Embracing Openness to Power Future Network Services

By Arash Ashouriha, SVP Technology Architecture & Innovation, Deutsche Telekom

This post first published on

The exponential Internet traffic growth is still one of the main challenges for the Telco industry. In the past, Moore’s Law has helped us to keep our production cost for the exponentially growing traffic under control. With Moore’s Law flattening out, we see a strong trend in the industry towards the disaggregation of hardware and software. From monolithic black-box solutions, we are moving towards a modular, best-in-class, flexible and open ecosystem, including an automated lifecycle management in true DevOps style. None of the Telcos can do this on their own – the success of this industry depends on collaboration.


Beside its engagement in the Telecom Infra Project (, Deutsche Telekom has now joined the Linux Foundation as a Silver member, and The Linux Foundation Networking Fund (LFN) as a Platinum member to drive the development of open source software for the telecommunication market. Existing projects like ONAP,, Open Daylight as well as upcoming projects on Edge Computing and AI are important for our success.

After all, open source is about community. So, together with the worldwide open source community, we look forward to contributing to solve the greatest technology challenges around virtualization, as well as evaluating the potential to incorporate open source code into our networks. As founding member of O-RAN, we are already leading the drive to introduce more openness and flexibility into the radio access domain, and participating also in ONF for an enhanced network programmability within our infrastructure. Joining the LFN now complements Deutsche Telekom’s embrace of open source software as a key technology in our architectural vision for future networks.

The work in ONAP, together with our activities in ETSI-ZSM, will lead the industry towards a fully automated network and service management. One thing is very clear to me: Intelligent and automated networks will be the critical success factor to leverage the full benefits of 5G, for our customers, both consumers and verticals. And we believe in joining forces with partners in the industry to bring in innovation and accelerate the path to this shared future!

Greg Kroah-Hartman on Linux, Security, and Making Connections at Open Source Summit

Open Source Summit

Greg Kroah-Hartman talks about the importance of community interaction, and the upcoming Open Source Summit.

People might not think about the Linux kernel all that much when talking about containers, serverless, and other hot technologies, but none of them would be possible without Linux as a solid base to build on, says Greg Kroah-Hartman.  He should know. Kroah-Hartman maintains the stable branch of the Linux kernel along with several subsystems.  He is also co-author of the Linux Kernel Development Report, a Fellow at The Linux Foundation, and he serves on the program committee for Open Source Summit.

In this article, we talk with Kroah-Hartman about his long involvement with Linux, the importance of community interaction, and the upcoming Open Source Summit.

The Linux Foundation: New technologies (cloud, containers, machine learning, serverless) are popping up on weekly basis, what’s the importance of Linux in the changing landscape?

Greg K-H: There’s the old joke, “What’s a cloud made of? Linux servers.” That is truer than most people realize. All of those things you mention rely on Linux as a base technology to build on top of.  So while people might not think about “Linux the kernel” all that much when talking about containers, serverless and the other “buzzwords of the day,” none of them would be possible without Linux being there to ensure that there is a rock-solid base for everyone to build on top of.  

The goal of an operating system is to provide a computing platform to userspace that looks the same no matter what hardware it runs on top of.  Because of this, people can build these other applications and not care if they are running it locally on a Raspberry Pi or in a cloud on a shared giant PowerPC cluster as everywhere the application API is the same.

So, Linux is essential for all of these new technologies to work properly and scale and move to different places as needed.  Without it, getting any of those things working would be a much more difficult task.

LF: You have been involved with Linux for a very long time. Has your role changed within the community? You seem to focus a lot on security these days.

Greg K-H: I originally started out as a driver writer, then helped write the security layer in the kernel many many years ago.  From there I started to maintain the USB subsystem and then co-created the driver model. From there I ended up taking over more driver subsystems and when the idea for the stable kernel releases happened back in 2005, I was one of the developers who volunteered for that.

So for the past 13 years, I’ve been doing pretty much the same thing, not much has changed since then except the increased number of stable trees I maintain at the same time to try to keep devices in the wild more secure.

I’ve been part of the kernel security team I think since it was started back in the early 2000’s but that role is more of a “find who to point the bug at” type of thing.  The kernel security team is there to help

take security problem reports and route them to the correct developer who maintains or knows that part of the kernel best.  The team has grown over the years as we have added the people that ended up getting called on the most to reduce the latency between reporting a bug and getting it fixed.

LF: We agree that Linux is being created by people all over the map, but once in a while it’s great to meet people in person. So, what role does Open Source Summit play in bringing these people together?

