Linux Kernel Network Stack Walkthrough

This presentation features a walk through the Linux kernel networking stack covering the essentials and recent developments a developer needs to know. Our starting point is the network card driver as it feeds a packet into the stack. We will follow the packet as it traverses through various subsystems such as packet filtering, routing, protocol stacks, and the socket layer. We will pause here and there to look into concepts such as segmentation offloading, TCP small queues, and low latency polling. We will cover APIs exposed by the kernel that go beyond use of write()/read() on sockets and will look into how they are implemented on the kernel side.

Speakers

Eclipse Platform Unleashed

Eclipse is most commonly known as Java IDE. However, it is a lot more than that. It can be used as a platform for Rich Client Applications as well as functionally extended via its plug-in architecture. Almost everything in Eclipse is implemented as an Eclipse plug-in in one way or another. These components provide a myriad of specialized functionality and Extension Points allowing the gifted developer to implement almost anything they've set their mind to.

In this hands-on lab some of the cool new features of Eclipse Kepler are demonstrated. Have you ever considered using Eclipse CDT + Linux Tools for C/C++ development? CDT + Linux Tools bring profiling and memory corruption detection support directly into your IDE. Are you a Java developer using Eclipse? How efficient are you browsing the code base you are working on day-to-day? Learn how to use Eclipse's core features in order to increase your productivity as a Java developer. Did you know that E4, the new face of Eclipse, allows you to make your Eclipse based application look the way you want it to look? Gone are the days where you could spot Eclipse based applications right away. With E4 and CSS you can achieve this by simply shipping your own CSS file along with your application.

This session also gives an introduction to developing an Eclipse Plug-in. In order to get the most out of this session, helpful tools for developing Eclipse plug-ins are introduced along the way.

Language: English
Audience: Java/C/C++ developers && anyone interested in Eclipse Plug-in development

Writing an internal DSL language in Scala

Have you ever wanted to write your own programming language? Why not to start with much simpler task - writing some domain specific language. Since the Scala programming language is a great fit for creating internal DSL, we will utilize its functional nature and implicit conversions, and together we will create a fluent API in form of a DSL.

Scala noob? No worries! No previous Scala experience is needed, all the techniques will be explained during the workshop. It’ll be piece of cake if you know any modern programming language.

Re-thinking Web App Development with Web Components standard

Web Components is an emerging umbrella of standards that fundamentally changes the way we compose our web applications. Web Components abstract away the complexity introduced when using low-level building blocks such as HTML, CSS and JavaScript.

This complexity is usually handled on the level of web frameworks, where we can perceive few phenomenons: web frameworks usually

it’s own way of how to work with low-level APIs,
maintains custom UI widget suites,
lock us in a particular solution.

What about inventing some common denominator that could frameworks and app developers built upon?

Web Components are essentially a set of improvements that are being added to the web platform: HTML Imports, Shadow DOM, <template>, custom elements, object observers, DOM mutation observers, MDV, new CSS primitives. All of these APIs are on their way to becoming standards. But can we leverage them already?

Thanks to polyfill libraries like Polymer we can leverage those new APIs right away!

Thanks to Web Components, the web will get a new common denominator which kills fragmentation and encourages reuse and portability of user interfaces.

OSTree: A middle ground between packages and images

OSTree allows clients to atomically upgrade and switch between multiple versioned filesystem trees. It was designed from the start to complement package systems like RPM and dpkg.

It offers a middle ground between the extreme flexibility of package systems, and the singular OS vision of operating systems such as ChromeOS.

Being less flexible allows OSTree to (in some scenarios) be much faster and more reliable than packages, which is an important component of doing continuous integration and deployment. For example, this talk will discuss releasing Fedora 100 times a day or more, rather than just "nightly".

Thermostat - Show YOUR Java Application's Performance Metrics

It is important to understand your Java application's behavior at runtime. This becomes business critical if your application behaves poorly when deployed in production. Having data for analyzing your Java application's misbehavior can be crucial. Thermostat helps with that and provides developers and admins with a framework for Java application monitoring and instrumentation.

Thermostat comes with recording and visualization capabilities for your Java application. It also allows for decoupling of metric recording and its analysis. What's more, Thermostat supports remote monitoring and instrumentation of the system which is hosting your Java application while keeping the extra overhead minimal. In short, it can provide an inside perspective of what's happening inside your OpenJDK JVM while it's executing your application.

In this session we'll show some of Thermostat's out-of-the-box-features and we will conclude with a hands-on workshop developing a simple Thermostat plug-in. This plug-in will perform certain actions based on events happening at runtime in a remote Java application. Attendants will be guided through the process of creating this plug-in and will furthermore see how easy it is to extend Thermostat in order for it to do what YOU need it to perform.

Language: English
Audience: Java developers/Sysadmins

JSF 2.2 deep dive with RichFaces 5

JavaServer Faces (JSF) is the portion of the Java EE specification that deals with the rendering of web UIs. A server-side rendering framework, JSF is component centric and nicely encapsulates both visual and non-visual UI elements and provides a health component marketplace.

The JSF specification as recently undergone a minor release increment with the release of JSF 2.2. While not the revolution seen with the release of the 2.0 specification, JSF 2.2 does include some new and sought-after features. We’ll cover these new features discussing: View Actions, Faces Flows, HTML 5 support, improved CDI integration, the FileUpload component, Resource library contract, stateless views, and the new window ID.

Taking a use-case based approach we’ll see how this laundry list of new features will affect your application development. Finally we’ll look at how the RichFaces component library is leveraging these new capabilities in the upcoming RichFaces 5 release.

Why use a SAT solver for package management?

The DNF project is scheduled to become the new YUM in Fedora 22. The underlying dependency solver, the libsolv library, uses a satisfiability (SAT) solver to do its work.

This talk will give you an understanding of how SAT based dependency solving works and what its advantages compared to traditional approaches are. For example, most solvers will just abort with an error message if a dependency problem has no solution, whereas a SAT based solver allows the automatic generation of solution proposals.

This gets even more important when build systems like COPR or OBS gain popularity, as the chances of dependency problems increase with the number of uncoordinated repositories.

Another advantage of using a SAT solver is its speed. We will show solver results and timings for some real life examples and do a comparison between YUM and DNF.

GNOME Software

In this talk I will present GNOME Software, the application installer for GNOME that first appeared as a technical preview in Fedora 20. I will discuss the feature set of the application, the motivations for building something new, and also explain where we are headed for Fedora 21 and more. I'll quickly explain which technologies and standards that we've leveraged and the things we've deliberately ignored. From Fedora 20, this will be the tool that people will use to install applications, codecs and fonts, but I'll also mention other distributions and the challenges they and us face. I'll end with a plea for help, and explain how both users and developers can help make the application even more awesome. They'll be ample time for questions at the end too.

Save your time with autotest

This course begins with Autotest* introduction (web UI, server, standalone instance). Then we will show you on a set of examples various framework features, which simplifies and speedups your test development.

The biggest advantage of Autotest is a very steep learning curve. Simple "Hello world" test which spawns VM and executes "echo Hello world" looks like this using Autotest Virt-test:
echo Hello world

Of course we will tweak the course according to your needs and skills. We are prepared to spawn tenths of machines, attach thousands of disks and blow your mind with machines migrating across multiple physical machines all thanks to the Autotest framework.

JGroups

JGroups is a messaging framework which allows developers to create reliable messaging (one-to-one or one-to-many) applications where reliability is a deployment issue, and does not have to be implemented by the application developer.
The most powerful feature of JGroups is its flexible protocol stack, which allows developers to adapt it to exactly match their application requirements and network characteristics.
The benefit of this is that you only pay for what you use. By mixing and matching protocols, various differing application requirements can be satisfied.

Cockpit: the Server UI

It's no secret that Linux runs much of the Internet, as well as all sorts of infrastructure and servers. In large part that's due to our community, and the great projects we've worked on together.

Where we've fallen short, is making these technologies accessible. Non-expert administrators often don't know where to start to make use of the powerful stuff we've put together. This ends up preventing further use of Linux.

Enter Cockpit. It aims to be a lightweight, installed out of the box, interface for performing basic monitoring, configuration, and installation on Linux servers.

Perfect for bringing new sysadmins to Linux, but we also aim to make repetitive tasks work well for experts, and respect and integrate well with other configuration tools out there, including the terminal.

In the talk we'll talk about why the Cockpit project was started, how Cockpit works, including its networking and multi-server aspects, and how you can get involved, try it out. We'll have a demo to show you were things are at, and some discussion of where we're headed.

Now with a very strong enterprise focus, it gained additional security properties with strong encryption, signatures and the ability to anonymize log files. Also, the upcoming version 8 provides strong new features and scalability and performance enhancements.This talk will describe the new features, why they were introduced and how they are implemented. Most importantly, the new v8 engine and output module interface will be described. The interface has totally been revamped and plugin authors need to abide to the new interface in order to be compatible with v8. We also describe why this hard requirement was placed on plugins ... and how easy it usually is to convert v7 plugins.

Anatomy of kdbus

In contrast to later OS designs Unix/Linux since its beginning has not provided a standardized, high-level IPC system as part of its system APIs. It has provided various primitives such as AF_UNIX sockets, FIFOs, and various forms of shared memory and synchronization facilities, but it always lacked an established mechanisms for secure, introspectable, standardized local RPC with multicasting signalling. Various attempts have been made to build such a system on top of the available primitives, the most important and successful project being D-Bus. D-Bus brought standardization and introspectability however being designed for exchanging control messages only, brings serious performance issues when it is used to deliver payload.

In this talk we'll discuss "kdbus", our attempt to move D-Bus into the kernel layer, to make it truly universal, and how it is integrated into systemd and its APIs. kdbus brings scalabale, secure, high performance IPC on the kernel level, while staying compatible with classic D-Bus in most ways. From the beginning it has been designed to provide single-copy and zero-copy communication, and namespacing and sandboxing has been designed into it from the beginning.

When designing "kdbus" we took a lot of inspiration from IPC systems in the Operating Systems, including most importantly Android Binder, Mach Ports, Solaris Doors, and QNX IPC, which we will cover in this talk too.

Vulnerability management and security compliance by SCAP

Security compliance is conformance to security requirements that are usually defined either by industry standards (USGCB, DISA STIG, PCI DSS) or custom policies specified by an organization itself. Unfortunately reaching the compliance is not that easy. Some of the issues users may run into are:
* lack of a security guidances, checklists, and associated validation mechanisms
* lack of high quality (as in certified) scanners - auditing tools
* difficulties with security profiles customization
* missing remediation capability in current standards (remediation allow users to alter system configuration in order to put system into compliance)
* integration with system management solutions that can facilitate monitoring and reporting

In this talk we will introduce various components (scanner, data, installer and systems management solution) that comes into play when we deal with these kind of challenges. We will also describe work-flow these components have established and we will show you where and how you can start contributing in order to make the security compliance more suitable for your needs. Our main focus will be on contribution to the compliance requirements repository which is hosted by the scap-security-guide project.

Mutation testing: how good your tests really are?

Standard code coverage analysis provides insight into execution paths exercised by a testing scheme. Mutation testing takes this notion a step further and offers a deep down investigation (through code modification or removal) of the impact each line of production code makes on the whole test. This approach has been known for over 30 years circling mainly within academic communities and only recently has it been rediscovered and introduced to the benefit of commercial solutions. Mutation testing technique which focuses on partitioning the code on per line basis with regards to influence on the logic put under test provides actual (as opposed to artificial and synthetic) view on tests quality.

The presentation will provide solutions and answers to the following:

What is mutation testing?
Why use it?
Limitations and drawbacks
Why only now does it start to get traction?
How to prepare your project for mutation testing?
Is there a case for it in the enterprise?

This presentation is meant for software development-involved individuals who want to learn more about mutation testing, what advantages over traditional coverage scheme it offers and how to apply the idea to their existing codebase. Although not required, some knowledge on test automation and coverage would be beneficial to the attendee.

The introduction to mutation testing will be language agnostic. Presented tools can be used only with Java code.

Thin provisioning in the KVM virtualization stack - how we got there

QEMU, the virtual machine monitor typically used with KVM, has long supported thin provisioning through both sparse raw files and the qcow2 image format. However, for thin provisioning to help both virtual machine users and host administrators, it must be supported throughout the whole virtualization stack: the guest (userspace and kernel), the host (QEMU, management interface, kernel), the storage itself. This talk will show how we implemented thin provisioning in all these layers and how the results benefit our users.

USB reverse engineering workshop

Even though most USB devices will just work with Linux now a days, every now and then there is still a USB device which does not work and needs to have its USB protocol reverse-engineered. Or which needs some reverse engineering of ie custom HID reports to be able to fully use all its functionality (think usb keyboards/mice/joysticks with special functions such as an lcd display).

This workshop will teach participants the basics of reverse engineer USB protocols, which is the first step to adding Linux support for such devices.

Preparation:
Participants should have:
1) An USB- device they want to reverse engineer the USB-protocol for
2) A laptop with a recent Linux on it, as well as a windows vm on top of Linux to run the software for said USB device

Aspect-oriented User Interface design

Contemporary user interface (UI) design tangles multiple different interests together, which results in increased efforts of its development and maintenance. In addition, information captured in backend parts of the system is being restated in the UI part, which negatively impacts maintenance and may cause its inconsistency. In this talk we present aspect-driven approach that suggests separating various UI interests and concerns, and enables their reuse among the system. This runtime approach allows us to reduce development and maintenance efforts, mitigate inconsistency errors, and to build low effort adaptive UIs. Our open-source framework is deployed in production at Java EE 6 application at ACM-ICPC system. We present benefits of this concept, experiences received from its production use and impact on system maintenance.

fedmsg - Fedora Infrastructure's realtime message bus

Description
-----------

In the Fedora Infrastructure team, we developed a realtime messaging layer on top of 0MQ to send and receive messages to and from our many and varied services. Debian Infrastructure has adopted it as well laying the basis for a multi-distro realtime message bus.

In this presentation, I'll give an overview of fedmsg -- the Federated Message Bus -- what it is, how it works, and why some design decisions were made the way they were. The second half will cover projects that integrate with fedmsg.

Abstract
--------

- What fedmsg is good for

- A way to keep your finger on the pulse of open source development
- A source of community metrics over time
- A platform for building out reactive realtime infrastructure

- What is Fedora Infrastructure? "How a Linux Distribution gets made"
- Overview of our topology -- what services are tied in
- Design decisions necessitated by an Open Infrastructure

- Signed, but unencrypted
- No central broker
- Public zmq.PUB socket

- CLI tools and API examples
- Applications built against fedmsg

- End user notifications for everyone - Desktop/Android/IRC
- Push to test/qa infrastructure
- Push notifications to mirrors
- Sync apprentice and packager credentials
- Visualizations - Faking git logs for "gource"
- Reports - fedora-news, this-week-in-fedora, & owner-change-tool
- Fedora Badges for distro contributors

- Debian adoption - Imagine a multi-distro realtime development pony

Outline
-------

- What fedmsg is good for

- A way to keep your finger on the pulse of open source development
- A source of community metrics over time
- A platform for building out reactive realtime infrastructure

- What is Fedora Infrastructure? "How a Linux Distribution gets made"

- What do packagers do?
- What does release engineering do?
- How do we communicate, make decisions, govern ourselves?
- Design and development.
- Testing, QA, bug reporting.
- All the good things in life.

- Overview of our topology -- what services are tied in

- [just talk about this diagram](http://threebean.org/presentations/fedmsg-flock13/images/fedmsg-flock13-img/topology.png)

- Design decisions necessitated by an Open Infrastructure

- We have an open infrastructure. You can show up at our weekly IRC meeting and get "fi-apprentice" rights to log in to machines.
- Signed, but unencrypted. Anyone can read, anyone can write. Only some messages are trusted. Key here is that anyone can debug at any point in our infrastructure.
- No central broker. Datacenters are donated and distributed. Things can go down. fedmsg designed to not bring *anything* down with it.
- Public zmq.PUB socket. The world can read at ``tcp://hub.fedoraproject.org:9940`` -- point a ``zmq.SUB`` socket at it with ``recv_multipart``.

- CLI tools and API examples

- CLI: ``echo "hello world" | fedmsg-logger``
- CLI: ``fedmsg-tail --really-pretty``
- API: ``fedmsg.publish(...)``
- API: ``fedmsg.tail_messages(...)``

- Applications built against fedmsg

- fedmsg-notifications. -- Problem: all of our applications carry their own email code. With that comes further baggage and maintenance.
With fedmsg notifications for interesting infrastructure events, we can put all that code in one place where it can be more easily maintained.
Benefit to the end-user: manage notification preferences in one place instead of per-app.
Opens up notifications to different contexts: Email? IRC privmsg? Android? RSS?

