setkey() is for crypto user is defined as:
static inline int crypto_ablkcipher_setkey(struct crypto_ablkcipher
*tfm,
const u8 *key, unsigned int keylen)
{
return crypto_ablkcipher_crt(tfm)->setkey(tfm, key, keylen);
}
If the key is not properly aligned by the caller, the cipher gets an
unaligned key.
What do you recommend?
