6 -- Fixed a memory leak in syslogd (found by Adam Slattery).
7 * Vladimir Oleynik, Matt Kraai, Erik Andersen

14 * David McCullough <davidm@lineo.com> -- modprobe
15 * Vladimir Oleynik -- traceroute
16 * Erik Andersen -- pidof

26 -- various little things
27 -- fixed busybox.spec so it should now work on redhat systems
28 -- fixed dos2unix and unix2dos so they should work once again
29 -- Adjustments to make busybox more uClinux friendly. Busybox
30 should now work on uClinux systems without needing and source
31 code changes (applets that won't work on uClinux systems are
32 now automagicaly disabled).
33 * Jim Gleason <jimg@lineo.com>
34 -- Fixed for sed, where it failed to preserve whether or not the
35 line was previously altered when running a subst command.
37 -- Made tar read 20 512byte blocks at a time (like GNU tar)
38 -- Allow msh.c assignments with the export and readonly commands.

53 -- Adjustments to make busybox more uClinux friendly
55 -- Fixed gzip so when a filename is '-' it will use stdin/stdout
56 -- dpkg rewrite. Should now be compatable with the real dpkg,
57 but needs more testing.
58 -- Updates to archiving tools (gunzip/gzip/cpio/ar/etc)
59 -- Rewrote uuencode, will allow base64 encoding to be used by wget
61 -- Fixed tr to support 'tr a-z A-Z' syntax,
62 -- Many ash corrections, optimizations, and cleanups.
63 -- optimizations for traceroute, md5sum, chown, ping
64 -- cmdedit updates and API change
65 -- Namespace cleanup (i.e. adding 'static' private function calls)
66 -- added "stopped jobs" warning to ash on exit
68 -- Fixed ping compile problem

86 only supports unpacking the ascii cpio format.
87 * Vladimir Oleynik and Erik Andersen -- added ash, the most correct
89 * Larry Doolittle -- hush, small shell designed specifically
90 for busybox. Quite usable but still a work in progress.

215 * Magnus Damm -- added a tftp applet
216 * Magnus Damm -- powerpc support for busybox insmod.
217 * David Douthitt -- fixed a build error in df.c when

346 mis-detected (causing problems with poweroff, init,
348 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and

350 and StrongArm, and suport for lsmod on older 2.0.x kernels.
351 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use

353 also a shell script called undeb included for debian packages.
354 * Matt Kraai -- fix an infinite loop with ls -aR

374 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
375 binary search instead of linear search. Much faster!
376 * new applets: cmp readlink
377 * Mark Whitley -- Removed advertising clause of Berkeley license
378 according to decision by the Regents of the University of
379 California; included reference

394 -Erik Andersen, 13 December 2000
398 * A bug in syslogd was fixed that allowed it to potentially fork-bomb

410 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
411 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
412 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
413 * 'xargs' (written by me)
414 * 'expr' contributed by Edward Betts <edward@debian.org>, based
416 * lsmod now uses the query_module syscall, rather then /proc (me)
417 * syslogd can now log messages to remote hosts -- patch thanks
418 to Gyepi Sam <gyepi@praxis-sw.com>
419 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
420 * 'make install' now creates relative symlinks, and added a new
421 'make install-hardlinks' target to (tada) install hardlinks.
422 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
423 It now weighs only 2.25k (3k when full featured). The code is

425 * Add optional ls file sorting, thanks to a patch from
426 Sterling Huxley <sterling@europa.com>
427 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'

431 * Preliminary support for GNU HURD.
432 * Updated my devps and devmtab kernel patches for the latest 2.2.x
433 kernel, for those wanting to go proc-less.
434 * Tons of other bugfixes.
437 -Erik Andersen, 25 September 2000
442 * Better portability. Now should compile cleanly with libc5,
443 GNU libc 2.0 and 2.1, and various Linux kernels including
444 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
445 to make /proc/mounts behave included in the kernel-patches dir).
