libceph: initialize last_linger_id with a large integer

2016-11-10T19:13:08Z

osdc->last_linger_id is a counter for lreq->linger_id, which is used for watch cookies. Starting with a large integer should ease the task of telling apart kernel and userspace clients. Signed-off-by: Ilya Dryomov

libceph: add ceph_osdc_call() single-page helper

2016-08-24T21:49:15Z

Add a convenience function to osd_client to send Ceph OSD 'class' ops. The interface assumes that the request and reply data each consist of single pages. Signed-off-by: Douglas Fuller Signed-off-by: Ilya Dryomov Reviewed-by: Mike Christie Reviewed-by: Alex Elder

libceph: support for CEPH_OSD_OP_LIST_WATCHERS

2016-08-24T21:49:15Z

Add support for this Ceph OSD op, needed to support the RBD exclusive lock feature. Signed-off-by: Douglas Fuller [idryomov@gmail.com: refactor, misc fixes throughout] Signed-off-by: Ilya Dryomov Reviewed-by: Mike Christie Reviewed-by: Alex Elder

libceph: fix some missing includes

2016-07-28T00:55:35Z

- decode.h needs slab.h for kmalloc() - osd_client.h needs msgpool.h for struct ceph_msgpool - msgpool.h doesn't need messenger.h Signed-off-by: Ilya Dryomov

libceph: change ceph_osdmap_flag() to take osdc

2016-05-30T21:00:22Z

For the benefit of every single caller, take osdc instead of map. Also, now that osdc->osdmap can't ever be NULL, drop the check. Signed-off-by: Ilya Dryomov

libceph: replace ceph_monc_request_next_osdmap()

2016-05-25T23:15:30Z

... with a wrapper around maybe_request_map() - no need for two osdmap-specific functions. Signed-off-by: Ilya Dryomov

libceph: pool deletion detection

2016-05-25T23:15:29Z

This adds the "map check" infrastructure for sending osdmap version checks on CALC_TARGET_POOL_DNE and completing in-flight requests with -ENOENT if the target pool doesn't exist or has just been deleted. Signed-off-by: Ilya Dryomov

libceph: support for checking on status of watch

2016-05-25T23:15:28Z

Implement ceph_osdc_watch_check() to be able to check on status of watch. Note that the time it takes for a watch/notify event to get delivered through the notify_wq is taken into account. Signed-off-by: Ilya Dryomov

libceph: support for sending notifies

2016-05-25T23:15:28Z

Implement ceph_osdc_notify() for sending notifies. Due to the fact that the current messenger can't do read-in into pagelists (it can only do write-out from them), I had to go with a page vector for a NOTIFY_COMPLETE payload, for now. Signed-off-by: Ilya Dryomov

libceph, rbd: ceph_osd_linger_request, watch/notify v2

2016-05-25T23:15:02Z

This adds support and switches rbd to a new, more reliable version of watch/notify protocol. As with the OSD client update, this is mostly about getting the right structures linked into the right places so that reconnects are properly sent when needed. watch/notify v2 also requires sending regular pings to the OSDs - send_linger_ping(). A major change from the old watch/notify implementation is the introduction of ceph_osd_linger_request - linger requests no longer piggy back on ceph_osd_request. ceph_osd_event has been merged into ceph_osd_linger_request. All the details are now hidden within libceph, the interface consists of a simple pair of watch/unwatch functions and ceph_osdc_notify_ack(). ceph_osdc_watch() does return ceph_osd_linger_request, but only to keep the lifetime management simple. ceph_osdc_notify_ack() accepts an optional data payload, which is relayed back to the notifier. Portions of this patch are loosely based on work by Douglas Fuller and Mike Christie . Signed-off-by: Ilya Dryomov
