What is kubernetes?
Feedback
Kubernetes is a new docker container orchestration project being led by Google and Red Hat. For many years Google has run their datacenter, clustering, and orchestration capabilitie with the equivalent of what we all now call containers. As the docker container ecosystem grew Google realized that they could bring their knowledge managing containers at the largest scales, Red Hat could bring their knowledge of datacenter operations across many organizations, and working together in the open source community we could create a better container management solution than anyone alone.

This talk will cover what Kubernetes is, what it hopes to one day accomplish, and what choices it forces on application authors. It will cover the patterns which Kubernetes simplifies and cover some concepts that are just not possible when using Kubernetes.

Architecting Large Enterprise Java Projects
Feedback
In the past I've been building component oriented applications with what I had at hand. Mostly driven by the features available in the Java EE standard to be "portable" and easy to use. Looking back this has been a perfect fit for many customers and applications. With an increasing demand for highly integrated applications which use already available services and processes from all over the place (departmental, central or even cloud services) this approach starts to feel more and more outdated. And this feel does not come from a technology perspective but from all the requirements around it. Having this in mind this post is the starting point of a series of how-to's and short tutorials which aim to showcase some more diverse ways of building (Java EE) applications that fit better into today's requirements and landscapes.

Hardware switches - the opensource approach
Feedback
Imagine buying off the shelf switch hardware, install Fedora (or any other distribution) and configure it using standard linux tools. This is not possible at the moment primarily because of lack of unified and consistent platforms and driver interfaces. We are working to change that.

The current state of support for switch chips in Linux is not good. Each vendor provides userspace binary sdk blob that only works with their chips. Each of this blobs has proprietary APIs. To get switch chips properly supported there's need to introduce a new infrastructure directly into Linux kernel and to work with vendors to adopt it.

This talk presents the current effort to unify and uphold the Linux networking model across the spectrum of devices which is necessary to make Linux the cornerstone of industrial grade networking. The scope of this talk covers state of art with current implementation of standard commodity switches such as top of rack switches, small home gateway device as well as SR-IOV NIC embedded switches.

A device model and driver infrastructure will be presented for accelerating the Linux bridge, Linux router, accelerated host virtual switches and flow level offloads when supported by the hardware underneath.

Foreman & Katello: automating the infrastructure thing

Ok, so you've got your favorite virtualization platform up and running in your infrastructure. Perhaps you've even connected it up to the cloud. And wait… what's in this room with a sign on the door saying "Beware of The Leopard"? Bare-metal machines? Aaah, so the VMs are not that virtual after all. Luckily, we have the Docker now that will solve all our problems… or will it? [Mention the Docker in your talk: ✓]

Let's leave unicorns at home for a while and look at various needs you have (or will probably have sooner or later) in your infrastructure and how you can employ Foreman (http://www.theforeman.org) and Katello (http://www.katello.org) to help you with them.

OpenSCAD: Code your 3D models not only for 3D printing
Feedback
3D printing is a popular topic among geeks. One of the general problem we face is: Where to get a 3D model to print? Most of us are good coders, but lousy designers. Let's face it. Trying to produce some content in Blender drives me crazy and it usually ends up as crap. That's where OpenSCAD comes in handy. Quote from the OpenSCAD website [1]:

"OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designs that are defined by configurable parameters."

In this workshop I'll teach you how to use OpenSCAD and how to create useful parametric 3D models designed mostly for 3D printing.

Come with OpenSCAD pre-installed. On Fedora, that means installing the
openscad package (openscad-MCAD can be installed as well). On other
platforms, see http://www.openscad.org/downloads.html - also note that
we will use OpenSCAD 2014.03. Newer dev snapshot is also fine, but
nothing older (e.g. Ubuntu package is old).

Is code in your project sane enough?
Feedback
This demo session will show how we can easily check the sanity of code in our project. There is a tool named csmock, which takes an SRPM (or upstream tarball) and produces a list of possible defects in its code. Besides plug-ins for C/C++ analyzers (GCC, Clang, Cppcheck), csmock now comes with experimental plug-ins for static analysis of python and shell scripts. We will also discuss how we can efficiently process the results of these tools and how to integrate them into our workflow.

