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
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

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

Freddy	19f6e1ca31	Log the correlation ID when blocking queries fire (#10689 ) Knowing that blocking queries are firing does not provide much information on its own.

Freddy	ed1082510d	Fixup discovery chain handling in transparent mode (#10168 ) Co-authored-by: R.B. Boyer <4903+rboyer@users.noreply.github.com> Previously we would associate the address of a discovery chain target with the discovery chain's filter chain. This was broken for a few reasons: - If the upstream is a virtual service, the client proxy has no way of dialing it because virtual services are not targets of their discovery chains. The targets are distinct services. This is addressed by watching the endpoints of all upstream services, not just their discovery chain targets. - If multiple discovery chains resolve to the same target, that would lead to multiple filter chains attempting to match on the target's virtual IP. This is addressed by only matching on the upstream's virtual IP. NOTE: this implementation requires an intention to the redirecting virtual service and not just to the final destination. This is how we can know that the virtual service is an upstream to watch. A later PR will look into traversing discovery chains when computing upstreams so that intentions are only required to the discovery chain targets.	4 years ago
Daniel Nephin	62efaaab21	config-entry: remove Kind and Name field from Mesh config entry No config entry needs a Kind field. It is only used to determine the Go type to target. As we introduce new config entries (like this one) we can remove the kind field and have the GetKind method return the single supported value. In this case (similar to proxy-defaults) the Name field is also unnecessary. We always use the same value. So we can omit the name field entirely.	4 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
Freddy	078c40425f	Rename "cluster" config entry to "mesh" (#10127 ) This config entry is being renamed primarily because in k8s the name cluster could be confusing given that the config entry applies across federated datacenters.

Daniel Nephin	2a26085b2c	connect: do not set QuerySource.Node Setting this field to a value is equivalent to using the 'near' query paramter. The intent is to sort the results by proximity to the node requesting them. However with connect we send the results to envoy, which doesn't care about the order, so setting this field is increasing the work performed for no gain. It is necessary to unset this field now because we would like connect to use streaming, but streaming does not support sorting by proximity.	4 years ago

Proxy listeners need to be dialed directly. - "transparent": Transparent mode enables configuring Envoy as a transparent proxy. Traffic must be captured and redirected to the inbound and outbound listeners. This PR also adds a struct for transparent proxy specific configuration. Initially this is not stored as a pointer.
