* Bluetooth: Add hci_reset_dev() for driver triggerd stack resetMarcel Holtmann2014-11-021-0/+18
| | | | | | | | | Some Bluetooth drivers require to reset the upper stack. To avoid having all drivers send HCI Hardware Error events, provide a generic function to wrap the reset functionality.

* Bluetooth: Introduce BT_BREDR and BT_LE config optionsMarcel Holtmann2014-11-025-9/+19
| | | | | | | | | | | | | The current kernel options do not make it clear which modules are for Bluetooth Classic (BR/EDR) and which are for Bluetooth Low Energy (LE). To make it really clear, introduce BT_BREDR and BT_LE options with proper dependencies into the different modules. Both new options default to y to not create a regression with previous kernel config files. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Print error message for HCI_Hardware_Error eventMarcel Holtmann2014-11-021-0/+11
| | | | | | | | When the HCI_Hardware_Error event is send by the controller or injected by the driver, then at least print an error message. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Check status of command complete for HCI_ResetMarcel Holtmann2014-11-021-0/+3
| | | | | | | | | | When the HCI_Reset command returns, the status needs to be checked. It is unlikely that HCI_Reset actually fails, but when it fails, it is a bad idea to reset all values since the controller will have not reset its values in that case.

* ieee802154: 6lowpan: remove set of mac addressAlexander Aring2014-11-021-14/+0
| | | | | | | | | | Currently the ieee802154 6lowpan interface operates on wpan interfaces only. Setting the wpan mac address over 6lowpan interface is complex and maybe we can't never do this. This patch removes the set of mac address handling in ieee802154 6lowpan interface for now. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* mac802154: move phy settings into netlink receiveAlexander Aring2014-11-022-19/+21
| | | | | | | | | | | | All PHY attributes should be directly set to the transceiver after netlink. MAC attributes should be set by interface up. Currently the macparams netlink cmd contains mixed attributes of phy and mac settings. This patch moves all phy settings to the netlink receive function for setting macparams. This is the only way which doesn't change the userspace API and keep the deprecated netlink interface alive.

* mac802154: set panid address filter on ifupAlexander Aring2014-11-022-51/+4
| | | | | | | | | | | This patch moves the setting of hardware panid address filtering inside of interface up instead doing it it directly inside of netlink interface. The netlink call which can only be called when netif isn't running sets only the necessary panid value in sdata. After an interface up the address filter will be set with this value.

* mac802154: set short address filter on ifupAlexander Aring2014-11-022-6/+4
| | | | | | | | | | | This patch moves the setting of hardware short address filtering inside of interface up instead doing it it directly inside of netlink interface. The netlink call which can only be called when netif isn't running sets only the necessary short_addr value in sdata. After an interface up the address filter will be set with this value.

| | | | | | | | | | This patch moves the setting of hardware extended address filtering inside of interface up instead doing it directly inside of netlink interface. Also we don't need to set the sdata extended attribute in netlink. This is already done by ndo_set_mac_address of net_device_ops.

* ieee802154: don't allow to change addr while netif_runningAlexander Aring2014-11-021-2/+8
| | | | | | | | | | | This patch changes the actual behaviour for setting address attributes. We should not change addresses while netif_running is true. Furthermore when netif_running is running the address attributes becomes read only and we can remove locking mechanism in receive and transmit hothpaths of 802.15.4 subsystem.

* cfg802154: convert deprecated iface add and delAlexander Aring2014-11-025-19/+52
| | | | | | | | | | | This patch removes the wpan_phy callbacks for add and del an interface on a phy. Instead we introduce deprecated cfg802154 callbacks for this. Furthermore we introduce a new netlink interface nl802154 which use different callbacks. The deprecated function is to have a backwards compatibility with the current netlink interface.

* Bluetooth: Clear LE white list when resetting controllerMarcel Holtmann2014-10-301-0/+2
| | | | | | | | | | | | | | | The internal representation of the LE white list needs to be cleared when receiving a successful HCI_Reset command. A reset of the controller is expected to start with an empty LE white list. When the LE white list is not cleared on controller reset, the passive background scanning might skip programming the remote devices. Only changes to the LE white list are programmed when passive background is started.

* mac802154: rx: simplify crc receive handlingAlexander Aring2014-10-291-22/+12
| | | | | | | | | | | | | This patch change the actual crc handling while receive. Currently the IEEE802154_HW_RX_OMIT_CKSUM flag is used to filter a frame with a bad crc. This patch changes the behaviour of IEEE802154_HW_RX_OMIT_CKSUM to add a crc while receiving for the monitor interface. After monitor receiving we remove the crc for frame parsing. This affect the driver layer because all drivers sets IEEE802154_HW_RX_OMIT_CKSUM and deliver without checksum.

* Bluetooth: Fix check for direct advertisingJohan Hedberg2014-10-281-1/+1
| | | | | | | | | | | | | | These days we allow simultaneous LE scanning and advertising. Checking for whether advertising is enabled or not is therefore not a reliable way to determine whether directed advertising was used to trigger the connection creation.
