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

115 * Vladimir Oleynik -- traceroute
116 * Erik Andersen -- pidof
119 * David Schleef, Erik Andersen, Stuart Hughes -- depmod.pl
120 This is a replacement for the depmod program from the modutils
121 package, but is fully cross platform and is designed to run on
122 your host system (not on the target).
126 -- fixed busybox.spec so it should now work on redhat systems
127 -- fixed dos2unix and unix2dos so they should work once again
128 -- Adjustments to make busybox more uClinux friendly. Busybox
129 should now work on uClinux systems without needing and source
130 code changes (applets that won't work on uClinux systems are
131 now automagicaly disabled).
132 -- various things (cleanups, libc compatibility work, etc, etc)

153 -- Adjustments to make busybox more uClinux friendly
155 -- Fixed gzip so when a filename is '-' it will use stdin/stdout
156 -- dpkg rewrite. Should now be compatable with the real dpkg,
157 but needs more testing.
158 -- Updates to archiving tools (gunzip/gzip/cpio/ar/etc)
159 -- Rewrote uuencode, will allow base64 encoding to be used by wget
161 -- Fixed tr to support 'tr a-z A-Z' syntax,
162 -- Many ash corrections, optimizations, and cleanups.

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

531 * Fixed tar handling of stdin and stdout
532 * Renamed "internal.h" to the more sensible "busybox.h"
533 * Preliminary support for GNU HURD.
534 * Updated my devps and devmtab kernel patches for the latest 2.2.x
535 kernel, for those wanting to go proc-less.
536 * Tons of other bugfixes.
539 -Erik Andersen, 25 September 2000
544 * Better portability. Now should compile cleanly with libc5,
545 GNU libc 2.0 and 2.1, and various Linux kernels including
546 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
547 to make /proc/mounts behave included in the kernel-patches dir).
548 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
549 local files that matched tarball contents!!! Fix thanks
550 to Marius Groeger <mgroeger@sysgo.de>
551 * Fixed a nasty bug in tar when could mess up saved symlinks.
552 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
553 thanks to Daniel Quinlan <quinlan@transmeta.com>
554 * Updates to handle Linux 2.4.0 kernels (kludged around the
555 "none" entries in /proc/mounts, added a hack to make sysinfo
556 work with both old and new kernels).
557 * Fixed insmod module option parsing for options lacking an '='.
558 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
559 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
560 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
561 * Several fixes from Marius Groeger <mag@sysgo.de>
562 - Added support for "sh -c command args..."
563 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
564 - Added shell environment variable substitution
565 - Added the "read" shell builtin.
566 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
567 used to create an infinite loop: ls, cursor up, left, down.
568 * Added support for being a login shell, so things like
569 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
570 invoke the shell. Now you can use BusyBox as a login shell.
571 * ls.c now ignores '-g', since some ftp clients like that sort
572 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
573 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
574 it always sets the controlling terminal before running any programs
575 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
576 - Fixed tr so it recognizes standard escape sequences.
577 Merged common escape seq. code from tr and echo into utility.c.
578 - Major work in updating/cleaning up the docs, and getting the
579 new SGML based docs into shape.
581 - BusyBox should now poweroff when asked to do so.
582 - Fixed 'ln -n' and 'ln -s' so they both work properly.
583 * Reorganized signal names in kill.c for better architecture support
584 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
585 * In 0.43, backspace and delete worked properly, but with 0.45,
586 it just echoed a ^? for backspace, and ^H for control-h. This
587 was due to a broken macro in init.c, that is now fixed.
588 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
589 couldn't maintain it very well, so including it was not really
590 very appropriate. Those wanting an fdisk are invited to
591 grab a copy from util-linux.
592 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
593 then be loaded in by 'loadkmap' -- submitted by
594 Arne Bernin <arne@matrix.loopback.org>
595 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
596 * Brand, new versions of grep and sed which use libc regex routines,
597 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
598 "regexp.[ch]" files have been removed. Much help on these from
602 -Erik Andersen, 11 July 2000
606 * Now compiles vs libc5 (which can save lots of space for
608 * Added CONFIG_FEATURE_TRIVIAL_HELP which compiles out most all of the
609 help messages (i.e --help). Saves 17k over a full compile.
610 * Added cut and tr from minix, since due to the license change,
611 we can now use minix code. Minix tr saves 4k.
