[PATCH 00/16] Get SMB2 mount work

[Pavel Shilovsky]

This is the first SMB2 code specific patchset that enables experimental
SMB2 support for cifs module. This patchset lets mount/stat work
on SMB2 shares.

Also, it doesn't follow the "transport ops" approach we discussed with
Jeff Layton recently in the list but this part can be easily modified
further without big code changes.

The reason why I am posting it in this way is due to the fact that
I have already given much testing for this variant of the patchset
and don't want to change things before the release.

I rebased this on top of Jeff's cifs-3.4 branch.

Pavel Shilovsky (13):
  CIFS: Check for SMB2 vs CIFS in find_tcp_session
  CIFS: Add SMB2 status codes
  CIFS: Make transport routines work with SMB2
  CIFS: Add SMB2 credits support
  CIFS: Make demultiplex_thread work with SMB2 code
  CIFS: Respect SMB2 max hdr size for cifs_request kmem_cache
  CIFS: Add capability to send SMB2 negotiate message
  CIFS: Add session setup/logoff capability for SMB2
  CIFS: Add tree connect/disconnect capability for SMB2
  CIFS: Process reconnects for SMB2 shares
  CIFS: Add SMB2 support for is_path_accessible
  CIFS: Query SMB2 inode info
  CIFS: Get SMB2 mount work

Steve French (3):
  CIFS: Introduce SMB2 Kconfig option
  CIFS: Introduce SMB2 mounts as vers=2
  CIFS: Map SMB2 status codes to POSIX errors

[PATCH 01/16] CIFS: Introduce SMB2 Kconfig option

[Pavel Shilovsky]

From: Steve French <sfrench-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>

SMB2 is the followon to the CIFS (and SMB) protocols
and the default for Windows since Windows Vista, and also
now implemented by various non-Windows servers. SMB2
is more secure, has various performance advantages, including
larger i/o sizes, flow control, better caching model and more.
SMB2 also resolves some scalability limits in the CIFS
protocol and adds many new features while being much
simpler (only a few dozen commands instead of hundreds)
and since the protocol is clearer it is also more consistently
implemented across servers and thus easier to optimize.

After much discussion with Jeff Layton, Jeremy Allison
and others at Connectathon, we decided to move the SMB2
code from a distinct .ko and fstype into distinct
C files that optionally build in cifs.ko. As a result
the Kconfig gets simpler.

To avoid destabilizing CIFS, the SMB2 code is going
to be moved into its own experimental CONFIG_CIFS_SMB2 ifdef
as it is merged and rereviewed. The changes to stable
CIFS (builds with the SMB2 ifdef off) are expected to be
fairly small.

[PATCH 02/16] CIFS: Introduce SMB2 mounts as vers=2

[Pavel Shilovsky]

From: Steve French <sfrench-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>

As with Linux nfs client, which uses "nfsvers=" or "vers=" to
indicate which protocol to use for mount, specifying

"vers=smb2" or "vers=2"

will force an SMB2 mount. When vers is not specified CIFS is used

ie "vers=cifs" or "vers=1"

We can eventually autonegotiate down from SMB2 to CIFS
when SMB2 is stable enough to make it the default, but this
is for the future.  At that time we could also implement a
"maxprotocol" mount option as smbclient and Samba have today,
but that would be premature until SMB2 is stable.

Intially the SMB2 Kconfig option will depend on "BROKEN"
until the merge is complete, and then be "EXPERIMENTAL"
When it is no longer experimental we can consider changing
the default protocol to attempt first.

Now that we have a new SMB major version to deal with, a boolean really
seems unsuited to this purpose. Should we change this to be an unsigned
int or something and assign the correct version number to it?

I think we should not try to accept ver=smb2 or anything. Let's stick
with numbered versions. In fact, the ver=cifs that the current code
allows should also be removed, IMO. Nothing sends that now, and we
shouldn't establish the precedent.

Carrying this thought a bit further, I think we need to step back and
consider what this should look like from a user's standpoint:

After all, what does "ver=2" mean over the long-term? 2.002? 2.100?

Perhaps we should not accept "ver=2" and require an explicit "ver=2.0"
or "ver=2.1"? Ditto with 3.0?

Again, booleans for this seem like a less than ideal solution. Better
to have this based on a version number or maybe a protocol version enum?

Why is it more important to use TCP_NODELAY for SMB2? The above comment
doesn't really say...

The above should instead set a pointer to a "struct
protocol_operations" or something. That struct could have a version
field within it and it would give you a mechanism to allow for
protocol-version specific behavior without resorting to sprinkling
"is_smb2" checks all over the code.

