OK, lets try to provide a cumulative patch with a good Changelog ? And please try a "allyesconfig" build, because it doesnt build right now : CC [M] net/decnet/dn_neigh.o net/decnet/dn_route.c: In function 'dn_forward': net/decnet/dn_route.c:757:31: error: 'struct dst_entry' has no member named 'neighbour' make[2]: *** [net/decnet/dn_route.o] Error 1 make[2]: *** Waiting for unfinished jobs.... net/decnet/dn_neigh.c: In function 'dn_long_output': net/decnet/dn_neigh.c:230:31: error: 'struct dst_entry' has no member named 'neighbour' net/decnet/dn_neigh.c: In function 'dn_short_output': net/decnet/dn_neigh.c:277:31: error: 'struct dst_entry' has no member named 'neighbour' net/decnet/dn_neigh.c: In function 'dn_phase3_output': net/decnet/dn_neigh.c:321:31: error: 'struct dst_entry' has no member named 'neighbour' make[2]: *** [net/decnet/dn_neigh.o] Error 1 make[1]: *** [net/decnet] Error 2 So there is at least one patch missing ? Once you believe its ok, please send a proper patch with changelog like this : [PATCH] net: hot fix for stable kernels This cumulative patch fixes IP redirect NULL dereferences added in commit f39925dbde77 (ipv4: Cache learned redirect information in inetpeer.)
