Title:
  Creation of IMA file hashes fails when appraisal is enabled

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Xenial:
  Fix Released

Bug description:
  == SRU Justification ==
  On a system that has IMA appraisal enabled it is impossible to create
  security.ima extended attribute files that contain IMA hash.  This is
  due to mainline commit c68ed80c97d, which prevents writing file hashes as
  security.ima xattrs.

  This bug is fixed by reverting commit c68ed80c97d, which is done by
  mainline commit f5acb3dcba1f as of v4.10-rc1.

  == Fix ==
  f5acb3dcba1f ("Revert "ima: limit file hash setting by user to fix and log 
modes"")

  == Regression Potential ==
  Low.  This revert happend in v4.10-rc1.  It has been in Artful and
  Bionic for a while without any reported issues.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.


  == Original Bug Description ==
  On a system that has IMA appraisal enabled it is impossible to create
  security.ima extended attribute files that contain IMA hash.

  For instance, consider the following use case:

  1) extract application files to a staging area as non root user
  2) verify that installation is correct
  3) create IMA extended attributes for the installed files
  4) move the files to their destination
  5) change the files ownership to root

  With kernel 4.4.x step 3 will fail.

  The issues is fixed in upstream kernels by the following commit [1]:

  commit f5acb3dcba1ffb7f0b8cbb9dba61500eea5d610b
  Author: Mimi Zohar <zo...@linux.vnet.ibm.com>
  Date:   Wed Nov 2 09:14:16 2016 -0400

      Revert "ima: limit file hash setting by user to fix and log modes"
