From 3ec50d1868a9e0493046400bb1fdd054c7f64ebd Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 23 May 2012 14:35:23 -0500 Subject: [PATCH] libceph: clear NEGOTIATING when done A connection state's NEGOTIATING bit gets set while in CONNECTING state after we have successfully exchanged a ceph banner and IP addresses with the connection's peer (the server). But that bit is not cleared again--at least not until another connection attempt is initiated. Instead, clear it as soon as the connection is fully established. Also, clear it when a socket connection gets prematurely closed in the midst of establishing a ceph connection (in case we had reached the point where it was set).
