Tutorial: An Introduction to Linux Control Groups (cgroups) - Michael Kerrisk, man7.org Training and Consulting
Control groups (cgroups) are a method of grouping processes for the purpose of monitoring, management, and control. Using cgroups, we can: limit CPU and memory consumption; freeze and resume execution of a group; limit device access; limit the number of processes in a group; and more. Cgroups are a key building block in container systems and are also used in systemd. This tutorial provides an introduction to cgroups, covering both v1 and v2. The focus is on understanding the operation of the cgroup system itself, rather than going into details of individual controllers. So we'll look at how to create and populate cgroups using shell commands that operate on the cgroup filesystem and look at topics such as notification, inheritance, and delegation. Bring a laptop so you can walk through some of the examples.

Workshop: Building and Operating an OSS Data Science Platform - Jörg Schad, Mesosphere
There are many great tutorials for training your deep learning models using TensorFlow, Keras, Spark or one of the many other frameworks. But training is only a small part of the overall deep learning pipeline.

Ever wonder about how to set up a complete end-to-end data science pipeline starting with data storage and preparation, interactive notebooks, distributed training, CI/CD automation, and serving and monitoring the trained models.

In this workshop, we will build an end-to-end OSS data science platform including:
* Data preparation using Apache Spark
* JupyterLab self-service for data scientists
* Data storage using HDFS
* Distributed training
* Automation & CI/CD using Jenkins
* Resource sharing (including GPUs) between multiple user/jobs
* Model and metadata storage
* Model serving and monitoring

Lab: Observe Your Applications with OpenTracing - Kevin Crawley, Instana
# Observability Workshop: Kubernetes, Tracing, and Metrics

The goal of this workshop is to familiarize application and site reliability engineers with the benefits that modern observability tools provide to the builders and curators of cloud native applications. 

In this workshop attendees will configure a RBAC-enabled vanilla K8S cluster in GKE, deploy prometheus and jaeger in support of observing and monitoring a distributed microservice application, instrument that application by introducing libraries and tooling to support capturing business metrics as well. Each attendee will configure, update, and deploy a cloud native application utilizing the following technologies:

* Google Kubernetes Engine - we will bootstrap a small K8S cluster using Googles free $300 trial.
* Gitlab - we will implement a CI/CD pipeline with our cloud native application in order to build and deploy our application while we integrate Prometheus, Opentracing and Jaeger into our application.
* Helm - we will utilize Helm to deploy policies, monitoring services, ingress rules, operators, and our demo application.
* Spring Petclinic Microservices - we will utilize a distributed Java/Springboot/Angular based cloud native application. We will start with an unmonitored version and work together to bring observability to our application.
* Grafana / Prometheus - we will demonstrate how to utilize prometheus operators to configure prometheus scrape targets. We will utilize micrometer to expose JMX metrics, install custom dashboards, and setup custom business metric dashboards and alerting rules.
* Jaeger / Opentracing - we will demonstrate how to utilize the Jaeger client and opentracing libraries to gain visibility into the communication happening between your microservices and database systems.

During this workshop we will discuss and explore some of the following topics:

* How Distributed Tracing works and why it's become a requirement when deploying cloud native applications.
* The pitfalls, challenges, and solutions to managing and deploying observability at scale.
* What's missing? Important aspects of our operations are't being monitored, let's find out what and, more importantly, how to fix it.
* The history of Spring Petclinic and the decision behind refactoring to no longer depend on Eureka/Zuul (Spring Cloud).
* Challenges of utilizing Opentracing implementation in non-java languages/frameworks along with some code samples.
* We'll uncover why service meshes, such as Istio, will reduce the technical costs of observability.
* Troubleshooting and Root Cause Analysis 101. We'll do our best to _not_ DDOS the conference wifi and put some stress on our newly deployed applications by simulating load from a GCE instance.
* Where is the innovation happening in observability? Let's discuss automation, AI, and the future.

Technical Requirements

* Modern unix-like OS and a browser (windows should work, if you have git bash)
* git, code editor, openssh, vim, bash
  * basic understanding and recent experience using these tools will be beneficial when participating with the group during the lab sessions
* google cloud account with or without billing enabled*
* gitlab account**

> \* : Google offers a $300 voucher to use for their trial. However, Google Cloud requires a credit card when signing up to verify you're not a bitcoin miner. Even if you have an account I recommend creating a new gmail account (if necessary) and using that.
> \** : Gitlab is free. You'll be forking a repository and pushing code/configuration changes to that fork.

Developer Requirements

* Some programming experience [java, c, php, python, etc]
* Development tooling experience [make, mvn, yaml, vim]
* Unix-like tooling [bash, scripting, vim]
* Basic networking (DNS/routing)
  * We will use `nip.io` to give our application a public wildcard domain. If you manage your own domains you could alternatively use your own domain name (we will only cover using `nip.io` in the workshop)

Q+A:

> Q: Will we walk through signing up for Google Cloud and Gitlab at the beginning of the workshop?
> A: Yes. However, I highly recommend you do this prior to the workshop. Google `new gitlab account` and `google cloud trial` for answers.

> Q: Why Gitlab / Google?
> A: Gitlab has a built-in CI/CD pipeline system and integration with K8S tooling. Google has an extremely mature and feature-rich managed solution for k8s. Also, it's free.

> Q: I already have a "company", "personal", "sandbox" Google Cloud account, can I just use that?
> A: This would not be recommended. Your account could have policies or restrictions which would prevent you from following along with the exercise.

> Q: I got this, I know more about Google Cloud than Google does. How much will this cost me?
> A: Free if you just sign up for a new account. Otherwise, it's about $10-15 for the compute/network/etc time over the course of the workshop.

> Q: Why can't we just use minikube? 
> A: This workshop was built using a 2018 XPS 13 w/ a quad core and 16gb ram using minikube. The project quickly outgrew this machine and operationally requires at minumum of 8 real cores and 20gb of ram (at load).

> Q: Wow, your laptop sucks. I have a 12-core alienware with 64gb of ram. Can I just use minikube?
> The project itself includes dependencies on large frameworks and libraries, requires heavy weight compilers, and multiple build tools. By operationalizing this project, we offload all of the network and compute requirements to the cloud - we only need our local machines to make code changes and commit them.
> To answer your question, yes, you can. But please, don't.

Tutorial: What's New in Control Groups (cgroups) Version 2? - Michael Kerrisk, man7.org Training and Consulting
Soon after the release of cgroups v1 in 2008, people realized there were many problems that resulted from its uncoordinated design and implementation. Several years of work to fix those problems resulted in the redesigned cgroups v2 in 2016. Even then, work remained to be done, with the absence of some key features blocking the adoption of cgroups v2. One of the main logjams was finally broken at the start of 2018 with the merging of the v2 CPU controller. It seems likely that cgroups v2 will become more widely used in the not too distant future.

In this talk, we'll briefly consider some of the problems in cgroups v1 that motivated the cgroups v2 redesign, and then go on to look at the differences and new features in cgroups v2. We'll also look at what pieces are still missing in cgroups v2 and some other possible changes that may come in the future. Some familiarity with the cgroups mechanism will be assumed.

Building Inclusive Open Source Communities - Laura Gaetano, Travis Foundation
Tech has a diversity problem: marginalised people are being pushed out of the industry; their voices and experiences are erased. Open Source is particularly bad, with too few contributors who aren’t white, male, cisgender and able-bodied.

What if things were different? What if we could create spaces that are welcoming, where we show empathy and compassion? What if those qualities could reflect in our work, ultimately helping us create better software?

In this talk, you will hear stories of first-time contributions, successful examples in supporting and mentoring newcomers, and find out steps you can take as an Open Source contributor or maintainer to make your community more inclusive.

Buildroot vs Yocto: Differences for Your Daily Job - Luca Ceresoli, AIM Sportline
Buildroot and Yocto, the two leading embedded Linux buildsystems, have largely overlapping goals but vastly different implementations.

Perhaps you're familiar with either, and wonder how your daily job would change if you used the other.

Luca will share insights he gained while managing projects with both tools, spending a lot of time in learning how to achieve the same goals in a different way.

He will give a sort of "translation table" to ease the transition between the two, covering: bootstrapping a project, what happens under the hood, invoking the build, customizing the rootfs and tweaking recipes.

The Wi-Fi Alliance® Multi-AP specification allows access points to work together to create a self-monitoring and self-adapting network providing optimal coverage in the home. The prpl foundation has sponsored an open-source, "carrier-grade" implementation of this specification called prplMesh, which is based on an implementation of the IEEE 1905.1a specification provided by the BroadBand Forum. This talk explains the architecture of prplMesh, how it fits into the existing network stack (bridge configuration, hostapd/wpa_supplicant, cfg80211), and what it means to be "carrier-grade". We will also show how it integrates with openWRT and RDK-B. Finally, we will highlight how several companies have banded together to fund this development.

Supporting Hardware Codecs in a Linux System - Maxime Ripard, Bootlin
Every modern multimedia-oriented ARM SoC usually has a hardware controller to decode and encode video streams. The Linux kernel framework of choice to support these controllers is the v4l2 subsystem.

This talk will walk through the changes that were needed to support our codec in the v4l2 stack, the challenges we faced during the driver development and, once the driver development done, the issues we faced
to make the hardware decoding useful to general-purpose video players like Kodi, gstreamer or VLC.

Internals of Docking Storage with Kubernetes Workloads - Dennis Chen, Arm
Storage is one of the three key elements in cloud computing, and Kubernetes is a popular container orchestration system. With more and more persistent storage volume being used in this field, it becomes increasingly challenging to deploy standalone clusters, a natural solution is to deploy a storage cluster automatically with Kubernetes primitives and make use of it like volume provisioning and attachment for the workload cluster.

Currently Kubernetes provides two frameworks to dock an external storage cluster: FlexVolume and CSI(Container Storage Interface).Consequently, there will be two parts in this session, in the first part, Dennis will dissect the internals of the two solutions: how they work, and the advantages and limitations for each one. In the second part Dennis will take the Rook project hosted by CNCF and a Ceph cluster as a specific example to discuss a practical implementation in the real world.

A Day in the Life of a Log Message: Navigating a Modern Distributed System - Kyle Liberti & Josef Karasek, Red Hat
From its birth in a microservice to its end in storage, a log message in a modern distributed system travels through a labyrinth of computing abstractions. Although these abstractions empower developers to construct large performant systems, they typically become very complicated when integrated together. In this presentation, Josef Karásek and Kyle Liberti will map the journey of a log message as it traverses a distributed data streaming pipeline built from Apache Kafka and OpenShift Origin. Then, they will demonstrate this system’s elegance as they flood it with traffic.

PostgreSQL + Linux Kernel = Friendship - Dmitry Dolgov, Zalando SE
PostgreSQL is a database that heavily relies on functionality provided by an OS. This approach allows the reuse of some best practices and algorithms of utilizing machine resources like memory or CPU time. But on the other hand, it means PostgreSQL dependency on an OS - if you configure your OS it may significantly affect database performance.

In this talk, we’ll talk about common techniques of configuring the Linux kernel to work efficiently with PostgreSQL. We’re going to discuss PostgreSQL and kernel internals, some important questions about how they work, and how different options or features of the Linux kernel can help you to manage the highload with PostgreSQL.

