2 * Evin Robertson -- new pivot_root applet
3 * Bjorn Wesen -- new ifconfig and route applet (taken from
4 work done be Axis Communications).
5 * Vladimir N. Oleynik -- new stty applet
6 * Kenneth Chalmers and Erik Andersen -- fixed ln so it
7 behaves when given no arguments (prints usage) and when
8 given just one arg (tries to make a link in the cwd).
10 <lots of other things -- fixme>
13 -Erik Andersen, not yet released
17 * Matt Kraai -- new sort.c
18 * Matt Kraai -- new tail.c
19 * Glenn McGrath -- new 'dpkg-deb' applet
20 * Glenn McGrath -- new ar code
21 * spoon -- new watchdog applet
22 * Vladimir N. Oleynik <dzo@simtreas.ru> -- fixed cmdedit.c so now
23 scrolling and tab completion in lash work properly. Also several
24 byte saving optimizations.
25 * Erik Andersen -- disabled many less commonly used applets by default
26 * Mark Whitley -- more thrashing about to get clean perror_msg usage
27 * Matt Kraai -- new command line munging
28 * Larry Doolittle -- keep some locales from messing up busybox.sh
29 * Matt Kraai -- cleaned up dd and tail with new parse_number routine
30 * Mark Whitley -- remove debugging messages from deallocvt
31 * Matt Kraai and Mark Whitley -- new document "How to Add a New Applet
33 * David Douthitt -- fixed "grep -qv" bug
34 * Larry Doolittle -- fixed insmod bug with old kernels
35 * Matt Kraai -- logger remixed to use getopt, selection of stdin made
37 * Erik Andersen -- many more internal symbols classified static to
38 avoid namespace pollution
39 * Matt Kraai -- nc listening support
40 * Erik Andersen -- made sed understand arbitrary regexp delimiters
41 * Matt Kraai et al. -- more tar improvements and bug fixes, now
42 handles regexp file exclusion
43 * Larry Doolittle -- new script (multibuild.pl) to automate build rule
45 * Matt Kraai -- update/cleanup of the docs on how to use init
46 * Erik Andersen -- renamed all sh.c symbols per the style guide,
47 better if-then-else-fi handling
48 * Erik Andersen -- cleaner division of labor between cmdedit.c and sh.c
49 * Larry Doolittle -- shell data structure cleanup, fixed buglets
50 in read, exec, and piped builtins
51 * Erik Andersen -- md5sum was broken in 0.48. Now fixed (and doesn't
52 use getline, shrinking static compiles (since nothing else used it).
53 * ?? -- squashed memory leak in shell prompt handling
54 * Mark Whitley -- Updates to style guide
55 * Mark Whitley -- Big cleanup in utility.c: style guide compliance,
56 de-macro-ifying some variables and functions
57 * Erik Andersen -- ls now honors BB_FEATURE_AUTOWIDTH so it can find
58 the width and height of the console.
59 * Erik Andersen -- insmod now ignores -L and accepts the -o option.
60 * Erik Andersen -- updates so you can now select from the Makefile
61 whether or not to use the system's passwd and group functions.
62 Since most systems use GNU libc, this can save you from having to
63 install the /etc/nsswitch.conf configuration file and the required
64 libnss_* libraries. Adds 1.5k. You can now, also, disable this,
65 causing busybox to use the system's pwd.h and grp.h functions.
68 -Erik Andersen, 27 January 2001
72 * Glenn McGrath -- tar now supports uncompressing tar files,
73 define BB_FEATURE_TAR_GZIP to use the -z option.
74 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
75 return EXIT_SUCCESS or EXIT_FAILURE to the system.
76 Now TRUE and FALSE are set to the C standard where TRUE=1.
77 * me -- Fixed uname problem causing the kernel version to be
78 mis-detected (causing problems with poweroff, init,
80 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
81 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
82 and StrongArm, and suport for lsmod on older 2.0.x kernels.
83 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
84 an included shell script called unrpm as a front end to it. There's
85 also a shell script called undeb included for debian packages.
86 * Matt Kraai -- fix an infinite loop with ls -aR
87 * Larry Doolittle -- Shaved off about 100 bytes and 200 bytes heap
88 from date.c. Also document the "-d" option in the usage message.
89 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
90 (it was reading the whole thing and then writing it out). Also
91 updated usage information (was missing conv=notrunc) and added
93 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
94 pristine source directory -- where all the .o files and such are
95 not placed into the source tree. Thanks Larry!
