Kernel developers working on confidential computing for virtualized environments in x86 operate under a set of assumptions regarding the Linux kernel threat model that differs from the traditional view. Historically, the Linux threat model acknowledges attackers residing in userspace, as well as a limited set of external attackers that are able to interact with the kernel through networking or limited HW-specific exposed interfaces (e.g. USB, thunderbolt). The goal of this document is to explain additional attack vectors that arise in the virtualized confidential computing space.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
