Using Tracing at Facebook Scale, Yannick Brosseau, Facebook
Facebook systems are complex and are stressing the Linux kernel in various, extreme, ways. As we move to kernels that are closer to mainline, we need tools to help us improve the kernel stability and performance. This presentation will describe how we use the various Linux tracing tools for debugging and continuous performance monitoring. We will also cover the road blocks that we faced and what improvements would be a benefit to us.

User Case Study: Tracing in the QEMU Emulator - Stefan Hajnoczi, Red Hat
The QEMU machine emulator is used by projects including KVM, Xen, and Linaro to emulate hardware. Low overhead instrumentation is important both for developers and in production. This talk covers how tracing is used in QEMU. QEMU abstracts tracers using a code-generation tool called 'tracetool'. This allows the cross-platform codebase to work with DTrace, SystemTap, LTTng UST, and others. Although tracetool is part of the QEMU source tree, it could also be reused by other projects. Users often wish to get started without installing a tracer, so QEMU provides a built-in tracer called 'simpletrace'. Although it's features are modest, it offers a Python module for writing custom analysis scripts. This makes it a powerful tracer during development. Tracing has been integrated into the very core of QEMU. Recent patches make it possible to trace just-in-time compiled code.

From Network to Application: Understanding Your Distributed System with Trace Compass - Geneviève Bastien, École Polytechnique de Montréal; Bernd Hufmann, Ericsson

Trace Compass (previously TMF) is an extensible framework for building trace analysis and visualization tools. With the built-in CTF and Pcap parsers we will demonstrate analyses of data at network, hypervisor, operating system and application level using a simple distributed application. You will see:

  • Network traffic analysis: Correlate network traces (Pcap) with application traces,
  • Data driven analysis: Analyze and visualize recorded data in custom views without writing of a single line of Java code,
  • Virtual machine analysis: If the applications is in a virtualized environment, the host and VM's traces can be correlated and show the resource usage (CPU, VCPU). We can observe a totally different execution than the one from 2 different machines. and explain latencies in the application's execution.

What's CGManager Doing and Why is it Still Relevant - Serge Hallyn, Canonical
The cgroup manager (cgmanager) is an effort by the LXC project to
address a specific set of goal: support unprivileged nesting and
nesting to multiple levels; allow userspace in containers to
administer their delegated cgroups the same way as on the host; and
simplify the cgroup code in lxc itself.

We will describe the requirements, design, and API. We will go over
the specific security guarantees and show how cgmanager provides these
guarantees for each API method. Finally we will discuss - and hopefully
receive input on - the relation of cgmanager to other parts of the linux
ecosystem including libcontainer, criu, and systemd, and discuss next steps.

Mixing Your Open Source Cloud Cocktail - Mark Hinkle, Citrix
Add two parts virtualization, one part orchestration add a little networking shake and pour. Unfortunately cloud computing isn’t that easy but then again not all clouds are the same and tastes may vary. This talk will discuss how the varying open source technologies like OpenStack, Docker, LXC and others can be mixed together to make something that appeals to the needs of a wide variety of users. There’s also no problem in abstaining from building your own cloud but still benefiting from the open source tooling to maximize the benefits of the public cloud.

What Manufacturing Teaches About DevOps - Gordon Haff, Red Hat
Software development, like manufacturing, is a craft that requires the application of creative approaches to solve problems given a wide range of constraints. However, while engineering design may be craftwork, the production of most designed objects relies on a standardized and automated manufacturing process. By contrast, much of moving an application from prototype to production and, indeed, maintaining the application through its lifecycle has often remained craftwork. In this session, Gordon Haff discusses the many lessons and processes that DevOps can learn from manufacturing and the assembly line-like tools, such as Platform-as-a-Service, that provide the necessary abstraction and automation to make industrialized DevOps possible.

The Orc Quest for Better Embedded Multimedia Performance Adding MIPS support to liborc. - Guillaume Emont, Igalia
Modern CPUs to include SIMD instructions which are particularly suitable for processing multimedia, and this is a trend that is arriving to the embedded designs as well. Even when some platforms may provide dedicated dedicated hardware for audio and video processing, it may still be necessary to make a good use of the main system processor for other kinds of data processing. Not to mention that optimized software also uses less battery, which is a main concern for portable embedded devices.

We implemented a MIPS back-end for liborc, a library which provides an architecture-independent API to process data streams, generating machine code via JIT optimized for the task and processor at hand. The target platform was the modern MIPS 74kf cores, which include new SIMD instructions. With the MIPS Orc backend in providing performance improvements of 5 to 10% to various GStreamer components.

Enhancing Real-Time Capabilities with the PRU - Ron Birkett, Texas Instruments
Love Linux. Need hard Real-time? Seems like these might not go together, but with the PRU (Programmable Real-time Unit) and a Cortex-A running Linux, you might be surprised. Especially since a lot of work has been done recently to add remoteproc and rpmsg support for the PRU. This allows the PRU to handle some cool hard real-time tasks and interact with Linux to provide the best of both worlds at a system level.

Is SSH Really Secure? - Peter Tornberg, Fox Technologies
SSH is nearly ubiquitous in today’s enterprises, and is the predominant tool for managing Linux servers and the applications and data that they host.  Poor practices around the deployment and management of the SSH infrastructure has been blamed or associated with various breaches, and has gained considerable attention from management and administrators. A number of reports over that last two years have exposed the vulnerabilities in SSH; not in the protocol or software itself, but in the poor practices deploying, managing and maintaining control over it.

SSH must be managed properly, in a way that accounts for its various methods of authentication, and in a way that accounts for its various features. But, even properly managing SSH alone does not actually ‘secure’ an SSH deployment.  SSH relies on accounts, and they must be accounted for in a security plan,  along with what people are allowed to do once they connect.

In this presentation, we will discuss the numerous pitfalls and common mistakes related to SSH deployment; as well as best practices in properly deploying SSH across your diverse server environment.

Evaluation of Real-time Performance in Embedded Linux - Hiraku Toyooka, Hitachi
Linux has already been used in real-time systems. Current mainline Linux supports a variety of real-time features such as deterministic scheduling, kernel preemption, high-resolution timer and IRQ thread. In addition, we can get more deterministic behavior by using PREEMPT_RT patch set. To benefit from those features, we need to pay attention to many kernel configurations, use of appropriate APIs and hardware settings. In this presentation, I will talk about how to enable those real-time features and how to evaluate real-time performance by tools such as rt-tests or by your own program. I will also show measurement results in some ARM Cortex-A boards.

LiMux And The FOSS Ecosystem - Stefan Koehler
The LiMux project has gained worldwide attention when the City Of Munich decided to switch to a linux­based client in 2003. Today more than 15.000 clients run on LiMux. This talk will shed light on the initial decision process, the projects history und current state. It will get you to know the technical base that secured the projects success and the infrastructure used for system and configuration management.

LiMux heavily relies on FOSS components like (K)Ubuntu, Puppet, LibreOffice or Firefox. The talk will highlight the requirements to use FOSS in an enterprise environment, how well these requirements were met and what developpers might bear in mind to make life easier for people actually using their software on a larger scale.

From the very beginning the LiMux projects has been under immense attack from various sides. Nevertheless it became a huge success and working on a linux­based client has become routine for the majority of Munich's employees. The talk will conclude by trying to draw a picture of the projects future and how LiMux and the community may interact closer to make both worlds better.

Non-Coders Wanted: How to Get and Keep Non-technical Volunteers - Deb Nicholson, OIN
Many distributions and projects sorely need writers for documentation, press releases and blogging or experts on outreach, fundraising and volunteer management or a friendly pack of translators, but aren't sure how to get them. Tweaking your volunteer pitch, looking in different places, being open to different communications channels, and finding ways to appreciate folks will help immensely.

Once you've got them, letting your new non-coding contributors get on with what they're good at will help them feel invested. In this talk, I'll discuss how to set parameters for non-coding tasks so that everyone is happy.

Tutorial: Hands On Trove: Database as a Service in OpenStack - Florian Haas, Hastexo
OpenStack, the fastest growing infrastructure-as-a-service (IaaS) platform in the open source community, has recently added a database-as-a-service (DBaaS) component named Trove, which saw its first production OpenStack release in April. Trove’s purpose is to provide scalable and reliable cloud DBaaS provisioning functionality for both relational and non-relational database engines.

In this presentation, we examine the motivation behind DBaaS, cover the architecture of Trove, and demonstrate the deployment of OpenStack Trove on an OpenStack private cloud, in order to provide MySQL DBaaS to OpenStack users. It is useful both for private cloud operators intending to deploy DBaaS, and to MySQL DBAs learning to interact with MySQL in an OpenStack DBaaS environment.

U-Boot for Tizen

Utilization of u-boot bootloader at Samsung's Linux powered platforms has a long history. For Tizen 3.0 the reference devices for mobile profile (RD_PQ and Odroid U3/X2) are due to run with u-boot developed with open source philosophy applied. It means that the code was developed, reviewed and tested first in the open source and then reused in Tizen.

Introduced changes to mainline code were minimal and only necessary for assuring backward compatibility. In his presentation Lukasz will briefly cover history and future plans of u-boot development for Tizen (as e.g. ongoing work on single binary for Odroid U3 and M0), explain key aspects of persuading community to accept solutions tunned for mobile devices, present remarkable u-boot's war stories and give a handful of tips for successful cooperation with community.

Discover What Your App is Waiting With Kernel Tracing - Francis Giraldeau, École Polytechnique de Montréal
System administrators and developers are challenged by understanding the elapsed time of heterogeneous and distributed programs in order to improve response time. Profilers are useful to identify hotspot code in an application, but they do not take the wait time into account. A task can block for a device, a local task using any inter-process communication or a task running on another computer. We present a technique using solely kernel tracing to recover the active path of a computation, crossing machines barrier. The technique uses scheduling, interrupt and network events, but does not require system call tracing nor user space instrumentation. Therefore, this technique works for any programming language, and includes interactions with kernel threads. We show the analysis result of actual use-cases, including shell scripts, RPC request, file server and web app.

Porting LTTng to Android for Kernel-Space and Native User-Space Tracing - Charles Briere, Samsung
Android already have some nice debugging and profiling tool, but when it comes to tracing, you mostly rely on Perf and Ftrace. From the nature of Android being mostly Java based, having LTTng on there would be greatly useful to aggregate kernel, native application and Java application traces. However, it doesn't come free as some features on standard Linux OS are not available on Android. Most important differences in this case are within IPC, base libraries and build tools.

