2020-01-03Mach-O: misc build adjustmentsJan Beulich2-19/+25
Oldish gcc warns about local variables shadowing outer scope ones. Additionally %lx is not (always) suitable to print the result of bfd_get_32().

2020-01-02AArch64: Set the correct ELF class for AArch64 stubs (PR/25210)Tamar Christina2-0/+10
This fixes PR 25210 by specifying the the correct ELF class for AArch64 stubs. After doing this the stub section starts behaving like a normal object file loaded from disk. That is SEC_LINKER_CREATED causes us to have to write the section manually. This flag was added as a fix for PR 24753. I believe that fix to still be correct as linker created sections don't have a size on disk and it fixes the Arm bootstrap regression. But in this case specifying the correct section class also makes the stub section not be considered by compress.c. So I'm partially revert this change so that we don't have to manage the section manually as implied by SEC_LINKER_CREATED. bfd/ChangeLog: PR 25210 PR 24753 * elfnn-aarch64.c (_bfd_aarch64_create_stub_section): Set ELF class. ld/ChangeLog: PR 25210 PR 24753 * emultempl/aarch64elf.em (elf${ELFSIZE}_aarch64_add_stub_section): Remove SEC_LINKER_CREATED. * testsuite/ld-aarch64/aarch64-elf.exp: Add erratum835769-843419. * testsuite/ld-aarch64/erratum835769-843419.d: New test.

2019-12-31asan: alpha-vms: Heap-buffer-overflowAlan Modra2-51/+53
This fixes yet more errors in the alpha-vms buffer size checks. * vms-alpha.c (_bfd_vms_slurp_eisd): Don't overflow when checking offset. Don't overflow when checking rec_size, and do allow rec_size to the end of the buffer. Ensure eisd->type can be accessed, not just the first 32 bytes. Don't call _bfd_vms_save_counted_string with zero length remaining. Fail on empty string section name. (_bfd_vms_slurp_egsd): Formatting. Catch more reads past end of record size. Correct remaining length calculation. Fail on empty string section name. Consolidate error paths.

Quite a few bfd_zalloc calls are wasting time clearing memory, and should be bfd_alloc instead. * archive.c (do_slurp_bsd_armap): Use bfd_alloc rather than bfd_zalloc when memory is all written after the call. (do_slurp_coff_armap): Likewise. Set bfd_error on ridiculously large allocations that overflow bfd_size_type. Use just one bfd_release on error exit. (_bfd_slurp_extended_name_table): Use bfd_alloc for extended_names, clear last byte rather than the entire array. Use bfd_alloc for string table. Rearrange and simplify code copying file names.
