Update.
2004-01-22 Jakub Jelinek <jakub@redhat.com>
* elf/dl-reloc.c (_dl_relocate_object): Move PT_GNU_RELRO protection
into...
(_dl_protect_relro): New routine.
* sysdeps/generic/ldsodefs.h (_dl_protect_relro): New prototype.
* elf/rtld.c (_dl_start_final): Copy l_relro_addr and l_relro_size
from bootstrap_map.
(_dl_main): Don't set GL(_dl_loaded)->l_relro_{addr,size} here.
Call _dl_protect_relro for libraries if prelinking.