U-Boot on Sunxi

Hans would like to start a discussion on how to get (more) manufacturers engaged in upstreaming their work / working directly with upstream from day one.

His own experience in this comes from the Allwinner sunxi support, where Allwinner themselves are shipping quite an old u-boot version, which is not even fully functional as it gets chainloaded by a custom loader which sets up RAM first. Thanks to the work of various people in the community we've a fully functional U-Boot (replacing the custom loader) for sun4i, sun5i and sun7i.

Beyond Golden Containers: Complementing Docker with Puppet - David Lutterkort, Puppet Labs
Docker offers an exciting new way to use containers for delivering and managing applications. Combining Docker with a configuration management system like Puppet provides much greater control over containers, both at buildtime and at runtime: at buildtime, Puppet's fine-grained resources such as file, cron, and user make it easy to control an image build in great detail; Puppet's facilities for weaving the description of a system together from different concerns make it easy to express similarities and differences between a fleet of container images concisely and understandably. At runtime, Puppet can be used to detect configuration drift and remediate such drift. When image building and deployment is performed by different parties, Puppet manifests also document the details of a container's setup and expose the knobs that can be used to control the payload of a container.

A Cloud Management Primer - John Mark Walker, Red Hat
What is "Cloud Management"? In a datacenter, you might have 2 or more virtualization management platforms, with a private cloud running alongside, and some workloads running in a public cloud.

Across all these, you want to be aware when there are problems, enforce some kind of consistency in who can consume your resources, and be aware of waste when it is happening. Maybe you also want to automate the provisioning of instances, integrate with a service catalog or configuration management system. Perhaps you want to know when VMs are vulnerable to security issues, prevent new VMs to be created from known-bad templates, and perform some clean-up of services when they are retired.

These are all cloud management problems. Whether it's curing VM sprawl or finding and fixing hot spots in the data center, this presentation will give you tools and techniques you can use to manage it all.

12 Lessons Learnt in Boot Time Reduction - Andrew Murray, Embedded Bits Limited
It's not uncommon to produce embedded Linux based devices that end up with long and inconvenient boot times - yet eliminating boot time delays can be difficult and time consuming. Furthermore once a minimal boot time has been achieved it's often just as difficult to maintain it through subsequent software development.

In this presentation, Andrew unfolds 12 keys lessons learnt in his experience of boot time reduction. These lessons provide an insight into the common causes of boot time delays, why they are present and how they can be overcome. In describing these lessons Andrew will also take you on a journey that indicates why file system benchmarks should probably be ignored (with respect to boot time reduction) and a journey that illustrates that the Linux kernel is rarely the worst offender for boot delays.

Case Study: Building a High Quality Video Pipeline Using GStreamer & V4Linux on an i.MX6 - Sean Hudson, Mentor Graphics
Building a low latency, high quality video pipeline in Linux requires the integration of several components that, in theory, should go together quickly and without much effort. Unfortunately, that is not always the case in the real world. In this talk, Sean Hudson will present a case study that outlines the work of building such a pipeline on an quad-core i.MX6 using V4L drivers and GStreamer plugins. During the talk, he will discuss the design decisions and tradeoffs made. He will discuss the impact that available hardware resources and sensor selection had on the project. Also, he will describe the tools used to identify areas for improvement. Throughout, he will highlight both the things that worked well and the things that didn't.

Overcoming Obstacles to Contributing to Linux - Tim Bird, Sony Mobile
Many companies struggle with contributing to Open Source projects. This talk will identify key difficulties that many large companies face in making contributions, and provide tips and lessons learned for overcoming these obstacles. Some of the difficulties discussed will be: version gap, expertise problems (an example of which is the "proxy problem"), wrongly-abstracted code, process mismatch, and social and attitudinal barriers. This will not be yet another talk on CodingStyle, but a more high-level look at structural problems inside companies and the industry that prevent meaningful engagement within the open source community.

The goal of this talk is to help individual developers and companies identify and implement practices that will accelerate their participation in open source, so that they can enjoy more of the value of open source besides just the open code base.

What Can Possibly Go Wrong? - Konrad Zapalowicz, Cybercom Poland
Although being fun to do and quite easy to start the Linux kernel development is considered hard, time consuming and it is said that it requires access to hardware. With this in mind many people might hesitate to try it out. In this presentation Konrad is going to use himself, a newbie contributor, as an example of how easy it is to start what did he learn (during the Eudyptula challenge and so far) and how this knowledge can be used to submit patches and participate in the upstream kernel development.

Runtime Analysis of Parallel Applications for Industrial Software Development - Daniel Becker, Siemens & Markus Geimer, Jülich Supercomputing Centre
Utilizing the parallelism offered by multicore CPUs is hard, though profiling and tracing are well-established techniques to understand, debug, engineer and optimize codes. While many tools are available to capture profiles and traces, these tools are often difficult to use in industrial contexts. Tool development often started with sequential applications in mind to transition to parallelism not until later, resulting in improper feature sets and usability. In contrast, parallel tools are often targeted towards HPC with a strong focus on MPI and OpenMP. As this turns these tools less suitable for codes using alternative threading models (POSIX, Qt, and ACE), this talk presents extensions to the open-source profiling and tracing tools Score-P and Scalasca. Score-P captures detailed program execution data allowing Scalasca to perform a sophisticated performance and wait-state analysis.

LXC and Why System Containers Matter Too - Stéphane Graber, Canonical Ltd.
There has been a lot of noise lately around application containers and how they make shipping your software much simpler by letting you bundle everything in a consistent way.

But there are cases where you just want a good old fully functional distro, those cases may include some random software having specific support requirements, or just offering shells or development/staging systems, ...

Now this can obviously be achieved through virtualization but running a Linux VM on a Linux host isn't the best use of your hardware, system containers are much lighter weight, faster and make things like sharing directories or physical resources trivial compared to VMs.


In this talk, I'll be presenting what LXC is capable of doing nowadays with system containers, some of the new management tools we've been working on and show just how easy it is to manage a whole network of those.

Open Source Medical Accessories - Philip Verbist, XsOnline & Rocky De Wiest, Belgian Defence
It all started with a seafarer fainting at full sea. He felt fine afterwards, but his heartrate had dropped to only 35 bpm. In this situation, the only thing a captain can do for the seafarer is to call a doctor and explain his problem over the phone or via email… If you’ve tried fixing a technical issue over the phone before, try this.

On the one hand, rescueing a seafarer from a ship mid-sea is very expensive, but not rescueing him might be even more expensive. On the other hand, the doctor at shore needs more information to be able to save the seafarer.
What if we could send a "stack trace" to the doctor?

In this presentation Rocky de Wiest and Philip Verbist will discuss the current (technical) state of their project regarding global medical advice, and look forward to the future of open source software in healthcare.

Transactional Device Tree & Overlays: Making Reconfigurable Hardware Work - Pantelis Antoniou, NVIDIA
Device tree has been decreed as the modern way to describe a board's hardware, but falls flat when faced with the problem of hardware that it-self is reconfigurable. While this is more prevalent on systems employing FPGAs, it is actually a problem for low-end boards like the Beaglebone & any other device that exhibits flexibility in configuration its interfaces. Limitation of in-kernel DT support make it hard to apply batches of changes and revert in need be.

The new Transaction Device Tree + Overlays patch-sets overcome these problems and are intended to land in mainline during the next few major revisions.

ARM formed the Linaro consortium in 2010, a non-profit organization composed now of over 20 industry leading companies. Linaro's aim is to provide an open source common software and tools foundation for the industry to use - making it easier and quicker to develop Linux-based products. In 2013 Linaro formed a “sub-group” called the Linaro Networking Group (LNG). LNG with twelve industry leading hardware and software vendors has since launched a new initiative called “Open Data Plane”, or ODP. ODP is an initiative designed to promote an open API specification, and an open source and cross platform implementation for high performance data plane packet processing that is independent of current solutions that require software or hardware vendor “lock-in”, like Intel's DPDK and Freescale's USDPAA, etc. This presentation is an overview of a) what ODP is, and b) the current status of ODP.

Tux On Top: Open Source at the Top of the Rack - John W. Linville, Red Hat
Enterprise packet switching hardware has continued to be a hold-out against open source in the data center. The reasons for this include many of the same, tired, old arguments used in earlier fights around open source. But, at least part of the issue has been that such devices have traditionally included an under-powered CPU complex where modern Linux was just not practical anyway.

For a variety of reasons, designs are appearing that couple modern packet switching hardware with CPUs comparable to those used in contemporary server machines. Couple that with efforts like the Open Compute Networking Project, and the possibilities for open source networking infrastructure in the datacenter starts to look like a real possibility.

How would such a box look? What would we do with it? What should we do to get it? These are the questions this talk intends to address.

Tutorial: Getting Started with Coccinelle - Julia Lawall, Inria
Coccinelle is a program matching and transformation tool for C programs that has been extensively applied to the Linux kernel and is used on a number of other C code bases. Coccinelle makes it easy to specify software specific rules for finding bugs and for updating software to use new APIs. These rules can then be applied automatically across an entire code base. Over 40 Coccinelle rules are already available in the Linux kernel source code. The goal of this tutorial is to enable developers to write their own. The tutorial is designed to be hands on. Participants should have Coccinelle (available via most Linux distributions) and the Linux 3.2 source code installed on their machines.

First Failure Data Capture for Linux - Michael Holzheu, IBM

Successful software problem determination depends heavily on the availability of debugging data such as logs, traces, and dumps. More often than not the required information is not readily available resulting in the need to perform life debugging, instrumentation, and problem reproduction. What if this approach is impracticable because the system is not accessible, a further outage is not acceptable, or the problem cannot be easily reproduced?

First Failure Data Capture (FFCD) is a concept that aims at ensuring that all relevant data is collected, retained and reported at the first occurrence of an error. It has been implemented successfully for years in core mainframe components with high availability requirements, such as system firmware or operating systems. This presentation discusses ideas on how the FFDC concept could be applied to Linux.

Beside the battery state, the current PMIC framework provides registers read/write operations only. So the user is obligated to check the documentation and set a specific value of some register to change the state of any regulator.

