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