This reverts commit 9b9f9296a7b73fbafe0a0a6f2494eaadd97f9f73 as
all in-kernel implementations of GCM have been converted to the
new AEAD interface, meaning that they should now pass the updated

Because the old rfc4543 implementation always injected an IV into

while it is converted over to the new AEAD interface.

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.

The DRBG test code implements the CAVS test approach.

As discussed for the test vectors, all DRBG types are covered with
testing. However, not every backend cipher is covered with testing. To
prevent the testmgr from logging missing testing, the NULL test is
registered for all backend ciphers not covered with specific test cases.

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

Converting this implementation to use the same method as in twofish/AVX for

correctness of the transform can be checked with the command
	modprobe tcrypt mode=47
The speed of the transform can be evaluated with the command
	modprobe tcrypt mode=320

Set the cpu frequency to constant and turn turbo off when running the
speed test so the frequency governor will not tweak the frequency and
affects the measurements.

f3f935a76a crypto: camellia - add AVX2/AES-NI/x86_64 assembler implementation of camellia cipher
Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring
32 parallel blocks for input (512 bytes). Compared to AVX implementation, this
version is extended to use the 256-bit wide YMM registers. For AES-NI
instructions data is split to two 128-bit registers and merged afterwards.
Even with this additional handling, performance should be higher compared
to the AES-NI/AVX implementation.

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.

107778b592 crypto: twofish - add x86_64/avx assembler implementation
This patch adds a x86_64/avx assembler implementation of the Twofish block
cipher. The implementation processes eight blocks in parallel (two 4 block
chunk AVX operations). The table-lookups are done in general-purpose registers.
For small blocksizes the 3way-parallel functions from the twofish-x86_64-3way
module are called. A good performance increase is provided for blocksizes
greater or equal to 128B.

Patch has been tested with tcrypt and automated filesystem tests.

18c0ebd2d8 crypto: testmgr - mark ghash as fips_allowed
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
successful self-test of gcm(aes) is reported.

a3bef3a31a crypto: testmgr - Skip algs not flagged fips_allowed in fips mode
Because all fips-allowed algorithms must be self-tested before they
can be used, they will all have entries in testmgr.c's alg_test_descs[].
Skip self-tests for any algs not flagged as fips_approved and return
-EINVAL when in fips mode.

a1915d51e8 crypto: testmgr - Mark algs allowed in fips mode
Set the fips_allowed flag in testmgr.c's alg_test_descs[] for algs
that are allowed to be used when in fips mode.

One caveat: des isn't actually allowed anymore, but des (and thus also
ecb(des)) has to be permitted, because disallowing them results in
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
it gets used in various places that necessitate it being allowed.

This list is based on
http://csrc.nist.gov/groups/STM/cavp/index.html

Important note: allowed/approved here does NOT mean "validated", just
that its an alg that *could* be validated.