To solve the problem with driving common functionality - the Driver Model can be used.

The aim of this discussion is to present author's conception about how to use the Driver Model, and get the feedback from the listeners to introduce a common and functional framework architecture.

Cloud Coalescence: The Collision of Virtualization and Containers - Brian Proffitt, oVirt
Until recently, cloud computing has been about virtualization. Virtual machines are at the heart of the cloud, bringing cost savings and flexibility to organizations on a massive scale. But there's a new weather system blowing in: containers. Instead of emulating an entire operating system, containers can run just enough code to efficiently run an application. Containers and virtualization can be construed as competing technologies in the cloud, but in reality they are different parts of the same cloud ecosystem. From oVirt to RDO to Project Atomic, open source projects are leading this new innovation that will transform cloud computing as we know it.

Kubernetes on CloudStack - Sebastien Goasguen, Citrix
Docker is kicking butt and taking names, changing the application deployment landscape and disrupting IT operations practices. With a streamlined application packaging process and an easy deployment scenario, docker is bringing containers back to life and questioning the "traditional" cloud architectures based on virtualization hypervisors. However the true strength of Docker comes of the orchestration of multiple containers, which makes distributed application easier to deploy, monitor, scale and make fault tolerant.

In this talk we will look at Kubernetes the docker orchestration system open sourced by Google. We will show how it integrates nicely with CoreOS a new linux distribution whose sole purpose is to run docker containers. Finally we will show how Docker applications can be managed in the Cloud using Kubernetes, by deploying it on a CloudStack cloud that supports CoreOS templates.

Using Device Tree for VM Runtime Hardware Reconfiguration - Pantelis Antoniou, Konsulko Group
Virtual machines need a way to attach/remove virtual devices on runtime. For instance new block/network devices can be added, memory can be hotplugged removed and so on.

At the moment on the x86 architecture ACPI events are used, and while this can be made to work it is extremely cumbersome. Things are even more difficult on ARM, since there ACPI is still a moving target.

Turns out that by using Device Tree, and overlays, one can simplify the whole procedure by passing around device tree blobs with completely describe all hardware changes in an abstract format.

Join Pantelis Antoniou in explaining how you can use Device Tree to make complex hardware reconfiguration possible, and less troublesome.

Fleet: systemd for Clusters - Brandon Philips, CoreOS
Scaling an application from one machine to two is a difficult. But, with it comes the benefits of fault tolerance and the opportunity to less expensive hardware. To get there you need the right tools. fleet helps you scale work across a group of machines while preserving an interface all developers and sysadmins are familiar with: the init system. Using a simple command line tool you can schedule and run containers across a group of machines and make sure those processes continue to run somewhere in the cluster in the face of machines going down. Learn how fleet can help you manage your machines and the technologies that make it possible.

High Performance NFV Infrastructure (NFVI): DPDK Host Applications with Neutron/OpenStack and VNF Acceleration - Vincent Jardin, 6WIND
The OpenStack community is building automation to create connectivity based on pre-built scenarios of Neutron configuring Linux functions. This creates an open networking environment with NFVI for VMs to run multi-vendor virtual network functions (VNFs). It also prevents single vendor solution lock-in and avoids building proprietary OpenStack plugins of Neutron. With DPDK and packet processing software to create NFVI, it is possible to keep this openness while both introducing performance and avoiding Neutron plugins for proprietary technologies. In this presentation, Vincent will show how DPDK applications can be combined on the host and guest of the network, and compute nodes of OpenStack scenarios, in order to sustain high performance for north-south and east-west traffic that is required for NFV solutions. 100 Gbps of packet processing throughput examples will be demonstrated.

GitLab as an Alternative Development Platform for Github.com - Ralf Lang, B1 Systems GmbH
github.com provides git environments to software projects allowing public source code sharing and management and sharing. Should you need github-like services strictly inhouse, consider GitLab. It runs entirely on your own hardware, allowing you to stay firmly in control of your source code. GitLab provides a web interface for file editing and a clone-edit-merge workflow with code review. Checkouts can be done either via ssh or https. GitLab uses fine-grained access controls to determine who should just be able to report issues, to review code and to actually edit it. Use GitLab CI to create a full-blown continuous integration framework. GitLab CI triggers
automatic software builds and testing upon code changes.
This talk introduces GitLab fundamentals and includes a demonstration of how to set up access controls, code review and the clone-edit-merge workflow.

Tutorial: Setting up ktest.pl - Embedded Edition - Steve Rostedt, Red Hat
ktest.pl is a perl script that lives in the tools directory of the Linux kernel. Although it has "test" in its name, ktest.pl does not suppy any test itself but is a utility to automatically build, install, boot and then run a test on a test machine. The test machine must be a different machine than what ktest.pl is executed on. That other machine can be a virtual machine, and embedded device, or another desktop or server. The requirements is that the host box must be able to remotely reboot the test box, it must be able to read the test box console, and must be able to ssh into the test box.

This tutorial will walk the audience through, step by step, how to set up an embedded board and test it from a laptop computer using ktest.pl. It will include a live demonstration as well.

Hardware Trace - The Ultimate Linux Performance Tuning Tool - Mathieu Poirier, Linaro; Al Grant, ARM

The talk is focused on how the hardware trace features on many SoCs can be practically used by ordinary software developers to investigate Linux performance issues. We'll describe ARM's CoreSight trace technology in enough detail to make the talk useful to people not familiar with hardware trace, but the talk will focus on the practical application of hardware trace to Linux - e.g. how trace can be set up from within the OS, how hardware instrumentation trace (STM) can be used to support existing Linux trace mechanisms such as ftrace, and how hardware-based instruction trace can be configured and visualized to solve problems out of reach of these software-based mechanisms. We'll look at some of the practical issues with using hardware trace and how these can be dealt with.

The second part of the presentation will focus on the new framework proposed by Linaro to support Coresight and hardware assisted tracing in the Linux kernel. More specifically we will go over the solution, the current state of upstreaming and the challenges still ahead. If time permits we will see an example of HW trace decoding using the framework in the Linux kernel.

Packet Trace Modelling and Visualization - Petru Lauric, Freescale
This presentation provides an overview of effective means for correlating and visualizing the trace data collected from a network processor. Trace data directly associated with the network packets is collected at key points in the system, using hardware and/or Linux software mechanisms such as ftrace or LTTng. An abstract model of the packet data flows in the system is used in order to represent the trace-based analysis data in an intuitive fashion. The trace data collected from multiple sources is correlated and analyzed in order to automatically build the data flow model, together with the data flow profile. The model is used to visualize the activity of the traced system along with key metrics such as network packet processing latencies, load balancing factors, packet dropout rates, processed data volume and others. The presentation discusses the trace data requirements, the trace correlation aspects and the need for networking oriented trace data analysis and visualization. The Freescale Packet Analysis Tool, a software tool implementing these trace analysis techniques, is used to demonstrate the presented concepts.

Hardware Accelerated Virtio Networking for NFV - Varun Sethi & Yashpal Dutta, Freescale
Network function virtualization (NFV) leverages standard IT virtualization to consolidate multiple network functions on to a standard platform.The network functions are essentially decoupled from specialized hardware appliances, allowing them to run purely in software, as virtual machines. Network I/O with in the virtual machine becomes extremely critical, especially where network functions handle high traffic rate.
Virtio networking offers a flexible mechanism for sharing I/O interface among virtual machines (also suitable for VM migration). Despite the flexibility, there are performance challenges with virtio (even Vhost-net) for virtual network functions.
In this presentation we discuss the performance issues encountered and how these were mitigated with hardware offloads while running IP forwarding as a virtual network function under KVM hypervisor with Vhost-net networking.

Getting the Most Out of Your Code With Help From the Compiler - Thiago Macieira, Intel
Traditionally, supporting new processor instructions required writing assembly code. Those days, processors are very complex and maintaining assembly code by hand is a hard and tedious task, not to mention that processors evolve and getting the timings right of each generation is better left to the compiler. A little known feature of the compilers is that it is possible to get access to certain instructions from high-level C and C++ code. Yet modern compilers can offer more functionality to help the bold developer write better code. This presentation will present those techniques and show which ones work on GCC, Clang and the Intel compiler. It will also show how to get more information on which intrinsics exist and what they do.

Stealing Chromium: Embedding HTML5 With the Servo Browser Engine - Lars Bergstrom, Mozilla & Mike Blumenkrantz, Samsung
In today's fast-paced development world, HTML5 is an emerging technology which allows for rapid, agile development with a high degree of portability. Many platforms, including Android, are incorporating HTML5 runtimes, which are essentially browser engines, as an alternative to native development. Currently, anyone wishing to embed HTML5 into their application has a very limited number of choices for a browser engine: the Apple-managed Webkit and the Google-managed Blink are the only options. There is a project which aims to create another viable option. Having begun several years ago, the Open Source Servo browser engine is written in the Rust language and is a joint research project with both Mozilla and Samsung invested. This presentation will give some background on Rust, the reasons behind Servo and its architecture, and how to use it as your HTML5 embedding engine.

Embedded Android Workshop - Karim Yaghmour, Opersys
While Android has been created for mobile devices -- phones first and now tablets -- it can, nonetheless, be used as the basis of any touch-screen system, whether it be mobile or not. Essentially, Android is a custom-built embedded Linux distribution with a very elaborate and rich set of user-space abstractions, APIs, services and virtual machine. This one-day workshop is aimed at embedded developers wanting to build embedded systems using Android. It will cover Android from the ground up, enabling developers to get a firm hold on the components that make up Android and how they need to be adapted to an embedded system. Specifically, we will start by introducing Android's overall architecture and then proceed to peel Android's layer one-by-one.

The Service Enabling Wireless Network - Anthony C. K. Soong, Chief Scientist for Wireless Research and Standards at Huawei Technologies Co. Ltd,
There is now no dispute that the wide spread acceptance of the smart phones in the last few
years is currently transforming the mobile communication networks. One aspect is related to the 
movement of data to the cloud so that it can be accessed from anywhere with a variety of devices. This fundamentally redefines the endpoints and time frame for which network services are provisioned.

This talk will discuss two technology trends that will become paramount in the future of mobile 
communication systems: Network Function Virtualization (NFV) and Software Defined Networking 
(SDN). Together they arguably represent the biggest advancement in the mobile communication 
network architecture in the last 20 years, and are fundamentally changing how network services are 
provided. It is the key enabler that will allow the network to be more nimble, flexible and scalable. It 
gives a unique opportunity to re-architect the mobile network to efficiently offer the services in the 
future.

The industry has already moved strongly in this direction; the creation of OPNFV in September of 
2014 is a significant step from the industry in terms of commercialization of these technologies, they will 
increase the rate of innovation, equip the industry for novel business models, and speed up the 
development of the ecosystem that will enrich our lives.

Giving Private Clouds Public Capabilities: Roger Spoor, SurfNet; Dr Jakub Moscicki, CERN; Peter Szegedi, TERENA; Dr. Raimund Vogl, NRW; Frank Karlitschek, ownCloud; Markus Rex, ownCloud (Moderator)

Private, public, hybrid. Clouds now come in three flavors, each bringing with them plusses and minuses. Public clouds are too public, private clouds are too private, and even hybrid clouds are just not quite right. What if we can build a cloud that contains the best of all three worlds.

Frank Karlitschek, founder of the ownCloud project, talks about giving groups of private clouds public cloud capabilities -- while still maintaining their integrity, security and privacy -- and what this could mean to the future of the cloud. ownCloud CEO Markus Rex follows with a panel discussion with representatives from SurfNet, NRW and TERENA about this next revolution.

DPDK: The Data Plane Development Kit Goes Mainstream - John Ronciak, Intel
As the Data Plane Development Kit (DPDK) is used more and more as an ingredient in Software Defined Networking components DPDK needs to move upstream, at least for the kernel component of the DPDK. This presentation will describe the work being done to make the kernel component of the DPDK acceptable for upstream consumption. This will allow the DPDK to be included in Linux distributions which require all kernel components to be upstreamed. There are two different ways of achieve this and this presentation will describe both mechanisms including the pros and cons of both methods.

Building Tools From The Outside In: Bringing User-Centered Design to Embedded Linux - Belen Barros Pena, Intel
Developers tend to think of software in the same way we hang our jeans to dry: inside out. And with good reason: they face the enormous challenge of building software that works. In order to succeed, they must focus on the technology, and not so much on what happens at the periphery of it. Interaction designers deal with a different challenge: they must build software that makes sense to the people who use it. In order to succeed, they must think of software from the outside in, starting from its users, what they want and what they need. This talk is the story of how the Yocto Project built Toaster, its latest application, from the outside in, focusing on its users, what they want and what they need. It will show how user-centered design techniques can be adapted to the particularities of the embedded Linux community, and how they can be applied to help improve embedded Linux tools.

The DRM/KMS Subsystem From a Newbie's Point of View - Boris Brezillon, Free Electrons
The DRM (Direct Rendering Manager) subsystem was first intended to abstract complex GPUs and provide a simple way for user space applications to use GPU capabilities without directly accessing the hardware block.
The KMS (Kernel Mode Setting) API then appeared to simplify and standardize display configuration from user space.
But what about Display Controllers that do not support hardware rendering (3D or 2D) ?

Through this talk, we would like to share our experience in developing and contributing upstream a Display Controller driver for a simple hardware block which does not support GPU rendering: Atmel's HLCDC (HLCD Controller) available on some at91 SoCs.

Building a Secure, Trustworthy and Freedom-Respecting Linux Platform - Matthew Garrett, Nebula
Linux is everywhere, from our pockets to our supercomputers. And as our lives become more entwined with the devices we interact with every day, Linux becomes more attractive as a target for people who want to learn more about us. If we're lucky, they just want our email credentials or credit card details. If we're unlucky, they want the contents of our phone calls and our precise locations. Security is important.

Unfortunately, so far security has often been proposed at the expense of freedom - and vice-versa. People buy locked-down devices because they trust them more. People install replacement operating systems by disabling security features. But this isn't fundamental. We can have both security and freedom. This presentation will discuss how and why it's important.

Digital TV on Linux - Mauro Carvalho Chehab, Samsung
Linux is conquering the world, being spread on al kinds of computers. With the advent of the Internet of Things, it is time for Linux to also enter into embedded devices, including TV sets, Set Top Boxes, etc. However, nowadays, most of the existing Linux DVB applications have incomplete support, as they're based on an API deprecated in 2008. So, they're not fully compatible with the current requirements for newer video standards, like DVB-T2, DVB-C2 and ISDB-T. This presentation's goal is to present the current view by the Linux TV maintainers, and what approach is being taken for it to work in Kernel space and the advances around an userspace library (libdvbv5).

Testing your Full Software Stack on a Single Host With cwrap - Andreas Schneider, Red Hat
Testing your full software stack on a single host with cwrap. Testing network applications correctly is hard. This talk will demonstrate how to create a fully isolated network environment for client and server testing on a single host, complete with synthetic account information, hostname resolution, and privilege separation.

The cwrap project aims to help client/server software development teams to gain full functional test coverage. It makes it possible to run several instances of the full software stack on the same machine and perform functional testing of complex network configurations. Daemons run with privilege separation and required user and group accounts, irrespective of the hosting system. The cwrap project does not require virtualization and can be used to build environments on different operating systems.

ZFS: Love Your Data - Neal Walfield, John Hopkins University
ZFS is (along with BTRFS) a next generation file system. ZFS improves
upon the reliability, flexibility, performance and scalability of
traditional file systems. ZFS better protects your data by hashing
stored data and making updates to the underlying drives atomic, which
RAID, by itself, cannot do. ZFS is flexible: it is a copy-on-write
file system, which enables inexpensive snapshotting of data sets.
This, in turn, enables quickly rolling back a data set to a given
snapshot or even forking a data set. ZFS also supports hierarchical
storage management: it can use an SSD to transparently cache reads.
Finally, ZFS is scalable: some existing installations have over a PB
of storage.

In this talk, Neal Walfield will present ZFS's features and
provide practical advice on how to deploy ZFS both at home and in the
business environment.

Use "strace" to Understand Linux - Harald König, Bosch-Sensortec GmbH
strace is a great tool to analyze running programs, understand what they are doing and how they work (or why they don't), get information about performance aspects and data flows. Harald Koenig shows how using strace both helps to analyze problems and learn more and understand how Linux works by watching the (posix) kernel call interface.

In the tutorial he will show "hands on" in a command line terminal session how to use strace in some examples and explain in detail what the huge amount strace output is all about (up to getting graph charts with gnuplot to visualize and understand timing or statistics data).

Multi-OS Continuous Packaging with Docker and Project-Builder.org - Bruno Cornec, HP
Docker is now a mature techology used for contained execution of applications.
It can also be used successfully to support a Continuous Packaging approach

We will explain and demonstrate how to combine it with project-builder.org in order to help upstream projects distributing seamlessly packages for their code, at whatever step of their development life cycle.

We'll explain how to build a new container, setting it up for this usage, then preparing the delivery of the project content in order to finally build packages in it for the hosted distribution and publishing them for immediate consumption as part of the package management system.

This continuous packaging approach supports multiple repositories type, operating systems/Linux distributions, build environements and repositories managers

Smart VM Scheduling in oVirt Cluster - Martin Sivak, Red Hat Czech
The oVirt project allows efficient management of virtualized datacenters. Deciding what machine should host a certain VM is one of the important functions of the management platform. Unfortunately it is also one of the complex ones, because there can be many rules governing the placement policy and there is a time limit in which a VM has to be started or migration initiated. Till now each VM was considered separately and that caused fragmentation of free resources.

We are about to present a new solution to this issue in this presentation. We have started a cooperation with the OptaPlanner team that develops an optimization engine based on probabilistic (soft computing) algorithms. This means that oVirt will feed situation updates to an optimization service and continuously receive improved solutions back. It will then use the precomputed results for rebalancing the clusters.

Tuning Android for low RAM - Chris Simmonds
The 4.4 KitKat release includes the results of “Project Svelte”: a set of tweaks to the operating system to make it run more easily on devices with around 512 MiB RAM. This is especially important for people working with Android Wearables and “Embedded Android”, that is, implementing Android on devices at the lower end of the Android ecosystem.
A large part of the problem is knowing how much RAM is really being used. Android offers a variety of tools for the purpose: procrank, procmem, meminfo and procstats, which I cover in the first part of the talk. In the second part I take a real-world example and show the practical steps you can take to optimize memory use including tuning the size of the Dalvik heap, enabling KSM (Kernel samepage merging) and swap to zRAM.

u-root: A Go-Based binutils Providing Scripting Convenience and Compiled-Program Performance - Ronald G. Minnich, Google
U-root is a Go-based binutils intended to replace Busybox. All programs and libraries are present in the file system as Go source, and are compiled when run. They can be compiled to a ramdisk, our current usage; or, if preferred, to persistent storage. To update the binaries requires no make steps; one can just rm -rf /bin/* and, the next time a program is run, it is recompiled (in < 1 second).

All programs and Go packages are present in u-root as source. There are 16 binaries comprising the Go toolchain. Further, due to the layout of u-root, it can be used on any Go-supported architecture and it will work. A USB stick containing u-root can be used on ARM, x32, or x64.

Many tools remain to be written; for needed tools we have not yet written, Tinycore Linux .tcz packages will be used in u-root via the provided tcz command. U-root was also designed to fit in a BIOS Flash part.

[REPEAT] Overcoming Obstacles to Contributing to Linux - Tim Bird, Sony Mobile
This is a repeat of the initial presentation that some attendees were unable to see due to limited seating (and fire regulations).

Many companies struggle with contributing to Open Source projects. This talk will identify key difficulties that many large companies face in making contributions, and provide tips and lessons learned for overcoming these obstacles. Some of the difficulties discussed will be: version gap, expertise problems (an example of which is the "proxy problem"), wrongly-abstracted code, process mismatch, and social and attitudinal barriers. This will not be yet another talk on CodingStyle, but a more high-level look at structural problems inside companies and the industry that prevent meaningful engagement within the open source community.

The goal of this talk is to help individual developers and companies identify and implement practices that will accelerate their participation in open source, so that they can enjoy more of the value of open source besides just the open code base.

