How and Why to Link WebAssembly Modules

Friday 13th of August 2021 08:55:27 PM

By Marco Fioretti

WebAssembly, or Wasm for brevity, is a Web-optimized executable software format, designed to give programmers the greatest possible flexibility. Wasm binary modules can be compiled once, and then safely run anywhere, alone or embedded in other applications. In practice, Wasm needs at least three key components to keep that promise. Two of them, already presented in this series, are the WebAssembly System Interface (WASI), and Wasm Interface Types.

WASI gives Wasm modules standard, language-independent ways to interact with any host environment in which they may land. The Interface Types, instead, are equally standardized definitions, but for all kinds of software variables. By using them, Wasm modules can pass complex data structures to each other without risking corrupting them, even if they were written by independent programmers in very different source languages. The other main piece of this puzzle is called module linking. This is what allows distinct binary files to interact directly – for example using each other’s functions – as if they were both written as different sections of the same source code and then compiled together.

The pros and cons of linking Wasm modules

The first reason to link Wasm modules is one that is always valid in every area of programming, which is reuse. If a library of, say, mathematical or networking functions can be written (and maintained!) once, but in a way that allows thousands of programmers to use it with little or no effort, everybody wins.

The other reason is even simpler, but particularly important for a format like Wasm: speed. At least for the foreseeable future, most Wasm modules will be downloaded by some remote server, possibly on a slow mobile link, to be executed on the fly. In all such cases, every extra second spent downloading and preparing code can make a difference. If a large Wasm application is split in separate, interlinkable modules, its host can download only the ones its own users need, and only when they actually need them. To further reduce downloads, frequently requested modules can even be cached locally.

Of course, there can be too much of a good thing. Using many modules, especially from many independent sources, speeds up software development, but can make its maintenance more complex in the long run. At the same time, on any stable network, downloading and linking several modules takes, almost by definition, more time than getting just one blob of code that does exactly the same thing. In addition, function calls between linked Wasm modules “can be slower than function calls within one module”. Overall, all these factors may lead to a real-world performance hit of a few percentage points. In many cases, this will be a very reasonable price to pay.

The Wasm way to link modules

Independently developed Wasm modules can always be “linked” in the same way used for countless software applications, which is at compile time. This produces one executable file that has all the desired features and is ready to run inside any Wasm/WASI compliant virtual machine. Besides depending on the specific languages and toolchain used to generate each executable file, however, this static linking is almost the opposite of the desired result: a “portable, host- and language-independent ecosystem” of WebAssembly modules that are composable as needed after, not before downloading them, and regardless of where they came from.

A first, if small step in this direction consists of using the already mentioned Wasm Interface Types: they can, in fact, let different Wasm modules exchange copies of their data structures, without actually sharing them but as if they were parts of the same program. This limited form of cooperation among modules is called “Shared-Nothing Linking”.

The kind of linking that is really consistent with the core Wasm philosophy, however, is the one that happens only when and where it is really needed, does not waste resources and, above all, doesn’t put unnecessary constraints on the providers of Wasm modules. The linking, that is, should happen on the host that actually needs it, but without requiring any preparation for the modules that are linked, or any application-specific customization for the programmers who wrote them.

This means that Wasm binaries should use some virtualization technique to declare and import the other modules (or parts of them) that they want to link. This mechanism, called “link-time virtualization” would eventually allow so-called “Shared-Everything Dynamic Linking”, in which all the linked modules could directly share their memory and data tables, without duplications. The low-level, gory details of this approach are described in the corresponding section of the official Explainer for linking Wasm modules linking. Here, we only mention two of the general properties, or constraints, that every “pure-Wasm” linking solution should include.

The first one is the “Principle of Least Authority”, by which every Wasm module must always expose to its host, or demand from it, only the smallest possible subset of capabilities that it needs to do its job. The other is, to put it simply, that linking modules should not make Garbage Collection in Wasm more complicated than it already is.

In practice: Emscripten, JavaScript APIs and WAPM

The most elementary tools to create and use from scratch linked Wasm modules are functions like dlopen() in C or C++ or, in JavaScript, the equivalent WebAssembly APIs. With the proper instructions, the Emscripten toolchain can add, to the glue logic that makes JavaScript virtual machines load and run Wasm code, a dynamicLibraries array that lists all the modules that should be downloaded and then linked. To study or use complete linkable modules instead, check out the official registry of the WebAssembly Package Manager (WAPM), an open source tool whose purpose is exactly to facilitate the publication and installation of such modules.

