As businesses move beyond experimentation to full-blown AI projects across the enterprise, they are recognizing that there’s more to successful implementations than simply having the right datasets, AI models and scalability. Increasingly, dimensions of trust, including fairness, robustness and explainability, are important metrics that help evaluate AI model behavior. Here, IBM is going to discuss how we are leveraging the power of Open Source to bring trust back in AI.

Over the past century, we have explored the solar system, split the atom, and wired the Earth, but somehow, despite all of our technical prowess, we have struggled to understand something far more important: our own cultural differences. Using a variety of methodologies, my research has uncovered is that many cultural differences reflect a simple, but often invisible distinction: The strength of social norms. Tight cultures have strong social norms and little tolerance for deviance, while loose cultures have weak social norms and are highly permissive. The tightness or looseness of social norms turns out to be a Rosetta Stone for human groups. It illuminates similar patterns of difference across nations, states, organizations, and social class, and the template also explains differences among traditional societies. It’s also a global fault line: conflicts we encounter can spring from the structural stress of tight-loose tension, and our data show that they have important implications for success in international mergers & acquisitions and expatriate adjustment, and can also help to explain some of today’s most puzzling political trends and events. An understanding of this template can help us develop more empathy and to bridge out cultural divides.

Benchmarking is a way of uncovering what best possible performance is and how can be achieved. It helps understand bottlenecks and real limitations of your system. Optimizing benchmark is not an easy job. Did you ever ask yourself how do you know that benchmark numbers are correct? How do you validate your benchmark? What if you are measuring the wrong thing? It’s important to have those answers as data from benchmark have a huge impact on purchasing and strategic decisions.
In this talk, Agata will walk you through an explanation of the benchmarking process, why is it so important to validate your data. She will also provide examples of bad optimization, and how to avoid common pitfalls.

Serverless promises on-demand, optimal performance for a fixed cost. Yet, we see that the current serverless platforms do not always hold up this promise in practice; serverless applications can suffer from platform overhead, unreliable performance, “cold starts”, and more.
In this talk we review optimizations used in popular FaaS platforms, and recent research findings that aim to optimize the trade-off between cost and performance. We will review function reuse, resource pooling, function locality, and predictive scheduling. To illustrate, we will use the open source, Kubernetes-based Fission FaaS platform to demonstrate how you can achieve specific goals around latency, throughput, resource utilization and cost.
Finally, we take a look at the horizon; what are the current performance challenges and opportunities to make FaaS even faster?

Despite their quick success and adoption, containers are already a well established technology and their use is steadily rising also in the embedded community. However the specific requirements of an embedded system set new challenges like running demanding graphical applications. While containers’ most common use case is to easily deploy headless server applications, graphical subsystem containerization is heavily dependent on the SOC GPU architecture. This session will provide an overview of the challenges encountered running X11 and Wayland applications inside docker containers on ARM SOCs. In particular we will focus on new advantages with respect to a traditional monolithic embedded OS but considering also container drawbacks and limitations. In our journey we’ll share our considerations and results with respect to different software setups, security & isolation, support for accelerated graphics and video decoding which are not an option on systems featuring a GUI.

Biometric authentication provides distinguished advantages over other techniques such as password-based ones; Biometric information is always with and unique to an individual, and hardly forgeable. One of the most classic biometric authentication is to use fingerprint, which is very popularly used these days in mobile banking or healthcare industry, for 2-factor authentication schemes. The benefits, however, come with an inherent risk: fingerprints cannot be changed once they are stolen.
In this talk, Seong-Joong Kim will address security problems that reside in the most popular open source for supporting fingerprint readers. After auditing, he found several flaws in encryption and key derivation process of the project, which may lead to dreadful consequences: an attacker can extract individual fingerprint images between a fingerprint scanner and a host, or can steal original fingerprints from the fingerprint DB. He will demonstrate those attacks and discuss possible countermeasures.

