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
Daniel Nephin	8ec029ae6a	Update comments that reference PatchSliceOfMaps ... To reference decode.HookWeakDecodeFromSlice instead. Also removes a step from the adding config fields checklist which is no longer necessary.	5 years ago
Daniel Nephin	c66c533d73	Merge pull request #7964 from hashicorp/dnephin/remove-patch-slice-of-maps-forward-compat ... config: Use HookWeakDecodeFromSlice in place of PatchSliceOfMaps	5 years ago
Daniel Nephin	75cbbe2702	config: add HookWeakDecodeFromSlice ... Currently opaque config blocks (config entries, and CA provider config) are modified by PatchSliceOfMaps, making it impossible for these opaque config sections to contain slices of maps. In order to fix this problem, any lazy-decoding of these blocks needs to support weak decoding of []map[string]interface{} to a struct type before PatchSliceOfMaps is replaces. This is necessary because these config blobs are persisted, and during an upgrade an older version of Consul could read one of the new configuration values, which would cause an error. To support the upgrade path, this commit first introduces the new hooks for weak decoding of []map[string]interface{} and uses them only in the lazy-decode paths. That way, in a future release, new style configuration will be supported by the older version of Consul. This decode hook has a number of advantages: 1. It no longer panics. It allows mapstructure to report the error 2. It no longer requires the user to declare which fields are slices of structs. It can deduce that information from the 'to' value. 3. It will make it possible to preserve opaque configuration, allowing for structured opaque config.	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	99eb583ebc	Replace goe/verify.Values with testify/require.Equal (#7993) ... * testing: replace most goe/verify.Values with require.Equal One difference between these two comparisons is that go/verify considers nil slices/maps to be equal to empty slices/maps, where as testify/require does not, and does not appear to provide any way to enable that behaviour. Because of this difference some expected values were changed from empty slices to nil slices, and some calls to verify.Values were left. * Remove github.com/pascaldekloe/goe/verify Reduce the number of assertion packages we use from 2 to 1	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	4a6569a4e3	tests: change default http_max_conns_per_client to 250 to ease tests (#7625) ... On recent Mac OS versions, the ulimit defaults to 256 by default, but many systems (eg: some Linux distributions) often limit this value to 1024. On validation of configuration, Consul now validates that the number of allowed files descriptors is bigger than http_max_conns_per_client. This make some unit tests failing on Mac OS. Use a less important value in unit test, so tests runs well by default on Mac OS without need for tuning the OS.	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

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	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
