3 * tar wouldn't create directory entries that don't end in '/',
4 now it does (thanks to Avery Pennarun <apenwarr@worldvisions.ca>)
5 * Several fixes from Pavel Roskin <pavel_roskin@geocities.com>:
6 - When `tail' fails to open a file it now exits.
7 - When `syslogd' is given the `-n' option it should still use
8 fork() for running klogd.
9 * nslookup types are now changed to u_int32_t (instead of uint32_t)
10 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
11 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
12 to count hard-linked files more then once). Many thanks to
13 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
14 * Removed /proc dependancies for init and free (while maintaining
15 exactly the same functionality). /proc takes up 90k of kernel
16 space, so it is nice to avoid using it at all costs.
17 * init no longer tries to mount /proc (unless there is less the 1 meg
18 free). Use of /proc (or not) is policy that should be set up in
19 /etc/fstab (or in hardcoded scripts), not in init.
20 * Fixed rebooting when init runs as an initrd.
27 * Fairly massive restructuring of umount.c to deal with remounting
28 busy devices read-only. Adds a -r option to control that; it is
29 optionally compiled in with BB_FEATURE_REMOUNT
30 * Added a bunch of functions to mtab.c to interact with the
31 {get,set,end}mntent interface; as it turns out, those functions do
32 not appear to be re-entrant, and that causes a lot of problems with
33 the way umount was originally written.
34 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
35 to be more consistent with sysvinit
36 * Changes to init.c to use the new -r option to umount. Also increased
37 the sleep time between the time the TERM and KILL signals are sent
42 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
43 extensively rewritten from the original cp.c.
44 * Fixed cp and mv so if the source and destination are a the
45 same directory it will print an error and continue.
46 * Also added a warning message to the `mv' usage string saying that
47 this is not GNU mv, and it will break hard links. cp also breaks
49 * ln.c: implemented `-n' switch, no-deref symlinks.
50 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
51 * name buffer overrun guards to prevent future crashes.
52 - Always check exit status.
53 - Purge all use of `creat()', replace with `open()'.
55 - recursiveAction was overriding the value of followLinks thus
57 - isDirectory now takes a followLinks boolean, updated all callers
58 - copyFile had the followLinks logic reversed.
59 * messages.c: New file. Put common error message strings all in
60 one place in an attempt to shrink the binary a little.
65 * changed fsck_minix.c to reduce its .bss size significantly
67 * Made tar creation support in busybox tar optional. You no longer
68 * _have_ to put a "-" in front of tar options. Tar could inadvertently
69 * change permissions and ownership on
70 certain directories pointed to by symlinks.
71 * Made grep and grep -h do the right thing wrt printing
72 the file name (it failed to print files names in many cases).
73 * Fix a namespace aliasing problem wereby if du was built in, the
74 symlink for both du and dutmp would be installed, or then rm was
75 built in, the symlinks for both rm and rmmod would be installed.
76 * Added a closelog() to init.c after loging -- fix thanks to
77 Taketoshi Sano <kgh12351@nifty.ne.jp>
78 * Rewrote and simplified logger. Added the "-t" option, and made it
79 behave itself a bit better.
80 * Optional support contributed by Ben Collins <bcollins@debian.org>
81 for the kernel init chroot patch by Werner Almesberger, which
82 allows init to chroot to a new device, and umount the old one.
83 * Fixed bug that wouldn't let one chown a symlink -- it would
84 always dereference before. -beppu
85 * Fixed a bug where init could have reference already freed memory.
86 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
87 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
88 * Added (and documented) "-n" option for head
89 * Cleanup for a number of usage messages -- also
90 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
91 * Cosmetic fix to busybox.c (Don't print a comma at the
92 end of line if there are no more application names).
93 * Fixed a stupid bug in "head" option handling ("head -n"
95 * Moved commonly used functions "xmalloc()" and "exit()"
96 to utility.c (with proper #ifdef's).
97 * Created a tiny tail implementation, removing -c, -q, -v, and making
98 tail -f work only with a single file. This reduced tail from 6k to
99 2.4k. The bigger/more featured tail can still be had by disabling
100 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
101 * Ping now falls back to doing the right thing if /etc/protocols
103 * Fixed mount and umount. Previously they could leak loop device
104 allocations, causing the system to quickly run out. Fix for umount
105 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
106 * ls formatting on eight charactor user names fixed by
107 Randolph Chung <tausq@debian.org>.
108 * cp could, when copying symlinks, change permissions of the
109 files pointed to by the symlinks.
110 * Several fixes from Pavel Roskin <pavel_roskin@geocities.com>:
111 - `chown' with 1 argument displayed the error incorrectly
112 - `fdflush', `length' and `printf' crashed if run without arguments
113 - `fdflush' tried to flush itself using *argv
114 - added "skip" and "seek" to dd.
