partitionAuthorizer.config can be nil if it wasn't provided on calls to
newPartitionAuthorizer outside of the ACLResolver. This usage happens
often in tests.
This commit: adds a nil check when the config is going to be used,
updates non-test usage of NewPolicyAuthorizerWithDefaults to pass a
non-nil config, and dettaches setEnterpriseConf from the ACLResolver.
When issuing cross-partition service discovery requests, ACL filtering
often checks for NodeRead privileges. This is because the common return
type is a CheckServiceNode, which contains node data.
As part of removing the legacy ACL system ACL upgrading and the flag for
legacy ACLs is removed from Clients.
This commit also removes the 'acls' serf tag from client nodes. The tag is only ever read
from server nodes.
This commit also introduces a constant for the acl serf tag, to make it easier to track where
it is used.
Remove the error return, so that not handling is not reported as an
error by errcheck. It was returning the error passed as an arg
unmodified so there is no reason to return the same value that was
passed in.
Remove the term upstreams to remove any confusion with the term used in
service mesh.
Remove the AutoDisable field, and replace it with the TTL value, using 0
to indicate the setting is turned off.
Replace "not Before" with "After".
Add some test coverage to show the behaviour is still correct.
This field was never user-configurable. We always overwrote the value with 120s from
NonUserSource. However, we also never copied the value from RuntimeConfig to consul.Config,
So the value in NonUserSource was always ignored, and we used the default value of 30s
set by consul.DefaultConfig.
All of this code is an unnecessary distraction because a user can not actually configure
this value.
This commit removes the fields and uses a constant value instad. Someone attempting to set
acl.disabled_ttl in their config will now get an error about an unknown field, but previously
the value was completely ignored, so the new behaviour seems more correct.
We have to keep this field in the AutoConfig response for backwards compatibility, but the value
will be ignored by the client, so it doesn't really matter what value we set.
This method suffered from similar naming to a couple other methods on Server, and had not great
re-use (2 callers). By copying a few of the lines into one of the callers we can move the
implementation into the second caller.
Once moved, we can see that ResolveTokenAndDefaultMeta is identical in both Client and Server, and
likely should be further refactored, possibly into ACLResolver.
This change is being made to make ACL resolution easier to trace.
ACL filtering only needs an authorizer and a logger. We can decouple filtering from
the ACLResolver by passing in the necessary logger.
This change is being made in preparation for moving the ACLResolver into an acl package
filterACLWithAuthorizer could never return an error. This change moves us a little bit
closer to being able to enable errcheck and catch problems caused by unhandled error
return values.
These functions are moved to the one place they are called to improve code locality.
They are being moved out of agent/consul/acl.go in preparation for moving
ACLResolver to an acl package.
These functions are used in only one place. Move the functions next to their one caller
to improve code locality.
This change is being made in preparation for moving the ACLResolver into an
acl package. The moved functions were previously in the same file as the ACLResolver.
By moving them out of that file we may be able to move the entire file
with fewer modifications.

Previously we were passing an Authorizer that would always allow the
operation, then later checking the authorization using vetServiceTxnOp.
On the surface this seemed strange, but I think it was actually masking
a bug as well. Over time `servicePreApply` was changed to add additional
authorization for `service.Proxy.DestinationServiceName`, but because
we were passing a nil Authorizer, that authorization was not handled on
the txn_endpoint.
`TxnServiceOp.FillAuthzContext` has some special handling in enterprise,
so we need to make sure to continue to use that from the Txn endpoint.
This commit removes the `vetServiceTxnOp` function, and passes in the
`FillAuthzContext` function so that `servicePreApply` can be used by
both the catalog and txn endpoints. This should be much less error prone
and prevent bugs like this in the future.