446 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
447 local files that matched tarball contents!!! Fix thanks
448 to Marius Groeger <mgroeger@sysgo.de>
449 * Fixed a nasty bug in tar when could mess up saved symlinks.
450 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
451 thanks to Daniel Quinlan <quinlan@transmeta.com>
452 * Updates to handle Linux 2.4.0 kernels (kludged around the
453 "none" entries in /proc/mounts, added a hack to make sysinfo
454 work with both old and new kernels).
455 * Fixed insmod module option parsing for options lacking an '='.
456 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
457 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
458 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
459 * Several fixes from Marius Groeger <mag@sysgo.de>
460 - Added support for "sh -c command args..."
461 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
462 - Added shell environment variable substitution
463 - Added the "read" shell builtin.
464 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
465 used to create an infinite loop: ls, cursor up, left, down.
466 * Added support for being a login shell, so things like
467 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
468 invoke the shell. Now you can use BusyBox as a login shell.
469 * ls.c now ignores '-g', since some ftp clients like that sort
470 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
471 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
472 it always sets the controlling terminal before running any programs
473 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
474 - Fixed tr so it recognizes standard escape sequences.
475 Merged common escape seq. code from tr and echo into utility.c.
476 - Major work in updating/cleaning up the docs, and getting the
477 new SGML based docs into shape.
479 - BusyBox should now poweroff when asked to do so.
480 - Fixed 'ln -n' and 'ln -s' so they both work properly.
481 * Reorganized signal names in kill.c for better architecture support
482 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
483 * In 0.43, backspace and delete worked properly, but with 0.45,
484 it just echoed a ^? for backspace, and ^H for control-h. This
485 was due to a broken macro in init.c, that is now fixed.
486 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
487 couldn't maintain it very well, so including it was not really
488 very appropriate. Those wanting an fdisk are invited to
489 grab a copy from util-linux.
490 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
491 then be loaded in by 'loadkmap' -- submitted by
492 Arne Bernin <arne@matrix.loopback.org>
493 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
494 * Brand, new versions of grep and sed which use libc regex routines,
495 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
496 "regexp.[ch]" files have been removed. Much help on these from
500 -Erik Andersen, 11 July 2000
504 * Now compiles vs libc5 (which can save lots of space for
506 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
507 help messages (i.e --help). Saves 17k over a full compile.
508 * Added cut and tr from minix, since due to the license change,
509 we can now use minix code. Minix tr saves 4k.
510 * insmod now works. It costs 29k, but imagine an initrd with a
511 staticly linked busybox containing only insmod and sh, a few /dev
512 entries, and a kernel module or two... It doesn't get smaller
513 then this folks (I pity the fool that writes insmod in asm ;-).
514 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
515 * Added a mini ar archive utility, especially written for BusyBox by
516 Glenn McGrath <bug1@netconnect.com.au>
517 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
518 * Added setkeycodes, for those that have wierd keyboard buttons.
519 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
520 <ams@trillian.itslinux.org> for contributing these.
521 * Added 'grep -v' option (inverted search) and updated
522 docs accordingly. -beppu
524 * Replaced the telnet implementation with one written by
525 Tomi Ollila <too@iki.fi> It works great and costs 3k.
526 * BusyBox sh (lash) now supports being used as a standalone shell. When
527 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
528 be invoked as shell internals. Best used when compiling staticly
530 * BusyBox sh (lash) internals now behave as expected wrt pipes
532 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
533 * Fixed update segfault
534 * Fixed mknod -- minor number was always 0
535 * Fixed tar option parsing, so both "tar xvf foo.tar" and
536 "tar -xvf foo.tar" now work (i.e. no "-" before options)
537 (this was very broken in 0.43).
538 * Several contributions from Randolph Chung <tausq@debian.org>.
539 * cp/mv now accepts the -f flag
540 * tail can now accept -<num> commands (e.g. -10) for better
541 compatibility with the standard tail command
542 * added a simple id implementation; doesn't support sup. groups yet
543 * logname used getlogin(3) which uses utmp. Now it doesn't.
