Daniel Nephin	37eacf8192	auto-config: reduce awareness of config ... This is a small step to allowing Agent to accept its dependencies instead of creating them in New. There were two fields in autoconfig.Config that were used exclusively to load config. These were replaced with a single function, allowing us to move LoadConfig back to the config package. Also removed the WithX functions for building a Config. Since these were simple assignment, it appeared we were not getting much value from them.	4 years ago
Daniel Nephin	38980ebb4c	config: Make Source an interface ... This will allow us to accept config from auto-config without needing to go through a serialziation cycle.	4 years ago
Matt Keeler	67dec3b609	Require token replication to be enabled in secondary dcs when ACLs are enabled with AutoConfig (#8451) ... AutoConfig will generate local tokens for clients and the ability to use local tokens is gated off of token replication being enabled and being configured with a replication token. Therefore we already have a hard requirement on having token replication enabled, this commit just makes sure to surface that to the operator instead of having to discern what the issue is from RPC errors.	4 years ago

Matt Keeler	34034b76f5	Agent Auto Config: Implement Certificate Generation (#8360) ... Most of the groundwork was laid in previous PRs between adding the cert-monitor package to extracting the logic of signing certificates out of the connect_ca_endpoint.go code and into a method on the server. This also refactors the auto-config package a bit to split things out into multiple files.	4 years ago
Matt Keeler	be01c4241d	Default Cache rate limiting options in New ... Also get rid of the TestCache helper which was where these defaults were happening previously.	4 years ago
Pierre Souchay	505de6dc29	Added ratelimit to handle throtling cache (#8226) ... This implements a solution for #7863 It does: Add a new config cache.entry_fetch_rate to limit the number of calls/s for a given cache entry, default value = rate.Inf Add cache.entry_fetch_max_burst size of rate limit (default value = 2) The new configuration now supports the following syntax for instance to allow 1 query every 3s: command line HCL: -hcl 'cache = { entry_fetch_rate = 0.333}' in JSON { "cache": { "entry_fetch_rate": 0.333 } }	4 years ago
Matt Keeler	4a5b352c18	Require enabling TLS to enable Auto Config (#8159) ... On the servers they must have a certificate. On the clients they just have to set verify_outgoing to true to attempt TLS connections for RPCs. Eventually we may relax these restrictions but right now all of the settings we push down (acl tokens, acl related settings, certificates, gossip key) are sensitive and shouldn’t be transmitted over an unencrypted connection. Our guides and docs should recoommend verify_server_hostname on the clients as well. Another reason to do this is weird things happen when making an insecure RPC when TLS is not enabled. Basically it tries TLS anyways. We should probably fix that to make it clearer what is going on.	5 years ago
Matt Keeler	d6e05482ab	Allow cancelling startup when performing auto-config (#8157) ... Co-authored-by: Daniel Nephin <dnephin@hashicorp.com>	5 years ago
Matt Keeler	b0fcf86140	Change auto config authorizer to allow for future extension ... The envisioned changes would allow extra settings to enable dynamically defined auth methods to be used instead of or in addition to the statically defined one in the configuration.	5 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.	5 years ago
Daniel Nephin	692a4a8fc8	Merge pull request #7762 from hashicorp/dnephin/warn-on-unknown-service-file ... config: warn if a config file is being skipped because of its file extension	5 years ago
Daniel Nephin	be29d6bf75	config: warn when a config file is skipped ... All commands which read config (agent, services, and validate) will now print warnings when one of the config files is skipped because it did not match an expected format. Also ensures that config validate prints all warnings.	5 years ago

Daniel Nephin	476b57fe22	config: refactor to consolidate all File->Source loading ... Previously the logic for reading ConfigFiles and produces Sources was split between NewBuilder and Build. This commit moves all of the logic into NewBuilder so that Build() can operate entirely on Sources. This change is in preparation for logging warnings when files have an unsupported extension. It also reduces the scope of BuilderOpts, and gets us very close to removing Builder.options.	5 years ago
Daniel Nephin	219790ca49	config: Make ConfigFormat not a pointer ... The nil value was never used. We can avoid a bunch of complications by making the field a string value instead of a pointer. This change is in preparation for fixing a silent config failure.	5 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
Daniel Nephin	85e0338136	config: remove Args field from Flags ... This field was populated for one reason, to test that it was empty. Of all the callers, only a single one used this functionality. The rest constructed a `Flags{}` struct which did not set Args. I think this shows that the logic was in the wrong place. Only the agent command needs to care about validating the args. This commit removes the field, and moves the logic to the one caller that cares. Also fix some comments.	5 years ago
Hans Hasselberg	72f92ae7ca	agent: add option to disable agent cache for HTTP endpoints (#8023) ... This allows the operator to disable agent caching for the http endpoint. It is on by default for backwards compatibility and if disabled will ignore the url parameter `cached`.	5 years ago

Daniel Nephin	c88fae0aac	ci: Add staticcheck and fix most errors ... Three of the checks are temporarily disabled to limit the size of the diff, and allow us to enable all the other checks in CI. In a follow up we can fix the issues reported by the other checks one at a time, and enable them.	5 years ago
Pierre Souchay	e9d176db2a	Allow to restrict servers that can join a given Serf Consul cluster. (#7628) ... Based on work done in https://github.com/hashicorp/memberlist/pull/196 this allows to restrict the IP ranges that can join a given Serf cluster and be a member of the cluster. Restrictions on IPs can be done separatly using 2 new differents flags and config options to restrict IPs for LAN and WAN Serf.	5 years ago
Matt Keeler	cbe3a70f56	Update enterprise configurations to be in OSS ... This will emit warnings about the configs not doing anything but still allow them to be parsed. This also added the warnings for enterprise fields that we already had in OSS but didn’t change their enforcement behavior. For example, attempting to use a network segment will cause a hard error in OSS.	5 years ago

Pierre Souchay	be1c5c4b48	config: validate system limits against limits.http_max_conns_per_client (#7434) ... I spent some time today on my local Mac to figure out why Consul 1.6.3+ was not accepting limits.http_max_conns_per_client. This adds an explicit check on number of file descriptors to be sure it might work (this is no guarantee as if many clients are reaching the agent, it might consume even more file descriptors) Anyway, many users are fighting with RLIMIT_NOFILE, having a clear message would allow them to figure out what to fix. Example of message (reload or start): ``` 2020-03-11T16:38:37.062+0100 [ERROR] agent: Error starting agent: error="system allows a max of 512 file descriptors, but limits.http_max_conns_per_client: 8192 needs at least 8212" ```	5 years ago
Pierre Souchay	54b22c638d	config: allow running `consul agent -dev -ui-dir=some_path` (#7525) ... When run in with `-dev` in DevMode, it is not possible to replace the embeded UI with another one because `-dev` implies `-ui`. This commit allows this an slightly change the error message about Consul 0.7.0 which is very old and does not apply to current version anyway.	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	315d57bfb1	agent: sensible keyring error (#7272) ... Fixes #7231.

R.B. Boyer	0f44bcd3d8	agent: default the primary_datacenter to the datacenter if not configured (#7111) ... Something similar already happens inside of the server (agent/consul/server.go) but by doing it in the general config parsing for the agent we can have agent-level code rely on the PrimaryDatacenter field, too.	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

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
