1 recomendación•1,183 vistas

This document describes a hardware detection tool called HDT that is implemented as part of the Syslinux project. HDT collects detailed hardware configuration information from systems in a user-friendly way. It works at a low level to gather information like CPU, memory, storage, and network details. The tool outputs this data in JSON format for easy sharing and automated reporting. A live demo of HDT is then shown to illustrate its features.

"In the beginning there was RPM, and it was good." Certainly, Linux packaging has solved many of the problems involved in shipping software, from creation to consumption and maintenance. As software development and deployment have evolved, however, new pain points have cropped up that have not been solved by traditional packaging tools. Are containers the answer? They may be able to solve many of the current problems, but they also introduce a new set of issues and ignore important lessons from the evolution of distribution-level packaging.

The OpenXT Project is an Open Source community producing a Xen-based platform for client devices with a focus on providing strong security properties. The different primary use cases of this project versus server-based Xen systems have motivated notable technical differences and consequently OpenXT should be of interest to anyone seeking to understand the full set of capabilities on offer within the Xen ecosystem. In this presentation, Christopher Clark will describe the technical architecture of OpenXT, its current status and development activity within the project and its engagement with the upstream OpenEmbedded and Xen projects. This will include an overview of OpenXT's differentiating features such as Measured Launch, Virtual TPMs, Linux-based stubdoms, a specialized input layer and a distinct PV USB stack for Windows and Linux.

Docker and other container runtimes are gathering momentum and becoming the new industry standard for server applications. Linux namespaces, commonly used to run Docker apps, come with a large surface of attack which is difficult to reduce. Intel’s Clear Containers use KVM to run containers as VMs to provide additional isolation. It is possible to provide VM-like isolation for containers without sacrificing performance. This talk focuses on the benefits of using Xen to provide an execution environment for Docker apps. The presentation starts by listing the requirements of this environment. It explains why monitoring container syscalls is important and what its security benefits are. The talk introduces a new paravirtualized protocol to virtualize IP sockets and provides the design and implementation details. The presentation clarifies the impact of the new protocol from a security perspective. The discussion concludes by comparing performance figures with the traditional PV network frontend and backend drivers in Linux, explaining the reasons for any performance gaps.

Released as Open Source Software (OSS) in June 2014, OpenXT is a collection of hardened Linux VMs configured to provide a user facing Xen platform for client devices. This default configuration was mostly static, applying some disaggregation techniques to segregate system components based on a general threat analysis. The goals embodied in this code base up to its release produced a one-size-fits-most configuration with extensibility in specific areas to encapsulate 3rd party value-add. With a community now forming around OpenXT we must come to terms with the limitations of the this approach. In this talk Philip will define what OpenXT is and in this definition, show that OpenXT can meet the varied needs of the security and virtualization community through the construction of a toolkit for the configurable disaggregation of a Xen platform.

We all want our devices to boot faster, but how much effort do you want to dedicate to optimizing and maintaining a custom kernel and apps? This presentation offers a graded list of things you can do to reduce boot time. They start with simple changes, such as adjusting the position of your main application the init sequence. Then there are the changes you can make to the kernel and bootloader configuration to speed things up, and finally, there are moderately advanced techniques such as using U-Boot in falcon mode. All of this is done using standard configuration techniques, with the idea of being able to maintain these changes in the future. I will show the effect of each of these changes on typical a embedded dev board so that you can judge for yourself where on the journey you want to jump off.

Hypervisors are becoming more and more widespread in embedded environments, from automotive to medical and avionics. Their use case is different from traditional server and desktop virtualization, and so are their requirements. This talk will explain why hypervisors are used in embedded, and the unique challenges posed by these environments to virtualization technologies. Xen, a popular open source hypervisor, was born to virtualize x86 Linux systems for the data center. It is now the leading open source hypervisor for ARM embedded platforms. The presentation will show how the ARM port of Xen differs from its x86 counterpart. It will go through the fundamental design decisions that made Xen a good choice for ARM embedded virtualization. The talk will explain the implementation of key features such as device assignment and interrupt virtualization.

We are all familiar with Android as an operating system for smarphones. Looking beyond that, Android is an open-source operating system that runs on top of Linux, which opens up a wide range of applications in the embedded space. Using Embedded Android, you get the well-known user interface, with it’s familiar touch screen gestures, and you get a well-known programming interface based on Java. So, why would you not want to consider Embedded Android?

Build your wireless router by OpenWrt. OpenWrt uses official GNU/Linux kernel sources and only adds patches for the system on chip and drivers for the network interfaces. The developer team tries to re-implement most of the proprietary code inside the GPL tarballs of the different vendors. There are free tools for writing new firmware images directly into the flash (mtd), for configuring the wireless lan chip (wlcompat/wificonf) and to program the VLAN-capable switch via the proc filesystem.

DevOps in the Real World is far from perfect, yet we all dream of that amazing auto-healing fully-automated CI/CD micro-service infrastructure that we'll have "someday." But until then, how can you really start using containers today, and what decisions do you need to make to get there? This session is designed for practitioners who are looking for ways to get started now with Docker and Swarm in production. This is not a Docker 101, but rather it's to help you be successful on your way to Dockerizing your production systems. Attendees will get tactics, example configs, real working infrastructure designs, and see the (sometimes messy) internals of Docker in production today.

Linux has emerged as a number one choice for developing OS based Embedded Systems. Open Source development model, Customizability, Portability, Tool chain availability are some reasons for this success. This course gives a practical perspective of customizing, building and bringing up Linux Kernel on an ARM based target hardware. It combines various previous modules you have learned, by combing Linux administration, Hardware knowledge, Linux as OS, C/Computer programming areas. After bringing up Linux, you can port any of the existing applications into the target hardware.

With the grown interest in virtualization from big players around the world there are more and more companies choose ARM SoCs as their target platform for running server environments. It is also known that majority of such SoCs come with broad coprocessors available on the die, e.g. GPU, DSP, security etc. But at the moment the only way to speed up guests with these is either using a para-virtualized approach or making that HW dedicated to a specific guest. Shared coprocessor framework for Xen aims to allow all guest OSes to benefit from this companion HW with ease while running unmodified software and/or firmware on guest side. You don’t need to worry about setting up IO ranges, interrupts, scheduling etc.: it is all covered, making support of new shared HW way faster. As an example of the shared coprocessor framework usage a virtualized GPU will be shown.

Wanting to avoid the Android experience, Google developers always aimed to make their Chrome OS Linux kernels as close to mainline as possible. However, when Chromebooks were first created, Google was left with no choice, the mainline kernel, in some subsystems, still did not have all the functionalities needed by Chromebooks. Hence, similarly to Android, Chrome OS had to develop their own out-of-tree code for the kernel and maintain that for a few different kernel versions. Luckily, over the last few years a strong and consistent effort has been happening to bring Chromebook devices closer to mainline. It has led to significant improvements that now make it possible to run mainline on Chrome OS devices. And not only Chromebooks, as these significant strides are also improving Arm-based SOCs and other key components of the rich Chromebook hardware ecosystem. In this talk, we will look at how and why upstream support for Chromebooks improved, the current status of various models, and what we expect in the future. Enric Balletbò i Serra

As the name would suggest, a Non-Maskable Interrupt (NMI) is an interrupt-like feature that is unaffected by the disabling of classic interrupts. In Linux, NMIs are involved in some features such as performance event monitoring, hard-lockup detector, on demand state dumping, etc… Their potential to fire when least expected can fill the most seasoned kernel hackers with dread. AArch64 (aka arm64 in the Linux tree) does not provide architected NMIs, a consequence being that features benefiting from NMIs see their use limited on AArch64. However, the Arm Generic Interrupt Controller (GIC) supports interrupt prioritization and masking, which, among other things, provides a way to control whether or not a set of interrupts can be signaled to a CPU. This talk will cover how, using the GIC interrupt priorities, we provide a way to configure some interrupts to behave in an NMI-like manner on AArch64. We’ll discuss the implementation, some of the complications that ensued and also some of the benefits obtained from it. Julien Thierry

