Update the AWS auth backend acceptance tests to account for the new
`iam_tags` field that comes back on responses.
* marked only tests requiring creds as acceptance
Renamed TestBackend_* to TestAcceptanceBackend_* if the test requires
AWS credentials. Otherwise left the name as TestBackend_* and set
`AcceptanceTest: false`.
* ensure generated names aren't too long
IAM roles and users have a 64 character limit, and adding Acceptance
to the test names was putting some over the length limit, so modified
generateUniqueName() to take a max length parameter and added
functions for each type of name generation (user, role, group).
* update genUsername to cap STS usernames at 64 chars
* add changelog
* refactor tests into t.Run block
* patch: remove warningExpected bool and include expected string
* patch: revert sts to cap at 32 chars and add assume_role case in genUsername
* update changelog
* update genUsername to return error if username generated exceeds length limits
* update changelog
* add conditional default username template to provide custom STS usernames
* update changelog
* include test for failing STS length case
* update comments for more clarity
Unlike the other libraries that were migrated, there are no usages of
this lib in any of our plugins, and the only other known usage was in
go-kms-wrapping, which has been updated. Aliasing it like the other libs
would still keep the aws-sdk-go dep in the sdk module because of the
function signatures. So I've simply removed it entirely here.

* Added support for iam_tags for AWS secret roles
This change allows iam_users generated by the secrets engine
to add custom tags in the form of key-value pairs to users
that are created.
Adds debug and warn logging around AWS credential chain generation,
specifically to help users debugging auto-unseal problems on AWS, by
logging which role is being used in the case of a webidentity token.
Adds a deferred call to flush the log output as well, to ensure logs
are output in the event of an initialization failure.

Allows vault roles to be associated with IAM groups in the AWS
secrets engine, since IAM groups are a recommended way to manage
IAM user policies. IAM users generated against a vault role will
be added to the IAM Groups. For a credential type of
`assumed_role` or `federation_token`, the policies sent to the
corresponding AWS call (sts:AssumeRole or sts:GetFederation) will
be the policies from each group in `iam_groups` combined with the
`policy_document` and `policy_arns` parameters.

* secrets/aws: Support permissions boundaries on iam_user creds
This allows configuring Vault to attach a permissions boundary policy to
IAM users that it creates, configured on a per-Vault-role basis.
* Fix indentation of policy in docs
Use spaces instead of tabs
I probably left this cleanup commented out as part of debugging test
errors in #6789 and forgot to uncomment it, so actually cleaning up the
test user.
* secret/aws: Pass policy ARNs to AssumedRole and FederationToken roles
AWS now allows you to pass policy ARNs as well as, and in addition to,
policy documents for AssumeRole and GetFederationToken (see
https://aws.amazon.com/about-aws/whats-new/2019/05/session-permissions/).
Vault already collects policy ARNs for iam_user credential types; now it
will allow policy ARNs for assumed_role and federation_token credential
types and plumb them through to the appropriate AWS calls.
This brings along a minor breaking change. Vault roles of the
federation_token credential type are now required to have either a
policy_document or a policy_arns specified. This was implicit
previously; a missing policy_document would result in a validation error
from the AWS SDK when retrieving credentials. However, it would still
allow creating a role that didn't have a policy_document specified and
then later specifying it, after which retrieving the AWS credentials
would work. Similar workflows in which the Vault role didn't have a
policy_document specified for some period of time, such as deleting the
policy_document and then later adding it back, would also have worked
previously but will now be broken.
The reason for this breaking change is because a credential_type of
federation_token without either a policy_document or policy_arns
specified will return credentials that have equivalent permissions to
the credentials the Vault server itself is using. This is quite
dangerous (e.g., it could allow Vault clients access to retrieve
credentials that could modify Vault's underlying storage) and so should
be discouraged. This scenario is still possible when passing in an
appropriate policy_document or policy_arns parameter, but clients should
be explicitly aware of what they are doing and opt in to it by passing
in the appropriate role parameters.
* Error out on dangerous federation token retrieval
The AWS secrets role code now disallows creation of a dangerous role
configuration; however, pre-existing roles could have existed that would
trigger this now-dangerous code path, so also adding a check for this
configuration at credential retrieval time.
* Run makefmt
* Fix tests
* Fix comments/docs
This refactors role validation for the AWS secrets engine to be in a
separate method. Previously, all validation was interspersed with the
parsing of parameters when creating/updating a role, which led to a high
degree of complexity. Now, all validation is centralized which makes it
easier to understand and also easier to test (and so a number of test
cases have been added).
The result will still pass gofmtcheck and won't trigger additional
changes if someone isn't using goimports, but it will avoid the
piecemeal imports changes we've been seeing.
* Added role-option max_sts_ttl to cap TTL for AWS STS credentials.
* Allow for setting max_sts_ttl to 0 after it has been set already.
* Fixed message in error response for default_sts_ttl > max_sts_ttl.
* Allow specifying role-default TTLs in AWS secret engine
* Add an acceptance test
* Add docs for AWS secret role-default TTLs
* Rename default_ttl to default_sts_ttl
* Return default_ttl as int64 instead of time.Duration
* Fix broken tests
The merge of #5383 broke the tests due to some changes in the test style
that didn't actually cause a git merge conflict. This updates the tests
to the new style.
* logical/aws: Harden WAL entry creation
If AWS IAM user creation failed in any way, the WAL corresponding to the
IAM user would get left around and Vault would try to roll it back.
However, because the user never existed, the rollback failed. Thus, the
WAL would essentially get "stuck" and Vault would continually attempt to
roll it back, failing every time. A similar situation could arise if the
IAM user that Vault created got deleted out of band, or if Vault deleted
it but was unable to write the lease revocation back to storage (e.g., a
storage failure).
This attempts to harden it in two ways. One is by deleting the WAL log
entry if the IAM user creation fails. However, the WAL deletion could
still fail, and this wouldn't help where the user is deleted out of
band, so second, consider the user rolled back if the user just doesn't
exist, under certain circumstances.
Fixes#5190
* Fix segfault in expiration unit tests
TestExpiration_Tidy was passing in a leaseEntry that had a nil Secret,
which then caused a segfault as the changes to revokeEntry didn't check
whether Secret was nil; this is probably unlikely to occur in real life,
but good to be extra cautious.
* Fix potential segfault
Missed the else...
* Respond to PR feedback
* Add AWS Secret Engine Root Credential Rotation
This allows the AWS Secret Engine to rotate its credentials used to
access AWS. This will only work when the AWS Secret Engine has been
provided explicit IAM credentials via the config/root endpoint, and
further, when the IAM credentials provided are the only access key on
the IAM user associated wtih the access key (because AWS allows a
maximum of 2 access keys per user).
Fixes#4385
* Add test for AWS root credential rotation
Also fix a typo in the root credential rotation code
* Add docs for AWS root rotation
* Add locks around reading and writing config/root
And wire the backend up in a bunch of places so the config can get the
lock
* Respond to PR feedback
* Fix casing in error messages
* Fix merge errors
* Fix locking bugs
