| * Input: hyper-v - fix wakeup from suspend-to-idleVitaly Kuznetsov2018-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It makes little sense but still possible to put Hyper-V guests into suspend-to-idle state. To wake them up two wakeup sources were registered in the past: hyperv-keyboard and hid-hyperv. However, since commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch to pm_wakeup_hard_event() API as these devices are actually the only possible way to wakeup Hyper-V guests.

This commit adds a new is_signed parameter to the function and makes all callers pass the appropriate value for this. While at it, this commit also fixes up some neighboring lines where statements were needlessly split over 2 lines to improve readability.

The device in question stops working after receives SLEEP, ON, SLEEP commands in a short period. The scenario is like this: - Once the desktop session closes, it also closed the hid device, so the device gets runtime suspended and receives a SLEEP command. - Before calling shutdown callback, it gets runtime resumed and received an ON command. - In the shutdown callback, it receives another SLEEP command. I failed to find a reliable interval between ON/SLEEP commands that can make it work, so let's simply disable runtime PM for the device.

While it worked mostly fine, some games got confused by the idle gamepad, and switched to two player mode, or asked the user to choose which gamepad to use. Other games just crashed, probably a bug in Unity [1]. With this commit, when a HID client starts, the input device is removed; when the HID client ends the input device is recreated.

Please note that `strlcpy()` does *NOT* do what you think it does. strlcpy() *ALWAYS* reads the full input string, regardless of the 'length' parameter. That is, if the input is not zero-terminated, strlcpy() will *READ* beyond input boundaries. It does this, because it always returns the size it *would* copy if the target was big enough, not the truncated size it actually copied. The original code was perfectly fine. The hid device is zero-initialized and the strncpy() functions copied up to n-1 characters. The result is always zero-terminated this way. This is the third time someone tried to replace strncpy with strlcpy in this function, and gets it wrong. I now added a comment that should at least make people reconsider.

* | | | HID: uhid: forbid UHID_CREATE under KERNEL_DS or elevated privilegesEric Biggers2018-11-191-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a UHID_CREATE command is written to the uhid char device, a copy_from_user() is done from a user pointer embedded in the command. When the address limit is KERNEL_DS, e.g. as is the case during sys_sendfile(), this can read from kernel memory. Alternatively, information can be leaked from a setuid binary that is tricked to write to the file descriptor. Therefore, forbid UHID_CREATE in these cases. No other commands in uhid_char_write() are affected by this bug and UHID_CREATE is marked as "obsolete", so apply the restriction to UHID_CREATE only rather than to uhid_char_write() entirely. Thanks to Dmitry Vyukov for adding uhid definitions to syzkaller and to Jann Horn for commit 9da3f2b740544 ("x86/fault: BUG() when uaccess helpers fault on kernel addresses"), allowing this bug to be found.

However, in this model, the keybard backlight control exposed by hid-asus has no effect on the keyboard backlight. Instead, the keyboard backlight is correctly driven by asus-wmi. With two keyboard backlight devices available (and only the acer-wmi one working), GNOME is picking the wrong one to drive in the UI. Avoid this problem by not creating the backlight interface when we detect a WMI-driven keyboard backlight. We have also tested Asus GL702VMK which does have the hid-asus backlight present, and it still works fine with this patch (WMI method call returns UNSUPPORTED_METHOD). A direct "depends on ASUS_WMI" is intentionally avoided so that HID_ASUS users who have ASUS_WMI=n will not quietly lose their HID_ASUS driver on a kernel upgrade.

But the resulting algorithm was unstable, and causes scrolling to be very unreliable. When you hit the half-way mark of the highres multiplier, small highres movements will incorrectly translate into big traditional wheel movements, causing odd jitters. Simplify the code and make the output stable. NOTE! I'm pretty sure this will need further tweaking. But this at least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into a usable one.

The only reason something should be 'default y' is if it used to be built-in, and it was made configurable, and the 'default y' is just retaining the status quo. Altheratively, the hardware for the driver has become _so_ common that it really makes sense for everybody to build it. Finally, one possible reason for 'default y' is because the option is not enabling any new code at all, but is just enabling other options (the networking people do this for vendor options, for example, so that you can disable whole vendors at a time). Clearly, none of these cases hold for the BigBen Interactive Kids' gamepad, and HID_BIGBEN_FF should thus most definitely not default to on for everybody.

But the table wasn't properly terminated, causing the dmi matching to walk off into la-la-land, and starting to treat random data as dmi descriptor pointers, causing boot-time oopses if you were at all unlucky. Terminate the array. We really should have some way to just statically check that arrays that should be terminated by an empty entry actually are so. But the HID people really should have caught this themselves, rather than have me deal with an oops during the merge window. Tssk, tssk.

It turns out that a later model Laurent got doesn't need the quirk after all. My take is that Eaton upgraded their firmwares, so we don't need it anymore. The old model was from 2012, so better make sure the new line works properly by removing the quirk. This allows upower to actually fetch the current data.

During user logging, the display manager exits, close the HID device, then the device gets runtime suspended and powered off. The desktop session begins shortly after, opens the HID device, then the device gets runtime resumed and powered on. If the trasition from display manager to desktop sesesion is fast, the touchpanel cannot switch from powered off to powered on in short timeframe. So add a small delay to workaround the issue.

This field is used as an array index by the hiddev_ioctl_usage() function, when 'cmd' is either HIDIOCGCOLLECTIONINDEX, HIDIOCGUSAGES or HIDIOCSUSAGES. For cmd == HIDIOCGCOLLECTIONINDEX case, uref->usage_index is compared to field->maxusage and then used as an index to dereference field->usage array. The same thing happens to the cmd == HIDIOC{G,S}USAGES cases, where uref->usage_index is checked against an array maximum value and then it is used as an index in an array. This is a summary of the HIDIOCGCOLLECTIONINDEX case, which matches the traditional Spectre V1 first load: copy_from_user(uref, user_arg, sizeof(*uref)) if (uref->usage_index >= field->maxusage) goto inval; i = field->usage[uref->usage_index].collection_index; return i; This patch fixes this by sanitizing field uref->usage_index before using it to index field->usage (HIDIOCGCOLLECTIONINDEX) or field->value in HIDIOC{G,S}USAGES arrays, thus, avoiding speculation in the first load.
