[PATCH net v4 0/2] sctp: handle wrapped and duplicate RECONF responses

From: Jun Yang <[email protected]>

Fix response sequence zero lookup first, then make RECONF response
handling idempotent with an outstanding-request bitmask.

Jun Yang (2):
  sctp: distinguish sequence zero from wildcard in reconf lookup
  sctp: fix stream->outcnt underflow on duplicate RECONF responses
