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. --- sysdeps/i386/dl-machine.h | 5 +++++ sysdeps/sh/dl-machine.h | 1 + sysdeps/x86_64/dl-machine.h | 15 ++++++++++----- 3 files changed, 16 insertions(+), 5 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/i386/dl-machine.h b/sysdeps/i386/dl-machine.h index 6f60cf3..60122c5 100644 --- a/sysdeps/i386/dl-machine.h +++ b/sysdeps/i386/dl-machine.h @@ -432,6 +432,7 @@ elf_machine_rel (struct link_map *map, const Elf32_Rel *reloc, Therefore the offset is already correct. */ if (sym != NULL) *reloc_addr = sym->st_value; + CHECK_STATIC_TLS (map, sym_map); # endif break; case R_386_TLS_TPOFF32: @@ -445,6 +446,7 @@ elf_machine_rel (struct link_map *map, const Elf32_Rel *reloc, block we subtract the offset from that of the TLS block. */ if (sym != NULL) *reloc_addr += sym_map->l_tls_offset - sym->st_value; + CHECK_STATIC_TLS (map, sym_map); # endif break; case R_386_TLS_TPOFF: @@ -457,6 +459,7 @@ elf_machine_rel (struct link_map *map, const Elf32_Rel *reloc, thread pointer. */ if (sym != NULL) *reloc_addr += sym->st_value - sym_map->l_tls_offset; + CHECK_STATIC_TLS (map, sym_map); # endif break; #endif /* use TLS */ @@ -549,6 +552,7 @@ elf_machine_rela (struct link_map *map, const Elf32_Rela *reloc, *reloc_addr = (sym == NULL ? 0 : sym_map->l_tls_offset - sym->st_value) + reloc->r_addend; + CHECK_STATIC_TLS (map, sym_map); break; case R_386_TLS_TPOFF: /* The offset is negative, forward from the thread pointer. */ @@ -558,6 +562,7 @@ elf_machine_rela (struct link_map *map, const Elf32_Rela *reloc, *reloc_addr = (sym == NULL ? 0 : sym->st_value - sym_map->l_tls_offset) + reloc->r_addend; + CHECK_STATIC_TLS (map, sym_map); break; #endif /* use TLS */ default: diff --git a/sysdeps/sh/dl-machine.h b/sysdeps/sh/dl-machine.h index 5e264d3..c6d094d 100644 --- a/sysdeps/sh/dl-machine.h +++ b/sysdeps/sh/dl-machine.h @@ -582,6 +582,7 @@ elf_machine_rela (struct link_map *map, const Elf32_Rela *reloc, *reloc_addr = ((sym == NULL ? 0 : sym_map->l_tls_offset + sym->st_value) + reloc->r_addend); + CHECK_STATIC_TLS (map, sym_map); # endif break; #endif /* use TLS */ diff --git a/sysdeps/x86_64/dl-machine.h b/sysdeps/x86_64/dl-machine.h index 740d6b7..118a4b7 100644 --- a/sysdeps/x86_64/dl-machine.h +++ b/sysdeps/x86_64/dl-machine.h @@ -428,11 +428,16 @@ elf_machine_rela (struct link_map *map, const Elf64_Rela *reloc, # ifndef RTLD_BOOTSTRAP if (sym != NULL) # endif - /* We know the offset of the object the symbol is contained in. - It is a negative value which will be added to the - thread pointer. */ - *reloc_addr = (sym->st_value + reloc->r_addend - - sym_map->l_tls_offset); + { + /* We know the offset of the object the symbol is contained in. + It is a negative value which will be added to the + thread pointer. */ + *reloc_addr = (sym->st_value + reloc->r_addend + - sym_map->l_tls_offset); +# ifndef RTLD_BOOTSTRAP + CHECK_STATIC_TLS (map, sym_map); +# endif + } break; #endif /* use TLS */ -- cgit v1.1
