* Support Vault Namespaces explicitly in CA config
If there is a Namespace entry included in the Vault CA configuration,
set it as the Vault Namespace on the Vault client
Currently the only way to support Vault namespaces in the Consul CA
config is by doing one of the following:
1) Set the VAULT_NAMESPACE environment variable which will be picked up
by the Vault API client
2) Prefix all Vault paths with the namespace
Neither of these are super pleasant. The first requires direct access
and modification to the Consul runtime environment. It's possible and
expected, not super pleasant.
The second requires more indepth knowledge of Vault and how it uses
Namespaces and could be confusing for anyone without that context. It
also infers that it is not supported

To make it more clear which methods are necessary for each scenario. This can
also prevent problems which force all DCs to use the same Vault instance, which
is currently a problem.
* ca: move provider creation into CAManager
This further decouples the CAManager from Server. It reduces the interface between them and
removes the need for the SetLogger method on providers.
* ca: move SignCertificate to CAManager
To reduce the scope of Server, and keep all the CA logic together
* ca: move SignCertificate to the file where it is used
* auto-config: move autoConfigBackend impl off of Server
Most of these methods are used exclusively for the AutoConfig RPC
endpoint. This PR uses a pattern that we've used in other places as an
incremental step to reducing the scope of Server.

As part of this change, we ensure that the SAN extensions are marked as
critical when the subject is empty so that AWS PCA tolerates the loss of
common names well and continues to function as a Connect CA provider.
Parts of this currently hack around a bug in crypto/x509 and can be
removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.
Note: the AWS PCA tests do not run automatically, but the following
passed locally for me:
ENABLE_AWS_PCA_TESTS=1 go test ./agent/connect/ca -run TestAWS
With an optional interface that providers can use to indicate if they
use an intermediate cert in the primary DC.
This removes the need to look up the provider config when renewing the
intermediate.
After fixing that bug I uncovered a couple more:
Fix an issue where we might try to cross sign a cert when we never had a valid root.
Fix a potential issue where reconfiguring the CA could cause either the Vault or AWS PCA CA providers to delete resources that are still required by the new incarnation of the CA.
Add a skip condition to all tests slower than 100ms.
This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests
With this change:
```
$ time go test -count=1 -short ./agent
ok github.com/hashicorp/consul/agent 0.743s
real 0m4.791s
$ time go test -count=1 -short ./agent/consul
ok github.com/hashicorp/consul/agent/consul 4.229s
real 0m8.769s
```
* fix lessThanHalfTime
* get lock for CAProvider()
* make a var to relate both vars
* rename to getCAProviderWithLock
* move CertificateTimeDriftBuffer to agent/connect/ca
The fallback method would still work but it would get into a state where it would let the certificate expire for 10s before getting a new one. And the new one used the less secure RPC endpoint.
This is also a pretty large refactoring of the auto encrypt code. I was going to write some tests around the certificate monitoring but it was going to be impossible to get a TestAgent configured in such a way that I could write a test that ran in less than an hour or two to exercise the functionality.
Moving the certificate monitoring into its own package will allow for dependency injection and in particular mocking the cache types to control how it hands back certificates and how long those certificates should live. This will allow for exercising the main loop more than would be possible with it coupled so tightly with the Agent.
To reduce the chance of some tests not being run because it does not
match the regex passed to '-run'.
Also document why some tests are allowed to be skipped on CI.
If the CI environment is not correct for running tests the tests
should fail, so that we don't accidentally stop running some tests
because of a change to our CI environment.
Also removed a duplicate delcaration from init. I believe one was
overriding the other as they are both in the same package.
We set RawToString=true so that []uint8 => string when decoding an interface{}.
We set the MapType so that map[interface{}]interface{} decodes to map[string]interface{}.
Add tests to ensure that this doesn't break existing usages.
Fixes#7223
Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates.
This PR adds a check that renews the cert if it is half way through its validity period.
In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.
* Add CreateCSRWithSAN
* Use CreateCSRWithSAN in auto_encrypt and cache
* Copy DNSNames and IPAddresses to cert
* Verify auto_encrypt.sign returns cert with SAN
* provide configuration options for auto_encrypt dnssan and ipsan
* rename CreateCSRWithSAN to CreateCSR
* Renamed structs.IntentionWildcard to structs.WildcardSpecifier
* Refactor ACL Config
Get rid of remnants of enterprise only renaming.
Add a WildcardName field for specifying what string should be used to indicate a wildcard.
* Add wildcard support in the ACL package
For read operations they can call anyAllowed to determine if any read access to the given resource would be granted.
For write operations they can call allAllowed to ensure that write access is granted to everything.
* Make v1/agent/connect/authorize namespace aware
* Update intention ACL enforcement
This also changes how intention:read is granted. Before the Intention.List RPC would allow viewing an intention if the token had intention:read on the destination. However Intention.Match allowed viewing if access was allowed for either the source or dest side. Now Intention.List and Intention.Get fall in line with Intention.Matches previous behavior.
Due to this being done a few different places ACL enforcement for a singular intention is now done with the CanRead and CanWrite methods on the intention itself.
* Refactor Intention.Apply to make things easier to follow.
* Update AWS SDK to use PCA features.
* Add AWS PCA provider
* Add plumbing for config, config validation tests, add test for inheriting existing CA resources created by user

