8 * Erik Andersen -- Merged several applets from tinylogin,
9 namely adduser, addgroup, deluser, delgroup, getty.

22 -Erik Andersen, --not yet released--
31 New Applets & New Features:
34 Known Problems (to be fixed in 0.60.2)
35 * msh can segfault on constructs such as
36 for i in `ls *.c` ; do echo $i ; done
37 due to a memory allocation problem. This only seems to cause
38 problems when the backtick expands to be several k in size.
43 -- Fixed msh to support underscores in variable names.
44 -- Fixed a sed problem with unsatisfied backrefs (the problem was
45 noted by Martin Bene).
46 -- Removed BB_SH define entirely. Now one simply picks the shell
47 or shells they want as BB_<foo> in Config.h
48 -- Fixed head to use ferror(3) to check for errors, not errno.
49 * Shu-Hao Chang <shuhao_chang@trend.com.tw>
50 -- Fixed sed handling of multiple -e commands
51 * Magick <magick@linux-fan.com>
52 -- Fixed an init bug with AskFirst and /dev/null
53 * Jaspreet Singh <jsingh@somanetworks.com>
54 -- Fixed both a segfault and cosmetic bug in route
56 -- Made the insmod options BB_FEATURE_NEW_MODULE_INTERFACE and
57 BB_FEATURE_OLD_MODULE_INTERFACE mutually exclusive
58 -- xgetcwd.c now includes sys/param.h to ensure PATH_MAX is defined
59 -- Fixed a potential segfault with lash + BB_FEATURE_CLEAN_UP
60 -- Removed uint64_t from dos2unix, avoiding C lib compat. problems.
62 -- Rewrite of tftp (commands match atftp, accepts -b, can use
63 non-standard ports, and is smaller).
64 -- Fixed unarchive exclude list handling
66 -- rewrite of simplify_path so it behaves itself (fixing some
67 problems with mount and other applets).
68 -- Fixed ifconfig 'broadcast +' handling and disabled it by default
69 * Matthias ? <matthias@corelatus.com>
70 -- Fixed syslogd to log all messages from a single connection, not
74 -Erik Andersen, 23 August 2001
81 For this release I have bumped the version number to 0.60.0. This
82 reflects the fact that this release is intended to form a new stable
83 BusyBox release series. If you need to rely on a stable version of
84 BusyBox, you should plan on using the stable 0.60.x series. If bugs
85 show up then I will release 0.60.1, then 0.60.2, etc... This is also
86 intended to deal with the fact that the BusyBox build system will be
87 getting a major overhaul for the next release and I don't want that to
88 break products that people are shipping. To avoid that, the new build
89 system will be released as part of a new BusyBox development series
90 that will have some not-yet-decided-on odd version number. Once things
91 stabablize and the new build system is working for everyone, then I
92 will release that as a new stable release series.
96 -- Fixed wget output file opening (wget failed in 0.52).
97 -- Fixed a memory leak in syslogd (found by Adam Slattery).
98 * Vladimir Oleynik, Matt Kraai, Erik Andersen

100 any variables and had debug code still enabled. ash
101 had several compile errors (depending on selected options)
102 and variable assignment problems as well.
105 * David McCullough <davidm@lineo.com> -- modprobe
106 * Vladimir Oleynik -- traceroute
107 * Erik Andersen -- pidof
110 * David Schleef, Erik Andersen, Stuart Hughes -- depmod.pl
111 This is a replacement for the depmod program from the modutils
112 package, but is fully cross platform and is designed to run on
113 your host system (not on the target).
117 -- fixed busybox.spec so it should now work on redhat systems
118 -- fixed dos2unix and unix2dos so they should work once again
119 -- Adjustments to make busybox more uClinux friendly. Busybox
120 should now work on uClinux systems without needing and source
121 code changes (applets that won't work on uClinux systems are
122 now automagicaly disabled).
123 -- various things (cleanups, libc compatibility work, etc, etc)

144 -- Adjustments to make busybox more uClinux friendly
146 -- Fixed gzip so when a filename is '-' it will use stdin/stdout
147 -- dpkg rewrite. Should now be compatable with the real dpkg,
148 but needs more testing.
