From bec9640bb0d451813b1bb1f2cc13a5bfb17c3e48 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Thu, 30 Jul 2009 18:08:28 -0400 Subject: sctp: Disallow new connection on a closing socket If a socket has a lot of association that are in the process of of being closed/aborted, it is possible for a remote to establish new associations during the time period that the old ones are shutting down. If this was a result of a close() call, there will be no socket and will cause a memory leak. We'll prevent this by setting the socket state to CLOSING and disallow new associations when in this state.
