libbb: rename xgetcwd and xreadlink
|
|
no preceding prototype
|
|
|
|
prototypes (heresy!), add spaces in places like "flags&NETSTAT_CONNECTED",
removed unused #defines, #ifdef -> #if, use uint32_t for ipv4 addrs.
|
|
so rename stuff accordingly.
|
|
(make history and completion optional at runtime).
Use it for fdisk, as an example.
Some unrelated fixes in fdisk are also here.
|
|
(will close all fd's > 2 on daemonization now)
getty: fix "getty -" support, and also do not try to chown/chmod "-"
telnetd: fix "lost ctty" bug
Yet another attempt on saner function names:
bb_sanitize_server_stdio(0/1) -> bb_sanitize_stdio() + bb_daemonize();
|
|
last xcalloc replaced by xzalloc
|
|
|
|
|
|
|
|
|
|
|
|
|
|
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

- use CONFIG_BUSYBOX_EXEC_PATH as before it one was broken by a recent revert.
- use xchdir() since all is invain if it fails there anyways, supposedly

things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes... General cleanup pass. What I've
been doing for the last couple days.
And it conflicts! I've removed httpd.c from this checkin due to somebody else
touching that file. It builds for me. I have to catch a bus. (Now you know
why I'm looking forward to Mercurial.)

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.

This bug is in busybox 1.0.0-rc2. When using lash exec
builtin with redirection, the opened file fd keep increasing.
For example, please try the following command with lash.
ls -al /proc/<lash pid>/fd
exec /bin/sh 2>/dev/null
ls -al /proc/<lash pid>/fd
The last 'ls' command output will look like this. The fd
number 4 shouldn't exist.
lrwx------ 1 501 100 64 Aug 13 13:56 4 -> /dev/pts/5
l-wx------ 1 501 100 64 Aug 13 13:56 2 -> /dev/null
lrwx------ 1 501 100 64 Aug 13 13:56 1 -> /dev/pts/5
lrwx------ 1 501 100 64 Aug 13 13:56 0 -> /dev/pts/5
dr-xr-xr-x 3 501 100 0 Aug 13 13:56 ..
dr-x------ 2 501 100 0 Aug 13 13:56 .
This one-line patch fix this problem by setting CLOEXEC flag for
squirrel fd. Please apply.

It looks like latest uClibc defines ARCH_HAS_MMU, but a few busybox files
test UCLIBC_HAS_MMU, resulting in vfork() getting called instead of
fork(), etc.
Patch below. Only tested for lash.
Cheers,
