* elf: Add new LoongArch reloc types (110 to 126) into elf.hXi Ruoyao2024-02-221-0/+17

* 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.

* MIPS: Add ELF file header flagsYing Huang2023-09-271-1/+47
| | | | | | | | | | | 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". So we should use EF_MIPS_* to keep same style with the beginning. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

(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.

* 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.

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.

* Make elf.h header self contained.Érico Rolim2020-10-281-6/+0
| | | | | | | | | | | | The elf/elf.h header is shared, verbatim, by the elfutils project. However, elfutils can be used on systems with libcs other than glibc, making the presence of __BEGIN_DECLS, __END_DECLS and <features.h> in the file something that downstream distros may have to add patches for. Furthermore, this file doesn't declare anything with language linkage, so `extern "C" {}` blocks aren't necessary; it also doesn't have any conditional definitions based on feature test macros, making inclusion of features.h unnecessary.
* elf.h: Add aarch64 bti/pac dynamic tag constantsMark Wielaard2020-09-071-0/+2
| | | | | | | | Constants double checked against binutils and the ELF for the Arm 64-bit Architecture (AArch64) Release 2020Q2 document. Only BTI PLT is used in glibc, there's no PAC PLT with glibc, and people are expected to use BIND_NOW.
* elf.h: add aarch64 property definitionsSzabolcs Nagy2020-05-211-0/+6
| | | | | | | These property values are specified by the AArch64 ELF ABI and binutils can create binaries marked with them. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* elf.h: Add PT_GNU_PROPERTYSzabolcs Nagy2020-05-211-0/+1
