btest/net-control: Use different expiration times for rules
analyzer: Add analyzer.log for logging violations/confirmations
By default this only logs all the violations, regardless of the
confirmation state (for which there's still dpd.log). It includes
packet, protocol and file analyzers.
This uses options, change handlers and event groups for toggling
the functionality at runtime.
Closes#2031
In certain deployment scenarios, all analyzers are disabled by default.
However, conditionally/optionally loaded scripts may rely on analyzers
functioning and declare a request for them.
Add a global set set to the Analyzer module where external scripts can record
their requirement/request for a certain analyzer. Analyzers found in this
set are enabled at zeek_init() time.
This allows to enable/disable file analyzers through the same interfaces
as packet and protocol analyzers, specifically Analyzer::disable_analyzer
could be interesting.
This adds machinery to the packet_analysis manager for disabling
and enabling packet analyzers and implements two low-level bifs
to use it.
Extend Analyzer::enable_analyzer() and Analyzer::disable_analyzer()
to transparently work with packet analyzers, too. This also allows
to add packet analyzers to Analyzer::disabled_analyzers.
Now that it's loaded in bare mode, no need to load it explicitly.
The main thing that tests were relying on seems to be tracking of
c$service for conn.log baselines. Very few were actually checking
for dpd.log
This allows us to create an EnumType that groups all of the analyzer
tag values into a single type, while still having the existing types
that split them up. We can then use this for certain events that benefit
from taking all of the tag types at once.
- Use `-b` most everywhere, it will save time.
- Start some intel tests upon the input file being fully read instead of
at an arbitrary time.
- Improve termination condition for some sumstats/cluster tests.
- Filter uninteresting output from some supervisor tests.
- Test for `notice_policy.log` is no longer needed.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
I've used the opportunity to also cleanup DPD's expect_connection()
infrastructure, and renamed that bif to schedule_analyzer(), which
seems more appropiate. One can now also schedule more than one
analyzer per connection.
TODOs:
- "make install" is probably broken.
- Broxygen is probably broken for plugin-defined events.
- event groups are broken (do we want to keep them?)
- parallel btest is broken, but I'm not sure why ...
(tests all pass individually, but lots of error when running
in parallel; must be related to *.bif restructuring).

- Document API for src/analyzer/Analyzer.h
