* feat(ingress-gateway): support outlier detection of upstream service for ingress gateway
* changelog
Co-authored-by: Eric Haberkorn <erichaberkorn@gmail.com>
There are a few changes that needed to be made to to handle authorizing
reads for imported data:
- If the data was imported from a peer we should not attempt to read the
data using the traditional authz rules. This is because the name of
services/nodes in a peer cluster are not equivalent to those of the
importing cluster.
- If the data was imported from a peer we need to check whether the
token corresponds to a service, meaning that it has service:write
permissions, or to a local read only token that can read all
nodes/services in a namespace.
This required changes at the policyAuthorizer level, since that is the
only view available to OSS Consul, and at the enterprise
partition/namespace level.
* Fix mesh gateway proxy-defaults not affecting upstreams.
* Clarify distinction with upstream settings
Top-level mesh gateway mode in proxy-defaults and service-defaults gets
merged into NodeService.Proxy.MeshGateway, and only gets merged with
the mode attached to an an upstream in proxycfg/xds.
* Fix mgw mode usage for peered upstreams
There were a couple issues with how mgw mode was being handled for
peered upstreams.
For starters, mesh gateway mode from proxy-defaults
and the top-level of service-defaults gets stored in
NodeService.Proxy.MeshGateway, but the upstream watch for peered data
was only considering the mesh gateway config attached in
NodeService.Proxy.Upstreams[i]. This means that applying a mesh gateway
mode via global proxy-defaults or service-defaults on the downstream
would not have an effect.
Separately, transparent proxy watches for peered upstreams didn't
consider mesh gateway mode at all.
This commit addresses the first issue by ensuring that we overlay the
upstream config for peered upstreams as we do for non-peered. The second
issue is addressed by re-using setupWatchesForPeeredUpstream when
handling transparent proxy updates.
Note that for transparent proxies we do not yet support mesh gateway
mode per upstream, so the NodeService.Proxy.MeshGateway mode is used.
* Fix upstream mesh gateway mode handling in xds
This commit ensures that when determining the mesh gateway mode for
peered upstreams we consider the NodeService.Proxy.MeshGateway config as
a baseline.
In absense of this change, setting a mesh gateway mode via
proxy-defaults or the top-level of service-defaults will not have an
effect for peered upstreams.
* Merge service/proxy defaults in cfg resolver
Previously the mesh gateway mode for connect proxies would be
merged at three points:
1. On servers, in ComputeResolvedServiceConfig.
2. On clients, in MergeServiceConfig.
3. On clients, in proxycfg/xds.
The first merge returns a ServiceConfigResponse where there is a
top-level MeshGateway config from proxy/service-defaults, along with
per-upstream config.
The second merge combines per-upstream config specified at the service
instance with per-upstream config specified centrally.
The third merge combines the NodeService.Proxy.MeshGateway
config containing proxy/service-defaults data with the per-upstream
mode. This third merge is easy to miss, which led to peered upstreams
not considering the mesh gateway mode from proxy-defaults.
This commit removes the third merge, and ensures that all mesh gateway
config is available at the upstream. This way proxycfg/xds do not need
to do additional overlays.
* Ensure that proxy-defaults is considered in wc
Upstream defaults become a synthetic Upstream definition under a
wildcard key "*". Now that proxycfg/xds expect Upstream definitions to
have the final MeshGateway values, this commit ensures that values from
proxy-defaults/service-defaults are the default for this synthetic
upstream.
* Add changelog.

Re-add ServerExternalAddresses parameter in GenerateToken endpoint
This reverts commit 5e156772f6
and adds extra functionality to support newer peering behaviors.
Fix an issue where rpc_hold_timeout was being used as the timeout for non-blocking queries. Users should be able to tune read timeouts without fiddling with rpc_hold_timeout. A new configuration `rpc_read_timeout` is created.
Refactor some implementation from the original PR 11500 to remove the misleading linkage between RPCInfo's timeout (used to retry in case of certain modes of failures) and the client RPC timeouts.