544 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
545 * Add support for "noatime" and "nodiratime" mount flags to mount.
546 * Changed 'umount -f' to mean force, and actually use umount2.
547 * Changed 'umount -l' to mean "Do not free loop device".
548 * Fixed basename to support stripping of suffixes. Patch thanks
549 to xiong jianxin <jxiong@uiuc.edu>
550 * cp -fa now works as expected for symlinks (it didn't before)
551 * zcat now works (wasn't working since option parsing was broken)
552 * Renamed "mnc" to the more correct "nc" (for netcat).
553 * Makefile intelligence updates
554 * Changed the way init parses /etc/inittab entries to avoid problems
555 with commands that contain colons in them. Fix thanks to
556 Pavel Roskin <proski@gnu.org>
557 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
558 Fix thanks to Pavel Roskin <proski@gnu.org>
559 * Made "killall" complain (not error and exit) about processes that it
560 cannot find by name -- Pavel Roskin <proski@gnu.org>
561 * Fixed more and ps to have sensible terminal width defaults, thanks
563 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
564 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
565 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
566 * Fixed segfault caused by "touch -c"
567 * Fixed segfault caused by "rm -f"
568 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
569 and "--" support from Pavel Roskin.
570 * Fixed segfault caused by "cp -a -a" and similar abuses.
571 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
572 * "which" rewritten to use stat(). Fixes to improve its compatability
573 with traditional implementations -- Pavel Roskin.
574 * "mount" now reports errors from nfsmount() and assumes NFS mount
575 if ':' is present in the device name - Pavel Roskin
576 * Fixed exit status for killall - Pavel Roskin
577 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
578 * Fixed 'mount -a' so it works as expected.
579 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
580 * Implemented "ping -s", fixed error messages and argument parsing -
582 * Syslogd will not go to background if "-n" is given. Better help
583 and argument checking -- Pavel Roskin
584 * Fixed a small bug that could cause tar to emit warning messages
585 and not extract the first file in a directory in some cases
586 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
587 for helping track this one down.
589 * Fixed grep "Line too long" problem -- John Beppu
590 * Fixed 'grep -q -i B some_file' so it works
591 * math takes input from stdin if no args are given. -- John Beppu
592 * math was renamed to dc. Although it deviates from dc's behaviour,
593 this will probably be remedied in the future. -- John Beppu
596 -Erik Andersen, June 21, 2000
600 Previously, an erronous announcement of BusyBox 0.44 was made, so to
601 avoid possible confusion, we are skipping straight to 0.45, and calling
608 * Major update to the provided documentation.
609 * Busybox now includes a shell! It currently costs 7.5 k (plus an
610 additional 2.5 k if you compile in command line editing). Handles
611 job control, has the usual set of builtins, and does everything
612 except for handling programming statements (if, while, etc...)
613 * Busybox can now work perfectly when /proc is disabled, thereby
614 saving a bunch of memory (kernel /proc support is not thin). This
615 is done by making use of some nice kernel patches I wrote up to
616 support the features that busybox requires and that /proc usually
617 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
618 patch your kernel with the devps patch in the kernel-patches/
620 * Wrote basename, dirname, killall, and uptime.
621 * tar has been completely rewritten by me. Both tar creation and
622 extraction are now well behaved. Costs 7.6k with all optional
623 tar features enabled, and 5k for just tar extraction support.
624 * Added freeramdisk, which will free up all memory associated
625 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
626 and then adjusted a bit by me.
627 * Added tr from John Lombardo <john@deltanet.com>
628 * Added echo and test (from me).
629 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
630 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
631 * Several fixes from Pavel Roskin <proski@gnu.org>:
632 - When `tail' fails to open a file it now exits.
633 - When `syslogd' is given the `-n' option it should still use
634 fork() for running klogd.