Historically, Indeed has used Boxcar (Indeed’s proprietary framework) to build distributed systems. Over the last year, we have been shifting several of our systems to use gRPC over an Envoy service mesh. While product teams are comfortable adopting the service mesh, the first question they often ask is “How does gRPC compare to Boxcar?”
In this presentation, I put the two frameworks head to head and present the results. I show how my team established some common workloads and gathered metrics to better inform other engineers. We learned a lot about how to tune the gRPC Java library and service mesh when performing this analysis.

Real-time applications need to satisfy timing constraints, and we have to avoid kernel changes which might cause long delays. But we need tons of time for testing to detect those issues. So, it is the reason why we use automated testing frameworks.
We presented our test with "Fuego" in ELCE2018, which not only measures performance but also traces for detecting what cases delay. Now, we have developed Functional-test run-time logger which measure the amount of time required to finish the functional test, to get clues to detect internal problem even if all of the test’s results is success. In this presentation we will share the detail of the run-time logger in Fuego with showing our actual use case. KEYWORDS: Fuego, LTP, strace, Performance test

Though machine learning and AI are immensely powerful, these solutions are by no means easy. In many cases, there are many diverse components that are not designed to work together. Additionally, these models are most efficient when running on large scale clusters that can be more difficult to manage. Configuration and deployment is often left to data scientists who are wasting time on infrastructure and not on data science itself.
Kubernetes to the rescue! In this session I will talk about how machine learning can be greatly improved by implementing ML solutions on top of Kubernetes with containers. I will be discussing each stage of a typical workflow including: data preparation/versioning, model training, testing and validation, monitoring, and CI/CD and automation. Demos will include tooling such as Tensorflow/Kubeflow, Pachyderm, Argo, etc.

Rapid application innovation is characterized in part using shared code from open source components. While open source development offers many benefits, when regulators change the rules our strengths can prove problematic for ongoing regulatory compliance. For example, in January 2019 French regulators highlighted that the initial experience with Android violated consent and transparency provisions in GDPR imposing a hefty fine upon Google. Given privacy regulations like GDPR exist due to security issues within product offerings, it’s time to look at software development not just through a security lens but also through a consent and privacy one. In this session we’ll cover: - Security expectations regulators are creating for consumers - How to identify sensitive data as defined by regulators - The role and lifecycle of user consent in product operations - Models to identify data processing and third-party data transfers

By now most people are familiar with what it means to be a serverless platform, features such as scale-to-zero, auto-scaling and source-to-build. And Knative certainly does all of that. But, by calling Knative a Serverless platform are we implying that PaaS or CaaS apps shouldn't share some of these same characteristics? I don't think so - so let's stop this charade! In this talk we'll go over what Knative is, and how we really should look at it as a new way to deploy any app to Kubernetes - not just functions.
Developers should focus on writing code, not managing infrastructure. With Knative we take a huge step forward towards abstracting the complexities of Kubernetes w/o giving up the advanced features we all want.

Jitterdebugger is a new tool for testing the preempt_rt real-time extensions for the Linux kernel. While the basic principles for this endeavor (run a cyclic task on one or more CPUs, and store the measured latencies) seem very straightforward at a first glance, the devil is in the details -- in particular, if evaluations beyond computing simple descriptive results should take place, and if machines and systems are subjected to systematic testing over long periods of time.
The talk starts with an introduction to architecture and usage of the jitterdebugger tool, and will (of course) also address the question of how it differs from the cyclictest tool suite. We will then discuss archival strategies for keeping recorded data reproducible in the long run (a non-trivial problem!), and discuss several types of statistical evaluation that are made possible by jitterdebugger's new capabilities.

Most users and developers don’t think too closely about what kernel is running, yet the kernel is a vital piece of software. There are many choices of what kernel to run, from a well-tested enterprise kernel to forward-looking community distributions to running your own compiled version. Each of these options has a use case and the choice of the kernel can have a big impact on your system. So how do you choose? The focus of this talk is the many ways a kernel can be maintained and what it means for consumers of that kernel. Emphasis will be given to the trade-offs of features vs. security vs. ease of management and mistakes you can make when maintaining a kernel.
The rise of new AI and ML requires new workflows and new tools: data versioning, ML pipeline versioning, experiments metrics visualization and others that have not been formalized and even named yet.
The traditional software engineering toolset does not fully cover ML team's needs. We will discuss the current practices of organizing ML workflow using traditional open-source tools like Git and Git-LFS as well as their limitations. Thereby motivation for developing new ML specific experiments and data management systems will be explained.
ML workflow differs from software engineering. Experimentation, trials-and-errors nature of ML projects and the need in more granular and efficient data artifacts management requires new sets of development tools. We will show ideas behind open source tool DVC or http://dvc.org which focuses on working with ML experiments, managing large datasets, and ML model.