Replaces the reflection-based implementation of proxycfg's
ConfigSnapshot.Clone with code generated by deep-copy.
While load testing server-based xDS (for consul-dataplane) we discovered
this method is extremely expensive. The ConfigSnapshot struct, directly
or indirectly, contains a copy of many of the structs in the agent/structs
package, which creates a large graph for copystructure.Copy to traverse
at runtime, on every proxy reconfiguration.
This commit adds the xDS resources needed for INBOUND traffic from peer
clusters:
- 1 filter chain for all inbound peering requests.
- 1 cluster for all inbound peering requests.
- 1 endpoint per voting server with the gRPC TLS port configured.
There is one filter chain and cluster because unlike with WAN
federation, peer clusters will not attempt to dial individual servers.
Peer clusters will only dial the local mesh gateway addresses.
* feat(ingress gateway: support configuring limits in ingress-gateway config entry
- a new Defaults field with max_connections, max_pending_connections, max_requests
is added to ingress gateway config entry
- new field max_connections, max_pending_connections, max_requests in
individual services to overwrite the value in Default
- added unit test and integration test
- updated doc

This commit introduces a new ACL token used for internal server
management purposes.
It has a few key properties:
- It has unlimited permissions.
- It is persisted through Raft as System Metadata rather than in the
ACL tokens table. This is to avoid users seeing or modifying it.
- It is re-generated on leadership establishment.

By adding a SpiffeID for server agents, servers can now request a leaf
certificate from the Connect CA.
This new Spiffe ID has a key property: servers are identified by their
datacenter name and trust domain. All servers that share these
attributes will share a ServerURI.
The aim is to use these certificates to verify the server name of ANY
server in a Consul datacenter.

Consul 1.13.0 changed ServiceVirtualIP to use PeeredServiceName instead of ServiceName which was a breaking change for those using service mesh and wanted to restore their snapshot after upgrading to 1.13.0.
This commit handles existing data with older ServiceName and converts it during restore so that there are no issues when restoring from older snapshots.
This commit adds a new ACL rule named "peering" to authorize
actions taken against peering-related endpoints.
The "peering" rule has several key properties:
- It is scoped to a partition, and MUST be defined in the default
namespace.
- Its access level must be "read', "write", or "deny".
- Granting an access level will apply to all peerings. This ACL rule
cannot be used to selective grant access to some peerings but not
others.
- If the peering rule is not specified, we fall back to the "operator"
rule and then the default ACL rule.
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.
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 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
Having this type live in the agent/consul package makes it difficult to
put anything that relies on token resolution (e.g. the new gRPC services)
in separate packages without introducing import cycles.
For example, if package foo imports agent/consul for the ACLResolveResult
type it means that agent/consul cannot import foo to register its service.
We've previously worked around this by wrapping the ACLResolver to
"downgrade" its return type to an acl.Authorizer - aside from the
added complexity, this also loses the resolved identity information.
In the future, we may want to move the whole ACLResolver into the
acl/resolver package. For now, putting the result type there at least,
fixes the immediate import cycle issues.
This is only configured in xDS when a service with an L7 protocol is
exported.
They also load any relevant trust bundles for the peered services to
eventually use for L7 SPIFFE validation during mTLS termination.
Adds the merge-central-config query param option to the /catalog/node-services/:node-name API,
to get a service definition in the response that is merged with central defaults (proxy-defaults/service-defaults).
Updated the consul connect envoy command to use this option when
retrieving the proxy service details so as to render the bootstrap configuration correctly.

Mesh gateways will now enable tcp connections with SNI names including peering information so that those connections may be proxied.
Note: this does not change the callers to use these mesh gateways.
Given that the exported-services config entry can use wildcards, the
precedence for wildcards is handled as with intentions. The most exact
match is the match that applies for any given service. We do not take
the union of all that apply.
