What I mean is bulk mode and sector mode's difference is not only the IV handling method, but also the method to map the data with scatterlists. Then we have two processes in dm-crypt ( crypt_convert_block() and crypt_convert_bulk_block() ) to handle the data, so we can not handle every algorithm with the bulk interface. > > Cheers, > -- > Email: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> > Home Page: http://gondor.apana.org.au/~herbert/ > PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt -- Baolin.wang Best Regards -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
