Rich Felker c0fe5b9da9 check for fd exhaustion in forkpty 
we cannot report failure after forking, so the idea is to ensure prior
to fork that fd 0,1,2 exist. this will prevent dup2 from possibly
hitting a resource limit and failing in the child process. fcntl
rather than dup2 is used prior to forking to avoid race conditions.

Rich Felker d40e344f7b incorrect check for open failure in openpty function 
-1, not 0, indicates failure

Rich Felker 6250c0be4b wordexp cannot use we_offs unless WRDE_DOOFFS flag is set 
previously, a potentially-indeterminate value from we_offs was being
used, resulting in wrong we_wordc and subsequent crashes in the
caller.

Rich Felker d2c604d5a4 protect syslog against cancellation 
these functions are allowed to be cancellation points, but then we
would have to install cleanup handlers to avoid termination with locks
held.

Rich Felker e98bdca9df minimal realpath implementation using /proc 
clean and simple, but fails when the caller does not have permissions
to open the file for reading or when /proc is not available. i may
replace this with a full implementation later, possibly leaving this
version as an optimization to use when it works.

Rich Felker 90f09a0dde remove stupid debug code in wordexp 2011-04-15 12:07:26 -04:00
Rich Felker d251c2645c implement wordexp. first try, may be buggy. intended to be safe. 2011-04-15 12:06:34 -04:00
Rich Felker 19c1830eaa simplify syslog, add vsyslog interface (nonstandard) 
with datagram sockets, depending on fprintf not to flush the output
early was very fragile; the new version simply uses a small fixed-size
buffer. it could be updated to dynamic-allocate large buffers if
needed, but i can't envision any admin being happy about finding
64kb-long lines in their syslog...

Rich Felker a77411a50d remove useless SIGPIPE protection from syslog 
per the standard, SIGPIPE is not generated for SOCK_DGRAM.
 2011-04-13 17:51:45 -04:00
Rich Felker a444ee3410 fix syslog (corrected SIGPIPE blocking, and using dgram instead of stream) 
it actually appears the hacks to block SIGPIPE are probably not
necessary, and potentially harmful. if i can confirm this, i'll remove
them.

Rich Felker 91e836fda7 implement getgrouplist (for initgroups), formerly dummied-out 2011-04-13 09:39:47 -04:00
Rich Felker 750b738e53 add ptsname_r (nonstandard) and split ptsname (standard) to separate file 
this eliminates the ugly static buffer in programs that use ptsname_r.

Rich Felker 9ae8d5fc71 fix all implicit conversion between signed/unsigned pointers 
sadly the C language does not specify any such implicit conversion, so
this is not a matter of just fixing warnings (as gcc treats it) but
actual errors. i would like to revisit a number of these changes and
possibly revise the types used to reduce the number of casts required.
