2024-12-02aarch64: refactoring _bfd_aarch64_elf_link_setup_gnu_properties (part 2)Matthieu Longo1-9/+10
Simplify this for-loop with too many "break" instructions inside.
2024-12-02aarch64: refactoring _bfd_aarch64_elf_check_bti_reportMatthieu Longo3-11/+12
Before this patch, warnings were reported normally, and errors (introduced by a previous patch adding '-z bti-report' option) were logged as error but were not provoking a link failure. The root of the issue was a misuse of _bfd_error_handler to report the errors. Replacing _bfd_error_handler by info->callbacks->einfo, with the addition of the formatter '%X' for errors fixed the issue.
2024-12-02aarch64: refactoring _bfd_aarch64_elf_link_setup_gnu_properties (part 1)Matthieu Longo3-33/+41
Exposing the output GNU property as a parameter of _bfd_aarch64_elf_link_setup_gnu_properties seems to break the encapsulation. The output GNU property update should be part of the function that sets up the GNU properties. This patch removes the parameter, and perform the update of the GNU property on the output object inside the function.
2024-12-02aarch64: rename gnu_and_prop to gnu_property_aarch64_feature_1_andMatthieu Longo2-19/+19
2024-12-02aarch64: simplify condition in elfNN_aarch64_merge_gnu_propertiesMatthieu Longo1-4/+2
The current condition used to check if a GNU feature property is set on an input object before the merge is a bit confusing. (aprop && !<something about aprop>) || !aprop It seems easier to understand if it is changed as follows: (!aprop || !<something about aprop>)
2024-12-02aarch64: rename parameter of _bfd_aarch64_elf_merge_gnu_propertiesMatthieu Longo1-9/+9
The current naming of the AArch64 feature GNU property of the output bfd does not reflect what it is. This patch renames it from "prop" to "outprop".
2024-12-02aarch64: use only one type for feature marking reportMatthieu Longo3-19/+25
2024-12-02aarch64: group software protection options under a same struct.Matthieu Longo3-67/+88
- declare a new struc aarch_protection_opts to store all the configuration options related to software protections (i.e. bti-plt, pac-plt, bti-report level). - add a new option "-z bti-report" to configure the log level of reported issues when BTI PLT is forced. - encapsulate the BTI report inside _bfd_aarch64_elf_check_bti_report.

2024-12-01Re: PR32399, buffer overflow printing core_file_failing_commandAlan Modra6-21/+31
Fix more potential buffer overflows, and correct trad-code.c and cisco-core.c where they should be using bfd_{z}alloc rather than bfd_{z}malloc. To stop buffer overflows with fuzzed objects that don't have a terminator on the core_file_failing_command string, this patch allocates an extra byte at the end of the entire header buffer rather than poking a NUL at the end of the name array (u_comm[] or similar) because (a) it's better to not overwrite the file data, and (b) it is possible that some core files make use of fields in struct user beyond the end of u_comm to extend the command name. The patch also changes some unnecessary uses of bfd_zalloc to bfd_alloc. There's not much point in clearing memeory that will shortly be completely overwritten.

2024-11-29PR32399, buffer overflow printing core_file_failing_commandAlan Modra6-7/+12
Assorted targets do not check, as the ELF targets do, that the program name in a core file is NUL terminated. Fix some of them. I haven't attempted to fix all targets because editing host specific code can easily result in build bugs, which aren't discovered until someone build binutils for that host. (Of the files edited here, I can't easily compile hpux-core.c and osf-core.c on a linux system.)

2024-11-26nios2: Remove binutils support for Nios II target.Sandra Loosemore15-6461/+2
The Nios II architecture has been EOL'ed by the vendor. This patch removes all binutils, bfd, gas, binutils, and opcodes support for this target with the exception of the readelf utility. (The ELF EM_* number remains valid and the relocation definitions from the Nios II ABI will never change in future, so retaining the readelf support seems consistent with its purpose as a utility that tries to parse the headers in any ELF file provided as an argument regardless of target.)
2024-11-26PR32387 ppc64 TLS optimization bug with -fno-plt codeAlan Modra1-0/+9
The inline plt code emitted by gcc is incompatible with the linker/ld.so --tls-get-addr-optimize scheme. This is the runtime optimisation where the first call to __tls_get_addr results in __tls_get_addr updating the tls_index pair, then the special linker stub using that to short-circuit second and subsequent calls for a given tls symbol. Enabled by default when the linker sees __tls_get_addr_opt is preseent, and enabled in ld.so when DT_PPC64_OPT has PPC64_OPT_TLS set. Note that this is distinct from link-time tls optimisation. PR 32387 * elf64-ppc.c (ppc64_elf_check_relocs): Disable tls_get_addr_opt on detecting inline plt calls to __tls_get_addr.

2024-11-19LoongArch: Do not relax pcalau12i+ld.d when there is overflowLulu Cai1-5/+27
There is no overflow check for the relaxation of pcalau12i+ld.d => pcalau12i+addi.d. For instruction sequences that can be relaxed, they are directly relaxed to pcalau12i+addi.d. However, when the relative distance between the symbol and the pc exceeds the 32-bit range, the symbol value cannot be obtained correctly. Adds an overflow check for the relaxation of pcalau12i+ld.d. If it is found that the relaxation will overflow, it will not be relaxed.

2024-11-18ELF: SHF_STRINGS isn't really tied to SHF_MERGEJan Beulich1-2/+8
It's not overly useful without it, but the spec doesn't name any dependency between the two. People may want to use it for purely informational purposes, for example. Adjust, in particular, entity size processing to be engaged if either flag is set, as mandated by the spec.
