s3/vfs: change fallocate mode flags from enum->uint32_t

2015-03-09T20:27:07+00:00

The Linux fallocate syscall offers a mode parameter which can take the
following flags:
FALLOC_FL_KEEP_SIZE
FALLOC_FL_PUNCH_HOLE (since 2.6.38)
FALLOC_FL_COLLAPSE_RANGE (since 3.15)
FALLOC_FL_ZERO_RANGE (since 3.14)

The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified
alongside FALLOC_FL_KEEP_SIZE.

Samba currently takes a vfs_fallocate_mode enum parameter for the VFS
fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This
commit changes the fallocate hook such that it accepts a uint32_t flags
parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

s3/vfs: remove unused SMB_VFS_DISK_FREE() small_query parameter

2015-02-17T04:37:20+00:00

The small_query parameter for SMB_VFS_DISK_FREE() was, prior to the
previous commit, used to obtain 16-bit wide free-space information for
the deprecated dskattr SMB_COM_QUERY_INFORMATION_DISK command.

With the dskattr handler now performing the 16-bit collapse directly,
the small_query parameter can be removed from the entire code path.

s3:vfs: add SMB_VFS_READDIR_ATTR()

2014-12-04T21:11:07+00:00

SMB_VFS_READDIR_ATTR is a last minute hook to fetch additional metadata
for a directory entry when we're already marshalling the SMB reply
buffer.

This would be used, when there's a need to repurpose some fields in the
the reply, like it's done with Apple's SMB2 extension "AAPL".

vfs: add [GET/SET]_COMPRESSION hooks

2013-11-22T16:56:45+00:00

The VFS interfaces are sychronous, as the operations only modify
meta-data.
These hooks are dependent on support for transparent compression by the
underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST.
Support for other filesystems providing transparent comression, such as
Btrfs and ZFS, can be added in future.

The get_compression function takes fsp and smb_fname arguments. The
smb_fname argument is needed due to the current dosmode() code-path.

s3-vfs: add copy_chunk vfs hooks

2013-01-16T22:15:06+00:00

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.
