From de4594a51c904ddcd6c3a6cdd100f7c1d94d3239 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Tue, 20 Nov 2012 10:14:30 +0000 Subject: sctp: send abort chunk when max_retrans exceeded In the event that an association exceeds its max_retrans attempts, we should send an ABORT chunk indicating that we are closing the assocation as a result. Because of the nature of the error, its unlikely to be received, but its a nice clean way to close the association if it does make it through, and it will give anyone watching via tcpdump a clue as to what happened.
