2024-05-29readelf: Use section names for displaying RELR relocsSzabolcs Nagy1-8/+24
In some cases using section names instead of symbol names for displaying an address is more useful. If the symbol falls outside the section where the address is then likely it is not useful to display the address relative to. And if symbols are stripped from a binary then printing the section that contains the address is more useful than printing <no sym>.
2024-05-29readelf: Fix symbol display for RELR relocsSzabolcs Nagy1-17/+125
Filter symbols before binary searching for the right symbol to display for a given address, such that only displayable symbols are present and at most one per address. The current logic does not handle multiple symbols for the same address well if some of them are empty, the selected symbol is not stable with respect to an unrelated symbol table change and on aarch64 often mapping symbols are displayed which is not useful. Filtering solves these problems at the cost of a linear scan of the sorted symbol table. The heuristic to select the best symbol likely could be improved, this patch aims to improve symbol display for RELR without complex logic such that the output is useful and stable for ld tests.

2024-03-25bfd: make _bfd_section_size_insane part of the public APIAndrew Burgess1-1/+1
If a BFD user is making use of a function like bfd_get_section_contents to read a section into a pre-allocated buffer, then that BFD user might also want to make use of _bfd_section_size_insane prior to allocating the buffer they intend to use in order to validate that the buffer size that plan to allocate is sane. This commit makes _bfd_section_size_insane public, by renaming it to bfd_section_size_insane. I've updated the existing uses within bfd/, I don't believe this function is used outside of bfd/ currently. One place that I plan to make use of this function is in gdb/gdb_bfd.c, in the function gdb_bfd_get_full_section_contents. This change isn't included in this commit, but will come later if/when this has been merged into bfd. There should be no change in behaviour after this commit. bfd/ * bfd-in2.h (bfd_section_size_insane): Add declaration. * compress.c (bfd_get_full_section_contents): Update for new name of _bfd_section_size_insane.

2023-09-29x86-64: Add -z mark-plt and -z nomark-pltH.J. Lu1-0/+19
The PLT entry in executables and shared libraries contains an indirect branch, like jmp *foo@GOTPCREL(%rip) push $index_foo jmp .PLT0 or endbr64 jmp *foo@GOTPCREL(%rip) NOP padding which is used to branch to the function, foo, defined in another object. Each R_X86_64_JUMP_SLOT relocation has a corresponding PLT entry. The dynamic tags have been added to the x86-64 psABI to mark such PLT entries: https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/6d824a52a42d173eb838b879616c1be5870b593e Add an x86-64 linker option, -z mark-plt, to mark PLT entries with #define DT_X86_64_PLT (DT_LOPROC + 0) #define DT_X86_64_PLTSZ (DT_LOPROC + 1) #define DT_X86_64_PLTENT (DT_LOPROC + 3) 1.

2023-08-03readelf sprintf optimisationAlan Modra1-721/+1050
This replaces sprintf and strcat calls with stpcpy, and makes use of sprintf return value rather than using strlen, for get_machine_flags. decode_NDS32_machine_flags made use of snprintf, which is arguably the "correct" way to do things if there can be a buffer overflow. In this case I don't think there can be, the buffer is 1k in size which is at least 5 times more than needed. What's more, snprintf returns the count of chars that would be output given no buffer limit, which means code like r += snprintf (buf + r, size - r, ...); r += snprintf (buf + r, size - r, ...); is just wrong. There needs to be a check on the return value in order to prevent buf + r being out of bounds for the second snprintf call. BTW, if you look closely you'll see the return value of the decode functions is unused. I admit to getting a little carried away with writing "out = stpcpy (out, ...):" in each of the decode functions and didn't notice that until get_machine_flags was trimmed down to a much smaller size. When I did notice, I decided it's not such a bad thing. * readelf.c (decode_ARC_machine_flags, decode_ARM_machine_flags), (decode_AVR_machine_flags, decode_NDS32_machine_flags), (decode_AMDGPU_machine_flags): Use stpcpy and sprintf return value.

