported about the connection by a + RFC 1413 [11] request to the remote agent, if + available. Servers + MAY choose not + to support this feature, or not to request the data + for efficiency reasons. +

+

+ 
+    REMOTE_IDENT = *CHAR
+
+

+ The data returned + may be used for authentication purposes, but the level + of trust reposed in them should be minimal. +

+

+ Servers MAY supply this information to scripts if the + RFC1413 [11] lookup is performed. +

+ +

+ + 6.1.12. REMOTE_USER + +

+

+ If the request required authentication using the "Basic" + mechanism (i.e., the AUTH_TYPE + metavariable is set + to "Basic"), then the value of the REMOTE_USER + metavariable is set to the + user-ID supplied. In all other cases + the value of this metavariable + is undefined. +

+

+ 
+    REMOTE_USER = *OCTET
+
+

+ This variable is specific to requests made via the + HTTP protocol. +

+

+ Servers SHOULD provide this metavariable + to scripts. +

+ +

+ + 6.1.13. REQUEST_METHOD + +

+

+ The REQUEST_METHOD + metavariable + is set to the + method with which the request was made, as described in section + 5.1.1 of the HTTP/1.0 specification [3] and + section 5.1.1 of the + HTTP/1.1 specification [8]. +

+

+ 
+    REQUEST_METHOD   = http-method
+    http-method      = "GET" | "HEAD" | "POST" | "PUT" | "DELETE"
+                       | "OPTIONS" | "TRACE" | extension-method
+    extension-method = token
+
+

+ The method is case sensitive. + CGI/1.1 servers MAY choose to process some methods + directly rather than passing them to scripts. +

+

+ This variable is specific to requests made with HTTP. +

+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.1.14. SCRIPT_NAME + +

+

+ The SCRIPT_NAME + metavariable + is + set to a URL path that could identify the CGI script (rather than the + script's + output). The syntax and semantics are identical to a + decoded HTTP URL 'path' token + (see RFC 2396 + [4]). +

+

+ 
+    SCRIPT_NAME = "" | ( "/" [ path ] )
+
+

+ The SCRIPT_NAME string is some leading part of the <path> component + of the Script-URI derived in some + implementation defined manner. + No PATH_INFO or QUERY_STRING segments + (see sections 6.1.6 and + 6.1.8) are included + in the SCRIPT_NAME value. +

+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.1.15. SERVER_NAME + +

+

+ The SERVER_NAME + metavariable + is set to the + name of the + server, as + derived from the <host> part of the + Script-URI + (see section 3.2). +

+

+ 
+    SERVER_NAME = hostname | hostnumber
+
+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.1.16. SERVER_PORT + +

+

+ The SERVER_PORT + metavariable + is set to the + port on which the + request was received, as used in the <port> + part of the Script-URI. +

+

+ 
+    SERVER_PORT = 1*digit
+
+

+ If the <port> portion of the script-URI is blank, the actual + port number upon which the request was received MUST be supplied. +

+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.1.17. SERVER_PROTOCOL + +

+

+ The SERVER_PROTOCOL + metavariable + is set to + the + name and revision of the information protocol with which + the + request + arrived. This is not necessarily the same as the protocol version used by + the server in its response to the client. +

+

+ 
+    SERVER_PROTOCOL   = HTTP-Version | extension-version
+                        | extension-token
+    HTTP-Version      = "HTTP" "/" 1*digit "." 1*digit
+    extension-version = protocol "/" 1*digit "." 1*digit
+    protocol          = 1*( alpha | digit | "+" | "-" | "." )
+    extension-token   = token
+
+

+ 'protocol' is a version of the <scheme> part of the + Script-URI, but is + not identical to it. For example, the scheme of a request may be + "https" while the protocol remains "http". + The protocol is not case sensitive, but + by convention, 'protocol' is in + upper case. +

+

+ A well-known extension token value is "INCLUDED", + which signals that the current document is being included as part of + a composite document, rather than being the direct target of the + client request. +

+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.1.18. SERVER_SOFTWARE + +

+

+ The SERVER_SOFTWARE + metavariable + is set to the + name and version of the information server software answering the + request (and running the gateway). +

+

+ 
+    SERVER_SOFTWARE = 1*product
+    product         = token [ "/" product-version ]
+    product-version = token
+
+

+ Servers MUST provide this metavariable + to scripts. +

+ +

+ + 6.2. Request Message-Bodies + +

+

+ As there may be a data entity attached to the request, there MUST be + a system defined method for the script to read + these data. Unless + defined otherwise, this will be via the 'standard input' file + descriptor. +

+

+ If the CONTENT_LENGTH value (see section 6.1.2) + is non-NULL, the server MUST supply at least that many bytes to + scripts on the standard input stream. + Scripts are + not obliged to read the data. + Servers MAY signal an EOF condition after CONTENT_LENGTH bytes have been + read, but are + not obligated to do so. Therefore, scripts + MUST NOT + attempt to read more than CONTENT_LENGTH bytes, even if more data + are available. +

+

+ For non-parsed header (NPH) scripts (see + section 7.1 + below), + servers SHOULD + attempt to ensure that the data + supplied to the script are precisely + as supplied by the client and unaltered by + the server. +

+

+ Section 8.1.2 describes the requirements of + servers with regard to requests that include + message-bodies. +

+ +

+ + 7. Data Output from the CGI Script + +

+

+ There MUST be a system defined method for the script to send data + back to the server or client; a script MUST always return some data. + Unless defined otherwise, this will be via the 'standard + output' file descriptor. +

+

+ There are two forms of output that scripts can supply to servers: non-parsed + header (NPH) output, and parsed header output. + Servers MUST support parsed header + output and MAY support NPH output. The method of + distinguishing between the two + types of output (or scripts) is implementation defined. +

+

+ Servers MAY implement a timeout period within which data must be + received from scripts. If a server implementation defines such + a timeout and receives no data from a script within the timeout + period, the server MAY terminate the script process and SHOULD + abort the client request with + either a + '504 Gateway Timed Out' or a + '500 Internal Server Error' response. +

+ +

+ + 7.1. Non-Parsed Header Output + +

+

+ Scripts using the NPH output form + MUST return a complete HTTP response message, as described + in Section 6 of the HTTP specifications + [3,8]. + NPH scripts + MUST use the SERVER_PROTOCOL variable to determine the appropriate format + for a response. +

+

+ Servers + SHOULD attempt to ensure that the script output is sent + directly to the client, with minimal + internal and no transport-visible + buffering. +

+ +

+ + 7.2. Parsed Header Output + +

+

+ Scripts using the parsed header output form MUST supply + a CGI response message to the server + as follows: +

+

+ 
+    CGI-Response   = *optional-field CGI-Field *optional-field NL [ Message-Body ]
+    optional-field = ( CGI-Field | HTTP-Field )
+    CGI-Field      = Content-type
+                   | Location
+                   | Status
+                   | extension-header
+
+

+ The response comprises a header and a body, separated by a blank line. + The body may be NULL. + The header fields are either CGI header fields to be interpreted by + the server, or HTTP header fields + to be included in the response returned + to the client + if the request method is HTTP. At least one + CGI-Field MUST be + supplied, but no CGI field name may be used more than once + in a response. + If a body is supplied, then a "Content-type" + header field MUST be + supplied by the script, + otherwise the script MUST send a "Location" + or "Status" header field. If a + Location CGI-Field + is returned, then the script MUST NOT supply + any HTTP-Fields. +

+

+ Each header field in a CGI-Response MUST be specified on a single line; + CGI/1.1 does not support continuation lines. +

+ +

+ + 7.2.1. CGI header fields + +

+

+ The CGI header fields have the generic syntax: +

+

+ 
+    generic-field  = field-name ":" [ field-value ] NL
+    field-name     = token
+    field-value    = *( field-content | LWSP )
+    field-content  = *( token | tspecial | quoted-string )
+
+

+ The field-name is not case sensitive; a NULL field value is + equivalent to the header field not being sent. +

+ +

+ + 7.2.1.1. Content-Type + +

+

+ The Internet Media Type [9] of the entity + body, which is to be sent unmodified to the client. +

+

+ 
+    Content-Type = "Content-Type" ":" media-type NL
+
+

+ This is actually an HTTP-Field + rather than a CGI-Field, but + it is listed here because of its importance in the CGI dialogue as + a member of the "one of these is required" set of header + fields. +

+ +

+ + 7.2.1.2. Location + +

+

+ This is used to specify to the server that the script is returning a + reference to a document rather than an actual document. +

+

+ 
+    Location         = "Location" ":"
+                       ( fragment-URI | rel-URL-abs-path ) NL
+    fragment-URI     = URI [ # fragmentid ]
+    URI              = scheme ":" *qchar
+    fragmentid       = *qchar
+    rel-URL-abs-path = "/" [ hpath ] [ "?" query-string ]
+    hpath            = fpsegment *( "/" psegment )
+    fpsegment        = 1*hchar
+    psegment         = *hchar
+    hchar            = alpha | digit | safe | extra
+                       | ":" | "@" | "& | "="
+
+