On the tcp-nodelay question:

I think it complicates things to give the user a choice now (it should
be faster to send with nodelay) - should probably be unconditional
(less options for SMB2 is easier since we have a spec, and well
behaved servers)

On the "is_smb2" - mostly it just matters whether it is smb2 - but I
have no problem with a sub-version within smb2, but lets limit this as
much as is reasonably possible now (most servers support cifs - so
lets focus as narrowly as we can to accelerate development safely) I
really don't want to worry about testing smb2.0 vs. 2.1 vs. 2.2 (aka3)
- can't we simply offer smb2.1 and smb3 (if they need to talk to
Windows Vista they can use cifs) and choose between smb2.1 and smb3
via a sub-version field (remember these are MUCH easier in smb2 since
they are just a number not a string).

It is more complicated to give a choice, but why should we choose to
use TCP_NODELAY at all? Do we have any benchmarks or anything that show
that it really helps performance or makes any difference at all?

My point on the "is_smb2" mechanism is that you're enshrining a boolean
decision into code that will need more subtle decision making later.

Eventually we want to support at least one flavor of smb2 as well as
smb3. At that point, your boolean checks above become a real mess.

Really, it just comes down to planning ahead for support for other
dialects. Since we're restructuring the code now, let's do it in such a
way that we can add support for later dialects with less hassle in the
future.

We did have benchmarks that showed it was faster (it got requests
on the wire faster) but that was years ago.  Generally for request/response
protocols why wouldn't you always set TCP_NODELAY?

Because it's less efficient to send a request in two frames than one?
You're basically trading extra bandwidth for lowered latency. That's
not necessarily a win...

Consider a write request, for instance. If we have to do it in small
pieces we could end up sending more TCP frames than necessary which
have their own overhead. The data may get to the server faster in some
cases, but until the whole request is there it can't really do anything
with it anyway. You're better off having waited until it was all
buffered up.

I don't know one way or the other whether using TCP_NODELAY is faster
on some workloads. Before we make any assumptions however, we ought to
come up with a way to test that theory, and to assess its impact on
bandwidth utilization.

Re: [PATCH 03/16] CIFS: Check for SMB2 vs CIFS in find_tcp_session

[Steve French]

It is going to be a small effect normally but should be measurable -
for all smb requests
but write we issue them as one tcp send, and in all cases except write they
are small so can get delayed.

I remember asking Linux networking guys many years ago and they said
we should be setting it (unless something strange changed not sure
why the logic for all but writes would be different on no delay).

I don't see where the Linux NFS client sets TCP_NODELAY. I've also
never noticed the client delaying small requests, but I haven't really
looked for it either...
 
You may be correct here and it is beneficial, but I think we ought to
have some way to measure that gain and the impact on the overall
bandwidth utilization. After all, you don't get any speedup from this
"for free". It costs you in overall network utilization. That cost may
be marginal, but it won't be zero.

Steve had some confusion about the above statement, so I've hacked out
a small patchset to demonstrate what I'm been talking about. It's in
the "smb2-ops" branch of my git tree if you'd like to take a look.

http://git.samba.org/?p=jlayton/linux.git;a=shortlog;h=refs/heads/smb2-ops

The basic idea is to declare a smb_version_operations struct for each
ver= option that we want to support, and then set a pointer to that in
the TCP_Server_Info. We'll then have fields in there that are smb
version specific. Some might be populated in every one (like the
version_string field). Others not, (like the send_cancel function). In
the cases where they're not, the caller will need to deal with it.

In any case, this allows us to add SMB2 support without sprinkling
"is_smb2" checks all over the place, and more importantly gets rid of
the #ifdefs inside most of the code too. Whereever you have a "is_smb2"
check wrapped inside an ifdef now, you'd add a new ops vector to this
struct and populate it accordingly.

Thoughts?

If these are truly SMB2-specific error codes, shouldn't we prefix them
with something like SMB2_ ? What if SMB3 or 4 adds a new set?

There are collisions here between the codes already defined in nterr.h.
For instance, STATUS_BUFFER_OVERFLOW. Luckily that one seems to have
the same value in both places, but it's rather messy to have it defined
twice.

[PATCH 06/16] CIFS: Make transport routines work with SMB2

[Pavel Shilovsky]

that lets us send SMB2 negotiate message to the server further.

[Pavel Shilovsky]

[Pavel Shilovsky]

From: Pavel Shilovsky <piastryyy-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Now we can process SMB2 messages: check message, get message id
and wakeup awaiting routines.

Signed-off-by: Pavel Shilovsky <piastryyy-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
