Also, patch #2 replaces tpm1_buf code used in security/keys/trusted.c and crypto/asymmertic_keys/asym_tpm.c files to use the common tpm_buf code. Changes in v8: 1. Rebased to latest tpmdd/master. 2. Added Reviewed-by tags. Changes in v7: 1. Rebased to top of tpmdd/master 2. Patch #4: update tpm2 trusted keys code to use tpm_send() instead of tpm_transmit_cmd() which is an internal function. Changes in v6: 1. Switch TPM asymmetric code also to use common tpm_buf code. These changes required patches #1 and #2 update, so I have dropped review tags from those patches. 2. Incorporated miscellaneous comments from Jarkko. Changes in v5: 1. Drop 5/5 patch as its more relavant along with TEE patch-set. 2. Add Reviewed-by tag for patch #2. 3. Fix build failure when "CONFIG_HEADER_TEST" and "CONFIG_KERNEL_HEADER_TEST" config options are enabled. 4. Misc changes to rename files. Changes in v4: 1. Separate patch for export of tpm_buf code to include/linux/tpm.h 2. Change TPM1.x trusted keys code to use common tpm_buf 3. Keep module name as trusted.ko only Changes in v3: Move TPM2 trusted keys code to trusted keys subsystem. Changes in v2: Split trusted keys abstraction patch for ease of review.