612 * insmod now works. It costs 29k, but imagine an initrd with a
613 staticly linked busybox containing only insmod and sh, a few /dev
614 entries, and a kernel module or two... It doesn't get smaller
615 then this folks (I pity the fool that writes insmod in asm ;-).
616 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
617 * Added a mini ar archive utility, especially written for BusyBox by
618 Glenn McGrath <bug1@netconnect.com.au>
619 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
620 * Added setkeycodes, for those that have wierd keyboard buttons.
621 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
622 <ams@trillian.itslinux.org> for contributing these.
623 * Added 'grep -v' option (inverted search) and updated
624 docs accordingly. -beppu
626 * Replaced the telnet implementation with one written by
627 Tomi Ollila <too@iki.fi> It works great and costs 3k.
628 * BusyBox sh (lash) now supports being used as a standalone shell. When
629 CONFIG_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
630 be invoked as shell internals. Best used when compiling staticly
632 * BusyBox sh (lash) internals now behave as expected wrt pipes
634 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
635 * Fixed update segfault
636 * Fixed mknod -- minor number was always 0
637 * Fixed tar option parsing, so both "tar xvf foo.tar" and
638 "tar -xvf foo.tar" now work (i.e. no "-" before options)
639 (this was very broken in 0.43).
640 * Several contributions from Randolph Chung <tausq@debian.org>.
641 * cp/mv now accepts the -f flag
642 * tail can now accept -<num> commands (e.g. -10) for better
643 compatibility with the standard tail command
644 * added a simple id implementation; doesn't support sup. groups yet
645 * logname used getlogin(3) which uses utmp. Now it doesn't.
646 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
647 * Add support for "noatime" and "nodiratime" mount flags to mount.
648 * Changed 'umount -f' to mean force, and actually use umount2.
649 * Changed 'umount -l' to mean "Do not free loop device".
650 * Fixed basename to support stripping of suffixes. Patch thanks
651 to xiong jianxin <jxiong@uiuc.edu>
652 * cp -fa now works as expected for symlinks (it didn't before)
653 * zcat now works (wasn't working since option parsing was broken)
654 * Renamed "mnc" to the more correct "nc" (for netcat).
655 * Makefile intelligence updates
656 * Changed the way init parses /etc/inittab entries to avoid problems
657 with commands that contain colons in them. Fix thanks to
658 Pavel Roskin <proski@gnu.org>
659 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
660 Fix thanks to Pavel Roskin <proski@gnu.org>
661 * Made "killall" complain (not error and exit) about processes that it
662 cannot find by name -- Pavel Roskin <proski@gnu.org>
663 * Fixed more and ps to have sensible terminal width defaults, thanks
665 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
666 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
667 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
668 * Fixed segfault caused by "touch -c"
669 * Fixed segfault caused by "rm -f"
670 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
671 and "--" support from Pavel Roskin.
672 * Fixed segfault caused by "cp -a -a" and similar abuses.
673 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
674 * "which" rewritten to use stat(). Fixes to improve its compatability
675 with traditional implementations -- Pavel Roskin.
676 * "mount" now reports errors from nfsmount() and assumes NFS mount
677 if ':' is present in the device name - Pavel Roskin
678 * Fixed exit status for killall - Pavel Roskin
679 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
680 * Fixed 'mount -a' so it works as expected.
681 * Implemented 'ls -R' (enabled by enabling CONFIG_FEATURE_LS_RECURSIVE)
682 * Implemented "ping -s", fixed error messages and argument parsing -
684 * Syslogd will not go to background if "-n" is given. Better help
685 and argument checking -- Pavel Roskin
686 * Fixed a small bug that could cause tar to emit warning messages
687 and not extract the first file in a directory in some cases
688 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
689 for helping track this one down.
691 * Fixed grep "Line too long" problem -- John Beppu
692 * Fixed 'grep -q -i B some_file' so it works
693 * math takes input from stdin if no args are given. -- John Beppu
694 * math was renamed to dc. Although it deviates from dc's behaviour,
695 this will probably be remedied in the future. -- John Beppu
698 -Erik Andersen, June 21, 2000
702 Previously, an erronous announcement of BusyBox 0.44 was made, so to
703 avoid possible confusion, we are skipping straight to 0.45, and calling
710 * Major update to the provided documentation.
