This patch set does not yet include support for isolating policy and HMAC sessions but it is trivial to add once the basic approach is settled (and that's why I created an RFC patch set). v2: Changed to James' proposal of API. I did not make any other changes except split core TPM space code its own patch because I want to find consensus on the API before polishing the corners. Thus, this version also carries the RFC tag. I have not yet locked in my standpoint whether ioctl or a device file is a better deal. James Bottomley (2): tpm: split out tpm-dev.c into tpm-dev.c and tpm-common-dev.c tpm2: expose resource manager via a device link /dev/tpms Jarkko Sakkinen (3): tpm: validate TPM 2.0 commands tpm: export tpm2_flush_context_cmd tpm: infrastructure for TPM spaces drivers/char/tpm/Makefile | 2 +- drivers/char/tpm/tpm-chip.c | 61 +++++++- drivers/char/tpm/tpm-dev-common.c | 145 +++++++++++++++++++ drivers/char/tpm/tpm-dev.c | 141 ++---------------- drivers/char/tpm/tpm-dev.h | 27 ++++ drivers/char/tpm/tpm-interface.c | 106 ++++++++++---- drivers/char/tpm/tpm-sysfs.c | 2 +- drivers/char/tpm/tpm.h | 57 ++++++-- drivers/char/tpm/tpm2-cmd.c | 144 ++++++++++++------ drivers/char/tpm/tpm2-space.c | 298 ++++++++++++++++++++++++++++++++++++++ drivers/char/tpm/tpms-dev.c | 57 ++++++++ 11 files changed, 826 insertions(+), 214 deletions(-) create mode 100644 drivers/char/tpm/tpm-dev-common.c create mode 100644 drivers/char/tpm/tpm-dev.h create mode 100644 drivers/char/tpm/tpm2-space.c create mode 100644 drivers/char/tpm/tpms-dev.c -- 2.9.3
