sctp: Fix oops when INIT-ACK indicates that peer doesn't support AUTH
If INIT-ACK is received with SupportedExtensions parameter which indicates that the peer does not support AUTH, the packet will be silently ignore, and sctp_process_init() do cleanup all of the transports in the association. When T1-Init timer is expires, OOPS happen while we try to choose a different init transport. The solution is to only clean up the non-active transports, i.e the ones that the peer added. However, that introduces a problem with sctp_connectx(), because we don't mark the proper state for the transports provided by the user. So, we'll simply mark user-provided transports as ACTIVE. That will allow INIT retransmissions to work properly in the sctp_connectx() context and prevent the crash. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.
