Daniel Nephin c621b4a420 agent/consul: pass dependencies directly from agent
In an upcoming change we will need to pass a grpc.ClientConnPool from
BaseDeps into Server. While looking at that change I noticed all of the
existing consulOption fields are already on BaseDeps.

Instead of duplicating the fields, we can create a struct used by
agent/consul, and use that struct in BaseDeps. This allows us to pass
along dependencies without translating them into different
representations.

I also looked at moving all of BaseDeps in agent/consul, however that
created some circular imports. Resolving those cycles wouldn't be too
bad (it was only an error in agent/consul being imported from
cache-types), however this change seems a little better by starting to
introduce some structure to BaseDeps.

This change is also a small step in reducing the scope of Agent.

Also remove some constants that were only used by tests, and move the
relevant comment to where the live configuration is set.

Removed some validation from NewServer and NewClient, as these are not
really runtime errors. They would be code errors, which will cause a
panic anyway, so no reason to handle them specially here.

Pierre Souchay 617e0d2364 [BUGFIX] Avoid GetDatacenter* methods to flood Consul servers logs
When calling `GetDatacentersByDistance()` or `GetDatacentersMap()`, an
incorrect condition was used to diplay log message, thus flooding
Consul's logs.

Example of message:

```
  [WARN] agent.router: Non-server in server-only area: non_server=myClientNode area=lan
```

This message is only valid for WAN areas, filter to avoid creating
hundreds of logs/s on our clusters, each time someone is calling this
method.

Our logs were flooded by such messages when migrating our Consul servers
from 1.7.7 to 1.8.4.

This will issue fix #8663

Daniel Nephin 1e40f00567 agent/grpc: make TestHandler_EmitsStats predictable
Occasionally this test would flake. The flakes were fixed by:

1. Stopping the service and retrying to check on metrics. This way we
   also include the active_streams going to 0 in the metric calls.

2. Using a reference to the global Metrics. This way when other tests
   have background goroutines that are still shutting down, they won't
   emit metrics to the metric instance with the fake Sink. The stats
   test can patch the local reference to the global, so the existing
   statHandlers will continue to emit to the global, but the stats
   test will send all metrics to the replacement.

Daniel Nephin 4eb514a59f http: fix tests incorrectly using HTTPAddr to get the address of the
https server.

In #8234 I changed a few tests to use TestAgent.HTTPAddr() to find the
addr used in the test. Due to the way HTTPAddr() was implemented these
tests were passing, but I think the pass was incidental. HTTPAddr() was
not matching any servers, and was instead returning the last server,
which happened to be the one these tests wanted.

This commit fixes the implementation of HTTPAddr to panic if no match
was found. The tests which require an HTTPS server are changed to use
a new firstAddr() to look up the correct address.

secondaryIntermediateCertRenewalWatch abort on success (#8588)
secondaryIntermediateCertRenewalWatch was using `retryLoopBackoff` to

started `retryLoopBackoff` it would never leave that.
`retryLoopBackoffAbortOnSuccess` will return when renewing is
successful, like it was intended originally.

connect: fix bug in preventing some namespaced config entry modifications (#8601)
Whenever an upsert/deletion of a config entry happens, within the open
state store transaction we speculatively test compile all discovery
chains that may be affected by the pending modification to verify that
the write would not create an erroneous scenario (such as splitting
traffic to a subset that did not exist).

If a single discovery chain evaluation references two config entries
with the same kind and name in different namespaces then sometimes the
upsert/deletion would be falsely rejected. It does not appear as though
this bug would've let invalid writes through to the state store so the
correction does not require a cleanup phase.

Chris Piraino 80f923a47a Refactor state store usage to track unique service names
This commit refactors the state store usage code to track unique service
name changes on transaction commit. This means we only need to lookup
usage entries when reading the information, as opposed to iterating over
a large number of service indices.

- Take into account a service instance's name being changed
- Do not iterate through entire list of service instances, we only care
about whether there is 0, 1, or more than 1.

Using the newly provided state store methods, we periodically emit usage

We decided to emit these metrics from all servers, not just the leader,
because that means we do not have to care about leader election flapping
causing metrics turbulence, and it seems reasonable for each server to
emit its own view of the state, even if they should always converge
rapidly.

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.