Facebook, Google, Isovalent, Microsoft and Netflix Launch eBPF Foundation as Part of the Linux Foundation

Thursday 12th of August 2021 10:48:01 PM

Industry leaders come together to drive the growth of eBPF as a transformational technology to redefine networking, security, tracing and observability

SAN FRANCISCO, August 12, 2021 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced that it is hosting the eBPF Foundation. Founding members include Facebook, Google, Isovalent, Microsoft and Netflix. This comes in advance of the eBPF Summit, a free and virtual event taking place August 18-19, 2021.

eBPF allows developers to safely and efficiently embed programs in any piece of software, including the operating system kernel. As a result, eBPF is quickly becoming the method of choice for achieving a wide range of infrastructure use cases, delivering significant efficiency and performance gains and dramatically reducing the complexity of the system. For example, Facebook is using eBPF as the primary software-defined load balancer in its data centers, and Google is using Cilium to bring eBPF-based networking and security to the managed Kubernetes offerings GKE and Anthos.

“eBPF is a revolutionary technology that allows us to modify operating system behavior in real time without risky or expensive kernel code changes. It’s had a remarkable impact on our ability to iterate quickly on everything from networking to security to containerization,” said Alexei Starovoitov, Co-creator and Maintainer of eBPF, Kernel Developer at Facebook.

eBPF changes the way operating systems and infrastructure services are designed. It bridges the boundary between kernel and user space. It encourages and accelerates innovation and is a significant leap forward in open source technology for networking, security, application profiling/tracing and system observability use cases. eBPF enables users to even combine and apply logic across multiple subsystems which were traditionally completely independent.

“eBPF has redefined the way we think about the operating system and has led to a massive wave of innovation in networking, security, and observability. Because of its deep relevance in the cloud native world, eBPF adoption has been accelerating at an incredible pace,” said Daniel Borkmann, Co-creator and Maintainer of eBPF, Kernel Developer at Isovalent.

By making the OS kernel programmable, infrastructure software can leverage existing layers, making them more intelligent, scalable and feature-rich without continuing to add additional layers of complexity to the system. eBPF has resulted in the development of a completely new generation of tooling in areas such as networking, security, application profiling/tracing and performance troubleshooting that no longer rely on existing kernel functionality but instead actively reprogram runtime behavior without compromising execution efficiency or safety.

The eBPF Foundation will expand the significant level of contributions being made to extend the powerful capabilities of eBPF and grow beyond Linux. It will be the home for open source eBPF projects and technologies and nurture the community through a variety of activities, including summits and other collaboration events in order to further drive the growth and adoption of the eBPF ecosystem.

“eBPF is one of the greatest examples of the kind of innovation that happens in the Linux community and encompasses technologies that are natural for us to host. It also represents the future of operating systems and microservices delivery,” said Mike Dolan, general manager and senior vice president of projects at the Linux Foundation. “We look forward to supporting the work of the eBPF Foundation and community.”

Funded open source security work at the Linux Foundation

Tuesday 10th of August 2021 11:00:00 PM

Open source software (OSS) is vitally important to the functioning of society today; it underpins much of the global economy. However, some OSS is highly secure, while others are not as secure as they need to be.

By its very nature, open source enables worldwide peer review, yet while its transparency has the potential for enhanced software security, that potential isn’t always realized. Many people are working to improve things where it’s needed. Most of that work is done by volunteers or organizations outside the Linux Foundation (LF) who directly pay people to do the work (typically as employees). Often those people work together within a foundation that’s part of the Linux Foundation. Sometimes, however, the LF or an LF foundation/project (e.g., a fund) directly funds people to do security work.

At the Linux Foundation (LF), I have the privilege of overseeing focused work to improve OSS security by the very people paid to do it. This work is funded through various grants and foundations, with credits to organizations like Google, Microsoft, the Open Source Security Foundation (OpenSSF), the LF Public Health foundation, and the LF itself.

The LF and its foundations do much more that I don’t oversee, so I’ve only listed the ones I am personally involved with in the interest of brevity. I hope it will give you a sense of some of the things we’re doing that you might not know about otherwise.

The typical LF oversight process for this work is described in “Post-Approval LF Security Funding.” Generally, performers must provide a periodic summary of their work so they can get paid. Most of those summaries are public, and in those cases, it’s easy for others to learn about their interesting work!

