* TestServer_hcpManager

Fix so that link API values are used over env vars
When a link is created via the API, those values should take precedence over
the values set by environment variables. This change loads all the env vars
initially as part of the config builder rather than on demand.
* Check for ACL write permissions on write
Link eventually will be creating a token, so require acl:write.
* Convert Run to Start, only allow to start once
* Always initialize HCP components at startup
* Support for updating config and client
* Pass HCP manager to controller
* Start HCP manager in link resource
Start as part of link creation rather than always starting. Update
the HCP manager with values from the link before starting as well.
* Fix metrics sink leaked goroutine
* Remove the hardcoded disabled hostname prefix
The HCP metrics sink will always be enabled, so the length of sinks will
always be greater than zero. This also means that we will also always
default to prefixing metrics with the hostname, which is what our
documentation states is the expected behavior anyway.
* Add changelog
* Check and set running status in one method
* Check for primary datacenter, add back test
* Clarify merge reasoning, fix timing issue in test
* Add comment about controller placement

Ultimately we will have to rectify wan federation with v2 catalog adjacent
experiments, but for now blanket prevent usage of the resource-apis,
v2dns, and v2tenancy experiments in secondary datacenters.

The Initializer adds support for running any required initialization
steps when the controller is first started.

Prior to the introduction of this configuration, grpc keepalive messages were
sent after 2 hours of inactivity on the stream. This posed issues in various
scenarios where the server-side xds connection balancing was unaware that envoy
instances were uncleanly killed / force-closed, since the connections would
only be cleaned up after ~5 minutes of TCP timeouts occurred. Setting this
config to a 30 second interval with a 20 second timeout ensures that at most,
it should take up to 50 seconds for a dead xds connection to be closed.

* Persist HCP management token from server config
We want to move away from injecting an initial management token into
Consul clusters linked to HCP. The reasoning is that by using a separate
class of token we can have more flexibility in terms of allowing HCP's
token to co-exist with the user's management token.
Down the line we can also more easily adjust the permissions attached to
HCP's token to limit it's scope.
With these changes, the cloud management token is like the initial
management token in that iit has the same global management policy and
if it is created it effectively bootstraps the ACL system.
* Update SDK and mock HCP server
The HCP management token will now be sent in a special field rather than
as Consul's "initial management" token configuration.
This commit also updates the mock HCP server to more accurately reflect
the behavior of the CCM backend.
* Refactor HCP bootstrapping logic and add tests
We want to allow users to link Consul clusters that already exist to
HCP. Existing clusters need care when bootstrapped by HCP, since we do
not want to do things like change ACL/TLS settings for a running
cluster.
Additional changes:
* Deconstruct MaybeBootstrap so that it can be tested. The HCP Go SDK
requires HTTPS to fetch a token from the Auth URL, even if the backend
server is mocked. By pulling the hcp.Client creation out we can modify
its TLS configuration in tests while keeping the secure behavior in
production code.
* Add light validation for data received/loaded.
* Sanitize initial_management token from received config, since HCP will
only ever use the CloudConfig.MangementToken.
* Add changelog entry
Receiving an "acl not found" error from an RPC in the agent cache and the
streaming/event components will cause any request loops to cease under the
assumption that they will never work again if the token was destroyed. This
prevents log spam (#14144, #9738).
Unfortunately due to things like:
- authz requests going to stale servers that may not have witnessed the token
creation yet
- authz requests in a secondary datacenter happening before the tokens get
replicated to that datacenter
- authz requests from a primary TO a secondary datacenter happening before the
tokens get replicated to that datacenter
The caller will get an "acl not found" *before* the token exists, rather than
just after. The machinery added above in the linked PRs will kick in and
prevent the request loop from looping around again once the tokens actually
exist.
For `consul-dataplane` usages, where xDS is served by the Consul servers
rather than the clients ultimately this is not a problem because in that
scenario the `agent/proxycfg` machinery is on-demand and launched by a new xDS
stream needing data for a specific service in the catalog. If the watching
goroutines are terminated it ripples down and terminates the xDS stream, which
CDP will eventually re-establish and restart everything.
For Consul client usages, the `agent/proxycfg` machinery is ahead-of-time
launched at service registration time (called "local" in some of the proxycfg
machinery) so when the xDS stream comes in the data is already ready to go. If
the watching goroutines terminate it should terminate the xDS stream, but
there's no mechanism to re-spawn the watching goroutines. If the xDS stream
reconnects it will see no `ConfigSnapshot` and will not get one again until
the client agent is restarted, or the service is re-registered with something
changed in it.
This PR fixes a few things in the machinery:
- there was an inadvertent deadlock in fetching snapshot from the proxycfg
machinery by xDS, such that when the watching goroutine terminated the
snapshots would never be fetched. This caused some of the xDS machinery to
get indefinitely paused and not finish the teardown properly.
- Every 30s we now attempt to re-insert all locally registered services into
the proxycfg machinery.
- When services are re-inserted into the proxycfg machinery we special case
"dead" ones such that we unilaterally replace them rather that doing that
conditionally.
Protobuf Refactoring for Multi-Module Cleanliness
This commit includes the following:
Moves all packages that were within proto/ to proto/private
Rewrites imports to account for the packages being moved
Adds in buf.work.yaml to enable buf workspaces
Names the proto-public buf module so that we can override the Go package imports within proto/buf.yaml
Bumps the buf version dependency to 1.14.0 (I was trying out the version to see if it would get around an issue - it didn't but it also doesn't break things and it seemed best to keep up with the toolchain changes)
Why:
In the future we will need to consume other protobuf dependencies such as the Google HTTP annotations for openapi generation or grpc-gateway usage.
There were some recent changes to have our own ratelimiting annotations.
The two combined were not working when I was trying to use them together (attempting to rebase another branch)
Buf workspaces should be the solution to the problem
Buf workspaces means that each module will have generated Go code that embeds proto file names relative to the proto dir and not the top level repo root.
This resulted in proto file name conflicts in the Go global protobuf type registry.
The solution to that was to add in a private/ directory into the path within the proto/ directory.
That then required rewriting all the imports.
Is this safe?
AFAICT yes
The gRPC wire protocol doesn't seem to care about the proto file names (although the Go grpc code does tack on the proto file name as Metadata in the ServiceDesc)
Other than imports, there were no changes to any generated code as a result of this.
