Which code exactly? Yes I'm curious :-) I'm thinking about how to remove the need for a device to support all the algorithms when we open a session. By using a fake "crypto virtual device" to open and dispatch crypto requests to real devices or to cryptosoft. But i don't have any code to show yet. There is one thing I'm asking about crypto(9): - I doubt that the migration of a session is safe and I think that would be far easier to prevent a driver to unregister when there are some pending sessions on it? glxsb and padlock do not allow to unregister in this case. I've looked quickly the code of geli or ipsec. If the crypto framework returns EAGAIN because the migration of the session, they restart a crypto_dispatch(crp) but the datas in crp->crp_buf can be corrupted by the previous crypto operation (IMHO, may be i've missed something)?
