Envoy's SPIFFE certificate validation extension allows for us to
validate against different root certificates depending on the trust
domain of the dialing proxy.
If there are any trust bundles from peers in the config snapshot then we
use the SPIFFE validator as the validation context, rather than the
usual TrustedCA.
The injected validation config includes the local root certificates as
well.
There are a handful of changes in this commit:
* When querying trust bundles for a service we need to be able to
specify the namespace of the service.
* The endpoint needs to track the index because the cache watches use
it.
* Extracted bulk of the endpoint's logic to a state store function
so that index tracking could be tested more easily.
* Removed check for service existence, deferring that sort of work to ACL authz
* Added the cache type
Given that the exported-services config entry can use wildcards, the
precedence for wildcards is handled as with intentions. The most exact
match is the match that applies for any given service. We do not take
the union of all that apply.
Another update that was made was to reflect that only one
exported-services config entry applies to any given service in a
partition. This is a pre-existing constraint that gets enforced by
the Normalize() method on that config entry type.
For mTLS to work between two proxies in peered clusters with different root CAs,
proxies need to configure their outbound listener to use different root certificates
for validation.
Up until peering was introduced proxies would only ever use one set of root certificates
to validate all mesh traffic, both inbound and outbound. Now an upstream proxy
may have a leaf certificate signed by a CA that's different from the dialing proxy's.
This PR makes changes to proxycfg and xds so that the upstream TLS validation
uses different root certificates depending on which cluster is being dialed.
This is the OSS portion of enterprise PRs 1904, 1905, 1906, 1907, 1949,
and 1971.
It replaces the proxycfg manager's direct dependency on the agent cache
with interfaces that will be implemented differently when serving xDS
sessions from a Consul server.

Proxies dialing exporting services need to know the SPIFFE ID of
services dialed so that the upstream's SANs can be validated.
This commit attaches the SPIFFE ID to all connect proxies exported over
the peering stream so that they are available to importing clusters.
The data in the SPIFFE ID cannot be re-constructed in peer clusters
because the partition of exported services is overwritten on imports.
At the end of this test we were trying to ensure that updating a service in the local state causes it to re-register the service with the config manager.
The config manager in the same method will also call RegisteredProxies to determine if any need to be removed. This portion of the test is not attempting to verify that behavior.
Because the test is only blocked waiting for the Register event before it can end and assert all the mock expectations were met, we may not see the call to RegisteredProxies. This is especially apparent when tests are run with the race detector.
As we don’t actually care if that method is executed before the end of the test we can simply transition from expecting it to be called exactly once to a 0 or 1 times assertion.
OSS port of enterprise PR 1822
Includes the necessary changes to the `proxycfg` and `xds` packages to enable
Consul servers to configure arbitrary proxies using catalog data.
Broadly, `proxycfg.Manager` now has public methods for registering,
deregistering, and listing registered proxies — the existing local agent
state-sync behavior has been moved into a separate component that makes use of
these methods.
When an xDS session is started for a proxy service in the catalog, a goroutine
will be spawned to watch the service in the server's state store and
re-register it with the `proxycfg.Manager` whenever it is updated (and clean
it up when the client goes away).

Adds a new query param merge-central-config for use with the below endpoints:
/catalog/service/:service
/catalog/connect/:service
/health/service/:service
/health/connect/:service
If set on the request, the response will include a fully resolved service definition which is merged with the proxy-defaults/global and service-defaults/:service config entries (on-demand style). This is useful to view the full service definition for a mesh service (connect-proxy kind or gateway kind) which might not be merged before being written into the catalog (example: in case of services in the agentless model).
I noticed that the JSON api endpoints for peerings json encodes protobufs directly, rather than converting them into their `api` package equivalents before marshal/unmarshaling them.
I updated this and used `mog` to do the annoying part in the middle.
Other changes:
- the status enum was converted into the friendlier string form of the enum for readability with tools like `curl`
- some of the `api` library functions were slightly modified to match other similar endpoints in UX (cc: @ndhanushkodi )
- peeringRead returns `nil` if not found
- partitions are NOT inferred from the agent's partition (matching 1.11-style logic)
The importing peer will need to know what SNI and SPIFFE name
corresponds to each exported service. Additionally it will need to know
at a high level the protocol in use (L4/L7) to generate the appropriate
connection pool and local metrics.
For replicated connect synthetic entities we edit the `Connect{}` part
of a `NodeService` to have a new section:
{
"PeerMeta": {
"SNI": [
"web.default.default.owt.external.183150d5-1033-3672-c426-c29205a576b8.consul"
],
"SpiffeID": [
"spiffe://183150d5-1033-3672-c426-c29205a576b8.consul/ns/default/dc/dc1/svc/web"
],
"Protocol": "tcp"
}
}
This data is then replicated and saved as-is at the importing side. Both
SNI and SpiffeID are slices for now until I can be sure we don't need
them for how mesh gateways will ultimately work.

