Since ns32k-netbsd is as yet not removed, just marked obsolete, the target should still be accepted with --enable-obsolete. I also enabled ns32k-openbsd in ld since there doesn't seem to be a good reason why that target is not supported there but is elsewhere. bfd/ * config.bfd: Allow ns32k-netbsd. ld/ * configure.tgt: Allow ns32k-openbsd.

2021-08-11Deprecate a.out support for NetBSD targets.John Ericson4-932/+964
As discussed previously, a.out support is now quite deprecated, and in some cases removed, in both Binutils itself and NetBSD, so this legacy default makes little sense. `netbsdelf*` and `netbsdaout*` still work allowing the user to be explicit about there choice. Additionally, the configure script warns about the change as Nick Clifton requested. One possible concern was the status of NetBSD on NS32K, where only a.out was supported. But per [1] NetBSD has removed support, and if it were to come back, it would be with ELF. The binutils implementation is therefore marked obsolete, per the instructions in the last message. With that patch and this one applied, I have confirmed the following: --target=i686-unknown-netbsd --target=i686-unknown-netbsdelf builds completely --target=i686-unknown-netbsdaout properly fails because target is deprecated. --target=vax-unknown-netbsdaout builds completely except for gas, where the target is deprecated.

2021-08-11PR28163, Segment fault in function rl78_special_relocAlan Modra1-365/+360
Relocation offset checks were completely missing in the rl78 backend, allowing a relocation to write over memory anywhere. This was true for rl78_special_reloc, a function primarily used when applying debug relocations, and in rl78_elf_relocate_section used by the linker. This patch fixes those problems by correcting inaccuracies in the relocation howtos, then uses those howtos to sanity check relocation offsets before applying relocations. In addition, the patch implements overflow checking using the howto information rather than the ad-hoc scheme implemented in relocate_section. I implemented the overflow checking in rl78_special_reloc too. * elf32-rl78.c (RL78REL, RL78_OP_REL): Add mask parameter. (rl78_elf_howto_table): Set destination masks. Correct size and bitsize of DIR32_REV. Correct complain_on_overflow for many relocs as per tests in relocate_section. Add RH_SFR. Correct bitsize for RH_SADDR. Set size to 3 and bitsize to 0 for all OP relocs. (check_overflow): New function. (rl78_special_reloc): Check that reloc address is within section. Apply relocations using reloc howto. Check for overflow. (RANGE): Delete. (rl78_elf_relocate_section): Sanity check r_offset. Perform overflow checking using reloc howto.

2021-08-07PR28176, rl78 complex reloc divide by zeroAlan Modra1-129/+154
This is a bit more than just preventing the divide by zero. Most of the patch is tidying up error reporting, so that for example, linking an object file with a reloc stack underflow produces a linker error rather than just displaying a message that might be ignored. PR 28176 * elf32-rl78.c (RL78_STACK_PUSH, RL78_STACK_POP): Delete. (rl78_stack_push, rl78_stack_pop): New inline functions. (rl78_compute_complex_reloc): Add status and error message params.

2021-08-06bfd_reloc_offset_in_range overflowAlan Modra1-1/+1
This patch is more about the style of bounds checking we ought to use, rather than a real problem. An overflow of "octet + reloc_size" can only happen with huge sections which would certainly cause out of memory errors. * reloc.c (bfd_reloc_offset_in_range): Avoid possible overflow.

2021-08-04PR28162, segment fault in mips_elf_assign_gpAlan Modra2-7/+7
For the testcase in the PR, _bfd_mips_elf32_gprel16_reloc is passed a NULL output_bfd. As expected for reloc special functions if called by objdump or when final linking. The function attempts to find the output by output_bfd = symbol->section->output_section->owner; That makes some sense, since when handling a gp-relative reloc we need the relevant gp to which the symbol is relative. Possibly the gp value can be one for a shared library? But that doesn't seem useful or supported by the various abi docs and won't work as written. Symbols defined in shared libraries have section->output_section NULL, and what's more the code in mips_elf_assign_gp isn't set up to look at shared library symbols. Also, if the symbol is a SHN_ABS one the owner of *ABS* section is NULL, which will result in the testcase segfault. The only gp to which an absolute symbol can be relative is the linker output bfd when linking, or the input bfd when not. This patch arranges to do that for all gp-relative reloc symbols. * elf32-mips.c (_bfd_mips_elf32_gprel16_reloc): Don't use the section symbol to find the output bfd, use input_section. (mips_elf_gprel32_reloc, mips16_gprel_reloc): Likewise. * elf64-mips.c (mips_elf64_gprel16_reloc): Likewise. (mips_elf64_literal_reloc, mips_elf64_gprel32_reloc): Likewise.
