Hi
looks very good.
One thing.
Where you use : if (ntlmssp_tree) { in
dissect_dcerpc_ntlmssp_negotiate_flags()
currently this if statement encapsulates everything, including the
proto_tree_add_boolean() calls.
Change this so the if statement only encaspulates the tf= and
negotiate_flags_tree= statements
and leave the proto_tree_add_boolean()s outside the if statement.
If you dont do this, display filters searching for specific flag values will
not work.
(The if statement is only a microoptimization to get rid of one
proto_tree_add_xxx() and one
proto_item_add_subtree() for the cases when we dont need a tree since we
only decode the packet
in order to match it with a display filter)
For the same reason, getting displayfilters to work, you should get rid of
the other if(ntlmssp_tree) ifstatements
and get it to do the proto_tree_add_item() for workstation/domain
unconditionally.
