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. The linker uses this whenever it picks BTI enabled PLTs.

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.

2019-03-08PR24311, FAIL: S-records with constructorsAlan Modra2-22/+39
Not padding string merge section output to its alignment can cause failures of the S-record tests when input string merge sections are padded, since the ELF linker output for the single string section would shrink compared to the SREC linker output. That might result in following sections having different addresses. On the other hand, padding string merge section output when input string merge sections are *not* padded can also cause failures, in this case due to the ELF linker output for the string section being larger (due to padding) than the SREC linker output. It would be better to write a more robust test, but it is also nice to leave input unchanged when no string merges occur. PR 24311 * merge.c (merge_strings): Return secinfo.

2019-03-01Binutils: Always skip only 1 byte for CIE version 1's return address register.Tamar Christina2-4/+12
According to the specification for the CIE entries, when the CIE version is 1 then the return address register field is always 1 byte. Readelf does this correctly in read_cie in dwarf.c but ld does this incorrectly and always tries to read a skip_leb128. If the value here has the top bit set then ld will incorrectly read at least another byte, causing either an assert failure or an incorrect address to be used in eh_frame. I'm not sure how to generate a generic test for this as I'd need to write assembly, and it's a bit hard to trigger. Essentially the relocated value needs to start with something that & 0x70 != 0x10 while trying to write a personality. bfd/ChangeLog: * elf-eh-frame.c (_bfd_elf_write_section_eh_frame): Correct CIE parse.
