This test is very sensitive to new enum values that perturb the final
order of the output. Listing the commits that modify that file in the
past clearly shows changes to the baseline happen when a new component
with an enum value is introduced.

...
That's just distraction. Point fix the test to sort the analyzers before
writing the final log line.
I've previously attempted this in a more complete fashion in PR #3365
(issue #3364), but seems this direct fix might just make more sense.
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.
The known_log_certs table is populated asynchronously via broker after a
Broker::peer_added. It may take a variable amount of time depending on where
we run this test and it has been observed flaky specifically for the
arm_debian11 task. Instead of racing, give worker-2 3 seconds for receiving
the expected table content before continuing.
Fixes#2885
This change exposes the signature tyope inside the signed portion of an
X.509 certificate. In the past, we only exposed the signature type that
is contained inside the signature, which is outside the signed portion
of the X.509 certificate.
In theory, both signature fields should have the same value; it is,
however, possible to encode differing values in both fields. The new
field is not logged by default.
This uses the v3 json as a source for the first time. The test needed
some updating because Google removed a couple more logs - in the future
this should hopefully not be neccessary anymore because I think v3
should retain all logs.
In theory this might be neat in 5.1.
This commit adds two new bifs, x509_check_hostname and
x509_check_cert_hostname. These bifs can be used to check if a given
hostname which can, e.g., be sent in a SNI is valid for a specific
certificate.
This PR furthermore modifies the ssl logs again, and adds information
about this to the log-file. Furthermore we now by default remove the
server certificate information from ssl.log - I doubt that this is often
looked at, it is not present in TLS 1.3, we do still have the SNI, and
if you need it you have the information in x509.log.
This also fixes a small potential problem in X509.cc assuming there
might be SAN-entries that contain null-bytes.
Baseline update will follow in another commit.
The added disable-certificate-events-known-certs.zeek disables repeated
X509 events in SSL connections, given that the connection terminates at
the same server and used the samt SNI as a previously seen connection
with the same certificate.
For people that see significant amounts of TLS 1.2 traffic, this could
reduce the amount of raised events significantly - especially when a
lot of connections are repeat connections to the same servers.
The practical impact of not raising these events is actually very little
- unless a script directly interacts with the x509 events, everything
works as before - the x509 variables in the connection records are still
being set (from the cache).
By default, each certificate is now output only once per hour. This also
should work in cluster mode, where we use the net broker-table-syncing
feature to distribute the information about already seen certificates
across the entire cluster.
Log caching is also pretty configureable and can be changed using a
range of confiuration options and hooks.
Note that this is currently completely separate from X509 events
caching, which prevents duplicate parsing of X509 certificates.
This commit changes the SSL and X.509 logging formats to something that,
hopefully, slowly approaches what they will look like in the future.
X.509 log is not yet deduplicated; this will come in the future.
This commit introduces two new options, which determine if certificate
issuers and subjects are still logged in ssl.log. The default is to have
the host subject/issuer logged, but to remove client-certificate
information. Client-certificates are not a typically used feature
nowadays.
- 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.
Changed some configuration defaults to potentially more same values.
The callback function is now a hook to allow costomization of the events
that are raised.
Tests now exist. Test baselines are updated.
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
This is much more complex than the TLS Extension/OCSP cases. We need to
first alter the certificate and remove the extension from it, before
extracting the tbscert. Furthermore, we need the key hash of the issuing
certificate to be able to validate the proof - which means that we need
a valid certificate chain.
Missing: documentation, nice integration so that we can just add a
script and use this in Bro.
This does not yet work for certificates, because this requires some
changing the ASN.1 structure before validation (we need to extract the
tbscert and remove the SCT extension before).
API will change in the future.
This commit add the table SSL::ct_logs to Bro. This table is populated
with information about the currently active certificate transparency
logs (data from Google). The data can, e.g., be used to identify which
Logs are being used in SCTs.
With this change, we also parse signed certificate timestamps from OCSP
replies. This introduces a common base class between the OCSP and X509
analyzer, which now share a bit of common code. The event for signed
certificate timestamps is raised by both and thus renamed do:
x509_ocsp_ext_signed_certificate_timestamp
This is a tiny bit evil because it uses parts of the SSL protocol
analyzer in the X.509 certificate parser. Which is the fault of the
protocol, which replicates the functionality.
There was a bug in the new parsing code, introduced in
708ede22c6 which parses validity times
incorrectly if they are before the year 2000. What happens in this case
is that the 2-digit year will be interpreted to be in the 21st century
(1999 will be parsed as 2099, e.g.).
