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
R.B. Boyer	9a485cdb49	proxycfg: ensure that an irrecoverable error in proxycfg closes the xds session and triggers a replacement proxycfg watcher (#16497) ... Receiving an "acl not found" error from an RPC in the agent cache and the streaming/event components will cause any request loops to cease under the assumption that they will never work again if the token was destroyed. This prevents log spam (#14144, #9738). Unfortunately due to things like: - authz requests going to stale servers that may not have witnessed the token creation yet - authz requests in a secondary datacenter happening before the tokens get replicated to that datacenter - authz requests from a primary TO a secondary datacenter happening before the tokens get replicated to that datacenter The caller will get an "acl not found" *before* the token exists, rather than just after. The machinery added above in the linked PRs will kick in and prevent the request loop from looping around again once the tokens actually exist. For `consul-dataplane` usages, where xDS is served by the Consul servers rather than the clients ultimately this is not a problem because in that scenario the `agent/proxycfg` machinery is on-demand and launched by a new xDS stream needing data for a specific service in the catalog. If the watching goroutines are terminated it ripples down and terminates the xDS stream, which CDP will eventually re-establish and restart everything. For Consul client usages, the `agent/proxycfg` machinery is ahead-of-time launched at service registration time (called "local" in some of the proxycfg machinery) so when the xDS stream comes in the data is already ready to go. If the watching goroutines terminate it should terminate the xDS stream, but there's no mechanism to re-spawn the watching goroutines. If the xDS stream reconnects it will see no `ConfigSnapshot` and will not get one again until the client agent is restarted, or the service is re-registered with something changed in it. This PR fixes a few things in the machinery: - there was an inadvertent deadlock in fetching snapshot from the proxycfg machinery by xDS, such that when the watching goroutine terminated the snapshots would never be fetched. This caused some of the xDS machinery to get indefinitely paused and not finish the teardown properly. - Every 30s we now attempt to re-insert all locally registered services into the proxycfg machinery. - When services are re-inserted into the proxycfg machinery we special case "dead" ones such that we unilaterally replace them rather that doing that conditionally.	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	30112288c8	Fix mesh gateways incorrectly matching peer locality. (#16257) ... Fix mesh gateways incorrectly matching peer locality. This fixes an issue where local mesh gateways use an incorrect address when attempting to forward traffic to a peered datacenter. Prior to this change it would use the lan address instead of the wan if the locality matched. This should never be done for peering, since we must route all traffic through the remote mesh gateway.	2 years ago
Derek Menteer	6599a9be1d	Fix nil-pointer panics from proxycfg package. (#16277) ... Prior to this PR, servers / agents would panic and crash if an ingress or api gateway were configured to use a discovery chain that both: 1. Referenced a peered service 2. Had a mesh gateway mode of local This could occur, because code for handling upstream watches was shared between both connect-proxy and the gateways. As a short-term fix, this PR ensures that the maps are always initialized for these gateway services. This PR also wraps the proxycfg execution and service registration calls with recover statements to ensure that future issues like this do not put the server into an unrecoverable state.	2 years ago

This removes endpoints support for builtin extensions since only the validate plugin was using it, and it is no longer used. It also removes test cases for endpoint validation.

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.
