a796542a93 Implement oplocks within SMB2. Plumb into the existing SMB1 oplock system. 
Seems to work but needs more tests (to be added).

247273196f When sending the initial async response, this is never part of a chain. 
Get the reply flags correct.

8f67f873ac Make deferred opens (NT_STATUS_SHARING_VIOLATION) work over SMB2. 
Makes SMB2Create call re-entrant internally.
Now this infrastructure is in place, oplocks will follow shortly.
Tested with Win7 client and with W2K8R2.

60d3692918 Now SMB2 error messages are correctly being returned with the 1 byte data area, smbd_smb2_request_error_ex() must call smbd_smb2_request_done_ex() in order to do the padding correctly on compound replies.

8bf7942fa4 Ensure vectors are always allocated with consistent size. Removes one byte alloc on SMB2 error packet. Always use talloc_zero_array on out vectors - fixes valgrind errors in tevent writes.

59fa1e1890 Final fix for #7331 - Compound async SMB 2 requests don't work right. 
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.

1aa80f5788 Second part of fix for bug #7331 - Compound async SMB 2 requests don't work right. 
Cause us to match W2K8R2 by sending an interim compound reply
followed by a async reply.

bf45b4f4fd First part of fix for bug #7331 - Compound async SMB 2 requests don't work right. 
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.

6800fdbb81 Make smbd_lock_socket/smbd_unlock_socket recursive with a ref_count. 
As these always call exit_server, make that part of the function.
Use _internal functions for the echo client.

Metze please check !

26891651ec Change the credential handling so that we start with maxmux creds, 
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.

12ed9ca36a s3:smbd: fix parsing of invalid SMB2 requests. 
Because of 0 - 2 => 0xFFFFFFFE, we got EMSGSIZE
from the tstream layer. And terminate the transport
connection. Instead we should let the caller deal with
the invalid parameter, when checking the body size.
So the caller always gets at least a 2 byte body.
