2023-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
2022-11-23asan: NULL deref in filter_symbolsAlan Modra1-0/+1
If tdata->symbols is NULL, make tdata->symcount zero too. This makes wasm_get_symtab_upper_bound return the proper result and stops cascading errors. * wasm-module.c (wasm_scan_name_function_section): Clear tdata->symcount on error.
2022-09-06bfd: Add bfd_find_nearest_line_with_altAaron Merey1-0/+1
bfd_find_nearest_line_with_alt functions like bfd_find_nearest_line with the addition of a parameter for specifying the filename of a supplementary debug file such as one referenced by .gnu_debugaltlink or .debug_sup. This patch focuses on implementing bfd_find_nearest_line_with_alt support for ELF/DWARF2 .gnu_debugaltlink. For other targets this function simply sets the invalid_operation bfd_error.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
2021-12-17asan: abort in wasm_scan_name_function_sectionAlan Modra1-1/+2
Macros like READ_LEB128 in wasm-module.c that alter control flow are evil. Maintainers will break your code if you have hidden ways to reach labels. * wasm-module.c (wasm_scan_name_function_section): Don't attempt to bfd_release NULL.
2021-05-22bfd dwarf2 sanity checkingAlan Modra1-5/+2
This patch is aimed at the many places in dwarf2.c that blindly increment a data pointer after calling functions that are meant to read a fixed number of bytes. The problem with that is with damaged dwarf we might increment a data pointer past the end of data, which is UB and complicates (ie. bugs likely) any further use of that data pointer. To fix those problems, I've moved incrementing of the data pointer into the functions that do the reads. _bfd_safe_read_leb128 gets the same treatment for consistency. * libbfd.c (_bfd_safe_read_leb128): Remove length_return parameter. Replace data pointer with pointer to pointer. Increment pointer over bytes read. * libbfd-in.h (_bfd_safe_read_leb128): Update prototype. * elf-attrs.c (_bfd_elf_parse_attributes): Adjust to suit. Be careful not to increment data pointer past end. Remove now redundant pr17512 check. * wasm-module.c (READ_LEB128): Adjust to suit changes to _bfd_safe_read_leb128. * dwarf2.c (read_n_bytes): New inline function, old one renamed to.. (read_blk): ..this. Allocate and return block. Increment bfd_byte** arg. (read_3_bytes): New function. (read_1_byte, read_1_signed_byte, read_2_bytes, read_4_bytes), (read_8_bytes, read_string, read_indirect_string), (read_indirect_line_string, read_alt_indirect_string): Take a byte_byte** arg which is incremented over bytes read. Remove any bytes_read return. Rewrite limit checks to compare lengths rather than pointers. (read_abbrevs, read_attribute_value, read_formatted_entries), (decode_line_info, find_abstract_instance, read_ranges), (read_rnglists, scan_unit_for_symbols, parse_comp_unit), (stash_comp_unit): Adjust to suit. Rewrite limit checks to compare lengths rather than pointers. * libbfd.h: Regenerate.
2021-04-05C99 bfd configuryAlan Modra1-3/+0
Certain library headers and functions are required by C99. This removes configure tests for them. The patch also removes AC_ISC_POSIX and AC_HEADER_DIRENT, which the autoconf manual states are obsolescent. sys/time.h is no longer tangled up with time.h so it can be handled by the gprof configure. * configure.ac: Don't check for long long or long double type. Don't check for alloca.h, limits.h, stddef.h, stdlib.h, string.h, strings.h, time.h, wchar.h, wctype.h or sys/time.h. Don't check for strtoull, free, malloc, realloc, getenv, strstr, snprintf, vsnprintf, strlen or setitimer. Sort AC_CHECK_DECLS. (AC_ISC_POSIX): Don't invoke. (AC_HEADER_TIME, AC_HEADER_DIRENT, ACX_HEADER_STRING): Likewise. * sysdep.h: Remove many HAVE_*_H checks and fallback declarations. Do test HAVE_SYS_TYPES_H. Don't include sys/time.h. Reorder header order as per automake AC_INCLUDES_DEFAULT. * bfd-in.h: Include inttypes.h unconditionally. * bfd.c (_bfd_doprnt, _bfd_doprnt_scan): Assume long long and long double are available. (bfd_scan_vma): Assume long long and strtoull are available. * elflink.c: Include limits.h unconditionally. * elfnn-riscv.c: Likewise. * wasm-module.c: Likewise. * hpux-core.c: Include dirent.h unconditionally. * trad-core.c: Likewise. * hosts/x86-64linux.h: Include stdlib.h unconditionally. * peXXigen.c: Remove HAVE_WCHAR_H and HAVE_WCTYPE_H checks. * elf32-m68hc1x.c: Don't include alloca-conf.h. * elf64-hppa.c: Likewise. * som.c: Likewise. * wasm-module.c: Likewise. * xsym.c: Likewise. * bfd-in2.h: Regenerate. * config.in: Regenerate. * configure: Regenerate.

