R.B. Boyer	71d45a3460	Support Incremental xDS mode (#9855 ) This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged. Union of all commit messages follows to give an overarching summary: xds: exclusively support incremental xDS when using xDS v3 Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail. Work around a strange older envoy behavior involving empty CDS responses over incremental xDS. xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead. Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client. xds: pull out checkStreamACLs method in advance of a later commit xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty. This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10. xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time	4 years ago

R.B. Boyer	398b766532	xds: default to speaking xDS v3, but allow for v2 to be spoken upon request (#9658 ) - Also add support for envoy 1.17.0	4 years ago
R.B. Boyer	3b6ffc447b	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	4 years ago

Daniel Nephin	75cbbe2702	config: add HookWeakDecodeFromSlice Currently opaque config blocks (config entries, and CA provider config) are modified by PatchSliceOfMaps, making it impossible for these opaque config sections to contain slices of maps. In order to fix this problem, any lazy-decoding of these blocks needs to support weak decoding of []map[string]interface{} to a struct type before PatchSliceOfMaps is replaces. This is necessary because these config blobs are persisted, and during an upgrade an older version of Consul could read one of the new configuration values, which would cause an error. To support the upgrade path, this commit first introduces the new hooks for weak decoding of []map[string]interface{} and uses them only in the lazy-decode paths. That way, in a future release, new style configuration will be supported by the older version of Consul. This decode hook has a number of advantages: 1. It no longer panics. It allows mapstructure to report the error 2. It no longer requires the user to declare which fields are slices of structs. It can deduce that information from the 'to' value. 3. It will make it possible to preserve opaque configuration, allowing for structured opaque config.	5 years ago
Freddy	9ed325ba8b	Enable gateways to resolve hostnames to IPv4 addresses (#7999 ) The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option. If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS. Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.	5 years ago

Chris Piraino	f3b54fa535	Allow configuration of upstream connection limits in Envoy (#6829 ) * Adds 'limits' field to the upstream configuration of a connect proxy This allows a user to configure the envoy connect proxy with 'max_connections', 'max_queued_requests', and 'max_concurrent_requests'. These values are defined in the local proxy on a per-service instance basis and should thus NOT be thought of as a global-level or even service-level value.	5 years ago
Freddy	fdd10dd8b8	Expose HTTP-based paths through Connect proxy (#6446 ) Fixes: #5396 This PR adds a proxy configuration stanza called expose. These flags register listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only listening on the loopback interface, while still accepting traffic from non Connect-enabled services. Under expose there is a boolean checks flag that would automatically expose all registered HTTP and gRPC check paths. This stanza also accepts a paths list to expose individual paths. The primary use case for this functionality would be to expose paths for third parties like Prometheus or the kubelet. Listeners for requests to exposed paths are be configured dynamically at run time. Any time a proxy, or check can be registered, a listener can also be created. In this initial implementation requests to these paths are not authenticated/encrypted.	5 years ago

Boyer	7a6faccf2f	docs: document how envoy escape hatches work with the discovery chain (#6350 ) - Bootstrap escape hatches are OK. - Public listener/cluster escape hatches are OK. - Upstream listener/cluster escape hatches are not supported. If an unsupported escape hatch is configured and the discovery chain is activated log a warning and act like it was not configured. Fixes #6160	5 years ago
