This is a note to let you know that I have just added a patch titled libceph: clear NEGOTIATING when done to the linux-3.5.y-queue branch of the 3.5.yuz extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.yuz tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From 99b3f60a8bbbada2597dd983a068635042b28b4f Mon Sep 17 00:00:00 2001 From: Alex Elder <elder@inktank.com> Date: Wed, 23 May 2012 14:35:23 -0500 Subject: [PATCH 37/78] libceph: clear NEGOTIATING when done commit 3ec50d1868a9e0493046400bb1fdd054c7f64ebd upstream. 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).