Another update that was made was to reflect that only one
exported-services config entry applies to any given service in a
partition. This is a pre-existing constraint that gets enforced by
the Normalize() method on that config entry type.

OSS port of enterprise PR 1822
Includes the necessary changes to the `proxycfg` and `xds` packages to enable
Consul servers to configure arbitrary proxies using catalog data.
Broadly, `proxycfg.Manager` now has public methods for registering,
deregistering, and listing registered proxies — the existing local agent
state-sync behavior has been moved into a separate component that makes use of
these methods.
When an xDS session is started for a proxy service in the catalog, a goroutine
will be spawned to watch the service in the server's state store and
re-register it with the `proxycfg.Manager` whenever it is updated (and clean
it up when the client goes away).
Adds a new query param merge-central-config for use with the below endpoints:
/catalog/service/:service
/catalog/connect/:service
/health/service/:service
/health/connect/:service
If set on the request, the response will include a fully resolved service definition which is merged with the proxy-defaults/global and service-defaults/:service config entries (on-demand style). This is useful to view the full service definition for a mesh service (connect-proxy kind or gateway kind) which might not be merged before being written into the catalog (example: in case of services in the agentless model).
The importing peer will need to know what SNI and SPIFFE name
corresponds to each exported service. Additionally it will need to know
at a high level the protocol in use (L4/L7) to generate the appropriate
connection pool and local metrics.
For replicated connect synthetic entities we edit the `Connect{}` part
of a `NodeService` to have a new section:
{
"PeerMeta": {
"SNI": [
"web.default.default.owt.external.183150d5-1033-3672-c426-c29205a576b8.consul"
],
"SpiffeID": [
"spiffe://183150d5-1033-3672-c426-c29205a576b8.consul/ns/default/dc/dc1/svc/web"
],
"Protocol": "tcp"
}
}
This data is then replicated and saved as-is at the importing side. Both
SNI and SpiffeID are slices for now until I can be sure we don't need
them for how mesh gateways will ultimately work.
Treat each exported service as a "discovery chain" and replicate one
synthetic CheckServiceNode for each chain and remote mesh gateway.
The health will be a flattened generated check of the checks for that
mesh gateway node.
Add validation to ensure connect native services have a port or socketpath specified on catalog registration.
This was the only missing piece to ensure all mesh services are validated for a port (or socketpath) specification on catalog registration.
* Support vault namespaces in connect CA
Follow on to some missed items from #12655
From an internal ticket "Support standard "Vault namespace in the
path" semantics for Connect Vault CA Provider"
Vault allows the namespace to be specified as a prefix in the path of
a PKI definition, but our usage of the Vault API includes calls that
don't support a namespaced key. In particular the sys.* family of
calls simply appends the key, instead of prefixing the namespace in
front of the path.
Unfortunately it is difficult to reliably parse a path with a
namespace; only vault knows what namespaces are present, and the '/'
separator can be inside a key name, as well as separating path
elements. This is in use in the wild; for example
'dc1/intermediate-key' is a relatively common naming schema.
Instead we add two new fields: RootPKINamespace and
IntermediatePKINamespace, which are the absolute namespace paths
'prefixed' in front of the respective PKI Paths.

Description
Add x-fowarded-client-cert information on trusted incoming connections.
Envoy provides support forwarding and annotating the
x-forwarded-client-cert header via the forward_client_cert_details
set_current_client_cert_details filter fields. It would be helpful for
consul to support this directly in its config. The escape hatches are
a bit cumbersome for this purpose.
This has been implemented on incoming connections to envoy. Outgoing
(from the local service through the sidecar) will not have a
certificate, and so are left alone.
A service on an incoming connection will now get headers something like this:
```

Closes#12852
The primary bug here is in the streaming subsystem that makes the overall v1/health/service/:service request behave incorrectly when servicing a blocking request with a filter provided.
