            Bug ID: 15196
           Summary: O_APPEND not translated to FILE_APPEND_DATA open flag
           Product: CifsVFS
           Version: 5.x
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: kernel fs
          Assignee: sfrench@samba.org
          Reporter: bjacke@samba.org
        QA Contact: cifs-qa@samba.org
  Target Milestone: ---

While testing the "append data" ACL permission, I wantted to try this out with
cifs vfs against a Windows 10 machine as server.

"tee -a" is using O_APPEND but it looks like cifs vfs is not translating
O_APPEND open calls to SMB's FILE_APPEND_DATA. So files that have "append only"
permission but not "write data" permission will not be "append writable" by
cifs vfs  in cases where they shold.
