2018-07-06USB: yurex: fix out-of-bounds uaccess in read handlerJann Horn
In general, accessing userspace memory beyond the length of the supplied buffer in VFS read/write handlers can lead to both kernel memory corruption (via kernel_read()/kernel_write(), which can e.g. be triggered via sys_splice()) and privilege escalation inside userspace. Fix it by using simple_read_from_buffer() instead of custom logic.

2018-07-06usb: quirks: add delay quirks for Corsair StrafeNico Sneck
Corsair Strafe appears to suffer from the same issues as the Corsair Strafe RGB. Apply the same quirks (control message delay and init delay) that the RGB version has to 1b1c:1b15. With these quirks in place the keyboard works correctly upon booting the system, and no longer requires reattaching the device.

When the hangcheck handler was replaced by the DRM scheduler timeout handling we dropped the forward progress check, as this might allow clients to hog the GPU for a long time with a big job. It turns out that even reasonably well behaved clients like the Armada Xorg driver occasionally trip over the 500ms timeout. Bring back the forward progress check to get rid of the userspace regression. We would still like to fix userspace to submit smaller batches if possible, but that is for another day.

2018-07-05drm/udl: fix display corruption of the last lineMikulas Patocka
The displaylink hardware has such a peculiarity that it doesn't render a command until next command is received. This produces occasional corruption, such as when setting 22x11 font on the console, only the first line of the cursor will be blinking if the cursor is located at some specific columns. When we end up with a repeating pixel, the driver has a bug that it leaves one uninitialized byte after the command (and this byte is enough to flush the command and render it - thus it fixes the screen corruption), however whe we end up with a non-repeating pixel, there is no byte appended and this results in temporary screen corruption. This patch fixes the screen corruption by always appending a byte 0xAF at the end of URB. It also removes the uninitialized byte.

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.

2018-07-04ACPI / battery: Safe unregistering of hooksJouke Witteveen
A hooking API was implemented for 4.17 in fa93854f7a7ed63d followed by hooks for Thinkpad laptops in 2801b9683f740012. The Thinkpad drivers did not support the Thinkpad 13 and the hooking API crashes on unsupported batteries by altering a list of hooks during unsafe iteration. Thus, Thinkpad 13 laptops could no longer boot. Additionally, a lock was kept in place and debugging information was printed out of order.

2018-07-04drm/amdgpu: fix user fence write race conditionNicolai Hähnle
The buffer object backing the user fence is reserved using the non-user fence, i.e., as soon as the non-user fence is signaled, the user fence buffer object can be moved or even destroyed. Therefore, emit the user fence first. Both fences have the same cache invalidation behavior, so this should have no user-visible effect.

NetworkManager likes to manage linklocal prefix routes and does so with the NLM_F_APPEND flag, breaking attempts to simplify the IPv6 route code and by extension enable multipath routes with device only nexthops.

The conversion from offsetof() calculations to sizeof() wrongly behaved for missed exact size and in scenario with more than one flow. In such scenario we got "create flow failed, flow 10: 8 bytes left from uverb cmd" error, which is wrong because the size of kern_spec is exactly 8 bytes, and we were not supposed to fail.

2018-07-03PM / Domains: Don't power on at attach for the multi PM domain caseUlf Hansson
There are no legacy behavior in drivers to consider while attaching a device to genpd - for the multiple PM domain case. For that reason, let's instead require the driver to runtime resume the device, via calling pm_runtime_get_sync() for example, when it needs to power on the corresponding PM domain. This allows us to improve the situation during attach. Instead of always power on the PM domain, which may be unnecessary, let's leave it in its current state. Additionally, to avoid the PM domain to stay powered on, let's schedule a power off work. Fixes: 3c095f32a92b (PM / Domains: Add support for multi PM domains ...)
