2019-04-02RISC-V: Don't check ABI flags if no code section.Jim Wilson2-2/+39
This fixes a glib build failure reported in PR 24389. Using ld -b binary creates an object file with no elf header flags set which has the wrong ABI info for riscv64-linux. But the file also has no code sections, so I added code borrowed from the arm port that only checks the ELF header ABI flags if there is a code section. bfd/ PR 24389 * elfnn-riscv.c (_bfd_riscv_elf_merge_private_bfd_data): Move read of ELF header flags to after check for ELF object file. Loop through sections looking for code sections, if none, then skip ABI checks.

2019-03-21RISC-V: Fix linker crash in section symbol check.Jim Wilson2-1/+9
sym is only set for local symbols. h is only set for global symbols. Gas won't let me create a global section symbol, but bfd appears to have some support for that, and I can't rule out that other assemblers might do this.

2019-03-21[BFD, AArch64, x86] Improve warning for --force-btiSudakshina Das7-14/+45
The AArch64 linker option to turn on BTI (--force-bti) warns in case there are input objects which have a missing GNU NOTE section for BTI. This patch is trying to improve the warnings that come out. In order to do so, I propose adding a new argument to elf_merge_gnu_properties and the backend function merge_gnu_properties. This new argument makes sure that we now pass both the objects along with the properties to which they belong to. The x86 backend function has also been updated to match this change. *** bfd/ChangeLog *** 2019-03-21 Sudakshina Das <sudi.das@arm.com> * elf-bfd.h (struct elf_backend_data): Add argument to merge_gnu_properties. * elf-properties.c (elf_merge_gnu_properties): Add argument to itself and while calling bed->merge_gnu_properties.

2019-03-18PR24355, segmentation fault in function called from ppc_finish_symbolsAlan Modra2-6/+9
This one looks to be a bug going back to 2009, git commit e054468f6c "STT_GNU_IFUNC support for PowerPC". That bug was carried over with git commit 49c09209d0 "Rearrange PLT reloc output on powerpc". If the refcount for an ifunc local sym plt entry was zero, ppc_elf_size_dynamic_sections would correctly set plt.offset to -1 but leave glink_offset uninitialized. That leads to occasional segfaults (which can be made solid with MALLOC_PERTURB_=1 when using glibc). So, guard the write_glink_stub call with plt.offset != -1. Also, remove the totally ineffective attempt at writing multiple-use glink stubs only once. PR 24355 * elf32-ppc.c (ppc_finish_symbols): Don't call write_glink_stub for local iplt syms with ent->plt.offset == -1. Remove ineffective attempt at writing glink stubs only once.

2019-03-13[BFD, LD, AArch64, 3/3] Add --pac-plt to enable PLTs protected with PAC.Sudakshina Das2-6/+145
This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds new definitions of PAC enabled PLTs and both BTI and PAC enabled PLTs. 2) It also defines the new dynamic tag DT_AARCH64_PAC_PLT for the PAC enabled PLTs. 3) This patch adds a new ld command line option: --pac-plt. In the presence of this option, the linker uses the PAC enabled PLTs and marks with DT_AARCH64_PAC_PLT. 4) In case both BTI and PAC are enabled the linker should pick PLTs enabled with both and also use dynamic tags for both.

enabled PLTs This is part of the patch series to add support for BTI and PAC in AArch64 linker. 1) This patch adds a new ld command line option: --force-bti. In the presence of this option, the linker enables BTI with the GNU_PROPERTY_AARCH64_FEATURE_1_BTI feature. This gives out warning in case of missing gnu notes for BTI in inputs. 2) It also defines a new set of BTI enabled PLTs. These are used either when all the inputs are marked with GNU_PROPERTY_AARCH64_FEATURE_1_BTI or when the new --force-bti option is used. This required adding new fields in elf_aarch64_link_hash_table so that we could make the PLT related information more generic. 3) It also defines a dynamic tag DT_AARCH64_BTI_PLT.

2019-03-12Don't use bfd_get_file_size in objdumpAlan Modra8-79/+164
Compressed debug sections can have uncompressed sizes that exceed the original file size, so we can't use bfd_get_file_size. objdump also used bfd_get_file_size to limit reloc section size, but I believe the underlying bug causing the PR22508 out of bounds buffer access was that we had an integer overflow when calculating the reloc buffer size. I've fixed that instead in most of the backends, som and vms-alpha being the exceptions. SOM and vmd-alpha have rather more serious bugs in their slurp_relocs routines that would need fixing first if we want to fuss about making them safe against fuzzed object files.
