Remove caching_sha2_password parsing/state from the analyzer and implement
the generic events. If we actually want to peak into the authentication
mechanism, we could write a separate analyzer for it. For now, treat it
as opaque values that are exposed to script land.
The added tests show the --get-server-public-key in use where
mysql_auth_more_data contains an RSA public key.

minor optimization of boolean comparisons
fix & regression test for GH-3839 (spurious warnings for "when" constructs)
Instead of dissecting the GSSAPI handshake, add another heuristic
into MaybeEncrypted to check for the WRAP token identifier.
After this change, the pcap on the following ticket is processed
nicely: https://gitlab.com/wireshark/migration-test/-/issues/9398
@dopheide-esnet provided sample captures where SASL SRP is used as
a SASL mechanism and the follow-up LDAP messages are encrypted. It's
not clear how to determine whether encryption will or will not happen,
so re-add a heuristic to determine this based on the first byte of
the first message *after* the successful bindResponse handshake. If
that byte is 0x30, assume cleartext.
I haven't been able to produce such pcaps, unfortunately, but the
cleartext path is tested via the existing sasl-ntlm.pcap.
PCAP was produced with a local OpenLDAP server configured to support StartTLS.
This puts the Zeek calls into a separate ldap_zeek.spicy file/module
to separate it from LDAP.
With Cluster::Node$metrics_port being optional, there's not really
a need for the extra script. New rule, if a metrics_port is set, the
node will attempt to listen on it.
Users can still redef Telemetry::metrics_port *after*
base/frameworks/telemetry was loaded to change the port defined
in cluster-layout.zeek.
This unit implements a heuristic to search for the 0x30 sequence
byte if Message couldn't readily be parsed. Remove it with the
idea of explicit and predictable support for SASL mechanisms.
ASN1Message(True) may go off parsing arbitrary input data as
"something ASN.1" This could be GBs of octet strings or just very
long sequences. Avoid this by open-coding some top-level types expected.
This also tries to avoid some of the &parse-from usages that result
in unnecessary copies of data.
Adds a locally generated PCAP with addRequest/addResponse that we
don't currently handle.
Mostly staring at the PCAPs and opened a few RFCs. For now, only if the
MS_KRB5 OID is used and accepted in a bind response, start stripping
KRB5 wrap tokens for both, client and server traffic.
Would probably be nice to forward the GSS-API data to the analyzer...
Closeszeek/spicy-ldap#29.
This patch bump Spicy to the latest development snapshot. This
introduces a backwards-incompatible change in that it removes support
for a never officially supported syntax to specify unit fields (so I
would argue: not strictly a breaking change).
I merged an old version of the branch on accident and then merged the right
one over top of it, but git ended up including both versions. This fixes
that mistake.
