====================
sctp: Fix problems with peer restart when in SHUTDOWN-PENDING state and socket is closed
These patches are related to the scenario described in commit
bdf6fa52f01b ("sctp: handle association restarts when the socket is
closed."). To recap, when our association is in SHUTDOWN-PENDING state
and we've closed our one-to-one socket, while the peer crashes without
being detected, restarts and reconnects using the same addresses and
ports, we start association shutdown.
In this case, Cumulative TSN Ack in the SHUTDOWN that we send has
always been incorrect. Additionally, bundling of the SHUTDOWN with the
COOKIE-ACK was broken by a later commit. This series fixes both of
these issues.
