tpm: Fix the type of the return value in calc_tpm2_event_size()

2019-04-08T22:58:54+00:00

calc_tpm2_event_size() has an invalid signature because it returns a 'size_t' where as its signature says that it returns 'int'.

tpm: add _head suffix to tcg_efi_specid_event and tcg_pcr_event2

2019-02-13T07:47:01+00:00

TCG defines two structures, TCG_EfiSpecIDEventStruct and TCG_PCR_EVENT2, which contain variable-sized arrays in the middle of the definition. Since these structures are not suitable for type casting, this patch removes structure members after the variable-sized arrays and adds the _head suffix to the structure name, to indicate that the renamed structures do not contain all fields defined by TCG. Lastly, given that variable-sized arrays are now in the last position, and given that the size of the arrays cannot be determined in advance, this patch also sets the size of those arrays to zero and removes the definition of TPM2_ACTIVE_PCR_BANKS.

tpm: Fix off-by-one when reading binary_bios_measurements

tpm: Simplify the measurements loop

2019-02-13T07:47:00+00:00

The responsibility of tpm1_bios_measurements_start() is to walk over the first *pos measurements, ensuring the skipped and to-be-read measurements are not out-of-boundary. This commit simplifies the loop by employing a do-while loop with the necessary sanity check. Signed-off-by: Jia Zhang Reviewd-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen
