Subject: [PATCH nf 0/2] route_me_harder routing loop with tunnels

Hi Pablo,

This series fixes a bug in the route_me_harder family of functions with
regards to tunnel interfaces. The first patch contains an addition to
the wireguard test suite; I normally send my wireguard patches through
Dave's tree, but I thought it'd be nice to send these together here
because the test case is illustrative of the issue. The second patch
then fixes the issue with a lengthy explanation of what's going on.

These are intended for net.git/nf.git, not the -next variety, and to
eventually be backported to stable. So, the second patch has a proper
Fixes: line on it to help with that.

Thanks,
Jason

  wireguard: selftests: check that route_me_harder packets use the right
    sk
  netfilter: use actual socket sk rather than skb sk when routing harder
