2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
2023-08-09Rename bfd_bread and bfd_bwriteAlan Modra1-71/+71
These were renamed from bfd_read and bfd_write back in 2001 when they lost an unnecessary parameter. Rename them back, and get rid of a few casts that are only needed without prototyped functions (K&R C).
2023-06-21macho-o.c don't leak strtabAlan Modra1-0/+2
* mach-o.c (bfd_mach_o_write_symtab_content): Free strtab on success path.
2023-06-07_bfd_free_cached_infoAlan Modra1-10/+17
doc/bfdint.texi and comments in the aout and som code about this function are just wrong, and its name is not very apt. Better would be _bfd_mostly_destroy, and we certainly should not be saying anything about the possibility of later recreating anything lost by this function. What's more, if _bfd_free_cached_info is called when creating an archive map to reduce memory usage by throwing away symbols, the target _close_and_cleanup function won't have access to tdata or section bfd_user_data to tidy memory. This means most of the target _close_and_cleanup function won't do anything, and therefore sometimes will result in memory leaks. This patch fixes the documentation problems and moves most of the target _close_and_cleanup code to target _bfd_free_cached_info. Another notable change is that bfd_generic_bfd_free_cached_info is now defined as _bfd_free_cached_info rather than _bfd_bool_bfd_true, ie. the default now frees objalloc memory.
2023-03-17mach-o: out of memory in get_dynamic_reloc_upper_boundAlan Modra1-26/+29
* mach-o.c (bfd_mach_o_canonicalize_dynamic_reloc): Move sanity checks.. (bfd_mach_o_get_dynamic_reloc_upper_bound): ..to here.
2023-03-06macho null dereference readAlan Modra1-3/+3
The main problem here was not returning -1 from canonicalize_symtab on an error, leaving the vector of relocs only partly initialised and one with a null sym_ptr_ptr. * mach-o.c (bfd_mach_o_canonicalize_symtab): Return -1 on error, not 0. (bfd_mach_o_pre_canonicalize_one_reloc): Init sym_ptr_ptr to undefined section sym.
2023-02-10objcopy of mach-o indirect symbolsAlan Modra1-0/+9
Anti-fuzzer measure. I'm not sure what the correct fix is for objcopy. Probably the BFD_MACH_O_S_NON_LAZY_SYMBOL_POINTERS, BFD_MACH_O_S_LAZY_SYMBOL_POINTERS and BFD_MACH_O_S_SYMBOL_STUBS contents should be read. * mach-o.c (bfd_mach_o_section_get_nbr_indirect): Omit sections with NULL sec->indirect_syms.
2023-01-01Update 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.

2022-11-10Sanity check reloc count in get_reloc_upper_boundAlan Modra1-6/+16
The idea here is the stop tools from allocating up to 32G per section for the arelent pointer array, only to find a little later that the section reloc count was fuzzed. This usually doesn't hurt much (on systems that allow malloc overcommit) except when compiled with asan. We already do this for ELF targets, and while fixing the logic recently I decided other targets ought to do the same. * elf64-sparc.c (elf64_sparc_get_reloc_upper_bound): Sanity check section reloc count against file size. * mach-o.c (bfd_mach_o_get_reloc_upper_bound): Likewise. * aoutx.h (get_reloc_upper_bound): Likewise, and don't duplicate check done in bfd_get_reloc_upper_bound. * pdp11.c (get_reloc_upper_bound): Likewise. * coffgen.c (coff_get_reloc_upper_bound): Likewise.
2022-10-14PR29677, Field `the_bfd` of `asymbol` is uninitialisedAlan Modra1-41/+31
Besides not initialising the_bfd of synthetic symbols, counting symbols when sizing didn't match symbols created if there were any dynsyms named "". We don't want synthetic symbols without names anyway, so get rid of them. Also, simplify and correct sanity checks. PR 29677 * mach-o.c (bfd_mach_o_get_synthetic_symtab): Rewrite.
2022-09-14looping in bfd_mach_o_fat_openr_next_archived_fileAlan Modra1-4/+23
mach-o.c doesn't sanity check mach-o-fat archives, making it easy for fuzzers to create an archive with mach_o_fat_archentry headers that point to the same offset. bfd_mach_o_fat_openr_next_archived_file uses the previous element offset to find its header, and thus the next element. If two offsets are the same, any tool reading the archive will get stuck. This patch rejects such archives, and any with overlapping elements. * mach-o.c (overlap_previous): New function. (bfd_mach_o_fat_archive_p): Sanity check that elements do not overlap each other or the file and archive headers.
2022-08-06msan: bfd_mach_o_layout_commands use of uninitialised valueAlan Modra1-34/+44
Catches fuzzed input with unterminated strings that later run off the end of their buffers when calling strlen. * mach-o.c: Use size_t vars where approprite. (bfd_mach_o_alloc_and_read): Add "extra" param. Allocate that much extra and clear. Update all callers, those that set up strings with one extra byte.

2022-05-27Remove use of bfd_uint64_t and similarAlan Modra1-1/+1
Requiring C99 means that uses of bfd_uint64_t can be replaced with uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_* and tidies a few places that print 64-bit values.
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.
2022-01-01ubsan: bfd_mach_o_build_commands shift exponent 64 is too largeAlan Modra1-8/+8

2021-11-06ubsan: undefined shift in mach-o.cAlan Modra1-1/+1
This one was logically wrong too. If file_ptr was 64 bits, then -1U is extended to 0x00000000ffffffff, probably not what was intended here. * mach-o.c (FILE_ALIGN): Correct expression.

Section reloc_count is an unsigned int. Adding one for a NULL terminator to an array of arelent pointers can wrap the count to zero.

2021-03-29TRUE/FALSE simplificationAlan Modra1-1/+1
There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value. It's probably even a good idea to not rely on implicit conversion if bfd_boolean were _Bool. bfd/ * aoutx.h (aout_link_write_symbols): Don't cast boolean expression to bfd_boolean. * elf32-or1k.c (or1k_set_got_and_rela_sizes): Dont compare booleans against FALSE. * elf32-arc.c (name_for_global_symbol): Don't compare boolean to TRUE.

2020-05-20PR25993, read of freed memoryAlan Modra1-10/+7

2020-03-02bfd_cleanup for object_pAlan Modra1-6/+6
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.

2020-02-21Fuzzers whining about mach-o supportAlan Modra1-31/+105
It's very easy to make bfd/mach-o.c allocate huge amounts of memory with fuzzed binaries. This make it a little harder. The patch also fixes a number of places where an attempt to detect overflow of multiplication was done with code like if (x * 4 < x) /* overflow case */ That of course doesn't work. There are plenty of values of x that overflow x * 4 but (x * 4) mod 2^n is greater than x.

2019-09-19bfd_section_* macrosAlan Modra1-16/+15
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.

2019-03-12Don't use bfd_get_file_size in objdumpAlan Modra1-1/+14
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. The patch also fixes a number of other potential overflows by using the bfd_alloc2/malloc2/zalloc2 memory allocation functions. bfd/ * coffcode.h (buy_and_read): Delete unnecessary forward decl. Add nmemb parameter. Use bfd_alloc2. (coff_slurp_line_table): Use bfd_alloc2. Update buy_and_read calls. Delete assertion. (coff_slurp_symbol_table): Use bfd_alloc2 and bfd_zalloc2.
