The CTR DRBG derives its random data from the CTR that is encrypted with
AES.

This patch now changes the CTR DRBG implementation such that the
CTR AES mode is employed. This allows the use of steamlined CTR AES
implementation such as ctr-aes-aesni.

Unfortunately there are the following subtile changes we need to apply
when using the CTR AES mode:

- the CTR mode increments the counter after the cipher operation, but
  the CTR DRBG requires the increment before the cipher op. Hence, the
  crypto_inc is applied to the counter (drbg->V) once it is
  recalculated.

- the CTR mode wants to encrypt data, but the CTR DRBG is interested in
  the encrypted counter only. The full CTR mode is the XOR of the
  encrypted counter with the plaintext data. To access the encrypted
  counter, the patch uses a NULL data vector as plaintext to be
  "encrypted".

Now block cipher engines need to implement and maintain their own queue/thread
for processing requests, moreover currently helpers provided for only the queue
itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they
don't help with the mechanics of driving the hardware (things like running the
request immediately, DMA map it or providing a thread to process the queue in)
even though a lot of that code really shouldn't vary that much from device to
device.

Thus this patch provides a mechanism for pushing requests to the hardware
as it becomes free that drivers could use. And this framework is patterned
on the SPI code and has worked out well there.

When building the jitterentropy driver by itself, we get a link error
when CRYPTO_RNG is not enabled as well:

crypto/built-in.o: In function `jent_mod_exit':

This adds a 'select CRYPTO_RNG' to CRYPTO_JITTERENTROPY to ensure the API
is always there when it's used, not just when DRBG is also enabled.
CRYPTO_DRBG would set it implicitly through CRYPTO_JITTERENTROPY now,
but this leaves it in place to make it explicit what the driver does.

Implements an x86_64 assembler driver for the Poly1305 authenticator. This
single block variant holds the 130-bit integer in 5 32-bit words, but uses
SSE to do two multiplications/additions in parallel.

When calling updates with small blocks, the overhead for kernel_fpu_begin/
kernel_fpu_end() negates the perfmance gain. We therefore use the
poly1305-generic fallback for small updates.

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.

This patch adds a new AEAD IV generator echainiv.  It is intended
to replace the existing skcipher IV generator eseqiv.

If the underlying AEAD algorithm is using the old AEAD interface,
then echainiv will simply use its IV generator.

Otherwise, echainiv will encrypt a counter just like eseqiv but
it'll first xor it against a previously stored IV similar to
chainiv.
Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch converts the seqiv IV generator to work with the new
AEAD interface where IV generators are just normal AEAD algorithms.

Full backwards compatibility is paramount at this point since
no users have yet switched over to the new interface.  Nor can
they switch to the new interface until IV generation is fully
supported by it.

So this means we are adding two versions of seqiv alongside the
existing one.  The first one is the one that will be used when
the underlying AEAD algorithm has switched over to the new AEAD
interface.  The second one handles the current case where the
underlying AEAD algorithm still uses the old interface.

Both versions export themselves through the new AEAD interface.

Change the crypto 842 compression alg to use the software 842 compression
and decompression library.  Add the crypto driver_name as "842-generic".
Remove the fallback to LZO compression.

Previously, this crypto compression alg attemped 842 compression using
PowerPC hardware, and fell back to LZO compression and decompression if
the 842 PowerPC hardware was unavailable or failed.  This should not
fall back to any other compression method, however; users of this crypto
compression alg can fallback if desired, and transparent fallback tricks
callers into thinking they are getting 842 compression when they actually
get LZO compression - the failure of the 842 hardware should not be
transparent to the caller.

The crypto compression alg for a hardware device also should not be located
in crypto/ so this is now a software-only implementation that uses the 842
software compression/decompression library.
