From 7a1147946ecd5fe962e2959afe69c25c7a553672 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 15 Jun 2003 21:22:26 +0000 Subject: Update. 2003-06-15 Ulrich Drepper Fix cancellation point handling wrt exception based cleanup. * io/Makefile: Compile fcntl.c, poll.c, and lockf.c with exceptions. * misc/Makefile: Compile pselect.c, readv.c, writev.c, and usleep.c with exceptions. * posix/Makefile: Compile pread.c, pread64.c, pwrite.c, pwrite64.c, sleep.c, wait.c, waitid.c, and waitpid.c with exceptions. * rt/Makefile: Compile aio_suspend.c and clock_nanosleep.c with exceptions. * signal/Makefile: Compile sigpause.c, sigsuspend.c, sigtimedwait.c, sigwait.c, and sigwaitinfo.c with exceptions. * stdlib/Makefile: Compile system.c with exceptions. * sysvipc/Makefile: Compile msgrcv.c and msgsnd.c with exceptions. * termios/Makefile: Compile tcdrain.c with exceptions. * sysdeps/generic/lockf.c: Add comment explaining the cancellation situation. * sysdeps/generic/pselect.c: Likewise. * sysdeps/posix/sigpause.c: Likewise. * sysdeps/posix/system.c: Likewise. * sysdeps/posix/waitid.c: Likewise. * sysdeps/unix/sysv/linux/sleep.c: Likewise. * sysdeps/unix/sysv/linux/usleep.c: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Major rewrite of INTERNAL_SYSCALL to not use push inside asm statement so that unwind info is correct around the syscall. * sysdeps/unix/clock_nanosleep.c: Add cancellation support. * sysdeps/unix/sysv/linux/clock_nanosleep.c: Likewise. --- sysdeps/unix/sysv/linux/clock_nanosleep.c | 22 +++++++++++++++++++--- 1 file changed, 19 insertions(+), 3 deletions(-) (limited to 'sysdeps/unix/sysv/linux/clock_nanosleep.c') diff --git a/sysdeps/unix/sysv/linux/clock_nanosleep.c b/sysdeps/unix/sysv/linux/clock_nanosleep.c index ceb3801eb9..2a3dd411a1 100644 --- a/sysdeps/unix/sysv/linux/clock_nanosleep.c +++ b/sysdeps/unix/sysv/linux/clock_nanosleep.c @@ -18,7 +18,7 @@ #include -#include +#include #include "kernel-features.h" @@ -32,7 +32,18 @@ clock_nanosleep (clockid_t clock_id, int flags, const struct timespec *req, INTERNAL_SYSCALL_DECL (err); int r; - r = INTERNAL_SYSCALL (clock_nanosleep, err, 4, clock_id, flags, req, rem); + if (SINGLE_THREAD_P) + r = INTERNAL_SYSCALL (clock_nanosleep, err, 4, clock_id, flags, req, rem); + else + { + int oldstate = LIBC_CANCEL_ASYNC (); + + r = INTERNAL_SYSCALL (clock_nanosleep, err, 4, clock_id, flags, req, + rem); + + LIBC_CANCEL_RESET (oldstate); + } + return (INTERNAL_SYSCALL_ERROR_P (r, err) ?
