Subject: [PATCH net 0/2] net: convert ipv6_stub to ip6_dst_lookup_flow

Xiumei Mu reported a bug in a VXLAN over IPsec setup:

  IPv6 | ESP | VXLAN

Using this setup, packets go out unencrypted, because VXLAN over IPv6
gets its route from ipv6_stub->ipv6_dst_lookup (in vxlan6_get_route),
which doesn't perform an XFRM lookup.

This patchset first makes ip6_dst_lookup_flow suitable for some
existing users of ipv6_stub->ipv6_dst_lookup by adding a 'net'
argument, then converts all those users.

Sabrina Dubroca (2):
  net: ipv6: add net argument to ip6_dst_lookup_flow
  net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookup
