For adapters that do not support LE and ones where LE hasn't been enabled we shouldn't be trying to initiate background scanning. This patch adds an extra check to the hci_update_background_scan() to ensure that we bail out if HCI_LE_ENABLED is not set. Since we do allow user space to feed the kernel with LE connection parameters even when LE is not enabled we now need to also call hci_update_background_scan() as soon as LE gets enabled so that scanning gets started if necessary.

If we have both LE scanning and advertising simultaneously enabled we need a way to tell hci_connect_le() in which role to initiate a connection. This patch adds a new parameter to the function to give it the necessary information. For auto-connect and mgmt_pair_device we always use master role, whereas for L2CAP users (in practice sockets) we use slave role whenever HCI_ADVERTISING is set and master role otherwise.

The auth_type value which gets assigned to hci_conn->auth_type is something that's only used for BR/EDR connections and is of no value for LE connections. It makes therefore little sense to pass it to the hci_connect_le() function. This patch removes the parameter from the function. Signed-off-by:

Enabling passive scanning always when we're connectable aligns us with the BR/EDR page scanning. This is also consistent with the fact that the code dealing with passive scanning results will actively try to connect any direct advertising event when we're connectable. This patch implements the feature by adding the connectable condition to hci_update_background_scan() checks for starting scanning and by calling hci_update_background_scan() whenever the connectable state changes.

If we have an active discovery going on we shouldn't do any changes to LE scanning when hci_update_background_scan() is called (a call which can happen for many different reasons). This patch fixes the issue by returning from the function if the discovery state is anything else except DISCOVERY_STOPPED. Signed-off-by:

In a subsequent patch the hci_update_background_scan() function will depend on being able to know the current discovery state. For this to be possible we need to set the new state early in the function. Since we also need to check what the old state was this patch introduces an extra variable for tracking it. Signed-off-by:

Now that we have the process_adv_report() function doing the IRK lookup and updating the bdaddr we don't need to do this anymore in mgmt.c in the mgmt_device_found() function. Signed-off-by:

If we have devices set as to be connected we should connect to them even during normal discovery if we get a connectable advertising event. If we also have HCI_CONNECTABLE set we should connect ADV_DIRECT_IND events even to devices that we don't have in our pend_le_conns list. This patch implements such behavior by passing the advertising report type to check_pending_le_conn() and calls that function regardless of what type of scanning we are doing. Signed-off-by:

The hdev->send driver callback is mandatory to be provided by a driver before calling hci_register_dev. So enforce it and return EINVAL in case it is not available. All existing drivers are providing this callback anyway, so this is just an extra sanity check. Signed-off-by:

The drivers are allowed to just return an error from hdev->send callback and in that case the driver does not own the SKB. Which means that the caller has to free the SKB. Signed-off-by:

The isochronous endpoints are not valid when the Intel Bluetooth controller boots up in bootloader mode. So just mark these endpoints as broken and then they will not be configured. Signed-off-by:

When we get an LE connection complete event we should restart background scanning if there are any devices needing it. So far the code was only making the decision based on whether the completed connection had any stored parameters or not. This patch ensures that we trigger background scanning always when necessary.

When the driver sets HCI_QUIRK_RAW_DEVICE, the controller will be set as unconfigured. However running the unconfigured init procecure is not useful since raw-only devices are not allowed to change its configuration. This change skips the init procedure and just allows user channel operation for this device. Signed-off-by:

Intel Bluetooth devices that boot up in bootloader mode can not be used as generic HCI devices, but their HCI transport is still valuable and so bring that up as raw-only devices.

When we establish connections as a consequence of receiving an advertising report it makes no sense to wait the normal 20 second LE connection timeout. This patch modifies the hci_connect_le function to take an extra timeout value and uses a lower 2 second timeout for the auto-connection case. This timeout is intentionally chosen to be just a bit higher than the 1.28 second timeout that High Duty Cycle Advertising uses. Signed-off-by:

When an unconfigured controllers reaches the configured state, it is important to change the HCI_RAW flag. It indicates to userspace that the controller is fully operational. External configuration allows to bring the controller back into an unconfigured state. In that case make sure HCI_RAW flag is set again. Signed-off-by:

This adds support for changing the public device address. This feature is required by controllers that do not provide a public address and have HCI_QUIRK_INVALID_BDADDR set. Even if a controller has a public device address, this is useful when an embedded system wants to use its own value. As long as the driver provides the set_bdaddr callback, this allows changing the device address before powering on the controller. Signed-off-by:

When the external configuration triggers the switch to a configured controller, it means the setup needs to be run. Controllers that start out unconfigured have only run limited set of HCI commands. This is not enough for complete operation and thus run the setup procedure before announcing the new controller index. This introduces HCI_CONFIG flag as companion to HCI_SETUP flag. The HCI_SETUP flag is only used once for the initial setup procedure. And during that procedure hdev->setup driver callback is called. With the new HCI_CONFIG the switch from unconfigured to configured state is triggering the same setup procedure just without hdev->setup. This is required since bringing a controller back to unconfigured state from configured state is possible. Signed-off-by:

When calling Device Remove with BDADDR_ANY we should in a similar way emit Device Removed events as we do when removing a single device. Since we have to iterate the list and call device_removed() the dedicated hci_conn_params_clear_enabled() is not really useful anymore. This patch removes the helper function and does the event emission and list item removal in a single loop. Signed-off-by:

BR/EDR has the connection request and connection request rejection, but LE doesn't have anything similar. We still request LE connections to blocked devices to be disconnected but it's possible that ACL data slips through before that. The check in l2cap_recv_frame really only needs to be for LE and not BR/EDR because of this. Signed-off-by:

When a Bluetooth controller does not have a valid public Bluetooth address, then allow the driver to indicate this. If the quirk is set, the Bluetooth core will switch to unconfigured state first and will allow userspace to configure the address before starting the full initialization of the controller.
