Kernel Log - Coming in 3.7 (Part 3): Infrastructure

Filed under
Linux

Linux 3.7 can sign kernel modules and verify those signatures and, therefore, the integrity of the modules before loading them (1, 2, 3, 4, 5, 6, 7). Some enterprise distributions have had similar features for a while – for example, to ensure that the modules used for troubleshooting are really from the distribution kernel. Developers have been working on integrating the functionality into Linux as some distributions want to load only signed kernel modules when booted with UEFI secure boot – this is now possible with the integrated code.

Another new feature is the integrity appraisal extension for the Integrity Measurement Architecture (IMA), which the kernel has supported for quite some time now (1, 2). IMA can store signed hashes for files and use them to recognise when binaries from the Linux installation have been changed.

Linux 4.2 Bringing Support For ARCv2, HS38 CPU Cores

The ARC architecture updates for the Linux 4.2 kernel have landed. With the ARC architecture updates in Linux 4.2 comes support for HS38 cores, which in turn are based on the Synopsys next-gen ISA known as ARCv2. The ARCv2 ISA is faster and more feature-rich than their original instruction set architecture. The HS38 cores have a 10-stage pipeline core with MMU support, SMP up to four cores, and other new features. The HS38 processor is still 32-bit and is "optimized for high-performance embedded applications running Linux." Read more Also: Radeon & AMDGPU DRM Fixes Queue Up For Linux 4.2
