usb: quirks: add delay quirks for Corsair Strafe 2018-07-17T09:37:52+00:00 Nico Sneck snecknico@gmail.com 2018-07-02T16:26:07+00:00 cac38ab7d4ff3b97eea76b7a59e22ced0dbb85a6 commit bba57eddadda936c94b5dccf73787cb9e159d0a5 upstream. 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.

commit bba57eddadda936c94b5dccf73787cb9e159d0a5 upstream.

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.

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.

The dwc2_get_ls_map() use ttport to reference into the bitmap if we're on a multi_tt hub. But the bitmaps index from 0 to (hub->maxchild - 1), while the ttport index from 1 to hub->maxchild. This will cause invalid memory access when the number of ttport is hub->maxchild. Without this patch, I can easily meet a Kernel panic issue if connect a low-speed USB mouse with the max port of FE2.1 multi-tt hub (1a40:0201) on rk3288 platform.