711 * Busybox now includes a shell! It currently costs 7.5 k (plus an
712 additional 2.5 k if you compile in command line editing). Handles
713 job control, has the usual set of builtins, and does everything
714 except for handling programming statements (if, while, etc...)
715 * Busybox can now work perfectly when /proc is disabled, thereby
716 saving a bunch of memory (kernel /proc support is not thin). This
717 is done by making use of some nice kernel patches I wrote up to
718 support the features that busybox requires and that /proc usually
719 provides. To enable this, turn on CONFIG_FEATURE_USE_DEVPS_PATCH and
720 patch your kernel with the devps patch in the kernel-patches/
722 * Wrote basename, dirname, killall, and uptime.
723 * tar has been completely rewritten by me. Both tar creation and
724 extraction are now well behaved. Costs 7.6k with all optional
725 tar features enabled, and 5k for just tar extraction support.
726 * Added freeramdisk, which will free up all memory associated
727 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
728 and then adjusted a bit by me.
729 * Added tr from John Lombardo <john@deltanet.com>
730 * Added echo and test (from me).
731 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
732 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
733 * Several fixes from Pavel Roskin <proski@gnu.org>:
734 - When `tail' fails to open a file it now exits.
735 - When `syslogd' is given the `-n' option it should still use
736 fork() for running klogd.
737 * nslookup types are now changed to u_int32_t (instead of uint32_t)
738 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
739 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
740 to count hard-linked files more then once). Many thanks to
741 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
742 * Removed /proc dependancies for init and free (while maintaining
743 exactly the same functionality). /proc takes up 90k of kernel
744 space, so it is nice to avoid using it at all costs.
745 * init no longer tries to mount /proc (unless there is less the 1 meg
746 free). Use of /proc (or not) is policy that should be set up in
747 /etc/fstab (or in hardcoded scripts), not in init.
748 * Fixed rebooting when init runs as an initrd.
749 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
750 - update.c rewritten to look more like update-2.11
751 - moveed the inode hash out of du.c and into utility.c to make
752 it a common resource that can be used by other apps.
753 - cp_mv.c now checks inodes to see if a source and dest are
754 the same, and prints an error (instead of endlessly looping).
755 - mv now attempts to do a rename, and will fall back to doing
756 a copy only if the rename fails.
757 - Syslogd now supports multiple concurrent connections
758 * Several fixes from Pavel Roskin <proski@gnu.org>:
759 - Fixes to sort. Removed "-g", fixed and added "-r"
760 - Fixes to the makefile for handling "strip"
761 * An initial telnet implementation was added by
762 Randolph Chung <tausq@debian.org>.
763 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
764 * ps now supports CONFIG_FEATURE_AUTOWIDTH, and can adjust its width
765 to match the terminal (defaults to width=79 when this is off).
766 * ps now accepts (and ignores) all options except for "--help" (which
767 as would be expected displays help).
768 * Fixed mount'ing loop devices when the filesystem type was not
769 specified. It used to revert to non-loop after the first try.
770 * all mallocs now use xmalloc (and so are OOM error safe), and
771 the common error handling saves a few bytes. Thanks to
772 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
773 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
774 * Fix symlink following bug in chmod -R and friends.
775 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
776 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
785 * Fairly massive restructuring of umount.c to deal with remounting
786 busy devices read-only. Adds a -r option to control that; it is
787 optionally compiled in with CONFIG_FEATURE_REMOUNT
788 * Added a bunch of functions to mtab.c to interact with the
789 {get,set,end}mntent interface; as it turns out, those functions do
790 not appear to be re-entrant, and that causes a lot of problems with
791 the way umount was originally written.
792 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
793 to be more consistent with sysvinit
794 * Changes to init.c to use the new -r option to umount. Also increased
795 the sleep time between the time the TERM and KILL signals are sent
800 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
801 extensively rewritten from the original cp.c.
802 * Fixed cp and mv so if the source and destination are a the
803 same directory it will print an error and continue.
804 * Also added a warning message to the `mv' usage string saying that
805 this is not GNU mv, and it will break hard links. cp also breaks
807 * ln.c: implemented `-n' switch, no-deref symlinks.
808 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
809 * name buffer overrun guards to prevent future crashes.
810 - Always check exit status.
811 - Purge all use of `creat()', replace with `open()'.
813 - recursiveAction was overriding the value of followLinks thus
815 - isDirectory now takes a followLinks boolean, updated all callers
816 - copyFile had the followLinks logic reversed.
