xds: modify rbac rules to use the XFCC header for peered L7 enforcement (#13629)
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.

Pass trust domain to RBAC to validate and fix use of wrong peer trust bundles (#13508) 2022-06-20 22:47:14 -04:00

Update RBAC to handle imported services (#13404)
When converting from Consul intentions to xds RBAC rules, services imported from other peers must encode additional data like partition (from the remote cluster) and trust domain.

This PR updates the PeeringTrustBundle to hold the sending side's local partition as ExportedPartition. It also updates RBAC code to encode SpiffeIDs of imported services with the ExportedPartition and TrustDomain.

test: omit envoy golden test files that differ from the latest version (#9807)
Since we currently do no version switching this removes 75% of the PR
noise.

To generate all *.golden files were removed and then I ran:

    go test ./agent/xds -update

xds: remove deprecated usages of xDS (#9602)
Note that this does NOT upgrade to xDS v3. That will come in a future PR.

Additionally:

- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.

Fixes #8425

connect: support defining intentions using layer 7 criteria (#8839)
Extend Consul’s intentions model to allow for request-based access control enforcement for HTTP-like protocols in addition to the existing connection-based enforcement for unspecified protocols (e.g. tcp).

connect: intentions are now managed as a new config entry kind "service-intentions" (#8834)
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.

- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.

- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.

- Add a new serf feature flag indicating support for
intentions-as-config-entries.

- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.

- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.

- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.

- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.
