linux-stable.git/net/ceph/mon_client.c, branch linux-3.2.y Linux kernel stable tree libceph: gracefully handle large reply messages from the mon 2014-11-05T20:27:42+00:00 Sage Weil sage@redhat.com 2014-08-04T14:01:54+00:00 df0fddbf7ec235d49847efcda0d3c901d7964ba5 commit 73c3d4812b4c755efeca0140f606f83772a39ce4 upstream. We preallocate a few of the message types we get back from the mon. If we get a larger message than we are expecting, fall back to trying to allocate a new one instead of blindly using the one we have.

ceph: factor out libceph from Ceph file system 2010-10-20T22:37:28+00:00 Yehuda Sadeh yehuda@hq.newdream.net 2010-04-06T22:14:15+00:00 3d14c5d2b6e15c21d8e5467dc62d33127c23a644 This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
