When doing "modeprobe tcrypt mode=10", the following error will show in dmesg. alg: skcipher: Failed to load transform for ctr(aes): -22 alg: skcipher: Failed to load transform for ctr(aes): -22 tcrypt: one or more tests failed! Because ctr(aes) testing code will allocate ctr(aes) with geniv, but defualt geniv mode may not work with ctr(aes). As that of rfc3686, this is fixed via specifying geniv mode to "seqiv".
