xds: Consistency while handling CDS updates and EDS #13009
Comments

CC @envoyproxy/api-shepherds |
Why would the management server need to send an update for the EDS resource that has not changed, just because the CDS resource that pointed to it has changed? This seems like a pretty clear Envoy bug: the CDS and EDS resources should be tracked independently from the perspective of the xDS client code, so that when a new Cluster object is created, it can just pick up the existing data for the EDS resource it wants. In gRPC, the pattern we use here is to separate out the transport protocol logic from the data model logic. The transport protocol logic (which includes not just the wire communication but also the caching logic, since those two things are ultimately closely tied together) is implemented in a single XdsClient object. Its API allows callers to start watches for a given resource of a given type. When the first watch for a given resource is started, the XdsClient will send a request to the xDS server subscribing to that resource, and all updates from the xDS server will be sent to that watcher. It's fine for multiple callers to be watching the same resource: if a watch is started for a resource that is already subscribed to (because some other watch was already started), then the XdsClient will immediately send the already-cached data to the new watcher. When all watchers for a given resource are cancelled, the XdsClient will send a request to the xDS server unsubscribing from that resource. One significant difference between Envoy and gRPC is that when a CDS resource is updated, gRPC can update the individual fields in the cluster instance rather than having to create a whole new cluster instance. But even if we did need to create a whole new cluster instance, it still would not pose a problem, because we'd keep the old instance around while the new instance warmed up. This would mean that when the new instance would start a watch for the EDS resource name, it would get the value that was already cached in the XdsClient, and the management server would not know or care that the cluster instance had been replaced.
This seems sub-optimal, both because it will cause unnecessary network traffic and because it will make warming the new cluster instance take longer. I think it should be possible to avoid all of that by separating out the xDS client code into its own layer, as I described above. That having been said, my concern here is less about Envoy having sub-optimal behavior and more about making sure that the protocol semantics are clear. I think that the protocol itself should not require clients to re-subscribe in this case, because I'd rather not change gRPC, which already handles this case correctly, to do something less optimal. And if Envoy does do the less optimal thing, I am concerned that it may introduce situations where management servers are built with Envoy-specific assumptions that make it hard for them to support gRPC later. |

@markdroth I think this was a deliberate choice we made when designing CDS warming. The idea is that you might also be switching the endpoints when changing cluster config, e.g. upgrading from non-TLS to TLS cluster. You can see a pretty detailed discussion in #5168. On clarifying protocol semantics, I think we have a PoR to move forward here with #11299. I'll be putting together a SoW draft for this during the week. This is probably the best way to get a formal and testable statement of intended semantics in these corner cases. |
|
Reading the discussion in #5168, the problem there actually seems like another symptom of the fact that Envoy's implementation does not cleanly separate the transport protocol layer (which by necessity includes caching) from the data model layer (in this case, the cluster instance). IMHO, these should be two different layers with a clear separation between them, so that implementation details in the data model layer (such as completely replacing a cluster instance whenever one field changes) do not affect the behavior of the transport protocol layer (such as caching). To say that another way, I think that the existence of this issue is an indication that the existing solution to #5168 didn't really solve the problem. I think that if Envoy changed to cleanly separate these two layers, it would not only solve the immediate problem but also prevent future problems caused by this same underlying architectural problem. In fact, it looks to me like you actually suggested something similar to this in #5168 (comment), and I don't see any follow-up discussion there saying why this should not work. I see that you said that it seems odd to do this in the gRPC mux impl, which I can understand, but I don't see why we can't wrap a fuller XdsClient abstraction around the gRPC mux impl. |

@htuch if one were to make something like change TLS without downtime, we now have |
|
BTW, if you're interested in what the XdsClient API looks like in gRPC, the relevant part is here: In our implementation, there's a separate watch API for each type of resource, mainly because we can't depend on the protobuf library and didn't want to make upb part of this API. But in Envoy, you could easily have a single watch API used for all resource types, simply by specifying the resource type as a parameter when you start the watch and having the data reported to the watcher be an |

I'm with @markdroth here. I think from a protocol standpoint it pretty crappy for mangement servers to have to resend a configuration change if nothing really changed. Furthermore, in Incremental, Envoy is subscribed to resource updates and should only get notifiend when those actually change. In the case of updating clusters to TLS, if it's not doable with current mechanics, maybe we're in need of additional methods for transparently doing this sort of updates, but it would seem that |
|
As in the original CDS work, our constraints are not greenfield, to some extent we need to be backwards compatible with existing management servers. I don't think it would be particularly hard to add caching to Envoy's existing implementation, the question is really what is the correct behavior on the wire, given Envoy's existing behavior, xDS server implementations and our desired goals. We've been running with the "CDS updates implies warming, implies an EDS response" for some time. Can we design something that works for folks who are assuming that and migrate to a better model? Potentially, but I don't think we can sunset Envoy's cluster warming behavior overnight. |
|
If Envoy stops requiring management servers to proactively send an EDS response after a CDS update, then it's not harmful for management servers that continue to do that (the update will effectively be a no-op on the client if nothing has changed), but it means that new management servers don't need to send that unnecessary update. |
|
One thing I'd like to point out, going all the way back to the top of this thread, is that in Envoy today, what is going on, is that a cluster is going away and a new one is arriving, which happens to share the same name. When you delete a resource, in CDS, you logically unsubscribe from the EDS resources. We could special case this to talk about what happens over an update, but keep in mind we're adding in an extra corner case to deal with in implementations. I'm not opposed to any direction we take here. IMHO, the most logical thing would be for subscriptions to actually references the subscribing resource instance (e.g. via UUID), so that you could independently unsubscribe and resubscribe. But I don't think it's worth building that out just for this. |
It's not as simple as this, since some Envoy users will be expecting the warming behavior and want to defer the cluster warming until endpoint update. See the TLS upgrade example, which is not a hypothetical but a valid use of Envoy's existing mechanisms. |
|
Also worth keeping in mind, this is not some undocumented behavior that people happen to be relying on, we've been guaranteeing this for some time, see https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/upstream/cluster_manager.html?highlight=warming#cluster-warming |
I think the right way to model this is to say that the implicit deletion of RDS and EDS resources happens at the transport protocol layer, not at the data model layer -- which makes sense if you think about it, because this deletion is a cache operation, and caching is dictated by the transport protocol, not the data model. In other words, inside of the XdsClient, when we receive a CDS update that removes a CDS resource, we remove the cached EDS resource that was referred to by the removed CDS resource, and we notify any watchers of that EDS resource that the resource no longer exists. It should not be tied to the deletion of the data model object (the cluster instance) at all. What this means is that when the XdsClient sees an updated CDS resource that changes some field other than the EDS service name, it knows that the EDS resource is still referenced and is therefore not being deleted. The fact that Envoy will create a new cluster instance and destroy the old one at the data model layer should be irrelevant to that decision. (Also, as we've discussed separately, I think that the implicit deletion of the RDS and EDS resources is a very ugly layering violation, specifically because it does require the transport protocol layer to know something about the relationship between the resources, which is really a data model concern. IMHO we should remove this behavior as part of moving to the incremental protocol variants, which will make the layering cleaner here.)
Interesting. I agree, that will definitely make it harder to get rid of this. Hmmm... If management servers expect clients to not use the existing EDS data after a CDS update, is it going to cause problems that gRPC will use that existing data? What if a management server is intentionally sending a CDS update that requires drastically different EDS data? For example, if the CDS update switches from plaintext to TLS, and the EDS update points to a new set of endpoints that speak TLS? This behavior seems like a clear layering violation and is extremely difficult to reason about. I really don't want to implement it in gRPC. I think this is going to cause problems if we don't clean this up. |
|
Note that if we can find a way to get rid of the existing behavior, then in cases where a management server does not want the new cluster instance to use the old EDS data, it can always use a new EDS service name in the updated CDS resource. |
|