Sustaining OSS: Going from Consuming to Contributing and Leading - Nithya Ruff, Comcast
According to BlackDuck's 2015 survey, 97% of enterprises use OS in some form or the other. Often companies stop at Consumption of OSS. When someone keeps attending lunch or dinner potlucks and never brings a dish to share, they soon lose their welcome. Yet, it is often a difficult thing to do for many companies. Either because of business justifications needed or difficult processes, many companies do not contribute and seriously hurt their own effectiveness and the sustainability of open source I will cover some strategies I have tested and succeeded with in the companies I have worked at. Learning to move past consumption through streamlining the contribution process and understanding the business case for contributions is essential for companies in OSS.

Can We Build a Safety Integrity Level System with Linux - Tiejun Chen, VMware
Linux is playing very well in the case of embedded system. But actually a variety of embedded systems make IoT so Linux definitely still can contribute here. But many IoT device are deployed in the critical infrastructures like the energy generation, avionic, automotive, etc, where everything need to be certified according to different specifications. So we need to explore making Linux itself certified.

Some efforts like SIL2LinuxMP is working on this but we’d like to further explore more on this area. With this effort, in our presentation we'd like to review together if-how we build a customized Linux distribution with some technologies:

  • Every system service are containerized.
  • To be deterministic
  • Unikernel context
  • Minimize kernel
  • Some potential hardware features
  • To be stable

The Modern Linux Graphics Stack on Embedded Systems - Michael Tretter, Pengutronix
Wayland advances to replace X as the goto windowing system in Linux, many applications and graphic toolkits are rapidly improving their Wayland support. Recent additions to the Direct Rendering Manager (DRM), e.g., atomic modeset and format modifiers, allow compositors to make smarter decisions how to utilize the hardware. This is critical for embedded systems, as these decisions affect the graphics performance and power usage. Therefore, a Wayland compositor becomes a compelling choice for building embedded systems that feature any graphical user interface.

Michael will walk through the Linux graphics stack from Kernel drivers to applications to show the components of the modern Linux graphics stack. In addition to DRM and Wayland, Michael will focus on Weston, the reference Wayland compositor.

Debugging Network Applications Using Container Technology - Pavel Šimerda, prgcont.cz
Container projects like LXC and Docker use Linux kernel namespacing features for container based deployment of applications. We will use kernel features together with Python and convenience libraries to instead perform debugging, experiments and test automation.

While a combination of bash, strace, ltrace or ptrace called directly from C program code do their job well, we can do the same in Python while gathering all information at once and driving the whole process as a single entity.

All of this can be driven interactively or fully automated. Pavel has already used automation to drive tests using client and server programs, collecting and processing data from the individual tests in a uniform way. Use your imagination and you can take it to another level.

Getting Your Patches in Mainline Linux: What Not To Do (and a Few Things You Could Try Instead) - Marc Zyngier, ARM
You've worked hard to develop a new feature, fix a tricky problem, or clean up an unloved part of the kernel. You have posted the patches on the relevant mailing lists and yet can't manage to get them merged. You can't get them past the maintainers, and maybe not even manage to attract their interest. What is happening?

Getting patches into the mainline Linux tree can be a tricky thing, especially for newcomers. The kernel does carry a long description of the process of writing and submitting the patches, but doesn't actually describe the complex set of interactions that take place between the submitter and the maintainer, and how trust gets build between the two.

This talks proposes to detail these interactions, and to offer the point of view of a contributor that grew into a maintainer, giving a number of examples of what not to do, and what you could try doing
instead.

Using Seccomp to Limit the Kernel Attack Surface - Michael Kerrisk, man7.org Training and Consulting
The seccomp (secure computing) facility is a means to select exactly which system calls a program is permitted to make and to restrict the arguments that may be passed to those system calls. System call filtering is achieved by writing BPF programs--programs written for a small in-kernel virtual machine that is able to examine system call numbers and arguments. Seccomp applications include sandboxing and failure-mode testing, and seccomp is by now used in a number of web browsers, container systems, and elsewhere. After outlining the basics of the BPF virtual machine, we look at some examples of filtering programs that restrict the set of permitted system calls, consider some productivity aids for seccomp writing filters, and note also some caveats to with respect to the use of seccomp.

The OPNFV community has developed a comprehensive set of open source test tools and test methodologies for NFVIs and VM-based cloud platforms. As the number of open source projects and use cases grows, so does the need for robust resiliency and interop testing. We need to look at how to evolve our tools to meet the requirements of emerging and future use cases (e.g. edge computing, cloud native). This talk will take a look at the OPNFV tools and show how they can be used by other open source projects (by showing how they are used in OPNFV). We will discuss how to run our tools against many different deployments, test different components of your system (VIM, vswitch, storage, etc.) and perform different types of testing (infrastructure verification, feature validation, stress and resiliency testing, performance benchmarking, characterization, etc.).
We will aim to start a discussion on requirements and solutions.

Who's Running my Pods!? A Deep Dive into Kubernetes and the Container Runtime Interface - Phil Estes, IBM
Kubernetes is far and away the most popular project around container orchestration today. One little known fact to some is that Kubernetes itself has no code to run or manage Linux or Windows containers.

So, what code *is* running the containers within your Kubernetes pods? Since Kubernetes 1.5 a new API contract, the Container Runtime Interface (CRI), allows any container runtime to plug into the kubelet configuration and provide container runtime services for Kubernetes.

In this talk we'll look at the CRI options that exist today, and then deep dive into how the CNCF containerd project and it's CRI-implementing plugin work in concert with Kubernetes to run your pods. This will lead into a deep-dive at the command line, showing via live demos how Kubernetes, the CRI, and CRI-supporting runtimes like containerd work together to handle the container lifecycle operations.

Deferred Problem: Issues With Complex Dependencies Between Devices in Linux Kernel - Andrzej Hajda, Samsung
Many devices have complex dependencies, especially on embedded platforms. They use resources provided by different devices: regulators, gpios, local buses, etc. Resource providers also use resources. Some are required, some are optional. Circular dependencies are not uncommon.
The popular picture of devices as a neat tree should be replaced by an obscure jungle.
Lack of proper handling of device dependencies in Linux Kernel hurts the system in multiple ways: slower bring-up of important subsystems, no support for optional resources, ugly hacks, uncoordinated development of workarounds in multiple subsystems, buggy device unbinding.

Andrzej will describe current state of device dependencies in Kernel: where are the problems, how to solve it with existing frameworks, what is still missing. He will also describe his proposition to solve missing parts: Resource Tracking Framework.

Developing Open-Source Software RTOS with Functional Safety in Mind - Anas Nashif, Intel
Open-source software development and how open-source projects are run is often seen as incompatible with functional safety requirements and established processes and standards. Open-source has however been used and is used on a regular basis in applications with safety requirements however in most cases the open-source software is forked and developed behind closed doors to comply with safety standards and processes and using existing infrastructure and tools not common or not available in public and in open-source.

This talk will show how the Zephyr project is moving to a new development process and methodology that uses existing and public tools to address many of the requirements and foundations that would help with using Zephyr in applications depending on functional safety.

Introduction to Linux Kernel Driver Programming - Michael Opdenacker, Bootlin (Additional Track Registration Required)
Important Note: This session is only open to the 50 people who have registered for the E-ALE track, at an additional $100.00 fee.

This tutorial will explain the Device Model, the mechanism that the Linux kernel offers to bind drivers to devices and to expose each device to userspace. Even though the way to detect or describe devices can depend on the bus or CPU architecture, the infrastructure binding devices with drivers are universal and therefore applies to all types of device drivers in the Linux kernel. Similarly, exposing devices to user space always follows the same philosophy.

This tutorial won't have practical labs but will be illustrated by studying several types of drivers, showing various ways of managing multiple devices in the same driver, and implementing the references between devices managed by a bus and devices that userspace sees.

Streaming Pipelines for Neural Machine Translation - Suneel Marthi, ASF
Machine Translation is important when having to cater to different geographies and locales for news or eCommerce website content. Machine Translation systems often need to handle a large volume of concurrent translation requests from multiple sources in multiple languages. They have to do this in real time while making efficient use of specialized hardware.

Many Machine Translation preprocessing tasks like Text Normalization, Language Detection, Sentence Segmentation etc. can be performed at scale in a real time streaming pipeline utilizing Apache Flink. We will be looking at a few such streaming pipelines leveraging Apache OpenNLP components. These components will preprocess data into a format that can be consumed by a Neural Machine Translation library.

We'll demonstrate and examine the end-to-end throughput and latency of a pipeline that detects language and translates news articles shared via twitter in real-time. Developers will come away with a better understanding of how Neural Machine Translation works, how to build pipelines for machine translation preprocessing tasks and Neural Machine Translation models, and have access to a demo repository to experiment with and build machine translation models themselves.

Bring Your Camera into 2018: Forward Porting Image Sensor Drivers - Jacopo Mondi, Renesas
The Linux media community tried in the past to ease the work of camera driver developers by providing frameworks and methods to abstract away from the crude V4L2 APIs. Some of those frameworks, as the 'soc_camera' one, have served their purpose so well they are often found in most BSPs and non-mainline camera drivers.

In the forthcoming Linux kernel releases said framework will be obsoleted, and developers of BSPs and downstream kernels will find themselves in the need to port their existing drivers. This presentation aims to provide them an overview on how to better do that while presenting how sensor drivers are expected to evolve as the hardware complexity image capture subsystems in embedded devices keep increasing year after year.

Building Safe Systems with Linux - Nicholas McGuire, OpenTech
With the increasing complexity of technical systems, as in autonomous robotic systems, the functionality of safety-related systems is dramatically changing and calling for elaborate capabilities, while at the same time demanding a high level of assurance. Linux is on the shortlist of many projects now due to its utility, its security capabilities, and its versatility, but can it be safe? It can be answered by assessing conformance to current functional safety standards. Defining and developing adequate methodologies for a safe Linux-based system was the goal of OSADL's SIL2LinuxMP project. Based on three years of work on SIL2LinuxMP at OSADL, Linux is a suitable candidate for complex safety-related systems.

The challenge is mapping the intent of functional safety standards to the concrete properties, capabilities, and limits of Linux. This talk shows the project's approach to compliance.

Keeping Up With The Joneses (CVEs) - David Reyna, Wind River Systems
Keeping up to date with security issues once a product has been released isn’t as easy as it first seems. There’s a well-known database of all security issues hosted by MITRE, but the data isn’t reliable enough to be trusted blindly. You could upgrade to the latest release of every software package you ship, but packages may be unmaintained or introduce new bugs. There is essentially no silver bullet for the problem of security updates.

In this presentation, we will explain why the obvious solutions are flawed, what the alternatives are, how best practises can be shared to reduce the time between fix announcement and deployment, and discuss how best to handle keeping up to date with security issues.

Story of a Kubectl Command - Indradhanush Gupta, Kinvolk
Kubernetes for the most part feels like a magical black box that knows how to fix your problems for you. However as Indradhanush himself found out one day while hacking on Kubernetes that understanding what goes on behind the scenes not only helps to debug tricky scenarios but design better solutions for the Kubernetes ecosystem.

In this talk, he will help shed the mystery behind the "kubectl" command that appears to magically manage our services. He will take the audience on a tour of the Kubernetes architecture describing the role of each component and look at how authentication and authorization checks are done on a command before accepting and persisting the state into Kubernetes. Indradhanush will also talk about the role of the kubelet and the container runtime in managing pods and finally about networking in Kubernetes for communication across nodes.

