Daniel Upton	37ccbd2826	proxycfg: server-local intentions data source ... This is the OSS portion of enterprise PR 2141. This commit provides a server-local implementation of the `proxycfg.Intentions` interface that sources data from streaming events. It adds events for the `service-intentions` config entry type, and then consumes event streams (via materialized views) for the service's explicit intentions and any applicable wildcard intentions, merging them into a single list of intentions. An alternative approach I considered was to consume _all_ intention events (via `SubjectWildcard`) and filter out the irrelevant ones. This would admittedly remove some complexity in the `agent/proxycfg-glue` package but at the expense of considerable overhead from waking potentially many thousands of connect proxies every time any intention is updated.	2 years ago
R.B. Boyer	201d1458c3	xds: mesh gateways now have their own leaf certificate when involved in a peering (#13460) ... This is only configured in xDS when a service with an L7 protocol is exported. They also load any relevant trust bundles for the peered services to eventually use for L7 SPIFFE validation during mTLS termination.	2 years ago
R.B. Boyer	ab758b7b32	peering: allow mesh gateways to proxy L4 peered traffic (#13339) ... Mesh gateways will now enable tcp connections with SNI names including peering information so that those connections may be proxied. Note: this does not change the callers to use these mesh gateways.	3 years ago
Freddy	a09c776645	Update public listener with SPIFFE Validator ... Envoy's SPIFFE certificate validation extension allows for us to validate against different root certificates depending on the trust domain of the dialing proxy. If there are any trust bundles from peers in the config snapshot then we use the SPIFFE validator as the validation context, rather than the usual TrustedCA. The injected validation config includes the local root certificates as well.	3 years ago
Freddy	74ca6406ea	Configure upstream TLS context with peer root certs (#13321) ... For mTLS to work between two proxies in peered clusters with different root CAs, proxies need to configure their outbound listener to use different root certificates for validation. Up until peering was introduced proxies would only ever use one set of root certificates to validate all mesh traffic, both inbound and outbound. Now an upstream proxy may have a leaf certificate signed by a CA that's different from the dialing proxy's. This PR makes changes to proxycfg and xds so that the upstream TLS validation uses different root certificates depending on which cluster is being dialed.	3 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	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
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

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
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
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
freddygv	60066e5154	Exclude default partition from GatewayKey string ... This will behave the way we handle SNI and SPIFFE IDs, where the default partition is excluded. Excluding the default ensures that don't attempt to compare default.dc2 to dc2 in OSS.	3 years ago

freddygv	7e65678c52	Update mesh gateway proxy watches for partitions ... This commit updates mesh gateway watches for cross-partitions communication. * Mesh gateways are keyed by partition and datacenter. * Mesh gateways will now watch gateways in partitions that export services to their partition. * Mesh gateways in non-default partitions will not have cross-datacenter watches. They are not involved in traditional WAN federation.	3 years ago

freddygv	af52d21884	Update prepared query cluster SAN validation ... Previously SAN validation for prepared queries was broken because we validated against the name, namespace, and datacenter for prepared queries. However, prepared queries can target: - Services with a name that isn't their own - Services in multiple datacenters This means that the SpiffeID to validate needs to be based on the prepared query endpoints, and not the prepared query's upstream definition. This commit updates prepared query clusters to account for that.	3 years ago
freddygv	85878685b7	Fixup proxy config test fixtures ... - The TestNodeService helper created services with the fixed name "web", and now that name is overridable. - The discovery chain snapshot didn't have prepared query endpoints so the endpoints tests were missing data for prepared queries	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

Matt Keeler	be01c4241d	Default Cache rate limiting options in New ... Also get rid of the TestCache helper which was where these defaults were happening previously.	4 years ago
Matt Keeler	12acdd7481	Disable background cache refresh for Connect Leaf Certs ... The rationale behind removing them is that all of our own code (xDS, builtin connect proxy) use the cache notification mechanism. This ensures that the blocking fetch behind the scenes is always executing. Therefore the only way you might go to get a certificate and have to wait is when 1) the request has never been made for that cert before or 2) you are using the v1/agent/connect/ca/leaf API for retrieving the cert yourself. In the first case, the refresh change doesn’t alter the behavior. In the second case, it can be mitigated by using blocking queries with that API which just like normal cache notification mechanism will cause the blocking fetch to be initiated and to get leaf certs as soon as needed. If you are not using blocking queries, or Envoy/xDS, or the builtin connect proxy but are retrieving the certs yourself then the HTTP endpoint might take a little longer to respond. This also renames the RefreshTimeout field on the register options to QueryTimeout to more accurately reflect that it is used for any type that supports blocking queries.	4 years ago

Freddy	9ed325ba8b	Enable gateways to resolve hostnames to IPv4 addresses (#7999) ... 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.	5 years ago

Kyle Havlovitz	247f9eaf13	Allow ingress gateways to route traffic based on Host header ... This commit adds the necessary changes to allow an ingress gateway to route traffic from a single defined port to multiple different upstream services in the Consul mesh. To do this, we now require all HTTP requests coming into the ingress gateway to specify a Host header that matches "<service-name>.*" in order to correctly route traffic to the correct service. - Differentiate multiple listener's route names by port - Adds a case in xds for allowing default discovery chains to create a route configuration when on an ingress gateway. This allows default services to easily use host header routing - ingress-gateways have a single route config for each listener that utilizes domain matching to route to different services.	5 years ago
