From 2430d57a13f4f10312e13c58962cd9104e6428fd Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 17 Oct 2002 12:10:17 +0000 Subject: * elf/dl-load.c (_dl_map_object_from_fd): Don't check DF_STATIC_TLS. * elf/dl-reloc.c (_dl_relocate_object: CHECK_STATIC_TLS): New macro to signal error if an IE-model TLS reloc resolved to a dlopen'd module. * sysdeps/i386/dl-machine.h (elf_machine_rel, elf_machine_rela): Call it after performing TPOFF relocs. * sysdeps/x86_64/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/sh/dl-machine.h (elf_machine_rela): Likewise. * elf/dl-conflict.c (CHECK_STATIC_TLS): New macro (no-op). * elf/dl-close.c (remove_slotinfo): Change asserts so as not to crash when closing a partially-initialized object. * elf/dl-load.c (_dl_map_object_from_fd) [! USE_TLS]: Call lose instead of _dl_fatal_printf when we see PT_TLS. --- elf/dl-reloc.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'elf/dl-reloc.c') diff --git a/elf/dl-reloc.c b/elf/dl-reloc.c index 37d1ee019f..d6db62b11e 100644 --- a/elf/dl-reloc.c +++ b/elf/dl-reloc.c @@ -159,6 +159,15 @@ _dl_relocate_object (struct link_map *l, struct r_scope_elem *scope[], l->l_lookup_cache.value = _lr; })) \ : l->l_addr) +#define CHECK_STATIC_TLS(map, sym_map) \ + do { \ + if (__builtin_expect ((sym_map)->l_tls_offset == 0, 0)) \ + { \ + errstring = N_("shared object cannot be dlopen()ed"); \ + INTUSE(_dl_signal_error) (0, (map)->l_name, NULL, errstring); \ + } \ + } while (0) + #include "dynamic-link.h" ELF_DYNAMIC_RELOCATE (l, lazy, consider_profiling); -- cgit v1.2.3