Daniel Nephin 85655098be testing: Improve session_endpoint_test
While working on another change I caused a bunch of these tests to fail.
Unfortunately the failure messages were not super helpful at first.

One problem was that the request and response were created outside of
the retry. This meant that when the second attempt happened, the request
body was empty (because the buffer had been consumed), and so the
request was not actually being retried. This was fixed by moving more of
the request creation into the retry block.

Another problem was that these functions can return errors in two ways, and
are not consistent about which way they use. Some errors are returned to
the response writer, but the tests were not checking those errors, which
was causing a panic later on. This was fixed by adding a check for the
response code.

Also adds some missing t.Helper(), and has assertIndex use checkIndex so
that it is clear these are the same implementation.

This commit fixes a test that I saw flake locally while running tests. The test output from the monitor

To fix the problem a channel is closed when the goroutine starts. Shutdown is not called until this channel
is closed, which seems to greatly reduce the chance of a flake.

This required a second change (which I was planning on making anyway), which was to change the behaviour of
DataDir. Now in all cases the TestAgent will use the DataDir, and clean it up once the test is complete.

   a lot more context to someone trying to understand which functions
   call other functions.
2. these two functions call into a large number of functions already in

This is a small step to allowing Agent to accept its dependencies

to move LoadConfig back to the config package.

Also removed the WithX functions for building a Config. Since these were

connect: use stronger validation that ingress gateways have compatible protocols defined for their upstreams (#8470)
Fixes #8466

Since Consul 1.8.0 there was a bug in how ingress gateway protocol
compatibility was enforced. At the point in time that an ingress-gateway
config entry was modified the discovery chain for each upstream was
checked to ensure the ingress gateway protocol matched. Unfortunately
future modifications of other config entries were not validated against
existing ingress-gateway definitions, such as:

1. create tcp ingress-gateway pointing to 'api' (ok)
2. create service-defaults for 'api' setting protocol=http (worked, but not ok)
3. create service-splitter or service-router for 'api' (worked, but caused an agent panic)

If you were to do these in a different order, it would fail without a
crash:

1. create service-defaults for 'api' setting protocol=http (ok)
2. create service-splitter or service-router for 'api' (ok)
3. create tcp ingress-gateway pointing to 'api' (fail with message about
   protocol mismatch)

This PR introduces the missing validation. The two new behaviors are:

1. create tcp ingress-gateway pointing to 'api' (ok)
2. (NEW) create service-defaults for 'api' setting protocol=http ("ok" for back compat)
3. (NEW) create service-splitter or service-router for 'api' (fail with
   message about protocol mismatch)

In consideration for any existing users that may be inadvertently be
falling into item (2) above, that is now officiall a valid configuration
to be in. For anyone falling into item (3) above while you cannot use
the API to manufacture that scenario anymore, anyone that has old (now
bad) data will still be able to have the agent use them just enough to
generate a new agent/proxycfg error message rather than a panic.
Unfortunately we just don't have enough information to properly fix the
config entries.

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.

Fix some broken code in master
There were several PRs that while all passed CI independently, when they all got merged into the same branch caused compilation errors in test code.

The main changes that caused issues where changing agent/cache.Cache.New to require a concrete options struct instead of a pointer. This broke the cert monitor tests and the catalog_list_services_test.go. Another change was made to unembed the http.Server from the agent.HTTPServer struct. That coupled with another change to add a test to ensure cache rate limiting coming from HTTP requests was working as expected caused compilation failures.

Added ratelimit to handle throtling cache (#8226)

It does:

    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": {

Daniel Nephin 80ff174880 testutil: NewLogBuffer - buffer logs until a test fails
Replaces #7559

Running tests in parallel, with background goroutines, results in test output not being associated with the correct test. `go test` does not make any guarantees about output from goroutines being attributed to the correct test case.

Attaching log output from background goroutines also cause data races.  If the goroutine outlives the test, it will race with the test being marked done. Previously this was noticed as a panic when logging, but with the race detector enabled it is shown as a data race.

The previous solution did not address the problem of correct test attribution because test output could still be hidden when it was associated with a test that did not fail. You would have to look at all of the log output to find the relevant lines. It also made debugging test failures more difficult because each log line was very long.

This commit attempts a new approach. Instead of printing all the logs, only print when a test fails. This should work well when there are a small number of failures, but may not work well when there are many test failures at the same time. In those cases the failures are unlikely a result of a specific test, and the log output is likely less useful.

All of the logs are printed from the test goroutine, so they should be associated with the correct test.

Also removes some test helpers that were not used, or only had a single caller. Packages which expose many functions with similar names can be difficult to use correctly.

Disable background cache refresh for Connect Leaf Certs
The rationale behind removing them is that all of our own code (xDS, builtin connect proxy) use the cache notification mechanism. This ensures that the blocking fetch behind the scenes is always executing. Therefore the only way you might go to get a certificate and have to wait is when 1) the request has never been made for that cert before or 2) you are using the v1/agent/connect/ca/leaf API for retrieving the cert yourself.

In the first case, the refresh change doesn’t alter the behavior. In the second case, it can be mitigated by using blocking queries with that API which just like normal cache notification mechanism will cause the blocking fetch to be initiated and to get leaf certs as soon as needed.

If you are not using blocking queries, or Envoy/xDS, or the builtin connect proxy but are retrieving the certs yourself then the HTTP endpoint might take a little longer to respond.

This also renames the RefreshTimeout field on the register options to QueryTimeout to more accurately reflect that it is used for any type that supports blocking queries.

Fix issue with changing the agent token causing failure to renew the auto-encrypt certificate
The fallback method would still work but it would get into a state where it would let the certificate expire for 10s before getting a new one. And the new one used the less secure RPC endpoint.

This is also a pretty large refactoring of the auto encrypt code. I was going to write some tests around the certificate monitoring but it was going to be impossible to get a TestAgent configured in such a way that I could write a test that ran in less than an hour or two to exercise the functionality.

Moving the certificate monitoring into its own package will allow for dependency injection and in particular mocking the cache types to control how it hands back certificates and how long those certificates should live. This will allow for exercising the main loop more than would be possible with it coupled so tightly with the Agent.

Daniel Nephin f913bed325 checks: wait for goroutine to complete
CheckAlias already had a waitGroup, but the Add() call was happening too late, which was causing a race in tests. The add must happen before the goroutine is started.

CheckHTTP did not have a waitGroup, so I added it to match CheckAlias.

It looks like a lot of the implementation could be shared, and may not need all of channel, waitgroup and bool, but I will leave that refactor for another time.

Daniel Nephin 7599e280de stream: handle empty event in TestEventSnapshot
When the race detector is enabled we see this test fail occasionally. The reordering of execution seems to make it possible for the snapshot splice to happen before any events are published to the topicBuffers.

We can handle this case in the test the same way it is handled by a subscription, by proceeding to the next event.

Daniel Nephin 3fcb2e16f4 state: un-method funcs that don't use their receiver
This change was mostly automated with the following

First generate a list of functions with:

  git grep -o 'Store) \([^(]\+\)(tx \*txn' ./agent/consul/state | awk '{print $2}' | grep -o '^[^(]\+'

Then the list was curated a bit with trial/error to remove and add funcs
as necessary.

Finally the replacement was done with:

  dir=agent/consul/state
  file=${1-funcnames}

  while read fn; do
    echo "$fn"
    sed -i -e "s/(s \*Store) $fn(/$fn(/" $dir/*.go
    sed -i -e "s/s\.$fn(/$fn(/" $dir/*.go

Making these functions allows them to be used without introducing

from streaming Event processors, which do not have a store.

This change is being made ahead of the streaming work to get to reduce
the size of the streaming diff.

Daniel Nephin a2f8605c66 stream: Add forceClose and refactor subscription filtering
Move the subscription context to Next. context.Context should generally
never be stored in a struct because it makes that struct only valid
while the context is valid. This is rarely obvious from the caller.
Adds a forceClosed channel in place of the old context, and uses the new
context as a way for the caller to stop the Subscription blocking.

Remove some recursion out of bufferImte.Next. The caller is already looping so we can continue
in that loop instead of recursing. This ensures currentItem is updated immediately (which probably
does not matter in practice), and also removes the chance that we overflow the stack.

NextNoBlock and FollowAfter do not need to handle bufferItem.Err, the caller already
handles it.

Moves filter to a method to simplify Next, and more explicitly separate filtering from looping.

