2013-10-11Bluetooth: Make LE scan interval and window a controller optionMarcel Holtmann
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.

2013-10-11Bluetooth: Add hdev parameter to hdev->send driver callbackMarcel Holtmann
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.

2013-10-11Bluetooth: Provide hdev parameter to hci_recv_frame() driver callbackMarcel Holtmann
To avoid casting skb->dev into hdev, just let the drivers provide the hdev directly when calling hci_recv_frame() function. This patch also fixes up all drivers to provide the hdev. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2013-10-11Bluetooth: Remove return value from hci_send_frame() functionMarcel Holtmann
The return value of hci_send_frame() is never checked. So just make this function void and print an error when the hdev->send driver callback returns a negative value. Having the error printed is actually an improvement over the current situation where any driver error just gets ignored.

2013-10-11Bluetooth: Remove pointless check of hci_send_frame parameterMarcel Holtmann
The hdev parameter of hci_send_frame must be always valid. If the hdev is not valid, it would not even make it to this stage. The callers will have already accessed hdev at that point many times.

2013-10-11Bluetooth: Move skb->dev assignment for hdev->send into central placeMarcel Holtmann
The assignement of skb->dev is done all over the place. So it makes it hard to eventually get rid of it. Move it all in one central place so it gets assigned right before calling hdev->send driver callback.

2013-10-10Bluetooth: AMP contollers do not support the legacy ioctlsMarcel Holtmann
The legacy ioctls for device specific commands including inquiry are not support by AMP controllers.

2013-10-10Bluetooth: Use hci_conn_num() instead of direct connection hash accessMarcel Holtmann
When changing the alternate setting for the ISOC endpoints, use the hci_conn_num() helper function to count currently established SCO and eSCO connections and store the the value. This avoids direct access to the connection hash. In addition use the stored value instead accessing the connection hash over and over again.

2013-10-10Bluetooth: Use hci_conn_num() for checking number of LE connectionsMarcel Holtmann
When checking for the current number of LE connections, use hci_conn_num() function instead of a full blown lookup within the connection hash or direct access of the counters. In the case of re-enabling advertising, it is more useful to check for any connection attempt or existing connection.

2013-10-10Bluetooth: Fix checking for HCI_SETUP flag when receiving mgmt commandsJohan Hedberg
When the HCI_SETUP flag is set the controller has not yet been announced over mgmt and therefore doesn't exist from that perspective.

2013-10-10Bluetooth: Fix potential double-frees of L2CAP skbsJohan Hedberg
The l2cap_recv_frame function is expected to take ownership and eventually free the skb passed to it. We need to ensure that the conn->rx_skb pointer is no longer reachable when calling l2cap_recv_frame so that no other function, such as l2cap_conn_del, may think that it can free conn->rx_skb. An actual situation when this can happen is when smp_sig_channel (called from l2cap_recv_frame) fails and l2cap_conn_del gets called as a consequence. The l2cap_conn_del function would then try to free conn->rx_skb, but as the same skb was just passed to smp_sig_channel and freed we get a double-free.

2013-10-10Bluetooth: Restrict high speed support to SSP enabled controllersMarcel Holtmann
The support for Bluetooth High Speed can only be enabled on controllers where also Secure Simple Pairing has been enabled. Trying to enable high speed when SSP is disabled will result into an error. Disabling SSP will at the same time disable high speed as well. It is required to enforce this dependency on SSP since high speed support is only defined for authenticated, unauthenticated and debug link keys. These link key types require SSP.

2013-10-10Bluetooth: Remove unneeded val variable when setting SSPMarcel Holtmann

2013-10-10Bluetooth: Refactor hci_connect_leAndre Guedes

It also adds extra comments to improve the code readability. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-10Bluetooth: Use HCI request for LE connectionAndre Guedes
This patch introduces a new helper, which uses the HCI request framework, for creating LE connectons. All the handling is now done by this function so we can remove the hci_cs_le_create_conn() event handler. This patch also removes the old hci_le_create_connection() since it is not used anymore.

2013-10-08Bluetooth: Fix changing advertising setting while LE is connectedJohan Hedberg
We only (re)enable advertising when LE is disconnected. Trying to enable advertising using mgmt_set_advertising while connected should simply change the flag but not do anything else (until the connection gets dropped). This patch fixes this by making an LE connection lookup to determine whether there are any connected devices or not.

2013-10-07Bluetooth: Read flow control mode on AMP controller initMarcel Holtmann

2013-10-07Bluetooth: Make mgmt power down notification for BR/EDR explicitMarcel Holtmann
The management interface only operates on BR/EDR controllers. The check for the power down notification is a bit intermixed with the check if controller auto power off is active. Since there are more than just BR/EDR controllers supported, make this check explicit since the auto power off check also applies to AMP controllers and it has to happen in this exact order. Otherwise the bit will not be cleared. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-07Bluetooth: Power off AMP controllers after setup phaseMarcel Holtmann
Even AMP controllers should be powered off after the setup phase. It is not a good idea to keep AMP controllers powered on all the time if they are not in use. Power on of the AMP controller can either be done manually via command line commands or directly via A2MP. Especially since there is an indication in A2MP for powered down controllers that can be activated.
