2017-10-05bfd_set_input_errorPedro Alves5-21/+48
A downside to the 2017-10-04 PR22245 fix is that bfd_set_error can now silently accept invalid errors if/when someone passes the a value of the wrong enumeration type, which previously would be caught by the -Wenum-conversion warning.

2017-10-05PR21167, relocation sections not included in groupsAlan Modra2-18/+39
This fixes a wart I've known about for years, but haven't done anything about because BFD treats relocation sections as an adjunct to the section they relocate. SHF_GROUP on the section thus implicitly applies to its relocation section(s), but it is an error that the reloc sections aren't part of the group. Like many patches to gas, this wasn't as straightforward as it could be due to a number of backends, i386, cr16 and others, removing relocs in tc_get_reloc rather than marking them as "done" earlier in md_apply_reloc. So it isn't possible for the group support to reliably detect the presence of relocs by looking at fixups earlier than write_relocs. However the group support needs to create signature symbols, and that must be done before the symbol table is frozen, before write_relocs. So split off the group sizing from elf_adjust_symtab and put it in elf_frob_file_after_relocs. bfd/ PR 21167 * elf.c (_bfd_elf_setup_sections): Don't trim reloc sections from groups. (_bfd_elf_init_reloc_shdr): Pass sec_hdr, use it to copy SHF_GROUP flag from section. (elf_fake_sections): Adjust calls. Exit immediately on failure.

Passing enum as a first argument to variadic argument function may lead to undefined behavior.

2017-10-01PR22047, Heap out of bounds read in parse_comp_unitAlan Modra2-38/+22
Like the PR22230 fix, we can allocate a buffer with an extra byte rather than letting bfd_simple_get_relocated_section_contents malloc and return a buffer. Much better than allocating another buffer afterwards.

2017-09-29Fail when string merge can't alloc memoryAlan Modra2-7/+15
I was looking at Debian bug #874674 again today, and think I might have spotted the problem. It appears that merge.c tries to cope with memory allocation failures in some circumstances, but doesn't quite manage to get everything right. This patch will make ld report memory allocation failures instead of silently not merging strings. * merge.c (merge_strings): Return FALSE on malloc failure. (_bfd_merge_sections): Return failures from record_section and merge_strings.

2017-09-26PR22209, invalid memory read in find_abstract_instance_nameAlan Modra2-15/+52
This patch adds bounds checking for DW_FORM_ref_addr die refs, and calculates them relative to the first .debug_info section. See the big comment for why calculating relative to the current .debug_info section was wrong for relocatable object files. PR 22209 * dwarf2.c (struct comp_unit): Delete sec_info_ptr field. (find_abstract_instance_name): Calculate DW_FORM_ref_addr relative to stash->info_ptr_memory, and check die_ref is within that memory. Set info_ptr_end correctly when another CU is refd. Check die_ref for DW_FORM_ref4 etc. is within CU.
2017-09-26PR22205, .debug_line file table NULL filenameAlan Modra2-22/+20
The PR22200 fuzzer testcase found one way to put NULLs into .debug_line file tables. PR22205 finds another. This patch gives up on trying to prevent NULL files in the file table and instead just copes with them. Arguably, this is better than giving up and showing no info from .debug_line. I've also fixed a case where the fairly recent DWARF5 support in handling broken DWARG could result in uninitialized memory reads, and made a small tidy.

2017-09-24PR22187, infinite loop in find_abstract_instance_nameAlan Modra2-25/+61
This patch prevents the simple case of infinite recursion in find_abstract_instance_name by ensuring that the attributes being processed are not the same as the previous call. The patch also does a little cleanup, and leaves in place some changes to the nested_funcs array that I made when I wrongly thought looping might occur in scan_unit_for_symbols. PR 22187 * dwarf2.c (find_abstract_instance_name): Add orig_info_ptr and pname param. Return status. Make name const. Don't abort, return an error. Formatting.
