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 + + Appendix: 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. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) 19yy <name of author> + + 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., 675 Mass Ave, Cambridge, MA 02139, 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) 19yy 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. + + <signature of Ty Coon>, 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/COPYING.UCB b/COPYING.UCB new file mode 100644 index 00000000..9abbf241 --- /dev/null +++ b/COPYING.UCB @@ -0,0 +1,32 @@ +/* + * Copyright (c) 1989 The Regents of the University of California. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

Trying to comply with the draft file system standard was too + much of a headache when these utilities were all in different pacakges. + +1) The clock program from the timesrc-1.2.tar.Z package is included. The + rest of this distribution has been replaced by the ado@elsie.nci.nih.gov + version. See below for details. + + Patches from Hamish Coleman (hamish@zot.apana.org.au) have been applied + to the clock program, making it version 1.2a. See clock.c for details. + These patches "stuff things up" if your cmos clock is not in universal + time, so they have been removed. + + Version 1.3 is updates from Alan Modra (alan@spri.levels.unisa.edu.au). + These were also reverted because they break if your cmos clock is not in + universal time. Version 1.3 source is in the broken subdirectory in + case anyone wants to fix this. + +2) The time directory contains tzcode94e.tar.gz and tzdata94d.tar.gz from + elsie.nci.nih.gov. + +3) Peter Orbaek (poe@daimi.aau.dk) put together the admutil-1.11.tar.gz + package.

These were forwarded to Peter. + +5) Jim Winstead Jr. (jwinstea@fenris.claremont.edu) put together the + system-0.98.tar.Z package. The following are from that collection: + + doshell (by Jim Wiegand, + with modifications by Marcel Mol (marcel@dutecad.et.tudelft.nl)) + + fdformat (by Werner Almesberger (almesber@nessie.cs.id.ethz.ch), + with modifications by Marcel Mol (marcel@dutecad.et.tudelft.nl)) + -- Actually, updated with a September 1992 version by Werner. + + frag (by Werner Almesberger (V1.0), with modifications + by Steffen Zahn (V1.1), + by Rob Hooft (V1.2), + and by Steffen Zahn (szahn%masterix@emndev.siemens.co.at)) + + setfdprm (by Werner Almesberger (almesber@nessie.cs.id.ethz.ch)) + + sync (by Nick Holloway, with thanks to James Bonfield) -- a small, + assembly language version replaces the old C language version by + Linus Torvalds (torvalds@cs.helsinki.fi) + + ed.old (by Brian Beattie, Kees Bot, and others; with changes by + W.

The following are from that package (all + appear to be by Doug Quale (quale@saavik.cs.wisc.edu), with + modifications by H. J. Lu (hlu@eecs.wsu.edu) on 11/25/92; Rick Sladkey + (jrs@world.std.com) in January 1993; and Stephen Tweedie + <sct@dcs.ed.ac.uk> on 8 October 1993: + + mount + umount + swapon + + This distribution mount now supports NFS stuff. I have modified the man + pages. I have also added a small patch from Hamish Glen Coleman + (t933093@minyos.xx.rmit.OZ.AU) which restores the -o semantics. + + Updated with Rick Sladkey's mount-0.99.14.tar.gz package, and with + extra patches from Rick. + + Adam J. Richter allowed -t option to be optional. + + Patrick J. Volkerding (volkerdi@mhd1.moorhead.msus.edu) and Mitchum + DSouza both provided patches that fixed the (null) problem when not + using -t. + + Mitchum DSouza (mitch@mrc-applied-psychology.cambridge.ac.uk) added + support for loop device mounts. + + Sebastian Lederer (lederer@next-pc.informatik.uni-bonn.de) added + support for sending an unmount RPC call to the server when an + NFS-filesystem is unmounted. + + Sander van Malssen (svm@kozmix.hacktic.nl) added support for remounting + readonly file systems readonly. + +7) The rdev program is original work by Werner Almesberger + (almesber@nessie.cs.id.ethz.ch), modified by Peter MacDonald and Stephen + Tweedie. + +8) I (Rik Faith) wrote: + + kbdrate + clear + reset (updated to call 'stty sane' first) + look + + most of the man pages + +9) Linus Torvalds (torvalds@cs.helsinki.fi) released new versions of + fsck.c, mkfs.c, and mkswap.c in February 1993. This fsck and mkfs + support 14 *and* 30 character minux filesystems! + + fsck HAS BEEN RENAMED TO fsck.minix! TAKE NOTE! This change is for + compatibility with the fsutil package. The return codes have also been + fixed for compatibility with the fsutil package. + + fsck.minix and mkfs.minix have been updated by Rik Faith + (faith@cs.unc.edu), Scott Heavner (sdh@po.cwru.edu), and Dr. Wettstein + (greg%wind.uucp@plains.nodak.edu). + +10) David Engel (david@ods.com) put together the fsutil-1.8.tar.gz package, + which contains a generic front-end for fsck and mkfs. This package has + been included in this release. He also did lfconfig, which is from his + ldso-1.3.tar.z package. + +11) Michael K. Johnson (johnsonm@stolaf.edu) re-released Rick Sladkey's + setserial in January 1993, with changes by Theodore Ts'o + (tytso@mit.edu). I think that Theodore also did extensive changes for + version 2.01, I can't find any notes about this in the documentation. + However, Theodore Ts'o (tytso@ATHENA.MIT.EDU) released version 2.10, + and that is now included. + +12) I applied enhancments and bug fixes to the fdisk (by A. V. Le Blanc + (LeBlanc@mcc.ac.uk)) in Jim Winstead Jr.'s + (jwinstea@fenris.claremont.edu) system-0.98.tar.Z package. Owen + (LeBlanc) then re-enhanced the version and added bug fixes. He also + gave me a copy of the excellent documentation: see README.fdisk. I + have replaced this old version with Owen's fdisk 1.5 release, with + Kevin Martin's patches for DOS and OS/2 compatibility. I've called + this version 1.5a. Then I changed a few partition names, and called it + 1.5b. Since Kevin's changes were significant, it should probably have + been called 1.6. . . + +13) Added ipcs and ipcrm from the ipcdelta.tar.z distribution by krishna + balasub@cis.ohio-state.edu on 3/15/93. I also took the ipc.info and + ipc.texi files from that distribution. I wrote short man pages for the + binaries. + +14) The new dmesg program from Theodore Ts'o is also included, with a man + page that I wrote, and changes from Rick Sladkey. + +15) The complete selection-1.5 package, by Andrew Haylett + <ajh@gec-mrc.co.uk>, 17th June 1993, is included. Kernel patches are + no longer necessary for modern kernels, but these were tiny so I left + them in for historical reasons. The Makefile was modified for this + distribution. With changes from Rick Sladkey. + +16) A posix-compliant ed is now in ed.posix, and is used by default. See + the README and source for authorship information and other credits, + including The Regents of the University of California; Rodney Ruddock + of the University of Guelph, Guelph, Ontario; Matt Bishop of Dartmouth + College, Hanover, NH; and Addison-Wesley Publishing Company. The code + is based on B. W. Kernighan and P. J. Plauger, SOFTWARE TOOLS IN + PASCAL, Addison-Wesley, 1981. + +17) Gordon Irlam (gordoni@cs.ua.oz.au) did setterm, which was adapted to + Linux by Peter MacDonald and enhanced by Mika Liljeberg + (liljeber@cs.Helsinki.FI). A bunch of patches from John Walder + (j-walder@uiuc.edu) were applied so that setterm will work with dosemu. + +18) Several utilities are from the BSD NET-2 (4.3bsd-reno) distribution: + + col (5.3 (Berkeley) 2/2/91) + [See README.col for comments, and differences other cols] + hexdump (5.5 (Berkeley) 6/1/90) + rev (5.2 (Berkeley) 3/21/92, with modifications for Linux by + Charles Hannum (mycroft@gnu.ai.mit.edu) and Brian + Koehmstedt (bpk@gnu.ai.mit.edu)) + strings (5.10 (Berkeley) 5/23/91) + syslogd (5.45 (Berkeley) 3/2/91) [with ttymsg; see below for changes] + tsort (5.3 (Berkeley) 6/1/90) + wall (5.14 (Berkeley) 3/2/91) + whereis (5.5 (Berkeley) 4/18/91) + write (4.22 (Berkeley) 6/1/90) + + Most of the changes for syslogd come from Rick Sladkey + (jrs@world.std.com), but I'd like to thank other people who sent in + changes (which usually got forwarded to Rick): Carsten Paeth + (calle@calle.in-berlin.de) and Kaz Sasayama (kaz@lilia.iijnet.or.jp). + + Original NET-2 source is currently available at + wuarchive.wustl.edu:/mirrors/4.3-reno/{bin,usr.bin}. The only changes + that where made to these sources were that more reasonable paths were + placed in the whereis program and that internationalization support was + added to some programs. These changes can be found by grep'ing for + "linux" in the source file, or by comparing the source file with the + original source. Other patches have been applied as they became + available. The best way to find out how the programs were patched is + to get the original source and do a diff. It is far too much overhead + for me to track these diffs individually. + + The getopt(3) from the NET-2 distribution is included, and is linked + with BSD NET-2 programs that use getopt(3). The BSD getopt behaves + differently from the standard GNU getopt. Please do *NOT* try to use + the GNU getopt for programs which require BSD getopt, since this may + change the program's behavior when a single '-' is given as an option. + The man page for getopt(3) is included for reference in the source + distribution, but is *NOT* installed in /usr/man/man3. + + Other changes that seemed significant: + + string.c needed a ':' after the 'n' in the getopt call. + +19) Several utilities are from the 4.4BSD-Lite distribution: + + banner (8.3 (Berkeley) 4/2/94) + column (8.3 (Berkeley) 4/2/94) + colcrt (8.1 (Berkeley) 6/6/93) + cal (8.4 (Berkeley) 4/2/94) [See README.cal for algorithm details] + logger (8.1 (Berkeley) 6/6/93) + look (8.1 (Berkeley) 6/14/93) + renice (8.1 (Berkeley) 6/9/93) + ul (8.1 (Berkeley) 6/6/93) + + To find the modifications, look for __linux__.

If you can live without the unmount-root + feature, then 0.99pl9 will work. * + +This is the first release of a set of utilities designed to automate +the management and checking of filesystems at boot time and shutdown. +It supports automatic and safe 'fsck' of all filesystems (including +root) at boot time by booting with root readonly; if the fsck succeeds +then root is remounted read-write and booting can continue. + +Why bother? + +Well, many people like to have a safe and reliable check of all their +filesystems during boot. This is especially true for ext2fs, because +all ext2fs filesystems have a special 'clean' flag which gets set when +the filesystem is cleaned (by e2fsck) or is unmounted cleanly, and +which gets unset when the filesystem is active. e2fsck can sense this +flag, and will skip over filesystems which are clean. + +This means that e2fsck won't bother you with a laborious filesystem +check at each startup, as long as you always shut down cleanly; but it +will check your filesystems automatically if you ever have a crash, +because afterwards the filesystem 'clean' flags will not be set. You +*can* still mount an unclean filesystem, but ext2fs will give you a +warning and will not mark it clean when it gets unmounted. + +One of the problems with automatic fsck'ing is that it is unsafe to +check mounted, active filesystems. The solution is to initially mount +only the root filesystem, and to mount it in readonly mode. In this +situation, fsck can run safely on all filesystems, without the danger +that the kernel might start conflicting with the repairs being done to +the filesystem. + +If any repairs were done, it is unsafe to proceed any further because +the kernel might have cached old information about the filesystems +which has been updated by fsck. However, if the fsck succeeded, then +we can remount the root filesystem in read-write mode and proceed to +mount all of the other filesystems. + +Finally, in order to ensure that filesystems are correctly tidied up +on shutdown, we need to unmount the root at shutdown. This is usually +done automatically; the standard Linux shutdown programs do a 'umount +- -a' command to unmount all mounted filesystems. You MUST have a +0.99pl10 or later kernel for this to work. Many versions of umount +explicitly do not try to unmount the root, since pre-99pl10 kernels +forbade this. The umount included here will unmount even the root +filesystem. (A special kernel trick in pl10 allows this to work by +keeping the filesystem alive in readonly mode after it has been tidied +up.) + +The bootup operation of this package is invoked by the /etc/rc shell +script, an example of which is in mount/etc/rc. It contains the +following important lines: + + # Check the integrity of all filesystems + /bin/fsck -A -a + # If there was a failure, drop into single-user mode. + if [ $? -gt 1 ] ; then + echo fsck failed. Please reboot. + sh + fi + + # Remount the root filesystem in read-write mode + /etc/mount -n -o remount /dev/hda3 / + + # remove /etc/mtab* so that mount will create it with a root entry + /bin/rm -f /etc/mtab* /etc/nologin /etc/utmp + + # mount file systems in fstab (and create an entry for /) + # but not NFS because TCP/IP is not yet configured + /etc/mount -avt nonfs + + +This is the first attempt at a complete package for automated clean +fsck support, so you may well find that you would like a slightly +different behaviour.

Use + rdev -R <kernel> 1 + to make the kernel mount in readonly mode. This can be overridden + by the use of the 'read-only' or 'read-write' keywords of the most + recent version of LILO. + +* Mount/umount package: This was recently posted to the net, and + implements the '-o remount' mount option which allows filesystems to + be remounted.

