Bluetooth: Convert SMP to use l2cap_chan infrastructure
Now that we have all the necessary pieces in place we can fully convert SMP to use the L2CAP channel infrastructure. This patch adds the necessary callbacks and removes the now unneeded conn->smp_chan pointer. One notable behavioral change in this patch comes from the following code snippet: - case L2CAP_CID_SMP: - if (smp_sig_channel(conn, skb)) - l2cap_conn_del(conn->hcon, EACCES); This piece of code was essentially forcing a disconnection if garbage SMP data was received. The l2cap_conn_del() function is private to l2cap_conn.c so we don't have access to it anymore when using the L2CAP channel callbacks. Therefore, the behavior of the new code is simply to return errors in the recv() callback (which is simply the old smp_sig_channel()), but no disconnection will occur.
