untangle them:
Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the

the rest if they really need them). (This is preparatory cleanup for adding
a timeout applet like Roberto Foglietta wants.)
Export the itoa (added due to Denis Vlasenko, although it's not quite his
preferred implementation) from xfuncs.c so it's actually used, and remove
several other redundant implementations of itoa and utoa() in the tree.
what to exec. Add -f mode and a brief explanation of how to use it to replace

all of netcat's command line options under two CONFIG entries, so if you
disable both it doesn't use getopt at all.
Both Jason Schoon and Giuseppe Ciotta deserve credit for this, I used elements
of both. It's been upgraded so that you can specify that a given command
should run at create, at delete, or at both using different special characters
(@, $, and * respectively). It uses the system() method of running command
lines which means you can use environment variables on the command line (it
sets $MDEV to the name of the current device being created/deleted, which is
useful if you matched it via regex), and the documentation warns that you need
a /bin/sh to make that work, so you probably want to pick a default shell.

can figure out what header files to include, and override stuff that comes
later. But applets shouldn't include platform.h directly, they should include
busybox.h or libbb.h. Since busybox.h already includes libbb.h, move libbb.h
to the top of busybox.h and platform.h near the top of libbb.h (right after
bbconfig.h, which is something platform.h also needs access to).
While we're at it, move some stuff from busybox.h to libbb.h so we have one
big file to audit/clean up/try to make sense of instead of many.

the side of the tree doesn't _COUNT_, and I will not ship it.
Udhcp was deleted shortly after I posted my philosophy for what should and
shouldn't go into busybox:
http://www.busybox.net/lists/busybox/2006-March/019484.html
I complained about the change t the time. I've complained repeatedly since.
But nobody felt like fixing it. External dependencies are something to be
minimized. I don't care about the ability for packages to build outside
busybox: something is either part of busybox, or it isn't. If I convert any
part of the external udhcp repository to use libbb, I've broken the external
package. Any random cleanups that touch that directory suddenly have to worry
about external dependencies that are NOT OUR PROBLEM. Therefore, that
directory is not and cannot be part of busybox. Wishful thinking isn't going
to change that. I will not ship something I can't maintain.
I'll try to get a new dhcp client and server in before the ship window closes,
but I have a half-dozen other projects pending. I'm sorry this happened, but
I'm not the one who removed it, and I'm not the one who ignored the project
maintainer's repeated complaints about the situation for the next month and a
half.
Here's my attempt at a mini diff applet - it's adapted from the code at
http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/diff/, and only supports
unified diffs.
I've busyboxified everything to a reasonable degree, so I think the code is
suitable enough to be included, but there's still a fair bit of cleaning up
to be done.
For each CONFIG_SYMBOL, include/bb_config.h now has both ENABLE_SYMBOL
and USE_SYMBOL(x). ENABLE_SYMBOL is still always defined (1 or 0) so that
if(ENABLE) should optimize out when it's zero. The USE_SYMBOL(X) will only
splice in X if the symbol is defined, otherwise it'll be empty.
Thus we can convert this:
#ifdef CONFIG_ARGS
opt = bb_getopt_ulflags(argc, argv, "ab:c"
#ifdef CONFIG_THINGY
"d:"
#endif
, &bvalue
#ifdef CONFIG_THINGY
, &thingy
#endif
);
#endif
into this:
if (ENABLE_ARGS) {
opt = bb_getopt_ulflags(argc, argv, "ab:c" USE_THINGY("d:"), &bvalue
USE_THINGY(, &thingy));
}
And it should produce the same code.
Unlike the old versions in include/_usage.h, the new USE_SYMBOL(x) can handle
commas in its arguments (as shown above). (The _usage.h file is obsolete and
no longer generated.)
Nobody should need to include config.h directly anymore, bb_config.h should
define all the configuration stuff we need. Someday, the CONFIG_SYMBOL
versions should go away in favor of ENABLE_SYMBOL and USE_SYMBOL().
Thanks to vodz for the new version of bb_mkdep.c that works with function
macros.
Somehow while applying the bb_do_delay patch a change slipped
in libbb.h that broke compilation.
libbb.h Line 355
extern char bb_path_mtab_file[];
This conflicts with mtab_file.c
#if defined(CONFIG_FEATURE_MTAB_SUPPORT)
const char bb_path_mtab_file[] = "/etc/mtab";
#else
const char bb_path_mtab_file[] = "/proc/mounts";
#endif
Not buying it, eh?
I know I said new features before 1.1, but, well... (I was weak!)
The config file and hotplug modes aren't implemented yet. Might take a stab at
those tomorrow. (I _should_ go back to focusing on the bug triage list.)
CONFIG_ symbol in the kernel, and this clashes with busybox's CONFIG_TR

