The wrapper is sometimes unset at the time when the
audit config is validated, so it is impossible for us
to validate that a valid wrapper is configured. The wrapper
is configured by later setup steps because of a dependency
on the eventer in our KMS setup.
This contains to related things:
1. An adapter allowing an hclog interface to take in information and send them to the eventer
2. A gate on the eventer, which is the analogue to the behavior prior to eventing where we'd ensure logs were not printed prior to the startup information. Without this, plugin logs using the hclog adapter will start showing up too early.
This stores worker connection nonces within the database to ensure
uniqueness of connections. Prior the connection required any attacker to
be able to decrypt the incoming encrypted authentication message in
order to replay (and if the attacker has access to the KMS you have
bigger problems), but with this change even if an attacker does have
access to the KMS key, they cannot reuse the same message. (If they're
able to encrypt against the KMS key, they can still act as a worker with
a new message, so this only really helps if they only have decryption
capabilities.)
* feat (events): Add new options needed for AuditConfig
WithAuditWrapper and WithFilterOperations all for optional paramters
when creating AuditConfig types.
* refactor (event): Change EventerConfig.Sinks to a ptr
We need to modify the SinkConfig.AuditConfig during the NewEventer factory, so we have to use a ptr not a ref.
* feat (events): Add audit configuration types
* feat (events): add audit config to sink configuration.
* feat (events): add redact/encrypt node for audit events to Eventer
Integrate the encrypt.Filter node from the eventlogger into the
event.Eventer, so audit events can be redacted/encrypted based
on data classifications.
* test (events) Add test protobufs for events
Add test protobufs along with a test service for testing
the audit event encrypt node
* Normalize event configuration
This updates event configuration stanzas to more closely match behavior
for listeners and kmses:
* Singular "sink" instead of "sinks" (probably not the most correct
option, but a consistent option, and one that makes sense for HCL)
* Allows sinks to have the type defined at the start of the block
* Moves type-specific configuration to a specific named block
