Introduction
This plugin is used to talk to the Intel ME device, typically CSME.
It allows us to get the Platform Key as used for BootGuard and to get the version number for the Intel AMT.
If AMT is enabled and provisioned and the AMT version is between 6.0 and 11.2, and you have not upgraded your firmware, you are vulnerable to CVE-2017-5689 and you should disable AMT in your system firmware.
This code is inspired by 'AMT status checker for Linux' by Matthew Garrett which can be found here: https://github.com/mjg59/mei-amt-check
That tool in turn is heavily based on mei-amt-version from samples/mei in the Linux source tree and copyright Intel Corporation.
GUID Generation
These devices use the existing GUIDs provided by the ME host interfaces.
Vendor ID Security
The devices are not upgradable and thus require no vendor ID set.
External Interface Access
This plugin requires ioctl(IOCTL_MEI_CONNECT_CLIENT) to /dev/mei0.
