I suspect one problem was that we set structs.IntermediateCertRenewInterval to 1ms, which meant
that in some cases the intermediate could renew before we stored the original value.
Another problem was that the 'wait for intermediate' loop was calling the provider.ActiveIntermediate,
but the comparison needs to use the RPC endpoint to accurately represent a user request. So
changing the 'wait for' to use the state store ensures we don't race.
Also moves the patching into a separate function.
Removes the addition of ca.CertificateTimeDriftBuffer as part of calculating halfTime. This was added
in a previous commit to attempt to fix the flake, but it did not appear to fix the problem. Adding the
time here was making the tests fail when using the shared patch
function. It's not clear to me why, but there's no reason we should be
including this time in the halfTime calculation.
Use the new verifyLearfCert to show the cert verifies with intermediates
from both sources. This required using the RPC interface so that the
leaf pem was constructed correctly.
Add IndexedCARoots.Active since that is a common operation we see in a
few places.
Previously we had a couple copies that reproduced the FSM operation.
These copies introduce risk that the test does not accurately match
production.
This PR removes the test versions of the FSM operation, and exports the
real production FSM operation so that it can be used in tests.
The consul provider tests did need to change because of this. Previously
we would return a hardcoded value of 2, but in production this value is
always incremented.
Failing over to a partition is more siimilar to failing over to another
datacenter than it is to failing over to a namespace. In a future
release we should update how localities for failover are specified. We
should be able to accept a list of localities which can include both
partition and datacenter.
* Add partition fields to targets like service route destinations
* Update validation to prevent cross-DC + cross-partition references
* Handle partitions when reading config entries for disco chain
* Encode partition in compiled targets
Fixes a bug whereby servers present in multiple network areas would be
properly segmented in the Router, but not in the gRPC mirror. This would
lead servers in the current datacenter leaving from a network area
(possibly during the network area's removal) from deleting their own
records that still exist in the standard WAN area.
The gRPC client stack uses the gRPC server tracker to execute all RPCs,
even those targeting members of the current datacenter (which is unlike
the net/rpc stack which has a bypass mechanism).
This would manifest as a gRPC method call never opening a socket because
it would block forever waiting for the current datacenter's pool of
servers to be non-empty.
Given that we do not allow wildcard partitions in intentions, no one ixn
can override the DefaultAllow setting. Only the default ACL policy
applies across all partitions.
This table purposefully does not index by partition/namespace. It's a
global view into all service names.
This table is intended to replace the current serviceListTxn watch in
intentionTopologyTxn. For cross-partition transparent proxying we need
to be able to calculate upstreams from intentions in any partition. This
means that the existing serviceListTxn function is insufficient since
it's scoped to a partition.
Moving away from that function is also beneficial because it watches the
main "services" table, so watchers will wake up when any instance is
registered or deregistered.

