Jussi Kivilinna 56d76c96a9 crypto: serpent - add AVX2/x86_64 assembler implementation of serpent cipher
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.

Jussi Kivilinna cf1521a1a5 crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipher
Patch adds AVX2/x86-64 implementation of Twofish cipher, requiring 16 parallel
blocks for input (256 bytes). Table look-ups are performed using vpgatherdd
instruction directly from vector registers and thus should be faster than
earlier implementations. Implementation also uses 256-bit wide YMM registers,
which should give additional speed up compared to the AVX implementation.

Johannes Goetzfried 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.

Jarod Wilson 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.

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.

Herbert Xu f8b0d4d09d crypto: testmgr - Dynamically allocate xbuf and axbuf
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.

Jarod Wilson 29ecd4ab3d crypto: testmgr - Print self-test pass notices in fips mode
According to our FIPS CAVS testing lab guru, when we're in fips mode,
we must print out notices of successful self-test completion for
every alg to be compliant.

New and improved v2, without strncmp crap. Doesn't need to touch a flag
though, due to not moving the notest label around anymore.

Applies atop '[PATCH v2] crypto: catch base cipher self-test failures
in fips mode'.

Personally, I wouldn't mind seeing this info printed out regardless of
whether or not we're in fips mode, I think its useful info, but will
stick with only in fips mode for now.

Jarod Wilson e08ca2da39 crypto: testmgr - Add ansi_cprng test vectors
Add ANSI X9.31 Continuous Pseudo-Random Number Generator (AES mode),
aka 'ansi_cprng' test vectors, taken from Appendix B.2.9 and B.2.10
of the NIST RNGVS document, found here:
    http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf

Successfully tested against both the cryptodev-2.6 tree and a Red
Hat Enterprise Linux 5.4 kernel, via 'modprobe tcrypt mode=150'.

The selection of 150 was semi-arbitrary, didn't seem like it should
go any place in particular, so I started a new range for rng tests.

Jarod Wilson 7647d6ce20 crypto: testmgr - Add infrastructure for ansi_cprng self-tests
Add some necessary infrastructure to make it possible to run
self-tests for ansi_cprng. The bits are likely very specific
to the ANSI X9.31 CPRNG in AES mode, and thus perhaps should
be named more specifically if/when we grow additional CPRNG
support...

Successfully tested against the cryptodev-2.6 tree and a
Red Hat Enterprise Linux 5.x kernel with the follow-on
patch that adds the actual test vectors.

Add an array of encryption and decryption + verification self-tests
for rfc4309(ccm(aes)).

Test vectors all come from sample FIPS CAVS files provided to
Red Hat by a testing lab. Unfortunately, all the published sample
vectors in RFC 3610 and NIST Special Publication 800-38C contain nonce
lengths that the kernel's rfc4309 implementation doesn't support, so
while using some public domain vectors would have been preferred, its
not possible at this time.

Neil Horman d12d6b6d37 crypto: testmgr - Trigger a panic when self test fails in FIPS mode
The FIPS specification requires that should self test for any supported
crypto algorithm fail during operation in fips mode, we need to prevent
the use of any crypto functionality until such time as the system can
be re-initialized.  Seems like the best way to handle that would be
to panic the system if we were in fips mode and failed a self test.
This patch implements that functionality.  I've built and run it
successfully.
