The entry point from userspace is net/socket.c . The functions which are called is those from "struct proto_ops". Both "struct sock" and "struct proto" look pretty weird to me too. It seems that they are meant to be tools which make implementing protocols easier, but they are sometimes required by upper layers. Take a look at e.g. sock_getsockopt(). -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
