2010-10-20ceph: factor out libceph from Ceph file systemYehuda Sadeh
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>
2010-08-10ceph: generalize mon requests, add pool op supportYehuda Sadeh
Generalize the current statfs synchronous requests, and support pool_ops. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-21ceph: reuse mon subscribe message instead of allocated anewSage Weil
Use the same message, allocated during startup. No need to reallocate a new one each time around (and potentially ENOMEM). Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: make mon client statfs handling more genericYehuda Sadeh
This is being done so that we could reuse the statfs infrastructure with other requests that return values. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: drop unnecessary msgpool for mon_client subscribe_ackSage Weil
Preallocate a single message to reuse instead. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: drop unnecessary msgpool for mon_client auth_replySage Weil
Preallocate a single reply message that we can reuse instead. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: clean up statfsSage Weil
Avoid unnecessary msgpool. Preallocate reply. Fix use-after-free race. Signed-off-by: Sage Weil <sage@newdream.net>
2010-02-16ceph: use rbtree for mon statfs requestsSage Weil
An rbtree is lighter weight, particularly given we will generally have very few in-flight statfs requests. Signed-off-by: Sage Weil <sage@newdream.net>
2010-02-10ceph: allow renewal of auth credentialsSage Weil
Add infrastructure to allow the mon_client to periodically renew its auth credentials. Also add a messenger callback that will force such a renewal if a peer rejects our authenticator. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
2009-11-18ceph: negotiate authentication protocol; implement AUTH_NONE protocolSage Weil
When we open a monitor session, we send an initial AUTH message listing the auth protocols we support, our entity name, and (possibly) a previously assigned global_id. The monitor chooses a protocol and responds with an initial message. Initially implement AUTH_NONE, a dummy protocol that provides no security, but works within the new framework. It generates 'authorizers' that are used when connecting to (mds, osd) services that simply state our entity name and global_id. This is a wire protocol change.

2009-10-06ceph: monitor clientSage Weil
The monitor cluster is responsible for managing cluster membership and state. The monitor client handles what minimal interaction the Ceph client has with it: checking for updated versions of the MDS and OSD maps, getting statfs() information, and unmounting.
