2014-07-31Bluetooth: Fix crash in the Marvell driver initialization codepathAnatol Pomozov1-0/+5
btmrvl_add_card() function calls kthread_run that might return error (e.g. if current thread is killed). If one tries to use the error value as a pointer then invalid memory access oops happens. Check kthread_run() return value, if it is an error then release resources correctly. TEST=boot computer with BT modules enabled. I see the error message that BT device initialization failed. Now kernel does not crash. Hint: to enable BT run 'rmmod btmrvl_sdio; modprobe btmrvl_sdio' Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2014-07-20Bluetooth: Fix endian and alignment issue with ath3k version handlingMarcel Holtmann1-13/+16
The ath3k driver is treating the version information badly when it comes to loading the right firmware version and comparing that it actually matches with the hardware.

2014-07-15Bluetooth: btmrvl: avoid sending data to firmware after hs_activatedChin-Ran Lo1-8/+8
We should suspend hci device and purge remaining data in tx queue before enabling host sleep in firmware. If any data is sent to firmware after host sleep is activated, firmware may end up sending a TX_DONE interrupt to driver. If this interrupt gets delivered to host while the SDIO host controller is suspending, it may crash the system. Conversely, in resume handler, we should resume hci device after host sleep is de-activated.

2014-05-09Bluetooth: btusb: Add Broadcom patch RAM supportPetri Gynther1-1/+154
After hardware reset, some BCM Bluetooth adapters obtain their initial firmware from OTPROM chip. Once this initial firmware is running, the firmware can be further upgraded over HCI interface with .hcd files provided by Broadcom. This is also known as "patch RAM" support. This change implements that. If the .hcd file is not found in /lib/firmware, BCM Bluetooth adapter continues to operate with the initial firmware. Sample kernel log: hotplug: sys=firmware act=add fw=brcm/BCM20702A0-0a5c-22be.hcd dev=... Bluetooth: hci0: BCM: patch brcm/BCM20702A0-0a5c-22be.hcd not found If the .hcd file is found, btusb driver pushes it to the BCM Bluetooth adapter and it starts using the new firmware. Sample kernel log: hotplug: sys=firmware act=add fw=brcm/BCM20702A0-0a5c-22be.hcd dev=...

2014-04-25Revert "Bluetooth: Enable autosuspend for Intel Bluetooth device"Marcel Holtmann1-3/+1
This reverts commit d2bee8fb6e18f6116aada39851918473761f7ab1. Enabling autosuspend for Intel Bluetooth devices has been shown to not work reliable. It does work for some people with certain combinations of USB host controllers, but for others it puts the device to sleep and it will not wake up for any event. These events can be important ones like HCI Inquiry Complete or HCI Connection Request. The events will arrive as soon as you poke the device with a new command, but that is not something we can do in these cases. Initially there were patches to the xHCI USB controller that fixed this for some people, but not for all. This could be well a problem somewhere in the USB subsystem or in the USB host controllers or just plain a hardware issue somewhere. At this moment we just do not know and the only safe action is to revert this patch.