Here’s a sample of the work I oversee:

Ariadne Conill is improving Alpine Linux security, including significant improvements to its vulnerability processing and making it reproducible. For example, as noted in the July 2021 report, this resulted in Alpine 3.14 being released with the lowest open vulnerability count in the final release in a long time. Alpine Linux’s security is important because many containers use it. For more information, see “Bits relating to Alpine security initiatives in June” and “Bits relating to Alpine security initiatives in July.”kpcyrd is doing a lot of reproducible build work on Linux distributions, especially Alpine Linux (including on the Raspberry Pi) and Arch Linux. Reproducible builds are a strong countermeasure against build system attacks (such as the devastating attack on SolarWinds Orion). More than half of the currently unreproducible packages in Arch Linux have now been reviewed and classified.David Huseby has been working on modifying git to have a much more flexible cryptographic signing infrastructure. This will make it easier to verify the integrity of software source code; git is widely used to manage source code.Theo de Raadt has also been receiving funding to secure the critical “plumbing” behind modern communications infrastructure:This funding is being used towards improving OpenSSH (a widely-used tool whose security is critical). These include various smaller improvements, an updated configuration file parser, and a transition to using the SFTP protocol rather than the older RCP protocol inside the scp(1) program.It is also being used to improve rpki-client, implementing Resource Public Key Infrastructure (RPKI). RPKI is an important protocol for protecting the Internet’s routing protocols from attack. These improvements implement the RPKI Repository Delta Protocol (RRDP) data transfer protocol and fix various edge cases (e.g., through additional validation checks). The https://irrexplorer.nlnog.net/ service is even using rpki-client behind the scenes.

Nathan Chancellor is improving the Linux kernel’s ability to be compiled with clang (instead of just gcc). This includes eliminating warning messages from clang (which helps to reduce kernel bugs even when gcc is used) and fixing/extending the clang compiler (which helps clang users when compiling code other than the Linux kernel). Unsurprisingly this involves changing both the Linux kernel and the clang/LLVM compiler infrastructure, and sometimes other software as well.In the long run, eliminating warnings that by themselves aren’t bugs is important; developers will ignore warnings if there are many irrelevant ones, but if there are only a few warnings, they’ll examine them (making warnings more useful).Of notable mention for security implications is clang support for Control-Flow Integrity (CFI); this can counter many attacks on arm64, and work will eventually enable x86_64 support.

I oversee some security audits conducted via the Open Source Technology Improvement Fund (OSTIF) when funded through the LF. We (the LF) often work with OSTIF to conduct security audits. We work with OSTIF to define the audit scope, and then OSTIF runs a bidding process where qualified security audit firms propose to do the work. We then work with OSTIF to select the winner (who isn’t always the cheapest — we want good work, not a box-check). OSTIF & I then oversee the process and review the final result. Note that we don’t just want to do audits, we also want to fix or mitigate any critical issues the audits identify, but the audits help us find the key problems. Subject matter experts perform the audit reports, and handling bidding is OSTIF’s primary focus, so my main contribution is usually to help ensure these reports are clear to non-experts while still being accurate. Experts sometimes forget to explain their context and jargon, and it’s sometimes hard to fix that (you must know the terminology & technology to explain it).This work included two security audits related to the Linux kernel, one for signing and key management policies and the other for vulnerability reporting and remediation. I’ve also overseen audits of the exposure notification applications COVID Shield and COVID Green: It’s not part of my oversight of OSTIF on behalf of the LF, but I also informally talk with OSTIF about other OSS they’re auditing (such as flux2, lodash, jackson-core, jackson-databind, httpcomponents-core, httpcomponents-client, laravel, and slf4j). A little coordination and advice-sharing among experts can make everything better.

The future is hard to predict, but we anticipate that we will be doing more. In late July, the OpenSSF Technical Advisory Council (TAC) recommended approving funding for a security audit of (part of) Symfony, a widely-used web framework. The OpenSSF Governing Board (GB) approved this on 2021-08-05 and I expect OSTIF will soon take bids on it.

The OpenSSF is also taking steps to raise more money via membership dues (this was delayed due to COVID; starting a new foundation is harder during a pandemic). Once the OpenSSF has more money, we expect they’ll be funding a lot more work to identify critical projects, do security audits, fix problems, and improve or create projects to enhance OSS security. The future looks bright.

Please remember that this is only a small part of ongoing work to improve OSS security. Almost all LF projects need to be secure, so most foundations’ projects include security efforts not listed here. As noted earlier, most development work is done by volunteers or by non-LF organizations directly paying people to do the work (typically employees). 