Devices called +"heads" move to specified places on the disk surface to read or write +information. There is usually one head on each side of every platter, +and all these heads are attached to a comb-like controller arm which +moves all of them at the same time, either closer to the centre of the +disk, or closer to the outer edge. + +Suppose the arm is in one position, putting an area of the disk +surface within reach of one or another of the heads. This total area, +everything that is accessible without moving the arm, is called a +"cylinder". (A cylinder is a barrel-shaped cross section of a disk, +consisting of a circular strip from each side of each platter.) The +part of a cylinder that one head can read or write without moving is +called a "track". + +Each track is divided into several pie-shaped slices called +"sectors", which are the smallest parts of the disk which can be read +or written at a time. The sectors on one disk are usually all the same +size. + +In fact, there are not always two heads to every platter, there are +some disks which do not have the same amount of data in every cylinder, +and there may be disks which do not have the same amount of data in +every sector. These features are usually hidden on PCs by the +controller card or the BIOS, which map the physical geometry of a disk +onto a logical geometry, which is what is actually used to access the +disk. + +The numbers which describe the "geometry" of a disk are + + 1. The number of cylinders it contains. + + 2. The number of tracks per cylinder, which is the number of heads. + + 3. The number of sectors per track. + + 4. The number of bytes per sector. + +These numbers vary from disk to disk, but a typical PC disk might +have about 1000 cylinders, half a dozen heads, and 15 or 20 sectors per +track, with each sector containing 512 bytes or characters; such a disk +contains 40 to 60 megabytes of data. A "double density" floppy disk +contains 40 cylinders, with 2 heads (2 tracks per cylinder), and with 9 +sectors per track; such a disk contains 360 kilobytes, or 360 * 1024 +characters. A "high density" 3.5 inch floppy contains 80 cylinders, +with 2 heads and 18 sectors per track, or 1.44 megabytes, or 1440 * +1024 characters. + +The exact size of a track or cylinder in bytes varies from one disk +to another. This `fdisk' for Linux deals mainly with cylinders, since +this is the best unit to use when allocating space for partitions. It +reports partition sizes in "blocks" of 1024 bytes, or 2 sectors, since +`mkswap' and the various `mkfs' programs require this number. A block +is the smallest amount of space which can be set aside for a file in +the current file systems. + +An operating system, such as Linux or DOS or OS/2, may use a disk in +any way that it wishes, but if two operating systems share the same +disk, they must agree on who owns what, or else one will interfere with +the other (that is, by damaging the other's files). A "partition" is a +section of a hard disk which is handled as a unit by all operating +systems which can access the disk. The standard way to define +partitions (for the moment) is the "partition table", a list of +information which is stored in parts of the disk that don't belong to +any of the systems using the disk. The beginning of the partition +table is stored in the disk's primary boot sector, and the rest is +stored in a chain of sectors scattered throughout the disk. + +The first sector on the disk is called the "primary boot block" or +"primary boot sector" because (1) it comes first, before other, similar +sectors; (2) it tells where the other, similar sectors are found, so +that it is logically `prior' to them; and (3) it usually contains code +which is executed when the system boots up. This sector contains a +table describing at most four partitions. These areas are called +"primary partitions". + +The partition table in the primary boot sector may also describe at +most one "extended partition". This is a large area of the disk, +usually containing all the space which is not in any primary partition. +Within this space we can set aside other areas which are called +"logical partitions", because they look almost exactly like primary +partitions. In fact, the main difference between them is that we can +boot from primary partitions, while we cannot boot from logical +partitions. This happens because the address of a primary partition is +in a fixed place, whereas the address of a secondary partition is not, +so we require a more complicated process to discover it, one which is +too difficult for most primary boot programs. + + +Dividing up your disk +--------------------- + +It is a good idea to plan ahead before you start creating partitions +on your disk. If you set aside a partition for some purpose, it is not +easy to change its size: you must all the data from the partition, +whether to floppies, to another partition, to another hard disk, or +somewhere else; then you must edit the table which describes this +partition, so changing its size; then you must reboot and initialise +the new partition, formatting it, for example, under DOS, or running +`mkfs' under Linux; finally you can copy all the data back. It is +possible, if you have several partitions, to copy data back and forth +between them while you change their sizes, but this is a bit risky and +time consuming. It is better to plan ahead what you will need, since +it is hard to change it afterwards. + +Many people with large disks and recent versions of DOS have their +entire file system on one large partition. They usually ask, `Isn't +there any way I can reformat my disk without copying everything off?' +There is no way to do it using standard DOS utilities, and there is no +truly safe way to do it using commercial software, because, if you make +a mistake, you will lose the entire contents of your disk. If you are +going to back up your disk anyway, you might as well copy the data back +safely. The Linux FAQ contains references to tools and procedures +which will allow you to do this, if you dare. + +DOS and Linux both allow you to access several partitions on a +single disk; on DOS these are treated as if they were separate disks or +drives, and under Linux they are treated as different "devices". + +You can have up to 64 partitions on a single IDE disk, or up to 16 +partitions on a single SCSI disk, at least as far as Linux is +concerned; in practice you will rarely want so many. The maximum size +of a Linux file system on a single partition depends on the type of +file system you use. Minix file systems are limited to 64 megabytes. +You may have all of your Linux files in a single partition, or you may +have two, three, or more Linux file systems. Similarly you may have +one or more DOS partitions. If you have several small partitions, you +run much less risk of losing all your files if your disk gets +corrupted. On the other hand, you may run out of space on a small +partition more easily. + +Under DOS, you must refer to each partition by a separate drive +letter, but all partitions are automatically accessible. Under Linux +only the root partition is automatically accessible, but once we mount +another partition, it is indistinguishable from the rest of the file +system. Disks are usually mounted by a command in one of the system +startup files, `/etc/rc', so you need not worry about having to do it +yourself whenever you boot the system. But even ordinary users may +be allowed to mount removable hard disks and floppy disks. + +Linux requires at least one partition, which is the `root' of the +file system. You may prefer to have a separate partition for `/usr', +which contains most of the executable files, or for `/home', which +contains most of your private files. You may also wish to set aside a +partition to use for swap space, depending on the amount of memory your +PC has. You will certainly need swap space if you have less than 4 Mb +of RAM and wish to compile anything substantial. You can reserve swap +space in a file, but you need a partition big enough to hold it, and +this will probably be less efficient than having a partition devoted to +swap. + +The disk space you need for Linux is discussed in README.prepare. + +Are you going to boot Linux from the hard disk, or will you boot +from a floppy? Some boot programs place severe restrictions on where +the boot partition can be. LILO is more relaxed about this, but does +require either the Master Boot Record on your first hard disk, or the +boot record on one of the first four partitions on your first hard disk. + +If you have an extended partition with logical partitions in it, you +can have only three primary partitions containing data. + + +The `fdisk' command +------------------- + +Every operating system, whether DOS, OS/2, or Linux, should provide +its own utility for editing hard disk partition tables. At least four +of these utilities have been called `fdisk', for `Fixed DISK setup +program', where `fixed' means `not removable'. I believe the first PC +program named `fdisk' came from Microsoft in about 1985; before that +time disks were too small to divide into separate sections. + +Every operating system has its own peculiarities. Normally you +should set up a partition for the use of one operating system by using +its own `fdisk' program. Do not use the Linux `fdisk' to create +partitions for DOS or for any system other than Linux; otherwise you +may have problems. + +An `fdisk' program performs two functions: it reports how the disk is +configured, and it changes that configuration by adding or deleting +partitions. Most `fdisk' programs can also change other information in +partition tables. + +This `fdisk' for Linux operates on one hard disk at a time. If you +give the command + + fdisk + +it reports on, and is able to change, `/dev/hda', the first hard +disk. (If you have no `/dev/hda', `fdisk' uses `/dev/sda' as the +default device.) To look at or change the second hard disk, `/dev/hdb', +give the command + + fdisk /dev/hdb + +To look at or change the first SCSI disk, give the command + + fdisk /dev/sda + +There are some special forms of the `fdisk' command. One of them, +suggested by Jim Winstead, simply lists all partitions on all available +disks: + + fdisk -l (where `l' is a letter, not the digit `1') + +The option `-v' is provided to list the current version of the +`fdisk' command. Finally, there is an option `-s' which is not really +intended for interactive use. It causes fdisk to print the size of a +partition in blocks of 1024 bytes as follows: + + fdisk -s /dev/hda7 + 39934 + +Because this is intended to be used by `mkfs' and `mkswap' programs, +it does not return the size of extended partitions or of partitions +whose system type code is less than 10 (hexadecimal a). If you start +`fdisk' without using one of these special options, it responds by +asking for a command: + + Command (m for help): _ + +Each `fdisk' command consists of a single letter, which must be +followed by <RETURN> before it is obeyed. Upper and lower case are not +distinguished. Anything you type after the first character is ignored. +Give the command `m', and you should see this menu: + Command action + a toggle a bootable flag + d delete a partition + l list known partition types + m print this menu + n add a new partition + p print the partition table + q quit without saving changes + t change a partition's system id + u change display/entry units + v verify the partition table + w write table to disk and exit + x extra functionality (experts only) + + Command (m for help): _ + +The simplest commands are Print, Verify, and Quit. On a small disk, the +Print command might produce a display like this one: + + Disk /dev/hda: 5 heads, 17 sectors, 977 cylinders + Units = cylinders of 85 * 512 bytes + + Device Boot Begin Start End Blocks Id System + /dev/hda1 * 1 1 236 10021+ 1 DOS 12-bit FAT + /dev/hda2 837 837 977 5992+ 5 Extended + /dev/hda3 * 237 237 836 25500 83 Linux native + /dev/hda5 837 837 936 4249+ 82 Linux swap + /dev/hda6 942 942 977 1522 1 DOS 12-bit FAT + +There are 5 partitions reported; `/dev/hda4' does not appear because +it is not allocated. Partitions 1 and 3 are flagged as bootable. The +size of each partition is reported in 1 kilobyte blocks; hence the +primary Linux partition, partition 3, is 25 1/2 megabytes in size. The +`+' after three of the sizes warns that these partitions contain an odd +number of sectors: Linux normally allocates filespace in 1 kilobyte +blocks, so the extra sector in partition 5 is wasted. Id numbers are +reported in hexadecimal and explained in English. + +The display/entry units may be either cylinders or sectors. The +default is cylinders, but changing the units makes the print command +display the following table for the system reported above: + + Disk /dev/hda: 5 heads, 17 sectors, 977 cylinders + Units = sectors of 1 * 512 bytes + + Device Boot Begin Start End Blocks Id System + /dev/hda1 * 1 17 20059 10021+ 1 DOS 12-bit FAT + /dev/hda2 71060 71060 83044 5992+ 5 Extended + /dev/hda3 * 20060 20060 71059 25500 83 Linux native + /dev/hda5 71061 71061 79559 4249+ 82 Linux swap + /dev/hda6 79985 80001 83044 1522 1 DOS 12-bit FAT + +The start of data in both DOS partitions is 16 sectors after the +beginning of the partition: this is one reason why you should use DOS's +own `FDISK' to create DOS partitions. Changing the units to sectors +also affects the way in which the new partition command asks for the +beginning and end of a new partition. + +*Warning*: it is dangerous to create a new partition when the +display/entry units are sectors. + +The Verify command is useful because + + 1. It warns you if anything is wrong. *Always* give a Verify command + before writing any changes to disk. + + 2. It reports how many unallocated sectors there are on the disk. + +The Quit command is also useful. `fdisk' does not actually change +any data on your disk unless you give a Write command. If you are +unhappy about any changes you may have made, give the Quit command, and +your disk will remain as it was before you ran `fdisk'. You can also +interrupt `fdisk' with `CTRL-C'. + + +Deleting and adding partitions +------------------------------ + +Deleting a partition is simple. Give the Delete command by typing +`d'. `fdisk' asks: + + Partition number (1-6): _ + +Once you get this far, you must either delete a partition or +interrupt the program with `CTRL-C' (or whatever your current interrupt +character is). Note: + + 1. You may delete a nonexistent partition. You will get a warning + message. + + 2. You may delete an extended partition. This has the side effect of + deleting all partitions greater than or equal to 5. + + 3. You may delete a logical partition. In that case, all partitions + above it are renumbered at once. For example, if you delete + partition 5, then partition 6 becomes known as partition 5, and + partition 7 as partition 6. + +Adding a partition is just a bit more complicated. Give the New +command by typing `n'. `fdisk' allows you to + + 1. Create a primary partition, if there is a free slot in the primary + partition table. + + 2. Create an extended partition if there is a free slot in the + primary partition table, and if there is no extended partition. + + 3. Create a logical partition if an extended partition exists. + +If more than one of these actions is possible, you will be asked to +select Primary, Extended, or Logical, depending on what is currently +permissible. Before you create a primary or an extended partition, you +are asked what slot it is to have in the table (1-4). + +You may not add a primary or an extended partition if the selected +slot in the primary partition table is already occupied: in that case +you simply return to the main menu. You are not allowed to add a new +primary partition unless there are sectors available outside the +extended partition. You are not allowed to add a new logical partition +unless there are sectors available inside the extended partition. + +If space is available, you are prompted for the first cylinder: + + First sector (237-977): _ + +The limits are the lowest and the highest cylinders in which sectors +are available in the appropriate part of the disk. Not all numbers in +this range are necessarily available: they may fall inside an existing +partition. If you select a cylinder which is already in use, you are +told off and prompted again for the first cylinder. After selecting the +first cylinder, you are prompted again: + + Last cylinder or +size or +sizeM or +sizeK (237-836): _ + +The limits are the cylinder you have chosen as the first cylinder, +and the highest cylinder which contains a legitimate upper boundary for +the new partition. In other words, all numbers in the given range are +legitimate, unlike those in the first range of cylinders. You may also +specify the size of a partition in megabytes, kilobytes, or in the +current units (cylinders or sectors). A plus sign `+' indicates that +your answer is a size rather than a boundary, and the suffix `m' or `k' +(upper or lower case) indicates that the size is not given in units of +sectors or cyliners, but in megabytes or kilobytes respectively. Thus +possible answers to the last cylinder request above are + +700 + Make cylinder 700 the last cylinder in the partition. + ++300 + Make cylinder 537 the last cylinder in the partition. + ++15m + Make the partition at least 15 megabytes in size. + ++12500k + Make the partition at least 12,500 kilobytes in size. + +If you specify a size which is too large or an end which is out of +range, the prompt is simply repeated. + +Adding or deleting partitions has no effect unless you subsequently +give the Write command. Please remember to give the Verify command +first, just before giving the Write command: this is a safety +precaution. After giving the Write command, you will see this message: + + The partition table has been altered! + Calling ioctl() to re-read partition table. + Syncing disks. + +If there are no further messages, the kernel has successfully copied +the information from the partition table into its own internal table. +But sometimes you will see a message like this one: + + Re-read table failed with error 16: Device or resource busy. + Reboot your system to ensure the partition table is updated. + +In this case, depending on what you have changed in the partition +table, it may be dangerous to continue working without rebooting, +since you may lose or corrupt your data. + + +Here are some important things to note: + + 1. Before you reboot, you *may* run `fdisk' again, either to manage + another disk, or to make additional changes to the same disk, or + just to check that the changes have been made as you expected. + This is true even after you receive the message warning you to + reboot. + + 2. It is not a good idea to run any of the programs `mkfs', `mkswap', + `mount', or `swapon' if you have received the warning message but + have not rebooted. In this case it is dangerous to run any program, + but these in particular may cause serious damage to the data on your + disk, including the partition tables themselves. + + +Active flags and system types +----------------------------- + +The active flag is a bit in the partition table entry which marks a +partition as bootable. This is important to some primary boot sector +programs, which will not boot from an unflagged partition. Other such +programs do not allow more than one partition to be flagged. Some, +like LILO, ignore the flags completely. I prefer to flag all bootable +partitions as active so that they stand out on the menu which `fdisk' +lists. Fdisk prints a star after the name of a partition's device file +if its active flag is set. + +The Active command changes, or toggles, a partition's active flag. +Give the Active command, and select a partition by number. If it was +marked inactive, it will be flagged as active; if it was flagged as +active, it will be marked inactive. You may set the active flag on an +extended or logical partition, though the meaning of such a flag is by +no means clear. This can be used to install LILO as a secondary boot +loader to boot a Linux which lives on a second hard disk. + +The Type command changes the ID number which describes what type a +partition is. `fdisk' currently recognises 30 system IDs, in the sense +that it prints a string for each of them, but it allows you to change +any system ID to any other, with the following exceptions: you may not +change any partition to or from the type Extended, and you may not +change a partition whose type is Empty (0) to any other type. You may, +however, change the type of any data partition to 0, which is +equivalent to deleting it. + +The new system ID or type code is a hexadecimal number. There are +two ways of listing the numbers which `fdisk' recognises: use the List +command, which prints the list, or use the Type command, which, when it +prompts you for the code, says + + Hex code (type L to list codes): _ + +where the upper case `L' is used for clarity. The codes printed are: +Some of these numbers are a trifle uncertain. By default `fdisk' uses +a type of 83. It used to use 81, the type code used by the MINIX +`fdisk'. It seemed prudent to change the default since (a) many Linux +`minix' file systems are no longer compatible with MINIX, (b) the ext2 +file system, a native Linux file system, is fairly stable, as is the +Xia file system, and (c) the number 81 causes problems with DR-DOS. +Linux does not usually care what values you use for type codes, but +other systems, in particular DOS, OS/2, and DR-DOS, may. + +The value of 82 for Linux swap partitions is my own invention, and +is intended to give some recognisable distinction to the partitions +when the values are displayed in hexadecimal. + +New active flags and new system type codes are not written to the +disk until you exit from `fdisk' with the Write command, as described +above, in the section on deleting and adding partitions. + + +Extra commands for experts +-------------------------- + +The eXtra command `x' puts `fdisk' into `expert' mode, in which a +slightly different set of commands is available. The Active, Delete, +List, New, Type, Verify, and `eXpert' commands are not available in +expert mode. The commands Write and Quit are available as in ordinary +mode, the Print command is available, but produces output in a slightly +different format, and of course the Menu command prints the expert +menu. There are several new commands. + + 1. The Return command brings you back to the main menu. + + 2. The Extended command prints the list of table entries which point + to other tables. Ordinary users do not need this information. + The data is shown as it is stored. The same format is used for + the expert Print command. + + 3. The dangerous Begin command allows you to move the start of data + in a partition away from its beginning. Other systems create + partitions with this format, and it is sometimes useful to be able + to reproduce it. + + 4. The slightly dangerous Cylinders command allows you to change the + available number of cylinders. For SCSI disk owners, note that we + require not the actual number of physical cylinders, but the + number of logical cylinders used by DOS and other operating + systems. + + 5. The extremely dangerous Heads and Sectors commands allow you to + change the number of heads and sectors. It should not be + necessary to use these commands unless you have a SCSI disk, whose + geometry Linux is not always able to determine. SCSI disk owners + note that we need not the actual number of heads or of sectors per + track, but the number believed to exist by DOS and other operating + systems. *Warning*: If you set either of these numbers to a bad + value, you may lose all data on your disk. + +Always, after giving any of the commands Begin, Cylinder, Heads, or +Sectors, you should Return to the main menu and give the Verify command. + + +Warnings for `fdisk' users +-------------------------- + +In general, you should not use this `fdisk' program to create +partitions for other operating systems, only for Linux. Nor should you +use `fdisk' commands from other operating systems do create partitions +for Linux. + +DR-DOS 5.0 and 6.0 are reported to have difficulties with partition +ID codes of 80 or more. The Linux `fdisk' used to set the system type +of new partitions to hexadecimal 81. DR-DOS seems to confuse this with +hexadecimal 1, a DOS code. The values 82 for swap and 83 for file +systems should not cause problems with DR-DOS. If they do, you may use +the `fdisk' command `t' to change the system code of any Linux +partitions to some number less than hexadecimal 80; I suggest 42 and 43 +for the moment. + +Partitioning a hard disk may destroy data which is on that disk if you +are not careful. Go slowly, write down a description of the partition +tables before you changed them, and always verify before you write. + +Most operating systems and utilities expect that all partitions begin and +end at cylinder boundaries. This version of `fdisk' does so by default, +but you can use it to create partitions which begin or end anywhere. +This does not normally affect Linux, but it is very dangerous, as other +operating systems (including DOS) may try to `correct' the partition +boundaries. + +It is dangerous to create a new partition when the display/entry +units are sectors. + +The Verify command warns you if anything is wrong. *Always* give a +Verify command before writing any changes to disk. + +If you set the disk geometry (tracks per cylinder, or sectors per +track) to an incorrect value, you may lose all data on your disk. diff --git a/disk-utils/cfdisk.8 b/disk-utils/cfdisk.8 new file mode 100644 index 00000000..cb23149f --- /dev/null +++ b/disk-utils/cfdisk.8 @@ -0,0 +1,407 @@ +.\" cfdisk.8 -- man page for cfdisk +.\" Copyright 1994 Kevin E.

The +.I device +can be any one of the following: +.sp +.nf +.RS +/dev/hda [default] +/dev/hdb +/dev/sda +/dev/sdb +/dev/sdc +/dev/sdd +.RE +.fi + +.B cfdisk +first tries to read the geometry of the hard disk. If it fails, an +error message is displayed and +.B cfdisk +exits. This should only happen when partitioning a SCSI drive on an +adapter without a BIOS. To correct this problem, you can set the +.IR cylinders ", " heads " and " sectors-per-track +on the command line. Next, +.B cfdisk +tries to read the current partition table from the disk drive. If it +is unable to figure out the partition table, an error is displayed and +the program will exit. This might also be caused by incorrect +geometry information, and can be overridden on the command line. +Another way around this problem is with the +.B \-z +option. This will ignore the partition table on the disk. + +The main display is composed of four sections, from top to bottom: the +header, the partitions, the command line and a warning line. The +header contains the program name and version number followed by the +disk drive and its geometry. The partitions section always displays +the current partition table. The command line is the place where +commands and text are entered. The available commands are usually +displayed in brackets. The warning line is usually empty except when +there is important information to be displayed. The current partition +is highlighted with reverse video (or an arrow if the +.B \-a +option is given). All partition specific commands apply to the +current partition. + +The format of the partition table in the partitions section is, from +left to right: Name, Flags, Partition Type, Filesystem Type and Size. +The name is the partition device name. The flags can be +.IR Boot , +which designates a bootable partition or +.IR NC , +which stands for "Not Compatible with DOS or OS/2". DOS, OS/2 and +possibly other operating systems require the first sector of the first +partition on the disk and all logical partitions to begin on the +second head. This wastes the second through the last sector of the +first track of the first head (the first sector is taken by the +partition table itself). +.B cfdisk +allows you to recover these "lost" sectors with the maximize command +.RB ( m ). +.I Note: +.BR fdisk (8) +and some early versions of DOS create all partitions with the number +of sectors already maximized. For more information, see the maximize +command below. The partition type can be one of +.IR Primary " or " Logical . +For unallocated space on the drive, the partition type can also be +.IR Pri/Log , +or empty (if the space is unusable). The filesystem type section +displays the name of the filesystem used on the partition, if known. +If it is unknown, then +.I Unknown +and the hex value of the filesystem type are displayed. A special +case occurs when there are sections of the disk drive that cannot be +used (because all of the primary partitions are used). When this is +detected, the filesystem type is displayed as +.IR Unusable . +The size field displays the size of the partition in megabytes (by +default). It can also display the size in sectors and cylinders (see +the change units command below). If an asterisks +.RB ( * ) +appears after the size, this means that the partition is not aligned +on cylinder boundaries. +.SH "DOS 6.x WARNING" + +The DOS 6.x FORMAT command looks for some information in the first +sector of the data area of the partition, and treats this information +as more reliable than the information in the partition table. DOS +FORMAT expects DOS FDISK to clear the first 512 bytes of the data area +of a partition whenever a size change occurs. DOS FORMAT will look at +this extra information even if the /U flag is given -- we consider +this a bug in DOS FORMAT and DOS FDISK. + +The bottom line is that if you use cfdisk or fdisk to change the size of a +DOS partition table entry, then you must also use +.B dd +to zero the first 512 bytes of that partition before using DOS FORMAT to +format the partition. For example, if you were using cfdisk to make a DOS +partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk +and rebooting Linux so that the partition table information is valid) you +would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero +the first 512 bytes of the partition. +.B BE EXTREMELY CAREFUL +if you use the +.B dd +command, since a small typo can make all of the data on your disk useless. + +.B BE EXTREMELY CAREFUL +if you use the +.B dd +command, since a small typo can make all of the data on your disk useless. + +For best resutls, you should always use an OS-specific partition table +program. For example, you should make DOS partitions with the DOS FDISK +program and Linux partitions with the Linux fdisk or Linux cfdisk program. + +.SH COMMANDS +.B cfdisk +commands can be entered by pressing the desired key (pressing +.I Enter +after the command is not necessary). Here is a list of the available +commands: +.TP +.B b +Toggle bootable flag of the current partition. This allows you to +select which primary partition is bootable on the drive. +.TP +.B d +Delete the current partition. This will convert the current partition +into free space and merge it with any free space immediately +surrounding the current partition. A partition already marked as free +space or marked as unusable cannot be deleted. +.TP +.B g +Change the disk geometry (cylinders, heads, or sectors-per-track). +.B WARNING: +This option should only be used by people who know what they are +doing. A command line option is also available to change the disk +geometry. While at the change disk geometry command line, you can +choose to change cylinders +.RB ( c ), +heads +.RB ( h ), +and sectors per track +.RB ( s ). +The default value will be printed at the prompt which you can accept +by simply pressing the +.I Enter +key, or you can exit without changes by pressing the +.I ESC +key. If you want to change the default value, simply enter the +desired value and press +.IR Enter . +The altered disk parameter values do not take effect until you return +the main menu (by pressing +.IR Enter " or " ESC +at the change disk geometry command line. If you change the geometry +such that the disk appears larger, the extra sectors are added at the +end of the disk as free space. If the disk appears smaller, the +partitions that are beyond the new last sector are deleted and the +last partition on the drive (or the free space at the end of the +drive) is made to end at the new last sector. +.TP +.B h +Print the help screen. +.TP +.B m +Maximize disk usage of the current partition. This command will +recover the the unused space between the partition table and the +beginning of the partition, but at the cost of making the partition +incompatible with DOS, OS/2 and possibly other operating systems. +This option will toggle between maximal disk usage and DOS, OS/2, +etc. compatible disk usage. The default when creating a partition is +to create DOS, OS/2, etc. compatible partitions. +.TP +.B n +Create new partition from free space. If the partition type is +.IR Primary " or " Logical , +a partition of that type will be created, but if the partition type is +.IR Pri/Log , +you will be prompted for the type you want to create. Be aware that +(1) there are only four slots available for primary partitions and (2) +since there can be only one extended partition, which contains all of +the logical drives, all of the logical drives must be contiguous (with +no intervening primary partition). +.B cfdisk +next prompts you for the size of the partition you want to create. +The default size, equal to the entire free space of the current +partition, is display in megabytes. You can either press the +.I Enter +key to accept the default size or enter a different size at the +prompt. +.B cfdisk +accepts size entries in megabytes +.RB ( M ) +[default], kilobytes +.RB ( K ), +cylinders +.RB ( C ) +and sectors +.RB ( S ) +by entering the number immediately followed by one of +.RB ( M ", " K ", " C " or " S ). +If the partition fills the free space available, the partition is +created and you are returned to the main command line. Otherwise, the +partition can be created at the beginning or the end of the free +space, and +.B cfdisk +will ask you to choose where to place the partition. After the +partition is created, +.B cfdisk +automatically adjusts the other partition's partition types if all of +the primary partitions are used. +.TP +.B p +Print the partition table to the screen or to a file. There are +several different formats for the partition that you can choose from: +.sp +.RS +.TP +.B r +Raw data format (exactly what would be written to disk) +.TP +.B s +Partition table in sector order format +.TP +.B t +Partition table in raw format +.RE + +.RS +The +.I raw data format +will print the sectors that would be written to disk if a +.BR w rite +command is selected. First, the primary partition table is printed, +followed by the partition tables associated with each logical +partition. The data is printed in hex byte by byte with 16 bytes per +line. + +The +.I partition table in sector order format +will print the partition table ordered by sector number. The fields, +from left to right, are the number of the partition, the partition +type, the first sector, the last sector, the offset from the first +sector of the partition to the start of the data, the length of the +partition, the filesystem type (with the hex value in parenthesis), +and the flags (with the hex value in parenthesis). In addition to the +primary and logical partitions, free and unusable space is printed and +the extended partition is printed before the first logical partition. + +If a partition does not start or end on a cylinder boundary or if the +partition length is not divisible by the cylinder size, an asterisks +.RB ( * ) +is printed after the non-aligned sector number/count. This usually +indicates that a partition was created by an operating system that +either does not align partitions to cylinder boundaries or that used +different disk geometry information. If you know the disk geometry of +the other operating system, you could enter the geometry information +with the change geometry command +.RB ( g ). + +For the first partition on the disk and for all logical partitions, if +the offset from the beginning of the partition is not equal to the +number of sectors per track (i.e., the data does not start on the +first head), a number sign +.RB ( # ) +is printed after the offset. For the remaining partitions, if the +offset is not zero, a number sign will be printed after the offset. +This corresponds to the +.I NC +flag in the partitions section of the main display. + +The +.I partition table in raw format +will print the partition table ordered by partition number. It will +leave out all free and unusable space. The fields, from left to +right, are the number of the partition, the flags (in hex), the +starting head, sector and cylinder, the filesystem ID (in hex), the +ending head, sector and cylinder, the starting sector in the partition +and the number of sectors in the partition. The information in this +table can be directly translated to the +.IR "raw data format" . + +The partition table entries only have 10 bits available to represent +the starting and ending cylinders. Thus, when the absolute starting +(ending) sector number is on a cylinder greater than 1023, the maximal +values for starting (ending) head, sector and cylinder are printed. +This is the method used by OS/2, and thus fixes the problems +associated with OS/2's fdisk rewriting the partition table when it is +not in this format. Since Linux and OS/2 use absolute sector counts, +the values in the starting and ending head, sector and cylinder are +not used. +.RE +.TP +.B q +Quit program. This will exit the program without writing any data to +disk. +.TP +.B t +Change the filesystem type. By default, new partitions are created as +.I Linux +partitions, but since +.B cfdisk +can create partitions for other operating systems, change partition +type allows you to enter the hex value of the filesystem you desire. +A list of the know filesystem types is displayed. You can type in the +filesystem type at the prompt or accept the default filesystem type +.RI [ Linux ]. +.TP +.B u +Change units of the partition size display. It will rotate through +megabytes, sectors and cylinders. +.TP +.B W +Write partition table to disk (must enter an upper case W). Since +this might destroy data on the disk, you must either confirm or deny +the write by entering `yes' or `no'. If you enter `yes', +.B cfdisk +will write the partition table to disk and the tell the kernel to +re-read the partition table from the disk. The re-reading of the +partition table works is most cases, but I have seen it fail. Don't +panic. It will be correct after you reboot the system. In all cases, +I still recommend rebooting the system--just to be safe. +.TP +.I Up Arrow +.TP +.I Down Arrow +Move cursor to the previous or next partition. If there are more +partitions than can be displayed on a screen, you can display the next +(previous) set of partitions by moving down (up) at the last (first) +partition displayed on the screen. +.TP +.I CTRL-L +Redraws the screen.

For example, +.B /dev/hda1 +is the first partition on the first hard disk in the system. + +If possible, +.B fdisk +will obtain the disk geometry automatically. This is +.I not +necessarily the +.I physical +disk geometry, but is the disk geometry that MS-DOS uses for the partition +table. If +.B fdisk +warns you that you need to set the disk geometry, please believe this +statement, and set the geometry. This should only be necessary with +certain SCSI host adapters (the drivers for which are rapidly being +modified to provide geometry information automatically). + +Whenever a partition table is printed out, a consistency check is performed +on the partition table entries. This check verifies that the physical and +logical start and end points are identical, and that the partition starts +and ends on a cylinder boundary (except for the first partition). + +Old versions of fdisk (all versions prior to 1.1r [including 0.93]) +incorrectly mapped the cylinder/head/sector specification onto absolute +sectors. This may result in the first partition on a drive failing the +consistency check. If you use LILO to boot, this situation can be ignored. +However, there are reports that the OS/2 boot manager will not boot a +partition with inconsistent data. + +Some versions of MS-DOS create a first partition which does not begin +on a cylinder boundary, but on sector 2 of the first cylinder. +Partitions beginning in cylinder 1 cannot begin on a cylinder boundary, but +this is unlikely to cause difficulty unless you have OS/2 on your machine. + +In version 1.1r, a BLKRRPART ioctl() is performed before exiting when the +partition table is updated. This is primarily to ensure that removable +SCSI disks have their partition table information updated. If the kernel +does not update its partition table information, fdisk warns you to +reboot. If you do not reboot your system after receiving such a warning, +you may lose or corrupt the data on the disk. Sometimes BLKRRPART fails +silently, when installing Linux, you should +.I always +reboot after editing the partition table. + +.SH "DOS 6.x WARNING" + +The DOS 6.x FORMAT command looks for some information in the first +sector of the data area of the partition, and treats this information +as more reliable than the information in the partition table. DOS +FORMAT expects DOS FDISK to clear the first 512 bytes of the data area +of a partition whenever a size change occurs. DOS FORMAT will look at +this extra information even if the /U flag is given -- we consider +this a bug in DOS FORMAT and DOS FDISK. + +The bottom line is that if you use cfdisk or fdisk to change the size of a +DOS partition table entry, then you must also use +.B dd +to zero the first 512 bytes of that partition before using DOS FORMAT to +format the partition. For example, if you were using cfdisk to make a DOS +partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk +and rebooting Linux so that the partition table information is valid) you +would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero +the first 512 bytes of the partition. +.B BE EXTREMELY CAREFUL +if you use the +.B dd +command, since a small typo can make all of the data on your disk useless. + +.B BE EXTREMELY CAREFUL +if you use the +.B dd +command, since a small typo can make all of the data on your disk useless. + +For best resutls, you should always use an OS-specific partition table +program. For example, you should make DOS partitions with the DOS FDISK +program and Linux partitions with the Linux fdisk or Linux cfdisk program. + +.SH OPTIONS +.TP +.B \-v +Prints version number of +.B fdisk +program. +.TP +.B \-l +Lists the partition tables for +.BR /dev/hda , +.BR /dev/hdb , +.BR /dev/sda , +.BR /dev/sdb , +.BR /dev/sdc , +.BR /dev/sdd , +.BR /dev/sde , +.BR /dev/sdf , +.BR /dev/sdg , +.BR /dev/sdh , +and then exits. +.TP +.BI \-s partition +If the +.I partition +is not a DOS partition (i.e., the partition id is greater than 10), then +the +.I size +of that partition is printed on the standard output. This value is +normally used as an argument to the +.BR mkfs (8) +program to specify the size of the partition which will be formatted. +.SH BUGS +Although this man page (written by faith@cs.unc.edu) is poor, there is +.I excellent +documentation in the README.fdisk file (written by LeBlanc@mcc.ac.uk) that +should always be with the fdisk distribution. If you cannot find this file +in the +.I util-linux-* +directory or with the +.I fdisk.c +source file, then you should write to the distributor of your version of +.B fdisk +and complain that you do not have all of the available documentation. +.SH AUTHOR +A.

If +.B \-w +is given, the output is scrunched down from a width of 132 to +.I n , +suitable for a narrow terminal. If +.I n +is omitted, it defaults to 80. +.PP +The output should be printed on a hard-copy device, up to 132 columns wide, +with no breaks between the pages. The volume is great enough that you +may want +a printer or a fast hardcopy terminal, but if you are patient, a +decwriter or other 300 baud terminal will do. +.SH BUGS +Several ASCII characters are not defined, notably <, >, [, ], \\, +^, _, {, }, |, and ~. Also, the characters ", ', and & are funny +looking (but in a useful way.) +.PP +The +.B \-w +option is implemented by skipping some rows and columns. +The smaller it gets, the grainier the output. +Sometimes it runs letters together. +.SH AUTHOR +Mark Horton diff --git a/games/banner.c b/games/banner.c new file mode 100644 index 00000000..65d04e5d --- /dev/null +++ b/games/banner.c @@ -0,0 +1,1165 @@ +/* + * Copyright (c) 1980, 1993, 1994 + * The Regents of the University of California.

If not, make it using + + mknod /dev/tty0 c 4 0 + +3. Build the program +-------------------- + + - Type `make' in the directory in which you unpacked the selection code; + this will build the `selection' executable. It has been tested with + gcc 2.3.3 and libc.so.4.3.3. + + - Run `selection &' to test it out. Use `selection -?' to see what + options are supported. Then type `make install', which installs the + executable in /etc and the manual page in /usr/man, and start it up + from /etc/rc.local. Consult the manual page for usage. It should + work with text screens of various sizes, e.g. 80x28, 80x50, etc. + +The default size of the paste buffer is 2048 bytes.

A highlighted +block will start moving around the screen, correlated with the movement of the +mouse. +.PP +Move the block to the first character of the selection, then press and hold +down the copy button. +.PP +Drag out the selection; the selected text will be highlighted. Then release +the copy button. You can take the end of the selection to before the start of +the selection if necessary. +.PP +Double-clicking the copy button while the highlighted block is on the +screen selects text by word boundaries; treble-clicking selects by entire +lines. If the button is held down after double- or treble-clicking, multiple +words or lines may be selected. A word consists of a set of alphanumeric +characters and underscores. +.PP +If a trailing space after the contents of a line is highlighted, and if there +is no other text on the remainder of the line, the rest of the line will be +selected automatically. If a number of lines are selected, highlighted +trailing spaces on each line will be removed from the selection buffer. +.PP +Pressing the paste button in any virtual console pastes the +selected text into the read queue of the associated tty. +.PP +Any output on the virtual console holding the selection will clear the +highlighted selection from the screen, to maintain integrity of the display, +although the contents of the paste buffer will be unaffected. +.PP +The selection mechanism is disabled if the controlling virtual console is +placed in graphics mode, for example when running X11, and is re-enabled when +text mode is resumed. (But see BUGS section below.) +.SH FILES +/dev/mouse - default mouse device +.br +/dev/console - current VC device +.SH DIAGNOSTICS +\fBselection\fR complains if any of the devices it requires cannot be located. +.SH BUGS +The size of the paste buffer is set at 2048 bytes by default. This may be +changed at compile time; consult the installation notes. +.PP +The selection mechanism doesn't work very well with graphics characters, or +indeed with any characters where a mapping between the typed character and +the displayed character is performed by the console driver. The selection +mechanism pastes into the input buffer the character codes as they are +displayed on the screen, not those originally typed in by the user. +.PP +Because of the way that the kernel bus mouse drivers work, allowing only one +process to have the mouse device open at once, \fBselection\fR cannot +co-exist with X11 using ATI XL, Logitech and Microsoft bus mice or with a +PS/2 mouse. The X server will not start while \fBselection\fR is running. +This problem is not present with serial mice. +.SH AUTHOR +.nf +Andrew Haylett <ajh@gec-mrc.co.uk> +.SH ACKNOWLEDGEMENTS +.nf +Lefty patches originally suggested by: +.ti +4 +Sotiris C.

To gain the full benefit of this, get the newest + last from the admutils-1.4.tar.Z package or later. + +Version 1.6 (29-Aug-92): changes since 1.5: + This is for Linux 0.97P1+ or later. + + Login now uses the newly implemented vhangup() sys-call, to prevent + snooping on the tty. + An alternative getpass() function is now provided with login, because + I was told that the old one in libc didn't work with telnet and + or rlogin. I don't have a network or a kernel with TCP/IP so I haven't + tested the new one with telnet, but it is derived from BSD sources + that are supposed to work with networking. + +Version 1.5 (12-Aug-92): changes since 1.4 + This is for Linux 0.97 or later, and has been built with gcc2.2.2 + + This release just puts in a few bugfixes in login.c and simpleinit.c + +Version 1.4 (4-Jul-92): changes since 1.3: + This is for Linux 0.96b, and has been built and tested with gcc 2.2.2. + + Init now handles the SIGINT signal.

This + makes sense because after Linux 0.96B-PL1 the key-combination + Ctrl-Alt-Del may send a SIGINT to init instead of booting the + machine the hard way without syncing or anything. + + You may want to get the admutils-1.1 package which includes a program + that will instruct the kernel to use the "gentle-reboot" procedure. + +Version 1.3 (14-Jun-92): changes since 1.2: + This is for Linux 0.96A. + + The ioctl(TIOCSWINSZ) has been removed from login.c because it now + works :-). + + login.c now supports a lastlog database. + + Several programs and pieces of source that were included in the 1.2 + package has been *removed* as they are incorporated into the new + libc. Other omitted parts such as last(1) has been replaced by + better versions, and can be found in the admutils package. + + Agetty is now called getty and will be placed in /etc. + + A few changes has been made to make it possible to compile the + stuff with GCC 2.x. + +Version 1.2 (28-Feb-92): changes since 1.1: + This is for Linux 0.12. + + A couple of problems with simpleinit.c has been solved, thanks to + Humberto Zuazaga. So now init groks comments in /etc/inittab, and + handles the HUP and TSTP signals properly. + + I added two small scripts to the distribution: users and mesg. + + TERM is now carried through from /etc/inittab all the way to the + shell. Console tty's are special-cased, so the termcap entry in + /etc/inittab is overridden by the setting given at boot-time. + This requires a different patch to the kernel than that distributed + with version 1.1 + + Login no more sends superfluous chars from a password to the + shell. It also properly prints a NL after the password. + + Agetty didn't set the erase character properly, it does now. + + A few extra defines has been added to utmp.h + + Several netters helped discover the bugs in 1.1. Thanks to them + all. + +Version 1.1 (released 19-Feb-92): Changes since 1.0: + A bug in simpleinit.c has been fixed, thanks to Pietro Castelli. + The definition of the ut_line field has been changed to track the + USG standard more closely, we now strip "/dev/" off the front. + Thanks to: Douglas E. Quale and Stephen Gallimore. + + I have added a getlogin.c library routine, and a write(1) command. + I removed the qpl-init stuff. If people want to use it, they should + get it from the source. I don't want to hack on it anymore. + + A couple of people reported problems with getty having problems + with serial terminals. That was correct. I borrowed a null-modem + from Tommy Thorn, and now the problems should be fixed. It seems + that there is kept a lot of garbage in the serial buffers, flush + them and it works like a charm. Getty does an ioctl(0, TCFLSH, 2) + for this. + + The write.c code now doubles as code for a wall(1) program. + +Description of the various files: + +login.c The login program. This is a portation of BSD login, first + to HP-UX 8.0 by Michael Glad (glad@daimi.aau.dk), and + to Linux (initially to 0.12) by me. + +who.c A simple who(1) util. to list utmp.

LILO. If /etc/securesingle exists it will ask for the + root password before starting single user. + +write.c A write(1) command, used to pass messages between users + at different terminals.

The following special +characters are recognized: @ and Control-U (kill); #, DEL and +back space (erase); carriage return and line feed (end of line). +.IP o +Optionally deduces the baud rate from the CONNECT messages produced by +Hayes(tm)-compatible modems. +.IP o +Optionally does not hang up when it is given an already opened line +(useful for call-back applications). +.IP o +Optionally does not display the contents of the \fI/etc/issue\fP file +(System V only). +.IP o +Optionally invokes a non-standard login program instead of +\fI/bin/login\fP. +.IP o +Optionally turns on hard-ware flow control +.IP o +Optionally forces the line to be local with no need for carrier detect. +.PP +This program does not use the \fI/etc/gettydefs\fP (System V) or +\fI/etc/gettytab\fP (SunOS 4) files. +.SH ARGUMENTS +.na +.nf +.fi +.ad +.TP +port +A path name relative to the \fI/dev\fP directory.

Each time +\fIagetty\fP receives a BREAK character it advances through +the list, which is treated as if it were circular. +.sp +Baud rates should be specified in descending order, so that the +null character (Ctrl-@) can also be used for baud rate switching. +.TP +term +The value to be used for the TERM environment variable.

It is left up to the +application to disable software (XON/XOFF) flow protocol where +appropriate. +.TP +-i +Do not display the contents of \fI/etc/issue\fP before writing the +login prompt. Terminals or communications hardware may become confused +when receiving lots of text at the wrong baud rate; dial-up scripts +may fail if the login prompt is preceded by too much text. +.TP +-l login_program +Invoke the specified \fIlogin_program\fP instead of /bin/login. +This allows the use of a non-standard login program (for example, +one that asks for a dial-up password or that uses a different +password file). +.TP +-m +Try to extract the baud rate the \fIconnect\fP status message +produced by some Hayes(tm)-compatible modems. These status +messages are of the form: "<junk><speed><junk>". +\fIagetty\fP assumes that the modem emits its status message at +the same speed as specified with (the first) \fIbaud_rate\fP value +on the command line. +.sp +Since the \fI-m\fP feature may fail on heavily-loaded systems, +you still should enable BREAK processing by enumerating all +expected baud rates on the command line. +.TP +-t timeout +Terminate if no user name could be read within \fItimeout\fP +seconds. This option should probably not be used with hard-wired +lines. +.TP +-L +Force the line to be local line with no need for carrier detect.

It can also be used to switch from one +user to another at any time (most modern shells have support for this +feature built into them, however). + +If an argument is not given, +.B login +prompts for the username. + +If the user is +.I not +root, and if +.I /etc/nologin +exists, the contents of of this file are printed to the screen, and the +login is terminated. This is typically used to prevent logins when the +system is being taken down. + +If the user is root, then the login must be occuring on a tty listed in +.IR /etc/securetty . +Failures will be logged with the +.B syslog +facility. + +After these conditions are checked, the password will be requested and +checks (if a password is required for this username). Ten attempts are +allowed before +.B login +dies, but after the first three, the response starts to get very slow. +Login failures are reported via the +.B syslog +facility. This facility is also used to report any successful root logins. + +If the file +.I .hushlogin +exists, then a "quiet" login is performed (this disables the checking of +the checking of mail and the printing of the last login time and message of +the day). Otherwise, if +.I /var/adm/lastlog +exists, the last login time is printed (and the current login is recorded). + +Random administrative things, such as setting the UID and GID of the tty +are performed. The TERM environment variable is preserved, if it exists +(other environment variables are preserved if the +.B \-p +option is used). Then the HOME, PATH, SHELL, TERM, MAIL, and LOGNAME +environment variables are set. PATH defaults to +.I /usr/local/bin:/bin:/usr/bin:. +for normal users, and to +.I /sbin:/bin:/usr/sbin:/usr/bin +for root. Last, if this is not a "quiet" login, the message of the day is +printed and the file with the user's name in +.I /usr/spool/mail +will be checked, and a message printed if it has non-zero length. + +The user's shell is then started. If no shell is specified for the user in +.BR /etc/passwd , +then +.B /bin/sh +is used.

If the +.B single +option is used, or if the file +.I /etc/singleboot +exists, then single user mode will be entered, by starting +.IR /bin/sh . +If the file +.I /etc/securesingle +exists, then the root password will be required to start single user mode. +If the root password does not exist, or if +.I /etc/passwd +does not exist, the checking of the password will be skipped. + +If the file +.I /etc/TZ +exists, then the contents of that file will be read, and used to set the TZ +environment variable for each process started by +.BR simpleinit . +This "feature" is only available if it's configured at compile-time. It's +not normally needed. + +After single user mode is terminated, the +.I /etc/rc +file is executed, and the information in +.I /etc/inittab +will be used to start processes. + +While +.B init +is running, several signals are trapped, with special action taken. Since +.B init +has PID 1, sending signals to the +.B init +process is easy with the +.BR kill (1) +command. + +If +.B init +catches a SIGHUP (hangup) signal, the +.I /etc/inittab +will be read again. + +If +.B init +catches a SIGTSTP (terminal stop) signal, no more processes will be +spawned. This is a toggle, which is reset is +.B init +catches another SIGTSTP signal. + +If +.B init +catches a SIGINT (interrupt) signal, +.B init +will sync a few times, and try to start +.IR reboot . +Failing this, +.B init +will execute the system +.BR reboot (2) +call. Under Linux, it is possible to configure the Ctrl-Alt-Del sequence +to send a signal to +.B init +instead of rebooting the system. +.SH "THE INITTAB FILE" +Because of the number of init programs which are appearing in the Linux +community, the documentation for the +.I /etc/inittab +file, which is usually found with the +.BR inittab (5) +man page, is presented here: + +The format is + +.RS +.B "ttyline:termcap-entry:getty-command" +.RE + +An example is as follows: + +.nf +.RS +tty1:console:/sbin/getty 9600 tty1 +tty2:console:/sbin/getty 9600 tty2 +tty3:console:/sbin/getty 9600 tty3 +tty4:console:/sbin/getty 9600 tty4 +# tty5:console:/sbin/getty 9600 tty5 +# ttyS1:dumb:/sbin/getty 9600 ttyS1 +# ttyS2:dumb:/sbin/getty -m -t60 2400 ttyS2 +.RE +.fi + +Lines beginning with the +.B # +character are treated as comments.

For example, in the standard +.BR DEVINFO , +"generic" is a batch. +.TP +.RI "block " device-spec +This defines one or more block devices. +.TP +.RI "char " device-spec +This defines one or more character devices. +.LP +Here is a sample +.IR device-spec : +.RS +.nf +(std, 1) { + mem (kmem) : 1 + null (public) : 3 + core -> "/proc/kcore" +} +.fi +.RE +.LP +This example defines a group of devices called "std", with major +number 1. Running +.B "\"MAKEDEV std\"" +will create all the devices in the group; running, for example, +.B "\"MAKEDEV null\"" +would make just the one device "null". +.LP +It is possible to specify, instead of just "std", something like +"std=foo". In this case, the stuff on the right-hand side of the +equals sign specifies a name from +.BR /proc/devices , +and the major number will be retrieved from there if present. If an +entry from +.BR /proc/devices +is specified, the explicit major number may be omitted. In this case, +if the number is not found in /proc/devices, attempts to create the +device will be rejected. +.LP +Inside the braces is a list of specific devices. The name in +parenthesis is the "class" - this is something specified in +.B MAKEDEV.cfg +(q.v.) that determines the ownership and permissions of the special +file created. In the above example, the device "mem" was set to have +the class "kmem", but "null" was set to be "public". Ordinarily you'd +define "public" to be mode 666, but "kmem" to be mode 660 and owned by +group kmem. The number after the colon is the minor number for this +particular device \- for instance, 3 for "null". +.LP +You may also specify a symbolic link with "->". For instance, above, +"core" was made a link to +.BR /proc/kcore . +Note that names may contain any characters, but names that contain +things other than alphanumerics, dash, and underscore should be put in +double quotes. +.LP +An entire range of devices can be created: you may specify a range of +numbers in brackets, like this: +.RS +.nf + +tty[1-8] (tty) : 1 + +.fi +.RE +This creates tty1\-tty8 with minor device numbers starting with 1. +If you specify the range in hex (prefixed by 0x) the device names will +be created numbered in hex, as is normal for ptys. The range may +appear inside the name string, but there may only be one range. +.LP +There is a special syntax for creating the entire banks of devices for +a hard drive: +.RS +.nf + + hd[a-d] 8/64 + +.fi +.RE +What this means is as follows: create hda, and 8 partitions on hda +(hda1 through hda8), starting with minor number 0. Then create hdb, +and 8 partitions, starting with minor number 64. Then hdc, etc., with +minor number 64*2 = 128. And so forth. These are automatically placed +in the class "disk". The necessary groups and batches are created so +you can ask +.B MAKEDEV +to create "hd" or "hda" or "hda1" and expect it to do the correct +thing. +.LP +Note that simple arithmetic is permitted for specifying the minor +device number, as this often makes things much clearer and less likely +to be accidentally broken. +.SH "SEE ALSO" +.BR MAKEDEV (8), +.BR MAKEDEV.cfg (5) diff --git a/makedev-1.4.1/makedev.c b/makedev-1.4.1/makedev.c new file mode 100644 index 00000000..59f16e0d --- /dev/null +++ b/makedev-1.4.1/makedev.c @@ -0,0 +1,2296 @@ +/* + * makedev.c: Generate /dev entries + * + * Based on the MAKEDEV shell script, version 2.0, distributed with + * util-linux 1.10 and written by Nick Holloway. + * + * A number of bugs were fixed, and some additional features added. + * Written 10-Dec-94 by David A.