96 * Larry Doolittle -- use the applet definitions in applets.h
97 to autogenerate the applet function and usage prototypes.
98 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
99 fixed a bug breaking tar --exclude.
100 * Jonas Holmberg -- echo option handling made GNU-echo compatible
101 * Aleksey Demidov <asd@ixcelerator.com> -- date option handling made
103 * me -- Progress meter (optional) in wget
104 * Doolittle/me -- programs invoked by full path name take
105 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
106 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
107 binary search instead of linear search. Much faster!
108 * new applets: cmp readlink
109 * Mark Whitley -- Removed advertising clause of Berkeley license
110 according to decision by the Regents of the University of
111 California; included reference
112 * tail's confusing special treatment of single digit options removed;
113 people should use -n instead
114 * Larry Doolittle -- \r handled now in echo and tr
115 * Matt Kraai -- rewrite of uniq
116 * Mark Whitley -- remix of xargs
117 * Jim Gleason <jimg@lineo.com> -- fixed tar so it no longer breaks
119 * Matt Kraai -- logger now logs all arguments, not just the first
120 * Gennady Feldman -- syslogd no longer logs to localhost if compiled
121 for remote logging...
122 * Richard June <rjune@ims1.imagestream-is.com> -- support for 'gzip -d'
123 * various artists -- Other good stuff that I forgot to document.
126 -Erik Andersen, 13 December 2000
130 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
131 your system. Anyone using 0.46 syslogd should upgrade.
132 * Renamed busybox.defs.h to the more sensible "Config.h"
133 * Improved portability between different libcs.
134 * Many apps ported to use getopt()
135 * Common handling of '--help'
136 * All usage messages centralized.
137 * Added a bunch of new commands:
138 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
139 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
140 <crosenth@covad.com> and Covad Communications
141 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
142 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
143 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
144 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
145 * 'xargs' (written by me)
146 * 'expr' contributed by Edward Betts <edward@debian.org>, based
148 * lsmod now uses the query_module syscall, rather then /proc (me)
149 * syslogd can now log messages to remote hosts -- patch thanks
150 to Gyepi Sam <gyepi@praxis-sw.com>
151 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
152 * 'make install' now creates relative symlinks, and added a new
153 'make install-hardlinks' target to (tada) install hardlinks.
154 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
155 It now weighs only 2.25k (3k when full featured). The code is
156 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
157 * Add optional ls file sorting, thanks to a patch from
158 Sterling Huxley <sterling@europa.com>
159 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
160 now work (previously it thought -r was an option). Doh!
161 * Fixed tar handling of stdin and stdout
162 * Renamed "internal.h" to the more sensible "busybox.h"
163 * Preliminary support for GNU HURD.
164 * Updated my devps and devmtab kernel patches for the latest 2.2.x
165 kernel, for those wanting to go proc-less.
166 * Tons of other bugfixes.
169 -Erik Andersen, 25 September 2000
174 * Better portability. Now should compile cleanly with libc5,
175 GNU libc 2.0 and 2.1, and various Linux kernels including
176 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
177 to make /proc/mounts behave included in the kernel-patches dir).
178 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
179 local files that matched tarball contents!!! Fix thanks
180 to Marius Groeger <mgroeger@sysgo.de>
181 * Fixed a nasty bug in tar when could mess up saved symlinks.
182 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
183 thanks to Daniel Quinlan <quinlan@transmeta.com>
184 * Updates to handle Linux 2.4.0 kernels (kludged around the
185 "none" entries in /proc/mounts, added a hack to make sysinfo
186 work with both old and new kernels).
187 * Fixed insmod module option parsing for options lacking an '='.
188 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
189 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
190 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
191 * Several fixes from Marius Groeger <mag@sysgo.de>
192 - Added support for "sh -c command args..."
193 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
194 - Added shell environment variable substitution
195 - Added the "read" shell builtin.
196 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
197 used to create an infinite loop: ls, cursor up, left, down.
198 * Added support for being a login shell, so things like
199 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
200 invoke the shell. Now you can use BusyBox as a login shell.
201 * ls.c now ignores '-g', since some ftp clients like that sort
202 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
203 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
204 it always sets the controlling terminal before running any programs
205 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
206 - Fixed tr so it recognizes standard escape sequences.
