Subject: [PATCH net] vrf: Fix IPv6 with qdisc and xfrm
Date: Tue, 21 Apr 2020 17:48:27 -0600 [thread overview]
Message-ID: <20200421234827.63465-1-dsahern@kernel.org> (raw)
From: David Ahern <dsahern@gmail•com>
When a qdisc is attached to the VRF device, the packet goes down the ndo
xmit function which is setup to send the packet back to the VRF driver
which does a lookup to send the packet out. The lookup in the VRF driver
is not considering xfrm policies. Change it to use ip6_dst_lookup_flow
rather than ip6_route_output.
Fixes: 35402e313663 ("net: Add IPv6 support to VRF device")