149 -- Updates to archiving tools (gunzip/gzip/cpio/ar/etc)
150 -- Rewrote uuencode, will allow base64 encoding to be used by wget
152 -- Fixed tr to support 'tr a-z A-Z' syntax,
153 -- Many ash corrections, optimizations, and cleanups.
154 -- optimizations for traceroute, md5sum, chown, ping

185 that only uses vfork, so it can be used on uClinux systems.
188 * Sterling Huxley -- Several bugfixes for the vi applet.
189 * Glenn McGrath -- Restructure unarchiving code to make more code
190 common to the ar, cpio, dpkg, dpkg-deb applets.

530 -Erik Andersen, 25 September 2000
535 * Better portability. Now should compile cleanly with libc5,
536 GNU libc 2.0 and 2.1, and various Linux kernels including
537 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
538 to make /proc/mounts behave included in the kernel-patches dir).
539 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
540 local files that matched tarball contents!!! Fix thanks
541 to Marius Groeger <mgroeger@sysgo.de>
542 * Fixed a nasty bug in tar when could mess up saved symlinks.
543 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
544 thanks to Daniel Quinlan <quinlan@transmeta.com>
545 * Updates to handle Linux 2.4.0 kernels (kludged around the
546 "none" entries in /proc/mounts, added a hack to make sysinfo
547 work with both old and new kernels).
548 * Fixed insmod module option parsing for options lacking an '='.
549 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
550 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
551 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
552 * Several fixes from Marius Groeger <mag@sysgo.de>
553 - Added support for "sh -c command args..."
554 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
555 - Added shell environment variable substitution
556 - Added the "read" shell builtin.
557 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
558 used to create an infinite loop: ls, cursor up, left, down.
559 * Added support for being a login shell, so things like
560 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
561 invoke the shell. Now you can use BusyBox as a login shell.
562 * ls.c now ignores '-g', since some ftp clients like that sort
563 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
564 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
565 it always sets the controlling terminal before running any programs
566 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
567 - Fixed tr so it recognizes standard escape sequences.
568 Merged common escape seq. code from tr and echo into utility.c.
569 - Major work in updating/cleaning up the docs, and getting the
570 new SGML based docs into shape.
572 - BusyBox should now poweroff when asked to do so.
573 - Fixed 'ln -n' and 'ln -s' so they both work properly.
574 * Reorganized signal names in kill.c for better architecture support
575 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
576 * In 0.43, backspace and delete worked properly, but with 0.45,
577 it just echoed a ^? for backspace, and ^H for control-h. This
578 was due to a broken macro in init.c, that is now fixed.
579 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
580 couldn't maintain it very well, so including it was not really
581 very appropriate. Those wanting an fdisk are invited to
582 grab a copy from util-linux.
583 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
584 then be loaded in by 'loadkmap' -- submitted by
585 Arne Bernin <arne@matrix.loopback.org>
586 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
587 * Brand, new versions of grep and sed which use libc regex routines,
588 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
589 "regexp.[ch]" files have been removed. Much help on these from
593 -Erik Andersen, 11 July 2000
597 * Now compiles vs libc5 (which can save lots of space for
599 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
600 help messages (i.e --help). Saves 17k over a full compile.
601 * Added cut and tr from minix, since due to the license change,
602 we can now use minix code. Minix tr saves 4k.
603 * insmod now works. It costs 29k, but imagine an initrd with a
604 staticly linked busybox containing only insmod and sh, a few /dev
605 entries, and a kernel module or two... It doesn't get smaller
606 then this folks (I pity the fool that writes insmod in asm ;-).
607 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
608 * Added a mini ar archive utility, especially written for BusyBox by
609 Glenn McGrath <bug1@netconnect.com.au>
610 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
611 * Added setkeycodes, for those that have wierd keyboard buttons.
612 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
613 <ams@trillian.itslinux.org> for contributing these.
