Dan Upton	d7f8a8e4ef	proxycfg: remove dependency on `cache.UpdateEvent` (#13144) ... OSS portion of enterprise PR 1857. This removes (most) references to the `cache.UpdateEvent` type in the `proxycfg` package. As we're going to be direct usage of the agent cache with interfaces that can be satisfied by alternative server-local datasources, it doesn't make sense to depend on this type everywhere anymore (particularly on the `state.ch` channel). We also plan to extract `proxycfg` out of Consul into a shared library in the future, which would require removing this dependency. Aside from a fairly rote find-and-replace, the main change is that the `cache.Cache` and `health.Client` types now accept a callback function parameter, rather than a `chan<- cache.UpdateEvents`. This allows us to do the type conversion without running another goroutine.	3 years ago

R.B. Boyer	2a56e0055b	proxycfg: change how various proxycfg test helpers for making ConfigSnapshot copies works to be more correct and less error prone (#12531) ... Prior to this PR for the envoy xDS golden tests in the agent/xds package we were hand-creating a proxycfg.ConfigSnapshot structure in the proper format for input to the xDS generator. Over time this intermediate structure has gotten trickier to build correctly for the various tests. This PR proposes to switch to using the existing mechanism for turning a structs.NodeService and a sequence of cache.UpdateEvent copies into a proxycfg.ConfigSnapshot, as that is less error prone to construct and aligns more with how the data arrives. NOTE: almost all of this is in test-related code. I tried super hard to craft correct event inputs to get the golden files to be the same, or similar enough after construction to feel ok that i recreated the spirit of the original test cases.	3 years ago
freddygv	ceb52d649a	Account for upstream targets in another DC. ... Transparent proxies typically cannot dial upstreams in remote datacenters. However, if their upstream configures a redirect to a remote DC then the upstream targets will be in another datacenter. In that sort of case we should use the WAN address for the passthrough.	3 years ago
freddygv	cbea3d203c	Fix race of upstreams with same passthrough ip ... Due to timing, a transparent proxy could have two upstreams to dial directly with the same address. For example: - The orders service can dial upstreams shipping and payment directly. - An instance of shipping at address 10.0.0.1 is deregistered. - Payments is scaled up and scheduled to have address 10.0.0.1. - The orders service receives the event for the new payments instance before seeing the deregistration for the shipping instance. At this point two upstreams have the same passthrough address and Envoy will reject the listener configuration. To disambiguate this commit considers the Raft index when storing passthrough addresses. In the example above, 10.0.0.1 would only be associated with the newer payments service instance.	3 years ago
freddygv	659ebc05a9	Ensure passthrough addresses get cleaned up ... Transparent proxies can set up filter chains that allow direct connections to upstream service instances. Services that can be dialed directly are stored in the PassthroughUpstreams map of the proxycfg snapshot. Previously these addresses were not being cleaned up based on new service health data. The list of addresses associated with an upstream service would only ever grow. As services scale up and down, eventually they will have instances assigned to an IP that was previously assigned to a different service. When IP addresses are duplicated across filter chain match rules the listener config will be rejected by Envoy. This commit updates the proxycfg snapshot management so that passthrough addresses can get cleaned up when no longer associated with a given upstream. There is still the possibility of a race condition here where due to timing an address is shared between multiple passthrough upstreams. That concern is mitigated by #12195, but will be further addressed in a follow-up.	3 years ago

R.B. Boyer	424f3cdd2c	proxycfg: introduce explicit UpstreamID in lieu of bare string (#12125) ... The gist here is that now we use a value-type struct proxycfg.UpstreamID as the map key in ConfigSnapshot maps where we used to use "upstream id-ish" strings. These are internal only and used just for bidirectional trips through the agent cache keyspace (like the discovery chain target struct). For the few places where the upstream id needs to be projected into xDS, that's what (proxycfg.UpstreamID).EnvoyID() is for. This lets us ALWAYS inject the partition and namespace into these things without making stuff like the golden testdata diverge.	3 years ago

Freddy	00b5b0a0a2	Update filter chain creation for sidecar/ingress listeners (#11245) ... The duo of `makeUpstreamFilterChainForDiscoveryChain` and `makeListenerForDiscoveryChain` were really hard to reason about, and led to concealing a bug in their branching logic. There were several issues here: - They tried to accomplish too much: determining filter name, cluster name, and whether RDS should be used. - They embedded logic to handle significantly different kinds of upstream listeners (passthrough, prepared query, typical services, and catch-all) - They needed to coalesce different data sources (Upstream and CompiledDiscoveryChain) Rather than handling all of those tasks inside of these functions, this PR pulls out the RDS/clusterName/filterName logic. This refactor also fixed a bug with the handling of [UpstreamDefaults](https://www.consul.io/docs/connect/config-entries/service-defaults#defaults). These defaults get stored as UpstreamConfig in the proxy snapshot with a DestinationName of "*", since they apply to all upstreams. However, this wildcard destination name must not be used when creating the name of the associated upstream cluster. The coalescing logic in the original functions here was in some situations creating clusters with a `*.` prefix, which is not a valid destination.	3 years ago
Daniel Upton	50a1f20ff9	xds: prefer fed state gateway definitions if they're fresher (#11522) ... Fixes an issue described in #10132, where if two DCs are WAN federated over mesh gateways, and the gateway in the non-primary DC is terminated and receives a new IP address (as is commonly the case when running them on ephemeral compute instances) the primary DC is unable to re-establish its connection until the agent running on its own gateway is restarted. This was happening because we always preferred gateways discovered by the `Internal.ServiceDump` RPC (which would fail because there's no way to dial the remote DC) over those discovered in the federation state, which is replicated as long as the primary DC's gateway is reachable.	3 years ago