I see this less as a layering violation as an attempt to bolt on consistency to an eventually consistent model. What warming on EDS is currently doing is saying "we may know the old EDS, but we want another EDS that is temporally fresher than this older one" (if you ignore my cluster actor model above and think purely in transport terms). Which might not even be true in an eventually consistent environment (i.e. not ADS), your warming EDS might be some delayed EDS update of data older than the cluster. We've discussed trying to explicitly add in a notion of version dependency in the past, this probably isn't the right time to add it, but if we did have that, then it would be a lot clearer what is going on. I agree it's pretty broken and hard to deal with. Maybe one path forward here is to add explicit fields to |
|
@htuch @markdroth I am very far from what you both discuss about separating data model and transport model, but - from what I see in APIs perspective - it basically says that dependencies between resources are described in terms of names. This "warming" thing from APIs perspective look like an implementation detail of envoy that is simply not possible to describe in terms of what API provides: cluster has changed, it's name is the same, management server's state from endpoints perspective has not changed - no updates by default should be here. |
|
@fxposter Envoy just cares that it sees an EDS update after the CDS update, not which cluster it relates to. I don't see this as an Envoy implementation detail, this is clearly specified in the docs which are part of what currently constitutes the API for folks building control planes. |
That might very well be a useful migration path. We could do a phased migration where we initially leave the default alone but provide the field to request the new behavior, then change the default but allow it to be disabled via the field, and then finally remove the field completely. I just want to make sure that we wind up in a plce where this kind of layering violation is not supported. Otherwise, we will never have a clean separation between the transport protocol and the data model. |
|
As discussed with @markdroth offline, this is an area of xDS that is super confusing when we consider the mix of SotW, delta, ADS and non-ADS, different consistency models. From the above thread, it's also apparent that the current behavior is not well understood. I think we should put together a uRFC https://github.com/cncf/udpa/tree/master/proposals to clarify what the existing behavior is and what we want the future behavior to be, without breaking backwards compatibility for existing use cases where the current behavior makes sense. |
|
@htuch I mean a bit different thing. If this feature is intended for envoy not using "partially constructed" clusters in this particular case - then if there are multiple updates to the same cluster - when you receive an update to corresponding endpoints - you still don't know which cluster state that update of endpoints is related. And yes - "warming" will succeed, but it may succeed with wrong state. ie: if cluster states (for single particular cluster) are CS1, CS2, CS3... and corresponding "good" endpoint states are ES1, ES2, ES3... Then if you receive an almost simultaneous updates "-> CS2" and "->CS3" - CDS will require warmup for "CS3" state. And if afterwards envoy receives state "ES2" and later "ES3", I can guess the first "fully constructed state" will be (CS3 + ES2), which might be incorrect. |
|
@fxposter yes, unless you linearize on ADS you can get various kinds of races happening. This is what I was referring to when the ADS vs. non-ADS case being also pretty confusing above. |
|
Here's my concrete proposal (which should be turned into a uRFC):
None of this will change existing behaviors of LDS, CDS, etc. since we will potentially break folks who are relying on the existing warming behaviors. |
|
I think that's a fine proposal, but I would also like to see a migration path for fully eliminating the problematic behavior. If we don't define such a path, we'll never be rid of it. |
|
@htuch shouldn't this also consider |
|
The proposal in #13009 (comment) SGTM. We can discuss the exact field name, etc. in code review. I agree overall that this is an incredibly confusing detail that has tripped a lot of people up and we should fix this.
On the Envoy side we can talk about potentially flipping the default for the field, but we would have to give a lot of warning, runtime revert support, etc. as we have a large number of management servers in the wild that might break. |
|
FWIW, #6021 implemented 1 on the proposal above |
|
FWIW, I agree that the semantics of ACK vs. request in the transport protocol could be made clearer, and I think that's something we should work on. However, as @htuch said, I think that's a separate problem from the caching functionality that is the subject of this issue. In this case, there should not be a subsequent request in the first place, because the client should not be re-requesting a resource that it is already subscribed to. I think we should add caching to solve that problem rather than trying to hack in some way for the client to re-request something that it should already have. |

