Fix configuration merging for implicit tproxy upstreams. (#16000)
Fix configuration merging for implicit tproxy upstreams.

Change the merging logic so that the wildcard upstream has correct proxy-defaults
and service-defaults values combined into it. It did not previously merge all fields,
and the wildcard upstream did not exist unless service-defaults existed (it ignored
proxy-defaults, essentially).

Change the way we fetch upstream configuration in the xDS layer so that it falls back
to the wildcard when no matching upstream is found. This is what allows implicit peer
upstreams to have the correct "merged" config.

Change proxycfg to always watch local mesh gateway endpoints whenever a peer upstream
is found. This simplifies the logic so that we do not have to inspect the "merged"
configuration on peer upstreams to extract the mesh gateway mode.

Fix issue with incorrect proxycfg watch on upstream peer-targets. (#15865)
This fixes an issue where the incorrect partition was given to the
upstream target watch, which meant that failover logic would not
work correctly.

Fix local mesh gateway with peering discovery chains. (#15690)
Fix local mesh gateway with peering discovery chains.

Prior to this patch, discovery chains with peers would not
properly honor the mesh gateway mode for two reasons.

1. An incorrect target upstream ID was used to lookup the
mesh gateway mode. To fix this, the parent upstream uid is
now used instead of the discovery-chain-target-uid to find
the intended mesh gateway mode.

2. The watch for local mesh gateways was never initialized
for discovery chains. To fix this, the discovery chains are
now scanned, and a local GW watch is spawned if: the mesh
gateway mode is local and the target is a peering connection.

Fix mesh gateway configuration with proxy-defaults (#15186)
* 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.

proxycfg: rate-limit delivery of config snapshots (#14960)
Adds a user-configurable rate limiter to proxycfg snapshot delivery,
with a default limit of 250 updates per second.

This addresses a problem observed in our load testing of Consul
Dataplane where updating a "global" resource such as a wildcard
intention or the proxy-defaults config entry could starve the Raft or
Memberlist goroutines of CPU time, causing general cluster instability.

perf: remove expensive reflection from xDS hot path (#14934)
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.

Service http checks data source for agentless proxies (#14924)
Adds another datasource for proxycfg.HTTPChecks, for use on server agents. Typically these checks are performed by local client agents and there is no equivalent of this in agentless (where servers configure consul-dataplane proxies).
Hence, the data source is mostly a no-op on servers but in the case where the service is present within the local state, it delegates to the cache data source.

freddygv b15d41534f Update xds generation for peering over mesh gws
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.

freddygv d818d7b096 Manage local server watches depending on mesh cfg
Routing peering control plane traffic through mesh gateways can be
enabled or disabled at runtime with the mesh config entry.

This commit updates proxycfg to add or cancel watches for local servers
depending on this central config.

Note that WAN federation over mesh gateways is determined by a service
metadata flag, and any updates to the gateway service registration will
force the creation of a new snapshot. If enabled, WAN-fed over mesh
gateways will trigger a local server watch on initialize().

Because of this we will only add/remove server watches if WAN federation
over mesh gateways is disabled.

Daniel Upton 13c04a13af proxycfg: terminate stream on irrecoverable errors
This is the OSS portion of enterprise PR 2339.

It improves our handling of "irrecoverable" errors in proxycfg data sources.

The canonical example of this is what happens when the ACL token presented by
Envoy is deleted/revoked. Previously, the stream would get "stuck" until the
xDS server re-checked the token (after 5 minutes) and terminated the stream.

Materializers would also sit burning resources retrying something that could
never succeed.

Now, it is possible for data sources to mark errors as "terminal" which causes
the xDS stream to be closed immediately. Similarly, the submatview.Store will
evict materializers when it observes they have encountered such an error.

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.

Daniel Upton 37ccbd2826 proxycfg: server-local intentions data source
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.

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.

xds: allow for peered upstreams to use tagged addresses that are hostnames (#13422)
Mesh gateways can use hostnames in their tagged addresses (#7999). This is useful
if you were to expose a mesh gateway using a cloud networking load balancer appliance
that gives you a DNS name but no reliable static IPs.

Envoy cannot accept hostnames via EDS and those must be configured using CDS.
There was already logic when configuring gateways in other locations in the code, but
given the illusions in play for peering the downstream of a peered service wasn't aware
that it should be doing that.