- Push to test/qa infrastructure.
When new packages are built, we can instantly run depchain analysis tests. This is was done previously with cronjobs.
When new composes are complete, we can fire off jobs in beaker to make sure install and integration tests pass. This was done previously by hand.

- Push notifications to mirrors
Over 200 mirrors right now. They have cronjobs that poll with rsync, we can use ``fedmsg-trigger`` to fire off rsync only when the compose notification is published.

- Sync apprentice and packager credentials
Ugly cronjobs exist that run that sync shell groups to machines from the Fedora Account System. With ``fedmsg-trigger``, we fire off an ansible playbook to sync creds when group-membership-change messages are published.
Same goes for package ownership and ACL changes. People had to wait up to an hour for their creds to propagate.

- Visualizations - Faking git logs for "gource".
Run "fedmsg-tail --gource | gource -i 0 --log-format custom -" to get the realtime version of [this](http://threebean.org/so-i-turned-the-fedmsg-data-into-a-git-log-and.webm).
Its the best office dashboard ever.

- Reports - fedora-news, this-week-in-fedora, owner-change-tool, & release engineering dashboard.
HTML5 dashboards that query the history of fedmsg to make useful reports.

https://lists.fedoraproject.org/pipermail/infrastructure/2013-June/013070.html
https://apps.stg.fedoraproject.org/releng-dash/

- Fedora Badges for distro contributors
https://badges.fedoraproject.org
Backends listens to the bus and wakes up in response to new events.
Compares messages against a series of 100 or so rules defined in YAML. If a
contributor matches some criteria, then they are awarded a badge (achievement
unlocked!)
Fun fact -- this is hooked into Mozilla's Open Badges Infrastructure (OBI). https://openbadges.org/

- Debian adoption - Imagine a multi-distro realtime development pony

- This is amazing. Their bus is still coming up but they have a ton of message types already passing over it.
- They too have a publicly subscribable endpoint. Your end user machine can subscribe to *both* the Fedora and the Debian buses.
- Imagine this scenario: a security bug gets filed in Debian. A Fedora daemon listens to their bus and automatically files the same bug on our tracker against the same package (perhaps it is smart and checks for dupes first).
- A new package update is marked as a security fix in Fedora, a debian daemon listens and tries to check if the same patch is applied there. If not, it emails the maintainer to find out whats up.
- We just started talking about a Holy Grail - integrating compatible semantic DOAP and FOAF information with all messages so we can easily correlate activity between the distributions.
- Can we provide a service to upstreams? Aim your github service hook at some bucket service. When you tag a new release, it notifies the upstream-bucket, the upstream-bucket notifies anyone who wants to know (Fedora, Debian, & friends).

Automation in the Fedora land

Tools and technologies to automate our work as upstreams or packagers.

The Fedora community is composed of a large number of diverse profiles. From
ambassadors, to translators, to packagers and upstreams developers, we are all
doing our work and as a result for 10 years we have been releasing a new Fedora
(almost) every 6 months.

However, there are a number of occasions where this work could be made simpler,
more accessible, more automatic.

This presentation will focus on developpers, sysadmins and packagers and present
them with tools and technologies available in Fedora that make their life simpler.
From Jenkins to ansible, from Copr to FMN or the *2spec tools from the existing
solutions to some crazy ideas (Debian and Fedora integrated notifications, package
review application...), there are many ways to make your life simpler.
Do you know them all?

Why 3D printing software workflow sucks

Fedora 19 brought a new "feature" - it was the first distribution that packaged all free 3D printing tools and apps available. That's great, no doubt. But the current 3D printing workflow form the software perspective suck. Users have to run dozens of apps to print a model.

In this talk, I'll introduce the current workflow and explain why it sucks. I'll also show how it could be done and bring up some ideas how to implement it. Several project that aim the same thing will be presented. The idea here is to integrate 3D printing to the Linux desktop and make 3D printing as easy as hitting Ctlr+P - let's make 3D printing a real feature.
