2024-04-18alpha_vms_get_section_contents vs. fuzzed filesAlan Modra1-24/+26
This patch is in response to an oss-fuzz report regarding use-of-uninitialized-value in bfd_is_section_compressed_info from section contents provided by alpha_vms_get_section_contents. That hole is covered by using bfd_zalloc rather than bfd_alloc. The rest of the patch is mostly a tidy. In a function returning section contents, I tend to prefer a test on the section properties over a test on file properties. That's why I've changed the file flags test to one on section filepos and flags before calling _bfd_generic_get_section_contents. Also, fuzzed objects can easily have sections with file backing in relocatable objects, or sections without file backing in images. Possible confusion is avoided by testing each section. Note that we are always going to run into out-of-memory with fuzzed alpha-vms object files due to sections with contents via ETIR records. eg. ETIR__C_STO_IMMR stores a number of bytes repeatedly, with a 32-bit repeat count. So section contents can be very large from a relatively small file. I'm inclined to think that an out-of-memory error is fine for such files. * vms-alpha.c (alpha_vms_get_section_contents): Handle sections with non-zero filepos or without SEC_HAS_CONTENTS via _bfd_generic_get_section_contents. Zero memory allocated for sections filled by ETIR records.

While the patch that Nick reverted in commit 3f6a060c7543 was in the source, "FAIL: objcopy executable (pr25662)" was seen on ARC. The failure was triggered by the .ARC.attributes section being removed by the linker script. When a file lacking this section is copied by objcopy, e_flags from the input is copied to the output (in this case the value 0x406), but arc_elf_final_write_processing then logical-ors in 0x300 when Tag_ARC_ABI_osver is not found. * elf32-arc.c (arc_elf_final_write_processing): Don't ignore existing e_flags for objcopy.
2024-04-16Avoid cache race in bfd_check_format_matchesTom Tromey5-5/+109
Running the gdb test suite with the thread sanitizer enabled shows a race when bfd_check_format_matches and bfd_cache_close_all are called simultaneously on different threads. This patch fixes this race by having bfd_check_format_matches temporarily remove the BFD from the file descriptor cache -- leaving it open while format-checking proceeds. In this setup, the BFD client is responsible for closing the BFD again on the "checking" thread, should that be desired. gdb does this by calling bfd_cache_close in the relevant worker thread. An earlier version of this patch omitted the "possibly_cached" helper function. However, this ran into crashes in the binutils test suite involving the archive-checking abort in bfd_cache_lookup_worker. I do not understand the purpose of this check, so I've simply had the new function work around it. I couldn't find any comments explaining this situation, either. I suspect that there may still be races related to this case, but I don't think I have access to the platforms where gdb deals with archives.

2024-04-16Thread-safety improvements for bfd_check_format_matchesTom Tromey4-121/+183
A gdb bug found that bfd_check_format_matches has some data races when called from multiple threads. In particular, it changes the BFD error handler, which is a global. It also has a local static variable ("in_check_format") that is used for recursion detection. And, finally, it may emit warnings to the per-xvec warning array, which is a global. This patch removes all the races here. The first part of patch is to change _bfd_error_handler to directly handle the needs of bfd_check_format_matches. This way, the error handler does not need to be changed. This change lets us use the new per-thread global (error_handler_messages, replacing error_handler_bfd) to also remove the need for in_check_format -- a single variable suffices. Finally, the global per-xvec array is replaced with a new type that holds the error messages. The outermost such type is stack-allocated in bfd_check_format_matches. I tested this using the binutils test suite. I also built gdb with thread sanitizer and ran the test case that was noted as failing. Finally, Alan sent me the test file that caused the addition of the xvec warning code in the first place, and I confirmed that "nm-new" has the same behavior on this file both before and after this patch.

2024-04-11Remove bfdwin.cAlan Modra39-629/+55
In commit b86d3af60ffc and 0ab0435fe672 I fixed SIGBUS errors found by oss-fuzz now that --with-mmap defaults to enabled. It turns out there are further problems with the aout mmap code: aout_read_minisymbols returns the external symbol array, which is later freed by nm.c. If the array is mmaped you can't free it. Now this could be fixed by making aout minisymbols an array of pointers, but I figure there's not much point in expending effort on that. So delete the aout mmap support along with bfdwin.c and get_section_contents_in_window.

So moving the string comparison earlier would work. However, we've already looked up inh in the first case so can dispense with name comparisons.