Mobile OSes, such as Android, have spread to non-smartphone use cases such as in-vehicle infotainment, and physical retail stores. These scenarios often require the installation of multiple standalone mobile devices to simultaneously serve different users. Meanwhile, computing capacity has increased quickly even on relatively low-cost computing platforms. To reduce the total cost of ownership, it is natural to ask: Is it possible to host multiple simultaneously interactive mobile clients on a shared computing platform? This topic presents AIC, a system to support multiple simultaneous interactive clients on a shared computing device. AIC reduces total cost of ownership, lowers management overhead, and supports dynamic sharing of system resources. AIC offers every client a full mobile OS instance that is virtualized based on container-like OS virtualization technology.

Compilers toolchains are at the core of the building the Embedded Linux Systems, it affects the full system from bootloaders, kernels to applications and platform software, compilers are software too, therefore knowing about how this can help to achieve code size, performance optimization is quite powerful insight to have for programming the systems. There are optimizations which are effective in embedded systems, provided by compilers via command line, but there is another class of coding practices, that can help the compiler to generate best code for a given algorithms, modern compilers are quite good at optimizing general code, however this can be made more effective by knowing these practices and help the compiler to compile to generate better code. Knowing the compiler can add that extra edge to programming techniques which can result is effective code. Clang and gcc are primary compilers for linux systems, so knowing the options to generate smaller, better code is the goal.

Linux is the default choice of modern IT system including IoT, Embedded and many others. For IT system, historically, commercial distros are providing distribution with security and bug fixes in Long Term. That has a huge number of continuous testing and fixing in backside to provide professional support.
On the other hand, Embedded space is very different. Every company needs to roll up their own distribution by themselves with picking the best kernel and evaluate it on their own. Sometimes it will be the duplicated effort even we are using Open Source.
LTSI had been established to find a way to solve such issue and continued to advocate using LTS kernel.
I will present kernel development process with the latest statistics to find the best recommended LTS kernel with surrounding community situation.
Then, I will cover what is happening for Linux testing activities. Also, cover Open Source Licensing topics which should be known for the people using Linux for their products.

What if it was possible to query your data using aggregation functions, windowing, and grouping results while the data was in motion and in-memory but on the edge side?
In Data Analysis, logging is one of the key components to collect and pre-process data, usually, a logging mechanism goes through collect, parse, filter and centralize logs to a storage backend like a database, so data processing and analysis can be performed. This usually happens after the data has been aggregated and stored, but for real-time analysis needs, process the data while is still in motion brings a lot of advantages and this kind of approach is called Stream Processing.
In this presentation, we will go further and present an extended approach called 'Stream Processing on the Edge', where data is processed on the edge service or device, in a lightweight mode empowering features like anomaly detection (in the order of milliseconds) and Machine Learning in a distributed way using pure Open Source software.

Linux is a versatile operating system; it can power smart watches, mainframes and everything in between. However, if a constrained device only possesses a few megabytes of memory and a CPU running at a few dozen megahertz, Linux will simply not fit. Enter the Zephyr real-time operating system (RTOS), from the Linux Foundation. Zephyr is a really small footprint, real-time operating system built with security and safety in mind for highly constrained environments. It can go where Linux can't.
Having a great OS is only the first step in building a constrained device. You will also need to manage it and exchange data with it. In this presentation, you will learn how to do both using the Eclipse Paho MQTT client and the Eclipse Waakama OMA Lightweight M2M (LWM2M) library. You will also discover other components of the Eclipse IoT system that could be useful to you, and even learn the basics of Zephyr if you are new to it.

