platform/olpc: Fix uninitialized data in debugfs write

2022-08-21T13:16:02Z

[ Upstream commit 40ec787e1adf302c11668d4cc69838f4d584187d ] The call to: size = simple_write_to_buffer(cmdbuf, sizeof(cmdbuf), ppos, buf, size); will succeed if at least one byte is written to the "cmdbuf" buffer. The "*ppos" value controls which byte is written. Another problem is that this code does not check for errors so it's possible for the entire buffer to be uninitialized. Inintialize the struct to zero to prevent reading uninitialized stack data. Debugfs is normally only writable by root so the impact of this bug is very minimal.

Pull x86 platform driver updates from Andy Shevchenko: "Gathered a bunch of x86 platform driver changes. It's rather big, since includes two big refactors and completely new driver: - ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. - Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. - From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. - Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. - The OLPC XO-1.75 platform is now supported. - CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. - Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal. Also miscellaneous fixes here and there, mostly for Acer WMI and various Intel drivers" * tag 'platform-drivers-x86-v5.3-1' of git://git.infradead.org/linux-platform-drivers-x86: (74 commits) platform/x86: Fix PCENGINES_APU2 Kconfig warning tools/power/x86/intel-speed-select: Add .gitignore file platform/x86: mlx-platform: Fix error handling in mlxplat_init() platform/x86: intel_pmc_core: Attach using APCI HID "INT33A1" platform/x86: intel_pmc_core: transform Pkg C-state residency from TSC ticks into microseconds platform/x86: asus-wmi: Use dev_get_drvdata() Documentation/ABI: Add new attribute for mlxreg-io sysfs interfaces platform/x86: mlx-platform: Add more reset cause attributes platform/x86: mlx-platform: Modify DMI matching order platform/x86: mlx-platform: Add regmap structure for the next generation systems platform/x86: mlx-platform: Change API for i2c-mlxcpld driver activation platform/x86: mlx-platform: Move regmap initialization before all drivers activation MAINTAINERS: Update for Intel Speed Select Technology tools/power/x86: A tool to validate Intel Speed Select commands platform/x86: ISST: Restore state on resume platform/x86: ISST: Add Intel Speed Select PUNIT MSR interface platform/x86: ISST: Add Intel Speed Select mailbox interface via MSRs platform/x86: ISST: Add Intel Speed Select mailbox interface via PCI platform/x86: ISST: Add Intel Speed Select mmio interface platform/x86: ISST: Add IOCTL to Translate Linux logical CPU to PUNIT CPU number ...
