R.B. Boyer	72f991d8d3	agent: remove agent cache dependency from service mesh leaf certificate management (#17075) ... * agent: remove agent cache dependency from service mesh leaf certificate management This extracts the leaf cert management from within the agent cache. This code was produced by the following process: 1. All tests in agent/cache, agent/cache-types, agent/auto-config, agent/consul/servercert were run at each stage. - The tests in agent matching .*Leaf were run at each stage. - The tests in agent/leafcert were run at each stage after they existed. 2. The former leaf cert Fetch implementation was extracted into a new package behind a "fake RPC" endpoint to make it look almost like all other cache type internals. 3. The old cache type was shimmed to use the fake RPC endpoint and generally cleaned up. 4. I selectively duplicated all of Get/Notify/NotifyCallback/Prepopulate from the agent/cache.Cache implementation over into the new package. This was renamed as leafcert.Manager. - Code that was irrelevant to the leaf cert type was deleted (inlining blocking=true, refresh=false) 5. Everything that used the leaf cert cache type (including proxycfg stuff) was shifted to use the leafcert.Manager instead. 6. agent/cache-types tests were moved and gently replumbed to execute as-is against a leafcert.Manager. 7. Inspired by some of the locking changes from derek's branch I split the fat lock into N+1 locks. 8. The waiter chan struct{} was eventually replaced with a singleflight.Group around cache updates, which was likely the biggest net structural change. 9. The awkward two layers or logic produced as a byproduct of marrying the agent cache management code with the leaf cert type code was slowly coalesced and flattened to remove confusion. 10. The .*Leaf tests from the agent package were copied and made to work directly against a leafcert.Manager to increase direct coverage. I have done a best effort attempt to port the previous leaf-cert cache type's tests over in spirit, as well as to take the e2e-ish tests in the agent package with Leaf in the test name and copy those into the agent/leafcert package to get more direct coverage, rather than coverage tangled up in the agent logic. There is no net-new test coverage, just coverage that was pushed around from elsewhere.	1 year ago

Freddy	7c3e9cd862	Hash namespace+proxy ID when creating socket path (#17204) ... UNIX domain socket paths are limited to 104-108 characters, depending on the OS. This limit was quite easy to exceed when testing the feature on Kubernetes, due to how proxy IDs encode the Pod ID eg: metrics-collector-59467bcb9b-fkkzl-hcp-metrics-collector-sidecar-proxy To ensure we stay under that character limit this commit makes a couple changes: - Use a b64 encoded SHA1 hash of the namespace + proxy ID to create a short and deterministic socket file name. - Add validation to proxy registrations and proxy-defaults to enforce a limit on the socket directory length.	2 years ago

Ashvitha	f95ffe0355	Allow HCP metrics collection for Envoy proxies ... Co-authored-by: Ashvitha Sridharan <ashvitha.sridharan@hashicorp.com> Co-authored-by: Freddy <freddygv@users.noreply.github.com> Add a new envoy flag: "envoy_hcp_metrics_bind_socket_dir", a directory where a unix socket will be created with the name `<namespace>_<proxy_id>.sock` to forward Envoy metrics. If set, this will configure: - In bootstrap configuration a local stats_sink and static cluster. These will forward metrics to a loopback listener sent over xDS. - A dynamic listener listening at the socket path that the previously defined static cluster is sending metrics to. - A dynamic cluster that will forward traffic received at this listener to the hcp-metrics-collector service. Reasons for having a static cluster pointing at a dynamic listener: - We want to secure the metrics stream using TLS, but the stats sink can only be defined in bootstrap config. With dynamic listeners/clusters we can use the proxy's leaf certificate issued by the Connect CA, which isn't available at bootstrap time. - We want to intelligently route to the HCP collector. Configuring its addreess at bootstrap time limits our flexibility routing-wise. More on this below. Reasons for defining the collector as an upstream in `proxycfg`: - The HCP collector will be deployed as a mesh service. - Certificate management is taken care of, as mentioned above. - Service discovery and routing logic is automatically taken care of, meaning that no code changes are required in the xds package. - Custom routing rules can be added for the collector using discovery chain config entries. Initially the collector is expected to be deployed to each admin partition, but in the future could be deployed centrally in the default partition. These config entries could even be managed by HCP itself.	2 years ago
Matt Keeler	085c0addc0	Protobuf Refactoring for Multi-Module Cleanliness (#16302) ... Protobuf Refactoring for Multi-Module Cleanliness This commit includes the following: Moves all packages that were within proto/ to proto/private Rewrites imports to account for the packages being moved Adds in buf.work.yaml to enable buf workspaces Names the proto-public buf module so that we can override the Go package imports within proto/buf.yaml Bumps the buf version dependency to 1.14.0 (I was trying out the version to see if it would get around an issue - it didn't but it also doesn't break things and it seemed best to keep up with the toolchain changes) Why: In the future we will need to consume other protobuf dependencies such as the Google HTTP annotations for openapi generation or grpc-gateway usage. There were some recent changes to have our own ratelimiting annotations. The two combined were not working when I was trying to use them together (attempting to rebase another branch) Buf workspaces should be the solution to the problem Buf workspaces means that each module will have generated Go code that embeds proto file names relative to the proto dir and not the top level repo root. This resulted in proto file name conflicts in the Go global protobuf type registry. The solution to that was to add in a private/ directory into the path within the proto/ directory. That then required rewriting all the imports. Is this safe? AFAICT yes The gRPC wire protocol doesn't seem to care about the proto file names (although the Go grpc code does tack on the proto file name as Metadata in the ServiceDesc) Other than imports, there were no changes to any generated code as a result of this.	2 years ago
Derek Menteer	2facf50923	Fix configuration merging for implicit tproxy upstreams. (#16000) ... Fix configuration merging for implicit tproxy upstreams. Change the merging logic so that the wildcard upstream has correct proxy-defaults and service-defaults values combined into it. It did not previously merge all fields, and the wildcard upstream did not exist unless service-defaults existed (it ignored proxy-defaults, essentially). Change the way we fetch upstream configuration in the xDS layer so that it falls back to the wildcard when no matching upstream is found. This is what allows implicit peer upstreams to have the correct "merged" config. Change proxycfg to always watch local mesh gateway endpoints whenever a peer upstream is found. This simplifies the logic so that we do not have to inspect the "merged" configuration on peer upstreams to extract the mesh gateway mode.	2 years ago
Derek Menteer	97ec5279aa	Fix local mesh gateway with peering discovery chains. (#15690) ... Fix local mesh gateway with peering discovery chains. Prior to this patch, discovery chains with peers would not properly honor the mesh gateway mode for two reasons. 1. An incorrect target upstream ID was used to lookup the mesh gateway mode. To fix this, the parent upstream uid is now used instead of the discovery-chain-target-uid to find the intended mesh gateway mode. 2. The watch for local mesh gateways was never initialized for discovery chains. To fix this, the discovery chains are now scanned, and a local GW watch is spawned if: the mesh gateway mode is local and the target is a peering connection.	2 years ago

