3 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
5 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
6 * added 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
7 * 'make install' now creates relative symlinks, and added a new
8 'make install-hardlinks' target to (tada) install hardlinks.
9 * syslogd can now log messages to a remote host -- patch thanks
10 to Gyepi Sam <gyepi@praxis-sw.com>
11 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
12 It now weighs only 2.25k (3k when full featured). The code is
13 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
14 * Add optional ls file sorting, thanks to a patch from
15 Sterling Huxley <sterling@europa.com>
16 * lsmod now uses the query_module syscall, rather then /proc
17 * Added 'rdate' command from Sterling Huxley <sterling@europa.com>
18 * Added 'wget' command, contributed by Chip Rosenthal <chip@unicom.com>,
19 <crosenth@covad.com> and Covad Communications
20 * Added 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
21 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
22 wouldn't work (since it thought -r was an option). Doh!
23 * Added dos2unix, unix2dos, and unrpm.c thanks to robotti@metconnect.com.
32 * Better portability. Now should compile cleanly with libc5,
33 GNU libc 2.0 and 2.1, and various Linux kernels including
34 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
35 to make /proc/mounts behave included in the kernel-patches dir).
36 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
37 local files that matched tarball contents!!! Fix thanks
38 to Marius Groeger <mgroeger@sysgo.de>
39 * Fixed a nasty bug in tar when could mess up saved symlinks.
40 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
41 thanks to Daniel Quinlan <quinlan@transmeta.com>
42 * Updates to handle Linux 2.4.0 kernels (kludged around the
43 "none" entries in /proc/mounts, added a hack to make sysinfo
44 work with both old and new kernels).
45 * Fixed insmod module option parsing for options lacking an '='.
46 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
47 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
48 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
49 * Several fixes from Marius Groeger <mag@sysgo.de>
50 - Added support for "sh -c command args..."
51 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
52 - Added shell environment variable substitution
53 - Added the "read" shell builtin.
54 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
55 used to create an infinite loop: ls, cursor up, left, down.
56 * Added support for being a login shell, so things like
57 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
58 invoke the shell. Now you can use BusyBox as a login shell.
59 * ls.c now ignores '-g', since some ftp clients like that sort
60 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
61 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
62 it always sets the controlling terminal before running any programs
63 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
64 - Fixed tr so it recognizes standard escape sequences.
65 Merged common escape seq. code from tr and echo into utility.c.
66 - Major work in updating/cleaning up the docs, and getting the
67 new SGML based docs into shape.
69 - BusyBox should now poweroff when asked to do so.
70 - Fixed 'ln -n' and 'ln -s' so they both work properly.
71 * Reorganized signal names in kill.c for better architecture support
72 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
73 * In 0.43, backspace and delete worked properly, but with 0.45,
74 it just echoed a ^? for backspace, and ^H for control-h. This
75 was due to a broken macro in init.c, that is now fixed.
76 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
77 couldn't maintain it very well, so including it was not really
78 very appropriate. Those wanting an fdisk are invited to
79 grab a copy from util-linux.
80 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
81 then be loaded in by 'loadkmap' -- submitted by
82 Arne Bernin <arne@matrix.loopback.org>
83 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
84 * Brand, new versions of grep and sed which use libc regex routines,
85 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
86 "regexp.[ch]" files have been removed. Much help on these from
94 * Now compiles vs libc5 (which can save lots of space for
96 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
97 help messages (i.e --help). Saves 17k over a full compile.
98 * Added cut and tr from minix, since due to the license change,
99 we can now use minix code. Minix tr saves 4k.
100 * insmod now works. It costs 29k, but imagine an initrd with a
101 staticly linked busybox containing only insmod and sh, a few /dev
102 entries, and a kernel module or two... It doesn't get smaller
103 then this folks (I pity the fool that writes insmod in asm ;-).
104 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
105 * Added a mini ar archive utility, especially written for BusyBox by
106 Glenn McGrath <bug1@netconnect.com.au>
107 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
108 * Added setkeycodes, for those that have wierd keyboard buttons.
109 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
110 <ams@trillian.itslinux.org> for contributing these.
