Hello Herbert, I'm trying to implement a driver for one hardware crypto engine, and on the current stage I work with AES algorithm, and I have a couple of open questions. 1) What shall be guaranteed from crypto engine by providing cra_blocksize and cra_alignmask values in crypto_alg definition? If they are provided, can I rely that in ablkcipher request I get aligned source and destination, and size of each chunk in sglist is aligned to cra_blocksize? 2) I've taken a look at http://www.mail-archive.com/linux-crypto@xxxxxxxxxxxxxxx/msg04903.html and I wonder, is someone working with SOCK_STREAM protocol realization for AF_ALG? And is there some planned activities about implementing setsockopt support for ALG_SET_IV, ALG_SET_OP etc. in algif_skcipher? Thank you in advance.
