Using Rally for OpenStack certification at ScaleBoris Pavlovic
It goes without saying that one of the most important things all OpenStack clouds from big to small is to be 100% sure that everything works as expected BEFORE taking on production workloads.
To ensure that production workloads will be successful, we can do a few key things:
1) Generate real load test from "real" OpenStack users
2) Collect and retain detailed execution data for examination and historical comparison
3) Measure workload performance and failure rate against established SLAs to validate a deployment
4) Visualize results in beautiful graphic detail
Rally can fully automate these steps for you and save dozens if not hundreds of hours.

Performance Test Automation With GatlingKnoldus Inc.
Gatling is a lightweight dsl written in scala by which you can treat your performance test as a production code means you can easily write a readable code to test the performance of an application it s a framework based on Scala, Akka and Netty.
Given at the 010PHP usergroup.
As developers we often want to use the latest software and be able to deploy as quickly as possible. Both of these are often not reasonable to accomplish with traditional infrastructure, as it can cost a lot of time, with or without an ops team. How can we make the move to a more fast-paced environment, where we can spend more time on features, and less time on ops? In this talk I will give you insights into our journey to Kubernetes, the orchestration platform for containers. I hope to give you a good case study and tips for moving to Kubernetes, or making any big platform change in general.

Ensuring Performance in a Fast-Paced Environment (CMG 2014)Martin Spier
Netflix accounts for more than a third of all traffic heading into American homes at peak hours. Making sure users are getting the best possible experience at all times is no simple feat and performance is at the core of this experience. In order to ensure performance and maintain development agility in a highly decentralized environment/(organization?), Netflix employs a multitude of strategies, such as production canary analysis, fully automated performance tests, simple zero-downtime deployments and rollbacks, auto-scaling clusters and a fault-tolerant stateless service architecture. We will present a set of use cases that demonstrate how and why different groups employ different strategies to achieve a common goal, great performance and stability, and detail how these strategies are incorporated into development, test and DevOps with minimal overhead.

Join this info-packed and hands-on workshop where we will cover:
Introduction to Kubernetes & GitOps talk:
We'll cover the most popular path that has brought success to many users already - GitOps as a natural evolution of Kubernetes. We'll give an overview of how you can benefit from Kubernetes and GitOps: greater security, reliability, velocity and more. Importantly, we cover definitions and principles standardized by the CNCF's OpenGitOps group and what it means for you.
Get Started with GitOps:
You'll have GitOps up and running in about 30 mins using our free and open source tools! We'll give a brief vision of where you want to be with those security, reliability, and velocity benefits, and then we'll support you while go through the getting started steps. During the workshop, you'll also experience in action and see demos for:
* an opinionated repo structure to minimize decision fatigue
* disaster recovery using GitOps
* Helm charts example
* Multi-cluster example
* all with free and open source tools mostly in the CNCF (eg. Flux and Helm).
If you have questions before or after the workshop, talk to us at #weave-gitops http://bit.ly/WeaveGitOpsSlack (If you need to invite yourself to the Slack, visit https://slack.weave.works/)

Testing cloud and kubernetes applications - ElasTestMicael Gallego
Kubernetes applications are complex distributed systems composed by several microservices. When some end to end test is failing in these kind of applications, root cause is difficult without good observability tools. In this presentation, several tools are presented to make easier root cause analysis of cloud and kubernetes applications. One of the most interesting ones is ElasTest, a platform that integrates several open source tools to provide observability to e2e testing of complex distributed systems.