Reliable code construction using cmockery2
Feedback
Developers use unit tests during development to maintain a high level of quality in their applications. Most of these developers create unit tests for applications written in languages like C++, Python, Ruby, Java, and Go. While developers writing applications in C language are likely not aware of this development model. The lab will concentrate on the benefits of programming-by-contract, unit test, and mocking methodologies using cmockery2, an extremely powerful and easy to use unit test framework for C language.

Transactions Returning to NoSQL
Feedback
Over the last few years, we have seen the rise of NoSQL and big data. The CAP theorem is often cited as a reason for many of the architectural decisions used in the development of NoSQL, and one consequence is that most implementations do not support transactions. This lack of transactions offers benefits for some applications, but it has certain downsides, particularly in terms of fault tolerance and integrating with existing Java EE applications. As a result, the last year or so has seen many NoSQL implementations adopt transactions in one way or another. This session examines this trend back to adopting transactions, why it is happening, and what it means for the future.

Using OS-level identity, authentication, and access control for Web applications
Feedback
Authentication and access control are well-supported on the operating system level by projects like FreeIPA and sssd, including integration with Active Directory. Users can then authenticate once, and access machines within their organization without being prompted for password again.

But how about web applications?

In this talk we will look at Apache modules that allow the single-sign on with central access control and identity services to be used for web application as well, building on top of the same bits that are already proven to work well on the OS-level, rather than reimplementing all the parts again. Multiple web projects and products have already been enhanced to take advantage of this setup so demo is more than likely.

Data Plane Acceleration - Receiving Packets at the Speed of Light
Feedback
As network speeds continue to increase from 10Gb/s, to 40Gb/s, and very soon to 100Gb/s the rate at which packets can arrive increases, and as a result the amount of time to process packets decreases to as little as 6.7ns per packet at 100Gb/s. When something as simple as a memory barrier can cause stalls of 7ns or more strategies must be devised to mitigate such issues so that we can process as many packets per core as possible. This talk will go over some of the mitigation strategies being employed to reduce these costs and bring the kernel networking stack down to receive processing times sufficient to allow for wire rate networking at minimal packet sizes.

Cleaning up the mess of cloud networking
Feedback
The network configuration requirements of computers powering cloud infrastructure are very different to the traditional way of how the network is set up. The existing Linux kernel features are often not enough for this task and projects like OpenStack use the existing features to their very limits, sometimes even over them. New projects have been started to deal with this; a most prominent example is Open vSwitch. However, despite the quick pace of development, there is still lack of needed features on the kernel part. This leads to creative usage of combinations of the currently offered kernel features, leading to very complex undebuggable configurations. If you log in to such machine, you find tens of virtual interfaces and name spaces with strange non-obvious relationships between them.

The talk will present a few possible ways to get out of this. A new tool, plotnetcfg, that allows easier overview of the network relationship will be shown. The workarounds that are deployed by cloud platforms (as seen in the wild) will be explained and corresponding missing features in the kernel will be identified. How to implement them is in many cases an open problem; some possible solutions will be discussed. Interestingly, Open vSwitch may not be an answer for everything.

Data Processing in the OpenStack world
Feedback
While the core OpenStack components provide good tools to manage the infrastructure, handling more complex scenarios, like for example the set of machines required by Data Processing toolkits (Hadoop) requires a bit of manual intervention.
Sahara, a recently-integrated component of the OpenStack project, can manage such kind of resources by leveraging the existing OpenStack components (Nova for instances, Glance for images, Swift for data storaga, Heat for orchestration, etc). Initially targeted to support Hadoop distributions, thank to its modular plugin-based architecture Sahara gained support for other processing model, like Spark and Storm.

The goal of the presentation is to introduce the concepts behind Sahara, its integration with the rest of OpenStack ecosystem and a brief demo of its functionalities.

Provision and manage Docker containers with Foreman
Feedback
Deploying containers, images with Docker is becoming a big trend. However, large installations of containerized applications are still few and far between, and solutions are either proprietary or they force you to use their own cloud.

We believe Foreman can fill this space by providing a central space to provision and manage your containers and your network, as we already do with your data center. This provides a great framework for mixed environments where physical machines, vms, and containers are all used in conjunction.

