Implements the gRPC middleware for rate-limiting as a tap.ServerInHandle
function (executed before the request is unmarshaled).
Mappings between gRPC methods and their operation type are generated by
a protoc plugin introduced by #15564.
Adds a no-op implementation of the rate-limit handler and exposes
it on the consul.Server struct.
It allows us to start working on the net/rpc and gRPC interceptors
and config (re)loading logic, without having to implement the full
handler up-front.

Fix local mesh gateway with peering discovery chains.
Prior to this patch, discovery chains with peers would not
properly honor the mesh gateway mode for two reasons.
1. An incorrect target upstream ID was used to lookup the
mesh gateway mode. To fix this, the parent upstream uid is
now used instead of the discovery-chain-target-uid to find
the intended mesh gateway mode.
2. The watch for local mesh gateways was never initialized
for discovery chains. To fix this, the discovery chains are
now scanned, and a local GW watch is spawned if: the mesh
gateway mode is local and the target is a peering connection.
It turns out that by default the dev mode vault server will attempt to interact with the
filesystem to store the provided root token. If multiple vault instances are running
they'll all awkwardly share the filesystem and if timing results in one server stopping
while another one is starting then the starting one will error with:
Error initializing Dev mode: rename /home/circleci/.vault-token.tmp /home/circleci/.vault-token: no such file or directory
This change uses `-dev-no-store-token` to bypass that source of flakes. Also the
stdout/stderr from the vault process is included if the test fails.
The introduction of more `t.Parallel` use in https://github.com/hashicorp/consul/pull/15669
increased the likelihood of this failure, but any of the tests with multiple vaults in use
(or running multiple package tests in parallel that all use vault) were eventually going
to flake on this.
All of the current integration tests where Vault is the Connect CA now use non-root tokens for the test. This helps us detect privilege changes in the vault model so we can keep our guides up to date.
One larger change was that the RenewIntermediate function got refactored slightly so it could be used from a test, rather than the large duplicated function we were testing in a test which seemed error prone.
The fix outlined and merged in #15253 fixed the issue as it occurs in the primary
DC. There is a similar issue that arises when vault is used as the Connect CA in a
secondary datacenter that is fixed by this PR.
Additionally: this PR adds support to run the existing suite of vault related integration
tests against the last 4 versions of vault (1.9, 1.10, 1.11, 1.12)

During peer stream replication we flatten checks from the source cluster and build one thin overall check to hide the irrelevant details from the consuming cluster. This flattening logic did correctly flip to non-passing if there were any non-passing checks, but WHICH status it got during that was random (warn/error).
Also it didn't represent "maintenance" operations. There is an api package call AggregatedStatus which more correctly flattened check statuses.
This PR replicated the more complete logic into the peer stream package.
* Remove log line about server mgmt token init
Currently the server management token is only being bootstrapped in the
primary datacenter. That means that servers on the secondary datacenter
will never have this token available, and would log this line any time a
token is resolved.
Bootstrapping the token in secondary datacenters will be done in a
follow-up.
* Add changelog entry
Consul used to rely on implicit issuer selection when calling Vault endpoints to issue new CSRs. Vault 1.11+ changed that behavior, which caused Consul to check the wrong (previous) issuer when renewing its Intermediate CA. This patch allows Consul to explicitly set a default issuer when it detects that the response from Vault is 1.11+.

There are a few changes that needed to be made to to handle authorizing
reads for imported data:
- If the data was imported from a peer we should not attempt to read the
data using the traditional authz rules. This is because the name of
services/nodes in a peer cluster are not equivalent to those of the
importing cluster.
- If the data was imported from a peer we need to check whether the
token corresponds to a service, meaning that it has service:write
permissions, or to a local read only token that can read all
nodes/services in a namespace.
This required changes at the policyAuthorizer level, since that is the
only view available to OSS Consul, and at the enterprise
partition/namespace level.

Prevent serving TLS via ports.grpc
We remove the ability to run the ports.grpc in TLS mode to avoid
confusion and to simplify configuration. This breaking change
ensures that any user currently using ports.grpc in an encrypted
mode will receive an error message indicating that ports.grpc_tls
must be explicitly used.
The suggested action for these users is to simply swap their ports.grpc
to ports.grpc_tls in the configuration file. If both ports are defined,
or if the user has not configured TLS for grpc, then the error message
will not be printed.

