* sysdeps/generic/ldsodefs.h (DL_LOOKUP_GSCOPE_LOCK): New definition.
* elf/dl-runtime.c (_dl_fixup, _dl_profile_fixup): Or in DL_LOOKUP_GSCOPE_LOCK into flags after THREAD_GSCOPE_SET_FLAG (). * elf/dl-sym.c (do_sym): Likewise. * include/link.h (struct link_map): Add l_serial field. * elf/dl-object.c (_dl_new_object): Initialize l_serial. * elf/dl-lookup.c (add_dependency): Add flags argument. Remember map->l_serial, if DL_LOOKUP_GSCOPE_LOCK is among flags, use THREAD_GSCOPE_RESET_FLAG before and THREAD_GSCOPE_SET_FLAG after __rtld_lock_lock_recursive (GL(dl_load_lock)) to avoid deadlock. Don't dereference map until it has been found on some list. If map->l_serial changed, return -1.
