2024-04-25LoongArch: The symbol got type can only be obtained after initializationLulu Cai1-1/+8
When scanning relocations and determining whether TLS type transition is possible, it will try to obtain the symbol got type. If the symbol got type record has not yet been allocated space and initialized, it will cause ld to crash. So when uninitialized, the symbol is set to GOT_UNKNOWN.

2024-04-23ignore some symbols in elf.c:swap_out_symsAlan Modra1-55/+48
The reason behind this patch was noticing that generic ELF targets fail to remove "bar" in the recently committed ld-elf/undefweak-1 test. (Despite that, those targets pass the test due to it being too strict when matching symbols. "bar" gets turned into a local weak defined absolute symbol.) swap_out_syms currently drops local section syms that are defined in discarded sections. Extend that to also drop other symbols in discarded sections too, even global symbols. The linker goes to quite a lot of effort to ensure globals in discarded section take a definition from the kept linkonce or comdat group section. So the global sym change should only affect cases where something is quite wrong about the set of linkonce or comdat group sections. However that change to elf_map_symbols meant we dropped _DYNAMIC_LINK / _DYNAMIC_LINKING for mips, a global absolute symbol given STT_SECTION type for some reason. That problem is fixed by reverting the pr14493 change which is no longer needed due to a) BSF_SECTION_SYM_USED on x86, and b) fixing objcopy to use copy_private_symbol_data. bfd/ PR 14493 * elf.c (ignore_sym): Rename from ignore_section_sym. Return true for any symbol without a section or in a discarded section. Revert pr14493 change. (elf_map_symbols): Tidy. Use ignore_sym on all symbols. (swap_out_syms): Tidy. ld/ * testsuite/ld-elf/undefweak-1.rd: Match any "bar".
2024-04-23copy_private_symbol_dataAlan Modra1-2/+2
bfd_copy_private_symbol_data is a bfd function that appeared in commit 89665c8562da a long time ago, but seemingly wasn't used anywhere until Jan added it to gas/symbols.c in commit 6a2b6326c21e. The function is used to modify ELF symbol st_shndx for symbols defined in odd sections like .symtab, so that they get the corresponding section st_shndx in an output file. This patch fixes some bitrot in the function. After commit c03551323c04 which introduced output_elf_obj_tdata, elf_strtab_sec and elf_shstrtab_sec will segfault if used on an input bfd. PR 14493 * elf.c (_bfd_elf_copy_private_symbol_data): Don't use elf_strtab_sec and elf_shstrtab_sec.

2024-04-18elf: Strip unreferenced weak undefined symbolsH.J. Lu3-28/+47
Linker will resolve an undefined symbol only if it is referenced by relocation. Unreferenced weak undefined symbols serve no purpose. Weak undefined symbols appear in the dynamic symbol table only when they are referenced by dynamic relocation.

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.

2024-04-17ARC e_flags vs. objcopyAlan Modra1-6/+6
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.
