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 * 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (37 commits) tpm/ppi: Enable submission of optional command parameter for PPI 1.3 tpm/ppi: Possibly show command parameter if TPM PPI 1.3 is used tpm/ppi: Display up to 101 operations as define for version 1.3 tpm/ppi: rename TPM_PPI_REVISION_ID to TPM_PPI_REVISION_ID_1 tpm/ppi: pass function revision ID to tpm_eval_dsm() tpm: pass an array of tpm_extend_digest structures to tpm_pcr_extend() KEYS: trusted: explicitly use tpm_chip structure from tpm_default_chip() tpm: move tpm_chip definition to include/linux/tpm.h tpm: retrieve digest size of unknown algorithms with PCR read tpm: rename and export tpm2_digest and tpm2_algorithms tpm: dynamically allocate the allocated_banks array tpm: remove @flags from tpm_transmit() tpm: take TPM chip power gating out of tpm_transmit() tpm: introduce tpm_chip_start() and tpm_chip_stop() tpm: remove TPM_TRANSMIT_UNLOCKED flag tpm: use tpm_try_get_ops() in tpm-sysfs.c. tpm: remove @space from tpm_transmit() tpm: move TPM space code out of tpm_transmit() tpm: move tpm_validate_commmand() to tpm2-space.c tpm: clean up tpm_try_transmit() error handling flow ...
