add primary keys to list keyring (#8522)
During gossip encryption key rotation it would be nice to be able to see if all nodes are using the same key. This PR adds another field to the json response from `GET v1/operator/keyring` which lists the primary keys in use per dc. That way an operator can tell when a key was successfully setup as primary key.

Based on https://github.com/hashicorp/serf/pull/611 to add primary key to list keyring output:

```json
[
  {
    "WAN": true,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 6,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "NumNodes": 6
  },
  {
    "WAN": false,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 8,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  },
  {
    "WAN": false,
    "Datacenter": "dc1",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 3,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  }
]
```

I intentionally did not change the CLI output because I didn't find a good way of displaying this information. There are a couple of options that we could implement later:
* add a flag to show the primary keys
* add a flag to show json output

Fixes #3393.

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.

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.

Updates to allow for Namespacing ACL resources in Consul Enterp… (#6675)
Main Changes:

• method signature updates everywhere to account for passing around enterprise meta.
• populate the EnterpriseAuthorizerContext for all ACL related authorizations.
• ACL resource listings now operate like the catalog or kv listings in that the returned entries are filtered down to what the token is allowed to see. With Namespaces its no longer all or nothing.
• Modified the acl.Policy parsing to abstract away basic decoding so that enterprise can do it slightly differently. Also updated method signatures so that when parsing a policy it can take extra ent metadata to use during rules validation and policy creation.

Secondary Changes:

• Moved protobuf encoding functions out of the agentpb package to eliminate circular dependencies.
• Added custom JSON unmarshalers for a few ACL resource types (to support snake case and to get rid of mapstructure)
• AuthMethod validator cache is now an interface as these will be cached per-namespace for Consul Enterprise.
• Added checks for policy/role link existence at the RPC API so we don’t push the request through raft to have it fail internally.
• Forward ACL token delete request to the primary datacenter when the secondary DC doesn’t have the token.
• Added a bunch of ACL test helpers for inserting ACL resource test data.

Notes:
   • If Go ever gets contracts/generics then we could get rid of all the Getters/Setters
   • protoc / protoc-gen-gogo are going to generate all the getters for us.
   • I copied all the getters/setters from the protobuf funcs into agent/structs/protobuf_compat.go
   • Also added JSON marshaling funcs that use jsonpb for protobuf types.

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.

Add support for implementing new requests with protobufs instea… (#6502)
* Add build system support for protobuf generation

This is done generically so that we don’t have to keep updating the makefile to add another proto generation.

Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date.

If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild>

Providing the PROTOFILES var will override the default behavior of finding all the .proto files.

* Start adding types to the agent/proto package

These will be needed for some other work and are by no means comprehensive.

* Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store.

* Use protobuf marshalling of raft requests instead of msgpack for protoc generated types.

This does not change any encoding of existing types.

* Removed structs package automatically encoding with protobuf marshalling

Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf`

* Run update-vendor to fixup modules.txt

Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical.

* Rename some things and implement the structs.RPCInfo interface bits

agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth.

* Use the right encoding function.

* Renamed agent/proto package to agent/agentpb to prevent package name conflicts

* Update modules.txt to fix ordering

* Change blockingQuery to take in interfaces for the query options and meta

* Add %T to error output.

agent: fix several data races and bugs related to node-local alias checks (#5876)
The observed bug was that a full restart of a consul datacenter (servers
and clients) in conjunction with a restart of a connect-flavored
application with bring-your-own-service-registration logic would very
frequently cause the envoy sidecar service check to never reflect the
aliased service.

Over the course of investigation several bugs and unfortunate
interactions were corrected:

(1)

local.CheckState objects were only shallow copied, but the key piece of
data that gets read and updated is one of the things not copied (the
underlying Check with a Status field). When the stock code was run with
the race detector enabled this highly-relevant-to-the-test-scenario field
was found to be racy.

Changes:

 a) update the existing Clone method to include the Check field
 b) copy-on-write when those fields need to change rather than
    incrementally updating them in place.

This made the observed behavior occur slightly less often.

(2)

If anything about how the runLocal method for node-local alias check
logic was ever flawed, there was no fallback option. Those checks are
purely edge-triggered and failure to properly notice a single edge
transition would leave the alias check incorrect until the next flap of
the aliased check.

The change was to introduce a fallback timer to act as a control loop to
double check the alias check matches the aliased check every minute
(borrowing the duration from the non-local alias check logic body).

This made the observed behavior eventually go away when it did occur.

(3)

Originally I thought there were two main actions involved in the data race:

A. The act of adding the original check (from disk recovery) and its
   first health evaluation.

B. The act of the HTTP API requests coming in and resetting the local
   state when re-registering the same services and checks.