The OpenSSF has several working groups and many projects where people are working together to improve OSS security. These include free courses on how to develop secure software and the CII Best Practices badge project. We (at the LF) also have many other projects working to improve OSS security. For example, sigstore is making cryptographic signatures much easier; sigstore’s “cosign” tool just released its version 1.0. Many organizations have recently become interested in software bill-of-materials (SBOMs), and we’ve been working on SBOMs for a long time.

If you or your organization would like to fund focused work on improving OSS security, please reach out! You can contribute to the OpenSSF (in general or as a directed fund); just contact them (e.g., Microsoft contributed to OpenSSF in December 2020). If you’d prefer, you can create a grant directly with the Linux Foundation itself — just email me at <dwheeler@linuxfoundation.org> if you have questions. For smaller amounts, say to fund a specific project, you can also consider using the LFX crowdfunding tools to fund or request funding. Many people & organizations struggle to pay individual OSS developers because of the need to handle taxes and oversight. If that’s your concern, talk to us. The LF has experience & processes to do all that, letting experts focus on getting the work done.

My sincere thanks to all the performers for their important work and to all the funders for their confidence in us!

Vaccines + Masks for Safe In-Person Events – Read About All On-Site Safety Protocols

Thursday 5th of August 2021 02:55:20 AM

The Linux Foundation is ecstatic to return to in-person events next month; we know how important these face-to-face gatherings are to accelerating collaboration and innovation in the open source community. 

We know you have questions surrounding health and safety at in-person events and want to pause for a moment to address these. Rest assured – your health has been at the forefront of every move and decision we have made as we make a safe return back to in-person events.  

Let’s start here with some items from behind the scenes.

The LF has a long-standing relationship with Dr. Joel Selanikio, a physician, former CDC epidemiologist and outbreak investigator, and consultant epidemiologist to the DC Department of Health and to FEMA for the COVID-19 response over 2020-21. Thanks to Dr. Selanikio’s council over the last two years, we have been able to take educated and well-thought out steps to ensure the safety of our community members as we navigate COVID-19. We are working closely with local Departments of Health to ensure we are following all local requirements and recommendations. We are continuing to monitor and follow all CDC, WHO and PHE/NHS (in the UK) guidelines, in addition to those of the local municipalities in which we are holding events.We are checking in with our venues and vendors multiple times a week to ensure we are staying up-to-date on best practices and regulations.Finally, The Linux Foundation Event Team have all been certified in handling Pandemic On-Site Protocols (by the Event Leadership Institute). The team is vaccinated, trained and equipped to handle safety protocols and procedures at our events and are more than happy to assist you onsite and ensure you are comfortable.  

Vaccines, masks and everyone’s new favorite phrase: social distancing.

As announced previously, in-person attendees will be required to be fully vaccinated against the COVID-19 virus. A vaccine verification app will be used to confirm vaccination status.Additionally, masks will now be required for in-person attendance.All event participants will receive a daily temperature check in order to enter the event zone and will receive a sticker to be able to enter and exit as needed.Comfort level wristbands (in green, yellow, and red) will be provided for event participants to use if they choose to indicate their preference on social distancing comfort level. 

All of the above protocols are in place for LF and LF Project events (like KubeCon + CloudNativeCon) through November 2021.

We are working closely with each of our venues and their local jurisdictions to ensure we are following all local requirements and recommendations. Here are some items you can expect on-site at any of our events through November:

Reduced conference room capacity: space between you and your neighbors.More physical space between speakers and attendees: so speakers can present without their masks (and you can hear them clearly!).Wider aisles and thoroughfares through event spaces.Sponsor booths spread further apart in the exhibit hall as well as wider aisles. Socially distanced areas for eating/drinking and mask breaksClose organization with venues: to ensure rigorous onsite cleaning and sanitizing of all touch points, sneeze guards where necessary, and sanitation stations.

You can view a full list of onsite safety procedures on the Health and Safety page, under the “Attend” tab on all event microsites at events.linuxfoundation.org.

Quick Links

View KubeCon + CloudNativeCon Health and Safety page

We are keeping our health and safety guidelines updated regularly, and adding to the FAQ as necessary.  If these resources do not answer a question you may have, reach out to us at events@linuxfoundation.org.

After much research and with guidance from Dr. Selanikio, we believe the combination of vaccination and mask requirements, along with the other protocols we are putting in place, provides a safe environment for our in-person event participants.

We understand that not everyone will be able to join us in-person due to a variety of factors, which is why we are delighted to offer attendees the ability to participate in our events virtually. To learn more about the different pass options, click on the “Register” tab on any of our event websites.