+ The Location + value is either an absolute URI with optional fragment, + as defined in RFC 1630 [1], or an absolute path + within the server's URI space (i.e., + omitting the scheme and network-related fields) and optional + query-string. If an absolute URI is returned by the script, + then the + server MUST generate a + '302 redirect' HTTP response + message unless the script has supplied an + explicit Status response header field. + Scripts returning an absolute URI MAY choose to + provide a message-body. Servers MUST make any appropriate modifications + to the script's output to ensure the response to the user-agent complies + with the response protocol version. + If the Location value is a path, then the server + MUST generate + the response that it would have produced in response to a request + containing the URL +

+

+ 
+    scheme "://" SERVER_NAME ":" SERVER_PORT rel-URL-abs-path
+
+

+ Note: If the request was accompanied by a + message-body + (such as for a POST request), and the script + redirects the request with a Location field, the + message-body + may not be + available to the resource that is the target of the redirect. +

+ +

+ + 7.2.1.3. Status + +

+

+ The "Status" header field is used to indicate to the server what + status code the server MUST use in the response message. +

+

+ 
+    Status        = "Status" ":" digit digit digit SP reason-phrase NL
+    reason-phrase = *<CHAR, excluding CTLs, NL>
+
+

+ The valid status codes are listed in section 6.1.1 of the HTTP/1.0 + specifications [3]. If the SERVER_PROTOCOL is + "HTTP/1.1", then the status codes defined in the HTTP/1.1 + specification [8] may + be used. If the script does not return a "Status" header + field, then "200 OK" SHOULD be assumed by the server. +

+

+ If a script is being used to handle a particular error or condition + encountered by the server, such as a '404 Not Found' error, the script + SHOULD use the "Status" CGI header field to propagate the error + condition back to the client. E.g., in the example mentioned it + SHOULD include a "Status: 404 Not Found" in the + header data returned to the server. +

+ +

+ + 7.2.1.4. Extension header fields + +

+

+ Scripts MAY include in their CGI response header additional fields + not defined in this or the HTTP specification. + These are called "extension" fields, + and have the syntax of a generic-field as defined in + section 7.2.1. The name of an extension field + MUST NOT conflict with a field name defined in this or any other + specification; extension field names SHOULD begin with "X-CGI-" + to ensure uniqueness. +

+ +

+ + 7.2.2. HTTP header fields + +

+

+ The script MAY return any other header fields defined by the + specification + for the SERVER_PROTOCOL (HTTP/1.0 [3] or HTTP/1.1 + [8]). + Servers MUST resolve conflicts beteen CGI header + and HTTP header formats or names (see section 8). +

+ +

+ + 8. Server Implementation + +

+

+ This section defines the requirements that must be met by HTTP + servers in order to provide a coherent and correct CGI/1.1 + environment in which scripts may function. It is intended + primarily for server implementors, but it is useful for + script authors to be familiar with the information as well. +

+ +

+ + 8.1. Requirements for Servers + +

+

+ In order to be considered CGI/1.1-compliant, a server must meet + certain basic criteria and provide certain minimal functionality. + The details of these requirements are described in the following sections. +

+ +

+ + 8.1.1. Script-URI + +

+

+ Servers MUST support the standard mechanism (described below) which + allows + script authors to determine + what URL to use in documents + which reference the script; + specifically, what URL to use in order to + achieve particular settings of the + metavariables. This + mechanism is as follows: +

+

+ The server + MUST translate the header data from the CGI header field syntax to + the HTTP + header field syntax if these differ. For example, the character + sequence for + newline (such as Unix's ASCII NL) used by CGI scripts may not be the + same as that used by HTTP (ASCII CR followed by LF). The server MUST + also resolve any conflicts between header fields returned by the script + and header fields that it would otherwise send itself. +

+ +

+ + 8.1.2. Request Message-body Handling + +

+

+ These are the requirements for server handling of message-bodies directed + to CGI/1.1 resources: +

+
    +
  1. The message-body the server provides to the CGI script MUST + have any transfer encodings removed. +
    2. +
  2. The server MUST derive and provide a value for the CONTENT_LENGTH + metavariable that reflects the length of the message-body after any + transfer decoding. +
    3. +
  3. The server MUST leave intact any content-encodings of the message-body. +
    4. +
+ +

+ + 8.1.3. Required Metavariables + +

+

+ Servers MUST provide scripts with certain information and + metavariables + as described in section 8.3. +

+ +

+ + 8.1.4. Response Compliance + +

+

+ Servers MUST ensure that responses sent to the user-agent meet all + requirements of the protocol level in effect. This may involve + modifying, deleting, or augmenting any header + fields and/or message-body supplied by the script. +

+ +

+ + 8.2. Recommendations for Servers + +

+

+ Servers SHOULD provide the "query" component of the script-URI + as command-line arguments to scripts if it does not + contain any unencoded '=' characters and the command-line arguments can + be generated in an unambiguous manner. + (See section 5.) +

+

+ Servers SHOULD set the AUTH_TYPE + metavariable to the value of the + 'auth-scheme' token of the "Authorization" + field if it was supplied as part of the request header. + (See section 6.1.1.) +

+

+ Where applicable, servers SHOULD set the current working directory + to the directory in which the script is located before invoking + it. +

+

+ Servers MAY reject with error '404 Not Found' + any requests that would result in + an encoded "/" being decoded into PATH_INFO or SCRIPT_NAME, as this + might represent a loss of information to the script. +

+

+ Although the server and the CGI script need not be consistent in + their handling of URL paths (client URLs and the PATH_INFO data, + respectively), server authors may wish to impose consistency. + So the server implementation SHOULD define its behaviour for the + following cases: +

+
    +
  1. define any restrictions on allowed characters, in particular + whether ASCII NUL is permitted; +
    2. +
  2. define any restrictions on allowed path segments, in particular + whether non-terminal NULL segments are permitted; +
    3. +
  3. define the behaviour for "." or ".." path + segments; i.e., whether they are prohibited, treated as + ordinary path + segments or interpreted in accordance with the relative URL + specification [7]; +
    4. +
  4. define any limits of the implementation, including limits on path or + search string lengths, and limits on the volume of header data the server + will parse. +
    5. +
+

+ Servers MAY generate the + Script-URI in + any way from the client URI, + or from any other data (but the behaviour SHOULD be documented). +

+

+ For non-parsed header (NPH) scripts (see + section 7.1), servers SHOULD + attempt to ensure that the script input comes directly from the + client, with minimal buffering. For all scripts the data will be + as supplied by the client. +

+ +

+ + 8.3. Summary of + MetaVariables + +

+

+ Servers MUST provide the following + metavariables to + scripts. See the individual descriptions for exceptions and semantics. +

+

+ 
+    CONTENT_LENGTH (section 6.1.2)
+    CONTENT_TYPE (section 6.1.3)
+    GATEWAY_INTERFACE (section 6.1.4)
+    PATH_INFO (section 6.1.6)
+    QUERY_STRING (section 6.1.8)
+    REMOTE_ADDR (section 6.1.9)
+    REQUEST_METHOD (section 6.1.13)
+    SCRIPT_NAME (section 6.1.14)
+    SERVER_NAME (section 6.1.15)
+    SERVER_PORT (section 6.1.16)
+    SERVER_PROTOCOL (section 6.1.17)
+    SERVER_SOFTWARE (section 6.1.18)
+
+

+ Servers SHOULD define the following + metavariables for scripts. + See the individual descriptions for exceptions and semantics. +

+

+ 
+    AUTH_TYPE (section 6.1.1)
+    REMOTE_HOST (section 6.1.10)
+
+

+ In addition, servers SHOULD provide + metavariables for all fields present + in the HTTP request header, with the exception of those involved with + access control. Servers MAY at their discretion provide + metavariables + for access control fields. +

+

+ Servers MAY define the following + metavariables. See the individual + descriptions for exceptions and semantics. +

+

+ 
+    PATH_TRANSLATED (section 6.1.7)
+    REMOTE_IDENT (section 6.1.11)
+    REMOTE_USER (section 6.1.12)
+
+

+ Servers MAY + at their discretion define additional implementation-specific + extension metavariables + provided their names do not + conflict with defined header field names. Implementation-specific + metavariable names SHOULD + be prefixed with "X_" (e.g., + "X_DBA") to avoid the potential for such conflicts. +

+ +

+ + 9. + Script Implementation + +

+

+ This section defines the requirements and recommendations for scripts + that are intended to function in a CGI/1.1 environment. It is intended + primarily as a reference for script authors, but server implementors + should be familiar with these issues as well. +

+ +

+ + 9.1. Requirements for Scripts + +

+

+ Scripts using the parsed-header method to communicate with servers + MUST supply a response header to the server. + (See section 7.) +

+

+ Scripts using the NPH method to communicate with servers MUST + provide complete HTTP responses, and MUST use the value of the + SERVER_PROTOCOL metavariable + to determine the appropriate format. + (See section 7.1.) +

+

+ Scripts MUST check the value of the REQUEST_METHOD + metavariable in order + to provide an appropriate response. + (See section 6.1.13.) +