There is a secondary non-streaming bug being fixed here that is much less obvious related to when to update the `reply` variable in a `blockingQuery` evaluation. It is unlikely that it is triggerable in practical environments and I could not actually get the bug to manifest, but I fixed it anyway while investigating the original issue.
Simple reproduction (streaming):
1. Register a service with a tag.
curl -sL --request PUT 'http://localhost:8500/v1/agent/service/register' \
--header 'Content-Type: application/json' \
--data-raw '{ "ID": "ID1", "Name": "test", "Tags":[ "a" ], "EnableTagOverride": true }'
2. Do an initial filter query that matches on the tag.
curl -sLi --get 'http://localhost:8500/v1/health/service/test' --data-urlencode 'filter=a in Service.Tags'
3. Note you get one result. Use the `X-Consul-Index` header to establish
a blocking query in another terminal, this should not return yet.
curl -sLi --get 'http://localhost:8500/v1/health/service/test?index=$INDEX' --data-urlencode 'filter=a in Service.Tags'
4. Re-register that service with a different tag.
curl -sL --request PUT 'http://localhost:8500/v1/agent/service/register' \
--header 'Content-Type: application/json' \
--data-raw '{ "ID": "ID1", "Name": "test", "Tags":[ "b" ], "EnableTagOverride": true }'
5. Your blocking query from (3) should return with a header
`X-Consul-Query-Backend: streaming` and empty results if it works
correctly `[]`.
Attempts to reproduce with non-streaming failed (where you add `&near=_agent` to the read queries and ensure `X-Consul-Query-Backend: blocking-query` shows up in the results).
Adds a timeout (deadline) to client RPC calls, so that streams will no longer hang indefinitely in unstable network conditions.

Just like standard upstreams the order of applicability in descending precedence:
1. caller's `service-defaults` upstream override for destination
2. caller's `service-defaults` upstream defaults
3. destination's `service-resolver` ConnectTimeout
4. system default of 5s

This extends the acl.AllowAuthorizer with source of authority information.
The next step is to unify the AllowAuthorizer and ACLResolveResult structures; that will be done in a separate PR.

Currently the config_entry.go subsystem delegates authorization decisions via the ConfigEntry interface CanRead and CanWrite code. Unfortunately this returns a true/false value and loses the details of the source.
This is not helpful, especially since it the config subsystem can be more complex to understand, since it covers so many domains.
This refactors CanRead/CanWrite to return a structured error message (PermissionDenied or the like) with more details about the reason for denial.

Many places in consul already treated node names case insensitively.
The state store indexes already do it, but there are a few places that
did a direct byte comparison which have now been corrected.
One place of particular consideration is ensureCheckIfNodeMatches
which is executed during snapshot restore (among other places). If a
node check used a slightly different casing than the casing of the node
during register then the snapshot restore here would deterministically
fail. This has been fixed.
Primary approach:
git grep -i "node.*[!=]=.*node" -- ':!*_test.go' ':!docs'
git grep -i '\[[^]]*member[^]]*\]
git grep -i '\[[^]]*\(member\|name\|node\)[^]]*\]' -- ':!*_test.go' ':!website' ':!ui' ':!agent/proxycfg/testing.go:' ':!*.md'

Due to timing, a transparent proxy could have two upstreams to dial
directly with the same address.
For example:
- The orders service can dial upstreams shipping and payment directly.
- An instance of shipping at address 10.0.0.1 is deregistered.
- Payments is scaled up and scheduled to have address 10.0.0.1.
- The orders service receives the event for the new payments instance
before seeing the deregistration for the shipping instance. At this
point two upstreams have the same passthrough address and Envoy will
reject the listener configuration.
To disambiguate this commit considers the Raft index when storing
passthrough addresses. In the example above, 10.0.0.1 would only be
associated with the newer payments service instance.

The gist here is that now we use a value-type struct proxycfg.UpstreamID
as the map key in ConfigSnapshot maps where we used to use "upstream
id-ish" strings. These are internal only and used just for bidirectional
trips through the agent cache keyspace (like the discovery chain target
struct).
