This has been a wrapper around server_event_context() for some time
now, and removing this from dummmysmbd.c assists with library
dependencies.

(I based it on the text in MS-SMB2, silly me :-). Fix it so incoming sequence numbers
can range over the entire allowable bitmap range. This fixes a repeatable
disconnect against Win7.

twice (ultimately perhaps because of bug 7331 involving this compound sequence and the need
to be ready for any incoming CANCEL of the NOTIFY). This had the server thinking it had
granted more credit than it actually had, which lead to zero-credits being granted in interim
NOTIFY responses.

This reorganizes smbd_smb2_request_dispatch to have a central exit point,
and use the normal profiling macros.

Based on code from Ira Cooper <samba@ira.wakeful.net>, and also
advice on refactoring the patch into a function call. outbuf vectors
can be reallocated by smb2 processing code, so when returning interim
responses we must not make assumptions about vector size.

A create call comes in, goes async (on the oplock request).
At a later time (just before a cancel request is received)
it completes, and goes through smbd_smb2_request_reply() to
send the reply to the create call.
However, the output socket queue is full, so when
tstream_writev_queue_send() is called from smbd_smb2_request_reply(),
the smb2req stays on the "being processed" queue on
sconn->smb2.requests, as only when tstream_writev_queue_send() completes
is smbd_smb2_request_writev_done() get called, which will TALLOC_FREE
the smb2req (and thus take if off the queue).
The cancel comes in, gets processed and looks through the
requests on the queue, and BANG - hits the smb2req that
has already been processed and is outgoing....
Remove the request from the queue once
tstream_writev_queue_send() is called and not in the talloc
destructor function.

It turns out that the persistent handles are used by the Microsoft
redirector to index files on oplock break requests. So even if we
don't do durable handles (yet) we must set the persistent handle
on create. For now just use the same handle value as we use for
volatile.
Jeremy.
Makes SMB2Create call re-entrant internally.
Now this infrastructure is in place, oplocks will follow shortly.
Tested with Win7 client and with W2K8R2.
Jeremy.
Don't free the cancelled SMB2 req early, let the cancelation
function take care of it. Return a NT_STATUS_CANCELLED when
we find and cancel a request. Fix our SMB2 error returns to
correctly set the structuresize to 9, and add the expected
zero byte (see section 2.2.2 in the SMB2 spec.).
This causes Samba to pass the test program in this bug report
that W2K8R2 fails (heh heh :-). This is because we always cause
compound requests to get to a cancelation point before dealing
with a cancel request.
Jeremy.
Gets us handling SMB2 compound async requests similar to W2K8R2
(and triggers the same client bug in the Win7 redirector). Great
thanks to Ira Cooper <samba@ira.wakeful.net> for helping with
this and to Metze for the wonderful async framework. The one
thing I need to fix to make us identical to W2K8R2 is that
when a compound request goes async at the end W2K8R2 splits
the replies up into a compound non-async reply followed by
a separate async reply. Currently we're doing the whole thing
in a compound reply.
Jeremy.
and then return to the client the number of credits per operation
that they asked for. This is a more sensible algorithm than just
blindly returning "20" on every reply, although we will probably
still need more changes to this going forward.
Jeremy.
