handling of the &os; TCP stack has been improved

|
|
The algorithm is as follows: For connections in the

<literal>ESTABLISHED</literal>

|
state, only resets with sequence numbers exactly matching
|
|
<varname>last_ack_sent</varname> will cause a reset;

all other segments will

be silently dropped. For connections in all other states,

|
a reset anywhere in the window will cause the connection
|
|
to be reset. All other segments will be silently dropped.
|
|
Note that this behavior technically violates the RFC 793 specification;