Deep Learning Neural Network Acceleration at the Edge - Andrea GalloLinaro
Short
The growing amount of data captured by sensors and the real time constraints imply that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in Arm-based platforms provide an unprecedented opportunity for new intelligent devices. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators.
Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, accelerator solutions, and will describe the efforts underway in the Arm ecosystem.
Abstract
The dramatically growing amount of data captured by sensors and the ever more stringent requirements for latency and real time constraints are paving the way for edge computing, and this implies that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in recent Arm-based platforms provides an unprecedented opportunity for new intelligent devices with ML inference. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators.
Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, model description formats, accelerator solutions, low cost development boards and will describe the efforts underway to identify the best technologies to improve the consolidation and enable the competitive innovative advantage from all vendors.
Audience
The session will be useful for executives to engineers. Executives will gain a deeper understanding of the issues and opportunities. Engineers at NN acceleration IP design houses will take away ideas for how to collaborate in the open source community on their area of expertise, how to evaluate the performance and accelerate multiple NN frameworks without modifying them for each new IP, whether it be targeting edge computing gateways, smart devices or simple microcontrollers.
Benefits to the Ecosystem
The AI deep learning neural network ecosystem is starting just now and it has similar implications with open source as GPU and video accelerators had in the early days with user space drivers, binary blobs, proprietary APIs and all possible ways to protect their IPs. The session will outline a proposal for a collaborative ecosystem effort to create a common framework to manage multiple NN accelerators while at the same time avoiding to modify deep learning frameworks with multiple forks.

Bud17 113: distribution ci using qemu and open qaLinaro
“Delivering a well working distribution is hard. There are a lot of different hardware platforms that need to be verified and the software stack is in a big flux during development phases. In rolling releases, this gets even worse, as nothing ever stands still. The only sane answer to that problem are working Continuous Integration tests. The SUSE way to check whether any change breaks normal distribution behavior is OpenQA. Using OpenQA we can automatically run tests that hard working QA people did manually in the old days. That way we have fast enough turnaround times to find and reject breaking changes This session shows how OpenQA works, what pitfalls we had to make ARM work with OpenQA and what we’re doing to improve it for ARM specific use cases.”

HKG18-501 - EAS on Common Kernel 4.14 and getting (much) closer to mainlineLinaro
Session ID: HKG18-501
Session Name: HKG18-501 - EAS on Common Kernel 4.14 and getting (much) closer to mainline
Speaker: Chris Redpath
Track: Mobile, Kernel
★ Session Summary ★
This session will introduce the changes to EAS planned for 4.14 kernel, and how Arm hopes that EAS will develop in future. EAS has already evolved from an Arm/Linaro joint project to involving a much wider community of SoC vendors, Google and interested device manufacturers. We will highlight the product-specific pieces remaining in the Android Common Kernel EAS implementation, and our plans to provide an upstreaming plan for each product feature. In particular, the new 'simplified energy model' is designed to provide mainline-friendliness and comparable performance using a simple DT expression of cpu power/performance.

Speaker: Alex Bennée,Richard Henderson
Track: Enterprise
★ Session Summary ★
ARM's Scalable Vector Extensions is an innovative solution to processing highly data parallel workloads. While several out-of-tree attempts at implementing SVE support for QEMU existed, we took a fundamentally different approach to solving key challenges and therefore pursued a from-scratch QEMU SVE implementation in Linaro. Our strategic choice was driven by several factors. First as an ""upstream first"" organisation we were focused on a solution that would be readily accepted by the upstream project. This entailed doing our development in the open on the project mailing lists where early feedback and community consensus can be reached.

HKG18-120 - Devicetree Schema Documentation and Validation Linaro
"Session ID: HKG18-120
Session Name: HKG18-120 - Structured Documentation and Validation for Device Tree
Speaker: Grant Likely
Track: Kernel
★ Session Summary ★
Devicetree has become the dominant hardware configuration language used when building embedded systems. Projects using Devicetree now include Linux, U-Boot, Android, FreeBSD, and Zephyr. However, it is notoriously difficult to write correct Devicetree data files. The dtc tools perform limited tests for valid data, and there there is not yet a way to add validity test for specific hardware descriptions. Neither is there a good way to document requirements for specific bindings. Work is underway to solve these problems. This session will present a proposal for adding Devicetree schema files to the Devicetree toolchain that can be used to both validate data and produce usable documentation.

