Modified files: sys/netinet : ip_carp.c Log message: Use a workaround for detached parent in carp_proto_input_c(). A NULL dereference can happen since processing protocol layer is deffered to a second task. In other words the NET_LOCK() is released then regrabbed between ip_input() and carp_proto_input(). The same workaround is already in use in carp_output() due to deffered processing in case of IPsec. The real fix is to make carp(4) MP-safe and use if_get(9) there, any taker? Found & fix tested by Hrvoje Popovski.