Also improve some godoc

Only unwrap itemBuffer.Err when necessary

Daniel Nephin aa571bd0ce state: Move change processing out of EventPublisher
EventPublisher was receiving TopicHandlers, which had a couple of
problems:

- ChangeProcessors were being grouped by Topic, but they completely
  ignored the topic and were performed on every change
- ChangeProcessors required EventPublisher to be aware of database
  changes

By moving ChangeProcesors out of EventPublisher, and having Publish
accept events instead of changes, EventPublisher no longer needs to
be aware of these things.

Handlers is now only SnapshotHandlers, which are still mapped by Topic.

Also allows us to remove the small 'db' package that had only two types.
They can now be unexported types in state.

The EventPublisher is the central hub of the PubSub system. It is toughly coupled with much of

The two Subscribe cases (with or without index) were also awkwardly split between two packages. By
moving EventPublisher into stream they are now both in the same package (although still in different files).

It is critical that Unsubscribe be called with the same pointer to a

Upgrade go-connlimit to v0.3.0 / return http 429 on too many connections (#8221)
Fixes #7527

I want to highlight this and explain what I think the implications are and make sure we are aware:

* `HTTPConnStateFunc` closes the connection when it is beyond the limit. `Close` does not block.
* `HTTPConnStateFuncWithDefault429Handler(10 * time.Millisecond)` blocks until the following is done (worst case):
  1) `conn.SetDeadline(10*time.Millisecond)` so that
  2) `conn.Write(429error)` is guaranteed to timeout after 10ms, so that the http 429 can be written and 
  3) `conn.Close` can happen

The implication of this change is that accepting any new connection is worst case delayed by 10ms. But only after a client reached the limit already.

Highlights:

- add new endpoint to query for intentions by exact match

- using this endpoint from the CLI instead of the dump+filter approach

- enforcing that OSS can only read/write intentions with a SourceNS or
  DestinationNS field of "default".

- preexisting OSS intentions with now-invalid namespace fields will
  delete those intentions on initial election or for wildcard namespaces
  an attempt will be made to downgrade them to "default" unless one
  exists.

- also allow the '-namespace' CLI arg on all of the intention subcommands

- update lots of docs

Previously, we were only returning a single ListenerPort for a single

expect their services to be contacted over. When no hosts are defined,
we return the default ingress domain for any configured DNS domain.

To show this in the UI, we modify the gateway-services-nodes API to
return a GatewayConfig.Addresses field, which is a list of addresses
over which the specific service can be contacted.

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.

gossip: Ensure that metadata of Consul Service is updated (#7903)
While upgrading servers to a new version, I saw that metadata of
existing servers are not upgraded, so the version and raft meta
is not up to date in catalog.

The only way to do it was to:
 * update Consul server
 * make it leave the cluster, then metadata is accurate

That's because the optimization to avoid updating catalog does
not take into account metadata, so no update on catalog is performed.

ACL Node Identities (#7970)
A Node Identity is very similar to a service identity. Its main targeted use is to allow creating tokens for use by Consul agents that will grant the necessary permissions for all the typical agent operations (node registration, coordinate updates, anti-entropy).

Half of this commit is for golden file based tests of the acl token and role cli output. Another big updates was to refactor many of the tests in agent/consul/acl_endpoint_test.go to use the same style of tests and the same helpers. Besides being less boiler plate in the tests it also uses a common way of starting a test server with ACLs that should operate without any warnings regarding deprecated non-uuid master tokens etc.

Daniel Nephin b7b652e8c9 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.

Daniel Nephin 5ac012dddf 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.

to check for an error.

Daniel Nephin 93d7debbeb agent/service_manager: Pass ctx around

recommends not storing context in a struct field:

> Do not store Contexts inside a struct type; instead, pass a Context
> explicitly to each function that needs it. The Context should be the
> first parameter, typically named ctx...

Sometimes there are good reasons to not follow this recommendation, but
in this case it seems easy enough to follow.

Also moved the ctx argument to be the first in one of the function calls
to follow the same recommendation.

Only pass one hostname via EDS and prefer healthy ones (#8084)
Co-authored-by: Matt Keeler <mkeeler@users.noreply.github.com>

Currently when passing hostname clusters to Envoy, we set each service instance registered with Consul as an LbEndpoint for the cluster.

However, Envoy can only handle one per cluster:
[2020-06-04 18:32:34.094][1][warning][config] [source/common/config/grpc_subscription_impl.cc:87] gRPC config for type.googleapis.com/envoy.api.v2.Cluster rejected: Error adding/updating cluster(s) dc2.internal.ddd90499-9b47-91c5-4616-c0cbf0fc358a.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint, server.dc2.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint

Envoy is currently handling this gracefully by only picking one of the endpoints. However, we should avoid passing multiple to avoid these warning logs.

This PR:

* Ensures we only pass one endpoint, which is tied to one service instance.
* We prefer sending an endpoint which is marked as Healthy by Consul.
* If no endpoints are healthy we emit a warning and skip the cluster.
* If multiple unique hostnames are spread across service instances we emit a warning and let the user know which will be resolved.

Move ingress param to a new endpoint (#8081)
In discussion with team, it was pointed out that query parameters tend
to be filter mechanism, and that semantically the "/v1/health/connect"
endpoint should return "all healthy connect-enabled endpoints (e.g.
could be side car proxies or native instances) for this service so I can
connect with mTLS".

That does not fit an ingress gateway, so we remove the query parameter
and add a new endpoint "/v1/health/ingress" that semantically means
"all the healthy ingress gateway instances that I can connect to
to access this connect-enabled service without mTLS"

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.

Always require Host header values for http services (#7990)
Previously, we did not require the 'service-name.*' host header value
when on a single http service was exposed. However, this allows a user
to get into a situation where, if they add another service to the
listener, suddenly the previous service's traffic might not be routed
correctly. Thus, we always require the Host header, even if there is
only 1 service.

Also, we add the make the default domain matching more restrictive by
matching "service-name.ingress.*" by default. This lines up better with
the namespace case and more accurately matches the Consul DNS value we
expect people to use in this case.

Found using staticcheck.

binary.Write does not accept int types without a size. The error from binary.Write was ignored, so we never saw this error. Casting the data to uint64 produces a correct hash.

Also deprecate the Default{Addr,Port} fields, and prevent them from being encoded. These fields will always be empty and are not used.
Removing these would break backwards compatibility, so they are left in place for now.

checks: when a service does not exists in an alias, consider it failing (#7384)
In current implementation of Consul, check alias cannot determine
if a service exists or not. Because a service without any check
is semantically considered as passing, so when no healthchecks
are found for an agent, the check was considered as passing.

But this make little sense as the current implementation does not
make any difference between:
 * a non-existing service (passing)
 * a service without any check (passing as well)

In order to make it work, we have to ensure that when a check did
not find any healthcheck, the service does indeed exists. If it
does not, lets consider the check as failing.

Enable gateways to resolve hostnames to IPv4 addresses (#7999)
The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option.

If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS.

Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.

agent: handle re-bootstrapping in a secondary datacenter when WAN federation via mesh gateways is configured (#7931)
The main fix here is to always union the `primary-gateways` list with
the list of mesh gateways in the primary returned from the replicated
federation states list. This will allow any replicated (incorrect) state
to be supplemented with user-configured (correct) state in the config
file. Eventually the game of random selection whack-a-mole will pick a
winning entry and re-replicate the latest federation states from the
primary. If the user-configured state is actually the incorrect one,
then the same eventual correct selection process will work in that case,
too.

The secondary fix is actually to finish making wanfed-via-mgws actually
work as originally designed. Once a secondary datacenter has replicated
federation states for the primary AND managed to stand up its own local
mesh gateways then all of the RPCs from a secondary to the primary
SHOULD go through two sets of mesh gateways to arrive in the consul
servers in the primary (one hop for the secondary datacenter's mesh
gateway, and one hop through the primary datacenter's mesh gateway).
This was neglected in the initial implementation. While everything
works, ideally we should treat communications that go around the mesh
gateways as just provided for bootstrapping purposes.

Now we heuristically use the success/failure history of the federation
state replicator goroutine loop to determine if our current mesh gateway
route is working as intended. If it is, we try using the local gateways,
and if those don't work we fall back on trying the primary via the union
of the replicated state and the go-discover configuration flags.