Monitoring, deploying, and everything else is possible to do through the web UI or an API, and it's open source, so if you miss any feature, feel free to add it!

A proposal for a container-based, highly-portable development environment
Feedback
Most developers struggle with "maintaining" their development environment. For me that includes:
* ensuring my "communications" are not interrupted by the addition of new software
* backup of critical information
* support for easy portability from one computer to another (or through an OS upgrade)
* transparent movement from offline to online access
* rollback support for changes to the environment
* forking of the environment for new/different languages and projects I am definitely one of those people and have found various techniques over the years to attempt to solve these problems but none of them quite do it. Unfortunately, I think the needs of developers are somewhat unique and most tools and techniques are targeted at "general users" or "servers" whereas developers are somewhere between the two.

As a result, I have been working with a few others on a proposal and some early software to try to meet these needs. We have been wrapping the proposal around containers because of their "out of the box" universality, portability, snapshotting, and forking.

I would like to present where we are, what we plan, and invite feedback.

JBoss Windup – Don't be afraid of migrations
Feedback
Windup is a tool to simplify Java application migrations. The tool analyzes application artifacts (such as Java code, JSPs and XML) and produces an HTML report highlighting areas that require changes.

Windup is, simply said, an executor of the rules that are registered. The project is packed with the main bundle of rules, however you can easily register your own, newly created rules. In the presentation we will discover how the windup works underneath and how you can easily provide your own rules.

shellshock!

In September 2014, internet was rocked by a widespread security flaw called shellshock. It seemed to affect everything from web servers serving CGI, to dhcpclient etc, and even some satellite television settop boxes.

The presenter was responsible for ensuring Red Hat / Fedora and its customers/users were protected against this. Red Hat not only pioneered the patch which was used, but also provided guidance to other distros/upstream.

This presentation is a brief look at how these kind of security issues affect open source, provide a brief time line of what happened and why and how developers can often help ease out the pain :)

Virtualization: KVM: Has ARM done it better?
Feedback
This talk is a twofer (a two for one deal). We'll describe how KVM works, but not just one way, two! While stepping through the process of booting a simple guest, we'll look at what's going on in both the implementation of KVM for AArch64 (ARM's 64-bit architecture) and in the implementation for x86_64/VMX (Intel's 64-bit architecture). As the two KVM implementations are the products of their respective architecture's virtualization extension designs, we'll gain some insights into what design decisions appear to be "better", at least from a developer's point of view.

After a brief talk on the current state of weak and rich dependencies in RPM and their support in Fedora I want to collect possible use cases and discuss how these new dependencies can be used in Fedora and future RHEL versions. Ideally we would be able to come up with proposals for new packaging policies that can discussed and further refined publicly after the workshop.

I am especially interested to hear from representatives of special interest groups that feel that the classic dependencies do not fulfill all their needs or hope the new dependency model may help their cause.

Cockpit is the modern Server UI for Linux. It's built to be very light, thin, secure, interactive and well integrated with the server and its services.

Besides being a discoverable and polished UI out of the box, Cockpit has a powerful architecture that allows writing you to write server user interfaces for your projects. We'll demo how easy it is to prototype a user interface and interact with your server tool or service.

When you come away from this talk you'll have a better idea of how Cockpit is put together: how it communicates with your server, authenticates users, connects out to multiple servers, is embeddable in other projects, and what makes it different from server control panels and configuration management software.

Improvements in Nested Virtualization
Feedback
Nested Virtualization is an interesting feature to allow guest hypervisors to run their own guests utilizing hardware provided virtualization extensions. Much of the work for Intel processors is based on the Turtles research project at IBM.

This talk is intended as an introduction to the feature and how it works in its current form. We will briefly discuss various performance improving features that have been introduced such as nested EPT, Shadow VMCS and APIC Virtualization for Intel Processors. We will also discuss some work-in-progress features that could enhance functionality and improve performance.

This discussion is expected to help users gain a better understanding of the topic so as to ease troubleshooting, experiment with new and interesting use-cases and get a better understanding of currently available processor features to make Nested Virtualization better.

