The commit 4097461897df ("Input: i8042 - break load dependency ...") correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do the same for AUX port(s), which results in communication on KBD and AUX ports to clash with each other.

2016-07-27Input: xpad - power off wireless 360 controllers on suspendCameron Gutman1-0/+43
When the USB wireless adapter is suspended, the controllers lose their connection. This causes them to start flashing their LED rings and searching for the wireless adapter again, wasting the controller's battery power. Instead, we will tell the controllers to power down when we suspend. This mirrors the behavior of the controllers when connected to the console itself and how the official Xbox One wireless adapter behaves on Windows.

As explained in [email protected] we have a hard load dependency between i8042 and atkbd which prevents keyboard from working on Gen2 Hyper-V VMs. > hyperv_keyboard invokes serio_interrupt(), which needs a valid serio > driver like atkbd.c. atkbd.c depends on libps2.c because it invokes > ps2_command(). libps2.c depends on i8042.c because it invokes > i8042_check_port_owner(). As a result, hyperv_keyboard actually > depends on i8042.c. > > For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a > Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m > rather than =y, atkbd.ko can't load because i8042.ko can't load(due to > no i8042 device emulated) and finally hyperv_keyboard can't work and > the user can't input: https://bugs.archlinux.org/task/39820 > (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y) To break the dependency we move away from using i8042_check_port_owner() and instead allow serio port owner specify a mutex that clients should use to serialize PS/2 command stream.

2016-07-26Input: cros_ec_keyb - cleanup use of devDouglas Anderson1-10/+9
In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was the EC's dev pointer and not the keyboard's. Let's clean this up to make it the keyboard's dev pointer. This could be useful in future patches but also has the nice effect of changing a few printouts to include the name of the keyboard device instead of the EC device, so we will see: [ 1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14 instead of: [ 1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14 Signed-off-by: Douglas Anderson <[email protected]> Signed-off-by: Brian Norris <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2016-07-20tty/vt/keyboard: fix OOB access in do_compute_shiftstate()Dmitry Torokhov1-21/+9
The size of individual keymap in drivers/tty/vt/keyboard.c is NR_KEYS, which is currently 256, whereas number of keys/buttons in input device (and therefor in key_down) is much larger - KEY_CNT - 768, and that can cause out-of-bound access when we do sym = U(key_maps[0][k]); with large 'k'. To fix it we should not attempt iterating beyond smaller of NR_KEYS and KEY_CNT. Also while at it let's switch to for_each_set_bit() instead of open-coding it.

Currently, the caller is not incrementing the refcount of the of_node which results in the node being prematurely freed when of_find_node_by_name() calls of_node_put() on it.

2016-06-23Input: vmmouse - remove port reservationSinclair Yeh1-20/+2
The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This causes the port to be reserved by the APCI module as the system comes up, making it unavailable to be reserved again by other drivers, thus preserving this VMWare port for special use in a VMWare guest. This port is designed to be shared among multiple VMWare services, such as the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port on its own. The VMWare non-EFI BIOS does not do this to preserve compatibility with existing/legacy VMs. It is known that there is small chance a VM may be configured such that these ports get reserved by other non-VMWare devices, and if this ever happens, the result is undefined.
