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