Hi David, Now that 2.6.10 is out, please take a look if this is acceptable, the following patches will deal with udp_sock, tcp_sock, etc. This is the start of the series of patches that will introduce struct connection_sock, reducing the memory used by non connected protocols, such as UDP. It is available at: bk://kernel.bkbits.net/acme/connection_sock-2.6 Best Regards, - Arnaldo
