Peer replication is intended to be between separate Consul installs and
effectively should be considered "external". This PR moves the peer
stream replication bidirectional RPC endpoint to the external gRPC
server and ensures that things continue to function.
Currently servers exchange information about their WAN serf port
and RPC port with serf tags, so that they all learn of each other's
addressing information. We intend to make larger use of the new
public-facing gRPC port exposed on all of the servers, so this PR
addresses that by passing around the gRPC port via serf tags and
then ensuring the generated consul service in the catalog has
metadata about that new port as well for ease of non-serf-based lookup.
This commit updates the DNS query locality parsing so that the virtual
IP for an imported service can be queried.
Note that:
- Support for parsing a peer in other service discovery queries was not
added.
- Querying another datacenter for a virtual IP is not supported. This
was technically allowed in 1.11 but is being rolled back for 1.13
because it is not a use-case we intended to support. Virtual IPs in
different datacenters are going to collide because they are allocated
sequentially.
These changes are primarily for Consul's UI, where we want to be more
specific about the state a peering is in.
- The "initial" state was renamed to pending, and no longer applies to
peerings being established from a peering token.
- Upon request to establish a peering from a peering token, peerings
will be set as "establishing". This will help distinguish between the
two roles: the cluster that generates the peering token and the
cluster that establishes the peering.
- When marked for deletion, peering state will be set to "deleting".
This way the UI determines the deletion via the state rather than the
"DeletedAt" field.

This is the OSS portion of enterprise PR 2157.
It builds on the local blocking query work in #13438 to implement the
proxycfg.IntentionUpstreams interface using server-local data.
Also moves the ACL filtering logic from agent/consul into the acl/filter
package so that it can be reused here.
This is the OSS portion of enterprise PR 2141.
This commit provides a server-local implementation of the `proxycfg.Intentions`
interface that sources data from streaming events.
It adds events for the `service-intentions` config entry type, and then consumes
event streams (via materialized views) for the service's explicit intentions and
any applicable wildcard intentions, merging them into a single list of intentions.
An alternative approach I considered was to consume _all_ intention events (via
`SubjectWildcard`) and filter out the irrelevant ones. This would admittedly
remove some complexity in the `agent/proxycfg-glue` package but at the expense
of considerable overhead from waking potentially many thousands of connect
proxies every time any intention is updated.
This is the OSS portion of enterprise PR 2056.
This commit provides server-local implementations of the proxycfg.ConfigEntry
and proxycfg.ConfigEntryList interfaces, that source data from streaming events.
It makes use of the LocalMaterializer type introduced for peering replication,
adding the necessary support for authorization.
It also adds support for "wildcard" subscriptions (within a topic) to the event
publisher, as this is needed to fetch service-resolvers for all services when
configuring mesh gateways.
Currently, events will be emitted for just the ingress-gateway, service-resolver,
and mesh config entry types, as these are the only entries required by proxycfg
— the events will be emitted on topics named IngressGateway, ServiceResolver,
and MeshConfig topics respectively.
Though these events will only be consumed "locally" for now, they can also be
consumed via the gRPC endpoint (confirmed using grpcurl) so using them from
client agents should be a case of swapping the LocalMaterializer for an
RPCMaterializer.
For initial cluster peering TProxy support we consider all imported services of a partition to be potential upstreams.
We leverage the VirtualIP table because it stores plain service names (e.g. "api", not "api-sidecar-proxy").
When the protocol is http-like, and an intention has a peered source
then the normal RBAC mTLS SAN field check is replaces with a joint combo
of:
mTLS SAN field must be the service's local mesh gateway leaf cert
AND
the first XFCC header (from the MGW) must have a URI field that matches the original intention source
Also:
- Update the regex program limit to be much higher than the teeny
defaults, since the RBAC regex constructions are more complicated now.
- Fix a few stray panics in xds generation.
When traversing an exported peered service, the discovery chain
evaluation at the other side may re-route the request to a variety of
endpoints. Furthermore we intend to terminate mTLS at the mesh gateway
for arriving peered traffic that is http-like (L7), so the caller needs
to know the mesh gateway's SpiffeID in that case as well.
The following new SpiffeID values will be shipped back in the peerstream
replication:
- tcp: all possible SpiffeIDs resulting from the service-resolver
component of the exported discovery chain
- http-like: the SpiffeID of the mesh gateway