+

+ Scripts MUST be prepared to handled URL-encoded values in + metavariables. + In addition, they MUST recognise both "+" and "%20" in URL-encoded + quantities as representing the space character. + (See section 3.1.) +

+

+ Scripts MUST ignore leading zeros in the major and minor version numbers + in the GATEWAY_INTERFACE + metavariable value. (See + section 6.1.4.) +

+

+ When processing requests that include a + message-body, scripts + MUST NOT read more than CONTENT_LENGTH bytes from the input stream. + (See sections 6.1.2 and 6.2.) +

+ +

+ + 9.2. Recommendations for Scripts + +

+

+ Servers may interrupt or terminate script execution at any time + and without warning, so scripts SHOULD be prepared to deal with + abnormal termination. +

+

+ Scripts MUST + reject with + error '405 Method Not + Allowed' requests + made using methods that they do not support. If the script does + not intend + processing the PATH_INFO data, then it SHOULD reject the request with + '404 Not + Found' if PATH_INFO is not NULL. +

+

+ If a script is processing the output of a form, it SHOULD + verify that the CONTENT_TYPE + is "application/x-www-form-urlencoded" [2] + or whatever other media type is expected. +

+

+ Scripts parsing PATH_INFO, + PATH_TRANSLATED, or SCRIPT_NAME + SHOULD be careful + of void path segments ("//") and special path segments + ("." and + ".."). They SHOULD either be removed from the path before + use in OS + system calls, or the request SHOULD be rejected with + '404 Not Found'. +

+

+ As it is impossible for + scripts to determine the client URI that + initiated a + request without knowledge of the specific server in + use, the script SHOULD NOT return "text/html" + documents containing + relative URL links without including a "<BASE>" + tag in the document. +

+

+ When returning header fields, + scripts SHOULD try to send the CGI + header fields (see section + 7.2) as soon as possible, and + SHOULD send them + before any HTTP header fields. This may + help reduce the server's memory requirements. +

+ +

+ + 10. System Specifications + +

+ +

+ + 10.1. AmigaDOS + +

+

+ The implementation of the CGI on an AmigaDOS operating system platform + SHOULD use environment variables as the mechanism of providing + request metadata to CGI scripts. +

+
+
Environment variables +
+
+

+ These are accessed by the DOS library routine GetVar. The + flags argument SHOULD be 0. Case is ignored, but upper case is + recommended for compatibility with case-sensitive systems. +

+
+
The current working directory +
+
+

+ The current working directory for the script is set to the directory + containing the script. +

+
+
Character set +
+
+

+ The US-ASCII character set is used for the definition of environment + variable names and header + field names; the newline (NL) sequence is LF; + servers SHOULD also accept CR LF as a newline. +

+
+
+ +

+ + 10.2. Unix + +

+

+ The implementation of the CGI on a UNIX operating system platform + SHOULD use environment variables as the mechanism of providing + request metadata to CGI scripts. +

+

+ For Unix compatible operating systems, the following are defined: +

+
+
Environment variables +
+
+

+ These are accessed by the C library routine getenv. +

+
+
The command line +
+
+

+ This is accessed using the + argc and argv + arguments to main(). The words have any characters + that + are 'active' in the Bourne shell escaped with a backslash. + If the value of the QUERY_STRING + metavariable + contains an unencoded equals-sign '=', then the command line + SHOULD NOT be used by the script. +

+
+
The current working directory +
+
+

+ The current working directory for the script + SHOULD be set to the directory + containing the script. +

+
+
Character set +
+
+

+ The US-ASCII character set is used for the definition of environment + variable names and header field names; the newline (NL) sequence is LF; + servers SHOULD also accept CR LF as a newline. +

+
+
+ +

+ + 11. Security Considerations + +

+ +

+ + 11.1. Safe Methods + +

+

+ As discussed in the security considerations of the HTTP + specifications [3,8], the + convention has been established that the + GET and HEAD methods should be 'safe'; they should cause no + side-effects and only have the significance of resource retrieval. +

+

+ CGI scripts are responsible for enforcing any HTTP security considerations + [3,8] + with respect to the protocol version level of the request and + any side effects generated by the scripts on behalf of + the server. Primary + among these + are the considerations of safe and idempotent methods. Idempotent + requests are those that may be repeated an arbitrary number of times + and produce side effects identical to a single request. +

+ +

+ + 11.2. HTTP Header + Fields Containing Sensitive Information + +

+

+ Some HTTP header fields may carry sensitive information which the server + SHOULD NOT pass on to the script unless explicitly configured to do + so. For example, if the server protects the script using the + "Basic" + authentication scheme, then the client will send an + "Authorization" + header field containing a username and password. If the server, rather + than the script, validates this information then the password SHOULD + NOT be passed on to the script via the HTTP_AUTHORIZATION + metavariable + without careful consideration. + This also applies to the + Proxy-Authorization header field and the corresponding + HTTP_PROXY_AUTHORIZATION + metavariable. +

+ +

+ + 11.3. Script + Interference with the Server + +

+

+ The most common implementation of CGI invokes the script as a child + process using the same user and group as the server process. It + SHOULD therefore be ensured that the script cannot interfere with the + server process, its configuration, or documents. +

+

+ If the script is executed by calling a function linked in to the + server software (either at compile-time or run-time) then precautions + SHOULD be taken to protect the core memory of the server, or to + ensure that untrusted code cannot be executed. +

+ +

+ + 11.4. Data Length and Buffering Considerations + +

+

+ This specification places no limits on the length of message-bodies + presented to the script. Scripts should not assume that statically + allocated buffers of any size are sufficient to contain the entire + submission at one time. Use of a fixed length buffer without careful + overflow checking may result in an attacker exploiting 'stack-smashing' + or 'stack-overflow' vulnerabilities of the operating system. + Scripts may spool large submissions to disk or other buffering media, + but a rapid succession of large submissions may result in denial of + service conditions. If the CONTENT_LENGTH of a message-body is larger + than resource considerations allow, scripts should respond with an + error status appropriate for the protocol version; potentially applicable + status codes include '503 Service Unavailable' (HTTP/1.0 and HTTP/1.1), + '413 Request Entity Too Large' (HTTP/1.1), and + '414 Request-URI Too Long' (HTTP/1.1). +

+ +

+ + 11.5. Stateless Processing + +

+

+ The stateless nature of the Web makes each script execution and resource + retrieval independent of all others even when multiple requests constitute a + single conceptual Web transaction. Because of this, a script should not + make any assumptions about the context of the user-agent submitting a + request. In particular, scripts should examine data obtained from the client + and verify that they are valid, both in form and content, before allowing + them to be used for sensitive purposes such as input to other + applications, commands, or operating system services. These uses + include, but are not + limited to: system call arguments, database writes, dynamically evaluated + source code, and input to billing or other secure processes. It is important + that applications be protected from invalid input regardless of whether + the invalidity is the result of user error, logic error, or malicious action. +

+

+ Authors of scripts involved in multi-request transactions should be + particularly cautios about validating the state information; + undesirable effects may result from the substitution of dangerous + values for portions of the submission which might otherwise be + presumed safe. Subversion of this type occurs when alterations + are made to data from a prior stage of the transaction that were + not meant to be controlled by the client (e.g., hidden + HTML form elements, cookies, embedded URLs, etc.). +

Since +this obviously requires a shell to interpret the scripts the feature +depends on having a shell built into the binary. Either ash or hush +will do. If both are present ash will be used. Support for embedded +scripts also has to be enabled. + +It's unlikely that your applet will be implemented as a pure shell +script: it will probably need some external commands. If these are +to be provided by BusyBox you'll need to ensure they're enabled too. + +There are two ways to include scripts in BusyBox: the quick-and-dirty +custom script and the full-featured scripted applet. + +Custom Scripts +-------------- + +When embedded script support is enabled the BusyBox build process +assumes that any files in the directory 'embed' at the top level of +the source tree are scripts to be embedded. + +The embed directory isn't present in the BusyBox source tree and +BusyBox itself will never put anything there: it's entirely for the +use of third parties. + +Adding a custom script is as simple as running the following sequence +of commands in the BusyBox source directory: + + mkdir embed + echo 'echo foo' >embed/foo + make defconfig + make + +The resulting binary includes the new applet foo! + +Custom scripts have limited opportunities for configuration: the only +control developers have is to put them in the embed directory, or not. +Everything else takes default values. For more control you need the +additional features provided by scripted applets. + +Scripted Applets +---------------- + +Suppose we want to make a shell script version of the sample applet +from the New Applet HOWTO. First we'd have to write a script (vaguely) +equivalent to the C code: + + return $(($RANDOM%256)) + +This should be placed in the file applets_sh/mu in the source tree. + +Next we need the configuration data. This is very similar to the example +code for the native applet: + +//config:config MU +//config: bool "MU" +//config: default y +//config: help +//config: Returns an indeterminate value. + +//applet:IF_MU(APPLET_SCRIPTED(mu, scripted, BB_DIR_USR_BIN, BB_SUID_DROP, mu)) + +//usage:#define mu_trivial_usage +//usage: "[-abcde] FILE..." +//usage:#define mu_full_usage +//usage: "Returns an indeterminate value\n" +//usage: "\n -a First function" +//usage: "\n -b Second function" + +The only difference is that the applet is specified as being of type +APPLET_SCRIPTED. It would also be useful to include details of any +dependencies the script has. No external commands are used by our mu +script, but it does depend on optional shell features. We can ensure +these are selected by adding this to the configuration: + +//config:config MU_DEPENDENCIES +//config: bool "Enable dependencies for mu" +//config: default y +//config: depends on MU +//config: select ASH_RANDOM_SUPPORT +//config: select FEATURE_SH_MATH +//config: help +//config: mu is implemented as a shell script. It requires support +//config: for $RANDOM and arithmetic. + +The configuration data should be placed in a C file in an appropriate +subdirectory. There isn't any C code, though! In this case the file +could be miscutils/mu.c. + +Scripted applets are just as configurable as applets written in C. +They can be enabled or disabled using the configuration menu; their +install directory can be specified and their usage messages are stored +along with those of all other applets. + +Additional Notes +---------------- + +The source for embedded scripts can be displayed by running: + + busybox --show SCRIPT + +This can be disabled by turning off FEATURE_SHOW_SCRIPT in the +configuration, though it won't prevent a determined user from +extracting the source code. + +It can be argued that embedded scripts are linked into the BusyBox +binary and are therefore not subject to the 'mere aggregation' +exception in the GPL.

