* bfd_section_* macrosAlan Modra2019-09-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

* Binutils: Always skip only 1 byte for CIE version 1's return address register.Tamar Christina2019-03-011-4/+8
| | | | | | | | | | | | | | | | | 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.

* [aarch64] Add support for pointer authentication B keySam Tebbs2018-12-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Armv8.3-A has another key used in pointer authentication called the B-key (other than the A-key that is already supported). In order for stack unwinders to work it is necessary to be able to identify frames that have been signed with the B-key rather than the A-key and it was felt that keeping this as an augmentation character in the CIE was the best bet. The DWARF extensions for ARM therefore propose to add a new augmentation character 'B' to the CIE augmentation string and the corresponding cfi directive ".cfi_b_key_frame". I've made the relevant changes to GAS and LD to add support for B-key unwinding, which required modifying LD to check for 'B' in the augmentation string, adding the ".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to GAS's fde_entry and cie_entry structs. The pointer authentication instructions will behave as NOPs on architectures that don't support them, and so a check for the architecture being assembled for is not necessary since there will be no behavioural difference between augmentation strings with and without the 'B' character on such architectures. 2018-12-05 Sam Tebbs <sam.tebbs@arm.com> bfd/ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Add check for 'B'. gas/ * dw2gencfi.c (struct cie_entry): Add tc_cie_entry_extras invocation.

* ld -r abort in _bfd_elf_write_section_eh_frameAlan Modra2014-11-111-1/+6
| | | | | | | | | | | | Turning on .eh_frame processing for ld -r resulted in systemtap tickling a ld bug. Triggered by the zero terminator not being added to .eh_frame in a separate file as it usually is (crtend.o), but instead being present in the last .eh_frame section along with CIEs and FDEs. The 4-byte terminator makes the section size check fail on 64-bit targets. * elf-eh-frame (_bfd_elf_write_section_eh_frame): Adjust section size check to account for possible zero terminator.

* Discard zero address range eh_frame FDEsAlan Modra2014-10-041-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are useless because they can't match any address. In fact, worse than useless because the .eh_frame_hdr lookup table matching addresses to FDEs does not contain information about the FDE range. The table is sorted by address; Range is inferred by the address delta from one entry to the next. So if a zero address range FDE is followed by a normal non-zero range FDE for the same address, everything is good. However, the qsort could just as easily sort the FDEs in the other order, in which case the normal FDE would effectively be seen to have a zero range. bfd/ PR 17447 * elf-bfd.h (struct eh_cie_fde): Comment re NULL u.fde.cie_inf. * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Mark zero address range FDEs for discarding.

| | | | | | | | | | | | | | With larger binaries on 64-bit systems, or indeed just binaries that have a large gap between text and data, it is possible for the .eh_frame_hdr lookup table entry values to overflow a signed 32-bit relative offset.

* Delete redundant struct cie fieldAlan Modra2014-08-221-5/+3
| | | | | | | | | | | | | | | cie->output_sec is used to when merging CIEs to ensure that only CIEs from the same output section are merged. I noticed an assignment to this field in _bfd_elf_parse_eh_frame, and thought "That's wrong, output_section isn't set properly when _bfd_elf_parse_eh_frame is called from gc-sections code". It turns out that this assignment is premature, and in fact a dead store. find_merged_cie overwrites with the correct value before the field is ever used. On looking a little more it becomes apparent that cie->cie_inf.u.cie.u.sec->output_section holds the same value, so cie->output_sec is redundant. * elf-eh-frame.c (struct cie): Delete "output_sec" field. (cie_eq, cie_compute_hash): Use output_section from cie_inf instead.
* Index PowerPC64 linker generated .eh_frame in .eh_frame_hdrAlan Modra2014-08-221-27/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed recently that .eh_frame FDEs generated by the linker for call stubs and .glink weren't being indexed in .eh_frame_hdr, due to bfd_elf_discard_info being run before the linker generated .eh_frame sections were available for parsing. This patch moves code around in elf64-ppc.c and ppc64elf.em to avoid that problem. Another problem fixed here is that --gc-sections parses .eh_frame early, and the existing machinery allows only one go at parsing the .eh_frame sections. That resulted in the linker generated .eh_frame CIEs not being merged and no .eh_frame_hdr index entries for those FDEs. It turns out that all the info from parsing .eh_frame is attached to the section, so order of parsing isn't important, and after parsing sec_info_type being set will prevent a section being parsed again. At least, when parsing doesn't hit an error. So there isn't really any need for "parsed_eh_frame". "merge_cies" is also redundant, which means _bfd_elf_{begin,end}_eh_frame_parsing can also disappear. bfd/ * elf-bfd.h (struct eh_frame_hdr_info): Delete merge_cies and parsed_eh_frames.
