2011-09-16fix ptrace (maybe)Rich Felker-1/+8
2011-09-15implement ptrace syscall wrapper (untested)Rich Felker-0/+18
2011-09-13remove some stray trailing space charactersRich Felker-1/+1
2011-07-30fix some bugs in setxid and update setrlimit to use __synccallRich Felker-2/+27
setrlimit is supposed to be per-process, not per-thread, but again linux gets it wrong. work around this in userspace. not only is it needed for correctness; setxid also depends on the resource limits for all threads being the same to avoid situations where temporarily unlimiting the limit succeeds in some threads but fails in others.
2011-07-22check for fd exhaustion in forkptyRich Felker-2/+15
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.
2011-07-22incorrect check for open failure in openpty functionRich Felker-1/+1
-1, not 0, indicates failure
2011-06-25wordexp cannot use we_offs unless WRDE_DOOFFS flag is setRich Felker-1/+2
previously, a potentially-indeterminate value from we_offs was being used, resulting in wrong we_wordc and subsequent crashes in the caller.
2011-06-18fix memory leak on failure in realpathRich Felker-4/+4
2011-05-29add useless, obsolescent function ulimitRich Felker-0/+19
2011-04-20properly create new session/controlling terminal in forkptyRich Felker-1/+4
2011-04-20implement (nonstandard) forkptyRich Felker-0/+22
2011-04-19block cancellation in wordexp, handle more errorsRich Felker-2/+17
2011-04-19avoid malloc of potentially-large string in wordexpRich Felker-10/+28
2011-04-18protect ftw and nftw against cancellationRich Felker-1/+6
2011-04-18protect syslog against cancellationRich Felker-5/+19
these functions are allowed to be cancellation points, but then we would have to install cleanup handlers to avoid termination with locks held.
2011-04-17minimal realpath implementation using /procRich Felker-0/+43
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.
2011-04-15remove stupid debug code in wordexpRich Felker-1/+0
2011-04-15implement wordexp. first try, may be buggy. intended to be safe.Rich Felker-0/+128
2011-04-13simplify syslog, add vsyslog interface (nonstandard)Rich Felker-31/+36
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...
2011-04-13remove useless SIGPIPE protection from syslogRich Felker-9/+0
per the standard, SIGPIPE is not generated for SOCK_DGRAM.
2011-04-13fix syslog (corrected SIGPIPE blocking, and using dgram instead of stream)Rich Felker-10/+8
it actually appears the hacks to block SIGPIPE are probably not necessary, and potentially harmful. if i can confirm this, i'll remove them.
2011-04-13implement getgrouplist (for initgroups), formerly dummied-outv0.7.8Rich Felker-4/+16
2011-04-13add ptsname_r (nonstandard) and split ptsname (standard) to separate fileRich Felker-11/+16
this eliminates the ugly static buffer in programs that use ptsname_r.
2011-04-12move bswap functions to static inline in byteswap.hRich Felker-16/+0
2011-04-12fix broken bswap_32Rich Felker-1/+1
2011-04-11remove ugly warning-suppression hack from crypt - this invokes UB!Rich Felker-1/+1
2011-03-25fix all implicit conversion between signed/unsigned pointersRich Felker-2/+2
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.
2011-03-20global cleanup to use the new syscall interfaceRich Felker-20/+8
2011-02-16fix compile failure: legacy cuserid needs to define feature testRich Felker-0/+1
2011-02-15fix getrlimit handling on 32-bit systems, and ease porting to 64-bitRich Felker-3/+3
