* Update aws auth docs with new semantics
Moving away from implicitly globbed bound_iam_role_arn and
bound_iam_instance_profile_arn variables to make them explicit
* Refactor tests to reduce duplication
auth/aws EC2 login tests had the same flow duplicated a few times, so
refactoring to reduce duplication
* Add tests for aws auth explicit wildcard constraints
* Remove implicit prefix matching from AWS auth backend
In the aws auth backend, bound_iam_role_arn and
bound_iam_instance_profile_arn were ALWAYS prefix matched, and there was
no way to opt out of this implicit prefix matching. This now makes the
implicit prefix matching an explicit opt-in feature by requiring users
to specify a * at the end of an ARN if they want the prefix matching.
* auth/aws: Allow binding by EC2 instance IDs
This allows specifying a list of EC2 instance IDs that are allowed to
bind to the role. To keep style formatting with the other bindings, this
is still called bound_ec2_instance_id rather than bound_ec2_instance_ids
as I intend to convert the other bindings to accept lists as well (where
it makes sense) and keeping them with singular names would be the
easiest for backwards compatibility.
Partially fixes#3797
* auth/aws: Allow lists in binds
In the aws auth method, allow a number of binds to take in lists
instead of a single string value. The intended semantic is that, for
each bind type set, clients must match at least one of each of the bind
types set in order to authenticate.
* Don't call LeaseExtend on login renewal paths when period is provided
* WIP tests
* NoopBackend accept backend ttl values
* Test period value on credentials backend
* Use t.Fatalf instead
* Remove mockCoreExpiration
* Add login renewal test for approle backend
* Add resp.Auth.Period check on aws and cert backend tests
* Pass in approle's period via role's period
* Correctly set period in valid-role's role
* Add period renewal test using TestCluster and approle backend
* Check for ttl values after renewals on test
* Start work on passing context to backends
* More work on passing context
* Unindent logical system
* Unindent token store
* Unindent passthrough
* Unindent cubbyhole
* Fix tests
* use requestContext in rollback and expiration managers
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.
Previously, the renew method would ALWAYS check to ensure the
authenticated IAM principal ARN matched the bound ARN. However, there
is a valid use case in which no bound_iam_principal_arn is specified and
all bindings are done through inferencing. When a role is configured
like this, clients won't be able to renew their token because of the
check.
This now checks to ensure that the bound_iam_principal_arn is not empty
before requriing that it match the originally authenticated client.
Fixes#2781
* 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.
