Re: [ns] udp agent bug ? and patch

["Sergio Andreozzi" <sergio.andreozzi@lut.fi>]

Hi Alexander,

I was wondering why a so relevant bug has been never discovered (e.g. it
affects all statistics about bandwidth). Moreover my trace files about UDP
always were correct.

At a first look is obviuos bug, but looking more carefully I found as
follow:

1. in UdpAgent::sendmsg
		p = allocpkt();

this instruction call allocpkt() defined in agent.h/cc,

2. in Agent::allocpkt
		initpkt(p);

3. in Agent::initpkt
		ch->size() = size_;

size_ is defined in agent.h and UdpAgent inherits it.

So it seems there is no bug.


Bye,

	Sergio
