R.B. Boyer	1b413b0444	connect: support defining intentions using layer 7 criteria (#8839 ) Extend Consul’s intentions model to allow for request-based access control enforcement for HTTP-like protocols in addition to the existing connection-based enforcement for unspecified protocols (e.g. tcp).	4 years ago
Daniel Nephin	282fbdfa75	api: rename HTTPServer to HTTPHandlers Resolves a TODO about naming. This type is a set of handlers for an http.Server, it is not itself a Server. It provides http.Handler functions.	4 years ago
Daniel Nephin	cdd392d77f	agent/consul: pass dependencies directly from agent In an upcoming change we will need to pass a grpc.ClientConnPool from BaseDeps into Server. While looking at that change I noticed all of the existing consulOption fields are already on BaseDeps. Instead of duplicating the fields, we can create a struct used by agent/consul, and use that struct in BaseDeps. This allows us to pass along dependencies without translating them into different representations. I also looked at moving all of BaseDeps in agent/consul, however that created some circular imports. Resolving those cycles wouldn't be too bad (it was only an error in agent/consul being imported from cache-types), however this change seems a little better by starting to introduce some structure to BaseDeps. This change is also a small step in reducing the scope of Agent. Also remove some constants that were only used by tests, and move the relevant comment to where the live configuration is set. Removed some validation from NewServer and NewClient, as these are not really runtime errors. They would be code errors, which will cause a panic anyway, so no reason to handle them specially here.	4 years ago
Daniel Nephin	330be5b740	agent/token: Move token persistence out of agent And into token.Store. This change isolates any awareness of token persistence in a single place. It is a small step in allowing Agent.New to accept its dependencies.	4 years ago

Matt Keeler	3dbbd2d37d	Implement Client Agent Auto Config There are a couple of things in here. First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism. This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.	4 years ago
Matt Keeler	8837907de4	Make the Agent Cache more Context aware (#8092 ) Blocking queries issues will still be uncancellable (that cannot be helped until we get rid of net/rpc). However this makes it so that if calling getWithIndex (like during a cache Notify go routine) we can cancell the outer routine. Previously it would keep issuing more blocking queries until the result state actually changed.	5 years ago
Daniel Nephin	c662f0f0de	Fix a number of problems found by staticcheck Some of these problems are minor (unused vars), but others are real bugs (ignored errors). Co-authored-by: Matt Keeler <mkeeler@users.noreply.github.com>	5 years ago
Daniel Nephin	f46d1b5c94	agent/structs: Remove ServiceID.Init and CheckID.Init The Init method provided the same functionality as the New constructor. The constructor is both more widely used, and more idiomatic, so remove the Init method. This change is in preparation for fixing printing of these IDs.	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
Pierre Souchay	2300e2d4ba	agent: take Prometheus MIME-type header into account (#7371 ) This will avoid adding format=prometheus in request and to parse more easily metrics using Prometheus.

Matt Keeler	d8c0be2c84	agent: add ACL enforcement to the v1/agent/health/service/* endpoints This adds acl enforcement to the two endpoints that were missing it. Note that in the case of getting a services health by its id, we still must first lookup the service so we still "leak" information about a service with that ID existing. There isn't really a way around it though as ACLs are meant to check service names.	5 years ago

Matt Keeler	8bd34e126f	Intentions ACL enforcement updates (#7028 ) * Renamed structs.IntentionWildcard to structs.WildcardSpecifier * Refactor ACL Config Get rid of remnants of enterprise only renaming. Add a WildcardName field for specifying what string should be used to indicate a wildcard. * Add wildcard support in the ACL package For read operations they can call anyAllowed to determine if any read access to the given resource would be granted. 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	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.

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

When set at the agent level, it will limit the output for all checks monitored by the agent. When set at the check level, it can override the agent max for a specific check but only if it is lower than the agent max. Default value is 4k, and input must be at least 1.	5 years ago
Matt Keeler	f3d9b999ee	Add tagged addresses for services (#5965 ) This allows addresses to be tagged at the service level similar to what we allow for nodes already.

Matt Keeler	afa1cc98d1	Implement data filtering of some endpoints (#5579 ) Fixes: #4222 # Data Filtering This PR will implement filtering for the following endpoints: ## Supported HTTP Endpoints - `/agent/checks` - `/agent/services` - `/catalog/nodes` - `/catalog/service/:service` - `/catalog/connect/:service` - `/catalog/node/:node` - `/health/node/:node` - `/health/checks/:service` - `/health/service/:service` - `/health/connect/:service` - `/health/state/:state` - `/internal/ui/nodes` - `/internal/ui/services` More can be added going forward and any endpoint which is used to list some data is a good candidate. ## Usage When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of: ``` <selector> == <value> <selector> != <value> <value> in <selector> <value> not in <selector> <selector> contains <value> <selector> not contains <value> <selector> is empty <selector> is not empty not <other expression> <expression 1> and <expression 2> <expression 1> or <expression 2> ``` Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library ## Other changes Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.	6 years ago

Matt Keeler	118adbb123	ACL Token Persistence and Reloading (#5328 ) This PR adds two features which will be useful for operators when ACLs are in use. 1. Tokens set in configuration files are now reloadable. 2. If `acl.enable_token_persistence` is set to `true` in the configuration, tokens set via the `v1/agent/token` endpoint are now persisted to disk and loaded when the agent starts (or during configuration reload) Note that token persistence is opt-in so our users who do not want tokens on the local disk will see no change. Some other secondary changes: * Refactored a bunch of places where the replication token is retrieved from the token store. This token isn't just for replicating ACLs and now it is named accordingly. * Allowed better paths in the `v1/agent/token/` API. Instead of paths like: `v1/agent/token/acl_replication_token` the path can now be just `v1/agent/token/replication`. The old paths remain to be valid. * Added a couple new API functions to set tokens via the new paths. Deprecated the old ones and pointed to the new names. The names are also generally better and don't imply that what you are setting is for ACLs but rather are setting ACL tokens. There is a minor semantic difference there especially for the replication token as again, its no longer used only for ACL token/policy replication. The new functions will detect 404s and fallback to using the older token paths when talking to pre-1.4.3 agents. * Docs updated to reflect the API additions and to show using the new endpoints. * Updated the ACL CLI set-agent-tokens command to use the non-deprecated APIs.	6 years ago
Matt Keeler	baa8946ea6	cache: Pass through wait query param to the cache.Get (#5203 ) This adds a MaxQueryTime field to the connect ca leaf cache request type and populates it via the wait query param. The cache will then do the right thing and timeout the operation as expected if no new leaf cert is available within that time. Fixes #4462 The reproduction scenario in the original issue now times out appropriately.	6 years ago
Grégoire Seux	4f62a3b528	Implement /v1/agent/health/service/<service name> endpoint (#3551 ) This endpoint aggregates all checks related to <service id> on the agent and return an appropriate http code + the string describing the worst check. This allows to cleanly expose service status to other component, hiding complexity of multiple checks. This is especially useful to use consul to feed a load balancer which would delegate health checking to consul agent. Exposing this endpoint on the agent is necessary to avoid a hit on consul servers and avoid decreasing resiliency (this endpoint will work even if there is no consul leader in the cluster).	6 years ago

Given this is a potentially sensitive path, it is protected with an operator:read ACL and enable debug being set to true on the target agent. enable_debug still requires a restart. If ACLs are disabled, enable_debug is sufficient. * command/debug: use trace.out instead of .prof More in line with golang docs. * agent: fix comment wording * agent: wrap table driven tests in t.run()	6 years ago