This can be improved slightly in the future by possibly initializing the
gateway choice to local on startup if we already have replicated state.
This PR does not address that improvement.

grpc: use default resolver scheme for grpc dialing (#7617)
Currently checks of type gRPC will emit log messages such as,

    2020/02/12 13:48:22 [INFO] parsed scheme: ""
    2020/02/12 13:48:22 [INFO] scheme "" not registered, fallback to default scheme

Without adding full support for using custom gRPC schemes (maybe that's
right long-term path) we can just supply the default scheme as provided
by the grpc library.

Fix identity resolution on clients and in secondary dcs (#7862)
Previously this happened to be using the method on the Server/Client that was meant to allow the ACLResolver to locally resolve tokens. On Servers that had tokens (primary or secondary dc + token replication) this function would lookup the token from raft and return the ACLIdentity. On clients this was always a noop. We inadvertently used this function instead of creating a new one when we added logging accessor ids for permission denied RPC requests. 

With this commit, a new method is used for resolving the identity properly via the ACLResolver which may still resolve locally in the case of being on a server with tokens but also supports remote token resolution.

In generally we should avoid t.Parallel() as it causes a number of problems with `go test` not reporting failure messages correctly. I encountered one of these problems, which is what prompted this change.  Since `t.Parallel` is not providing any benefit in this package, this commit removes it.

The change was automated with:

Allow ingress gateways to send empty clusters, routes, and listeners (#7795)
This is useful when updating an config entry with no services, and the
expected behavior is that envoy closes all listeners and clusters.

We also allow empty routes because ingress gateways name route
configurations based on the port of the listener, so it is important we
remove any stale routes. Then, if a new listener with an old port is
added, we will not have to deal with stale routes hanging around routing
to the wrong place.

Endpoints are associated with clusters, and thus by deleting the
clusters we don't have to care about sending empty endpoint responses.

Kyle Havlovitz b21cd112e5 Allow ingress gateways to route traffic based on Host header
This commit adds the necessary changes to allow an ingress gateway to
route traffic from a single defined port to multiple different upstream
services in the Consul mesh.

To do this, we now require all HTTP requests coming into the ingress
gateway to specify a Host header that matches "<service-name>.*" in
order to correctly route traffic to the correct service.

- Differentiate multiple listener's route names by port
- Adds a case in xds for allowing default discovery chains to create a
  route configuration when on an ingress gateway. This allows default
  services to easily use host header routing
- ingress-gateways have a single route config for each listener
  that utilizes domain matching to route to different services.

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.

acl: refactor the authmethod.Validator interface (#7760)
This is a collection of refactors that make upcoming PRs easier to digest.

The main change is the introduction of the authmethod.Identity struct.
In the one and only current auth method (type=kubernetes) all of the
trusted identity attributes are both selectable and projectable, so they
were just passed around as a map[string]string.

When namespaces were added, this was slightly changed so that the
enterprise metadata can also come back from the login operation, so
login now returned two fields.

Now with some upcoming auth methods it won't be true that all identity
attributes will be both selectable and projectable, so rather than
update the login function to return 3 pieces of data it seemed worth it
to wrap those fields up and give them a proper name.

Previously, if a blocking query called CheckConnectServiceNodes
before the gateway-services memdb table had any entries,
a nil watchCh would be returned when calling serviceTerminatingGatewayNodes.
This means that the blocking query would not fire if a gateway config entry
was added after the watch started.

In cases where the blocking query started on proxy registration,
the proxy could potentially never become aware of an upstream endpoint
if that upstream was going to be represented by a gateway.

Daniel Nephin 7bc3d09857 Remove deadcode
This UnmarshalJSON was never called. The decode function is passed a map[string]interface
so it has no way of knowing that this function exists.

Tested by adding a panic to this function and watching the tests pass.

I attempted to use this Unmarshal function by passing in the type, however the tests
showed that it does not work. The test was failing to parse the request.

If the performance of this endpoint is indeed critical we can solve the problem by adding
all the fields to the request struct and handling the normalziation without a custom Unmarshal.

Daniel Nephin 1251c01b73 agent/cache: Make all cache options RegisterOptions
Previously the SupportsBlocking option was specified by a method on the
type, and all the other options were specified from RegisterOptions.

This change moves RegisterOptions to a method on the type, and moves
SupportsBlocking into the options struct.

