R.B. Boyer	e3cd4a8539	connect: use stronger validation that ingress gateways have compatible protocols defined for their upstreams (#8470) ... Fixes #8466 Since Consul 1.8.0 there was a bug in how ingress gateway protocol compatibility was enforced. At the point in time that an ingress-gateway config entry was modified the discovery chain for each upstream was checked to ensure the ingress gateway protocol matched. Unfortunately future modifications of other config entries were not validated against existing ingress-gateway definitions, such as: 1. create tcp ingress-gateway pointing to 'api' (ok) 2. create service-defaults for 'api' setting protocol=http (worked, but not ok) 3. create service-splitter or service-router for 'api' (worked, but caused an agent panic) If you were to do these in a different order, it would fail without a crash: 1. create service-defaults for 'api' setting protocol=http (ok) 2. create service-splitter or service-router for 'api' (ok) 3. create tcp ingress-gateway pointing to 'api' (fail with message about protocol mismatch) This PR introduces the missing validation. The two new behaviors are: 1. create tcp ingress-gateway pointing to 'api' (ok) 2. (NEW) create service-defaults for 'api' setting protocol=http ("ok" for back compat) 3. (NEW) create service-splitter or service-router for 'api' (fail with message about protocol mismatch) In consideration for any existing users that may be inadvertently be falling into item (2) above, that is now officiall a valid configuration to be in. For anyone falling into item (3) above while you cannot use the API to manufacture that scenario anymore, anyone that has old (now bad) data will still be able to have the agent use them just enough to generate a new agent/proxycfg error message rather than a panic. Unfortunately we just don't have enough information to properly fix the config entries.	4 years ago

Co-authored-by: Matt Keeler <mkeeler@users.noreply.github.com> Currently when passing hostname clusters to Envoy, we set each service instance registered with Consul as an LbEndpoint for the cluster. However, Envoy can only handle one per cluster: [2020-06-04 18:32:34.094][1][warning][config] [source/common/config/grpc_subscription_impl.cc:87] gRPC config for type.googleapis.com/envoy.api.v2.Cluster rejected: Error adding/updating cluster(s) dc2.internal.ddd90499-9b47-91c5-4616-c0cbf0fc358a.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint, server.dc2.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint Envoy is currently handling this gracefully by only picking one of the endpoints. However, we should avoid passing multiple to avoid these warning logs. This PR: * Ensures we only pass one endpoint, which is tied to one service instance. * We prefer sending an endpoint which is marked as Healthy by Consul. * If no endpoints are healthy we emit a warning and skip the cluster. * If multiple unique hostnames are spread across service instances we emit a warning and let the user know which will be resolved.	5 years ago

Daniel Nephin	c66c533d73	Merge pull request #7964 from hashicorp/dnephin/remove-patch-slice-of-maps-forward-compat ... config: Use HookWeakDecodeFromSlice in place of PatchSliceOfMaps	5 years ago
Daniel Nephin	75cbbe2702	config: add HookWeakDecodeFromSlice ... Currently opaque config blocks (config entries, and CA provider config) are modified by PatchSliceOfMaps, making it impossible for these opaque config sections to contain slices of maps. In order to fix this problem, any lazy-decoding of these blocks needs to support weak decoding of []map[string]interface{} to a struct type before PatchSliceOfMaps is replaces. This is necessary because these config blobs are persisted, and during an upgrade an older version of Consul could read one of the new configuration values, which would cause an error. To support the upgrade path, this commit first introduces the new hooks for weak decoding of []map[string]interface{} and uses them only in the lazy-decode paths. That way, in a future release, new style configuration will be supported by the older version of Consul. This decode hook has a number of advantages: 1. It no longer panics. It allows mapstructure to report the error 2. It no longer requires the user to declare which fields are slices of structs. It can deduce that information from the 'to' value. 3. It will make it possible to preserve opaque configuration, allowing for structured opaque config.	5 years ago
Chris Piraino	1a853fc954	Always require Host header values for http services (#7990) ... Previously, we did not require the 'service-name.*' host header value when on a single http service was exposed. However, this allows a user to get into a situation where, if they add another service to the listener, suddenly the previous service's traffic might not be routed correctly. Thus, we always require the Host header, even if there is only 1 service. Also, we add the make the default domain matching more restrictive by matching "service-name.ingress.*" by default. This lines up better with the namespace case and more accurately matches the Consul DNS value we expect people to use in this case.	5 years ago
Freddy	9ed325ba8b	Enable gateways to resolve hostnames to IPv4 addresses (#7999) ... The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option. If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS. Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.	5 years ago

Chris Piraino	f55e20a2f7	Allow ingress gateways to send empty clusters, routes, and listeners (#7795) ... This is useful when updating an config entry with no services, and the expected behavior is that envoy closes all listeners and clusters. We also allow empty routes because ingress gateways name route configurations based on the port of the listener, so it is important we remove any stale routes. Then, if a new listener with an old port is added, we will not have to deal with stale routes hanging around routing to the wrong place. Endpoints are associated with clusters, and thus by deleting the clusters we don't have to care about sending empty endpoint responses.	5 years ago

Kyle Havlovitz	247f9eaf13	Allow ingress gateways to route traffic based on Host header ... This commit adds the necessary changes to allow an ingress gateway to route traffic from a single defined port to multiple different upstream services in the Consul mesh. To do this, we now require all HTTP requests coming into the ingress gateway to specify a Host header that matches "<service-name>.*" in order to correctly route traffic to the correct service. - Differentiate multiple listener's route names by port - Adds a case in xds for allowing default discovery chains to create a route configuration when on an ingress gateway. This allows default services to easily use host header routing - ingress-gateways have a single route config for each listener that utilizes domain matching to route to different services.	5 years ago

Andy Lindeman	c1cb18c648	proxycfg: support path exposed with non-HTTP2 protocol (#7510) ... If a proxied service is a gRPC or HTTP2 service, but a path is exposed using the HTTP1 or TCP protocol, Envoy should not be configured with `http2ProtocolOptions` for the cluster backing the path. A situation where this comes up is a gRPC service whose healthcheck or metrics route (e.g. for Prometheus) is an HTTP1 service running on a different port. Previously, if these were exposed either using `Expose: { Checks: true }` or `Expose: { Paths: ... }`, Envoy would still be configured to communicate with the path over HTTP2, which would not work properly.	5 years ago

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
Matt Keeler	4c9577678e	xDS Mesh Gateway Resolver Subset Fixes (#7294) ... * xDS Mesh Gateway Resolver Subset Fixes The first fix was that clusters were being generated for every service resolver subset regardless of there being any service instances of the associated service in that dc. The previous logic didn’t care at all but now it will omit generating those clusters unless we also have service instances that should be proxied. The second fix was to respect the DefaultSubset of a service resolver so that mesh-gateways would configure the endpoints of the unnamed subset cluster to only those endpoints matched by the default subsets filters. * Refactor the gateway endpoint generation to be a little easier to read	5 years ago

Matt Keeler	e4ea9b0a96	Updates to allow for Namespacing ACL resources in Consul Enterp… (#6675) ... Main Changes: • method signature updates everywhere to account for passing around enterprise meta. • populate the EnterpriseAuthorizerContext for all ACL related authorizations. • ACL resource listings now operate like the catalog or kv listings in that the returned entries are filtered down to what the token is allowed to see. With Namespaces its no longer all or nothing. • Modified the acl.Policy parsing to abstract away basic decoding so that enterprise can do it slightly differently. Also updated method signatures so that when parsing a policy it can take extra ent metadata to use during rules validation and policy creation. Secondary Changes: • Moved protobuf encoding functions out of the agentpb package to eliminate circular dependencies. • Added custom JSON unmarshalers for a few ACL resource types (to support snake case and to get rid of mapstructure) • AuthMethod validator cache is now an interface as these will be cached per-namespace for Consul Enterprise. • Added checks for policy/role link existence at the RPC API so we don’t push the request through raft to have it fail internally. • Forward ACL token delete request to the primary datacenter when the secondary DC doesn’t have the token. • Added a bunch of ACL test helpers for inserting ACL resource test data.	5 years ago

Freddy	fdd10dd8b8	Expose HTTP-based paths through Connect proxy (#6446) ... Fixes: #5396 This PR adds a proxy configuration stanza called expose. These flags register listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only listening on the loopback interface, while still accepting traffic from non Connect-enabled services. Under expose there is a boolean checks flag that would automatically expose all registered HTTP and gRPC check paths. This stanza also accepts a paths list to expose individual paths. The primary use case for this functionality would be to expose paths for third parties like Prometheus or the kubelet. Listeners for requests to exposed paths are be configured dynamically at run time. Any time a proxy, or check can be registered, a listener can also be created. In this initial implementation requests to these paths are not authenticated/encrypted.	5 years ago

R.B. Boyer	8e22d80e35	connect: fix failover through a mesh gateway to a remote datacenter (#6259) ... Failover is pushed entirely down to the data plane by creating envoy clusters and putting each successive destination in a different load assignment priority band. For example this shows that normally requests go to 1.2.3.4:8080 but when that fails they go to 6.7.8.9:8080: - name: foo load_assignment: cluster_name: foo policy: overprovisioning_factor: 100000 endpoints: - priority: 0 lb_endpoints: - endpoint: address: socket_address: address: 1.2.3.4 port_value: 8080 - priority: 1 lb_endpoints: - endpoint: address: socket_address: address: 6.7.8.9 port_value: 8080 Mesh gateways route requests based solely on the SNI header tacked onto the TLS layer. Envoy currently only lets you configure the outbound SNI header at the cluster layer. If you try to failover through a mesh gateway you ideally would configure the SNI value per endpoint, but that's not possible in envoy today. This PR introduces a simpler way around the problem for now: 1. We identify any target of failover that will use mesh gateway mode local or remote and then further isolate any resolver node in the compiled discovery chain that has a failover destination set to one of those targets. 2. For each of these resolvers we will perform a small measurement of comparative healths of the endpoints that come back from the health API for the set of primary target and serial failover targets. We walk the list of targets in order and if any endpoint is healthy we return that target, otherwise we move on to the next target. 3. The CDS and EDS endpoints both perform the measurements in (2) for the affected resolver nodes. 4. For CDS this measurement selects which TLS SNI field to use for the cluster (note the cluster is always going to be named for the primary target) 5. For EDS this measurement selects which set of endpoints will populate the cluster. Priority tiered failover is ignored. One of the big downsides to this approach to failover is that the failover detection and correction is going to be controlled by consul rather than deferring that entirely to the data plane as with the prior version. This also means that we are bound to only failover using official health signals and cannot make use of data plane signals like outlier detection to affect failover. In this specific scenario the lack of data plane signals is ok because the effectiveness is already muted by the fact that the ultimate destination endpoints will have their data plane signals scrambled when they pass through the mesh gateway wrapper anyway so we're not losing much. Another related fix is that we now use the endpoint health from the underlying service, not the health of the gateway (regardless of failover mode).	5 years ago

R.B. Boyer	f02924fafe	connect: simplify the compiled discovery chain data structures (#6242) ... This should make them better for sending over RPC or the API. Instead of a chain implemented explicitly like a linked list (nodes holding pointers to other nodes) instead switch to a flat map of named nodes with nodes linking other other nodes by name. The shipped structure is just a map and a string to indicate which key to start from. Other changes: * inline the compiler option InferDefaults as true * introduce compiled target config to avoid needing to send back additional maps of Resolvers; future target-specific compiled state can go here * move compiled MeshGateway out of the Resolver and into the TargetConfig where it makes more sense.	5 years ago
R.B. Boyer	6393edba53	connect: reconcile how upstream configuration works with discovery chains (#6225) ... * connect: reconcile how upstream configuration works with discovery chains The following upstream config fields for connect sidecars sanely integrate into discovery chain resolution: - Destination Namespace/Datacenter: Compilation occurs locally but using different default values for namespaces and datacenters. The xDS clusters that are created are named as they normally would be. - Mesh Gateway Mode (single upstream): If set this value overrides any value computed for any resolver for the entire discovery chain. The xDS clusters that are created may be named differently (see below). - Mesh Gateway Mode (whole sidecar): If set this value overrides any value computed for any resolver for the entire discovery chain. If this is specifically overridden for a single upstream this value is ignored in that case. The xDS clusters that are created may be named differently (see below). - Protocol (in opaque config): If set this value overrides the value computed when evaluating the entire discovery chain. If the normal chain would be TCP or if this override is set to TCP then the result is that we explicitly disable L7 Routing and Splitting. The xDS clusters that are created may be named differently (see below). - Connect Timeout (in opaque config): If set this value overrides the value for any resolver in the entire discovery chain. The xDS clusters that are created may be named differently (see below). If any of the above overrides affect the actual result of compiling the discovery chain (i.e. "tcp" becomes "grpc" instead of being a no-op override to "tcp") then the relevant parameters are hashed and provided to the xDS layer as a prefix for use in naming the Clusters. This is to ensure that if one Upstream discovery chain has no overrides and tangentially needs a cluster named "api.default.XXX", and another Upstream does have overrides for "api.default.XXX" that they won't cross-pollinate against the operator's wishes.

When OnlyPassing is set to true we will force consul checks in a 'warning' state to render as UNHEALTHY in envoy. Fixes #6171	5 years ago

Matt Keeler	18b29c45c4	New ACLs (#4791) ... This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week. Description At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers. On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though. Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though. All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management. Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are: A server running the new system must still support other clients using the legacy system. A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system. The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode. So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.	6 years ago