This only works so long as we use simplistic protobuf types. Constructs such as oneof or Any types that require type annotations for decoding properly will fail hard but that is by design. If/when we want to use any of that we will probably need to consider a v2 API.
* Add JSON and Binary Marshaler Generators for Protobuf Types
* Generate files with the correct version of gogo/protobuf
I have pinned the version in the makefile so when you run make tools you get the right version. This pulls the version out of go.mod so it should remain up to date.
The version at the time of this commit we are using is v1.2.1
* Fixup some shell output
* Update how we determine the version of gogo
This just greps the go.mod file instead of expecting the go mod cache to already be present
* Fixup vendoring and remove no longer needed json encoder functions
This fixes an issue where leaf certificates issued in secondary
datacenters would be reissued very frequently (every ~20 seconds)
because the logic meant to detect root rotation was errantly triggering
because a hash of the ultimate root (in the primary) was being compared
against a hash of the local intermediate root (in the secondary) and
always failing.
The fields in the certs are meant to hold the original binary
representation of this data, not some ascii-encoded version.
The only time we should be colon-hex-encoding fields is for display
purposes or marshaling through non-TLS mediums (like RPC).
This only affects vault versions >=1.1.1 because the prior code
accidentally relied upon a bug that was fixed in
https://github.com/hashicorp/vault/pull/6505
The existing tests should have caught this, but they were using a
vendored copy of vault version 0.10.3. This fixes the tests by running
an actual copy of vault instead of an in-process copy. This has the
added benefit of changing the dependency on vault to just vault/api.
Also update VaultProvider to use similar SetIntermediate validation code
as the ConsulProvider implementation.
* Add build system support for protobuf generation
This is done generically so that we don’t have to keep updating the makefile to add another proto generation.
Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date.
If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild>
Providing the PROTOFILES var will override the default behavior of finding all the .proto files.
* Start adding types to the agent/proto package
These will be needed for some other work and are by no means comprehensive.
* Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store.
* Use protobuf marshalling of raft requests instead of msgpack for protoc generated types.
This does not change any encoding of existing types.
* Removed structs package automatically encoding with protobuf marshalling
Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf`
* Run update-vendor to fixup modules.txt
Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical.
* Rename some things and implement the structs.RPCInfo interface bits
agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth.
* Use the right encoding function.
* Renamed agent/proto package to agent/agentpb to prevent package name conflicts
* Update modules.txt to fix ordering
* Change blockingQuery to take in interfaces for the query options and meta
* Add %T to error output.
* Add/Update some comments
All these changes should have no side-effects or change behavior:
- Use bytes.Buffer's String() instead of a conversion
- Use time.Since and time.Until where fitting
- Drop unnecessary returns and assignment