614 * Added 'grep -v' option (inverted search) and updated
615 docs accordingly. -beppu
617 * Replaced the telnet implementation with one written by
618 Tomi Ollila <too@iki.fi> It works great and costs 3k.
619 * BusyBox sh (lash) now supports being used as a standalone shell. When
620 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
621 be invoked as shell internals. Best used when compiling staticly
623 * BusyBox sh (lash) internals now behave as expected wrt pipes
625 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
626 * Fixed update segfault
627 * Fixed mknod -- minor number was always 0
628 * Fixed tar option parsing, so both "tar xvf foo.tar" and
629 "tar -xvf foo.tar" now work (i.e. no "-" before options)
630 (this was very broken in 0.43).
631 * Several contributions from Randolph Chung <tausq@debian.org>.
632 * cp/mv now accepts the -f flag
633 * tail can now accept -<num> commands (e.g. -10) for better
634 compatibility with the standard tail command
635 * added a simple id implementation; doesn't support sup. groups yet
636 * logname used getlogin(3) which uses utmp. Now it doesn't.
637 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
638 * Add support for "noatime" and "nodiratime" mount flags to mount.
639 * Changed 'umount -f' to mean force, and actually use umount2.
640 * Changed 'umount -l' to mean "Do not free loop device".
641 * Fixed basename to support stripping of suffixes. Patch thanks
642 to xiong jianxin <jxiong@uiuc.edu>
643 * cp -fa now works as expected for symlinks (it didn't before)
644 * zcat now works (wasn't working since option parsing was broken)
645 * Renamed "mnc" to the more correct "nc" (for netcat).
646 * Makefile intelligence updates
647 * Changed the way init parses /etc/inittab entries to avoid problems
648 with commands that contain colons in them. Fix thanks to
649 Pavel Roskin <proski@gnu.org>
650 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
651 Fix thanks to Pavel Roskin <proski@gnu.org>
652 * Made "killall" complain (not error and exit) about processes that it
653 cannot find by name -- Pavel Roskin <proski@gnu.org>
654 * Fixed more and ps to have sensible terminal width defaults, thanks
656 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
657 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
658 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
659 * Fixed segfault caused by "touch -c"
660 * Fixed segfault caused by "rm -f"
661 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
662 and "--" support from Pavel Roskin.
663 * Fixed segfault caused by "cp -a -a" and similar abuses.
664 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
665 * "which" rewritten to use stat(). Fixes to improve its compatability
666 with traditional implementations -- Pavel Roskin.
667 * "mount" now reports errors from nfsmount() and assumes NFS mount
668 if ':' is present in the device name - Pavel Roskin
669 * Fixed exit status for killall - Pavel Roskin
670 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
671 * Fixed 'mount -a' so it works as expected.
672 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
673 * Implemented "ping -s", fixed error messages and argument parsing -
675 * Syslogd will not go to background if "-n" is given. Better help
676 and argument checking -- Pavel Roskin
677 * Fixed a small bug that could cause tar to emit warning messages
678 and not extract the first file in a directory in some cases
679 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
680 for helping track this one down.
682 * Fixed grep "Line too long" problem -- John Beppu
683 * Fixed 'grep -q -i B some_file' so it works
684 * math takes input from stdin if no args are given. -- John Beppu
685 * math was renamed to dc. Although it deviates from dc's behaviour,
686 this will probably be remedied in the future. -- John Beppu
689 -Erik Andersen, June 21, 2000
693 Previously, an erronous announcement of BusyBox 0.44 was made, so to
694 avoid possible confusion, we are skipping straight to 0.45, and calling
701 * Major update to the provided documentation.
702 * Busybox now includes a shell! It currently costs 7.5 k (plus an
703 additional 2.5 k if you compile in command line editing). Handles
704 job control, has the usual set of builtins, and does everything
705 except for handling programming statements (if, while, etc...)
706 * Busybox can now work perfectly when /proc is disabled, thereby
707 saving a bunch of memory (kernel /proc support is not thin). This
708 is done by making use of some nice kernel patches I wrote up to
709 support the features that busybox requires and that /proc usually
710 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
711 patch your kernel with the devps patch in the kernel-patches/
713 * Wrote basename, dirname, killall, and uptime.
714 * tar has been completely rewritten by me. Both tar creation and
715 extraction are now well behaved. Costs 7.6k with all optional
716 tar features enabled, and 5k for just tar extraction support.
