Date: Sun, 7 Oct 2012 14:26:04 +0300 From: Julian Anastasov <ja@....bg> To: netdev@...r.kernel.org Subject: [PATCH net 2/6] ipv4: fix forwarding for strict source routes After the change "Adjust semantics of rt->rt_gateway" (commit f8126f1d51) rt_gateway can be 0 but ip_forward() compares it directly with nexthop. What we want here is to check if traffic is to directly connected nexthop and to fail if using gateway.
