The TrustDomain is populated from the Host() method which includes the
hard-coded "consul" domain. This means that despite having an empty
cluster ID, the TrustDomain won't be empty.
There are two restrictions:
- Writes from the primary DC which explicitly target a secondary DC.
- Writes to a secondary DC that do not explicitly target the primary DC.
The first restriction is because the config entry is not supported in
secondary datacenters.
The second restriction is to prevent the scenario where a user writes
the config entry to a secondary DC, the write gets forwarded to the
primary, but then the config entry does not apply in the secondary.
This makes the scope more explicit.
The duo of `makeUpstreamFilterChainForDiscoveryChain` and `makeListenerForDiscoveryChain` were really hard to reason about, and led to concealing a bug in their branching logic. There were several issues here:
- They tried to accomplish too much: determining filter name, cluster name, and whether RDS should be used.
- They embedded logic to handle significantly different kinds of upstream listeners (passthrough, prepared query, typical services, and catch-all)
- They needed to coalesce different data sources (Upstream and CompiledDiscoveryChain)
Rather than handling all of those tasks inside of these functions, this PR pulls out the RDS/clusterName/filterName logic.
This refactor also fixed a bug with the handling of [UpstreamDefaults](https://www.consul.io/docs/connect/config-entries/service-defaults#defaults). These defaults get stored as UpstreamConfig in the proxy snapshot with a DestinationName of "*", since they apply to all upstreams. However, this wildcard destination name must not be used when creating the name of the associated upstream cluster. The coalescing logic in the original functions here was in some situations creating clusters with a `*.` prefix, which is not a valid destination.
Fixes an issue described in #10132, where if two DCs are WAN federated
over mesh gateways, and the gateway in the non-primary DC is terminated
and receives a new IP address (as is commonly the case when running them
on ephemeral compute instances) the primary DC is unable to re-establish
its connection until the agent running on its own gateway is restarted.
This was happening because we always preferred gateways discovered by
the `Internal.ServiceDump` RPC (which would fail because there's no way
to dial the remote DC) over those discovered in the federation state,
which is replicated as long as the primary DC's gateway is reachable.
Currently getCARoots could return an empty object with an empty trust
domain before the CA is initialized. This commit returns an error while
there is no CA config or no trust domain.
There could be a CA config and no trust domain because the CA config can
be created in InitializeCA before initialization succeeds.

Previously secondaryInitialize would return nil in this case, which prevented the
deferred initialize from happening, and left the CA in an uninitialized state until a config
update or root rotation.
To fix this I extracted the common parts into the delegate implementation. However looking at this
again, it seems like the handling in secondaryUpdateRoots is impossible, because that function
should never be called before the secondary is initialzied. I beleive we can remove some of that
logic in a follow up.
These two fields do not appear to be used anywhere. We use the structs.ACLPolicy ID in the
ACLResolver cache, but the acl.Policy ID and revision are not used.
* Support Vault Namespaces explicitly in CA config
If there is a Namespace entry included in the Vault CA configuration,
set it as the Vault Namespace on the Vault client
Currently the only way to support Vault namespaces in the Consul CA
config is by doing one of the following:
1) Set the VAULT_NAMESPACE environment variable which will be picked up
by the Vault API client
2) Prefix all Vault paths with the namespace
Neither of these are super pleasant. The first requires direct access
and modification to the Consul runtime environment. It's possible and
expected, not super pleasant.
The second requires more indepth knowledge of Vault and how it uses
Namespaces and could be confusing for anyone without that context. It
also infers that it is not supported

This is a potential security issue because an attacker could conceivably manipulate inputs to cause persistence files to collide, effectively deleting the persistence file for one of the colliding elements.

(DNS, HTTP, HTTPS, GRPC) are not listening and the user is not notified
in any way about what's happening.
Also, since a not provided client_addr defaults to 127.0.0.1, we make sure
we are not getting unwanted warnings

This will behave the way we handle SNI and SPIFFE IDs, where the default
partition is excluded.
Excluding the default ensures that don't attempt to compare default.dc2
to dc2 in OSS.
The api module has decoding functions that rely on 'kind' being present
of payloads. This is so that we can decode into the appropriate api type
for the config entry.
This commit ensures that a static kind is marshalled in responses from
Consul's api endpoints so that the api module can decode them.
These labels should be set by whatever process scrapes Consul (for
prometheus), or by the agent that receives them (for datadog/statsd).
We need to remove them here because the labels are part of the "metric
key", so we'd have to pre-declare the metrics with the labels. We could
do that, but that is extra work for labels that should be added from
elsewhere.
Also renames the closure to be more descriptive.
Prometheus scrapes metrics from each process, so when leadership transfers to a different node
the previous leader would still be reporting the old cached value.
By setting NaN, I believe we should zero-out the value, so that prometheus should only consider the
value from the new leader.
Emit the metric immediately so that after restarting an agent, the new expiry time will be
emitted. This is particularly important when this metric is being monitored, because we want
the alert to resovle itself immediately.
Also fixed a bug that was exposed in one of these metrics. The CARoot can be nil, so we have
to handle that case.
TestSubscribeBackend_IntegrationWithServer_DeliversAllMessages has been
flaking a few times. This commit cleans up the test a bit, and improves
the failure output.
I don't believe this actually fixes the flake, but I'm not able to
reproduce it reliably.
The failure appears to be that the event with Port=0 is being sent in
both the snapshot and as the first event after the EndOfSnapshot event.
Hopefully the improved logging will show us if these are really
duplicate events, or actually different events with different indexes.
This commit updates mesh gateway watches for cross-partitions
communication.
* Mesh gateways are keyed by partition and datacenter.
* Mesh gateways will now watch gateways in partitions that export
services to their partition.
* Mesh gateways in non-default partitions will not have cross-datacenter
watches. They are not involved in traditional WAN federation.
partitionAuthorizer.config can be nil if it wasn't provided on calls to
newPartitionAuthorizer outside of the ACLResolver. This usage happens
often in tests.
This commit: adds a nil check when the config is going to be used,
updates non-test usage of NewPolicyAuthorizerWithDefaults to pass a
non-nil config, and dettaches setEnterpriseConf from the ACLResolver.
When issuing cross-partition service discovery requests, ACL filtering
often checks for NodeRead privileges. This is because the common return
type is a CheckServiceNode, which contains node data.
Previously the datacenter of the gateway was the key identifier, now it
is the datacenter and partition.
When dialing services in other partitions or datacenters we now watch
the appropriate partition.
useInDatacenter was used to determine whether the mesh gateway mode of
the upstream should be returned in the discovery chain target. This
commit makes it so that the mesh gateway mode is returned every time,
and it is up to the caller to decide whether mesh gateways should be
watched or used.
