Subject: [PATCH v3 00/10] HID: validate report details

Hi guys,

here is the v3 of the CVE fixes.

I have tested the multitouch and logitech-dj part, and the lenovo-tpkbd has been
tested in the bug referenced in patch 10.

Cheers,
Benjamin

Changes since v2:
- fix lenovo-tpkbd report validation
- fix lenovo-tpkbd not releasing the device when the report was not valid
- use generic tests found in previous hid-multitouch patches, so that this will
  not happen again
- fix input_report index retrieving in hid-multitouch

Original message from Kees (v2):

These patches introduce a validation function for HID devices that do
direct report value accesses, solving a number of heap smashing flaws.

This version changes to using an field-index-based checker for the new
"hid_validate_values()" which requires callers to loop across fields if
they use more than one field.

Benjamin Tissoires (3):
  HID: validate feature and input report details
  HID: multitouch: validate indexes details
  HID: lenovo-tpkbd: fix leak if tpkbd_probe_tp fails

Kees Cook (7):
  HID: provide a helper for validating hid reports
  HID: zeroplus: validate output report details
  HID: sony: validate HID output report details
  HID: steelseries: validate output report details
  HID: LG: validate HID output report details
  HID: lenovo-tpkbd: validate output report details
  HID: logitech-dj: validate output report details
