  ceph: don't drop message if it contains more data than expected (2018-08-13 17:55:44 +0200)

----------------------------------------------------------------
The main things are support for cephx v2 authentication protocol and
basic support for rbd images within namespaces (myself).  Also included
y2038 conversion patches from Arnd, a pile of miscellaneous fixes from
Chengguang and Zheng's feature bit infrastructure for the filesystem.

----------------------------------------------------------------
Arnd Bergmann (5):
      libceph: use timespec64 in for keepalive2 and ticket validity
      ceph: stop using current_kernel_time()
      ceph: use timespec64 for inode timestamp
      libceph: use timespec64 for r_mtime
      ceph: use timespec64 for r_stamp

Chengguang Xu (14):
      ceph: add retry logic for error -ERANGE in ceph_get_acl()
      ceph: restore ctime as well in the case of restoring old mode
      libceph: stop parsing when a bad int arg is detected
      ceph: return errors from posix_acl_equiv_mode() correctly
      ceph: add d_drop for some error cases in ceph_mknod()
      ceph: add d_drop for some error cases in ceph_symlink()
      ceph: add new field max_file_size in ceph_fs_client
      ceph: add additional range check in ceph_fallocate()
      ceph: add additional offset check in ceph_write_iter()
      ceph: add additional size check in ceph_setattr()
      ceph: compare fsc->max_file_size and inode->i_size for max file size limit
      ceph: change to void return type for __do_request()
      ceph: refactor ceph_unreserve_caps()
      ceph: refactor error handling code in ceph_reserve_caps()

Ilya Dryomov (14):
      libceph: make ceph_osdc_notify{,_ack}() payload_len u32
      libceph: change ceph_pagelist_encode_string() to take u32
      libceph: amend "bad option arg" error message
      rbd: pass rbd_spec into parse_rbd_opts_token()
      rbd: support for images within namespaces
      libceph: remove now unused ceph_{en,de}code_timespec()
      libceph: store ceph_auth_handshake pointer in ceph_connection
      libceph: factor out __prepare_write_connect()
      libceph: factor out __ceph_x_decrypt()
      libceph: factor out encrypt_authorizer()
      libceph: add authorizer challenge
      libceph: implement CEPHX_V2 calculation mode
      libceph: check authorizer reply/challenge length before reading
      libceph: weaken sizeof check in ceph_x_verify_authorizer_reply()

Souptick Joarder (1):
      ceph: adding new return type vm_fault_t

Stephen Hemminger (1):
      ceph: fix whitespace

Yan, Zheng (3):
      ceph: fix incorrect use of strncpy
      ceph: support cephfs' own feature bits
      ceph: don't drop message if it contains more data than expected

YueHaibing (2):
      libceph: remove unnecessary non NULL check for request_key
