libceph, rbd, ceph: convert to use the new mount API

2019-11-27T21:28:37Z

Convert the ceph filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information. [ Numerous string handling, leak and regression fixes; rbd conversion was particularly broken and had to be redone almost from scratch. ] Signed-off-by: David Howells Signed-off-by: Jeff Layton Signed-off-by: Ilya Dryomov

Merge tag 'ceph-for-5.3-rc1' of git://github.com/ceph/ceph-client

2019-07-18T18:05:25Z

Pull ceph updates from Ilya Dryomov: "Lots of exciting things this time! - support for rbd object-map and fast-diff features (myself). This will speed up reads, discards and things like snap diffs on sparse images. - ceph.snap.btime vxattr to expose snapshot creation time (David Disseldorp). This will be used to integrate with "Restore Previous Versions" feature added in Windows 7 for folks who reexport ceph through SMB. - security xattrs for ceph (Zheng Yan). Only selinux is supported for now due to the limitations of ->dentry_init_security(). - support for MSG_ADDR2, FS_BTIME and FS_CHANGE_ATTR features (Jeff Layton). This is actually a single feature bit which was missing because of the filesystem pieces. With this in, the kernel client will finally be reported as "luminous" by "ceph features" -- it is still being reported as "jewel" even though all required Luminous features were implemented in 4.13. - stop NULL-terminating ceph vxattrs (Jeff Layton). The convention with xattrs is to not terminate and this was causing inconsistencies with ceph-fuse. - change filesystem time granularity from 1 us to 1 ns, again fixing an inconsistency with ceph-fuse (Luis Henriques). On top of this there are some additional dentry name handling and cap flushing fixes from Zheng. Finally, Jeff is formally taking over for Zheng as the filesystem maintainer" * tag 'ceph-for-5.3-rc1' of git://github.com/ceph/ceph-client: (71 commits) ceph: fix end offset in truncate_inode_pages_range call ceph: use generic_delete_inode() for ->drop_inode ceph: use ceph_evict_inode to cleanup inode's resource ceph: initialize superblock s_time_gran to 1 MAINTAINERS: take over for Zheng as CephFS kernel client maintainer rbd: setallochint only if object doesn't exist rbd: support for object-map and fast-diff rbd: call rbd_dev_mapping_set() from rbd_dev_image_probe() libceph: export osd_req_op_data() macro libceph: change ceph_osdc_call() to take page vector for response libceph: bump CEPH_MSG_MAX_DATA_LEN (again) rbd: new exclusive lock wait/wake code rbd: quiescing lock should wait for image requests rbd: lock should be quiesced on reacquire rbd: introduce copyup state machine rbd: rename rbd_obj_setup_*() to rbd_obj_init_*() rbd: move OSD request allocation into object request state machines rbd: factor out __rbd_osd_setup_discard_ops() rbd: factor out rbd_osd_setup_copyup() rbd: introduce obj_req->osd_reqs list ...

rbd: support for object-map and fast-diff

2019-07-08T12:01:45Z

Speed up reads, discards and zeroouts through RBD_OBJ_FLAG_MAY_EXIST and RBD_OBJ_FLAG_NOOP_FOR_NONEXISTENT based on object map. Invalid object maps are not trusted, but still updated. Note that we never iterate, resize or invalidate object maps. If object-map feature is enabled but object map fails to load, we just fail the requester (either "rbd map" or I/O, by way of post-acquire action). Signed-off-by: Ilya Dryomov

This will be used for loading object map. rbd_obj_read_sync() isn't suitable because object map must be accessed through class methods. Signed-off-by: Ilya Dryomov Reviewed-by: Dongsheng Yang Reviewed-by: Jeff Layton
