Hi: This series of patches introduces IV generators which can be accessed through the givcrypt operation on block ciphers (other than crypto_blkcipher which should not be used for new code). The givcrypt operation is identical to encrypt except that the IV is generated by the algorithm instead of given by the user. Algorithms can either provide their own IV generator or (as most will do) use the default IV generators provided by the system. If no IV generator is specified by the system, then chainiv will be used for synchronous algorithms and eseqiv will be used for asynchronous algorithms. Counter mode algorithms (which include some stream ciphers) must choose something other than the default to ensure uniqueness for the IV.
