ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28+00:00

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

ceph-rbd: osdc support for osd call and rollback operations

2010-10-20T22:37:25+00:00

This will be used for rbd snapshots administration. Signed-off-by: Yehuda Sadeh

ceph: messenger and osdc changes for rbd

2010-10-20T22:37:18+00:00

Allow the messenger to send/receive data in a bio. This is added so that we wouldn't need to copy the data into pages or some other buffer when doing IO for an rbd block device. We can now have trailing variable sized data for osd ops. Also osd ops encoding is more modular. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: refactor osdc requests creation functions

2010-10-20T22:36:01+00:00

The osd requests creation are being decoupled from the vino parameter, allowing clients using the osd to use other arbitrary object names that are not necessarily vino based. Also, calc_raw_layout now takes a snap id. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: avoid null deref in osd request error path

2010-10-07T15:00:23+00:00

If we interrupt an osd request, we call __cancel_request, but it wasn't verifying that req->r_osd was non-NULL before dereferencing it. This could cause a crash if osds were flapping and we aborted a request on said osd. Reported-by: Henry C Chang Signed-off-by: Sage Weil

ceph: fix osd request lru adjustment when sending request

2010-08-23T04:34:27+00:00

Fix argument order. We want to move the item to the end of the list, not change the position of the head. Signed-off-by: Henry C Chang Signed-off-by: Sage Weil

ceph: whitespace cleanup

ceph: only set num_pages in calc_layout

2010-08-02T03:11:40+00:00

Setting it elsewhere is unnecessary and more fragile. Signed-off-by: Sage Weil

ceph: use complete_all and wake_up_all

2010-07-27T20:11:17+00:00

This fixes an issue triggered by running concurrent syncs. One of the syncs would go through while the other would just hang indefinitely. In any case, we never actually want to wake a single waiter, so the *_all functions should be used. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: fix map handler error path

2010-06-13T17:34:36+00:00

Don't leak message if we receive an unexpected message type. Signed-off-by: Sage Weil
