Subject: [PATCH] FIPS: introduce HMAC based library integrity check
When in FIPS mode, perform an integrity check on libica.so by calculating
an HMAC from the file contents using a static HMAC key, and comparing it
to a pre-calculated HMAC in a separate file. The HMAC key and HMAC file
may be provided by a Distributor when building the packet. The test
succeeds if the HMAC file is not present.
