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

Pull IMA updates from Mimi Zohar:
 "Two new features - measuring certificates and querying IMA for a file
  hash - and three bug fixes:

   - Measuring certificates is like the rest of IMA, based on policy,
     but requires loading a custom policy. Certificates loaded onto a
     keyring, for example during early boot, before a custom policy has
     been loaded, are queued and only processed after loading the custom
     policy.

   - IMA calculates and caches files hashes. Other kernel subsystems,
     and possibly kernel modules, are interested in accessing these
     cached file hashes.

  The bug fixes prevent classifying a file short read (e.g. shutdown) as
  an invalid file signature, add a missing blank when displaying the
  securityfs policy rules containing LSM labels, and, lastly, fix the
  handling of the IMA policy information for unknown LSM labels"

  IMA: pre-allocate buffer to hold keyrings string
  ima: ima/lsm policy rule loading logic bug fixes
  ima: add the ability to query the cached hash of a given file
  ima: Add a space after printing LSM rules for readability
  IMA: fix measuring asymmetric keys Kconfig
  IMA: Read keyrings= option from the IMA policy
  IMA: Add support to limit measuring keys
  KEYS: Call the IMA hook to measure keys
  IMA: Define an IMA hook to measure keys
  IMA: Add KEY_CHECK func to measure keys
  IMA: Check IMA policy flag
  ima: avoid appraise error for hash calc interrupt
