USB: option: add support for DW5821e

2018-08-22T05:44:54+00:00

commit 7bab01ecc6c43da882333c6db39741cb43677004 upstream. The device exposes AT, NMEA and DIAG ports in both USB configurations. The patch explicitly ignores interfaces 0 and 1, as they're bound to other drivers already; and also interface 6, which is a GNSS interface for which we don't have a driver yet.

USB: serial: sierra: fix potential deadlock at close

2018-08-22T05:44:54+00:00

commit e60870012e5a35b1506d7b376fddfb30e9da0b27 upstream. The portdata spinlock can be taken in interrupt context (via sierra_outdat_callback()). Disable interrupts when taking the portdata spinlock when discarding deferred URBs during close to prevent a possible deadlock.

USB: serial: mos7840: fix status-register error handling

commit 794744abfffef8b1f3c0c8a4896177d6d13d653d upstream. Add missing transfer-length sanity check to the status-register completion handler to avoid leaking bits of uninitialised slab data to user space.

commit 367b160fe4717c14a2a978b6f9ffb75a7762d3ed upstream. There are two versions of the Qivicon Zigbee stick in circulation. This adds the second USB ID to the cp210x driver. Signed-off-by: Olli Salonen Cc: stable Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: ch341: fix type promotion bug in ch341_control_in()

2018-07-17T09:48:26+00:00

commit e33eab9ded328ccc14308afa51b5be7cbe78d30b upstream. The "r" variable is an int and "bufsize" is an unsigned int so the comparison is type promoted to unsigned. If usb_control_msg() returns a negative that is treated as a high positive value and the error handling doesn't work.

USB: serial: cp210x: add Silicon Labs IDs for Windows Update

2018-07-08T13:32:16+00:00

commit 2f839823382748664b643daa73f41ee0cc01ced6 upstream. Silicon Labs defines alternative VID/PID pairs for some chips that when used will automatically install drivers for Windows users without manual intervention. Unfortunately, these IDs are not recognized by the Linux module, so using these IDs improves user experience on one platform but degrades it on Linux. This patch addresses this problem.

USB: serial: visor: handle potential invalid device configuration

2018-05-02T07:37:19+00:00

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.