Improving Application Responsiveness and I/O Latency With the BFQ I/O Scheduler - Paolo Valente, University of Modena and Reggio Emilia, Italy
BFQ (Budget Fair Queueing) is a storage-I/O scheduler with some new or
improved features with respect to existing research and production
schedulers. One of the nice features of BFQ is that it guarantees a
high application responsiveness, regardless of the background I/O
workload. BFQ also guarantees a low latency to soft real-time
applications, such as multimedia players. These features do not come
at the cost of any loss of throughput, with respect to existing I/O
schedulers. On the contrary, BFQ even outperforms the latter with some
combinations of workloads and devices. Finally, BFQ seems to be on the
right track to be merged into mainline, and replace the current
default I/O scheduler. In this presentation, Paolo Valente will show
BFQ in action, and describe some of its inner workings.

Demystifying Android's Security Underpinings - Karim Yaghmour, Opersys
Android has relied from its early days on the Linux kernel for sandboxing the processes it runs. Yet, the permission model presented to app developers is significantly different from the Unix permission model. What's the relationship between those two models? How is Android's app security framework tied to the Linux kernel's security model? More recently, Android has started using SELinux and has been extended by SEAndroid to support similar functionality. How is SELinux used by Android and what is SEAndroid about? Furtheremore, how does Android provide support for multiple users?

This talk will explore Android's security model in great detail and explain how the functionality found in the kernel is used to isolate user processes and the SE enhancements are leveraged by Android. As we'll see, there are quite a few moving parts= in Android's security model.

Embedded GPUs: A Case For Open Source Drivers - Lucas Stach, Pengutronix
GPUs are traditionally one of the last strongholds for binary drivers. While most vendors respect the GPL and provide an open-source kernel driver, most of the functionality is hidden inside binary userspace OpenGL libraries. In this talk Lucas will present his experiences with integrating binary graphics drivers into embedded Linux systems, intended as a neutral review of the technical shortcomings and hurdles one has to overcome while striving for an acceptable user experience. He will then show how open source drivers are able to help solving those problems and how they could be used to actively drive innovation.

As this kind of hardware usually comes with some kind of performance monitors, it can be more than useful to allow user to use them. Unfortunately the perf infrastructure is much less suitable for this, requiring some workarounds and simplifications. I will show what has been done so far, using "uncore" PMU drivers x86 and ARM "CCI" and "CCN" interconnects as example and discu
ss what could be done to improve the situation.

x86 Instruction Encoding and Nasty Hacks We Do in the Linux Kernel - Borislav Petkov, SUSE
I have always wanted to understand x86 instruction encoding in detail but never gotten around to it. Of course not, who has time nowadays?! So, in order to force me to do it, I decided to write an x86 instruction decoder.

This talk attempts to show what I have learned in the process and how instruction encoding is done on x86.

As a practical aspect, the decoder I've scratched together tries to verbosely show some of the crazy low-level hacks^Wtechniques we do in the Linux kernel like alternatives patching, jump labels, exception tables, etc - they have a lot to do with deep knowledge of x86 instructions and how code is generally laid out in the binary kernel image. Maybe this talk can help shed some light on the whole fun that's happening under the hood in the kernel and so many are missing out on. And maybe it'll make it more interesting and palatable to people.

Extending Secure Boot to User Space with Linux Integrity Subsystem - Dmitry Kasatkin, Samsung Electronics
Secure boot allows only signed firmware, boot loader and Linux kernel to run on the device. User space programs starting from 'init' run unverified. Linux integrity subsystem will make it possible to extend secure boot to user-space by signing and verifying executables, data, and file metadata. It allows to protect critical parts of the system and make sure that even root cannot change them. Presentation will cover existing and new functionality of the integrity subsystem and show practical steps how to protect the system using digital signatures.

Finding Stupid Vulnerabilities in Binaries - Armijn Hemel, Tjaldur Software Governance Solutions
Contrary to what people want to believe devices running Linux are not safe because they run Linux: there is a ton of very crappy and insecure code available for Linux and unfortunately for us it is being used on production devices. This is especially evident in the consumer electronics industry where companies under enormous time pressure do not pay much attention to security, because security is not a feature the customer asked for. The result is that there are gaping holes in many networked devices that are ready to be exploited. In this talk I want to present some new experimental tooling to help discover the obvious security bugs.

GitHub + F/OSS => 1 Million SPDX - Nuno Brito, TripleCheck
SPDX is an open format for describing software licenses, contents and ownership. It is a simple text document with great benefits for software governance. But have you ever seen one? Despite being an open standard, there aren't many available to public. Using only Linux, GitHub and F/OSS tools, Nuno and Ben were fuelled to prove that SPDX is also applicable to everyday projects. As result, the first large-scale SPDX Internet archive came to exist. Join this presentation to learn how over 1 million SPDX documents were created using open data in large-scale repositories and how easy it is to create one. From now forward you'll be able to express the licenses in your code automatically and create licensing transparency by yourself.

OpenStack High Availability: Are We There Yet? - Florian Haas, Hastexo
OpenStack has come a long way since it had its first discussions around infrastructure high availability in early 2012. Since then, every single OpenStack vendor has come out with their own flavor and understanding of high availability.

But how do they compare? What can and can’t you do with them? And which should you choose?

This presentation compares the high availability support we currently have in OpenStack products from Red Hat, SUSE, Canonical, Mirantis, Cisco, Piston and others, from an independent and vendor-neutral perspective. It discusses advantages and disadvantages, deployment options, and suitable and not-so-suitable use cases.

Systemd for Embedded Linux - Challenges and Opportunities - Michael Olbrich, Pengutronix
System V init or similar home grown solutions are still used for the majority of the embedded Linux systems. Systemd is seen as 'too large' or only useful for server and desktop systems.
In this presentation, Michael Olbrich will show that systemd certainly has a place in an embedded Linux system. How it can be used to replace home grown solutions to typical problems in embedded systems and improve the reliability of the system as a whole. Why leaving the well known environment and taking the effort to learn about a quite different init system is well worth the effort. However, it should not be forgotten that systemd is a complex piece of software with a long list of requirements. So this presentation will also take a look at what's necessary to successfully integrate systemd into an embedded Linux system.

USB and the Real World - Alan Ott
The Linux kernel provides a robust implementation of both the host and device side of USB. While we can all easily quote the theoretical throughput of each USB speed defined by the specifications, the numbers can be quite different in practice, with variation due to the device class and implementation, the format and structure of user data, and the implementations of both the driver and user space software running on both the device and host. In this presentation, Alan Ott will explore some of the common pitfalls of USB software related to performance on both the device and host sides and will show some techniques to maximize throughput. Analysis will be performed using several different USB device controllers as well as tools such as a USB hardware analyzer. In addition, ftrace with kernelshark will be used to find performance bottlenecks on both the the kernel and user space sides.

UserModeLinux Status Report - Richard Weinberger, Sigma Star GmbH
UserModeLinux (UML) was one of the first virtualization technologies for Linux, also known as "a port of Linux to its own user space ABI". Currently almost everyone is using KVM, XEN or VMware to virtualize Linux. But UML still exists and has users. Richard observed that many kernel developers have no clue how UML works and therefore break it from time to time without even noticing.

In this talk he gives an overview of UML and its internals. The key points are:
  • Why UML has still users and what the use cases are
  • How to build and test it
  • On which other sub systems it depends (and how it can break)
  • How it works
  • Emerging new features like SMP support and x86-compat mode
  • Limitations and problems of the current implementation
  • Discussion with other kernel developers how Richard can help that UML does not hinder others work

Where is My Crystal Ball? - Daniel Lezcano, Linaro
The increasing part of the embedded systems in the linux ecosystem forces the kernel developers to take into account an energy efficient approach when bringing a new platform. The different energy frameworks are standalone sub-systems acting independently and in a opportunistic way when there is nothing to do on the system. The energy efficient scheduler wants to integrate all these energy components in order to act proactively by having a better knowledge of the potential energy saving for each scheduling decision it will take. This presentation describes a new paradigm where the events occurring in a acceptable interval are considered predictable and can be tracked per task. It will describe the IO latency tracking fully integrated in the scheduler and, thanks to better predictions, allows to get ride of the cpuidle's governor by directly choosing an idle state from the scheduler.

Cut Power Consumption by 5x Without Losing Performance: a Big.LITTLE Software Strategy - Klaas van Gend, Vector Fabrics
Multicore silicon architectures are everywhere. Until recently, these architectures where homogeneous. Recent big.LITTLE silicon aims to trade-off power consumption against computational throughput.
Typically, the big cores are used for high performance tasks like web browsing, games and image processing. Unfortunately, the usage of big cores comes with high power consumption levels - resulting in a disappointing battery life.
The little cores have a much lower power consumption level, but typically used in ‘idle mode’.

In this presentation we show how we reworked Chromium to use all available ‘little’ CPUs in a parallel fashion to achieve a highly responsive browser without incurring the power penalty of using the big cores. Experiments with real websites show that this results in a 5x power consumption reduction - at the same performance.

Software Patent Litigation: What Have We Learned? - Deb Nicholson, Open Invention Network
The huge increase in software patent litigation over the last 15 years has produced reams of articles, cost fortunes and even snagged the US President's attention. But when something goes on for long enough, it also produces data -- lots of data. So what have we learned?

Non-practicing entities are growing and litigation costs increase each year, but that's hardly the whole story. Ms. Nicholson will examine data from academic and industrial sources to see what it all means for Linux, Android GNU and the rest of the free and open source community.

Continuous Integration Using Docker & Jenkins - Mattias Giese, B1 Systems GmbH
Jenkins is often found inside a Continuous Integration/Delivery infrastructure. It can be used to automatically test each change set as soon as it occurs in a monitored code base. It is often linked with deployment tools like Vagrant to create a complete testing environment. Yet, here is a small drawback: launching and provisioning virtual machines for each change set increases the time for a test run to complete. With the help of Docker, provisioning of a testing environment is done in seconds, decreasing the time it takes to provide meaningful feedback to the developer. This talk describes two scenarios where automatic integration testing with Docker increases the productivity of admins and developers. The first one describes how an admin may perform integration testing of Puppet modules, a second one implements integration testing of a web app consisting of a Web and database server.

Open vSwitch and DPDK - Jesse Gross, VMware

DPDK (Data Plane Development Kit) has generated a lot of excitement by demonstrating that it is possible to do high speed networking purely in software. However, as the name implies, DPDK is a building block and set of tools rather than an application for end users. In order to be useful, it needs to be built into existing software.

