IJ38041: DUPLICATED AND INCORRECT ENTRIES IN NFSV4 ACL WHEN CREATING AND CHANGING PERMISSION'S OF A FILE VIA NFS.

APAR status

• Closed as program error.

Error description

• When a fileset is in chmodAndUpdateAcl permission change
  mode, creating a file with the open() system call under a parent
  directory with inherit entries and changing permission's of the
  newly created file via NFS results in duplicated and incorrect
  entries in the file's NFSv4 ACL.
  

Local fix

• Use chmodAndSetAcl permission change mode for filesets
  and avoid having inherit entries in the parent directory.
  

Problem summary

• When a fileset is in chmodAndUpdateAcl permission change
  mode, creating a file with the open() system call under a parent
  directory with inherit entries and changing permission's of the
  newly created file via NFS results in duplicated and incorrect

  Benefits of the solution:
  The entries in the file's NFSv4 ACL are updated
  correctly and no duplication occurs.
  
  Work Around:
  Use chmodAndSetAcl permission change mode for filesets
  and avoid having inherit entries in the parent directory.
  Problem Trigger:
  Have a fileset in chmodAndUpdateAcl permission change
  mode and a parent directory with inherit entries. Via NFS,
  create a file with the open() system call and change the
  permission's of the file with chmod.
