7054217a79 vfs/time_audit: use duration we get from the async backend
Finally! The previous commits changed the VFS and the async backend to
pass the duration of an aync operation up the stack.

We now can use this value instead of doing our own sampling which avoids
the following problem:

1. SMB2 read request received, added to the async queue

2. SMB2 create_file request comes in, is processed and blocks for N
   seconds in open()

3. async read completes in the dispatcher thread, completion callback
   will be called when we enter the main tevent loop

4. open() completes after N seconds

5. main tevent event loop is entered, async results are processed

6. async read result is processed, time sampling will include the N
   seconds blocked in open()

67ee428467 vfs: add snapshot create/delete hooks
This change adds three new VFS hooks covering snapshot manipulation:
- snap_check_path
  Check whether a path supports snapshots.
- snap_create
  Request the creation of a snapshot of the provided path.
- snap_delete
  Request the deletion of a snapshot.

These VFS call-outs will be used in future by Samba's File Server Remote
VSS Protocol (FSRVP) server.

MS-FSVRP states:
  At any given time, Windows servers allow only one shadow copy set to
  be going through the creation process.
Therefore, only provide synchronous hooks for now, which can be
converted to asynchronous _send/_recv functions when the corresponding
DCE/RPC server infrastructure is in place.

12c0b6bf40 s3/vfs: change fallocate mode flags from enum->uint32_t
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.

d8d5d4c742 vfs: add [GET/SET]_COMPRESSION hooks
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.

Check whether the request source offset + length exceeds the current
size. Return STATUS_INVALID_VIEW_SIZE under such a condition, matching

This makes it clear which context the returned SD is allocated on, as

e25830dcd8 s3-smbd: Remove sys_acl_*() VFS wrapper functions
We no longer do struct smb_acl_t manipuations via the VFS layer,
which is now reduced to handling the get/set functions.

The only backend that implemented these functions (aside from audit)
was the vfs_default module calling the sys_acl code.  The various ACL
implementation modules either worked on the fully initilaised
smb_acl_t object or on NT ACLs.

This not only makes the operation of the posix ACL code more efficient
(as allocation and free is not put via the VFS), it makes it easier to
test and removes the fantasy that a module could safely redefine this
structure or the behaviour here.

The smb_acls.idl now defines the structure, and it is now allocated
with talloc.

These operations were originally added to the VFS in commit
3bb219161a.