Occasionally we had seen the TestWatchServers_ACLToken_PermissionDenied be flagged as flaky in circleci. This change should fix that.
Why it fixes it is complicated. The test was failing with a panic when a mocked ACL Resolver was being called more times than expected. I struggled for a while to determine how that could be. This test should call authorize once and only once and the error returned should cause the stream to be terminated and the error returned to the gRPC client. Another oddity was no amount of running this test locally seemed to be able to reproduce the issue. I ran the test hundreds of thousands of time and it always passed.
It turns out that there is nothing wrong with the test. It just so happens that the panic from unexpected invocation of a mocked call happened during the test but was caused by a previous test (specifically the TestWatchServers_StreamLifecycle test)
The stream from the previous test remained open after all the test Cleanup functions were run and it just so happened that when the EventPublisher eventually picked up that the context was cancelled during cleanup, it force closes all subscriptions which causes some loops to be re-entered and the streams to be reauthorized. Its that looping in response to forced subscription closures that causes the mock to eventually panic. All the components, publisher, server, client all operate based on contexts. We cancel all those contexts but there is no syncrhonous way to know when they are stopped.
We could have implemented a syncrhonous stop but in the context of an actual running Consul, context cancellation + async stopping is perfectly fine. What we (Dan and I) eventually thought was that the behavior of grpc streams such as this when a server was shutting down wasn’t super helpful. What we would want is for a client to be able to distinguish between subscription closed because something may have changed requiring re-authentication and subscription closed because the server is shutting down. That way we can send back appropriate error messages to detail that the server is shutting down and not confuse users with potentially needing to resubscribe.
So thats what this PR does. We have introduced a shutting down state to our event subscriptions and the various streaming gRPC services that rely on the event publisher will all just behave correctly and actually stop the stream (not attempt transparent reauthorization) if this particular error is the one we get from the stream. Additionally the error that gets transmitted back through gRPC when this does occur indicates to the consumer that the server is going away. That is more helpful so that a client can then attempt to reconnect to another server.
OSS portion of enterprise PR 1857.
This removes (most) references to the `cache.UpdateEvent` type in the
`proxycfg` package.
As we're going to be direct usage of the agent cache with interfaces that
can be satisfied by alternative server-local datasources, it doesn't make
sense to depend on this type everywhere anymore (particularly on the
`state.ch` channel).
We also plan to extract `proxycfg` out of Consul into a shared library in
the future, which would require removing this dependency.
Aside from a fairly rote find-and-replace, the main change is that the
`cache.Cache` and `health.Client` types now accept a callback function
parameter, rather than a `chan<- cache.UpdateEvents`. This allows us to
do the type conversion without running another goroutine.
- Introduce a new telemetry configurable parameter retry_failed_connection. User can set the value to true to let consul agent continue its start process on failed connection to datadog server. When set to false, agent will stop on failed start. The default behavior is true.

Treat each exported service as a "discovery chain" and replicate one
synthetic CheckServiceNode for each chain and remote mesh gateway.
The health will be a flattened generated check of the checks for that
mesh gateway node.
By changing to use WatchCtx we will actually block for changes to the peering list. WatchCh creates a goroutine to collect errors from WatchCtx and returns immediately.
The existing behavior wouldn't result in a tight loop because of the rate limiting in the surrounding function, but it would still lead to more work than is necessary.
Changes include:
- Add diagrams of the operation of different consistency modes
- Note that only stale reads benefit from horizontal scaling
- Increase scannability with headings
- Document consistency mode defaults and how to override for
DNS and HTTP API interfaces
- Document X-Consul-Effective-Consistency response header
Changes to how the version string was handled created small regression with the release of consul 1.12.0 enterprise.
Many tools use the Config:Version field reported by the agent/self resource to determine whether Consul is an enterprise or OSS instance, expect something like 1.12.0+ent for enterprise and simply 1.12.0 for OSS. This was accidentally broken during the runup to 1.12.x
This work fixes the value returned by both the self endpoint in ["Config"]["Version"] and the metrics consul.version field.

Add validation to ensure connect native services have a port or socketpath specified on catalog registration.
This was the only missing piece to ensure all mesh services are validated for a port (or socketpath) specification on catalog registration.
* Support vault namespaces in connect CA
Follow on to some missed items from #12655
From an internal ticket "Support standard "Vault namespace in the
path" semantics for Connect Vault CA Provider"
Vault allows the namespace to be specified as a prefix in the path of
a PKI definition, but our usage of the Vault API includes calls that
don't support a namespaced key. In particular the sys.* family of
calls simply appends the key, instead of prefixing the namespace in
front of the path.
Unfortunately it is difficult to reliably parse a path with a
namespace; only vault knows what namespaces are present, and the '/'
separator can be inside a key name, as well as separating path
elements. This is in use in the wild; for example
'dc1/intermediate-key' is a relatively common naming schema.
Instead we add two new fields: RootPKINamespace and
IntermediatePKINamespace, which are the absolute namespace paths
'prefixed' in front of the respective PKI Paths.

Description
Add x-fowarded-client-cert information on trusted incoming connections.
Envoy provides support forwarding and annotating the
x-forwarded-client-cert header via the forward_client_cert_details
set_current_client_cert_details filter fields. It would be helpful for
consul to support this directly in its config. The escape hatches are
a bit cumbersome for this purpose.
This has been implemented on incoming connections to envoy. Outgoing
(from the local service through the sidecar) will not have a
certificate, and so are left alone.
A service on an incoming connection will now get headers something like this:
```

Closes#12852
The primary bug here is in the streaming subsystem that makes the overall v1/health/service/:service request behave incorrectly when servicing a blocking request with a filter provided.
There is a secondary non-streaming bug being fixed here that is much less obvious related to when to update the `reply` variable in a `blockingQuery` evaluation. It is unlikely that it is triggerable in practical environments and I could not actually get the bug to manifest, but I fixed it anyway while investigating the original issue.
Simple reproduction (streaming):
1. Register a service with a tag.
curl -sL --request PUT 'http://localhost:8500/v1/agent/service/register' \
--header 'Content-Type: application/json' \
--data-raw '{ "ID": "ID1", "Name": "test", "Tags":[ "a" ], "EnableTagOverride": true }'
2. Do an initial filter query that matches on the tag.
curl -sLi --get 'http://localhost:8500/v1/health/service/test' --data-urlencode 'filter=a in Service.Tags'
3. Note you get one result. Use the `X-Consul-Index` header to establish
a blocking query in another terminal, this should not return yet.
curl -sLi --get 'http://localhost:8500/v1/health/service/test?index=$INDEX' --data-urlencode 'filter=a in Service.Tags'
4. Re-register that service with a different tag.
curl -sL --request PUT 'http://localhost:8500/v1/agent/service/register' \
--header 'Content-Type: application/json' \
--data-raw '{ "ID": "ID1", "Name": "test", "Tags":[ "b" ], "EnableTagOverride": true }'
5. Your blocking query from (3) should return with a header
`X-Consul-Query-Backend: streaming` and empty results if it works
correctly `[]`.
Attempts to reproduce with non-streaming failed (where you add `&near=_agent` to the read queries and ensure `X-Consul-Query-Backend: blocking-query` shows up in the results).

Whenever autopilot updates its state it notifies Consul. That notification will then trigger Consul to extract out the ready server information. If the ready servers have changed, then an event will be published to notify any subscribers of the full set of ready servers.
All these ready server event things are contained within an autopilotevents package instead of the consul package to make importing them into the grpc related packages possible
Introduces a gRPC endpoint for signing Connect leaf certificates. It's also
the first of the public gRPC endpoints to perform leader-forwarding, so
establishes the pattern of forwarding over the multiplexed internal RPC port.
Previously we had 1 EventPublisher per state.Store. When a state store was closed/abandoned such as during a consul snapshot restore, this had the behavior of force closing subscriptions for that topic and evicting event snapshots from the cache.
The intention of this commit is to keep all that behavior. To that end, the shared EventPublisher now supports the ability to refresh a topic. That will perform the force close + eviction. The FSM upon abandoning the previous state.Store will call RefreshTopic for all the topics with events generated by the state.Store.
Just like standard upstreams the order of applicability in descending precedence:
1. caller's `service-defaults` upstream override for destination
2. caller's `service-defaults` upstream defaults
3. destination's `service-resolver` ConnectTimeout
4. system default of 5s

* Avoid doing list of /sys/mounts
From an internal ticket "Support standard "Vault namespace in the path" semantics for Connect Vault CA Provider"
Vault allows the namespace to be specified as a prefix in the path of
a PKI definition, but this doesn't currently work for
```IntermediatePKIPath``` specifications, because we attempt to list
all of the paths to check if ours is already defined. This doesn't
really work in a namespaced world.
This changes the IntermediatePKIPath code to follow the same pattern
as the root key, where we directly get the key rather than listing.
This code is difficult to write automated tests for because it relies
on features of Vault Enterprise, which isn't currently part of our
test framework, so it was tested manually.

