Update.
2004-01-13 Ulrich Drepper <drepper@redhat.com>
* Makeconfig: Define relro-LDFLAGS if have-z-relro==yes. Add it to
LDFLAGS.so and LDFLAGS-rtld.
(+link): Add relro-LDFLAGS.
* Makeconfig (shlib.lds): Place __libc_subfreeres, __libc_atexit, and
__libc_thread_subfreeres sections after .jcr section.
* config.make.in: Add have-z-relro.
* configure.in: Add check for -z relro option.
* include/link.h (struct link_map): Add relro_addr and relro_size
members.
* elf/dl-load.c (_dl_map_object_from_fd): Recognize PT_GNU_RELRO.
* elf/dl-reloc.c (_dl_relocate_object): At the end, make relro
part of loaded segments read-only.
* elf/elf.h: Define PT_GNU_RELRO.
* elf/rtld.c (_dl_start): Recognize PT_GNU_RELRO of ld.so.
(dl_main): Recognize PT_GNU_RELRO of the application. Call
_dl_debug_initialize and initialize l_info[DT_DEBUG] before
relocations.
