libceph: support SERVER_JEWEL feature bits

2017-07-07T15:25:15+00:00

Only MON_STATEFUL_SUB, really. MON_ROUTE_OSDMAP and OSDSUBOP_NO_SNAPCONTEXT are irrelevant. Signed-off-by: Ilya Dryomov

libceph: drop version variable from ceph_monmap_decode()

2017-05-23T18:32:22+00:00

It's set but not used: CEPH_FEATURE_MONNAMES feature bit isn't advertised, which guarantees a v1 MonMap. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: no need for GFP_NOFS in ceph_monc_init()

2016-12-12T22:09:21+00:00

It's called during inital setup, when everything should be allocated with GFP_KERNEL. Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

libceph: support for blacklisting clients

2016-08-24T21:49:15+00:00

Reuse ceph_mon_generic_request infrastructure for sending monitor commands. In particular, add support for 'blacklist add' to prevent other, non-responsive clients from making further updates.

libceph: make cancel_generic_request() static

2016-08-08T19:41:42+00:00

Fixes the following sparse warning: net/ceph/mon_client.c:577:6: warning: symbol 'cancel_generic_request' was not declared. Should it be static? Signed-off-by: Wei Yongjun Signed-off-by: Ilya Dryomov

libceph: fsmap.user subscription support

libceph: replace ceph_monc_request_next_osdmap()

2016-05-25T23:15:30+00:00

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

libceph: async MON client generic requests

2016-05-25T23:15:29+00:00

For map check, we are going to need to send CEPH_MSG_MON_GET_VERSION messages asynchronously and get a callback on completion. Refactor MON client to allow firing off generic requests asynchronously and add an async variant of ceph_monc_get_version(). ceph_monc_do_statfs() is switched over and remains sync.

libceph: handle_one_map()

2016-05-25T23:12:27+00:00

Separate osdmap handling from decoding and iterating over a bag of maps in a fresh MOSDMap message. This sets up the scene for the updated OSD client. Of particular importance here is the addition of pi->was_full, which can be used to answer "did this pool go full -> not-full in this map?". This is the key bit for supporting pool quotas. We won't be able to downgrade map_sem for much longer, so drop downgrade_write(). Signed-off-by: Ilya Dryomov