111 * Added 'grep -v' option (inverted search) and updated
112 docs accordingly. -beppu
114 * Replaced the telnet implementation with one written by
115 Tomi Ollila <too@iki.fi> It works great and costs 3k.
116 * BusyBox sh (lash) now supports being used as a standalone shell. When
117 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
118 be invoked as shell internals. Best used when compiling staticly
120 * BusyBox sh (lash) internals now behave as expected wrt pipes
122 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
123 * Fixed update segfault
124 * Fixed mknod -- minor number was always 0
125 * Fixed tar option parsing, so both "tar xvf foo.tar" and
126 "tar -xvf foo.tar" now work (i.e. no "-" before options)
127 (this was very broken in 0.43).
128 * Several contributions from Randolph Chung <tausq@debian.org>.
129 * cp/mv now accepts the -f flag
130 * tail can now accept -<num> commands (e.g. -10) for better
131 compatibility with the standard tail command
132 * added a simple id implementation; doesn't support sup. groups yet
133 * logname used getlogin(3) which uses utmp. Now it doesn't.
134 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
135 * Add support for "noatime" and "nodiratime" mount flags to mount.
136 * Changed 'umount -f' to mean force, and actually use umount2.
137 * Changed 'umount -l' to mean "Do not free loop device".
138 * Fixed basename to support stripping of suffixes. Patch thanks
139 to xiong jianxin <jxiong@uiuc.edu>
140 * cp -fa now works as expected for symlinks (it didn't before)
141 * zcat now works (wasn't working since option parsing was broken)
142 * Renamed "mnc" to the more correct "nc" (for netcat).
143 * Makefile intelligence updates
144 * Changed the way init parses /etc/inittab entries to avoid problems
145 with commands that contain colons in them. Fix thanks to
146 Pavel Roskin <proski@gnu.org>
147 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
148 Fix thanks to Pavel Roskin <proski@gnu.org>
149 * Made "killall" complain (not error and exit) about processes that it
150 cannot find by name -- Pavel Roskin <proski@gnu.org>
151 * Fixed more and ps to have sensible terminal width defaults, thanks
153 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
154 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
155 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
156 * Fixed segfault caused by "touch -c"
157 * Fixed segfault caused by "rm -f"
158 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
159 and "--" support from Pavel Roskin.
160 * Fixed segfault caused by "cp -a -a" and similar abuses.
161 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
162 * "which" rewritten to use stat(). Fixes to improve its compatability
163 with traditional implementations -- Pavel Roskin.
164 * "mount" now reports errors from nfsmount() and assumes NFS mount
165 if ':' is present in the device name - Pavel Roskin
166 * Fixed exit status for killall - Pavel Roskin
167 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
168 * Fixed 'mount -a' so it works as expected.
169 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
170 * Implemented "ping -s", fixed error messages and argument parsing -
172 * Syslogd will not go to background if "-n" is given. Better help
173 and argument checking -- Pavel Roskin
174 * Fixed a small bug that could cause tar to emit warning messages
175 and not extract the first file in a directory in some cases
176 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
177 for helping track this one down.
179 * Fixed grep "Line too long" problem -- John Beppu
180 * Fixed 'grep -q -i B some_file' so it works
181 * math takes input from stdin if no args are given. -- John Beppu
182 * math was renamed to dc. Although it deviates from dc's behaviour,
183 this will probably be remedied in the future. -- John Beppu
186 -Erik Andersen, June 21, 2000
190 Previously, an erronous announcement of BusyBox 0.44 was made, so to
191 avoid possible confusion, we are skipping straight to 0.45, and calling
198 * Major update to the provided documentation.
199 * Busybox now includes a shell! It currently costs 7.5 k (plus an
200 additional 2.5 k if you compile in command line editing). Handles
201 job control, has the usual set of builtins, and does everything
202 except for handling programming statements (if, while, etc...)
203 * Busybox can now work perfectly when /proc is disabled, thereby
204 saving a bunch of memory (kernel /proc support is not thin). This
205 is done by making use of some nice kernel patches I wrote up to
206 support the features that busybox requires and that /proc usually
207 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
208 patch your kernel with the devps patch in the kernel-patches/
210 * Wrote basename, dirname, killall, and uptime.
211 * tar has been completely rewritten by me. Both tar creation and
212 extraction are now well behaved. Costs 7.6k with all optional
213 tar features enabled, and 5k for just tar extraction support.
214 * Added freeramdisk, which will free up all memory associated
215 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
216 and then adjusted a bit by me.
217 * Added tr from John Lombardo <john@deltanet.com>
218 * Added echo and test (from me).
219 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
220 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
221 * Several fixes from Pavel Roskin <proski@gnu.org>:
222 - When `tail' fails to open a file it now exits.
223 - When `syslogd' is given the `-n' option it should still use
224 fork() for running klogd.
225 * nslookup types are now changed to u_int32_t (instead of uint32_t)
226 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
227 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
228 to count hard-linked files more then once). Many thanks to
229 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
230 * Removed /proc dependancies for init and free (while maintaining
231 exactly the same functionality). /proc takes up 90k of kernel
232 space, so it is nice to avoid using it at all costs.
233 * init no longer tries to mount /proc (unless there is less the 1 meg
234 free). Use of /proc (or not) is policy that should be set up in
235 /etc/fstab (or in hardcoded scripts), not in init.
236 * Fixed rebooting when init runs as an initrd.
237 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
238 - update.c rewritten to look more like update-2.11
239 - moveed the inode hash out of du.c and into utility.c to make
240 it a common resource that can be used by other apps.
241 - cp_mv.c now checks inodes to see if a source and dest are
242 the same, and prints an error (instead of endlessly looping).
243 - mv now attempts to do a rename, and will fall back to doing
244 a copy only if the rename fails.
245 - Syslogd now supports multiple concurrent connections
246 * Several fixes from Pavel Roskin <proski@gnu.org>:
247 - Fixes to sort. Removed "-g", fixed and added "-r"
248 - Fixes to the makefile for handling "strip"
249 * An initial telnet implementation was added by
250 Randolph Chung <tausq@debian.org>.
251 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
252 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
253 to match the terminal (defaults to width=79 when this is off).
254 * ps now accepts (and ignores) all options except for "--help" (which
255 as would be expected displays help).
256 * Fixed mount'ing loop devices when the filesystem type was not
257 specified. It used to revert to non-loop after the first try.
258 * all mallocs now use xmalloc (and so are OOM error safe), and
259 the common error handling saves a few bytes. Thanks to
260 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
261 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
262 * Fix symlink following bug in chmod -R and friends.
263 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
264 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
273 * Fairly massive restructuring of umount.c to deal with remounting
274 busy devices read-only. Adds a -r option to control that; it is
275 optionally compiled in with BB_FEATURE_REMOUNT
276 * Added a bunch of functions to mtab.c to interact with the
277 {get,set,end}mntent interface; as it turns out, those functions do
278 not appear to be re-entrant, and that causes a lot of problems with
279 the way umount was originally written.
280 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
281 to be more consistent with sysvinit
282 * Changes to init.c to use the new -r option to umount. Also increased
283 the sleep time between the time the TERM and KILL signals are sent
288 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
289 extensively rewritten from the original cp.c.
290 * Fixed cp and mv so if the source and destination are a the
291 same directory it will print an error and continue.
292 * Also added a warning message to the `mv' usage string saying that
293 this is not GNU mv, and it will break hard links. cp also breaks
295 * ln.c: implemented `-n' switch, no-deref symlinks.
296 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
297 * name buffer overrun guards to prevent future crashes.
298 - Always check exit status.
299 - Purge all use of `creat()', replace with `open()'.
301 - recursiveAction was overriding the value of followLinks thus
303 - isDirectory now takes a followLinks boolean, updated all callers
304 - copyFile had the followLinks logic reversed.
305 * messages.c: New file. Put common error message strings all in
306 one place in an attempt to shrink the binary a little.
311 * changed fsck_minix.c to reduce its .bss size significantly
313 * Made tar creation support in busybox tar optional. You no longer
314 * _have_ to put a "-" in front of tar options. Tar could inadvertently
315 * change permissions and ownership on
316 certain directories pointed to by symlinks.
317 * Made grep and grep -h do the right thing wrt printing
318 the file name (it failed to print files names in many cases).
319 * Fix a namespace aliasing problem wereby if du was built in, the
320 symlink for both du and dutmp would be installed, or then rm was
321 built in, the symlinks for both rm and rmmod would be installed.
322 * Added a closelog() to init.c after loging -- fix thanks to
323 Taketoshi Sano <kgh12351@nifty.ne.jp>
324 * Rewrote and simplified logger. Added the "-t" option, and made it
325 behave itself a bit better.
326 * Optional support contributed by Ben Collins <bcollins@debian.org>
327 for the kernel init chroot patch by Werner Almesberger, which
328 allows init to chroot to a new device, and umount the old one.
329 * Fixed bug that wouldn't let one chown a symlink -- it would
330 always dereference before. -beppu
331 * Fixed a bug where init could have reference already freed memory.
332 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
333 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
334 * Added (and documented) "-n" option for head
335 * Cleanup for a number of usage messages -- also
336 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
337 * Cosmetic fix to busybox.c (Don't print a comma at the
338 end of line if there are no more application names).
339 * Fixed a stupid bug in "head" option handling ("head -n"
341 * Moved commonly used functions "xmalloc()" and "exit()"
342 to utility.c (with proper #ifdef's).
343 * Created a tiny tail implementation, removing -c, -q, -v, and making
344 tail -f work only with a single file. This reduced tail from 6k to
345 2.4k. The bigger/more featured tail can still be had by disabling
346 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
347 * Ping now falls back to doing the right thing if /etc/protocols
349 * Fixed mount and umount. Previously they could leak loop device
350 allocations, causing the system to quickly run out. Fix for umount
351 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
352 * ls formatting on eight charactor user names fixed by
353 Randolph Chung <tausq@debian.org>.
354 * cp could, when copying symlinks, change permissions of the
355 files pointed to by the symlinks.
356 * Several fixes from Pavel Roskin <proski@gnu.org>:
357 - `chown' with 1 argument displayed the error incorrectly
358 - `fdflush', `length' and `printf' crashed if run without arguments
359 - `fdflush' tried to flush itself using *argv
360 - added "skip" and "seek" to dd.
361 - ls no longer messus up output when combining files and
362 directories on the command line
363 * swapoff -a was not working. Now it is.
364 * init did not cleanly unmount filesystems on reboot. Now it does.
365 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
367 * Some architectures (PowerPc) assume chars are unsigned, so they could
368 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
369 * Began converting error handling to use some common routines
371 * syslogd now has better message handling and ignores SIGHUP.
372 * install.sh had a bug preventing installation to the specified
373 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
374 * You can now spefify alternative strip commands -- change
375 also from Gilbert Coville.
381 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
382 by Edward Betts <edward@debian.org>
383 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
384 type commands (file in a directory to another directory) from
386 * Fixed a logger bug that caused garbage to be written to the syslog
387 (unless you used busybox syslog, which hid the bug). Thanks to
388 Alex Holden <alex@linuxhacker.org> for the fix.
389 * /bin/true and /bin/false were echoing a blank line when run.
391 * mkdir -p would print an error when asked to mkdir an existing dir
392 with no interveining subdirectories.
393 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
394 * and support in umount for loop
395 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
396 <bcollins@debian.org>
397 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
398 * fullWrite() not only if BB_TAR is defined, but also
399 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
400 * add some compiler optimizations to further reduce executable size
401 (as a side note, on my machines the largest code is generated
402 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
404 * Compile now won't fail if busybox.def.h defines
405 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
406 referenced, but not compiled)
407 * Fixed a bug in setting TERM for serial console support. TERM now
408 defaults to "ansi" for serial consoles.
409 * Fixed a bug in handling the CONSOLE env. variable for serial
412 -Erik Andersen, Jan 15, 2000
415 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
416 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
417 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
418 for loading application character maps for Unicode fonts.