Everything You Need to Know to Submit a Linux Kernel Patch! - Sayli Karnik, Credit Suisse
Kernel hacking can be daunting to open source beginners. The aim of the session is to shatter this myth and help coders to get started with contributing to the Linux kernel. Having interned with Linux kernel previously and more than 50 of my patches merged into the kernel, I have a decent understanding of the nitty-gritty in this area. The session will cover A to Z steps ranging from setting up the development environment to creating a sample patch using version control, to sending the patch to the concerned maintainers. It will emphasize good patch practices and common coding convention mistakes that get valuable patches rejected. I will mention examples of areas in Linux subsystems that can be patched as starters. For eg., checkpatch.pl script can be used to detect bugs in coding styles/resolving TODO's.

The delight of getting your first patch merged can match none other!

You can expect to learn more about the people, their employers, and other data that impacts how people participate on the mailing lists. For example, do timezones influence collaboration? How about source code contributions? An early look at this data was presented last year, but more results are available after another year of research, so this session will draw examples from different subsystem mailing lists and explore new results.

Introducing OpenFaaS Cloud, a Developer-Friendly CI/CD Pipeline for Serverless - Alex Ellis, OpenFaaS project / VMware
Serverless functions are about iterating faster, but users are having to create their own complex solutions to get functions into production.

This talk introduces OpenFaaS Cloud - a portable CI/CD pipeline that enables a GitOps experience as originally popularised by Heroku. As a user no Docker or Kubernetes knowledge is required, you just “git push and get functions”. A cloud-native toolset will build, test, push and deploy your functions. A GitHub App gives native integrations into GitHub which automatically updates commit statuses when your functions are ready.

OpenFaaS Cloud focuses on useability with a built-in dashboard and security using CNI NetworkPolicy to isolate functions, CertManager for HTTPS and Bitnami SealedSecrets to enable any secret to be stored in a public GitHub repo. You can use your own cluster, a managed Kubernetes service or the free community-supported cluster.

Productionizing ML Pipelines with the Portable Format for Analytics - Nick Pentreath, IBM
The common perception of machine learning is that it starts with data and ends with a model. In real-world production systems, the traditional data science and machine learning workflow of data preparation, feature engineering and model selection, while important, is only one aspect. A critical missing piece is the deployment and management of models, as well as the integration between the model creation and deployment phases.

In this talk I will introduce the Portable Format for Analytics (PFA) for portable, open and standardized deployment of data science pipelines & analytic applications. I will also cover open-source work we have done to support export of Apache Spark ML pipelines to PFA, as well as explore PFA export for other popular ML frameworks (such as scikit-learn). Finally, I will compare and contrast PFA to other available alternatives including PMML, MLeap, ONNX and Apple’s CoreML.

Cooking a Debian System: One, Two, Debos! - Ana Guerrero López, Collabora
Customized Debian images can now be created in a quick and reproducible way!

In the Debian world, there are many ways to build images, but none of them are generic enough to allow highly customized systems for different use cases or embedded systems, which usually require a significant amount of customization and optimization.

Traditionally, developers often end up using debootstrap, which works by
downloading the .deb files from a mirror and unpacking them into a directory which can eventually be chrooted into. Then, after deboostraping the base system, you tend to make some customizations on this image, install some extra packages, run a script, add some files, etc. debos is a tool to make these kinds of trivial tasks easier.

During this talk, we'll look at how debos works and provide some use cases, and we'll give an overview of how to easily create customized Debian images.

Spectre and Meltdown vs. Real-Time: How Much do Mitigations Cost? - Ralf Ramsauer & Wolfgang Mauerer, OTH Regensburg; Jan Kiszka, Siemens AG
2018 had a bumpy landing with the disclosure of hardware vulnerabilities in microprocessors. With Spectre and Meltdown leading the way, they enabled attackers to read private data from kernel and user space. Since then, several other hardware bugs were revealed.

Lower level system software such as operating systems or hypervisors needs to implement countermeasures to the vulnerabilities. The fixes come at a cost, particularly in execution time. Embedded real-time environments have a strong focus on low latency and determinism and may be affected by those fixes.

What’s the mitigation cost and impact on typical real-time applications? To answer these question, we use benchmarks as well as a set of microbenchmarks to quantify the consequences of the mitigations. Our targets are real-time operating systems, such as the Preempt-RT patch for Linux as well as embedded real-time hypervisors.

Are You Insured Against Your Noisy Neighbor? - Sunku Ranganath, Intel
Traditional NFVi dataplane performance benchmarking and testing rarely focuses on availability and consumption of resources such as CPU Cache and Memory Bandwidth. Quality of Service fine tuning, without considering such resources, often leads to problems such as over-subscription and shared resource contention - often termed as noisy neighbor effects. This work focuses on mitigating noisy-neighbor effects with the efficient management of such resources.

We present the methodology and test scenarios using opensource solutions - OPNFV-VSPERF, Collectd, Stress-NG, and RMD-client - for (a) analyzing the performance impact due to the presence of noisy neighbors and (b) controlling access to Last Level Cache (LLC) to achieve optimal performance. The presentation will cover the creation and analysis of LLC profiles of all workloads, and policy-driven management of LLC resource to improve the performance and manage the noisy neighbors.

Data Mobility for Kubernetes Persistent Volumes - Xing Yang, Huawei
While it is unusual for a public cloud to be down, it had happened in the past. How to make sure your data is always available if you are running Kubernetes in one of the public clouds?

The multi-cloud data engine powered by OpenSDS, an open source project under Linux Foundation, provides a solution for this problem by migrating and replicating data across multiple clouds (whether it is public or private), so your data is always available somewhere even if one cloud is down. In this session, Xing will discuss the snapshot support in Container Storage Interface (CSI) and Kubernetes, and how that can be leveraged by the multi-cloud data platform powered by OpenSDS to achieve data mobility for Kubernetes Persistent Volumes.

From One Architecture to Many: Porting OpenMandriva to AArch64, armv7hnl, RISC-V and Ryzen - Bernhard "Bero" Rosenkränzer, OpenMandriva
OpenMandriva - a desktop-centric Linux distribution - has been around (under different names, starting with Mandrake Linux) on x86 machines since 1998 - but with ARM machines rapidly getting to speeds where they can make good desktops, and first boards using the open RISC-V architecture becoming available, being an x86 distribution wasn't good enough - OpenMandriva Lx4 will be released for AArch64 (64-bit ARM) and armv7hnl (32-bit ARMv7 with NEON FPU), and a RISC-V port is in the works.

Also, Ryzen processors have emerged as an x86 CPU that can benefit from different optimizations than a typical Intel box, and we're taking up the challenge of building a special spin optimized for those processors.

This talk shows what we had to do in order to get from x86-only to supporting most interesting architectures, problems faced, and how to overcome them.

Scaling Your Developer Community via Plugins - Greg Sutcliffe, Red Hat
Finding developers to work on your project is hard. Most growth in developer communities is organic - that is, they find you and decide to contribute - which is fine, but perhaps there are other ways to get people involved?

In this talk, Greg will use his experiences of developing plugins for a project as a way to enable more contribution. Users frequently encounter the "last mile problem" in which a project solves 90% of their issue, but they want the flexibility to fix the rest. Plugins enable motivated users to fix their own issues, and a good plugin architecture encourages them to share that plugin with other users. In effect, they become a part of the developer community, invested in it's growth.

We'll look at the pros & cons of supporting plugins, ways in which you can share plugins, maintainer strategies, and more, drawing on examples from communities like TheForeman, config management, Discourse, and more.

A Hybrid Solution to Address Real Time Virtualization - Tiejun Chen, VMware
Virtualization technologies has already been deployed in the embedded systems but in many use scenarios, applications/services should be responded in real time. Some typical hypervisors are constructed to be a real-time hypervisor but this solution still cannot meet hard time requirement, even real-time guest OS is adopted. Because hypervisors have no knowledge of tasks inside VM actually. So based on this two levels of scheduling domain, I'd like to discuss-to review #1. What are those challenges, #2. Benefits with Real-Time virtualization; #3. Several potential but different approaches to construct real-time virtualization solution: 1:paravirtualize guest OS like Linux to sync scheduling between GOS and hypervisor ;2: mmu isolated approach; 3:single-process purpose OS; 4: AMP approach; and then we provided a hybrid solution to meet real-time virtualization and edge computing with some potential use cases.

Civil Infrastructure Platform: Two Year Experience of Industrial Grade Open Source Base-Layer Development - Yoshitake Kobayashi, Toshiba Corporation & Urs Gleim, Siemens AG
The Civil Infrastructure Platform (CIP) is creating a super long-term supported (SLTS) open source "base layer" (OSBL) of industrial grade software that will enable the implementation of building blocks in civil infrastructure projects. Currently, all of these systems are built from scratch, with little re-use of existing software building blocks, which drains resources, money and time.

A Full Stack Journey to Reach Efficient Container Storage Cloning - Niels de Vos, Red Hat
With the adoption of more diverse workloads and applications in containers, demands for enhanced features become clear. Some of these features are related to the persistent storage of the contents the applications consume.

In this talks, Niels will go through some of the expectations that a Kubernetes application like KubeVirt has from a storage environment. This includes a scalable approach to cloning new virtual machines from template disk images. While just copying the data from one PVC or volume to an other is possibly, this is not very efficient.

This particular journey towards efficiently cloning disk images is driven by KubeVirts Containerized-Data-Importer project, with stops at Kubernetes Storage Provisioners and Linux kernel filesystems on a solid Gluster road.

BoF: Computer Science Education and Diversity - Laura Reddy, Cisco; Emma Foley & Thaynara Silva, Intel
A Birds of a Feather discussion on diversity in STEM careers and what we can do to get more kids choosing to study these subjects. Giving updates about what is happening in the different countries and some of the programs we've been involved in to try to further this. This is a follow up on our previous talk at last year's conference.

No one can deny that computer science education is an important topic that is often overlooked by those who set the curricula, and it usually fall to professionals and company outreach programs to give children their first taste of coding. This approach can put more pressure on programmers at a time when the tech industry is starved of new talent. We're trying to pump up the pipeline, while trying to more forward in an under resourced industry.... this is what children will see, and that isn't a good influence.

BoF: Early Platform Drivers in Linux Kernel - Bartosz Golaszewski, BayLibre
Certain class of devices, such as timers, certain clock drivers and irq chip drivers need to be probed early in the boot sequence. The currently preferred approach is using one of the OF_DECLARE() macros. This however does not allow the users to benefit from many helpful APIs exposed by the kernel that only work with actual device drivers (ones that deal with struct device * objects).

There were several attempts at solving this issue in the past. Some of them were merged only to be abandoned later. I recently posted series of patches that were initially aimed at solving an initialization problem on a client's platform but grew into a full fledged early platform drivers implementation.

During this BoF session I'd like to start a discussion about how to best handle devices that need to be probed early in linux.

BoF: Thanos - High Availability and Long Term Storage of Prometheus Metrics - Bartek Plotka, Improbable
Prometheus has been thriving for several years. However, some questions were still largely unaddressed to this day. How can we store historical data at the order of petabytes in a reliable and cost-efficient way? Can we do so without sacrificing responsive query times? And what about a global view of all our metrics and transparent handling of HA setups?

Thanos takes Prometheus' strong foundations and extends it into a clustered, yet coordination free, globally scalable metric system. It retains Prometheus’s simple operational model and even simplifies deployments further. Under the hood, Thanos uses highly cost-efficient object storage that’s available in virtually all environments today. By building directly on top of the storage format introduced with Prometheus 2.0, Thanos achieves near real-time responsiveness even for cold queries against historical data.

BoF: Landscape and Use Cases for OSS-based Compliance Tooling - Michael Picht, SAP SE & Michael Jaeger, Siemens AG
During the recent years, as OSS gained more and more importance, the compliance community has come up with a number of OSS-based tools. Nowadays, for different tasks in license compliance a selection of different mature tools is available.

