From 9bdfa78b9c4ac354bc358e2d3bd6e9bc1df7d354 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Mon, 5 Oct 2015 08:32:51 -0600 Subject: [PATCH] net: Fix vti use case with oif in dst lookups for IPv6 It occurred to me yesterday that a92a1e0451710 ("net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set") means that xfrm6_dst_lookup needs the FLOWI_FLAG_SKIP_NH_OIF flag set. This latest commit causes the oif to be considered in lookups which is known to break vti. This explains why 91c754603a34 did not the IPv6 change at the time it was submitted.