A year that occurs +before the reformation is determined to be a leap year if its modulo of +4 equals zero. But after the reformation, a year is only a leap year if +its modulo of 4 equals zero and its modulo of 100 does not. Of course, +there is an exception for these century years. If the modulo of 400 equals +zero, then the year is a leap year anyway. This is, in fact, what the +gregorian reformation was all about (a bit of error in the old algorithm +that caused the calendar to be inaccurate.) + +Once we have the day in year for the first of the month in question, the +rest is trivial. diff --git a/misc-utils/README.hostname b/misc-utils/README.hostname new file mode 100644 index 00000000..1e82b8cf --- /dev/null +++ b/misc-utils/README.hostname @@ -0,0 +1,29 @@ + +You may ask "Why another version of the hostname command?".

Supercedes the [u]mount +previously available in the bootutils-0.1 collection. + +Fixed a minor bug in canonicalise(). + +mount/umount/swapon/swapoff(8) for Linux 0.99.6 +=============================================== + +Here is a minor update to the previous version that fixes +a longstanding "off by one" bug in parsing fs-specific +options. No other real changes. + +mount/umount/swapon/swapoff(8) for Linux 0.99.2 +=============================================== + +Here is a new version of Doug Quale's mount/umount package that +includes support for mounting and unmount NFS filesystems. It is +still possible to compile it without NFS support by modifying the +Makefile. Even if you don't have rpcgen, but do have libc-4.2 +you can "cp -p" the pre-generated files in the rpcsvc directory +into the mount source directory. + +The primary difference besides the actual NFS mounting code is that +mount understands hostname:/path syntax for the "device" as well as +the new keyword "none" which is useful for the proc filesystem. Also, +umount had to be trained to specify the mount-point instead of the +device when unmounting such filesystems. For compatibility, +filesystems with true devices are unmounted using their device name +which will still work with older kernels. However, all umounts could +just as well be done by specifying the mount point instead of the +device. + +Other changes since the beta NFS mount are: + +* incorportated H.J. Lu's changes for mtab permissions and errno handling +* corrected the error message for unhandled errors from mount and umount +* improved (a little :-) the reporting of handled mount and umount errors +* added the ability to NFS mount from a IP address as well as a hostname +* added a string error message instead of numeric for failed NFS mounts +* changed 32 to _NSIG when setting all signals (should be using sigismember) +* eliminated the obsolete HAVE_MOUNT5 and HAVE_SWAPOFF ifdefs +* added support for the sync and async mount options +* added the noauto option for fstab entries that shouldn't get mounted with -a +* changed mount -a to check the mtab for already mounted filesystems +* eliminated a few new warning messages from gcc 2.3.3 +* wrote an nfs man page + +Features still missing: + +* ability to background NFS mounts that have timed out +* notify the NFS server of umounts (but addr=ip-addr support is in there) +* add the possibility of interrupting an in-progress mount +* man pages for the other Linux filesystem types + +Rick Sladkey +jrs@world.std.com +=============================================== +mount/umount/swapon/swapoff(8) for Linux 0.98.5 +=============================================== + +This version fixed the umask of root. fchmod () is called +before close /etc/mtab. This version should work with +0.97.3 or above, although I only tested it under 0.98.5. +I also fixed the error report. + +H.J. Lu +hlu@eecs.wsu.edu +11/25/92 +=============================================== +mount/umount/swapon/swapoff(8) for Linux 0.97.3 +=============================================== + +The most significant improvement over the first release is the repair of +at least a half dozen really dumb bugs, mostly involving null pointers. +These bugs caused frequent core dumps and really made the code unusable. + +Some race conditions in the lock handling code have been removed. + +Swapoff is available for 0.97.3 and later kernels. + +Swapon supports multiple swap files. In particular, swapon -a will try +to enable swapping on all the swap entries in /etc/fstab. + +File system specific mount options are now supported. This is of particular +utility with Werner Almesberger's msdos fs. + +Umount -a now reads /etc/mtab instead of /etc/fstab (thanks to David +Engel for a valuable discussion on this and other points). In addition, +it umounts the entries in reverse order, ensuring that it tries to umount +/usr/spool before /usr, for instance. + +Mount will now print mtab for ordinary users as well as for the superuser. +Several people pointed out this deficiency, and it was a real no-brainer +that broke it in the first release. + +Thanks to Linus, for another great release. 0.97.3 compiled the first time +out and is working flawlessly.

This is useful to show +disk partitions which are currently unused. + +The fourth field, +.RI ( fs_mntops ), +describes the mount options associated with the filesystem. + +It is formatted as a comma separated list of options. It contains at least +the type of mount plus any additional options appropriate to the filesystem +type. For documentation on all of the available options, see +.BR mount (8). + +The fifth field, +.RI ( fs_freq ), +is used for these filesystems by the +.BR dump (8) +command to determine which filesystems need to be dumped. If the fifth +field is not present, a value of zero is returned and +.B dump +will assume that the filesystem does not need to be dumped. + +The sixth field, +.RI ( fs_passno ), +is used by the +.BR fsck (8) +program to determine the order in which filesystem checks are done at +reboot time. The root filesystem should be specified with a +.I fs_passno +of 1, and other filesystems should have a +.I fs_passno +of 2. Filesystems within a drive will be checked sequentially, but +filesystems on different drives will be checked at the same time to utilize +parallelism available in the hardware. If the sixth field is not present +or zero, a value of zero is returned and +.B fsck +will assume that the filesystem does not need to be checked. + +The proper way to read records from +.B fstab +is to use the routines +.BR getmntent (3). +.SH FILES +.I /etc/fstab +The file +.B fstab +resides in +.IR /etc . +.SH BUGS +Linux does not, currently, support the special fields for +.BR dump " and " fsck . + +The documentation in +.BR mount (8) +is often more up-to-date. +.SH "SEE ALSO" +.BR getmntent "(3), " mount "(8), " swapon (8) +.SH HISTORY +The +.B fstab +file format appeared in 4.0BSD. diff --git a/mount/fstab.c b/mount/fstab.c new file mode 100644 index 00000000..95b0879e --- /dev/null +++ b/mount/fstab.c @@ -0,0 +1,92 @@ +/* /home/faith/cvs/util-linux/mount/fstab.c,v 1.1.1.1 1995/02/22 19:09:21 faith Exp */ + +#include "fstab.h" +#include <stdio.h> + +#define streq(s, t) (strcmp ((s), (t)) == 0) + +/* These routines are superceded by mntent(3), but I use them for + convenience.

After the first timeout, +the timeout is doubled after each successive timeout until a maximum +timeout of 60 seconds is reached or the enough retransmissions +have occured to cause a major timeout. Then, if the filesystem +is hard mounted, each new timeout cascade restarts at twice the +initial value of the previous cascade, again doubling at each +retransmission. The maximum timeout is always 60 seconds. +Better overall performance may be achieved by increasing the +timeout when mounting on a busy network, to a slow server, or through +several routers or gateways. +.TP 1.5i +.I retrans=n +The number of minor timeouts and retransmissions that must occur before +a major timeout occurs. The default is 3 timeouts. When a major timeout +occurs, the file operation is either aborted or a "server not responding" +message is printed on the console. +.TP 1.5i +.I acregmin=n +The minimum time in seconds that attributes of a regular file should +be cached before requesting fresh information from a server. +The default is 3 seconds. +.TP 1.5i +.I acregmax=n +The maximum time in seconds that attributes of a regular file can +be cached before requesting fresh information from a server. +The default is 60 seconds. +.TP 1.5i +.I acdirmin=n +The minimum time in seconds that attributes of a directory should +be cached before requesting fresh information from a server. +The default is 30 seconds. +.TP 1.5i +.I acdirmax=n +The maximum time in seconds that attributes of a directory can +be cached before requesting fresh information from a server. +The default is 60 seconds. +.TP 1.5i +.I actimeo=n +Using actimeo sets all of +.I acregmin, +.I acregmax, +.I acdirmin, +and +.I acdirmax +to the same value. +There is no default value. +.TP 1.5i +.I retry=n +The number of times to retry a backgrounded NFS mount operation +before giving up. +The default value is 10000 times. +.TP 1.5i +.I namlen=n +When an NFS server does not support version two of the +RPC mount protocol, this option can be used to specify +the maximum length of a filename that is supported on +the remote filesystem.

This allows +an NFS filesystem to properly support the POSIX pathconf +command by querying the mount server for the maximum length +of a filename.

See the +specific sections on each type of resource for details. + + Each type of mechanism provides a "get", "ctl" and one or more "op" +system calls that allow the user to create or procure the resource +(get), define its behaviour or destroy it (ctl) and manipulate the +resources (op). + +The "get" system calls +---------------------- + + The `get' call typically takes a KEY and returns a numeric ID that +is used for further access. The ID is an index into the resource table. +A sequence number is maintained and incremented when a resource is +destroyed so that acceses using an obselete ID is likely to fail. + + The user also specifies the permissions and other behaviour +charecteristics for the current access. The flags are or-ed with the +permissions when invoking system calls as in: + msgflg = IPC_CREAT | IPC_EXCL | 0666; + id = msgget (key, msgflg); + + * `key' : IPC_PRIVATE => new instance of resource is initialized. + + * `flags' : + IPC_CREAT : resource created for KEY if it does not exist. + + IPC_CREAT | IPC_EXCL : fail if resource exists for KEY. + + * returns : an identifier used for all further access to the + resource. + + Note that IPC_PRIVATE is not a flag but a special `key' that ensures +(when the call is successful) that a new resource is created. + + Use of IPC_PRIVATE does not make the resource inaccessible to other +users. For this you must set the access permissions appropriately. + + There is currently no way for a process to ensure exclusive access +to a resource. IPC_CREAT | IPC_EXCL only ensures (on success) that a new +resource was initialized. It does not imply exclusive access. + +See Also : *Note msgget::, *Note semget::, *Note shmget::. + +The "ctl" system calls +---------------------- + + Provides or alters the information stored in the structure that +describes the resource indexed by ID. + + #include <sys/msg.h> + struct msqid_ds buf; + err = msgctl (id, IPC_STAT, &buf); + if (err) + !$#%* + else + printf ("creator uid = %d\n", buf.msg_perm.cuid); + .... + +Commands supported by all `ctl' calls: + * IPC_STAT : read info on resource specified by id into user + allocated buffer.

This should be +transparent to the user. + +Semaphore `undo' requests +------------------------- + + There is one sem_undo structure associated with a process for each +semaphore which was altered (with an undo request) by the process. +`sem_undo' structures are freed only when the process exits. + + One major cause for unhappiness with the undo mechanism is that it +does not fit in with the notion of having an atomic set of operations +on an array. The undo requests for an array and each semaphore therein +may have been accumulated over many `semop' calls. Thus use the undo +mechanism with private semaphores only. + + Should the process sleep in `exit' or should all undo operations be +applied with the IPC_NOWAIT flag in effect? Currently those undo +operations which go through immediately are applied and those that +require a wait are ignored silently. + +Shared memory, `malloc' and the `brk'. +-------------------------------------- + + Note that since this section was written the implementation was +changed so that non-specific attaches are done in the region 1G - 1.5G. +However much of the following is still worth thinking about so I left +it in. + + On many systems, the shared memory is allocated in a special region +of the address space ... way up somewhere. As mentioned earlier, this +implementation attaches shared segments at the lowest possible address. +Thus if you plan to use `malloc', it is wise to malloc a large space +and then proceed to attach the shared segments. This way malloc sets +the brk sufficiently above the region it will use. + + Alternatively you can use `sbrk' to adjust the `brk' value as you +make shared memory attaches. The implementation is not very smart about +selecting attach addresses. Using the system default addresses will +result in fragmentation if detaches do not occur in the reverse +sequence as attaches. + + Taking control of the matter is probably best. The rule applied is +that attaches are allowed in unmapped regions other than in the text +space (see <a.out.h>). Also remember that attach addresses and segment +sizes are multiples of PAGE_SIZE. + + One more trap (I quote Bruno on this). If you use malloc() to get +space for your shared memory (ie. to fix the `brk'), you must ensure you +get an unmapped address range. This means you must mallocate more memory +than you had ever allocated before. Memory returned by malloc(), used, +then freed by free() and then again returned by malloc is no good. +Neither is calloced memory. + + Note that a shared memory region remains a shared memory region until +you unmap it. Attaching a segment at the `brk' and calling malloc after +that will result in an overlap of what malloc thinks is its space with +what is really a shared memory region. For example in the case of a +read-only attach, you will not be able to write to the overlapped +portion. + +Fork, exec and exit +------------------- + + On a fork, the child inherits attached shared memory segments but +not the semaphore undo information. + + In the case of an exec, the attached shared segments are detached. +The sem undo information however remains intact. + + Upon exit, all attached shared memory segments are detached. The +adjust values in the undo structures are added to the relevant semvals +if the operations are permitted.

