[LTP] [RFC PATCH v2 3/4] ima/ima_boot_aggregate: Increase MAX_EVENT_SIZE to 8k

[Petr Vorel]

This is needed as according IMA developers there are BIOS events larger
than 4k [1]. Actual size for TPM 1.2 is undefined, TPM 2.0 specifies:
"For software parsing the event log, the parser can choose an arbitrary
maximum size, but this specification recommends a maximum value for the
TCG_PCR_EVENT2.eventSize field of 1MB." [2].

So hope 8k is enough.
