2013-10-21Bluetooth: Fix enabling fast connectable on LE-only controllersJohan Hedberg
The current "fast connectable" feature is BR/EDR-only, so add a proper check for BR/EDR support before proceeding with the associated HCI commands. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Update Set Discoverable to support LEJohan Hedberg
This patch updates the Set Discoverable management command to also be applicable for LE. In particular this affects the advertising flags where we can say "general discoverable" or "limited discoverable". Since the device flags may not be up-to-date when the advertising data is written this patch introduces a get_adv_discov_flags() helper function which also looks at any pending mgmt commands (a pending set_discoverable would be the exception when the flags are not yet correct). The patch also adds HCI_DISCOVERABLE flag clearing to the mgmt_discoverable_timeout function, since the code was previously relying on the mgmt_discoverable callback to handle this, which is only called for the BR/EDR-only HCI_Write_Scan_Enable command.

2013-10-20Bluetooth: Move HCI_LIMITED_DISCOVERABLE changes to a general placeJohan Hedberg
We'll soon be introducing also LE support for the Set Discoverable management command, so move the HCI_LIMITED_DISCOVERABLE flag clearing and setting out from the if-branch that is only used for a BR/EDR specific HCI command.

2013-10-20Bluetooth: Fix sending write_scan_enable when BR/EDR is disabledJohan Hedberg
We should only send the HCI_Write_Scan_Enable command from mgmt_set_powered_failed() when BR/EDR support is enabled. This is particularly important when the discoverable setting is also tied to LE.

2013-10-20Bluetooth: Fix updating settings when there are no HCI commands to sendJohan Hedberg
It is possible that the Set Connectable management command doesn't cause any HCI commands to send (such as when BR/EDR is disabled). We can't just send a response to user space in this case but must also update the necessary device flags and settings. This patch fixes the issue by using the recently introduced set_connectable_update_settings function.

2013-10-20Bluetooth: Refactor set_connectable settings update to separate functionJohan Hedberg
We will need to directly update the device flags and notify user space of the new settings not just when we're powered off but also if it turns out that there are no HCI commands to send (which can happen in particular when BR/EDR is disabled). Since this is a considerable amount of code, refactor it to a separate function so it can be reused for the "no HCI commands to send" case.

2013-10-20Bluetooth: Add missing check for BREDR_ENABLED flag in update_class()Johan Hedberg
We shouldn't be sending the HCI_Write_Class_Of_Device command when BR/EDR is disabled since this is a BR/EDR-only command. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-20Bluetooth: Check for flag instead of features in update_adv_data()Johan Hedberg
It's better to check for the device flag instead of device features so that we avoid unnecessary HCI commands when the feature is supported but disabled (i.e. the flag is unset). Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2013-10-19Bluetooth: Select the own address type during initial setup phaseMarcel Holtmann
The own address type is based on the fact if the controller has a public address or not. This means that this detail can be just configured once during setup phase. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2013-10-16Bluetooth: Rename update_ad into update_adv_dataMarcel Holtmann

2013-10-16Bluetooth: Store device name in scan response dataMarcel Holtmann
The scan response data is a better place to store the device name since it has more space available and is also enforcing privacy. When the controller is advertising, the connectable setting decides if ADV_IND or ADV_NONCONN_IND is used. In case of ADV_IND, the remote side is allowed to request the scan response data. Same as with BR/EDR where either EIR is used or a remote name request. In non-connectable mode, the device name is not available since it is not allowed to request scan response data. Same as in BR/EDR where the device is non-discoverable and no name requests are answered. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Set the scan response data when neededMarcel Holtmann

2013-10-16Bluetooth: Rename create_ad into create_adv_dataMarcel Holtmann
Rename the create_ad function into create_adv_data to make it clear that it is used to create the advertising data.

2013-10-15Bluetooth: Update class of device on discoverable timeoutMarcel Holtmann
When the discoverable timeout triggers and limited discoverable mode was used, then the class of device needs to be updated to remove the limited discoverable bit. To keep the class of device logic in a central place, expose a new function mgmt_discoverable_timeout that can be called from the timeout callback. In case the class of device value needs updating, it will add the HCI command to the transaction.

