ima: provide support for arbitrary hash algorithms
In preparation of supporting more hash algorithms with larger hash sizes needed for signature verification, this patch replaces the 20 byte sized digest, with a more flexible structure. The new structure includes the hash algorithm, digest size, and digest. Changelog: - recalculate filedata hash for the measurement list, if the signature hash digest size is greater than 20 bytes. - use generic HASH_ALGO_ - make ima_calc_file_hash static - scripts lindent and checkpatch fixes Signed-off-by: NDmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: NMimi Zohar <zohar@linux.vnet.ibm.com>