419 * Major init re-work. init now supports inittab (slightly different
420 but similar to sysvinit), allowing me to get all the policy out of
421 init and into the conf file. It works just fine without inittab
422 being present, but if you dont like the defautl behavior you can
423 now do something about it. Init is much cleaner as a result.
424 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
425 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
426 * failure of 'logger -p'. -erik Added the -s option to du -beppu
427 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
428 with the 2.0.x Linux kernel.
429 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
431 * Grep -i previously failed on UPPER CASE patterns due to a silly
432 regexp implementation bug that is now fixed.
433 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
434 * Fixed a bug where tar would not set the user and group on device
436 * Fixed a bug where tar would not restore the time to files. Fixed a
437 * major security problem with tar -- it changed ownership
438 of any file pointed to by a symlink to 777 (like say libc....)
440 * cp and mv were very broken when moving directories. I have rewritten
441 them so they should now work as expected.
442 * sed now supports addresses (numeric or regexp, with negation) and
443 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
444 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
445 * Some cosmetic fixes to ls output formatting to make it behave more
447 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
448 * <fwv@myrtle.lahn.de>:
449 - Added gunzip -t, removed gunzip.c dead code,
450 - fixed several typos
451 - Glibc 2.0.7 and libc5 compile fixes
452 * Fixed a bug where 'mknod --help' would segfault.
455 -Erik Andersen, Jan 07, 2000
458 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
459 <tausq@debian.org>. 3 items off the TODO list!
460 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
461 * tail from GNU textutils-1.19, but adjusted
462 to suit my evil purposes. Costs 6k. I'll make it smaller
464 * on reboot, init called 'umount -a -n', which caused errors
465 when BB_MTAB was not enabled. Changed to 'umount -a', which does
467 * init will now try to run /sbin/getty if it is present (for easy
468 integration with the about-to-be-released tinylogin.)
469 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
470 * -l' was failing on long directories, since my_getid was leaking
471 one file descriptor per file. Oops.
472 * Fixed rebooting from init. I'd accidently left some debugging code
474 which blocked reboots.
475 * Fixed reboot, halt (and added poweroff) such that they handle it when
476 init is not at PID 1 (like when running in an initrd).
477 * Added a prelinary du implementation. Some parameter parsing
478 stuff still needs to be added. -beppu (John Beppu
480 * Implemented tee. -beppu Implemented head. -beppu
482 -Erik Andersen, Dec 10, 1999
485 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
487 * df will not exit on error, but will stat all mounted filesystems.
488 * Fixed tar so uid/gid/permissions on extracted tarballs will be
490 * Fixed find -name so it properly uses shell wildcard patterns
491 (i.e. `*', `?', and `[]') instead of regular expressions, which
492 was causing some confusing and unexpected behavior.
493 * Added klogd to syslogd, so now the log will contain both system and
495 * syslogd now creates the /dev/log socket to make sure it is there, and
496 is actually a socket with the right permissions.
497 * I've taken a first step to making busybox not need the /proc
498 filesystem. Most apps don't need it. Those that _require_ it,
499 will complain if you enable them when you disable
500 BB_FEATURE_USE_PROCFS.
502 -Erik Andersen, Dec 5, 1999
505 * Wrote a micro syslogd, and a logger util (to log things to the syslog
506 from the command line or scripts) With both compiled in, costs 4k.
507 * Fixed 'make install' so symlinks are installed in their proper
508 * locations. Changed the build system slightly so that features can
510 or disabled from the busybox.defs.h header file, without trying to
511 compile in a source file named after that featue (unless that file
513 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
514 * -r' both work. dd now properly handles input beyond 1 block from
515 * stdin. Fixed a bug where tar unpacked everything a directories.
517 from createPath into mkdir where it belonged, thereby making tar
519 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
521 last file in the list.
522 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
524 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
525 are presented properly.
529 -Erik Andersen, Nov 25, 1999
532 * fixed dd so it properly defaults to stdin and stdout when no
533 if= and of= are set (fix thanks to Eric Delaunay).