So you created this fantastic development tool for CoolFrameWork version 1.3.5. But as could be expected the CoolFrameWork developers recently came up with 2.0 and they broke quite a lot of API… To make matters worse, some users of your tool are dying to see support for the latest and greatest version while others still swear by old and stable.

Ubiquitous System Analysis with Performance Co-Pilot
Feedback
Performance Co-Pilot is a highly adaptable and established toolkit for those interested in examining the details of system performance. Designed from the ground up to compliment existing system monitoring, PCP is gentle in its approach as your statistics gathering mechanism. Likewise, PCP developers understand; what's most important for the sysadmin/end-user to monitor, may not be known, or even available to the upstream community. Hence, the following mantra is central to the PCP architecture: 'If it is important for monitoring system performance, and you can measure it, you can easily integrate it into the PCP framework'. This presentation will go over the basics of the toolkit, recent developments, how the developments fit within PCP's overall architecture, as well as some examples.

DNSSEC deployment from server and client side
Feedback
DNSSEC has been here for some time. But what it means to deploy it on the server? What is needed to keep your domain secured? There are a lot of manual and semi-automated tasks administrators need to do. This is where FreeIPA steps in and makes the deployment and maintenance of DNSSEC signed zone easy as few clicks in Web UI. Once you deployed DNSSEC on the server side, there is still some work to have your clients secured, too. Especially when using public hot-spots and networks, you should use secured DNS to eliminate man-in-the-middle attacks.

In the lab we will briefly explain how DNSSEC works. Afterwards we will deploy a signed zone using only BIND and also BIND + FreeIPA combination. We will show how FreeIPA can ease your pain with DNSSEC deployment. In the end we will try out the DNSSEC from client side using dnssec-trigger and unbound server, to keep you secured at all times.

News from perf land: probe, trace and scripting
Feedback
The Linux 'perf' tools continuously grows in scope as an observability toolchest, with more and more features being added.

In this talk the 'probe' and 'trace' tools will be showcased: the first allows adding dynamic probes in arbitrary points in the kernel and in userspace libraries and programs, collecting global and local variables, as well as callchains, that can then be used in conjunction with the other perf tools: record, top, trace, script, etc.

The later, trace, started as a super strace, one that allows stracing not just threads, but other targets such as the whole system, sets of CPUs, etc, in addition to threads. It also has a much lower overhead as it doesn't use the ptrace syscall. Support for tracing page faults and other events, as well as provide callchains leading to a syscall and other traced events are being planned and may even be ready by devconf'15 time!

An example of integration among perf tools, using 'probe' to allow capturing syscall arguments for pretty printing in 'trace', will be described, showcasing 'wannabe tracepoints', dynamic probes that may end up becoming real tracepoints.

Live Migration of QEMU/KVM Virtual Machines
Feedback
Live migrating vitual machines is an interesting ongoing area for virtualization: guests keep getting bigger (more vcpus, more vram), and demands on the uptime for guests keep getting stricter (so no long pauses between a VM migrating from one host to another).

This session will go through the simple design from the early days of QEMU/KVM live migration, how it has been tweaked to where it is now, and where we're going in the future. It will discuss how live migration actually works, the constraints within which it all has to work, and how the design keeps needing new thought to cover the latest requirements.

The discussion will cover known unknowns, i.e TODO items, for interested people to step up.

Each project is unique in its own way. It becomes difficult at times to follow any set rules when choosing tools/technology for testing; Instead we tend to keep few key points in mind while making such a choice.

Brief overview of the testing pyramid will help you slice your tests. I shall help you in finding out the tools/technologies you can choose to test backend, frontend, API, et al. I will be covering some of the key comparisons in tools like Selenium, Capybara, Watir from my personal experiences. Also, how BDD/BDT(using Cucumber) gives you an edge will be covered.

Integrating oVirt and Foreman to Empower your Data-Center
Feedback
In this session Yaniv will give introduction about the oVirt and Foreman projects. The session will focus about advanced and enhanced integration between those products in order to ease deployment of Host to an Hypervisors and provision VMs in a Virtualized environment.

Yaniv will describe how oVirt leverages Foreman functionality to provision bare-metal hosts or add existing ones as oVirt hypervisors. How we plan to extend that in order to provisioning VMs, configure existing hypervisors with repositories and advanced abilities and a lot more.

