2015-01-14Bluetooth: btusb: Add internal recv_event callback for event processingMarcel Holtmann
Some new upcoming drivers need to process HCI events or take extra actions based on them before handing the event to the Bluetooth core for processing. The new recv_event callback allows exactly such an internal behavior. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2015-01-12Bluetooth: Read stored link key information when powering on controllerMarcel Holtmann
The information about max stored link keys and current stored link keys should be read at controller initialization. So issue HCI Read Stored Link Key command with BDADDR_ANY and read_all flag set to 0x01 to retrieve this information.

2015-01-12Bluetooth: Handle command complete event for HCI Read Stored Link KeysMarcel Holtmann
When the HCI Read Stored Link Keys command completes it gives useful information of the current stored keys and maximum keys a controller can actually store. So process this event and store these information in hci_dev structure. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2015-01-12Bluetooth: Replace send_monitor_event with queue_monitor_skbMarcel Holtmann
The send_monitor_event function is essentially the same as the newly introduced queue_monitor_skb. So instead of having duplicated code, replace send_monitor_event with queue_monitor_skb. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-01-12Bluetooth: Create generic queue_monitor_skb helper functionMarcel Holtmann
The hci_send_to_monitor function contains generic code for queueing the packet into the receive queue of every monitor client. To avoid code duplication, create a generic queue_monitor_skb function to interate over all monitor sockets.

2015-01-12Bluetooth: Simplify packet copy in hci_send_to_monitor functionMarcel Holtmann
Within the monitor functionality, the global atomic variable called monitor_promisc ensures that no memory allocation happend when there is actually no client listening. This means it is safe to just create a copy of the skb since it is guaranteed that at least one client exists. No extra checks needed.

2015-01-12Bluetooth: Add opcode parameter to hci_req_complete_t callbackMarcel Holtmann
When hci_req_run() calls its provided complete function and one of the HCI commands in the sequence fails, then provide the opcode of failing command. In case of success HCI_OP_NOP is provided since all commands completed. This patch fixes the prototype of hci_req_complete_t and all its users.

2015-01-08ieee802154: 6lowpan: fix Makefile entryAlexander Aring
Since commit ea81ac2e7050798109356150ea16e71622a5c329 ("ieee802154: create 6lowpan sub-directory") we have a subdirectory for the ieee802154 6lowpan implementation. This commit also moves the Kconfig entry inside of net/ieee802154/6lowpan/ and forgot to rename the Makefile entry from obj-$(CONFIG_IEEE802154_6LOWPAN) to obj-y and handle the obj-$(CONFIG_IEEE802154_6LOWPAN) inside the created 6lowpan directory.

This patch renames the internal header for af802154. This naming convention is like ieee802154_i.h in mac802154 and avoids naming confusing with the global af802154 header.

2015-01-06Bluetooth: btmrvl: fix race issue while stopping main threadAmitkumar Karwar
btmrvl_remove_card() calls kthread_stop() to stop the main thread, but kthread_should_stop() is checked when all the activities are done in the main thread before sleeping. We will have kthread_should_stop() check as soon as main thread is woken up. This fixes a crash issue caused due to an invalid memory access while unnecessarily processing interrupts after card removal.

2015-01-03Bluetooth: Remove dead code for manufacturer inquiry mode quirksMarcel Holtmann
There are some old Bluetooth modules from Silicon Wave and Broadcom which support Inquiry Result with RSSI, but do not advertise it. The core has quirks in the code to enable that inquiry mode. However as it stands right now, that code is not even executed since entering the function to determine which inquiry mode requires that the device has the feature bit for Inquiry Result with RSSI set in the first place. So this makes this dead code that hasn't work for a long time. In conclusion, just remove these extra quirks and simplify the setup of the inquiry mode to be inline and with that a lot easier to read and understand.

2015-01-02Bluetooth: Fix SMP channel registration for unconfigured controllersMarcel Holtmann
When the Bluetooth controllers requires an unconfigured state (for example when the BD_ADDR is missing), then it is important to try to register the SMP channels when the controller transitions to the configured state.

2015-01-02Bluetooth: Fix scope of sc_only_mode debugfs entryMarcel Holtmann
The sc_only_mode debugfs entry is used to read the current state of the Secure Connections Only mode. Before Bluetooth 4.2 this mode was only for BR/EDR controllers and with that tight to the support Secure Simple Pairing. Since Secure Connections is now available for BR/EDR and LE this debugfs entry is no longer correctly place. Move it to the common section and enable it when either BR/EDR Secure Connections feature is supported or when the controller has LE support.

2015-01-02Bluetooth: Remove broken force_lesc_support debugfs optionMarcel Holtmann
The force_lesc_support debugfs option never really worked. It has a race condition between creating the debugfs entry and registering the L2CAP fixed channel for BR/EDR SMP support.

2015-01-02Bluetooth: Introduce force_bredr_smp debugfs option for testingMarcel Holtmann
Testing cross-transport pairing that starts on BR/EDR is only valid when using a controller with BR/EDR Secure Connections. Devices will indicate this by providing BR/EDR SMP fixed channel over L2CAP. To allow testing of this feature on Bluetooth 4.0 controller or controllers without the BR/EDR Secure Connections features, introduce a force_bredr_smp debugfs option that allows faking the required AES connection.
