Rather than allow the "Katamari" (as Guy once fittingly referred to pinfo as) to grow even more by my earlier quick suggestion of adding a field to indicate the number of bytes consumed by the sub-dissector, might there instead be some value in adding some new-style dissector_try_port/heuristic() functions that return the number of bytes dissected rather than simply TRUE or FALSE?
Unfortunately, as I discovered when investigating having dissectors return number of bytes dissected *and* have that be an accepted/rejected indication, there are some cases where a dissector dissects zero bytes of packet data *but* accepts the packet. I'd have to dig a bit to remember when that happened. It might not matter with heuristic dissectors. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