207 Merged common escape seq. code from tr and echo into utility.c.
208 - Major work in updating/cleaning up the docs, and getting the
209 new SGML based docs into shape.
211 - BusyBox should now poweroff when asked to do so.
212 - Fixed 'ln -n' and 'ln -s' so they both work properly.
213 * Reorganized signal names in kill.c for better architecture support
214 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
215 * In 0.43, backspace and delete worked properly, but with 0.45,
216 it just echoed a ^? for backspace, and ^H for control-h. This
217 was due to a broken macro in init.c, that is now fixed.
218 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
219 couldn't maintain it very well, so including it was not really
220 very appropriate. Those wanting an fdisk are invited to
221 grab a copy from util-linux.
222 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
223 then be loaded in by 'loadkmap' -- submitted by
224 Arne Bernin <arne@matrix.loopback.org>
225 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
226 * Brand, new versions of grep and sed which use libc regex routines,
227 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
228 "regexp.[ch]" files have been removed. Much help on these from
232 -Erik Andersen, 11 July 2000
236 * Now compiles vs libc5 (which can save lots of space for
238 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
239 help messages (i.e --help). Saves 17k over a full compile.
240 * Added cut and tr from minix, since due to the license change,
241 we can now use minix code. Minix tr saves 4k.
242 * insmod now works. It costs 29k, but imagine an initrd with a
243 staticly linked busybox containing only insmod and sh, a few /dev
244 entries, and a kernel module or two... It doesn't get smaller
245 then this folks (I pity the fool that writes insmod in asm ;-).
246 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
247 * Added a mini ar archive utility, especially written for BusyBox by
248 Glenn McGrath <bug1@netconnect.com.au>
249 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
250 * Added setkeycodes, for those that have wierd keyboard buttons.
251 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
252 <ams@trillian.itslinux.org> for contributing these.
253 * Added 'grep -v' option (inverted search) and updated
254 docs accordingly. -beppu
256 * Replaced the telnet implementation with one written by
257 Tomi Ollila <too@iki.fi> It works great and costs 3k.
258 * BusyBox sh (lash) now supports being used as a standalone shell. When
259 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
260 be invoked as shell internals. Best used when compiling staticly
262 * BusyBox sh (lash) internals now behave as expected wrt pipes
264 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
265 * Fixed update segfault
266 * Fixed mknod -- minor number was always 0
267 * Fixed tar option parsing, so both "tar xvf foo.tar" and
268 "tar -xvf foo.tar" now work (i.e. no "-" before options)
269 (this was very broken in 0.43).
270 * Several contributions from Randolph Chung <tausq@debian.org>.
271 * cp/mv now accepts the -f flag
272 * tail can now accept -<num> commands (e.g. -10) for better
273 compatibility with the standard tail command
274 * added a simple id implementation; doesn't support sup. groups yet
275 * logname used getlogin(3) which uses utmp. Now it doesn't.
276 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
277 * Add support for "noatime" and "nodiratime" mount flags to mount.
278 * Changed 'umount -f' to mean force, and actually use umount2.
279 * Changed 'umount -l' to mean "Do not free loop device".
280 * Fixed basename to support stripping of suffixes. Patch thanks
281 to xiong jianxin <jxiong@uiuc.edu>
282 * cp -fa now works as expected for symlinks (it didn't before)
283 * zcat now works (wasn't working since option parsing was broken)
284 * Renamed "mnc" to the more correct "nc" (for netcat).
285 * Makefile intelligence updates
286 * Changed the way init parses /etc/inittab entries to avoid problems
287 with commands that contain colons in them. Fix thanks to
288 Pavel Roskin <proski@gnu.org>
289 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
290 Fix thanks to Pavel Roskin <proski@gnu.org>
291 * Made "killall" complain (not error and exit) about processes that it
292 cannot find by name -- Pavel Roskin <proski@gnu.org>
293 * Fixed more and ps to have sensible terminal width defaults, thanks
295 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
296 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
297 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
298 * Fixed segfault caused by "touch -c"
299 * Fixed segfault caused by "rm -f"
300 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
301 and "--" support from Pavel Roskin.
302 * Fixed segfault caused by "cp -a -a" and similar abuses.
303 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
304 * "which" rewritten to use stat(). Fixes to improve its compatability
305 with traditional implementations -- Pavel Roskin.
