Note that this does NOT upgrade to xDS v3. That will come in a future PR.
Additionally:
- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.
Fixes#8425
To fix failing integration tests. The latest version (`1.7.4.0-r0`)
appears to not be catting all the bytes, so the expected metrics are
missing in the output.
This PR updates the tags that we generate for Envoy stats.
Several of these come with breaking changes, since we can't keep two stats prefixes for a filter.
* ci: stop building darwin/386 binaries
Go 1.15 drops support for 32-bit binaries on Darwin https://golang.org/doc/go1.15#darwin
* tls: ConnectionState::NegotiatedProtocolIsMutual is deprecated in Go 1.15, this value is always true
* correct error messages that changed slightly
* Completely regenerate some TLS test data

This has the biggest impact on enterprise test cases that use namespaced
registrations, which prior to this change sometimes failed the initial
registration because the namespace was not yet created.
Added a new option `ui_config.metrics_proxy.path_allowlist`. This defaults to `["/api/v1/query", "/api/v1/query_range"]` when the metrics provider is set to `prometheus`.
Requests that do not use one of the allow-listed paths (via exact match) get a 403 Forbidden response instead.
The key thing here is to use `curl --no-keepalive` so that envoy
pre-1.15 tests will reliably use the latest listener every time.
Extra:
- Switched away from editing line-item intentions the legacy way.
- Removed some teardown scripts, as we don't share anything between cases anyway
- Removed unnecessary use of `run` in some places.
There is a delay between an intentions change being made, and it being
reflected in the Envoy runtime configuration. Now that the enforcement
happens inside of Envoy instead of over in the agent, our tests need to
explicitly wait until the xDS reconfiguration is complete before
attempting to assert intentions worked.
Also remove a few double retry loops.
This speeds up individual envoy integration test runs from ~23m to ~14m.
It's also a pre-req for possibly switching to doing the tests entirely within Go (no shell-outs).
Extend Consul’s intentions model to allow for request-based access control enforcement for HTTP-like protocols in addition to the existing connection-based enforcement for unspecified protocols (e.g. tcp).
Related changes:
- hard-fail the xDS connection attempt if the envoy version is known to be too old to be supported
- remove the RouterMatchSafeRegex proxy feature since all supported envoy versions have it
- stop using --max-obj-name-len (due to: envoyproxy/envoy#11740)
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.
Previously, we did not require the 'service-name.*' host header value
when on a single http service was exposed. However, this allows a user
to get into a situation where, if they add another service to the
listener, suddenly the previous service's traffic might not be routed
correctly. Thus, we always require the Host header, even if there is
only 1 service.
Also, we add the make the default domain matching more restrictive by
matching "service-name.ingress.*" by default. This lines up better with
the namespace case and more accurately matches the Consul DNS value we
expect people to use in this case.
The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option.
If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS.
Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.