After use the resource +must be explicitly destroyed by the creator or owner.@refill + +A resource is identified by a numeric @var{id}. Typically a creator +defines a @var{key} that may be used to access the resource. The user +process may then use this @var{key} in the @dfn{get} system call to obtain +the @var{id} for the corresponding resource. This @var{id} is then used for +all further access. A library call @dfn{ftok} is provided to translate +pathnames or strings to numeric keys.@refill + +There are system and implementation defined limits on the number and +sizes of resources of any given type. Some of these are imposed by the +implementation and others by the system administrator +when configuring the kernel (@xref{msglimits}, @xref{semlimits}, +@xref{shmlimits}).@refill + +There is an @code{msqid_ds}, @code{semid_ds} or @code{shmid_ds} struct +associated with each message queue, semaphore array or shared segment. +Each ipc resource has an associated @code{ipc_perm} struct which defines +the creator, owner, access perms ..etc.., for the resource. +These structures are detailed in the following sections.@refill + + + +@node example, perms, Overview, Overview +@section example + +Here is a code fragment with pointers on how to use shared memory. The +same methods are applicable to other resources.@refill + +In a typical access sequence the creator allocates a new instance +of the resource with the @code{get} system call using the IPC_CREAT +flag.@refill + +@noindent creator process:@* + +@example +#include <sys/shm.h> +int id; +key_t key; +char proc_id = 'C'; +int size = 0x5000; /* 20 K */ +int flags = 0664 | IPC_CREAT; /* read-only for others */ + +key = ftok ("~creator/ipckey", proc_id); +id = shmget (key, size, flags); +exit (0); /* quit leaving resource allocated */ +@end example + +@noindent +Users then gain access to the resource using the same key.@* +@noindent +Client process: +@example +#include <sys/shm.h> +char *shmaddr; +int id; +key_t key; +char proc_id = 'C'; + +key = ftok ("~creator/ipckey", proc_id); + +id = shmget (key, 0, 004); /* default size */ +if (id == -1) + perror ("shmget ..."); + +shmaddr = shmat (id, 0, SHM_RDONLY); /* attach segment for reading */ +if (shmaddr == (char *) -1) + perror ("shmat ..."); + +local_var = *(shmaddr + 3); /* read segment etc. */ + +shmdt (shmaddr); /* detach segment */ +@end example + +@noindent +When the resource is no longer needed the creator should remove it.@* +@noindent +Creator/owner process 2: +@example +key = ftok ("~creator/ipckey", proc_id) +id = shmget (key, 0, 0); +shmctl (id, IPC_RMID, NULL); +@end example + + +@node perms, syscalls, example, Overview +@section Permissions + +Each resource has an associated @code{ipc_perm} struct which defines the +creator, owner and access perms for the resource.@refill + +@example +struct ipc_perm + key_t key; /* set by creator */ + ushort uid; /* owner euid and egid */ + ushort gid; + ushort cuid; /* creator euid and egid */ + ushort cgid; + ushort mode; /* access modes in lower 9 bits */ + ushort seq; /* sequence number */ +@end example + +The creating process is the default owner. The owner can be reassigned +by the creator and has creator perms. Only the owner, creator or super-user +can delete the resource.@refill + +The lowest nine bits of the flags parameter supplied by the user to the +system call are compared with the values stored in @code{ipc_perms.mode} +to determine if the requested access is allowed. In the case +that the system call creates the resource, these bits are initialized +from the user supplied value.@refill + +As for files, access permissions are specified as read, write and exec +for user, group or other (though the exec perms are unused). For example +0624 grants read-write to owner, write-only to group and read-only +access to others.@refill + +For shared memory, note that read-write access for segments is determined +by a separate flag which is not stored in the @code{mode} field. +Shared memory segments attached with write access can be read.@refill + +The @code{cuid}, @code{cgid}, @code{key} and @code{seq} fields +cannot be changed by the user.@refill + + + +@node syscalls, Messages, perms, Overview +@section IPC system calls + +This section provides an overview of the IPC system calls. See the +specific sections on each type of resource for details.@refill + +Each type of mechanism provides a @dfn{get}, @dfn{ctl} and one or more +@dfn{op} system calls that allow the user to create or procure the +resource (get), define its behaviour or destroy it (ctl) and manipulate +the resources (op).@refill + + + +@subsection The @dfn{get} system calls + +The @code{get} call typically takes a @var{key} and returns a numeric +@var{id} that is used for further access. +The @var{id} is an index into the resource table. A sequence +number is maintained and incremented when a resource is +destroyed so that acceses using an obselete @var{id} is likely to fail.@refill + +The user also specifies the permissions and other behaviour +charecteristics for the current access. The flags are or-ed with the +permissions when invoking system calls as in:@refill +@example +msgflg = IPC_CREAT | IPC_EXCL | 0666; +id = msgget (key, msgflg); +@end example +@itemize @bullet +@item +@code{key} : IPC_PRIVATE => new instance of resource is initialized. +@item +@code{flags} : +@itemize @asis +@item +IPC_CREAT : resource created for @var{key} if it does not exist. +@item +IPC_CREAT | IPC_EXCL : fail if resource exists for @var{key}. +@end itemize +@item +returns : an identifier used for all further access to the resource. +@end itemize + +Note that IPC_PRIVATE is not a flag but a special @code{key} +that ensures (when the call is successful) that a new resource is +created.@refill + +Use of IPC_PRIVATE does not make the resource inaccessible to other +users. For this you must set the access permissions appropriately.@refill + +There is currently no way for a process to ensure exclusive access to a +resource. IPC_CREAT | IPC_EXCL only ensures (on success) that a new +resource was initialized. It does not imply exclusive access.@refill + +@noindent +See Also : @xref{msgget}, @xref{semget}, @xref{shmget}.@refill + + + +@subsection The @dfn{ctl} system calls + +Provides or alters the information stored in the structure that describes +the resource indexed by @var{id}.@refill + +@example +#include <sys/msg.h> +struct msqid_ds buf; +err = msgctl (id, IPC_STAT, &buf); +if (err) + !$#%* +else + printf ("creator uid = %d\n", buf.msg_perm.cuid); + .... +@end example + +@noindent +Commands supported by all @code{ctl} calls:@* +@itemize @bullet +@item +IPC_STAT : read info on resource specified by id into user allocated +buffer.

The undo requests for an array and each +semaphore therein may have been accumulated over many @code{semop} +calls. Thus use the undo mechanism with private semaphores only.@refill + +Should the process sleep in @code{exit} or should all undo +operations be applied with the IPC_NOWAIT flag in effect? +Currently those undo operations which go through immediately are +applied and those that require a wait are ignored silently.@refill + +@subsection Shared memory, @code{malloc} and the @code{brk}. +Note that since this section was written the implementation was +changed so that non-specific attaches are done in the region +1G - 1.5G. However much of the following is still worth thinking +about so I left it in. + +On many systems, the shared memory is allocated in a special region +of the address space ... way up somewhere. As mentioned earlier, +this implementation attaches shared segments at the lowest possible +address. Thus if you plan to use @code{malloc}, it is wise to malloc a +large space and then proceed to attach the shared segments. This way +malloc sets the brk sufficiently above the region it will use.@refill + +Alternatively you can use @code{sbrk} to adjust the @code{brk} value +as you make shared memory attaches. The implementation is not very +smart about selecting attach addresses. Using the system default +addresses will result in fragmentation if detaches do not occur +in the reverse sequence as attaches.@refill + +Taking control of the matter is probably best. The rule applied +is that attaches are allowed in unmapped regions other than +in the text space (see <a.out.h>). Also remember that attach addresses +and segment sizes are multiples of PAGE_SIZE.@refill + +One more trap (I quote Bruno on this). If you use malloc() to get space +for your shared memory (ie. to fix the @code{brk}), you must ensure you +get an unmapped address range. This means you must mallocate more memory +than you had ever allocated before. Memory returned by malloc(), used, +then freed by free() and then again returned by malloc is no good. +Neither is calloced memory.@refill + +Note that a shared memory region remains a shared memory region until +you unmap it. Attaching a segment at the @code{brk} and calling malloc +after that will result in an overlap of what malloc thinks is its +space with what is really a shared memory region. For example in the case +of a read-only attach, you will not be able to write to the overlapped +portion.@refill + + +@subsection Fork, exec and exit + +On a fork, the child inherits attached shared memory segments but +not the semaphore undo information.@refill + +In the case of an exec, the attached shared segments are detached. +The sem undo information however remains intact.@refill + +Upon exit, all attached shared memory segments are detached. +The adjust values in the undo structures are added to the relevant semvals +if the operations are permitted. Disallowed operations are ignored.@refill + + +@subsection Other Features + +These features of the current implementation are +likely to be modified in the future. + +The SHM_LOCK and SHM_UNLOCK flag are available (super-user) for use with the +@code{shmctl} call to prevent swapping of a shared segment. The user +must fault in any pages that are required to be present after locking +is enabled. + +The IPC_INFO, MSG_STAT, MSG_INFO, SHM_STAT, SHM_INFO, SEM_STAT, SEMINFO +@code{ctl} calls are used by the @code{ipcs} program to provide information +on allocated resources. These can be modified as needed or moved to a proc +file system interface. + + +@sp 3 +Thanks to Ove Ewerlid, Bruno Haible, Ulrich Pegelow and Linus Torvalds +for ideas, tutorials, bug reports and fixes, and merriment.

If the name of the map file ends with `.gz' it +is decompressed on the fly. + +.TP +.RB -p " pro-file" +Specify a different profiling buffer, which by default is +.B /proc/profile. +Using a different pro-file is useful if you want to `freeze' the +kernel profiling at some time and read it later. The +.B /proc/profile +file can be copied using `cat' or `cp'. If the name of the pro-file +ends by `.gz' it is decompressed on the fly. The pro-file is such that +.B gzip +shrinks it by 50-100 times. + +.TP +.B -i +Info.

It will usually have the following form: +.BR /dev/cua[0-3] . + +If no parameters are specified, +.B setserial +will print out the port type (i.e., 8250, 16450, 16550, 16550A), the +hardware I/O port, the hardware IRQ line, its "baud base," and some of +its operational flags. + +If the +.B \-g +option is given, the arguments to setserial are interpreted as a list +of devices for which the characteristics of those devices should be +printed. + +Without the +.B \-g +option, the first argument to setserial is interpreted as the device +to be modified or characteristics to be printed, and any additional +arguments are interpreted as parameters which should be assigned +to that serial device. + +For the most part, superuser privilege is required to set the +configuration parameters of a serial port. A few serial port parameters +can be set by normal users, however, and these will be noted as +exceptions in this manual page. + +.SH OPTIONS +.B Setserial +accepts the following options: + +.TP +.B \-a +When reporting the configuration of a serial device, print all +available information. +.TP +.B \-b +When reporting the configuration of a serial device, print a summary +of the device's configuration, which might be suitable for printing +during the bootup process, during the /etc/rc script. +.TP +.B \-q +Be quiet. +.B Setserial +will print fewer lines of output. +.TP +.B \-v +Be verbose. +.B Setserial +will print additional status output. +.TP +.B \-V +Display version and exit. +.TP +.B \-W +Do wild interrupt initialization and exit. + +.SH PARAMETERS +The following parameters can be assigned to a serial port. + +All argument values are assumed to be in decimal unless preceeded by "0x". + +.TP +.BR port " port_number" +The +.B port +option sets the I/O port, as described above. +.TP +.BR irq " irq_number" +The +.B irq +option sets the hardware IRQ, as described above. +.TP +.BR uart " uart_type" +This option is used to set the UART type. The permitted types are +.BR none , +8250, 16450, 16550, and 16550A. Since the 8250 and 16450 UARTS do not have +FIFO's, and since the original 16550 have bugs which make the FIFO's unusable, +the FIFO will only be used on chips identifiied as 16550A UARTs. +Setting the UART type to 8250, 16450, or 16550 will enable the serial +port without trying to use the FIFO. Using UART type +.B none +will disable the port. + +Some internal modems are billed as having a "16550A UART with a 1k +buffer". This is a lie. They do not have really have a 16550A +compatible UART; instead what they have is a 16450 compatible UART +with a 1k receive buffer to prevent receiver overruns. This is +important, because they do not have a transmit FIFO. Hence, they are +not compatible with a 16550A UART, and the autoconfiguration process +will correctly identify them as 16450's. If you attempt to override +this using the +.B uart +parameter, you will see dropped characters during file transmissions. +These UART's usually have other problems: the +.B skip_test +parameter also often must be specified. +.TP +.B autoconfig +When this parameter is given, +.B setserial +will ask the kernel to attempt to automatically configure the serial +port. The I/O port must be correctly set; the kernel will attempt to +determine the UART type, and if the +.B auto_irq +parameter is set, Linux will attempt to automatically determine the +IRQ. The +.B autoconfigure +parameter should be given after the +.BR port , auto_irq ", and" skip_test +parameters have been specified. +.TP +.B auto_irq +During autoconfiguration, try to determine the IRQ. This feature is +not guaranteed to always produce the correct result; some hardware +configurations will fool the Linux kernel. It is generally safer not +to use the +.B auto_irq +feature, but rather to specify the IRQ to be used explicitly, using +the +.B irq +parameter. +.TP +.B ^auto_irq +During autoconfiguration, do +.I not +try to determine the IRQ. +.TP +.B skip_test +During autoconfiguration, skip the UART test. Some internal modems do +not have National Semiconductor compatible UART's, but have cheap +imitations instead. Some of these cheasy imitations UART's do not +fully support the loopback detection mode, which is used by the kernel +to make sure there really is a UART at a particular address before +attempting to configure it. So for certain internal modems you will +need to specify this parameter so Linux can initialize the UART +correctly. +.TP +.B ^skip_test +During autoconfiguration, do +.I not +skip the UART test. +.TP +.BR baud_base " baud_base" +This option sets the base baud rate, which is the clock frequency divided +by 16. Normally this value is 115200, which is also the fastest baud +rate which the UART can support. +.TP +.B +spd_hi +Use 57.6kb when the application requests 38.4kb. +This parameter may be specified by a non-privileged user. +.TP +.B spd_vhi +Use 115kb when the application requests 38.4kb. +This parameter may be specified by a non-privileged user. +.TP +.B spd_cust +Use the custom divisor to set the speed when the application requests +38.4kb. In this case, the baud rate is the +.B baud_base +divided by the +.BR divisor . +This parameter may be specified by a non-privileged user. +.TP +.B spd_normal +Use 38.4kb when the application requests 38.4kb. +This parameter may be specified by a non-privileged user. +.TP +.BR divisor " divisor" +This option sets the custom divison. This divisor will be used then the +.B spd_cust +option is selected and the serial port is set to 38.4kb by the +application. +This parameter may be specified by a non-privileged user. +.TP +.B sak +Set the break key at the Secure Attention Key. +.TP +.B ^sak +disable the Secure Attention Key. +.TP +.B fourport +Configure the port as an AST Fourport card. +.TP +.B ^fourport +Disable AST Fourport configuration. +.TP +.BR close_delay " delay" +Specify the amount of time, in hundredths of a second, that DTR should +remain low on a serial line after the callout device is closed, before +the blocked dialin device raises DTR again. The default value of this +option is 50, or a half-second delay. +.TP +.B session_lockout +Lock out callout port (/dev/cuaXX) accesses across different sessions. +That is, once a process has opened a port, do not allow a process with +a different session ID to open that port until the first process has +closed it. +.TP +.B ^session_lockout +Do not lock out callout port accesses across different sessions. +.TP +.B pgrp_lockout +Lock out callout port (/dev/cuaXX) accesses across different process groups. +That is, once a process has opened a port, do not allow a process in a +different process group to open that port until the first process has +closed it. +.TP +.B ^pgrp_lockout +Do not lock out callout port accesses across different process groups. +.TP +.B hup_notify +Notify a process blocked on opening a dial in line when a process has +finished using a callout line (either by closing it or by the serial +line being hung up) by returning EAGAIN to the open. + +The application of this parameter is for getty's which are blocked on +a serial port's dial in line. This allows the getty to reset the +modem (which may have had its configuration modified by the +application using the callout device) before blocking on the open again. +.TP +.B ^hup_notify +Do not notify a process blocked on opening a dial in line when the +callout device is hung up. +.TP +.B split_termios +Treat the termios settings used by the callout device and the termios +settings used by the dialin devices as separate. +.TP +.B ^split_termios +Use the same termios structure to store both the dialin and callout +ports. This is the default option. +.TP +.B callout_nohup +If this particular serial port is opened as a callout device, do not +hangup the tty when carrier detect is dropped. +.TP +.B ^callout_nohup +Do not skip hanging up the tty when a serial port is opened as a +callout device. Of course, the HUPCL termios flag must be enabled if +the hangup is to occur. +.SH CONSIDERATIONS OF CONFIGURING SERIAL PORTS +It is important to note that setserial merely tells the Linux kernel +where it should expect to find the I/O port and IRQ lines of a +particular serial port. It does *not* configure the hardware, the +actual serial board, to use a particular I/O port. In order to do +that, you will need to physically program the serial board, usually by +setting some jumpers or by switching some DIP switches. + +This section will provide some pointers in helping you decide how you +would like to configure your serial ports. + +The "standard MS-DOS" port associations are given below: + +.nf +.RS +/dev/ttyS0 (COM1), port 0x3f8, irq 4 +/dev/ttyS1 (COM2), port 0x2f8, irq 3 +/dev/ttyS2 (COM3), port 0x3e8, irq 4 +/dev/ttyS3 (COM4), port 0x2e8, irq 3 +.RE +.fi + +Due to the limitations in the design of the AT/ISA bus architecture, +normally an IRQ line may not be shared between two or more serial +ports. If you attempt to do this, one or both serial ports will +become unreliable if you try to use both simultaneously. This +limitation can be overcome by special multi-port serial port boards, +which are designed to share multiple serial ports over a single IRQ +line. Multi-port serial cards supported by Linux include the AST +FourPort, the Accent Async board, the Usenet Serial II board, the +Bocaboard BB-1004, BB-1008, and BB-2016 boards, and the HUB-6 serial +board. + +The selection of an alternative IRQ line +is difficult, since most of them are already used. The following table +lists the "standard MS-DOS" assignments of available IRQ lines: + +.nf +.RS +IRQ 3: COM2 +IRQ 4: COM1 +IRQ 5: LPT2 +IRQ 7: LPT1 +.RE +.fi + +Most people find that IRQ 5 is a good choice, assuming that there is +only one parallel port active in the computer. Another good choice is +IRQ 2 (aka IRQ 9); although this IRQ is sometimes used by network +cards, and very rarely VGA cards will be configured to use IRQ 2 as a +vertical retrace interrupt. If your VGA card is configured this way; +try to disable it so you can reclaim that IRQ line for some other +card. It's not necessary for Linux and most other Operating systems. + +The only other available IRQ lines are 3, 4, and 7, and these are +probably used by the other serial and parallel ports. (If your serial +card has a 16bit card edge connector, and supports higher interrupt +numbers, then IRQ 10, 11, 12, and 15 are also available.) + +On AT class machines, IRQ 2 is seen as IRQ 9, and Linux will interpret it +in this manner. + +IRQ's other than 2 (9), 3, 4, 5, 7, 10, 11, 12, and 15, should +.I not +be used, since they are assigned to other hardware and cannot, in general, +be changed. Here are the "standard" assignments: + +.nf +.RS +IRQ 0 Timer channel 0 +IRQ 1 Keyboard +IRQ 2 Cascade for controller 2 +IRQ 3 Serial port 2 +IRQ 4 Serial port 1 +IRQ 5 Parallel port 2 (Reserved in PS/2) +IRQ 6 Floppy diskette +IRQ 7 Parallel port 1 +IRQ 8 Real-time clock +IRQ 9 Redirected to IRQ2 +IRQ 10 Reserved +IRQ 11 Reserved +IRQ 12 Reserved (Auxillary device in PS/2) +IRQ 13 Math coprocessor +IRQ 14 Hard disk controller +IRQ 15 Reserved +.RE +.fi + + +.SH CAUTION +CAUTION: Using an invalid port can lock up your machine. +.SH FILES +.BR /etc/rc.local +.BR /etc/rc.serial +.SH "SEE ALSO" +.BR tty (4), +.BR ttys (4), +kernel/chr_drv/serial.c +.SH AUTHOR +The original version of setserial was written by Rick Sladkey +(jrs@world.std.com), and was modified by Michael K.

