Matt Keeler	77f44fa878	Various bits of cleanup detected when using Go Workspaces (#17462) ... TLDR with many modules the versions included in each diverged quite a bit. Attempting to use Go Workspaces produces a bunch of errors. This commit: 1. Fixes envoy-library-references.sh to work again 2. Ensures we are pulling in go-control-plane@v0.11.0 everywhere (previously it was at that version in some modules and others were much older) 3. Remove one usage of golang/protobuf that caused us to have a direct dependency on it. 4. Remove deprecated usage of the Endpoint field in the grpc resolver.Target struct. The current version of grpc (v1.55.0) has removed that field and recommended replacement with URL.Opaque and calls to the Endpoint() func when needing to consume the previous field. 4. `go work init <all the paths to go.mod files>` && `go work sync`. This syncrhonized versions of dependencies from the main workspace/root module to all submodules 5. Updated .gitignore to ignore the go.work and go.work.sum files. This seems to be standard practice at the moment. 6. Update doc comments in protoc-gen-consul-rate-limit to be go fmt compatible 7. Upgraded makefile infra to perform linting, testing and go mod tidy on all modules in a flexible manner. 8. Updated linter rules to prevent usage of golang/protobuf 9. Updated a leader peering test to account for an extra colon in a grpc error message.	1 year ago
R.B. Boyer	cd80ea18ff	grpc: ensure grpc resolver correctly uses lan/wan addresses on servers (#17270) ... The grpc resolver implementation is fed from changes to the router.Router. Within the router there is a map of various areas storing the addressing information for servers in those areas. All map entries are of the WAN variety except a single special entry for the LAN. Addressing information in the LAN "area" are local addresses intended for use when making a client-to-server or server-to-server request. The client agent correctly updates this LAN area when receiving lan serf events, so by extension the grpc resolver works fine in that scenario. The server agent only initially populates a single entry in the LAN area (for itself) on startup, and then never mutates that area map again. For normal RPCs a different structure is used for LAN routing. Additionally when selecting a server to contact in the local datacenter it will randomly select addresses from either the LAN or WAN addressed entries in the map. Unfortunately this means that the grpc resolver stack as it exists on server agents is either broken or only accidentally functions by having servers dial each other over the WAN-accessible address. If the operator disables the serf wan port completely likely this incidental functioning would break. This PR enforces that local requests for servers (both for stale reads or leader forwarded requests) exclusively use the LAN "area" information and also fixes it so that servers keep that area up to date in the router. A test for the grpc resolver logic was added, as well as a higher level full-stack test to ensure the externally perceived bug does not return.	2 years ago
