2017-01-10Rename tvb_new_subset() to tvb_new_subset_length_caplen().Guy Harris1-1/+1
This emphasizes that there is no such thing as *the* routine to construct a subset tvbuff; you need to choose one of tvb_new_subset_remaining() (if you want a new tvbuff that contains everything past a certain point in an existing tvbuff), tvb_new_subset_length() (if you want a subset that contains everything past a certain point, for some number of bytes, in an existing tvbuff), and tvb_new_subset_length_caplen() (for all other cases). Many of the calls to tvb_new_subset_length_caplen() should really be calling one of the other routines; that's the next step. (This also makes it easier to find the calls that need fixing.)

2016-10-08Combine Decode As and port preferences for tcp.port dissector table.Michael Mann1-31/+7
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.

2016-03-20Manually add protocol dependencies derived from find_dissector.Michael Mann1-2/+2
Started by grepping call_dissector_with_data, call_dissector_only and call_dissector and traced the handles passed into them to a find_dissector within the dissector. Then replaced find_dissector with find_dissector_add_dependency and added the protocol id from the dissector. "data" dissector was not considered to be a dependency.

2015-07-17Remove all preferences related to enabling/disabling heuristic dissectors.Michael Mann1-1/+1
The preferences are still supported for backwards compatibility, but the heuristic_protos file has final say on the "preference" to enable/disable a heuristic dissector. Also add parameter to heur_dissector_add() for the "default" enable/disable of a heuristic dissector. With this parameter, a few more (presumably weak) heuristic dissectors have been "registered" but of course default to being disabled.

the heuristics of NDMP require 28 bytes to be present in order for it to be dissected as NDMP. NDMP is purely a heuristic dissector because TCPENCAP shares the same TCP port. Since NDMP officially registered port 10000 with IANA, allow it to use dissector_add_uint() instead of packet-ipsec-tcp.c, and by default have TCPENCAP only rely on its heuristics. https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5462 svn path=/trunk/; revision=51180
