* Add more NT_ARM_* constants from Linux kernel to elf.hJoseph Myers4 days1-0/+4
| | | | | | | | Linux 6.9 adds the ELF note type NT_ARM_FPMR. Add this to glibc's elf.h, along with the previously missed NT_ARM_SSVE, NT_ARM_ZA and NT_ARM_ZT (added in older kernel versions). Tested for x86_64.
* elf: add note identifier for dlopen metadataLuca Boccassi9 days1-0/+4
| | | | | | | | | | | | | | | | This new note type is defined at https://systemd.io/ELF_DLOPEN_METADATA/ and is used to list shared library dependencies loaded via dlopen(). Distro packagers can use this, via tools like those available at https://github.com/systemd/package-notes to automatically generate dependencies when building projects that make use of this specification. By defining the note id here we can use it in other projects as a stable identifier, for example in 'readelf' to pretty-print its content.

| | | | | | | | | This is mostly based on AArch64 and RISC-V implementation. Add R_LARCH_TLS_DESC32 and R_LARCH_TLS_DESC64 relocations. For _dl_tlsdesc_dynamic function slow path, temporarily save and restore all vector registers.
* powerpc: Add HWCAP3/HWCAP4 data to TCB for Power Architecture.Manjunath Matti2024-03-191-0/+4
| | | | | | | | | | | | | This patch adds a new feature for powerpc. In order to get faster access to the HWCAP3/HWCAP4 masks, similar to HWCAP/HWCAP2 (i.e. for implementing __builtin_cpu_supports() in GCC) without the overhead of reading them from the auxiliary vector, we now reserve space for them in the TCB. This is an ABI change for GLIBC 2.39. Suggested-by: Peter Bergner <bergner@linux.ibm.com> Reviewed-by: Peter Bergner <bergner@linux.ibm.com>

* elf: Add ELF_DYNAMIC_AFTER_RELOC to rewrite PLTH.J. Lu2024-01-051-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add ELF_DYNAMIC_AFTER_RELOC to allow target specific processing after relocation. For x86-64, add #define DT_X86_64_PLT (DT_LOPROC + 0) #define DT_X86_64_PLTSZ (DT_LOPROC + 1) #define DT_X86_64_PLTENT (DT_LOPROC + 3) 1. DT_X86_64_PLT: The address of the procedure linkage table. 2. DT_X86_64_PLTSZ: The total size, in bytes, of the procedure linkage table. 3. DT_X86_64_PLTENT: The size, in bytes, of a procedure linkage table entry. With the r_addend field of the R_X86_64_JUMP_SLOT relocation set to the memory offset of the indirect branch instruction. Define ELF_DYNAMIC_AFTER_RELOC for x86-64 to rewrite the PLT section with direct branch after relocation when the lazy binding is disabled. PLT rewrite is disabled by default since SELinux may disallow modifying code pages and ld.so can't detect it in all cases. Use $ export GLIBC_TUNABLES=glibc.cpu.plt_rewrite=1 to enable PLT rewrite with 32-bit direct jump at run-time or $ export GLIBC_TUNABLES=glibc.cpu.plt_rewrite=2 to enable PLT rewrite with 32-bit direct jump and on APX processors with 64-bit absolute jump at run-time.

| | | | | | | | | | | Now binutils use some E_MIPS_* macros and EF_MIPS_* macros, it is difficult to decide which style macro we should use when we want to add new ELF file header flags. IRIX used to use EF_MIPS_* macros and in elf/elf.h there also has comments "The following are unofficial names and should not be used".

| | | | | | | | | | | Linux 6.3 adds constants AT_RSEQ_FEATURE_SIZE and AT_RSEQ_ALIGN; add them to glibc's elf.h. (Recall that, although elf.h is a system-independent header, so far we've put AT_* constants there even if Linux-specific, as discussed in bug 15794. So rather than making any attempt to fix that issue, the new constants are just added there alongside the existing ones.) Tested for x86_64.

* riscv: Resolve symbols directly for symbols with STO_RISCV_VARIANT_CC.Hsiangkai Wang2023-04-281-0/+7
| | | | | | | | | | | | | | | | | | | | | In some cases, we do not want to go through the resolver for function calls. For example, functions with vector arguments will use vector registers to pass arguments. In the resolver, we do not save/restore the vector argument registers for lazy binding efficiency. To avoid ruining the vector arguments, functions with vector arguments will not go through the resolver. To achieve the goal, we will annotate the function symbols with STO_RISCV_VARIANT_CC flag and add DT_RISCV_VARIANT_CC tag in the dynamic section. In the first pass on PLT relocations, we do not set up to call _dl_runtime_resolve. Instead, we resolve the functions directly.

Therefore, this patch is to update ARC entries in elf/elf.h. The majority of the update is about adding new definitions, specially for the relocations. However, there is one rename, one deletion, and one change: - R_ARC_JUMP_SLOT renamed to R_ARC_JMP_SLOT to match binutils. - R_ARC_B26 removed because it is unused and deprecated. - R_ARC_TLS_DTPOFF_S9 changed from 0x4a to the correct value 0x49. Finally, a specific SHT class for ARC has been added to glibcelf.py. Else, it would result in a collision: _register_elf_h(Sht, ranges=True, File "/src/glibc/scripts/glibcelf.py", line x, in _register_elf_h raise ValueError('duplicate value {}: {}, {}'.format( ValueError: duplicate value 1879048193: SHT_ARC_ATTRIBUTES, SHT_X86_64_UNWIND [1] https://sourceware.org/pipermail/elfutils-devel/2022q4/005530.html [2] https://sourceware.org/pipermail/elfutils-devel/2022q4/005548.html No regression has been observed after applying this patch.

The marker must be added by programmers explicitly in one of 3 ways: 1. Pass -mneeded to GCC. 2. Add the marker in the linker inputs as this patch does. 3. Pass -z x86-64-v[234] to the linker. Add GNU_PROPERTY_X86_ISA_1_BASELINE and GNU_PROPERTY_X86_ISA_1_V[234] marker support to ld.so if binutils 2.32 or newer is used to build glibc: 1. Add GNU_PROPERTY_X86_ISA_1_BASELINE and GNU_PROPERTY_X86_ISA_1_V[234] markers to elf.h. 2. Add GNU_PROPERTY_X86_ISA_1_BASELINE and GNU_PROPERTY_X86_ISA_1_V[234] marker to abi-note.o based on the ISA level used to compile abi-note.o, assuming that the same ISA level is used to compile the whole glibc. 3. Add isa_1 to cpu_features to record the supported x86 ISA level. 4. Rename _dl_process_cet_property_note to _dl_process_property_note and add GNU_PROPERTY_X86_ISA_1_V[234] marker detection. 5.

* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* elf.h: fix spelling typos in commentsDmitry V. Levin2020-12-121-3/+3

* treewide: fix incorrect spelling of indices in commentsDmitry V. Levin2020-12-111-2/+2
| | | | | | Replace 'indeces' with 'indices', the most annoying of these typos were those found in elf.h which is a public header file copied to other projects.
* elf: Synchronize <elf.h> section header flags with binutilsFlorian Weimer2020-12-031-0/+2
| | | | | binutils 2.36 will add SHF_GNU_RETAIN support. SHF_GNU_BUILD_NOTE was also missing from the glibc header.