2013-10-15Bluetooth: Add support for entering limited discoverable modeMarcel Holtmann
The limited discoverable mode should be used when a device is only discoverable for a certain amount of time and after that it returns back into being non-discoverable. This adds another option to the set discoverable management command to clearly distinguish limited discoverable from general discoverable mode. While the general discoverable mode can be set with a specific timeout or as permanent setting, the limited discoverable mode requires a timeout. The timeout is flexible and the kernel will not enforce any specific limitations. That GAP part of this is required by userspace to enforce according to the Bluetooth core specification. Devices in limited discoverable mode can still be found by the general discovery procedure. It is mandatory that a device sets both GIAC and LIAC when entering limited discoverable mode.

2013-10-15Bluetooth: Simplify the code for re-arming discoverable timeoutMarcel Holtmann

2013-10-15Bluetooth: Move arming of discoverable timeout to complete handlerMarcel Holtmann
The discoverable timeout is currently armed from hci_event.c and causes some side effects when using HCI commands instead of the management interface. To make this clear, only arm the discoverable timeout from the management command complete handler.

2013-10-15Bluetooth: Update class of device after changing discoverable modeMarcel Holtmann
When the discoverable mode gets changed, ensure that the class of device value has the correct limited discoverable bit value set. Since the class of device HCI command will only be send to the controller when the value changes, it is safe to just always trigger the update.

2013-10-15Bluetooth: Update advertising data based on management commandsMarcel Holtmann
Magically updating the advertising data when some random command enables advertising in the controller is not really a good idea. It also caused a bit of complicated code with the exported hci_udpate_ad function that is shared from many places. This patch consolidates the advertising data update into the management core. It also makes sure that when powering on with LE enabled or later on enabling LE the controller has a good default for advertising data.

2013-10-14Bluetooth: Convert Set Discoverable to use an asynchronous requestJohan Hedberg
This patch converts Set Discoverable to use an asynchronous request along with its own completion callback.

2013-10-14Bluetooth: Fix updating scan mode in set_bredr()Johan Hedberg
Now that the connectable setting is also applicable for the LE side it's possible that the HCI_CONNECTABLE flag is already set when changing the BR/EDR setting from false to true while the controller is powered. In this situation we need to update the BR/EDR scan mode to reflect the setting. Additionally, since HCI_CONNECTABLE also applies to LE we must not clear the HCI_CONNECTABLE flag when disabling bredr.

2013-10-14Bluetooth: Make Set Connectable also update the LE advertising typeJohan Hedberg
This patch updates the Set Connectable Management command to also update the LE advertising type to either connectable or non-connectable advertising. An extra helper function is needed for getting the right advertising type since we can not only rely on the HCI_CONNECTABLE flag but must also check for a pending Set Connectable command (in which case the flag does not yet have its final value).

2013-10-14Bluetooth: Add missing error handling for Set ConnectableJohan Hedberg

2013-10-14Bluetooth: Move more logic into set_connectable complete callbackJohan Hedberg

2013-10-14Bluetooth: Reorganize set_connectable HCI command sendingJohan Hedberg
This patch moves all the decisions of which HCI commands to send (or not to send) to the code between hci_req_init() and hci_req_run() this allows us to further extend the request with further commands but still keep the same logic of handling whether to return a direct mgmt response in the case that no HCI commands were sent.

2013-10-13Bluetooth: Remove pointless bdaddr_to_le() helper functionMarcel Holtmann
The bdaddr_to_le() function tries to convert the internal address type to one that matches the HCI address type for LE. It does not handle any address types not used by LE and in the end just make the code a lot harder to read. So instead of just hiding behind a magic function, just convert the internal address type where it needs to be converted. And it turns out that these are only two cases anyway. One when creating new LE connections and the other when loading the long term keys. In both cases this makes it more clear on what it going on.