Greg K-H: Because open source projects are all developed by people who work for different companies and who live in different places, it’s important to get together when ever possible to actually meet the people behind the email if at all possible.  Development is an interaction that depends on trust, if I accept patches from you, then I am now responsible for those changes as well. If you disappear I am on the hook for them, so either I need to ensure they are correct, or even better, I can know that you will be around to fix the code if there is a problem.  By meeting people directly, you can establish a face behind the email to help smooth over any potential disagreements that can easily happen due to the lack of “tone” in online communication.

It’s also great to meet developers of other projects to hear of ways they are abusing your project to get it to bend to their will, or learn of problems they are having that you did not know about.  Or just learn

about new things that are being developed in totally different development groups.  The huge range of talks at a conference like this makes it easy to pick up on what is happening in a huge range of different developer communities easily.

LF: You obviously meet a lot of people during the event. Have you ever come across an incident where someone ended up becoming a contributor or maintainer because of the exposure such an event provided?

Greg K-H: At one of the OSS conferences last year, I met a college student who was attending the conference for the first time.  They mentioned that they were looking of any project ideas that someone with their skill level could help out with. At a talk later that day a new idea for how to unify a specific subsystem of the kernel came up and how it was going “just take a bunch of grunt work” to accomplish.  Later that night, at the evening event, I saw the student again and mentioned the project to them and pointed them at the developer who asked for the help. They went off to talk in the corner about the specifics that would be needed to be done.

A few weeks later, a lot of patches started coming from the student and after a few rounds of review, were accepted by the maintainer.  More patches followed and eventually the majority of the work was done, which was great to see, the kernel really benefited from their contribution.

This year, I ran into the student again at another OSS conference and asked them what they were doing now.  Turns out they had gotten a job offer and were working for a Linux kernel company doing development on new products during their summer break.  Without that first interaction, meeting the developers directly that worked on the subsystem that needed the help, getting a job like that would have been much more difficult.

So, while I’m not saying that everyone who attends one of these types of conferences will instantly get a job, you will interact with developers who know what needs to be done in different areas of their open source projects.  And from there it is almost an easy jump to getting solid employment with one of the hundreds of companies that rely on these projects for their business.

LF: Are you also giving any talks at Open Source Summit?

Greg K-H:  I’m giving a talk about the Spectre and Meltdown problems that have happened this year.  It is a very high-level overview, going into the basics of what they are, and describing when the many different variants were announced and fixed in Linux.  This is a new security type of problem that is going to be with us for a very long time and I give some good tips on how to stay on top of the problem and ensure that your machines are safe.

Call for Code: Developing for Preparedness and Resilience

Call for Code

Todd Moore, Vice President Open Technology, IBM, speaks about the Call for Code initiative.

Open source is about community. At IBM, we have a commitment to open source and our developers are passionate about contributing back to open source. I’ve had the privilege to work with organizations like The Linux Foundation, Cloud Native Computing Foundation, Node.js Foundation, JS Foundation, Cloud Foundry Foundation, and many others. I’ve witnessed firsthand the power of communities to come together to grow an ecosystem, develop technology, and accelerate innovation. There’s also a human part to open source – a collective responsibility that we have to the world. There is work we can do that goes beyond developing platforms to grow our businesses and solve technical challenges. We can do more by focusing our combined developers, who already work together in open source, on critical problems that face humanity.

David Clark Cause is a company that creates purpose based initiatives and brings stakeholders together to tackle a common cause. Last year, David Clark Cause came to us with an opportunity to rally developers around a common cause and have a lasting impact.  We’ve done work like this before – for example, our IBM Foundation is working with the Open Medical Records (OpenMRS) project to create an oncology suite for use in countries in Africa and other regions using this open technology. The IBM Corporate Citizenship Office has helped deploy software from the Sahana Foundation’s open source disaster management solutions in over a dozen countries.

Given 2017 was one of the worst years on record for natural disasters, we decided to focus the efforts of 22 million developers around the world on this cause through the Call for Code initiative. David Clark Cause gave us the inspiration, and other partners like the United Nations, the American Red Cross, and The Linux Foundation came together to pool our collective efforts. Since 2000, natural disasters have directly affected 2.5 billion people, with 1.5 trillion in economic impact since 2003. And over the last 30 years, flooding is up over 240%. As developers, we can help people be more prepared, help them during a natural disaster, and help them recover afterward. We can make communities more resilient together.

