In FIPS mode, additional restrictions may apply. If these restrictions
are violated, the kernel will panic(). This patch allows test vectors
for symmetric ciphers to be marked as to be skipped in FIPS mode.
Together with the patch, the XTS test vectors where the AES key is
identical to the tweak key is disabled in FIPS mode. This test vector
violates the FIPS requirement that both keys must be different.

The CPU Jitter RNG provides a source of good entropy by
collecting CPU executing time jitter. The entropy in the CPU
execution time jitter is magnified by the CPU Jitter Random
Number Generator. The CPU Jitter Random Number Generator uses
the CPU execution timing jitter to generate a bit stream
which complies with different statistical measurements that
determine the bit stream is random.
The CPU Jitter Random Number Generator delivers entropy which
follows information theoretical requirements. Based on these
studies and the implementation, the caller can assume that
one bit of data extracted from the CPU Jitter Random Number
Generator holds one bit of entropy.
The CPU Jitter Random Number Generator provides a decentralized
source of entropy, i.e. every caller can operate on a private
state of the entropy pool.
The RNG does not have any dependencies on any other service
in the kernel. The RNG only needs a high-resolution time
stamp.
Further design details, the cryptographic assessment and
large array of test results are documented at
http://www.chronox.de/jent.html.

Patch adds AVX2/x86-64 implementation of Serpent cipher, requiring 16 parallel
blocks for input (256 bytes). Implementation is based on the AVX implementation
and extends to use the 256-bit wide YMM registers. Since serpent does not use
table look-ups, this implementation should be close to two times faster than
the AVX implementation.

Patch adds AVX2/x86-64 implementation of Twofish cipher, requiring 16 parallel

instruction directly from vector registers and thus should be faster than
earlier implementations. Implementation also uses 256-bit wide YMM registers,

A self-test failure in fips mode means a panic. Well, gcm(aes)
self-tests currently fail in fips mode, as gcm is dependent on ghash,
which semi-recently got self-test vectors added, but wasn't marked as a
fips_allowed algorithm. Because of gcm's dependence on what is now seen
as a non-fips_allowed algorithm, its self-tests refuse to run.
Previously, ghash got a pass in fips mode, due to the lack of any test
vectors at all, and thus gcm self-tests were able to run. After this
patch, a 'modprobe tcrypt mode=35' no longer panics in fips mode, and

des3_ede being unable to properly register (see des module init func).
Also, crc32 isn't technically on the fips approved list, but I think

We currently allocate temporary memory that is used for testing
statically. This renders the testing engine non-reentrant. As
algorithms may nest, i.e., one may construct another in order to
carry out a part of its operation, this is unacceptable. For
example, it has been reported that an AEAD implementation allocates
a cipher in its setkey function, which causes it to fail during
testing as the temporary memory is overwritten.
This patch replaces the static memory with dynamically allocated
buffers. We need a maximum of 16 pages so this slightly increases
the chances of an algorithm failing due to memory shortage.
However, as testing usually occurs at registration, this shouldn't
be a big problem.
