• 4943ba16b   crypto: include crypto- module prefix in template ... Browse Code »

  This adds the module loading prefix "crypto-" to the template lookup
  as well.

  For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly
  includes the "crypto-" prefix at every level, correctly rejecting "vfat":

  net-pf-38
  algif-hash
  crypto-vfat(blowfish)
  crypto-vfat(blowfish)-all
  crypto-vfat

• 50b6544e1   [CRYPTO] cbc: Require block size to be a power of 2 ... Browse Code »

  All common block ciphers have a block size that's a power of 2. In fact,
  all of our block ciphers obey this rule.

  If we require this then CBC can be optimised to avoid an expensive divide
  on in-place decryption.

  I've also changed the saving of the first IV in the in-place decryption
  case to the last IV because that lets us use walk->iv (which is already
  aligned) for the xor operation where alignment is required.

• ebc610e5b   [CRYPTO] templates: Pass type/mask when creating instances ... Browse Code »

  This patch passes the type/mask along when constructing instances of
  templates. This is in preparation for templates that may support
  multiple types of instances depending on what is requested. For example,
  the planned software async crypto driver will use this construct.

  For the moment this allows us to check whether the instance constructed
  is of the correct type and avoid returning success if the type does not
  match.

• db131ef90   [CRYPTO] cipher: Added block ciphers for CBC/ECB ... Browse Code »

  This patch adds two block cipher algorithms, CBC and ECB. These
  are implemented as templates on top of existing single-block cipher
  algorithms. They invoke the single-block cipher through the new
  encrypt_one/decrypt_one interface.

  This also optimises the in-place encryption and decryption to remove
  the cost of an IV copy each round.