The talk aims anyone who interested in managing a Virtualized Data-Center using high-end open source technologies. Attendees can expect to get an introduction to oVirt and Foreman, and how they can use the two in order to build and deploy their Data-Center easily, while empowering the hardware they use.

Security Development Lifecycle in Open Source
Feedback
Original Security Development Lifecycle (SDL) has been developed in closed-source environment for software companies. Open Source development challenges many assumptions of SDL which is, as such, unsuitable in many usecases.

This presentation will talk about security in Open Source development throughout whole lifecycle, focusing on:
* security training materials and their availability to Open Source developers
* specifics of auditing and effectiveness of various forms and approaches (formal audit, hackathons, fuzzing, security testing)
* vulnerability research and development of mitigations and countermeasures

Automation of complex test scenarios via Arquillian Spacelift
Feedback
Using an application is easy. Testing it should be easy as well. However, testing scenario has external dependencies that differ on various platforms, take long time to setup and often test scenario itself does not provide enough flexibility and re-usability.

In this session, you will learn from our failures. You’ll see how Arquillian Spacelift helps you to bring tools you need for the test execution and lets you to define complex test scenarios that can be easily executed in CI and reproduced locally with zero setup required on a local machine and why we consider this approach superior to our previous attempts. You will also have a chance to see a live demo for mobile application test. And you would be able to reproduce the test on your machine!

Do not spend time with configuration any more, skip right to writing test scenarios that run from both CI and local machines out of the box.

The Best Test Data is Random Test Data (introduction to property based testing)
Feedback
An introduction to property-based testing, explaining its purpose and benefits, and demonstrating its use.

Testing accounts for a large portion of the cost of software development. Tools to automate testing allow for more thorough testing in less time. Property-based testing provides ways to
define expected properties of functions under test and mechanisms to automatically check whether those properties hold in a large number of cases - or whether a property can be falsified.

Concepts will be demonstrated primarily in Haskell, using the QuickCheck library. Property-based testing is available in most languages, so options for Python and Java will also be examined. The talk will conclude with a discussion of the limitations of
property-based testing, and alternative approaches.

The new oVirt Extension API - Taking AAA (Authentication Authorization Accounting) to the next level
Feedback
Prior to oVirt 3.5, authentication and authorization was implemented as
monolithic module, logic and schema was hard-coded, Kerberos was used for
authentication to LDAP server. It was very hard to support and it didn't contain
requested features like SSO or proper multi-domain setup.

In this session we will take a look at new extension API introduced in oVirt 3.5.
This API is designed to be stable (easy to extend without breaking backward
compatibility), simple (it's invoke based) and yet flexible (it allows extension
to extension communication and allows to write extensions in other languages
than Java like Javascript or JPython).

We will also take a look at the AAA (authentication, authorization, accounting)
extensions which leverages this API. Those extensions included in oVirt 3.5
allow to use generic LDAP or database for authentication and authorization or
allow SSO for UI and API part of oVirt.

Effective Beaker
Feedback
Do you run automated tests for your software, or do you wish you could? Do you need to test on multiple Linux distros or multiple hardware platforms (including those pesky non-x86 architectures you won't find in the cloud)? Or maybe your tests need exclusive access to a physical machine or VM?

Beaker is an integration testing system where every job has exclusive access to one or more freshly provisioned machines. Its unique features include fully customizable installations at the start of the job, detection of kernel panics and installation failures, and support for coordinating tests across multiple hosts in a single job. Beaker is an open source project originating out of Red Hat's unique needs for operating system-level and kernel-level integration testing.

If you're already an experienced user of Beaker, come along and share your tips and experiences with other Beaker users, and maybe you will learn about some Beaker features you never knew about.

Write Yourself an Annotation Processor
Feedback
Annotation processors were standardized in Java 6, but it wasn't until recently that they began gaining some popularity. In this talk, I will argue that they are a pretty nice form of compile-time metaprogramming, a facility which a lot of languages are sorely lacking. I will explain why it makes sense to write an annotation processor, show some real-world examples, both small and big, and then implement a simple yet useful annotation processor from scratch.