635 * nslookup types are now changed to u_int32_t (instead of uint32_t)
636 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
637 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
638 to count hard-linked files more then once). Many thanks to
639 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
640 * Removed /proc dependancies for init and free (while maintaining
641 exactly the same functionality). /proc takes up 90k of kernel
642 space, so it is nice to avoid using it at all costs.
643 * init no longer tries to mount /proc (unless there is less the 1 meg
644 free). Use of /proc (or not) is policy that should be set up in
645 /etc/fstab (or in hardcoded scripts), not in init.
646 * Fixed rebooting when init runs as an initrd.
647 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
648 - update.c rewritten to look more like update-2.11
649 - moveed the inode hash out of du.c and into utility.c to make
650 it a common resource that can be used by other apps.
651 - cp_mv.c now checks inodes to see if a source and dest are
652 the same, and prints an error (instead of endlessly looping).
653 - mv now attempts to do a rename, and will fall back to doing
654 a copy only if the rename fails.
655 - Syslogd now supports multiple concurrent connections
656 * Several fixes from Pavel Roskin <proski@gnu.org>:
657 - Fixes to sort. Removed "-g", fixed and added "-r"
658 - Fixes to the makefile for handling "strip"
659 * An initial telnet implementation was added by
660 Randolph Chung <tausq@debian.org>.
661 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
662 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
663 to match the terminal (defaults to width=79 when this is off).
664 * ps now accepts (and ignores) all options except for "--help" (which
665 as would be expected displays help).
666 * Fixed mount'ing loop devices when the filesystem type was not
667 specified. It used to revert to non-loop after the first try.
668 * all mallocs now use xmalloc (and so are OOM error safe), and
669 the common error handling saves a few bytes. Thanks to
670 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
671 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
672 * Fix symlink following bug in chmod -R and friends.
673 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
674 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
683 * Fairly massive restructuring of umount.c to deal with remounting
684 busy devices read-only. Adds a -r option to control that; it is
685 optionally compiled in with BB_FEATURE_REMOUNT
686 * Added a bunch of functions to mtab.c to interact with the
687 {get,set,end}mntent interface; as it turns out, those functions do
688 not appear to be re-entrant, and that causes a lot of problems with
689 the way umount was originally written.
690 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
691 to be more consistent with sysvinit
692 * Changes to init.c to use the new -r option to umount. Also increased
693 the sleep time between the time the TERM and KILL signals are sent
698 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
699 extensively rewritten from the original cp.c.
700 * Fixed cp and mv so if the source and destination are a the
701 same directory it will print an error and continue.
702 * Also added a warning message to the `mv' usage string saying that
703 this is not GNU mv, and it will break hard links. cp also breaks
705 * ln.c: implemented `-n' switch, no-deref symlinks.
706 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
707 * name buffer overrun guards to prevent future crashes.
708 - Always check exit status.
709 - Purge all use of `creat()', replace with `open()'.
711 - recursiveAction was overriding the value of followLinks thus
713 - isDirectory now takes a followLinks boolean, updated all callers
714 - copyFile had the followLinks logic reversed.
715 * messages.c: New file. Put common error message strings all in
716 one place in an attempt to shrink the binary a little.
721 * changed fsck_minix.c to reduce its .bss size significantly
723 * Made tar creation support in busybox tar optional. You no longer
724 * _have_ to put a "-" in front of tar options. Tar could inadvertently
725 * change permissions and ownership on
726 certain directories pointed to by symlinks.
727 * Made grep and grep -h do the right thing wrt printing
728 the file name (it failed to print files names in many cases).
729 * Fix a namespace aliasing problem wereby if du was built in, the
730 symlink for both du and dutmp would be installed, or then rm was
731 built in, the symlinks for both rm and rmmod would be installed.
732 * Added a closelog() to init.c after loging -- fix thanks to
733 Taketoshi Sano <kgh12351@nifty.ne.jp>
734 * Rewrote and simplified logger. Added the "-t" option, and made it
735 behave itself a bit better.
736 * Optional support contributed by Ben Collins <bcollins@debian.org>
737 for the kernel init chroot patch by Werner Almesberger, which
738 allows init to chroot to a new device, and umount the old one.
739 * Fixed bug that wouldn't let one chown a symlink -- it would
740 always dereference before. -beppu
741 * Fixed a bug where init could have reference already freed memory.
742 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
743 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
744 * Added (and documented) "-n" option for head
745 * Cleanup for a number of usage messages -- also
746 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
747 * Cosmetic fix to busybox.c (Don't print a comma at the
748 end of line if there are no more application names).
749 * Fixed a stupid bug in "head" option handling ("head -n"
751 * Moved commonly used functions "xmalloc()" and "exit()"
752 to utility.c (with proper #ifdef's).
753 * Created a tiny tail implementation, removing -c, -q, -v, and making
754 tail -f work only with a single file. This reduced tail from 6k to
755 2.4k. The bigger/more featured tail can still be had by disabling
756 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
757 * Ping now falls back to doing the right thing if /etc/protocols
759 * Fixed mount and umount. Previously they could leak loop device
760 allocations, causing the system to quickly run out. Fix for umount
761 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
762 * ls formatting on eight charactor user names fixed by
763 Randolph Chung <tausq@debian.org>.
764 * cp could, when copying symlinks, change permissions of the
765 files pointed to by the symlinks.
766 * Several fixes from Pavel Roskin <proski@gnu.org>:
767 - `chown' with 1 argument displayed the error incorrectly
768 - `fdflush', `length' and `printf' crashed if run without arguments
769 - `fdflush' tried to flush itself using *argv
770 - added "skip" and "seek" to dd.
771 - ls no longer messus up output when combining files and
772 directories on the command line
773 * swapoff -a was not working. Now it is.
774 * init did not cleanly unmount filesystems on reboot. Now it does.
775 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
777 * Some architectures (PowerPc) assume chars are unsigned, so they could
778 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
779 * Began converting error handling to use some common routines
781 * syslogd now has better message handling and ignores SIGHUP.
782 * install.sh had a bug preventing installation to the specified
783 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
784 * You can now spefify alternative strip commands -- change
785 also from Gilbert Coville.
791 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
792 by Edward Betts <edward@debian.org>
793 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
794 type commands (file in a directory to another directory) from
796 * Fixed a logger bug that caused garbage to be written to the syslog
797 (unless you used busybox syslog, which hid the bug). Thanks to
798 Alex Holden <alex@linuxhacker.org> for the fix.
799 * /bin/true and /bin/false were echoing a blank line when run.
801 * mkdir -p would print an error when asked to mkdir an existing dir
802 with no interveining subdirectories.
803 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
804 * and support in umount for loop
805 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
806 <bcollins@debian.org>
807 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
808 * fullWrite() not only if BB_TAR is defined, but also
809 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
810 * add some compiler optimizations to further reduce executable size
811 (as a side note, on my machines the largest code is generated
812 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
814 * Compile now won't fail if busybox.def.h defines
815 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
816 referenced, but not compiled)
817 * Fixed a bug in setting TERM for serial console support. TERM now
818 defaults to "ansi" for serial consoles.
819 * Fixed a bug in handling the CONSOLE env. variable for serial
822 -Erik Andersen, Jan 15, 2000
825 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
826 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
827 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
828 for loading application character maps for Unicode fonts.
829 * Major init re-work. init now supports inittab (slightly different
830 but similar to sysvinit), allowing me to get all the policy out of
831 init and into the conf file. It works just fine without inittab
832 being present, but if you dont like the default behavior you can
833 now do something about it. Init is much cleaner as a result.
834 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
835 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
836 * failure of 'logger -p'. -erik Added the -s option to du -beppu
837 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
838 with the 2.0.x Linux kernel.
839 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
841 * Grep -i previously failed on UPPER CASE patterns due to a silly
842 regexp implementation bug that is now fixed.
843 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
844 * Fixed a bug where tar would not set the user and group on device
846 * Fixed a bug where tar would not restore the time to files. Fixed a
847 * major security problem with tar -- it changed ownership
848 of any file pointed to by a symlink to 777 (like say libc....)
850 * cp and mv were very broken when moving directories. I have rewritten
851 them so they should now work as expected.
852 * sed now supports addresses (numeric or regexp, with negation) and
853 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
854 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
855 * Some cosmetic fixes to ls output formatting to make it behave more
857 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
858 * <fwv@myrtle.lahn.de>:
859 - Added gunzip -t, removed gunzip.c dead code,
860 - fixed several typos
861 - Glibc 2.0.7 and libc5 compile fixes
862 * Fixed a bug where 'mknod --help' would segfault.
865 -Erik Andersen, Jan 07, 2000
868 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
869 <tausq@debian.org>. 3 items off the TODO list!
870 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
871 * tail from GNU textutils-1.19, but adjusted
872 to suit my evil purposes. Costs 6k. I'll make it smaller
874 * on reboot, init called 'umount -a -n', which caused errors
875 when BB_MTAB was not enabled. Changed to 'umount -a', which does
877 * init will now try to run /sbin/getty if it is present (for easy
878 integration with the about-to-be-released tinylogin.)
879 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
880 * -l' was failing on long directories, since my_getid was leaking
881 one file descriptor per file. Oops.
882 * Fixed rebooting from init. I'd accidently left some debugging code
884 which blocked reboots.
885 * Fixed reboot, halt (and added poweroff) such that they handle it when
886 init is not at PID 1 (like when running in an initrd).
887 * Added a prelinary du implementation. Some parameter parsing
888 stuff still needs to be added. -beppu (John Beppu
890 * Implemented tee. -beppu Implemented head. -beppu
892 -Erik Andersen, Dec 10, 1999
895 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
897 * df will not exit on error, but will stat all mounted filesystems.
898 * Fixed tar so uid/gid/permissions on extracted tarballs will be
900 * Fixed find -name so it properly uses shell wildcard patterns
901 (i.e. `*', `?', and `[]') instead of regular expressions, which
902 was causing some confusing and unexpected behavior.
903 * Added klogd to syslogd, so now the log will contain both system and
905 * syslogd now creates the /dev/log socket to make sure it is there, and
906 is actually a socket with the right permissions.
907 * I've taken a first step to making busybox not need the /proc
908 filesystem. Most apps don't need it. Those that _require_ it,
909 will complain if you enable them when you disable
910 BB_FEATURE_USE_PROCFS.
912 -Erik Andersen, Dec 5, 1999
915 * Wrote a micro syslogd, and a logger util (to log things to the syslog
916 from the command line or scripts) With both compiled in, costs 4k.
917 * Fixed 'make install' so symlinks are installed in their proper
918 * locations. Changed the build system slightly so that features can
920 or disabled from the busybox.defs.h header file, without trying to
921 compile in a source file named after that featue (unless that file
923 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
924 * -r' both work. dd now properly handles input beyond 1 block from
925 * stdin. Fixed a bug where tar unpacked everything a directories.
927 from createPath into mkdir where it belonged, thereby making tar
929 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
931 last file in the list.
932 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
934 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
935 are presented properly.
939 -Erik Andersen, Nov 25, 1999
942 * fixed dd so it properly defaults to stdin and stdout when no
943 if= and of= are set (fix thanks to Eric Delaunay).
944 * Don't try to close the file descriptor of a pipein tar. (fix also
947 * Made createPath be quiet (again thanks to Eric Delaunay). If
948 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
949 command you define it as will be run if the init script exits.
950 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
951 * NFS support added to mount by Eric Delaunay. It costs 10k when
953 in, but that is still a big win for those that use NFS.
954 * Made 'rm -f' be silent for non-existant files (thanks to Eric
955 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
957 and acts as god intended gunzip and zcat to act. They answer
958 --help and obey the '-c' flag.