534 * Don't try to close the file descriptor of a pipein tar. (fix also
537 * Made createPath be quiet (again thanks to Eric Delaunay). If
538 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
539 command you define it as will be run if the init script exits.
540 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
541 * NFS support added to mount by Eric Delaunay. It costs 10k when
543 in, but that is still a big win for those that use NFS.
544 * Made 'rm -f' be silent for non-existant files (thanks to Eric
545 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
547 and acts as god intended gunzip and zcat to act. They answer
548 --help and obey the '-c' flag.
549 * Fixed a bug in mv which caused it to not move files when the
552 * Fixed a decimal-instead-of-octal bug causing mkdir to make
554 with very wrong permissions.
555 * chmod would overwrite file permissions instead of modifying them.
556 Now it properly modifies permissions.
557 * Init now sends warnings destined for the console to /dev/console to
559 they show up on whatever the active console it. Otherwise
560 important messages (for example that the system is rebooting) were
561 not seen when switched to a different VT.
563 -Erik Andersen, Nov 17, 1999
566 * gzip now obeys the principle of least surprise and acts like god
568 (i.e. it accepts a file name, answers --help, and obeys the '-c'
569 flag and only then outputs to stdout).
570 * Fixed more.c to compile autowidth on sparc and set initial winsize
571 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
573 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
574 * tar now accepts --help chmod, chown, and chgrp usage now works
575 * General usage (i.e. --help) cleanups for most apps umount now parses
576 * options correctly tar can now unpack tarballs containing device
578 sockets, and fifos (though it can't pack them up) thanks to Matt
579 Porter. Creating archives containing these is still left to the
581 * fixed up the license in more.c to properly point to Bruce Perens.
583 -Erik Andersen, Nov 11, 1999
586 * ls -l now displays link names outside the current directory,
587 Patch thanks to Eric Delaunay
588 * init now properly handles sparc serial consoles and does a
589 better job of finding the real console device rather than using
590 /dev/console which doesn't support job control. Patch also thanks
592 * more started to read from stdin after the last file was finished, and
593 options were not parsed correctly (fix thanks to Eric Delaunay).
594 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
595 * rm wouldn't remove a symlink unless the symlink was valid. This was
596 a side effect of the busybox 0.32 recursiveAction() fix. Things
597 should now work correctly.
598 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
599 * it does. sed was appending a \n to the end of lines with
601 Now it doesn't do that.
602 * ls -l now bypasses libc6 nss when displaying user/group names.
603 Now uses my_getpwuid and my_getgrgid.
605 -Erik Andersen, Nov 8, 1999
608 * Fixed a bug where init could hang instead of rebooting.
609 * Removed some debugging noise from init.c
610 * Fixed ln so it works now (it was very broken).
611 * Fixed df so it won't segfault when there is no /etc/fstab,
612 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
613 is not installed (since they cannot fixup "/dev/root" to
614 state the real root device name)
615 * merged some redundant code from mtab.c/df.c into utility.c
617 -Erik Andersen, Nov 5, 1999
620 * More changes -- many thanks to Lineo for paying me to work on
621 busybox. If you have any problems please let me know ASAP at
622 andersen@lineo.com or andersee@debian.org
623 * usage() now prints the BusyBox version. This will help folks
624 realize that they are not in Kansas anymore.
625 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
626 * arguments. Now it doesn't do that. kill wasn't properly accepting
627 * signal names. It does now. Added new apps chvt and deallocvt (I
628 * should probably add open) Major rewrite of init.c. Code is now
629 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
630 * with full regular expressions!). Fixed a stupid seg-fault in sync
631 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
632 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
633 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
634 * cost of ~1.5k and the need for a rw /etc)
635 folks to use a real /etc/mtab file instead of a symlink to
636 /proc/mounts. mount, and umount will add/remove entries and df
637 will now use /etc/mtab if BB_MTAB is defined.