OpenShift v3: Docker, Kubernetes & the power of Cross Community Collaboration
Feedback
Linux Containers have quickly emerged as key open source application packaging and delivery technologies, combining lightweight application isolation with the flexibility of an image-based deployment method. In this session, we'll cover how OpenShift engineering has re-architected OpenShift V3 and collaborated with both the Docker & Google Kubernetes projects to build out the next generation of PaaS today.

This session will highlight the features and benefits of OpenShift V3's use Linux Containers including:
1) Application portability, allowing for the flexible deployment of the application container across multiple AWS regions, instances or availability zones;
2) Minimal footprint and boot time, reducing the overhead of deploying new application containers; 3) Simplified maintenance, reducing the effort and risk of patching applications and their dependencies; and,
4) Lowered development costs, as enterprises need only develop, test and certify applications against a single container runtime.

In this session, you will learn how OpenShift V3
(1) uses Docker to easily deploy pre-built applications;
(2) uses Kubernetes to manage container clusters; and,
(3) how Red Hat's OpenShift PaaS orchestrates source code deployment and centralizes management to leverage these technologies for the benefit of developers and administrators alike.

Using ansible for community managed infrastructure
Feedback
Starting a new community project is sometime a easy task, like creating a git repository on some popular services and be done with it. And sometime, the limitation of the simple approach are immediately visible and you need your own infrastructure to make sure your project grow in the right direction. This talk will be about using ansible to manage your own infrastructure, but with a twist, ie doing it in the open in a true community way. We will see the various pitfalls to avoid ( and lessons learned the hard way ), the example of potential deployment architectures and discuss various ways to ease the onboardong of new community members in the project.

Using Natural Language Processing To Make A Security Assistant
Feedback
Natural Language Processing (NLP) is an artificial intelligence user interface methodology where users can ask questions as if they were having a conversation with another person. During this presentation, a Computer Security Assistant will be demonstrated that can assess, secure, and monitor threats in a computer system just by having a conversation with it. This talk will go over Artificial Intelligence Markup Language (AIML) and how it functions to be the user interface to a smart assistant. By making AIML the user interface driver, it can also be shown that this security assistant can be converted to any other kind of assistant simply be changing out the AIML files. Hopefully this will inspire other developers to look into this technology.

Running a SIG in CentOS
Feedback
Special interest groups in CentOS is a way to build a specialized variant of CentOS to solve specific set of issues. SIGs have the freedom to add more cutting edge software or rebuild existing packages depending upon the requirement. This provides an excellent opportunity for the community to get best of both worlds i.e. stability of CentOS and newer technology from open source projects. This also creates a new way to consume technologies within CentOS ecosystem. In this session I will explain the process required to start a SIG along with little bit history and background. This session should give enough information to users so that they can get started with SIG.

System/Networking performance analytics with perf
Feedback
perf has become the defacto standard for linux performance analysis. Often the most basic commands are just enough to pinpoint bottlenecks and get a feeling what is going on. But perf is much more powerful...

In this talk we will explore what other features perf provides: Besides simply checking where the CPU spends most of its cycles, one can easily add custom tracepoints and capture arguments or return values from functions. We will do so on examples in the networking stack. This will be useful to isolate bugs or even validate patches.

In an outlook the talk will introduce the audience what performance counters are available on today's CPUs but not easily accessible in perf. A short introduction will be given on how the register and masks are to be interpreted from the CPU manuals and how they can be used from perf. As examples we will analyse the MOESI protocol and memory bus traffic between different NUMA nodes.

Bodhi2, MirrorManager2, progit, FAS3, anitya, the-new-coolness... What's going on in Fedora infra?
Feedback
The Fedora Infra folks have been working on a number of projects over the last year, some you have probably heard about, other likely not.
In this talk, I would like to present you what we have been doing, what is in progress and what we have in mind for the coming year.
This is of course not only a list of things worked, planned or in progress but also an invitation for anyone in the room to come, find a project they like and join us in making it real or better.
From mirroring, to account system via package update and rebuild, I'm sure there is a project to spike everyone's interest :)

Integrating Network Access and End Point Assessment with Trusted Network Connect (TNC)
Feedback
Traditionally network access control (NAC) has lacked endpoint assessment in its decision making. This lack of assessment can leave an enterprise's network vulnerable to malicious attacks. Trusted Computing Group (TCG) and IETF have defined an open architecture called Trusted network connect (TNC) to fill this gap. TNC, as part of its architectural components, includes integrity measurement collectors (IMCs) at network endpoints and integrity measurement verifiers (IMVs) at enterprise's network to evaluate and verify the endpoints against the enterprise policies before allowing network access.

