This implements permissive mTLS , which allows toggling services into "permissive" mTLS mode.
Permissive mTLS mode allows incoming "non Consul-mTLS" traffic to be forward unmodified to the application.
* Update service-defaults and proxy-defaults config entries with a MutualTLSMode field
* Update the mesh config entry with an AllowEnablingPermissiveMutualTLS field and implement the necessary validation. AllowEnablingPermissiveMutualTLS must be true to allow changing to MutualTLSMode=permissive, but this does not require that all proxy-defaults and service-defaults are currently in strict mode.
* Update xDS listener config to add a "permissive filter chain" when MutualTLSMode=permissive for a particular service. The permissive filter chain matches incoming traffic by the destination port. If the destination port matches the service port from the catalog, then no mTLS is required and the traffic sent is forwarded unmodified to the application.
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.
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.
* Refactored "NewGatewayService" to handle namespaces, fixed
TestHTTPRouteFlattening test
* Fixed existing http_route tests for namespacing
* Squash aclEnterpriseMeta for ResourceRefs and HTTPServices, accept
namespace for creating connect services and regular services
* Use require instead of assert after creating namespaces in
http_route_tests
* Refactor NewConnectService and NewGatewayService functions to use cfg
objects to reduce number of method args
* Rename field on SidecarConfig in tests from `SidecarServiceName` to
`Name` to avoid stutter
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.
* Leverage ServiceResolver ConnectTimeout for route timeouts to make TerminatingGateway upstream timeouts configurable
* Regenerate golden files
* Add RequestTimeout field
* Add changelog entry
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.
* Fix infinite recursion on InlineCertificateConfigEntry
GetNamespace() + GetMeta() were calling themselves. This change also simplifies by removing nil-checking to match pre-existing config entries
