James Bottomley eb24c9788c tpm: disable the TPM if NULL name changes ... Update tpm2_load_context() to return -EINVAL on integrity failures and use this as a signal when loading the NULL context that something might be wrong. If the signal fails, check the name of the NULL primary against the one stored in the chip data and if there is a mismatch disable the TPM because it is likely to have suffered a reset attack.
