Security issues fixed:
CVE-2019-12904: The C implementation of AES is vulnerable to a
 flush-and-reload side-channel attack because physical addresses are
 available to other processes. (The C implementation is used on platforms
 where an assembly-language implementation is unavailable.) (bsc#1138939)

Other bugfixes:
Don't run full FIPS self-tests from constructor (bsc#1097073)

Skip all the self-tests except for binary integrity when called from the
 constructor (bsc#1097073)

Enforce the minimal RSA keygen size in fips mode (bsc#1125740)

avoid executing some tests twice.

Fixed a race condition in initialization.

Fixed env-script-interpreter in cavs_driver.pl

Fixed redundant fips tests in some situations causing failure to boot in
 fips mode. (bsc#1097073)

This helps during booting of the system in FIPS mode with insufficient entropy.");