638 * Fixed a nice bug in recursiveAction() which caused it to infinitely
639 hunt through /proc/../fd/* creating new file descriptors if it
640 followed the /dev/fd link over to /proc. recursiveAction() now
641 lstat's the file when followLinks==FALSE so it won't follow links
642 as the name suggests. Fix thanks to Matt Porter
646 -Erik Andersen, Nov 4, 1999
649 * I added a changelog for version 0.30. adjusted find internals to
650 * make it smaller, and removed
652 * Fixed a segfault in ps when /etc/passwd or /etc/group
653 are absent. Now will warn you and carry on.
654 * Added in optional _real_ regular expression support (to be
655 the basis for a future sed utility). When compiled in it adds
656 3.9k, but makes grep much more capable.
657 * Checked out using nftw(3) for recursive stuff, but unfortunatly
658 it wasn't supported before GNU libc 2.1, and some folks use glibc
659 2.0.7 since it is much smaller than that latest and greatest.
661 -Erik Andersen, Oct 21, 1999
664 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
665 paying me to make these updates. If you have any problems with busybox,
666 or notice any bugs -- please let me know so I can fix it. These
670 * busybox can now invoke apps in two ways: via symlinks to the
671 busybox binary, and as 'busybox [function] [arguments]...'
672 * When invoked as busybox, the list of currently compiled in
673 functions is printed out (no this is not bloat -- the list has
674 to be there anyway to map invocation name to function).
675 * busybox no longer parses command lines for apps or displays their
676 usage info. Each app gets to handle (or not handle) this for
678 * Eliminated monadic, dyadic, descend, block_device, and
679 postprocess. It was cumbersome to have so many programs
680 cobbled together in this way. Without them, the app is much
682 * All shared code now lives in utility.c, and is properly
683 ifdef'ed to be only included for those apps requiring it.
684 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
685 so now each app has the function prototype of (da-dum): extern
686 int foo_main(int argc, char** argv); which speeds integration
688 * Adjusted the Makefile to make it easier to
689 {en|dis}able debugging.
690 * Changed default compiler optimization to -Os
691 (optimize for smaller binaries).
694 * To cope with the new app function prototype and the removal of
695 monadic, dyadic, etc, the following apps were re-written:
696 * cat - Works same as always. chgrp, chmod, chown -
697 * rewrite. Combined into a single
698 source file. Absorbed patches from Enrique Zanardi
699 <ezanard@debian.org> that removes the dependency on
700 libc6 libnss* libraries.
701 * cp - Can now do 'cp -a' can can copy devices,
702 pipes, symlinks, as well as recursive or non-recursive
704 * fdflush - adjusted to remove dependancy on struct
705 * FileInfo. find - Now includes some basic regexp matching
706 which will be the basic of a future mini-sed.
707 * ln - Same functionality. mkdir - Added -p flag to
708 * feature set. mv - rewrite. rm - Added -f flag to
709 * feature set. rmdir - Same functionality. swapon,
710 * swapoff - Combined into a single binary. No longer
711 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
713 * touch - Same functionality. date - adjusted with a patch
714 * from Matthew Grant <grantma@anathoth.gen.nz>
715 to accomodate glibc timezone support. I then ripped out GNU
717 * mkswap -- new version merged from util-linux. Can now make
719 * Replaced the old and star, unstar, and tarcat with the tar
720 implementation from sash. Now tar behaves as god intended it
721 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
722 * dd -- rewritten. Can with with files, stdin, stdout. Added the
723 * following new apps: loadfont -- added from debian boot floppies
724 * chroot -- added based on a patch from Paolo Molaro
725 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
726 * simple strings ps -- I just wrote it. Has _no_ options at all,
727 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
729 internationalization and such to make them smaller.
730 * sfdisk -- Added from util-linux (minus
731 * internationalization and such). Probably some other
732 * changes that I forgot to document...
734 -Erik Andersen, Oct 20, 1999
737 This version was a messy pre-alpha. stay away or it will bite you.
738 -Erik Andersen, Sep 24, 1999
741 mini-netcat (mnc) rewritten.
744 Mount now supports -a, and -t auto.
745 Mount now updates mtab correctly for 'ro'.
746 More checks screen rows size, outputs bytes percentage.
747 Printf added as module.
749 Touch now creates files. -c option for no create.
