2021-07-14objdump: add DWARF support for AIXClément Chigot1-0/+7

2021-07-10PR28069, assertion fail in dwarf.c:display_discr_listAlan Modra1-0/+13
We shouldn't be asserting on anything to do with leb128 values, or reporting file and line numbers when something unexpected happens. leb128 data is of indeterminate length, perfect for fuzzer mayhem. It would only make sense to assert or report dwarf.c/readelf.c source lines if the code had already sized and sanity checked the leb128 values. After removing the assertions, the testcase then gave: <37> DW_AT_discr_list : 5 byte block: 0 0 0 0 0 (label 0, label 0, label 0, label 0, <corrupt> readelf: Warning: corrupt discr_list - unrecognized discriminant byte 0x5 <3d> DW_AT_encoding : 0 (void) <3e> DW_AT_identifier_case: 0 (case_sensitive) <3f> DW_AT_virtuality : 0 (none) <40> DW_AT_decimal_sign: 5 (trailing separate) So the DW_AT_discr_list was showing more data than just the 5 byte block. That happened due to "end" pointing a long way past the end of block, and uvalue decrementing past zero on one of the leb128 bytes. PR 28069 * dwarf.c (display_discr_list): Remove assertions. Delete "end" parameter, use initial "data" pointer as the end. Formatting. Don't count down bytes as they are read. (read_and_display_attr_value): Adjust display_discr_list call. (read_and_print_leb128): Don't pass __FILE__ and __LINE__ to report_leb_status. * dwarf.h (report_leb_status): Don't report file and line numbers. Delete file and lnum parameters, (READ_ULEB, READ_SLEB): Adjust.

2021-06-15readelf: report DF_1_PIE as "Position-Independent Executable"Alan Modra1-0/+11
I finally found time to teach readelf to identify PIEs in the file header display and program header display. So in place of "DYN (Shared object file)" which isn't completely true, show "DYN (Position-Independent Executable file)". It requires a little bit of untangling code in readelf due to process_program_headers setting up dynamic_addr and dynamic_size, needed to scan .dynamic for the DT_FLAGS_1 entry, and process_program_headers itself wanting to display the file type in some cases. At first I modified process_program_header using a "probe" parameter similar to get_section_headers in order to inhibit output, but decided it was cleaner to separate out locate_dynamic_sections. binutils/ * readelf.c (locate_dynamic_section, is_pie): New functions. (get_file_type): Replace e_type parameter with filedata. Call is_pie for ET_DYN. Update all callers.

2021-06-14Use consistent type in binutils/dwarf.cEric Botcazou1-0/+7
If you look at the type used for implicit_const objects in binutils/dwarf.c, you'll get sometimes bfd_signed_vma and sometimes dwarf_signed_vma. They are the same on 64-bit hosts, but not on 32-bit hosts, and the latter discrepancy, in particular in process_abbrev_set, is responsible for the following error issued by objdump on some object files containing DWARF 5: binutils/dwarf.c:1108: read LEB value is too large to store in destination variable binutis/ * dwarf.c (struct abbrev_attr): Change type of implicit_const. (add_abbrev_attr): Likewise. (process_abbrev_set): Likewise. (display_debug_abbrev): Adjust to above change.
2021-06-12readelf: don't clear section_headers in process_file_headerAlan Modra1-0/+4
* readelf.c (process_file_header): Don't clear section_headers.
2021-06-12Re: readelf section readingAlan Modra1-0/+7
Fix commit 4de91c10cdd9, which cached the single section header read to pick up file header extension fields. Also, testing e_shoff in get_section_headers opened a hole for fuzzers where we'd end up with segfaults due to non-zero e_shnum but NULL section_headers. * readelf.c (get_section_headers): Don't test e_shoff here, leave that to get_32bit_section_headers or get_64bit_section_headers. (process_object): Throw away section header read to print file header extension.
2021-06-11readelf info leaks from one object to the nextAlan Modra1-0/+6
A number of filedata entries were not cleared. Make sure they are all cleared out, except the ones needed for archive handling. * readelf.c (struct filedata): Move archive_file_offset and archive_file_size earlier. (free_filedata): Clear using memset.
2021-06-11readelf section readingAlan Modra1-0/+14
This is a followup to git commit 8ff66993e0b5, a patch aimed at segfaults found invoking readelf multiple times with fuzzed objects. In that patch I added code to clear more stashed data early in process_section_headers, along with any stashed section headers. This patch instead relies on clearing out the stash at the end of process_object, making sure that process_object doesn't exit early. The patch also introduces some new wrapper functions. * readelf.c (GET_ELF_SYMBOLS): Delete. Replace with.. (get_elf_symbols): ..this new function throughout. (get_32bit_section_headers): Don't free section_headers. (get_64bit_section_headers): Likewise. (get_section_headers): New function, use throughout in place of 32bit and 64bit variants. (get_dynamic_section): Similarly. (process_section_headers): Don't free filedata memory here. (get_file_header): Don't get section headers here.. (process_object): ..Read them here instead. Don't exit without freeing filedata memory.

Splitting up help strings makes it more likely that at least some of the help translation survives adding new options. * readelf.c (parse_args): Call dwarf_select_sections_all on --debug-dump without optarg.

2021-05-29MIPS/opcodes: Do not use CP0 register names for control registersMaciej W. Rozycki1-0/+6
The CP0 control register set has never been defined, however encodings for the CFC0 and CTC0 instructions remained available for implementers up until the MIPS32 ISA declared them invalid and causing the Reserved Instruction exception[1]. Therefore we handle them for both assembly and disassembly, however in the latter case the names of CP0 registers from the regular set are incorrectly printed if named registers are requested. This is because we do not define separate operand classes for coprocessor regular and control registers respectively, which means the disassembler has no way to tell the two cases apart. Consequently nonsensical disassembly is produced like: cfc0 v0,c0_random Later the MIPSr5 ISA reused the encodings for XPA ASE MFHC0 and MTHC0 instructions[2] although it failed to document them in the relevant opcode table until MIPSr6 only. Correct the issue then by defining a new register class, OP_REG_CONTROL, and corresponding operand codes, `g' and `y' for the two positions in the machine instruction a control register operand can take. Adjust the test cases affected accordingly. While at it swap the regular MIPS opcode table "cfc0" and "ctc0" entries with each other so that they come in the alphabetical order.

2021-05-28x86: Restore PC16 relocation overflow checkH.J. Lu1-0/+5
The x86-64 psABI has --- A program or object file using R_X86_64_8, R_X86_64_16, R_X86_64_PC16 or R_X86_64_PC8 relocations is not conformant to this ABI, these relocations are only added for documentation purposes. --- Since x86 PC16 relocations have been used for 16-bit programs in an ELF32 or ELF64 container, PC16 relocation should wrap-around in 16-bit address space.
