From 7b1c4fa9bd8df64c8002ea4e613c8952bdfefbdd Mon Sep 17 00:00:00 2001 From: "han_mao@c-sky.com" Date: Thu, 13 Dec 2018 09:37:12 +0800 Subject: several patches for uclibc ng I've got several patches to fix ltp/openmp/uclibc-ng-test testcase fail on c-sky. - fix a ltp testcase. - fix the problem that pthread creat will fail when libomp is linked before libc, the variable pagesize is not init. - fix tst-cancel4 and tst-cancel16. tst-cancelx4 and tst-cancelx16 still fail with this patch applied, cleanup handler is not called for open/creat/fcntl, seems some thing wrong with unwind, I haven't check the rootcause yet. --- libc/sysdeps/linux/common/openat.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'libc/sysdeps/linux/common/openat.c') diff --git a/libc/sysdeps/linux/common/openat.c b/libc/sysdeps/linux/common/openat.c index f71567cdc..62451df4c 100644 --- a/libc/sysdeps/linux/common/openat.c +++ b/libc/sysdeps/linux/common/openat.c @@ -9,6 +9,7 @@ #include #include #include +#include #ifdef __NR_openat # define __NR___syscall_openat __NR_openat @@ -16,13 +17,25 @@ static __inline__ _syscall4(int, __syscall_openat, int, fd, const char *, file, int __openat(int fd, const char *file, int o_flag, ...) { +#ifdef __NEW_THREADS + int oldtype, result; +#endif va_list ap; mode_t mode; va_start(ap, o_flag); mode = va_arg(ap, int); va_end(ap); - return __syscall_openat(fd, file, o_flag, mode); + + if (SINGLE_THREAD_P) + return __syscall_openat(fd, file, o_flag, mode); + +#ifdef __NEW_THREADS + oldtype = LIBC_CANCEL_ASYNC (); + result = __syscall_openat(fd, file, o_flag, mode); + LIBC_CANCEL_RESET (oldtype); + return result; +#endif } strong_alias_untyped(__openat,openat) -- cgit v1.2.3
