* Bluetooth: Move eir_get_length() function into hci_event.cMarcel Holtmann2013-10-151-17/+0
| | | | | | | | | The eir_get_length() function is only used from hci_event.c and so instead of having a public function move it to the location where it is used. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

* Bluetooth: Add HCI command structure for writing current IAC LAPMarcel Holtmann2013-10-151-0/+6
| | | | | | | | | | | This patch just adds the HCI command structure for configuring the current IAC LAP setting. The length of the command is variable and supports more than two IAC. However since there is only general discoverable and limited discoverable modes, this can be limited to two possible IACs.

* Bluetooth: Update advertising data based on management commandsMarcel Holtmann2013-10-151-2/+0
| | | | | | | | | | | | | | 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.

* Bluetooth: Introduce L2CAP channel callback for resumingMarcel Holtmann2013-10-141-0/+1
| | | | | | | | | Clearing the BT_SK_SUSPEND socket flag from the L2CAP core is causing a dependency on the socket. So intead of doing that, use a channel callback into the socket handling to resume.

* Bluetooth: Introduce L2CAP channel flag for defer setupMarcel Holtmann2013-10-141-0/+1
| | | | | | | | | | | | The L2CAP core should not look into the socket flags to figure out the setting of defer setup. So introduce a L2CAP channel flag that mirrors the socket flag. Since the defer setup option is only set in one place this becomes a really easy thing to do.

* Bluetooth: Provide msg_name callback for L2CAP connectionless channelsMarcel Holtmann2013-10-131-0/+2
| | | | | | | | | | | | | The L2CAP connectionless channels use SOCK_DGRAM and recvmsg() and need to receive the remote BD_ADDR and PSM information via msg_name from the recvmsg() system call. So in case the L2CAP socket is for connectionless channels, provide a msg_name callback that can update the data. Also store the remote BD_ADDR and PSM in the skb so it can be extracted later on.

* Bluetooth: Add support for per socket msg_name callbackMarcel Holtmann2013-10-131-0/+1
| | | | | | | | | | | This allows to add a per socket msg_name callback that can be used for updating the msg_name information for recvmsg() system calls. This feature is used by another patch to support address information on L2CAP connectionless channels.

* Bluetooth: Remove src and dst fields from bt_sock structureMarcel Holtmann2013-10-131-2/+0

* Bluetooth: Store RFCOMM address information in its own socket structureMarcel Holtmann2013-10-131-0/+2

* Bluetooth: Use SCO addresses from HCI connection directlyMarcel Holtmann2013-10-131-3/+0
| | | | | | | | | Instead of storing a pointer to the addresses for the HCI device and HCI connection, use them directly.

* Bluetooth: Return the correct address type for L2CAP socketsMarcel Holtmann2013-10-131-2/+3
| | | | | | | | | | | | | | | | | | The L2CAP sockets can use BR/EDR public, LE public and LE random addresses for various combinations of source and destination devices. So make sure that getsockname(), getpeername() and accept() return the correct address type. For this the address type of the source and destination is stored with the L2CAP channel information. The stored address type is not the one specific for the HCI protocol. It is the address type used for the L2CAP sockets and the management interface. The underlying HCI connections store the HCI address type. If needed, it gets converted to the socket address type.

* Bluetooth: Store address information in L2CAP channel structureMarcel Holtmann2013-10-131-0/+2
| | | | | | | | | | | | | | With the effort of abstracting the L2CAP socket from the underlying L2CAP channel it is important to store the source and destination address information directly in the L2CAP channel structure. Direct access to the HCI connection address information is not possible since they might not be avaiable at L2CAP channel creation time. The address information will be updated when the underlying BR/EDR or LE connection status changes.

* Bluetooth: Store source address of HCI connectionsMarcel Holtmann2013-10-131-0/+1
| | | | | | | | | | | | | The source addressed was based on the public address of the HCI device, but with LE connections this not always the case. For example single mode LE-only controllers would use a static random address. And this address is configured by userspace. To not complicate the lookup of what kind of address is in use, store the correct source address for each HCI connection.

* Bluetooth: Store the source address type of LE connectionsMarcel Holtmann2013-10-131-0/+1
| | | | | | | | | | When establishing LE connections, it is possible to use a public address (if available) or a random address. The type of address is only known when creating connections, so make sure it is stored in hci_conn structure.

* Bluetooth: Remove pointless bdaddr_to_le() helper functionMarcel Holtmann2013-10-131-2/+0
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | The PSM 0x0021 is dedicated to the 3D profile and has permission to use security mode 4 level 0 for L2CAP connectionless unicast data transfers. When establishing a L2CAP connectionless channel on PSM 0x0021, it will no longer force Secure Simple Pairing.

* Bluetooth: Add management command for setting LE scan parametersMarcel Holtmann2013-10-111-0/+7
| | | | | | | | | | | | | | | | | | | | | The scan interval and window parameters are used for LE passive background scanning and connection establishment. This allows userspace to change the values. These two values should be kept in sync with whatever is used for the scan parameters service on remote devices. And it puts the controlling daemon (for example bluetoothd) in charge of setting the values. Main use case would be to switch between two sets of values. One for foreground applications and one for background applications. At this moment, the values are only used for manual connection establishment, but soon that should be extended to background scanning and automatic connection establishment.

* Bluetooth: Make LE scan interval and window a controller optionMarcel Holtmann2013-10-111-0/+2
| | | | | | | | | | | | | The scan interval and window for LE passive scanning and connection establishment should be configurable on a per controller basis. So introduce a setting that later on will allow modifying it. This setting does not affect LE active scanning during device discovery phase. As long as that phase uses interleaved discovery, it will continuously scan. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Add hdev parameter to hdev->send driver callbackMarcel Holtmann2013-10-111-1/+1
| | | | | | | | | | | | | | Instead of masking hdev inside the skb->dev parameter, hand it directly to the driver as a parameter to hdev->send. This makes the driver interface more clear and simpler. This patch fixes all drivers to accept and handle the new parameter of hdev->send callback. Special care has been taken for bpa10x and btusb drivers that require having skb->dev set to hdev for the URB transmit complete handlers.
