Linux Kernel 5.3 will boost IoT with Security Features

Linux Kernel 5.3 has been released with so much of updates in hardware line priority. From support for Raspberry pi firmware, driver to IPv4 address.


New Hardware Support:
  • Aspeed BMC support for a number of new server platforms: Facebook YAMP BMC Inspur fp5280g2 BMC machine, Microsoft Olympus BMC, Swift BMC machine, YADRO VESNIN BMC, and Lenovo Hr630 BMC 
  • Kontron SMARC SoM (several i.MX6 versions) 
  • Novtech's Meerkat96 (i.MX7) 
  • STMicro Avenger96 board 
  • Purism Librem 5 devkit (i.MX8MQ)
  • Google Cheza (Qualcomm SDM845)
  • Qualcomm Dragonboard 845c (Qualcomm SDM845) 
  • Hugsun X99 TV Box (Rockchip RK3399)
  • Khadas Edge/Edge-V/Captain (Rockchip RK3399)
  • Add core dtsi file for RK3399Pro SoCs 
  • renesas: Add HiHope RZ/G2M board support 
  • Add support for phyBOARD-REGOR-AM335x 
  • Introduce the NXP LS1021A-TSN board 
  • meson8b: mxq: improve support for the TRONFY MXQ S805 
  • Workaround errata A12 857271 / A17 857272 
  • Workaround for I-Cache line size mismatch between CPU cores
  • KVM: Support chained PMU counters
New pidfd functionality let the devices service manager to work on PID reuse problems.

The Major turn towards IoT is the safety of its usage.

The critic of IoT is about the security updates must be on the kernel level as software under threats and also the speed of response.

ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind, optimized to streamline embedded development through an open-source platform. It is built for embedded IoT with a small footprint and real-time features.

Project ACRN - running IoT software on Virtual Machine to ensure security much like a docker feature separating its functionality to extend its security levels.
