Wireshark · Wireshark-dev: [Wireshark-dev] How to register a dissector for a specific traffic type?

[Yves Geissbühler <geyves@xxxxxxx>]

Hi all

I have several protocols running on top of each other: TCP > MPA (RFC  
5044) > [DDP (RFC 5042) | RDMAP (RFC 5040)].

Currently, I am calling my DDP/RDMAP dissector as a subdissector from  
my MPA dissector. Because my DDP/RDMAP dissector could also be used  
on top of SCTP (replacing TCP and MPA) calling it as a subdissector  
from my MPA dissector does not seem to be the right solution anymore.  
It would make more sense if my DDP/RDMAP dissector would get called  
whenever there is MPA or SCTP traffic. So I would like to register my  
DDP/RDMAP dissector for these to types of traffic.

So far I could not figure out how to achieve this.

In which manner do I have to return (in the proto_reg_handoff_mpa()?)  
from my MPA dissector such that a call to heur_dissector_add("mpa",  
dissect_ddp_rdmap, proto_ddp_rdmap) in my DDP/RDMAP dissector would  
work?


Thanks.
