84cba178a3 crypto: testmgr - don't copy from source IV too much
While the destination buffer 'iv' is MAX_IVLEN size,
the source 'template[i].iv' could be smaller, thus
memcpy may read read invalid memory.
Use crypto_skcipher_ivsize() to get real ivsize
and pass it to memcpy.

bb5530e408 crypto: jitterentropy - add jitterentropy RNG
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.

8a45ac12ec crypto: testmgr - don't use interruptible wait in tests
tcrypt/testmgr uses wait_for_completion_interruptible() everywhere when
it waits for a request to be completed.  If it's interrupted, then the
test is aborted and the request is freed.

However, if any of these calls actually do get interrupted, the result
will likely be a kernel crash, when the driver handles the now-freed
request.  Use wait_for_completion() instead.

All currently implemented DRBG types and backend ciphers are defined
in SP800-90A. Therefore, the fips_allowed flag is set for all.

3a338f20c3 crypto: testmgr - test skciphers with unaligned buffers
This patch adds unaligned buffer tests for blkciphers.

The first new test is with one byte offset and the second test checks if
cra_alignmask for driver is big enough; for example, for testing a case
where cra_alignmask is set to 7, but driver really needs buffers to be
aligned to 16 bytes.