959 * Fixed a bug in mv which caused it to not move files when the
962 * Fixed a decimal-instead-of-octal bug causing mkdir to make
964 with very wrong permissions.
965 * chmod would overwrite file permissions instead of modifying them.
966 Now it properly modifies permissions.
967 * Init now sends warnings destined for the console to /dev/console to
969 they show up on whatever the active console it. Otherwise
970 important messages (for example that the system is rebooting) were
971 not seen when switched to a different VT.
973 -Erik Andersen, Nov 17, 1999
976 * gzip now obeys the principle of least surprise and acts like god
978 (i.e. it accepts a file name, answers --help, and obeys the '-c'
979 flag and only then outputs to stdout).
980 * Fixed more.c to compile autowidth on sparc and set initial winsize
981 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
983 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
984 * tar now accepts --help chmod, chown, and chgrp usage now works
985 * General usage (i.e. --help) cleanups for most apps umount now parses
986 * options correctly tar can now unpack tarballs containing device
988 sockets, and fifos (though it can't pack them up) thanks to Matt
989 Porter. Creating archives containing these is still left to the
991 * fixed up the license in more.c to properly point to Bruce Perens.
993 -Erik Andersen, Nov 11, 1999
996 * ls -l now displays link names outside the current directory,
997 Patch thanks to Eric Delaunay
998 * init now properly handles sparc serial consoles and does a
999 better job of finding the real console device rather than using
1000 /dev/console which doesn't support job control. Patch also thanks
1002 * more started to read from stdin after the last file was finished, and
1003 options were not parsed correctly (fix thanks to Eric Delaunay).
1004 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
1005 * rm wouldn't remove a symlink unless the symlink was valid. This was
1006 a side effect of the busybox 0.32 recursiveAction() fix. Things
1007 should now work correctly.
1008 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
1009 * it does. sed was appending a \n to the end of lines with
1011 Now it doesn't do that.
1012 * ls -l now bypasses libc6 nss when displaying user/group names.
1013 Now uses my_getpwuid and my_getgrgid.
1015 -Erik Andersen, Nov 8, 1999
1018 * Fixed a bug where init could hang instead of rebooting.
1019 * Removed some debugging noise from init.c
1020 * Fixed ln so it works now (it was very broken).
1021 * Fixed df so it won't segfault when there is no /etc/fstab,
1022 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
1023 is not installed (since they cannot fixup "/dev/root" to
1024 state the real root device name)
1025 * merged some redundant code from mtab.c/df.c into utility.c
1027 -Erik Andersen, Nov 5, 1999
1030 * More changes -- many thanks to Lineo for paying me to work on
1031 busybox. If you have any problems please let me know ASAP at
1032 andersen@lineo.com or andersee@debian.org
1033 * usage() now prints the BusyBox version. This will help folks
1034 realize that they are not in Kansas anymore.
1035 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
1036 * arguments. Now it doesn't do that. kill wasn't properly accepting
1037 * signal names. It does now. Added new apps chvt and deallocvt (I
1038 * should probably add open) Major rewrite of init.c. Code is now
1039 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
1040 * with full regular expressions!). Fixed a stupid seg-fault in sync
1041 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
1042 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
1043 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
1044 * cost of ~1.5k and the need for a rw /etc)
1045 folks to use a real /etc/mtab file instead of a symlink to
1046 /proc/mounts. mount, and umount will add/remove entries and df
1047 will now use /etc/mtab if BB_MTAB is defined.
1048 * Fixed a nice bug in recursiveAction() which caused it to infinitely
1049 hunt through /proc/../fd/* creating new file descriptors if it
1050 followed the /dev/fd link over to /proc. recursiveAction() now
1051 lstat's the file when followLinks==FALSE so it won't follow links
1052 as the name suggests. Fix thanks to Matt Porter
1053 <porter@debian.org>.
1056 -Erik Andersen, Nov 4, 1999
1059 * I added a changelog for version 0.30. adjusted find internals to
1060 * make it smaller, and removed
1062 * Fixed a segfault in ps when /etc/passwd or /etc/group
1063 are absent. Now will warn you and carry on.
