This fixes CVE-2017-1000407. KVM allows guests to directly access I/O port 0x80 on Intel hosts. If the guest floods this port with writes it generates exceptions and instability in the host kernel, leading to a crash. With this change guest writes to port 0x80 on Intel will behave the same as they currently behave on AMD systems. Prevent the flooding by removing the code that sets port 0x80 as a passthrough port. This is essentially the same as upstream patch |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