Any way could prevent the hack judgement in istio |

This fixes the following race condition: - Send update endpoints - Send update cluster - Recv ACK endpoints - Recv ACK cluster Prior to this fix, it would have resulted in the endpoints NOT existing in Envoy. This occurred because the cluster update implicitly clears the endpoints in Envoy, but we would never re-send the endpoint data to compensate for the loss, because we would incorrectly ACK the invalid old endpoint hash. Since the endpoint's hash did not actually change, they would not be resent. The fix for this is to effectively clear out the invalid pending ACKs for child resources whenever the parent changes. This ensures that we do not store the child's hash as accepted when the race occurs. An escape-hatch environment variable `XDS_PROTOCOL_LEGACY_CHILD_RESEND` was added so that users can revert back to the old legacy behavior in the event that this produces unknown side-effects. Visit the following thread for some extra context on why certainty around these race conditions is difficult: envoyproxy/envoy#13009 This bug report and fix was mostly implemented by @ksmiley with some minor tweaks.

For now the format of queries is: <service>--<namespace>--<partition>.virtual.consul Additionally: - All transparent proxy enabled services are assigned a virtual ip in the 10.244.0/24 range. This is something Consul will do in v2 at a later date, likely during 1.18. - All services with exposed ports (non-mesh) are assigned a virtual port number for use with tproxy - The consul-dataplane image has been made un-distroless, and gotten the necessary tools to execute consul connect redirect-traffic before running dataplane, thus simulating a kubernetes init container in plain docker. * update v2 changelog (#19446) * NET-6319 - L7 routes have statePrefix of upstream. and should have a full path (#19473) * resource: finalizer aware delete endpoint (2 of 5) (#19493) resource: make delete endpoint finalizer aware * build: dependency updates for 1.17.0 (#19453) * chore: apply enterprise changes that were missed to some testing files (#19504) This should align between CE ef35525 and ENT 7f95226dbe40151c8f17dd4464784b60cf358dc1 in: - testing/integration/consul-container - test-integ - testing/deployer * Net-6291/fix/watch resources (#19467) * fix: update watch endpoint to default based on scope * test: additional test * refactor: rename list validate function * refactor: rename validate<Op>Request() -> ensure<Op>RequestValid() for consistency * XDS V1 should not make runs for TCP Disco Chains.

Prior to this commit, the connection pools were unaware which datacenter the connection was associated with. This meant that any time servers with overlapping LAN IP addresses and node shortnames existed, they would be incorrectly co-located in the same pool. Whenever this occurred, the servers would get stuck in an infinite loop of forwarding RPCs to themselves (rather than the intended remote DC) until they eventually run out of memory. Most notably, this issue can occur whenever wan federation through mesh gateways is enabled. This fix adds extra metadata to specify which DC the connection is associated with in the pool. * CC-5545: Side Nav (#19342) * Initial work for sidenav * Use HDS::Text * Add resolution for ember-element-helper * WIP dc selector * Update HCP Home link * DC selector * Hook up remaining selectors * Fix settings and tutorial links * Remove comments * Remove skip-links * Replace auth with new dropdown * Use href-to helper for sidenav links * Changelog * Add description to NavSelector * Wrap version in footer and role * Fix login tests * Add data-test selectors for namespaces * Fix datacenter disclosure menu test * Stop rendering auth dialog if acls are disabled * Update disabled selector state and token selector * Fix logic in ACL selector * Fix HCP Home integration test * Remove toggling the sidenav in tests * Add sidenav to eng docs * Re-add debug navigation for eng docs * Remove ember-in-viewport * Remove unused styles * Upgrade @hashicorp/design-system-componentseee * Add translations for side-nav * Only show back to hcp link if url is present * Disable responsive due to a11y-dialog issue * fixed typos in redirect for api gateways (#19526) * fixed typos in redirect for api gateways * one more typo * final typo * [NET-5916] Update locality-aware routing docs (#19529) * docs: Update locality-aware routing docs - Align locality-aware routing documentation to the recommended use of the feature and incorporate engineer feedback. - Remove docs for unreleased multi-cluster failover feature. - Fix minor typos and formatting in examples. * docs: Fix rate limit docs typo * [NET-5916] docs: Remove locality proxy startup section (#19534) docs: Remove locality proxy startup section This section is not necessary as it is not unique to the feature.