1064 * Added in optional _real_ regular expression support (to be
1065 the basis for a future sed utility). When compiled in it adds
1066 3.9k, but makes grep much more capable.
1067 * Checked out using nftw(3) for recursive stuff, but unfortunatly
1068 it wasn't supported before GNU libc 2.1, and some folks use glibc
1069 2.0.7 since it is much smaller than that latest and greatest.
1071 -Erik Andersen, Oct 21, 1999
1074 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
1075 paying me to make these updates. If you have any problems with busybox,
1076 or notice any bugs -- please let me know so I can fix it. These
1080 * busybox can now invoke apps in two ways: via symlinks to the
1081 busybox binary, and as 'busybox [function] [arguments]...'
1082 * When invoked as busybox, the list of currently compiled in
1083 functions is printed out (no this is not bloat -- the list has
1084 to be there anyway to map invocation name to function).
1085 * busybox no longer parses command lines for apps or displays their
1086 usage info. Each app gets to handle (or not handle) this for
1088 * Eliminated monadic, dyadic, descend, block_device, and
1089 postprocess. It was cumbersome to have so many programs
1090 cobbled together in this way. Without them, the app is much
1092 * All shared code now lives in utility.c, and is properly
1093 ifdef'ed to be only included for those apps requiring it.
1094 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
1095 so now each app has the function prototype of (da-dum): extern
1096 int foo_main(int argc, char** argv); which speeds integration
1098 * Adjusted the Makefile to make it easier to
1099 {en|dis}able debugging.
1100 * Changed default compiler optimization to -Os
1101 (optimize for smaller binaries).
1104 * To cope with the new app function prototype and the removal of
1105 monadic, dyadic, etc, the following apps were re-written:
1106 * cat - Works same as always. chgrp, chmod, chown -
1107 * rewrite. Combined into a single
1108 source file. Absorbed patches from Enrique Zanardi
1109 <ezanard@debian.org> that removes the dependency on
1110 libc6 libnss* libraries.
1111 * cp - Can now do 'cp -a' can can copy devices,
1112 pipes, symlinks, as well as recursive or non-recursive
1114 * fdflush - adjusted to remove dependancy on struct
1115 * FileInfo. find - Now includes some basic regexp matching
1116 which will be the basic of a future mini-sed.
1117 * ln - Same functionality. mkdir - Added -p flag to
1118 * feature set. mv - rewrite. rm - Added -f flag to
1119 * feature set. rmdir - Same functionality. swapon,
1120 * swapoff - Combined into a single binary. No longer
1121 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
1123 * touch - Same functionality. date - adjusted with a patch
1124 * from Matthew Grant <grantma@anathoth.gen.nz>
1125 to accomodate glibc timezone support. I then ripped out GNU
1127 * mkswap -- new version merged from util-linux. Can now make
1129 * Replaced the old and star, unstar, and tarcat with the tar
1130 implementation from sash. Now tar behaves as god intended it
1131 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
1132 * dd -- rewritten. Can with with files, stdin, stdout. Added the
1133 * following new apps: loadfont -- added from debian boot floppies
1134 * chroot -- added based on a patch from Paolo Molaro
1135 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
1136 * simple strings ps -- I just wrote it. Has _no_ options at all,
1137 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
1139 internationalization and such to make them smaller.
1140 * sfdisk -- Added from util-linux (minus
1141 * internationalization and such). Probably some other
1142 * changes that I forgot to document...
1144 -Erik Andersen, Oct 20, 1999
1147 This version was a messy pre-alpha. stay away or it will bite you.
1148 -Erik Andersen, Sep 24, 1999
1151 mini-netcat (mnc) rewritten.
1154 Mount now supports -a, and -t auto.
1155 Mount now updates mtab correctly for 'ro'.
1156 More checks screen rows size, outputs bytes percentage.
1157 Printf added as module.
1159 Touch now creates files. -c option for no create.
