Fix configuration merging for implicit tproxy upstreams.
Change the merging logic so that the wildcard upstream has correct proxy-defaults
and service-defaults values combined into it. It did not previously merge all fields,
and the wildcard upstream did not exist unless service-defaults existed (it ignored
proxy-defaults, essentially).
Change the way we fetch upstream configuration in the xDS layer so that it falls back
to the wildcard when no matching upstream is found. This is what allows implicit peer
upstreams to have the correct "merged" config.
Change proxycfg to always watch local mesh gateway endpoints whenever a peer upstream
is found. This simplifies the logic so that we do not have to inspect the "merged"
configuration on peer upstreams to extract the mesh gateway mode.
Previously, we'd begin a session with the xDS concurrency limiter
regardless of whether the proxy was registered in the catalog or in
the server's local agent state.
This caused problems for users who run `consul connect envoy` directly
against a server rather than a client agent, as the server's locally
registered proxies wouldn't be included in the limiter's capacity.
Now, the `ConfigSource` is responsible for beginning the session and we
only do so for services in the catalog.
Fixes: https://github.com/hashicorp/consul/issues/15753
Enforce lowercase peer names.
Prior to this change peer names could be mixed case.
This can cause issues, as peer names are used as DNS labels
in various locations. It also caused issues with envoy
configuration.
When using SNI in Terminating Gateway, Consul configures envoy to
have strict SAN matching. This requires all external services to
have SANs in their certificates and not having it will throw
CERTIFICATE_VERIFY_FAILED error.
- remove dep on consul main module
- use 'consul tls' subcommands instead of tlsutil
- use direct json config construction instead of agent/config structs
- merge libcluster and libagent packages together
- more widely use BuildContext
- get the OSS/ENT runner stuff working properly
- reduce some flakiness
- fix some correctness related to http/https API

* Protobuf Modernization
Remove direct usage of golang/protobuf in favor of google.golang.org/protobuf
Marshallers (protobuf and json) needed some changes to account for different APIs.
Moved to using the google.golang.org/protobuf/types/known/* for the well known types including replacing some custom Struct manipulation with whats available in the structpb well known type package.
This also updates our devtools script to install protoc-gen-go from the right location so that files it generates conform to the correct interfaces.
* Fix go-mod-tidy make target to work on all modules
- Fixes a panic when Operation.SourceAddr is nil (internal net/rpc calls)
- Adds proper HTTP response codes (429 and 503) for rate limit errors
- Makes the error messages clearer
- Enables automatic retries for rate-limit errors in the net/rpc stack
Fix issue where TLS configuration was ignored for unix sockets in consul connect envoy.
Disable xds check on bootstrap mode and change check to warn only.
* inject logger and create logdrop sink
* init sink with an empty struct instead of nil
* wrap a logger instead of a sink and add a discard logger to avoid double logging
* fix compile errors
* fix linter errors
* Fix bug where log arguments aren't properly formatted
* Move log sink construction outside of handler
* Add prometheus definition and docs for log drop counter

Fixes a bug introduced by #15346 where we'd always require an ACL
token even if ACLs were disabled because we were erroneously
treating `nil` identity as anonymous.
This is the OSS portion of enterprise PR 3822.
Adds a custom gRPC balancer that replicates the router's server cycling
behavior. Also enables automatic retries for RESOURCE_EXHAUSTED errors,
which we now get for free.
* Update api gateway version to latest
* Update website/content/docs/api-gateway/install.mdx
* update to latest apigw version 0.5.1
* update consul and helm version
* Refactoring the peering integ test to accommodate coming changes of other upgrade scenarios.
- Add a utils package under test that contains methods to set up various test scenarios.
- Deduplication: have a single CreatingPeeringClusterAndSetup replace
CreatingAcceptingClusterAndSetup and CreateDialingClusterAndSetup.
- Separate peering cluster creation and server registration.
* Apply suggestions from code review

Adds automation for generating the map of `gRPC Method Name → Rate Limit Type`
used by the middleware introduced in #15550, and will ensure we don't forget
to add new endpoints.
Engineers must annotate their RPCs in the proto file like so:
```
rpc Foo(FooRequest) returns (FooResponse) {
option (consul.internal.ratelimit.spec) = {
operation_type: READ,
};
}
```
When they run `make proto` a protoc plugin `protoc-gen-consul-rate-limit` will
be installed that writes rate-limit specs as a JSON array to a file called
`.ratelimit.tmp` (one per protobuf package/directory).
After running Buf, `make proto` will execute a post-process script that will
ingest all of the `.ratelimit.tmp` files and generate a Go file containing the
mappings in the `agent/grpc-middleware` package. In the enterprise repository,
it will write an additional file with the enterprise-only endpoints.
If an engineer forgets to add the annotation to a new RPC, the plugin will
return an error like so:
```
RPC Foo is missing rate-limit specification, fix it with:
import "proto-public/annotations/ratelimit/ratelimit.proto";
service Bar {
rpc Foo(...) returns (...) {
option (hashicorp.consul.internal.ratelimit.spec) = {
operation_type: OPERATION_READ | OPERATION_WRITE | OPERATION_EXEMPT,
};
}
}
```
In the future, this annotation can be extended to support rate-limit
category (e.g. KV vs Catalog) and to determine the retry policy.
Previously, these endpoints required `service:write` permission on _any_
service as a sort of proxy for "is the caller allowed to participate in
the mesh?".
Now, they're called as part of the process of establishing a server
connection by any consumer of the consul-server-connection-manager
library, which will include non-mesh workloads (e.g. Consul KV as a
storage backend for Vault) as well as ancillary components such as
consul-k8s' acl-init process, which likely won't have `service:write`
permission.
So this commit relaxes those requirements to accept *any* valid ACL token
on the following gRPC endpoints:
- `hashicorp.consul.dataplane.DataplaneService/GetSupportedDataplaneFeatures`
- `hashicorp.consul.serverdiscovery.ServerDiscoveryService/WatchServers`
- `hashicorp.consul.connectca.ConnectCAService/WatchRoots`
Fix agent cache incorrectly notifying unchanged protobufs.
This change fixes a situation where the protobuf private fields
would be read by reflect.DeepEqual() and indicate data was modified.
This resulted in change notifications being fired every time, which
could cause performance problems in proxycfg.