306 * "mount" now reports errors from nfsmount() and assumes NFS mount
307 if ':' is present in the device name - Pavel Roskin
308 * Fixed exit status for killall - Pavel Roskin
309 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
310 * Fixed 'mount -a' so it works as expected.
311 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
312 * Implemented "ping -s", fixed error messages and argument parsing -
314 * Syslogd will not go to background if "-n" is given. Better help
315 and argument checking -- Pavel Roskin
316 * Fixed a small bug that could cause tar to emit warning messages
317 and not extract the first file in a directory in some cases
318 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
319 for helping track this one down.
321 * Fixed grep "Line too long" problem -- John Beppu
322 * Fixed 'grep -q -i B some_file' so it works
323 * math takes input from stdin if no args are given. -- John Beppu
324 * math was renamed to dc. Although it deviates from dc's behaviour,
325 this will probably be remedied in the future. -- John Beppu
328 -Erik Andersen, June 21, 2000
332 Previously, an erronous announcement of BusyBox 0.44 was made, so to
333 avoid possible confusion, we are skipping straight to 0.45, and calling
340 * Major update to the provided documentation.
341 * Busybox now includes a shell! It currently costs 7.5 k (plus an
342 additional 2.5 k if you compile in command line editing). Handles
343 job control, has the usual set of builtins, and does everything
344 except for handling programming statements (if, while, etc...)
345 * Busybox can now work perfectly when /proc is disabled, thereby
346 saving a bunch of memory (kernel /proc support is not thin). This
347 is done by making use of some nice kernel patches I wrote up to
348 support the features that busybox requires and that /proc usually
349 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
350 patch your kernel with the devps patch in the kernel-patches/
352 * Wrote basename, dirname, killall, and uptime.
353 * tar has been completely rewritten by me. Both tar creation and
354 extraction are now well behaved. Costs 7.6k with all optional
355 tar features enabled, and 5k for just tar extraction support.
356 * Added freeramdisk, which will free up all memory associated
357 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
358 and then adjusted a bit by me.
359 * Added tr from John Lombardo <john@deltanet.com>
360 * Added echo and test (from me).
361 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
362 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
363 * Several fixes from Pavel Roskin <proski@gnu.org>:
364 - When `tail' fails to open a file it now exits.
365 - When `syslogd' is given the `-n' option it should still use
366 fork() for running klogd.
367 * nslookup types are now changed to u_int32_t (instead of uint32_t)
368 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
369 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
370 to count hard-linked files more then once). Many thanks to
371 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
372 * Removed /proc dependancies for init and free (while maintaining
373 exactly the same functionality). /proc takes up 90k of kernel
374 space, so it is nice to avoid using it at all costs.
375 * init no longer tries to mount /proc (unless there is less the 1 meg
376 free). Use of /proc (or not) is policy that should be set up in
377 /etc/fstab (or in hardcoded scripts), not in init.
378 * Fixed rebooting when init runs as an initrd.
379 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
380 - update.c rewritten to look more like update-2.11
381 - moveed the inode hash out of du.c and into utility.c to make
382 it a common resource that can be used by other apps.
383 - cp_mv.c now checks inodes to see if a source and dest are
384 the same, and prints an error (instead of endlessly looping).
385 - mv now attempts to do a rename, and will fall back to doing
386 a copy only if the rename fails.
387 - Syslogd now supports multiple concurrent connections
388 * Several fixes from Pavel Roskin <proski@gnu.org>:
389 - Fixes to sort. Removed "-g", fixed and added "-r"
390 - Fixes to the makefile for handling "strip"
391 * An initial telnet implementation was added by
392 Randolph Chung <tausq@debian.org>.
393 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
394 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
395 to match the terminal (defaults to width=79 when this is off).
396 * ps now accepts (and ignores) all options except for "--help" (which
397 as would be expected displays help).
398 * Fixed mount'ing loop devices when the filesystem type was not
399 specified. It used to revert to non-loop after the first try.
400 * all mallocs now use xmalloc (and so are OOM error safe), and
401 the common error handling saves a few bytes. Thanks to
402 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
403 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
404 * Fix symlink following bug in chmod -R and friends.
405 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
406 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
415 * Fairly massive restructuring of umount.c to deal with remounting
416 busy devices read-only. Adds a -r option to control that; it is
417 optionally compiled in with BB_FEATURE_REMOUNT
418 * Added a bunch of functions to mtab.c to interact with the
419 {get,set,end}mntent interface; as it turns out, those functions do
420 not appear to be re-entrant, and that causes a lot of problems with
421 the way umount was originally written.