This adds an aws-iam auth method type which supports authenticating to Consul using AWS IAM identities.
Co-authored-by: R.B. Boyer <4903+rboyer@users.noreply.github.com>
- `tls.incoming`: applies to the inbound mTLS targeting the public
listener on `connect-proxy` and `terminating-gateway` envoy instances
- `tls.outgoing`: applies to the outbound mTLS dialing upstreams from
`connect-proxy` and `ingress-gateway` envoy instances
Fixes#11966
* Fix leaked Vault LifetimeRenewers
When the Vault CA Provider is reconfigured we do not stop the
LifetimeRenewers which can cause them to leak until the Consul processes
recycles. On Configure execute stopWatcher if it exists and is not nil
before starting a new renewal
* Add jitter before restarting the LifetimeWatcher
If we fail to login to Vault or our token is no longer valid we can
overwhelm a Vault instance with many requests very quickly by restarting
the LifetimeWatcher. Before restarting the LifetimeWatcher provide a
backoff time of 1 second or less.

Looks like something got munged at some point. Not sure how it slipped in, but my best guess is that because TestTxn_Apply_ACLDeny is marked flaky we didn't block merge because it failed.

Part of #12481
Signed-off-by: Mark Anderson <manderson@hashicorp.com>
Introduces the capability to configure TLS differently for Consul's
listeners/ports (i.e. HTTPS, gRPC, and the internal multiplexed RPC
port) which is useful in scenarios where you may want the HTTPS or
gRPC interfaces to present a certificate signed by a well-known/public
CA, rather than the certificate used for internal communication which
must have a SAN in the form `server.<dc>.consul`.
Give the user a hint that they might be doing something wrong if their GET
request has a non-empty body, which can easily happen using curl's
--data-urlencode if specifying request type via "--request GET" rather than
"--get". See https://github.com/hashicorp/consul/issues/11471.
Currently the config_entry.go subsystem delegates authorization decisions via the ConfigEntry interface CanRead and CanWrite code. Unfortunately this returns a true/false value and loses the details of the source.
This is not helpful, especially since it the config subsystem can be more complex to understand, since it covers so many domains.
This refactors CanRead/CanWrite to return a structured error message (PermissionDenied or the like) with more details about the reason for denial.

Prior to this PR for the envoy xDS golden tests in the agent/xds package we
were hand-creating a proxycfg.ConfigSnapshot structure in the proper format for
input to the xDS generator. Over time this intermediate structure has gotten
trickier to build correctly for the various tests.
This PR proposes to switch to using the existing mechanism for turning a
structs.NodeService and a sequence of cache.UpdateEvent copies into a
proxycfg.ConfigSnapshot, as that is less error prone to construct and aligns
more with how the data arrives.
NOTE: almost all of this is in test-related code. I tried super hard to craft
correct event inputs to get the golden files to be the same, or similar enough
after construction to feel ok that i recreated the spirit of the original test
cases.
Improves tests from #12362
These tests try to setup the following concurrent scenario:
1. (goroutine 1) execute read RPC with index=0
2. (goroutine 1) get response from (1) @ index=10
3. (goroutine 1) execute read RPC with index=10 and block
4. (goroutine 2) WHILE (3) is blocking, start slamming the system with stray writes that will cause the WatchSet to wakeup
5. (goroutine 2) after doing all writes, shut down the reader above
6. (goroutine 1) stops reading, double checks that it only ever woke up once (from 1)
Minor fix for behavior in #12362
IsDefault sometimes returns true even if there was a proxy-defaults or service-defaults config entry that was consulted. This PR fixes that.
