Fixups for error messages from ACL Errors (#12620)
Fixups for error messages from ACL Errors

Alter error messages to be more verbose and explanatory, something like:

Permission denied: token with AccessorID '8a2d52a0-6b41-7077-8374-09d4fafa2d30 ' lacks permission 'service:read' on "foobar" on "foobar" in partition "foo" in namespace "bar"

Riddhi Shah 95362cc5ea ACL pkg updates to support Agentless RPCs
For many of the new RPCs that will be added in Consul servers for Agentless work,
the ACL token will need to be authorized for service:write on any service in any namespace in any partition.

The ACL package updates are to make ServiceWriteAny related helpers available on the different authorizers.

Add source of authority annotations to the PermissionDeniedError output. (#12567)
This extends the acl.AllowAuthorizer with source of authority information.

The next step is to unify the AllowAuthorizer and ACLResolveResult structures; that will be done in a separate PR.

Mark Anderson 1a16f7ee70 Refactor to make ACL errors more structured. (#12308)
* First phase of refactoring PermissionDeniedError

Add extended type PermissionDeniedByACLError that captures information
about the accessor, particular permission type and the object and name
of the thing being checked.

It may be worth folding the test and error return into a single helper
function, that can happen at a later date.

Daniel Nephin 5b2e5882b4 acl: move check for Intention.DestinationName into Authorizer
Follow up to https://github.com/hashicorp/consul/pull/10737#discussion_r680134445

Move the check for the Intention.DestinationName into the Authorizer to remove the
need to check what kind of Authorizer is being used.

It sounds like this check is only for legacy ACLs, so is probably just a safeguard
.

agent: protect the ui metrics proxy endpoint behind ACLs (#9099)
This ensures the metrics proxy endpoint is ACL protected behind a
wildcard `service:read` and `node:read` set of rules. For Consul
Enterprise these will need to span all namespaces:

```
service_prefix "" { policy = "read" }
node_prefix ""    { policy = "read" }

namespace_prefix "" {
  service_prefix "" { policy = "read" }
  node_prefix ""    { policy = "read" }
}
```

This PR contains just the backend changes. The frontend changes to
actually pass the consul token header to the proxy through the JS plugin
will come in another PR.

Intentions ACL enforcement updates (#7028)
* 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.

Updates to allow for Namespacing ACL resources in Consul Enterp… (#6675)
Main Changes:

• method signature updates everywhere to account for passing around enterprise meta.
• populate the EnterpriseAuthorizerContext for all ACL related authorizations.
• ACL resource listings now operate like the catalog or kv listings in that the returned entries are filtered down to what the token is allowed to see. With Namespaces its no longer all or nothing.
• Modified the acl.Policy parsing to abstract away basic decoding so that enterprise can do it slightly differently. Also updated method signatures so that when parsing a policy it can take extra ent metadata to use during rules validation and policy creation.

Secondary Changes:

• Moved protobuf encoding functions out of the agentpb package to eliminate circular dependencies.
• Added custom JSON unmarshalers for a few ACL resource types (to support snake case and to get rid of mapstructure)
• AuthMethod validator cache is now an interface as these will be cached per-namespace for Consul Enterprise.
• Added checks for policy/role link existence at the RPC API so we don’t push the request through raft to have it fail internally.
• Forward ACL token delete request to the primary datacenter when the secondary DC doesn’t have the token.
• Added a bunch of ACL test helpers for inserting ACL resource test data.

ACL Authorizer overhaul (#6620)
* ACL Authorizer overhaul

To account for upcoming features every Authorization function can now take an extra *acl.EnterpriseAuthorizerContext. These are unused in OSS and will always be nil.

Additionally the acl package has received some thorough refactoring to enable all of the extra Consul Enterprise specific authorizations including moving sentinel enforcement into the stubbed structs. The Authorizer funcs now return an acl.EnforcementDecision instead of a boolean. This improves the overall interface as it makes multiple Authorizers easily chainable as they now indicate whether they had an authoritative decision or should use some other defaults. A ChainedAuthorizer was added to handle this Authorizer enforcement chain and will never itself return a non-authoritative decision.

* Include stub for extra enterprise rules in the global management policy

* Allow for an upgrade of the global-management policy

New ACLs (#4791)
This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week.
Description

At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers.

On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though.

    Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though.
    All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management.
    Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are:
        A server running the new system must still support other clients using the legacy system.
        A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system.
        The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode.

So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.

Matt Keeler 883c5dd001 Fix ACL enforcement
This creates one function that takes a rule and the required permissions and returns whether it should be allowed and whether to leave the decision to the parent acl.

Then this function is used everywhere. This makes acl enforcement consistent.

There were several places where a default allow policy with explicit deny rules wasnt being handled and several others where it wasn’t using the parent acl appropriately but would lump no policy in with a deny policy. All of that has been fixed.