422 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
423 to be more consistent with sysvinit
424 * Changes to init.c to use the new -r option to umount. Also increased
425 the sleep time between the time the TERM and KILL signals are sent
430 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
431 extensively rewritten from the original cp.c.
432 * Fixed cp and mv so if the source and destination are a the
433 same directory it will print an error and continue.
434 * Also added a warning message to the `mv' usage string saying that
435 this is not GNU mv, and it will break hard links. cp also breaks
437 * ln.c: implemented `-n' switch, no-deref symlinks.
438 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
439 * name buffer overrun guards to prevent future crashes.
440 - Always check exit status.
441 - Purge all use of `creat()', replace with `open()'.
443 - recursiveAction was overriding the value of followLinks thus
445 - isDirectory now takes a followLinks boolean, updated all callers
446 - copyFile had the followLinks logic reversed.
447 * messages.c: New file. Put common error message strings all in
448 one place in an attempt to shrink the binary a little.
453 * changed fsck_minix.c to reduce its .bss size significantly
455 * Made tar creation support in busybox tar optional. You no longer
456 * _have_ to put a "-" in front of tar options. Tar could inadvertently
457 * change permissions and ownership on
458 certain directories pointed to by symlinks.
459 * Made grep and grep -h do the right thing wrt printing
460 the file name (it failed to print files names in many cases).
461 * Fix a namespace aliasing problem wereby if du was built in, the
462 symlink for both du and dutmp would be installed, or then rm was
463 built in, the symlinks for both rm and rmmod would be installed.
464 * Added a closelog() to init.c after loging -- fix thanks to
465 Taketoshi Sano <kgh12351@nifty.ne.jp>
466 * Rewrote and simplified logger. Added the "-t" option, and made it
467 behave itself a bit better.
468 * Optional support contributed by Ben Collins <bcollins@debian.org>
469 for the kernel init chroot patch by Werner Almesberger, which
470 allows init to chroot to a new device, and umount the old one.
471 * Fixed bug that wouldn't let one chown a symlink -- it would
472 always dereference before. -beppu
473 * Fixed a bug where init could have reference already freed memory.
474 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
475 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
476 * Added (and documented) "-n" option for head
477 * Cleanup for a number of usage messages -- also
478 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
479 * Cosmetic fix to busybox.c (Don't print a comma at the
480 end of line if there are no more application names).
481 * Fixed a stupid bug in "head" option handling ("head -n"
483 * Moved commonly used functions "xmalloc()" and "exit()"
484 to utility.c (with proper #ifdef's).
485 * Created a tiny tail implementation, removing -c, -q, -v, and making
486 tail -f work only with a single file. This reduced tail from 6k to
487 2.4k. The bigger/more featured tail can still be had by disabling
488 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
489 * Ping now falls back to doing the right thing if /etc/protocols
491 * Fixed mount and umount. Previously they could leak loop device
492 allocations, causing the system to quickly run out. Fix for umount
493 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
494 * ls formatting on eight charactor user names fixed by
495 Randolph Chung <tausq@debian.org>.
496 * cp could, when copying symlinks, change permissions of the
497 files pointed to by the symlinks.
498 * Several fixes from Pavel Roskin <proski@gnu.org>:
499 - `chown' with 1 argument displayed the error incorrectly
500 - `fdflush', `length' and `printf' crashed if run without arguments
501 - `fdflush' tried to flush itself using *argv
502 - added "skip" and "seek" to dd.
503 - ls no longer messus up output when combining files and
504 directories on the command line
505 * swapoff -a was not working. Now it is.
506 * init did not cleanly unmount filesystems on reboot. Now it does.
507 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
509 * Some architectures (PowerPc) assume chars are unsigned, so they could
510 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
511 * Began converting error handling to use some common routines
513 * syslogd now has better message handling and ignores SIGHUP.
514 * install.sh had a bug preventing installation to the specified
515 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
516 * You can now spefify alternative strip commands -- change
517 also from Gilbert Coville.
523 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
524 by Edward Betts <edward@debian.org>
525 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
526 type commands (file in a directory to another directory) from
528 * Fixed a logger bug that caused garbage to be written to the syslog
529 (unless you used busybox syslog, which hid the bug). Thanks to
530 Alex Holden <alex@linuxhacker.org> for the fix.
531 * /bin/true and /bin/false were echoing a blank line when run.