Open vSwitch is already widely used in software based networking due to its programmability, flexibility, and integration with other tools. In addition, due to its portability, OVS is relatively easy to adapt to new types of data planes, making the two a perfect fit.

DPDK has many similarities to existing platforms used for Open vSwitch but also some marked differences, especially if the best possible performance results are to be achieved. Come hear the experience of getting OVS running on DPDK, where we are, and what still needs to be done.

Cycle Accurate Profiling With Perf - Pawel Moll, ARM
A lot of silicon in modern SoCs is doing nothing most of the time, being dedicated to so called "tracing". This used to be domain of well known, expensive and proprietary tools, but in the last year there has been more and more interest in providing kernel infrastructure driving it, however this is *not* focus of this presentation :-) Instead, I will show one of possible ways of consuming the vast amount of data obtained from the mentioned resources, mainly on processor trace. This data usually provides detailed data about instructions being executed with minimal (in some cases even no) performance overhead. After being decoded, it allows generation of very precise (not just sample based) profile of executed code. I have been working on using the user space perf tool to use this data and want to present results, discussing possibilities and limitations of the method.

EFL – A UI Toolkit Designed for the Embedded World - Cedric Bail, Samsung
Enlightenment Foundation Library is a set of libraries designed to use the full potential of any hardware to do great UI. It has been designed with the embedded devices in mind, but it is a desktop class toolkit. Being done in C, it is providing a stable API/ABI, high efficiency, low memory and low battery usage for all kind of Linux device. Enabling development of modern UI adapted to any hardware that run Linux. These are the reason why Samsung use it in its Tizen devices. This talk after a short overview of what this libraries cover, will focus on this year improvement and where it is heading. It will also be an opportunity to learn about project around EFL that will help people develop product with it.

Automated Linux Kernel Crash Infrastructure - Eye In the Digital Sky - Igor Ljubuncic, Intel
While robust and generally stable, the Linux operating system may suffer from occasional bugs in the kernel stack, sometimes leading to an irrecoverable condition known as kernel oops. The condition can translate into a system panic, resolved only by a reboot. In time-to-market critical data center environments, kernel crashes can impact the productivity of compute resources. Resolving bugs in the kernel code that cause the panic situations is of paramount importance. In homogenous environments, where a single operating system dominates the install base, individual bugs can potentially manifest on all machines in a very short period of time. In this presentation, Igor Ljubuncic presents on how Intel’s IT transformed its business with an automated Linux kernel crash collection, analysis and reporting infrastructure, designed to address stability of the system’s core – the kernel.

Present and Future File Serving with Samba - Michael Adam, SerNet GmbH
Samba is the most important open source SMB file serving software, and arguably, one of the most important SMB implementations out there, being shipped with all major Linux distributions and part of many big and small storage appliances. A lot has happened in Samba's file server in the last couple of years, and this talk first describes file serving with Samba in the age of Samba 4: Samba 4.0 was released as the Active Directory server release, but it was also a very big file server relase with a lot of new changes and new features.

With the introduction of SMB version 3, Microsoft moves from pure workstation workload focus to server workloads, aiming to partly replace block storage. In particular Microsoft catches up with Samba/CTDB to offer all-active clustering. The second part of this talk describes current work in progress in this area and where the Samba file server is heading.

Open Source in Storage: Is it Here to Stay? - Nithya Ruff, SanDisk
There was an important article in Forbes late last year asking the question “why has open source not taken over Storage”. The article went on to say that Open Source was more computer science than engineering that was needed to support mission critical storage. I take a deeper look at the transformation that is happening in storage and examine the question of the role of open source in storage. I look at the drivers driving growth and adoption of open source in storage as well as the state of open source supply. Cover OpenStack, Object Storage, and Cloud Storage where Open Source is here to stay and address how the collaboration between commercial companies and open source and the role that consortium has played to create a datacenter ready open source.

Clocker - Migrating Complex Applications to Docker with Apache Brooklyn - Andrew Kennedy, Cloudsoft
Deploying enterprise-class distributed applications to Docker containers spanning multiple hosts is tricky. Dealing with port forwarding, firewalls and injecting configuration into containers for inter-dependencies are just some of the problems.

We will show how Clocker uses Apache Brooklyn's cloud abstractions to simplify the deployment and management of a complex application to a virtual Docker infrastructure. Brooklyn will create and maintain the required Docker containers in the right locations for your application, and control and manage the software and services using policies to scale both the application and infrastructure based on their state.

We will demonstrate deploying simple multi-tier web applications and also a complex financial risk analytics application from OpenGamma, onto a Docker infrastructure.

OpenStack REST API: Compatible or Consistent - Ken'ichi Ohmichi, NEC
The community of OpenStack Nova project is discussing the design and the purpose of a new RESTful API now. The API is called "Nova v3 API". The features of v3 API are "consistent API naming", "strong input validation", and "clean code". We already started developing v3 API one year ago, and the most part has been implemented. However the code removal of v3 was proposed, because we have renamed many API attributes for the consistency and the fact will cause a lot of backward incompatibility issues to Nova API users. In addition, there are huge amount of RESTful APIs as Nova API, the developers concerned the maintenance cost for keeping both API versions(v2 and v3). Ken'ichi is proposing an idea to solve the problem. He will show the mechanism of v3 API and the idea, and also show how to join OpenStack development community.

Open Source: The Customer Revolution Will be Cloudified - John Mark Walker, Red Hat
Open Source was a phenomenon made possible by the will of the customer and end user, pushing them up to the same status as developers. Cloud computing as an industry phenomenon is built almost entirely on open source pieces, but ironically (or perhaps, perversely) is used to create proprietary services. One could say that cloud computing is the revenge of the developer.

This talk discusses how the four software freedoms allowed customers and end users to achieve a more level playing field and provided a solid foundation on which innovation flourished. Innovation was an interesting by-product, not something pursued. The lessons learned from open source innovation should inform our choices in cloud-y computing, but cloud is currently dominated by proprietary services and obfuscation beyond the public API. Can we arrange the pieces once again such that innovation is an interesting by-product of processes and governance designed to give everyone a seat at the table?

Leveraging Open-Source Power Measurement Standard Solution - Patrick Titiano
A major issue the community faces is the lack of power measurement (PM) instrumentation, coupled with poor integration: development boards not designed for it, expensive high-precision lab equipment not accessible to hobbyists (plus limited Linux support), limited low-cost solutions (precision, sampling rate) to monitor high-performance SoC (System On Chips) platforms (e.g. smartphones, tablets, IoT, …). After a brief introduction to the problematic (PM techniques, sense resistor / ADC selection, ...) and a comparative study of existing solutions, this presentation will focus on a new upcoming initiative to close these gaps and bring a full-blown multi-channel but low-cost power (and temperature) measurement equipment to the community, including the definition of an open standard PM connector.

Ftrace Kernel Hooks: More Than Just Tracing - Steven Rostedt, Red Hat
The function hook facility of ftrace is what makes ftrace stand out from other kernel tracers. The ability of live modification of the kernel to convert a nop into a ftrace callback has revolutionized tracing inside the kernel. Because it is dynamic, ftrace gives you the ability to chose what functions are to be traced, as well as tracing all functions within the kernel. This talk is not about tracing though, it is about what is coming in the future and the hurdles that needs to overcome and how it will be done. The ftrace function hooks allows for "hijacking" of a function. That is, when the function is called, the hook can intercept the call and divert it to call another function. Live patching such as kgraft and kpatch were built on this facility. To use these new features of ftrace, more must be done. This talk will go over how the hooks work and what more needs to be done.

Sisyphus is Happy: Experiences From the Fight for Software Legal Compliance - Alexios Zavras (zvr), Intel
Nowadays software is usually a combination of own-written code and FOSS; in some cases it also contains proprietary parts licensed under non-FOSS licenses. This talk will present lessons learned while building a corporate software legal compliance system that is sensitive to the needs of developers while still pleasing the lawyers. It will touch upon different aspects of the set of processes and mechanisms used. Such mechanisms exist to provide answers to questions such as how can FOSS be used; how can FOSS be integrated; and how can FOSS be released? It is obvious that the task of legal compliance involves developers as well as people from legal professions; therefore an important part of structuring any system or set of processes has to be the satisfaction of both these groups of users.

Community Best Practices: Understanding and Using the Developer Certificate of Origin - James Bottomley, Parallels
Now that the DCO is free from the kernel (http://developercertificate.org/) it can be used in any project. This talk begins with why you need a Contributor Agreement (CA) in the first place, explores some of the history and reasons for the various CAs and why Linux was forced to adopt the DCO nearly ten years ago. We will contrast the ten years of DCO experience against some other projects which use more specific CAs and explain the benefits and pitfalls. We will also give advice on best practices around using the DCO, what else is required to make the DCO work correctly and what problems still remain. Finally we will synthesise some conclusions about how much protection the DCO provides and some general advice about whether an additional CA is needed for your project.

The audience is anyone interested in setting up an open source project, participating in an existing open source project or people who just want to be aware of best community practices around projects. 

Understanding the DCO better reduces fragmentation and increases the probability that community projects won't trip over CAs or will end up alienating potential contributors for non technical reasons.

Integrating Linux and the Real-Time ERIKA OS Through the Xen Hypervisor - Arianna Avanzini, University of Modena and Reggio Emilia
Modern cars, as well as aircrafts, are equipped not only with more and more complex control systems, but also with increasingly advanced user interfaces and infotainment systems. The growing computational demand of these applications can now be met only with multi-core systems, which are actually supplanting single-core ones. Also, safety-critical and non-safety-critical components must be isolated from each other. In this presentation we show a double-OS system, running on a dual-core ARM platform and using the Xen hypervisor to run, in two isolated domains, (1) the automotive-grade ERIKA Enterprise OS, a small-footprint real-time OS suitable for safety-critical control tasks, and (2) a full-featured Linux OS, which is then able to support any complex user interface or multimedia service. The system also provides a basic, safe communication mechanism between the two operating systems.

Avoiding the 1000 Euro VM in Your First Cloud - Tim Mackey, Citrix
Today everyone is talking about clouds, and a few are building them, but far fewer are operating successful clouds. In this session we'll examine a variety of paradigm shifts IT makes when moving from a traditional virtualization and management mindset to operating a successful cloud. For most organizations, without careful planning the hype of a cloud solution can quickly overcome its capabilities and pre-existing best practices can combine to create the worst possible cloud scenario -- a cloud which isn't economical to operate, and which is more cumbersome to manage than a traditional virtualization farm.