A key aspect to maintaining device security is monitoring and addressing known vulnerabilities in open source software in a timely fashion. This presentation will help you get started with the process of monitoring CVE's, determining applicability, assessing the severity and finding fixes.
We take a deeper dive into some of the challenges in tracking CVE's due to NVD/MITRE feeds having incorrect/missing data, leading to missed vulnerabilities and a false sense of security. The problem is compounded by inaccuracies in scanning tools and the way fixes are tagged in build systems resulting in a alarming number of false positives.
We review the CVE's reported by cve-check-tool in Yocto and determine the root cause for inaccuracies. We also discuss techniques to mitigate the issues so that the entire community can benefit. This presentation will enable you to improve your device security posture.

Static partitioning is used to split an embedded system into multiple domains, each of them having access only to a portion of the hardware on the SoC. It is key to enable mixed-criticality scenarios, where a critical application, often based on a small RTOS, runs alongside a larger non-critical app, typically based on Linux. The two domains cannot interfere with each other.
This talk will explain how to use Xen for static partitioning. It will introduce dom0-less, a new Xen feature written for the purpose. Dom0-less allows multiple VMs to start at boot time directly from the Xen hypervisor, decreasing boot times drastically. It makes it very easy to partition the system without virtualization overhead. Dom0 becomes unnecessary.
This presentation will go into details on how to setup a Xen dom0-less system. It will show configuration examples and explain device assignment. The talk will discuss its implications for latency-sensitive and safety-critical environments.

Improving boot time is always a delicate matter and literature is very rich. Linux based OSes benefit from standard optimization approaches however, Android is still far away from having exciting results especially because most the heavy block happens in user space. Hibernation, suspend-to-disk, is undoubtedly a different perspective to look at improving boot time. When the hibernation mode is entered the system hardware state is copied to non-volatile memory like MMC and all power can be removed by the system. On resume, the system is restored from peripherals to memory in a predetermined way. From this perspective just the very first boot will be a “regular” one and all the subsequents is just a restore operation which can take a few seconds. This session will provide the current state of the kernel development of Hibernation on ARM architectures and our tests on the popular i.MX family of processors including the new i.MX8 which today is one of the most promising SOCs.

Organizations use containerized workloads to build and deploy applications. Although diverse in nature these deployments must conform to company-wide constraints around cost, security, and performance. These evolving constraints affect the entire stack and hence enforcing them becomes difficult. In this talk, we will introduce the Open Policy Agent (OPA), an open source, general-purpose policy engine which can be used to enforce fine-grained policies in any system and at any layer of the stack. We will see examples of authoring security policies using OPA’s purpose-built, declarative language over JSON data gathered from Kubernetes. OPA not only provides the ability to enforce organization-specific policies by leveraging security extension points in Docker and Kubernetes such as admission controllers but also meets strict latency and availability requirements. We will demo how custom policies can be enforced on Kubernetes objects without modifying any Kubernetes components.

Life's too short to be running “dd” on sd cards all day. The Aktualizr project includes a new tool called aktualizr-lite that can handle secure OSTree updates in a highly scalable manner. Aktualizr is great project implementing the Automotive industry’s Uptane specification. Many use cases don’t require the full Uptane specification and really only need secure updates that can be verified using TUF. aktualizr-lite is the tool that makes this possible.
By using OSTree updates embedded devices can be managed without constant reformatting of sd cards and developing complex test automation systems with things likes sd muxes and emulators. The end result is something users enjoy, testers and CI can rely on, and developers can trust.
This talk will discuss what OSTree is, how it can be incorporated into Open Embedded, and how Aktualizr can handle updates.

A myriad of connected electronic devices can now be monitored and controlled using a smart phone, or via voice commands. User-friendly interfaces are making “smart products”, aka Internet of Things (IoT) devices, more approachable than ever. Although IoT promises to bring us numerous benefits, what are the hidden risks?
This talk will highlight 7 popular “features”, advertised as benefits, that we instead expose as “unhealthy habits”. One example is the notion of “end-to-end security”. Imagine you want to allow a brand A wireless pushbutton to control a brand B smart bulb. If each device uses end-to-end security, the result is two separate device-to-cloud walled gardens, and no interoperability.
To help overcome each unhealthy habit, we will suggest alternative solutions using Mozilla’s open source web of things framework. Mozilla envisions an open and decentralized IoT ecosystem that puts people first, to improve the privacy, security, and interoperability of connected devices.

Whether you’re using Chef, Puppet or Ansible, you’re going to need a set of tools which help enable you to develop and test your infrastructure. One set of tools that we use at the OSU Open Source Lab is test-kitchen coupled with InSpec. Test-kitchen provides a test harness to execute infrastructure code on one or more platforms in isolation. InSpec provides a way to ensure your infrastructure code passes tests and compliance in a way separate from your configuration management. Together, this provides a very powerful platform for developing infrastructure code and testing it as well.
This session will introduce attendees to both test-kitchen and InSpec, explain the various drivers and provisioners you can use, and also provide some real-world examples of how to use it with Chef, Puppet and Ansible.

XIP stands for eXecute In Place – a technology that allows code to be executed directly from flash without copying the code to RAM first. Today, interest in XIP Linux has been revitalized due to the possibility of running Linux on memory-constrained IoT devices and the capabilities of some SoCs to execute Linux in place from QSPI flash. The memory footprint can be optimized very tightly and this opens up to a really low-power IoT Linux appliances.
However, there is a big obstacle for the XIP approach to spread widely: no standard secure update process for such systems will work due to the nature of XIP - flash should always be ready to execute from, so how can it be updated? This talk will answer this and provide some real world examples.

You find them everywhere in software projects, bash scripts are the duct tape and chewing gum that hold together all the disparate software services. They are frequently used to wrap java programs, initialize docker containers, to boot virtual machines, and/or to run configuration management steps. Bash is installed on all linux machines out of the box, so mastering bash scripting can dramatically increase any developer’s productivity. It can be used to quickly solve many different mundane, tedious, and simple tasks. In spite of all this, many developers still struggle and find bash scripts unmaintainable. With so much legacy code written in bash, it is not going anywhere soon. In this presentation you will learn invaluable tricks, tips, shortcuts, and advice for developing bash scripts that are maintainable. Developers will leave with many ideas for how they can improve their own scripts and automate their daily tasks. Practice exercises will be provided at the end.

This presentation is about why and how to build an open and neutral architecture for edge computing on heterogeneous devices.
In the era of IoT and edge computing, the global industry becomes more and more fragmented with hundreds and thousands of technical stacks. It's quite painful for customers and users to struggle how to select proper one among them and how to ensure reasonable TCO for 10+ years' usage in production, without lock-in and prime fee for certain vendors.
With open source software and open standard APIs, it is possible to build and maintain an open and neutral architecture on heterogeneous edge devices. Similar to IT infrastructure in data centers and clouds, edge device architecture could be put into infrastructure, app framework, software service layers, bottom up. Virtualization, Linux, containers, EdgeX Foundry, marketplaces, all are leveraged to build this layered open and neutral architecture for extensible edge computing. A set of OSS projects are built as the reference implementation.

In this talk, we will be discussing the seven key properties of a secure IoT device–hardware-based root of trust, small trusted computing base, defense in depth, compartmentalization, certificate-based authentication, security renewal, and failure reporting–and their implications at the hardware and software level. We will use an off-the-shelf MCU with an on-chip security coprocessor as an example of how these properties can be realized in practice for IoT devices
This talk is an opportunity to have a "non-hand-waving”/non-FUD discussion about IoT security needs in terms of important properties. Even if you are not a security expert, join the session to hear about some guidelines and best practices so that you can make informed decisions when it comes to your hardware and software security choices.

The Linux kernel has had an in-kernel debugger for many years, but shockingly few people are setup to use it. In this tutorial I will demonstrate how to use kgdb for debugging kernel crashes on systems that have a serial port. As part of this session I will show how to get kgdb setup, how to drop into the debugger, and how to debug several simulated bugs in the kernel.
The focus on the session will be on after-the-crash debugging rather than using kgdb to step through code.
This session should be useful to developers at all levels from kernel noobs to developers with years under their belts.

