2018-12-18don't fail pthread_sigmask/sigprocmask on invalid how when set is nullRich Felker-1/+1
the resolution of Austin Group issue #1132 changes the requirement to fail so that it only applies when the set argument (new mask) is non-null. this change was made for consistency with the description, which specified "if set is a null pointer, the value of the argument how is not significant".

2013-03-26remove __SYSCALL_SSLEN arch macro in favor of using public _NSIGRich Felker-1/+1
the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part.
2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker-1/+1
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2012-08-09fix (hopefully) all hard-coded 8's for kernel sigset_t sizeRich Felker-2/+2
some minor changes to how hard-coded sets for thread-related purposes are handled were also needed, since the old object sizes were not necessarily sufficient. things have gotten a bit ugly in this area, and i think a cleanup is in order at some point, but for now the goal is just to get the code working on all supported archs including mips, which was badly broken by linux rejecting syscalls with the wrong sigset_t size.
2012-06-02remove implementation-reserved bits when saving signal maskRich Felker-1/+11
this fix is necessary because a program could be started with some of the implementation-reserved signals masked (e.g. due to exec having been called from a signal handler, or from a non-musl program) and then could obtain an invalid-to-use-later sigset_t as the old/saved signal mask.
2011-07-30clean up pthread_sigmask/sigprocmask dependency orderRich Felker-3/+3
it's nicer for the function that doesn't use errno to be independent, and have the other one call it. saves some time and avoids clobbering errno.
2011-03-09fix error handling for pthread_sigmaskRich Felker-0/+10
it must return errno, not -1, and should reject invalud values for how.
