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.
- 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
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.

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`.
