2013-10-25smb2_ioctl: add support for FSCTL_SRV_COPYCHUNK_WRITEDavid Disseldorp1-10/+34
FSCTL_SRV_COPYCHUNK can only be used when the client has the copy-chunk target file open with FILE_WRITE_DATA and FILE_READ_DATA. FSCTL_SRV_COPYCHUNK_WRITE requires only FILE_WRITE_DATA access on the target, and is therefore suitable for cp --reflink, which opens the target file O_WRONLY.

2013-01-16smb2_ioctl: copychunk CHECK_READ and CHECK_WRITEDavid Disseldorp1-0/+25
[MS-SMB2] 3.3.5.15.6 Handling a Server-Side Data Copy Request, specifies that the copychunk destination file handle be granted FILE_WRITE_DATA and FILE_READ_DATA access. FILE_READ_DATA access must also be granted on the copychunk source file, which may be done implicitly with execute permission. Reviewed by: Jeremy Allison <jra@samba.org>

2013-01-16smb2_ioctl: perform locking around copychunk requestsDavid Disseldorp1-17/+137
For each chunk in a copychunk request, take a read and write lock on the source and destination files respectively. Also change the resume key format to use a combination of the persistent and volatile handles. Thanks to Metze for his help on this. Reviewed by: Jeremy Allison <jra@samba.org>
2013-01-16smb2_ioctl: add support for FSCTL_SRV_COPYCHUNKDavid Disseldorp1-4/+231
SMB2 clients can issue FSCTL_SRV_COPYCHUNK requests in order to copy data between files on the server side only, rather than reading data then writing back from the client. FSCTL_SRV_COPYCHUNK is used by default for Explorer SMB2 file copies on Windows Server 2012. 2.2.32.1 SRV_COPYCHUNK_RESPONSE in [MS-SMB2] describes the requirement for the server to provide maximum copychunk request size limits in ioctl responses carrying STATUS_INVALID_PARAMETER.

2013-01-16smb2_ioctl: add FSCTL_SRV_REQUEST_RESUME_KEY supportDavid Disseldorp1-2/+47
Use existing ioctl IDL infrastructure for marshalling. Support for this ioctl is a prerequisite for FSCTL_SRV_COPYCHUNK handling. The client-opaque resume key is constructed using the server side dev/inode file identifier. Reviewed by: Jeremy Allison <jra@samba.org>