To understand which tools are available for which purpose, how they can interact and how they align and integrate in a generic dev ops scenario, we propose a structured approach and create a landscape of functional blocks that are required for compliance tooling.

We see this initial contribution to kick off a discussion about the OSS-based tooling landscape. The discussion will be focused for the identification of overlap and as well as current gaps, which is important for consolidation. Therefore, the session proposal is to present the landscape in the beginning and then start a discussion, gather feedback and collect ideas from the audience.

DMA Safety in Buffers for Linux Kernel Device Drivers - Wolfram Sang, Renesas / Consultant
This talk is about findings which originated from an issue in the I2C subsystem but then became more widespread. The question was if externally allocated message buffers for the I2C subsystem need to be DMA safe. That gained importance and needed a proper solution.

While working on this, buffer handling in other subsystems was evaluated regarding DMA safety. It turned out that some, including I2C, work rather by coincidence or, at least, on assumptions which are likely to be true, but not always. And those assumptions might even be less likely true in the future, given some structural changes kernel hardening brings.

Learn that a check if buffers are DMA capable is surprisingly not an easy task. And find out which solutions exist as of today. With safety being an increasing interest for embedded, more eyes are needed for this problem.

EBBR: Standard Boot for Embedded Platforms - Grant Likely, Arm
Booting and embedded systems are not always simple. Even though most platforms have U-Boot firmware, each one has slightly different behavior with regard to installing and booting an OS. In addition, the embedded boot flow uses entirely different interfaces when compared to the general purpose server and desktop ecosystems. All this adds up to requiring custom enablement for each platform, which is not viable for most OS distribution projects.

The Embedded Base Boot Requirements (EBBR) project is a new effort to define a standard for booting embedded platforms that is supportable by the existing OS ecosystem. EBBR specifies a subset of the UEFI standard that can be implemented with upstream U-Boot and takes into account design patterns common on embedded systems. In this session, we'll discuss the goals of the EBBR project, the state of the EBBR document right now, and the progress to creating EBBR reference platforms using existing QEMU models and popular development boards.

The Seven Year Leap - Updating a Product from Linux 2.6 to 4.15, a Real-World Project Case Study - Ed Langley, Kobilon
Many Linux devices actively developed/maintained out there for niche markets are still running a 2.6 series kernel. Backporting becomes a regular habit, but often updating the kernel is deemed too risky.

In this talk, Ed Langley will discuss a real-world project in which he did just that - update a single purpose OMAP3 based Android device from 2.6.37 to 4.15.

What issues in the project finally led to the upgrade? How was the effort estimated? Convincing upper management to go ahead, task breakdown and planning out the approach.

On the technical side: What just worked, and what did not, what used to require a separate driver 7 years ago, and is now accomplished in 3 lines of a dts file. Closed source GPU driver woes, and fun with running 4.15 whilst trying to stick with Android KitKat. Yes, you can run old Android on a new kernel!

Debugging Embedded Devices Using GDB - Chris Simmonds, 2net (Additional Track Registration Required)
Bugs happen. Identifying and fixing them is part of the development process. This tutorial demonstrates one of the key tools in the embedded Linux developer’s toolbox: the GNU Debugger, GDB.

You will begin by using GDB to debug a program running on a target device. You will learn about debug symbols, how to launch a program on the target using the GDB proxy agent, gdbserver, and how to set up communication between GDB and gdbserver. Then, you will be able to perform basic debugging tasks, including setting breakpoints, stepping through code, examining variables and modifying variables. After that, you will learn about GDB command files and how they can help you by automating certain tasks. You will receive a handy GDB cribsheet to help you with all of this. If time allows, we will discuss how to use GDB to analyze core dumps so that you can perform a post-mortem on a crashed program

Grabbing Audio and Video on a Board Farm - Krzysztof Opasiak, Samsung R&D Institute Poland
Running a test lab usually has two purposes: automated tests and sharing boards among developers. For many use cases accessing a board over serial console and being able to boot a custom kernel is enough. But what if you develop multimedia drivers or apps and their QA requires grabbing audio and video output from your board?

Krzysztof starts his story with a gentle introduction to MuxPi: open hardware board which allows unified remote access to (almost) any Single Board Computer. The most important features and limitations of this board are presented in this part. Next, he shows how to extend it with audio and video capture capabilities using a cheap ($30) HDMI extender and provide this stream to remote machine. Then the story goes to human input emulation and integrating whole solution into single convenient open source app. Finally there is Q&A session and hopefully some discussion.

Large Scale Deployments for Automated Kernel Testing - Dave Pigott, Linaro
The Linaro Automated Validation Architecture, or LAVA for short, allows users to test kernels, modules, root filesystems and applications in an automated way, allowing systems to look for regressions, improvements, all under the test writers control. The Linux Kernel Functional Test (LKFT) deployment was built on our experience of large automated deployments, and even more lessons were learned as a consequence. This presentation focusses on that deployment and it’s wider implications for others wishing to deploy LAVA.

The requirements for rapid turn around of results means that many devices of a particular type need to be available, and this presents challenges in reliability, control and space utilisation.

The performance was compared with a Cortex-A9, a 10+ stage out-of-order pipeline. Even with the difference in pipeline design in these two processors, it is an interesting comparison because it represents the evolution of Xilinx’s ZYNQ product line.

Three different latency tests were performed: standard cyclictest latency, external hardware interrupt latency (as utilized by the IIO subsystem) and Ethernet UDP latency. Analyzing the performance of a hardware interrupt can be tricky, the method of utilizing a timer with a capture function is detailed in the presentation.

Creating an IoT Data Layer for Collecting, Storing, Analyzing and Reacting to Data - David G. Simmons, InfluxData
While the IoT has always been about 'Things' it is more and more about the data that those things generate and how that data is collected, stored, managed, analyzed and acted upon that is moving to the fore. The ability to collect data from a variety of sources, store -- and forward if necessary -- data at any point across the entire architecture, whether that be at the edge or in the cloud, is critical in developing a Data Layer for the IoT. What the IoT needs is the ability to collect, store, manage, visualize, analyze and respond to data at any point across the architecture without regard to the underlying compute hardware. In this talk I'll discuss building an entirely Linux- and open source-based IoT data layer that is capable of all of these things from Edge to Cloud and everywhere in between.

Keynote: Exceeding Diversity and Inclusion Goals to Fuel Open Source Growth - Johanna Koester, Program Director of Developer Technology and Advocacy, IBM
Diversity and inclusion are more than a checkbox; it’s fuel for open source community growth and success. While we have seen great progress for diversity in the form of center stage presentations and focused meetings at most tech events, the reality is that there is still more to be done drive effective inclusivity of those diversity groups.

Through the stories of successful open source contributors from under-represented groups, Johanna’s keynote will celebrate the best practices that have enabled the success of these individuals and then provide recommendations to further drive inclusion in any technology community. Open source communities have shown the world that when we bring together members of multiple companies and diverse backgrounds, we can achieve far more than working apart. It’s for that reason that open source communities today have a great responsibility to continue advancements for inclusion not only to fuel their own success but more importantly to model the benefits of inclusion to the world.

Keynote: Digital Echoes: Understanding Patterns of Mass Violence with Data and Statistics - Patrick Ball, Director of Research, Human Rights Data Analysis Group
Data about mass violence can seem to offer insights into patterns: is violence getting better, or worse, over time? Is violence directed more against men or women? But in human rights data collection, we (usually) don’t know what we don’t know – and worse, what we don’t know is likely to be systematically different from what we do know.

This talk will explore the assumption that nearly every project using data must make: that the data are representative of reality in the world. We will explore how, contrary to the standard assumption, statistical patterns in raw data tend to be quite different than patterns in the world. Statistical patterns in data tend to reflect how the data were collected rather than changes in the real-world phenomena data purport to represent.

Using analysis of mortality in Chadian prisons in the 1980s, killings in Iraq 2005-2010, homicides committed by police in the US 2005-2011, killings in the conflict in Syria, and analysis of genocide in Guatemala in 1982-1983, this talk will contrast patterns in raw data with estimates of total patterns of violence – where the estimates correct for heterogeneous underreporting. The talk will show how biases in raw data can -- sometimes -- be addressed through estimation. The examples will be grounded in their use in public debates and in expert testimony in criminal trials for genocide and war crimes.

Common Attacks on IoT Devices - Christina Quast
The importance of securing embedded devices has become clear to the whole industry as they started to play a bigger role in our daily lives in recent years. Up to now, it has been easy to compromise IoT devices such as vacuum robot, IP cameras, smart home devices, etc.

In the early days of IoT, attackers could often succeed without having physical access to the device.
By now more and more OEMs took steps to improve the defenses of their devices, which in turn has led the attackers to improve their strategies. Among others, the possession of a potential target is often times a necessity for a feasible attack.

This talk will shed light on the landscape of recent attacks on IoT devices. This enables the discussion of common pitfalls in designing embedded systems in order to raise awareness for this topic.

Firmware Transparency: Open All the Way Down - Josh Triplett, Intel
Many system-on-chip devices include coprocessors and other components to manage or accelerate various platform functions; some of these components run before the OS or BIOS, orchestrating system configuration and bring-up. However, these components rarely provide Open Source firmware or document their functions, and other low-level firmware treats them as opaque. This talk presents the initial version of Open Source firmware for SoC components, in an effort to improve the transparency and trust of the platform.

Josh will show the development and progress on both the firmware, the associated tooling, and the challenges of the development and debugging environment. Josh will also show how reproducible builds allow anyone to audit the binary firmware image and confirm that it corresponds to the source code.

Managing Linux Kernel Configurations with Config Fragments - Darren Hart, VMware
With well over 10,000 unique configuration options it can be difficult to make your Linux kernel configuration a deliberate one. Each new version introduces new options, renames some, and removes others. A static config is convenient at first, but it doesn’t distinguish between deliberate choices and the defaults, making it difficult to evaluate changes and prepare for upgrades. Configuration fragments have been part of build systems like the Yocto Project for years, and later became more common with the addition of the merge_config.sh script to the upstream Linux kernel. Darren will explore the complex task of Linux kernel configuration management through some common scenarios and pitfalls, and show how granular configuration with fragments provides for a more deliberate and more manageable approach to Linux kernel configuration management.

How to Avoid Writing Device Drivers for Embedded Linux - Chris Simmonds, 2net
Writing device drivers is time consuming and error prone. The good news is that in most cases you don't have to because Linux provides ready-made drivers for common types of interface. If you want to twiddle some GPIO pins, fade the brightness of an LED or read the temperature using a chip you got from Adafruit, it is all done for you. Well … almost all: you still have to write some user-space code to call the generic driver.

In this presentation I will give examples using three subsystems: GPIO, PWM and I2C. For each one I will show you how to write code to control hardware from the safe and simple environment of your application, written in C or C++ (bindings for other languages exist). If all goes well, there will be live demos of each category.

The New Wi-Fi Experience for Linux - Marcel Holtmann, Intel
With the introduction of the open source wireless daemon iwd, the Wi-Fi experience for Linux has changed. It became necessary to replace wpa_supplicant and create a complete system for managing Wi-Fi for Linux in a single place. Almost 2 years later iwd has succeed and implemented features and functionality that was previously not available on Linux. This presentation focuses on the recent development and how iwd has been integrated into existing platforms using NetworkManager and ConnMan or how it fits into ChromeOS. With iwd the seamless and fast roaming is no longer something that has only been seen on non-Linux platforms. It has kept up with recent 802.11 standard development and Wi-Fi Alliance updates. The development of iwd led to new kernel interfaces to help improve the user experience and simplify Wi-Fi for Linux.