717 * Added freeramdisk, which will free up all memory associated
718 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
719 and then adjusted a bit by me.
720 * Added tr from John Lombardo <john@deltanet.com>
721 * Added echo and test (from me).
722 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
723 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
724 * Several fixes from Pavel Roskin <proski@gnu.org>:
725 - When `tail' fails to open a file it now exits.
726 - When `syslogd' is given the `-n' option it should still use
727 fork() for running klogd.
728 * nslookup types are now changed to u_int32_t (instead of uint32_t)
729 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
730 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
731 to count hard-linked files more then once). Many thanks to
732 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
733 * Removed /proc dependancies for init and free (while maintaining
734 exactly the same functionality). /proc takes up 90k of kernel
735 space, so it is nice to avoid using it at all costs.
736 * init no longer tries to mount /proc (unless there is less the 1 meg
737 free). Use of /proc (or not) is policy that should be set up in
738 /etc/fstab (or in hardcoded scripts), not in init.
739 * Fixed rebooting when init runs as an initrd.
740 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
741 - update.c rewritten to look more like update-2.11
742 - moveed the inode hash out of du.c and into utility.c to make
743 it a common resource that can be used by other apps.
744 - cp_mv.c now checks inodes to see if a source and dest are
745 the same, and prints an error (instead of endlessly looping).
746 - mv now attempts to do a rename, and will fall back to doing
747 a copy only if the rename fails.
748 - Syslogd now supports multiple concurrent connections
749 * Several fixes from Pavel Roskin <proski@gnu.org>:
750 - Fixes to sort. Removed "-g", fixed and added "-r"
751 - Fixes to the makefile for handling "strip"
752 * An initial telnet implementation was added by
753 Randolph Chung <tausq@debian.org>.
754 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
755 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
756 to match the terminal (defaults to width=79 when this is off).
757 * ps now accepts (and ignores) all options except for "--help" (which
758 as would be expected displays help).
759 * Fixed mount'ing loop devices when the filesystem type was not
760 specified. It used to revert to non-loop after the first try.
761 * all mallocs now use xmalloc (and so are OOM error safe), and
762 the common error handling saves a few bytes. Thanks to
763 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
764 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
765 * Fix symlink following bug in chmod -R and friends.
766 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
767 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
776 * Fairly massive restructuring of umount.c to deal with remounting
777 busy devices read-only. Adds a -r option to control that; it is
778 optionally compiled in with BB_FEATURE_REMOUNT
779 * Added a bunch of functions to mtab.c to interact with the
780 {get,set,end}mntent interface; as it turns out, those functions do
781 not appear to be re-entrant, and that causes a lot of problems with
782 the way umount was originally written.
783 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
784 to be more consistent with sysvinit
785 * Changes to init.c to use the new -r option to umount. Also increased
786 the sleep time between the time the TERM and KILL signals are sent
791 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
792 extensively rewritten from the original cp.c.
793 * Fixed cp and mv so if the source and destination are a the
794 same directory it will print an error and continue.
795 * Also added a warning message to the `mv' usage string saying that
796 this is not GNU mv, and it will break hard links. cp also breaks
798 * ln.c: implemented `-n' switch, no-deref symlinks.
799 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
800 * name buffer overrun guards to prevent future crashes.
801 - Always check exit status.
802 - Purge all use of `creat()', replace with `open()'.
804 - recursiveAction was overriding the value of followLinks thus
806 - isDirectory now takes a followLinks boolean, updated all callers
807 - copyFile had the followLinks logic reversed.
808 * messages.c: New file. Put common error message strings all in
809 one place in an attempt to shrink the binary a little.
814 * changed fsck_minix.c to reduce its .bss size significantly
816 * Made tar creation support in busybox tar optional. You no longer
817 * _have_ to put a "-" in front of tar options. Tar could inadvertently
818 * change permissions and ownership on
819 certain directories pointed to by symlinks.
820 * Made grep and grep -h do the right thing wrt printing
821 the file name (it failed to print files names in many cases).
