That's not right. ECB does not require an IV and therefore it
shouldn't have a non-zero IV size.

I'm not quite sure what you mean by crypto_lookup_skcipher not
liking a missing IV size. It appears to handle that case just
fine by returning the algorithm as is.

Can you show me what your /proc/crypto contains after you get the
aformentioned error?

Thanks,
