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. --- elf/do-lookup.h | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) (limited to 'elf/do-lookup.h') diff --git a/elf/do-lookup.h b/elf/do-lookup.h index 147560bd32..f83b13ccf3 100644 --- a/elf/do-lookup.h +++ b/elf/do-lookup.h @@ -29,10 +29,10 @@ found the symbol, the value 0 if nothing is found and < 0 if something bad happened. */ static inline int -FCT (const char *undef_name, unsigned long int hash, - const ElfW(Sym) *ref, struct sym_val *result, - struct r_scope_elem *scope, size_t i, const char *reference_name, - ARG struct link_map *skip, int reloc_type) +FCT (const char *undef_name, struct link_map *undef_map, + unsigned long int hash, const ElfW(Sym) *ref, struct sym_val *result, + struct r_scope_elem *scope, size_t i, ARG struct link_map *skip, + int reloc_type) { struct link_map **list = scope->r_list; size_t n = scope->r_nlist; @@ -154,7 +154,12 @@ FCT (const char *undef_name, unsigned long int hash, sym = num_versions == 1 ? versioned_sym : NULL; #endif - if (sym != NULL) + if (sym != NULL + /* Don't allow binding if the symbol is hidden.
