executable if we asked to exec someting with argv[0] == known_applet"
Use it in init. Also respect PATH in init, remove explicit "/sbin" etc
from exec. Patch by Gabriel L. Somlo <somlo@cmu.edu>
|
|
Precaution
|
|
(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();
|
|
(name is still bad - it doesn't hint that function
may do daemonization trick for you if asked to).
Small fixes to fakeidentd.
|
|
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).

platform.h: define strchrnul for dietlibc
ash: stop using few non-standard functions
|
|
xfuncs: add dprintf for dietlibc
|
|
assorted strtoul fixes (that's what brought me into minix)...
|
|
fix xstrdup to not grossly overallocate memory
use xopen instean of xopen3 in several places
etc.
|
|
bb_full_fd_action: optimize
die_if_ferror: "<applet>: filename" isn't a good err msg, add "..I/O error"
|
|
(GNU extensions 'K' and 'L').
We correctly handle them when untarring now, but unfortunately
we still don't use them when tarring! That stupid 100 char limit
is still there!
The biggest problem is that we don't support 'pax' tar format.
Linux kernel tarballs are in this format... shame

What if I need to have both?? This patch introduces
CONFIG_FEATURE_TELNETD_STANDALONE: y - both, n - only inetd.

It's "nice" on steroids - can set uid/gid, mem/cpu limits etc. +3.5k

bb_xx_msg calls, and convert networking/* to it.
The rest of bbox will be converted gradually.

were using "1" as one of the arguments anyway, and as for the rest a multiply
and a push isn't noticeably bigger than pushing two arguments on the stack.

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.)

xlseek and fdlength() for the new mkswap.

prevent a process from switching to a user that has too many processes, and
when that happens WE'RE STILL ROOT. See http://lwn.net/Articles/190331/
