I am working on this test case. ip_defrag.sh fails with non-overlapping
as well, but only sometimes. I managed to find out the cause, and sent a
fix upstream, but this is under discussion now on how to fix it.
The EPERM failure with overlap happens more often, you just need to run
the test multiple times to see it fail once in a while. I just remove
the other tests from ip_defrag.sh and run ip_defrag.sh in a loop until
it fails. That still needs some investigation, but I believe this is no
regression on the kernels at all.