2023-07-30bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flagsJose E. Marchesi1-0/+6
This patch adds support for EF_BPF_CPUVER bits in the ELF machine-dependent header flags. These bits encode the BPF CPU version for which the object file has been compiled for. The BPF assembler is updated so it annotates the object files it generates with these bits. The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the appropriate ISA version if the user didn't specify an explicit ISA version in the command line. Note that a value of zero in EF_BPF_CPUVER is interpreted by the disassembler as "use the later supported version" (the BPF CPU versions start with v1.) The readelf utility is updated to pretty print EF_BPF_CPUVER when it prints out the ELF header: $ readelf -h a.out ELF Header: ...

2023-07-07arc: Update/Add ARCv3 support.Claudiu Zissulescu1-2/+28
The ARC HS5x and ARC HS6x processors are based on the new ARCv3 ISA that implements a full range of 32-bit and 64-bit instructions. These processors feature a high-speed 10-stage, dual-issue pipeline that offers increased utilization of functional units with a limited increase in power and area. The HS5x processors feature a 32-bit pipeline that can execute all ARCv3 32-bit instructions, while the HS6x processors feature a full 64-bit pipeline and register file that can execute both 32-bit and 64-bit instructions. In addition, the ARC HS6x supports 64-bit virtual and 52-bit physical address spaces to enable direct addressing of current and future large memories, as well as 128-bit loads and stores for efficient data movement.

I likely won't do that, but the compression header ch_type field isn't just ELF specific if these headers are to be used in COFF/PE too. bfd/ * bfd.c (bfd_update_compression_header), (bfd_check_compression_header, bfd_get_compression_header_size), (bfd_convert_section_size, bfd_convert_section_contents): Move to.. * compress.c: ..here. (enum compression_type): New. Use it throughout file. * elf.c (_bfd_elf_make_section_from_shdr): Replace uses of ELFCOMPRESS_ZLIB and ELFCOMPRESS_ZSTD with ch_compress_zlib and ch_compress_zstd. * bfd-in2.h: Regenerate. binutils/ * readelf.c (process_section_headers, dump_section_as_strings), (dump_section_as_bytes, load_specific_debug_section): Replace uses of ELFCOMPRESS_ZLIB and ELFCOMPRESS_ZSTD with ch_compress_zlib and ch_compress_zstd.

2022-11-23Don't use "long" in readelf for file offsetsAlan Modra1-472/+505
The aim here is to improve readelf handling of large 64-bit object files on LLP64 hosts (Windows) where long is only 32 bits. The patch changes more than just file offsets. Addresses and sizes are also changed to avoid "long". Most places get to use uint64_t even where size_t may be more appropriate, because that allows some overflow checks to be implemented easily (*alloc changes). * dwarf.c (cmalloc, xcmalloc, xcrealloc, xcalloc2): Make nmemb parameter uint64_t. * dwarf.h: Update prototypes. (struct dwarf_section): Make num_relocs uint64_t. * elfcomm.c (setup_archive): Update error format. * elfcomm.h (struct archive_info): Make sym_size, longnames_size, nested_member_origin, next_arhdr_offset uint64_t. * readelf.c (struct filedata): Make archive_file_offset, archive_file_size, string_table_length, dynamic_addr, dynamic_nent, dynamic_strings_length, num_dynamic_syms, dynamic_syminfo_offset uint64_t. (many functions): Replace uses of "unsigned long" with "uint64_t" or "size_t".
2022-11-23Re: readelf: use fseeko64 or fseeko if possibleAlan Modra1-51/+74
Replace the macros with a small wrapper function that verifies the fseek offset arg isn't overlarge. * readelf.c (FSEEK_FUNC): Delete, replace uses with.. (fseek64): ..this new function. (process_program_headers): Don't cast p_offset to long.
