Since page scan might be enabled by Add Device we should not implicitly set connectable whenever something else than Set Connectable changes it. This patch makes sure that we don't set HCI_CONNECTABLE for these cases if there are any entries in the white list.

When we're removing the last item in the white list or adding the first one to it and HCI_CONNECTABLE is not set we need to update the current page scan. This patch adds a simple helper function for the purpose and calls it from the respective mgmt command handlers.

This patch extends the Add/Remove device commands by letting user space pass BR/EDR addresses to them. The resulting entries get stored in a new hdev->whitelist list. The idea is that we can now selectively accept connections from devices in the list even though HCI_CONNECTABLE is not set (the actual implementation of this is coming in a subsequent patch).

We already have several lists with struct bdaddr_list entries, and there will be more in the future. Since the operations for adding, removing, looking up and clearing entries in these lists are exactly the same it doesn't make sense to define new functions for every single list. This patch unifies the functions by passing the list_head to them instead of a hci_dev pointer.

If the connectable state change doesn't require any special HCI commands the set_connectable_update_settings() function is used instead of the set_connectable_complete() function. We must therefore make sure to call hci_update_background_scan() there as well. This code path is used also when we're powered off, but that's fine since hci_update_background_scan() has the necessary checks for it.

The connectable and discoverable mgmt settings are supported both for LE and BR/EDR controllers so they do not belong behind a lmp_bredr_capable() condition.

If any of the HCI commands from the hci_stop_discovery function were successfully sent we need to set the discovery state to STOPPING. The Stop Discovery code was already handling this, but the code in clean_up_hci_state was not. This patch updates the hci_stop_discovery to return a bool to indicate whether it queued any commands and the clean_up_hci_state() function respectively to look at the return value and call hci_discovery_set_state() if necessary.

Many controllers allow simultaneous active scanning and advertising (e.g. Intel and Broadcom) but some do not (e.g. CSR). It's therefore safest to implement mutual exclusion of these states in the kernel. This patch ensures that the two states are never entered simultaneously. Extra precaution needs to be taken for outgoing connection attempts in slave role (i.e. through directed advertising) in which case the operation that came first has precedence and the one that comes after gets a rejection.

When deciding to call disable_advertising() we're interested in the real state instead of the mgmt setting. Use therefore HCI_LE_ADV instead of the HCI_ADVERTISING flag. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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.

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.

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.

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.

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.

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.

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.

When powering off (hci_dev_do_close) we should clear both the pend_le_reports and pend_le_conns types of entries. When powering on respectively we should populate both lists. This patch converts the hci_pend_le_conns_clear() function into hci_pend_le_actions_clear() (which can now be static) and converts the restart_le_auto_conns() function into restart_le_actions().

Since params->action is used for both the pend_le_conns and pend_le_reports lists we can simplify the adding and deleting of the lists considerably. For example, when deleting entries in most situations we no-longer need to check the auto_connect value but can directly proceed with calling list_del_init on param->action (which is safe even if the entry is not part of any list).

Since the connection parameters are always a basis for adding entries to hdev->pend_le_conns (so far of type bdaddr_list) it's simpler and more efficient to have the parameters themselves be the entries in the pend_le_conns list.

The handler for variable length commands were trying to calculate the expected length of the command based on the given parameter count, and then comparing that with the received data. However, the expected count was stored in a u16 which can easily overflow. With a carefully crafted command this can then be made to match the given data even though the parameter count is actually way too big, resulting in a buffer overflow when parsing the parameters. This patch fixes the issue by calculating a per-command maximum parameter count and returns INVALID_PARAMS if it is exceeded.