Call for Code judges include iconic developers like Linus Torvalds and Tim Berners-Lee. The winning team and two semifinalists will receive support from The Linux Foundation to host their submission as an open source project and build a community around it, ensuring that it is deployable around the world in the areas of greatest need.

Xen Project Hypervisor 4.11 Brings Cleaner Architecture to Hypervisor Core Technologies

Latest release adds PVH functionality for better security and performance

SAN FRANCISCO, July 10, 2018 – The Xen Project, hosted by The Linux Foundation, today announced the release of Xen Project Hypervisor 4.11. The latest release adds new PVH-related functionality to simplify the interface between the Xen Project Hypervisor/Support and operating systems bringing added security and performance. The release also contains mitigations for the Meltdown and Spectre vulnerabilities.

The Xen Project Hypervisor is used by more than 10 million users, and powers some of the largest clouds in production today, including Amazon Web Services, Tencent, Alibaba Cloud, Oracle Cloud and IBM SoftLayer. It is the base for commercial virtualization products from Citrix, Huawei, Inspur and Oracle, and security solutions from Qubes OS, Bromium vSentry, A1Logic, Bitdefender, Star Lab’s Crucible Hypervisor, Zentific and Dornerwork’s Virtuosity.

Long-term development goals of the Xen Project continue to focus on less code, a smaller trusted computing base (TCB), less complexity, ease of maintenance, and better performance as well as scalability. To support these goals, the Xen Project has re-architected the Hypervisor’s core technologies, which encompass all core functionality, such as x86 support, device emulation and boot sequence. The latest PVH-related functionality in Xen Project 4.11 is a manifestation of this re-architecture.

“The Xen Project community worked swiftly to address the security needs of Spectre and Meltdown, and continued to match its goals in adding significant features to this release,” said Lars Kurth, chairperson of the Xen Project Advisory Board. “The latest features in this release around PVH functionality bring better security, performance and management to the Hypervisor.”

PVH Dom0 Reduces the Attack Surface of Xen Project Based Systems
PVH combines the best of PV and HVM mode to simplify the interface between operating systems with Xen Project Support and the Xen Project Hypervisor and to reduce the attack surface of Xen Project Software. PVH guests are lightweight HVM guests that use hardware virtualization support for memory and privileged instructions. PVH does not require QEMU.

Xen Project 4.11 adds experimental PVH Dom0 support by calling Xen via dom0=pvh on the command line. Running a PVH Dom0 removes approximately 1 million lines of QEMU code from Xen Project’s computing baseshrinking the attack surface of Xen Project based systems.

Enabling a PVH Dom0 requires a PVH Dom0 capable Linux or FreeBSD. Patches for each operating system are currently being upstreamed and should be available in the next Linux and FreeBSD versions.

PV in PVH container (PVH Shim) Simplifies Management
Xen Project Hypervisor 4.11 supports unmodified legacy PV-only guest to run in PVH mode. This allows cloud providers to support old, PV-only distros while only providing support for a single kind of guest (PVH) simplifying management, reducing the surface of attack significantly, and eventually allowing end-users to build a Xen Project hypervisor configuration with no “classic” PV support at all.

PCI config space emulation in Xen
Support for the PCI configuration space has been moved from QEMU to the hypervisor. Besides enabling PVH Dom0 support, this code will eventually be available to HVM guests and PVH guests. Additional security hardening needs to be performed before exposing this functionality to security supported guest types, such as PVH or HVM guests.

Mitigations against Cache Side Channel Attacks from Meltdown and Spectre
This release contains mitigations forMeltdown and Spectre vulnerabilities, including:

  • Performance optimized XPTI: Xen Project’s equivalent to Kernel page-table isolation (KPTI). Only “classic PV” guests need XPTI whereas HVM and PVH cannot attack the hypervisor via Meltdown.
  • Branch Predictor Hardening:For x86 CPUs, a new framework for Intel and AMD microcode was added related to Spectre mitigations as well as support for Retpoline.

Contributions for this release of the Xen Project came from Amazon Web Services, AMD, Arm, Citrix, DornerWorks, EPAM Systems, Gentoo Linux, Google, Huawei, Intel Corporation, Invisible Things Lab, Oracle, Qualcomm, SUSE, and a number of universities and individuals. See full list of participants in this release here.

Additional Technical Features

Scheduler Optimizations: Credit1 and Credit2 scheduling decisions when a vCPU is exclusively pinned to a pCPU or when soft-affinity is used are performance optimized.

