I've installed lksctp-tools-1.0.15 on a CentOS 6.4 system with the following kernel: Linux version 2.6.32-358.6.1.el6.x86_64 (mockbuild@xxxxxxxxxxxxxxxxxxxxxxxx) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Tue Apr 23 19:29:00 UTC 2013 When I attempt to build/run the v4test, I get failures in test_sockopt, test_tcp_style, test_1_to_1_send, and test_1_to_1_sendmsg. Also, a "successful" run of the test suite results in the kernel logging these messages: Nov 6 05:49:16 kernel: SCTP: Use of int in maxseg socket option deprecated Nov 6 05:49:16 kernel: SCTP: Use struct sctp_assoc_value instead All the failing tests report "BROK : bind: Address already in use". With test_sockopt, it is at step 5. It appears that it is trying to set up a new set of client/server sockets immediately after closing the sockets from the previous test, but using the same IP/port. Is the correct change more likely to be adding SO_REUSEADDR, or moving each test to its own set of ports?