817 * messages.c: New file. Put common error message strings all in
818 one place in an attempt to shrink the binary a little.
823 * changed fsck_minix.c to reduce its .bss size significantly
825 * Made tar creation support in busybox tar optional. You no longer
826 * _have_ to put a "-" in front of tar options. Tar could inadvertently
827 * change permissions and ownership on
828 certain directories pointed to by symlinks.
829 * Made grep and grep -h do the right thing wrt printing
830 the file name (it failed to print files names in many cases).
831 * Fix a namespace aliasing problem wereby if du was built in, the
832 symlink for both du and dutmp would be installed, or then rm was
833 built in, the symlinks for both rm and rmmod would be installed.
834 * Added a closelog() to init.c after loging -- fix thanks to
835 Taketoshi Sano <kgh12351@nifty.ne.jp>
836 * Rewrote and simplified logger. Added the "-t" option, and made it
837 behave itself a bit better.
838 * Optional support contributed by Ben Collins <bcollins@debian.org>
839 for the kernel init chroot patch by Werner Almesberger, which
840 allows init to chroot to a new device, and umount the old one.
841 * Fixed bug that wouldn't let one chown a symlink -- it would
842 always dereference before. -beppu
843 * Fixed a bug where init could have reference already freed memory.
844 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
845 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
846 * Added (and documented) "-n" option for head
847 * Cleanup for a number of usage messages -- also
848 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
849 * Cosmetic fix to busybox.c (Don't print a comma at the
850 end of line if there are no more application names).
851 * Fixed a stupid bug in "head" option handling ("head -n"
853 * Moved commonly used functions "xmalloc()" and "exit()"
854 to utility.c (with proper #ifdef's).
855 * Created a tiny tail implementation, removing -c, -q, -v, and making
856 tail -f work only with a single file. This reduced tail from 6k to
857 2.4k. The bigger/more featured tail can still be had by disabling
858 CONFIG_FEATURE_SIMPLE_TAIL in busybox.defs.h
859 * Ping now falls back to doing the right thing if /etc/protocols
861 * Fixed mount and umount. Previously they could leak loop device
862 allocations, causing the system to quickly run out. Fix for umount
863 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
864 * ls formatting on eight charactor user names fixed by
865 Randolph Chung <tausq@debian.org>.
866 * cp could, when copying symlinks, change permissions of the
867 files pointed to by the symlinks.
868 * Several fixes from Pavel Roskin <proski@gnu.org>:
869 - `chown' with 1 argument displayed the error incorrectly
870 - `fdflush', `length' and `printf' crashed if run without arguments
871 - `fdflush' tried to flush itself using *argv
872 - added "skip" and "seek" to dd.
873 - ls no longer messus up output when combining files and
874 directories on the command line
875 * swapoff -a was not working. Now it is.
876 * init did not cleanly unmount filesystems on reboot. Now it does.
877 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
879 * Some architectures (PowerPc) assume chars are unsigned, so they could
880 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
881 * Began converting error handling to use some common routines
883 * syslogd now has better message handling and ignores SIGHUP.
884 * install.sh had a bug preventing installation to the specified
885 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
886 * You can now spefify alternative strip commands -- change
887 also from Gilbert Coville.
893 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
894 by Edward Betts <edward@debian.org>
895 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
896 type commands (file in a directory to another directory) from
898 * Fixed a logger bug that caused garbage to be written to the syslog
899 (unless you used busybox syslog, which hid the bug). Thanks to
900 Alex Holden <alex@linuxhacker.org> for the fix.
901 * /bin/true and /bin/false were echoing a blank line when run.
903 * mkdir -p would print an error when asked to mkdir an existing dir
904 with no interveining subdirectories.
905 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
906 * and support in umount for loop
907 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
908 <bcollins@debian.org>
909 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
910 * fullWrite() not only if CONFIG_TAR is defined, but also
911 if CONFIG_CP or CONFIG_MV are (fullWrite() is referenced by copyFile())
912 * add some compiler optimizations to further reduce executable size
913 (as a side note, on my machines the largest code is generated
914 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
916 * Compile now won't fail if busybox.def.h defines
917 CONFIG_FEATURE_INITRD but not CONFIG_INIT. (init_main used to be
918 referenced, but not compiled)
919 * Fixed a bug in setting TERM for serial console support. TERM now
920 defaults to "ansi" for serial consoles.
