This prepares the move where ConnKey implementations should fill out
ctx rather than filling conn_id directly. The API continues to receive
both, conn_id and ctx, as adding fields to `conn_id` is reasonable
use-case even if it's just for logging purposes.
This nested record can be used to discriminate orig_h or resp_h being
observed in different "contexts". A context can be based on VLAN tags,
but any custom ConnKey implementation should populate the ctx field,
allowing to write context-aware Zeek scripts without needing to know
what the context really is.
Changes in endpoint stats are a side-effect caused by the ConnSize
analyzer updating the conn record triggering the threshold event. The
phenomenon is described in https://github.com/zeek/zeek/issues/4214.
Closes#4504
Messages are not typical responses, so they need special handling. This
is different between RESP2 and 3, so this is the first instance where
the script layer needs to tell the difference.
A bit ad-hoc formatting for the log, but that's mostly because cluster.log
only has message field and I don't think having a dedicated application_name
column is worth it. That could also be added by custom scripts if it's really
wanted for a given deployment.

The Spicy based SSL analyzer was, so far, more permissive with the
record layer versions that it would accept.
This change brings the parsing of record layer versions in line with the
binpac based analyzer. This behavioral difference was discovered due to
a test that changed with the recent dpd log changes.

One bug fix removing static from a variable that shouldn't be static.
Using a label named "endpoint" is not intuitive and requires explaining to
users that it's really just the Cluster::node value. Change the label to
"node", so that we don't need to do the explaining.
This probably breaks some existing users of the Prometheus metrics, but after
looking more at metrics recently, "endpoint" really is a thorn in my eye.
This commit fixes the parsing of the data field in the SSL analyzer. So
far, this field contained two extra bytes at the beginning, which
contain the length of the following data.
Now, the data passed to the event only contains the actual value of the
session ticket.
The Spicy analyzer already contains the correct handling of this field,
and does not need to be updated. A test that uses the event and
exhibited the bug was added.

ZeroMQ's IPv6 support isn't enabled by default, resulting in
"No such device" errors when attempting to listen on an IPv6
address. This change adds a ipv6 option to the ZeroMQ module
and enables it by default. Further, adds a test configuring
everything to listen on IPv6 ::1 as well, and one test to provoke
the original error. This also regularizes some error messages.
The addr_to_uri() calls weren't actually needed, but they apparently do
not hurt and the result is easier on the eyes, so use them :-)
* origin/topic/johanna/default-canonifier-only-first-timestamp:
Default canonifier change to only remove first timestamp in line
Align SMB timestamp calculation between operating systems
The schema of cluster WebSocket error messages deviated from the
existing one in Broker which breaks seamless migration from the Broker
WebSocket bindings.
This patch aligns the serialization in cluster with the one in Broker.
This is technically a breaking change of the cluster schema, but since
it never worked like documented and is still experimental this is
probably fine.
Closes#4594.
In the past, we used a default canonifier, which removes everything that
looks like a timestamp from log files. The goal of this is to prevent
logs from changing, e.g., due to local system times ending up in log
files.
This, however, also has the side-effect of removing information that is
parsed from protocols which probably should be part of our tests.
There is at least one test (1999 certificates) where the entire test
output was essentially removed by the canonifier.
GH-4521 was similarly masked by this.
This commit changes the default canonifier, so that only the first
timestamp in a line is removed. This should skip timestamps that are
likely to change while keeping timestamps that are parsed
from protocol information.
A pass has been made over the tests, with some additional adjustments
for cases which require the old canonifier.
There are some cases in which we probably could go further and not
remove timestamps at all - that, however, seems like a follow-up
project.
Not the not_before/not_after fields output GMT based times.
Also adds a new btest diff canonifier which only removes the first
timestamp in a line.
Fixes GH-4521
When looking up the postprocessor function from shadow files, id::find_func()
would abort() if the function wasn't available instead of falling back
to the default postprocessor.
Fix by using id::find() and checking the type explicitly and also adding a
strict type check while at it.
This issue was tickled by loading the json-streaming-logs package,
Zeek creating shadow files containing its custom postprocessor function,
then restarting Zeek without the package loaded.
Closes#4562
