Hi, If we in the UDP/TCP/(SCTP?) dissectors saved next dissector on the first pas in say per packet data we could avoid repeated calls to heuristic dissectors and port/conversation lookups making the second pas faster. Does any one see any pitfalls with this idea? I can think of two ways of implementing it: - A new entry in pinfo "previous protocol" or something like that. or - make dissector_try_uint(), dissector_try_heuristic(), try_conversation_dissector() return the protocol or NULL; The second is perhaps cleaner but requires more changes or we could make new functions dissector_try_heuristic_ret_proto() etc or something like that. Comments?
SCTP might have multiple "next dissectors", one for each data chunk... Best regards Michael