921 * Fixed a bug in handling the CONSOLE env. variable for serial
924 -Erik Andersen, Jan 15, 2000
927 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
928 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
929 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
930 for loading application character maps for Unicode fonts.
931 * Major init re-work. init now supports inittab (slightly different
932 but similar to sysvinit), allowing me to get all the policy out of
933 init and into the conf file. It works just fine without inittab
934 being present, but if you dont like the default behavior you can
935 now do something about it. Init is much cleaner as a result.
936 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
937 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
938 * failure of 'logger -p'. -erik Added the -s option to du -beppu
939 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
940 with the 2.0.x Linux kernel.
941 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
943 * Grep -i previously failed on UPPER CASE patterns due to a silly
944 regexp implementation bug that is now fixed.
945 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
946 * Fixed a bug where tar would not set the user and group on device
948 * Fixed a bug where tar would not restore the time to files. Fixed a
949 * major security problem with tar -- it changed ownership
950 of any file pointed to by a symlink to 777 (like say libc....)
952 * cp and mv were very broken when moving directories. I have rewritten
953 them so they should now work as expected.
954 * sed now supports addresses (numeric or regexp, with negation) and
955 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
956 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
957 * Some cosmetic fixes to ls output formatting to make it behave more
959 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
960 * <fwv@myrtle.lahn.de>:
961 - Added gunzip -t, removed gunzip.c dead code,
962 - fixed several typos
963 - Glibc 2.0.7 and libc5 compile fixes
964 * Fixed a bug where 'mknod --help' would segfault.
967 -Erik Andersen, Jan 07, 2000
970 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
971 <tausq@debian.org>. 3 items off the TODO list!
972 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
973 * tail from GNU textutils-1.19, but adjusted
974 to suit my evil purposes. Costs 6k. I'll make it smaller
976 * on reboot, init called 'umount -a -n', which caused errors
977 when CONFIG_MTAB was not enabled. Changed to 'umount -a', which does
979 * init will now try to run /sbin/getty if it is present (for easy
980 integration with the about-to-be-released tinylogin.)
981 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
982 * -l' was failing on long directories, since my_getid was leaking
983 one file descriptor per file. Oops.
984 * Fixed rebooting from init. I'd accidently left some debugging code
986 which blocked reboots.
987 * Fixed reboot, halt (and added poweroff) such that they handle it when
988 init is not at PID 1 (like when running in an initrd).
989 * Added a prelinary du implementation. Some parameter parsing
990 stuff still needs to be added. -beppu (John Beppu
992 * Implemented tee. -beppu Implemented head. -beppu
994 -Erik Andersen, Dec 10, 1999
997 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
999 * df will not exit on error, but will stat all mounted filesystems.
1000 * Fixed tar so uid/gid/permissions on extracted tarballs will be
1002 * Fixed find -name so it properly uses shell wildcard patterns
1003 (i.e. `*', `?', and `[]') instead of regular expressions, which
1004 was causing some confusing and unexpected behavior.
1005 * Added klogd to syslogd, so now the log will contain both system and
1007 * syslogd now creates the /dev/log socket to make sure it is there, and
1008 is actually a socket with the right permissions.
1009 * I've taken a first step to making busybox not need the /proc
1010 filesystem. Most apps don't need it. Those that _require_ it,
1011 will complain if you enable them when you disable
1012 CONFIG_FEATURE_USE_PROCFS.
1014 -Erik Andersen, Dec 5, 1999
1017 * Wrote a micro syslogd, and a logger util (to log things to the syslog
1018 from the command line or scripts) With both compiled in, costs 4k.
1019 * Fixed 'make install' so symlinks are installed in their proper
1020 * locations. Changed the build system slightly so that features can
1022 or disabled from the busybox.defs.h header file, without trying to
1023 compile in a source file named after that featue (unless that file
1025 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
1026 * -r' both work. dd now properly handles input beyond 1 block from
1027 * stdin. Fixed a bug where tar unpacked everything a directories.
1029 from createPath into mkdir where it belonged, thereby making tar
1031 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
1033 last file in the list.
1034 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
1036 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
1037 are presented properly.
1038 * Also added a TODO.
1041 -Erik Andersen, Nov 25, 1999
1044 * fixed dd so it properly defaults to stdin and stdout when no
1045 if= and of= are set (fix thanks to Eric Delaunay).
