This commit adds the PrioritizeByLocality field to both proxy-config
and service-resolver config entries for locality-aware routing. The
field is currently intended for enterprise only, and will be used to
enable prioritization of service-mesh connections to services based
on geographical region / zone.

Prior to this change, peer services would be targeted by service-default
overrides as long as the new `peer` field was not found in the config entry.
This commit removes that deprecated backwards-compatibility behavior. Now
it is necessary to specify the `peer` field in order for upstream overrides
to apply to a peer upstream.
The old setting of 24 hours was not enough time to deal with an expiring certificates. This change ups it to 28 days OR 40% of the full cert duration, whichever is shorter. It also adds details to the log message to indicate which certificate it is logging about and a suggested action.
Currently, if an acceptor peer deletes a peering the dialer's peering
will eventually get to a "terminated" state. If the two clusters need to
be re-peered the acceptor will re-generate the token but the dialer will
encounter this error on the call to establish:
"failed to get addresses to dial peer: failed to refresh peer server
addresses, will continue to use initial addresses: there is no active
peering for "<<<ID>>>""
This is because in `exchangeSecret().GetDialAddresses()` we will get an
error if fetching addresses for an inactive peering. The peering shows
up as inactive at this point because of the existing terminated state.
Rather than checking whether a peering is active we can instead check
whether it was deleted. This way users do not need to delete terminated
peerings in the dialing cluster before re-establishing them.
* Rename Intermediate cert references to LeafSigningCert
Within the Consul CA subsystem, the term "Intermediate"
is confusing because the meaning changes depending on
provider and datacenter (primary vs secondary). For
example, when using the Consul CA the "ActiveIntermediate"
may return the root certificate in a primary datacenter.
At a high level, we are interested in knowing which
CA is responsible for signing leaf certs, regardless of
its position in a certificate chain. This rename makes
the intent clearer.
* Move provider state check earlier
* Remove calls to GenerateLeafSigningCert
GenerateLeafSigningCert (formerly known
as GenerateIntermediate) is vestigial in
non-Vault providers, as it simply returns
the root certificate in primary
datacenters.
By folding Vault's intermediate cert logic
into `GenerateRoot` we can encapsulate
the intermediate cert handling within
`newCARoot`.
* Move GenerateLeafSigningCert out of PrimaryProvidder
Now that the Vault Provider calls
GenerateLeafSigningCert within
GenerateRoot, we can remove the method
from all other providers that never
used it in a meaningful way.
* Add test for IntermediatePEM
* Rename GenerateRoot to GenerateCAChain
"Root" was being overloaded in the Consul CA
context, as different providers and configs
resulted in a single root certificate or
a chain originating from an external trusted
CA. Since the Vault provider also generates
intermediates, it seems more accurate to
call this a CAChain.
This PR adds the sameness-group field to exported-service
config entries, which allows for services to be exported
to multiple destination partitions / peers easily.
* Use merge of enterprise meta's rather than new custom method
* Add merge logic for tcp routes
* Add changelog
* Normalize certificate refs on gateways
* Fix infinite call loop
* Explicitly call enterprise meta
This commit swaps the partition field to the local partition for
discovery chains targeting peers. Prior to this change, peer upstreams
would always use a value of default regardless of which partition they
exist in. This caused several issues in xds / proxycfg because of id
mismatches.
Some prior fixes were made to deal with one-off id mismatches that this
PR also cleans up, since they are no longer needed.

This commit fixes an issue where trust bundles could not be read
by services in a non-default namespace, unless they had excessive
ACL permissions given to them.
Prior to this change, `service:write` was required in the default
namespace in order to read the trust bundle. Now, `service:write`
to a service in any namespace is sufficient.
If a CA config update did not cause a root change, the codepath would return early and skip some steps which preserve its intermediate certificates and signing key ID. This commit re-orders some code and prevents updates from generating new intermediate certificates.
This commit adds a sameness-group config entry to the API and structs packages. It includes some validation logic and a new memdb index that tracks the default sameness-group for each partition. Sameness groups will simplify the effort of managing failovers / intentions / exports for peers and partitions.
Note that this change purely to introduce the configuration entry and does not include the full functionality of sameness-groups.

Add a new envoy flag: "envoy_hcp_metrics_bind_socket_dir", a directory
where a unix socket will be created with the name
`<namespace>_<proxy_id>.sock` to forward Envoy metrics.
If set, this will configure:
- In bootstrap configuration a local stats_sink and static cluster.
These will forward metrics to a loopback listener sent over xDS.
- A dynamic listener listening at the socket path that the previously
defined static cluster is sending metrics to.
- A dynamic cluster that will forward traffic received at this listener
to the hcp-metrics-collector service.
Reasons for having a static cluster pointing at a dynamic listener:
- We want to secure the metrics stream using TLS, but the stats sink can
only be defined in bootstrap config. With dynamic listeners/clusters
we can use the proxy's leaf certificate issued by the Connect CA,
which isn't available at bootstrap time.
- We want to intelligently route to the HCP collector. Configuring its
addreess at bootstrap time limits our flexibility routing-wise. More
on this below.
Reasons for defining the collector as an upstream in `proxycfg`:
- The HCP collector will be deployed as a mesh service.
- Certificate management is taken care of, as mentioned above.
- Service discovery and routing logic is automatically taken care of,
meaning that no code changes are required in the xds package.
- Custom routing rules can be added for the collector using discovery
chain config entries. Initially the collector is expected to be
deployed to each admin partition, but in the future could be deployed
centrally in the default partition. These config entries could even be
managed by HCP itself.
Add support for using existing vault auto-auth configurations as the
provider configuration when using Vault's CA provider with AliCloud.
AliCloud requires 2 extra fields to enable it to use STS (it's preferred
auth setup). Our vault-plugin-auth-alicloud package contained a method
to help generate them as they require you to make an http call to
a faked endpoint proxy to get them (url and headers base64 encoded).
Receiving an "acl not found" error from an RPC in the agent cache and the
streaming/event components will cause any request loops to cease under the
assumption that they will never work again if the token was destroyed. This
prevents log spam (#14144, #9738).
Unfortunately due to things like:
- authz requests going to stale servers that may not have witnessed the token
creation yet
- authz requests in a secondary datacenter happening before the tokens get
replicated to that datacenter
- authz requests from a primary TO a secondary datacenter happening before the
tokens get replicated to that datacenter
The caller will get an "acl not found" *before* the token exists, rather than
just after. The machinery added above in the linked PRs will kick in and
prevent the request loop from looping around again once the tokens actually
exist.
For `consul-dataplane` usages, where xDS is served by the Consul servers
rather than the clients ultimately this is not a problem because in that
scenario the `agent/proxycfg` machinery is on-demand and launched by a new xDS
stream needing data for a specific service in the catalog. If the watching
goroutines are terminated it ripples down and terminates the xDS stream, which
CDP will eventually re-establish and restart everything.
For Consul client usages, the `agent/proxycfg` machinery is ahead-of-time
launched at service registration time (called "local" in some of the proxycfg
machinery) so when the xDS stream comes in the data is already ready to go. If
the watching goroutines terminate it should terminate the xDS stream, but
there's no mechanism to re-spawn the watching goroutines. If the xDS stream
reconnects it will see no `ConfigSnapshot` and will not get one again until
the client agent is restarted, or the service is re-registered with something
changed in it.
This PR fixes a few things in the machinery:
- there was an inadvertent deadlock in fetching snapshot from the proxycfg
machinery by xDS, such that when the watching goroutine terminated the
snapshots would never be fetched. This caused some of the xDS machinery to
get indefinitely paused and not finish the teardown properly.
- Every 30s we now attempt to re-insert all locally registered services into
the proxycfg machinery.
- When services are re-inserted into the proxycfg machinery we special case
"dead" ones such that we unilaterally replace them rather that doing that
conditionally.
Adds support for the approle auth-method. Only handles using the approle
role/secret to auth and it doesn't support the agent's extra management
configuration options (wrap and delete after read) as they are not
required as part of the auth (ie. they are vault agent things).
* Fix issue where terminating gateway service resolvers weren't properly cleaned up
* Add integration test for cleaning up resolvers
* Add changelog entry
* Use state test and drop integration test
* Leverage ServiceResolver ConnectTimeout for route timeouts to make TerminatingGateway upstream timeouts configurable
* Regenerate golden files

