Look at how DCCP and TCP share code, using abstractions such as: struct inet_connection_sock struct inet_request_sock struct inet_timewait_sock struct inet_hashinfo I suggest too that you read my OLS 2004 paper: http://www.linuxsymposium.org/2005/linuxsymposium_procv1.pdf Page 305: "3 Writing a New Protocol for the Linux Kernel" and page 307: "6 Linux Infrastructure for Internet Transport Protocols", but I'm a lazy boy and haven't properly finished this paper, it stops at processing connection requests, also at that time I'm not sure if I had finished the work on struct inet_hashinfo, generalising the hashtables operations for socket ID lookup, etc, look at dccp_v4_rcv and dccp_v6_rcv and you should get the idea. Also I'm more than interested in discussing ideas for further generalisation of the Linux networking infrastructure :-) - Arnaldo - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
