Rich Felker	8b61c81693	alternate name for syslog.h	15 years ago
Rich Felker	f93de08ca4	uncomment IP_PKTINFO this was a hack leftover from testing before the initial check-in to git.	15 years ago
Rich Felker	39e48531ef	support the nonstandard err.h interfaces note that unlike the originals, these do not print the program name/argv[0] because we have not saved it anywhere. this could be changed in __libc_start_main if desired.	15 years ago
Rich Felker	25ce7621e0	release notes for next bugfix release	15 years ago
Rich Felker	16675df793	fix misaligned read on early string termination in strchr this could actually cause rare crashes in the case where a short string is located at the end of a page and the following page is not readable, and in fact this was seen in gcc compiling certain files.	15 years ago
Rich Felker	2f3d02cd83	fix overflow in printf %N$ argument handling	15 years ago
Rich Felker	f9569662c0	fix various floating point rounding and formatting errors in *printf	15 years ago
Rich Felker	bd1f6eba8c	release notes for 0.7.6 bugfix release	15 years ago
Rich Felker	b761bd19aa	fix rare but nasty under-allocation bug in malloc with large requests the bug appeared only with requests roughly 2sizeof(size_t) to 4sizeof(size_t) bytes smaller than a multiple of the page size, and only for requests large enough to be serviced by mmap instead of the normal heap. it was only ever observed on 64-bit machines but presumably could also affect 32-bit (albeit with a smaller window of opportunity).	15 years ago
Rich Felker	98c5583ad5	simplify vdprintf implementation greatly based on recent vfprintf changes since vfprintf will provide a temporary buffer in the case where the target FILE has a zero buffer size, don't bother setting up a real buffer for vdprintf. this also allows us to skip the call to fflush since we know everything will be written out before vfprintf returns.	15 years ago
Rich Felker	bd57e2b43a	use a local temp buffer for unbuffered streams in vfprintf this change makes it so most calls to fprintf(stderr, ...) will result in a single writev syscall, as opposed to roughly 2*N syscalls (and possibly more) where N is the number of format specifiers. in principle we could use a much larger buffer, but it's best not to increase the stack requirements too much. most messages are under 80 chars.	15 years ago
Rich Felker	5600088d38	fix nl_langinfo to actually use the existing, correct internal version	15 years ago
Rich Felker	3910e93340	make ualarm actually work (obsolete function removed from SUS)	15 years ago
Rich Felker	e898a79053	fix various bugs in strtold: 0e10000000000000000000000000000000 was setting ERANGE exponent char e/p was considered part of the match even if not followed by a valid decimal value "1e +10" was parsed as "1e+10" hex digits were misinterpreted as 0..5 instead of 10..15	15 years ago
Rich Felker	c68b26369e	fix serious bug in strchr - char signedness search for bytes with high bit set was giving (potentially dangerous) wrong results. i've tested, cleaned up, and hopefully sped up this function now.	15 years ago
Rich Felker	2155afd73e	prototype getdtablesize (nonstandard function)	15 years ago
Rich Felker	1db283bf19	add setresuid/setresgid functions (nonstandard)	15 years ago
Rich Felker	7fd3995282	pthread_create need not set errno	15 years ago
Rich Felker	7e795ca7ed	fix statvfs syscalls (missing size argument)	15 years ago
Rich Felker	66def4e776	block all signals during rsyscall otherwise a signal handler could see an inconsistent and nonconformant program state where different threads have different uids/gids.	15 years ago
Rich Felker	1ad049b7b6	fix race condition in rsyscall handler the problem: there is a (single-instruction) race condition window between a thread flagging itself dead and decrementing itself from the thread count. if it receives the rsyscall signal at this exact moment, the rsyscall caller will never succeed in signalling enough flags to succeed, and will deadlock forever. in previous versions of musl, the about-to-terminate thread masked all signals prior to decrementing the thread count, but this cost a whole syscall just to account for extremely rare races. the solution is a huge hack: rather than blocking in the signal handler if the thread is dead, modify the signal mask of the saved context and return in order to prevent further signal handling by the dead thread. this allows the dead thread to continue decrementing the thread count (if it had not yet done so) and exiting, even while the live part of the program blocks for rsyscall.	15 years ago
Rich Felker	c9b2d8016f	don't trust siginfo in rsyscall handler for some inexplicable reason, linux allows the sender of realtime signals to spoof its identity. permission checks for sending signals should limit the impact to same-user processes, but just to be safe, we avoid trusting the siginfo structure and instead simply examine the program state to see if we're in the middle of a legitimate rsyscall.	15 years ago
Rich Felker	6e9ed66d0d	timer threads should sleep and stay asleep... a long time	15 years ago
Rich Felker	6f1414e102	revert to deleting kernel-level timer from cancellation handler this is necessary in order to avoid breaking timer_getoverrun in the last run of the timer event handler, if it has not yet finished.	15 years ago
Rich Felker	f01d351842	simplify calling of timer signal handler	15 years ago
Rich Felker	06baa2b56c	d_fileno alias for d_ino in dirent this is nonstandard but since POSIX reserved d_ prefix in dirent.h we might as well define it unconditionally. some programs depend on it.	15 years ago
Rich Felker	537d33d334	simplify pthread tsd key handling	15 years ago
Rich Felker	fd80cfa00b	omit pthread tsd dtor code if tsd is not used	15 years ago
Rich Felker	8de03e1a90	don't disable seeking after first seek failure this could cause problems if the application uses dup2(fd,fileno(f)) to redirect, and the old fd was not seekable but the new fd is.	15 years ago
Rich Felker	9a909fcd91	apparently fseek should not set the error flag on failed seek	15 years ago
Rich Felker	d1c24ac4ec	update release notes	15 years ago
Rich Felker	bf8785825a	avoid over-allocation of brk on first malloc if init_malloc returns positive (successful first init), malloc will retry getting a chunk from the free bins rather than expanding the heap again. also pass init_malloc a hint for the size of the initial allocation.	15 years ago
Rich Felker	952987a0cb	reorganize the __libc structure for threaded performance issues we want to keep atomically updated fields (locks and thread count) and really anything writable far away from frequently-needed function pointers. stuff some rarely-needed function pointers in between to pad, hopefully up to a cache line boundary.	15 years ago
Rich Felker	4ae5e811f8	simplify setting result on thread cancellation	15 years ago
Rich Felker	6c16d3e98a	use bss instead of mmap for main thread's pthread thread-specific data this simplifies code and removes a failure case	15 years ago
Rich Felker	5243e5f160	remove obsolete and useless useconds_t type	15 years ago
Rich Felker	3bb00f4579	somehow timespec tv_nsec had the wrong type on x86_64... fixed	15 years ago
