Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity

Pull integrity fixes from Mimi Zohar:
 "A couple of miscellaneous bug fixes for the integrity subsystem:

  IMA:

   - Properly modify the open flags in order to calculate the file hash.

   - On systems requiring the IMA policy to be signed, the policy is
     loaded differently. Don't differentiate between "enforce" and
     either "log" or "fix" modes how the policy is loaded.

  EVM:

   - Two patches to fix an EVM race condition, normally the result of
     attempting to load an unsupported hash algorithm.

   - Use the lockless RCU version for walking an append only list"

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
  evm: Fix a small race in init_desc()
  evm: Fix RCU list related warnings
  ima: Fix return value of ima_write_policy()
  evm: Check also if *tfm is an error pointer in init_desc()
  ima: Set file->f_mode instead of file->f_flags in ima_calc_file_hash()