Adds support for a jwt token in a file. Simply reads the file and sends
the read in jwt along to the vault login.
It also supports a legacy mode with the jwt string being passed
directly. In which case the path is made optional.
Does the required dance with the local HTTP endpoint to get the required
data for the jwt based auth setup in Azure. Keeps support for 'legacy'
mode where all login data is passed on via the auth methods parameters.
Refactored check for hardcoded /login fields.
Registering gRPC balancers is thread-unsafe because they are stored in a
global map variable that is accessed without holding a lock. Therefore,
it's expected that balancers are registered _once_ at the beginning of
your program (e.g. in a package `init` function) and certainly not after
you've started dialing connections, etc.
> NOTE: this function must only be called during initialization time
> (i.e. in an init() function), and is not thread-safe.
While this is fine for us in production, it's challenging for tests that
spin up multiple agents in-memory. We currently register a balancer per-
agent which holds agent-specific state that cannot safely be shared.
This commit introduces our own registry that _is_ thread-safe, and
implements the Builder interface such that we can call gRPC's `Register`
method once, on start-up. It uses the same pattern as our resolver
registry where we use the dial target's host (aka "authority"), which is
unique per-agent, to determine which builder to use.
Prior to this commit, all peer services were transmitted as connect-enabled
as long as a one or more mesh-gateways were healthy. With this change, there
is now a difference between typical services and connect services transmitted
via peering.
A service will be reported as "connect-enabled" as long as any of these
conditions are met:
1. a connect-proxy sidecar is registered for the service name.
2. a connect-native instance of the service is registered.
3. a service resolver / splitter / router is registered for the service name.
4. a terminating gateway has registered the service.
Protobuf Refactoring for Multi-Module Cleanliness
This commit includes the following:
Moves all packages that were within proto/ to proto/private
Rewrites imports to account for the packages being moved
Adds in buf.work.yaml to enable buf workspaces
Names the proto-public buf module so that we can override the Go package imports within proto/buf.yaml
Bumps the buf version dependency to 1.14.0 (I was trying out the version to see if it would get around an issue - it didn't but it also doesn't break things and it seemed best to keep up with the toolchain changes)
Why:
In the future we will need to consume other protobuf dependencies such as the Google HTTP annotations for openapi generation or grpc-gateway usage.
There were some recent changes to have our own ratelimiting annotations.
The two combined were not working when I was trying to use them together (attempting to rebase another branch)
Buf workspaces should be the solution to the problem
Buf workspaces means that each module will have generated Go code that embeds proto file names relative to the proto dir and not the top level repo root.
This resulted in proto file name conflicts in the Go global protobuf type registry.
The solution to that was to add in a private/ directory into the path within the proto/ directory.
That then required rewriting all the imports.
Is this safe?
AFAICT yes
The gRPC wire protocol doesn't seem to care about the proto file names (although the Go grpc code does tack on the proto file name as Metadata in the ServiceDesc)
Other than imports, there were no changes to any generated code as a result of this.

Fix mesh gateways incorrectly matching peer locality.
This fixes an issue where local mesh gateways use an
incorrect address when attempting to forward traffic to a
peered datacenter. Prior to this change it would use the
lan address instead of the wan if the locality matched. This
should never be done for peering, since we must route all
traffic through the remote mesh gateway.

