Subject: OOPS in nf_getsockopt

Hi,

With kernel 5.0 and 5.1-rc4, we encounter OOPS in nf_getsockopt on aarch64 (on Raspberry Pi3 and qemu).
This can be triggered with podman or iptables/ip6tables.
The easiest way to reproduce is with 'iptables -F output' and it will trigger this bug about 50% of the times.

It seems to be similar to https://www.spinics.net/lists/netdev/msg520391.html

This bug has been reported here: https://bugzilla.suse.com/show_bug.cgi?id=1131864
And the decoded trace is available here: https://bugzilla.suse.com/attachment.cgi?id=802527

Thanks,
Guillaume
