This patch dynamically allocates the array of tpm_digest structures in ima_alloc_init_template() and ima_restore_template_data(). The size of the array is equal to the number of PCR banks plus ima_extra_slots, to make room for SHA1 and the IMA default hash algorithm, when PCR banks with those algorithms are not allocated. Calculating the SHA1 digest is mandatory, as SHA1 still remains the default hash algorithm for the measurement list. When IMA will support the Crypto Agile format, remaining digests will be also provided. The position in the measurement entry array of the SHA1 digest is stored in the ima_sha1_idx global variable and is determined at IMA initialization time.
