The legacy ioctls for device specific commands including inquiry are not support by AMP controllers. So just reject them right away instead of trying to send the HCI command and wait for failure from the actual hardware. Signed-off-by:

When changing the alternate setting for the ISOC endpoints, use the hci_conn_num() helper function to count currently established SCO and eSCO connections and store the the value. This avoids direct access to the connection hash. In addition use the stored value instead accessing the connection hash over and over again. Signed-off-by:

When checking for the current number of LE connections, use hci_conn_num() function instead of a full blown lookup within the connection hash or direct access of the counters. In the case of re-enabling advertising, it is more useful to check for any connection attempt or existing connection. Signed-off-by:

When the HCI_SETUP flag is set the controller has not yet been announced over mgmt and therefore doesn't exist from that perspective. If we nevertheless get a mgmt command for it we should respond with the appropriate INVALID_INDEX error. Signed-off-by:

The l2cap_recv_frame function is expected to take ownership and eventually free the skb passed to it. We need to ensure that the conn->rx_skb pointer is no longer reachable when calling l2cap_recv_frame so that no other function, such as l2cap_conn_del, may think that it can free conn->rx_skb. An actual situation when this can happen is when smp_sig_channel (called from l2cap_recv_frame) fails and l2cap_conn_del gets called as a consequence. The l2cap_conn_del function would then try to free conn->rx_skb, but as the same skb was just passed to smp_sig_channel and freed we get a double-free. Signed-off-by:

The support for Bluetooth High Speed can only be enabled on controllers where also Secure Simple Pairing has been enabled. Trying to enable high speed when SSP is disabled will result into an error. Disabling SSP will at the same time disable high speed as well. It is required to enforce this dependency on SSP since high speed support is only defined for authenticated, unauthenticated and debug link keys. These link key types require SSP. Signed-off-by:

This patch does some code refactoring in hci_connect_le() by moving the exception code into if statements and letting the main flow in first level of function scope. It also adds extra comments to improve the code readability. Signed-off-by:

This patch introduces a new helper, which uses the HCI request framework, for creating LE connectons. All the handling is now done by this function so we can remove the hci_cs_le_create_conn() event handler. This patch also removes the old hci_le_create_connection() since it is not used anymore.

We only (re)enable advertising when LE is disconnected. Trying to enable advertising using mgmt_set_advertising while connected should simply change the flag but not do anything else (until the connection gets dropped). This patch fixes this by making an LE connection lookup to determine whether there are any connected devices or not. Signed-off-by:

The management interface only operates on BR/EDR controllers. The check for the power down notification is a bit intermixed with the check if controller auto power off is active. Since there are more than just BR/EDR controllers supported, make this check explicit since the auto power off check also applies to AMP controllers and it has to happen in this exact order. Otherwise the bit will not be cleared. Signed-off-by:

Even AMP controllers should be powered off after the setup phase. It is not a good idea to keep AMP controllers powered on all the time if they are not in use. Power on of the AMP controller can either be done manually via command line commands or directly via A2MP. Especially since there is an indication in A2MP for powered down controllers that can be activated. Signed-off-by:

When the all LE connections have been disconneted, then it is up to the host to re-enable advertising at that point. To ensure that the correct advertising parameters are used, force the usage of the common helper to enable advertising. The change just moves the manual enabling of advertising from the event handler into the management core so that the helper can be actually shared. Signed-off-by:

The LE advertising parameters can only be modified when advertising is disabled. So before enabling it, make sure the controller has all the right parameters. Right now all default values are used and thus this does no change any existing behavior. One minor exception is that in case of single mode LE-only controllers without a public address, now the random address is used for advertising. Signed-off-by:
