Enforce lowercase peer names. (#15697)
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 (#15949)
* 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.

* Fix go-mod-tidy make target to work on all modules

grpc: switch servers and retry on error (#15892)
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.

grpc: add rate-limiting middleware (#15550)
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

freddygv e69bc727ec Update peering establishment to maybe use gateways
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.

freddygv 3034df6a5c Require Connect and TLS to generate peering tokens
By requiring Connect and a gRPC TLS listener we can automatically
configure TLS for all peering control-plane traffic.
2022-10-07 09:06:29 -06:00
freddygv fac3ddc857 Use internal server certificate for peering TLS
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.

xDS Load Balancing (#14397)
Prior to #13244, connect proxies and gateways could only be configured by an
xDS session served by the local client agent.

In an upcoming release, it will be possible to deploy a Consul service mesh
without client agents. In this model, xDS sessions will be handled by the
servers themselves, which necessitates load-balancing to prevent a single
server from receiving a disproportionate amount of load and becoming
overwhelmed.

This introduces a simple form of load-balancing where Consul will attempt to
achieve an even spread of load (xDS sessions) between all healthy servers.
It does so by implementing a concurrent session limiter (limiter.SessionLimiter)
and adjusting the limit according to autopilot state and proxy service
registrations in the catalog.

If a server is already over capacity (i.e. the session limit is lowered),
Consul will begin draining sessions to rebalance the load. This will result
in the client receiving a `RESOURCE_EXHAUSTED` status code. It is the client's
responsibility to observe this response and reconnect to a different server.

Users of the gRPC client connection brokered by the
consul-server-connection-manager library will get this for free.

The rate at which Consul will drain sessions to rebalance load is scaled
dynamically based on the number of proxies in the catalog.

freddygv 650e48624d Allow terminated peerings to be deleted
Peerings are terminated when a peer decides to delete the peering from
their end. Deleting a peering sends a termination message to the peer
and triggers them to mark the peering as terminated but does NOT delete
the peering itself. This is to prevent peerings from disappearing from
both sides just because one side deleted them.

Previously the Delete endpoint was skipping the deletion if the peering
was not marked as active. However, terminated peerings are also
inactive.

This PR makes some updates so that peerings marked as terminated can be
deleted by users.

Replace ring buffer with async version (#14314)
We need to watch for changes to peerings and update the server addresses which get served by the ring buffer.

Also, if there is an active connection for a peer, we are getting up-to-date server addresses from the replication stream and can safely ignore the token's addresses which may be stale.

freddygv c04515a844 Use proto message for each secrets write op
Previously there was a field indicating the operation that triggered a
secrets write. Now there is a message for each operation and it contains
the secret ID being persisted.
2022-08-08 01:41:00 -06:00
freddygv 60d6e28c97 Pass explicit signal with op for secrets write
Previously the updates to the peering secrets UUID table relied on
inferring what action triggered the update based on a reconciliation
against the existing secrets.

Instead we now explicitly require the operation to be given so that the
inference isn't necessary. This makes the UUID table logic easier to
reason about and fixes some related bugs.

There is also an update so that the peering secrets get handled on
snapshots/restores.
2022-08-03 17:25:12 -05:00
freddygv 9ca687bc7c Avoid deleting peering secret UUIDs at dialers
Dialers do not keep track of peering secret UUIDs, so they should not
attempt to clean up data from that table when their peering is deleted.

We also now keep peer server addresses when marking peerings for
deletion. Peer server addresses are used by the ShouldDial() helper
when determining whether the peering is for a dialer or an acceptor.
We need to keep this data so that peering secrets can be cleaned up
accordingly.
