This switches the DPD logic to always log analyzers that raised a
protocol confirmation.
The logic is that, once a protocol has been confirmed - and thus there
probably is log output - it does not make sense to later remove it from
the log. It does make sense to somehow flag it as failed - but that
seems like a secondary step.
Introduce two new events for analyzer confirmation and analyzer violation
reporting. The current analyzer_confirmation and analyzer_violation
events assume connection objects and analyzer ids are available which
is not always the case. We're already passing aid=0 for packet analyzers
and there's not currently a way to report violations from file analyzers
using analyzer_violation, for example.
These new events use an extensible Info record approach so that additional
(optional) information can be added later without changing the signature.
It would allow for per analyzer extensions to the info records to pass
analyzer specific info to script land. It's not clear that this would be
a good idea, however.
The previous analyzer_confirmation and analyzer_violation events
continue to exist, but are deprecated and will be removed with Zeek 6.1.
...the only known cases where the `-` for `connection$service` was
handled is to skip/ignore these analyzers.
Slight suspicion that join_string_set() should maybe become a bif
now determine_service() runs once for each connection.
Closes#2388
* Because frameworks/analyzer is loaded via init-frameworks-and-bifs the
dpd functionality (really just dpd.log and disabling of analyzers) is
now enabled even in bare mode.
* Not sure we need to keep frameworks/base/dpd/__load__.zeek around
or can just remove it right away.