For +everyone else, mdev is a weird black box that they hear is awesome, but can't +seem to get their head around how it works. Thus, a primer. + +----------- + Basic Use +----------- + +Mdev has two primary uses: initial population and dynamic updates. Both +require sysfs support in the kernel and have it mounted at /sys. For dynamic +updates, you also need to have hotplugging enabled in your kernel. + +Here's a typical code snippet from the init script: +[0] mount -t proc proc /proc +[1] mount -t sysfs sysfs /sys +[2] echo /sbin/mdev > /proc/sys/kernel/hotplug +[3] mdev -s + +Alternatively, without procfs the above becomes: +[1] mount -t sysfs sysfs /sys +[2] sysctl -w kernel.hotplug=/sbin/mdev +[3] mdev -s + + +Of course, a more "full" setup would entail executing this before the previous +code snippet: +[4] mount -t tmpfs -o size=64k,mode=0755 tmpfs /dev +[5] mkdir /dev/pts +[6] mount -t devpts devpts /dev/pts + +The simple explanation here is that [1] you need to have /sys mounted before +executing mdev. Then you [2] instruct the kernel to execute /sbin/mdev whenever +a device is added or removed so that the device node can be created or +destroyed. Then you [3] seed /dev with all the device nodes that were created +while the system was booting. + +For the "full" setup, you want to [4] make sure /dev is a tmpfs filesystem +(assuming you're running out of flash). Then you want to [5] create the +/dev/pts mount point and finally [6] mount the devpts filesystem on it. + +------------- + MDEV Config (/etc/mdev.conf) +------------- + +Mdev has an optional config file for controlling ownership/permissions of +device nodes if your system needs something more than the default root/root +660 permissions. + +The file has the format: + [-][envmatch] : +or + [envmatch]@ : +or + $envvar= : + +For example: + hd[a-z][0-9]* 0:3 660 + +The config file parsing stops at the first matching line unless this line +starts with "-". If no line is matched, then the default of 0:0 660 is used. +To set your own default, simply create your own total match like so: + + .* 1:1 777 + +You can rename/move device nodes by using the next optional field. + + : [=path] + +So if you want to place the device node into a subdirectory, make sure the path +has a trailing /. If you want to rename the device node, just place the name. + hda 0:3 660 =drives/ +This will move "hda" into the drives/ subdirectory. + hdb 0:3 660 =cdrom +This will rename "hdb" to "cdrom". + +Similarly, ">path" renames/moves the device but it also creates +a direct symlink /dev/DEVNAME to the renamed/moved device. + +You can also prevent creation of device nodes with the 4th field as "!": + tty[a-z]. 0:0 660 ! + pty[a-z]. 0:0 660 ! + +If you also enable support for executing your own commands, then the file has +the format: + : [=path] [@|$|*] + or + : [>path] [@|$|*] + or + : [!] [@|$|*] + +For example: +---8<--- +# block devices +([hs]d[a-z]) root:disk 660 >disk/%1/0 +([hs]d[a-z])([0-9]+) root:disk 660 >disk/%1/%2 +mmcblk([0-9]+) root:disk 660 >disk/mmc/%1/0 +mmcblk([0-9]+)p([0-9]+) root:disk 660 >disk/mmc/%1/%2 +# network devices +(tun|tap) root:network 660 >net/%1 +---8<--- + +The special characters have the meaning: + @ Run after creating the device. + $ Run before removing the device. + * Run both after creating and before removing the device. + +The command is executed via the system() function (which means you're giving a +command to the shell), so make sure you have a shell installed at /bin/sh. You +should also keep in mind that the kernel executes hotplug helpers with stdin, +stdout, and stderr connected to /dev/null. + +For your convenience, the shell env var $MDEV is set to the device name. So if +the device "hdc" was matched, MDEV would be set to "hdc". + +---------- + FIRMWARE +---------- + +Some kernel device drivers need to request firmware at runtime in order to +properly initialize a device. Place all such firmware files into the +/lib/firmware/ directory. At runtime, the kernel will invoke mdev with the +filename of the firmware which mdev will load out of /lib/firmware/ and into +the kernel via the sysfs interface. The exact filename is hardcoded in the +kernel, so look there if you need to know how to name the file in userspace. + +------------ + SEQUENCING +------------ + +Kernel does not serialize hotplug events. It increments SEQNUM environmental +variable for each successive hotplug invocation. Normally, mdev doesn't care. +This may reorder hotplug and hot-unplug events, with typical symptoms of +device nodes sometimes not created as expected. + +However, if /dev/mdev.seq file is found, mdev will compare its +contents with SEQNUM. It will retry up to two seconds, waiting for them +to match. If they match exactly (not even trailing '\n' is allowed), +or if two seconds pass, mdev runs as usual, then it rewrites /dev/mdev.seq +with SEQNUM+1. + +IOW: this will serialize concurrent mdev invocations. + +If you want to activate this feature, execute "echo >/dev/mdev.seq" prior to +setting mdev to be the hotplug handler. This writes single '\n' to the file. +NB: mdev recognizes /dev/mdev.seq consisting of single '\n' character +as a special case. IOW: this will not make your first hotplug event +to stall for two seconds. diff --git a/busybox-1.37.0/docs/new-applet-HOWTO.txt b/busybox-1.37.0/docs/new-applet-HOWTO.txt new file mode 100644 index 00000000000..619d47fb8fb --- /dev/null +++ b/busybox-1.37.0/docs/new-applet-HOWTO.txt @@ -0,0 +1,207 @@ +How to Add a New Applet to BusyBox +================================== + +This document details the steps you must take to add a new applet to BusyBox. + +Credits: +Matt Kraai - initial writeup +Mark Whitley - the remix +Thomas Lundquist - trying to keep it updated + +When doing this you should consider using the latest git HEAD. +This is a good thing if you plan to getting it committed into mainline. + +Initial Write +------------- + +First, write your applet.

Return value + is taken from xfunc_error_retval. + - fflush_stdout_and_exit(n) is ok to use. +* do not use shared global data, or save/restore shared global data + (e.g. bb_common_bufsiz1) prior to returning. + - getopt32() is ok to use. You do not need to save/restore option_mask32, + xfunc_error_retval, and logmode - it is already done by core code. +* if you allocate memory, you can use xmalloc() only on the very first + allocation. All other allocations should use malloc[_or_warn](). + After first allocation, you cannot use any xfuncs. + Otherwise, failing xfunc will return to caller applet + without freeing malloced data! +* the same applies to other resources, such as open fds: no xfuncs after + acquiring them! +* All allocated data, opened files, signal handlers, termios settings + etc should be freed/closed/restored prior to return. + +Currently, ash shell signal handling is implemented in a way that signals +have non-SA_RESTARTed handlers. This means that system calls can +return EINTR. An example of such problem is "yes" applet: +it is implemented so that it has a writing loop, this loop is exited on +any write error, and in the case of user pressing ^C the error was EINTR. +The problem is, the error causes stdout FILE* object to get into error +state, needing clearerr() - or else subsequent shell output will also +not work. ("yes" has been downgraded to NOEXEC, since hush signal handling +does not have this problem - which makes "yes" to not exit on ^C (bug). +But stray EINTRs can be seen in any NOFORK under ash, until ash is fixed). + +NOFORK applets give the most of speed advantage, but are trickiest +to implement. In order to minimize amount of bugs and maintenance, +prime candidates for NOFORK-ification are those applets which +are small and easy to audit, and those which are more likely to be +frequently executed from shell/find/xargs, particularly in shell +script loops. Applets which mess with signal handlers, termios etc +are probably not worth the effort. + +Applets which must be interruptible by ^C in shells can not be NOFORKs. + +Any NOFORK applet is also a NOEXEC applet. + + + Calling NOFORK applets + +API to call NOFORK applets is two functions: + + run_nofork_applet(appno, argv) + spawn_and_wait(argv) // only if FEATURE_PREFER_APPLETS=y + +First one is directly used by shells if FEATURE_SH_NOFORK=y. +Second one is used by many applets, but main users are xargs and find. +It itself calls run_nofork_applet(), if argv[0] is a name +of a NOFORK applet. + +run_nofork_applet() saves/inits/restores option parsing, xfunc_error_retval, +logmode, applet_name.

