Hi Linus, The following changes since commit 2c85ebc57b3e1817b6ce1a6b703928e113a90442: Linux 5.10 (2020-12-13 14:41:30 -0800) are available in the Git repository at: https://github.com/ceph/ceph-client.git tags/ceph-for-5.11-rc1 for you to fetch changes up to 2f0df6cfa325d7106b8a65bc0e02db1086e3f73b: libceph: drop ceph_auth_{create,update}_authorizer() (2020-12-14 23:21:50 +0100) There is a build conflict caused by the split of crypto/sha.h into crypto/sha1.h and crypto/sha2.h that affects net/ceph/messenger_v2.c. The resolution is to include the latter, done in for-linus-merged just in case. ---------------------------------------------------------------- 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. ---------------------------------------------------------------- Colin Ian King (1): ceph: remove redundant assignment to variable i Ilya Dryomov (34): libceph: include middle_len in process_message() dout libceph: lower exponential backoff delay libceph: don't call reset_connection() on version/feature mismatches libceph: split protocol reset bits out of reset_connection() libceph: rename reset_connection() to ceph_con_reset_session() libceph: clear con->peer_global_seq on RESETSESSION libceph: remove redundant session reset log message libceph: drop msg->ack_stamp field libceph: handle discarding acked and requeued messages separately libceph: change ceph_msg_data_cursor_init() to take cursor libceph: change ceph_con_in_msg_alloc() to take hdr libceph: factor out ceph_con_get_out_msg() libceph: make sure our addr->port is zero and addr->nonce is non-zero libceph: don't export ceph_messenger_{init_fini}() to modules libceph: make con->state an int libceph: rename and export con->state states libceph: rename and export con->flags bits libceph: export zero_page libceph: export remaining protocol independent infrastructure libceph: separate msgr1 protocol implementation libceph: move msgr1 protocol implementation to its own file libceph: move msgr1 protocol specific fields to its own struct libceph: more insight into ticket expiry and invalidation libceph: safer en/decoding of cephx requests and replies libceph, ceph: incorporate nautilus cephx changes libceph: amend cephx init_protocol() and build_request() libceph: drop ac->ops->name field libceph: factor out finish_auth() libceph, ceph: get and handle cluster maps with addrvecs libceph, rbd: ignore addr->type while comparing in some cases libceph: introduce connection modes and ms_mode option libceph, ceph: implement msgr2.1 protocol (crc and secure modes) libceph, ceph: make use of __ceph_auth_get_authorizer() in msgr1 libceph: drop ceph_auth_{create,update}_authorizer() Jeff Layton (15): ceph: don't WARN when removing caps due to blocklisting ceph: make fsc->mount_state an int ceph: add new RECOVER mount_state when recovering session ceph: remove timeout on allowing reconnect after blocklisting ceph: queue MDS requests to REJECTED sessions when CLEANRECOVER is set ceph: fix up some warnings on W=1 builds ceph: acquire Fs caps when getting dir stats ceph: ensure we have Fs caps when fetching dir link count ceph: pass down the flags to grab_cache_page_write_begin ceph: fix inode refcount leak when ceph_fill_inode on non-I_NEW inode fails ceph: when filling trace, call ceph_get_inode outside of mutexes ceph: don't reach into request header for readdir info ceph: take a cred reference instead of tracking individual uid/gid ceph: clean up argument lists to __prepare_send_request and __send_request ceph: implement updated ceph_mds_request_head structure Liu, Changcheng (1): libceph: remove unused port macros Luis Henriques (4): ceph: fix race in concurrent __ceph_remove_cap invocations ceph: downgrade warning from mdsmap decode to debug Revert "ceph: allow rename operation under different quota realms" ceph: add ceph.caps vxattr Xiubo Li (4): ceph: send dentry lease metrics to MDS daemon ceph: add status debugfs file ceph: add ceph.{cluster_fsid/client_id} vxattrs ceph: set osdmap epoch for setxattr drivers/block/rbd.c | 8 +- fs/ceph/addr.c | 6 +- fs/ceph/caps.c | 27 +- fs/ceph/debugfs.c | 20 + fs/ceph/dir.c | 9 +- fs/ceph/inode.c | 41 +- fs/ceph/locks.c | 8 +- fs/ceph/mds_client.c | 280 ++- fs/ceph/mds_client.h | 3 +- fs/ceph/mdsmap.c | 25 +- fs/ceph/metric.c | 18 +- fs/ceph/metric.h | 14 + fs/ceph/quota.c | 58 +- fs/ceph/super.c | 14 +- fs/ceph/super.h | 7 +- fs/ceph/xattr.c | 81 +- include/linux/ceph/auth.h | 68 +- include/linux/ceph/ceph_features.h | 11 +- include/linux/ceph/ceph_fs.h | 44 +- include/linux/ceph/decode.h | 8 + include/linux/ceph/libceph.h | 11 +- include/linux/ceph/mdsmap.h | 2 +- include/linux/ceph/messenger.h | 285 ++- include/linux/ceph/msgr.h | 66 +- include/linux/ceph/osdmap.h | 4 +- net/ceph/Kconfig | 3 + net/ceph/Makefile | 3 +- net/ceph/auth.c | 408 ++++- net/ceph/auth_none.c | 5 +- net/ceph/auth_x.c | 298 +++- net/ceph/auth_x_protocol.h | 3 +- net/ceph/ceph_common.c | 63 + net/ceph/ceph_strings.c | 28 + net/ceph/crypto.h | 3 + net/ceph/decode.c | 101 ++ net/ceph/messenger.c | 2252 +++++------------------ net/ceph/messenger_v1.c | 1506 ++++++++++++++++ net/ceph/messenger_v2.c | 3443 ++++++++++++++++++++++++++++++++++++ net/ceph/mon_client.c | 320 +++- net/ceph/osd_client.c | 111 +- net/ceph/osdmap.c | 45 +- 41 files changed, 7371 insertions(+), 2339 deletions(-) create mode 100644 net/ceph/messenger_v1.c create mode 100644 net/ceph/messenger_v2.c