We hope this information brings you assurance that keeping you and all our event participants safe is top of mind – and will continue to be as we make each and every decision. A big THANK YOU to the entire open source community for your understanding during this fluid COVID-19 situation and this very challenging time in our history. We look forward to seeing you at our events this fall!

Success Story: Preparing for Kubernetes Certification Improves a Platform Development Engineer’s Skills

Thursday 29th of July 2021 09:00:47 PM

Faseela K. is a platform development engineer with a background in open source networking. As she saw the use of containers growing more than the VMs she was working with, she began studying Kubernetes and eventually decided to pursue a Certified Kubernetes Administrator (CKA). We spoke to her about her experience.

Linux Foundation: What was the experience like taking the CKA exam?

Faseela K: I was actually nervous, as this was the first online certification exam I was taking from home, so there was some uncertainty going in. Would the proctor turn up on time? Will the cloud platform where we are taking the exam get stuck? Will I be able to finish the exam on time? Those and several other such questions ran through my mind. But I turned down all my concerns, had a very smooth exam experience, and was able to finish it without any difficulties. 

LF: How did you prepare for the exam?

FK: I am a person who uses Kubernetes in my day to day work, so the topics in the syllabus were familiar to me. On top of that I did some practice tests and online courses. Preparing for the exam made so many of my day to day work related tasks much easier, and my level of expertise on K8s increased considerably.

LF: How did preparing for and taking CKA help you improve your skills?

FK: Though I work on K8s regularly, the range of concepts and capabilities I was using were minimal. Preparing for CKA helped me touch upon all areas of K8s, and the experience which I already had helped me get a complete end to end view of things. I can troubleshoot Kubernetes issues in a better way now, and go deep into each problem to find a solution.

LF: Tell us more about your current job role. What types of activities are you engaged in and how has the CKA helped with them?

FK: I currently work as a platform development engineer at Cisco, where we develop and maintain an enterprise Kubernetes platform. Troubleshooting, upgrading, networking, and system management of containerized platforms are part of our daily tasks, and CKA has helped me master all these areas with perfection. The training which I took to prepare for the CKA phenomenally transformed my perspective about Kubernetes administration, and this has helped me attain an end to end view of the product. Debugging any issues in the platform has become easier than ever, and the certification has given me even more confidence with fixing issues in a time sensitive manner.

LF: You mentioned to us previously you’d like to take the Certified Kubernetes Application Developer (CKAD) next; what appeals to you about that certification?

FK: I am planning to go deeper into containerized application development in my career, and hence CKAD was appealing to me. In fact, I already completed CKAD and became CKAD certified within less than a month of achieving my CKA certification. The confidence I gained after CKA helped me try the second one also faster.

LF: Tell us about your experience working on the OpenDaylight project. What prompted you to move from focusing on SDN to Kubernetes?

FK: I was previously a member of the Technical Steering Committee of the OpenDaylight project at The Linux Foundation, and made a lot of contributions to OpenDaylight. Working in open source has been the most amazing experience I have ever had in my life, and OpenDaylight gave me exposure to the various activities under LF Networking, while being a part of The Linux Foundation generally helped me engage with some of the top notch brains across organizations. 

Coming together from across the globe during various conferences and DDFs, and working together across the company boundaries to solve common SDN problems has given me so much satisfaction. Over a period of time, containers were gaining traction over VMs, and I wanted to get more involved with containerization and platform development, where Kubernetes looked more promising.

LF: What are your future career goals?

FK: I intend to learn more about K8s internal implementation, and also to get involved with projects like istio, servicemesh and networkservicemesh in the future. My dream is to become a cloud native software developer, who promotes containerized application development in a cloud native way.

LF: What technology are you most interested in studying next?

FK: I am currently pursuing a course on the golang programming language. I also plan to take the Certified Kubernetes Security Specialist (CKS) exam if time permits.

5 open source tabletop RPGs you should try

Open source arrived in the pen-and-paper RPG industry back at the turn of the century, when Wizards of the Coast, publisher of Magic: The Gathering and Dungeons & Dragons, developed the Open Game License (OGL). Many publishers have since adopted the OGL themselves or use similar licenses, such as Creative Commons. Today is Free RPG Day. It's the one day a year you can go to your friendly local game store and pick up, at no cost, a free tabletop role-playing game from some of the biggest publishers in the hobby. If you don't have a local game store or can't get out to a game store, some free RPG sampler downloads are available from Dungeon Crawl Classics and Paizo.