Preventing CPU Side-channel Attacks with Kernel Tracking - Marian Marinov, SiteGround
Updating microcode and losing performance, because of that update is a big concern for everyone. So Marian will show his team's work on how they decided to fight the attacks and what their solution gives and what it lacks.

The team's point is that there is no valid case for a child program or thread to keep dying and this is what is primary technique for executing cache side-channel attacks.

So monitoring dying processes allows for marking processes that try to attack us.

Marian will provide examples and demo of their prevention mechanism.
He will also share the team's work on how they have used TSX instruction statistics to check for TSX based cache side-channel attacks.

As a side effect, this protection mechanism can help mitigate(somewhat) all attacks that use this kind of attack vector.

Revitalizing Open Source Contributions and Participation across Mozilla - Daniel Izquierdo, Bitergia & Riccardo Iaconelli, Mozilla
In 2017, Mozilla embarked upon an effort to revitalize open source contribution and participation across the organization. Working with Bitergia, we analyzed 16 years of contribution data, ran surveys, and spoke with both employee and non-employee contributors.

A key finding was that while Mozilla was fully committed to OSS co-development, we didn't have a common framework to help us talk about how OSS project differs in terms of goals, environment, and resourcing. Our one-size-fits-all mental model meant we didn't always set correct expectations around a project or commit appropriately.

This presentation will show the work done with Bitergia to gain a more thorough understanding of what OSS contribution at Mozilla looks like and the Open Source Archetypes, which are a loose definition of OSS models as found in the wild, which we created with the help of Open Tech Strategies.

Introducing FfDL - Deep Learning as a Service on Kubernetes - Animesh Singh, IBM
Training deep neural network models requires a highly tuned system with the right combination of software, drivers, compute, memory, network, and storage resources.

Deep learning frameworks such as TensorFlow, PyTorch, Caffe, Torch, Theano, and MXNet have contributed to the popularity of deep learning by reducing the effort and skills needed to design, train, and use deep learning models. Fabric for Deep Learning (FfDL, pronounced “fiddle”) provides a consistent way to run these deep-learning frameworks as a service on Kubernetes.

In this talk we are going to introduce an open source project called Fabric for Deep Learning (FfDL). It uses a microservices architecture to reduce coupling between components, keep each component simple and as stateless as possible, isolate component failures, and allow each component to be developed, tested, deployed, scaled, and upgraded independently.

Collaboration is the Better Way - Erik Riedel, Dell EMC & Lauri Apple, Workday
Do you wish that your teams were more productive? Do you struggle with deadlines & product quality? Are you missing market opportunities because of late delivery? Are you unsure why there is turnover among your most effective staff? Do you see the benefits that open source participation & collaboration brings to other companies, but are unsure how it could apply to you & your organization?

This session will present a set of specific examples & stories from our direct experience of the benefits of open collaboration to enable more productive & effective teams.

We believe that the desire to assist each other & to collaborate is often present but unrealized. Many teams have established systems & styles of communication that limit opportunities for creative interaction, reduce flexibility, & ultimately restrict effective business results.

The session will include hands-on exercises for participants to learn-by-doing.

SPI Memory Support in Linux and U-Boot - Miquèl Raynal, Bootlin
For a long time already, SPI memories have been supported in Linux and U-Boot. They were relatively small and slow (like dataflash and EEPROM) but the new trend in the embedded world is now leaning towards fast SPI NOR and SPI NAND devices which people tend to use as their main storage.

In this talk Miquèl will present how those devices work and how you can get the best performance out of them by using advanced SPI modes like Dual or Quad SPI. He will also talk about the rework he did in Linux and U-Boot to be able to support all kinds of SPI memories (SPI NOR, SPI NAND, SPI SRAM) using the same SPI controller driver and still be able to benefit from advanced features (like direct mapping) provided by some SPI controllers.

Building Stable Trees with Machine Learning - Sasha Levin, Microsoft & Julia Lawall, Inria
Building stable trees is difficult; we are required to find only commits that fix bugs (needle) in the massive flow of commits that go upstream (haystack).

Currently the process is based on authors and maintainers tagging their commits properly and helping stable maintainers to know that they should be picking up these patches.

However, this doesn't always happen right. Commits get lost, forgotten, or never looked at to begin with. This means that important fixes are being left out of stable trees and not reaching the users who rely on stable trees for fixes.

This talk with go over a new approach to detect bug fixing commits in the kernel tree using machine learning, and demonstrate how it was used to submit over a thousand commits to various stable trees.

Elivepatch: Flexible Distributed Linux Kernel Live Patching - Alice Ferrazzi & Takanori Suzuki, Cybertrust
“Elivepatch” addresses the limitations and shortcomings of the current distributed live patching services as follows:
• 3rd-party trust: Trust on a third-party service can be eliminated by deploying Elivepatch in-house.
• Custom kernel configurations: Live patches can be created for different kernel versions and configurations by varying the parameters to Elivepatch.
• Modified kernels: Support is extended to locally modified kernels (e.g. out-of-tree patch sets) by sending the server a list of patches that should be applied before the live patch creation process starts.
• Client-generated patches: In Elivepatch, clients specify the live patches to be created whereas current systems only support vendor-generated patches.
• Security auditing: Elivepatch is completely open source and thus fully auditable.
We will also talk also about future ideas:
• Porting to different distributions
• Livepatch CI/CD testing

Making Community Decisions without Consensus - George Dunlap, Citrix Systems R&D UK Ltd
Healthy open-source communities usually include a wide range of people with very different ideologies, goals, values, and points of view; from anarchists to CEOs of major corporations. The normal approach for making decisions that affect the entire community should be an attempt to reach consensus through discussion. But what if you're attempting to make a decision which is critically important, but for which you know there are irreconcilable differences in the community?

The XenProject community had such a decision to make in the wake of the XSA-7 security issue. This talk will cover the approach we took which (we think) allowed us to find a "center of gravity" for the community, and allowed everyone to feel that their viewpoint was considered, in the spite of the lack of any option with clear consensus. We hope this will help other communities navigate similarly difficult waters.

How to Use Kubernetes for Production Grade Edge Computing - Steven Wong, VMware
Some applications benefit from moving closer to data ingest, or the user. Edge reduces local processing latency, and supports isolated operation. It also has challenges compared to the pooled resources, and single point of management of centralized clouds.

You won’t achieve the Google Borg experience at an edge location - nor are you likely to need it. But with planning it is possible to achieve edge deployments that are secure, with predictable performance and “highly available enough” considering constraints on money, physical space, power, etc.

Steve will provide specific recommendations related to architecture, networking, storage, patching, logging, disaster recovery, and remote manageability - based on using Kubernetes, and other open source tools and technology.

This is a rapidly changing space, and Steve will also touch on some interesting proposals and work underway in the space.

Machine Learning Made Easy on Kubernetes. DevOps for Data Scientists - Brian Redmond, Microsoft
Though machine learning and AI are immensely powerful, these solutions are by no means easy. In many cases, there are many diverse components that are not designed to work together. Additionally, these models are most efficient when running on large scale clusters that can be more difficult to manage. Configuration and deployment is often left to data scientists who are wasting time on infrastructure and not on data science itself.

Kubernetes to the rescue! In this session I will talk about how machine learning can be greatly improved by implementing ML solutions on top of Kubernetes with containers. I will include demos of big data and machine learning workflows with solutions such as Kubeflow (Tensorflow, JupyterHub), Apache Spark, and Kubernetes of course.

Debian & Yocto: State of the Art - Kazuhiro Hayashi, Toshiba Corporation & Manuel Traut, Linutronix GmbH & Baurzhan Ismagulov
For building Linux-based products, combining benefits of existing distributions and tools becomes essential. Debian is the platform of choice for industrial and other products requiring continuous security updates and 10+ years of maintenance. Product builders need an integrated, flexible, easy-to-use toolkit for building product applications, patching Debian packages, and generating and customizing the root filesystem image.

ELBE, Isar, and Deby use Debian as the base system. The projects are working together towards a common solution. The approach is to provide tooling for package building, customization and release management based on Yocto build tools, structure, and workflows. In this talk, we will introduce why the projects joined efforts, what kind of functions are required for satisfying product demands, and how the functionality could be implemented with bitbake recipes.

Linux and Zephyr “Talking” to Each Other in the Same SoC - Diego Sueiro, Sepura / Embarcados
SoC vendors are launching Hybrid Multiprocessors (HMP) architectures where one or more cores deal with the end-user application and other cores implement specific features. Instead of battling with Linux Kernel to meet the real-time constraints, you can defer the “dirty” work to a microcontroller in an isolated and controlled environment and it is where Zephyr excels.

It is important that hybrid cores communicate with each other to meet the application requirements. The RPMsg can be used in these kinds of arrangements exposing an API independent of the underlying inter-core communication.

In this presentation, Diego Sueiro will talk about how Linux and Zephyr can share data using RPMsg, initialization flow, and configurations needed to enable its communication.

Main topics of this session:
  • Real-Time applications with HMP
  • RPMsg on Linux
  • Enabling RPMsg-lite on Zephyr
  • Demo
  • Future work

Teaching your Test Framework to Speak LAVA - Tim Orling, Intel Corporation
You already have tests, and you want to use LAVA, the popular automated test automation framework. Now you have to rewrite them to work in LAVA? Instead, teach your testing framework to output the signals LAVA understands to get more benefit from the LAVA dashboard. A simple technique transforms a one-line “pass/fail” result for your entire test suite into individual test case results. This enables the use of queries and charts built-in to the LAVA dashboard. We will show examples of how to do this in several unit testing frameworks, such as pytest, unittest, and BATS.

How do you create a secure cloud management layer for application teams without loss of productivity and agility?

Learn how to take the operations team on a journey of automation and how the organization looks like after hiring engineers to develop those capabilities following SRE model.

Migrating applications to Cloud services creates a model of shared responsibility between the customer and Cloud Service provider (CSP). This shared model can help relieve customer’s operational burden as CSP operates, manages and controls the components from the host operating system and virtualization layer down to the physical security of the facilities in which the service operates.

Toro Kernel, A Dedicated Kernel for Microservices - Matias Vara Larsen, Silicon Gears & Cesar Bernardini, Barracuda
Current cloud infrastructure allows to implement cheap microservices by using VMs and/or containers. When a cloud-based architecture is chosen, microservices are deployed on VMs which are guests that run a General Purpose OS. In this context, we have identified two drawbacks: first, the unnecessary overhead due to the use of a General Purpose OS to run a dedicated application. Second, too many context switches due to the use of several microservices. These main issues prevent cloud architectures to scale well because of multiplying VMs. In this talk, we present Toro a dedicated kernel to run microservices. In Toro, the kernel and the microservices are compiled together which results in a image that can be deployed in a cloud provider. This talk presents Toro by focusing on how the kernel has been optimized to better support microservices.

Coccinelle: 10 Years of Automated Evolution and Bug Finding in the Linux Kernel - Julia Lawall, Inria
The Coccinelle C-program matching and transformation tool was first released in 2008 to facilitate specification and automation in the evolution of Linux kernel code. The novel contribution of Coccinelle was that it allows software developers to write code manipulation rules in terms of the code structure itself, via a generalization of the patch syntax. Over the years, Coccinelle has been extensively used in Linux kernel development, resulting in over 6000 commits to the Linux kernel, and has found its place as part of the Linux kernel development process. This talk studies the impact of Coccinelle on Linux kernel development and the features of Coccinelle that have made it possible.

