This is instead of having the AutoConfigBackend interface provide functions for retrieving them.
NOTE: the config is not reloadable. For now this is fine as we don’t look at any reloadable fields. If that changes then we should provide a way to make it reloadable.
A port can be sent in the Host header as defined in the HTTP RFC, so we
take any hosts that we want to match traffic to and also add another
host with the listener port added.
Also fix an issue with envoy integration tests not running the
case-ingress-gateway-tls test.
In all cases (oss/ent, client/server) this method was returning a value from config. Since the
value is consistent, it doesn't need to be part of the delegate interface.
Fixes#7527
I want to highlight this and explain what I think the implications are and make sure we are aware:
* `HTTPConnStateFunc` closes the connection when it is beyond the limit. `Close` does not block.
* `HTTPConnStateFuncWithDefault429Handler(10 * time.Millisecond)` blocks until the following is done (worst case):
1) `conn.SetDeadline(10*time.Millisecond)` so that
2) `conn.Write(429error)` is guaranteed to timeout after 10ms, so that the http 429 can be written and
3) `conn.Close` can happen
The implication of this change is that accepting any new connection is worst case delayed by 10ms. But only after a client reached the limit already.
The embedded HTTPServer struct is not used by the large HTTPServer
struct. It is used by tests and the agent. This change is a small first
step in the process of removing that field.
The eventual goal is to reduce the scope of HTTPServer making it easier
to test, and split into separate packages.
A query made with AllowNotModifiedResponse and a MinIndex, where the
result has the same Index as MinIndex, will return an empty response
with QueryMeta.NotModified set to true.

Also fix a bug where Consul could segfault if TLS was enabled but no client certificate was provided. How no one has reported this as a problem I am not sure.
The initial auto encrypt CSR wasn’t containing the user supplied IP and DNS SANs. This fixes that. Also We were configuring a default :: IP SAN. This should be ::1 instead and was fixed.
Highlights:
- add new endpoint to query for intentions by exact match
- using this endpoint from the CLI instead of the dump+filter approach
- enforcing that OSS can only read/write intentions with a SourceNS or
DestinationNS field of "default".
- preexisting OSS intentions with now-invalid namespace fields will
delete those intentions on initial election or for wildcard namespaces
an attempt will be made to downgrade them to "default" unless one
exists.
- also allow the '-namespace' CLI arg on all of the intention subcommands
- update lots of docs
Split up unused key validation in config entry decode for oss/ent.
This is needed so that we can return an informative error in OSS if namespaces are provided.
Previously, we were only returning a single ListenerPort for a single
service. However, we actually allow a single service to be serviced over
multiple ports, as well as allow users to define what hostnames they
expect their services to be contacted over. When no hosts are defined,
we return the default ingress domain for any configured DNS domain.
To show this in the UI, we modify the gateway-services-nodes API to
return a GatewayConfig.Addresses field, which is a list of addresses
over which the specific service can be contacted.
This is in its own separate package so that it will be a separate test binary that runs thus isolating the go runtime from other tests and allowing accurate go routine leak checking.
This test would ideally use goleak.VerifyTestMain but that will fail 100% of the time due to some architectural things (blocking queries and net/rpc uncancellability).
This test is not comprehensive. We should enable/exercise more features and more cluster configurations. However its a start.
The old test case was a very specific regresion test for a case that is no longer possible.
Replaced with a new test that checks the default coordinate is returned.
We needed to pass a cancellable context into the limiter.Wait instead of context.Background. So I made the func take a context instead of a chan as most places were just passing through a Done chan from a context anyways.
Fix go routine leak in the gateway locator
This will allow to increase cache value when DC is not valid (aka
return SOA to avoid too many consecutive requests) and will
distinguish DC being temporarily not available from DC not existing.
Implements https://github.com/hashicorp/consul/issues/8102
On the servers they must have a certificate.
On the clients they just have to set verify_outgoing to true to attempt TLS connections for RPCs.
Eventually we may relax these restrictions but right now all of the settings we push down (acl tokens, acl related settings, certificates, gossip key) are sensitive and shouldn’t be transmitted over an unencrypted connection. Our guides and docs should recoommend verify_server_hostname on the clients as well.
Another reason to do this is weird things happen when making an insecure RPC when TLS is not enabled. Basically it tries TLS anyways. We should probably fix that to make it clearer what is going on.
