Suricata

Recently our networking analysts found out that dcerpc.opnum and it's sibling dce_opnum don't support operators >,<,!,=

Suricata prints the error "Error parsing dce_opnum option in signature" while parsing rule:

alert tcp any any -> any any (msg:"CVE-2024-38073"; sid:200; rev:1; flow:to_server,established; dcerpc.opnum:>1;)

The rule might be easily replaced by:

alert tcp any any -> any any (msg:"CVE-2024-38073"; sid:200; rev:1; flow:to_server,established; dcerpc.opnum:2-65535;)

It seems the keyword is important and if it's a real problem then a Redmine ticket could be found but I didn't find anything related to it.
I think it's the documentation issue.

All operators might be easily replaced by precise numbers and/or ranges.

I checked also the implementation and I see the functionality was never present.