Fun with Dynamic Kernel Tracing Events - Steven Rostedt, VMware
Static tracing events have been in the kernel since Linux v2.6.31. They are extremely useful, and today with over 1000 static events in the Linux kernel, they are common and well known. Even with so many events, there's always something else in the kernel that one would like to know about. This is where dynamic events can become handy. Not as well known are kprobe events. These are events that can be created dynamically, and have been available since v2.6.33. But they can be difficult to use, and change from kernel build to kernel build. Coming soon are function based events, where they are tied to the function tracer, and you can created events based on function arguments. This talk will discuss the crazy things you can do with function based events as well as kprobe events.

Beyond Burnout: Caring for Your Employees’ Greatest Asset - Leslie Hawthorn, Red Hat
As an industry, tech is now having much more open conversations about topics beyond bits and bytes: creating psychological safety, promoting diversity and inclusion, and addressing burnout. Underlying each of these topics is a conversation that is much more difficult to have; how can our industry and our workplaces best support our employees’ mental health?

Drawing on her personal experience and sharing the (anonymized) stories of other technologists, Leslie Hawthorn will share her own story of creating a successful career while battling chronic depression. Her talk will focus on developing processes in your workplace that support employee mental health and how management can create an inclusive culture that accommodates those who require mental health care. Her goal is to have everyone leave better equipped to care for their employees, co-workers, teammates, and fellow humans’ greatest asset: their minds.

The Great Debate: Is There An Open Source Business Model, YES or NO? - Jeffrey Borek, IBM & Stephen Walli, Microsoft
The open source definition is over 20 years old. Red Hat is a multi-billion dollar company. MySQL and JBoss have had great acquisition exits. Cloudera and Hortonworks are well on their way to becoming the next billion-dollar software companies. But Stephen would like to observe that despite these successes, there is NO open source business model. 

But wait, Jeffrey would beg to differ! From data centers to the cloud, from self-driving cars to drones - open source software is everywhere. Major companies that are bottom-line driven are starting to actively engage and contribute to open source projects. 

Join this lively session with Stephen and Jeffrey as they compare and contrast the current state of the OS ecosystem, share their unique point of view, and debate what is and what comes next.

Playing Nicely Together: Large Scale Open Source Program Strategies - Jeffrey Osier-Mixon, Intel
This presentation discusses the development of a generic, universal strategy for guiding the collective enthusiasm of over 100k employees in creating and participating in open source projects.

Launching a single open source project is a wonderful thing to bring into the world, but like all one-off projects, you simply solve problems as they come up. Companies scale that effort by creating processes and following best practices in the formation of open source program offices. What if that company creates or participates in hundreds of projects every year? Do the practices scale, and how flexible can they be in following best practices while also maintaining coherence with legal, IP, and corporate policies?

The TODO Group's charter is to track program office best practices and share them with others. This presentation describes how Intel approaches this problem on a large scale.

U-Boot - Bootloader for IoT Platform? - Alexey Brodkin, Synopsys
Typical IoT devices have a limited amount of memory: both ROM and RAM sizes are usually measured in kilobytes as opposed to megabytes on Linux boxes.

This presentation demonstrates how to squeeze U-Boot with required functionality into a board with 256kB or less of ROM and RAM.
We'll start from an overview of U-Boot features that could be useful on IoT device and then we'll see what could be done to reduce U-Boot memory footprint with existing configuration options, which changes to generic or platform code might be done to shave off more extra space and finally how can we keep all the code in ROM preserving precious RAM for a payload.

Linux-based RTOS Experimental Platform for Constructing Self-driving Vehicles - Jim Huang, BiiLabs & Shao-Hua Wang, National Cheng Kung University
A holistic design and cost-efficient platform to construct self-driving systems is presented, with an emphasis on Linux-based software architectures for computer vision, control system, and inter-vehicle communication. The software is facilitated through the integration of ROS/OpenCV as well as closed-loop control algorithms and Linux in the run-time system. We built a rapid prototyping based on fundamentally open source technologies and hardware under $100, which allows developers to be explored and evaluated in realistic conditions efficiently. Using lane departure and the corresponding performance speedup, we show that our platform reduces the design time, while improving the verification efforts, with the aid of tweaked real-time executives.

Introduction to Natural Language Processing with Python - Barbara Fusinska, Google
Natural Language Processing techniques allow addressing tasks like text classification and information extraction and content generation. They can give the perception of machines being able to understand humans and respond more naturally.

In this session, Barbara will introduce basic concepts of natural language processing. Using Python and its machine learning libraries the attendees will go through the process of building the bag of words representation and using it for text classification. It can be then used to recognise the sentiment, category or the authorship of the document.

The goal of this tutorial is to build the intuition on the simple natural language processing task. After this session, the audience will know basics of the text representation, learn how to develop the classification model and use it in real-world applications.

10 Years of the Industrial I/O Kernel Subsystem - Jonathan Cameron, Huawei
This talk, by the original author and continuing maintainer of the Linux kernel IIO subystem looks at the path to where we are today, mistakes made, lessons learned and potential future directions.

A brief introduction will get the audience up to speed with IIO, in particular defining what IIO isn't! This will be use case driven; both common and the obscure / interesting.

This is not a tutorial, but rather a call to arms to drive things forward. It will include examples, but focus on the wider generalities rather than a deep dive. Diversions include taking a subsystem through staging; difficulty of defining userspace ABI; userspace drivers vs kernel drivers; mentor-ship both received and passed on; and the importance of community building and attracting new contributors!

No detailed knowledge of the kernel is necessary, just an interest in improving Linux support of sensors.

Extending the Performance Analyis Toolset - Christoph Sterz, KDAB
Finding and analyzing performance issues on embedded devices can be a tiresome search. Nowadays, modern sampling and tracing technologies are built into the Linux kernel to address this, in the form of perf and LTTng respectively. Still, the vast amounts of data recorded are difficult to handle on the limited embedded devices themselves. In the talk, I present Hotspot, an open-source performance analysis tool based on perf that enables you to visualize the recorded information and lets you navigate through the enormous amounts of sampled data offline. For tracing, sophisticated analysis tools such as TraceCompass already exist, but trace points in embedded userspace applications are rare. We see how LTTng tracepoints can be added to userland UI frameworks on the example of Qt. Here, I explain LTTng's low overhead and outline our plans in instrumenting Qt for the LTTng tracing ecosystem.

Uh-oh, It's I/O Ordering! - Will Deacon, Arm
The Linux kernel provides a rich collection of memory barriers which can be used to enforce ordering of memory accesses between multiple agents. In the case where these agents are all CPUs, we have recently adopted a formal model which allows developers to reason about concurrent interactions between them. However, when I/O and DMA-capable devices are added to the mix, the semantics once again being blurred and recent discussions on the mailing lists show a common lack of understanding of the intended barrier semantics.

This presentation will give a brief tour of the I/O ordering barriers support in mainline Linux: which barriers to use in your driver, when you need to use them and how to achieve the best performance.

Resilient and Fast Persistent Container Storage Leveraging Linux’s Storage Functionalities - Philipp Reisner, LINBIT
The Linux kernel has a large set of very powerful storage functionalities such as LVM, thin provisioning, RAID, SSD as HDD caches, deduplication, targets/initiators, and DRBD. They are all compatible on the data plane, but each brings its own control mechanism.

We can make use of all of these tools to build and manage block storage volumes (replicated either synchronously or asynchronously) as part of a larger storage cluster.

With the use of a management layer which integrates with OpenStack Cinder and Kubernetes FlexVolume (and potentially the new Container Storage Interface standard), we can provide a fully open source stack which provides persistent storage to containers.

This approach can be really powerful for IO-intensive workloads such as databases and works well both on hyper-converged infrastructure or on dedicated storage nodes.

Take any container running in your Kubernetes cluster. What can you say about it and with what level of certainty? Do you know where it came from? Could an attacker have modified it? Is it up-to-date? Can you identify the exact revision of the code that the image was built from?

This talk will look at what guarantees Kubernetes gives you out-of-the-box, and what you can do to establish a trustworthy and reliable workflow for deploying and updating images. Topics and tooling covered will include:

- mutable vs immutable images
- building images in a repeatable manner
- distributing images through registries
- verifying provenance with secure hashes as well as Notary/TUF

Diary of a Drive by Coder: Tips and Tricks for Working with Upstream - James Bottomley, IBM
Most of the community talks emphasize how to join the community and become an ongoing part of it, but what if you simply want to get a feature upstream and then move on to the next task? This behavior is called "Drive by Coding" and can be seriously frowned on by some communities who value ongoing community participation, but at the same time, it's the essence of the open source "scratch your own itch" principle.

This talk will showcase the experiences of an experienced kernel developer trying to do ecosystem enabling for kernel features via what is effectively driven by coding in the projects that should consume the feature. We will start off by talking about our first Drive-By coding experience: trying to get support in PulseAudio for using the UE Boom 2 Stick as a highly efficient conference phone and move on to our later work on TPM enabling the cryptography and key handling (ssh and gnupg) infrastructure in Linux. This talk will show a range of community behaviors varying from hostile to extremely welcoming, and detail the successes and sometimes spectacular failures. We'll derive lessons learned including how to smooth the path, how to get upstream to like you but also how to recognize when community hostility is intractable and what to do in this case.

Open Source and Open Community at a 100-year-old Company - Donnie Berkholz, Carlson Wagonlit Travel
Over the past 3 years, CWT flipped an 18,000-person enterprise upside-down, turning a travel company with some apps into a software vendor focused on travel. A brand-new product group brought together technologists across the company and around the globe for the first time.

18 months in, I joined to lead the DevOps transformation, aiming to speed time to value, improve customer experience, and increase collaboration. As part of that effort, needs quickly surfaced around areas like:
  • accelerating development through open-source adoption,
  • improving recruitment with open-source contribution, and
  • incorporating inner-source approaches to increase quality and speed.
To make those shifts, we drove adoption of a series of new tools — especially around source code and chat. Additionally, I was able to piggy-back onto existing efforts to define an open-source policy, apply a product-centric mindset, and expand that perspective into a cross-functional open-source program office.

This talk will describe our journey toward open at CWT, how we determined priorities and solutions, how we built bridges and overcame hurdles, and ultimately how we skipped entire generations in moving toward a modern view of open source in the enterprise.

Open Source Contribution Policies that Don't Suck - Tobie Langel, Codespeaks LLC
Open source contribution policies are long, boring, overlooked documents, that generally suck. They're designed to protect the company at all costs. But in the process, end up hurting engineering productivity, and morale. Sometimes they even unknowingly put corporate IP at risk.

But that's not inevitable.

It's possible to write open source contribution policies that make engineers lives easier, boost morale and productivity, reduce attrition, and attract new talent. And it's possible to do so while reducing the company's IP risk, not increasing it.

In this talk, we'll look at the general structure of contribution policies, examples in the wild, and tactics to make them suck less.

We'll also look at how to turn these policies into self-service software, preventing the tedious email back and forth between engineering and legal in most cases and making open source contribution a breeze.

A Zephyr User Story - Franco Saworski, blik GmbH
The choice for an RTOS can be an opaque one. There are a number of RTOS' available with different levels of feature sets, abstractions and out-of-the-box board support, which make the choice from a blank slate a very diverse one.