Derek Menteer	418bd62c44	Fix mesh gateway configuration with proxy-defaults (#15186) ... * Fix mesh gateway proxy-defaults not affecting upstreams. * Clarify distinction with upstream settings Top-level mesh gateway mode in proxy-defaults and service-defaults gets merged into NodeService.Proxy.MeshGateway, and only gets merged with the mode attached to an an upstream in proxycfg/xds. * Fix mgw mode usage for peered upstreams There were a couple issues with how mgw mode was being handled for peered upstreams. For starters, mesh gateway mode from proxy-defaults and the top-level of service-defaults gets stored in NodeService.Proxy.MeshGateway, but the upstream watch for peered data was only considering the mesh gateway config attached in NodeService.Proxy.Upstreams[i]. This means that applying a mesh gateway mode via global proxy-defaults or service-defaults on the downstream would not have an effect. Separately, transparent proxy watches for peered upstreams didn't consider mesh gateway mode at all. This commit addresses the first issue by ensuring that we overlay the upstream config for peered upstreams as we do for non-peered. The second issue is addressed by re-using setupWatchesForPeeredUpstream when handling transparent proxy updates. Note that for transparent proxies we do not yet support mesh gateway mode per upstream, so the NodeService.Proxy.MeshGateway mode is used. * Fix upstream mesh gateway mode handling in xds This commit ensures that when determining the mesh gateway mode for peered upstreams we consider the NodeService.Proxy.MeshGateway config as a baseline. In absense of this change, setting a mesh gateway mode via proxy-defaults or the top-level of service-defaults will not have an effect for peered upstreams. * Merge service/proxy defaults in cfg resolver Previously the mesh gateway mode for connect proxies would be merged at three points: 1. On servers, in ComputeResolvedServiceConfig. 2. On clients, in MergeServiceConfig. 3. On clients, in proxycfg/xds. The first merge returns a ServiceConfigResponse where there is a top-level MeshGateway config from proxy/service-defaults, along with per-upstream config. The second merge combines per-upstream config specified at the service instance with per-upstream config specified centrally. The third merge combines the NodeService.Proxy.MeshGateway config containing proxy/service-defaults data with the per-upstream mode. This third merge is easy to miss, which led to peered upstreams not considering the mesh gateway mode from proxy-defaults. This commit removes the third merge, and ensures that all mesh gateway config is available at the upstream. This way proxycfg/xds do not need to do additional overlays. * Ensure that proxy-defaults is considered in wc Upstream defaults become a synthetic Upstream definition under a wildcard key "*". Now that proxycfg/xds expect Upstream definitions to have the final MeshGateway values, this commit ensures that values from proxy-defaults/service-defaults are the default for this synthetic upstream. * Add changelog.

Riddhi Shah	345191a0df	Service http checks data source for agentless proxies (#14924) ... Adds another datasource for proxycfg.HTTPChecks, for use on server agents. Typically these checks are performed by local client agents and there is no equivalent of this in agentless (where servers configure consul-dataplane proxies). Hence, the data source is mostly a no-op on servers but in the case where the service is present within the local state, it delegates to the cache data source.	2 years ago

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	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

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	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

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
