libceph: advertise support for NEW_OSDOP_ENCODING and SERVER_LUMINOUS

2017-07-07T15:26:24+00:00

All four SERVER_LUMINOUS feature bits are implemented, switch it on! NEW_OSDOP_ENCODING doesn't mean much for the client (it signifies support for MOSDOp v6) but needs to be enabled in order to get the latest (currently v25) pg_pool_t. Signed-off-by: Ilya Dryomov Acked-by: Sage Weil

libceph: osd_state is 32 bits wide in luminous

libceph: pg_upmap[_items] infrastructure

2017-07-07T15:25:18+00:00

pg_temp and pg_upmap encodings are the same (PG -> array of osds), except for the incremental remove: it's an empty mapping in new_pg_temp for pg_temp and a separate old_pg_upmap set for pg_upmap. (This isn't to allow for empty pg_upmap mappings -- apparently, pg_temp just wasn't looked at as an example for pg_upmap encoding.) Reuse __decode_pg_temp() for decoding pg_upmap and new_pg_upmap. __decode_pg_temp() stores into pg_temp union member, but since pg_upmap union member is identical, reading through pg_upmap later is OK.

libceph: ceph_decode_skip_* helpers

2017-07-07T15:25:18+00:00

Some of these won't be as efficient as they could be (e.g. ceph_decode_skip_set(... 32 ...) could advance by len * sizeof(u32) once instead of advancing by sizeof(u32) len times), but that's fine and not worth a bunch of extra macro code. Replace skip_name_map() with ceph_decode_skip_map as an example. Signed-off-by: Ilya Dryomov

libceph: make DEFINE_RB_* helpers more general

2017-07-07T15:25:17+00:00

Initially for ceph_pg_mapping, ceph_spg_mapping and ceph_hobject_id, compared with ceph_pg_compare(), ceph_spg_compare() and hoid_compare() respectively. Signed-off-by: Ilya Dryomov

libceph: make sure need_resend targets reflect latest map

2017-07-07T15:25:16+00:00

Otherwise we may miss events like PG splits, pool deletions, etc when we get multiple incremental maps at once. Because check_pool_dne() can now be fed an unlinked request, finish_request() needed to be taught to handle unlinked requests. Signed-off-by: Ilya Dryomov

libceph: resend on PG splits if OSD has RESEND_ON_SPLIT

2017-07-07T15:25:16+00:00

Note that ceph_osd_request_target fields are updated regardless of RESEND_ON_SPLIT. Signed-off-by: Ilya Dryomov
