This PR changes the handling of bucket deletes for site
replicated setups to hold on to deleted bucket state until
it syncs to all the clusters participating in site replication.
currently, we allowed buckets to be listed from the
API call if and when the user has ListObject()
permission at the global level, this is okay to be
extended to GetBucketLocation() as well since
GetBucketLocation() is a "read" call and allowing "reads"
on a bucket has an implicit assumption that ListBuckets()
should be allowed.
This makes discoverability of access for read-only users
becomes easier or users with specific restrictions on their
policies.
this PR introduces a few changes such as
- sessionPolicyName is not reused in an extracted manner
to apply policies for incoming authenticated calls,
instead uses a different key to designate this
information for the callers.
- this differentiation is needed to ensure that service
account updates do not accidentally store JSON representation
instead of base64 equivalent on the disk.
- relax requirements for Deleting a service account, allow
deleting a service account that might be unreadable, i.e
a situation where the user might have removed session policy
which now carries a JSON representation, making it unparsable.
- introduce some constants to reuse instead of strings.
fixes#14784
space characters at the beginning or at the end can lead to
confusion under various UI elements in differentiating the
actual name of "policy, user or group" - to avoid this behavior
this PR onwards we shall reject such inputs for newer entries.
existing saved entries will behave as is and are going to be
operable until they are removed/renamed to something more
meaningful.
heal bucket metadata and IAM entries for
sites participating in site replication from
the site with the most updated entry.

In previous releases, mc admin user list would return the list of users
that have policies mapped in IAM database. However, this was removed but
this commit will bring it back until we revamp this.
- Site replication was missing replicating users,
groups when an empty site was added.
- Add site replication for groups and users when they
are disabled and enabled.
- Add support for replicating bucket quota config.
- This allows site-replication to be configured when using OpenID or the
internal IDentity Provider.
- Internal IDP IAM users and groups will now be replicated to all members of the
set of replicated sites.
- When using OpenID as the external identity provider, STS and service accounts
are replicated.
- Currently this change dis-allows root service accounts from being
replicated (TODO: discuss security implications).
The AddUser() API endpoint was accepting a policy field.
This API is used to update a user's secret key and account
status, and allows a regular user to update their own secret key.
The policy update is also applied though does not appear to
be used by any existing client-side functionality.
This fix changes the accepted request body type and removes
the ability to apply policy changes as that is possible via the
policy set API.
NOTE: Changing passwords can be disabled as a workaround
for this issue by adding an explicit "Deny" rule to disable the API
for users.
- When using MinIO's internal IDP, STS credential permissions did not check the
groups of a user.
- Also fix bug in policy checking in AccountInfo 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
- allow any regular user to change their own password
- allow STS credentials to create users if permissions allow
Bonus: do not allow changes to sts/service account credentials (via add user API)
- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

creating service accounts is implicitly enabled
for all users, this PR however adds support to
reject creating service accounts, with an explicit
"Deny" policy.
As we use etcd's watch interface, we do not need the
network notifications as they are no-ops anyway.
Bonus: Remove globalEtcdClient global usage in IAM
This change allows a set of MinIO sites (clusters) to be configured
for mutual replication of all buckets (including bucket policies, tags,
object-lock configuration and bucket encryption), IAM policies,
LDAP service accounts and LDAP STS accounts.
