2014-12-11Add a heur_dissector_table_foreach() function.Guy Harris1-0/+14
This is, for heuristic dissector tables, the equivalent of dissector_table_foreach() for keyed dissector tables. Change-Id: I4b2f870e1c1179fda1adddd93930b83aaaaf8763 Reviewed-on: https://code.wireshark.org/review/5715 Reviewed-by: Guy Harris <guy@alum.mit.edu>

2014-05-24Allow wtap_read() and wtap_seek_read() to return records other than packets.Guy Harris1-2/+2
Add a "record type" field to "struct wtap_pkthdr"; currently, it can be REC_TYPE_PACKET, for a record containing a packet, or REC_TYPE_FILE_TYPE_SPECIFIC, for records containing file-type-specific data. Modify code that reads packets to be able to handle non-packet records, even if that just means ignoring them. Rename some routines to indicate that they handle more than just packets. We don't yet have any libwiretap code that supplies records other than REC_TYPE_PACKET or that supporting writing records other than REC_TYPE_PACKET, or any code to support plugins for handling REC_TYPE_FILE_TYPE_SPECIFIC records; this is just the first step for bug 8590.

2014-03-14Add Lua heuristic dissector supportHadriel Kaplan1-1/+5
This adds the ability for Lua scripts to register heuristic dissectors for any protocol that has registered a heuristic dissector list, such as UDP, TCP, and ~50 others. The Lua function can also establish a conversation tied to its Proto dissector, to avoid having to check the heuristics for the same flow. The example dissector in the testsuite has also been enhanced to include a heuristic dissector, to verify the functionality and provide an example implementation.

2014-01-30Add remove_last_data_source and fix bug 9169Evan Huus1-0/+2
The OP asked 9169 to be reopened because the capture was spewing ~40GB of output when dissected with tshark. Investigation showed this was because the HTTP dissector was requesting ONE_MORE_PACKET reassembly a lot, and TCP was adding each step as a data-source which was being printed by tshark's hex dump. This was leading to O(n^2) of output. To fix, introduce function remove_last_data_source which removes the most recent data source from the list. If the subdissector in TCP reassembly asks for ONE_MORE_PACKET, assume it hasn't added any tree items (since it shouldn't have) and remove the data source since it is unnecessary. This may break dissectors which add tree items and *then* return ONE_MORE_PACKET, since they will have their data source removed out from under them. I believe those cases should be fixed to not add tree items until they're sure they have enough data.

(https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9607) This is a VERY PRELIMINARY version of tfshark. It's an attempt to jumpstart FileShark and its architecture. Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it) This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture. And those layers will slowly be added in time (patches always welcome!). svn path=/trunk/; revision=54646

from the GTK flavor in two major ways: - The "Decode As" and "User Specified Decodes" dialog have been unified. - You can modify the decode as behavior at any time, not just when you have a packet selected. Revert part of 53498 so that we can move items marked /*** THE FOLLOWING SHOULD NOT BE USED BY ANY DISSECTORS!!! ***/ from epan/decode_as.h to ui/decode_as_utils.h. Move "save" code from decode_as_dlg.c to decode_as_utils.c as well. In packet-dcerpc.c don't register a table named "ethertype". We might want to add checks for duplicate table names. To do: - Add support for ranges? - Either add support for DCERPC or make DCERPC use a regular dissector table. - Fix string selectors (i.e. BER). svn path=/trunk/; revision=53910

(https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9454) The main driving force for this was my new Decode As functionality (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9450) that wants a dissector/subdissector table relationship for all dissectors wanting to use Decode As functionality. The ethertype() function provides the value to the "ethertype" subdissector table, so I think it should be matched to a dissector. Only odd side effect is the display filter of "ethertype" returns no packets because there is no "item" associated with the dissector. svn path=/trunk/; revision=53443
