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.	2 years ago

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.	2 years ago

Chris S. Kim	8ed49ea4d0	Update envoy metrics label extraction for peered clusters and listeners (#13818) ... Now that peered upstreams can generate envoy resources (#13758), we need a way to disambiguate local from peered resources in our metrics. The key difference is that datacenter and partition will be replaced with peer, since in the context of peered resources partition is ambiguous (could refer to the partition in a remote cluster or one that exists locally). The partition and datacenter of the proxy will always be that of the source service. Regexes were updated to make emitting datacenter and partition labels mutually exclusive with peer labels. Listener filter names were updated to better match the existing regex. Cluster names assigned to peered upstreams were updated to be synthesized from local peer name (it previously used the externally provided primary SNI, which contained the peer name from the other side of the peering). Integration tests were updated to assert for the new peer labels.	2 years ago

R.B. Boyer	31b95c747b	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.	2 years ago

Chris S. Kim	a02e9abcc1	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.

Dan Upton	b168424398	xds: remove HTTPCheckFetcher dependency (#13366) ... This is the OSS portion of enterprise PR 1994 Rather than directly interrogating the agent-local state for HTTP checks using the `HTTPCheckFetcher` interface, we now rely on the config snapshot containing the checks. This reduces the number of changes required to support server xDS sessions. It's not clear why the fetching approach was introduced in 931d167ebb.	3 years ago

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.	3 years ago
Freddy	74ca6406ea	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.	3 years ago

Mark Anderson	28b4b3a85d	Add x-forwarded-client-cert headers ... 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: ``` X-Forwarded-Client-Cert:[By=spiffe://efad7282-d9b2-3298-f6d8-38b37fb58df3.consul/ns/default/dc/dc1/svc/counting;Hash=61ad5cbdfcb50f5a3ec0ca60923d61613c149a9d4495010a64175c05a0268ab2;Cert="-----BEGIN%20CERTIFICATE-----%0AMIICHDCCAcOgAwIBAgIBCDAKBggqhkjOPQQDAjAxMS8wLQYDVQQDEyZwcmktMTli%0AYXdyb2YuY29uc3VsLmNhLmVmYWQ3MjgyLmNvbnN1bDAeFw0yMjA0MjkwMzE0NTBa%0AFw0yMjA1MDIwMzE0NTBaMAAwWTATBgcqhkjOPQIBBggqhkjOPQMBBwNCAARVIZ7Y%0AZEXfbOGBfxGa7Vuok1MIng%2FuzLQK2xLVlSTIPDbO5hstTGP%2B%2FGx182PYFP3jYqk5%0Aq6rYWe1wiPNMA30Io4H8MIH5MA4GA1UdDwEB%2FwQEAwIDuDAdBgNVHSUEFjAUBggr%0ABgEFBQcDAgYIKwYBBQUHAwEwDAYDVR0TAQH%2FBAIwADApBgNVHQ4EIgQgrp4q50oX%0AHHghMbxz5Bk8OJFWMdfgH0Upr350WlhyxvkwKwYDVR0jBCQwIoAgUe6uERAIj%2FLM%0AyuFzDc3Wbp9TGAKBJYAwyhF14ToOQCMwYgYDVR0RAQH%2FBFgwVoZUc3BpZmZlOi8v%0AZWZhZDcyODItZDliMi0zMjk4LWY2ZDgtMzhiMzdmYjU4ZGYzLmNvbnN1bC9ucy9k%0AZWZhdWx0L2RjL2RjMS9zdmMvZGFzaGJvYXJkMAoGCCqGSM49BAMCA0cAMEQCIDwb%0AFlchufggNTijnQ5SUcvTZrWlZyq%2FrdVC20nbbmWLAiAVshNNv1xBqJI1NmY2HI9n%0AgRMfb8aEPVSuxEHhqy57eQ%3D%3D%0A-----END%20CERTIFICATE-----%0A";Chain="-----BEGIN%20CERTIFICATE-----%0AMIICHDCCAcOgAwIBAgIBCDAKBggqhkjOPQQDAjAxMS8wLQYDVQQDEyZwcmktMTli%0AYXdyb2YuY29uc3VsLmNhLmVmYWQ3MjgyLmNvbnN1bDAeFw0yMjA0MjkwMzE0NTBa%0AFw0yMjA1MDIwMzE0NTBaMAAwWTATBgcqhkjOPQIBBggqhkjOPQMBBwNCAARVIZ7Y%0AZEXfbOGBfxGa7Vuok1MIng%2FuzLQK2xLVlSTIPDbO5hstTGP%2B%2FGx182PYFP3jYqk5%0Aq6rYWe1wiPNMA30Io4H8MIH5MA4GA1UdDwEB%2FwQEAwIDuDAdBgNVHSUEFjAUBggr%0ABgEFBQcDAgYIKwYBBQUHAwEwDAYDVR0TAQH%2FBAIwADApBgNVHQ4EIgQgrp4q50oX%0AHHghMbxz5Bk8OJFWMdfgH0Upr350WlhyxvkwKwYDVR0jBCQwIoAgUe6uERAIj%2FLM%0AyuFzDc3Wbp9TGAKBJYAwyhF14ToOQCMwYgYDVR0RAQH%2FBFgwVoZUc3BpZmZlOi8v%0AZWZhZDcyODItZDliMi0zMjk4LWY2ZDgtMzhiMzdmYjU4ZGYzLmNvbnN1bC9ucy9k%0AZWZhdWx0L2RjL2RjMS9zdmMvZGFzaGJvYXJkMAoGCCqGSM49BAMCA0cAMEQCIDwb%0AFlchufggNTijnQ5SUcvTZrWlZyq%2FrdVC20nbbmWLAiAVshNNv1xBqJI1NmY2HI9n%0AgRMfb8aEPVSuxEHhqy57eQ%3D%3D%0A-----END%20CERTIFICATE-----%0A";Subject="";URI=spiffe://efad7282-d9b2-3298-f6d8-38b37fb58df3.consul/ns/default/dc/dc1/svc/dashboard] ``` Closes #12852	3 years ago

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.	3 years ago
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.	3 years ago
R.B. Boyer	424f3cdd2c	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.	3 years ago

Freddy	00b5b0a0a2	Update filter chain creation for sidecar/ingress listeners (#11245) ... The duo of `makeUpstreamFilterChainForDiscoveryChain` and `makeListenerForDiscoveryChain` were really hard to reason about, and led to concealing a bug in their branching logic. There were several issues here: - They tried to accomplish too much: determining filter name, cluster name, and whether RDS should be used. - They embedded logic to handle significantly different kinds of upstream listeners (passthrough, prepared query, typical services, and catch-all) - They needed to coalesce different data sources (Upstream and CompiledDiscoveryChain) Rather than handling all of those tasks inside of these functions, this PR pulls out the RDS/clusterName/filterName logic. This refactor also fixed a bug with the handling of [UpstreamDefaults](https://www.consul.io/docs/connect/config-entries/service-defaults#defaults). These defaults get stored as UpstreamConfig in the proxy snapshot with a DestinationName of "*", since they apply to all upstreams. However, this wildcard destination name must not be used when creating the name of the associated upstream cluster. The coalescing logic in the original functions here was in some situations creating clusters with a `*.` prefix, which is not a valid destination.	3 years ago