533 * mkdir -p would print an error when asked to mkdir an existing dir
534 with no interveining subdirectories.
535 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
536 * and support in umount for loop
537 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
538 <bcollins@debian.org>
539 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
540 * fullWrite() not only if BB_TAR is defined, but also
541 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
542 * add some compiler optimizations to further reduce executable size
543 (as a side note, on my machines the largest code is generated
544 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
546 * Compile now won't fail if busybox.def.h defines
547 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
548 referenced, but not compiled)
549 * Fixed a bug in setting TERM for serial console support. TERM now
550 defaults to "ansi" for serial consoles.
551 * Fixed a bug in handling the CONSOLE env. variable for serial
554 -Erik Andersen, Jan 15, 2000
557 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
558 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
559 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
560 for loading application character maps for Unicode fonts.
561 * Major init re-work. init now supports inittab (slightly different
562 but similar to sysvinit), allowing me to get all the policy out of
563 init and into the conf file. It works just fine without inittab
564 being present, but if you dont like the default behavior you can
565 now do something about it. Init is much cleaner as a result.
566 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
567 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
568 * failure of 'logger -p'. -erik Added the -s option to du -beppu
569 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
570 with the 2.0.x Linux kernel.
571 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
573 * Grep -i previously failed on UPPER CASE patterns due to a silly
574 regexp implementation bug that is now fixed.
575 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
576 * Fixed a bug where tar would not set the user and group on device
578 * Fixed a bug where tar would not restore the time to files. Fixed a
579 * major security problem with tar -- it changed ownership
580 of any file pointed to by a symlink to 777 (like say libc....)
582 * cp and mv were very broken when moving directories. I have rewritten
583 them so they should now work as expected.
584 * sed now supports addresses (numeric or regexp, with negation) and
585 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
586 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
587 * Some cosmetic fixes to ls output formatting to make it behave more
589 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
590 * <fwv@myrtle.lahn.de>:
591 - Added gunzip -t, removed gunzip.c dead code,
592 - fixed several typos
593 - Glibc 2.0.7 and libc5 compile fixes
594 * Fixed a bug where 'mknod --help' would segfault.
597 -Erik Andersen, Jan 07, 2000
600 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
601 <tausq@debian.org>. 3 items off the TODO list!
602 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
603 * tail from GNU textutils-1.19, but adjusted
604 to suit my evil purposes. Costs 6k. I'll make it smaller
606 * on reboot, init called 'umount -a -n', which caused errors
607 when BB_MTAB was not enabled. Changed to 'umount -a', which does
609 * init will now try to run /sbin/getty if it is present (for easy
610 integration with the about-to-be-released tinylogin.)
611 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
612 * -l' was failing on long directories, since my_getid was leaking
613 one file descriptor per file. Oops.
614 * Fixed rebooting from init. I'd accidently left some debugging code
616 which blocked reboots.
617 * Fixed reboot, halt (and added poweroff) such that they handle it when
618 init is not at PID 1 (like when running in an initrd).
619 * Added a prelinary du implementation. Some parameter parsing
620 stuff still needs to be added. -beppu (John Beppu
622 * Implemented tee. -beppu Implemented head. -beppu
624 -Erik Andersen, Dec 10, 1999
627 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
629 * df will not exit on error, but will stat all mounted filesystems.
630 * Fixed tar so uid/gid/permissions on extracted tarballs will be
632 * Fixed find -name so it properly uses shell wildcard patterns
633 (i.e. `*', `?', and `[]') instead of regular expressions, which
634 was causing some confusing and unexpected behavior.
635 * Added klogd to syslogd, so now the log will contain both system and
637 * syslogd now creates the /dev/log socket to make sure it is there, and
638 is actually a socket with the right permissions.
639 * I've taken a first step to making busybox not need the /proc
640 filesystem. Most apps don't need it. Those that _require_ it,
641 will complain if you enable them when you disable
642 BB_FEATURE_USE_PROCFS.
644 -Erik Andersen, Dec 5, 1999
647 * Wrote a micro syslogd, and a logger util (to log things to the syslog
648 from the command line or scripts) With both compiled in, costs 4k.
