This commit makes two changes to the validation.
Previously we would call this validation in GenerateRoot, which happens
both on initialization (when a follower becomes leader), and when a
configuration is updated. We only want to do this validation during
config update so the logic was moved to the UpdateConfiguration
function.
Previously we would compare the config values against the actual cert.
This caused problems when the cert was created manually in Vault (not
created by Consul). Now we compare the new config against the previous
config. Using a already created CA cert should never error now.
Adding the key bit and types to the config should only error when
the previous values were not the defaults.
This test found a bug in the secondary. We were appending the root cert
to the PEM, but that cert was already appended. This was failing
validation in Vault here:
https://github.com/hashicorp/vault/blob/sdk/v0.3.0/sdk/helper/certutil/types.go#L329
Previously this worked because self signed certs have the same
SubjectKeyID and AuthorityKeyID. So having the same self-signed cert
repeated doesn't fail that check.
However with an intermediate that is not self-signed, those values are
different, and so we fail the check. A test I added in a previous commit
should show that this continues to work with self-signed root certs as
well.
This is safer than embedding two interface because there are a number of
places where we check the concrete type. If we check the concrete type
on the top-level interface it will fail. So instead expose the
ACLIdentity from a method.
This change allows us to remove one of the last remaining duplicate
resolve token methods (Server.ResolveToken).
With this change we are down to only 2, where the second one also
handles setting the default EnterpriseMeta from the token.
When a wildcard xDS type (LDS/CDS/SRDS) reconnects from a delta xDS stream,
prior to envoy `1.19.0` it would populate the `ResourceNamesSubscribe` field
with the full list of currently subscribed items, instead of simply omitting it
to infer that it wanted everything (which is what wildcard mode means).
This upstream issue was filed in envoyproxy/envoy#16063 and fixed in
envoyproxy/envoy#16153 which went out in Envoy `1.19.0` and is fixed in later
versions (later refactored in envoyproxy/envoy#16855).
This PR conditionally forces LDS/CDS to be wildcard-only even when the
connected Envoy requests a non-wildcard subscription, but only does so on
versions prior to `1.19.0`, as we should not need to do this on later versions.
This fixes the failure case as described here: #11833 (comment)

Now that ACLResolver is embedded we don't need ResolveTokenToIdentity on
Client and Server.
Moving ResolveTokenAndDefaultMeta to ACLResolver removes the duplicate
implementation.

The gist here is that now we use a value-type struct proxycfg.UpstreamID
as the map key in ConfigSnapshot maps where we used to use "upstream
id-ish" strings. These are internal only and used just for bidirectional
trips through the agent cache keyspace (like the discovery chain target
struct).
For the few places where the upstream id needs to be projected into xDS,
that's what (proxycfg.UpstreamID).EnvoyID() is for. This lets us ALWAYS
inject the partition and namespace into these things without making
stuff like the golden testdata diverge.
Remove some unnecessary comments around query_blocking metric. The only
line that needs any comments in the atomic decrement.
Cleanup the block and return comments and logic. The old comment about
AbandonCh may have been relevant before, but it is expected behaviour
now.
The logic was simplified by inverting the err condition.
This helps keep the logic in blockingQuery more focused. In the future we
may have a separate struct for RPC queries which may allow us to move this
off of Server.
This safeguard should be safe to apply in general. We are already
applying it to non-blocking queries that call blockingQuery, so it
should be fine to apply it to others.
To remove the TODO, and make it more readable.
In general this reduces the scope of variables, making them easier to reason about.
It also introduces more early returns so that we can see the flow from the structure
of the function.

`newIntermediate` is always equal to `needsNewIntermediate`, so we can
remove the extra variable and use the original directly.
Also remove the `activeRoot.ID != newActiveRoot.ID` case from an if,
because that case is already checked above, and `needsNewIntermediate` will
already be true in that case.
This condition now reads a lot better:
> Persist a new root if we did not have one before, or if generated a new intermediate.
In the previous commit the single use of this storedRoot was removed.
In this commit the original objective is completed. The
Provider.ActiveRoot is being removed because
1. the secondary should get the active root from the Consul primary DC,
not the provider, so that secondary DCs do not need to communicate
with a provider instance in a different DC.
2. so that the Provider.ActiveRoot interface can be changed without
impacting other code paths.
This method had only one caller, which always looked for the active
root. This commit moves the lookup into the method to reduce the logic
in the one caller.
This is being done in preparation for a larger change. Keeping this
separate so it is easier to see.
The `storedRootID != primaryRoots.ActiveRootID` is being removed because
these can never be different.
The `storedRootID` comes from `provider.ActiveRoot`, the
`primaryRoots.ActiveRootID` comes from the store `CARoot` from the
primary. In both cases the source of the data is the primary DC.
Technically they could be different if someone modified the provider
outside of Consul, but that would break many things, so is not a
supported flow.
If these were out of sync because of ordering of events then the
secondary will soon receive an update to `primaryRoots` and everything
will be sorted out again.
