Subject: [PATCH v3 0/4] sctp: fix association hangs due to reassembly/ordering logic

From: "Lee A. Roberts" <lee.roberts@...com>

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.

In version #2, corrected build failure in initial version of patch series
due to wrong calling sequence for sctp_ulpq_partial_delivery() being inserted
in sctp_ulpq_renege().

In version #3, adjusted patch documentation to be less repetitive.

Lee A. Roberts (4):
  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
