Bug Description

[Impact]
The pmtu.sh test in net from ubuntu_kernel_selftests will be marked
as failed even there is no obvious failure message from the test:

This is because the test script treats all non-zero return code as a
failure, thus it will be marked as FAILED when some sub-test got
skipped.

[Fix]
* ef1220a7d4bbdb selftests: pmtu.sh: use $ksft_skip for skipped return
 code
* 2a9d3716b810a4 selftests: pmtu.sh: improve the test result processing

This patchset will:
  1. Use the kselftest framework skip code $ksft_skip to replace the
     hardcoded SKIP return code.
  2. Improve the result processing, the test will be marked as PASSED
     if nothing goes wrong and not all the tests were skipped.

These have already landed in newer releases and this test does not
exist in B, thus we just need this for F/F-OEM-5.6/F-OEM-5.10/G.

The first patch needs to be backported (except on F-OEM-5.10) as some
test cases were not added yet.
The second one can be cherry-picked.

[Test]
Run this test directly on a patched kernel. The skipped test will cause
failure to this test.

[Where problems could occur]
Changes limited to testing tools, it's unlikely to cause any problem
to kernel functions.

Probably a test case issue.

This is not a regression as I can reproduce this on Bionic 5.4.0-1019-oracle as well

My apologies, I failed to apply the second patch (2a9d3716b810a4 selftests: pmtu.sh: improve the test result processing) to Focal and Groovy while applying this patchset from the mailing-list.

The verification with the partial fix was successful because on neither of these series we have skipped testcases, however, pmtu.sh is still failing in bionic/linux-hwe-5.4 because some features are not available and some tests are skipped:

https://autopkgtest.ubuntu.com/results/autopkgtest-bionic/bionic/amd64/l/linux-hwe-5.4/20210703_113537_4ed63@/log.gz

I have just applied the second patch to focal/linux and groovy/linux. I'll reset the status for these two kernels.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
