2013-02-08s3: Make SMB2_GETINFO multi-volume aware.Ira Cooper3-9/+20
Not all shares are a single volume. Some actually expose multiple volumes under a single share. In these cases showing the amount of space free as the space free at the base of the directory heirarchy is wrong.

2013-01-28Fix bug #9588 - ACLs are not inherited to directories for DFS shares.Jeremy Allison1-0/+13
We can return with NT_STATUS_OK in an error code path. This has a really strange effect in that it prevents the ACL editor in Windows XP from recursively changing ACE entries on sub-directories after a change in a DFS-root share (we end up returning a path that looks like: \\IPV4\share1\xptest/testdir with a mixture of Windows and POSIX pathname separators).

2013-01-25Fix bug #9587 - archive flag is always set on directories.Jeremy Allison1-1/+2
Creating a directory to a Samba share sets the attributes to 'D' only (correct) - only when creating a new file should the 'A' attribute be set. However, doing a rename of that directory sets the 'A' attribute in error. This should only be done on a file rename. smbclient regression test to follow.

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>
