Hi LTP Team,
Test cases open14.c and openat03.c failed on arm64 on latest Linux kernel 4.9.x.
Have you noticed these failures on x86_64 and other architectures and
which kernel version ?
Test output:
-----------------
create multiple directories, link files into them
and check file permissions
file mode read 0, but expected
file mode read 0, but expected 7755
file mode read 0, but expected 1
file mode read 0, but expected 755
file mode read 0, but expected 644
file mode read 0, but expected 440
Linux version 4.9.0-rc6-00086-g3b404a5 (broonie@optimist) (gcc version
5.1.1 20150608 (Linaro GCC 5.1-2015.08) ) #1 SMP PREEMPT Tue Nov 22
04:14:54 GMT 2016
Test case is trimmed version of LTP,
you can find test case here in this link

There was a known glibc bug associated with these 2 tests, and also possible
issue with tmpfs, see this for details:

Do you mean this bug: https://sourceware.org/bugzilla/show_bug.cgi?id=17912 ?
We tested with the patch applied.

I tried it on x86, with recent upstream kernel on top of RHEL7.4,
with tmp directory backed by xfs and tmpfs, no failures here:

You example works too, with following change:
