Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs updates from Steve French: "Various CIFS/SMB2/SMB3 updates for 3.11. Includes bug fixes - SMB3 support should be much more stable with key DFS fix and also signing possible now (although is more work to do to get SMB3 signing working well with multiuser). Mounts using the new SMB 3.02 dialect can now be done (specify "vers=3.02" on mount) against the most current Microsoft systems. Also includes a big cleanup of the cifs/smb2/smb3 authentication code from Jeff which fixes some long standing problems with the way allowed authentication flavors and signing are configured. Some followon patches later in the cycle will clean up allocation of structures for the various security mechanisms depending on what dialect is chosen (reduces memory usage a little) and to add support for the secure negotiate fsctl (for smb3) which prevents downgrade attacks." * 'for-next' of git://git.samba.org/sfrench/cifs-2.6: (39 commits) cifs: fill TRANS2_QUERY_FILE_INFO ByteCount fields cifs: fix SMB2 signing enablement in cifs_enable_signing [CIFS] Fix build warning [CIFS] SMB3 Signing enablement [CIFS] Do not set DFS flag on SMB2 open [CIFS] fix static checker warning cifs: try to handle the MUST SecurityFlags sanely When server doesn't provide SecurityBuffer on SMB2Negotiate pick default Handle big endianness in NTLM (ntlmv2) authentication revalidate directories instiantiated via FIND_* in order to handle DFS referrals SMB2 FSCTL and IOCTL worker function Charge at least one credit, if server says that it supports multicredit Remove typo Some missing share flags cifs: using strlcpy instead of strncpy Update headers to update various SMB3 ioctl definitions Update cifs version number Add ability to dipslay SMB3 share flags and capabilities for debugging Add some missing SMB3 and SMB3.02 flags Add SMB3.02 dialect support ...
