2011-04-11fix fputwc return valueRich Felker1-1/+1
2011-04-11remove ugly warning-suppression hack from crypt - this invokes UB!Rich Felker1-1/+1
2011-04-11update README since we now DO have a mailing listRich Felker1-4/+4
2011-04-10add some ugly legacy type names in sys/types.h (u_char etc.)Rich Felker1-0/+8
2011-04-10add legacy BSD-style timer*() macros in sys/time.hRich Felker1-0/+10
2011-04-10add missing UTIME_* macros in sys/stat.hRich Felker1-0/+3
2011-04-10add missing float.h macrosRich Felker2-0/+6
actually FLT_ROUNDS needs to expand to a static inline function that obtains the current rounding mode and returns it, but that will be added later with fenv.h stuff.
2011-04-09run pthread tsd destructors when a timer thread pretends to exitRich Felker1-0/+6
2011-04-09greatly improve SIGEV_THREAD timersRich Felker3-15/+21
calling pthread_exit from, or pthread_cancel on, the timer callback thread will no longer destroy the timer.

2011-04-09work around a nasty bug in linux readv syscallRich Felker1-3/+4
according to posix, readv "shall be equivalent to read(), except..." that it places the data into the buffers specified by the iov array. however on linux, when reading from a terminal, each iov element behaves almost like a separate read. this means that if the first iov exactly satisfied the request (e.g. a length-one read of '\n') and the second iov is nonzero length, the syscall will block again after getting the blank line from the terminal until another line is read. simply put, entering a single blank line becomes impossible. the solution, fortunately, is simple. whenever the buffer size is nonzero, reduce the length of the requested read by one byte and let the last byte go through the buffer. this way, readv will already be in the second (and last) iov, and won't re-block on the second iov.
2011-04-08better fix sysconf pthread stack minRich Felker1-1/+1
2011-04-08consistency with pthread stack min in limits.hRich Felker1-1/+1
2011-04-08fix broken sigsetjmp on x86_64Rich Felker1-7/+9
2011-04-08workaround broken msghdr struct on 64bit linuxRich Felker3-2/+23
POSIX clearly specifies the type of msg_iovlen and msg_controllen, and Linux ignores it and makes them both size_t instead. to work around this we add padding (instead of just using the wrong types like glibc does), but we also need to patch-up the struct before passing it to the kernel in case the caller did not zero-fill it. if i could trust the kernel to just ignore the upper 32 bits, this would not be necessary, but i don't think it will ignore them...
2011-04-08fix ipv6 address printing: 2001 appeared as 201, etc.Rich Felker1-3/+5
2011-04-08fix broken dns response parsing code that made most ipv6 lookups failRich Felker1-4/+6
2011-04-08return the requested string as the "canonical name" for numeric addressesRich Felker1-0/+1
previously NULL was returned in ai_canonname, resulting in crashes in some callers. this behavior was incorrect. note however that the new behavior differs from glibc, which performs reverse dns lookups. POSIX is very clear that a reverse DNS lookup must not be performed for numeric addresses.

2011-04-07fix breakage due to converting a return type to size_t in iconv...Rich Felker1-1/+1
2011-04-06fixed crash in new rsyscall (failure to set sa_flags for signal handler)Rich Felker1-0/+2
2011-04-06consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefixRich Felker38-40/+40
2011-04-06move rsyscall out of pthread_create moduleRich Felker10-109/+133
this is something of a tradeoff, as now set*id() functions, rather than pthread_create, are what pull in the code overhead for dealing with linux's refusal to implement proper POSIX thread-vs-process semantics. my motivations are: 1. it's cleaner this way, especially cleaner to optimize out the rsyscall locking overhead from pthread_create when it's not needed. 2. it's expected that only a tiny number of core system programs will ever use set*id() functions, whereas many programs may want to use threads, and making thread overhead tiny is an incentive for "light" programs to try threads.
2011-04-06pthread exit stuff: don't bother setting errno when we won't check it.Rich Felker1-2/+2
2011-04-06fix rsyscall handler: must not clobber errno from signal contextRich Felker1-2/+4
2011-04-06fix typo in sys/msg.hRich Felker1-1/+1
2011-04-06add startup abi functions, dummy for now. eventually needed for c++ support.Rich Felker2-0/+10
2011-04-06add _res (__res_state()) dummyRich Felker1-0/+9
2011-04-06add IN_LOOPBACKNET constant (nonstandard but in reserved namespace)Rich Felker1-0/+2

2011-04-06fix prototype for strsepRich Felker2-1/+2
2011-04-06fix completely bogus loop condition in getmntent_rRich Felker1-1/+1
somehow this worked on my simple fstab, but horribly broke in general, leading to use of uninitialized offset array and crashes.
2011-04-06major semaphore improvements (performance and correctness)Rich Felker5-21/+37
1. make sem_[timed]wait interruptible by signals, per POSIX 2. keep a waiter count in order to avoid unnecessary futex wake syscalls
2011-04-06fix signal-based timers with null sigevent argumentRich Felker5-28/+19
since timer_create is no longer allocating a structure for the timer_t and simply using the kernel timer id, it was impossible to specify the timer_t as the argument to the signal handler. the solution is to pass the null sigevent pointer on to the kernel, rather than filling it in userspace, so that the kernel does the right thing. however, that precludes the clever timerid-versus-threadid encoding we were doing. instead, just assume timerids are below 1M and thread pointers are above 1M. (in perspective: timerids are sequentially allocated and seem limited to 32k, and thread pointers are at roughly 3G.)
2011-04-06fix incorrect (and conflicting on LP64 archs) types for sysv ipc msgq functionsRich Felker2-2/+2
2011-04-05fix (hopefully) statvfs breakage on x86_64 that resulted from fixing i386...Rich Felker2-2/+10
2011-04-05document more changesRich Felker1-0/+2
2011-04-05new framework to inhibit thread cancellation when neededRich Felker3-5/+17
with these small changes, libc functions which need to call functions which are cancellation points, but which themselves must not be cancellation points, can use the CANCELPT_INHIBIT and CANCELPT_RESUME macros to temporarily inhibit all cancellation.
2011-04-05add ip6 pktinfo stuff for x86_64Rich Felker1-0/+12
these defs should probably all be moved out of bits and unified...
