All-

 

I have developed many dissectors, but have not run up against this
problem before. I am looking for a solution that will work inside a
plugin dissector.

 

The issue is that I have some secure traffic that I cannot decode until
I learn some state that is only periodically advertised. This means that
during the first pass through the packets that I will fail to decode
many packets, but that by the end of the first pass I will have (likely)
learned enough to decode the previous packets.

 

I believe (and will shortly test) that any secondary decodes (as
clicking on the undecoded packet) will magically cause the column info
to update and the packet to display decoded (assuming that my learned
state is associated with my conversation, which it is).

 

My question is whether it is possible to indicate to Wireshark that
certain packets (or, worst case, all packets) should be rechecked. If it
is only the "all packets" case I would likely not do anything (as I deal
with large capture files). If selected packets could be redone then that
might be interesting, as I know which packets are "mine" and if I learn
later that I can decode them then I would know the frame numbers to
re-parse.

 

Thoughts? Thanks.
