2013-05-02libceph: wrap auth methods in a mutexSage Weil1-22/+56
The auth code is called from a variety of contexts, include the mon_client (protected by the monc's mutex) and the messenger callbacks (currently protected by nothing). Avoid chaos by protecting all auth state with a mutex. Nothing is blocking, so this should be simple and lightweight.

2013-05-02libceph: wrap auth ops in wrapper functionsSage Weil1-0/+47
Use wrapper functions that check whether the auth op exists so that callers do not need a bunch of conditional checks. Simplifies the external interface. Signed-off-by: Sage Weil <sage@inktank.com> Reviewed-by: Alex Elder <elder@inktank.com>
2011-03-29ceph: Move secret key parsing earlier.Tommi Virtanen1-4/+4
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>
2010-10-21ceph: factor out libceph from Ceph file systemYehuda Sadeh1-0/+259
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>
