This patch-set is an outcome of discussion here [1]. It has evolved very much since v1 to create, consolidate and generalize trusted keys subsystem. This framework has been tested with trusted keys support provided via TEE but I wasn't able to test it with a TPM device as I don't possess one. It would be really helpful if others could test this patch-set using a TPM device. [1] https://www.mail-archive.com/linux-doc@xxxxxxxxxxxxxxx/msg30591.html 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.