Key topics covered include:

- Successful transition of operational and management paradigm
- How the VM density of clouds change Ops
- What it means to monitor the network in a cloud environment, at hyper-dense virtualization levels
- Preventing storage costs from outpacing

The OpenNebula Model for Cloud Provisioning and Management - Javier Fontán, OpenNebula
On-premise private clouds require simple, powerful and flexible mechanisms to manage the access privileges to the infrastructure and to dynamically allocate the available resources. OpenNebula's quest for simplicity touches every aspect of the software, and a great effort has been put into the provisioning model. A smooth experience for users entails a proper design of the concepts, ironing out the flow of day to day operations, as well as proper tools for the administrators to manage its cloud. OpenNebula features on-demand provisioning of Virtual Data Centers (VDCs), which are containers for the execution of virtual resources that allow a complete isolation of users, organizations or workloads. This innovative provisioning model offers an integrated and comprehensive framework for resource partition, allocation and isolation in federated data centers and hybrid cloud deployments.

High-Speed Data Acquisition With the Linux I/O Framework - Lars-Peter Clausen, Analog Devices
The Linux IIO (Industrial IO) data converter framework has so far only supported low-speed converter devices (samplerate < 50kHz). From a framework point of view it is desirable though to handle low-speed and high-speed converter devices via the same (or a very similar) interface as this will allow sharing the supporting infrastructure. This talk will discuss the design challenges of adding support for high-speed data acquisition devices (with sample rates up to multiple GHz) to the IIO framework and how these challenges have been addressed. It will give an introduction to the new APIs (both kernel and userspace) that have been added to the IIO framework to accommodate the requirements of high-speed converters. The talk will also include an overview of the tools that have been developed around this new APIs.

[REPEAT] Transactional Device Tree & Overlays: Making Reconfigurable Hardware Work - Pantelis Antoniou, NVIDIA
This is a repeat of the initial presentation that some attendees were unable to see due to limited seating (and fire regulations).

Device tree has been decreed as the modern way to describe a board's hardware, but falls flat when faced with the problem of hardware that it-self is reconfigurable. While this is more prevalent on systems employing FPGAs, it is actually a problem for low-end boards like the Beaglebone & any other device that exhibits flexibility in configuration its interfaces. Limitation of in-kernel DT support make it hard to apply batches of changes and revert in need be.

The new Transaction Device Tree + Overlays patch-sets overcome these problems and are intended to land in mainline during the next few major revisions.

Pantelis Antoniou will review the extensive changes and will discuss the major changes coming in the DT support of the kernel.

ACPI And Device Trees - Friends Or Foes? - Rafael J. Wysocki, Intel OTC
ACPI was introduced when hardware compatibility with the IBM PC became insufficient to maintain the PC ecosystem. It allowed a single binary OS image to run on various platforms using the same CPU architecture, but not exactly hardware-compatible with one another. Today, Device Trees are used to address the same platform fragmentation problem in the ARM ecosystem. Of course, there are differences between ACPI and DT. Unlike DT, ACPI had a difficulty with passing arbitrary data to the OS, but that limitation is now being removed. With ACPI now able to provide the same data as DT, a need has arisen for a shared firmware-interface-agnostic specification of hardware properties. Similarly, the platform firmware interface access for device drivers in the OS should be unified, so the same driver can work equally well on systems with ACPI or DT. I will discuss work toward that goal in Linux.

Automatic NUMA Balancing - Rik van Riel, Red Hat
In NUMA systems, each CPU has its own bank of memory, resulting in fast access to local memory, and slower access to memory elsewhere in the system. Recently a mechanism has been implemented in the Linux kernel to automatically run programs near their memory, and to move memory to near the programs using it. This presentation explains why computers are built this way, why NUMA locality matters, how the automatic NUMA balancing kernel code works, what it can do, and what kind of performance improvements have been observed. This presentation is also a good opportunity to discuss recent and future developments for the automatic NUMA balancing code.

Collaboration Beyond Development - Co-opetition and the Long Game - Shane Coughlan, OIN
Collaboration around Open Source has lead to common strategic goals for SMEs and multinationals across the world. It is characterised by a social movement of co-opetition - simultaneous competition and cooperation - where companies compete on products but collaborate on platforms. The underlying concept is “Smart Innovation” that empowers everyone to make better products and services. This leads to a corresponding refinement in the way many companies approach “IPR” strategy. Such refinement initially focused on acceptance of Copyright licenses like the GPL but has evolved to include other areas of business strategy. Most strikingly, today the Linux System has the largest patent cross-license community in the world by a wide margin, with EMEA companies being some of the most numerous and active participants. This talk unpacks what is happening and discusses where we are going next.

Kernel Event Tracing on the Mainframe - Michael Holzheu, IBM
Because mainframes traditionally run mission critical workloads, serviceability has always been of high importance to the platform. Customers expect that the root cause of a problem can be found with the first set of debug data that is collected. Reproducing the error is not welcome and must be avoided. With this in mind, IBM provided the s390dbf kernel tracing infrastructure when Linux was ported to the s390 architecture at the beginning of 2000. This was about eight years before Linux ftrace and tracepoints were integrated into the upstream Linux kernel. In some areas, tracepoints offer advantages, for example, per-CPU trace buffers or an event streaming capability. Yet, tracepoints do not offer all features that are needed for s390. This presentation reviews the two tracing features and shows what would have to be added to tracepoints to achieve the same functionality as s390dbf.

An Update (and Demo) on Techniques to Manage libvirt/QEMU-Based Virtual Machine Snapshots and Disk Image Chains - Kashyap Chamarthy, Red Hat
Managing QEMU overlay-based virtual machine snapshots can become cumbersome over a period of time. With each new snapshot, a new QCOW2 overlay file is created -- this can become an overhead of tracking multiple disk image files. Understanding the ability to manage multiple disk image chains efficiently will help lower this overhead.

This talk aims to explore some of the recent improvements in QEMU and libvirt projects that address this need of advanced disk image management. More specifically, we'll discuss -- shortening disk image chains, snapshot merging, live backup of entire disk image chain, gracefully reverting and deleting snapshots. We'll also see how some of these underlying concepts are used in higher-layer projects like OpenStack to create and manage snapshots. This session also includes a demonstration of some the snapshot management techniques discussed.

[REPEAT] 12 Lessons Learnt in Boot Time Reduction - Andrew Murray, Embedded Bits Limited
This is a repeat of the initial presentation that some attendees were unable to see due to limited seating (and fire regulations).

It's not uncommon to produce embedded Linux based devices that end up with long and inconvenient boot times - yet eliminating boot time delays can be difficult and time consuming. Furthermore once a minimal boot time has been achieved it's often just as difficult to maintain it through subsequent software development.

In this presentation, Andrew unfolds 12 keys lessons learnt in his experience of boot time reduction. These lessons provide an insight into the common causes of boot time delays, why they are present and how they can be overcome. In describing these lessons Andrew will also take you on a journey that indicates why file system benchmarks should probably be ignored (with respect to boot time reduction) and a journey that illustrates that the Linux kernel is rarely the worst offender for boot delays.

How to Design a Linux Kernel API - Michael Kerrisk, man7.org
The Linux kernel-user-space API is littered with design errors: APIs that are non-extensibe, unmaintainable, overly complex, limited-purpose, violations of standards, and inconsistent. Most of those mistakes can't be fixed because doing so would break the ABI that the kernel presents to user-space binaries. To further rub salt into the wound, kernel-user-space APIs are often buggy when first shipped.

Thus, it's important to get API designs right the first time. Taking (good and bad) examples from past APIs, I'll cover a number ideas on improving the design of future kernel user-space APIs. Those tips are relevant both for kernel developers producing the APIs and for user-space programmers looking at what kernel developers are serving to them. I'll also look at some strategies that developers can pursue in order to get help with improving the designs of APIs that they are producing.

Managing License Compliance and Open Source Software Logistics for Cloud-Based Applications - Kirsten Newcomer, Black Duck Software
Software deployment is moving rapidly from “on premises” to service-based and cloud models–requiring developers to upgrade knowledge of OSS licenses. Most OSS licenses were developed around traditional delivery models; however, these models didn’t anticipate advances in cloud computing, which has resulted in some popular licenses having implications for SaaS. With the shift to SaaS and cloud, this new class of licenses (including the AGPL) has become increasingly important. In this presentation, Kirsten Newcomer will review the application of OSS licenses, particularly AGPL and similar licenses, to these services. Newcomer will also review reasoning behind the proliferation in projects with AGPL-type licenses, the new compliance and license complexities introduced by Docker, and the logistical challenges inherent in managing open source in SaaS applications.

P Factor – Innovate Your Interactive Experience - Igor Ljubuncic, Intel
Intel’s chip design is a unique setup where interactive work by engineers is conducted through VNC connections to high-end multi-user servers, with heavy dependence on NFS traffic and data. A continuous and exponential increase in multi-core and memory capacity in recent years creates a challenge - how many users can comfortably work on a typical server in the interactive work model? Indeed, interactive users observe and report degraded experience and slowness in their sessions, although CPU and memory are hardly utilized. In this presentation, Igor Ljubuncic elaborates on a novel approach to studying user experience on interactive machines and developing a proactive framework for measuring and optimizing performance. Igor presents a formula named P Factor for objectively determining interactive usage slowness in I/O operations.

Tutorial: Build a Fully FOSS Cloud with OpenNebula - Javier Fontán, OpenNebula
OpenNebula is a fully open-source cloud management platform that combines a simple, but flexible and powerful, virtualization manager that supports traditional IT features such as fault tolerance and failover, with the dynamic provisioning, elasticity and multi-tenancy of the enterprise cloud. The aim of this tutorial is to learn how it works and how to install it from scratch on CentOS as the operating system. The experience of building a real production ready and scalable Cloud is much more than just installing a Cloud Platform, that is why, thanks to OpenNebula's simplicity, we will discuss how to further integrate it with many Open Source technologies, like Ceph for the Virtual Machine storage or Ansible to bootstrap it all.

