1 /* SCTP kernel Implementation
2 * Copyright (c) 2003 Hewlett-Packard Development Company, L.P
3 * (C) Copyright IBM Corp. 2004
4 *
5 * This file has test cases to test the sctp_connectx () call for 1-1 style sockets
6 *
7 * TEST1: Bad socket descriptor
8 * TEST2: Invalid socket
9 * TEST3: Invalid address
10 * TEST4: Invalid address length
11 * TEST5: Invalid address family
12 * TEST6: Valid blocking sctp_connectx
13 * TEST7: Connect when accept queue is full
14 * TEST8: On a listening socket
15 * TEST9: On established socket
16 * TEST10: Connect to re-establish a closed association.
