* arm: Fix an incorrect check in ____longjmp_chk [BZ #27709]Szabolcs Nagy2021-04-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | An incorrect check in __longjmp_chk could fail on valid code causing FAIL: debug/tst-longjmp_chk2 The original check was altstack_sp + altstack_size - setjmp_sp > altstack_size i.e. sp at setjmp was outside of the altstack range. Here we know that longjmp is called from a signal handler on the altstack (SS_ONSTACK), and that it jumps in the wrong direction (sp decreases), so the check wants to ensure the jump goes to another stack. The check is wrong when altstack_sp == setjmp_sp which can happen when the altstack is a local buffer in the function that calls setjmp, so the patch allows == too. This fixes bug 27709. Note that the generic __longjmp_chk check seems to be different. (it checks if longjmp was on the altstack but does not check setjmp, so it would not catch incorrect longjmp use within the signal handler).
* Fix conform linknamespace tests due to gnu_dev_makedevStefan Liebler2021-03-311-2/+2
| | | | | | | | | | | | | | | | | If building on s390 / i686 with -Os, various conformance tests are failing with e.g. conform/ISO/assert.h/linknamespace.out: [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __getcwd -> [libc.a(getcwd.o)] __fstatat64 -> [libc.a(fstatat64.o)] gnu_dev_makedev The usage of gnu_dev_makedev was recently introduced by usage of the makedev makro in commit: 5b980d4809913088729982865188b754939bcd39 linux: Use statx for MIPSn64 This patch is now linking against __gnu_dev_makedev as also done in commit: 8b4a118222c7ed41bc653943b542915946dff1dd Fix -Os gnu_dev_* linknamespace, localplt issues (bug 15105, bug 19463).

* linux: Add y2106 support on utimensat testsAdhemerval Zanella2021-03-294-166/+119
| | | | | | | | | | | | The tests are refactored to use a common skeleton that handles whether the underlying filesystem supports 64 bit time, skips 64 bit time tests when the TU only supports 32 bit, and also skip 64 bit time tests larger than 32 unsigned int (y2106) if the system does not support it (MIPSn64 on kernels without statx support). Checked on x86_64-linux-gnu and i686-linux-gnu. I also checked on a mips64el-linux-gnu with 4.1.4 and 5.10.0-4-5kc-malta kernel to verify if the y2106 are indeed skipped.
* linux: Use statx for MIPSn64Adhemerval Zanella2021-03-293-33/+29
| | | | | | | | | | | MIPSn64 kernel ABI for legacy stat uses unsigned 32 bit for second timestamp, which limits the maximum value to y2106. This patch make mips64 use statx as for 32-bit architectures. Thie __cp_stat64_t64_statx is open coded, its usage is solely on fstatat64 and it avoid the need to redefine the name for mips64 (which will call __cp_stat64_statx since its does not use __stat64_t64 internally).
* linux: Disable fstatat64 fallback if __ASSUME_STATX is definedAdhemerval Zanella2021-03-291-16/+40
| | | | | | | | | | | | If the minimum kernel supports statx there is no need to call the fallback stat legacy syscalls. The statx is also called on compat xstat syscall, but different than the fstatat it calls no fallback and it is assumed to be always present. Checked on powerpc-linux-gnu (with and without --enable-kernel=4.11) and on powerpc64-linux-gnu.
* linux: Implement fstatat with __fstatat64_time64Adhemerval Zanella2021-03-291-38/+11
| | | | | | | | | It makes fstatat use __NR_statx, which fix the s390 issue with missing nanoxsecond support on compat stat syscalls (at least on recent kernels) and limits the statx call to only one function (which simplifies the __ASSUME_STATX support). Checked on i686-linux-gnu and on powerpc-linux-gnu.

* 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
