Update.
2004-01-14 Ulrich Drepper <drepper@redhat.com>
* configure.in: Define HAVE_Z_RELRO if the linker supports -z relro.
* config.h.in: Add entry for HAVE_Z_RELRO.
* include/libc-symbols.h: Define attribute_relro.
* elf/dl-load.c: Add attribute_relro to env_path_list, capstr, ncapstr,
max_capstrlen, and max_dirnamelen definitions.
* elf/rtld.c: Add attribute_relro to _dl_argc, _dl_argv, _dl_skip_args,
load_time, start_time, library_path, preloadlist, version_info,
any_debug.
Remove rtld_total_time. Make it a local variable. Pass pointer to
it to print_statistics. Change print_statistics accordingly.
* sysdeps/generic/dl-sysdep.c: Add attribute_relro to _dl_auxv. Use
attribute_relro instead of explicitly assigning variable to the
.data.rel.ro section for __libc_enable_secure and __libc_stack_end.
* sysdeps/generic/ldsodefs.h: Declare __libc_stack_end, _dl_argc,
_dl_argv, _dl_argv_internal with attribute_relro.