Cross port of ent #1383 "Reject non-default datacenter when making partitioned ACLs"
On the OSS side this is a minor refactor to add some more checks that are only applicable to enterprise code.
Signed-off-by: Mark Anderson <manderson@hashicorp.com>
The test added in this commit shows the problem. Previously the
SigningKeyID was set to the RootCert not the local leaf signing cert.
This same bug was fixed in two other places back in 2019, but this last one was
missed.
While fixing this bug I noticed I had the same few lines of code in 3
places, so I extracted a new function for them.
There would be 4 places, but currently the InitializeCA flow sets this
SigningKeyID in a different way, so I've left that alone for now.
While working on the CA system it is important to be able to run all the
tests related to the system, without having to wait for unrelated tests.
There are many slow and unrelated tests in agent/consul, so we need some
way to filter to only the relevant tests.
This PR renames all the CA system related tests to start with either
`TestCAMananger` for tests of internal operations that don't have RPC
endpoint, or `TestConnectCA` for tests of RPC endpoints. This allows us
to run all the test with:
go test -run 'TestCAMananger|TestConnectCA' ./agent/consul
The test naming follows an undocumented convention of naming tests as
follows:
Test[<struct name>_]<function name>[_<test case description>]
I tried to always keep Primary/Secondary at the end of the description,
and _Vault_ has to be in the middle because of our regex to run those
tests as a separate CI job.
You may notice some of the test names changed quite a bit. I did my best
to identify the underlying method being tested, but I may have been
slightly off in some cases.
As a method on the struct type this would not be safe to call without first checking
c.isIntermediateUsedToSignLeaf.
So for now, move this logic to the CAMananger, so that it is always correct.
We were not adding the local signing cert to the CARoot. This commit
fixes that bug, and also adds support for fixing existing CARoot on
upgrade.
Also update the tests for both primary and secondary to be more strict.
Check the SigningKeyID is correct after initialization and rotation.
Validation was added on the config entry kind since that is called when
validating config entries to bootstrap via agent configuration and when
applying entries via the config RPC endpoint.
Previously we believe it was necessary for all code that required ports
to use freeport to prevent conflicts.
https://github.com/dnephin/freeport-test shows that it is actually save
to use port 0 (`127.0.0.1:0`) as long as it is passed directly to
`net.Listen`, and the listener holds the port for as long as it is
needed.
This works because freeport explicitly avoids the ephemeral port range,
and port 0 always uses that range. As you can see from the test output
of https://github.com/dnephin/freeport-test, the two systems never use
overlapping ports.
This commit converts all uses of freeport that were being passed
directly to a net.Listen to use port 0 instead. This allows us to remove
a bit of wrapping we had around httptest, in a couple places.
In d2ab767fef21244e9fe3b9887ea70fc177912381 raftApply was changed to handle this check in
a single place, instad of having every caller check it. It looks like these few places
were missed when I did that clean up.
This commit removes the remaining resp.(error) checks, since they are all no-ops now.
This function is only ever called from operations that have already acquired the state lock, so checking
the value of state can never fail.
This change is being made in preparation for splitting out a separate type for the secondary logic. The
state can't easily be shared, so really only the expored top-level functions should acquire the 'state lock'.
This commit removes the actingSecondaryCA field, and removes the stateLock around it. This field
was acting as a proxy for providerRoot != nil, so replace it with that check instead.
The two methods which called secondarySetCAConfigured already set the state, so checking the
state again at this point will not catch runtime errors (only programming errors, which we can catch with tests).
In general, handling state transitions should be done on the "entrypoint" methods where execution starts, not
in every internal method.
This is being done to remove some unnecessary references to c.state, in preparations for extracting
types for primary/secondary.
This makes it easier to fake, which will allow me to use the ConsulProvider as
an 'external PKI' to test a customer setup where the actual root CA is not
the root we use for the Consul CA.
Replaces a call to the state store to fetch the clusterID with the
clusterID field already available on the built-in provider.

* Support vault auth methods for the Vault connect CA provider
* Rotate the token (re-authenticate to vault using auth method) when the token can no longer be renewed
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 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.
Existing config entries prefixed by service- are specific to individual
services. Since this config entry applies to partitions it is being
renamed.
Additionally, the Partition label was changed to Name because using
Partition at the top-level and in the enterprise meta was leading to the
enterprise meta partition being dropped by msgpack.
The code for this was already removed, which suggests this is not actually testing what it claims.
I'm guessing these are still resolving because the tokens are converted to non-legacy tokens?
It seems like this was missing. Previously this was only called by init of ACLs during an upgrade.
Now that legacy ACLs are removed, nothing was calling stop.
Also remove an unused method from client.
To make it more clear which methods are necessary for each scenario. This can
also prevent problems which force all DCs to use the same Vault instance, which
is currently a problem.
This function is only run when the CAManager is a primary. Extracting this function
makes it clear which parts of UpdateConfiguration are run only in the primary and
also makes the cleanup logic simpler. Instead of both a defer and a local var we
can call the cleanup function in two places.
This commit renames functions to use a consistent pattern for identifying the functions that
can only be called when the Manager is run as the primary or secondary.
This is a step toward eventually creating separate types and moving these methods off of CAManager.

This commit two test failures:
1. Remove check for "in legacy ACL mode", the actual upgrade will be removed in a following commit.
2. Remove the early WaitForLeader in dc2, because with it the test was
failing with ACL not found.
TestAgentLeaks_Server was reporting a goroutine leak without this. Not sure if it would actually
be a leak in production or if this is due to the test setup, but seems easy enough to call it
this way until we remove legacyACLTokenUpgrade.
We no long need to read the acl serf tag, because servers are always either ACL enabled or
ACL disabled.
We continue to write the tag so that during an upgarde older servers will see the tag.
This commit two test failures:
1. Remove check for "in legacy ACL mode", the actual upgrade will be removed in a following commit.
2. Use the root token in WaitForLeader, because without it the test was
failing with ACL not found.
As part of removing the legacy ACL system ACL upgrading and the flag for
legacy ACLs is removed from Clients.
This commit also removes the 'acls' serf tag from client nodes. The tag is only ever read
from server nodes.
This commit also introduces a constant for the acl serf tag, to make it easier to track where
it is used.
The DebugConfig in the self endpoint can change at any time. It's not a stable API.
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.
Replace it with an implementation that returns an error, and rename some symbols
to use a Deprecated suffix to make it clear.
Also remove the ACLRequest struct, which is no longer referenced.
These methods only called a single function. Wrappers like this end up making code harder to read
because it adds extra ways of doing things.
We already have many helper functions for constructing these types, we don't need additional methods.
When converting these tests from the legacy ACL system to the new RPC endpoints I
initially changed most things to use _prefix rules, because that was equivalent to
the old legacy rules.
This commit modifies a few of those rules to be a bit more specific by replacing the _prefix
rule with a non-prefix one where possible.
This struct allows us to move all the deprecated config options off of
the main config struct, and keeps all the deprecation logic in a single
place, instead of spread across 3+ places.
In preparation for removing ACL.Apply.
Tests for ACL.Apply, ACL.GetPolicy, and ACL upgrades were removed
because all 3 of those will be removed shortly.
The forth test appears to be for the ACLResolver cache, so the test was moved to the correct
test file, and the name was updated to make it obvious what is being tested.
structs.ACLForceSet was deprecated 4 years ago, it should be safe to remove now.
ACLBootstrapNow was removed in a recent commit. While it is technically possible that a cluster with mixed version
could still attempt a legacy boostrap, we documented that the legacy system was deprecated in 1.4, so no
clusters that are being upgraded should be attempting a legacy boostrap.
Fixes#10563
The `resourceVersion` map was doing two jobs prior to this PR. The first job was
to track what version of every resource we know envoy currently has. The
second was to track subscriptions to those resources (by way of the empty
string for a version). This mostly works out fine, but occasionally leads to
consul removing a resource and accidentally (effectively) unsubscribing at the
same time.
The fix separates these two jobs. When all of the resources for a subscription
are removed we continue to track the subscription until envoy explicitly
unsubscribes

* agent: add failures_before_warning setting
The new setting allows users to specify the number of check failures
that have to happen before a service status us updated to be `warning`.
This allows for more visibility for detected issues without creating
alerts and pinging administrators. Unlike the previous behavior, which
caused the service status to not update until it reached the configured
`failures_before_critical` setting, now Consul updates the Web UI view
with the `warning` state and the output of the service check when
`failures_before_warning` is breached.
The default value of `FailuresBeforeWarning` is the same as the value of
`FailuresBeforeCritical`, which allows for retaining the previous default
behavior of not triggering a warning.
When `FailuresBeforeWarning` is set to a value higher than that of
`FailuresBeforeCritical it has no effect as `FailuresBeforeCritical`
takes precedence.

Previously SAN validation for prepared queries was broken because we
validated against the name, namespace, and datacenter for prepared
queries.
However, prepared queries can target:
- Services with a name that isn't their own
- Services in multiple datacenters
This means that the SpiffeID to validate needs to be based on the
prepared query endpoints, and not the prepared query's upstream
definition.
This commit updates prepared query clusters to account for that.

and now that name is overridable.
- The discovery chain snapshot didn't have prepared query endpoints so
the endpoints tests were missing data for prepared queries
Remove the error return, so that not handling is not reported as an
error by errcheck. It was returning the error passed as an arg
unmodified so there is no reason to return the same value that was
passed in.
Remove the term upstreams to remove any confusion with the term used in
service mesh.
Remove the AutoDisable field, and replace it with the TTL value, using 0
to indicate the setting is turned off.
Replace "not Before" with "After".
Add some test coverage to show the behaviour is still correct.
This field was never user-configurable. We always overwrote the value with 120s from
NonUserSource. However, we also never copied the value from RuntimeConfig to consul.Config,
So the value in NonUserSource was always ignored, and we used the default value of 30s
set by consul.DefaultConfig.
All of this code is an unnecessary distraction because a user can not actually configure
this value.
This commit removes the fields and uses a constant value instad. Someone attempting to set
acl.disabled_ttl in their config will now get an error about an unknown field, but previously
the value was completely ignored, so the new behaviour seems more correct.
We have to keep this field in the AutoConfig response for backwards compatibility, but the value
will be ignored by the client, so it doesn't really matter what value we set.
Tests only specified one of the fields, but in production we copy the
value from a single place, so we can do the same in tests.
The AutoConfig test broke because of the problem noticed in a previous
commit. The DisabledTTL is not wired up properly so it reports 0s here.
Changed the test to use an explicit value.

Renames all variables for acl.Authorizer to use `authz`. Previously some
places used `rule` which I believe was an old name carried over from the
legacy ACL system.
A couple places also used authorizer.
This commit also removes another couple of authorizer nil checks that
are no longer necessary.

The constructor for Server is not at all the appropriate place to be setting default
values for a config struct that was passed in.
In production this value is always set from agent/config. In tests we should set the
default in a test helper.
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.

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.

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.

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.

With an optional interface that providers can use to indicate if they
use an intermediate cert in the primary DC.
This removes the need to look up the provider config when renewing the
intermediate.
Replace two methods with a single one that returns the cert. This moves more
of the logic into the single caller (auto-config).
tlsutil.Configurator is widely used. By keeping it smaller and focused only on storing and
returning TLS config, we make the code easier to follow.
These two methods were more related to auto-config than to tlsutil, so reducing the interface
moves the logic closer to the feature that requires it.
This method was accidentally re-introduced in an earlier rebase. It was
removed in ed1082510dc80523b1f2a3a740fa5a13c77594f9 as part of the tproxy work.
There is no interaction between these handlers, so splitting them into separate files
makes it easier to discover the full implementation of each kindHandler.
This commit extracts all the kind-specific logic into handler types, and
keeps the generic parts on the state struct. This change should make it
easier to add new kinds, and see the implementation of each kind more
clearly.

In the absence of stats_tags to handle this pattern, when we pass
"ingress_upstream.$port" as the stat_prefix, Envoy splits up that prefix
and makes the port a part of the metric name.
For example:
- stat_prefix: ingress_upstream.8080
This leads to metric names like envoy_http_8080_no_route. Changing the
stat_prefix to ingress_upstream_80880 yields the expected metric names
such as envoy_http_no_route.
Note that we don't encode the destination's name/ns/dc in this
stat_prefix because for HTTP services ingress gateways use a single
filter chain. Only cluster metrics are available on a per-upstream
basis.
This change makes it so that the stat prefix for terminating gateways
matches that of connect proxies. By using the structure of
"upstream.svc.ns.dc" we can extract labels for the destination service,
namespace, and datacenter.
Updates to a cluster will clear the associated endpoints, and updates to
a listener will clear the associated routes. Update the incremental xDS
logic to account for this implicit cleanup so that we can finish warming
the clusters and listeners.
Fixes#10379
CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.
This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.
Previously we would return an error if duplicate paths were specified.
This could lead to problems in cases where a user has the same path,
say /healthz, on two different ports.
This validation was added to signal a potential misconfiguration.
Instead we will only check for duplicate listener ports, since that is
what would lead to ambiguity issues when generating xDS config.
In the future we could look into using a single listener and creating
distinct filter chains for each path/port.
These two new struct types will allow us to make polymorphic handler for each kind, instad of
having all the logic for each proxy kind on the state struct.
context.Context should never be stored on a struct (as it says in the godoc) because it is easy to
to end up with the wrong context when it is stored.
Also see https://blog.golang.org/context-and-structs
This change is also in preparation for splitting state into kind-specific handlers so that the
implementation of each kind is grouped together.
This field is available in DebugConfig, but that field is not stable and could change at any time.
The consul-k8s needs to be able to detect the primary DC for tests, so adding this field to the
stable part of the API response.
Both NextLink and NextNoBlock had the same logic, with slightly
different return values. By adding a bool return value (similar to map
lookups) we can remove the duplicate method.
The head of the topic buffer was being ignored when creating a snapshot. This commit fixes
the bug by ensuring that the head of the topic buffer is included in the snapshot
before handing it off to the subscription.
When info.Timeout is 0, it should have no timeout. Previously it was using a 0 duration timeout
which caused it to return without waiting.
This bug was masked by using a timeout in the tests. Removing the timeout caused the tests to fail.
This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
We have seen test flakes caused by 'concurrent map read and map write', and the race detector
reports the problem as well (prevent us from running some tests with -race).
The root of the problem is the grpc expects resolvers to be registered at init time
before any requests are made, but we were using a separate resolver for each test.
This commit introduces a resolver registry. The registry is registered as the single
resolver for the consul scheme. Each test uses the Authority section of the target
(instead of the scheme) to identify the resolver that should be used for the test.
The scheme is used for lookup, which is why it can no longer be used as the unique
key.
This allows us to use a lock around the map of resolvers, preventing the data race.

The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.
This refactor is to make it easier to see how serf feature flags are
encoded as serf tags, and where those feature flags are read.
- use constants for both the prefix and feature flag name. A constant
makes it much easier for an IDE to locate the read and write location.
- isolate the feature-flag encoding logic in the metadata package, so
that the feature flag prefix can be unexported. Only expose a function
for encoding the flags into tags. This logic is now next to the logic
which reads the tags.
- remove the duplicate `addEnterpriseSerfTags` functions. Both Client
and Server structs had the same implementation. And neither
implementation needed the method receiver.
The prior solution to call reply.Reset() aged poorly since newer fields
were added to the reply, but not added to Reset() leading serial
blocking query loops on the server to blend replies.
This could manifest as a service-defaults protocol change from
default=>http not reverting back to default after the config entry
reponsible was deleted.
* Save exposed HTTP or GRPC ports to the agent's store
* Add those the health checks API so we can retrieve them from the API
* Change redirect-traffic command to also exclude those ports from inbound traffic redirection when expose.checks is set to true.
TestACLEndpoint_Login_with_TokenLocality was reguardly being reported as failed even though
it was not failing. I took another look and I suspect it is because t.Parllel was being
called in a goroutine.
This would lead to strange behaviour which apparently confused the 'go test' runner.
- return errors in TestAgent.Start so that the retry works correctly
- remove duplicate logging, the error is returned already
- add a missing t.Helper() to retry.Run
- properly set a.Agent to nil so that subsequent retry attempts will actually try to start
Also accept an RPCInfo instead of interface{}. Accepting an interface
lead to a bug where the caller was expecting the arg to be the response
when in fact it was always passed the request. By accepting RPCInfo
it should indicate that this is actually the request value.
One caller of canRetry already passed an RPCInfo, the second handles
the type assertion before calling canRetry.
A recent change in 1.9.x inverted the order of these two lines, which caused the
X-Consul-Effective-Consistency header to be missing for the servie health endpoints
Only default to the user token and agent token for the sync. Change the
exported methods to only return the stored tokens associated with a
specific check or service.
Also fixes a bug with listing kind=mesh config entries. ValidateConfigEntryKind was only being used by
the List endpoint, and was yet another place where we have to enumerate all the kinds.
This commit removes ValidateConfigEntryKind and uses MakeConfigEntry instead. This change removes
the need to maintain two separate functions at the cost of creating an instance of the config entry which will be thrown away immediately.

Previously we would associate the address of a discovery chain target
with the discovery chain's filter chain. This was broken for a few reasons:
- If the upstream is a virtual service, the client proxy has no way of
dialing it because virtual services are not targets of their discovery
chains. The targets are distinct services. This is addressed by watching
the endpoints of all upstream services, not just their discovery chain
targets.
- If multiple discovery chains resolve to the same target, that would
lead to multiple filter chains attempting to match on the target's
virtual IP. This is addressed by only matching on the upstream's virtual
IP.
NOTE: this implementation requires an intention to the redirecting
virtual service and not just to the final destination. This is how
we can know that the virtual service is an upstream to watch.
A later PR will look into traversing discovery chains when computing
upstreams so that intentions are only required to the discovery chain
targets.

* Give descriptive error if auth method not found
Previously during a `consul login -method=blah`, if the auth method was not found, the
error returned would be "ACL not found". This is potentially confusing
because there may be many different ACLs involved in a login: the ACL of
the Consul client, perhaps the binding rule or the auth method.
Now the error will be "auth method blah not found", which is much easier
to debug.
Initially we were loading every potential upstream address into Envoy
and then routing traffic to the logical upstream service. The downside
of this behavior is that traffic meant to go to a specific instance
would be load balanced across ALL instances.
Traffic to specific instance IPs should be forwarded to the original
destination and if it's a destination in the mesh then we should ensure
the appropriate certificates are used.
This PR makes transparent proxying a Kubernetes-only feature for now
since support for other environments requires generating virtual IPs,
and Consul does not do that at the moment.
No config entry needs a Kind field. It is only used to determine the Go type to
target. As we introduce new config entries (like this one) we can remove the kind field
and have the GetKind method return the single supported value.
In this case (similar to proxy-defaults) the Name field is also unnecessary. We always
use the same value. So we can omit the name field entirely.
