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.
- The TestNodeService helper created services with the fixed name "web",
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

A couple places also used authorizer.

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

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.

removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.

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.
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.

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.
* fix tests to use a dummy nodeName and not fail when hostname is not a valid nodeName
* remove conditional testing
* add test when node name is invalid
* debug: remove the CLI check for debug_enabled
The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.
Also:
- fix the API client to return errors on non-200 status codes for debug
endpoints
- improve the failure messages when pprof data can not be collected

* remove parallel test runs
parallel runs create a race condition that fail the debug tests
* Add changelog

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.
