2024-02-21R-GOOSE: Strengthen heuristic for CLTP on UDPJohn Thacker1-40/+0
Reduce false positives of the CLTP on UDP dissector (RFC 1240) by looking at the parameters as well and also ruling out length indicator zero. See https://ask.wireshark.org/question/31455/i-see-a-malformed-packet-in-wireshark-from-a-google-ip-address-on-port-2400-using-r-goose-protocol-what-could-this-be/ RFC 1240 was rendered Historic by RFC 2556, which noted that "at this time there do not seem to be any implementations" and recommended TPKT (ISO on TCP) instead. However, R-GOOSE does use RFC 1240. In practice, it seems like R-GOOSE uses the IANA registered port for ISO-TSAP, 102, just like TPKT does on TCP. Perhaps we should register the dissector to that port instead of a heuristic dissector if someone can confirm that. Move the dissector from goose to ositp. This doesn't cause any preference issues because heuristic dissectors are saved in the preference file by name and the name won't change.

Part 1/2 as the commits were too big for CI. Largely find/replace, with a few manual tweaks. Then regenerate the asn1 dissector sources and make sure everything still builds. There are a handful of cases I skipped as too complex, but this covers most of the asn1 dissectors.
2021-02-01GOOSE: New option to display float valuesAitor Garcia1-12/+31

2020-02-25goose: test field is renamed to simulationAlexis La Goutte1-4/+4
The GOOSE dissector included Wireshark is using the GOOSE message definition that was described in an older version of the IEC 61850 standard. To be precise, the current field names in Wireshark corresponds to the Edition 1 of the IEC 61850 standard. This GOOSE message definition is defined in Table 23 of the IEC 61850-7-2:2003. In this release (IEC 61850-7-2:2003) there is a field name called: Test. However, in the new version of the IEC 61850, the Edition 2 of the IEC 61850 standard, the Test field was renamed to Simulation. To be precise, the new GOOSE message definition is defined in Table 43 of the IEC 61850-7-2:2010.