1046 * Don't try to close the file descriptor of a pipein tar. (fix also
1049 * Made createPath be quiet (again thanks to Eric Delaunay). If
1050 * CONFIG_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
1051 command you define it as will be run if the init script exits.
1052 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
1053 * NFS support added to mount by Eric Delaunay. It costs 10k when
1055 in, but that is still a big win for those that use NFS.
1056 * Made 'rm -f' be silent for non-existant files (thanks to Eric
1057 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
1059 and acts as god intended gunzip and zcat to act. They answer
1060 --help and obey the '-c' flag.
1061 * Fixed a bug in mv which caused it to not move files when the
1064 * Fixed a decimal-instead-of-octal bug causing mkdir to make
1066 with very wrong permissions.
1067 * chmod would overwrite file permissions instead of modifying them.
1068 Now it properly modifies permissions.
1069 * Init now sends warnings destined for the console to /dev/console to
1071 they show up on whatever the active console it. Otherwise
1072 important messages (for example that the system is rebooting) were
1073 not seen when switched to a different VT.
1075 -Erik Andersen, Nov 17, 1999
1078 * gzip now obeys the principle of least surprise and acts like god
1080 (i.e. it accepts a file name, answers --help, and obeys the '-c'
1081 flag and only then outputs to stdout).
1082 * Fixed more.c to compile autowidth on sparc and set initial winsize
1083 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
1085 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
1086 * tar now accepts --help chmod, chown, and chgrp usage now works
1087 * General usage (i.e. --help) cleanups for most apps umount now parses
1088 * options correctly tar can now unpack tarballs containing device
1090 sockets, and fifos (though it can't pack them up) thanks to Matt
1091 Porter. Creating archives containing these is still left to the
1093 * fixed up the license in more.c to properly point to Bruce Perens.
1095 -Erik Andersen, Nov 11, 1999
1098 * ls -l now displays link names outside the current directory,
1099 Patch thanks to Eric Delaunay
1100 * init now properly handles sparc serial consoles and does a
1101 better job of finding the real console device rather than using
1102 /dev/console which doesn't support job control. Patch also thanks
1104 * more started to read from stdin after the last file was finished, and
1105 options were not parsed correctly (fix thanks to Eric Delaunay).
1106 * more will now use the terminal size if CONFIG_FEATURE_AUTOWIDTH is on.
1107 * rm wouldn't remove a symlink unless the symlink was valid. This was
1108 a side effect of the busybox 0.32 recursiveAction() fix. Things
1109 should now work correctly.
1110 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
1111 * it does. sed was appending a \n to the end of lines with
1113 Now it doesn't do that.
1114 * ls -l now bypasses libc6 nss when displaying user/group names.
1115 Now uses my_getpwuid and my_getgrgid.
1117 -Erik Andersen, Nov 8, 1999
1120 * Fixed a bug where init could hang instead of rebooting.
1121 * Removed some debugging noise from init.c
1122 * Fixed ln so it works now (it was very broken).
1123 * Fixed df so it won't segfault when there is no /etc/fstab,
1124 * If CONFIG_MTAB is not defined, df and mount will whine if /etc/fstab
1125 is not installed (since they cannot fixup "/dev/root" to
1126 state the real root device name)
1127 * merged some redundant code from mtab.c/df.c into utility.c
1129 -Erik Andersen, Nov 5, 1999
1132 * More changes -- If you have any problems please let me know ASAP at
1134 * usage() now prints the BusyBox version. This will help folks
1135 realize that they are not in Kansas anymore.
1136 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
1137 * arguments. Now it doesn't do that. kill wasn't properly accepting
1138 * signal names. It does now. Added new apps chvt and deallocvt (I
1139 * should probably add open) Major rewrite of init.c. Code is now
1140 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
1141 * with full regular expressions!). Fixed a stupid seg-fault in sync
1142 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
1143 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
1144 * umount -a no longer umounts /proc Added CONFIG_MTAB, allowing (at the
1145 * cost of ~1.5k and the need for a rw /etc)
1146 folks to use a real /etc/mtab file instead of a symlink to
1147 /proc/mounts. mount, and umount will add/remove entries and df
1148 will now use /etc/mtab if CONFIG_MTAB is defined.
1149 * Fixed a nice bug in recursiveAction() which caused it to infinitely
1150 hunt through /proc/../fd/* creating new file descriptors if it
1151 followed the /dev/fd link over to /proc. recursiveAction() now
1152 lstat's the file when followLinks==FALSE so it won't follow links
1153 as the name suggests. Fix thanks to Matt Porter
1154 <porter@debian.org>.
