LTS testing with latest kselftests - some failures

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Greg, Shuah,

While testing 4.4.y and 4.9.y LTS kernels with latest kselftest, we
found a couple more test failures due to test-kernel mismatch:

1. firmware tests: - linux 4.5 [1] and 4.10 [2] added a few updates to
tests, and related updates to lib/test_firmware.c to improve the
tests. Stable-4.4 misses these patches to lib/test_firmware.c. Stable
4.9 misses the second update.

2. Bitmap test - test got added in 4.5, fails if test_bitmap.ko isn't present.

3. 'seccomp ptrace hole closure' patches got added in 4.7 [3] -
feature and test together.
- This one also seems like a security hole being closed, and the
'feature' could be a candidate for stable backports, but Arnd tried
that, and it was quite non-trivial. So perhaps  we'll need some help
from the subsystem developers here.

For all the 3 listed above, we will try and update the tests to gracefully exit.


4. bpf tests: These seem to have build failures in mainline as well -
I also tried to build kselftest-next, but a simple 'make -C
tools/testing/selftests/bpf' seems to error out. Are there any special
instructions to build these? [I tried x86_64, arm64 cross-compile on x86_64]


I will also individually request subsystem authors / mailing lists for
each of these towards help in improving these tests if required, but
wanted to use this thread as a converging point.

Thanks and Best regards,
Sumit.
