The main part of this commit are changes in tests. A lot of the tests
that previously relied on analyzer.log or dpd.log now use the new
analyzer-failed.log.
I verified all the changes and, as far as I can tell, everything
behaves as it should. This includes the external test baselines.
This change also enables logging of file and packet analyzer to
analyzer_failed.log and fixes some small behavior issues.
The analyzer_failed event is no longer raised when the removal of an
analyzer is vetoed.
If an analyzer is no longer active when an analyzer violation is raised,
currently the analyzer_failed event is raised. This can, e.g., happen
when an analyzer error happens at the very end of the connection. This
makes the behavior more similar to what happened in the past, and also
intuitively seems to make sense.
A bug introduced in the failed service logging was fixed.
With this commit, the entire Zeek test suite passes using spicy TLS.
Tests that either use a SSLv2 handshake, or DTLS are skipped, as the
parser currently does not support either.
Similarly, tests that rely on behavior we cannot replicate (baseline,
hooks, exact error messages) are passed. Other than that, all the
TLS-based tests pass with 100% the exact same baseline results.
This necessitated a couple of small tweaks to the spicy file - the
testcases uncovered several small problems.
This commit also enables cirrus tests for Spicy SSL/TLS.
This commit adds support for the connection_id extension, adds a trace
that uses DTLS 1.3 connection IDs, and adds parsing for the DTLS 1.3
unified header, in case connection IDs are not used.
In case connection IDs are used, parsing of the DTLS 1.3 unified header
is skipped. This is due to the fact, that the header then contains a
variable length element, with the length of the element not given in the
header. Instead, the length is given in the client/server hello message
of the opposite side of the connection (which we might have missed).
Furthermore, parsing is not of a high importance, since we are not
passing the connection ID, or any of the other parsed values of the
unified header into scriptland.
DTLSv1.3 changes the DTLS record format, introducing a completely new
header - which is a first for DTLS.
We don't currently completely parse this header, as this requires a bit
more statekeeping. This will be added in a future revision. This also
also has little practical implications.
