Suppose we have an SCTP connection with two paths. After connection is established, path1 is not available, thus this path is marked as inactive. Then traffic goes through path2, but for some reasons packets are delayed (after rto.max). Because packets are delayed, the retransmit mechanism will switch again to path1. At this time, we receive a delayed SACK from path2. When we update the state of the path in sctp_check_transmitted(), we do not take into account the source address of the SACK, hence we update the wrong path. Signed-off-by: Nicolas Dichtel <redacted>
Applied.
