2011-12-23Revert "Bluetooth: Increase HCI reset timeout in hci_dev_do_close"Gustavo F. Padovan
This reverts commit e1b6eb3ccb0c2a34302a9fd87dd15d7b86337f23. This was causing a delay of 10 seconds in the resume process of a Thinkpad laptop. I'm afraid this could affect more devices once 3.2 is released. Reported-by: Tomáš Janoušek <tomi@nomi.cz> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-10-31Bluetooth: Increase HCI reset timeout in hci_dev_do_closeSzymon Janc
I've noticed that my CSR usb dongle was not working if it was plugged in when PC was booting. It looks like I get two HCI reset command complete events (see hcidump logs below). The root cause is reset called from off_timer. Timeout for this reset to complete is set to 250ms and my bt dongle requires more time for replying with command complete event. After that, chip seems to reply with reset command complete event for next non-reset command. Attached patch increase mentioned timeout to HCI_INIT_TIMEOUT, this value is already used for timeouting hci_reset_req in hci_dev_reset(). This might also be related to BT not working after suspend that was reported here some time ago.

2011-09-21Bluetooth: Add mgmt events for blacklistingAntti Julku
Add management interface events for blocking/unblocking a device. Sender of the block device command gets cmd complete and other mgmt sockets get the event. Event is also sent to mgmt sockets when blocking is done with ioctl, e.g when blocking a device with hciconfig. This makes it possible for bluetoothd to track status of blocked devices when a third party block or unblocks a device. Event sending is handled in mgmt_device_blocked function which gets called from hci_blacklist_add in hci_core.c. A pending command is added in mgmt_block_device, so that it can found when sending the event - the event is not sent to the socket from which the pending command came. Locks were moved out from hci_core.c to hci_sock.c and mgmt.c, because locking is needed also for mgmt_pending_add in mgmt.c.

2011-08-11Bluetooth: Don't use cmd_timer to timeout HCI reset commandSzymon Janc
No command should be send before Command Complete event for HCI reset is received. This fix regression introduced by commit 6bd32326cda(Bluetooth: Use proper timer for hci command timout) for chips whose reset command takes longer to complete (e.g. CSR) resulting in next command being send before HCI reset completed.

2011-07-08Bluetooth: Add support for storing the key sizeVinicius Costa Gomes
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.

2011-07-07Bluetooth: Fix potential deadlock in hci_coreAndre Guedes
Since hdev->lock may be acquired by threads runnning in interrupt context, all threads running in process context should disable local bottom halve before locking hdev->lock.

2011-06-08Bluetooth: Add BT_POWER L2CAP socket option.Jaikumar Ganesh
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.
