* x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker [BZ #26717]H.J. Lu2021-01-071-20/+15

Lu <hjl.tools@gmail.com> Date: Fri Oct 30 06:49:57 2020 -0700 x86: Support GNU_PROPERTY_X86_ISA_1_BASELINE marker and commit 32930e4edbc06bc6f10c435dbcc63131715df678 Author: H.J. 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]$
* 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: Remove SHF_GNU_BUILD_NOTE.Mark Wielaard2020-12-121-1/+0

* 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

* 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).

* PowerPC64 ELFv2 PPC64_OPT_LOCALENTRYAlan Modra2017-06-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ELFv2 functions with localentry:0 are those with a single entry point, ie. global entry == local entry, that have no requirement on r2 or r12 and guarantee r2 is unchanged on return. Such an external function can be called via the PLT without saving r2 or restoring it on return, avoiding a common load-hit-store for small functions. This patch implements the ld.so changes necessary for this optimization. ld.so needs to check that an optimized plt call sequence is in fact calling a function implemented with localentry:0, end emit a fatal error otherwise. The elf/testobj6.c change is to stop "error while loading shared libraries: expected localentry:0 `preload'" when running elf/preloadtest, which we'd get otherwise. * elf/elf.h (PPC64_OPT_LOCALENTRY): Define. * sysdeps/alpha/dl-machine.h (elf_machine_fixup_plt): Add refsym and sym parameters.

* elf/elf.h: Add new 386 and X86_64 relocations from binutils.Mark Wielaard2016-02-191-3/+12
| | | | | | | | | | | | | | | | | | | | | | | The following new 386 and X86_64 were added to binutils. They are non-dynamic relocations, so don't need direct handling in glibc. But other programs, like elfutils, use the glibc elf.h definitions for the names and numbers when inspecting ET_REL files. R_386_GOT32X was proposed in https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX were proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 There also used to be R_X86_64_PC32_BND and R_X86_64_PLT32_BND but those already got deprecated in https://groups.google.com/d/msg/x86-64-abi/-hdQyMixt8Y/XFDOvioG85cJ * elf/elf.h (R_386_GOT32X): New.
