From 553cc5f9ad5408fc7fb49a33417acc1446f0c548 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 21 Feb 2005 23:14:10 +0000 Subject: * sysdeps/unix/sysv/linux/libc_fatal.c: Print backtrace and memory map if requested. * debug/chk_fail.c: Request backtrace and memory map dump. * Versions.def: Add GLIBC_2.4 for libc. * debug/fgets_chk.c: New file. * debug/fgets_u_chk.c: New file. * debug/getcwd_chk.c: New file. * debug/getwd_chk.c: New file. * debug/readlink_chk.c: New file. * debug/read_chk.c: New file. * debug/pread_chk.c: New file. * debug/pread64_chk.c: New file. * debug/recv_chk.c: New file. * debug/recvfrom_chk.c: New file. * debug/Versions: Add all new functions with version GLIBC_2.4. * debug/Makefile (routines): Add fgets_chk, fgets_u_chk, read_chk, pread_chk, pread64_chk, recv_chk, recvfrom_chk, readlink_chk, getwd_chk, and getcwd_chk. 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 --- socket/bits/socket2.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 socket/bits/socket2.h (limited to 'socket/bits') diff --git a/socket/bits/socket2.h b/socket/bits/socket2.h new file mode 100644 index 0000000..bb75907 --- /dev/null +++ b/socket/bits/socket2.h @@ -0,0 +1,38 @@ +/* Checking macros for socket functions. + Copyright (C) 2005 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
