set integrity increases reliability of files stored on SMB3 servers. Add ioctl to allow setting this on files on SMB3 and later mounts. Signed-off-by: Steve French

Add reflink copy over SMB3.11 with new FSCTL_DUPLICATE_EXTENTS

2015-06-29T02:15:38+00:00

Getting fantastic copy performance with cp --reflink over SMB3.11 using the new FSCTL_DUPLICATE_EXTENTS. This FSCTL was added in the SMB3.11 dialect (testing was against REFS file system) so have put it as a 3.11 protocol specific operation ("vers=3.1.1" on the mount). Tested at the SMB3 plugfest in Redmond. It depends on the new FS Attribute (BLOCK_REFCOUNTING) which is used to advertise support for the ability to do this ioctl (if you can support multiple files pointing to the same block than this refcounting ability or equivalent is needed to support the new reflink-like duplicate extent SMB3 ioctl.

Add SMB3.11 mount option synonym for new dialect

2015-06-28T03:28:11+00:00

Most people think of SMB 3.1.1 as SMB version 3.11 so add synonym for "vers=3.1.1" of "vers=3.11" on mount. Also make sure that unlike SMB3.0 and 3.02 we don't send validate negotiate on mount (it is handled by negotiate contexts) - add list of SMB3.11 specific functions (distinct from 3.0 dialect).

Allow parsing vers=3.11 on cifs mount

2015-06-28T03:23:32+00:00

Parses and recognizes "vers=3.1.1" on cifs mount and allows sending 0x0311 as a new CIFS/SMB3 dialect. Subsequent patches will add the new negotiate contexts and updated session setup Reviewed-by: Jeff Layton Signed-off-by: Steve French

cifs: smb2_clone_range() - exit on unhandled error

2015-03-21T15:56:22+00:00

While attempting to clone a file on a samba server, we receive a STATUS_INVALID_DEVICE_REQUEST. This is mapped to -EOPNOTSUPP which isn't handled in smb2_clone_range(). We end up looping in the while loop making same call to the samba server over and over again. The proposed fix is to exit and return the error value when encountered with an unhandled error.

Convert MessageID in smb2_hdr to LE

2014-12-14T20:55:45+00:00

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. Signed-off-by: Sachin Prabhu

Add support for original fallocate

2014-12-08T04:17:19+00:00

In many cases the simple fallocate call is a no op (since the file is already not sparse) or can simply be converted from a sparse to a non-sparse file if we are fallocating the whole file and keeping the size. Signed-off-by: Steven French
