2017-12-19	PR22626, invalid dynindx used for dynamic relocs against section syms	Alan Modra	2	-8/+22
	_bfd_elf_link_renumber_dynsyms is called twice by the linker. The first call in bfd_elf_size_dynamic_sections is just to answer the question as to whether there are there any dynamic symbols. The second call in bfd_elf_size_dynsym_hash_dynstr sets the st_shndx value that dynamic symbols will have. strip_excluded_output_sections is called between these two calls. So sections seen on the first _bfd_elf_link_renumber_dynsyms pass might differ from those seen on the second pass. Unfortunately, that can result in a stripped section's dynamic symbol being assigned a dynindx on the first pass but not corrected to the final value (of zero, ie. not dynamic) on the second pass. PowerPC, x86, mips, and most other targets that emit dynamic section symbols, just test that section symbol dynindx is non-zero before using a given section symbol in dynamic relocations. This patch prevents _bfd_elf_link_renumber_dynsyms from setting any section symbol dynindx on the first pass. PR 22626 * elflink.c (_bfd_elf_link_renumber_dynsyms): Don't set section dynindx when section_sym_count is NULL. (bfd_elf_size_dynamic_sections): Pass NULL section_sym_count to preliminary _bfd_elf_link_renumber_dynsyms call.

2017-12-13	[BFD][AARCH64]Disallow R_AARCH64_ABS32(LP64) & R_AARCH64_ABS16 in const ↵	Renlin Li	2	-0/+27
	section of shared object. R_AARCH64_ABS64, R_AARCH64_ABS32 and R_AARCH64_ABS16 are data relocations supported in AArch64 elf ABI. R_AARCH64_ABS64 under LP64 is allowed in shared object and a dynamic relocation entry will be generated. This allows the dynamic linker to do further symbol resolution. R_AARCH64_ABS32 likewise is allowed in shared object, however under ILP32 abi. The original behavior for R_AARCH64_ABS32 under LP64 is that, it's allowed in shared object and silently resolved at static linking time. No dynamic relocation entry is generate for it. R_AARCH64_ABS16 is allowed in shared object under both L64 and ILP32. It's resolved at static linking time as well. Under LP64, the address should be 64-bit. R_AARCH64_ABS32 relocation indicates an address that is only sized 32 bits which is meaningless in LP64 shared object. It's useful to error out. I have checked glibc dynamic linker code, R_AARCH64_ABS16 is not supported at all. So R_AARCH64_ABS16 should be reject in shared object completely. In this patch, R_AARCH64_ABS32 is rejected under LP64 in constant section of shared object. R_AARCH64_ABS16 is rejected in constant section of shared object in both ABI. This will sometimes provide useful information for buggy code.

2017-12-08	Fix stripping relocs in a file with mergeable notes.	Nick Clifton	2	-0/+10
	A recent Fedora bug (1520805) exposed a problem with objcopy's reloc copying code, when a binary also contains mergeable notes. The note merging code would delete some relocs, but then the reloc copying code would try to put them back again, which did not work. So I am checking in the patch below to fix the problem. The patch also tweaks one of the binutils note merging tests so that it is skipped for the Sparc64 target, since this has funky relocs. binutils * objcopy.c (copy_relocations_in_section): Use the orelocations field of the input section, if it has been initialised. * testsuite/binutils-all/note-2-64.d: Skip test on Sparc64. bfd * elfcode.h (elf_write_relocs): Check for an empty howto field.