2021-02-17read_leb128 overflow checkingAlan Modra1-7/+20
There is a tiny error left in dwarf.c:read_leb128 after Nick fixed the signed overflow problem in code I wrote. It's to do with sleb128 values that have unnecessary excess bytes. For example, -1 is represented as 0x7f, the most efficient encoding, but also as 0xff,0x7f or 0xff,0xff,0x7f and so on. None of these sequences overflow any size signed value, but read_leb128 will report an overflow given enough excess bytes. This patch fixes that problem, and since the proper test for signed values with excess bytes can easily be adapted to also test a sleb byte with just some bits that overflow the result, I changed the code to not use signed right shifts. (The C standard ISO/IEC 9899:1999 6.5.7 says signed right shifts of negative values have an implementation defined value. A long time ago I even used a C compiler for a certain microprocessor that always did unsigned right shifts. Mind you, it is very unlikely to be compiling binutils with such a compiler.) bfd/ * wasm-module.c: Guard include of limits.h. (CHAR_BIT): Provide backup define.

2021-01-07ELF: Don't generate unused section symbolsH.J. Lu1-0/+1
For ELF targets, section symbols are required only for relocations. With -ffunction-sections -fdata-sections, there can be many unused section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are With unused section symbols : 39411698 bytes Without unused section symbols: 39227002 bytes The unused section symbols in libstdc++.a occupy more than 180 KB. Add BSF_SECTION_SYM_USED to indicate if a section symbol should be included in the symbol table. The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed. Tested on Linux/x86. Other ELF backends need to: 1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE. 2. Mark used section symbols in assembler backend. 3.

2020-03-02bfd_cleanup for object_pAlan Modra1-2/+2
The object_p (and archive_p, core_file_p) functions are not supposed to have any target specific malloc'd memory attached to the bfd on their return. This should be obvious on a failure return, but it's also true for a successful return. The reason is that even though the object_p recognises the file, that particular target may not be used and thus the bfd won't be closed calling close_and_cleanup for the target that allocated the memory. It turns out that the object_p bfd_target* return value isn't needed. In all cases except ld/plugin.c the target is abfd->xvec and with ld/plugin.c the target isn't used. So this patch returns a cleanup function from object_p instead, called in bfd_check_format_matches to tidy the bfd before trying a different target match. The only cleanup that does anything at this stage is the alpha-vms one. bfd/ * targets.c (bfd_cleanup): New typedef.

2020-02-19bfd_size_type to size_tAlan Modra1-1/+1
bfd_size_type was invented a long time ago in the K&R days. Many places in binutils ought to be using size_t instead (and there are lots of places that use long or unsigned long that really ought to use size_t too). Note that you can't change everything over to size_t: A 32-bit host needs a larger type than size_t to support reading and processing of 64-bit ELF object files. This patch just tidies some of the more obvious uses of bfd_size_type that could be size_t. There no doubt are more lurking in the source. Incidentally, practically all functions used for output of object files can use size_t and don't need to worry about overflow of size expressions. If you have something like symcount * sizeof (void *) when symcount is counting symbols already in memory then you know that this expression can't overflow since the size of a symbol in memory is larger by far than that of a pointer. * aix386-core.c (aix386_core_file_p): Use size_t for "amt". * aout-target.h (object_p): Likewise. * aout-tic30.c (tic30_aout_object_p): Likewise. * aoutx.h

2020-01-13Memory leaks and ineffective bounds checking in wasm_scanAlan Modra1-56/+44
It's always a bad idea to perform arithmetic on an unknown value read from an object file before comparing against bounds. Code like the following attempting to bounds check "len", a 64-bit value, isn't effective because the pointer arithmetic ignores the high 32 bits when compiled for a 32-bit host. READ_LEB128 (len, p, end); if (p + len < p || p + len > end) goto error_return; Instead, perform any arithmetic on known values where we don't need to worry about overflows: READ_LEB128 (len, p, end); if (len > (size_t) (end - p)) goto error_return; I'll note that this check does do things the right way: READ_LEB128 (symcount, p, end); /* Sanity check: each symbol has at least two bytes. */ if (symcount > payload_size / 2) return FALSE; "symcount * 2 > payload_size" would be wrong since the multiply could overflow. * wasm-module.c (wasm_scan_name_function_section): Formatting. Delete asect name check. Move asect NULL check to wasm_object_p. Correct bounds check of sizes against end. Replace uses of bfd_zalloc with bfd_alloc, zeroing only necessary bytes. Use just one bfd_release. (wasm_scan): Don't use malloc/strdup for section names, bfd_alloc instead. Simplify code prefixing section name. Formatting. Don't attempt to free memory here.. (wasm_object_p): ..do so here. Formatting.

2018-02-16Remove bfd stub function casts.Alan Modra1-5/+5
This patch defines a bunch of new functions to use in the BFD target structs rather than casting bfd_false or bfd_true and similar stub functions. I've also renamed the stub functions to reflect their parameters and put "error" in the name if they set bfd_error. The latter change is important since there were quite a few uses of bfd_false where setting bfd_error was inappropriate, for example in elf_backend_allow_non_load_phdr and is_target_special_symbol. * libbfd.c (_bfd_bool_bfd_false_error): Rename from bfd_false.

2018-02-14Fix compilation of the BFD sub-directory with a gcc v8 compiler by adding ↵Nick Clifton1-1/+1
extra casts. GCC v8 issues warnings about mis-matching casts of function pointers. A previous patch tried to fix this problem by adding new dummy functions which accepted a variable number of arguments. But this introduces serious problems when compiled with other versions of gcc, (notably gcc 4.4). This patch reverts that previous solution and instead adds extra casts (to function types without a parameter list). For more details see: https://sourceware.org/ml/binutils/2018-02/msg00198.html PR 22823 Revert previous delta.