Prior to this PR, servers / agents would panic and crash if an ingress
or api gateway were configured to use a discovery chain that both:
1. Referenced a peered service
2. Had a mesh gateway mode of local
This could occur, because code for handling upstream watches was shared
between both connect-proxy and the gateways. As a short-term fix, this
PR ensures that the maps are always initialized for these gateway services.
This PR also wraps the proxycfg execution and service
registration calls with recover statements to ensure that future issues
like this do not put the server into an unrecoverable state.

Prior to this commit, secondary datacenters could not be initialized
as peering acceptors if ACLs were enabled. This is due to the fact that
internal server-to-server API calls would fail because the management
token was not generated. This PR makes it so that both primary and
secondary datacenters generate their own management token whenever
a leader is elected in their respective clusters.

Use only the agent token for deregistration during anti-entropy
The previous behavior had the agent attempt to use the "service" token
(i.e. from the `token` field in a service definition file), and if that
was not set then it would use the agent token.
The previous behavior was problematic because, if the service token had
been deleted, the deregistration request would fail. The agent would
retry the deregistration during each anti-entropy sync, and the
situation would never resolve.
The new behavior is to only/always use the agent token for service and
check deregistration during anti-entropy. This approach is:
* Simpler: No fallback logic to try different tokens
* Faster (slightly): No time spent attempting the service token
* Correct: The agent token is able to deregister services on that
agent's node, because:
* node:write permissions allow deregistration of services/checks on
that node.
* The agent token must have node:write permission, or else the agent
is not be able to (de)register itself into the catalog

* Add Tproxy support to Envoy Extensions (this is needed for service to service validation)
* Add validation for Envoy configuration for an upstream service
* Use both /config_dump and /cluster to validate Envoy configuration
This is because of a bug in Envoy where the EndpointsConfigDump does not
include a cluster_name, making it impossible to match an endpoint to
verify it exists.
This removes endpoints support for builtin extensions since only the
validate plugin was using it, and it is no longer used. It also removes
test cases for endpoint validation. Endpoints validation now only occurs
in the top level test from config_dump and clusters json files.

Fix configuration merging for implicit tproxy upstreams.
Change the merging logic so that the wildcard upstream has correct proxy-defaults
and service-defaults values combined into it. It did not previously merge all fields,
and the wildcard upstream did not exist unless service-defaults existed (it ignored
proxy-defaults, essentially).
Change the way we fetch upstream configuration in the xDS layer so that it falls back
to the wildcard when no matching upstream is found. This is what allows implicit peer
upstreams to have the correct "merged" config.
Change proxycfg to always watch local mesh gateway endpoints whenever a peer upstream
is found. This simplifies the logic so that we do not have to inspect the "merged"
configuration on peer upstreams to extract the mesh gateway mode.
Previously, we'd begin a session with the xDS concurrency limiter
regardless of whether the proxy was registered in the catalog or in
the server's local agent state.
This caused problems for users who run `consul connect envoy` directly
against a server rather than a client agent, as the server's locally
registered proxies wouldn't be included in the limiter's capacity.
Now, the `ConfigSource` is responsible for beginning the session and we
only do so for services in the catalog.
Fixes: https://github.com/hashicorp/consul/issues/15753
Enforce lowercase peer names.
Prior to this change peer names could be mixed case.
This can cause issues, as peer names are used as DNS labels
in various locations. It also caused issues with envoy
configuration.
* Protobuf Modernization
Remove direct usage of golang/protobuf in favor of google.golang.org/protobuf
Marshallers (protobuf and json) needed some changes to account for different APIs.
Moved to using the google.golang.org/protobuf/types/known/* for the well known types including replacing some custom Struct manipulation with whats available in the structpb well known type package.
This also updates our devtools script to install protoc-gen-go from the right location so that files it generates conform to the correct interfaces.