Proper handling of SIGINT/SIGQUIT

+ +

+ + + + + +
Abstract: +In UNIX terminal sessions, you usually have a key like +C-c (Control-C) to immediately end whatever program you +have running in the foreground. This should work even when the program +you called has called other programs in turn. Everything should be +aborted, giving you your command prompt back, no matter how deep the +call stack is. + +

Basically, it's trivial. But the existence of interactive +applications that use SIGINT and/or SIGQUIT for other purposes than a +complete immediate abort make matters complicated, and - as was to +expect - left us with several ways to solve the problems. Of course, +existing shells and applications follow different ways. + +

This Web pages outlines different ways to solve the problem and +argues that only one of them can do everything right, although it +means that we have to fix some existing software. + + + +

Intended audience: Programmers who implement programs that catch SIGINT/SIGQUIT. +
Programmers who implements shells or shell-like programs that +execute batches of programs. + +

Users who have problems problems getting rid of runaway shell +scripts using Control-C. Or have interactive applications +that don't behave right when sending SIGINT. Examples are emacs'es +that die on Control-g or shellscript statements that sometimes are +executed and sometimes not, apparently not determined by the user's +intention. + + +

Required knowledge: You have to know what it means to catch SIGINT or SIGQUIT and how +processes are waiting for other processes (children) they spawned. + + +
+ + + +

Basic concepts

+ +What technically happens when you press Control-C is that all programs +running in the foreground in your current terminal (or virtual +terminal) get the signal SIGINT sent. + +

You may change the key that triggers the signal using +stty and running programs may remap the SIGINT-sending +key at any time they like, without your intervention and without +asking you first. + +

The usual reaction of a running program to SIGINT is to exit. +However, not all program do an exit on SIGINT, programs are free to +use the signal for other actions or to ignore it at all. + +

All programs running in the foreground receive the signal. This may +be a nested "stack" of programs: You started a program that started +another and the outer is waiting for the inner to exit. This nesting +may be arbitrarily deep. + +

The innermost program is the one that decides what to do on SIGINT. +It may exit, do something else or do nothing. Still, when the user hit +SIGINT, all the outer programs are awaken, get the signal and may +react on it. + +

What we try to achieve

+ +The problem is with shell scripts (or similar programs that call +several subprograms one after another). + +

Let us consider the most basic script: +

+#! /bin/sh
+program1
+program2
+
+and the usual run looks like this: +
+$ sh myscript
+[output of program1]
+[output of program2]
+$
+
+ +

Let us assume that both programs do nothing special on SIGINT, they +just exit. + +

Now imagine the user hits C-c while a shellscript is executing its +first program. The following programs receive SIGINT: program1 and +also the shell executing the script. program1 exits. + +

But what should the shell do? If we say that it is only the +innermost's programs business to react on SIGINT, the shell will do +nothing special (not exit) and it will continue the execution of the +script and run program2. But this is wrong: The user's intention in +hitting C-c is to abort the whole script, to get his prompt back. If +he hits C-c while the first program is running, he does not want +program2 to be even started. + +

here is what would happen if the shell doesn't do anything: +

+$ sh myscript
+[first half of program1's output]
+C-c   [users presses C-c]
+[second half of program1's output will not be displayed]
+[output of program2 will appear]
+
+ + +

Consider a more annoying example: +

+#! /bin/sh
+# let's assume there are 300 *.dat files
+for file in *.dat ; do
+	dat2ascii $dat
+done
+
+ +If your shell wouldn't end if the user hits C-c, +C-c would just end one dat2ascii run and +the script would continue. Thus, you had to hit C-c up to +300 times to end this script. + +

Alternatives to do so

+ +

There are several ways to handle abortion of shell scripts when +SIGINT is received while a foreground child runs: + +

+ +
  • As just outlined, the shellscript may just continue, ignoring the +fact that the user hit C-c. That way, your shellscript - +including any loops - would continue and you had no chance of aborting +it except using the kill command after finding out the outermost +shell's PID. This "solution" will not be discussed further, as it is +obviously not desirable. + +

  • The shell itself exits immediately when it receives SIGINT. Not +only the program called will exit, but the calling (the +script-executing) shell. The first variant is to exit the shell (and +therefore discontinuing execution of the script) immediately, while +the background program may still be executing (remember that although +the shell is just waiting for the called program to exit, it is woken +up and may act). I will call the way of doing things the "IUE" (for +"immediate unconditional exit") for the rest of this document. + +

  • As a variant of the former, when the shell receives SIGINT +while it is waiting for a child to exit, the shell does not exit +immediately. but it remembers the fact that a SIGINT happened. After +the called program exits and the shell's wait ends, the shell will +exit itself and hence discontinue the script. I will call the way of +doing things the "WUE" (for "wait and unconditional exit") for the +rest of this document. + +

  • There is also a way that the calling shell can tell whether the +called program exited on SIGINT and if it ignored SIGINT (or used it +for other purposes). As in the WUE way, the shell waits for +the child to complete. It figures whether the program was ended on +SIGINT and if so, it discontinue the script. If the program did any +other exit, the script will be continued. I will call the way of doing +things the "WCE" (for "wait and cooperative exit") for the rest of +this document. + +
    •  + +

    The problem

    + +On first sight, all three solutions (IUE, WUE and WCE) all seem to do +what we want: If C-c is hit while the first program of the shell +script runs, the script is discontinued. The user gets his prompt back +immediately. So what are the difference between these way of handling +SIGINT? + +

    There are programs that use the signal SIGINT for other purposes +than exiting. They use it as a normal keystroke. The user is expected +to use the key that sends SIGINT during a perfectly normal program +run. As a result, the user sends SIGINT in situations where he/she +does not want the program or the script to end. + +

    The primary example is the emacs editor: C-g does what ESC does in +other applications: It cancels a partially executed or prepared +operation. Technically, emacs remaps the key that sends SIGINT from +C-c to C-g and catches SIGINT. + +

    Remember that the SIGINT is sent to all programs running in the +foreground. If emacs is executing from a shell script, both emacs and +the shell get SIGINT. emacs is the program that decides what to do: +Exit on SIGINT or not. emacs decides not to exit. The problem arises +when the shell draws its own conclusions from receiving SIGINT without +consulting emacs for its opinion. + +

    Consider this script: +

    +#! /bin/sh
+emacs /tmp/foo
+cp /tmp/foo /home/user/mail/sent
+
    + +

    If C-g is used in emacs, both the shell and emacs will received +SIGINT. Emacs will not exit, the user used C-g as a normal editing +keystroke, he/she does not want the script to be aborted on C-g. + +

    The central problem is that the second command (cp) may +unintentionally be killed when the shell draws its own conclusion +about the user's intention. The innermost program is the only one to +judge. + +

    One more example

    + +

    Imagine a mail session using a curses mailer in a tty. You called +your mailer and started to compose a message. Your mailer calls emacs. +C-g is a normal editing key in emacs. Technically it +sends SIGINT (it was C-c, but emacs remapped the key) to +

    +
  • emacs +
  • the shell between your mailer and emacs, the one from your mailers + system("emacs /tmp/bla.44") command +
  • the mailer itself +
  • possibly another shell if your mailer was called by a shell script +or from another application using system(3) +
  • your interactive shell (which ignores it since it is interactive +and hence is not relevant to this discussion) +
    •  + +

    If everyone just exits on SIGINT, you will be left with nothing but +your login shell, without asking. + +

    But for sure you don't want to be dropped out of your editor and +out of your mailer back to the commandline, having your edited data +and mailer status deleted. + +

    Understand the difference: While C-g is used an a kind +of abort key in emacs, it isn't the major "abort everything" key. When +you use C-g in emacs, you want to end some internal emacs +command. You don't want your whole emacs and mailer session to end. + +

    So, if the shell exits immediately if the user sends SIGINT (the +second of the four ways shown above), the parent of emacs would die, +leaving emacs without the controlling tty. The user will lose it's +editing session immediately and unrecoverable. If the "main" shell of +the operating system defaults to this behavior, every editor session +that is spawned from a mailer or such will break (because it is +usually executed by system(3), which calls /bin/sh). This was the case +in FreeBSD before I and Bruce Evans changed it in 1998. + +

    If the shell recognized that SIGINT was sent and exits after the +current foreground process exited (the third way of the four), the +editor session will not be disturbed, but things will still not work +right. + +

    A further look at the alternatives

    + +

    Still considering this script to examine the shell's actions in the +IUE, WUE and ICE way of handling SIGINT: +

