rule_added_policy allows the modification of rules just after they have
been added. This allows the implementation of some more complex features
- like changing rule states depending on insertion in other plugins.
This field isn't required by a worker and it's certainly not used by a
worker to listen on that specific interface. It also isn't required to
be set consistently and its use in-tree limited to the old load-balancing
script.
There's a bif called packet_source() which on a worker will provide
information about the actually used packet source.
Relates to zeek/zeek#2877.
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
- 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.
These are no longer loaded by default due to the performance impact they
cause simply by being loaded (they have event handlers for commonly
generated events) and they aren't generally useful enough to justify it.
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
Mostly trying to standardize the way tests sleep for arbitrary amounts
of time to make it easier to tell at which particular point the
unit test actually may need the timeout interval increased (or else
debugged further).
The catch-and-release.bro test was failing whenever three conditions
were all true: sorting the netcontrol.log before comparing to
the baseline, the presence of LC_ALL=C in btest.cfg changes the sort
order, and sometimes the timestamp increases slightly beginning
with one of the rule_id == 5 lines.
As a result of these three conditions, the sorted order of the lines
with rule_id of 5 were different than the baseline.
Fixed by not sorting netcontrol.log, as this doesn't seem necessary.
This adds the capability for the user to attach a reason when removing
or destroying a rule. The message will both be logged in netcontrol.log
and forwarded to the responsible plugins.
Addresses BIT-1655
This adds an event that is raised once Catch & Release ceases the
block management for an IP address because the IP has not been seen in
traffic during the watch interval.
This allows users who use their own logic on the top of catch and
release know when they will have to start re-blocking the IP if it
occurs in traffic again.
forgotten messages are only logged on the manager (or standalone host)
now. Logs are not written by default anymore when Bro encounters traffic
that should have been blocked.
This commit rewrites catch and release, fixing issues with it and making
it fully cluster capable. A dedicated netcontrol_catch_release.log is
also added.
This is not quite done yet; a few more log messages are missing. There
should hopefully not be many big issues left.
This introduces two new events, NetControl::rule_new and
NetControl::rule_destroyed, which are raised when rules are first added
and then deleted from the internal state tracking.
When Bro was compiled with broker disabled, then some Bro scripts
were referencing functions and types that were not defined. Fixed
by adding @ifdefs to several scripts. Removed one @ifdef because
it was causing several unit tests to fail.
Also fixed the @TEST-REQUIRES check in tests that rely on broker so
that such tests are skipped when broker is disabled.
Also renamed the "print" function to "send_print" and the "event"
function to "send_event" because Bro shows a syntax error when a
Bro script function is named "event" or "print".
