From: James Morris Date: Wed, 13 Feb 2019 20:01:00 +0000 (-0800) Subject: Merge tag 'tpmdd-next-20190213' of git://git.infradead.org/users/jjs/linux-tpmdd... X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5da10728037afea6743b76afddfdc9950cd711b3;p=linux.git Merge tag 'tpmdd-next-20190213' of git://git.infradead.org/users/jjs/linux-tpmdd into next-tpm tpmdd updates for Linux v5.1 From: Jarkko Sakkinen 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. --- 5da10728037afea6743b76afddfdc9950cd711b3
