Podman can use native overlay file system with the Linux kernel versions 5.13. Up until now, we have been using fuse-overlayfs. The kernel gained rootless support in the 5.11 kernel, but a bug prevented SELinux use with the file system; this bug was fixed in 5.13.

Linux 5.13-rc7 Released Following A Very Calm Week


LINUX KERNEL --

Linus Torvalds is celebrating Father’s Day by releasing Linux 5.13-rc7. Kernel maintainers and testers managed to keep him happy the father of Linux happy this week by keeping to a small change set for this late-stage release candidate.

Torvalds wrote in the 5.13-rc7 announcement, “So we’ve had a very calm last week, and in fact if it hadn’t been for the networking side, it would have been positively tiny. Just over half the commits are from the networking tree, and honestly, though networking changes dominate, it’s not like there’s a ton of networking changes – it’s all pretty small. The two largest commits are a revert and a code movement patch for a build issue.

If this keeps up, Linux 5.13 stable could be released next Sunday without having to resort to a 5.13-rc8 that would otherwise put out the final release to 4 July.

Among the fixes added to Linux 5.13-rc7 are more fixes to the messy FPU/XSTATE code and a lot of other mostly mundane fixes.

See our Linux 5.13 feature overview to learn more about the changes in store for this summer 2021 kernel version.


Adoption of a “COVID-19 Vaccine Required” Approach for our Fall 2021 Event Line-up


After careful consideration, we have decided that the safest course of action for returning to in-person events this fall is to take a “COVID-19 vaccine required” approach to participating in-person. Events that will be taking this approach include:

Open Source Summit + Embedded Linux Conference (and co-located events), Sept 27-30, Seattle, WAOSPOCon, Sept 27-29, Seattle, WALinux Security Summit, Sept 27-29, Seattle, WAOpen Source Strategy Forum, Oct 4-5, London, UKOSPOCon Europe, Oct 6, London, UKOpen Networking & Edge Summit + Kubernetes on Edge Day, Oct 11-12, Los Angeles, CAKubeCon + CloudNativeCon (and co-located events), Oct 11-15, Los Angeles, CAThe Linux Foundation Member Summit, Nov 2-4, Napa, CAOpen Source Strategy Forum, Nov 9-10, New York, NY

We are still evaluating whether to keep this requirement in place for events in December and beyond. We will share more information once we have an update.

Proof of full COVID-19 vaccination will be required to attend any of the events listed above. A person is considered fully vaccinated 2 weeks after the second dose of a two-dose series, or two weeks after a single dose of a one-dose vaccine.

Vaccination proof will be collected via a digitally secure vaccine verification application that will protect attendee data in accordance with EU GDPR, California CCPA, and US HIPAA regulations. Further details on the app we will be using, health and safety protocols that will be in place onsite at the events, and a full list of accepted vaccines will be added to individual event websites in the coming months. 

While this has been a difficult decision to make, the health and safety of our community and our attendees are of the utmost importance to us. Mandating vaccines will help infuse confidence and alleviate concerns that some may still have about attending an event in person. Additionally, it helps us keep our community members safe who have not yet been able to get vaccinated or who are unable to get vaccinated. 

This decision also allows us to be more flexible in pivoting with potential changes in guidelines that venues and municipalities may make as organizations and attendees return to in person events. Finally, it will allow for a more comprehensive event experience onsite by offering more flexibility in the structure of the event.

For those that are unable to attend in-person, all of our Fall 2021 events will have a digital component that anyone can participate in virtually. Please visit individual event websites for more information on the virtual aspect of each event.

We hope everyone continues to stay safe, and we look forward to seeing you, either in person or virtually, this fall.

FAQ

Q:If I’ve already tested positive for COVID-19, do I still need to show proof of COVID-19 vaccination to attend in person? 

A: Yes, you will still need to show proof of COVID-19 vaccination to attend in-person.

Q: Are there any special circumstances in which you will accept a negative COVID-19 test instead of proof of a COVID-19 vaccination? 