Without parameters, tells whether the device is using +interrups, and if so, which one. With parameters, sets the device +characteristics accordingly. The parameters are as follows: + +-i \fI<IRQ>\fP is the IRQ to use for the parallel port in question. If this +is set to something non-zero, -t and -c have no effect. If your port +does not use interrupts, this option will make printing stop. +.B tunelp -i 0 +restores non-interrupt driven (polling) action, and your printer should +work again. If your parallel port does support interrupts, +interrupt-driven printing should be somewhat faster and efficient, and +will probably be desireable. + +-t \fI<TIME>\fP is the amount of time in jiffies that the driver waits if the +printer doesn't take a character for the number of tries dictated by +the -c parameter. 10 is the default value. If you want fastest +possible printing, and don't care about system load, you may set this +to 0. If you don't care how fast your printer goes, or are printing +text on a slow printer with a buffer, then 500 (5 seconds) should be +fine, and will give you very low system load. This value generally +should be lower for printing graphics than text, by a factor of +approximately 10, for best performance. + +-c \fI<CHARS>\fP is the number of times to try to output a character to the +printer before sleeping for -t \fI<TIME>\fP. It is the number of times around +a loop that tries to send a character to the printer. 120 appears to +be a good value for most printers. 250 is the default, because there +are some printers that require a wait this long, but feel free to +change this. If you have a very fast printer like an HP laserjet 4, a +value of 10 might make more sense. If you have a \fIreally\fP old +printer, you can increase this farther. + +Setting -t \fI<TIME>\fP to 0 is equivalent to setting -c \fI<CHARS>\fP +to infinity. + +-w \fI<WAIT>\fP is the a busy loop counter for the strobe signal. While most +printers appear to be able to deal with an extremely short strobe, +some printers demand a longer one. Increasing this from the default +0 may make it possible to print with those printers. This may also +make it possible to use longer cables. + +-a [on|off] This is whether to abort on printer error -- the default +is not to. If you are sitting at your computer, you probably want to +be able to see an error and fix it, and have the printer go on +printing. On the other hand, if you aren't, you might rather that +your printer spooler find out that the printer isn't ready, quit +trying, and send you mail about it. The choice is yours. + +-o [on|off] This option is much like -a. It makes any open() of this +device check to see that the device is on-line and not reporting any +out of paper or other errors. This is the correct setting for most +versions of lpd. + +-C [on|off] This option adds extra ("careful") error checking. When +this option is on, the printer driver will ensure that the printer is +on-line and not reporting any out of paper or other errors before +sending data. This is particularly useful for printers that normally +appear to accept data when turned off. + +-s This option returns the current printer status, both as a +decimal number from 0..255, and as a list of active flags. When +this option is specified, -q off, turning off the display of the +current IRQ, is implied. + +-o, -C, and -s all require a Linux kernel version of 1.1.76 or later. + +-r This option resets the port. It requires a Linux kernel version of +1.1.80 or later. + +-q [on|off] This option sets printing the display of the current IRQ +setting. diff --git a/sys-utils/tunelp.c b/sys-utils/tunelp.c new file mode 100644 index 00000000..9005b172 --- /dev/null +++ b/sys-utils/tunelp.c @@ -0,0 +1,248 @@ +/****************************************************************************\ +* Copyright (C) 1992 by Michael K.

format_file +.Op Fl n Ar length +.Bk -words +.Op Fl s Ar skip +.Ek +.Ar file ... +.Sh DESCRIPTION +The hexdump utility is a filter which displays the specified files, or +the standard input, if no files are specified, in a user specified +format. +.Pp +The options are as follows: +.Bl -tag -width Fl +.It Fl b +.Em One-byte octal display . +Display the input offset in hexadecimal, followed by sixteen +space-separated, three column, zero-filled, bytes of input data, +in octal, per line. +.It Fl c +.Em One-byte character display . +Display the input offset in hexadecimal, followed by sixteen +space-separated, three column, space-filled, characters of input +data per line. +.It Fl d +.Em Two-byte decimal display. +Display the input offset in hexadecimal, followed by eight +space-separated, five column, zero-filled, two-byte units +of input data, in unsigned decimal, per line. +.It Fl e Ar format_string +Specify a format string to be used for displaying data. +.It Fl f Ar format_file +Specify a file that contains one or more newline separated format strings. +Empty lines and lines whose first non-blank character is a hash mark +.Pf ( Cm \&# ) +are ignored. +.It Fl n Ar length +Interpret only +.Ar length +bytes of input. +.It Fl o +.Em Two-byte octal display. +Display the input offset in hexadecimal, followed by eight +space-separated, six column, zero-filled, two byte quantities of +input data, in octal, per line. +.It Fl s Ar offset +Skip +.Ar offset +bytes from the beginning of the input. +By default, +.Ar offset +is interpreted as a decimal number. +With a leading +.Cm 0x +or +.Cm 0X , +.Ar offset +is interpreted as a hexadecimal number, +otherwise, with a leading +.Cm 0 , +.Ar offset +is interpreted as an octal number. +Appending the character +.Cm b , +.Cm k , +or +.Cm m +to +.Ar offset +causes it to be interpreted as a multiple of +.Li 512 , +.Li 1024 , +or +.Li 1048576 , +respectively. +.It Fl v +The +.Fl v +option causes hexdump to display all input data. +Without the +.Fl v +option, any number of groups of output lines, which would be +identical to the immediately preceding group of output lines (except +for the input offsets), are replaced with a line comprised of a +single asterisk. +.It Fl x +.Em Two-byte hexadecimal display. +Display the input offset in hexadecimal, followed by eight, space +separated, four column, zero-filled, two-byte quantities of input +data, in hexadecimal, per line. +.El +.Pp +For each input file, +.Nm hexdump +sequentially copies the input to standard output, transforming the +data according to the format strings specified by the +.Fl e +and +.Fl f +options, in the order that they were specified. +.Ss Formats +A format string contains any number of format units, separated by +whitespace. +A format unit contains up to three items: an iteration count, a byte +count, and a format. +.Pp +The iteration count is an optional positive integer, which defaults to +one. +Each format is applied iteration count times. +.Pp +The byte count is an optional positive integer. +If specified it defines the number of bytes to be interpreted by +each iteration of the format. +.Pp +If an iteration count and/or a byte count is specified, a single slash +must be placed after the iteration count and/or before the byte count +to disambiguate them. +Any whitespace before or after the slash is ignored. +.Pp +The format is required and must be surrounded by double quote +(" ") marks. +It is interpreted as a fprintf-style format string (see +.Xr fprintf 3 ) , +with the +following exceptions: +.Bl -bullet -offset indent +.It +An asterisk (*) may not be used as a field width or precision. +.It +A byte count or field precision +.Em is +required for each ``s'' conversion +character (unlike the +.Xr fprintf 3 +default which prints the entire string if the precision is unspecified). +.It +The conversion characters ``h'', ``l'', ``n'', ``p'' and ``q'' are +not supported. +.It +The single character escape sequences +described in the C standard are supported: +.Bd -ragged -offset indent -compact +.Bl -column <alert_character> +.It NUL \e0 +.It <alert character> \ea +.It <backspace> \eb +.It <form-feed> \ef +.It <newline> \en +.It <carriage return> \er +.It <tab> \et +.It <vertical tab> \ev +.El +.Ed +.El +.Pp +Hexdump also supports the the following additional conversion strings: +.Bl -tag -width Fl +.It Cm \&_a Ns Op Cm dox +Display the input offset, cumulative across input files, of the +next byte to be displayed. +The appended characters +.Cm d , +.Cm o , +and +.Cm x +specify the display base +as decimal, octal or hexadecimal respectively. +.It Cm \&_A Ns Op Cm dox +Identical to the +.Cm \&_a +conversion string except that it is only performed +once, when all of the input data has been processed. +.It Cm \&_c +Output characters in the default character set. +Nonprinting characters are displayed in three character, zero-padded +octal, except for

specified. +.Pp +The input is manipulated in ``blocks'', where a block is defined as the +largest amount of data specified by any format string. +Format strings interpreting less than an input block's worth of data, +whose last format unit both interprets some number of bytes and does +not have a specified iteration count, have the iteration count +incremented until the entire input block has been processed or there +is not enough data remaining in the block to satisfy the format string. +.Pp +If, either as a result of user specification or hexdump modifying +the iteration count as described above, an iteration count is +greater than one, no trailing whitespace characters are output +during the last iteration. +.Pp +It is an error to specify a byte count as well as multiple conversion

display some number of the zero bytes). +.Pp +Further output by such format strings is replaced by an equivalent +number of spaces. +An equivalent number of spaces is defined as the number of spaces +output by an +.Cm s +conversion character with the same field width +and precision as the original conversion character or conversion +string but with any +.Dq Li \&+ , +.Dq \&\ \& , +.Dq Li \&#

Daylight Savings Time conversion is applied." + This means that SVR2 can't deal with other (for example, Australian) + daylight savings time rules, or situations where more than two + time zone abbreviations are used in an area. + +* In SVR2, time conversion information is compiled into each program + that does time conversion. This means that when time conversion + rules change (as in the United States in 1987), all programs that + do time conversion must be recompiled to ensure proper results. + +* In SVR2, time conversion fails for near-minimum or near-maximum + time_t values when doing conversions for places that don't use GMT. + +* In SVR2, there's no tamper-proof way for a process to learn the + system's best idea of local wall clock. (This is important for + applications that an administrator wants used only at certain times-- + without regard to whether the user has fiddled the "TZ" environment + variable. While an administrator can "do everything in GMT" to get + around the problem, doing so is inconvenient and precludes handling + daylight savings time shifts--as might be required to limit phone + calls to off-peak hours.) + +* These functions can account for leap seconds, thanks to Bradley White + (bww@k.cs.cmu.edu). + +These are the changes that have been made to the SVR2 functions: + +* The "TZ" environment variable is used in generating the name of a file + from which time zone information is read (or is interpreted a la + POSIX); "TZ" is no longer constrained to be a three-letter time zone + name followed by a number of hours and an optional three-letter + daylight time zone name. The daylight saving time rules to be used + for a particular time zone are encoded in the time zone file; + the format of the file allows U.S., Australian, and other rules to be + encoded, and allows for situations where more than two time zone + abbreviations are used. + + It was recognized that allowing the "TZ" environment variable to + take on values such as "US/Eastern" might cause "old" programs + (that expect "TZ" to have a certain form) to operate incorrectly; + consideration was given to using some other environment variable + (for example, "TIMEZONE") to hold the string used to generate the + time zone information file name. In the end, however, it was decided + to continue using "TZ": it is widely used for time zone purposes; + separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; + and systems where "new" forms of "TZ" might cause problems can simply + use TZ values such as "EST5EDT" which can be used both by + "new" programs (a la POSIX) and "old" programs (as zone names and + offsets). + +* To handle places where more than two time zone abbreviations are used, + the functions "localtime" and "gmtime" set tzname[tmp->tm_isdst] + (where "tmp" is the value the function returns) to the time zone + abbreviation to be used. This differs from SVR2, where the elements + of tzname are only changed as a result of calls to tzset. + +* Since the "TZ" environment variable can now be used to control time + conversion, the "daylight" and "timezone" variables are no longer + needed or supported. (You can use a compile-time option to cause + these variables to be defined and to be set by "tzset"; however, their + values will not be used by "localtime.") + +* The "localtime" function has been set up to deliver correct results + for near-minimum or near-maximum time_t values. (A comment in the + source code tells how to get compatibly wrong results). + +* A function "tzsetwall" has been added to arrange for the system's + best approximation to local wall clock time to be delivered by + subsequent calls to "localtime." Source code for portable + applications that "must" run on local wall clock time should call + "tzsetwall();" if such code is moved to "old" systems that don't provide + tzsetwall, you won't be able to generate an executable program. + (These time zone functions also arrange for local wall clock time to be + used if tzset is called--directly or indirectly--and there's no "TZ" + environment variable; portable applications should not, however, rely + on this behavior since it's not the way SVR2 systems behave.) + +Points of interest to folks with Version 7 or BSD systems: + +* The BSD "timezone" function is not present in this package; + it's impossible to reliably map timezone's arguments (a "minutes west + of GMT" value and a "daylight saving time in effect" flag) to a + time zone abbreviation, and we refuse to guess. + Programs that in the past used the timezone function may now examine + tzname[localtime(&clock)->tm_isdst] to learn the correct time + zone abbreviation to use. Alternatively, use localtime(&clock)->tm_zone + if this has been enabled. + +* The BSD gettimeofday function is not used in this package; + this lets users control the time zone used in doing time conversions. + Users who don't try to control things (that is, users who do not set + the environment variable TZ) get the time conversion specified in the + file "/etc/zoneinfo/localtime"; see the time zone compiler writeup for + information on how to initialize this file. + +The functions that are conditionally compiled if STD_INSPIRED is defined should, +at this point, be looked on primarily as food for thought. They are not in +any sense "standard compatible"--some are not, in fact, specified in *any* +standard. They do, however, represent responses of various authors to +standardization proposals. + +Other time conversion proposals, in particular the one developed by folks at +Hewlett Packard, offer a wider selection of functions that provide capabilities +beyond those provided here. The absence of such functions from this package +is not meant to discourage the development, standardization, or use of such +functions. Rather, their absence reflects the decision to make this package +close to SVR2 (with the exceptions outlined above) to ensure its broad +acceptability. If more powerful time conversion functions can be standardized, +so much the better. diff --git a/time/africa b/time/africa new file mode 100644 index 00000000..a9786670 --- /dev/null +++ b/time/africa @@ -0,0 +1,603 @@ +# @(#)africa 7.6 + +# This data is by no means authoritative; if you think you know better, +# go ahead and edit the file (and please send any changes to +# tz@elsie.nci.nih.gov for general use in the future). + +# From Paul Eggert <eggert@twinsun.com> (November 18, 1993): +# +# A good source for time zone historical data outside the U.S. is +# Thomas G.

