From 7969407a01a108298ea506e0c37c1d6b7c9d424c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 3 Feb 2002 00:31:37 +0000 Subject: Update. Change ld.so to not use functions which are exported. One cannot interpose them anyway. Use INT() to mark uses, INTDEF() to mark definitions. * include/libc-symbols.h: Define INT and INTDEF. * sysdeps/generic/ldsodefs.h: Declare _dl_debug_printf_internal, _dl_signal_error_internal, _dl_map_object_internal, _dl_map_object_deps_internal, _dl_lookup_symbol_internal, _dl_lookup_versioned_symbol_internal, _dl_relocate_object_internal, _dl_debug_state_internal, _dl_start_profile_internal, and _dl_unload_cache_internal. * include/dlfcn.h: Declare _dl_catch_error_internal. * elf/rtld.c: Use INT for calls to any of the *_internal functions above. Add INTDEF to function definitions. * elf/dl-debug.c: Likewise. * elf/dl-deps.c: Likewise. * elf/dl-dst.h: Likewise. * elf/dl-error.c: Likewise. * elf/dl-fini.c: Likewise. * elf/dl-init.c: Likewise. * elf/dl-load.c: Likewise. * elf/dl-lookup.c: Likewise. * elf/dl-misc.c: Likewise. * elf/dl-open.c: Likewise. * elf/dl-profile.c: Likewise. * elf/dl-reloc.c: Likewise. * elf/dl-runtime.c: Likewise. * elf/dl-version.c: Likewise. * elf/do-lookup.h: Likewise. * sysdeps/generic/dl-cache.c: Likewise. * sysdeps/generic/dl-sysdep.c: Likewise. * sysdeps/alpha/dl-machine.h (RTLD_START): Call _dl_init_internal instead of _dl_init. * sysdeps/arm/dl-machine.h: Likewise. * sysdeps/cris/dl-machine.h: Likewise. * sysdeps/hppa/dl-machine.h: Likewise. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/ia64/dl-machine.h: Likewise. * sysdeps/m68k/dl-machine.h: Likewise. * sysdeps/mips/dl-machine.h: Likewise. * sysdeps/mips/mips64/dl-machine.h: Likewise. * sysdeps/s390/s390-32/dl-machine.h: Likewise. * sysdeps/s390/s390-64/dl-machine.h: Likewise. * sysdeps/sh/dl-machine.h: Likewise. * sysdeps/sparc/sparc32/dl-machine.h: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise. * sysdeps/x86_64/dl-machine.h: Likewise. * sysdeps/powerpc/dl-start.S (_dl_start_user): Likewise. * elf/Versions: Don't export _dl_check_all_versions, _dl_sysdep_start, and _dl_debug_initialize. --- elf/dl-deps.c | 68 ++++++++++++++++++++++++++++++----------------------------- 1 file changed, 35 insertions(+), 33 deletions(-) (limited to 'elf/dl-deps.c') diff --git a/elf/dl-deps.c b/elf/dl-deps.c index 368ad2d..43a0bd8 100644 --- a/elf/dl-deps.c +++ b/elf/dl-deps.c @@ -59,10 +59,10 @@ openaux (void *a) { struct openaux_args *args = (struct openaux_args *) a; - args->aux = _dl_map_object (args->map, args->name, 0, - (args->map->l_type == lt_executable - ? lt_library : args->map->l_type), - args->trace_mode, 0); + args->aux = INT(_dl_map_object) (args->map, args->name, 0, + (args->map->l_type == lt_executable + ? lt_library : args->map->l_type), + args->trace_mode, 0); } static ptrdiff_t @@ -107,28 +107,28 @@ struct list \ /* DST must not appear in SUID/SGID programs. */ \ if (__libc_enable_secure) \ - _dl_signal_error (0, __str, NULL, \ - N_("DST not allowed in SUID/SGID programs")); \ + INT(_dl_signal_error) (0, __str, NULL, \ + N_("DST not allowed in SUID/SGID programs"));\ \ __newp = (char *) alloca (DL_DST_REQUIRED (l, __str, strlen (__str), \ __cnt)); \ \ - __result = DL_DST_SUBSTITUTE (l, __str, __newp, 0); \ + __result = INT(_dl_dst_substitute) (l, __str, __newp, 0); \ \ if (*__result == '\0') \ { \ /* The replacement for the DST is not known.