For the few places where the upstream id needs to be projected into xDS,
that's what (proxycfg.UpstreamID).EnvoyID() is for. This lets us ALWAYS
inject the partition and namespace into these things without making
stuff like the golden testdata diverge.
This safeguard should be safe to apply in general. We are already
applying it to non-blocking queries that call blockingQuery, so it
should be fine to apply it to others.

Use the new verifyLearfCert to show the cert verifies with intermediates
from both sources. This required using the RPC interface so that the
leaf pem was constructed correctly.
Add IndexedCARoots.Active since that is a common operation we see in a
few places.
Failing over to a partition is more siimilar to failing over to another
datacenter than it is to failing over to a namespace. In a future
release we should update how localities for failover are specified. We
should be able to accept a list of localities which can include both
partition and datacenter.
* Add partition fields to targets like service route destinations
* Update validation to prevent cross-DC + cross-partition references
* Handle partitions when reading config entries for disco chain
* Encode partition in compiled targets
This table purposefully does not index by partition/namespace. It's a
global view into all service names.
This table is intended to replace the current serviceListTxn watch in
intentionTopologyTxn. For cross-partition transparent proxying we need
to be able to calculate upstreams from intentions in any partition. This
means that the existing serviceListTxn function is insufficient since
it's scoped to a partition.
Moving away from that function is also beneficial because it watches the
main "services" table, so watchers will wake up when any instance is
registered or deregistered.

As a method on the struct type this would not be safe to call without first checking
c.isIntermediateUsedToSignLeaf.
So for now, move this logic to the CAMananger, so that it is always correct.
We were not adding the local signing cert to the CARoot. This commit
fixes that bug, and also adds support for fixing existing CARoot on
upgrade.
Also update the tests for both primary and secondary to be more strict.
Check the SigningKeyID is correct after initialization and rotation.
Validation was added on the config entry kind since that is called when
validating config entries to bootstrap via agent configuration and when
applying entries via the config RPC endpoint.

* Support vault auth methods for the Vault connect CA provider
* Rotate the token (re-authenticate to vault using auth method) when the token can no longer be renewed
Fixes an issue described in #10132, where if two DCs are WAN federated
over mesh gateways, and the gateway in the non-primary DC is terminated
and receives a new IP address (as is commonly the case when running them
on ephemeral compute instances) the primary DC is unable to re-establish
its connection until the agent running on its own gateway is restarted.
This was happening because we always preferred gateways discovered by
the `Internal.ServiceDump` RPC (which would fail because there's no way
to dial the remote DC) over those discovered in the federation state,
which is replicated as long as the primary DC's gateway is reachable.

ACLResolver cache, but the acl.Policy ID and revision are not used.
* Support Vault Namespaces explicitly in CA config
If there is a Namespace entry included in the Vault CA configuration,
set it as the Vault Namespace on the Vault client
Currently the only way to support Vault namespaces in the Consul CA
config is by doing one of the following:
1) Set the VAULT_NAMESPACE environment variable which will be picked up
by the Vault API client
2) Prefix all Vault paths with the namespace
Neither of these are super pleasant. The first requires direct access
and modification to the Consul runtime environment. It's possible and
expected, not super pleasant.
The second requires more indepth knowledge of Vault and how it uses
Namespaces and could be confusing for anyone without that context. It
also infers that it is not supported

The api module has decoding functions that rely on 'kind' being present
of payloads. This is so that we can decode into the appropriate api type
for the config entry.
This commit ensures that a static kind is marshalled in responses from
Consul's api endpoints so that the api module can decode them.
Existing config entries prefixed by service- are specific to individual
services. Since this config entry applies to partitions it is being
renamed.
Additionally, the Partition label was changed to Name because using
Partition at the top-level and in the enterprise meta was leading to the
enterprise meta partition being dropped by msgpack.
