* x86: Fix TEST_NAME to make it a string in tst-strncmp-rtm.cNoah Goldstein2022-02-181-2/+2
| | | | | | | | Previously TEST_NAME was passing a function pointer. This didn't fail because of the -Wno-error flag (to allow for overflow sizes passed to strncmp/wcsncmp) Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
* x86: Test wcscmp RTM in the wcsncmp overflow case [BZ #28896]Noah Goldstein2022-02-183-10/+48
| | | | | | | | | | | In the overflow fallback strncmp-avx2-rtm and wcsncmp-avx2-rtm would call strcmp-avx2 and wcscmp-avx2 respectively. This would have not checks around vzeroupper and would trigger spurious aborts. This commit fixes that. test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass on AVX2 machines with and without RTM. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
* hppa: Fix swapcontextJohn David Anglin2022-02-183-7/+58
| | | | | | | | | | | | | | | | | This change fixes the failure of stdlib/tst-setcontext2 and stdlib/tst-setcontext7 on hppa. The implementation of swapcontext in C is broken. C saves the return pointer (rp) and any non call-clobbered registers (in this case r3, r4 and r5) on the stack. However, the setcontext call in swapcontext pops the stack and subsequent calls clobber the saved registers. When the context in oucp is restored, both tests fault. Here we rewrite swapcontext in assembly code to avoid using the stack for register values that need to be used after restoration. The getcontext and setcontext routines are revised to save and restore register ret1 for normal returns. We copy the oucp pointer to ret1. This allows access to the old context after calling getcontext and setcontext.

* microblaze: Use the correct select syscall (BZ #28883)Adhemerval Zanella2022-02-161-1/+1
| | | | | | | | | On Microblaze only __NR_newselect is implemented, even though kernel advertise __NR_select on asm/unistd.h. Since microblaze is the only architecture that undef __ASSUME_PSELECT, the generic code change is simpler than chaging the architecture syscall number. Acked-by: Mark Hatle <mark.hatle@xilinx.com>

* 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.

* 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.

| | | | | | | | | Otherwise, <dl-auxv.h> on POWER ends up being included twice, once in dl-sysdep.c, once in dl-support.c.

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.
