From ccc7b4c3a17ade90de71e1e0f44deebbffd646e6 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 26 Mar 2013 23:07:31 -0400 Subject: remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG 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. --- src/thread/synccall.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/thread/synccall.c') diff --git a/src/thread/synccall.c b/src/thread/synccall.c index dc59863f..8c825ace 100644 --- a/src/thread/synccall.c +++ b/src/thread/synccall.c @@ -62,7 +62,7 @@ void __synccall(void (*func)(void *), void *ctx) __inhibit_ptc(); __syscall(SYS_rt_sigprocmask, SIG_BLOCK, SIGALL_SET, - &oldmask, __SYSCALL_SSLEN); + &oldmask, _NSIG/8); sem_init(&chaindone, 0, 0); sem_init(&chainlock, 0, 1); @@ -95,7 +95,7 @@ void __synccall(void (*func)(void *), void *ctx) __libc_sigaction(SIGSYNCCALL, &sa, 0); __syscall(SYS_rt_sigprocmask, SIG_SETMASK, - &oldmask, 0, __SYSCALL_SSLEN); + &oldmask, 0, _NSIG/8); __release_ptc(); } -- cgit v1.2.1
