2017-04-10PR21287, Inconsistent section type for .init_array and .init_array.42Alan Modra2-10/+17
PR21287 notes that .init_array is correctly given a type of SHT_INIT_ARRAY while .init_array.nnn gets SHT_PROGBITS. This patch fixes that problem, and properly drops warnings from the compiler that would cause the testsuite to fail. My a44d0bd78 change to check ld_compile status, necessary to pick up compile errors, also meant warnings were not ignored. bfd/ PR 21287 * elf.c (special_sections_f): Match .fini_array and .fini_array.*.

2017-04-04Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXXH.J. Lu2-2/+73
Mark an ALLOC section, which should be placed in special memory area, with SHF_GNU_MBIND. Its sh_info field indicates the special memory type. GNU_MBIND section names start with ".mbind" so that they are placed as orphan sections by linker. All input GNU_MBIND sections with the same sh_type, sh_flags and sh_info are placed in one output GNU_MBIND section. In executable and shared object, create a GNU_MBIND segment for each GNU_MBIND section and its segment type is PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is aligned at page boundary. The assembler syntax: .section .mbind.foo,"adx",%progbits ^ 0: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.foo,"adx",%progbits,0x1 ^ 1: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2 ^ 2: Special memory type. | 'd' for SHF_GNU_MBIND. bfd/ * elf.c (get_program_header_size): Add a GNU_MBIND segment for each GNU_MBIND section and align GNU_MBIND section to page size.

2017-03-18DT_TEXTREL vs IFUNCAlan Modra3-22/+109
If you should somehow link non-pic objects into a PIE or shared library, resulting in an object with DT_TEXTREL (text relocations) set, and your executable or shared library also contains GNU indirect functions, then you're in trouble. To apply dynamic relocations ld.so will make the text segment writable. On most systems this will make the text segment non-executable, which will then result in a segfault when ld.so tries to run ifunc resolvers when applying relocations against ifuncs. This patch teaches PowerPC ld to detect the situation, and warn. * elf64-ppc.c (struct ppc_link_hash_table): Add local_ifunc_resolver and maybe_local_ifunc_resolver. (ppc_build_one_stub): Set flags on emitting dynamic relocation to ifunc. (ppc64_elf_relocate_section): Likewise. (ppc64_elf_finish_dynamic_symbol): Likewise. (ppc64_elf_finish_dynamic_sections): Error on DT_TEXTREL with local dynamic relocs to ifuncs. * elf32-ppc.c (struct ppc_elf_link_hash_table): Add local_ifunc_resolver and maybe_local_ifunc_resolver. (ppc_elf_relocate_section): Set flag on emitting dynamic relocation to ifuncs. (ppc_elf_finish_dynamic_symbol): Likewise. (ppc_elf_finish_dynamic_sections): Error on DT_TEXTREL with local dynamic relocs to ifuncs.
