Wireshark · Ethereal-dev: Re: [Ethereal-dev] RTP analysis. Same SSRC for several streams causes problems

["Ronnie Sahlberg" <ronnie_sahlberg@xxxxxxxxxxxxxx>]

I have checked in a small patch to make the tap listener only be called for
thos RTP packets that
match the udp conversation.

It should make it less likely to trigger the bug.

Ofcourse, if the same SSRC value is choosen for both directions, we are
still stuffed.

I also fixed the ICMP bug by just telling the RTP tap that it doesnt want to
listen to any packets
containing icmp

Subject: [Ethereal-dev] RTP analysis. Same SSRC for several streams causes
problems


Hi,

I got some strange result when using RTP Analysis on one capture file with
several different RTP streams
between different ip-addresses. The RTP Analysis complained about wrong
sequence numbers.
When I looked closer I noticed that when there are more than one RTP streams
using the same SSRC value then the RTP Analysis will handle all RTP packets
with that SSRC value as belonging to the same RTP stream.
I think that there should be a check not just for SSRC value but also source
address, destination address, source
port number and destination port number to identify what packets are
belonging to the same stream.
