Merge tag 'ceph-for-5.11-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "The big ticket item here is support for msgr2 on-wire protocol, which adds the option of full in-transit encryption using AES-GCM algorithm (myself). On top of that we have a series to avoid intermittent errors during recovery with recover_session=clean and some MDS request encoding work from Jeff, a cap handling fix and assorted observability improvements from Luis and Xiubo and a good number of cleanups. Luis also ran into a corner case with quotas which sadly means that we are back to denying cross-quota-realm renames" * tag 'ceph-for-5.11-rc1' of git://github.com/ceph/ceph-client: (59 commits) libceph: drop ceph_auth_{create,update}_authorizer() libceph, ceph: make use of __ceph_auth_get_authorizer() in msgr1 libceph, ceph: implement msgr2.1 protocol (crc and secure modes) libceph: introduce connection modes and ms_mode option libceph, rbd: ignore addr->type while comparing in some cases libceph, ceph: get and handle cluster maps with addrvecs libceph: factor out finish_auth() libceph: drop ac->ops->name field libceph: amend cephx init_protocol() and build_request() libceph, ceph: incorporate nautilus cephx changes libceph: safer en/decoding of cephx requests and replies libceph: more insight into ticket expiry and invalidation libceph: move msgr1 protocol specific fields to its own struct libceph: move msgr1 protocol implementation to its own file libceph: separate msgr1 protocol implementation libceph: export remaining protocol independent infrastructure libceph: export zero_page libceph: rename and export con->flags bits libceph: rename and export con->state states libceph: make con->state an int ...
