2014-11-02ieee802154: don't allow to change addr while netif_runningAlexander Aring
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.

2014-11-02cfg802154: convert deprecated iface add and delAlexander Aring
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.

2014-11-02mac802154: introduce mac802154_config_opsAlexander Aring
This patch introduces mac802154_config_ops struct. Like wireless this struct should be the only one interface between ieee802154 to mac802154 or possible HardMAC drivers. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-02cfg802154: introduce cfg802154_registered_deviceAlexander Aring
This patch introduce the cfg802154_registered_device struct. Like cfg80211_registered_device in wireless this should contain similar functionality for cfg802154. This patch should not change any behaviour. We just adds cfg802154_registered_device as container for wpan_phy struct.

2014-11-02ieee802154: remove default channel settingsAlexander Aring
This patch removes the default channel setting. A channel is always set and there is no default channel setting according 802.15.4. Drivers should set the default channel and page in probing routine. This behaviour is currently a lack of all 802.15.4 drivers. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2014-10-30Bluetooth: Clear LE white list when resetting controllerMarcel Holtmann
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.

2014-10-29mac802154: rx: simplify crc receive handlingAlexander Aring
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.

This patch splits the IEEE802154_HW_OMIT_CKSUM hardware flag into IEEE802154_HW_TX_OMIT_CKSUM and IEEE802154_HW_RX_OMIT_CKSUM. This is useful to deliver the received crc from the driver layer to the monitor interface. At the moment we can't do that without change the xmit handling.

2014-10-28mac802154: move local started handlingAlexander Aring
This patch removes the current handling of started boolean. This is actually dead code, because mac802154_netdev_register can't never be called before ieee802154_register_hw.

2014-10-28Bluetooth: Fix check for direct advertisingJohan Hedberg
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. The appropriate place to check (instead of the hdev context) is the connection role that's stored in the hci_conn. This patch fixes such a check in le_conn_timeout() which could otherwise lead to incorrect HCI commands being sent.

2014-10-28Bluetooth: Fix LE connection timeout deadlockJohan Hedberg
The le_conn_timeout() may call hci_le_conn_failed() which in turn may call hci_conn_del(). Trying to use the _sync variant for cancelling the conn timeout from hci_conn_del() could therefore result in a deadlock. This patch converts hci_conn_del() to use the non-sync variant so the deadlock is not possible.

2014-10-28Bluetooth: Revert SMP self-test patchesJohan Hedberg
This reverts commits c6992e9ef2a17e9738b7bb8a03a7fe581a8f9977 and 4cd3362da899a59955146851dd860198b0aaaa75. The reason for the revert is that we cannot have more than one module initialization function and the SMP one breaks the build with modular kernels. As the proper fix for this is right now looking non-trivial it's better to simply revert the problematic patches in order to keep the upstream tree compilable.
