change the semantics of hosts allow/hosts deny so that a global

setting applies to all shares regardless of any settings on other
shares. This allows us to immediately drop a connection if it does not
come from a allowed host, without even parsing the first SMB
packet. The next time we get a nasty security hole we can offer people
the option of just setting their hosts allow line.

If we drop a connection in this way we generate a "Not listening for
calling name" response and then exit.


add a per share "oplocks" option in smb.conf. I think its important to
be able to disable oplocks on a per-share basis as there are occasions
then they are definately not wanted, for example when sharing data
between a windows box and a unix application. This also allows us to
tell people "try disabling oplocks" when diagnosing problems.


fix a bug in process_smb(). It was taking the length of the packet
from outbuf, not inbuf (this bug was introduced with the oplocks
code). Jeremy, I assume this wasn't deliberate?

 You can specify the hosts by name or IP number. For example, you could