822 * Fix a namespace aliasing problem wereby if du was built in, the
823 symlink for both du and dutmp would be installed, or then rm was
824 built in, the symlinks for both rm and rmmod would be installed.
825 * Added a closelog() to init.c after loging -- fix thanks to
826 Taketoshi Sano <kgh12351@nifty.ne.jp>
827 * Rewrote and simplified logger. Added the "-t" option, and made it
828 behave itself a bit better.
829 * Optional support contributed by Ben Collins <bcollins@debian.org>
830 for the kernel init chroot patch by Werner Almesberger, which
831 allows init to chroot to a new device, and umount the old one.
832 * Fixed bug that wouldn't let one chown a symlink -- it would
833 always dereference before. -beppu
834 * Fixed a bug where init could have reference already freed memory.
835 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
836 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
837 * Added (and documented) "-n" option for head
838 * Cleanup for a number of usage messages -- also
839 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
840 * Cosmetic fix to busybox.c (Don't print a comma at the
841 end of line if there are no more application names).
842 * Fixed a stupid bug in "head" option handling ("head -n"
844 * Moved commonly used functions "xmalloc()" and "exit()"
845 to utility.c (with proper #ifdef's).
846 * Created a tiny tail implementation, removing -c, -q, -v, and making
847 tail -f work only with a single file. This reduced tail from 6k to
848 2.4k. The bigger/more featured tail can still be had by disabling
849 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
850 * Ping now falls back to doing the right thing if /etc/protocols
852 * Fixed mount and umount. Previously they could leak loop device
853 allocations, causing the system to quickly run out. Fix for umount
854 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
855 * ls formatting on eight charactor user names fixed by
856 Randolph Chung <tausq@debian.org>.
857 * cp could, when copying symlinks, change permissions of the
858 files pointed to by the symlinks.
859 * Several fixes from Pavel Roskin <proski@gnu.org>:
860 - `chown' with 1 argument displayed the error incorrectly
861 - `fdflush', `length' and `printf' crashed if run without arguments
862 - `fdflush' tried to flush itself using *argv
863 - added "skip" and "seek" to dd.
864 - ls no longer messus up output when combining files and
865 directories on the command line
866 * swapoff -a was not working. Now it is.
867 * init did not cleanly unmount filesystems on reboot. Now it does.
868 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
870 * Some architectures (PowerPc) assume chars are unsigned, so they could
871 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
872 * Began converting error handling to use some common routines
874 * syslogd now has better message handling and ignores SIGHUP.
875 * install.sh had a bug preventing installation to the specified
876 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
877 * You can now spefify alternative strip commands -- change
878 also from Gilbert Coville.
884 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
885 by Edward Betts <edward@debian.org>
886 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
887 type commands (file in a directory to another directory) from
889 * Fixed a logger bug that caused garbage to be written to the syslog
890 (unless you used busybox syslog, which hid the bug). Thanks to
891 Alex Holden <alex@linuxhacker.org> for the fix.
892 * /bin/true and /bin/false were echoing a blank line when run.
894 * mkdir -p would print an error when asked to mkdir an existing dir
895 with no interveining subdirectories.
896 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
897 * and support in umount for loop
898 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
899 <bcollins@debian.org>
900 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
901 * fullWrite() not only if BB_TAR is defined, but also
902 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
903 * add some compiler optimizations to further reduce executable size
904 (as a side note, on my machines the largest code is generated
905 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
907 * Compile now won't fail if busybox.def.h defines
908 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
909 referenced, but not compiled)
910 * Fixed a bug in setting TERM for serial console support. TERM now
911 defaults to "ansi" for serial consoles.
912 * Fixed a bug in handling the CONSOLE env. variable for serial
915 -Erik Andersen, Jan 15, 2000
918 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
919 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
920 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
921 for loading application character maps for Unicode fonts.
922 * Major init re-work. init now supports inittab (slightly different
923 but similar to sysvinit), allowing me to get all the policy out of
924 init and into the conf file. It works just fine without inittab
925 being present, but if you dont like the default behavior you can
926 now do something about it. Init is much cleaner as a result.
927 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
928 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
929 * failure of 'logger -p'. -erik Added the -s option to du -beppu
930 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
931 with the 2.0.x Linux kernel.
932 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
934 * Grep -i previously failed on UPPER CASE patterns due to a silly
935 regexp implementation bug that is now fixed.
936 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
937 * Fixed a bug where tar would not set the user and group on device
939 * Fixed a bug where tar would not restore the time to files. Fixed a
940 * major security problem with tar -- it changed ownership
941 of any file pointed to by a symlink to 777 (like say libc....)
943 * cp and mv were very broken when moving directories. I have rewritten
944 them so they should now work as expected.
945 * sed now supports addresses (numeric or regexp, with negation) and
946 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
947 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
948 * Some cosmetic fixes to ls output formatting to make it behave more
950 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
951 * <fwv@myrtle.lahn.de>:
952 - Added gunzip -t, removed gunzip.c dead code,
953 - fixed several typos
954 - Glibc 2.0.7 and libc5 compile fixes
955 * Fixed a bug where 'mknod --help' would segfault.
958 -Erik Andersen, Jan 07, 2000
961 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
962 <tausq@debian.org>. 3 items off the TODO list!
963 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
964 * tail from GNU textutils-1.19, but adjusted
965 to suit my evil purposes. Costs 6k. I'll make it smaller
967 * on reboot, init called 'umount -a -n', which caused errors
968 when BB_MTAB was not enabled. Changed to 'umount -a', which does
970 * init will now try to run /sbin/getty if it is present (for easy
971 integration with the about-to-be-released tinylogin.)
972 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
973 * -l' was failing on long directories, since my_getid was leaking
974 one file descriptor per file. Oops.
975 * Fixed rebooting from init. I'd accidently left some debugging code
977 which blocked reboots.
978 * Fixed reboot, halt (and added poweroff) such that they handle it when
979 init is not at PID 1 (like when running in an initrd).
980 * Added a prelinary du implementation. Some parameter parsing
981 stuff still needs to be added. -beppu (John Beppu
983 * Implemented tee. -beppu Implemented head. -beppu
985 -Erik Andersen, Dec 10, 1999
988 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
990 * df will not exit on error, but will stat all mounted filesystems.
991 * Fixed tar so uid/gid/permissions on extracted tarballs will be
993 * Fixed find -name so it properly uses shell wildcard patterns
994 (i.e. `*', `?', and `[]') instead of regular expressions, which
995 was causing some confusing and unexpected behavior.
996 * Added klogd to syslogd, so now the log will contain both system and
998 * syslogd now creates the /dev/log socket to make sure it is there, and
999 is actually a socket with the right permissions.
1000 * I've taken a first step to making busybox not need the /proc
1001 filesystem. Most apps don't need it. Those that _require_ it,
1002 will complain if you enable them when you disable
1003 BB_FEATURE_USE_PROCFS.
1005 -Erik Andersen, Dec 5, 1999
1008 * Wrote a micro syslogd, and a logger util (to log things to the syslog
1009 from the command line or scripts) With both compiled in, costs 4k.
1010 * Fixed 'make install' so symlinks are installed in their proper
1011 * locations. Changed the build system slightly so that features can
1013 or disabled from the busybox.defs.h header file, without trying to
1014 compile in a source file named after that featue (unless that file
1016 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
1017 * -r' both work. dd now properly handles input beyond 1 block from
1018 * stdin. Fixed a bug where tar unpacked everything a directories.
1020 from createPath into mkdir where it belonged, thereby making tar
1022 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
1024 last file in the list.
1025 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
1027 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
1028 are presented properly.
1029 * Also added a TODO.
1032 -Erik Andersen, Nov 25, 1999
1035 * fixed dd so it properly defaults to stdin and stdout when no
1036 if= and of= are set (fix thanks to Eric Delaunay).
1037 * Don't try to close the file descriptor of a pipein tar. (fix also
1040 * Made createPath be quiet (again thanks to Eric Delaunay). If
1041 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
1042 command you define it as will be run if the init script exits.
1043 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
1044 * NFS support added to mount by Eric Delaunay. It costs 10k when
1046 in, but that is still a big win for those that use NFS.
1047 * Made 'rm -f' be silent for non-existant files (thanks to Eric
1048 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
1050 and acts as god intended gunzip and zcat to act. They answer
1051 --help and obey the '-c' flag.
1052 * Fixed a bug in mv which caused it to not move files when the
1055 * Fixed a decimal-instead-of-octal bug causing mkdir to make
1057 with very wrong permissions.
1058 * chmod would overwrite file permissions instead of modifying them.
1059 Now it properly modifies permissions.
1060 * Init now sends warnings destined for the console to /dev/console to
1062 they show up on whatever the active console it. Otherwise
1063 important messages (for example that the system is rebooting) were
1064 not seen when switched to a different VT.
1066 -Erik Andersen, Nov 17, 1999
1069 * gzip now obeys the principle of least surprise and acts like god
1071 (i.e. it accepts a file name, answers --help, and obeys the '-c'
1072 flag and only then outputs to stdout).
1073 * Fixed more.c to compile autowidth on sparc and set initial winsize
1074 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
1076 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
1077 * tar now accepts --help chmod, chown, and chgrp usage now works
1078 * General usage (i.e. --help) cleanups for most apps umount now parses
1079 * options correctly tar can now unpack tarballs containing device
1081 sockets, and fifos (though it can't pack them up) thanks to Matt
1082 Porter. Creating archives containing these is still left to the
1084 * fixed up the license in more.c to properly point to Bruce Perens.
1086 -Erik Andersen, Nov 11, 1999
1089 * ls -l now displays link names outside the current directory,
1090 Patch thanks to Eric Delaunay
1091 * init now properly handles sparc serial consoles and does a
1092 better job of finding the real console device rather than using
1093 /dev/console which doesn't support job control. Patch also thanks
1095 * more started to read from stdin after the last file was finished, and
1096 options were not parsed correctly (fix thanks to Eric Delaunay).
1097 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
1098 * rm wouldn't remove a symlink unless the symlink was valid. This was
1099 a side effect of the busybox 0.32 recursiveAction() fix. Things
1100 should now work correctly.
1101 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
1102 * it does. sed was appending a \n to the end of lines with
1104 Now it doesn't do that.
1105 * ls -l now bypasses libc6 nss when displaying user/group names.
1106 Now uses my_getpwuid and my_getgrgid.
1108 -Erik Andersen, Nov 8, 1999
1111 * Fixed a bug where init could hang instead of rebooting.
1112 * Removed some debugging noise from init.c
1113 * Fixed ln so it works now (it was very broken).
1114 * Fixed df so it won't segfault when there is no /etc/fstab,
1115 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
1116 is not installed (since they cannot fixup "/dev/root" to
1117 state the real root device name)
1118 * merged some redundant code from mtab.c/df.c into utility.c
1120 -Erik Andersen, Nov 5, 1999
1123 * More changes -- many thanks to Lineo for paying me to work on
1124 busybox. If you have any problems please let me know ASAP at
1125 andersen@lineo.com or andersee@debian.org
1126 * usage() now prints the BusyBox version. This will help folks
1127 realize that they are not in Kansas anymore.
1128 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
1129 * arguments. Now it doesn't do that. kill wasn't properly accepting
1130 * signal names. It does now. Added new apps chvt and deallocvt (I
1131 * should probably add open) Major rewrite of init.c. Code is now
1132 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
1133 * with full regular expressions!). Fixed a stupid seg-fault in sync
1134 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
1135 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
1136 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
1137 * cost of ~1.5k and the need for a rw /etc)
1138 folks to use a real /etc/mtab file instead of a symlink to
1139 /proc/mounts. mount, and umount will add/remove entries and df
1140 will now use /etc/mtab if BB_MTAB is defined.
1141 * Fixed a nice bug in recursiveAction() which caused it to infinitely
1142 hunt through /proc/../fd/* creating new file descriptors if it
1143 followed the /dev/fd link over to /proc. recursiveAction() now
1144 lstat's the file when followLinks==FALSE so it won't follow links
1145 as the name suggests. Fix thanks to Matt Porter
1146 <porter@debian.org>.
