2015-03-31crypto: testmgr - use CRYPTO_ALG_INTERNALStephan Mueller
Allocate the ciphers irrespectively if they are marked as internal or not. As all ciphers, including the internal ciphers will be processed by the testmgr, it needs to be able to allocate those ciphers.

2015-03-13crypto: testmgr - fix RNG return code enforcementStephan Mueller
Due to the change to RNGs to always return zero in success case, the invocation of the RNGs in the test manager must be updated as otherwise the RNG self tests are not properly executed any more.

2015-02-04crypto: testmgr - limit IV copy length in aead testsCristian Stoica
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.

2015-01-13crypto: testmgr - don't use interruptible wait in testsRabin Vincent
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.

2014-06-20crypto: drbg - Add DRBG test code to testmgrStephan Mueller
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.

The previous 8-way twofish/AVX implementation is therefore faster and this implementation should be removed.

2012-09-27crypto: testmgr - make test_aead also test 'dst != src' code pathsJussi Kivilinna
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 different than source buffer. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Acked-by: David S.

2012-08-01crypto: cast6 - add x86_64/avx assembler implementationJohannes Goetzfried
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. Tcrypt benchmark results: Intel Core i5-2500 CPU (fam:6, model:42, step:7) cast6-avx-x86_64 vs. cast6-generic 128bit key: (lrw:256bit) (xts:256bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.97x 1.00x 1.01x 1.01x 0.99x 0.97x 0.98x 1.01x 0.96x 0.98x 64B 0.98x 0.99x 1.02x 1.01x 0.99x 1.00x 1.01x 0.99x 1.00x 0.99x 256B 1.77x 1.84x 0.99x 1.85x 1.77x 1.77x 1.70x 1.74x 1.69x 1.72x 1024B 1.93x 1.95x 0.99x 1.96x 1.93x 1.93x 1.84x 1.85x 1.89x 1.87x 8192B 1.91x 1.95x 0.99x 1.97x 1.95x 1.91x 1.86x 1.87x 1.93x 1.90x 256bit key: (lrw:384bit) (xts:512bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.97x 0.99x 1.02x 1.01x 0.98x 0.99x 1.00x 1.00x 0.98x 0.98x 64B 0.98x 0.99x 1.01x 1.00x 1.00x 1.00x 1.01x 1.01x 0.97x 1.00x 256B 1.77x 1.83x 1.00x 1.86x 1.79x 1.78x 1.70x 1.76x 1.71x 1.69x 1024B 1.92x 1.95x 0.99x 1.96x 1.93x 1.93x 1.83x 1.86x 1.89x 1.87x 8192B 1.94x 1.95x 0.99x 1.97x 1.95x 1.95x 1.87x 1.87x 1.93x 1.91x Signed-off-by: Johannes Goetzfried <Johannes.Goetzfried@informatik.stud.uni-erlangen.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