At a rate of almost 9 changes per hour (24/7), the Linux kernel is definitely a scary beast. Bugs are introduced on a daily basis and, through the use of multiple code analyzers, *some* of them are detected and fixed before they hit mainline. Over the course of the last few years, Gustavo has been fixing such bugs and many different issues in every corner of the Linux kernel. Recently, he was in charge of leading the efforts to globally enable -Wimplicit-fallthrough; which appears by default in Linux v5.3. This presentation is a report on all the stuff Gustavo has found and fixed in the kernel with the support of the Core Infrastructure Initiative. Gustavo A.R. Silva

Modern SoC designs incorporate technologies from numerous vendors, each with their own inconsistent, confusing, undocumented and even contradictory terminology. The result is a mess of acronyms and product names which have a surprising impact on the ability to develop reusable, modular code thanks to the nature of the underlying IP being obscured. This presentation will dive into some of the misnomers plaguing the Arm ecosystem, with the aim of explaining why things are like they are, how they fit together under the architectural umbrella and how you, as a developer, can decipher the baffling ingredients list of your next SoC design!

GNU poke is a new interactive editor for binary data. Not limited to editing basic ntities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them. Once a user has defined a structure for binary data (usually matching some file format) she can search, inspect, create, shuffle and modify abstract entities such as ELF relocations, MP3 tags, DWARF expressions, partition table entries, and so on, with primitives resembling simple editing of bits and bytes. The program comes with a library of already written descriptions (or “pickles” in poke parlance) for many binary formats. GNU poke is useful in many domains. It is very well suited to aid in the development of programs that operate on binary files, such as assemblers and linkers. This was in fact the primary inspiration that brought me to write it: easily injecting flaws into ELF files in order to reproduce toolchain bugs. Also, due to its flexibility, poke is also very useful for reverse engineering, where the real structure of the data being edited is discovered by experiment, interactively. It is also good for the fast development of prototypes for programs like linkers, compressors or filters, and it provides a convenient foundation to write other utilities such as diff and patch tools for binary files. This talk (unlike Gaul) is divided into four parts. First I will introduce the program and show what it does: from simple bits/bytes editing to user-defined structures. Then I will show some of the internals, and how poke is implemented. The third block will cover the way of using Poke to describe user data, which is to say the art of writing “pickles”. The presentation ends with a status of the project, a call for hackers, and a hint at future works. Jose E. Marchesi

Operating system distributors often face challenges that are somewhat different from that of upstream kernel developers. For instance, some kernel updates often need to stay at least binary compatible with modules that might be “out of tree” for some time. In that context, being able to automatically detect and analyze changes to the binary interface exposed by the kernel to its module does have some noticeable value. The Libabigail framework is capable of analyzing ELF binaries along with their accompanying debug info in the DWARF format, detect and report changes in types, functions, variables and ELF symbols. It has historically supported that for user space shared libraries and application so we worked to make it understand the Linux kernel binaries. In this presentation, we are going to present the current support of ABI analysis for Linux Kernel binaries, the challenges we face, how we address them and the plans we have for the future.

