public class ConnectionHandler
extends java.lang.Object

Receive new connection attempts Use a bounded queue to limit the damage from SYN floods, router overload, or a slow client

zzz modded to use concurrent and bound queue size

Constructor Summary

ConnectionHandler(I2PAppContext context, ConnectionManager mgr)
Creates a new instance of ConnectionHandler

Method Summary

Connection	accept(long timeoutMs) Receive an incoming connection (built from a received SYN) Non-SYN packets with a zero SendStreamID may also be queued here so that they don't get thrown away while the SYN packet before it is queued.
boolean	getActive()

ConnectionHandler

public ConnectionHandler(I2PAppContext context,
                         ConnectionManager mgr)

Creates a new instance of ConnectionHandler

Method Detail

setActive

public void setActive(boolean active)

getActive

public boolean getActive()

receiveNewSyn

public void receiveNewSyn(Packet packet)

Non-SYN packets with a zero SendStreamID may also be queued here so that they don't get thrown away while the SYN packet before it is queued. Additional overload protection may be required here... We don't have a 3-way handshake, so the SYN fully opens a connection. Does that make us more or less vulnerable to SYN flooding?

accept

public Connection accept(long timeoutMs)

Receive an incoming connection (built from a received SYN) Non-SYN packets with a zero SendStreamID may also be queued here so that they don't get thrown away while the SYN packet before it is queued.

Parameters:

timeoutMs - max amount of time to wait for a connection (if less than 1ms, wait indefinitely)

Returns:

connection received, or null if there was a timeout or the handler was shut down
