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/__syscall_fcntl64.c | 2 +- libc/sysdeps/linux/common/ftruncate.c | 4 ++++ libc/sysdeps/linux/common/openat.c | 15 ++++++++++++++- 3 files changed, 19 insertions(+), 2 deletions(-) (limited to 'libc') diff --git a/libc/sysdeps/linux/common/__syscall_fcntl64.c b/libc/sysdeps/linux/common/__syscall_fcntl64.c index 0c13d152f..696b1ff41 100644 --- a/libc/sysdeps/linux/common/__syscall_fcntl64.c +++ b/libc/sysdeps/linux/common/__syscall_fcntl64.c @@ -30,7 +30,7 @@ int fcntl64(int fd, int cmd, ...) arg = va_arg(list, long); va_end(list); - if (SINGLE_THREAD_P || (cmd != F_SETLKW64)) + if (SINGLE_THREAD_P || (cmd != F_SETLKW && cmd != F_SETLKW64)) return __NC(fcntl64)(fd, cmd, arg); # ifdef __NEW_THREADS oldtype = LIBC_CANCEL_ASYNC(); diff --git a/libc/sysdeps/linux/common/ftruncate.c b/libc/sysdeps/linux/common/ftruncate.c index b9a69714f..637050777 100644 --- a/libc/sysdeps/linux/common/ftruncate.c +++ b/libc/sysdeps/linux/common/ftruncate.c @@ -15,7 +15,11 @@ int ftruncate(int fd, __off_t length) { # if __WORDSIZE == 32 +# if defined(__UCLIBC_SYSCALL_ALIGN_64BIT__) + return INLINE_SYSCALL(ftruncate64, 4, fd, 0, OFF_HI_LO(length)); +# else return INLINE_SYSCALL(ftruncate64, 3, fd, OFF_HI_LO(length)); +# endif # else return ftruncate64(fd, length); # endif 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