649 * Fixed 'make install' so symlinks are installed in their proper
650 * locations. Changed the build system slightly so that features can
652 or disabled from the busybox.defs.h header file, without trying to
653 compile in a source file named after that featue (unless that file
655 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
656 * -r' both work. dd now properly handles input beyond 1 block from
657 * stdin. Fixed a bug where tar unpacked everything a directories.
659 from createPath into mkdir where it belonged, thereby making tar
661 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
663 last file in the list.
664 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
666 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
667 are presented properly.
671 -Erik Andersen, Nov 25, 1999
674 * fixed dd so it properly defaults to stdin and stdout when no
675 if= and of= are set (fix thanks to Eric Delaunay).
676 * Don't try to close the file descriptor of a pipein tar. (fix also
679 * Made createPath be quiet (again thanks to Eric Delaunay). If
680 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
681 command you define it as will be run if the init script exits.
682 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
683 * NFS support added to mount by Eric Delaunay. It costs 10k when
685 in, but that is still a big win for those that use NFS.
686 * Made 'rm -f' be silent for non-existant files (thanks to Eric
687 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
689 and acts as god intended gunzip and zcat to act. They answer
690 --help and obey the '-c' flag.
691 * Fixed a bug in mv which caused it to not move files when the
694 * Fixed a decimal-instead-of-octal bug causing mkdir to make
696 with very wrong permissions.
697 * chmod would overwrite file permissions instead of modifying them.
698 Now it properly modifies permissions.
699 * Init now sends warnings destined for the console to /dev/console to
701 they show up on whatever the active console it. Otherwise
702 important messages (for example that the system is rebooting) were
703 not seen when switched to a different VT.
705 -Erik Andersen, Nov 17, 1999
708 * gzip now obeys the principle of least surprise and acts like god
710 (i.e. it accepts a file name, answers --help, and obeys the '-c'
711 flag and only then outputs to stdout).
712 * Fixed more.c to compile autowidth on sparc and set initial winsize
713 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
715 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
716 * tar now accepts --help chmod, chown, and chgrp usage now works
717 * General usage (i.e. --help) cleanups for most apps umount now parses
718 * options correctly tar can now unpack tarballs containing device
720 sockets, and fifos (though it can't pack them up) thanks to Matt
721 Porter. Creating archives containing these is still left to the
723 * fixed up the license in more.c to properly point to Bruce Perens.
725 -Erik Andersen, Nov 11, 1999
728 * ls -l now displays link names outside the current directory,
729 Patch thanks to Eric Delaunay
730 * init now properly handles sparc serial consoles and does a
731 better job of finding the real console device rather than using
732 /dev/console which doesn't support job control. Patch also thanks
734 * more started to read from stdin after the last file was finished, and
735 options were not parsed correctly (fix thanks to Eric Delaunay).
736 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
737 * rm wouldn't remove a symlink unless the symlink was valid. This was
738 a side effect of the busybox 0.32 recursiveAction() fix. Things
739 should now work correctly.
740 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
741 * it does. sed was appending a \n to the end of lines with
743 Now it doesn't do that.
744 * ls -l now bypasses libc6 nss when displaying user/group names.
745 Now uses my_getpwuid and my_getgrgid.
747 -Erik Andersen, Nov 8, 1999
750 * Fixed a bug where init could hang instead of rebooting.
751 * Removed some debugging noise from init.c
752 * Fixed ln so it works now (it was very broken).
753 * Fixed df so it won't segfault when there is no /etc/fstab,
754 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
755 is not installed (since they cannot fixup "/dev/root" to
756 state the real root device name)
757 * merged some redundant code from mtab.c/df.c into utility.c
759 -Erik Andersen, Nov 5, 1999
762 * More changes -- many thanks to Lineo for paying me to work on
763 busybox. If you have any problems please let me know ASAP at
764 andersen@lineo.com or andersee@debian.org
765 * usage() now prints the BusyBox version. This will help folks
766 realize that they are not in Kansas anymore.
767 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
768 * arguments. Now it doesn't do that. kill wasn't properly accepting
769 * signal names. It does now. Added new apps chvt and deallocvt (I
770 * should probably add open) Major rewrite of init.c. Code is now
771 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
772 * with full regular expressions!). Fixed a stupid seg-fault in sync
773 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
774 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
775 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
776 * cost of ~1.5k and the need for a rw /etc)
777 folks to use a real /etc/mtab file instead of a symlink to
778 /proc/mounts. mount, and umount will add/remove entries and df
779 will now use /etc/mtab if BB_MTAB is defined.
