2013-01-19Fix warnings with mismatched sizes in arguments to DEBUG statements.Jeremy Allison1-8/+8
This can cause compile errors on 32-bit systems. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org> Autobuild-User(master): Stefan Metzmacher <metze@samba.org> Autobuild-Date(master): Sat Jan 19 12:14:13 CET 2013 on sn-devel-104
2013-01-18Remove locking across the lifetime of the copychunk call.Jeremy Allison1-116/+1
Previous commit handles this around each read/write call. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org> Autobuild-User(master): David Disseldorp <ddiss@samba.org> Autobuild-Date(master): Fri Jan 18 01:47:01 CET 2013 on sn-devel-104

For printer, ipc$ connections, and directory handles. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>
2013-01-18Move handle checking code to copychunk_check_handles().Jeremy Allison1-21/+37
Planning to add extra checks to ensure we don't attempt copychunk on printer or IPC$ handles. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>
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
2013-01-16smb2_ioctl: track copychunk response output stateDavid Disseldorp1-16/+38
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: only pass through to VFS on a valid fspDavid Disseldorp1-13/+17
A null fsp is dereferenced on VFS call. 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>
2013-01-16smb2_ioctl: split ioctl handler code on device typeDavid Disseldorp1-0/+173
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>