Attendees will build the cloud in two CentOS virtual machines in their own laptops using VirtualBox. Remember to come to the tutorial with VirtualBox installed and with the virtualization extensions enabled!

Secure and flexible boot with U-Boot Bootloader - Marek Vašut, DENX
Being able to ensure the Linux-based system we are booting is not corrupted or was not tampered with is becoming a more and more pressing issue. Marek will talk about building an ARM system based on U-Boot bootloader and Linux kernel, where one can be sure that the system will either boot the Linux kernel intact or will refuse to boot in case of an uncorrectable error.

This will be achieved by explaining how to use UBI to prevent corruption of the bootloader and kernel itself in combination with the fitImage kernel image format. The fitImage allows for both cryptographic verification of the kernel image integrity with a strong hash as well as appending an RSA signature, thus allowing to trap both silent corruption due to memory deterioration and tampering attempts.

Finally, Marek will outline the possible pitfalls which can hamper such reliable designs.

First Glimpse at Shingled Drives - Hannes Reinecke, SUSE Labs
Recently storage vendors have advocated 'shingled media recording' devices. These drives are estimated to provide larger capacity than existing drives, but at the same time introduce a new access model. Hence it will not be possible to use them as all-purpose drives without modifications to the storage stack. For Linux there are two different proposals for handling these devices, either by using modified filesystems or by adding a device-mapper module.
This talk gives an overview about the technology behind shingled media recording and the proposed changes to the linux storage stack.
I will also present the results from running a modified stack on a pre-production device and its implications for further development.

In large organizations, identities need to be managed centrally, both to avoid the overhead of maintaining multiple user databases and to support seamless access of all members of the organization to systems and services, while being able to control the access in flexible ways.  Linux-only solutions now evolve to integrate with Active Directory, single-organization setups expand to federate with other identity providers, and OS-level identity, authentication, and access control become usable for applications and higher pieces of the infrastructure as well. In this talk, we will explore new setups made possible by latest development in cross-forest realm trust support in FreeIPA and sssd, federated identity and authentication providers, and using both not just for ssh and other operations in operating system, but consuming the results in infrastructure management tools and end user Web applications alike.

Women's Resume Writing Workshop - Leslie Hawthorn, Elasticsearch

While Linux jobs may be plentiful, candidates still need to ensure their resumes are primed to meet the expectations of corporate recruiters and hiring managers. As part of their efforts to encourage more diverse participation in the Linux and cloud computing communities, The Linux Foundation has teamed up with Leslie Hawthorn to offer a resume writing workshop for women.

During this workshop, Leslie will offer her insights from her time in the trenches as a corporate recruiter for Google's Linux Kernel engineering team. The workshop is divided into two segments. The first focuses on common pitfalls when preparing your resume that women may find themselves encountering more often than men. She'll go over three sample resumes from highly accomplished women she knows and do before and after feedback session with the workshop participants. For the second part, we'll break into small groups and augment each others resume and do a before and after look.

ring at least three print outs of your resume plus your willingness to let your awesomeness shine through. You can be humble tomorrow, when you're not working on your resume! You do not need to sign up for this workshop to attend. Final timing and location will be announced soon.

KVM on Grid: Shaken, Not Stirred - Raphael Sack, Intel Corporation
Let’s say you have 10,000 Linux servers. Now, let’s say you need to upgrade these servers to version+1. How long is this effort going to take? Now consider the following scenario: All these servers are running 24/7 business critical tasks. Any disruption will cause significant delays in project timetables, and incur financial costs. How long would it take you to upgrade these servers now? You may decide the entire operation is unfeasible.

KVM on grid is a flexible, fast solution enabling dynamic management and allocation of virtual machines in large scale high-performance environments. It revolves around state of the art open-source virtualization, combined with distributed computing models. This allows near-real time deployment of systems on a mass scale, minimizing the overhead and complexity of the environment. It’s not cloud, it’s not batch, it’s “KVM on grid”!

Instance Types: Using oVirt as a Private Cloud Solution - Tomas Jelinek, Red Hat
An effective and flexible VM management which promotes self-service is a crucial part of any private cloud solution.

The VM centric management with templates present until oVirt 3.4 has limitations in mass editing of VM properties, fine grained permission management and integration with third party services such as Glance from OpenStack.
There is an ongoing effort of improving this situation with a big milestone achieved with the releasing of oVirt 3.5 containing the Instance Types feature implemented.

This talk will discuss the new Instance Types feature introduced in oVirt 3.5 and will explain the reasoning behind the specific decisions made with an emphasis to show how does it aim to elevate oVirt from data center virtualization solution to a private cloud solution.

Also the limitations of the current solution and the next steps targeted to oVirt 3.6 will be discussed.

Location-Aware Distributed Virtual Disk Storage For OpenStack - Keiichi Shima, IIJ Innovation Institute
We have proposed a redundant block disk interface for storing virtual machine (VM) disk images. The paper is available at http://member.wide.ad.jp/~shima/publications/20131209-ccsna-ukai.pdf. The key function of the interface is that an operator has full control over where to store disk images on which distributed storage nodes. This is important especially when a VM infrastructure is deployed over many different geographical locations. VMs are sometimes moved across hypervisors due to resource constraint or maintenance operations. It is a serious problem how effectively the virtual machines contact to their storage images when moving. By acquiring full control on a disk image migration decision, an operator can move related disk images to nearer location of the moving VMs. This presentation will show the design of the proposed system and the current status of OpenStack integration.

Tame the USB Gadgets Talkative Beast - Krzysztof Opasiak, Samsung
The new USB composite gadget ConfigFS interface allows user to compose an custom gadget form USB functions at runtime. Function logic may be placed not only in kernel modules but also in userspace using FunctionFS. Usage of legacy gadgets was reduced to one modprobe command. While new interface provides good flexibility, it might take as many as 20 commands to set up an gadget. This definitely requires userspace reaction which will tame this talkative beast.
First, this presentation will provide an overview of new USB interface features and show how to use them from command line. Then userspace response is given. Libusbg, C library for gadget management with its brand new functionality - gadget schemes will be presented. Final step is going to be introduction of gadgetd - open source daemon for convenient, system wide USB gadget and FunctionFS based services manager.

Tizen-Meta as Security and Connectivity Layers For Yocto Project - Dominig ar Foll, Intel
The Internet of Things (IoT) is growing fast and opens large opportunities to embedded Linux. Unfortunately traditional embedded Linux has been weak when it comes to security and complex connectivities enabling.
Tizen which has been developed as a Linux base OS for connected object (phone, TV, car) is on the other side very well equipped in that area.
We will start by explaining what is Tizen architecture and how it provides Security and Connectivity facilities on top of a base Linux.
We will then show how Yocto and Tizen-meta can be used to create embedded devices which benefit from several years of work done by the Tizen community.
In particular we will review :
- the mandatory access control enabling in an embedded device
- the enforcement of good behavior by applications
- resource access control
- connectivity layers
- HTML5 App enabling.
- multi user mode enabling.

Linux Kernel Tinification - Josh Triplett, Intel
Cell phones and routers hardly qualify as "embedded" anymore; new embedded systems (or the new Things we will have an Internet Of) push for ever smaller storage and memory requirements. Most people building systems that small assume that Linux will not work for them, and that they have to use a dedicated embedded OS or custom code from scratch.

This talk will show just how small Linux can get while remaining functional, what it'll take to push Linux an order of magnitude smaller in the future, and how kernel and systems developers can avoid regressions in memory or storage requirements.

Systematic Testing of Fault Handling Code in Linux Kernel - Alexey Khoroshilov, Russian Academy of Sciences
The talk presents a method to extend coverage of existing tests by systematic and targeted fault injection in Linux kernel. The method is developed within Linux File System Verification project that aims to provide an exhaustive test suite for Linux file system drivers.

The presented method of fault injection allows to systematically simulate faults dedicated to a file system driver under test (faults of memory allocation requests, bio layer, etc.). That means it does not introduce faults into requests coming from other modules and it implements systematic iteration of fault situations versus a prevailing random approach.

The talk presents results of experiments with the method, defines requirements to tests so they can be used with the method and discusses lessons learnt so far.

High Performance Storage with blk-mq and scsi-mq - Christoph Hellwig
This presentation gives an overview over the problems of the existing Linux storage stack to deal with low-latency and high IOPS devices, and explains how these are addressed for future Linux releases. Blk-mq provides a replacement for parts of the Linux block layer and allows drivers to support low-latency I/O, and a high number of I/O operations as well as scale better to large number of CPUs. SCSI is the most important enterprise block storage protocol, and thus enabling the SCSI layer to use blk-mq allows to take advantage of it for a wide range of commercially available storage hardware, especially high performance storage arrays. This presentation will explain the high-level details of the architecture of blk-mq and scsi-mq, show performance comparisons to the previous architecture and will show developers how to take advantage of the new capabilities.

Playing Nice With Patents: Navigating The Legal Landscape For Collaborative Development - Justin Colannino, Till Jaeger, JBB Rechtsanwaelte, Catherina Maracke, Keio University
Growing commercial competition between technology companies has created a new focus on obtaining and enforcing patent portfolios. In this environment, the community must understand the interplay of the patent system with free and open source software development. In particular, we should examine patent licensing mechanisms underlying community development to identify those that encourage collaboration instead of litigation. Looking ahead, project maintainers must find the right legal mechanisms to ensure continued community participation and stability. In this session, community lawyers Catharina Maracke, Till Jaeger, and Justin Colannino will walk participants through several patent licensing schemes currently in use by free and open source software projects, and will discuss improvements and modifications to further protect the community.

Advanced Linux Server-Side Threats: How They Work and What You Can do About Them - Olivier Bilodeau and Marc-Etienne M.Léveillé, ESET
Server-side malware evolved. Attackers were motivated by defacement or direct damage, using small-scale and targeted operations. Nowadays we are seeing an increase in organized crimeware campaigns leveraging compromised Linux servers for financial gain through website redirections infecting end-users and spam. Furthermore, malicious gangs base their operation's infrastructure on these same servers, making takedown or law enforcement intervention complex.

This presentation will cover the evolution of Linux malware and describe the Windigo threats affecting more than 25 000 servers. We will give in-depth technical details on the malware involved, show how it is deployed by the operators and how they are able to defeat current defensive technologies. More importantly, we will describe hands-on detection and incident response tips to quickly assess one's servers and help in the fight.
