The reason that this is necessary is the end-of-connection-handling of
spicy. If spicy is in the middle of parsing some bytes while the
connection ends, an error is raised. This behavior cannot be changed,
and means that there will be a DPD-log entry, etc. for connections that
are completely valid TLS connections - that just happen to be truncated
and end in the middle.
It turns out that, for probably a long time, we have reported an
incorrect version when parsing an SSLv2 client hello. We always reported
this as SSLv2, no matter which version the client hello actually
contained.
This bug probably went unnoticed for a long time, as SSLv2 is
essentially unused nowadays, and as this field does not show up in the
default logs.
This was found due to a baseline difference when writing the Spicy SSL
analyzer.
* origin/topic/johanna/ssl-history-also-for-sslv2-not-only-for-things-that-use-the-more-modern-handshake:
Make ssl_history work for SSLv2 handshakes/connections
It turns out that the ssl_history field never was populated with C/S for
SSLv2 connections, or connections using the SSLv2 handshake. In our
testcases, the latter is especially common - with connections up to TLS1
using the old SSLv2 client hello for backwards compatibility.
This change resolves this issue. As the history is not by default
enabled in a lot of locations, baseline impact is minor.

The Python docker-compose executable in the docker_builder image is not
functional anymore (TypeError: kwargs_from_env() got an unexpected
keyword argument 'ssl_version').
docker-compose v1 has been sun-setted for quite some time. Do the
minimal to switch to docker compose v2.
ssl-log-ext had a bug that caused data present in the SSL connection to
not be logged in some cases. Specifically, the script relied on the base
ssl script to initialize some data structures; however, this means that
protocol messages that arrive before a message is handled by the base
ssl script are not logged.
This commit changes the ssl-log-ext script to also initialize the data
structures; now messages are correctly included in the log in all cases.

The produced coverage files are of little use in current local workflows
and usually just end-up taking up disk space. ZEEK_PROFILER_FILE can be
set explicitly if there's a one-off need to produce these locally, too.
