2012-03-28Bluetooth: hci_core: fix NULL-pointer dereference at unregisterJohan Hovold1-0/+1
Make sure hci_dev_open returns immediately if hci_dev_unregister has been called. This fixes a race between hci_dev_open and hci_dev_unregister which can lead to a NULL-pointer dereference. Bug is 100% reproducible using hciattach and a disconnected serial port: 0. # hciattach -n /dev/ttyO1 any noflow 1. hci_dev_open called from hci_power_on grabs req lock 2. hci_init_req executes but device fails to initialise (times out eventually) 3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock 4. hci_uart_tty_close calls hci_dev_unregister and sleeps on req lock in hci_dev_do_close 5. hci_dev_open (1) releases req lock 6. hci_dev_do_close grabs req lock and returns as device is not up 7. hci_dev_unregister sleeps in destroy_workqueue 8. hci_dev_open (3) grabs req lock, calls hci_init_req and eventually sleeps 9. hci_dev_unregister finishes, while hci_dev_open is still running...

2012-02-24Bluetooth: mgmt: Track pending class changesJohan Hedberg1-0/+1
This patch adds a flag to track pending changes to the class of device. This is needed since we cannot cleanly handle multiple simultaneous commands and need to return a "busy" error status in the mgmt commands that might trigger a class change.

2012-02-23Bluetooth: mgmt: Implement Set LE commandJohan Hedberg1-0/+1
This patch implements support for the Set LE mgmt command. Now, in addition to the enable_le module parameter user space needs to send an explicit Enable LE command to enable LE support. Signed-off-by: Johan Hedberg <[email protected]> Acked-by: Marcel Holtmann <[email protected]>
2012-02-23Bluetooth: mgmt: Make Set Link Security callable while powered offJohan Hedberg1-0/+1
This patch makes it possible to change the Link Security setting while powered off and have it automatically enabled when powering on a device. To track the desired state once powered on a new HCI_LINK_SECURITY flag is added. Signed-off-by: Johan Hedberg <[email protected]> Acked-by: Marcel Holtmann <[email protected]>
2012-02-21Bluetooth: mgmt: Allow connectable/discoverable changes in off stateJohan Hedberg1-0/+2
This patch makes it possible to toggle the connectable & discoverable settings when powered off. Two new hdev->dev_flags flags are added to track what the scan mode should be when the device is finally powered on.

2012-02-21Bluetooth: mgmt: Add basic support for Set High Speed commandJohan Hedberg1-0/+1

2012-02-20Bluetooth: Set supported settings based on enabled HS and/or LEMarcel Holtmann1-0/+1

2012-02-20Bluetooth: Add support for HCI monitor channelMarcel Holtmann1-0/+1

The monitor is not bound to any specific HCI device and allows even capturing multiple devices at the same time.

2012-02-13Bluetooth: Clean up structures left unusedVinicius Costa Gomes1-4/+0
With the use of the new structures and lists for the SMP LTK's we may remove some code that is now unused.

2012-02-13Bluetooth: Add new structures for handling SMP Long Term KeysVinicius Costa Gomes1-0/+5
This includes a new list for storing the keys and a new structure used to represent each key. Some notes: authenticated is used to identify that the key may be used to setup a HIGH security link. As the same list is used to store both the STK's and the LTK's the type field is used so we can separate between those two types of keys and if the key should be used when in the master or slave role.

2012-02-13Bluetooth: Convert hdev->ssp_mode to a flagJohan Hedberg1-0/+1

2012-02-13Bluetooth: Move Extended Inquiry Response defines to hci.hJohan Hedberg1-0/+13
The EIR defines are needed also outside of mgmt.c (e.g. in hci_event.c to check if EIR data has the complete name) so it's better to have them in a single public place, i.e. hci.h. Signed-off-by: Johan Hedberg <[email protected]> Acked-by: Marcel Holtmann <[email protected]>

2011-12-02Bluetooth: Add dev_flags to struct hci_devAndre Guedes1-0/+8
This patch adds the dev_flags field to struct hci_dev. This new flags variable should be used to define flags related to BR/EDR and/or LE controller itself. It should be used to define flags which represents states from the controller. The dev_flags is cleared in case the controller sends a Reset Command Complete Event to the host. Also, this patch adds the HCI_LE_SCAN flag which was created to track if the controller is performing LE scan or not. The flag is set/cleared when the controller starts/stops scanning. This is an initial effort to stop using hdev->flags to define internal flags since it is exported to userspace by an ioctl.

2011-03-31Bluetooth: Add local Extended Inquiry Response (EIR) supportJohan Hedberg1-0/+8
This patch adds automated creation of the local EIR data based on what 16-bit UUIDs are registered and what the device name is. This should cover the majority use cases, however things like 32/128-bit UUIDs, TX power and Device ID will need to be added later to be on par with what bluetoothd is capable of doing (without the Management interface).