KernelShark is an Open Source front end GUI for Ftrace, the official tracer of the Linux kernel. It was started in 2009 by Steven Rostedt and written in GTK. It was Steven's "idle task" where he worked on it only when he had time. It was useful, but not fully featured. It has since been completely rewritten in Qt by Yordan Karadzhov, with the guidance from Steven. Now it is a fully functional tool, which is much faster and much more featureful than the original. KernelShark never made it to 1.0 until now. Come to the talk and see what all the hype is about. See a live demo and even get a glimpse into what is coming in KernelShark 2.0.

Product makers can now solve complicated connectivity issues by adding low power LTE Cat-M1 and NB-IOT modems to their products. However, the software for these modems is far from standard and often has to be customized by use-case. In response, the Zephyr Project now has some basic modem driver implementations which provide transparent access to the networking stack in the same way as if the device had ethernet or an 802.15.4 adapter. This presentation will discuss which hardware is currently supported, and how these drivers were implemented using the offloaded networking stack. Michael will end with open discussion around the challenges of future modem APIs for a basic 3GPP interface, eDRX / power saving modes and modem configuration settings storage.

The PC world and embedded systems have mostly followed their own paths when it comes to firmware design. PCs grew up around BIOS followed by EFI which eventually became the UEFI specification, and finally gaining Secure Boot for verifying OS images. Embedded has used many different firmware projects, with U-Boot becoming the most popular, and as such has developed its own interfaces and methods for verifying and booting an OS.
Unfortunately very little of the U-Boot interface has been standardised which resulted in every U-Boot platform behaving slightly differently. This makes it very difficult for OS distributions to support more than a handful of embedded platforms. To solve this problem, U-Boot is in the process of adopting the UEFI standard for ABI and boot behaviour, including secure boot functionality. This presentation will go over the current state of UEFI and Secure Boot on U-Boot, including how to use it and future plans.

One of the most common persistent memory technology in today's embedded Linux devices is eMMC flash memory. The raw NAND flash used inside the eMMC chips has a limited number of write cycles. To get a long lifetime several tactics are employed such as wear level algorithms and error correction. From the low-level firmware on the eMMC controller across several layers of software, it is rather difficult for an application programmer to understand what particular wear his program imposes on the underlying flash. We are discussing an implementation to monitor the flash usage on the block level which can be used to make more accurate lifetime estimations and provide feedback to an application program for storage-related optimizations.

High performance internationalization support is coming to the main Linux filesystems. Historically, file and directory names have always been treated as opaque byte sequences by Unix kernels, in opposition to what was always done in Windows and MacOS. This design decision reduces the complexity of filesystem implementations, allowing them to defer meaning (encoding) to upper userspace layers, but it falls short, on the other hand, when the encoding information is required in kernelspace, for instance when case-insensitive filesystem lookups are needed. This talk will present the reasoning and use cases for in-kernel case-insensitive name lookups and the new Unicode interface for Ext4 that is being merged in the Mainline Linux kernel.

EdgeX is an open source hardware-agnostic framework for IoT and Edge Computing. It is composed of a series of docker containers acting as micro-services that allow developers to plug and play from the growing ecosystem of third-party components or even your own proprietary software. With an automotive IoT proof of concept, we demonstrate how a developer can create an entire vertical solution with a Raspberry Pi, inexpensive GPS and OBD, and EdgeX.
Our proof of concept is capable of serving data to multiple different cloud endpoints, which we implement through three different use cases: an insurance company, a smart city, and a personal driving record. Through these use cases, we showcase the advantages of an edge computing architecture in the context of IoT like data manipulation, reduction, anonymization and aggregation. Come join us to learn about EdgeX in the context of developing Automotive IoT Applications.

