Hello David Howells,

The patch 75b54cb57ca3: "rxrpc: Add IPv6 support" from Sep 13, 2016,
leads to the following static checker warning:

	net/rxrpc/peer_object.c:196 rxrpc_assess_MTU_size()
	warn: 'dst' isn't an ERR_PTR

net/rxrpc/peer_object.c
   193                  fl6->fl6_dport = htons(7001);
   194                  fl6->fl6_sport = htons(7000);
   195                  dst = ip6_route_output(&init_net, NULL, fl6);
   196                  if (IS_ERR(dst)) {
                            ^^^^^^^^^^^
Maybe you want to check dst->error?

   197                          _leave(" [route err %ld]", PTR_ERR(dst));
   198                          return;
   199                  }
   200                  break;

regards,
