2013-01-17smb2_ioctl: copychunk request max output validationDavid Disseldorp1-0/+12
Check that the copychunk ioctl request maximum output specified by the client is large enough to hold copychunk response data. Reviewed by: Jeremy Allison <jra@samba.org> Autobuild-User(master): Jeremy Allison <jra@samba.org> Autobuild-Date(master): Thu Jan 17 00:59:44 CET 2013 on sn-devel-104

Treat the response data independent to the status. Reviewed by: Jeremy Allison <jra@samba.org>
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: remove ioctl error response assumptionsDavid Disseldorp1-17/+57
MS-SMB2 3.3.4.4 documents cases where a ntstatus indicating an error should not be considered a failure. In such a case the output data buffer should be sent to the client rather than an error response packet. Add a new fsctl copy_chunk test to confirm field limits are sent back in response to an oversize chunk request. 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. Reviewed by: Jeremy Allison <jra@samba.org>
2013-01-16s3-vfs: add copy_chunk vfs hooksDavid Disseldorp1-2/+24
copy_chunk copies n bytes from a source file at a specific offset to a destination file at a given offset. This interface will be used in handling smb2 FSCTL_SRV_COPYCHUNK ioctl requests. Use a pread/pwrite loop in vfs_default, so that requests referring to the same src and dest file are possible. Provide send and receive hooks for copy chunk VFS interface, allowing asynchronous behaviour. Check whether the request source offset + length exceeds the current size. Return STATUS_INVALID_VIEW_SIZE under such a condition, matching Windows server behaviour. Reviewed by: Jeremy Allison <jra@samba.org>
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>
2013-01-16smb2_ioctl: split ioctl handler code on device typeDavid Disseldorp6-355/+676
Add per device type ioctl handler source files for FSCTL_DFS, FSCTL_FILESYSTEM, FSCTL_NAMED_PIPE and FSCTL_NETWORK_FILESYSTEM. Reviewed by: Jeremy Allison <jra@samba.org>

get_deferred_open_message_state_smb2() is buggy in that it is checking the wrong things to determine if an open is in the deferred state. It checks if (smb2req->async_te == NULL) which is incorrect, as we're not always async in a deferred open - remove this. It should check instead state->open_was_deferred as this is explicity set to 'true' when an open is going deferred, so add this check.
