PR24511, nm should not mark symbols in .init_array as "t" This patch restricts the section names matched in coff_section_type, a function that translates section names to symbol type, and arranges to translate section flags to symbol type before looking at names. The latter change resulted in various test failures due to improper section flags being used in tests, and by the plugin support, so fix that too. The new test fails on many ELF targets that lack .init/fini_array in their scripts. I've just xfailed those. pru-elf oddly defines __init_array_begin rather than __init_array_start. I've left that target as a FAIL, and pj-elf too which reports an error for undefined weak symbols. bfd/ PR 24511 * syms.c (coff_section_type): Only allow '.', '$' and numeric following the standard section names.

[BFD, AArch64] Improve bti/pac plts. This patch aims to improve the definitions of BTI and PAC based PLTs.

Thus both PAC plt0 and BTI+PAC plt0 are removed and we can use basic plt0 and BTI plt0 instead, respectively. * We can remove the extra padding nops when we add the new bti instructions. BTI plt0 and BTI TLSDESC plt are updated. * For better performance PLTn could be padded to 24bytes.

[binutils, ARM, 16/16] Add support to VLDR and VSTR of system registers GNU as' Arm backend assumes each mnemonic has a single entry in the instruction table but VLDR (system register) and VSTR (system register) are different instructions than VLDR and VSTR. It is thus necessary to add some form of demultiplexing in the parser. It starts by creating a new operand type OP_VLDR which indicate that the operand is either the existing OP_RVSD operand or a system register. The function parse_operands () then tries these two cases in order, calling the new parse_sys_vldr_vstr for the second case. Since the encoding function is specified in the instruction table entry, it also need to have some sort of demultiplexing. This is done in do_vldr_vstr which either calls the existing do_neon_ldr_str () or calls the new do_t_vldr_vstr_sysreg (). A new internal relocation is needed as well since the offset has a shorter range than in other Thumb coprocessor instructions. Disassembly also requires special care since VSTR (system register) reuse the STC encoding with the coprocessor number 15. Armv8.1-M Mainline ARM manual states that coprocessor 8, 14 and 15 are reserved for floating-point and MVE instructions a feature bit check is added if the coprocessor number is one of this value and we are trying to match a coprocessor instruction (eg. STC) to forbid the match.

AArch64: When DF_BIND_NOW don't use TLSDESC GOT value. When using DF_BIND_NOW on AArch64 we don't reserve the GOT slot for a TLSDESC, but we still emitted DT_TLSDESC_GOT and DT_TLSDESC_PLT. This caused random memory corruption as the "special" value of (bfd_vma)-1 would be set for dt_tlsdesc_got. Since we don't have a value of dt_tlsdesc_got I also don't emit DT_TLSDESC_PLT now becuase it would point to an incomplete PLT. To be able to write the PLT entry DT_TLSDESC_GOT is needed and since we don't have one we can't write the PLT entry either. It is my understanding that GLIBC doesn't need these two entries when not lazy loading. Conversely AArch32 does not reserve neither the GOT not the PLT slot when doing DF_BIND_NOW. AArch32 does not need these checks because these values are initialized to 0 and so the if (...) checks don't pass, but on AArch64 these are initialized to (bfd_vma)-1 and thus we need some extra checks. bfd/ChangeLog: PR ld/24302 * elfnn-aarch64.c (elfNN_aarch64_size_dynamic_sections): Don't emit DT_TLSDESC_GOT and DT_TLSDESC_PLT when DF_BIND_NOW.

PR24355, segmentation fault in function called from ppc_finish_symbols 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.

[BFD, LD, AArch64, 3/3] Add --pac-plt to enable PLTs protected with PAC. 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.

[BFD, LD, AArch64, 2/3] Add --force-bti to enable BTI and to select BTI 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.

Don't use bfd_get_file_size in objdump 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.

PR24311, FAIL: S-records with constructors 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.

Binutils: Always skip only 1 byte for CIE version 1's return address register. 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.
