ceph: fix bogus endianness change in ceph_ioctl_set_layout

2017-10-21T15:21:37Z

[ Upstream commit 24c149ad6914d349d8b64749f20f3f8ea5031fe0 ] sparse says: fs/ceph/ioctl.c:100:28: warning: cast to restricted __le64 preferred_osd is a __s64 so we don't need to do any conversion. Also, just remove the cast in ceph_ioctl_get_layout as it's not needed.

ceph: reduce i_nr_by_mode array size

2016-07-28T00:55:39Z

Track usage count for individual fmode bit. This can reduce the array size by half. Signed-off-by: Yan, Zheng

ceph: rados pool namespace support

2016-07-28T00:55:38Z

This patch adds codes that decode pool namespace information in cap message and request reply. Pool namespace is saved in i_layout, it will be passed to libceph when doing read/write. Signed-off-by: Yan, Zheng

libceph: define new ceph_file_layout structure

2016-07-28T00:55:36Z

Define new ceph_file_layout structure and rename old ceph_file_layout to ceph_file_layout_legacy. This is preparation for adding namespace to ceph_file_layout structure. Signed-off-by: Yan, Zheng

libceph: add an ONSTACK initializer for oids

2016-07-28T00:55:35Z

An on-stack oid in ceph_ioctl_get_dataloc() is not initialized, resulting in a WARN and a NULL pointer dereference later on. We will have more of these on-stack in the future, so fix it with a convenience macro. Fixes: d30291b985d1 ("libceph: variable-sized ceph_object_id") Signed-off-by: Ilya Dryomov

libceph: a major OSD client update

2016-05-25T23:14:03Z

This is a major sync up, up to ~Jewel. The highlights are: - per-session request trees (vs a global per-client tree) - per-session locking (vs a global per-client rwlock) - homeless OSD session - no ad-hoc global per-client lists - support for pool quotas - foundation for watch/notify v2 support - foundation for map check (pool deletion detection) support The switchover is incomplete: lingering requests can be setup and teared down but aren't ever reestablished. This functionality is restored with the introduction of the new lingering infrastructure (ceph_osd_linger_request, linger_work, etc) in a later commit. Signed-off-by: Ilya Dryomov

libceph: rename ceph_calc_pg_primary()

2016-05-25T22:36:25Z

Rename ceph_calc_pg_primary() to ceph_pg_to_acting_primary() to emphasise that it returns acting primary. Signed-off-by: Ilya Dryomov

libceph: rename ceph_oloc_oid_to_pg()

2016-05-25T22:36:24Z

Rename ceph_oloc_oid_to_pg() to ceph_object_locator_to_pg(). Emphasise that returned is raw PG and return -ENOENT instead of -EIO if the pool doesn't exist. Signed-off-by: Ilya Dryomov

libceph: variable-sized ceph_object_id

2016-05-25T22:36:22Z

Currently ceph_object_id can hold object names of up to 100 (CEPH_MAX_OID_NAME_LEN) characters. This is enough for all use cases, expect one - long rbd image names: - a format 1 header is named ".rbd" - an object that points to a format 2 header is named "rbd_id." We operate on these potentially long-named objects during rbd map, and, for format 1 images, during header refresh. (A format 2 header name is a small system-generated string.) Lift this 100 character limit by making ceph_object_id be able to point to an externally-allocated string. Apart from being able to work with almost arbitrarily-long named objects, this allows us to reduce the size of ceph_object_id from >100 bytes to 64 bytes. Signed-off-by: Ilya Dryomov

ceph: fix divide-by-zero in __validate_layout()

2014-10-14T19:57:05Z

The 'stripe_unit' field is 64 bits, casting it to 32 bits can result zero. Signed-off-by: Yan, Zheng
