We have encountered failures when When testing smb2 mounts on ppc64 machines when using both Samba as well as Windows 2012. On poking around, the problem was determined to be caused by the high endian MessageID passed in the header for smb2. On checking the corresponding MID for smb1 is converted to LE before being sent on the wire. We have tested this patch successfully on a ppc64 machine.

Implement FALLOC_FL_PUNCH_HOLE (which does not change the file size fortunately so this matches the behavior of the equivalent SMB3 fsctl call) for SMB3 mounts. This allows "fallocate -p" to work. It requires that the server support setting files as sparse (which Windows allows). Signed-off-by: NSteve French <smfrench@gmail.com>

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." For more explanation see 2.2.31.4 of MS-SMB2 or http://blogs.msdn.com/b/openspecification/archive/2012/06/28/smb3-secure-dialect-negotiation.aspxReviewed-by: NPavel Shilovsky <piastry@etersoft.ru> Signed-off-by: NSteve French <smfrench@gmail.com>

This first patch adds the ability for us to do a server side copy (ie fast copy offloaded to the server to perform, aka refcopy) "cp --reflink" of one file to another located on the same server. This is much faster than traditional copy (which requires reading and writing over the network and extra memcpys). This first version is not going to be copy files larger than about 1MB (to Samba) until I add support for multiple chunks and for autoconfiguring the chunksize. It includes: 1) processing of the ioctl 2) marshalling and sending the SMB2/SMB3 fsctl over the network 3) simple parsing of the response It does not include yet (these will be in followon patches to come soon): 1) support for multiple chunks 2) support for autoconfiguring and remembering the chunksize 3) Support for the older style copychunk which Samba 4.1 server supports (because this requires write permission on the target file, which cp does not give you, apparently per-posix). This may require a distinct tool (other than cp) and other ioctl to implement. Reviewed-by: NPavel Shilovsky <piastry@etersoft.ru> Signed-off-by: NSteve French <smfrench@gmail.com>

An earlier patch allowed setting the per-file compression flag "chattr +c filename" on an smb2 or smb3 mount, and also allowed lsattr to return whether a file on a cifs, or smb2/smb3 mount was compressed. This patch extends the ability to set the per-file compression flag to the cifs protocol, which uses a somewhat different IOCTL mechanism than SMB2, although the payload (the flags stored in the compression_state) are the same.

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).

Allow cifs/smb2/smb3 to return whether or not a file is compressed via lsattr, and allow SMB2/SMB3 to set the per-file compression flag ("chattr +c filename" on an smb3 mount). Windows users often set the compressed flag (it can be done from the desktop and file manager). David Disseldorp has patches to Samba server to support this (at least on btrfs) which are complementary to this Signed-off-by: NSteve French <smfrench@gmail.com>

This worker function is needed to send SMB2 fsctl (and ioctl) requests including: validating negotiation info (secure negotiate) querying the servers network interfaces copy offload (refcopy) Followon patches for the above three will use this. This patch also does general validation of the response. In the future, as David Disseldorp notes, for the copychunk ioctl case, we will want to enhance the response processing to allow returning the chunk request limits to the caller (even though the server returns an error, in that case we would return data that the caller could use - see 2.2.32.1). See MS-SMB2 Section 2.2.31 for more details on format of fsctl. Acked-by: NPavel Shilovsky <piastry@etersoft.ru> Signed-off-by: NSteve French <smfrench@gmail.com>
