Date: Mon, 3 Aug 2015 17:39:21 +0100 From: Robert Shearman <rshearma@...cade.com> To: <davem@...emloft.net> CC: <netdev@...r.kernel.org>, Nicolas Dichtel <nicolas.dichtel@...nd.com>, Thomas Graf <tgraf@...g.ch>, Roopa Prabhu <roopa@...ulusnetworks.com>, "Robert Shearman" <rshearma@...cade.com> Subject: [PATCH net-next 2/2] ipv4: apply lwtunnel encap for locally-generated packets lwtunnel encap is applied for forwarded packets, but not for locally-generated packets. This is because the output function is not overridden in __mkroute_output, unlike it is in __mkroute_input. The lwtunnel state is correctly set on the rth through the call to rt_set_nexthop, so all that needs to be done is to override the dst output function to be lwtunnel_output if there is lwtunnel state present and it requires output redirection.