Add DMOPs to allow use of VGA with restricted QEMU (x86): Xen Project Hypervisor 4.9 introduced the Device Model Operation Hypercall (DMOPs), which significantly limits the capability of a compromised QEMU to attack the hypervisor. In Xen 4.11 we added DMOPs that enable the usage of the VGA console, which was previously restricted.

Enable Memory Bandwidth Allocation in Xen ((Intel® Xeon® Scalable platform or Newer): Support for Memory Bandwidth Allocation (MBA) allows Xen Project Hypervisor 4.11 to slow misbehaving VMs by using a credit-based throttling mechanism.

Emulator enhancements (x86):Support for previously unsupported Intel® Advanced Vector Extensions (Intel® AVX and AVX2), and for AMD F16C, FMA4, FMA, XOP and 3DNow! instructions have been added to the x86 emulator.

Guest resource mapping (x86): Support for directly mapping Grant tables and IOREQ server pages have been introduced into Xen Project Hypervisor 4.11 to improve performance.

Clean-up and future-proofing (Arm):Xen’s VGIC support has been re-implemented. In addition, stage-2 page table handling, memory subsystems and big.LITTLE support have been refactored to make it easier to maintain and update the code in future.

Support for PSCI 1.1 and SMCCC 1.1 compliance (Arm):Xen Project is updated to comply with the latest versions of the Arm® Power State Coordination Interfaceand Secure Monitor Call Calling Conventions that provides an optimised calling convention and optional, discoverable support for mitigating Spectre Variant 2.

Comments from Xen Project Users and Contributors:

“The Xen Project Hypervisor 4.11 builds on its maturity and flexibility as a dependable, secure, type-1 hypervisor. Xen Project 4.11’s support for PVH dom0, added to its existing PVH domU capability, allows it to take advantage of the performance and scalability benefits of paravirtualization, while reducing complexity and code size, making it easier to maintain, enhance and secure,” said James Bulpin, Senior Director of Technology at Citrix. “With several other performance, security and maintainability enhancements, Xen Project 4.11 demonstrates the community’s dedication to making Xen the best hypervisor for a wide range of use-cases from huge private clouds to embedded systems.”

“Intel is pleased to see the Xen Project 4.11 release with the latest Intel-based platform features,” said Arjan Van De Ven, Intel Fellow and Director of Core Systems and Linux Pathfinding Engineering at Intel’s Open Source Technology Center. “We remain focused on enabling the best of Intel architecture to help ensure customers can take advantage of the newest features.””The Xen Project Hypervisor is an important part of the virtualization solutions SUSE provides to our customers. This newest release of Xen 4.11 offers some important benefits such as increased performance and hardening – which are critical in enterprise environments,” said Mike Latimer, Senior Engineering Manager, SUSE. “The Xen Project is an excellent example of our commitment to provide the best quality software to our customers. We look forward to continuing our contributions to this thriving community, and being a part of the exciting future of virtualization.”

OpenSDS Aruba Release Unifies SDS Control for Kubernetes and OpenStack

OpenSDS Aruba unifies storage control for Kubernetes and OpenStack in a single storage platform, offering end-users data replication using host-based or storage-based replication

SAN FRANCISCO – July 6, 2018 –The OpenSDS community has announced the release of Aruba, the first version of its open source software for SDS control. Featuring improved ease of use and a new GUI, OpenSDS Aruba added support for Kubernetes and OpenStack, enabling storage to be provisioned and managed for both containers and cloud with a single storage controller. The new OpenSDS dashboard enhances the user experience for both administrators and service users.

Remote data replication is one of the most requested features in OpenSDS, and Aruba delivers both host-based as well as storage-based replication. Host-based replication uses DRBD, an open source high-availability data replication technology contributed by Linbit, which joined OpenSDS recently. Storage-based replication leverages the data replication capabilities of storage systems; the initial reference implementation is based on Huawei Dorado V3 All-Flash Storage System, which offers an active-active solution for mission critical applications.

“The OpenSDS community is focused on making storage work better for users. This is clearly evident in the Aruba release, which offers ease of use with its intuitive dashboard and support for Kubernetes and OpenStack environments,” said Steven Tan, OpenSDS TSC Chairman, and Vice President & CTO of Cloud Storage Solution at Huawei. “Aruba gives users a taste of how OpenSDS empowers cloud and container environments with advanced data storage technologies such as host-based and storage-based data replication.”