It took awhile for me to realize that there's a third action at work:

C. The goroutines associated with the original check and the later
   checks.

The actual sequence of actions that was causing the bad behavior was
that the API actions result in the original check to be removed and
re-added _without waiting for the original goroutine to terminate_. This
means for brief windows of time during check definition edits there are
two goroutines that can be sending updates for the alias check status.

In extremely unlikely scenarios the original goroutine sees the aliased
check start up in `critical` before being removed but does not get the
notification about the nearly immediate update of that check to
`passing`.

This is interlaced wit the new goroutine coming up, initializing its
base case to `passing` from the current state and then listening for new
notifications of edge triggers.

If the original goroutine "finishes" its update, it then commits one
more write into the local state of `critical` and exits leaving the
alias check no longer reflecting the underlying check.

The correction here is to enforce that the old goroutines must terminate

R.B. Boyer 9542fdc9bc acl: adding Roles to Tokens (#5514)
Roles are named and can express the same bundle of permissions that can
currently be assigned to a Token (lists of Policies and Service
Identities). The difference with a Role is that it not itself a bearer
token, but just another entity that can be tied to a Token.

This lets an operator potentially curate a set of smaller reusable
Policies and compose them together into reusable Roles, rather than
always exploding that same list of Policies on any Token that needs
similar permissions.

This also refactors the acl replication code to be semi-generic to avoid
3x copypasta.

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.

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.

Rebecca Zanzig 0ec6d880f5 Support multiple tags for health and catalog http api endpoints (#4717)
* Support multiple tags for health and catalog api endpoints

Fixes #1781.

Adds a `ServiceTags` field to the ServiceSpecificRequest to support
multiple tags, updates the filter logic in the catalog store, and
propagates these change through to the health and catalog endpoints.

Note: Leaves `ServiceTag` in the struct, since it is being used as
part of the DNS lookup, which in turn uses the health check.

* Update the api package to support multiple tags

Includes additional tests.

* Update new tests to use the `require` library

* Update HealthConnect check after a bad merge

Pierre Souchay b0fc91a1d2 [Performance On Large clusters] Reduce updates on large services (#4720)
* [Performance On Large clusters] Checks do update services/nodes only when really modified to avoid too many updates on very large clusters

In a large cluster, when having a few thousands of nodes, the anti-entropy
mechanism performs lots of changes (several per seconds) while
there is no real change. This patch wants to improve this in order
to increase Consul scalability when using many blocking requests on
health for instance.

* [Performance for large clusters] Only updates index of service if service is really modified

* [Performance for large clusters] Only updates index of nodes if node is really modified

* Added comments / ensure IsSame() has clear semantics

* Avoid having modified boolean, return nil directly if stutures are Same

* Fixed unstable unit tests TestLeader_ChangeServerID

* Rewrite TestNode_IsSame() for better readability as suggested by @banks

* Rename ServiceNode.IsSame() into IsSameService() + added unit tests

* Do not duplicate TestStructs_ServiceNode_Conversions() and increase test coverage of IsSameService

* Clearer documentation in IsSameService

* Take into account ServiceProxy into ServiceNode.IsSameService()

* Fixed IsSameService() with all new structures

Paul Banks 92fe8c8e89 Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

Pierre Souchay 473e589d86 Implementation of Weights Data structures (#4468)
* Implementation of Weights Data structures

Adding this datastructure will allow us to resolve the
issues #1088 and #4198

This new structure defaults to values:
```
   { Passing: 1, Warning: 0 }
```

Which means, use weight of 0 for a Service in Warning State
while use Weight 1 for a Healthy Service.
Thus it remains compatible with previous Consul versions.

* Implemented weights for DNS SRV Records

* DNS properly support agents with weight support while server does not (backwards compatibility)

* Use Warning value of Weights of 1 by default

When using DNS interface with only_passing = false, all nodes
with non-Critical healthcheck used to have a weight value of 1.
While having weight.Warning = 0 as default value, this is probably
a bad idea as it breaks ascending compatibility.

Thus, we put a default value of 1 to be consistent with existing behaviour.

* Added documentation for new weight field in service description

* Better documentation about weights as suggested by @banks

* Return weight = 1 for unknown Check states as suggested by @banks

* Fixed typo (of -> or) in error message as requested by @mkeeler

* Fixed unstable unit test TestRetryJoin

* Fixed unstable tests

* Fixed wrong Fatalf format in `testrpc/wait.go`

* Added notes regarding DNS SRV lookup limitations regarding number of instances

* Documentation fixes and clarification regarding SRV records with weights as requested by @banks

* Rephrase docs