Different upgrade and update strategies exist when it comes to embedded Linux system. If at development time none of these strategies have been chosen, adding them afterwards can be tedious task. Even harder it gets when the system is already deployed in the field and only accessible via a 3G connection. This talk is a developer experience of putting in place exactly that. Giving a return of experience on one way of doing it on a system running Barebox and a Yocto-based distribution. Patrick Boettcher

The I2C subsystem is not the shiniest part of the Linux Kernel. For embedded devices, though, it is one of the many puzzle pieces which just have to work. Wolfram Sang has the experience of maintaining this subsystem for nearly 7 years now. This talk gives a short overview of how maintaining works in general and specifically in this subsystem. But mainly, it will highlight noteworthy points in the timeline and lessons learnt from that. It will present trends, not so much regarding I2C but more the Linux Kernel and the embedded ecosystem in general. And of course, there will be plenty of anecdotes and bits from behind the scenes for your entertainment. Wolfram Sang

ITRenew is selling recertified OCP servers under the Sesame brand, those servers come either with their original UEFI BIOS or with LinuxBoot. The LinuxBoot project is pushing the Linux kernel inside bios flash and using userland programs as bootloader. To achieve quality on our software stack, as any project, we need to test it. Traditional BIOS are tested by hand, this is 2019 we need to do it automatically! We already presented the hardware setup behind the LinuxBoot CI, this talk will focus on the software. We use u-root for our userland bootloader; this software is written in Go so we naturally choose to use Go for our testing too. We will present how we are using and extending the Go native test framework `go test` for testing embedded systems (serial console) and improving the report format for integration to a CI.

About 60% of the Linux kernel source tree is devoted to drivers for a large variety of supported hardware components. Especially in the embedded world, the number of different SoC families, versions, and revisions, integrating a myriad of “IP cores”, keeps on growing. In this presentation, Geert will explain how to match drivers against hardware, and how to support a wide variety of (dis)similar devices, without turning platform and driver code into an entangled bowl of spaghetti.tra Starting with a brief history of driver matching in Linux, he will fast-forward to device-tree based matching. He will discuss ways to handle slight variations of the same hardware devices, and different SoC revisions, each with their own quirks and bugs. Finally, Geert will show best practices for evolving device drivers in a maintainable way, based on his experiences as an embedded Linux kernel developer and maintainer. Geert Uytterhoeven

Ftrace’s most powerful feature is the function tracer (and function graph tracer which is built from it). But to have this enabled on production systems, it had to have its overhead be negligible when disabled. As the function tracer uses gcc’s profiling mechanism, which adds a call to “mcount” (or more recently fentry, don’t worry if you don’t know what this is, it will all be explained) at the start of almost all functions, it had to do something about the overhead that causes. The solution was to turn those calls into “nops” (an instruction that the CPU simply ignores). But this was no easy feat. It took a lot to come up with a solution (and also turning a few network cards into bricks). This talk will explain the history of how ftrace came about implementing the function tracer, and brought with it the possibility of static branches and soon static calls! Steven Rostedt

Suricata is a network threat detection engine using network packets capture to reconstruct the traffic till the application layer and find threats on the network using rules that define behavior to detect. This task is really CPU intensive and discarding non interesting traffic is a solution to enable a scaling of Suricata to 40gbps and other. This talk will present the latest evolution of Suricata that knows uses eBPF and XDP to bypass traffic. Suricata 5.0 is supporting the hardware XDP to provide ypass with network card such as Netronome. It also takes advantage of pinned maps to get persistance of the bypassed flows. This talk will cover the different usage of XDP and eBPF in Suricata and shows how it impact performance and usability. If development time permit, the talk will also cover AF_XDP and the impact on this new capture method on Suricata. Eric Leblond

System memory configuration is a transparent operation nowadays, something that we all came to expect to just work out of the box. Still, it does happen behind the scenes every single time we boot our computers. This requires the cooperation of hardware components on the mainboard and on memory modules themselves, as well as firmware code to drive these. While it is possible to just let it happen, having a deeper understanding of how it works makes it possible to access valuable information from the operating system at run-time. I will take you through the history of system memory configuration from the mid 70s to now. We will explore the different types of memory modules, how their configuration data is stored and how the firmware can access them. We will see which problems had to be solved along the way and how they were solved. Lastly we will see how Linux supports reading the memory configuration information and what you can do with that information. Jean Delvare