Currently there are only 2 cache-types. So all cache-types can implement
this method by embedding a struct with those predefined values. In the
future if a cache type needs to be registered more than once with different
options it can remove the embedded type and implement the method in a way
that allows for paramaterization.

fix flaky TestReplication_FederationStates test due to race conditions (#7612)
The test had two racy bugs related to memdb references.

The first was when we initially populated data and retained the FederationState objects in a slice. Due to how the `inmemCodec` works these were actually the identical objects passed into memdb.

The second was that the `checkSame` assertion function was reading from memdb and setting the RaftIndexes to zeros to aid in equality checks. This was mutating the contents of memdb which is a no-no.

With this fix, the command:
```
i=0; while /usr/local/bin/go test -count=1 -timeout 30s github.com/hashicorp/consul/agent/consul -run '^(TestReplication_FederationStates)$'; do i=$((i + 1)); printf "$i "; done
```
That used to break on my machine in less than 20 runs is now running 150+ times without any issue.

Might also fix #7575

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.

agent: rewrite checks with proxy address, not local service address (#7518)
Exposing checks is supposed to allow a Consul agent bound to a different
IP address (e.g., in a different Kubernetes pod) to access healthchecks
through the proxy while the underlying service binds to localhost. This
is an important security feature that makes sure no external traffic
reaches the service except through the proxy.

However, as far as I can tell, this is subtly broken in the case where
the Consul agent cannot reach the proxy over localhost.

If a proxy is configured with: `{ LocalServiceAddress: "127.0.0.1",
Checks: true }`, as is typical with a sidecar proxy, the Consul checks
are currently rewritten to `127.0.0.1:<random port>`. A Consul agent
that does not share the loopback address cannot reach this address. Just
to make sure I was not misunderstanding, I tried configuring the proxy
with `{ LocalServiceAddress: "<pod ip>", Checks: true }`. In this case,
while the checks are rewritten as expected and the agent can reach the
dynamic port, the proxy can no longer reach its backend because the
traffic is no longer on the loopback interface.

I think rewriting the checks to use `proxy.Address`, the proxy's own
address, is more correct in this case. That is the IP where the proxy
can be reached, both by other proxies and by a Consul agent running on
a different IP. The local service address should continue to use
`127.0.0.1` in most cases.

proxycfg: support path exposed with non-HTTP2 protocol (#7510)
If a proxied service is a gRPC or HTTP2 service, but a path is exposed
using the HTTP1 or TCP protocol, Envoy should not be configured with
`http2ProtocolOptions` for the cluster backing the path.

A situation where this comes up is a gRPC service whose healthcheck or
metrics route (e.g. for Prometheus) is an HTTP1 service running on
a different port. Previously, if these were exposed either using
`Expose: { Checks: true }` or `Expose: { Paths: ... }`, Envoy would
still be configured to communicate with the path over HTTP2, which would
not work properly.

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"

Daniel Nephin d623dcbd01 Convert the remaining calls to NewTestAgentWithFields
After removing the t.Name() parameter with sed, convert the last few tests which
use a custom name to call NewTestAgentWithFields instead.

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.

Add config entry for terminating gateways (#7545)
This config entry will be used to configure terminating gateways.

It accepts the name of the gateway and a list of services the gateway will represent.

For each service users will be able to specify: its name, namespace, and additional options for TLS origination.

Add config entry/state for Ingress Gateways (#7483)
* Add Ingress gateway config entry and other relevant structs

* Add api package tests for ingress gateways

* Embed EnterpriseMeta into ingress service struct

* Add namespace fields to api module and test consul config write decoding

* Don't require a port for ingress gateways

* Add snakeJSON and camelJSON cases in command test

* Run Normalize on service's ent metadata

Sadly cannot think of a way to test this in OSS.

* Every protocol requires at least 1 service

* Validate ingress protocols

* Update agent/structs/config_entry_gateways.go

And re-add the name to the logger so that log messages from different agents
in a single can be identified.

Daniel Nephin 823295fe2a testing: reduce verbosity of output log
Previously the log output included the test name twice and a long date
format. The test output is already grouped by test, so adding the test
name did not add any new information. The date and time are only useful
to understand elapsed time, so using a short format should provide
succident detail.

Also fixed a bug in NewTestAgentWithFields where nil was returned
instead of the test agent.

It appears to be unused. It looks like it has been around a while,
I geuss at some point we stopped using this method.