“OpenSDS brings policy based, self-service storage provisioning and orchestration, not only ideal for cloud native applications, but also well-suited to traditional datacenters and clouds. We are continuously working with various large customers to identify their pain points and address them in an open manner,” said Rakesh Jain, Vice-Chair of the OpenSDS TSC, and Senior Architect and Researcher at IBM. “The Aruba release is a big step in this direction. We are well on our way to execute on the published roadmap to make storage as pain free as possible, in coordination with other open source projects.”

“Our private cloud system is getting bigger and bigger as our business continues to grow. We believe OpenSDS will help us reduce storage complexity and achieve our goal,” said Yusuke Sato, Storage Architect at Yahoo! JAPAN. “We welcome the release of OpenSDS Aruba, which is a first step in enabling our cloud storage platform to integrate and manage large amounts of data in our infrastructure. We expect that more and more vendors and users will join OpenSDS and the community will continue to evolve.”

“The Aruba release includes an initial implementation of multi-tenant and open storage provisioning functions that can work in conjunction with OpenStack/Kubernetes, which is essential for supporting our customers’ various use cases,” said Shoichiro Henmi, Director of Storage Infrastructure of Technology Development at NTT Communications. “I expect more and more application developers, cloud service providers and storage vendors will get involved in the OpenSDS project.”

An international community, comprising storage vendors and users, contributed to OpenSDS Aruba. The current release reflects the real-life requirements of the core members of the OpenSDS EUAC (End-User Advisory Committee). Arubais available for testing immediately.

Join Forces Against Natural Disasters with the Call for Code

The Call for Code initiative aims to harness the collective power of the global open source developer community against the growing threat of natural disasters. According to IBM, “the goal is to develop technology solutions that significantly improve disaster preparedness, provide relief from devastation caused by fires, floods, hurricanes, tsunamis and earthquakes, and benefit Call for Code’s charitable partners — the United Nations Human Rights Office and the American Red Cross.”

In a recent webcast — How 22M Developers Take on Disaster Preparedness — Mary Glackin, SVP of Science & Forecast at The Weather Company and IBM Business, spoke with representatives from participating organizations about the initiative and some of the specific goals it aims to achieve.

The Call for Code is “encouraging the global community of developers to stand up for the rights of others,” said Laurent Sauveur, Chief of External Relations, UN Human Rights.   

“It’s an exciting cause and it’s a meaningful one,” said Trishan de Lanerolle, Program Manager, Networking at The Linux Foundation, which will host the code developed through this initiative.

Additionally, Linus Torvalds, the creator of Linux and Git, will join a panel of technologists to evaluate submissions. Once complete, the winning solution will be deployed in the real world. Angel Diaz, VP Developer, IBM, explained that The Linux Foundation will host the code under the Apache 2.0 license, which will allow the code to evolve and improve even beyond the scope of this contest.

Practical Solutions

“Technology can be a wonderful and very powerful force for good,” said Sauveur, and it can improve things like tracking of aid delivery and communication in crisis situations to help pinpoint areas of need.

Getting people what they need, when they need it, and where they need it to alleviate suffering is key, said Brad Kieserman, Vice President of Disaster Cycle Services American Red Cross. And, the science of where is critical: where is the damage, where are the resources, where do they need to be?

Predictive analytics are at the center of this practice, said Kieserman, to help visualize data relating to the movement of people and resources.  “As models of service delivery improve, we can better understand the need and increase efficiency.”

Ben Narasin, Venture Partner, New Enterprise Associates offered tips for approaching the development challenge. When building such solutions, he said, it’s important to consider scale.  You need an idea that can scale, you need to build code that can scale, and you need to look at building a team that can scale.

“You cannot look at this from the perspective of ‘I have a cool technology that I want to deploy that will solve this problem.’” said de Lanerolle. “You have to think about your product being used in resource-poor environments.” For example, you have to consider things like connectivity and battery life and how to get your data at the end of the day. Such last mile challenges are critical, but open source can help.

Don’t reinvent the wheel, said de Lanerolle. “Take the opportunity to look at what’s out there.” He suggests looking at “existing technologies that are backed by open source projects where you can build resources that are available for everybody rather than just building out a one-time solution.”

Commit to the Cause

If you’re a coder, sign up, and if you’re interested, spread the word, said Glackin. “We can all be involved. Let’s all answer the call for code and make a difference in the world.”

We invite you to amplify the initiative and join the call. You can learn more about the Call for Code and watch the complete webcast here:
