Previously this happened to be using the method on the Server/Client that was meant to allow the ACLResolver to locally resolve tokens. On Servers that had tokens (primary or secondary dc + token replication) this function would lookup the token from raft and return the ACLIdentity. On clients this was always a noop. We inadvertently used this function instead of creating a new one when we added logging accessor ids for permission denied RPC requests.
With this commit, a new method is used for resolving the identity properly via the ACLResolver which may still resolve locally in the case of being on a server with tokens but also supports remote token resolution.
* Return early from updateGatewayServices if nothing to update
Previously, we returned an empty slice of gatewayServices, which caused
us to accidentally delete everything in the memdb table
* PR comment and better formatting
go test will only run tests in parallel within a single package. In this case the package test run time is exactly the same with or without t.Parallel() (~0.7s).
In generally we should avoid t.Parallel() as it causes a number of problems with `go test` not reporting failure messages correctly. I encountered one of these problems, which is what prompted this change. Since `t.Parallel` is not providing any benefit in this package, this commit removes it.
The change was automated with:
git grep -l 't.Parallel' | xargs sed -i -e '/t.Parallel/d'
This is useful when updating an config entry with no services, and the
expected behavior is that envoy closes all listeners and clusters.
We also allow empty routes because ingress gateways name route
configurations based on the port of the listener, so it is important we
remove any stale routes. Then, if a new listener with an old port is
added, we will not have to deal with stale routes hanging around routing
to the wrong place.
Endpoints are associated with clusters, and thus by deleting the
clusters we don't have to care about sending empty endpoint responses.
- Use correct enterprise metadata for finding config entry
- nil out cancel functions on config snapshot copy
- Look at HostsSet when checking validity
We require any non-wildcard services to match the protocol defined in
the listener on write, so that we can maintain a consistent experience
through ingress gateways. This also helps guard against accidental
misconfiguration by a user.
- Update tests that require an updated protocol for ingress gateways
We can only allow host names that are valid domain names because we put
these hosts into a DNSSAN. In addition, we validate that the wildcard
specifier '*' is only present as the leftmost label to allow for a
wildcard DNSSAN and associated wildcard Host routing in the ingress
gateway proxy.
This now requires some type of protocol setting in ingress gateway tests
to ensure the services are not filtered out.
- small refactor to add a max(x, y) function
- Use internal configEntryTxn function and add MaxUint64 to lib
- Validate that this cannot be set on a 'tcp' listener nor on a wildcard
service.
- Add Hosts field to api and test in consul config write CLI
- xds: Configure envoy with user-provided hosts from ingress gateways
This commit adds the necessary changes to allow an ingress gateway to
route traffic from a single defined port to multiple different upstream
services in the Consul mesh.
To do this, we now require all HTTP requests coming into the ingress
gateway to specify a Host header that matches "<service-name>.*" in
order to correctly route traffic to the correct service.
- Differentiate multiple listener's route names by port
- Adds a case in xds for allowing default discovery chains to create a
route configuration when on an ingress gateway. This allows default
services to easily use host header routing
- ingress-gateways have a single route config for each listener
that utilizes domain matching to route to different services.
