This series of patches resolves several SCTP association hangs observed during
SCTP stress testing.  Observable symptoms include communications hangs with
data being held in the association reassembly and/or lobby (ordering) queues.
Close examination of reassembly/ordering queues may show either duplicated
or missing packets.

Just nitpicking here ... all of your 4 patches have the same first paragraph,
which can actually be left out completely if it is already in your patch cover
letter stated.

   sctp: fix association hangs due to off-by-one errors in
     sctp_tsnmap_grow()
   sctp: fix association hangs due to reneging packets below the
     cumulative TSN ACK point
   sctp: fix association hangs due to errors when reneging events from
     the ordering queue
   sctp: fix association hangs due to partial delivery errors
