* x86: Fix bug in strncmp-evex and strncmp-avx2 [BZ #28895]Noah Goldstein2022-02-162-0/+2
| | | | | | | | | | | | | Logic can read before the start of `s1` / `s2` if both `s1` and `s2` are near the start of a page. To avoid having the result contimated by these comparisons the `strcmp` variants would mask off these comparisons. This was missing in the `strncmp` variants causing the bug. This commit adds the masking to `strncmp` so that out of range comparisons don't affect the result. test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass as well a full xcheck on x86_64 linux.

* htl: Make pthread_[gs]etspecific not check for key validitySamuel Thibault2022-02-142-4/+2
| | | | | | | Since __pthread_key_create might be concurrently reallocating the __pthread_key_destructors array, it's not safe to access it without the mutex held. Posix explicitly says we are allowed to prefer performance over error detection.

* Fix elf/tst-audit2 on hppaJohn David Anglin2022-02-141-14/+10
| | | | | | | | | | | | The test elf/tst-audit2 fails on hppa with a segmentation fault in the long branch stub used to call malloc from calloc. This occurs because the test is not a PIC executable and calloc is called from the dynamic linker before the dp register is initialized in _dl_start_user. The fix is to move the dp register initialization into elf_machine_runtime_setup. Since the address of $global$ can't be loaded directly, we continue to use the DT_PLTGOT value from the the main_map to initialize dp.

* Linux: Include <dl-auxv.h> in dl-sysdep.c only for SHAREDFlorian Weimer2022-02-111-1/+2
| | | | | | | | | Otherwise, <dl-auxv.h> on POWER ends up being included twice, once in dl-sysdep.c, once in dl-support.c. That leads to a linker failure due to multiple definitions of _dl_cache_line_size. Fixes commit d96d2995c1121d3310102afda2deb1f35761b5e6 ("Revert "Linux: Consolidate auxiliary vector parsing").
* Revert "Linux: Consolidate auxiliary vector parsing"Florian Weimer2022-02-115-102/+104
| | | | | | | | | | | | This reverts commit 8c8510ab2790039e58995ef3a22309582413d3ff. The revert is not perfect because the commit included a bug fix for _dl_sysdep_start with an empty argv, introduced in commit 2d47fa68628e831a692cba8fc9050cef435afc5e ("Linux: Remove DL_FIND_ARG_COMPONENTS"), and this bug fix is kept. The revert is necessary because the reverted commit introduced an early memset call on aarch64, which leads to crash due to lack of TCB initialization.

* hppa: Fix bind-now audit (BZ #28857)Adhemerval Zanella2022-02-091-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | On hppa, a function pointer returned by la_symbind is actually a function descriptor has the plabel bit set (bit 30). This must be cleared to get the actual address of the descriptor. If the descriptor has been bound, the first word of the descriptor is the physical address of theA function, otherwise, the first word of the descriptor points to a trampoline in the PLT. This patch also adds a workaround on tests because on hppa (and it seems to be the only ABI I have see it), some shared library adds a dynamic PLT relocation to am empty symbol name: $ readelf -r elf/tst-audit25mod1.so [...] Relocation section '.rela.plt' at offset 0x464 contains 6 entries: Offset Info Type Sym.Value Sym. Name + Addend 00002008 00000081 R_PARISC_IPLT 508 [...] It breaks some assumptions on the test, where a symbol with an empty name ("") is passed on la_symbind. Checked on x86_64-linux-gnu and hppa-linux-gnu.

* linux: fix accuracy of get_nprocs and get_nprocs_conf [BZ #28865]Dmitry V. Levin2022-02-071-31/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | get_nprocs() and get_nprocs_conf() use various methods to obtain an accurate number of processors. Re-introduce __get_nprocs_sched() as a source of information, and fix the order in which these methods are used to return the most accurate information. The primary source of information used in both functions remains unchanged. This also changes __get_nprocs_sched() error return value from 2 to 0, but all its users are already prepared to handle that.

| | | | | | | | | | | | | | | | | | | | | | | | | No bug. Split vec generation into multiple steps. This allows the broadcast in AVX2 to use 'xmm' registers for the L(less_vec) case. This saves an expensive lane-cross instruction and removes the need for 'vzeroupper'. For SSE2 replace 2x 'punpck' instructions with zero-idiom 'pxor' for byte broadcast.
