crypto: cfb - add support for Cipher FeedBack mode
TPM security routines require encryption and decryption with AES in CFB mode, so add it to the Linux Crypto schemes. CFB is basically a one time pad where the pad is generated initially from the encrypted IV and then subsequently from the encrypted previous block of ciphertext. The pad is XOR'd into the plain text to get the final ciphertext. https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#CFB Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
