2018-11-27T15:09:41Z

commit a77112577667cbda7c6292c52d909636aef31fd9 upstream.

USB: quirks: Add no-lpm quirk for Raydium touchscreens

2018-11-27T15:09:41Z

commit deefd24228a172d1b27d4a9adbfd2cdacd60ae64 upstream. Raydium USB touchscreen fails to set config if LPM is enabled: [ 2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119 [ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2.030660] usb 1-8: Product: Raydium Touch System [ 2.030661] usb 1-8: Manufacturer: Raydium Corporation [ 7.132209] usb 1-8: can't set config #1, error -110 Same behavior can be observed on 2386:3114. Raydium claims the touchscreen supports LPM under Windows, so I used Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows that the LPM doesn't work under Windows, either. So let's just disable LPM for Raydium touchscreens.

usbip:vudc: BUG kmalloc-2048 (Not tainted): Poison overwritten

usb: chipidea: Prevent unbalanced IRQ disable

2018-11-13T19:16:53Z

[ Upstream commit 8b97d73c4d72a2abf58f8e49062a7ee1e5f1334e ] The ChipIdea IRQ is disabled before scheduling the otg work and re-enabled on otg work completion. However if the job is already scheduled we have to undo the effect of disable_irq int order to balance the IRQ disable-depth value.

USB: fix the usbfs flag sanitization for control transfers

2018-11-10T15:43:00Z

commit 665c365a77fbfeabe52694aedf3446d5f2f1ce42 upstream. Commit 7a68d9fb8510 ("USB: usbdevfs: sanitize flags more") checks the transfer flags for URBs submitted from userspace via usbfs. However, the check for whether the USBDEVFS_URB_SHORT_NOT_OK flag should be allowed for a control transfer was added in the wrong place, before the code has properly determined the direction of the control transfer. (Control transfers are special because for them, the direction is set by the bRequestType byte of the Setup packet rather than direction bit of the endpoint address.) This patch moves code which sets up the allow_short flag for control transfers down after is_in has been set to the correct value.

usb: gadget: storage: Fix Spectre v1 vulnerability

2018-11-10T15:43:00Z

commit 9ae24af3669111d418242caec8dd4ebd9ba26860 upstream. num can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/usb/gadget/function/f_mass_storage.c:3177 fsg_lun_make() warn: potential spectre issue 'fsg_opts->common->luns' [r] (local cap) Fix this by sanitizing num before using it to index fsg_opts->common->luns Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

cdc-acm: correct counting of UART states in serial state notification

2018-11-10T15:43:00Z

commit f976d0e5747ca65ccd0fb2a4118b193d70aa1836 upstream. The usb standard ("Universal Serial Bus Class Definitions for Communication Devices") distiguishes between "consistent signals" (DSR, DCD), and "irregular signals" (break, ring, parity error, framing error, overrun). The bits of "irregular signals" are set, if this error/event occurred on the device side and are immeadeatly unset, if the serial state notification was sent. Like other drivers of real serial ports do, just the occurence of those events should be counted in serial_icounter_struct (but no 1->0 transitions).
