Daniel Upton	f8dba7e9ac	proxycfg-glue: server-local implementation of InternalServiceDump ... This is the OSS portion of enterprise PR 2489. This PR introduces a server-local implementation of the proxycfg.InternalServiceDump interface that sources data from a blocking query against the server's state store. For simplicity, it only implements the subset of the Internal.ServiceDump RPC handler actually used by proxycfg - as such the result type has been changed to IndexedCheckServiceNodes to avoid confusion.	2 years ago

R.B. Boyer	f557509e58	xds: allow for peered upstreams to use tagged addresses that are hostnames (#13422) ... Mesh gateways can use hostnames in their tagged addresses (#7999). This is useful if you were to expose a mesh gateway using a cloud networking load balancer appliance that gives you a DNS name but no reliable static IPs. Envoy cannot accept hostnames via EDS and those must be configured using CDS. There was already logic when configuring gateways in other locations in the code, but given the illusions in play for peering the downstream of a peered service wasn't aware that it should be doing that. Also: - ensuring that we always try to use wan-like addresses to cross peer boundaries.	2 years ago

Dan Upton	adeabed126	proxycfg: replace direct agent cache usage with interfaces (#13320) ... This is the OSS portion of enterprise PRs 1904, 1905, 1906, 1907, 1949, and 1971. It replaces the proxycfg manager's direct dependency on the agent cache with interfaces that will be implemented differently when serving xDS sessions from a Consul server.	3 years ago
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	e79ce8ab03	xds: adding control of the mesh-wide min/max TLS versions and cipher suites from the mesh config entry (#12601) ... - `tls.incoming`: applies to the inbound mTLS targeting the public listener on `connect-proxy` and `terminating-gateway` envoy instances - `tls.outgoing`: applies to the outbound mTLS dialing upstreams from `connect-proxy` and `ingress-gateway` envoy instances Fixes #11966	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