Franco will guide you through the decision process for an RTOS and goes on to discuss implementation details. The choice is driven by factors from a startup environment, including a small development team, industry standards and testing. Explicit technical touchpoints are board support, the lowpower subsystem, the memory and filesystem subsystems, and the networking subsystem.

Franco presents this from his three-year experience with Zephyr in the role as lead developer for industrial IoT systems in two startups. He has gained his knowledge over time from porting a bare-metal application to the RTOS, and upgrading the project to a new release version.

Building Real-Time Applications for Linux - John Ogness, Linutronix GmbH (Additional Track Registration Required)
Important Note: This session is only open to the 50 people who have registered for the E-ALE track, at an additional $100.00 fee.

When building real-time applications, it is critical that latency is controlled. On a general purpose operating system such as Linux, there are many things happening "under the hood" that can dramatically affect latencies within applications. However, Linux does provide interfaces to control and monitor the latencies of an application. In this session, John Ogness will cover the various sources of latency, show which APIs a real-time developer can (and should!) use to avoid them, and present mechanisms to verify the controlled latencies of an application.

Machine Learning for CI - Matthew Treinish & Andrea Frittoli, IBM
As more applications move to a DevOps model with CI/CD pipelines, the testing required for this development model to work inevitably generates lots of data. There are valuable insights hidden in this data that ML can help extract with minimal human intervention. Using open source tools like TensorFlow and Pandas we trained ML algorithms with real-life data from the OpenStack community's CI system. We built a Kubernetes application that sets up a prediction pipeline to automate the analysis of CI jobs in near real time. It uses the trained model to classify new inputs and predict insights like test results or hosting cloud provider. In this talk, we present our experience training different ML models with the large dataset from OpenStack's CI and how this can be leveraged for automated failure identification and analysis. We also discuss how these techniques can be used with any CI system

Collaborate on Linux for Use in Safety-Critical Systems? - Lukas Bulwahn, BMW Car IT GmbH
There is a current industry trend to build fully autonomous systems. To reach this goal, industry must manage complex software systems with high performance, safety and security requirements.
The operating system is non-differentiating in these systems and it is intended to be used multiple times over the whole product portfolio for a long time span. These conditions make it appealing to use Linux as robust open-source operating system.

OSADL's SIL2LinuxMP project has done initial investigations to use Linux in safety-critical systems, and provides first results to the public. Its further success however depends on enlarging the development partnership to provide an attractive solution to the overall industry. The talk shall sketch goals of a collaboration, development and business models of a collaboration and call interested companies to participate in this new collaborative project.

Complex Cameras on Linux - Mauro Carvalho Chehab, Samsung
The media subsystem supports two types of camera devices:
  • "traditional" media hardware, supported via standard V4L2 API, via device nodes, called devnode-based drivers. On those hardware, image processing happens at the camera. Those are meant to be used by customer-based devices.
  • Media-controller based devices, supported by 3 sets of APIs: Media Controller, V4L2, and V4L2 subdevices. Those are meant to be used by SoC-based embedded devices. On those devices, image processing happens at the SoC.
  • Devnode-based drivers are supported by "standard" media applications, but right now, media-controller based devices require a special design application.
Along with this speech, we'll cover both types of camera hardware and describe a recent effort of making both compatible with standard camera applications.

PREEMPT_RT isn't Just for Lasers: The Perfect Match for Hearing Aid Research! - Christopher Obbard & Daniel James, 64 Studio Ltd
Have you ever wondered how digital hearing aids are developed? Most people have probably never given this complex problem a second thought.

The Linux kernel (with the PREEMPT_RT patchset), GNU tools and Debian are the key ingredients for a project by the Cluster of Excellence group Hearing4all to research the development of new hearing aid algorithms.

The open Master Hearing Aid (openMHA) is an open-souce cross-platform toolbox which allows a user to form hearing aid processing chains. The software is scriptable to allow researchers to update and test algorithms on-the-fly.

At this session we'll present openMHA running on Mahalia, a mobile research platform composed of a BeagleBone Black Wireless, custom 6-channel soundcard (Cape4all) and battery. You'll learn how 64 Studio tuned the system to process all 6 channels of audio through complicated algorithms in less than 4ms!

From Handcraft to Unikraft: Simpler Unikernelization of Your Application - Florian Schmidt, NEC Labs Europe
Unikernels have produced impressive performance, including fast instantiation times, tiny memory footprints, and high consolidation, plus potentially a reduced attack surface and easier certification. Their main drawback is that they require applications to be manually ported to the underlying minimal OS; this means both expert work and considerable amount of time.

In this talk we present Unikraft, an incubator project under the auspices of the Xen Project and the Linux Foundation aimed at automating the process of building customized images tailored to specific applications and thus significantly reducing development time. Unikraft decomposes the OS into elementary pieces (e.g., schedulers, memory allocators, drivers, etc.) that users can pick and choose from. It then builds images tailored to the needs of specific applications as well as the target platform (e.g., KVM, Xen) and architecture (e.g., ARM or x86).

oomd: A Userspace OOM Killer - Daniel Xu, Facebook
Running out of memory on a host is a particularly nasty scenario. In the Linux kernel, if memory is being overcommitted, it results in the kernel out-of-memory (OOM) killer kicking in. In this talk, Daniel Xu will cover why the Linux kernel OOM killer is surprisingly ineffective and how oomd, a newly opensourced userspace OOM killer, does a more effective and reliable job. Not only does the switch from kernel space to userspace result a more flexible solution, but it also directly translates to better resource utilization. His talk will also do a deep dive into the Linux kernel changes and improvements necessary for oomd to operate.

Open Source Software Compliance - Supriya Chitale, Siemens AG
Open source software is being widely used in the industry across the globe. It has tremendous benefits and provides power to the developers. However, to quote a line from the movie, Spiderman: "With great power, comes great responsibility."

Unfortunately, very few users of OSS are aware of the compliance responsibility and fail to fulfill the obligations associated with OSS licenses. There are two reasons - lack of awareness and lack of accountability.

Supriya Chitale will shed some light on the pitfalls of using OSS without proper compliance. She will also discuss the general deterrence for OSS compliance among developers, how it can be overcome, and the best practices adopted at Siemens.

Software Philanthropy for Everyone - Kevin P. Fleming, Bloomberg
All large companies use open source software. Many of them contribute to open source software.

In addition to that many large companies have philanthropic arms; charitable foundations operated by the company or aligned with the company, and primarily funded by the company. These foundations have focus areas which include many charitable causes, but not open source software!

This presentation will talk about Bloomberg's journey to add software philanthropy to its charitable contributions, including the mundane aspects of volunteer coding events, soliciting mentors/leaders, organizing participation, and others, but also how this type of philanthropy can be included in 'employee giving'. Anyone who runs an Open Source Program Office, or similar group, in a company that also has a philanthropic arm should include open source software contributions in their plans.

Did you know that open source is a critical piece of the solution to ending global poverty? Why just simply scratch an itch when you can end poverty one line of code at a time. The World Bank has a target of ending Extreme Poverty (people living on less than $1.90 per day) by 2030 - while they just announced that global poverty is at its lowest rate in history, we are not on target to achieve that goal.

A new approach is needed, an open one. The Mifos Initiative has been refining our completely open fintech approach for the past decade. While it starts with technology - truly open source core banking infrastructure - it doesn’t stop there. It’s guided by a global open source community, sustained and supported by open source business models, and fueled by open standards and open knowledge sharing. We’ll walk you through the evolution of our core banking stack, show you the innovations our ecosystem has pioneered, demonstrate its incredible impact in reaching 10 million individuals globally, and help you discover how you can join us in fighting poverty with financial inclusion

Mentorship Panel: An Exploration of Insights & Issues Related to Mentoring Programs - Moderated by Jeffrey Osier-Mixon, Intel
OSS is fuelled by the continual influx of new contributors who offer fresh talent and diverse perspectives. Mentoring programs and activities, like GSoC, Outreachy, and Speed Mentoring, are critical in inspiring this next generation of contributors. Having these newcomers as productive as possible in a short period of time is key to produce successful outcomes for the project.

However, it brings challenges. Onboarding guidelines, CoC, clear development guidelines, and other documents are required to establish and maintain environments that encourage participation from new contributors.

This panel aims to explore the process through which contributors enter the Linux or the OpenStack community through some of these initiatives, such as Outreachy and GSoC, tracks their activity as members within these programs, and will show data and charts related to the retention once their participation in these programs ends.

OpenOCD - Beyond Simple Software Debugging - Oleksij Rempel, Pengutronix
OpenOCD has many use cases. Many people use it to debrick home routers, some developers use it to debug firmware for microcontrollers. The fearless debug Linux kernel code with it. I use it to reverse engineer closed or not completely open parts of firmware on some hardware, just for fun. This is an important swiss knife tool for many embedded developers and hackers.
What else can we do with OpenOCD? In this talk, I will go through other, not so common use cases of OpenOCD:
- Use Boundary Scan not only to test proper soldering but also test software configuration.
- Use it for hardware troubleshooting.
- Use it in combination with IDA Pro for reverse engineering or debugging. Or maybe use radare2 to do that?

This talk should provide you with some ideas and inspiration.

Real-time Testing with Fuego - Hirotaka MOTAI, Mitsubishi Electric Corp
Current Linux can be adapted to various embedded devices even though they need hard real-time response. But ensuring adequate performance is always necessary for releasing products. That is the reason why we are focusing on auto-tests that also inspect real-time performance.

In ELC 2016 we presented how to customize “Fuego” for testing various embedded devices. And now we have developed a new test set called “cyclictest+ff (ftrace features)” in Fuego. cyclictest+ff can be used not only for testing real-time performance but also determining, from the result logs, what caused the response delays.

In this presentation, we will share details of cyclictest+ff, along with descriptions of our actual use cases.

The End of Time, 19 Years to Go - Arnd Bergmann, Linaro Ltd
Software that uses a 32-bit integer to represent seconds since the Unix epoch of Jan 1 1970 is affected by that variable overflowing on Jan 19 2038, often in a catastrophic way. Aside from most 32-bit binaries that use timestamps, this includes file systems (e.g. ext3 or xfs), file formats (e.g. cpio, utmp, core dumps), network protocols (e.g. nfs) and even hardware (e.g. real-time clocks or SCSI adapters).

Work has been going on to avoid that overflow in the Linux kernel, with hundreds of patches reworking drivers, file systems and the user space interfaces including over 50 affected system calls.

With much of this activity getting done during 2018, it's time to give an update on what has been achieved in the kernel, what parts still remain to be solved, and how we will proceed to solve this in user space, and how to use the work in long-living product deployments.

Beyond the DSL—Unlocking the Power of Kafka Streams with the Processor API - Antony Stubbs, Confluent Inc.
Kafka Streams is a flexible and powerful framework. The Domain Specific Language (DSL) is an obvious place from which to start, but not all requirements fit the DSL model.

Many people are unaware of the Processor API (PAPI) - or are intimidated by it because of sinks, sources, edges and stores - oh my! But most of the power of the PAPI can be leveraged, simply through the DSL `#process` method, which lets you attach the general building block `Processor` interface to your -easy to use- DSL topology, to combine the best of both worlds.

This talk will look at the flexibility of the DSL’s process method and the possibilities it opens up. We’ll use real world use-cases borne from extensive experience from users to explore power of direct write access to the state stores and performing range sub-selects. The options that punctuators bring to the table, as well as opportunities for major latency optimisations.

