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

These values are defined in the local proxy on a per-service instance basis and should thus NOT be thought of as a global-level or even service-level value.	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

R.B. Boyer	8dcba472a2	xds: tcp services using the discovery chain should not assume RDS during LDS (#6623) ... Previously the logic for configuring RDS during LDS for L7 upstreams was overapplied to TCP proxies resulting in a cluster name of <emptystring> being used incorrectly. Fixes #6621	5 years ago
Matt Keeler	973341a592	ACL Authorizer overhaul (#6620) ... * ACL Authorizer overhaul To account for upcoming features every Authorization function can now take an extra *acl.EnterpriseAuthorizerContext. These are unused in OSS and will always be nil. Additionally the acl package has received some thorough refactoring to enable all of the extra Consul Enterprise specific authorizations including moving sentinel enforcement into the stubbed structs. The Authorizer funcs now return an acl.EnforcementDecision instead of a boolean. This improves the overall interface as it makes multiple Authorizers easily chainable as they now indicate whether they had an authoritative decision or should use some other defaults. A ChainedAuthorizer was added to handle this Authorizer enforcement chain and will never itself return a non-authoritative decision. * Include stub for extra enterprise rules in the global management policy * Allow for an upgrade of the global-management policy	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	ae79cdab1b	connect: introduce ExternalSNI field on service-defaults (#6324) ... Compiling this will set an optional SNI field on each DiscoveryTarget. When set this value should be used for TLS connections to the instances of the target. If not set the default should be used. Setting ExternalSNI will disable mesh gateway use for that target. It also disables several service-resolver features that do not make sense for an external service.	5 years ago
R.B. Boyer	72207256b9	xds: improve how envoy metrics are emitted (#6312) ... Since generated envoy clusters all are named using (mostly) SNI syntax we can have envoy read the various fields out of that structure and emit it as stats labels to the various telemetry backends. I changed the delimiter for the 'customization hash' from ':' to '~' because ':' is always reencoded by envoy as '_' when generating metrics keys.	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	c395affc93	connect: expose an API endpoint to compile the discovery chain (#6248) ... In addition to exposing compilation over the API cleaned up the structures that would be exchanged to be cleaner and easier to support and understand. Also removed ability to configure the envoy OverprovisioningFactor.	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.

R.B. Boyer	e039dfd7f8	connect: rework how the service resolver subset OnlyPassing flag works (#6173) ... The main change is that we no longer filter service instances by health, preferring instead to render all results down into EDS endpoints in envoy and merely label the endpoints as HEALTHY or UNHEALTHY. 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
