This allows batch replication to basically do not
attempt to copy objects that do not have read quorum.
This PR also allows walk() to provide custom
values for quorum under batch replication, and
key rotation.
To ensure that policy mappings are current for service accounts
belonging to (non-derived) STS accounts (like an LDAP user's service
account) we periodically reload such mappings.
This is primarily to handle a case where a policy mapping update
notification is missed by a minio node. Such a node would continue to
have the stale mapping in memory because STS creds/mappings were never
periodically scanned from storage.
This helps reduce disk operations as these periodic routines would not
run concurrently any more.
Also add expired STS purging periodic operation: Since we do not scan
the on-disk STS credentials (and instead only load them on-demand) a
separate routine is needed to purge expired credentials from storage.
Currently this runs about a quarter as often as IAM refresh.
Also fix a bug where with etcd, STS accounts could get loaded into the
iamUsersMap instead of the iamSTSAccountsMap.
In situations with large number of STS credentials on disk, IAM load
time is high. To mitigate this, STS accounts will now be loaded into
memory only on demand - i.e. when the credential is used.
In each IAM cache (re)load we skip loading STS credentials and STS
policy mappings into memory. Since STS accounts only expire and cannot
be deleted, there is no risk of invalid credentials being reused,
because credential validity is checked when it is used.
Sometimes IAM fails to load certain items, which could be a user,
a service account or a policy but with not enough information for
us to debug.
This commit will create a more descriptive error to make it easier to
debug in such situations.

Update on-disk storage format for users system (#7949)
```
Bonus: fixes a bug when etcd keys were being re-encrypted.
listConfigItems creates a goroutine but sometimes callers will
exit without properly asking listAllIAMConfigItems() to stop sending
results, hence a goroutine leak.
Create a new context and cancel it for each listAllIAMConfigItems
call.
- This introduces a new admin API with a query parameter (v=2) to return a
response with the timestamps
- Older API still works for compatibility/smooth transition in console
This reverts commit 091a7ae359.
- Ensure all actions accessing storage lock properly.
- Behavior change: policies can be deleted only when they
are not associated with any active credentials.
Also adds fix for accidental canned policy removal that was present in the
reverted version of the change.
- Ensure all actions accessing storage lock properly.
- Behavior change: policies can be deleted only when they
are not associated with any active credentials.
IAMSys is a higher-level object, that should not be called by the lower-level
storage API interface for IAM. This is to prepare for further improvements in
IAM code.
Additional support for vendor-specific admin API
integrations for OpenID, to ensure validity of
credentials on MinIO.
Every 5minutes check for validity of credentials
on MinIO with vendor specific IDP.
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
This commit changes the config/IAM encryption
process. Instead of encrypting config data
(users, policies etc.) with the root credentials
MinIO now encrypts this data with a KMS - if configured.
Therefore, this PR moves the MinIO-KMS configuration (via
env. variables) to a "top-level" configuration.
The KMS configuration cannot be stored in the config file
since it is used to decrypt the config file in the first
place.
As a consequence, this commit also removes support for
Hashicorp Vault - which has been deprecated anyway.

under large deployments loading credentials might be
time consuming, while this is okay and we will not
respond quickly for `mc admin user list` like queries
but it is possible to support `mc admin user info`
just like how we handle authentication by fetching
the user directly from persistent store.
additionally support service accounts properly,
reloaded from etcd during watch() - this was missing
This PR is also half way remedy for #11305
Bonus fixes, remove package retry it is harder to get it
right, also manage context remove it such that we don't have
to rely on it anymore instead use a simple Jitter retry.
Allow requests to come in for users as soon as object
layer and config are initialized, this allows users
to be authenticated sooner and would succeed automatically
on servers which are yet to fully initialize.
Bonus also fix a bug where we did not purge relevant
service accounts generated by rotating credentials
appropriately, service accounts should become invalid
as soon as its corresponding parent user becomes invalid.
Since service account themselves carry parent claim always
we would never reach this problem, as the access get
rejected at IAM policy layer.
This PR adds support for healing older
content i.e from 2yrs, 1yr. Also handles
other situations where our config was
not encrypted yet.
This PR also ensures that our Listing
is consistent and quorum friendly,
such that we don't list partial objects
gorilla/mux broke their recent release 1.7.4 which we
upgraded to, we need the current workaround to ensure
that our regex matches appropriately.
An upstream PR is sent, we should remove the
workaround once we have a new release.
