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	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

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	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

Daniel Nephin	5fe7043439	agent/cache: Make all cache options RegisterOptions ... Previously the SupportsBlocking option was specified by a method on the type, and all the other options were specified from RegisterOptions. This change moves RegisterOptions to a method on the type, and moves SupportsBlocking into the options struct. Currently there are only 2 cache-types. So all cache-types can implement this method by embedding a struct with those predefined values. In the future if a cache type needs to be registered more than once with different options it can remove the embedded type and implement the method in a way that allows for paramaterization.	5 years ago

Andy Lindeman	c1cb18c648	proxycfg: support path exposed with non-HTTP2 protocol (#7510) ... If a proxied service is a gRPC or HTTP2 service, but a path is exposed using the HTTP1 or TCP protocol, Envoy should not be configured with `http2ProtocolOptions` for the cluster backing the path. A situation where this comes up is a gRPC service whose healthcheck or metrics route (e.g. for Prometheus) is an HTTP1 service running on a different port. Previously, if these were exposed either using `Expose: { Checks: true }` or `Expose: { Paths: ... }`, Envoy would still be configured to communicate with the path over HTTP2, which would not work properly.	5 years ago
R.B. Boyer	6adad71125	wan federation via mesh gateways (#6884) ... This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch: There are several distinct chunks of code that are affected: * new flags and config options for the server * retry join WAN is slightly different * retry join code is shared to discover primary mesh gateways from secondary datacenters * because retry join logic runs in the *agent* and the results of that operation for primary mesh gateways are needed in the *server* there are some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur at multiple layers of abstraction just to pass the data down to the right layer. * new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers * the function signature for RPC dialing picked up a new required field (the node name of the destination) * several new RPCs for manipulating a FederationState object: `FederationState:{Apply,Get,List,ListMeshGateways}` * 3 read-only internal APIs for debugging use to invoke those RPCs from curl * raft and fsm changes to persist these FederationStates * replication for FederationStates as they are canonically stored in the Primary and replicated to the Secondaries. * a special derivative of anti-entropy that runs in secondaries to snapshot their local mesh gateway `CheckServiceNodes` and sync them into their upstream FederationState in the primary (this works in conjunction with the replication to distribute addresses for all mesh gateways in all DCs to all other DCs) * a "gateway locator" convenience object to make use of this data to choose the addresses of gateways to use for any given RPC or gossip operation to a remote DC. This gets data from the "retry join" logic in the agent and also directly calls into the FSM. * RPC (`:8300`) on the server sniffs the first byte of a new connection to determine if it's actually doing native TLS. If so it checks the ALPN header for protocol determination (just like how the existing system uses the type-byte marker). * 2 new kinds of protocols are exclusively decoded via this native TLS mechanism: one for ferrying "packet" operations (udp-like) from the gossip layer and one for "stream" operations (tcp-like). The packet operations re-use sockets (using length-prefixing) to cut down on TLS re-negotiation overhead. * the server instances specially wrap the `memberlist.NetTransport` when running with gateway federation enabled (in a `wanfed.Transport`). The general gist is that if it tries to dial a node in the SAME datacenter (deduced by looking at the suffix of the node name) there is no change. If dialing a DIFFERENT datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh gateways to eventually end up in a server's :8300 port. * a new flag when launching a mesh gateway via `consul connect envoy` to indicate that the servers are to be exposed. This sets a special service meta when registering the gateway into the catalog. * `proxycfg/xds` notice this metadata blob to activate additional watches for the FederationState objects as well as the location of all of the consul servers in that datacenter. * `xds:` if the extra metadata is in place additional clusters are defined in a DC to bulk sink all traffic to another DC's gateways. For the current datacenter we listen on a wildcard name (`server.<dc>.consul`) that load balances all servers as well as one mini-cluster per node (`<node>.server.<dc>.consul`) * the `consul tls cert create` command got a new flag (`-node`) to help create an additional SAN in certs that can be used with this flavor of federation.	5 years ago
