Marcelo Ricardo Leitner 582eea2305 sctp: fix possibly using a bad saddr with a given dst ... Under certain circumstances, depending on the order of addresses on the interfaces, it could be that sctp_v[46]_get_dst() would return a dst with a mismatched struct flowi. For example, if when walking through the bind addresses and the first one is not a match, it saves the dst as a fallback (added in 410f03831c), but not the flowi. Then if the next one is also not a match, the previous dst will be returned but with the flowi information for the 2nd address, which is wrong. The fix is to use a locally stored flowi that can be used for such attempts, and copy it to the parameter only in case it is a possible match, together with the corresponding dst entry. The patch updates IPv6 code mostly just to be in sync. Even though the issue is also present there, it fallback is not expected to work with IPv6.
