Rich Felker	98e02144da	use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit code	15 years ago
Rich Felker	4b1244a0bf	implement the remaining clock_* interfaces	15 years ago
Rich Felker	19eb13b9a4	race condition fix: block all signals before decrementing thread count the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals.	15 years ago
Rich Felker	a49c119276	prevent sigprocmask/pthread_sigmask from blocking implementation signals this code was wrongly disabled because the old version was trying to be too clever and didn't work. replaced it with a simple version for now.	15 years ago
Rich Felker	fb11b6b85e	make pthread_exit run dtors for last thread, wait to decrement thread count	15 years ago
Rich Felker	69ecbd0f31	make mktemp match the historic behavior, and update functions that use it the historic mktemp is supposed to blank the template string on failure, rather than returning 0. just zero the first character so that mkstemp and mkdtemp can still retry with O(1) space requirement.	15 years ago
Rich Felker	2e6239dd06	fix major bug created from copying mkdtemp logic	15 years ago
Rich Felker	095a5ae6f2	add syscall wrappers for inotify	15 years ago
Rich Felker	cc2a8228fa	cleanup cruft left from when kernel and user time_t disagreed	15 years ago
Rich Felker	e9417fffb3	add pthread_atfork interface note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time.	15 years ago
Rich Felker	446b4207cc	major improvements to temp file name generator use current time in nanoseconds and some potentially-random (if aslr is enabled) pointer values for the initial tempfile name generation, and step via a cheap linear prng on collisions. limit the number of retry attempts to prevent denial of service attacks even if an attacker can guess the filenames.	15 years ago
Rich Felker	3e9e30166f	reformat mkstemp like mkdtemp this is cleaner and makes it easy to impose a limit on the number of retries later if it seems desirable to do so.	15 years ago
Rich Felker	d5ca067c7b	add portable lchown (trivial to support and a few ancient things want it..)	15 years ago
Rich Felker	e882756311	reorganize pthread data structures and move the definitions to alltypes.h this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.	15 years ago
Rich Felker	187fe29d5b	make daemon try the operations that might fail before fork rather than after	15 years ago
Rich Felker	19e35c500b	daemon should check for failures and return -1	15 years ago
Rich Felker	b24bc15f5c	don't compare elements with themselves during qsort. this is actually a workaround for a bug in gcc, whereby it asserts inequality of the keys being compared...	15 years ago
Rich Felker	5cbd76c6b0	fix printf %n specifier - missing breaks had it clobbering memory	15 years ago
Rich Felker	e3657ba599	patch by njk, simplifies thread register initialization for x86_64 It's not necessary to save any registers on the stack across syscall in x86_64 __set_thread_area. Don't waste cycles or bytes on it.	15 years ago
Rich Felker	22cd9cae81	patch from njk: make x86_64 __uniclone branchless.	15 years ago
Rich Felker	bad481266e	fix compile failure: legacy cuserid needs to define feature test	15 years ago
Rich Felker	9b235e8374	remove standalone syscall cruft this was originally written for an early draft of the library where non-standard functions would reside in a static library separate from the shared libc.so, which would implement a pure standard. the idea was not to depend on an implementation-dependent __syscall_ret function in the main libc. but it turned out to be better to put everything in a single library for both static and dynamic linking uses, and thus the (incomplete) remnants of this feature were just enlarging the source and binary.	15 years ago
Nicholas J. Kain	1e12632591	Port musl to x86-64. One giant commit!	15 years ago

Rich Felker	2cdfb7ca26	cleaning up syscalls in preparation for x86_64 port - hide all the legacy xxxxxx32 name cruft in syscall.h so the actual source files can be clean and uniform across all archs. - cleanup llseek/lseek and mmap2/mmap handling for 32/64 bit systems - alternate implementation for nice if the target lacks nice syscall	15 years ago