780 * Fixed a nice bug in recursiveAction() which caused it to infinitely
781 hunt through /proc/../fd/* creating new file descriptors if it
782 followed the /dev/fd link over to /proc. recursiveAction() now
783 lstat's the file when followLinks==FALSE so it won't follow links
784 as the name suggests. Fix thanks to Matt Porter
788 -Erik Andersen, Nov 4, 1999
791 * I added a changelog for version 0.30. adjusted find internals to
792 * make it smaller, and removed
794 * Fixed a segfault in ps when /etc/passwd or /etc/group
795 are absent. Now will warn you and carry on.
796 * Added in optional _real_ regular expression support (to be
797 the basis for a future sed utility). When compiled in it adds
798 3.9k, but makes grep much more capable.
799 * Checked out using nftw(3) for recursive stuff, but unfortunatly
800 it wasn't supported before GNU libc 2.1, and some folks use glibc
801 2.0.7 since it is much smaller than that latest and greatest.
803 -Erik Andersen, Oct 21, 1999
806 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
807 paying me to make these updates. If you have any problems with busybox,
808 or notice any bugs -- please let me know so I can fix it. These
812 * busybox can now invoke apps in two ways: via symlinks to the
813 busybox binary, and as 'busybox [function] [arguments]...'
814 * When invoked as busybox, the list of currently compiled in
815 functions is printed out (no this is not bloat -- the list has
816 to be there anyway to map invocation name to function).
817 * busybox no longer parses command lines for apps or displays their
818 usage info. Each app gets to handle (or not handle) this for
820 * Eliminated monadic, dyadic, descend, block_device, and
821 postprocess. It was cumbersome to have so many programs
822 cobbled together in this way. Without them, the app is much
824 * All shared code now lives in utility.c, and is properly
825 ifdef'ed to be only included for those apps requiring it.
826 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
827 so now each app has the function prototype of (da-dum): extern
828 int foo_main(int argc, char** argv); which speeds integration
830 * Adjusted the Makefile to make it easier to
831 {en|dis}able debugging.
832 * Changed default compiler optimization to -Os
833 (optimize for smaller binaries).
836 * To cope with the new app function prototype and the removal of
837 monadic, dyadic, etc, the following apps were re-written:
838 * cat - Works same as always. chgrp, chmod, chown -
839 * rewrite. Combined into a single
840 source file. Absorbed patches from Enrique Zanardi
841 <ezanard@debian.org> that removes the dependency on
842 libc6 libnss* libraries.
843 * cp - Can now do 'cp -a' can can copy devices,
844 pipes, symlinks, as well as recursive or non-recursive
846 * fdflush - adjusted to remove dependancy on struct
847 * FileInfo. find - Now includes some basic regexp matching
848 which will be the basic of a future mini-sed.
849 * ln - Same functionality. mkdir - Added -p flag to
850 * feature set. mv - rewrite. rm - Added -f flag to
851 * feature set. rmdir - Same functionality. swapon,
852 * swapoff - Combined into a single binary. No longer
853 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
855 * touch - Same functionality. date - adjusted with a patch
856 * from Matthew Grant <grantma@anathoth.gen.nz>
857 to accomodate glibc timezone support. I then ripped out GNU
859 * mkswap -- new version merged from util-linux. Can now make
861 * Replaced the old and star, unstar, and tarcat with the tar
862 implementation from sash. Now tar behaves as god intended it
863 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
864 * dd -- rewritten. Can with with files, stdin, stdout. Added the
865 * following new apps: loadfont -- added from debian boot floppies
866 * chroot -- added based on a patch from Paolo Molaro
867 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
868 * simple strings ps -- I just wrote it. Has _no_ options at all,
869 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
871 internationalization and such to make them smaller.
872 * sfdisk -- Added from util-linux (minus
873 * internationalization and such). Probably some other
874 * changes that I forgot to document...
876 -Erik Andersen, Oct 20, 1999
879 This version was a messy pre-alpha. stay away or it will bite you.
880 -Erik Andersen, Sep 24, 1999
883 mini-netcat (mnc) rewritten.
886 Mount now supports -a, and -t auto.
887 Mount now updates mtab correctly for 'ro'.
888 More checks screen rows size, outputs bytes percentage.
889 Printf added as module.
891 Touch now creates files. -c option for no create.
