man 7 tcp says TCP_LINGER2 sets the lifetime of orphaned FIN_WAIT2 state
sockets.  What about wanting to forcibly kill a "rotten" TCP socket in
any other "WAIT" state like TIME_WAIT?

Thanks.

Reza.

The whole point of TIME-WAIT is catching old packets still in network.
Killing it early would avoid its purpose.

tcp_max_tw_buckets does exactly that system wide, and for good reason. 
Why not give userspace oversight over the process?
