* libceph: Create a new key type "ceph".Tommi Virtanen2011-03-291-0/+62
| | | | | | | | This allows us to use existence of the key type as a feature test, from userspace. Signed-off-by: Tommi Virtanen <tommi.virtanen@dreamhost.com> Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: Move secret key parsing earlier.Tommi Virtanen2011-03-291-0/+11
| | | | | | | | | This makes the base64 logic be contained in mount option parsing, and prepares us for replacing the homebew key management with the kernel key retention service. Signed-off-by: Tommi Virtanen <tommi.virtanen@dreamhost.com> Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: factor out libceph from Ceph file systemYehuda Sadeh2010-10-211-0/+412
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>
