[Wireshark-dev] Use of wireshark to interpret input data that does not depend on any other existing protocols
Hi All, I am adding a new protocol to wireshark that does not rely or depend on any other protocols(tcp, udp, ethernet,ppp,etc). I will be thankful if anyone can help me understand the following things: 1. I have written the protocol dissector for my unique protocol. But how do I differentiate the input packets in .pcap file so that only my protocol dissector gets called to process the data? And how can I add uniqueness to the input data stream to customize it to my protocol. Is the protocol identified by means of some common pattern in the input stream of bytes .If that is the case, how can I do that? 2. What is the difference between the dissector table and encapsulation table. I have understood how the protocol dissector encodes the input data and display it in a tree based on the formatting defined by static arrays ett and hf. What all steps I need to perform in order to write a protocol dissector that does not depend on any existing protocols and customize the input data in pcap file so that my protocol dissector gets called only when it comes across correct input data.

Thus wrote Mrunal Upadhyay (m.upadh...@sta.samsung.com): 1. I have written the protocol dissector for my unique protocol.

And how can I add uniqueness to the input data stream to customize it to my protocol. Is the protocol identified by means of some common pattern in the input stream of bytes .If that is the case, how can I do that? you have a data link type (DLT) in the .pcap file (http://www.tcpdump.org/linktypes.html) In wireshark, you map this DLT value to a WTAP_xxx value in pcap_to_wtap_map[]. In your dissector, you call dissector_add_uint() to register your dissector for your WTAP_xxx. And you should check all incoming data to make sure that it's actually your protocol. You can take the DVB-CI dissector (any many others) as an example. ___ 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-requ...@wireshark.org?subject=unsubscribe

Have you tried to disable packet-parlay to check whether it is the only dissector creating such an issue? It takes about 2GB or more of memory in the static analyzer to analyze dissect_parlay(); is the static analyzer built 64-bit or 32-bit, or is it running out of swap space+memory? Perhaps if the CORBA-IDL-to-Wireshark-dissector tool didn't generate 3MB of source code, this would be less of a problem.

You have no need for a proto_item_add_subtree without using the return value. In this case I suppose flags1_tree should be use in the next dissect_dcerpc_uint8 calls instead of using flags1_item.

Hmm, after a closer look I find that proto_item_add_subtree() returns the input parameter, so we have no real bug here. But this raises a question why we have to use the return value from proto_item_add_subtree() for the tree, as proto_item and proto_tree are the same... I think the cleanest solution is to use the return value, as this is done elsewhere and the implementation of proto_item_add_subtree() may change.

To be sure you have the right sources, you might want to check the file signature against the one posted at http://www.wireshark.org/download/src/all-versions/. You might also try switching to 1.4.6 now that it's been released.