This talk will cover:
1) What is end point assessment and why it is needed?
2) Why existing NAC technologies are missing end point assessment?
3) TNC architecture and how it can help with end point assessment?
4) What open source tools can be used to deploy TNC?

Super Privileged Containers (SPC)
Feedback
This session will cover building containers that need to manage the host OS.

For example containers that talk to dbus or systemd. Containers that load kernel modules or containers that actually modify host procesdes or content.

The goal of the lab would be to help users take existing packages and move them into a container environment and discuss how we can get them to work as a SPC.

rebase-helper - tool for fast rebases
Feedback
Package maintainers have to do a lot of manual tasks when new upstream version of a package is released. We identified that a lot of these tasks can be fully (or at least partially) automated to assist the maintainer. The rebase-helper is the tool to help package maintainers in various distributions with automating most of the tasks related with the package rebase. We intend to integrate the tool with Fedora infrastructure and Upstream Release Monitoring in the future, to help with assessing the difficulty of package rebase.

openconnect VPN
Feedback
Openconnect is a relatively new VPN solution. It started as a clone of CISCO's anyconnect VPN server, but it has now surpassed that role and provides a reliable VPN solution with a very conservative security architecture. This talk will address the question on the need for a new VPN solution given the plethora of open source VPN solutions, the distinctive features and capabilities of openconnect and an insight on the current development status.

Open Build Service, good, bad and ugly
Feedback
Open Build Service is an open source project to build packages and even whole distributions. It is mainly used by openSUSE, but also by Tinzen and others. Talk will start with generic overview of what it can do, what are the strong sides, mention few weak sides and also some of the ugly hacks that we use in our (not related to openSUSE) project. Also just for the fun of it, we tried to recompile whole CentOS on OBS to see how far would it go with minimum effort, so results of this simple experiment will be part of the presentation.

SCE wide system assessment for upgrading Fedora
Feedback
OpenSCAP and Preupgrade Assistant assists users to upgrade Fedora from the old major release (like F21) to newer major release (like F22). Basically Preupgrade Assistant calls OpenSCAP SCE engine. Preupgrade Assistant delivers a bunch of check scripts which assess the upgraded system and check scripts inform user whether there are problems with upgrade and helps user to upgrade system or not to the latest version. The alone upgrade is done by fedup tool.

This presentation has a aim to show users how SCE (part of openscap) can be used for wide system assessments.

Ceph FS development update
Feedback
Ceph provides a resilient and scalable storage model (RADOS) using clusters of commodity hardware. Along with the RADOS block device (RBD), and the RADOS object gateway (RGW), Ceph also provides a POSIX filesystem interface (Ceph FS). While RBD and RGW have been in use for production workloads for some time, efforts to make Ceph FS ready for production are now underway.

This presentation will introduce Ceph FS, explain its architecture, and provide an update on the latest development and testing work being done improve stability and manageability of the filesystem.

Security Threats at Conferences
Feedback
In this talk I will raise awareness for security threats against developers and contributors during conferences and show mitigation techniques and best practices to avoid them. A lot of attacks that happen less likely if someone uses the Internet from a secure station at home become dangerous, if for example WiFi networks at conferences are used. But there are a lot of
possibilities that allow to reduce the risk. Using the Fedora Project as an example I will show what can be done in the infrastructure and by the contributors to minimize the risk.

Efficient data maintenance in GlusterFS using Databases
Feedback
A major challenge for any distributed file system like GlusterFS, is conducting data maintenance without seriously affecting I/O response time. Solutions like a namespace crawl are inherently inefficient and may not provide correct information for any single point in time. Using a small, well integrated database provides a major improvement over a namespace crawl, with minimal impact to system performance. The talk will focus on the results of a study to integrate a database with GlusterFS. Also the talk will include a demo.