1149 -Erik Andersen, Nov 4, 1999
1152 * I added a changelog for version 0.30. adjusted find internals to
1153 * make it smaller, and removed
1155 * Fixed a segfault in ps when /etc/passwd or /etc/group
1156 are absent. Now will warn you and carry on.
1157 * Added in optional _real_ regular expression support (to be
1158 the basis for a future sed utility). When compiled in it adds
1159 3.9k, but makes grep much more capable.
1160 * Checked out using nftw(3) for recursive stuff, but unfortunatly
1161 it wasn't supported before GNU libc 2.1, and some folks use glibc
1162 2.0.7 since it is much smaller than that latest and greatest.
1164 -Erik Andersen, Oct 21, 1999
1167 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
1168 paying me to make these updates. If you have any problems with busybox,
1169 or notice any bugs -- please let me know so I can fix it. These
1173 * busybox can now invoke apps in two ways: via symlinks to the
1174 busybox binary, and as 'busybox [function] [arguments]...'
1175 * When invoked as busybox, the list of currently compiled in
1176 functions is printed out (no this is not bloat -- the list has
1177 to be there anyway to map invocation name to function).
1178 * busybox no longer parses command lines for apps or displays their
1179 usage info. Each app gets to handle (or not handle) this for
1181 * Eliminated monadic, dyadic, descend, block_device, and
1182 postprocess. It was cumbersome to have so many programs
1183 cobbled together in this way. Without them, the app is much
1185 * All shared code now lives in utility.c, and is properly
1186 ifdef'ed to be only included for those apps requiring it.
1187 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
1188 so now each app has the function prototype of (da-dum): extern
1189 int foo_main(int argc, char** argv); which speeds integration
1191 * Adjusted the Makefile to make it easier to
1192 {en|dis}able debugging.
1193 * Changed default compiler optimization to -Os
1194 (optimize for smaller binaries).
1197 * To cope with the new app function prototype and the removal of
1198 monadic, dyadic, etc, the following apps were re-written:
1199 * cat - Works same as always. chgrp, chmod, chown -
1200 * rewrite. Combined into a single
1201 source file. Absorbed patches from Enrique Zanardi
1202 <ezanard@debian.org> that removes the dependency on
1203 libc6 libnss* libraries.
1204 * cp - Can now do 'cp -a' can can copy devices,
1205 pipes, symlinks, as well as recursive or non-recursive
1207 * fdflush - adjusted to remove dependancy on struct
1208 * FileInfo. find - Now includes some basic regexp matching
1209 which will be the basic of a future mini-sed.
1210 * ln - Same functionality. mkdir - Added -p flag to
1211 * feature set. mv - rewrite. rm - Added -f flag to
1212 * feature set. rmdir - Same functionality. swapon,
1213 * swapoff - Combined into a single binary. No longer
1214 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
1216 * touch - Same functionality. date - adjusted with a patch
1217 * from Matthew Grant <grantma@anathoth.gen.nz>
1218 to accomodate glibc timezone support. I then ripped out GNU
1220 * mkswap -- new version merged from util-linux. Can now make
1222 * Replaced the old and star, unstar, and tarcat with the tar
1223 implementation from sash. Now tar behaves as god intended it
1224 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
1225 * dd -- rewritten. Can with with files, stdin, stdout. Added the
1226 * following new apps: loadfont -- added from debian boot floppies
1227 * chroot -- added based on a patch from Paolo Molaro
1228 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
1229 * simple strings ps -- I just wrote it. Has _no_ options at all,
1230 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
1232 internationalization and such to make them smaller.
1233 * sfdisk -- Added from util-linux (minus
1234 * internationalization and such). Probably some other
1235 * changes that I forgot to document...
1237 -Erik Andersen, Oct 20, 1999
1240 This version was a messy pre-alpha. stay away or it will bite you.
1241 -Erik Andersen, Sep 24, 1999
1244 mini-netcat (mnc) rewritten.
1247 Mount now supports -a, and -t auto.
1248 Mount now updates mtab correctly for 'ro'.
1249 More checks screen rows size, outputs bytes percentage.
1250 Printf added as module.
1252 Touch now creates files. -c option for no create.
