Yes, this is possible, check the ccid3 packet history allocator, it doesn't accounts the packet to the socket, try adding some basic upper bound on the number of packets on a variable in the dccp_sock struct, doing it in a similar way as TCP (memory moderation, etc) is in the todo list. - Arnaldo - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