* Fix mesh gateway proxy-defaults not affecting upstreams.
* Clarify distinction with upstream settings
Top-level mesh gateway mode in proxy-defaults and service-defaults gets
merged into NodeService.Proxy.MeshGateway, and only gets merged with
the mode attached to an an upstream in proxycfg/xds.
* Fix mgw mode usage for peered upstreams
There were a couple issues with how mgw mode was being handled for
peered upstreams.
For starters, mesh gateway mode from proxy-defaults
and the top-level of service-defaults gets stored in
NodeService.Proxy.MeshGateway, but the upstream watch for peered data
was only considering the mesh gateway config attached in
NodeService.Proxy.Upstreams[i]. This means that applying a mesh gateway
mode via global proxy-defaults or service-defaults on the downstream
would not have an effect.
Separately, transparent proxy watches for peered upstreams didn't
consider mesh gateway mode at all.
This commit addresses the first issue by ensuring that we overlay the
upstream config for peered upstreams as we do for non-peered. The second
issue is addressed by re-using setupWatchesForPeeredUpstream when
handling transparent proxy updates.
Note that for transparent proxies we do not yet support mesh gateway
mode per upstream, so the NodeService.Proxy.MeshGateway mode is used.
* Fix upstream mesh gateway mode handling in xds
This commit ensures that when determining the mesh gateway mode for
peered upstreams we consider the NodeService.Proxy.MeshGateway config as
a baseline.
In absense of this change, setting a mesh gateway mode via
proxy-defaults or the top-level of service-defaults will not have an
effect for peered upstreams.
* Merge service/proxy defaults in cfg resolver
Previously the mesh gateway mode for connect proxies would be
merged at three points:
1. On servers, in ComputeResolvedServiceConfig.
2. On clients, in MergeServiceConfig.
3. On clients, in proxycfg/xds.
The first merge returns a ServiceConfigResponse where there is a
top-level MeshGateway config from proxy/service-defaults, along with
per-upstream config.
The second merge combines per-upstream config specified at the service
instance with per-upstream config specified centrally.
The third merge combines the NodeService.Proxy.MeshGateway
config containing proxy/service-defaults data with the per-upstream
mode. This third merge is easy to miss, which led to peered upstreams
not considering the mesh gateway mode from proxy-defaults.
This commit removes the third merge, and ensures that all mesh gateway
config is available at the upstream. This way proxycfg/xds do not need
to do additional overlays.
* Ensure that proxy-defaults is considered in wc
Upstream defaults become a synthetic Upstream definition under a
wildcard key "*". Now that proxycfg/xds expect Upstream definitions to
have the final MeshGateway values, this commit ensures that values from
proxy-defaults/service-defaults are the default for this synthetic
upstream.
* Add changelog.

Previously, the MergeNodeServiceWithCentralConfig method accepted a
ServiceSpecificRequest argument, of which only the Datacenter and
QueryOptions fields were used.
Digging a little deeper, it turns out these fields were only passed
down to the ComputeResolvedServiceConfig method (through the
ServiceConfigRequest struct) which didn't actually use them.
As such, not all call-sites passed a valid ServiceSpecificRequest
so it's safer to remove the argument altogether to prevent future
changes from depending on it.

Allow for some message duplication in subscription events during assertions.
I'm pretty sure the subscriptions machinery allows for messages to occasionally
be duplicated instead of dropping them, as a once-and-only-once queue is a pipe
dream and you have to pick one of the other two options.
* ingress-gateways: don't log error when registering gateway
Previously, when an ingress gateway was registered without a
corresponding ingress gateway config entry, an error was logged
because the watch on the config entry returned a nil result.
This is expected so don't log an error.
* autoencrypt: helpful error for clients with wrong dc
If clients have set a different datacenter than the servers they're
connecting with for autoencrypt, give a helpful error message.
This continues the work done in #14908 where a crude solution to prevent a
goroutine leak was implemented. The former code would launch a perpetual
goroutine family every iteration (+1 +1) and the fixed code simply caused a
new goroutine family to first cancel the prior one to prevent the
leak (-1 +1 == 0).
This PR refactors this code completely to:
- make it more understandable
- remove the recursion-via-goroutine strangeness
- prevent unnecessary RPC fetches when the prior one has errored.
The core issue arose from a conflation of the entry.Fetching field to mean:
- there is an RPC (blocking query) in flight right now
- there is a goroutine running to manage the RPC fetch retry loop
The problem is that the goroutine-leak-avoidance check would treat
Fetching like (2), but within the body of a goroutine it would flip that
boolean back to false before the retry sleep. This would cause a new
chain of goroutines to launch which #14908 would correct crudely.
The refactored code uses a plain for-loop and changes the semantics
to track state for "is there a goroutine associated with this cache entry"
instead of the former.
We use a uint64 unique identity per goroutine instead of a boolean so
that any orphaned goroutines can tell when they've been replaced when
the expiry loop deletes a cache entry while the goroutine is still running
and is later replaced.
To support Destinations on the service-defaults (for tproxy with terminating gateway), we need to now also make servers watch service-defaults config entries.
This commit updates the establish endpoint to bubble up a 403 status
code to callers when the establishment secret from the token is invalid.
This is a signal that a new peering token must be generated.

