* 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 <bits/unistd.h> for fortification. * posix/bits/unistd.h: New file. * posix/Makefile (headers): Add bits/unistd.h. * socket/sys/socket.h: Include <bits/socket2.h> 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 <jakub@redhat.com> * malloc/malloc.c (malloc_printerr): If MALLOC_CHECK_={5,7}, print the error message rather than program name. 2005-02-21 Ulrich Drepper <drepper@redhat.com>
