This patch converts rfc4106-gcm-aesni to the new AEAD interface.
The low-level interface remains as is for now because we can't
touch it until cryptd itself is upgraded.
In the conversion I've also removed the duplicate copy of the
context in the top-level algorithm. Now all processing is carried
out in the low-level __driver-gcm-aes-aesni algorithm.

Patch e68410ebf6 ("crypto: x86/sha512_ssse3 - move SHA-384/512
SSSE3 implementation to base layer") changed the prototypes of the
core asm SHA-512 implementations so that they are compatible with
the prototype used by the base layer.
However, in one instance, the register that was used for passing the
input buffer was reused as a scratch register later on in the code,
and since the input buffer param changed places with the digest param
-which needs to be written back before the function returns- this
resulted in the scratch register to be dereferenced in a memory write
operation, causing a GPF.
Fix this by changing the scratch register to use the same register as
the input buffer param again.

There is no reason to use MOVQ to load a non-negative immediate

the upper 32 bits are zero-extended by the CPU.
This makes the code a bit smaller, while leaving functionality

The kernel crypto API logic requires the caller to provide the
length of (ciphertext || authentication tag) as cryptlen for the
AEAD decryption operation. Thus, the cipher implementation must
calculate the size of the plaintext output itself and cannot simply use
cryptlen.
The RFC4106 GCM decryption operation tries to overwrite cryptlen memory
in req->dst. As the destination buffer for decryption only needs to hold
the plaintext memory but cryptlen references the input buffer holding
(ciphertext || authentication tag), the assumption of the destination
buffer length in RFC4106 GCM operation leads to a too large size. This
patch simply uses the already calculated plaintext size.
In addition, this patch fixes the offset calculation of the AAD buffer
pointer: as mentioned before, cryptlen already includes the size of the
tag. Thus, the tag does not need to be added. With the addition, the AAD
will be written beyond the already allocated buffer.
Note, this fixes a kernel crash that can be triggered from user space
via AF_ALG(aead) -- simply use the libkcapi test application
from [1] and update it to use rfc4106-gcm-aes.
Using [1], the changes were tested using CAVS vectors to demonstrate
that the crypto operation still delivers the right results.

These patches fix the RFC4106 implementation in the aesni-intel
module so it supports 192 & 256 bit keys.
Since the AVX support that was added to this module also only
supports 128 bit keys, and this patch only affects the SSE
implementation, changes were also made to use the SSE version
if key sizes other than 128 are specified.
RFC4106 specifies that 192 & 256 bit keys must be supported (section
8.4).
Also, this should fix Strongswan issue 341 where the aesni module
needs to be unloaded if 256 bit keys are used:
http://wiki.strongswan.org/issues/341
This patch has been tested with Sandy Bridge and Haswell processors.
With 128 bit keys and input buffers > 512 bytes a slight performance
degradation was noticed (~1%). For input buffers of less than 512
bytes there was no performance impact. Compared to 128 bit keys,
256 bit key size performance is approx. .5 cycles per byte slower
on Sandy Bridge, and .37 cycles per byte slower on Haswell (vs.
SSE code).
This patch has also been tested with StrongSwan IPSec connections
where it worked correctly.

Commit 5d26a105b5 ("crypto: prefix module autoloading with "crypto-"")
changed the automatic module loading when requesting crypto algorithms
to prefix all module requests with "crypto-". This requires all crypto
modules to have a crypto specific module alias even if their file name
would otherwise match the requested crypto algorithm.
Even though commit 5d26a105b5 added those aliases for a vast amount of
modules, it was missing a few. Add the required MODULE_ALIAS_CRYPTO
annotations to those files to make them get loaded automatically, again.
This fixes, e.g., requesting 'ecb(blowfish-generic)', which used to work
with kernels v3.18 and below.
Also change MODULE_ALIAS() lines to MODULE_ALIAS_CRYPTO(). The former
won't work for crypto modules any more.

The "by8" counter mode optimization is broken for 128 bit keys with
input data longer than 128 bytes. It uses the wrong key material for
en- and decryption.
The key registers xkey0, xkey4, xkey8 and xkey12 need to be preserved
in case we're handling more than 128 bytes of input data -- they won't
get reloaded after the initial load. They must therefore be (a) loaded
on the first iteration and (b) be preserved for the latter ones. The
implementation for 128 bit keys does not comply with (a) nor (b).
Fix this by bringing the implementation back to its original source
and correctly load the key registers and preserve their values by
*not* re-using the registers for other purposes.
Kudos to James for reporting the issue and providing a test case
showing the discrepancies.

The "by8" CTR AVX implementation fails to propperly handle counter
overflows. That was the reason it got disabled in commit 7da4b29d49
("crypto: aesni - disable "by8" AVX CTR optimization").
Fix the overflow handling by incrementing the counter block as a double
quad word, i.e. a 128 bit, and testing for overflows afterwards. We need
to use VPTEST to do so as VPADD* does not set the flags itself and
silently drops the carry bit.
As this change adds branches to the hot path, minor performance
regressions might be a side effect. But, OTOH, we now have a conforming
implementation -- the preferable goal.
A tcrypt test on a SandyBridge system (i7-2620M) showed almost identical
numbers for the old and this version with differences within the noise
range. A dm-crypt test with the fixed version gave even slightly better
results for this version. So the performance impact might not be as big
as expected.

handles counter block overflows differently. It only accounts the right
most 32 bit as a counter -- not the whole block as all other
implementations do. This makes it fail the cryptomgr test #4 that
specifically tests this corner case.
