This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.
This change was made by GoLand refactor, which did most of the work for me.
This method suffered from similar naming to a couple other methods on Server, and had not great
re-use (2 callers). By copying a few of the lines into one of the callers we can move the
implementation into the second caller.
Once moved, we can see that ResolveTokenAndDefaultMeta is identical in both Client and Server, and
likely should be further refactored, possibly into ACLResolver.
This change is being made to make ACL resolution easier to trace.
This method was an alias for ACLResolver.ResolveTokenToIdentityAndAuthorizer. By removing the
method that does nothing the code becomes easier to trace.
ACL filtering only needs an authorizer and a logger. We can decouple filtering from
the ACLResolver by passing in the necessary logger.
This change is being made in preparation for moving the ACLResolver into an acl package
filterACLWithAuthorizer could never return an error. This change moves us a little bit
closer to being able to enable errcheck and catch problems caused by unhandled error
return values.
These functions are moved to the one place they are called to improve code locality.
They are being moved out of agent/consul/acl.go in preparation for moving
ACLResolver to an acl package.
These functions are used in only one place. Move the functions next to their one caller
to improve code locality.
This change is being made in preparation for moving the ACLResolver into an
acl package. The moved functions were previously in the same file as the ACLResolver.
By moving them out of that file we may be able to move the entire file
with fewer modifications.

Previously we were passing an Authorizer that would always allow the
operation, then later checking the authorization using vetServiceTxnOp.
On the surface this seemed strange, but I think it was actually masking
a bug as well. Over time `servicePreApply` was changed to add additional
authorization for `service.Proxy.DestinationServiceName`, but because
we were passing a nil Authorizer, that authorization was not handled on
the txn_endpoint.
`TxnServiceOp.FillAuthzContext` has some special handling in enterprise,
so we need to make sure to continue to use that from the Txn endpoint.
This commit removes the `vetServiceTxnOp` function, and passes in the
`FillAuthzContext` function so that `servicePreApply` can be used by
both the catalog and txn endpoints. This should be much less error prone
and prevent bugs like this in the future.

Move the check for the Intention.DestinationName into the Authorizer to remove the
need to check what kind of Authorizer is being used.
It sounds like this check is only for legacy ACLs, so is probably just a safeguard
.
1. do not emit the metric if Query fails
2. properly check for PrimaryUsersIntermediate, the logic was inverted
Also improve the logging by including the metric name in the log message

These checks were a bit more involved. They were previously skipping some code paths
when the authorizer was nil. After looking through these it seems correct to remove the
authz == nil check, since it will never evaluate to true.
These case are already impossible conditions, because most of these functions already start
with a check for ACLs being disabled. So the code path being removed could never be reached.
The one other case (ConnectAuthorized) was already changed in a previous commit. This commit
removes an impossible branch because authz == nil can never be true.
These methods are no longer used. Remove the methods, and update the
tests to use actual method used by production code.
Also removes the 'authz == nil' check is no longer a possible code path
now that we are returning a non-nil acl.Authorizer when ACLs are disabled.
The blocking query backend sets the default value on the server side.
The streaming backend does not using blocking queries, so we must set the timeout on
the client.
Now that we have at least one endpoint that uses context for cancellation we can
encounter this scenario where the returned error is a context.Cancelled or
context.DeadlineExceeded.
If the request.Context().Err() is not nil, then we know the request itself was cancelled, so
we can log a different message at Info level, instad of the error.
Knowing that blocking queries are firing does not provide much
information on its own. If we know the correlation IDs we can
piece together which parts of the snapshot have been populated.
Some of these responses might be empty from the blocking
query timing out. But if they're returning quickly I think we
can reasonably assume they contain data.

If multiple instances of a service are co-located on the same node then
their proxies will all share a cache entry for their resolved service
configuration. This is because the cache key contains the name of the
watched service but does not take into account the ID of the watching
proxies.
This means that there will be multiple agent service manager watches
that can wake up on the same cache update. These watchers then
concurrently modify the value in the cache when merging the resolved
config into the local proxy definitions.
To avoid this concurrent map write we will only delete the key from
opaque config in the local proxy definition after the merge, rather
than from the cached value before the merge.
This change adds a new `dns_config.recursor_strategy` option which
controls how Consul queries DNS resolvers listed in the `recursors`
config option. The supported options are `sequential` (default), and
`random`.

