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. --- config.make.in | 1 + 1 file changed, 1 insertion(+) (limited to 'config.make.in') diff --git a/config.make.in b/config.make.in index ae74ccf26e..d4e09d97e3 100644 --- a/config.make.in +++ b/config.make.in @@ -44,6 +44,7 @@ have-z-initfirst = @libc_cv_z_initfirst@ have-z-combreloc = @libc_cv_z_combreloc@ have-z-execstack = @libc_cv_z_execstack@ have-initfini = @libc_cv_have_initfini@ +have-z-relro = @libc_cv_z_relro@ have-Bgroup = @libc_cv_Bgroup@ need-nopic-initfini = @nopic_initfini@ with-fp = @with_fp@ -- cgit v1.2.3