115 - ls no longer messus up output when combining files and
116 directories on the command line
117 * swapoff -a was not working. Now it is.
118 * init did not cleanly unmount filesystems on reboot. Now it does.
119 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
121 * Some architectures (PowerPc) assume chars are unsigned, so they could
122 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
123 * Began converting error handling to use some common routines
125 * syslogd now has better message handling and ignores SIGHUP.
126 * install.sh had a bug preventing installation to the specified
127 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
128 * You can now spefify alternative strip commands -- change
129 also from Gilbert Coville.
135 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
136 by Edward Betts <edward@debian.org>
137 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
138 type commands (file in a directory to another directory) from
140 * Fixed a logger bug that caused garbage to be written to the syslog
141 (unless you used busybox syslog, which hid the bug). Thanks to
142 Alex Holden <alex@linuxhacker.org> for the fix.
143 * /bin/true and /bin/false were echoing a blank line when run.
145 * mkdir -p would print an error when asked to mkdir an existing dir
146 with no interveining subdirectories.
147 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
148 * and support in umount for loop
149 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
150 <bcollins@debian.org>
151 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
152 * fullWrite() not only if BB_TAR is defined, but also
153 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
154 * add some compiler optimizations to further reduce executable size
155 (as a side note, on my machines the largest code is generated
156 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
158 * Compile now won't fail if busybox.def.h defines
159 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
160 referenced, but not compiled)
161 * Fixed a bug in setting TERM for serial console support. TERM now
162 defaults to "ansi" for serial consoles.
163 * Fixed a bug in handling the CONSOLE env. variable for serial
166 -Erik Andersen, Jan 15, 2000
169 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
170 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
171 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
172 for loading application character maps for Unicode fonts.
173 * Major init re-work. init now supports inittab (slightly different
174 but similar to sysvinit), allowing me to get all the policy out of
175 init and into the conf file. It works just fine without inittab
176 being present, but if you dont like the defautl behavior you can
177 now do something about it. Init is much cleaner as a result.
178 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
179 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
180 * failure of 'logger -p'. -erik Added the -s option to du -beppu
181 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
182 with the 2.0.x Linux kernel.
183 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
185 * Grep -i previously failed on UPPER CASE patterns due to a silly
186 regexp implementation bug that is now fixed.
187 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
188 * Fixed a bug where tar would not set the user and group on device
190 * Fixed a bug where tar would not restore the time to files. Fixed a
191 * major security problem with tar -- it changed ownership
192 of any file pointed to by a symlink to 777 (like say libc....)
194 * cp and mv were very broken when moving directories. I have rewritten
195 them so they should now work as expected.
196 * sed now supports addresses (numeric or regexp, with negation) and
197 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
198 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
199 * Some cosmetic fixes to ls output formatting to make it behave more
201 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
202 * <fwv@myrtle.lahn.de>:
203 - Added gunzip -t, removed gunzip.c dead code,
204 - fixed several typos
205 - Glibc 2.0.7 and libc5 compile fixes
206 * Fixed a bug where 'mknod --help' would segfault.
209 -Erik Andersen, Jan 07, 2000
212 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
213 <tausq@debian.org>. 3 items off the TODO list!
214 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
215 * tail from GNU textutils-1.19, but adjusted
216 to suit my evil purposes. Costs 6k. I'll make it smaller
218 * on reboot, init called 'umount -a -n', which caused errors
219 when BB_MTAB was not enabled. Changed to 'umount -a', which does
221 * init will now try to run /sbin/getty if it is present (for easy
222 integration with the about-to-be-released tinylogin.)
223 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
224 * -l' was failing on long directories, since my_getid was leaking
225 one file descriptor per file. Oops.
226 * Fixed rebooting from init. I'd accidently left some debugging code
228 which blocked reboots.
229 * Fixed reboot, halt (and added poweroff) such that they handle it when
230 init is not at PID 1 (like when running in an initrd).
231 * Added a prelinary du implementation. Some parameter parsing
232 stuff still needs to be added. -beppu (John Beppu
234 * Implemented tee. -beppu Implemented head. -beppu
236 -Erik Andersen, Dec 10, 1999
239 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
241 * df will not exit on error, but will stat all mounted filesystems.
242 * Fixed tar so uid/gid/permissions on extracted tarballs will be
244 * Fixed find -name so it properly uses shell wildcard patterns
245 (i.e. `*', `?', and `[]') instead of regular expressions, which
246 was causing some confusing and unexpected behavior.
247 * Added klogd to syslogd, so now the log will contain both system and
249 * syslogd now creates the /dev/log socket to make sure it is there, and
250 is actually a socket with the right permissions.
251 * I've taken a first step to making busybox not need the /proc
252 filesystem. Most apps don't need it. Those that _require_ it,
253 will complain if you enable them when you disable
254 BB_FEATURE_USE_PROCFS.
256 -Erik Andersen, Dec 5, 1999
259 * Wrote a micro syslogd, and a logger util (to log things to the syslog
260 from the command line or scripts) With both compiled in, costs 4k.
261 * Fixed 'make install' so symlinks are installed in their proper
262 * locations. Changed the build system slightly so that features can
264 or disabled from the busybox.defs.h header file, without trying to
265 compile in a source file named after that featue (unless that file
267 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
268 * -r' both work. dd now properly handles input beyond 1 block from
269 * stdin. Fixed a bug where tar unpacked everything a directories.
271 from createPath into mkdir where it belonged, thereby making tar
273 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
275 last file in the list.
276 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
278 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
279 are presented properly.
283 -Erik Andersen, Nov 25, 1999
286 * fixed dd so it properly defaults to stdin and stdout when no
287 if= and of= are set (fix thanks to Eric Delaunay).
288 * Don't try to close the file descriptor of a pipein tar. (fix also
291 * Made createPath be quiet (again thanks to Eric Delaunay). If
292 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
293 command you define it as will be run if the init script exits.
294 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
295 * NFS support added to mount by Eric Delaunay. It costs 10k when
297 in, but that is still a big win for those that use NFS.
298 * Made 'rm -f' be silent for non-existant files (thanks to Eric
299 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
301 and acts as god intended gunzip and zcat to act. They answer
302 --help and obey the '-c' flag.
303 * Fixed a bug in mv which caused it to not move files when the
306 * Fixed a decimal-instead-of-octal bug causing mkdir to make
308 with very wrong permissions.
309 * chmod would overwrite file permissions instead of modifying them.
310 Now it properly modifies permissions.
311 * Init now sends warnings destined for the console to /dev/console to
313 they show up on whatever the active console it. Otherwise
314 important messages (for example that the system is rebooting) were
315 not seen when switched to a different VT.
317 -Erik Andersen, Nov 17, 1999
320 * gzip now obeys the principle of least surprise and acts like god
322 (i.e. it accepts a file name, answers --help, and obeys the '-c'
323 flag and only then outputs to stdout).
324 * Fixed more.c to compile autowidth on sparc and set initial winsize
325 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
327 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
328 * tar now accepts --help chmod, chown, and chgrp usage now works
329 * General usage (i.e. --help) cleanups for most apps umount now parses
330 * options correctly tar can now unpack tarballs containing device
332 sockets, and fifos (though it can't pack them up) thanks to Matt
333 Porter. Creating archives containing these is still left to the
335 * fixed up the license in more.c to properly point to Bruce Perens.
337 -Erik Andersen, Nov 11, 1999
340 * ls -l now displays link names outside the current directory,
341 Patch thanks to Eric Delaunay
342 * init now properly handles sparc serial consoles and does a
343 better job of finding the real console device rather than using
344 /dev/console which doesn't support job control. Patch also thanks
346 * more started to read from stdin after the last file was finished, and
347 options were not parsed correctly (fix thanks to Eric Delaunay).
348 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
349 * rm wouldn't remove a symlink unless the symlink was valid. This was
350 a side effect of the busybox 0.32 recursiveAction() fix. Things
351 should now work correctly.
352 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
353 * it does. sed was appending a \n to the end of lines with
355 Now it doesn't do that.
356 * ls -l now bypasses libc6 nss when displaying user/group names.
357 Now uses my_getpwuid and my_getgrgid.
359 -Erik Andersen, Nov 8, 1999
362 * Fixed a bug where init could hang instead of rebooting.
363 * Removed some debugging noise from init.c
364 * Fixed ln so it works now (it was very broken).
365 * Fixed df so it won't segfault when there is no /etc/fstab,
366 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
367 is not installed (since they cannot fixup "/dev/root" to
368 state the real root device name)
369 * merged some redundant code from mtab.c/df.c into utility.c
371 -Erik Andersen, Nov 5, 1999
374 * More changes -- many thanks to Lineo for paying me to work on
375 busybox. If you have any problems please let me know ASAP at
376 andersen@lineo.com or andersee@debian.org
377 * usage() now prints the BusyBox version. This will help folks
378 realize that they are not in Kansas anymore.