(#19393) As the V2 architecture hinges on eventual consistency and controllers reconciling the existing state in response to writes, there are potential issues we could run into regarding ordering and timing of operations. We want to be able to guarantee that given a set of resources the system will always eventually get to the desired correct state. The order of resource writes and delays in performing those writes should not alter the final outcome of reaching the desired state. To that end, this commit introduces arbitrary randomized delays before performing resources writes into the `resourcetest.Client`. Its `PublishResources` method was already randomizing the order of resource writes. By default, no delay is added to normal writes and deletes but tests can opt-in via either passing hard coded options when creating the `resourcetest.Client` or using the `resourcetest.ConfigureTestCLIFlags` function to allow processing of CLI parameters. In addition to allowing configurability of the request delay min and max, the client also has a configurable random number generator seed. When Using the CLI parameter helpers, a test log will be written noting the currently used settings. If the test fails then you can reproduce the same delays and order randomizations by providing the seed during the previous test failure. * Migrate individual resource tests for custom configuration to TestAllResourcesFromSnapshot (#19512) * Configure TestAllResourcesFromSnapshot to run V2 tests * migrate custom configuration tests to resources_test.go * Update Helm docs for consul-k8s 1.3.0 (#19581) * Migrate individual resource tests for JWT Provider to TestAllResourcesFromSnapshot (#19511) migrate jwt provider tests to resources_test.go * Fix xds v2 from creating envoy endpoint resources when already inlined in the cluster (#19580) * migrate expose checks and paths tests to resources_test.go * fix failing expose paths tests * fix the way endpoint resources get created to make expose tests pass. * wip * remove endpoint resources that are already inlined on local_app clusters * renaiming and comments * test: add a v2 container integration test of xRoute splits (#19570) This adds a deployer-based integration test verifying that a 90/10 traffic split works for: HTTPRoute, GRPCRoute, and TCPRoute. * docs: spike of info about how to use deployer topology tests (#19576) Initial developer facing docs on how to write deployer (topology) integration tests. * Net 6439 (#19517) * node health controller tenancy * some prog * some fixes * revert * pr comment resolved * removed name * Add namespace and tenancy in sidecar proxy controller test * revert node health controller * clean up data * fix local * copy from ENT * removed dup code * removed tenancy * add test tenancies * Migrate individual resource tests for Terminating Gateway to TestAllResourcesFromSnapshot (#19505) migrate terminating-gateway tests to resources_test.go * Migrate individual resource tests for Ingress Gateway to TestAllResourcesFromSnapshot (#19506) migrate ingress-gateway tests to resources_test.go * Update links and fix route kind for APIGW JWT Docs (#19585) Update links and fix route kind * Migrate individual resource tests for Mesh Gateway to TestAllResourcesFromSnapshot (#19502) migrate mesh-gateway tests to resources_test.go * Migrate individual resource tests for API Gateway to TestAllResourcesFromSnapshot (#19584) migrate individual api gateway tests to resources_test.go * toil: use pre-commit to maintain properly formatted imports (#17940) pro-tip: you can skip this check with `git commit --no-verify` to override * [NET-6356] Add tenancy to Failover Tests (#19547) * [NET-6356] Add tenancy to Failover Tests * [NET-6438] Add tenancy to xDS Tests -

