fmorg-git opened a new pull request, #10108:
URL: https://github.com/apache/ozone/pull/10108

   Please describe your PR in detail:
   * Currently, ACLs used by Ozone and Ranger are not granular enough. For 
example, read on volume, read on bucket, and write on key can be used by either 
`s3:PutObjectTagging` or `s3:DeleteObjectTagging`. Similarly, because 
`s3:PutObject` requires read on volume, read on bucket, and create and write on 
key, someone with `s3:PutObject` access can also call `s3:PutObjectTagging` (as 
an example). To prevent having more access than requested (or different access 
than requested), we need a means of restricting the ACL permissions further by 
S3 actions.
   
   To do this, we introduce an s3Action field in RequestContext so that if 
populated, the RangerOzoneAuthorizer would further restrict the permissions 
according to the S3 action.
   Additionally, the OzoneGrant would contain a Set<String> representing the S3 
actions that are allowed for an inline policy. If all actions are allowed, then 
the Set<String> would be empty (or null).