A previous commit used SetHash on two of the cases to fix a data race. This commit applies
that change to all cases. Using SetHash in this test helper should ensure that the
test helper behaves closer to production.
These changes ensure that the identity of services dialed is
cryptographically verified.
For all upstreams we validate against SPIFFE IDs in the format used by
Consul's service mesh:
spiffe://<trust-domain>/ns/<namespace>/dc/<datacenter>/svc/<service>
The dnsConfig pulled from the atomic.Value is a pointer, so modifying it in place
creates a data race. Use the exported ReloadConfig interface instead.
The LogOutput io.Writer used by TestAgent must allow concurrent reads and writes, and a
bytes.Buffer does not allow this. The bytes.Buffer must be wrapped with a lock to make this safe.
Some global variables are patched to shorter values in these tests. But the goroutines that read
them can outlive the test because nothing waited for them to exit.
This commit adds a Wait() method to the routine manager, so that tests can wait for the goroutines
to exit. This prevents the data race because the 'reset to original value' can happen
after all other goroutines have stopped.
A previous commit started using QueryRefuced, but that is not correct. QueryRefuced refers to
the OpCode, not the query type.
Instead use errNoAnswer because we have no records for that query type.
Now that trimDNSResponse is handled by the caller we don't need to pass this value
around. We can remove it from both the serviceLookup struct, and two functions.
The dispatch function was called from a single place and did nothing but add a default value.
Removing it makes code easier to trace by removing an unnecessary hop.
The compatv2 integration tests were failing because they use an older CLI version with a newer
HTTP API. This commit restores the GRPCPort field to the DebugConfig output to allow older
CIs to continue to fetch the port.
The DebugConfig in the self endpoint can change at any time. It's not a stable API.
With the previous change to rename GRPCPort to XDSPort this command would have broken.
This commit adds the XDSPort to a stable part of the XDS api, and changes the envoy command to read
this new field.
It includes support for the old API as well, in case a newer CLI is used with an older API, and
adds a test for both cases.

Most of these methods are used exclusively for the AutoConfig RPC
endpoint. This PR uses a pattern that we've used in other places as an
incremental step to reducing the scope of Server.
raftApply was removed so ApplyCARequest needs to handle all the possible operations
Also set the providerShim to use the mock provider.
other changes are small test improvements that were necessary to debug the failures.
and small refactor to getCAProvider so that GoLand is less confused about what it is doing.
Previously it was reporting that the for condition was always true, which was not the case.
After moving ca.ConsulProviderStateDelegate into the interface we now
have the ApplyCARequest method which does the same thing. Use this more
specific method instead of raftApply.
This field was documented as enabling TLS for outgoing RPC, but that was not the case.
All this field did was set the use_tls serf tag.
Instead of setting this field in a place far from where it is used, move the logic to where
the serf tag is set, so that the code is much more obvious.
tlsutil.Config already presents an excellent structure for this
configuration. Copying the runtime config fields to agent/consul.Config
makes code harder to trace, and provides no advantage.
Instead of copying the fields around, use the tlsutil.Config struct
directly instead.
This is one small step in removing the many layers of duplicate
configuration.

And remove BuildAndValidate. This commit completes some earlier work to reduce the config
interface a single Load function.
The last remaining test was converted to use Load instad of BuildAndValidate.
Previously, for a POST request to the /v1/operator/autopilot/configuration
endpoint, any fields not included in the payload were set to a zero-initialized
value rather than the documented default value.
Now, if an optional field is not included in the payload, it will be set to its
documented default value:
- CleanupDeadServers: true
- LastContactThreshold: "200ms"
- MaxTrailingLogs: 250
- MinQuorum: 0
- ServerStabilizationTime: "10s"
- RedundancyZoneTag: ""

The hcl decoding apparently uses strconv.ParseInt, which fails to parse a 64bit int.
Since hcl v1 is basically EOl, it seems unlikely we'll fix this in hcl.
Since this test is only about loading values from config files, the extra large number
doesn't seem important. Trim a few zeros from the numbers so that they parse
properly on 32bit platforms.
Also skip a slow test when -short is used.
sync/atomic must be used with 64-bit aligned fields, and that alignment is difficult to
ensure unless the field is the first one in the struct.
https://golang.org/pkg/sync/atomic/#pkg-note-BUG.
If a value was already available in the local view the request is considered a cache hit.
If the materialized had to wait for a value, it is considered a cache miss.
This test is super racy (it's not just a single line).
This test also starts failing once streaming is enabled, because the
cache rate limit no longer applies to the requests in the test. The
queries use streaming instead of the cache.
This test is no longer valid, and the functionality is already well
tested by TestCacheThrottle. Instead of spending time rewriting this
test, let's remove it.

The query metrics are actually reported for all read queries, not only
ones that use a MinIndex to block for updates.
Also clarify the raft.apply metric is only on the leader.
As part of this change, we ensure that the SAN extensions are marked as
critical when the subject is empty so that AWS PCA tolerates the loss of
common names well and continues to function as a Connect CA provider.
Parts of this currently hack around a bug in crypto/x509 and can be
removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.
Note: the AWS PCA tests do not run automatically, but the following
passed locally for me:
