2016-10-20	fix clock_nanosleep error case	Daniel Sabogal	1	-1/+3
	posix requires that EINVAL be returned if the first parameter specifies the cpu-time clock of the calling thread (CLOCK_THREAD_CPUTIME_ID). linux returns ENOTSUP instead so we handle this.
2011-04-17	overhaul pthread cancellation	Rich Felker	1	-5/+1
	this patch improves the correctness, simplicity, and size of cancellation-related code. modulo any small errors, it should now be completely conformant, safe, and resource-leak free. the notion of entering and exiting cancellation-point context has been completely eliminated and replaced with alternative syscall assembly code for cancellable syscalls. the assembly is responsible for setting up execution context information (stack pointer and address of the syscall instruction) which the cancellation signal handler can use to determine whether the interrupted code was in a cancellable state. these changes eliminate race conditions in the previous generation of cancellation handling code (whereby a cancellation request received just prior to the syscall would not be processed, leaving the syscall to block, potentially indefinitely), and remedy an issue where non-cancellable syscalls made from signal handlers became cancellable if the signal handler interrupted a cancellation point. x86_64 asm is untested and may need a second try to get it right.
2011-04-06	consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefix	Rich Felker	1	-1/+1

2011-03-19	if returning errno value directly from a syscall, we need to negate it.	Rich Felker	1	-1/+1

2011-03-19	syscall overhaul part two - unify public and internal syscall interface	Rich Felker	1	-2/+1
	with this patch, the syscallN() functions are no longer needed; a variadic syscall() macro allows syscalls with anywhere from 0 to 6 arguments to be made with a single macro name. also, manually casting each non-integer argument with (long) is no longer necessary; the casts are hidden in the macros. some source files which depended on being able to define the old macro SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall() instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL have also been changed. x86_64 has not been tested, and may need a follow-up commit to fix any minor bugs/oversights.
2011-03-10	more cancellation points: tcdrain, clock_nanosleep	Rich Felker	1	-1/+6

2011-02-19	implement the remaining clock_* interfaces	Rich Felker	1	-0/+8
