The definitions for the ceph_mds_session and ceph_osd both contain five fields related only to "authorizers." Encapsulate those fields into their own struct type, allowing for better isolation in some upcoming patches. Fix the #includes in "linux/ceph/osd_client.h" to lay out their more complete canonical path. Signed-off-by: NAlex Elder <elder@inktank.com> Reviewed-by: NSage Weil <sage@inktank.com>

ceph_osd_request struct allocates a 40-byte buffer for object names. RBD image names can be up to 96 chars long (100 with the .rbd suffix), which results in the object name for the image being truncated, and a subsequent map failure. Increase the oid buffer in request messages, in order to avoid the truncation. Signed-off-by: NStratos Psomadakis <psomas@grnet.gr> Signed-off-by: NSage Weil <sage@newdream.net>

The r_req_lru_item list node moves between several lists, and that cycle is not directly related (and does not begin) with __register_request(). Initialize it in the request constructor, not __register_request(). This fixes later badness (below) when OSDs restart underneath an rbd mount. Crashes we've seen due to this include: [ 213.974288] kernel BUG at net/ceph/messenger.c:2193! and [ 144.035274] BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 [ 144.035278] IP: [<ffffffffa036c053>] con_work+0x1463/0x2ce0 [libceph] Signed-off-by: NSage Weil <sage@newdream.net>

Keep track of when an outgoing message is ACKed (i.e., the server fully received it and, presumably, queued it for processing). Time out OSD requests only if it's been too long since they've been received. This prevents timeouts and connection thrashing when the OSDs are simply busy and are throttling the requests they read off the network.

Fix the request transition from linger -> normal request. The key is to preserve r_osd and requeue on the same OSD. Reregister as a normal request, add the request to the proper queues, then unregister the linger. Fix the unregister helper to avoid clearing r_osd (and also simplify the parallel check in __unregister_request()).

We should only clear r_osd if we are neither registered as a linger or a regular request. We may unregister as a linger while still registered as a regular request (e.g., in reset_osd). Incorrectly clearing r_osd there leads to a null pointer dereference in __send_request. Also simplify the parallel check in __unregister_request() where we just removed r_osd_item and know it's empty. Signed-off-by: NSage Weil <sage@newdream.net>

Lingering requests are requests that are sent to the OSD normally but tracked also after we get a successful request. This keeps the OSD connection open and resends the original request if the object moves to another OSD. The OSD can then send notification messages back to us if another client initiates a notify. This framework will be used by RBD so that the client gets notification when a snapshot is created by another node or tool.

If we send a request to osd A, and the request's pg remaps to osd B and then back to A in quick succession, we need to resend the request to A. The old code was only calling kick_requests after processing all incremental maps in a message, so it was very possible to not resend a request that needed to be resent. This would make the osd eventually time out (at least with the current default of osd timeouts enabled). The correct approach is to scan requests on every map incremental. This patch refactors the kick code in a few ways: - all requests are either on req_lru (in flight), req_unsent (ready to send), or req_notarget (currently map to no up osd) - mapping always done by map_request (previous map_osds) - if the mapping changes, we requeue. requests are resent only after all map incrementals are processed. - some osd reset code is moved out of kick_requests into a separate function - the "kick this osd" functionality is moved to kick_osd_requests, as it is unrelated to scanning for request->pg->osd mapping changes Signed-off-by: NSage Weil <sage@newdream.net>

The alignment used for reading data into or out of pages used to be taken from the data_off field in the message header. This only worked as long as the page alignment matched the object offset, breaking direct io to non-page aligned offsets. Instead, explicitly specify the page alignment next to the page vector in the ceph_msg struct, and use that instead of the message header (which probably shouldn't be trusted). The alloc_msg callback is responsible for filling in this field properly when it sets up the page vector. Signed-off-by: NSage Weil <sage@newdream.net>

We used to infer alignment of IOs within a page based on the file offset, which assumed they matched. This broke with direct IO that was not aligned to pages (e.g., 512-byte aligned IO). We were also trusting the alignment specified in the OSD reply, which could have been adjusted by the server. Explicitly specify the page alignment when setting up OSD IO requests.

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: NSage Weil <sage@newdream.net>