Also:
- ensuring that we always try to use wan-like addresses to cross peer boundaries.

Freddy a09c776645 Update public listener with SPIFFE Validator
Envoy's SPIFFE certificate validation extension allows for us to
validate against different root certificates depending on the trust
domain of the dialing proxy.

If there are any trust bundles from peers in the config snapshot then we
use the SPIFFE validator as the validation context, rather than the
usual TrustedCA.

The injected validation config includes the local root certificates as
well.

Configure upstream TLS context with peer root certs (#13321)
For mTLS to work between two proxies in peered clusters with different root CAs,
proxies need to configure their outbound listener to use different root certificates
for validation.

Up until peering was introduced proxies would only ever use one set of root certificates
to validate all mesh traffic, both inbound and outbound. Now an upstream proxy
may have a leaf certificate signed by a CA that's different from the dialing proxy's.

This PR makes changes to proxycfg and xds so that the upstream TLS validation
uses different root certificates depending on which cluster is being dialed.

proxycfg: replace direct agent cache usage with interfaces (#13320)
This is the OSS portion of enterprise PRs 1904, 1905, 1906, 1907, 1949,

It replaces the proxycfg manager's direct dependency on the agent cache
with interfaces that will be implemented differently when serving xDS

Enable servers to configure arbitrary proxies from the catalog (#13244)
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).

proxycfg: remove dependency on `cache.UpdateEvent` (#13144)
OSS portion of enterprise PR 1857.

This removes (most) references to the `cache.UpdateEvent` type in the
`proxycfg` package.

As we're going to be direct usage of the agent cache with interfaces that
can be satisfied by alternative server-local datasources, it doesn't make
sense to depend on this type everywhere anymore (particularly on the
`state.ch` channel).

We also plan to extract `proxycfg` out of Consul into a shared library in
the future, which would require removing this dependency.

Aside from a fairly rote find-and-replace, the main change is that the
`cache.Cache` and `health.Client` types now accept a callback function
parameter, rather than a `chan<- cache.UpdateEvents`. This allows us to
do the type conversion without running another goroutine.

proxycfg: change how various proxycfg test helpers for making ConfigSnapshot copies works to be more correct and less error prone (#12531)
Prior to this PR for the envoy xDS golden tests in the agent/xds package we
were hand-creating a proxycfg.ConfigSnapshot structure in the proper format for
input to the xDS generator. Over time this intermediate structure has gotten
trickier to build correctly for the various tests.

This PR proposes to switch to using the existing mechanism for turning a
structs.NodeService and a sequence of cache.UpdateEvent copies into a
proxycfg.ConfigSnapshot, as that is less error prone to construct and aligns
more with how the data arrives.

NOTE: almost all of this is in test-related code. I tried super hard to craft
correct event inputs to get the golden files to be the same, or similar enough
after construction to feel ok that i recreated the spirit of the original test
cases.

freddygv ceb52d649a Account for upstream targets in another DC.
Transparent proxies typically cannot dial upstreams in remote
datacenters. However, if their upstream configures a redirect to a
remote DC then the upstream targets will be in another datacenter.

In that sort of case we should use the WAN address for the passthrough.
2022-02-10 17:01:57 -07:00
freddygv cbea3d203c Fix race of upstreams with same passthrough ip
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.
2022-02-10 17:01:57 -07:00
freddygv 659ebc05a9 Ensure passthrough addresses get cleaned up
Transparent proxies can set up filter chains that allow direct
connections to upstream service instances. Services that can be dialed
directly are stored in the PassthroughUpstreams map of the proxycfg
snapshot.

Previously these addresses were not being cleaned up based on new
service health data. The list of addresses associated with an upstream
service would only ever grow.

As services scale up and down, eventually they will have instances
assigned to an IP that was previously assigned to a different service.
When IP addresses are duplicated across filter chain match rules the
listener config will be rejected by Envoy.

This commit updates the proxycfg snapshot management so that passthrough
addresses can get cleaned up when no longer associated with a given
upstream.

There is still the possibility of a race condition here where due to
timing an address is shared between multiple passthrough upstreams.
That concern is mitigated by #12195, but will be further addressed
in a follow-up.

proxycfg: introduce explicit UpstreamID in lieu of bare string (#12125)
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.
