When a server returns the optional flag SMB_SHARE_IS_IN_DFS in response
to a tree connect, cifs_build_path_to_root() will return a pathname
which includes the hostname. This causes problems with cifs_get_root()
which separates each component and does a lookup for each component of
the path which in this case will incorrectly include looking up the
hostname component as a path component.
We encountered a problem with dfs shares hosted by a Netapp. When
connecting to nodes pointed to by the DFS share. The tree connect for
these nodes return SMB_SHARE_IS_IN_DFS resulting failures in lookup
in cifs_get_root().

With commit 2b149f119 many things have been fixed/introduced.
However, the default behaviour for RawNTLMSSP authentication
seems to be wrong in case the domain is not passed on the command line.
The main points (see below) of the patch are:
- It alignes behaviour with Windows clients
- It fixes backward compatibility
- It fixes UPN
I compared this behavour with the one from a Windows 10 command line
client. When no domains are specified on the command line, I traced
the packets and observed that the client does send an empty
domain to the server.
In the linux kernel case, the empty domain is replaced by the
primary domain communicated by the SMB server.
This means that, if the credentials are valid against the local server
but that server is part of a domain, then the kernel module will
ask to authenticate against that domain and we will get LOGON failure.
I compared the packet trace from the smbclient when no domain is passed
and, in that case, a default domain from the client smb.conf is taken.
Apparently, connection succeeds anyway, because when the domain passed
is not valid (in my case WORKGROUP), then the local one is tried and
authentication succeeds. I tried with any kind of invalid domain and
the result was always a connection.
So, trying to interpret what to do and picking a valid domain if none
is passed, seems the wrong thing to do.
To this end, a new option "domainauto" has been added in case the
user wants a mechanism for guessing.
Without this patch, backward compatibility also is broken.
With kernel 3.10, the default auth mechanism was NTLM.
One of our testing servers accepted NTLM and, because no
domains are passed, authentication was local.
Moving to RawNTLMSSP forced us to change our command line
to add a fake domain to pass to prevent this mechanism to kick in.
For the same reasons, UPN is broken because the domain is specified
in the username.
The SMB server will work out the domain from the UPN and authenticate
against the right server.
Without the patch, though, given the domain is empty, it gets replaced
with another domain that could be the wrong one for the authentication.

Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.
The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.
- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.
- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.
- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.
- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.
- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
which are bio (or rq) private, and which ones are shared. From
Christoph.
- A set of patches from Bart, that improve how we handle queue
stopping and starting in blk-mq.
- Support for WRITE_ZEROES from Chaitanya.

With the current code it is possible to lock a mutex twice when
a subsequent reconnects are triggered. On the 1st reconnect we
reconnect sessions and tcons and then persistent file handles.
If the 2nd reconnect happens during the reconnecting of persistent
file handles then the following sequence of calls is observed:
cifs_reopen_file -> SMB2_open -> small_smb2_init -> smb2_reconnect
-> cifs_reopen_persistent_file_handles -> cifs_reopen_file (again!).
So, we are trying to acquire the same cfile->fh_mutex twice which
is wrong. Fix this by moving reconnecting of persistent handles to
the delayed work (smb2_reconnect_server) and submitting this work
every time we reconnect tcon in SMB2 commands handling codepath.
This can also lead to corruption of a temporary file list in
cifs_reopen_persistent_file_handles() because we can recursively
call this function twice.

The kernel client requests 2 credits for many operations even though
they only use 1 credit (presumably to build up a buffer of credit).
Some servers seem to give the client as much credit as is requested. In
this case, the amount of credit the client has continues increasing to
the point where (server->credits * MAX_BUFFER_SIZE) overflows in
smb2_wait_mtu_credits().
Fix this by throttling the credit requests if an set limit is reached.
For async requests where the credit charge may be > 1, request as much
credit as what is charged.
The limit is chosen somewhat arbitrarily. The Windows client
defaults to 128 credits, the Windows server allows clients up to
512 credits (or 8192 for Windows 2016), and the NetApp server
(and at least one other) does not limit clients at all.
Choose a high enough value such that the client shouldn't limit
performance.
This behavior was seen with a NetApp filer (NetApp Release 9.0RC2).
