Kernel panic on x86_64 machine running mainline 4.17.0 kernel while testing
selftests bpf test_tunnel.sh test caused this kernel panic.
I have noticed this kernel panic start happening from
4.17.0-rc7-next-20180529 and still happening on 4.17.0-next-20180608.

This looks like a bug that I've seen already. If it is what I think,
then commit 2c205dd3981f ("netfilter: add struct nf_nat_hook and use
it") introduced this bug.
There was already a fix for this on the netdev list, but
I don't know the current status of that patch:

Hi, I applied the patch and ran bpf/test_tunnel.sh and I I couldn't
see any crash.
However, the script never returned (I had to Ctrl+c to get back), any ideas ?
See log from the test below.
Cheers,
Anders

Yes it should but it didn't.
However, when I reran the test_tunnel.sh today with kernel next-20180613
I got back from from the script and the test passed "PASS: xfrm tunnel".
So I'm not sure what happened before. =/

Great.

Kernel panic on x86_64 machine running mainline kernel while testing
selftests bpf tests caused this kernel crash.
I have noticed same kernel crash on 4.17.0-next-20180608 on
qemu_x86_64 while running selftests intel_pstate.
