For L4/tcp exported services the mesh gateways will not be terminating
TLS. A caller in one peer will be directly establishing TLS connections
to the ultimate exported service in the other peer.
The caller will be doing SAN validation using the replicated SpiffeID
values shipped from the exporting side. There are a class of discovery
chain edits that could be done on the exporting side that would cause
the introduction of a new SpiffeID value. In between the time of the
config entry update on the exporting side and the importing side getting
updated peer stream data requests to the exported service would fail due
to SAN validation errors.
This is unacceptable so instead prohibit the exporting peer from making
changes that would break peering in this way.
Because peerings are pairwise, between two tuples of (datacenter,
partition) having any exported reference via a discovery chain that
crosses out of the peered datacenter or partition will ultimately not be
able to work for various reasons. The biggest one is that there is no
way in the ultimate destination to configure an intention that can allow
an external SpiffeID to access a service.
This PR ensures that a user simply cannot do this, so they won't run
into weird situations like this.
* Request peering permissions when peerings is active
* Update peering ability to use peering resource
* fix canDelete peer permission to check write permission
* use super call in abilities.peer#canDelete
* ui: use environment variable for feature flagging peers
* Add documentation for `features`-service
* Allow setting feature flag for peers via bookmarklet
* don't use features service for flagging peers
* add ability for checking if peers feature is enabled
* Use abilities to conditionally use peers feature
* Remove unused features service
* feat(cli): enable to delete config entry from an input file
- A new flag to config delete to delete a config entry in a
valid config file, e.g., config delete -filename
intention-allow.hcl
- Updated flag validation; -filename and -kind can't be set
at the same time
- Move decode config entry method from config_write.go to
helpers.go for reusing ParseConfigEntry()
- add changelog

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.
