Plus appropriate CFLAGS definitions. * debug/tst-chk1.c: Add more tests. * libio/bits/stdio2.h: Add macros for fgets and fgets_unlocked. * include/stdio.h: Declare __fgets_chk and __fgets_unlocked_chk. * posix/unistd.h: Include for fortification. * posix/bits/unistd.h: New file. * posix/Makefile (headers): Add bits/unistd.h. * socket/sys/socket.h: Include for fortification. * socket/bits/socket2.h: New file. * socket/Makefile (headers): Add bits/socket2.h. * string/bits/string3.h: Extend memset macro to check for zero 3rd parameter and use __memset_zero_constant_len_parameter in that case. * sysdeps/generic/memset_chk.c: Add __memset_zero_constant_len_parameter alias and linker warning. * debug/Versions: Add __memset_zero_constant_len_parameter to libc with version GLIBC_2.4. * sysdeps/generic/bits/types.h: Don't unnecessarily use __extension__ in __STD_TYPE definition. 2005-02-21 Jakub Jelinek * malloc/malloc.c (malloc_printerr): If MALLOC_CHECK_={5,7}, print the error message rather than program name. 2005-02-21 Ulrich Drepper --- posix/unistd.h | 1 + 1 file changed, 1 insertion(+) (limited to 'posix/unistd.h') diff --git a/posix/unistd.h b/posix/unistd.h index 97e28fc70b..d6cd152b46 100644 --- a/posix/unistd.h +++ b/posix/unistd.h @@ -1046,6 +1046,7 @@ extern void swab (__const void *__restrict __from, void *__restrict __to, extern char *ctermid (char *__s) __THROW __nonnull ((1)); #endif + /* Define some macros helping to catch buffer overflows. */ #if __USE_FORTIFY_LEVEL > 0 && !defined __cplusplus # include -- cgit v1.2.3
