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.
