Daniel Upton	a31738f76f	proxycfg-glue: server-local implementation of ResolvedServiceConfig ... This is the OSS portion of enterprise PR 2460. Introduces a server-local implementation of the proxycfg.ResolvedServiceConfig interface that sources data from a blocking query against the server's state store. It moves the service config resolution logic into the agent/configentry package so that it can be used in both the RPC handler and data source. I've also done a little re-arranging and adding comments to call out data sources for which there is to be no server-local equivalent.	2 years ago
Daniel Upton	13c04a13af	proxycfg: terminate stream on irrecoverable errors ... This is the OSS portion of enterprise PR 2339. It improves our handling of "irrecoverable" errors in proxycfg data sources. The canonical example of this is what happens when the ACL token presented by Envoy is deleted/revoked. Previously, the stream would get "stuck" until the xDS server re-checked the token (after 5 minutes) and terminated the stream. Materializers would also sit burning resources retrying something that could never succeed. Now, it is possible for data sources to mark errors as "terminal" which causes the xDS stream to be closed immediately. Similarly, the submatview.Store will evict materializers when it observes they have encountered such an error.	2 years ago
Daniel Upton	45886848b4	proxycfg: server-local intention upstreams data source ... This is the OSS portion of enterprise PR 2157. It builds on the local blocking query work in #13438 to implement the proxycfg.IntentionUpstreams interface using server-local data. Also moves the ACL filtering logic from agent/consul into the acl/filter package so that it can be reused here.	2 years ago
