2018-11-20HID: Add quirk for Primax PIXART OEM miceSebastian Parschauer2-0/+4
The PixArt OEM mice are known for disconnecting every minute in runlevel 1 or 3 if they are not always polled. So add quirk ALWAYS_POLL for two Primax mice as well. 0x4e22 is the Dell MS111-P and 0x4d0f is the unbranded HP Portia mouse HP 697738-001. Both were built until approx. 2014.

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.

2018-11-19HID: steam: remove input device when a hid client is running.Rodrigo Rivas Costa1-64/+90
Previously, when a HID client such as the Steam Client was running, this driver disabled its input device to avoid doubling the input events. 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.

2018-11-19Revert "HID: uhid: use strlcpy() instead of strncpy()"David Herrmann1-6/+7
This reverts commit 336fd4f5f25157e9e8bd50e898a1bbcd99eaea46. 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.

2018-11-19HID: uhid: forbid UHID_CREATE under KERNEL_DS or elevated privilegesEric Biggers1-0/+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.

2018-10-31HID: asus: only support backlight when it's not driven by WMIDaniel Drake2-1/+23
The Asus GL502VSK has the same 0B05:1837 keyboard as we've seen in several Republic of Gamers laptops. 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.

2018-10-29HID: input: simplify/fix high-res scroll event handlingLinus Torvalds1-22/+21
Commit 1ff2e1a44e02 ("HID: input: Create a utility class for counting scroll events") created the helper function hid_scroll_counter_handle_scroll() to handle high-res scroll events and also expose them as regular wheel events. 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.

2018-10-27HID: we do not randomly make new drivers 'default y'Linus Torvalds1-1/+0
.. even when that "default y" is hidden syntactically as a default !EXPERT it's wrong. 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.

Commit 9ee3e06610fd ("HID: i2c-hid: override HID descriptors for certain devices") added a new dmi_system_id quirk table to override certain HID report descriptors for some systems that lack them. 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.

2018-10-26HID: hiddev: fix potential Spectre v1Breno Leitao1-4/+14
uref->usage_index can be indirectly controlled by userspace, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. 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.

The DTK-2451 and DTH-2452 have a buggy HID descriptor which incorrectly contains a Cintiq-like report, complete with pen tilt, rotation, twist, serial number, etc. The hardware doesn't actually support this data but our driver duitifully sets up the device as though it does. To ensure userspace has a correct view of devices without updated firmware, we clean up this incorrect data in wacom_setup_device_quirks. We're also careful to clear the WACOM_QUIRK_TOOLSERIAL flag since its presence causes the driver to wait for serial number information (via wacom_wac_pen_serial_enforce) that never comes, resulting in the pen being non-responsive.

This can be done with c99 initializers, which makes the code cleaner and more transparent. It does require gcc 4.6, because of this bug in earlier versions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676 Since commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6"), this is the case.

A particular touchpad (SIPODEV SP1064) refuses to supply the HID descriptors. This patch provides the framework for overriding these descriptors based on DMI data. It also includes the descriptors for said touchpad, which were extracted by listening to the traffic of the windows filter driver, as well as the DMI data for the laptops known to use this device.
