* ceph: reuse mon subscribe message instead of allocated anewSage Weil2010-05-211-1/+1
| | | | | | | 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>
* ceph: make mon client statfs handling more genericYehuda Sadeh2010-05-171-7/+8
| | | | | | | | 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>
* ceph: drop unnecessary msgpool for mon_client subscribe_ackSage Weil2010-05-171-5/+1
| | | | | | Preallocate a single message to reuse instead. Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: drop unnecessary msgpool for mon_client auth_replySage Weil2010-05-171-3/+2
| | | | | | Preallocate a single reply message that we can reuse instead. Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: clean up statfsSage Weil2010-05-171-2/+3
| | | | | | Avoid unnecessary msgpool. Preallocate reply. Fix use-after-free race. Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: use rbtree for mon statfs requestsSage Weil2010-02-161-2/+3
| | | | | | | 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>
* ceph: allow renewal of auth credentialsSage Weil2010-02-101-0/+3
| | | | | | | | | 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>
* ceph: negotiate authentication protocol; implement AUTH_NONE protocolSage Weil2009-11-181-5/+9
| | | | | | | | | | | | | | | | 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.

* ceph: monitor clientSage Weil2009-10-061-0/+109
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.
