R.B. Boyer	85a08bf8ed	server: strip local ACL tokens from RPCs during forwarding if crossing datacenters (#7419) ... Fixes #7414	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

Hans Hasselberg	804eb17094	connect: check if intermediate cert needs to be renewed. (#6835) ... Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates. This PR adds a check that renews the cert if it is half way through its validity period. In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.	5 years ago

For write operations they can call allAllowed to ensure that write access is granted to everything. * Make v1/agent/connect/authorize namespace aware * Update intention ACL enforcement This also changes how intention:read is granted. Before the Intention.List RPC would allow viewing an intention if the token had intention:read on the destination. However Intention.Match allowed viewing if access was allowed for either the source or dest side. Now Intention.List and Intention.Get fall in line with Intention.Matches previous behavior. Due to this being done a few different places ACL enforcement for a singular intention is now done with the CanRead and CanWrite methods on the intention itself. * Refactor Intention.Apply to make things easier to follow.	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

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

R.B. Boyer	c4b92d5534	connect: connect CA Roots in secondary datacenters should use a SigningKeyID derived from their local intermediate (#6513) ... This fixes an issue where leaf certificates issued in secondary datacenters would be reissued very frequently (every ~20 seconds) because the logic meant to detect root rotation was errantly triggering because a hash of the ultimate root (in the primary) was being compared against a hash of the local intermediate root (in the secondary) and always failing.	5 years ago
Matt Keeler	76cf54068b	Expand the QueryOptions and QueryMeta interfaces (#6545) ... In a previous PR I made it so that we had interfaces that would work enough to allow blockingQueries to work.

Notes: • If Go ever gets contracts/generics then we could get rid of all the Getters/Setters • protoc / protoc-gen-gogo are going to generate all the getters for us. • I copied all the getters/setters from the protobuf funcs into agent/structs/protobuf_compat.go • Also added JSON marshaling funcs that use jsonpb for protobuf types.	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

Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date. If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild> Providing the PROTOFILES var will override the default behavior of finding all the .proto files. * Start adding types to the agent/proto package These will be needed for some other work and are by no means comprehensive. * Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store. * Use protobuf marshalling of raft requests instead of msgpack for protoc generated types. This does not change any encoding of existing types. * Removed structs package automatically encoding with protobuf marshalling Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf` * Run update-vendor to fixup modules.txt Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical. * Rename some things and implement the structs.RPCInfo interface bits agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth. * Use the right encoding function. * Renamed agent/proto package to agent/agentpb to prevent package name conflicts * Update modules.txt to fix ordering * Change blockingQuery to take in interfaces for the query options and meta * Add %T to error output. * Add/Update some comments	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	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	9138a97054	Fix bug in service-resolver redirects if the destination uses a default resolver. (#6122) ... Also: - add back an internal http endpoint to dump a compiled discovery chain for debugging purposes Before the CompiledDiscoveryChain.IsDefault() method would test: - is this chain just one resolver step? - is that resolver step just the default? But what I forgot to test: - is that resolver step for the same service that the chain represents? This last point is important because if you configured just one config entry: kind = "service-resolver" name = "web" redirect { service = "other" } and requested the chain for "web" you'd get back a **default** resolver for "other". In the xDS code the IsDefault() method is used to determine if this chain is "empty". If it is then we use the pre-discovery-chain logic that just uses data embedded in the Upstream object (and still lets the escape hatches function). In the example above that means certain parts of the xDS code were going to try referencing a cluster named "web..." despite the other parts of the xDS code maintaining clusters named "other...".	5 years ago
R.B. Boyer	67a36e3452	handle structs.ConfigEntry decoding similarly to api.ConfigEntry decoding (#6106) ... Both 'consul config write' and server bootstrap config entries take a decoding detour through mapstructure on the way from HCL to an actual struct. They both may take in snake_case or CamelCase (for consistency) so need very similar handling. Unfortunately since they are operating on mirror universes of structs (api.* vs structs.*) the code cannot be identitical, so try to share the kind-configuration and duplicate the rest for now.	5 years ago

R.B. Boyer	40336fd353	agent: fix several data races and bugs related to node-local alias checks (#5876) ... The observed bug was that a full restart of a consul datacenter (servers and clients) in conjunction with a restart of a connect-flavored application with bring-your-own-service-registration logic would very frequently cause the envoy sidecar service check to never reflect the aliased service. Over the course of investigation several bugs and unfortunate interactions were corrected: (1) local.CheckState objects were only shallow copied, but the key piece of data that gets read and updated is one of the things not copied (the underlying Check with a Status field). When the stock code was run with the race detector enabled this highly-relevant-to-the-test-scenario field was found to be racy. Changes: a) update the existing Clone method to include the Check field b) copy-on-write when those fields need to change rather than incrementally updating them in place. This made the observed behavior occur slightly less often. (2) If anything about how the runLocal method for node-local alias check logic was ever flawed, there was no fallback option. Those checks are purely edge-triggered and failure to properly notice a single edge transition would leave the alias check incorrect until the next flap of the aliased check. The change was to introduce a fallback timer to act as a control loop to double check the alias check matches the aliased check every minute (borrowing the duration from the non-local alias check logic body). This made the observed behavior eventually go away when it did occur. (3) Originally I thought there were two main actions involved in the data race: A. The act of adding the original check (from disk recovery) and its first health evaluation. B. The act of the HTTP API requests coming in and resetting the local state when re-registering the same services and checks. It took awhile for me to realize that there's a third action at work: C. The goroutines associated with the original check and the later checks. The actual sequence of actions that was causing the bad behavior was that the API actions result in the original check to be removed and re-added _without waiting for the original goroutine to terminate_. This means for brief windows of time during check definition edits there are two goroutines that can be sending updates for the alias check status. In extremely unlikely scenarios the original goroutine sees the aliased check start up in `critical` before being removed but does not get the notification about the nearly immediate update of that check to `passing`. This is interlaced wit the new goroutine coming up, initializing its base case to `passing` from the current state and then listening for new notifications of edge triggers. If the original goroutine "finishes" its update, it then commits one more write into the local state of `critical` and exits leaving the alias check no longer reflecting the underlying check. The correction here is to enforce that the old goroutines must terminate before spawning the new one for alias checks.	6 years ago
