* auth/aws: Fix error with empty bound_iam_principal_arn
In cases where there doesn't need to be a bound_iam_principal_arn, i.e.,
either auth_type is ec2 or there are other bindings with the iam
auth_type, but it is specified explicitly anyway, Vault tried to parse
it to resolve to internal unique IDs. This now checks to ensure that
bound_iam_principal_arn is non-empty before attempting to resolve it.
Fixes#3837
* Fix extraneous newline
* 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
Some of the path help documentation was incorrect for auth/aws/role as
behavior changed during PR development and the help wasn't updated. This
fixes incorrect information and makes the path help somewhat more
consistent.
Fixes#3472
A change in copystructure has caused some panics due to the custom copy
function. I'm more nervous about production panics than I am about
keeping some bad code wiping out some existing warnings, so remove the
custom copy function and just allow direct setting of Warnings.
* 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.