(#19866) This fixes the following race condition: - Send update endpoints - Send update cluster - Recv ACK endpoints - Recv ACK cluster Prior to this fix, it would have resulted in the endpoints NOT existing in Envoy. This occurred because the cluster update implicitly clears the endpoints in Envoy, but we would never re-send the endpoint data to compensate for the loss, because we would incorrectly ACK the invalid old endpoint hash. Since the endpoint's hash did not actually change, they would not be resent. The fix for this is to effectively clear out the invalid pending ACKs for child resources whenever the parent changes. This ensures that we do not store the child's hash as accepted when the race occurs. An escape-hatch environment variable `XDS_PROTOCOL_LEGACY_CHILD_RESEND` was added so that users can revert back to the old legacy behavior in the event that this produces unknown side-effects. Visit the following thread for some extra context on why certainty around these race conditions is difficult: https://github.com/envoyproxy/envoy/issues/13009 This bug report and fix was mostly implemented by @ksmiley with some minor tweaks.

(#19871) When a large number of upstreams are configured on a single envoy proxy, there was a chance that it would timeout when waiting for ClusterLoadAssignments. While this doesn't always immediately cause issues, consul-dataplane instances appear to consistently drop endpoints from their configurations after an xDS connection is re-established (the server dies, random disconnect, etc). This commit adds an `xds_fetch_timeout_ms` config to service registrations so that users can set the value higher for large instances that have many upstreams. The timeout can be disabled by setting a value of `0`. This configuration was introduced to reduce the risk of causing a breaking change for users if there is ever a scenario where endpoints would never be received. Rather than just always blocking indefinitely or for a significantly longer period of time, this config will affect only the service instance associated with it. * [NET-6842] splitting go version on different lines (#19887) * Add documentation for proxy-config-map and xds_fetch_timeout_ms.

It appears that when a cluster is updated without a following endpoint update a cluster can lose its endpoint configuration. I attempted to update endpoints on each cluster change to prevent this but it was still possible for the cluster update to happen after the endpoint update. This appears related to envoyproxy/envoy#13009 By using static clusters the endpoints are included in the cluster update. In testing this appears to resolve the issue where endpoints disappear since we no longer rely on EDS.
When a cluster is created or updated envoy it enters warming phase and needs a related ClusterLoadAssignement response to fully initialize.
During Envoy startup phase envoy sends requests for those resources to the management server and so the management servers knows it has to respond those.
But, when updating a Cluster via CDS, no EDS re-request is sent to the management server and management server doesn't really know it should send a ClusterLoadAssignement for that Cluster, even if the resource hasn't really changed.
This berhavior introduces subtle bugs in management servers, in our case, our resource versioning scheme somehow included the cluster version, yesterday we introduced a change to remove that, and that unexpectedly broke our cluster updates, leaving some clusters without traffic.
This should probably be handled by envoy, currently go-control-plane and java-control-plane don't really handle this since it's kind of hard to induce this behavior of always pushing an EDS update for a Cluster even if the resource hasn't really changed, and if not using ADS, envoy is possibly connected to multiple management servers which increases the difficulty.
@htuch suggested that envoy should probably unsubscribe from EDS for the updated cluster and immediately subscribe again, since this is what's actually happening inside envoy, a new Cluster is being created and it wants to subscribe to the resources, and the old one wants to unsubscribe. Some more thought should be done on this idea and the consecuences of the old cluster being unsubscribed from resources.
Some discussion already happened on Slack, opening this issue to continue discussion.
This issue also applies to LDS updates with RDS and probably SRDS with RDS.
