Hello,

We ran automated tests on a recent commit from this kernel tree:

Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git
Commit: e37569e28eea - Merge branch 'for-next/late-arrivals' into for-kernelci

The results of these automated tests are provided below.

Overall result: FAILED (see details below)
Merge: OK
Compile: OK
Tests: FAILED

All kernel binaries, config files, and logs are available for download here:

https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/index.html?prefix=datawarehouse/2020/10/05/614774

One or more kernel tests failed:

    aarch64:
     ❌ LTP

We hope that these logs can help you find the problem quickly. For the full detail on our testing procedures, please scroll to the bottom of this message.

Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective.

Compile testing
---------------

We compiled the kernel for 1 architecture:

aarch64:

🚧 ✅ POSIX pjd-fstest suites
🚧 ✅ Firmware test suite
🚧 ✅ jvm - jcstress tests
🚧 ✅ Memory function: kaslr
🚧 ✅ Ethernet drivers sanity
🚧 ✅ Networking firewall: basic netfilter test 🚧 ✅ audit: audit testsuite test
🚧 ✅ trace: ftrace/tracer
🚧 ✅ kdump - kexec_boot

Test sources: https://gitlab.com/cki-project/kernel-tests
💚 Pull requests are welcome for new tests or improvements to existing tests!

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report.

Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed.

Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.

Hmm, this link doesn't seem to work (the '10' directory doesn't exist). Do I just need to wait a bit longer?

Cheers,

Thanks for reporting this!
There was a problem on the script that uploads the files. It's fixed now and the files are deploying. In a few minutes everything should be there.
Your report also made us realize the link is incorrect, as the prefix should be datawarehouse-public instead of datawarehouse (with the correct prefix it should link to the correct folder).

The (now working) link is the following:

Sorry for the troubles,

Thanks, that works now. It looks like the failure is in the timed semaphore tests:

semop03.c:55: TFAIL: unexpected failure: EAGAIN/EWOULDBLOCK (11)

where the text expects EINTR, but assumedly the timeout is kicking in so we get EAGAIN. I don't see how the arm64 tree can be causing that, and I rather suspect that the test is just racy (the timeout is pretty small -- 10ms iiuc).

It also looks like this test was only added to LTP in September, so that would explain why it appears to be a new failure.

Will

That is one possible explanation for sure.

Rachel, can you please increase the timeout to something sufficiently big enough and try again ? Something like this:

- tst_ts_set_sec(&timeout, 0);
+ tst_ts_set_sec(&timeout, 2);

I saw similar issues with very small timeouts and 10ms kind of worked all the time. I think we need to increase it further.

Thanks for your patch Viresh, just ran it on the same machine/kernel for 100 loops, and happy to confirm I no longer see the failures, increasing the timeout worked well.

Thanks!
Rachel
