* Use a role cache to avoid separate locking paths
Due to the various locked/nonlocked paths we had a case where we weren't
always checking for secondary status before trying to upgrade. This
broadly simplifies things by using a cache to store the current role
values (avoiding a lot of storage hits) and updating the cache on any
write, delete, or invalidation.
Update AWS Auth backend to use TypeHeader for iam request headers
- Remove parseIamRequestHeaders function and test, no longer needed with new TypeHeader
- Update AWS auth login docs
The parseIamArn method was making assumptions about the input arn being
properly formatted and of a certain type. If users tried to pass a
bound_iam_principal_arn that was malformed (or was the ARN of the root
user), it would cause a panic. parseIamArn now explicitly checks the
assumptions it's making and tests are added to ensure it properly errors
out (rather than panic'ing) on malformed input.
* Rename builtin/credential/aws-ec2 to aws
The aws-ec2 authentication backend is being expanded and will become the
generic aws backend. This is a small rename commit to keep the commit
history clean.
* Expand aws-ec2 backend to more generic aws
This adds the ability to authenticate arbitrary AWS IAM principals using
AWS's sts:GetCallerIdentity method. The AWS-EC2 auth backend is being to
just AWS with the expansion.
* Add missing aws auth handler to CLI
This was omitted from the previous commit
* aws auth backend general variable name cleanup
Also fixed a bug where allowed auth types weren't being checked upon
login, and added tests for it.
* Update docs for the aws auth backend
* Refactor aws bind validation
* Fix env var override in aws backend test
Intent is to override the AWS environment variables with the TEST_*
versions if they are set, but the reverse was happening.
* Update docs on use of IAM authentication profile
AWS now allows you to change the instance profile of a running instance,
so the use case of "a long-lived instance that's not in an instance
profile" no longer means you have to use the the EC2 auth method. You
can now just change the instance profile on the fly.
* Fix typo in aws auth cli help
* Respond to PR feedback
* More PR feedback
* Respond to additional PR feedback
* Address more feedback on aws auth PR
* Make aws auth_type immutable per role
* Address more aws auth PR feedback
* Address more iam auth PR feedback
* Rename aws-ec2.html.md to aws.html.md
Per PR feedback, to go along with new backend name.
* Add MountType to logical.Request
* Make default aws auth_type dependent upon MountType
When MountType is aws-ec2, default to ec2 auth_type for backwards
compatibility with legacy roles. Otherwise, default to iam.
* Pass MountPoint and MountType back up to the core
Previously the request router reset the MountPoint and MountType back to
the empty string before returning to the core. This ensures they get set
back to the correct values.