Since such broken kernel headers are common enough to crop up every few
months, a simple work around is to move TR and WATCHDOG from CONFIG_
to ENABLE_ early.

if(CONFIG_THING) stuff();
And let the compiler do dead code elimination to get rid of it. (Note: #ifdef
will still work because for the 1 case it's a static const int, not a #define.)

Hi Erik,
Hi to all,
This is part five of the my_get*id story.
I've tweaked a bit this two functions to make them more flexible,
but this changes will not affect existing code.
Now they work so:
1) my_getpwuid( char *user, uid_t uid, int bufsize)
if bufsize is > 0 char *user cannot be set to NULL
on success username is written on static allocated buffer
on failure uid as string is written to buffer and NULL is returned
if bufsize is = 0 char *user can be set to NULL
on success username is returned
on failure NULL is returned
if bufsize is < 0 char *user can be set to NULL
on success username is returned
on failure an error message is printed and the program exits
2) 1) my_getgrgid( char *group, uid_t uid, int bufsize)
if bufsize is > 0 char *group cannot be set to NULL
on success groupname is written on static allocated buffer
on failure gid as string is written to buffer and NULL is returned
if bufsize is = 0 char *group can be set to NULL
on success groupname is returned
on failure NULL is returned
if bufsize is < 0 char *group can be set to nULL
on success groupname is returned
on failure an error message is printed and the program exits
This changes were needed mainly for my new id applet.
It is somewhat bigger then the previous but matches the behaviour of GNU id
and is capable to handle usernames of whatever length.
BTW: at a first look it seems to me that it will integrate well (with just a few changes)
with the pending patch in patches/id_groups_alias.patch.
The increase in size is balanced by the removal of my_getpwnamegid.c
from libbb as this was used only in previous id applet and by size optimizations
made possible in whoami.c and in passwd.c.
I know that we are in feature freeze but I think that i've tested it enough
(at least I hope so.......).
Hi,
I've spent the half night staring at the devilish my_getpwuid and my_getgrgid functions
trying to find out a way to avoid actual and future potential buffer overflow problems
without breaking existing code.
Finally I've found a not intrusive way to do this that surely doesn't break existing code
and fixes a couple of problems too.
The attached patch:
1) changes the behaviour of my_getpwuid and my_getgrgid to avoid potetntial buffer overflows
2) fixes all occurences of this function calls in tar.c , id.c , ls.c, whoami.c, logger.c, libbb.h.
3) The behaviour of tar, ls and logger is unchanged.
4) The behavior of ps with somewhat longer usernames messing up output is fixed.
5) The only bigger change was the increasing of size of the buffers in id.c to avoid
false negatives (unknown user: xxxxxx) with usernames longer than 8 chars.
The value i used ( 32 chars ) was taken from the tar header ( see gname and uname).
Maybe this buffers can be reduced a bit ( to 16 or whatever ), this is up to you.
6) The increase of size of the binary is not so dramatic:
size busybox
text data bss dec hex filename
239568 2300 36816 278684 4409c busybox
size busybox_fixed
text data bss dec hex filename
239616 2300 36816 278732 440cc busybox
7) The behaviour of whoami changed:
actually it prints out an username cut down to the size of the buffer.
This could be fixed by increasing the size of the buffer as in id.c or
avoid the use of my_getpwuid and use getpwuid directly instead.
Maybe this colud be also remain unchanged......
Please apply if you think it is ok to do so.
The diff applies on today's cvs tarball (2004-08-25).
Thanks in advance,
Ciao,
Tito
Hi to all,
This patch is useful for:
1) remove an unused var from extern char *find_real_root_device_name(const char* name)
changing it to extern char *find_real_root_device_name(void).
2) fixes include/libbb.h, coreutils/df.c, util-linux/mount.c and util-linux/umount.c accordingly.
3) fixes a bug, really a false positive, in find_real_root_device_name() that happens if
in the /dev directory exists a link named root (/dev/root) that should be skipped but
is not. This affects applets like df that display wrong results

Hi,
Well, I made this patch a long time ago (08/2002) because it was a
need of a project, but had no time to send it to you. It adds support
to `autologin' option of the telnet protocol. It has been used since
made with busybox 0.60.3 at production and I had no problems with it.
I have ported it to the HEAD revision of the CVS server (20040211) and
I hope you enjoy and apply it to the official sources. :)
Thanks a lot!
I had previously provided you with a patch to help complete busybox's
props suite, but have heard no word back. Sense then I've made use of as
many of busybox's native API settings as I could find and would really
love for you to include support for this. If there is something more I
need to do to get this supported added in please let me know.

