* Handle TCP reset sequence properly.ru1999-09-091-2/+2
| | | | | | | | | | | | | | | | | | | In the words of originator: :If an incoming connection is initiated through natd and deny_incoming is :not set, then a new alias_link structure is created to handle the link. :If there is nothing listening for the incoming connection, then the kernel :responds with a RST for the connection. However, this is not processed :correctly in libalias/alias.c:TcpMonitor{In,Out} and :libalias/alias_db.c:SetState{In,Out} as it thinks a connection :has been established and therefore applies a timeout of 86400 seconds :to the link. : :If many of these half-connections are initiated (during, for example, a :port scan of the host), then many thousands of unnecessary links are :created and the resident size of natd balloons to 20MB or more.

| | | | | | | | | Add bounds checking to netbios NS packet resolving code. This should prevent natd from crashing on badly formed netbios packets (as might be heard when the machine is sitting on a cable modem or certain DSL networks), and also closes potential security holes that might have exploited the lack of bounds checking in the previous version of the code.
