bluetooth: btusb: Replace GFP_ATOMIC with GFP_KERNEL in inject_cmd_complete()

2018-07-23T16:05:00+00:00

inject_cmd_complete() is only called by btusb_send_frame_intel(), which is set to hdev->send, and hdev->send() is never called in atomic context. inject_cmd_complete() calls bt_skb_alloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. I also manually check the kernel code before reporting it.

Bluetooth: btusb: use irqsave() in URB's complete callback

2018-07-06T10:36:21+00:00

The USB completion callback does not disable interrupts while acquiring the ->lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave variant of the locking primitives.

Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models

2018-05-29T13:59:50+00:00

In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174") we tried to address the non-working Atheros BT devices by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made such devices working while it turned out to break other existing chips with the very same USB ID, hence it was reverted afterwards. This is another attempt to tackle the issue. The essential point to use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM- patching. And the previous attempt failed because btusb_setup_qca() returns -ENODEV if the ROM version doesn't match with the expected ones. For some devices that have already the "correct" ROM versions, we may just skip the setup procedure and continue the rest. So, the first fix we'll need is to add a check of the ROM version in the function to skip the setup if the ROM version looks already sane, so that it can be applied for all ath devices. However, the world is a bit more complex than that simple solution. Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's 0x0001 at the beginning of probing, so the device probe always aborts here. In this patch, we add another check of ROM version again, and if the device needs patching, the probe continues. For that, a slight refactoring of btusb_qca_send_vendor_req() was required so that the probe function can pass usb_device pointer directly before allocating hci_dev stuff.