Hi to all,
here is a new patch for bb's devfsd. The news are:
1) Size reduction for the basic setup with no options compiled in from :
text data bss dec hex filename
10591 392 543 11526 2d06 devfsd.o
rw-r--r-- 1 root root 18536 Dec 18 21:52 devfsd.o
to:
text data bss dec hex filename
9303 392 543 10238 27fe devfsd.o
rw-r--r-- 1 root root 16528 Dec 18 22:02 devfsd.o
With this setup you should not expect much output from devfsd
( just at start or with -v) and if some error occurs it only exits 1.
To have more output enable: " Increases logging (and size)" (+1568 b).
2) The option "Adds function names to program output" was removed from config menu
and now to enable debug output you can use bb's standard option:
"Build BusyBox with Debugging symbols".
Be careful as with this option enabled a lot of data are outputted to /dev/log and/or to stderr.
3) A new option: "Enables the -fg and -np option" was added to config menu (+128 b).
BTW: option "Adds support for MODLOAD keyword in devsfd.conf" adds 268 b.
4) The following keywords in devsfd.conf are supported:
"CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
"PERMISSIONS", "EXECUTE", "COPY", "IGNORE", "MKOLDCOMPAT",
"MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
But only if they are written UPPERCASE!!!!!!!!
5)Help text in usage.h was modified.
6)Something that I have forgotten..........
I've tested this for the last week on my box and it seems to work as expected.
Thanks in advance and please apply.

Dear list,
during my quest do pack busybox into an RPM, I've fixed a small bug
(missing \n) in dc's usage. And added two additional operations: mod and
exp/power.
Feel free to drop them.
Hi Eric
I have written a small patch for the Busybox syslogd. With this patch
one can limit the size of the messagfile. As soon as the limit is
reached the syslogd can rotate or purge the messagefile(s) on his own.
There is no necessity to use an external rotatescript.
Even if logread does something similar, its very handy to have some
messagefile after your box crash.
I wrote this patch initial vor BB 0.6x where no cron daemon was avail.
Now I adapted it for the new Version and i hope it is still useful. At
least I still use it :-)

should we rename the define into CONFIG_FEATURE_HDPARM_HDIO_DMA and
use it for "set" and "get" ???
Since although CONFIG_FEATURE_HDPARM_HDIO_GET_DMA is _not_ set I still

Is this desireable or meant to be like that?
So how about the applied patch?
this patch fixes run_parts when it's called by ifupdown. 1) argv has to be a
NULL terminated char* array, not just a string. 2) run_parts now explicitly
sets the environment. this environment is populated from the
/etc/network/interfaces config file and is needed by the scripts in
/etc/network/if-pre-up.d/. when run-parts is called from the command line the
environment is taken from the current process.

Here's a bunch of fixes for the watchdog app in busybox. This does a
couple of things:
- configurable timer duration (userspace timer duration is
usually configurable within the device drivers themselves).
- run as a daemon
- shutdown the device properly on SIGINT or SIGHUP
- clear the counter immediately instead of sleeping first
as well as updating the usage information. This has also been switched
over to getopt to deal with the optional timer duration specifier.
The changes themselves are harmless and isolated, and I've veried that
this works on sh and x86 without any problems.
The current SC_x references automatically assume that everyone uses ttyS/tts
as their naming scheme for their serial ports. This isn't the case for quite
a few architectures, including sh, sh64, h8, arm, etc.