Fixes a bug introduced by #15346 where we'd always require an ACL
token even if ACLs were disabled because we were erroneously
treating `nil` identity as anonymous.
This is the OSS portion of enterprise PR 3822.
Adds a custom gRPC balancer that replicates the router's server cycling
behavior. Also enables automatic retries for RESOURCE_EXHAUSTED errors,
which we now get for free.
Adds automation for generating the map of `gRPC Method Name → Rate Limit Type`
used by the middleware introduced in #15550, and will ensure we don't forget
to add new endpoints.
Engineers must annotate their RPCs in the proto file like so:
```
rpc Foo(FooRequest) returns (FooResponse) {
option (consul.internal.ratelimit.spec) = {
operation_type: READ,
};
}
```
When they run `make proto` a protoc plugin `protoc-gen-consul-rate-limit` will
be installed that writes rate-limit specs as a JSON array to a file called
`.ratelimit.tmp` (one per protobuf package/directory).
After running Buf, `make proto` will execute a post-process script that will
ingest all of the `.ratelimit.tmp` files and generate a Go file containing the
mappings in the `agent/grpc-middleware` package. In the enterprise repository,
it will write an additional file with the enterprise-only endpoints.
If an engineer forgets to add the annotation to a new RPC, the plugin will
return an error like so:
```
RPC Foo is missing rate-limit specification, fix it with:
import "proto-public/annotations/ratelimit/ratelimit.proto";
service Bar {
rpc Foo(...) returns (...) {
option (hashicorp.consul.internal.ratelimit.spec) = {
operation_type: OPERATION_READ | OPERATION_WRITE | OPERATION_EXEMPT,
};
}
}
```
In the future, this annotation can be extended to support rate-limit
category (e.g. KV vs Catalog) and to determine the retry policy.
Previously, these endpoints required `service:write` permission on _any_
service as a sort of proxy for "is the caller allowed to participate in
the mesh?".
Now, they're called as part of the process of establishing a server
connection by any consumer of the consul-server-connection-manager
library, which will include non-mesh workloads (e.g. Consul KV as a
storage backend for Vault) as well as ancillary components such as
consul-k8s' acl-init process, which likely won't have `service:write`
permission.
So this commit relaxes those requirements to accept *any* valid ACL token
on the following gRPC endpoints:
- `hashicorp.consul.dataplane.DataplaneService/GetSupportedDataplaneFeatures`
- `hashicorp.consul.serverdiscovery.ServerDiscoveryService/WatchServers`
- `hashicorp.consul.connectca.ConnectCAService/WatchRoots`
Fix agent cache incorrectly notifying unchanged protobufs.
This change fixes a situation where the protobuf private fields
would be read by reflect.DeepEqual() and indicate data was modified.
This resulted in change notifications being fired every time, which
could cause performance problems in proxycfg.
This gets the extensions information for the local service into the snapshot and ExtensionConfigurations for a proxy. It grabs the extensions from config entries and puts them in structs.NodeService.Proxy field, which already is copied into the config snapshot.
Also:
* add EnvoyExtensions to api.AgentService so that it matches structs.NodeService
* extensions: refactor PluginConfiguration into a more generic type
ExtensionConfiguration
Also:
* adds endpoints configuration to lambda golden tests
* uses string constant for builtin/aws/lambda

* add functions for returning the max and min Envoy major versions
- added an UnsupportedEnvoyVersions list
- removed an unused error from TestDetermineSupportedProxyFeaturesFromString
- modified minSupportedVersion to use the function for getting the Min Envoy major version. Using just the major version without the patch is equivalent to using `.0`
* added a function for executing the envoy --version command
- added a new exec.go file to not be locked to unix system
* added envoy version check when using consul connect envoy
* added changelog entry
* added docs change
The new balancer is a patched version of gRPC's default pick_first balancer
which removes the behavior of preserving the active subconnection if
a list of new addresses contains the currently active address.
