      crypto: testmgr - add aead cbc des, des3_ede tests · 5208ed2c
      Nitesh Lal authored
      Test vectors were taken from existing test for
      CBC(DES3_EDE). Associated data has been added to test vectors.
      HMAC computed with Crypto++ has been used. Following algos have
      been covered.
      
              (a) "authenc(hmac(sha1),cbc(des))"
              (b) "authenc(hmac(sha1),cbc(des3_ede))"
              (c) "authenc(hmac(sha224),cbc(des))"
              (d) "authenc(hmac(sha224),cbc(des3_ede))"
              (e) "authenc(hmac(sha256),cbc(des))"
              (f) "authenc(hmac(sha256),cbc(des3_ede))"
              (g) "authenc(hmac(sha384),cbc(des))"
              (h) "authenc(hmac(sha384),cbc(des3_ede))"
              (i) "authenc(hmac(sha512),cbc(des))"
              (j) "authenc(hmac(sha512),cbc(des3_ede))"

      crypto: caam - fix aead sglen for case 'dst != src' · bbf9c893
      Horia Geanta authored
      For aead case when source and destination buffers are different,
      there is an incorrect assumption that the source length includes the ICV
      length. Fix this, since it leads to an oops when using sg_count() to
      find the number of nents in the scatterlist:

      crypto: twofish - add x86_64/avx assembler implementation · 107778b5
      Johannes Goetzfried authored
      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.
