Daniel Nephin dfa8856e5f agent/consul: Add support for NotModified to two endpoints
A query made with AllowNotModifiedResponse and a MinIndex, where the
result has the same Index as MinIndex, will return an empty response
with QueryMeta.NotModified set to true.

connect: various changes to make namespaces for intentions work more like for other subsystems (#8194)
Highlights:

- add new endpoint to query for intentions by exact match

- using this endpoint from the CLI instead of the dump+filter approach

- enforcing that OSS can only read/write intentions with a SourceNS or
  DestinationNS field of "default".

- preexisting OSS intentions with now-invalid namespace fields will
  delete those intentions on initial election or for wildcard namespaces
  an attempt will be made to downgrade them to "default" unless one
  exists.

- also allow the '-namespace' CLI arg on all of the intention subcommands

- update lots of docs

Split up unused key validation for oss/ent (#8189)
Split up unused key validation in config entry decode for oss/ent.

This is needed so that we can return an informative error in OSS if namespaces are provided.

Chris Piraino abe2ca94c5 Update gateway-services-nodes API endpoint to allow multiple addresses
Previously, we were only returning a single ListenerPort for a single
service. However, we actually allow a single service to be serviced over
multiple ports, as well as allow users to define what hostnames they
expect their services to be contacted over. When no hosts are defined,
we return the default ingress domain for any configured DNS domain.

To show this in the UI, we modify the gateway-services-nodes API to
return a GatewayConfig.Addresses field, which is a list of addresses
over which the specific service can be contacted.

ACL Node Identities (#7970)
A Node Identity is very similar to a service identity. Its main targeted use is to allow creating tokens for use by Consul agents that will grant the necessary permissions for all the typical agent operations (node registration, coordinate updates, anti-entropy).

Half of this commit is for golden file based tests of the acl token and role cli output. Another big updates was to refactor many of the tests in agent/consul/acl_endpoint_test.go to use the same style of tests and the same helpers. Besides being less boiler plate in the tests it also uses a common way of starting a test server with ACLs that should operate without any warnings regarding deprecated non-uuid master tokens etc.

config: Use HookWeakDecodeFromSlice in place of PatchSliceOfMaps
2020-06-08 19:53:04 -04:00
Daniel Nephin 7b99d9a25d 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.

Daniel Nephin b9e4544ec3 intentions: fix a bug in Intention.SetHash
Found using staticcheck.

binary.Write does not accept int types without a size. The error from binary.Write was ignored, so we never saw this error. Casting the data to uint64 produces a correct hash.

Also deprecate the Default{Addr,Port} fields, and prevent them from being encoded. These fields will always be empty and are not used.
Removing these would break backwards compatibility, so they are left in place for now.

Replace goe/verify.Values with testify/require.Equal (#7993)
* testing: replace most goe/verify.Values with require.Equal

One difference between these two comparisons is that go/verify considers
nil slices/maps to be equal to empty slices/maps, where as testify/require
does not, and does not appear to provide any way to enable that behaviour.

Because of this difference some expected values were changed from empty
slices to nil slices, and some calls to verify.Values were left.

* Remove github.com/pascaldekloe/goe/verify

Reduce the number of assertion packages we use from 2 to 1

Daniel Nephin ea6c2b2adc ci: Add staticcheck and fix most errors
Three of the checks are temporarily disabled to limit the size of the
diff, and allow us to enable all the other checks in CI.

In a follow up we can fix the issues reported by the other checks one
at a time, and enable them.

Daniel Nephin c2499418ed test: Remove t.Parallel() from agent/structs tests
go test will only run tests in parallel within a single package. In this case the package test run time is exactly the same with or without t.Parallel() (~0.7s).

In generally we should avoid t.Parallel() as it causes a number of problems with `go test` not reporting failure messages correctly. I encountered one of these problems, which is what prompted this change.  Since `t.Parallel` is not providing any benefit in this package, this commit removes it.

The change was automated with:

    git grep -l 't.Parallel' | xargs sed -i -e '/t.Parallel/d'

We can only allow host names that are valid domain names because we put

specifier '*' is only present as the leftmost label to allow for a
wildcard DNSSAN and associated wildcard Host routing in the ingress
gateway proxy.

Kyle Havlovitz b21cd112e5 Allow ingress gateways to route traffic based on Host header
This commit adds the necessary changes to allow an ingress gateway to
route traffic from a single defined port to multiple different upstream
services in the Consul mesh.

To do this, we now require all HTTP requests coming into the ingress
gateway to specify a Host header that matches "<service-name>.*" in
order to correctly route traffic to the correct service.

- Differentiate multiple listener's route names by port
- Adds a case in xds for allowing default discovery chains to create a
  route configuration when on an ingress gateway. This allows default
  services to easily use host header routing
- ingress-gateways have a single route config for each listener
  that utilizes domain matching to route to different services.
