Daniel Nephin 09ae0ab94a 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.

Add DNS recursor strategy option (#10611)
This change adds a new `dns_config.recursor_strategy` option which
controls how Consul queries DNS resolvers listed in the `recursors`
config option. The supported options are `sequential` (default), and
`random`.

Closes #8807

Matt Keeler 7e4ea16149 Move some things around to allow for license updating via config reload
The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.

freddygv eeccba945d Replace TransparentProxy bool with ProxyMode
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:

- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.

This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

agent: introduce path allow list for requests going through the metrics proxy (#9059)
Added a new option `ui_config.metrics_proxy.path_allowlist`. This defaults to `["/api/v1/query", "/api/v1/query_range"]` when the metrics provider is set to `prometheus`.

Requests that do not use one of the allow-listed paths (via exact match) get a 403 Forbidden response instead.

Add per-agent reconnect timeouts (#8781)
This allows for client agent to be run in a more stateless manner where they may be abruptly terminated and not expected to come back. If advertising a per-agent reconnect timeout using the advertise_reconnect_timeout configuration when that agent leaves, other agents will wait only that amount of time for the agent to come back before reaping it.

This has the advantageous side effect of causing servers to deregister the node/services/checks for that agent sooner than if the global reconnect_timeout was used.

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
  }
}

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.

Daniel Nephin 2c2da41b3d 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.

Merge pull request #7964 from hashicorp/dnephin/remove-patch-slice-of-maps-forward-compat
config: Use HookWeakDecodeFromSlice in place of PatchSliceOfMaps
2020-06-08 19:53:04 -04:00
Daniel Nephin 7b99d9a25d 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.

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.
