Title:
ip_defrag.sh in net from ubuntu_kernel_selftests failed with 5.0 / 5.3
/ 5.4 kernel
Status in ubuntu-kernel-tests:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Disco:

Bug description:
[Impact]
Failure to run ip_defrag deterministically.
[Fix]
Use smaller packets and ignore EPERM.
[Test case]
Run the test multiple times without observing failures.
[Regression potential]
If the test fix is incorrect, it will cause us to miss real kernel bugs. But
as it is now, we are already ignoring its results.
