Hi, I noticed that the TCP code (linux 2.2.14) locks the socket (using lock_sock()) before doing a send (tcp_do_sendmsg), and during a receive (tcp_recvmsg). Besides that, I have seen lock_sock() being called at a number of other places in the TCP code. Could someone please explain to me the working of lock_sock(), and in what cases it should be called? The reason I am looking at lock_sock is because I have a project in which I create 2 INET sockets (say s1 and s2), and each socket can receive data, that it sends down through the other. For ex: s1 receives some data, processes it, and sends it through s2, and vice versa. I think I have to lock the socket that I am sending data down on, but am not too sure if I have to lock the receiving socket as well. Any help or tips would be very much appreciated. Thanks, Mahesh. __________________________________________________ Do You Yahoo!? Kick off your party with Yahoo!
