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()

According to discussions with dochelp@microsoft.com, an SMB
server should ignore an SVHDX_OPEN_DEVICE_CONTEXT or
SVHDX_OPEN_DEVICE_CONTEXT_V2 create context if it does not
support the RSVD protocol. This is contrary to [MS-SMB2] rev 48.0
which states (3.3.5.9.14) that the open should fail in this case.
Failing the create fails Windows backup if the SMB dialect is
SMB3.0.2 or higher.
Hopefully a new revision of MS-SMB2 will clear this up in the future.
Meanwhile, this patch modifies smbd to ignore the
SVHDX_OPEN_DEVICE_CONTEXT by default. This can be overriden by a VFS
module if a VFS module adds support for RSVD.

It can be useful for shares mounted on top of a remote file

Offline files change the behavior of Windows explorer, and
prevent it from peeking inside folders just for the sake of
drawing a nice icon of them. This greatly reduces the number

Use a dynamically allocated copy_chunk buffer size with an upper bound

The SMB2 protocol level maximum allowed copy_chunk size is 1 MB, that's
what will be used as buffer size in the typical case.
With the AAPL copyfile extension the requested copy_chunk size is the
size whole file, which would then make use of a larger buffer up to the

vfs_fruit adds a wildcard path "._*" to the vetolist in order to prevent
client access to ._ AppleDouble files created internally by vfs_fruit
for storing the Mac resource fork stream.
Unfortunately there are legitimite use cases where an OS X client may
want to use such filenames, extracting ZIP archives (where the archive
contains ._ files) being one of them.
A possible simple solution to this problem would be to not veto ._ files
in the first place, even though that exposes internally created ._ files
which the client shouldn't be able to access.

Based on <https://code.google.com/p/vfs-unityed-media/>.
The existing VFS module media_harmony has some problems relative to Avid
media sharing:
Avid looks at the modification time of the ingest directory. Since
media_harmony has everyone using the same directory, users (or client
systems) have to somehow create "fake" directories with special names
and then media_harmony returns the mod time of those fake directories
for the different clients rather than the actual mod time of the
communal ingest directory.
To make matters worse, users then have to have a special utility or
understand how to update the modtime on these specially named
directories. Otherwise, their client system will never update the
indexes to show new media.
To make it even worse than that, Avid creates new directories on the
fly, so you can't just set this up statically at the beginning. Avid
will silently create a new directory and your reindexing problems will
start all over until you create new fake directories.
With unityed_media:
* there are no reindexes between clients
* clients don't need to know which directories have been created for
them, it's automatic.
* clients never have to reindex other systems directories.
* unityed_media let's each client have their own directories.
* unityed_media works much more like Avid's own ISIS servers work.
A module option controls which name is appended to client specific
paths: the username, the hostname (will not work with OS X) or the
client's IP.

This fixes an incompatible pointer warning which uncovered
a real bug. This caller was missed when converting the function.
This fix is only temporary, since we use fsp->sconn->client->connections
which is supposed to be the start of the list of transport connections
by a given client treated by this smbd process. Currently there is only
one such connection, but with multi-channel there might be more. So
we will need to improve this in the future.

This module provides enhanced compatibility with Apple SMB clients and
interoperability with a Netatalk 3 AFP fileserver.
The module intercepts the OS X special streams "AFP_AfpInfo" and
"AFP_Resource" and handles them in a special way. All other named
streams are deferred to vfs_streams_xattr.
The OS X client maps all NTFS illegal characters to the Unicode
private range. This module optionally stores the charcters using their
native ASCII encoding.
Open modes are optionally checked against Netatalk AFP share modes.
The "AFP_AfpInfo" named stream is a binary blob containing OS X
extended metadata for files and directories. This module optionally
reads and stores this metadata in a way compatible with Netatalk 3
which stores the metadata in an EA "org.netatalk.metadata". Cf
source3/include/MacExtensions.h for a description of the binary blobs
content.
The "AFP_Resource" named stream may be arbitrarily large, thus it
can't be stored in an EA on most filesystem. ZFS on Solaris is an
exception to the rule, because it there EAs can be of any size and EAs
are first-class filesystem objects that can be used with normal file
syscalls like open(), read(), write(), fcntl() asf. This module stores
the AFP_Resource stream in an AppleDouble file, prepending "._" to the
filename. On Solaris and ZFS the stream is optionally stored in an EA
"org.netatalk.ResourceFork".

Now that the vfs_private cache is never read in vfs_gpfs, there is

This was used as a cache for offline-info in the stat buffer.
But as the implementation of gpfs_is_offline() showed, this cache
does not always carry valid information when the stat itself is valid
(since at least one call goes to fstatat() directly, circumventing
the vfs).
So the correct thing is to always call SMB_VFS_IS_OFFLINE()
when checking whether a file is offline. For the pread and pwrite
calls, we need to call IS_OFFLINE before the actual read
and check afterwards if the file was offline before (as a basis
whether to send notifications).

In is_offline(), check whether the winAttrs are filled with bits
outside 0xFFFF and log it prominently: Since GPFS only
fills 0xFFFF, this could be due to an uninitialized buffer
(or another vfs module filling vfs_private? ...).

There is a problem of flapping offline due to uninitialized
stat buffers. Due to a optimization in vfswrap_readdir which
directly calling fastatat (i.e. not through vfs), marking the
stat buffer valid, there is nothing this module can do about
it and hence can not currently not rely on the vaildity of
the stat buffer.
By always calling out to GPFS even when the stat buffer is
flagged valid, we can always return correct offline information,
thereby sacrificing the readdir optimization.