Do not exceed 14 characters or start with `-'. +# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'. +# Include at least one location per time zone rule set per country. +# One such location is enough. +# If a name is ambiguous, use a less ambiguous alternative; +# e.g. many cities are named San Jose and Georgetown, so +# prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'. +# Keep locations compact. Use cities or small islands, not countries +# or regions, so that any future time zone changes do not split +# locations into different time zones. E.g. prefer `Paris' +# to `France', since France has had multiple time zones. +# Use traditional English spelling, e.g. prefer `Rome' to `Roma', and +# prefer `Athens' to the true name (which uses Greek letters). +# The Posix file name restrictions encourage this rule. +# Use the most populous among locations in a country's time zone, +# e.g. prefer `Shanghai' to `Beijing'. Among locations with +# similar populations, pick the best-known location, +# e.g. prefer `Rome' to `Milan'. +# Use the singular form, e.g. prefer `Canary' to `Canaries'. +# Omit common suffixes like `_Islands' and `_City', unless that +# would lead to ambiguity. E.g. prefer `Cayman' to +# `Cayman_Islands' and `Guatemala' to `Guatemala_City', +# but prefer `Mexico_City' to `Mexico' because the country +# of Mexico has several time zones. +# Use `_' to represent a space. +# Omit `.' from abbreviations in names, e.g. prefer `St_Helena' +# to `St._Helena'. +# +# We typically use traditional English time zone abbreviations, +# and assume that applications translate them to other languages +# as part of the normal localization process. +# +# I made up the following time zone abbreviations; corrections are welcome! +# LMT Local Mean Time +# -2:00 CVT Cape Verde Time (no longer used) +# -1:00 AAT Atlantic Africa Time +# 0:00 WAT West Africa Time +# 1:00 CAT Central Africa Time +# 2:00 SAT South Africa Time +# 3:00 EAT East Africa Time +# 4:00 SMT Seychelles and Mascarene Time +# The final `T' is replaced by `ST' for summer time, e.g. `SAST'. +# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after. + + +# Algeria +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule Algeria 1911 only - Jan 1 0:00s 0 - +Rule Algeria 1916 only - Jun 14 23:00s 1:00 " DST" +Rule Algeria 1916 1919 - Oct Sun<=7 23:00s 0 - +Rule Algeria 1917 only - Mar 24 23:00s 1:00 " DST" +Rule Algeria 1918 only - Mar 9 23:00s 1:00 " DST" +Rule Algeria 1919 only - Mar 1 23:00s 1:00 " DST" +Rule Algeria 1920 only - Feb 14 23:00s 1:00 " DST" +Rule Algeria 1920 only - Oct 23 23:00s 0 - +Rule Algeria 1921 only - Mar 14 23:00s 1:00 " DST" +Rule Algeria 1921 only - Jun 21 23:00s 0 - +Rule Algeria 1939 only - Sep 11 23:00s 1:00 " DST" +Rule Algeria 1939 only - Nov 19 1:00 0 - +Rule Algeria 1944 1945 - Apr Mon<=7 2:00 1:00 " DST" +Rule Algeria 1944 only - Oct 8 2:00 0 - +Rule Algeria 1945 only - Sep 16 1:00 0 - +Rule Algeria 1971 only - Apr 25 23:00s 1:00 " DST" +Rule Algeria 1971 only - Sep 26 23:00s 0 - +Rule Algeria 1977 only - May 6 0:00 1:00 " DST" +Rule Algeria 1977 only - Oct 21 0:00 0 - +Rule Algeria 1978 only - Mar 24 1:00 1:00 " DST" +Rule Algeria 1978 only - Sep 22 3:00 0 - +Rule Algeria 1980 only - Apr 25 0:00 1:00 " DST" +Rule Algeria 1980 only - Oct 31 2:00 0 - +# Shanks gives 0:09 for Paris Mean Time; go with Whitman's more precise 0:09:05. +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 15 0:01 + 0:09:05 - PMT 1911 Mar 11 # Paris Mean Time + 0:00 Algeria WET%s 1940 Feb 25 2:00 + 1:00 Algeria MET%s 1946 Oct 7 + 0:00 - WET 1956 Jan 29 + 1:00 - MET 1963 Apr 14 + 0:00 Algeria WET%s 1977 Oct 21 + 1:00 Algeria MET%s 1979 Oct 26 + 0:00 Algeria WET%s 1981 May + 1:00 - MET + +# Angola +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Luanda 0:52:56 - LMT 1892 + 0:52 - LMT 1911 May 26 # Luanda Mean Time + 1:00 - CAT + +# Benin +# Whitman says they switched to 1:00 in 1946, not 1934; go with Shanks. +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Porto-Novo 0:10:28 - LMT 1912 + 0:00 - WAT 1934 Feb 26 + 1:00 - CAT + +# Botswana +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Gaborone 1:43:40 - LMT 1885 + 2:00 - SAT 1943 Sep 19 2:00 + 2:00 1:00 SAST 1944 Mar 19 2:00 + 2:00 - SAT + +# Burkina Faso +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Ouagadougou -0:06:04 - LMT 1912 + 0:00 - WAT + +# Burundi +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Bujumbura 1:57:28 - LMT 1890 + 2:00 - SAT + +# Cameroon +# Whitman says they switched to 1:00 in 1920; go with Shanks. +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Douala 0:38:48 - LMT 1912 + 1:00 - CAT + +# Cape Verde +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Atlantic/Cape_Verde -1:34:04 - LMT 1907 # Praia + -2:00 - CVT 1942 Sep + -2:00 1:00 CVST 1945 Oct 15 + -2:00 - CVT 1975 Nov 25 2:00 + -1:00 - AAT + +# Central African Republic +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Bangui 1:14:20 - LMT 1912 + 1:00 - CAT + +# Chad +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Ndjamena 1:00:12 - LMT 1912 + 1:00 - CAT 1979 Oct 14 + 1:00 1:00 CAST 1980 Mar 8 + 1:00 - CAT + +# Comoros +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Indian/Comoro 2:53:04 - LMT 1911 Jul # Moroni, Gran Comoro + 3:00 - EAT + +# Congo +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Brazzaville 1:01:08 - LMT 1912 + 1:00 - CAT + +# Cote D'Ivoire +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Abidjan -0:16:08 - LMT 1912 + 0:00 - WAT + +# Djibouti +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Djibouti 2:52:36 - LMT 1911 Jul + 3:00 - EAT + +############################################################################### + +# Egypt + +# From Bob Devine (January 28, 1988): +# Egypt: DST from first day of May to first of October (ending may +# also be on Sept 30th not 31st -- you might want to ask one of the +# soc.* groups, you might hit someone who could ask an embassy). +# DST since 1960 except for 1981-82. + +# From U.

Basil Hall, RN (1788-1844), +# famed explorer and former Commissioner for Longitude. +# The first railway to adopt London time was the Great Western Railway +# in November 1840; other railways followed suit, and by 1847 most +# (though not all) railways used London time. On 1847 Sep 22 the +# Railway Clearing House, an industry standards body, recommended that GMT be +# adopted at all stations; the January 1848 Bradshaw's lists most major +# railways as using GMT. By 1855 the vast majority of public +# clocks in Britain were set to GMT (though some, like the Great Clock +# in Tom Tower at Christ Church, Oxford, were fitted with two minute hands, +# one for local time and one for GMT). The last major holdout was the legal +# system, which stubbornly stuck to local time for many years, leading +# to oddities like polls opening at 08:13 and closing at 16:13. +# The legal system finally switched to GMT when the Statutes (Definition +# of Time) Act took effect; it received the Royal Assent on 1880 Aug 2. +# +# In the tables below, we condense this complicated story into a single +# transition date for London, namely 1847 Sep 22.

According to the +# Summer Time Order 1992 (SI 1992/1729) the dates of Summer Time for 1993 +# and 1994 are: +# Start End +# 1993 28 March 24 October +# 1994 27 March 23 October +# All start and end times are at 01:00 GMT. +# +# There [was] an error in your tables for the start and end times prior to 1981. +# The UK always used to change at 02:00 GMT. In 1981 it changed to 01:00 GMT +# as a part of EC harmonisation and has remained at that time since. +# +# I have found the default algorithm for UK Summer Time, it is in the +# Summer Time Act 1972. Section 1 states that in the absence of an Order +# in Council Summer Time starts at 02:00 GMT on the morning of the day +# after the third Saturday in March, unless that day is Easter Day, in +# which case it is the morning of the day after the second Saturday. +# It ends at 02:00 GMT on the morning of the day after the fourth Saturday +# in October. (All the redundant `morning of the day ...' is in the Act.) +# This is only of passing interest now as it will always be overridden by +# an Order in Council (a Statutary Instrument, the SI thing mentioned above) +# to specify the EC specified dates. + +# From Peter Ilieve <peter@memex.co.uk> (October 18, 1993): +# +# My contact in the Ministry of Defence Public Relations department +# accepted the challenge of looking into this and produced the following, +# from Hansard (the official record of the UK Parliament), Oral Answers, +# 1 March 1945, cols 1559--60: +# +# `58.

The little bit of it that is repealed +# also refers solely to Ireland and Dublin Mean Time. + +# From Peter Ilieve <peter@memex.co.uk> (October 29, 1993): +# +# My case is that, with the sole exception of Ireland in 1916 using Dublin +# Mean Time, Summer Time has been uniform throughout the United Kingdom +# ever since it first started in 1916. +# +# The United Kingdom is England, Wales and Scotland plus all of Ireland from +# 1916 up to and including 1921, or plus Northern Ireland from 1922 to date. +# +# The dates used are those specified in the table in Summer Time: A Consultation +# Document (Cm 722, 1989) that are now included in the europe file, with a +# change to a single date, the start in 1924. I made a typo in my 1989 mail +# and the table itself is also wrong. The correct date is 13 April. +# The times were 02:00 GMT up to and including 1980, 01:00 GMT from 1981 on, +# except for wartime double summer time. +# +# As evidence I would cite: +# +# - The Summer Time Act, 1916. +# +# This specifically states that it applies to Ireland, specifies dates of +# 21 May and 1 October and times of 02:00, and says that in Ireland the +# times relate to Dublin mean time. It specifies an offset of 1 hour. +# +# - The Time (Ireland) Act, 1916 +# +# This abolishes Dublin mean time on 02:00 DMT 1 October 1916. +# It repeals that section of the Statutes (Definition of Time) Act, 1880 +# that specifies DMT. It is therefore a safe bet that DMT existed at least +# from 1880 and was the only alternative standard time in the UK. +# +# - The Summer Time Act, 1922 +# +# This specifies an offset of 1 hour and dates of the day after the third +# Saturday in April, unless that be Easter, in which case it is the day after +# the second Saturday, and the day after the third Saturday in September. +# The time is 02:00 GMT. It applied in 1922 and 1923, and longer if Parliament +# so approved. +# +# It specifically states that it applies to Northern Ireland, the Channel +# Islands, and the Isle of Man. +# +# - The Summer Time Act, 1925 +# +# This makes the 1922 Act permanent, with a change to the end date to the +# day after the first Saturday in October. It says nothing about extent, +# so that part of the 1922 Act will still apply. +# +# - The Defence (Summer Time) Regulations, 1939, SR&O 1939 No. 1379 +# [SR&O == Statutary Regulation and Order] +# +# These were made under the Emergency Powers (Defence) Act, 1939. +# It changes the end date to be the day after the third Saturday in November. +# It makes consequential changes to some vehicle lighting legislation, +# which includes the Motor Vehicles and Road Traffic (Northern Ireland) Act, +# 1934, so it seems clear it applies in Northern Ireland. +# +# - An Order in Council amending the The Defence (Summer Time) Regulations, +# 1939, SR&O 1940 No. 1883 +# +# This continues summer time throughout the year after it starts in 1940. +# It says nothing about extent and has no consequential changes. +# +# - An Order in Council amending the The Defence (Summer Time) Regulations, +# 1939, SR&O 1941 No. 476 +# +# This introduces double summer time, starting at 01:00 GMT on the day after +# the first Saturday in May and ending at 01:00 GMT on the day after the +# second Saturday in August, offset another hour from normal summer time, +# which continues throughout the rest of the year. It goes on a lot about +# consequential changes to agricultural wages legislation, and says in part +# `... and in its application to Northern Ireland have effect as +# if for the references to the Agricultural Wages (Regulation) Acts, 1924 and +# 1940, there were substituted references to the Agricultural Wages (Regulation) +# Acts (Northern Ireland), 1939 and 1940, ...'.

It also said it +# applied to Jersey, Guernsey and the Isle of Man unless they passed +# measures saying it didn't. +# +# - The Manx Time Act, 1968 +# +# This is an Act of Tynwald (the Isle of Man Parliament) that said that +# henceforth Manx time would be the same as the time in Great Britain. +# +# - The Summer Time Act, 1972 +# +# This specified a reversion to normal summer time behaviour with a start +# date of the day after the third Saturday in March, unless that is Easter, +# when it is the day after the second Saturday, and an end date of the day +# after the fourth Saturday in October. Times are at 02:00 GMT, offset is +# 1 hour. +# +# It has the same wording about extent as the British Standard Time Act, 1968, +# applying to Northern Ireland unconditionally and to Jersey, Guernsey and the +# Isle of Man if they don't do something about it. +# +# (I am missing various Summer Time Orders that modified the 1972 Act to +# harmonise with the EC since 1981. The major change is that the time changes +# to 01:00 GMT.) +# +# - The Summer Time Order, 1992, SI 1992/1729 [SI == Statutary Instrument] +# +# This specifies dates of: +# Start End +# 1993 28 March 24 October +# 1994 27 March 23 October +# All start and end times are at 01:00 GMT.... +# +# - Some text on the extent of Acts, from Halsbury's Statutes +# +# `An Act of the United Kingdom Parliament is to be construed prima facie +# to apply to the whole of the United Kingdom and not to any place outside. +# [...] The expression "United Kingdom" for this purpose includes (since +# 1922) Great Britain (ie.

Previously, local mean solar time was used in different parts +# of Iceland, the almanak had been based on Reykjavik mean solar time which +# was 1 hour and 28 minutes behind GMT. +# +# "first day of winter" referred to [below] means the first day of the 26 weeks +# of winter, according to the old icelandic calendar that dates back to the +# time the norsemen first settled Iceland. The first day of winter is always +# Saturday, but is not dependent on the Julian or Gregorian calendars. +# +# (December 10, 1993): +# I have a reference from the Oxford Icelandic-English dictionary for the +# beginning of winter, which ties it to the ecclesiastical calendar (and thus +# to the julian/gregorian calendar) over the period in question. +# the winter begins on the Saturday next before St. Luke's day +# (old style), or on St. Luke's day, if a Saturday. +# St. Luke's day ought to be traceable from ecclesiastical sources.

+This effectively implies that POSIX time_t's cannot include leap +seconds and, +therefore, +that the system time must be adjusted as each leap occurs. +.PP +If the time package is configured with leap-second support +enabled, +however, +no such adjustment is needed and +time_t values continue to increase over leap events +(as a true `seconds since...' value). +This means that these values will differ from those required by POSIX +by the net number of leap seconds inserted since the Epoch. +.PP +Typically this is not a problem as the type time_t is intended +to be +(mostly) +opaque\(emtime_t values should only be obtained-from and +passed-to functions such as +.IR time(2) , +.IR localtime(3) , +.IR mktime(3) , +and +.IR difftime(3) . +However, +POSIX gives an arithmetic +expression for directly computing a time_t value from a given date/time, +and the same relationship is assumed by some +(usually older) +applications. +Any programs creating/dissecting time_t's +using such a relationship will typically not handle intervals +over leap seconds correctly. +.PP +The +.I time2posix +and +.I posix2time +functions are provided to address this time_t mismatch by converting +between local time_t values and their POSIX equivalents. +This is done by accounting for the number of time-base changes that +would have taken place on a POSIX system as leap seconds were inserted +or deleted. +These converted values can then be used in lieu of correcting the older +applications, +or when communicating with POSIX-compliant systems. +.PP +.I Time2posix +is single-valued. +That is, +every local time_t +corresponds to a single POSIX time_t. +.I Posix2time +is less well-behaved: +for a positive leap second hit the result is not unique, +and for a negative leap second hit the corresponding +POSIX time_t doesn't exist so an adjacent value is returned. +Both of these are good indicators of the inferiority of the +POSIX representation. +.PP +The following table summarizes the
