[tpmdd-devel] [PATCH v9 2/2] tpm: add securityfs support for TPM 2.0 firmware event log

Unlike the device driver support for TPM 1.2, the TPM 2.0 does not support the securityfs pseudo files for displaying the firmware event log. This patch enables support for providing the TPM 2.0 event log in binary form. TPM 2.0 event log supports a crypto agile format that records multiple

[tpmdd-devel] [PATCH v9 1/2] tpm: enhance read_log_of() to support Physical TPM event log

Physical TPMs use Open Firmware Device Tree bindings that are similar to the IBM Power virtual TPM to support event log. However, these properties store the values in different endianness for Physical and Virtual TPM. This patch fixes the endianness issue by doing appropriate conversion based on

[tpmdd-devel] [PATCH v9 0/2] securityfs support for TPM 2.0 firmware event log

The TPM device driver defines ascii and binary methods for displaying the TPM 1.2 event log via securityfs files, which are needed for validating a TPM quote. The device driver for TPM 2.0 does not have similar support for displaying the TPM 2.0 event log. This patch set adds the support for

[tpmdd-devel] [PATCH RFC v4 3/5] tpm: infrastructure for TPM spaces

Added ability to tpm_transmit() to supply a TPM space that contains mapping from virtual handles to physical handles and backing storage for swapping transient objects. TPM space is isolated from other users of the TPM. Signed-off-by: Jarkko Sakkinen ---

[tpmdd-devel] [PATCH RFC v4 1/5] tpm: validate TPM 2.0 commands

Check for every TPM 2.0 command that the command code is supported and the command buffer has at least the length that can contain the header and the handle area. Signed-off-by: Jarkko Sakkinen --- drivers/char/tpm/tpm-interface.c | 37 +-

[tpmdd-devel] [PATCH RFC v4 0/5] RFC: in-kernel resource manager

This patch set adds support for TPM spaces that provide a context for isolating and swapping transient objects. The content does not yet include support for policy and HMAC sessions. There's a test script for trying out TPM spaces in git://git.infradead.org/users/jjs/tpm2-scripts.git A simple
