* S390: Also check vector support in memmove ifunc-selector [BZ #27511]Stefan Liebler2021-03-264-6/+15
| | | | | | | | | | | | | | | The arch13 memmove variant is currently selected by the ifunc selector if the Miscellaneous-Instruction-Extensions Facility 3 facility bit is present, but the function is also using vector instructions. If the vector support is not present, one is receiving an operation exception. Therefore this patch also checks for vector support in the ifunc selector and in ifunc-impl-list.c. Just to be sure, the configure check is now also testing an arch13 vector instruction and an arch13 Miscellaneous-Instruction-Extensions Facility 3 instruction.
* Support for multiple versions in versioned_symbol, compat_symbolFlorian Weimer2021-03-252-3/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This essentially folds compat_symbol_unique functionality into compat_symbol. This change eliminates the need for intermediate aliases for defining multiple symbol versions, for both compat_symbol and versioned_symbol. Some binutils versions do not suport multiple versions per symbol on some targets, so aliases are automatically introduced, similar to what compat_symbol_unique did. To reduce symbol table sizes, a configure check is added to avoid these aliases if they are not needed. The new mechanism works with data symbols as well as function symbols, due to the way an assembler-level redirect is used. It is not compatible with weak symbols for old binutils versions, which is why the definition of __malloc_initialize_hook had to be changed. This is not a loss of functionality because weak symbols do not matter to dynamic linking. The placeholder symbol needs repeating in nptl/libpthread-compat.c now that compat_symbol is used, but that seems more obvious than introducing yet another macro. A subtle difference was that compat_symbol_unique made the symbol global automatically. compat_symbol does not do this, so static had to be removed from the definition of __libpthread_version_placeholder.

* Change how the symbol_version_reference macro is definedFlorian Weimer2021-03-251-0/+38
| | | | | | | | | | | | A subsequent change will require including <config.h> for defining symbol_version_reference. <libc-symbol.h> should not include <config.h> for _ISOMAC, so it cannot define symbol_version_reference anymore, but symbol_version_reference is needed <shlib-compat.h> even for _ISOMAC. Moving the definition of symbol_version_reference to a separate file <libc-symver.h> makes it possible to use a single definition for both cases.

* hurd: handle EINTR during critical sectionsSamuel Thibault2021-03-2322-2/+102
| | | | | | | | | During critical sections, signal handling is deferred and thus RPCs return EINTR, even if SA_RESTART is set. We thus have to restart the whole critical section in that case. This also adds HURD_CRITICAL_UNLOCK in the cases where one wants to break the section in the middle.
* tst: Add test for sigtimedwaitLukasz Majewski2021-03-232-1/+63
| | | | | | | | | | | | | This change adds new test to assess sigtimedwait's timeout related functionality - the sigset_t is configured for SIGUSR1, which will not be triggered, so sigtimedwait just waits for timeout. To be more specific - two use cases are checked: - if sigtimedwait times out immediately when passed struct timespec has zero values of tv_nsec and tv_sec. - if sigtimedwait times out after timeout specified in passed argument Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* io: Return UNSUPPORTED if filesystem do not support 64 bit timestampsAdhemerval Zanella2021-03-123-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Linux filesystems might not fully support 64 bit timestamps [1], which make some Linux specific tests to fail when they check for the functionality. This patch adds a new libsupport function, support_path_support_time64, that returns whether the target file supports or not 64 bit timestamps. The support is checked by issuing a utimensat and verifying both the last access and last modification time against a statx call. The tests that might fail are also adjusted to check the file support as well: $ dd if=/dev/zero of=loopbackfile.img bs=100M count=1 1+0 records in 1+0 records out 104857600 bytes (105 MB, 100 MiB) copied, 0,0589568 s, 1,8 GB/s $ sudo losetup -fP loopbackfile.img $ mkfs.xfs loopbackfile.img meta-data=loopbackfile.img isize=512 agcount=4, agsize=6400 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=1 data = bsize=4096 blocks=25600, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=1368, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 $ mkdir loopfs $ sudo mount -o loop /dev/loop0 loopfs/ $ sudo chown -R azanella:azanella loopfs $ TMPDIR=loopfs/ ./testrun.sh misc/tst-utimes error: ../sysdeps/unix/sysv/linux/tst-utimes.c:55: File loopfs//utimesfECsK1 does not support 64-bit timestamps [1] https://bugzilla.redhat.com/show_bug.cgi?id=1795576