L1TF and KVM - Alexander Graf, SUSE
Recently a new speculative execution side channel was unvealed, which
could potentially result in leakage of arbitrary memory contents into
unprivileged virtual machines on most recent Intel CPUs. This
presentation will give insights as to what the L1 Terminal Fault (L1TF)
Spectre vulnerability is. It will show how it can be exploited and based
on that knowledge it will take a look at how KVM mitigates those
issues. It will also show performance penalties these mitigations incur.

On top of that, the presentation will present an alternative work in
progress approach to mitigate L1TF that may recover some of the
performance penalties by leveraging unrelated CPU features.

Building OCI Images without Privilege - Tycho Andersen, Cisco Systems
An age old problem, especially in large enterprises, are piqued sysadmins who rightfully do not trust developers and won't give them root. Another age old problem of containers is: how do we build root filesystems to run? A smooth experience for building rootfses is one of the things that Docker made a great experience, but it uses a privileged daemon. And yet, the developers have to build product binaries on systems that are provided by said sysadmins.

Enter stacker, a tool which can build OCI images without privilege, using user namespaces via LXC, without any extra trickery. In this talk Tycho will give a brief introduction to stacker's declarative yaml format for building container images. He will also give a basic overview of the guts of stacker and how it accomplishes its goals.

Backporting is so 1993 - Ricardo Salveti & Michael Scott, Foundries.io
We have seen no slow-down of critical vulnerabilities in computing systems, luckily successful open source projects can protect us, right? Oh but wait, what if you rely on long-term-support (LTS) software that hasn’t been updated yet, or your engineers created a customized franken-kernel to support a specific product? How can you wait for LTS to be updated or hire key experts to cleanly backport critical fixes? And how do we get this to our hundreds, thousands or millions of deployed products quickly?

Instead of continuing the trend of forking and backporting, it's time to work with the community on the latest software where the developers are addressing bugs, security issues and improving performance of their projects. Ricardo and Mike will show you how you can build better embedded products with the help of some amazing new open source technologies and some good design practices.

How Having Kids from Hard Places Helped Me Serve Open Source Communities - John Mertic, The Linux Foundation
Trauma is real. 70% of adults in the U.S. have experienced some type of traumatic event at least once in their lives. PTSD is recognized as a psychobiological mental disorder than can affect survivors of combat experience, terrorist attacks, natural disasters, serious accidents, and silently life events like assault or abuse, or even sudden and major emotional losses.

Raising children with this background gives you a unique perspective on human behavior that often is considered "problematic" or "distractive", which taught me to look beyond the visible actions. In this talk, I'll share some of what I've learned, how this has changed how I react to others, and tips for recognizing trauma in your project and how to ensure those individuals can be effective participants.

On this Rock I will Build my System - Why Open-Source Firmware Matters - Lucas Stach, Pengutronix
Modern embedded systems are getting ever more capable and in turn more complex. Part of this complexity is shifted away from higher layers like the Linux kernel to system software running before the operating system is started and in many cases remaining active during runtime. There are good reasons to move some of the functionality into those layers of software stack, but it also means that the kernel has less control over the system than it traditionally had in an embedded system.

This talk will outline some of the functionally that is moving away from the OS, the risks associated with not being in control of those functions and how open-source system software/firmware is a strong base to minimize those risks and helps in designing a solid system.

Real Time is Coming to Linux; What Does that Mean to You? - Steven Rostedt, VMware
The Real Time patch (what makes Linux into a true Real Time operating system) has been developed out of the kernel since 2004. 14 years later, there is a real effort to finally make it into the mainline kernel, within the next year. All the major road blocks that have kept it from being merged have now been solved. But once it is in mainline, all kernel developers will now be responsible for not breaking it. Being real-time friendly is not hard, and in fact, it forces you to write cleaner and more maintainable code. This talk will focus on what kernel developers will need to understand about PREEMPT_RT, whether they are writing core kernel code, or some fringe kernel driver. Even if you do not care about PREEMPT_RT, come and learn about some programming tips for keeping your code maintainable.

Effective Virtual CPU Configuration with QEMU and libvirt - Kashyap Chamarthy, Red Hat
QEMU (the open source machine emulator and virtualizer) and the libvirt API allow a variety of ways in which CPUs can be configured for virtual machines (VMs). In light of the recent CPU hardware flaws, it is becoming increasingly difficult to choose an effective CPU configuration.

In this presentation, we will walk through the distinct CPU configuration interfaces QEMU offers, and in turn, how the libvirt project uses those interfaces to provide convenient APIs for higher-level applications. We will also consider critical needs such as the ability to live migrate a VM across hosts with a diverse set of CPUs; or the flexibility to add or remove specific CPU features from a guest CPU model, to mitigate various hardware CPU flaws.

The talk will be set in context such that developers and users of higher-level management software (e.g. OpenStack Nova) will, hopefully, gain an appreciation for the details.

To Kill, or to Checkpoint - That is the Question - Mike Rapoport, IBM & Adrian Reber, Red Hat
Cloud native containerized applications heavily rely on resiliency. When a container dies, it is restarted. When a node is under evacuation, containers it hosts are killed and started
elsewhere. But there are occasions when checkpointing and restoring a container would be more effective. Long-running jobs, stateful applications, function runtimes for serverless computing, all could benefit from checkpoint-restore and container migration. And for some applications, the absence of these capabilities could be a show stopper for moving from virtual machines to containers.

With CRIU, the industry standard container migration tool, it is possible to migrate containers and reboot hosts without losing network connections, results of long-running calculations, or the state of
in-memory databases.

In this talk, we present the container migration technology and its applicability to various use cases.

Security in QEMU: How Virtual Machines Provide Isolation - Stefan Hajnoczi, Red Hat
Is it safe to use QEMU to do X? This talk explains the security model and use cases that QEMU is designed for.  Understanding the security model is critical for deploying virtual machines as well as contributing code to QEMU. This talk gives an overview of the attack surfaces, including emulated devices, the monitor, remote desktop, disk images, and the CPU accelerators.  Virtual machines offer isolation from each other and the host if QEMU is configured properly. Most of these best practices are encapsulated in libvirt, but not all users choose to use it, so it is worth understanding them. Finally, no discussion of security in QEMU would be complete without reviewing CVEs and the lessons learnt from them.

What are My Microservices Doing? - Juraci Paixão Kröhling, Red Hat
Microservices have become the standard for new architectures. But the microservices architecture presents some new challenges. One of them is the so-called “Observability problem”, where it is hard to know which services exist, how they interrelate, and how important each one is. In this talk, we’ll look at an application that includes three Java microservices. We’ll use OpenTracing and Jaeger to help identify what they are doing and how they interrelate, following a “no instrumentation” approach, a “full instrumentation” approach, as well as “something in between” using service mesh instrumentation with Istio.

OpenSource @ Improbable - Dominic Green, Improbable
OpenSource projects are not only maintained in the free time of passionate engineers but also by talented engineers as part of their companies software development lifecycle.

This talk will look at Improbables approach to OSS projects; from deciding what and how we open source projects but
also how we as a company support the community after release.

We will discuss how OSS not only a benefit the community but help Improbable as a company grow, be innovative and attract talent.

Improbable currently has a number of OpenSource projects ranging from our core SDKs to Thanos our metrics platform built on top of Prometheus and various Go middleware projects, with a few more in the pipeline to be released in the near future.

The Democratization of Software - Stephen Walli, Microsoft
In 1995 everything changed with the creation of the World Wide Web. Anything that could be digitized was digitized and entire industries changed. And with the digitization came tools to help everyone become a producer of digital content. From music to video, books to journalism, we pulled all the friction out of the content pipeline and democratized entire industries.

But the industry we never talk about is the one that was already digital – software. Software was democratized as well. We’ve shared software for as long as we’ve written software. By pulling the friction out of the pipeline around software and sharing it liberally through open source licensing, we’ve ended up in a completely new software industry over the past 20 years.

This talk presents the trends that got the industry to where it is, as well as ideas for the coming challenges for the next twenty years of open source software. It might be a cautionary tale.

Blockchain won't Kill the Database Function: A Developer's Perspective - Colin Charles, GrokOpen
The blockchain is definitely exciting and a lot of database people tend to say you can get away with a database and replication. However, the blockchain definitely has uses that are suited to it, while for many instances maybe a regular database is better. Find out when to use a blockchain or a replicated database, amongst other things in this talk.

Some topics covered:
- blockchains compared to traditional databases
- centralisation and decentralisation (as well as the idea of private versus public blockchains)
- transaction speeds
- the different implementations of blockchains
- protocols and interoperability
- combining the blockchain with a database
- databases on the blockchain for some applications
- when to actually use a blockchain
- when a CRUD database is better
- when do decentralised databases make sense for distributed applications (dApps)?

Creating Your Own Tiny Linux Distribution Using Yocto: Keeping it Small With Poky-Tiny - Alejandro Hernandez, Xilinx
Poky-tiny was created in 2011, it is a reference distro provided by the Yocto project that is meant for resource-constrained embedded devices.

It provides a “fully” running Linux OS, with the most basic functionality, by using software like busybox, musl, and dropbear to provide common UNIX utilities, a lightweight, yet compatible and efficient C library and a Secure Shell (ssh) server-client respectively.

In this presentation, Alejandro will talk about the latest changes that have been made to poky-tiny, explaining concepts such as a DISTRO layer to present how it is built and how users can easily customize it to create their own Tiny Linux, he will also go through the process of how the distribution is kept small, analyze the size of the kernel and rootfs and a new image core-image-tiny-initramfs that boots to RAM for faster boot time, comparing that to other images as an example.

Kernel Analysis Using eBPF - Daniel Thompson, Linaro
The extensions in eBPF, the extended Berkley Packet Filter, transformed BPF into a powerful in-kernel virtual machine and ultimately allowed eBPF programs to be attached to many parts of the kernel, many of which have nothing to do with network packets!

In this session Daniel will review the low-level mechanisms that allow developers to gather information for debug and tuning by attaching eBPF programs to probe and tracepoints. Daniel will follow up by dissecting a roll-your-own example program to illustrate how userspace exploits these mechanisms.

After that we move from theory to practice by looking at several userspace tools that allow developers to write high level eBPF programs (or run other peoples pre-canned ones) and process the resulting data.

Sound Open Firmware - Liam Girdwood, Intel
Sound Open Firmware is an open source audio DSP processing firmware started by Liam Girdwood at Intel that would like to be the "Linux" of audio DSP firmware.

This presentation tells the story how a one man skunk works project for Minnowboard turned into a multi product and multi vendor opensource project alongside the technical features that can give users the edge over traditional audio.

Liam will also share details and insights gained on taking traditionally closed firmware and hardware into the opensource world and how this could be applied to help create open source firmware for other subsystems.

The SDK will be introduced that can be containerized and use either opensource tools, proprietary tools or a mixture of both for compilation, debug, tracing, code signing and heterogeneous virtualization of both driver and firmware.

Fine-grained Distributed Application Monitoring Using LTTng - Jérémie Galarneau, EfficiOS
There is no shortage of great tools to monitor distributed applications. However, most of them focus on monitoring overall performance metrics and error rates, giving only a general idea of the health of an infrastructure.

Unfortunately, rarely occurring issues are often hidden by general trends making it difficult to completely understand infrequent, yet sometimes catastrophic, problems.

Tracers are great at tracking down sporadic problems in production environments, but the amount of data they generate can be hard to manage in the wild.

This talk will present how the work done on LTTng over the last year, notably the introduction of a session rotation mode, makes it easier to integrate fine-grained monitoring in production environments.

The talk will also cover approaches to collecting traces on multiple hosts to troubleshoot problems occurring in distributed systems using both kernel and user-space traces.
