Cristian Stoica 424a5da691 crypto: testmgr - limit IV copy length in aead tests
The working copy of IV is the same size as the transformation's IV.
It is not necessary to copy more than that from the template since
iv_len is usually less than MAX_IVLEN and the rest of the copied data
is garbage.

This gcm variant is popular for ipsec use, and there are folks who would
like to use it while in fips mode. Mark it with fips_allowed=1 to

Rabin Vincent 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.

This reverts commit cf1521a1a5.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 8-way twofish/AVX
implementation is therefore faster and this implementation should be removed.

Converting this implementation to use the same method as in twofish/AVX for
table look-ups would give additional ~3% speed up vs twofish/AVX, but would
hardly be worth of the added code and binary size.

Currrently test_aead uses same buffer for destination and source. However
in any places, 'dst != src' take different path than 'dst == src' case.

Therefore make test_aead also run tests with destination buffer being

Johannes Goetzfried 4ea1277d30 crypto: cast6 - add x86_64/avx assembler implementation
This patch adds a x86_64/avx assembler implementation of the Cast6 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 functions from the generic 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.
