SMB2 servers indicates the end of a directory search with STATUS_NO_MORE_FILE error code that is not processed now. This causes generic/257 xfstest to fail. Fix this by triggering the end of search by this error code in SMB2_query_directory. Also when negotiating CIFS protocol we tell the server to close the search automatically at the end and there is no need to do it itself. In the case of SMB2 protocol, we need to close it explicitly - separate close directory checks for different protocols.

Many Linux filesystes make a file "sparse" when extending a file with ftruncate. This does work for CIFS to Samba (only) but not for SMB2/SMB3 (to Samba or Windows) since there is a "set sparse" fsctl which is supposed to be sent to mark a file as sparse. This patch marks a file as sparse by sending this simple set sparse fsctl if it is extended more than 2 pages. It has been tested to Windows 8.1, Samba and various SMB2/SMB3 servers which do support setting sparse (and MacOS which does not appear to support the fsctl yet). If a server share does not support setting a file as sparse, then we do not retry setting sparse on that share. The disk space savings for sparse files can be quite large (even more significant on Windows servers than Samba).

When mounting from a Windows 2012R2 server, we hit the following problem: 1) Mount with any of the following versions - 2.0, 2.1 or 3.0 2) unmount 3) Attempt a mount again using a different SMB version >= 2.0. You end up with the following failure: Status code returned 0xc0000203 STATUS_USER_SESSION_DELETED CIFS VFS: Send error in SessSetup = -5 CIFS VFS: cifs_mount failed w/return code = -5 I cannot reproduce this issue using a Windows 2008 R2 server. This appears to be caused because we use the same client guid for the connection on first mount which we then disconnect and attempt to mount again using a different protocol version. By generating a new guid each time a new connection is Negotiated, we avoid hitting this problem. Signed-off-by: NSachin Prabhu <sprabhu@redhat.com> Signed-off-by: NSteve French <smfrench@gmail.com>

When we are running SMB3 or SMB3.02 connections which are signed we need to validate the protocol negotiation information, to ensure that the negotiate protocol response was not tampered with. Add the missing FSCTL which is sent at mount time (immediately after the SMB3 Tree Connect) to validate that the capabilities match what we think the server sent. "Secure dialect negotiation is introduced in SMB3 to protect against man-in-the-middle attempt to downgrade dialect negotiation. The idea is to prevent an eavesdropper from downgrading the initially negotiated dialect and capabilities between the client and the server."

This third version of the patch, incorparating feedback from David Disseldorp extends the ability of copychunk (refcopy) over smb2/smb3 mounts to handle servers with smaller than usual maximum chunk sizes and also fixes it to handle files bigger than the maximum chunk sizes In the future this can be extended further to handle sending multiple chunk requests in on SMB2 ioctl request which will further improve performance, but even with one 1MB chunk per request the speedup on cp is quite large.

In SMB3 it is now possible to query the file system alignment info, and the preferred (for performance) sector size and whether the underlying disk has no seek penalty (like SSD). Query this information at mount time for SMB3, and make it visible in /proc/fs/cifs/DebugData for debugging purposes. This alignment information and preferred sector size info will be helpful for the copy offload patches to setup the right chunks in the CopyChunk requests. Presumably the knowledge that the underlying disk is SSD could also help us make better readahead and writebehind decisions (something to look at in the future).

Since session key for smb1 is per smb connection, once a very first sesion is established, there is no need for key exchange during subsequent session setups. As a result, smb1 session setup code sets this variable as false.