Surprisingly, often it's hard to find the precise correspondence between a known software vulnerability (in CVE) and the exact origin of the software (Maven coordinates or github repo/tag). Ideally, this connection would be part of CVE. However, currently, it is not, and creating this correspondence often requires significant human effort.
Dave and Peter introduce Canvass Labs' open-source implementation and discuss techniques it uses to solve this problem. They show how to parse and map CVE information, quantify the current statistics of this correspondence, and discuss the free open data produced by their open-source tool and its further use.
Currently, most Java and JavaScript projects do not add CVE information in their fixes. They show that if OSS engineers were to add CVE information when they commit (as in Linux or OpenSSL), then big data and AI practitioners can create an AI programming assistant that can identify similar bugs and suggest fixes.

Kubernetes offers a unique opportunity for organizations to build a production-grade RDS-like service running on their own infrastructure: either on-premises or in the public cloud. Using Kubernetes Operators (along with its built-in HA, scaling and monitoring), you can now enable a DB-as-a-Service solution on any environment - to avoid cloud lock-in and save costs.
This talk covers the key considerations for choosing Kubernetes as the backbone for your relational database service, and how to get your MySQL-as-a-Service up and running using open source tools and Operators for the easy deployment and management of MySQL instances that can run anywhere.
We share our journey moving production workloads from AWS RDS to our own MySQL Kubernetes service running on our private cloud. We discuss the architecture design, challenges we encountered, best practices, and the open source tools we used (along with code samples) -- so you could implement your own DB service running on Kubernetes.

When doing development for a new SoC or BSP, a series of patches are created to get the hardware functional on Linux, u-boot, and other software. Yocto can be used as an easy way to get a functional distro with these changes. However, it is often overlooked as a way to upstream those patches. This talk will cover using Yocto for this. Using a Samsung S5P6818 based board as an example, we will discuss the patches necessary to get the system working, updating to the latest kernel/u-boot, and pushing the relevant patches upstream, and tracking those patches. This will provide information and best practices for those in attendance.

Speakup is a screen reader for Linux. Originally written by a blind person, speakup is a cool piece of software in more than one way:
It entirely lives in kernel
The only screen reader which starts speaking very early on during boot, before there is even the user space - some interesting techniques used to achieve that and we'll look into them!
Speakup is also a driver which has to talk to hardware but it never directly talks to a physical port. Told you it's cool :)
Currently in staging/ directory of mainline Linux kernel but on the verge of being moved out into kernel proper. So expect it in your main distros going forward
We'll cover the story of speakup, how it started and evolved to where it is now and where it's headed. Then we will try to cover some technical details which will touch some kernel internals too. In the end we'll look at speakup's development process and finally Q&A. Feel free to check out the slides deck for a more intelligent conversation during the talk.

Building a secure connected device is a complex challenge. - Provisioning of a device requires handling of secrets. While creating a ‘physically secure’ facility is an accepted way of securely provisioning a device, this doesn’t scale very well in a globally distributed supply chain model - In a multivendor (hardware and software vendors) scenario, mutual trust needs to be minimized - The integrity of the system (hardware/software) needs to be guaranteed - Devices need to be able to support secure connectivity - Cloud entity must be able to ‘attest’ the device’s current status to be able to decide the ‘quality of service’ it should offer to a device - Firmware must be updatable to mitigate newly discovered threats
This talks elaborates on these challenges and explains the steps involved in building a secure connected device. It also covers how these challenges are addressed in the context of Platform Security Architecture(PSA) and Trusted Firmware M project.

Once a new device leaves IT and enters user hands, maintaining confidence in the security of the device is a challenge. When access to network resources relies on credentials provided by the device, remote systems cannot tell the difference between a secure device running a trusted operating system and an adversary.
Most modern machines have TPMs, and every TPM has its own cryptographic identity. Firmware and bootloaders use the TPM to generate verifiable logs of the entire boot process - but this data is rarely used to its full potential. In this talk, we explain how Google uses this functionality to build trust in a fleet of geographically diverse machines. We discuss the challenges of establishing a strong, hardware-backed identity for each machine, and how we use remote attestation to prove our devices are running a sanctioned boot chain. Finally, we present newly-released cross platform open source libraries we have built to allow anyone else to build equivalent infrastructure.
