Would like to have a clarification in MS-SMB2 document about the
1) Types of error a server can return in response to a session logoff
request from a client (section 2.2.8).
2) The state of the session and expected client behaviour when a server
returns an error to a session logoff request.
Specifically, does the client behaviour stated in section 18.104.22.168
(Receiving an SMB2 LOGOFF Response) apply in case of an error as well?
3) There is no verbiage about server behaviour if the signature verification
fails the way it is described for client behaviour if the signature
verification fails in section 22.214.171.124.3.
In the context of session logoff request, if the signature does not match,
what is the correct/expected server behaviour?
Right now, in SMB3 dialect, Windows 8 server returns a response with an
error (access denied) for a missing/mismatched signature. Is that correct
or should a server discard the request and do no further processing for it?
MS-CIFS document lists the types of error a server may return in response
to a session logoff request (section 126.96.36.199.2) but it does not state the
state of the smb session and expected client behaviour in case of
an error received in logoff response in section 188.8.131.52.
In case of signature mismatch in the context of session logoff request,
Windows 8 server for smb1 dialect, behaves in a similar way as above (smb3).