1157 -Erik Andersen, Nov 4, 1999
1160 * I added a changelog for version 0.30. adjusted find internals to
1161 * make it smaller, and removed
1163 * Fixed a segfault in ps when /etc/passwd or /etc/group
1164 are absent. Now will warn you and carry on.
1165 * Added in optional _real_ regular expression support (to be
1166 the basis for a future sed utility). When compiled in it adds
1167 3.9k, but makes grep much more capable.
1168 * Checked out using nftw(3) for recursive stuff, but unfortunatly
1169 it wasn't supported before GNU libc 2.1, and some folks use glibc
1170 2.0.7 since it is much smaller than that latest and greatest.
1172 -Erik Andersen, Oct 21, 1999
1175 Major changes -- lots of stuff rewritten. If you have any problems
1176 with busybox, or notice any bugs -- please let me know so I can fix
1177 it. These changes include:
1180 * busybox can now invoke apps in two ways: via symlinks to the
1181 busybox binary, and as 'busybox [function] [arguments]...'
1182 * When invoked as busybox, the list of currently compiled in
1183 functions is printed out (no this is not bloat -- the list has
1184 to be there anyway to map invocation name to function).
1185 * busybox no longer parses command lines for apps or displays their
1186 usage info. Each app gets to handle (or not handle) this for
1188 * Eliminated monadic, dyadic, descend, block_device, and
1189 postprocess. It was cumbersome to have so many programs
1190 cobbled together in this way. Without them, the app is much
1192 * All shared code now lives in utility.c, and is properly
1193 ifdef'ed to be only included for those apps requiring it.
1194 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
1195 so now each app has the function prototype of (da-dum): extern
1196 int foo_main(int argc, char** argv); which speeds integration
1198 * Adjusted the Makefile to make it easier to
1199 {en|dis}able debugging.
1200 * Changed default compiler optimization to -Os
1201 (optimize for smaller binaries).
1204 * To cope with the new app function prototype and the removal of
1205 monadic, dyadic, etc, the following apps were re-written:
1206 * cat - Works same as always. chgrp, chmod, chown -
1207 * rewrite. Combined into a single
1208 source file. Absorbed patches from Enrique Zanardi
1209 <ezanard@debian.org> that removes the dependency on
1210 libc6 libnss* libraries.
1211 * cp - Can now do 'cp -a' can can copy devices,
1212 pipes, symlinks, as well as recursive or non-recursive
1214 * fdflush - adjusted to remove dependancy on struct
1215 * FileInfo. find - Now includes some basic regexp matching
1216 which will be the basic of a future mini-sed.
1217 * ln - Same functionality. mkdir - Added -p flag to
1218 * feature set. mv - rewrite. rm - Added -f flag to
1219 * feature set. rmdir - Same functionality. swapon,
1220 * swapoff - Combined into a single binary. No longer
1221 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
1223 * touch - Same functionality. date - adjusted with a patch
1224 * from Matthew Grant <grantma@anathoth.gen.nz>
1225 to accomodate glibc timezone support. I then ripped out GNU
1227 * mkswap -- new version merged from util-linux. Can now make
1229 * Replaced the old and star, unstar, and tarcat with the tar
1230 implementation from sash. Now tar behaves as god intended it
1231 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
1232 * dd -- rewritten. Can with with files, stdin, stdout. Added the
1233 * following new apps: loadfont -- added from debian boot floppies
1234 * chroot -- added based on a patch from Paolo Molaro
1235 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
1236 * simple strings ps -- I just wrote it. Has _no_ options at all,
1237 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
1239 internationalization and such to make them smaller.
1240 * sfdisk -- Added from util-linux (minus
1241 * internationalization and such). Probably some other
1242 * changes that I forgot to document...
1244 -Erik Andersen, Oct 20, 1999
1247 This version was a messy pre-alpha. stay away or it will bite you.
1248 -Erik Andersen, Sep 24, 1999
1251 mini-netcat (mnc) rewritten.
1254 Mount now supports -a, and -t auto.
1255 Mount now updates mtab correctly for 'ro'.
1256 More checks screen rows size, outputs bytes percentage.
1257 Printf added as module.
1259 Touch now creates files. -c option for no create.
