/* SCTP kernel Implementation
* Copyright (c) 2003 Hewlett-Packard Development Company, L.P
* (C) Copyright IBM Corp. 2004
*
* This file has test cases to test the socket (), bind () and listen () for
* 1-1 style sockets
*
* socket () Tests:
* ---------------
* TEST1: Invalid domain
* TEST2: Invalid type
* TEST3: Opening a TCP style socket
*
* bind () Tests:
* -------------
* TEST4: Invalid address
* TEST5: Invalid address length
* TEST6: Invalid socket descriptor
* TEST7: Invalid host name
* TEST8: On a socket that is already bound
* TEST9: On reserved ports
* TEST10: INADDR_ANY address and non-zero port
* TEST11: INADDR_ANY address and zero port
* TEST12: Local address and zero port
*
* listen () Tests:
* ---------------
* TEST13: Bad socket descriptor
* TEST14: Invalid socket
* TEST15: Listening a bound socket