379 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
380 * arguments. Now it doesn't do that. kill wasn't properly accepting
381 * signal names. It does now. Added new apps chvt and deallocvt (I
382 * should probably add open) Major rewrite of init.c. Code is now
383 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
384 * with full regular expressions!). Fixed a stupid seg-fault in sync
385 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
386 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
387 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
388 * cost of ~1.5k and the need for a rw /etc)
389 folks to use a real /etc/mtab file instead of a symlink to
390 /proc/mounts. mount, and umount will add/remove entries and df
391 will now use /etc/mtab if BB_MTAB is defined.
392 * Fixed a nice bug in recursiveAction() which caused it to infinitely
393 hunt through /proc/../fd/* creating new file descriptors if it
394 followed the /dev/fd link over to /proc. recursiveAction() now
395 lstat's the file when followLinks==FALSE so it won't follow links
396 as the name suggests. Fix thanks to Matt Porter
400 -Erik Andersen, Nov 4, 1999
403 * I added a changelog for version 0.30. adjusted find internals to
404 * make it smaller, and removed
406 * Fixed a segfault in ps when /etc/passwd or /etc/group
407 are absent. Now will warn you and carry on.
408 * Added in optional _real_ regular expression support (to be
409 the basis for a future sed utility). When compiled in it adds
410 3.9k, but makes grep much more capable.
411 * Checked out using nftw(3) for recursive stuff, but unfortunatly
412 it wasn't supported before GNU libc 2.1, and some folks use glibc
413 2.0.7 since it is much smaller than that latest and greatest.
415 -Erik Andersen, Oct 21, 1999
418 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
419 paying me to make these updates. If you have any problems with busybox,
420 or notice any bugs -- please let me know so I can fix it. These
424 * busybox can now invoke apps in two ways: via symlinks to the
425 busybox binary, and as 'busybox [function] [arguments]...'
426 * When invoked as busybox, the list of currently compiled in
427 functions is printed out (no this is not bloat -- the list has
428 to be there anyway to map invocation name to function).
429 * busybox no longer parses command lines for apps or displays their
430 usage info. Each app gets to handle (or not handle) this for
432 * Eliminated monadic, dyadic, descend, block_device, and
433 postprocess. It was cumbersome to have so many programs
434 cobbled together in this way. Without them, the app is much
436 * All shared code now lives in utility.c, and is properly
437 ifdef'ed to be only included for those apps requiring it.
438 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
439 so now each app has the function prototype of (da-dum): extern
440 int foo_main(int argc, char** argv); which speeds integration
442 * Adjusted the Makefile to make it easier to
443 {en|dis}able debugging.
444 * Changed default compiler optimization to -Os
445 (optimize for smaller binaries).
448 * To cope with the new app function prototype and the removal of
449 monadic, dyadic, etc, the following apps were re-written:
450 * cat - Works same as always. chgrp, chmod, chown -
451 * rewrite. Combined into a single
452 source file. Absorbed patches from Enrique Zanardi
453 <ezanard@debian.org> that removes the dependency on
454 libc6 libnss* libraries.
455 * cp - Can now do 'cp -a' can can copy devices,
456 pipes, symlinks, as well as recursive or non-recursive
458 * fdflush - adjusted to remove dependancy on struct
459 * FileInfo. find - Now includes some basic regexp matching
460 which will be the basic of a future mini-sed.
461 * ln - Same functionality. mkdir - Added -p flag to
462 * feature set. mv - rewrite. rm - Added -f flag to
463 * feature set. rmdir - Same functionality. swapon,
464 * swapoff - Combined into a single binary. No longer
465 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
467 * touch - Same functionality. date - adjusted with a patch
468 * from Matthew Grant <grantma@anathoth.gen.nz>
469 to accomodate glibc timezone support. I then ripped out GNU
471 * mkswap -- new version merged from util-linux. Can now make
472 * >128Meg swaps. Replaced the old and star, unstar, and tarcat
474 implementation from sash. Now tar behaves as god intended it
475 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
476 * dd -- rewritten. Can with with files, stdin, stdout. Added the
477 * following new apps: loadfont -- added from debian boot floppies
478 * chroot -- added based on a patch from Paolo Molaro
479 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
480 * simple strings ps -- I just wrote it. Has _no_ options at all,
481 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
483 internationalization and such to make them smaller.
484 * sfdisk -- Added from util-linux (minus
485 * internationalization and such). Probably some other
486 * changes that I forgot to document...
488 -Erik Andersen, Oct 20, 1999
491 This version was a messy pre-alpha. stay away or it will bite you.
492 -Erik Andersen, Sep 24, 1999
495 mini-netcat (mnc) rewritten.
498 Mount now supports -a, and -t auto.
499 Mount now updates mtab correctly for 'ro'.
500 More checks screen rows size, outputs bytes percentage.
501 Printf added as module.
503 Touch now creates files. -c option for no create.