Fix an issue where rpc_hold_timeout was being used as the timeout for non-blocking queries. Users should be able to tune read timeouts without fiddling with rpc_hold_timeout. A new configuration `rpc_read_timeout` is created.
Refactor some implementation from the original PR 11500 to remove the misleading linkage between RPCInfo's timeout (used to retry in case of certain modes of failures) and the client RPC timeouts.
There is a bug in the error handling code for the Agent cache subsystem discovered:
1. NotifyCallback calls notifyBlockingQuery which calls getWithIndex in
a loop (which backs off on-error up to 1 minute)
2. getWithIndex calls fetch if there’s no valid entry in the cache
3. fetch starts a goroutine which calls Fetch on the cache-type, waits
for a while (again with backoff up to 1 minute for errors) and then
calls fetch to trigger a refresh
The end result being that every 1 minute notifyBlockingQuery spawns an
ancestry of goroutines that essentially lives forever.
This PR ensures that the goroutine started by `fetch` cancels any prior
goroutine spawned by the same line for the same key.
In isolated testing where a cache type was tweaked to indefinitely
error, this patch prevented goroutine counts from skyrocketing.
In practice this was masked by #14956 and was only uncovered fixing the
other bug.
go test ./agent -run TestAgentConnectCALeafCert_goodNotLocal
would fail when only #14956 was fixed.
Adds a user-configurable rate limiter to proxycfg snapshot delivery,
with a default limit of 250 updates per second.
This addresses a problem observed in our load testing of Consul
Dataplane where updating a "global" resource such as a wildcard
intention or the proxy-defaults config entry could starve the Raft or
Memberlist goroutines of CPU time, causing general cluster instability.
Replaces the reflection-based implementation of proxycfg's
ConfigSnapshot.Clone with code generated by deep-copy.
While load testing server-based xDS (for consul-dataplane) we discovered
this method is extremely expensive. The ConfigSnapshot struct, directly
or indirectly, contains a copy of many of the structs in the agent/structs
package, which creates a large graph for copystructure.Copy to traverse
at runtime, on every proxy reconfiguration.
When peering through mesh gateways we expect outbound dials to peer
servers to flow through the local mesh gateway addresses.
Now when establishing a peering we get a list of dial addresses as a
ring buffer that includes local mesh gateway addresses if the local DC
is configured to peer through mesh gateways. The ring buffer includes
the mesh gateway addresses first, but also includes the remote server
addresses as a fallback.
This fallback is present because it's possible that direct egress from
the servers may be allowed. If not allowed then the leader will cycle
back to a mesh gateway address through the ring.
When attempting to dial the remote servers we retry up to a fixed
timeout. If using mesh gateways we also have an initial wait in
order to allow for the mesh gateways to configure themselves.
Note that if we encounter a permission denied error we do not retry
since that error indicates that the secret in the peering token is
invalid.
memdb's `WatchCh` method creates a goroutine that will publish to the
returned channel when the watchset is triggered or the given context
is canceled. Although this is called out in its godoc comment, it's
not obvious that this method creates a goroutine who's lifecycle you
need to manage.
In the xDS capacity controller, we were calling `WatchCh` on each
iteration of the control loop, meaning the number of goroutines would
grow on each autopilot event until there was catalog churn.
In the catalog config source, we were calling `WatchCh` with the
background context, meaning that the goroutine would keep running after
the sync loop had terminated.
Adds another datasource for proxycfg.HTTPChecks, for use on server agents. Typically these checks are performed by local client agents and there is no equivalent of this in agentless (where servers configure consul-dataplane proxies).
Hence, the data source is mostly a no-op on servers but in the case where the service is present within the local state, it delegates to the cache data source.
This commit adds a monotonically increasing nonce to include in peering
replication response messages. Every ack/nack from the peer handling a
response will include this nonce, allowing to correlate the ack/nack
with a specific resource.
At the moment nothing is done with the nonce when it is received. In the
future we may want to add functionality such as retries on NACKs,
depending on the class of error.

Preivously when alias check was removed it would not be stopped nor
cleaned up from the associated aliasChecks map.
This means that any time an alias check was deregistered we would
leak a goroutine for CheckAlias.run() because the stopCh would never
be closed.
This issue mostly affects service mesh deployments on platforms where
the client agent is mostly static but proxy services come and go
regularly, since by default sidecars are registered with an alias check.

A previous commit introduced an internally-managed server certificate
to use for peering-related purposes.
Now the peering token has been updated to match that behavior:
- The server name matches the structure of the server cert
- The CA PEMs correspond to the Connect CA
Note that if Conect is disabled, and by extension the Connect CA, we
fall back to the previous behavior of returning the manually configured
certs and local server SNI.
Several tests were updated to use the gRPC TLS port since they enable
Connect by default. This means that the peering token will embed the
Connect CA, and the dialer will expect a TLS listener.
