Update.
* posix/unistd.h: Move declaration of __libc_enable_secure to... * include/unistd.h: ...here. * elf/dl-open.c (dl_open_worker): If DST is used in SUID program punt. * elf/dl-deps.c (expand_dst): Likewise. * elf/dynamic-link.h: Set DT_SYMBOLIC, DT_TEXTREL, and DT_BIND_NOW based on DT_FLAGS value. * elf/do-lookup.h: Remove reference_name parameter, add undef_map. Add test for symbols marked STV_HIDDEN. * elf/dl-lookup.c (_dl_lookup_symbol): Remove reference_name parameter, add undef_map. Compute reference_name locally. Update call to do_lookup. (_dl_lookup_symbol_skip): Likewise. (_dl_lookup_versioned_symbol): Likewise. (_dl_lookup_versioned_symbol_skip): Likewise. * elf/dl-libc.c: Update call to _dl_lookup_*symbol. * elf/dl-runtime.c: Likewise. * elf/dl-sym.c: Likewise. * elf/dl-symbol.c: Likewise. * elf/ldsodefs.h: Adjust prototypes. * elf/dl-reloc.c (RESOLV): Add test for STV_PROTECTED flag set and handle appropriately. Add comment about DT_TEXTREL. * elf/dl-runtime.c: Likewise.
