LinuxCon+CloudOpen North America 2014

UEFI is becoming increasingly common in the latest computer systems, with adoption broadening to include a wider variety of Linux-based and open source operating systems. Learn about UEFI technology and the organization driving the evolution of platform firmware technology – The UEFI Forum. This session will also provide an overview of how UEFI technology benefits the Linux community by providing a safe path for firmware implementations.

The UEFI Secure Boot Feature can be used to protect Linux-based systems but only if the Linux installation is properly configured to create a trusted boot environment.  This session will provide a user-level understanding of how to setup and install a system with Secure Boot as well as introducing some of the methods, such as MOK, which are available to provide continued protection throughout the stages of Linux boot.

Stable Linux deployments depend on quality firmware. This includes UEFI runtime services, ACPI and security vulnerabilities. This presentation gives an overview of UEFI test tools available in open source (FWTS, CHIPSEC and the Linux UEFI Validation OS) and discusses how they are relevant to Linux development.

ARM server is an exciting platform driving new ideas about how to build servers. UEFI and ACPI are the core technologies that standardize the platform and enable many hardware, software and OS vendors to build products that work together.

In this presentation, we discuss the new ARM related content in the ACPI v5.1 specification published by the UEFI Forum, and how UEFI/ACPI advancements implement the ARM Server Baseline Boot Requirements. We also cover the ongoing work at Linaro to implement these changes.

UEFI SecureBoot is a feature even hobbyist kernel developers can take advantage of to secure their systems. This presentation will go through the process of properly signing a custom build Linux kernel with a user generated private key and also how to insert the matching public key into the proper BIOS key database. Properly using UEFI SecureBoot ensures that there is no rootkit or man-in-the-middle attack between the BIOS and the Linux boot loader.
