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 --- debug/chk_fail.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'debug/chk_fail.c') diff --git a/debug/chk_fail.c b/debug/chk_fail.c index 6921ca4..0cfca29 100644 --- a/debug/chk_fail.c +++ b/debug/chk_fail.c @@ -28,7 +28,7 @@ __chk_fail (void) { /* The loop is added only to keep gcc happy. */ while (1) - __libc_message (1, "*** buffer overflow detected ***: %s terminated\n", + __libc_message (2, "*** buffer overflow detected ***: %s terminated\n", __libc_argv[0] ?: ""); } libc_hidden_def (__chk_fail) -- cgit v1.1
