In multiple functions, the algorithm fields are read after its reference
is dropped through crypto_mod_put. In this case, the algorithm memory
may be freed, resulting in use-after-free bugs. This patch delays the
put operation until the algorithm is never used.Fixes: 79c65d179a40 ("crypto: cbc - Convert to skcipher")
Fixes: a7d85e06ed80 ("crypto: cfb - add support for Cipher FeedBack mode")
Fixes: 043a44001b9e ("crypto: pcbc - Convert to skcipher")

crypto_cfb_decrypt_segment() incorrectly XOR'ed generated keystream with
IV, rather than with data stream, resulting in incorrect decryption.
Test vectors will be added in the next patch.Signed-off-by: Dmitry Eremin-Solenikov

We avoid various VLAs[1] by using constant expressions for block size

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
