Subject: [GIT PULL] tpmdd updates for Linux v5.1
James,
Quite a fat release this time. I'll try to enumerate the highlights.
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.
The following changes since commit 2181e084b26bddca22bc3f23364c15809cfed28b:
