During the lectures... I Don’t hesitate to ask questions. Other people in the audience may have similar questions too. I This helps the trainer to detect any explanation that wasn’t clear or detailed enough. I Don’t hesitate to share your experience, for example to compare Linux with other operating systems used in your company.

I We cannot support more than 8 workstations at once (each with its board and equipment). Having more would make the whole class progress slower, compromising the coverage of the whole training agenda (exception for public sessions: up to 10 people). I So, if you are more than 8 participants, please form up to 8 working groups. I Open the electronic copy of your lecture materials, and use it throughout the practical labs to find the slides you need again. I Don’t hesitate to copy and paste commands from the PDF slides and labs. - Kernel, drivers and embedded Linux - Development, consulting, training and support - https://bootlin.com 13/296 Advise: write down your commands! During practical labs, write down all your commands in a text file. I You can save a lot of time re-using commands Lab commands in later labs. Cross-compiling kernel: export ARCH=arm I This helps to replay your work if you make export CROSS_COMPILE=arm-linux- make sama5_defconfig significant mistakes. Booting kernel through tftp: I You build a reference to remember commands setenv bootargs console=ttyS0 root=/dev/nfs setenv bootcmd tftp 0x21000000 zImage; tftp 0x22000000 dtb; bootz 0x21000000 - 0x2200... in the long run. I That’s particular useful to keep kernel Making ubifs images: mkfs.ubifs -d rootfs -o root.ubifs -e 124KiB command line settings that you used earlier. -m 2048 -c 1024 I Also useful to get help from the instructor, Encountered issues: Restart NFS server after editing /etc/exports! showing the commands that you run. gedit ~/lab-history.txt - Kernel, drivers and embedded Linux - Development, consulting, training and support - https://bootlin.com 14/296 Cooperate! As in the Free Software and Open Source community, cooperation during practical labs is valuable in this training session: I Use the dedicated Matrix channel for this session I If you complete your labs before other people, don’t hesitate to help them and investigate the issues they face. The faster we progress as a group, the more time we have to explore extra topics. I Explain what you understood to other participants when needed. It also helps to consolidate your knowledge. I Don’t hesitate to report potential bugs to your instructor. I Don’t hesitate to look for solutions on the Internet as well. - Kernel, drivers and embedded Linux - Development, consulting, training and support - https://bootlin.com 15/296 Practical lab - Training Setup Prepare your lab environment I Download and extract the lab archive - Kernel, drivers and embedded Linux - Development, consulting, training and support - https://bootlin.com 16/296 Introduction to Embedded Linux Introduction to Embedded Linux embedded Linux and kernel engineering © Copyright 2004-2021, Bootlin.

Moreover, standard for deploying applications in data centers. containers significantly reduce operational costs through However, deployed containers frequently include a higher consolidation density and power minimization, wide-range of tools (e.g., debuggers) that are not required especially in multi-tenant environments. Because of all for applications in the common use-case, but they these advantages, it is no surprise that containers have seen are included for rare occasions such as in-production wide-spread adoption by industry, in many cases replacing debugging. As a consequence, containers are significantly altogether traditional virtualization solutions [17]. larger than necessary for the common case, thus increasing the build and deployment time. Despite being lightweight, deployed containers often include a wide-range of tools such as shells, editors, CNTR1 provides the performance benefits of lightweight coreutils, and package managers. These additional tools containers and the functionality of large containers by are usually not required for the application’s core function splitting the traditional container image into two parts: the — the common operational use-case — but they are “fat” image — containing the tools, and the “slim” image included for management, manual inspection, profiling, — containing the main application. At run-time, CNTR and debugging purposes [64]. In practice, this significantly allows the user to efficiently deploy the “slim” image and increases container size and, in turn, translates into then expand it with additional tools, when and if necessary, slower container deployment and inefficient datacenter by dynamically attaching the “fat” image.

  • Hands-On Kernel Lab
    Hands-on Kernel Lab Based on the Yocto Project 1.4 release (dylan) April 2013 Tom Zanussi <[email protected]> Darren Hart <[email protected]> Introduction Welcome to the Yocto Project Hands-on Kernel Lab! During this session you will learn how to work effectively with the Linux kernel within the Yocto Project. The 'Hands-on Kernel Lab' is actually a series of labs that will cover the following topics: • Creating and using a traditional kernel recipe (lab1) • Using 'bitbake -c menuconfig' to modify the kernel configuration and replace the defconfig with the new configuration (lab1) • Adding a kernel module to the kernel source and configuring it as a built-in module by adding options to the kernel defconfig (lab1) • Creating and using a linux-yocto-based kernel (lab2) • Adding a kernel module to the kernel source and configuring it as a built-in module using linux-yocto 'config fragments' (lab2) • Using the linux-yocto kernel as an LTSI kernel (configuring in an item added by the LTSI kernel which is merged into linux-yocto) (lab2) • Using an arbitrary git-based kernel via the linux-yocto-custom kernel recipe (lab3) • Adding a kernel module to the kernel source of an arbitrary git-based kernel and configuring it as a loadable module using 'config fragments' (lab3) • Actually getting the module into the image and autoloading it on boot (lab3) • Using a local clone of an arbitrary git-based kernel via the linux-yocto- custom kernel recipe to demonstrate a typical development workflow (lab4) • Modifying the locally cloned custom

There are many parameters to take into account: l Is this a new project or the evolution of an existing product? l Using the same SW stack? Re-using existing code? l Is your team familiar with a particular OS? Ø Using an OS you are already comfortable with can help l What are the HW constraints of your system?

    Securing Embedded Systems: Analyses of Modern Automotive Systems and Enabling Near-Real Time Dynamic Analysis Karl Koscher A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2014 Reading Committee: Tadayoshi Kohno, Chair Gaetano Borriello Shwetak Patel Program Authorized to Offer Degree: Computer Science and Engineering © Copyright 2014 Karl Koscher University of Washington Abstract Securing Embedded Systems: From Analyses of Modern Automotive Systems to Enabling Dynamic Analysis Karl Koscher Chair of the Supervisory Committee: Associate Professor Tadayoshi Kohno Department of Computer Science and Engineering Today, our life is pervaded by computer systems embedded inside everyday products. These embedded systems are found in everything from cars to microwave ovens. These systems are becoming increasingly sophisticated and interconnected, both to each other and to the Internet. Unfortunately, it appears that the security implications of this complexity and connectivity have mostly been overlooked, even though ignoring security could have disastrous consequences; since embedded systems control much of our environment, compromised systems could be used to inflict physical harm. This work presents an analysis of security issues in embedded systems, including a comprehensive security analysis of modern automotive systems. We hypothesize that dynamic analysis tools would quickly discover many of the vulnerabilities we found. However, as we will discuss, there
