Rich Felker	685e40bb09	syscall overhaul part two - unify public and internal syscall interface 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.	15 years ago
Rich Felker	dc54a7cbb9	fix errors in sigqueue (potential information leak, wrong behavior) 1. any padding in the siginfo struct was not necessarily zero-filled, so it might have contained private data off the caller's stack. 2. the uid and pid must be filled in from userspace. the previous rsyscall fix broke rsyscalls because the values were always incorrect.	15 years ago

Rich Felker	0a949ebdf0	don't fail with EINTR in sigtimedwait POSIX allows either behavior, but sigwait is not allowed to fail with EINTR, so the retry loop would have to be in one or the other anyway.	15 years ago
Rich Felker	0558683d3d	fix sigsuspend syscall	15 years ago
Rich Felker	6871fd773d	make sigaltstack work (missing macros in signal.h, error conditions)	15 years ago
Rich Felker	500c969f05	fix error handling for pthread_sigmask it must return errno, not -1, and should reject invalud values for how.	15 years ago
Rich Felker	0bed7e0acf	fix race condition in raise - just mask signals a signal handler could fork after the pid/tid were read, causing the wrong process to be signalled. i'm not sure if this is supposed to have UB or not, but raise is async-signal-safe, so it probably is allowed. the current solution is slightly expensive so this implementation is likely to be changed in the future.	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
