Subject: [PATCH] RDS: verify the underlying transport exists before creating a connection
Date: Fri, 4 Sep 2015 12:43:39 -0400 [thread overview]
Message-ID: <1441385019-27019-1-git-send-email-sasha.levin@oracle.com> (raw)
There was no verification that an underlying transport exists when creating
a connection, this would cause dereferencing a NULL ptr.
