2022-03-03PowerPC64 DT_RELR relative reloc addressesAlan Modra1-49/+76
Section addresses can change between ppc64_elf_size_stubs and ppc64_elf_build_stubs due to .eh_frame editing. The idea of stashing r_offset final addresses calculated in ppc64_elf_size_stubs for use by ppc64_elf_build_stubs was never a good idea. Instead, we need to keep section/offset pairs. * elf64-ppc.c (struct ppc_link_hash_table): Delete relr_addr. Add relr section/offset array. (append_relr_off): Rewrite. Update all callers. (sort_relr): New function. (ppc64_elf_size_stubs): Adjust to suit new relative reloc stash. (ppc64_elf_build_stubs): Likewise.

Since commit e601909a3287bf541c6a7d82214bb387d2c76d82 ("RISC-V: Support to parse the multi-letter prefix in the architecture string.") changed so that all prefixed extensions are parsed in single riscv_parse_prefixed_ext call, a "while" loop on riscv_parse_subset is no longer required. bfd/ChangeLog: * elfxx-riscv.c (riscv_parse_subset): Remove unnecessary loop.

2022-02-23RISC-V: PR28733, add missing extension info to 'unrecognized opcode' errorPatrick O'Neill2-0/+97
Currently we report errors as "unrecognized opcode `fence.i'" when the opcode isn't part of the selected extensions. This patch expands that error message to include the missing extension information. For example, now the error message would be "unrecognized opcode `fence.i', extension `zifencei' required". If the opcode is not a part of any extension, the error message reverts to "unrecognized opcode `<op statement>'".

2022-02-16What to do when sh_addralign isn't a power of twoAlan Modra1-6/+7
BFD generally doesn't handle anything but a power of two section alignment, and ELF sh_addralign is required to be an integral power of two (or zero) by the ELF spec. Of course this is ignored by fuzzers, and because bfd_log2 rounds up, we can end up with alignment_power being 32 on a 32-bit object or 64 on a 64-bit object. That then triggers ubsan warnings in places like bfd_update_compression_header where we want to convert from alignment_power back to an alignment. I suppose we could reject object files that have non-compliant sh_addralign, but I think it's also reasonable to use the greatest power of two divisor of sh_addralign, ie. the rightmost 1 bit. * elf.c (_bfd_elf_make_section_from_shdr): Use greatest power of two divisor of sh_addralign.

2022-02-11x86: Disallow invalid relocation against protected symbolH.J. Lu4-4/+53
I am checking this into master and will backport it to 2.38 branch. H.J ---- On x86, GCC 12 supports -mno-direct-extern-access to enable canonical reference to protected function and disable copy relocation. With -mno-direct-extern-access, the canonical protected function symbols must be accessed via canonical reference and the protected data symbols in shared libraries are non-copyable. Under glibc 2.35, non-canonical reference to the canonical protected function will get the run-time error: ./y: internal_f: ./libfoo.so: non-canonical reference to canonical protected function and copy relocations against the non-copyable protected symbols will get the run-time error: ./x: internal_i: ./libfoo.so: copy relocation against non-copyable protected symbol Update x86 linker to disallow non-canonical reference to the canonical protected function: ld: plt.o: non-canonical reference to canonical protected function `internal_f' in libfoo.so ld: failed to set dynamic section sizes: bad value and copy relocation against the non-copyable protected symbol: ld: main.o: copy relocation against non-copyable protected symbol `internal_i' in libfoo.so at link-time. bfd/ PR ld/28875 * elf-properties.c (_bfd_elf_parse_gnu_properties): Don't skip shared libraries for GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS. * elf32-i386.c (elf_i386_scan_relocs): Disallow non-canonical reference to canonical protected function. * elf64-x86-64.c (elf_x86_64_scan_relocs): Likewise. * elfxx-x86.c (elf_x86_allocate_dynrelocs): Don't allow copy relocation against non-copyable protected symbol. ld/ PR ld/28875 * testsuite/ld-i386/i386.exp: Check non-canonical reference to canonical protected function and check copy relocation against non-copyable protected symbol. * testsuite/ld-i386/pr21997-1.err: New file. * testsuite/ld-i386/pr28875.err: Likewise. * testsuite/ld-i386/pr28875a.c: Likewise. * testsuite/ld-i386/pr28875b.c: Likewise. * testsuite/ld-x86-64/pr21997-1a.err: Updated. * testsuite/ld-x86-64/pr21997-1b.err: Likewise. * testsuite/ld-x86-64/pr28875-data.err: New file. * testsuite/ld-x86-64/pr28875-func.err: Likewise. * testsuite/ld-x86-64/x86-64.exp: Check non-canonical reference to canonical protected function and check copy relocation against non-copyable protected symbol.
