From 519d25679e8ae7433c758b9e74b19144f61b90f8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 16 Jun 2009 21:36:44 +0100 Subject: [PATCH] RxRPC: Don't attempt to reuse aborted connections Connections that have seen a connection-level abort should not be reused as the far end will just abort them again; instead a new connection should be made. Connection-level aborts occur due to such things as authentication failures.
