2022-08-09prefs: More cleanup, auto prefsJohn Thacker1-20/+15
Remove callback function from pref registrations for dissectors that don't need a callback. In other dissectors, move registration that only needs to be done once inside the check for initialization, avoiding some console messages when preferences are changed ("Duplicate dissectors (anonymous) and (anonymous) for protocol...") and the like. Add a couple auto preferences for dissectors missed in previous waves. Ping #14319

2019-06-10cisco-fp-mim: Adding FabricPath FCS dissection and verificationAlexander Koeppe1-10/+53
FabricPath recalculates the FCS based on the whole packet (incl. the Ethernet header) and overwrites the last four bytes of the packet, effectively stealing the Ethernet FCS. Since FabricPath FCS dissection and verification isn't available and falsely attempted on the Ethernet layer, this commit implements the FCS treatment on the FabricPath layer and treats the Ethernet layer explicitely as it would not have a FCS. It also adds a procotol option to enable FabricPath FCS validation which is disabled by default though.

2019-05-28cisco-fp-mim: Properly handle FabricPath header variations (.1Q VLAN)Alexander Koeppe1-110/+118
Under some circumstances, FabricPath frames may be generated during a monitor (capture) session, that contains a modified FabricPath header format in order to retain the ID of the original FabricPath VLAN. To make wireshark capable to dissect such frames, this commit amends the heuristic logic of the dissector and make it work as a heuristic-only dissector Change-Id: I40f6f75a629585ececbc1ce4f94fa61065110d2c Reviewed-on: https://code.wireshark.org/review/33321 Petri-Dish: Anders Broman <a.broman58@gmail.com> Tested-by: Petri Dish Buildbot Reviewed-by: Anders Broman <a.broman58@gmail.com>

2016-03-20Manually add protocol dependencies derived from find_dissector.Michael Mann1-1/+1
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.

2016-01-20Separate "Ethernet in capture file" and "Ethernet maybe with FCS" dissectors.Guy Harris1-7/+4
Have a dissector that is passed a "struct eth_phdr" pointer, indicating whether there is an FCS, there is no FCS, or there's maybe an FCS, and an "eth_maybefcs" dissector, to be called from other dissectors. The latter takes no data argument. That obviates the need for callers of the latter to fill in an "eth_phdr" structure. Note in a comment that setting the "assume an FCS" preference overrides a file format handler in Wiretap saying "we have no FCS". I seem to remember that this might be intentional.

2016-01-18Have the "maybe an FCS" version of the Ethernet dissector take a data argument.Guy Harris1-2/+8
It's called from some places other than packet-frame.c, at least one of which currently can't call anything else (the ATM dissector, for VC-multiplexed bridged frames, where you don't know whether the frames include the FCS or not), so the frame's pseudo-data doesn't necessarily have the appropriate "FCS length" value. Have it explicitly check the data argument, and explicitly pass the appropriate value to it.
