Derek Menteer	0094dbf312	Fix incorrect protocol for transparent proxy upstreams. (#17894 ) This PR fixes a bug that was introduced in: https://github.com/hashicorp/consul/pull/16021 A user setting a protocol in proxy-defaults would cause tproxy implicit upstreams to not honor the upstream service's protocol set in its `ServiceDefaults.Protocol` field, and would instead always use the proxy-defaults value. Due to the fact that upstreams configured with "tcp" can successfully contact upstream "http" services, this issue was not recognized until recently (a proxy-defaults with "tcp" and a listening service with "http" would make successful requests, but not the opposite). As a temporary work-around, users experiencing this issue can explicitly set the protocol on the `ServiceDefaults.UpstreamConfig.Overrides`, which should take precedence. The fix in this PR removes the proxy-defaults protocol from the wildcard upstream that tproxy uses to configure implicit upstreams. When the protocol was included, it would always overwrite the value during discovery chain compilation, which was not correct. The discovery chain compiler also consumes proxy defaults to determine the protocol, so simply excluding it from the wildcard upstream config map resolves the issue.	1 year ago

R.B. Boyer	6b4986907d	peering: ensure that merged central configs of peered upstreams for partitioned downstreams work (#17179 ) Partitioned downstreams with peered upstreams could not properly merge central config info (i.e. proxy-defaults and service-defaults things like mesh gateway modes) if the upstream had an empty DestinationPartition field in Enterprise. Due to data flow, if this setup is done using Consul client agents the field is never empty and thus does not experience the bug. When a service is registered directly to the catalog as is the case for consul-dataplane use this field may be empty and and the internal machinery of the merging function doesn't handle this well. This PR ensures the internal machinery of that function is referentially self-consistent.	2 years ago
Paul Glass	77ecff3209	Permissive mTLS (#17035 ) This implements permissive mTLS , which allows toggling services into "permissive" mTLS mode. Permissive mTLS mode allows incoming "non Consul-mTLS" traffic to be forward unmodified to the application. * Update service-defaults and proxy-defaults config entries with a MutualTLSMode field * Update the mesh config entry with an AllowEnablingPermissiveMutualTLS field and implement the necessary validation. AllowEnablingPermissiveMutualTLS must be true to allow changing to MutualTLSMode=permissive, but this does not require that all proxy-defaults and service-defaults are currently in strict mode. * Update xDS listener config to add a "permissive filter chain" when MutualTLSMode=permissive for a particular service. The permissive filter chain matches incoming traffic by the destination port. If the destination port matches the service port from the catalog, then no mTLS is required and the traffic sent is forwarded unmodified to the application.	2 years ago
Derek Menteer	1bcaeabfc3	Remove deprecated service-defaults upstream behavior. (#16957 ) Prior to this change, peer services would be targeted by service-default overrides as long as the new `peer` field was not found in the config entry. This commit removes that deprecated backwards-compatibility behavior. Now it is necessary to specify the `peer` field in order for upstream overrides to apply to a peer upstream.	2 years ago

Derek Menteer	2facf50923	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.	2 years ago

Derek Menteer	418bd62c44	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.

Dan Upton	7b2d08d461	chore: remove unused argument from MergeNodeServiceWithCentralConfig (#15024 ) Previously, the MergeNodeServiceWithCentralConfig method accepted a ServiceSpecificRequest argument, of which only the Datacenter and QueryOptions fields were used. Digging a little deeper, it turns out these fields were only passed down to the ComputeResolvedServiceConfig method (through the ServiceConfigRequest struct) which didn't actually use them. As such, not all call-sites passed a valid ServiceSpecificRequest so it's safer to remove the argument altogether to prevent future changes from depending on it.	2 years ago

Daniel Upton	a31738f76f	proxycfg-glue: server-local implementation of ResolvedServiceConfig This is the OSS portion of enterprise PR 2460. Introduces a server-local implementation of the proxycfg.ResolvedServiceConfig interface that sources data from a blocking query against the server's state store. It moves the service config resolution logic into the agent/configentry package so that it can be used in both the RPC handler and data source. I've also done a little re-arranging and adding comments to call out data sources for which there is to be no server-local equivalent.	2 years ago

R.B. Boyer	7b0548dd8d	server: suppress spurious blocking query returns where multiple config entries are involved (#12362 ) Starting from and extending the mechanism introduced in #12110 we can specially handle the 3 main special Consul RPC endpoints that react to many config entries in a single blocking query in Connect: - `DiscoveryChain.Get` - `ConfigEntry.ResolveServiceConfig` - `Intentions.Match` All of these will internally watch for many config entries, and at least one of those will likely be not found in any given query. Because these are blends of multiple reads the exact solution from #12110 isn't perfectly aligned, but we can tweak the approach slightly and regain the utility of that mechanism. ### No Config Entries Found In this case, despite looking for many config entries none may be found at all. Unlike #12110 in this scenario we do not return an empty reply to the caller, but instead synthesize a struct from default values to return. This can be handled nearly identically to #12110 with the first 1-2 replies being non-empty payloads followed by the standard spurious wakeup suppression mechanism from #12110. ### No Change Since Last Wakeup Once a blocking query loop on the server has completed and slept at least once, there is a further optimization we can make here to detect if any of the config entries that were present at specific versions for the prior execution of the loop are identical for the loop we just woke up for. In that scenario we can return a slightly different internal sentinel error and basically externally handle it similar to #12110. This would mean that even if 20 discovery chain read RPC handling goroutines wakeup due to the creation of an unrelated config entry, the only ones that will terminate and reply with a blob of data are those that genuinely have new data to report. ### Extra Endpoints Since this pattern is pretty reusable, other key config-entry-adjacent endpoints used by `agent/proxycfg` also were updated: - `ConfigEntry.List` - `Internal.IntentionUpstreams` (tproxy)	3 years ago
