      crypto: add missing crypto module aliases · 3e14dcf7
      Mathias Krause authored
      Commit 5d26a105 ("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 5d26a105 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.
      
      Fixes: 5d26a105 ("crypto: prefix module autoloading with "crypto-"")

      crypto: des_3des - add x86-64 assembly implementation · 6574e6c6
      Jussi Kivilinna authored
      Patch adds x86_64 assembly implementation of Triple DES EDE cipher algorithm.
      Two assembly implementations are provided. First is regular 'one-block at
      time' encrypt/decrypt function. Second is 'three-blocks at time' function that
      gains performance increase on out-of-order CPUs.
      
      tcrypt test results:
      
      Intel Core i5-4570:
      
      des3_ede-asm vs des3_ede-generic:

      crypto: des3_ede - permit weak keys unless REQ_WEAK_KEY set · ad79cdd7
      Jarod Wilson authored
      While its a slightly insane to bypass the key1 == key2 ||
      key2 == key3 check in triple-des, since it reduces it to the
      same strength as des, some folks do need to do this from time
      to time for backwards compatibility with des.
      
      My own case is FIPS CAVS test vectors. Many triple-des test
      vectors use a single key, replicated 3x. In order to get the
      expected results, des3_ede_setkey() needs to only reject weak
      keys if the CRYPTO_TFM_REQ_WEAK_KEY flag is set.
      
      Also sets a more appropriate RES flag when a weak key is found.

      Thanks for the suggestion, the init() is replaced with
      
      	<algorithm name>_mod_init ()
      
      and fini () is replaced with <algorithm name>_mod_fini.

      [CRYPTO] api: Get rid of flags argument to setkey · 560c06ae
      Herbert Xu authored
      Now that the tfm is passed directly to setkey instead of the ctx, we no
      longer need to pass the &tfm->crt_flags pointer.
      
      This patch also gets rid of a few unnecessary checks on the key length
      for ciphers as the cipher layer guarantees that the key length is within
      the bounds specified by the algorithm.
      
      Rather than testing dia_setkey every time, this patch does it only once
      during crypto_alloc_tfm.  The redundant check from crypto_digest_setkey
      is also removed.

      [CRYPTO] all: Pass tfm instead of ctx to algorithms · 6c2bb98b
      Herbert Xu authored
      Up until now algorithms have been happy to get a context pointer since
      they know everything that's in the tfm already (e.g., alignment, block
      size).
      
      However, once we have parameterised algorithms, such information will
      be specific to each tfm.  So the algorithm API needs to be changed to
      pass the tfm structure instead of the context pointer.
      
      This patch is basically a text substitution.  The only tricky bit is
      the assembly routines that need to get the context pointer offset
      through asm-offsets.h.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
