usb: musb: host: fix potential NULL pointer dereference

2018-05-23T01:36:40+00:00

[ Upstream commit 2b63f1329df2cd814c1f8353fae4853ace6521d1 ]

musb_start_urb() doesn't check the pass-in parameter if it is NULL.  But
in musb_bulk_nak_timeout() the parameter passed to musb_start_urb() is
returned from first_qh(), which could be NULL.

So wrap the musb_start_urb() call here with a if condition check to
avoid the potential NULL pointer dereference.

USB: serial: visor: handle potential invalid device configuration

2018-05-23T01:36:40+00:00

[ Upstream commit 4842ed5bfcb9daf6660537d70503c18d38dbdbb8 ]

If we get an invalid device configuration from a palm 3 type device, we
might incorrectly parse things, and we have the potential to crash in
"interesting" ways.

Fix this up by verifying the size of the configuration passed to us by
the device, and only if it is correct, will we handle it.

Note that this also fixes an information leak of slab data.

USB: Increment wakeup count on remote wakeup.

2018-05-23T01:36:37+00:00

[ Upstream commit 83a62c51ba7b3c0bf45150c4eac7aefc6c785e94 ]

On chromebooks we depend on wakeup count to identify the wakeup source.
But currently USB devices do not increment the wakeup count when they
trigger the remote wake. This patch addresses the same.

Resume condition is reported differently on USB 2.0 and USB 3.0 devices.

On USB 2.0 devices, a wake capable device, if wake enabled, drives
resume signal to indicate a remote wake (USB 2.0 spec section 7.1.7.7).
The upstream facing port then sets C_PORT_SUSPEND bit and reports a
port change event (USB 2.0 spec section 11.24.2.7.2.3). Thus if a port
has resumed before driving the resume signal from the host and
C_PORT_SUSPEND is set, then the device attached to the given port might
be the reason for the last system wakeup. Increment the wakeup count for
the same.

On USB 3.0 devices, a function may signal that it wants to exit from device
suspend by sending a Function Wake Device Notification to the host (USB3.0
spec section 8.5.6.4) Thus on receiving the Function Wake, increment the
wakeup count.

USB: serial: ftdi_sio: use jtag quirk for Arrow USB Blaster

2018-05-23T01:36:37+00:00

[ Upstream commit 470b5d6f0cf4674be2d1ec94e54283a1770b6a1a ]

Arrow USB Blaster integrated on MAX1000 board uses the same vendor ID
(0x0403) and product ID (0x6010) as the "original" FTDI device.

This patch avoids picking up by ftdi_sio of the first interface of this
USB device. After that this device can be used by Arrow user-space JTAG
driver.
