Chris S. Kim	29a297d3e9	Refactor client RPC timeouts (#14965 ) Fix an issue where rpc_hold_timeout was being used as the timeout for non-blocking queries. Users should be able to tune read timeouts without fiddling with rpc_hold_timeout. A new configuration `rpc_read_timeout` is created. Refactor some implementation from the original PR 11500 to remove the misleading linkage between RPCInfo's timeout (used to retry in case of certain modes of failures) and the client RPC timeouts.	2 years ago
Dan Upton	328e3ff563	proxycfg: rate-limit delivery of config snapshots (#14960 ) Adds a user-configurable rate limiter to proxycfg snapshot delivery, with a default limit of 250 updates per second. This addresses a problem observed in our load testing of Consul Dataplane where updating a "global" resource such as a wildcard intention or the proxy-defaults config entry could starve the Raft or Memberlist goroutines of CPU time, causing general cluster instability.	2 years ago

Mark Anderson	346b68a441	Fix up enterprise version tag. Changes to how the version string was handled created small regression with the release of consul 1.12.0 enterprise. Many tools use the Config:Version field reported by the agent/self resource to determine whether Consul is an enterprise or OSS instance, expect something like 1.12.0+ent for enterprise and simply 1.12.0 for OSS. This was accidentally broken during the runup to 1.12.x This work fixes the value returned by both the self endpoint in ["Config"]["Version"] and the metrics consul.version field.

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	d5498770fa	acl: make ACLDisabledTTL a constant This field was never user-configurable. We always overwrote the value with 120s from NonUserSource. However, we also never copied the value from RuntimeConfig to consul.Config, So the value in NonUserSource was always ignored, and we used the default value of 30s set by consul.DefaultConfig. All of this code is an unnecessary distraction because a user can not actually configure this value. This commit removes the fields and uses a constant value instad. Someone attempting to set acl.disabled_ttl in their config will now get an error about an unknown field, but previously the value was completely ignored, so the new behaviour seems more correct. We have to keep this field in the AutoConfig response for backwards compatibility, but the value will be ignored by the client, so it doesn't really matter what value we set.	3 years ago

Daniel Nephin	724a281e1c	config: Use config fields to warn about enterprise settings It is no safe to assumes that the mapstructure keys will contain all the keys because some config can be specified with command line flags or literals.

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
Daniel Nephin	77101eee82	config: rename Flags to BuilderOpts Flags is an overloaded term in this context. It generally is used to refer to command line flags. This struct, however, is a data object used as input to the construction. It happens to be partially populated by command line flags, but otherwise has very little to do with them. Renaming this struct should make the actual responsibility of this struct more obvious, and remove the possibility that it is confused with command line flags. This change is in preparation for adding additional fields to BuilderOpts.	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

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

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
