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

freddygv	5fbb26525b	Add awareness of server mode to TLS configurator ... Preivously the TLS configurator would default to presenting auto TLS certificates as client certificates. Server agents should not have this behavior and should instead present the manually configured certs. The autoTLS certs for servers are exclusively used for peering and should not be used as the default for outbound communication.	2 years ago
freddygv	650e1e32e0	Update TLS configurator for peering traffic ... When the TLS-enabled gRPC port receives a request for the expected it must use the auto-tls certificates.	2 years ago

R.B. Boyer	bb4d4040fb	server: ensure peer replication can successfully use TLS over external gRPC (#13733) ... Ensure that the peer stream replication rpc can successfully be used with TLS activated. Also: - If key material is configured for the gRPC port but HTTPS is not enabled now TLS will still be activated for the gRPC port. - peerstream replication stream opened by the establishing-side will now ignore grpc.WithBlock so that TLS errors will bubble up instead of being awkwardly delayed or suppressed	2 years ago

Dan Upton	b36d4e16b6	Support per-listener TLS configuration ⚙️ (#12504) ... Introduces the capability to configure TLS differently for Consul's listeners/ports (i.e. HTTPS, gRPC, and the internal multiplexed RPC port) which is useful in scenarios where you may want the HTTPS or gRPC interfaces to present a certificate signed by a well-known/public CA, rather than the certificate used for internal communication which must have a SAN in the form `server.<dc>.consul`.	3 years ago

Daniel Nephin	39f282c425	tlsutil: inline verifyIncomingHTTPS ... This function was only used in one place, and the indirection makes it slightly harder to see what the one caller is doing. Since it's only accesing a couple fields it seems like the logic can exist in the one caller.	3 years ago
Daniel Nephin	a25c817478	tlsutil: remove indirection and duplication ... VerifyIncomingRPC and verifyIncomingRPC were duplicate functions, and once one is removed, Config.verifyIncomingRPC is only called in one place. Remove 2 of the 3 functions to make the behaviour easier to follow (less indirection).	3 years ago
Daniel Nephin	13e5448c17	tlsutil: remove unnecessary getter functions ... These functions did nothing but hide the fields they were returning.	3 years ago
Daniel Nephin	66ba2e2463	tlsutil: unexport and remove indirection ... Unexport outgoingALPNRPCConfig since it is only used internally Remove the MutualTLSCapable->mutualTLSCapable indirection, we only need the exported method. Inline enableAgentTLSForChecks to make it more clear what it does, since it only has a single caller and is wrapping a single field lookup.	3 years ago
Daniel Nephin	486b97e2c9	tlsutil: fix default server name for health checks ... Don't use the agent node name or agent server name when EnableAgentTLSForChecks=false.	3 years ago
Daniel Nephin	2aad3f80fb	tlsutil: reduce interface provided to auto-config ... Replace two methods with a single one that returns the cert. This moves more of the logic into the single caller (auto-config). tlsutil.Configurator is widely used. By keeping it smaller and focused only on storing and returning TLS config, we make the code easier to follow. These two methods were more related to auto-config than to tlsutil, so reducing the interface moves the logic closer to the feature that requires it.	3 years ago

Daniel Nephin	a4432bb0b4	tlsutil: un-ptr and add godoc to autoTLs struct ... the autoTLS field on Configurator is only set once. By making it a value receiver it should be allocated as a single block of memory along with Configurator. Also add godoc to document what it is used for.	3 years ago
Daniel Nephin	08cd772626	tlsutil: remove unused method ... Method was only used in tests, and an equivalent function alraedy exists.	3 years ago
Daniel Nephin	8d9d6c6a09	tlsutil: unexport two types ... These types are only used internally and should not be exported. Also remove some unnecessary function wrapping.	3 years ago
Daniel Nephin	bca33d818f	tlsutil: remove the RLock from log ... The log method only needed the lock because it accessed version. By using an atomic instead of a lock, we can remove the risk that the comments call out, making log safer to use. Also updates the log name to match the function names, and adds some comments about how the lock is used.	3 years ago
Daniel Nephin	bcf23cd1b4	tlsutil: Un-method Configurator.check ... The method receiver was never used. Also rename it and add a godoc comment.	3 years ago
Daniel Nephin	b3fa778d91	tlsutil: fix a panic ... UpdateAutoTLSCA would panic if either of the calls errored, because the read lock was being unlocked incorrectly.	3 years ago
Daniel Nephin	6f51984313	tlsutil: un-embed the RWMutex ... Embedded structs make code harder to navidate because an IDE can not show all uses of the methods of that field separate from other uses. Generally embedding of structs should only be used to satisfy an interface, and in this case the Configurator type does not need to implement the RWMutex interface.	3 years ago
Christopher Broglie	f0307c73e5	Add support for configuring TLS ServerName for health checks ... Some TLS servers require SNI, but the Golang HTTP client doesn't include it in the ClientHello when connecting to an IP address. This change adds a new TLSServerName field to health check definitions to optionally set it. This fixes #9473.	4 years ago

Matt Keeler	dbb461a5d3	Allow setting verify_incoming* when using auto_encrypt or auto_config (#8394) ... Ensure that enabling AutoConfig sets the tls configurator properly This also refactors the TLS configurator a bit so the naming doesn’t imply only AutoEncrypt as the source of the automatically setup TLS cert info.	4 years ago
Matt Keeler	6e7acfa618	Add an AutoEncrypt “integration” test ... Also fix a bug where Consul could segfault if TLS was enabled but no client certificate was provided. How no one has reported this as a problem I am not sure.	4 years ago
Matt Keeler	9b01f9423c	Implement the insecure version of the Cluster.AutoConfig RPC endpoint ... Right now this is only hooked into the insecure RPC server and requires JWT authorization.

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
