* 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>

* Build get-cpuid-feature-leaf.c without stack-protector [BZ #27555]Siddhesh Poyarekar2021-03-152-0/+4
| | | | | | | | | | | | | | | __x86_get_cpuid_feature_leaf is called during early startup, before the stack check guard is initialized and is hence not safe to build with stack-protector. Additionally, IFUNC resolvers for static tst-ifunc-isa tests get called too early for stack protector to be useful, so fix them to disable stack protector for the resolver functions. This fixes all failures seen with --enable-stack-protector=all configuration. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* posix: Consolidate register-atforkAdhemerval Zanella2021-03-125-81/+25
| | | | | | | | | | | | | Both htl and nptl uses a different data structure to implement atfork handlers. The nptl one was refactored by 27761a1042d to use a dynarray which simplifies the code. This patch moves the nptl one to be the generic implementation and replace Hurd linked one. Different than previous NPTL, Hurd also uses a global lock, so performance should be similar. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for i686-gnu.

* 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

* nss: fix nss_database_lookup2's alternate handling [BZ #27416]DJ Delorie2021-03-091-3/+1
| | | | | | | | | | | | | | | | | | | | __nss_database_lookup2's extra arguments were left unused in the nsswitch reloading patch set; this broke compat (default config ignored) and shadow files (secondary name ignored) which relies on these fallbacks. This patch adds in the previous behavior by correcting the initialization of the database list to reflect the fallbacks. This means that the nss_database_lookup2 interface no longer needs to be passed the fallback info, so API and callers were adjusted. Since all callers needed to be edited anyway, the calls were changed from __nss_database_lookup2 to the faster __nss_database_get. This was an intended optimization which was deferred during the initial lookup changes to avoid touching so many files. The test case verifies that compat targets work (passwd) and that the default configuration works (group). Tested on x86-64.
