3f3aa2a57d make xfunctions optionally longjump instead of exit. 
use it for making NOFORK more practical.

c44ab01b75 Improve STANDALONE_SHELL. "safe" applets are renamed NOEXEC applets 
and now this fact is recorded in applets.h, not ash.c.

Several fixes to "--help + STANDALONE_SHELL" scenarios.

./busybox ash -c 'i=20000; while test $i != 0; do touch z; i=$((i-1)); done'
runs more than twice as fast with STANDALONE_SHELL versus without.

53091ecd20 Attempt to get more applets compile for NOMMU. 
TODO_config_nommu documents what I managed to compile so far
(yay! msh works! cool). inetd, telnetd, httpd still do not compile. TODO

(in addition to erros on link stage).

9067f13be0 NOMMU re-exec trick shuld not depend on existence of "don't daemonize" 
option for every affected applet (and dnsd, for example, don't have one).
Thus rework re-exec support to not require it. Code got smaller too.

 2007-01-14 13:12:06 +00:00
Denis Vlasenko
7a431b3715 By popular request reinstate fakeidentd's standalone mode. 
Since this is also needed for other applets like telnetd,
introduce generic driver for such things.
It even supports inetd-wait ('linger') mode, when inetd
hands out listen socket to child and waits to it to die,
instead of handing out accepted socket and continuing
listening itself (nowait mode).
Code growth ~200 bytes.
NB: our inetd doesn't support wait mode yet (or mabe it is buggy).

9de420c27c Improve generic ipv4+ipv6 support in libbb. 
Convert telnet to it. Now this works:
telnetd -b [::1]:1234 - bind to IPv6 non-standard port
telnet [::1]:1234 - connect to IPv6 non-standard port
telnet ::1 1234 - same
This does not require ANY ipv6-specific code in applets
(no struct sockaddr_in6. In fact, no sockaddr_in, too).

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on

Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

eb84a42fdd The Software Freedom Law Center wants us to add a copyright notice to the 
generated binaries, to make copyright enforcement easier.  Our liason with
them (Bradley Kuhn) suggested the following text:

> Copyright (C) YEAR-2006  Erik Andersen, Rob Landley, and others.
> Licensed under GPLv2.  See source distribution for full notice.

And the busybox help message seems the least offensive place to put it.  (At
some point in the future, I need to strip 128 bytes from the binary to feel
good about this, though. :)

Minor header file cleanup while I was there, since libbb.h already #includes
most of that stuff...

00d7d6cef6 nfsmount: sanitize it. It had a rather peculiar idea of implementing "bg" 
option - it was going to return a special flag back to caller and
expecting caller to call it again with special parameter! Also
caller was charged with calling mount() syscall...

mount: mtab support was non-functional. Enabling it revealed serious bug
which is not fixed yet.

untangle them:

Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the
signal list to that required by posix (they can specify the numbers for
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.

6ab037872f made "test" an ash built-in. 
moved the contents of libbb/bb_echo.c back into coreutils/echo.c,
which is a more reasonable place for them than libbb.  this
forces anyone who wants echo and test to be builtin to ash to
also have them available as applets.  their cost is very small,
and the number of people who wouldn't want them as applets is
also very small.

added warning about shell builtins vs. CONFIG_FEATURE_SH_STANDALONE_SHELL,
which conflicts with their use.

thanks to nathanael copa for debugging help.

some string size optimization in test.c may have been lost with
this commit, but this is a good new baseline.

b623a542df Header file cleanup. platform.h apparently needs to be included early on so it 
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.

34b5319d86 Make md5 calculation always go through an the buffer so that A) we don't 
handle packets out of sequence if some data goes through the buffer and
some doesn't, B) it works on systems that can't handle aligned access,
C) we just have one code path to worry about.

While we're at it, sizeof() and RESERVE_CONFIG_BUFFER() really don't combine
well, which is why md5sum has been reading and processing data 4 bytes at a
time.  I suspect that the existence of CONFIG_MD5_SIZE_VS_SPEED to do loop
unrolling and such in the algorithm was an attempt to work around that bug.

6a6798b8e4 Major rewrite of mount, umount, losetup. Untangled lots of code, shrunk 
things down a bit, fixed a number of funky corner cases, added support for
several new features (things like mount --move, mount --bind, lazy unounts,
automatic detection of loop mounts, and so on).  Probably broke several
other things, but it's fixable.  (Bang on it, tell me what doesn't work for
you...)

Note: you no longer need to say "-o loop".  It does that for you when
necessary.

Still need to add "user mount" support, which involves making mount suid.  Not
too hard to do under the new infrastructure, just haven't done it yet...

The previous code had the following notes, that belong in the version
control comments:

- * 3/21/1999   Charles P. Wright <cpwright@cpwright.com>
- *             searches through fstab when -a is passed
- *             will try mounting stuff with all fses when passed -t auto
- *
- * 1999-04-17  Dave Cinege...Rewrote -t auto. Fixed ro mtab.
- *
- * 1999-10-07  Erik Andersen <andersen@codepoet.org>.
- *              Rewrite of a lot of code. Removed mtab usage (I plan on
- *              putting it back as a compile-time option some time),
- *              major adjustments to option parsing, and some serious
- *              dieting all around.
- *
- * 1999-11-06  mtab support is back - andersee
- *
- * 2000-01-12   Ben Collins <bcollins@debian.org>, Borrowed utils-linux's
- *              mount to add loop support.
- *
- * 2000-04-30  Dave Cinege <dcinege@psychosis.com>
- *             Rewrote fstab while loop and lower mount section. Can now do
- *             single mounts from fstab. Can override fstab options for single
- *             mount. Common mount_one call for single mounts and 'all'. Fixed
- *             mtab updating and stale entries. Removed 'remount' default.

0b62158475 implemented a builtin echo command in ash. moved the guts of the 
echo applet into libbb, and now call bb_echo() from both echo.c
and ash.c

193c8c7383 #ifdef reduction infrastructure, based on an argument between Shaun Jackman, 
Rob Landley, and others.

Currently CONFIG options are defined or undefined, so we chop out code with
#ifdefs, ala:
#ifdef CONFIG_THING
  stuff();
#endif

This creates a new header file, bb_config.h, which sets the CONFIG entry to 1
or 0, and lets us do:

  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.)
