| * Bluetooth: cancel power_on work when unregistering the deviceGustavo Padovan2013-01-111-0/+2

We need to cancel the hci_power_on work in order to avoid it run when we try to free the hdev.

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...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases it will be useful having the key size used for encrypting the link. For example, some profiles may restrict some operations depending on the key length. The key size is stored in the key that is passed to userspace using the pin_length field in the key structure. For now this field is only valid for LE controllers. 3.0+HS controllers define the Read Encryption Key Size command, this field is intended for storing the value returned by that command.

* | Bluetooth: Add BT_POWER L2CAP socket option.Jaikumar Ganesh2011-07-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add BT_POWER socket option used to control the power characteristics of the underlying ACL link. When the remote end has put the link in sniff mode and the host stack wants to send data we need need to explicitly exit sniff mode to work well with certain devices (For example, A2DP on Plantronics Voyager 855). However, this causes problems with HID devices. Hence, moving into active mode when sending data, irrespective of who set the sniff mode has been made as a socket option. By default, we will move into active mode. HID devices can set the L2CAP socket option to prevent this from happening. Currently, this has been implemented for L2CAP sockets. This has been tested with incoming and outgoing L2CAP sockets for HID and A2DP. Based on discussions on linux-bluetooth and patches submitted by Andrei Emeltchenko.

Removing the timer unconditionally fixes the problem. And yes, it needs to be fixed before the HCI_UP check.

* Bluetooth: Use proper timer for hci command timoutVille Tervo2011-02-161-6/+16
| | | | | | | | | | | | | | | | Use proper timer instead of hci command flow control to timeout failed hci commands. Otherwise stack ends up sending commands when flow control is used to block new commands. 2010-09-01 18:29:41.592132 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 bdaddr 00:16:CF:E1:C7:D7 mode 2 clkoffset 0x0000 2010-09-01 18:29:41.592681 > HCI Event: Command Status (0x0f) plen 4 Remote Name Request (0x01|0x0019) status 0x00 ncmd 0 2010-09-01 18:29:51.022033 < HCI Command: Remote Name Request Cancel (0x01|0x001a) plen 6 bdaddr 00:16:CF:E1:C7:D7 Signed-off-by: Ville Tervo <ville.tervo@nokia.com> Signed-off-by: Gustavo F.