    +#! /bin/sh
+emacs /tmp/foo
+cp /tmp/foo /home/user/mail/sent
+
    + +

    The IUE ("immediate unconditional exit") way does not work at all: +emacs wants to survive the SIGINT (it's a normal editing key for +emacs), but its parent shell unconditionally thinks "We received +SIGINT. Abort everything. Now.". The shell will exit even before emacs +exits. But this will leave emacs in an unusable state, since the death +of its calling shell will leave it without required resources (file +descriptors). This way does not work at all for shellscripts that call +programs that use SIGINT for other purposes than immediate exit. Even +for programs that exit on SIGINT, but want to do some cleanup between +the signal and the exit, may fail before they complete their cleanup. + +

    It should be noted that this way has one advantage: If a child +blocks SIGINT and does not exit at all, this way will get control back +to the user's terminal. Since such programs should be banned from your +system anyway, I don't think that weighs against the disadvantages. + +

    WUE ("wait and unconditional exit") is a little more clever: If C-g +was used in emacs, the shell will get SIGINT. It will not immediately +exit, but remember the fact that a SIGINT happened. When emacs ends +(maybe a long time after the SIGINT), it will say "Ok, a SIGINT +happened sometime while the child was executing, the user wants the +script to be discontinued". It will then exit. The cp will not be +executed. But that's bad. The "cp" will be executed when the emacs +session ended without the C-g key ever used, but it will not be +executed when the user used C-g at least one time. That is clearly not +desired. Since C-g is a normal editing key in emacs, the user expects +the rest of the script to behave identically no matter what keys he +used. + +

    As a result, the "WUE" way is better than the "IUE" way in that it +does not break SIGINT-using programs completely. The emacs session +will end undisturbed. But it still does not support scripts where +other actions should be performed after a program that use SIGINT for +non-exit purposes. Since the behavior is basically undeterminable for +the user, this can lead to nasty surprises. + +

    The "WCE" way fixes this by "asking" the called program whether it +exited on SIGINT or not. While emacs receives SIGINT, it does not exit +on it and a calling shell waiting for its exit will not be told that +it exited on SIGINT. (Although it receives SIGINT at some point in +time, the system does not enforce that emacs will exit with +"I-exited-on-SIGINT" status. This is under emacs' control, see below). + +

    this still work for the normal script without SIGINT-using +programs:

    +
    +#! /bin/sh
+program1
+program2
+
    + +Unless program1 and program2 mess around with signal handling, the +system will tell the calling shell whether the programs exited +normally or as a result of SIGINT. + +

    The "WCE" way then has an easy way to things right: When one called +program exited with "I-exited-on-SIGINT" status, it will discontinue +the script after this program. If the program ends without this +status, the next command in the script is started. + +

    It is important to understand that a shell in "WCE" modus does not +need to listen to the SIGINT signal at all. Both in the +"emacs-then-cp" script and in the "several-normal-programs" script, it +will be woken up and receive SIGINT when the user hits the +corresponding key. But the shell does not need to react on this event +and it doesn't need to remember the event of any SIGINT, either. +Telling whether the user wants to end a script is done by asking that +program that has to decide, that program that interprets keystrokes +from the user, the innermost program. + +

    So everything is well with WCE?

    + +Well, almost. + +

    The problem with the "WCE" modus is that there are broken programs +that do not properly communicate the required information up to the +calling program. + +

    Unless a program messes with signal handling, the system does this +automatically. + +

    There are programs that want to exit on SIGINT, but they don't let +the system do the automatic exit, because they want to do some +cleanup. To do so, they catch SIGINT, do the cleanup and then exit by +themselves. + +

    And here is where the problem arises: Once they catch the signal, +the system will no longer communicate the "I-exited-on-SIGINT" status +to the calling program automatically. Even if the program exit +immediately in the signal handler of SIGINT. Once it catches the +signal, it has to take care of communicating the signal status +itself. + +

    Some programs don't do this. On SIGINT, they do cleanup and exit +immediately, but the calling shell isn't told about the non-normal exit +and it will call the next program in the script. + +

    As a result, the user hits SIGINT and while one program exits, the +shellscript continues. To him/her it looks like the shell fails to +obey to his abortion command. + +

    Both IUE or WUE shell would not have this problem, since they +discontinue the script on their own. But as I said, they don't support +programs using SIGINT for non-exiting purposes, no matter whether +these programs properly communicate their signal status to the calling +shell or not. + +

    Since some shell in wide use implement the WUE way (and some even +IUE), there is a considerable number of broken programs out there that +break WCE shells. The programmers just don't recognize it if their +shell isn't WCE. + +

    How to be a proper program

    + +

    (Short note in advance: What you need to achieve is that +WIFSIGNALED(status) is true in the calling program and that +WTERMSIG(status) returns SIGINT.) + +

    If you don't catch SIGINT, the system automatically does the right +thing for you: Your program exits and the calling program gets the +right "I-exited-on-SIGINT" status after waiting for your exit. + +

    But once you catch SIGINT, you have to act. + +

    Decide whether the SIGINT is used for exit/abort purposes and hence +a shellscript calling this program should discontinue. This is +hopefully obvious. If you just need to do some cleanup on SIGINT, but +then exit immediately, the answer is "yes". + +

    If so, you have to tell the calling program about it by exiting +with the "I-exited-on-SIGINT" status. + +

    There is no other way of doing this than to kill yourself with a +SIGINT signal. Do it by resetting the SIGINT handler to SIG_DFL, then +send yourself the signal. + +

    +void sigint_handler(int sig)
+{
+	
+	signal(SIGINT, SIG_DFL);
+	kill(getpid(), SIGINT);
+}
+
    + +Notes: + + + +
  • You cannot "fake" the proper exit status by an exit(3) with a +special numeric value. People often assume this since the manuals for +shells often list some return value for exactly this. But this is just +a convention for your shell script. It does not work from one UNIX API +program to another. + +

    All that happens is that the shell sets the "$?" variable to a +special numeric value for the convenience of your script, because your +script does not have access to the lower-lever UNIX status evaluation +functions. This is just an agreement between your script and the +executing shell, it does not have any meaning in other contexts. + +

  • Do not use kill(0, SIGINT) without consulting the manul for +your OS implementation. I.e. on BSD, this would not send the signal to +the current process, but to all processes in the group. + +

  • POSIX 1003.1 allows all these calls to appear in signal +handlers, so it is portable. + +
    •  + +

    In a bourne shell script, you can catch signals using the +trap command. Here, the same as for C programs apply. If +the intention of SIGINT is to end your program, you have to exit in a +way that the calling programs "sees" that you have been killed. If +you don't catch SIGINT, this happened automatically, but of you catch +SIGINT, i.e. to do cleanup work, you have to end the program by +killing yourself, not by calling exit. + +

    Consider this example from FreeBSD's mkdep, which is a +bourne shell script. + +

    +TMP=_mkdep$$
+trap 'rm -f $TMP ; trap 2 ; kill -2 $$' 1 2 3 13 15
+
    + +Yes, you have to do it the hard way. It's even more annoying in shell +scripts than in C programs since you can't "pre-delete" temporary +files (which isn't really portable in C, though). + +

    All this applies to programs in all languages, not only C and +bourne shell. Every language implementation that lets you catch SIGINT +should also give you the option to reset the signal and kill yourself. + +

    It is always desirable to exit the right way, even if you don't +expect your usual callers to depend on it, some unusual one will come +along. This proper exit status will be needed for WCE and will not +hurt when the calling shell uses IUE or WUE. + +

    How to be a proper shell

    + +All this applies only for the script-executing case. Most shells will +also have interactive modes where things are different. + + + +
  • Do nothing special when SIGINT appears while you wait for a child. +You don't even have to remember that one happened. + +

  • Wait for child to exit, get the exit status. Do not truncate it +to type char. + +

  • Look at WIFSIGNALED(status) and WTERMSIG(status) to tell +whether the child says "I exited on SIGINT: in my opinion the user +wants the shellscript to be discontinued". + +

  • If the latter applies, discontinue the script. + +

  • Exit. But since a shellscript may in turn be called by a +shellscript, you need to make sure that you properly communicate the +discontinue intention to the calling program. As in any other program +(see above), do + +
    +	signal(SIGINT, SIG_DFL);
+	kill(getpid(), SIGINT);
+
    + +
    •  + +

    Other remarks

    + +Although this web page talks about SIGINT only, almost the same issues +apply to SIGQUIT, including proper exiting by killing yourself after +catching the signal and proper reaction on the WIFSIGNALED(status) +value. One notable difference for SIGQUIT is that you have to make +sure that not the whole call tree dumps core. + +

    What to fight

    + +Make sure all programs really kill themselves if they react +to SIGINT or SIGQUIT and intend to abort their operation as a result +of this signal. Programs that don't use SIGINT/SIGQUIT as a +termination trigger - but as part of normal operation - don't kill +themselves, but do a normal exit instead. + +

    Make sure people understand why you can't fake an exit-on-signal by +doing exit(...) using any numerical status. + +

    Make sure you use a shell that behaves right. Especially if you +develop programs, since it will help seeing problems. + +

    Concrete examples how to fix programs:

    +
      + +
    • The fix for FreeBSD's +time(1). This fix is the best example, it's quite short and clear and +it fixes a case where someone tried to fake signal exit status by a +numerical value. And the complete program is small. + +

    • Fix for FreeBSD's +truss(1). + +

    • The fix for FreeBSD's +mkdep(1), a shell script. + + +

    • Fix for FreeBSD's make(1), part 1, +part 2. + +
    + +

    Testsuite for shells

    + +I have a collection of shellscripts that test shells for the +behavior. See my download dir to get the newest +"sh-interrupt" files, either as a tarfile or as individual file for +online browsing. This isn't really documented, besides from the +comments the scripts echo. + +

If you are the maintainer of a file that does +not follow these guidelines, please -- at your own convenience -- modify the +file(s) you maintain to bring them into conformance with this style guide. +Please note that this is a low priority task. + +To help you format the whitespace of your programs, an ".indent.pro" file is +included in the main Busybox source directory that contains option flags to +format code as per this style guide.

Do not indent lines +with spaces and do not indents lines using a mixture of tabs and spaces. (The +indentation style in the Apache and Postfix source does this sort of thing: +\s\s\s\sif (expr) {\n\tstmt; --ick.) The only exception to this rule is +multi-line comments that use an asterisk at the beginning of each line, i.e.: + + \t/* + \t * This is a block comment. + \t * Note that it has multiple lines + \t * and that the beginning of each line has a tab plus a space + \t * except for the opening '/*' line where the slash + \t * is used instead of a space. + \t */ + +Furthermore, The preference is that tabs be set to display at four spaces +wide, but the beauty of using only tabs (and not spaces) at the beginning of +lines is that you can set your editor to display tabs at *whatever* number of +spaces is desired and the code will still look fine. + + +Operator Spacing +~~~~~~~~~~~~~~~~ + +Put spaces between terms and operators. Example: + + Don't do this: + + for(i=0;i 0) + + +Bracket Spacing +~~~~~~~~~~~~~~~ + +If an opening bracket starts a function, it should be on the +next line with no spacing before it. However, if a bracket follows an opening +control block, it should be on the same line with a single space (not a tab) +between it and the opening control block statement. Examples: + + Don't do this: + + while (!done) + { + + do + { + + Don't do this either: + + while (!done){ + + do{ + + And for heaven's sake, don't do this: + + while (!done) + { + + do + { + + Do this instead: + + while (!done) { + + do { + +If you have long logic statements that need to be wrapped, then uncuddling +the bracket to improve readability is allowed. Generally, this style makes +it easier for reader to notice that 2nd and following lines are still +inside 'if': + + if (some_really_long_checks && some_other_really_long_checks + && some_more_really_long_checks + && even_more_of_long_checks + ) { + do_foo_now; + +Spacing around Parentheses +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Put a space between C keywords and left parens, but not between function names +and the left paren that starts it's parameter list (whether it is being +declared or called). Examples: + + Don't do this: + + while(foo) { + for(i = 0; i < n; i++) { + + Do this instead: + + while (foo) { + for (i = 0; i < n; i++) { + + But do functions like this: + + static int my_func(int foo, char bar) + ... + baz = my_func(1, 2); + +Also, don't put a space between the left paren and the first term, nor between +the last arg and the right paren. + + Don't do this: + + if ( x < 1 ) + strcmp( thisstr, thatstr ) + + Do this instead: + + if (x < 1) + strcmp(thisstr, thatstr) + + +Cuddled Elses +~~~~~~~~~~~~~ + +Also, please "cuddle" your else statements by putting the else keyword on the +same line after the right bracket that closes an 'if' statement. + + Don't do this: + + if (foo) { + stmt; + } + else { + stmt; + } + + Do this instead: + + if (foo) { + stmt; + } else { + stmt; + } + +The exception to this rule is if you want to include a comment before the else +block. Example: + + if (foo) { + stmts... + } + /* otherwise, we're just kidding ourselves, so re-frob the input */ + else { + other_stmts... + } + + +Labels +~~~~~~ + +Labels should start at the beginning of the line, not indented to the block +level (because they do not "belong" to block scope, only to whole function). + + if (foo) { + stmt; + label: + stmt2; + stmt; + } + +(Putting label at position 1 prevents diff -p from confusing label for function +name, but it's not a policy of busybox project to enforce such a minor detail). + + + +Variable and Function Names +--------------------------- + +Use the K&R style with names in all lower-case and underscores occasionally +used to separate words (e.g., "variable_name" and "numchars" are both +acceptable). Using underscores makes variable and function names more readable +because it looks like whitespace; using lower-case is easy on the eyes. + + Frowned upon: + + hitList + TotalChars + szFileName + pf_Nfol_TriState + + Preferred: + + hit_list + total_chars + file_name + sensible_name + +Exceptions: + + - Enums, macros, and constant variables are occasionally written in all + upper-case with words optionally separated by underscores (i.e. FIFO_TYPE, + ISBLKDEV()). + + - Nobody is going to get mad at you for using 'pvar' as the name of a + variable that is a pointer to 'var'. + + +Converting to K&R +~~~~~~~~~~~~~~~~~ + +The Busybox codebase is very much a mixture of code gathered from a variety of +sources. This explains why the current codebase contains such a hodge-podge of +different naming styles (Java, Pascal, K&R, just-plain-weird, etc.). The K&R +guideline explained above should therefore be used on new files that are added +to the repository. Furthermore, the maintainer of an existing file that uses +alternate naming conventions should, at his own convenience, convert those +names over to K&R style. Converting variable names is a very low priority +task. + +If you want to do a search-and-replace of a single variable name in different +files, you can do the following in the busybox directory: + + $ perl -pi -e 's/\bOldVar\b/new_var/g' *.[ch] + +If you want to convert all the non-K&R vars in your file all at once, follow +these steps: + + - In the busybox directory type 'examples/mk2knr.pl files-to-convert'. This + does not do the actual conversion, rather, it generates a script called + 'convertme.pl' that shows what will be converted, giving you a chance to + review the changes beforehand. + + - Review the 'convertme.pl' script that gets generated in the busybox + directory and remove / edit any of the substitutions in there. Please + especially check for false positives (strings that should not be + converted). + + - Type './convertme.pl same-files-as-before' to perform the actual + conversion. + + - Compile and see if everything still works. + +Please be aware of changes that have cascading effects into other files. For +example, if you're changing the name of something in, say utility.c, you +should probably run 'examples/mk2knr.pl utility.c' at first, but when you run +the 'convertme.pl' script you should run it on _all_ files like so: +'./convertme.pl *.[ch]'. + + + +Avoid The Preprocessor +---------------------- + +At best, the preprocessor is a necessary evil, helping us account for platform +and architecture differences. Using the preprocessor unnecessarily is just +plain evil. + + +The Folly of #define +~~~~~~~~~~~~~~~~~~~~ + +Use 'const var' for declaring constants. + + Don't do this: + + #define CONST 80 + + Do this instead, when the variable is in a header file and will be used in + several source files: + + enum { CONST = 80 }; + +Although enum may look ugly to some people, it is better for code size. +With "const int" compiler may fail to optimize it out and will reserve +a real storage in rodata for it! (Hopefully, newer gcc will get better +at it...). With "define", you have slight risk of polluting namespace +(#define doesn't allow you to redefine the name in the inner scopes), +and complex "define" are evaluated each time they used, not once +at declarations like enums. Also, the preprocessor does _no_ type checking +whatsoever, making it much more error prone. + + +The Folly of Macros +~~~~~~~~~~~~~~~~~~~ + +Use 'static inline' instead of a macro. + + Don't do this: + + #define mini_func(param1, param2) (param1 << param2) + + Do this instead: + + static inline int mini_func(int param1, param2) + { + return (param1 << param2); + } + +Static inline functions are greatly preferred over macros. They provide type +safety, have no length limitations, no formatting limitations, have an actual +return value, and under gcc they are as cheap as macros. Besides, really long +macros with backslashes at the end of each line are ugly as sin. + + +The Folly of #ifdef +~~~~~~~~~~~~~~~~~~~ + +Code cluttered with ifdefs is difficult to read and maintain. Don't do it. +Instead, put your ifdefs at the top of your .c file (or in a header), and +conditionally define 'static inline' functions, (or *maybe* macros), which are +used in the code. + + Don't do this: + + ret = my_func(bar, baz); + if (!ret) + return -1; + #ifdef CONFIG_FEATURE_FUNKY + maybe_do_funky_stuff(bar, baz); + #endif + + Do this instead: + + (in .h header file) + + #if ENABLE_FEATURE_FUNKY + static inline void maybe_do_funky_stuff(int bar, int baz) + { + /* lotsa code in here */ + } + #else + static inline void maybe_do_funky_stuff(int bar, int baz) {} + #endif + + (in the .c source file) + + ret = my_func(bar, baz); + if (!ret) + return -1; + maybe_do_funky_stuff(bar, baz); + +The great thing about this approach is that the compiler will optimize away +the "no-op" case (the empty function) when the feature is turned off. + +Note also the use of the word 'maybe' in the function name to indicate +conditional execution. + + + +Notes on Strings +---------------- + +Strings in C can get a little thorny. Here's some guidelines for dealing with +strings in Busybox. (There is surely more that could be added to this +section.) + + +String Files +~~~~~~~~~~~~ + +Put all help/usage messages in usage.c. Put other strings in messages.c. +Putting these strings into their own file is a calculated decision designed to +confine spelling errors to a single place and aid internationalization +efforts, if needed. (Side Note: we might want to use a single file - maybe +called 'strings.c' - instead of two, food for thought). + + +Testing String Equivalence +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There's a right way and a wrong way to test for string equivalence with +strcmp(): + + The wrong way: + + if (!strcmp(string, "foo")) { + ... + + The right way: + + if (strcmp(string, "foo") == 0){ + ... + +The use of the "equals" (==) operator in the latter example makes it much more +obvious that you are testing for equivalence. The former example with the +"not" (!) operator makes it look like you are testing for an error. In a more +perfect world, we would have a streq() function in the string library, but +that ain't the world we're living in. + + +Avoid Dangerous String Functions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Unfortunately, the way C handles strings makes them prone to overruns when +certain library functions are (mis)used. The following table offers a summary +of some of the more notorious troublemakers: + +function overflows preferred +------------------------------------------------- +strcpy dest string safe_strncpy +strncpy may fail to 0-terminate dst safe_strncpy +strcat dest string strncat +gets string it gets fgets +getwd buf string getcwd +[v]sprintf str buffer [v]snprintf +realpath path buffer use with pathconf +[vf]scanf its arguments just avoid it + + +The above is by no means a complete list. Be careful out there. + + + +Avoid Big Static Buffers +------------------------ + +First, some background to put this discussion in context: static buffers look +like this in code: + + /* in a .c file outside any functions */ + static char buffer[BUFSIZ]; /* happily used by any function in this file, + but ick! big! */ + +The problem with these is that any time any busybox app is run, you pay a +memory penalty for this buffer, even if the applet that uses said buffer is +not run. This can be fixed, thusly: + + static char *buffer; + ... + other_func() + { + strcpy(buffer, lotsa_chars); /* happily uses global *buffer */ + ... + foo_main() + { + buffer = xmalloc(sizeof(char)*BUFSIZ); + ... + +However, this approach trades bss segment for text segment. Rather than +mallocing the buffers (and thus growing the text size), buffers can be +declared on the stack in the *_main() function and made available globally by +assigning them to a global pointer thusly: + + static char *pbuffer; + ... + other_func() + { + strcpy(pbuffer, lotsa_chars); /* happily uses global *pbuffer */ + ... + foo_main() + { + char *buffer[BUFSIZ]; /* declared locally, on stack */ + pbuffer = buffer; /* but available globally */ + ... + +This last approach has some advantages (low code size, space not used until +it's needed), but can be a problem in some low resource machines that have +very limited stack space (e.g., uCLinux). + +A macro is declared in busybox.h that implements compile-time selection +between xmalloc() and stack creation, so you can code the line in question as + + RESERVE_CONFIG_BUFFER(buffer, BUFSIZ); + +and the right thing will happen, based on your configuration. + +Another relatively new trick of similar nature is explained +in keep_data_small.txt. + + + +Miscellaneous Coding Guidelines +------------------------------- + +The following are important items that don't fit into any of the above +sections. + + +Model Busybox Applets After GNU Counterparts +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +When in doubt about the proper behavior of a Busybox program (output, +formatting, options, etc.), model it after the equivalent GNU program. +Doesn't matter how that program behaves on some other flavor of *NIX; doesn't +matter what the POSIX standard says or doesn't say, just model Busybox +programs after their GNU counterparts and it will make life easier on (nearly) +everyone. + +The only time we deviate from emulating the GNU behavior is when: + + - We are deliberately not supporting a feature (such as a command line + switch) + - Emulating the GNU behavior is prohibitively expensive (lots more code + would be required, lots more memory would be used, etc.) + - The difference is minor or cosmetic + +A note on the 'cosmetic' case: output differences might be considered +cosmetic, but if the output is significant enough to break other scripts that +use the output, it should really be fixed. + + +Scope +~~~~~ + +If a const variable is used only in a single source file, put it in the source +file and not in a header file. Likewise, if a const variable is used in only +one function, do not make it global to the file. Instead, declare it inside +the function body. Bottom line: Make a conscious effort to limit declarations +to the smallest scope possible. + +Inside applet files, all functions should be declared static so as to keep the +global name space clean. The only exception to this rule is the "applet_main" +function which must be declared extern. + +If you write a function that performs a task that could be useful outside the +immediate file, turn it into a general-purpose function with no ties to any +applet and put it in the utility.c file instead. + + +Brackets Are Your Friends +~~~~~~~~~~~~~~~~~~~~~~~~~ + +Please use brackets on all if and else statements, even if it is only one +line. Example: + + Don't do this: + + if (foo) + stmt1; + stmt2 + stmt3; + + Do this instead: + + if (foo) { + stmt1; + } + stmt2 + stmt3; + +The "bracketless" approach is error prone because someday you might add a line +like this: + + if (foo) + stmt1; + new_line(); + stmt2; + stmt3; + +And the resulting behavior of your program would totally bewilder you. (Don't +laugh, it happens to us all.) Remember folks, this is C, not Python. + + +Function Declarations +~~~~~~~~~~~~~~~~~~~~~ + +Do not use old-style function declarations that declare variable types between +the parameter list and opening bracket.