A: Unfortunately, no. For your own safety, as well as the safety of all our onsite attendees, everyone who is not vaccinated against COVID-19 will need to participate in these events virtually this year, and will not be able to attend in-person.

Q: I cannot get vaccinated for medical, religious, or other reasons. Does this mean I cannot attend?

A: For your own safety, as well as the safety of all our onsite attendees, everyone who is not vaccinated against COVID-19 – even due to medical, religious or other reasons – will need to participate in these events virtually this year, and will not be able to attend in-person.

Q: Will I need to wear a mask and socially distance at these events if everyone is vaccinated? 

A: Mask and social distancing requirements for each event will be determined closer to event dates, taking into consideration venue and municipality guidelines.

Q: Can I bring family members to any portion of an event (such as an evening reception) if they have not provided COVID-19 vaccination verification in the app? 

A: No. Anyone that attends any portion of an event in-person will need to register for the event, and upload COVID vaccine verification into our application.

Q: Will you provide childcare onsite at events again this year?

A: Due to COVID-19 restrictions, we unfortunately cannot offer child care services onsite at events at this time. We can, however, provide a list of local childcare providers. We apologize for this disruption to our normal event plans. We will be making this service available as soon as we can for future events.

Q: Will international (from outside the US) be able to attend? Will you accept international vaccinations?

A: Absolutely. As mentioned above, a full list of accepted vaccines will be added to individual event websites in the coming months.

Free Training Course Explores Software Bill of Materials


At the most basic level, a Software Bill of Materials (SBOM) is a list of components contained in a piece of software. It can be used to support the systematic review and approval of each component’s license terms to clarify the obligations and restrictions as it applies to the distribution of the supplied software. This is important to reducing risk for organizations building software that uses open source components.

There is often confusion concerning the minimum data elements required for an SBOM and the reasoning behind why those elements are included. Understanding how components interact in a product is key for providing support for security processes, compliance processes, and other software supply chain use cases. 

This is why The Linux Foundation has taken the step of creating a free, online training course, Generating a Software Bill of Materials (LFC192). This course provides foundational knowledge about the options and the tools available for generating SBOMs and will help with understanding the benefits of adopting SBOMs and how to use them to improve the ability to respond to cybersecurity needs. It is designed for directors, product managers, open source program office staff, security professionals, and developers in organizations building software. Participants will walk away with the ability to identify the minimum elements for a SBOM, how they can be coded up, and an understanding of some of the open source tooling available to support the generation and consumption of an SBOM. 

The course takes around 90 minutes to complete. It features video content from Kate Stewart, VP, Dependable Embedded Systems at The Linux Foundation, who works with the safety, security, and license compliance communities to advance the adoption of best practices into embedded open source projects. A quiz is included to help confirm learnings.

GFX1013 Target Added To LLVM 13.0 For RDNA2 APUs


LLVM --

Merged last week to mainline LLVM 13.0 was the new “GFX1013” target for the AMDGPU shader compiler. Well, it landed twice as at first had to be reverted after breaking the build bots / sanitizer testing.

GFX1013 is the newest graphics target for AMDGPU LLVM. Notable out of the commit is confirmation that it’s for an RDNA2-based APU. Like with the other RDNA2 GPUs, the compiler target does confirm that GFX1013 does feature ray-tracing support with the BVH ray-tracing instructions being present.

Current rumors put the Ryzen 6000 series APUs as featuring Zen 3 (or Zen 3+) CPU cores with RDNA2 graphics. These “Rembrandt” APUs are also expected to launch with DDR5 memory support. Some more recent rumors put the Rembrandt APUs as having up to 12 CUs. In any case it will be great to see AMD APUs coming with RDNA2 in moving beyond Vega graphics.

The LLVM 13.0 compiler stack should be out as stable in September while waiting for the rest of the open-source AMD Radeon Linux graphics stack to get ironed out for AMD’s next-gen APUs.
