2012-09-27Bluetooth: Use %pMR in debug instead of batostrAndrei Emeltchenko

2012-09-27Bluetooth: Force the process of unpair command if disconnect failedJefferson Delfes
The unpair process tries to disconnect any connection pending with remote. If there are some connection in connecting state, disconnect command will fail and unpair mgmt command will stay pending. That pending mgmt command can cause strange behavior like automatic unpair after a lost connection.

2012-09-18Bluetooth: Update management interface revisionJohan Hedberg
For each kernel release where commands or events are added to the management interface, the revision field should be increment by one. The increment should only happen once per kernel release and not for every command/event that gets added. The revision value is for informational purposes only, but this simple policy would make any future debugging a lot simple.

2012-09-18Bluetooth: mgmt: Fix enabling LE while powered offAndrzej Kaczmarek
When new BT USB adapter is plugged in it's configured while still being powered off (HCI_AUTO_OFF flag is set), thus Set LE will only set dev_flags but won't write changes to controller. As a result it's not possible to start device discovery session on LE controller as it uses interleaved discovery which requires LE Supported Host flag in extended features.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem John W. Linville says: ==================== Please pull these fixes intended for 3.6. There are more commits here than I would like -- I got a bit behind while I was stalking Steven Rostedt in San Diego last week... I'll slow it down after this! There are a couple of pulls here. One is from Johannes: "Please pull (according to the below information) to get a few fixes. * a fix to properly disconnect in the driver when authentication or association fails * a fix to prevent invalid information about mesh paths being reported to userspace * a memory leak fix in an nl80211 error path" The other comes via Gustavo: "A few updates for the 3.6 kernel. There are two btusb patches to add more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO() macro and another one that add a new device id for a Sony Vaio laptop, one fix for a user-after-free and, finally, two patches from Vinicius to fix a issue in SMP pairing." Along with those... Arend van Spriel provides a fix for a use-after-free bug in brcmfmac. Daniel Drake avoids a hang by not trying to touch the libertas hardware duing suspend if it is already powered-down. Felix Fietkau provides a batch of ath9k fixes that adress some potential problems with power settings, as well as a fix to avoid a potential interrupt storm. Gertjan van Wingerde provides a register-width fix for rt2x00, and a rt2x00 fix to prevent incorrectly detecting the rfkill status. He also provides a device ID patch. Hante Meuleman gives us three brcmfmac fixes, one that properly initializes a command structure, one that fixes a race condition that could lose usb requests, and one that removes some log spam. Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some specific devices. Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to using timers that aren't allocated when 2 wire bluetooth coexistence hardware is in use. Sergei Poselenov changes rt2800usb to do some validity checking for received packets, avoiding crashes on an ARM Soc. Stone Piao gives us an mwifiex fix for an incorrectly set skb length value for a command buffer. All of these are localized to their specific drivers, and relatively small. The power-related patches from Felix are bigger than I would like, but I merged them in consideration of their isolation to ath9k and the sensitive nature of power settings in wireless devices. ==================== Signed-off-by: David S.

MGMT_EV_DEVICE_DISCONNECTED will now expose the disconnection reason to userland, distinguishing four possible values: 0x00 Reason not known or unspecified 0x01 Connection timeout 0x02 Connection terminated by local host 0x03 Connection terminated by remote host Note that the local/remote distinction just determines which side terminated the low-level connection, regardless of the disconnection of the higher-level profiles. This can sometimes be misleading and thus must be used with care. For example, some hardware combinations would report a locally initiated disconnection even if the user turned Bluetooth off in the remote side.
