This patch introduces new APIs to allow dissectors to have a preference for a (TCP) port, but the underlying data is actually part of Decode As functionality. For now the APIs are intentionally separate from the regular APIs that register a dissector within a dissector table. It may be possible to eventually combine the two so that all dissectors that register with a dissector table have an opportunity to "automatically" have a preference to adjust the "table value" through the preferences dialog. The tcp.port dissector table was used as the guinea pig. This will eventually be expanded to other dissector tables as well (most notably UDP ports). Some dissectors that "shared" a TCP/UDP port preference were also converted. It also removed the need for some preference callback functions (mostly when the callback function was the proto_reg_handoff function) so there is cleanup around that. Dissectors that has a port preference whose default was 0 were switched to using the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference Also added comments for TCP ports used that aren't IANA registered.

/* OUCH is a stock exchange order entry protocol published and used by
|
|
* NASDAQ. This dissector supports versions 4.x, which differ from
|
|
* earlier versions by adopting binary encoding for numeric values.
|
|
*
|
|
* OUCH is usually encapsulated within NASDAQ's SoupBinTCP protocol,
|
|
* running over a TCP connection from the trading application to the
|
|
* exchange. SOUP provides framing, heartbeats and authentication;
|
|
* consequently none of these is present in OUCH.
|
|
*
|
|
* Other exchanges have created order entry protocols very similar to
|
|
* OUCH, but typically they differ in subtle ways (and continue to
|
|
* diverge as time progresses) so I have not attempted to dissect
|
|
* anything other than proper NASDAQ OUCH in this code.
|
|
*
|
|
* Specifications are available from NASDAQ's website, although the
|
|
* links to find them tend to move around over time. At the time of
|
|
* writing, the correct URL is:
|
|
*
|
|
* http://www.nasdaqtrader.com/content/technicalsupport/specifications/TradingProducts/OUCH4.2.pdf
