Lu <hjl.tools@gmail.com> Date: Fri Oct 9 05:05:57 2020 -0700 x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker GNU_PROPERTY_X86_ISA_1_NEEDED property in x86 ELF binaries indicate the micro-architecture ISA level required to execute the binary. 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 _rtld_main_check and _dl_open_check to check loaded objects with the incompatible ISA level. 6. Add a testcase to verify that dlopen an x86-64-v4 shared object fails on lesser platforms. 7. Use <get-isa-level.h> in dl-hwcaps-subdirs.c and tst-glibc-hwcaps.c. Tested under i686, x32 and x86-64 modes on x86-64-v2, x86-64-v3 and x86-64-v4 machines. Marked elf/tst-isa-level-1 with x86-64-v4, ran it on x86-64-v3 machine and got: [hjl@gnu-cfl-2 build-x86_64-linux]$ ./elf/tst-isa-level-1 ./elf/tst-isa-level-1: CPU ISA level is lower than required [hjl@gnu-cfl-2 build-x86_64-linux]$

* 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.

* MIPS support for GNU hashMihailo Stojanovic2019-08-291-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a reimplementation of [1], which was submitted back in 2015. Copyright issue has been sorted [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (GT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering of the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word at the beggining of the section, which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue reported in [3] which is caused by the leading word of the .MIPS.xhash section. Leading word is now removed in the corresponding binutils patch, and the number of entries in the translation table is computed using DT_MIPS_SYMTABNO dynamic tag. Since the MIPS specific dl-lookup.c file was removed following the initial patch submission, I opted for the definition of three new macros in the generic ldsodefs.h. ELF_MACHINE_GNU_HASH_ADDRIDX defines the index of the dynamic tag in the l_info array. ELF_MACHINE_HASH_SYMIDX is used to calculate the index of a symbol in GNU hash. On MIPS, it is defined to look up the symbol index in the translation table. ELF_MACHINE_XHASH_SETUP is defined for MIPS only. It initializes the .MIPS.xhash pointer in the link_map_machine struct. The other major change is bumping the highest EI_ABIVERSION value for MIPS to suggest that the dynamic linker now supports GNU hash. The patch was tested by running the glibc testsuite for the three MIPS ABIs (o32, n32 and n64) and for x86_64-linux-gnu.

* Add elf.h NT_* macros from Linux 4.15 (bug 14890).Joseph Myers2018-02-061-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux 4.15 adds NT_S390_RI_CB to linux/elf.h (and NT_ARM_SVE, which we already have in glibc). This shows up that various other ELF note values from linux/elf.h are missing from glibc's elf.h. This patch adds the missing values that are relevant to glibc architectures. As elf.h is a general description of the ELF format, not necessarily limited to glibc configurations, there's an argument for having the remaining NT_* values that Linux uses for non-glibc architectures in glibc's elf.h as well, but this patch does not add them. Adding the NT_PRFPREG name is bug 14890. That bug also requests making the NT_FPREGSET name obsolete. Given that elf.h is not just for Linux but can describe ELF for other operating systems, I don't think that a change of name in the Linux kernel is sufficient justification for declaring the other name obsolete; there can be multiple names for the same note value, even with incompatible semantics, if those reflect variants of the ELF format in actual use. For example, FreeBSD appears still to have the name NT_FPREGSET <https://github.com/freebsd/freebsd/blob/master/sys/sys/elf_common.h> (note: I haven't checked whether the FreeBSD kernel actually generates such notes or whether this is actually an other-OS definition present in FreeBSD's header). [BZ #14890] * elf/elf.h (NT_PRFPREG): New macro. (NT_S390_VXRS_LOW): Likewise. (NT_S390_VXRS_HIGH): Likewise. (NT_S390_GS_CB): Likewise. (NT_S390_GS_BC): Likewise. (NT_S390_RI_CB): Likewise.
* Add DT_SYMTAB_SHNDX from gABIH.J. Lu2018-02-051-1/+2
| | | | | * elf/elf.h (DT_SYMTAB_SHNDX): New. Set to 34. (DT_NUM): Updated to 35.
* Add support for the RISC-V-specific ELF flagsPalmer Dabbelt2018-01-251-0/+8
| | | | | | | | | | | | | | | | | | | | The RISC-V port defines ELF flags that enforce compatibility between various objects. This adds the shared support necessary for these flags. 2018-01-25 Palmer Dabbelt <palmer@sifive.com> * elf/cache.c (print_entry): Add FLAG_RISCV_FLOAT_ABI_SOFT and FLAG_RISCV_FLOAT_ABI_DOUBLE. * elf/elf.h (EF_RISCV_RVC): New define. (EF_RISCV_FLOAT_ABI): Likewise. (EF_RISCV_FLOAT_ABI_SOFT): Likewise. (EF_RISCV_FLOAT_ABI_SINGLE): Likewise. (EF_RISCV_FLOAT_ABI_DOUBLE): Likewise. (EF_RISCV_FLOAT_ABI_QUAD): Likewise. * sysdeps/generic/ldconfig.h (FLAG_RISCV_FLOAT_ABI_SOFT): New define. (FLAG_RISCV_FLOAT_ABI_DOUBLE): Likewise.
* Add NT_ARM_SVE to elf.hAlan Hayward2018-01-151-0/+2
| | | | | | This definition is for AArch64 SVE registers in elf core dumps. * elf/elf.h (NT_ARM_SVE): Define.
* Synchronize DF_1_* flags with binutils (Bug 22707)Carlos O'Donell2018-01-131-0/+2
| | | | | | | | | | This patch synchronizes DF_1_* flags with binutils and ensures that all DF_1_* flags defined in binutil's include/elf/common.h are also defined glibc's elf/elf.h. This is a user visible change since elf/elf.h is installed by default as /usr/include/elf.h. Signed-off-by: Carlos O'Donell <carlos@redhat.com>
* Add RISC-V dynamic relocations to elf.hPalmer Dabbelt2018-01-061-0/+14
| | | | | | | | | | | | | | | | | | | These relocations can appear in shared objects on RISC-V ELF systems. 2018-01-06 Palmer Dabbelt <palmer@sifive.com> * elf/elf.h (R_RISCV_NONE): New define.
