Linus Torvalds 5af7f11588 Merge branch 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull tpm updates from James Morris:

 - Clean up the transmission flow

   Cleaned up the whole transmission flow. Locking of the chip is now
   done in the level of tpm_try_get_ops() and tpm_put_ops() instead
   taking the chip lock inside tpm_transmit(). The nested calls inside
   tpm_transmit(), used with the resource manager, have been refactored
   out.

   Should make easier to perform more complex transactions with the TPM
   without making the subsystem a bigger mess (e.g. encrypted channel
   patches by James Bottomley).

 - PPI 1.3 support

   TPM PPI 1.3 introduces an additional optional command parameter that
   may be needed for some commands. Display the parameter if the command
   requires such a parameter. Only command 23 (SetPCRBanks) needs one.

   The PPI request file will show output like this then:

      # echo "23 16" > request
      # cat request
      23 16

      # echo "5" > request
      # cat request
      5

 - Extend all PCR banks in IMA

   Instead of static PCR banks array, the array of available PCR banks
   is now allocated dynamically. The digests sizes are determined
   dynamically using a probe PCR read without relying crypto's static
   list of hash algorithms.

   This should finally make sealing of measurements in IMA safe and
   secure.

 - TPM 2.0 selftests

   Added a test suite to tools/testing/selftests/tpm2 previously outside
   of the kernel tree: https://github.com/jsakkine-intel/tpm2-scripts