I rewrite bb_getopt_ulflags() function for more universal usage.
My version support now:
- options with arguments (optional arg as GNU extension also)
- complementaly and/or incomplementaly and/or incongruously and/or list
options
- long_opt (all applets may have long option, add supporting is trivial)
This realisation full compatibile from your version.
Code size grow 480 bytes, but only coreutils/* over compensate this size
after using new function. Last patch reduced over 800 bytes and not full
applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
trivial addition support long_opt with usage new bb_getopt_ulflags().
Complementaly and/or incomplementaly and/or incongruously and/or list options
logic is not trivial, but new "cut" and "grep" applets using this logic
for examples with full demostrating. New "grep" applet reduced over 300
bytes.
Mark,
Also. I removed bug from "grep" applet.
$ echo a b | busybox grep -e a b
a b
a b
But right is printing one only.

- ip route flush
- different usage for telnetd in inetd mode
- changes for the default flags of the ip features
- if no /usr requested, udhcpc should use the script also without /usr.
Apply patch from Ghozlane Toumi to make find smaller by combining
similar error messages
Forward port find -newer support from busybox stable that was
missing from unstable. -Erik.
Fixup usage messages for find. -Erik
Ok. I generate patch for include to busybox-devel my work with
top (original author give me maintaining) and telnetd (my
support and unofficial maintaining) applets. Docs changes
also: added awk, netstat, time applets to list ;)
Hi, Erik.
my_getpw(uid/gid) and applets used it have problem:
if username for uid not found, applets can`t detect it
(but code pessent). Also "%8ld " format is bad:
spaces not required (applets have self format
or spec format (tar applet) and overflow for "id" applet...)
This problem also pressent in stable version.
Patch for unstable in attach.

#49: I found one memory overflow and memory leak in "ln" applet.
Last patch reduced also 54 bytes. ;)
#50: I found bug in loginutils/Makefile.in.
New patch have also new function to libbb and
aplied this to applets and other cosmetic changes.
IPV6 support to busybox. This patch does the following:
* Add IPv6 support to libbb
* Enable IPv6 interface address display
* Add IPv6 config option
* Adds ping6, an adaptation of the ping applet for IPv6
* Adds support routines for ping6:
- xgethostbyname2
- create_icmp6_socket
* Adds ifconfig support for IPv6
* Add support IPv6 to netstat
* Add IPv6 support to route
Thanks Bart!
- Made a new dir loginutils
- Moved all applets from pwd_grp to loginutils
- Added new applets su.c login.c to loginutils
- Made a new dir libpwdgrp
- Moved everything from pwd_grp/libpwd_grp there
- Added shadow.c to libpwdgrp
- Removed dir pwd_grp
- Added usage strings for login and su to usage.h
- Changed main Makefile to reflect the dir rearrangements
[Parts of this patch may overlap with my other two patches]
1) tinylogin like with compile time selection and a chown root.root
2) Runtime configurable via /etc/busybox.conf (docu is in the works)
[Parts of this patch may overlap with my other two patches]
(bunzip2_main): Read data from standard input if FILE argument is `-' or
omitted.
* include/usage.h (bunzip2_trivial_usage, bunzip2_full_usage): Rewrite.
* testsuite/bunzip2/bunzip2-reads-from-standard-input: New.
Very minimal last corrections:
1) busybox.c: fix warining
2) docs/: add applets for list from pwd_grp
3) usage.h: add -n option for route
4) run_parts.c: many todo fix for busybox style
5) addgroup.c: add #ifdef CONFIG_FEATURE_SHADOWPASSWDS, reduce one
perror_msg
6) adduser.c: fix bug "variable i not initialize" and
add #ifdef CONFIG_FEATURE_SHADOWPASSWDS
that into a pid_t, which is unsigned on a number archs. Furthermore,
find_pid_by_name() would _never_ return an error if the intended proces
was "init", but instead would return 1, meaning we would fail to work
on 2.4.x kernels running an initrd...

Kimdon <dwhedon@gordian.com> on october 7th -- the day I was fired from
Lineo. So it seems I totally forgot about this patch until now.
Sorry about that David!
This code could be improvemed by
1) supporting more options,
2) Creating a shared crc table with gunzip, or perhaps generated on the fly.
3) Removing any remaining unneccessary code (e.g. if (noisy))
There is some optimization that can be done to better use libbb in
these applets. There is also redundancy between stty and getty which
could be eliminated.
-Erik
math suport, cleaner math syntax error checking, moves redundant signal
string tables (from kill and ash) into libbb and provides a few
cleanups elsewhere.
was written by Aaron Lehmann <aaronl@vitelus.com> for busybox. This
patch makes a few trivial changes to Aaron's code so that it can be
used (in theory) by the other shells as well...