Track: LITE
★ Session Summary ★
An overview of the trusted boot concept and firmware update on the ARMv8-M based platform and how MCUBoot acts as a BL2 bootloader for TF-M.
Trusted Firmware M
In October 2017, Arm announced the vision of Platform Security Architecture (PSA) - a common framework to allow everyone in the IoT ecosystem to move forward with stronger, scalable security and greater confidence. There are three key stages to the Platform Security Architecture: Analysis, Architecture and Implementation which are described at https://developer.arm.com/products/architecture/platform-security-architecture.
_Trusted Firmware M, i.e. TF-M, is the Arm project to provide an open source reference implementation firmware that will conform to the PSA specification for M-Class devices. Early access to TF-M was released in December 2017 and it is being made public during Linaro Connect. The implementation should be considered a prototype until the PSA specifications reach release state and the code aligns._

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

■ Git (git.linaro.org)
■ Bazaar (bazaar.launchpad.net)
● Build the code
○ Use a build system
■ Jenkins (ci.linaro.org and android-build.linaro.
org)
■ LAVA (yes, LAVA can be used!!!)
● Publish the build results
○ Build artifacts are available (snapshots.linaro.org)
Anatomy of CI loop
11. ● Submit the results for testing
○ LAVA (validation.linaro.org)
● Get the tests results
○ E-mail notifications with filters (validation.linaro.
org/lava-server/dashboard/filters)
○ LAVA dashboard (validation.linaro.org/lava-
server/dashboard)
Anatomy of CI loop
12. ● Different type of jobs
○ Kernel CI
○ Engineering builds
○ Components
● Build triggers
○ manual, periodically, URL trigger, post-commit
● Do the build
○ shell script(s)
■ can be maintained under SCM (linux-preempt-rt)
○ Groovy script(s)
● Publish
○ to snapshots.linaro.org
○ to package repositories (PPA, other)
Build jobs in depth
13. ● Submit to LAVA
○ Generate a LAVA job file (json)
○ test definitions are pulled from SCM (git.linaro.
org/gitweb?p=qa/test-definitions.git)
● Misc
○ Jenkins can run unit tests (e.g qemu-ltp job)
■ junit

○ mirrors and caching
● Better documentation
CI Future
18. Manual Testing
Current approach:
● test results are not very detailed
● no connection between test case description and result sheet
● results stored in google spreadsheet
● bug linking done manually (makes it hard to extract the list of 'known
issues')
19. Future:
● store test cases in some better suited place than wiki
● preserve test case change history
● store manual test results along automatic ones (in LAVA)
● have ability to link bugs from various tracking systems to failed cases (in
LAVA)
● generate reports easily (known issues, fixed problems, etc.)
○ might be done using LAVA if there is an easy way to extract testing
results (for example REST API)
Manual Testing
20. ● Monitoring dashboard
○ adding bugs
○ debugging failed runs
● Creating custom dashboards
○ Dashboard from filter
○ No need to edit python code to create/edit dashboard
○ Private/public dashboards
○ Dashboard email notification (falls in the concept of filter-as-dashboard
approach)
Dashboards
21. ● Use only binaries that were already automatically tested
● Don't repeat automated tests in manual run (we have to be confident that
automated results are reliable)
Release workflow
22. LAVA: Faster, Higher,
Stronger (& easier to use)

● Other organizations (incl. Linaro members)
interested in running their own LAVA lab
We need to go from an in-house service to a
solid product
Context (1)
26. ● No bootloader testing
● Tests only involve single devices
We need to provide features to support new
demands in test and validation
Context (2)
28. ● Queue size monitored with munin

Packaging enhancements
30. Easing LAVA learning
● Documentation is
○ scattered
○ outdated
○ confusing
Documentation overhaul is in the LAVA
roadmap.
Documentation overhaul
31. Easing LAVA usage
ATM a lava-test-shell job requires
● 1 JSON job file
● 1 YAML test definition file
● + the test code itself

$ lava script submit mytestscript.sh
$ lava job list
LAVA test suite helper tool
32. Getting more out of LAVA data
More information out of LAVA data
● Improvements in test results visualization in
the LAVA dashboard
33.
34. LAVA is too hard to develop

○ Also a mess for bug/project management
● Requires almost a full deployment for
development
● Consolidated client components (3 to 1)
● Will consolidate server components (3+ to 1)

36. ● LAVA Multi-purpose Probe
● 1 base design, 5 boards now
● USB serial connection(s) to the host
● management of other connections to/from
devices under test