To our good fortune, we have access +to more modern compilers and the old declaration syntax is neither necessary +nor desired. + + +Emphasizing Logical Blocks +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Organization and readability are improved by putting extra newlines around +blocks of code that perform a single task. These are typically blocks that +begin with a C keyword, but not always. + +Furthermore, you should put a single comment (not necessarily one line, just +one comment) before the block, rather than commenting each and every line. +There is an optimal amount of commenting that a program can have; you can +comment too much as well as too little. + +A picture is really worth a thousand words here, the following example +illustrates how to emphasize logical blocks: + + while (line = xmalloc_fgets(fp)) { + + /* eat the newline, if any */ + chomp(line); + + /* ignore blank lines */ + if (strlen(file_to_act_on) == 0) { + continue; + } + + /* if the search string is in this line, print it, + * unless we were told to be quiet */ + if (strstr(line, search) && !be_quiet) { + puts(line); + } + + /* clean up */ + free(line); + } + + +Processing Options with getopt +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If your applet needs to process command-line switches, please use getopt32() to +do so. Numerous examples can be seen in many of the existing applets, but +basically it boils down to two things: at the top of the .c file, have this +line in the midst of your #includes, if you need to parse long options: + + #include + +Then have long options defined: + + static const char _longopts[] ALIGN1 = + "list\0" No_argument "t" + "extract\0" No_argument "x" + ; + +And a code block similar to the following near the top of your applet_main() +routine: + + char *str_b; + + opt_complementary = "cryptic_string"; + applet_long_options = _longopts; /* if you have them */ + opt = getopt32(argc, argv, "ab:c", &str_b); + if (opt & 1) { + handle_option_a(); + } + if (opt & 2) { + handle_option_b(str_b); + } + if (opt & 4) { + handle_option_c(); + } + +If your applet takes no options (such as 'init'), there should be a line +somewhere in the file reads: + + /* no options, no getopt */ + +That way, when people go grepping to see which applets need to be converted to +use getopt, they won't get false positives. + +For more info and examples, examine getopt32.c, tar.c, wget.c etc. diff --git a/busybox-1.37.0/docs/syslog.conf.txt b/busybox-1.37.0/docs/syslog.conf.txt new file mode 100644 index 00000000000..6d9c4a173a6 --- /dev/null +++ b/busybox-1.37.0/docs/syslog.conf.txt @@ -0,0 +1,28 @@ +If syslogd applet compiled with FEATURE_SYSLOGD_CFG=y, then it supports restricted syslog.conf. +The config resembles rsyslog.conf in RULES part: + +LINE = DELIM [RULE | COMMENT] +COMMENT = #.* +DELIM = SPACE TAB +RULE = SELECTOR [;SELECTOR]* DELIM* ACTION DELIM* +SELECTOR = FACILITY [,FACILITY]* .[[!]=] PRIORITY +FACILITY = * | kern | user ...

+=========================== + +This document describes what you need to do to write test cases using the +Busybox unit test framework. + + +Building unit tests +------------------- + +The framework

testing interface can be found in include/bbunit.h. + +Tests can be placed in any .c file in Busybox tree - preferably right next to +the functions they test. Test cases should be enclosed within an #if, and +should start with BBUNIT_DEFINE_TEST macro and end with BBUNIT_ENDTEST within +the test curly brackets. If an assertion fails the test ends immediately, ie. +the following assertions will not be reached. Any code placed after +BBUNIT_ENDTEST is executed regardless of the test result.
