Subject: [PATCH net 0/2] Netfilter fixes for net (v2)

This is a v2 including a extended PR with one more fix.

-o-

Hi,

This patchset contains Netfilter fixes for net:

1) syzkaller managed to triger UaF due to missing reference on netns in
   bpf infrastructure, from Florian Westphal.

2) Fix incorrect conversion from NFPROTO_UNSPEC to NFPROTO_{IPV4,IPV6}
   in the following xtables targets: MARK and NFLOG. Moreover, add
   missing

I have my half share in this mistake, I did not take the necessary time
to review this: For several years I have been struggling to keep working
on Netfilter, juggling a myriad of side consulting projects to stop
burning my own savings.

I have extended the iptables-tests.py test infrastructure to improve the
coverage of ip6tables and detect similar problems in the future.

Please, pull these changes from:
