Derek Menteer	0ac8ae6c3b	Fix xDS deadlock due to syncLoop termination. (#20867) ... * Fix xDS deadlock due to syncLoop termination. This fixes an issue where agentless xDS streams can deadlock permanently until a server is restarted. When this issue occurs, no new proxies are able to successfully connect to the server. Effectively, the trigger for this deadlock stems from the following return statement: https://github.com/hashicorp/consul/blob/v1.18.0/agent/proxycfg-sources/catalog/config_source.go#L199-L202 When this happens, the entire `syncLoop()` terminates and stops consuming from the following channel: https://github.com/hashicorp/consul/blob/v1.18.0/agent/proxycfg-sources/catalog/config_source.go#L182-L192 Which results in the `ConfigSource.cleanup()` function never receiving a response and holding a mutex indefinitely: https://github.com/hashicorp/consul/blob/v1.18.0/agent/proxycfg-sources/catalog/config_source.go#L241-L247 Because this mutex is shared, it effectively deadlocks the server's ability to process new xDS streams. ---- The fix to this issue involves removing the `chan chan struct{}` used like an RPC-over-channels pattern and replacing it with two distinct channels: + `stopSyncLoopCh` - indicates that the `syncLoop()` should terminate soon. + `syncLoopDoneCh` - indicates that the `syncLoop()` has terminated. Splitting these two concepts out and deferring a `close(syncLoopDoneCh)` in the `syncLoop()` function ensures that the deadlock above should no longer occur. We also now evict xDS connections of all proxies for the corresponding `syncLoop()` whenever it encounters an irrecoverable error. This is done by hoisting the new `syncLoopDoneCh` upwards so that it's visible to the xDS delta processing. Prior to this fix, the behavior was to simply orphan them so they would never receive catalog-registration or service-defaults updates. * Add changelog.	9 months ago

Nitya Dhanushkodi	8728a4496c	troubleshoot: service to service validation (#16096) ... * Add Tproxy support to Envoy Extensions (this is needed for service to service validation) * Add validation for Envoy configuration for an upstream service * Use both /config_dump and /cluster to validate Envoy configuration This is because of a bug in Envoy where the EndpointsConfigDump does not include a cluster_name, making it impossible to match an endpoint to verify it exists. This removes endpoints support for builtin extensions since only the validate plugin was using it, and it is no longer used. It also removes test cases for endpoint validation. Endpoints validation now only occurs in the top level test from config_dump and clusters json files. Co-authored-by: Eric <eric@haberkorn.co>	2 years ago
Dan Upton	7a55de375c	xds: don't attempt to load-balance sessions for local proxies (#15789) ... 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	2 years ago

Dan Upton	1c2c975b0b	xDS Load Balancing (#14397) ... Prior to #13244, connect proxies and gateways could only be configured by an xDS session served by the local client agent. In an upcoming release, it will be possible to deploy a Consul service mesh without client agents. In this model, xDS sessions will be handled by the servers themselves, which necessitates load-balancing to prevent a single server from receiving a disproportionate amount of load and becoming overwhelmed. This introduces a simple form of load-balancing where Consul will attempt to achieve an even spread of load (xDS sessions) between all healthy servers. It does so by implementing a concurrent session limiter (limiter.SessionLimiter) and adjusting the limit according to autopilot state and proxy service registrations in the catalog. If a server is already over capacity (i.e. the session limit is lowered), Consul will begin draining sessions to rebalance the load. This will result in the client receiving a `RESOURCE_EXHAUSTED` status code. It is the client's responsibility to observe this response and reconnect to a different server. Users of the gRPC client connection brokered by the consul-server-connection-manager library will get this for free. The rate at which Consul will drain sessions to rebalance load is scaled dynamically based on the number of proxies in the catalog.	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
Dan Upton	b9e525d689	grpc: rename public/private directories to external/internal (#13721) ... Previously, public referred to gRPC services that are both exposed on the dedicated gRPC port and have their definitions in the proto-public directory (so were considered usable by 3rd parties). Whereas private referred to services on the multiplexed server port that are only usable by agents and other servers. Now, we're splitting these definitions, such that external/internal refers to the port and public/private refers to whether they can be used by 3rd parties. This is necessary because the peering replication API needs to be exposed on the dedicated port, but is not (yet) suitable for use by 3rd parties.	2 years ago
Dan Upton	b168424398	xds: remove HTTPCheckFetcher dependency (#13366) ... This is the OSS portion of enterprise PR 1994 Rather than directly interrogating the agent-local state for HTTP checks using the `HTTPCheckFetcher` interface, we now rely on the config snapshot containing the checks. This reduces the number of changes required to support server xDS sessions. It's not clear why the fetching approach was introduced in 931d167ebb.	3 years ago
Dan Upton	2427e38839	Enable servers to configure arbitrary proxies from the catalog (#13244) ... OSS port of enterprise PR 1822 Includes the necessary changes to the `proxycfg` and `xds` packages to enable Consul servers to configure arbitrary proxies using catalog data. Broadly, `proxycfg.Manager` now has public methods for registering, deregistering, and listing registered proxies — the existing local agent state-sync behavior has been moved into a separate component that makes use of these methods. When an xDS session is started for a proxy service in the catalog, a goroutine will be spawned to watch the service in the server's state store and re-register it with the `proxycfg.Manager` whenever it is updated (and clean it up when the client goes away).	3 years ago

R.B. Boyer	b2d17ac448	xds: fix representation of incremental xDS subscriptions (#10987) ... Fixes #10563 The `resourceVersion` map was doing two jobs prior to this PR. The first job was to track what version of every resource we know envoy currently has. The second was to track subscriptions to those resources (by way of the empty string for a version). This mostly works out fine, but occasionally leads to consul removing a resource and accidentally (effectively) unsubscribing at the same time. The fix separates these two jobs. When all of the resources for a subscription are removed we continue to track the subscription until envoy explicitly unsubscribes	3 years ago

R.B. Boyer	71d45a3460	Support Incremental xDS mode (#9855) ... This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged. Union of all commit messages follows to give an overarching summary: xds: exclusively support incremental xDS when using xDS v3 Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail. Work around a strange older envoy behavior involving empty CDS responses over incremental xDS. xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead. Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client. xds: pull out checkStreamACLs method in advance of a later commit xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty. This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10. xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time	4 years ago
