Announcing coreboot 4.14

Tuesday 11th of May 2021 04:36:10 PM
The coreboot firmware project has released version 4.14. "These changes have been all over the place, so that there's no particular area to focus on when describing this release: We had improvements to mainboards, to chipsets (including much welcomed work to open source implementations of what has been blobs before), to the overall architecture."

Two stable kernels

Tuesday 11th of May 2021 03:32:30 PM
Stable kernels 5.10.36 and 5.4.118 have been released. They both contain important fixes throughout the tree. Users should upgrade.

[$] The second half of the 5.13 merge window

Monday 10th of May 2021 08:30:53 PM
By the time the last pull request was acted on and 5.13-rc1 was released, a total of 14,231 non-merge commits had found their way into the mainline. That makes the 5.13 merge window larger than the entire 5.12 development cycle (13,015 commits) and just short of all of 5.11 (14,340). In other words, 5.13 looks like one of the busier development cycles we have seen for a little while. About 6,400 of these commits came in after the first-half summary was written, and they include a number of significant new features.

Security updates for Monday

Monday 10th of May 2021 03:13:35 PM
Security updates have been issued by Debian (libxml2), Fedora (autotrace, babel, kernel, libopenmpt, libxml2, mingw-exiv2, mingw-OpenEXR, mingw-openexr, python-markdown2, and samba), openSUSE (alpine, avahi, libxml2, p7zip, redis, syncthing, and vlc), and Ubuntu (webkit2gtk).

Kernel prepatch 5.13-rc1

Monday 10th of May 2021 02:04:29 AM
The first 5.13 kernel prepatch is out for testing, and the merge window is closed for this development cycle. "This was - as expected - a fairly big merge window, but things seem to have proceeded fairly smoothly. Famous last words." In the end, 14,231 non-merge changesets were pulled into the mainline during the merge window — more than were seen during the entire 5.12 cycle.

An IEEE statement on the UMN paper

Friday 7th of May 2021 10:31:02 PM
The IEEE, whose Symposium on Security and Privacy conference had accepted the "hypocrite commits" paper for publication, has posted a statement [PDF] on the episode.

The paper was reviewed by four reviewers in the Fall S&P 2021 review cycle and received a very positive overall rating (2 Accept and 2 Weak Accept scores, putting it in the top 5% of submitted papers). The reviewers noted that the fact that a malicious actor can attempt to intentionally add a vulnerability to an open source project is not new, but also acknowledged that the authors provide several new insights by describing why this might be easier than expected, and why it might be difficult for maintainers to detect the problem. One of the PC members briefly mentioned a possible ethical concern in their review, but that comment was not significantly discussed any further at the time; we acknowledge that we missed it.

The statement concludes with some actions to be taken by IEEE to ensure that ethically questionable papers are not accepted again.

[$] Noncoherent DMA mappings

Friday 7th of May 2021 02:18:04 PM
While it is sometimes possible to perform I/O by moving data through the CPU, the only way to get the required level of performance is usually for devices to move data directly to and from memory. Direct memory access (DMA) I/O has been well supported in the Linux kernel since the early days, but there are always ways in which that support can be improved, especially when hardware adds some challenges of its own. The somewhat confusingly named "non-contiguous" DMA API that was added for 5.13 shows the kinds of things that have to be done to get the best performance on current systems.

Five new stable kernels

An Interview With Linus Torvalds: Open Source And Beyond - Part 2 (Tag1)

Friday 7th of May 2021 01:45:28 PM
The second half of the interview with Linus Torvalds on the Tag1 Consulting site has been posted.

I think one of the reasons Linux succeeded was exactly the fact that I actually did NOT have a big plan, and did not have high expectations of where things would go, and so when people started sending me patches, or sending me requests for features, to me that was all great, and I had no preconceived notion of what Linux should be. End result: all those individuals (and later big companies) that wanted to participate in Linux kernel development had a fairly easy time to do so, because I was quite open to Linux doing things that I personally had had no real interest in originally.

[$] A pair of memory-allocation improvements in 5.13

Thursday 6th of May 2021 02:23:05 PM
Among the many changes merged for 5.13 can be found performance improvements throughout the kernel. This work does not always stand out the way that new features do, but it is vitally important for the future of the kernel overall. In the memory-management area, a couple of long-running patch sets have finally made it into the mainline; these provide a bulk page-allocation interface and huge-page mappings in the vmalloc() area. Both of these changes should make things faster, at least for some workloads.

[$] A replacement for third-party cookies?

Wednesday 5th of May 2021 10:19:39 PM
The era of tracking users all across the web using third-party cookies is coming to a close; that type of cookie is something of a zombie at this point. All of the major browsers, save one, are blocking third-party cookies by default and the holdout, Google Chrome, plans to make that change next year. But Google, which has a business model built around advertising that benefits greatly from the status quo, has offered up an alternative scheme to "replace" third-party cookies. The Federated Learning of Cohorts (FLoC) is an in-browser mechanism to pigeonhole users in a way that will be useful to advertisers, but the only reason the idea has any traction at all is because it is being implemented in Chrome—the dominant browser today.

The TAB report on the UMN affair

Wednesday 5th of May 2021 05:46:43 PM
The Linux Foundation Technical Advisory Board has issued its report on the submission of (intentionally and unintentionally) buggy patches from the University of Minnesota.

This report summarizes the events that led to this point, reviews the "Hypocrite Commits" paper that had been submitted for publication, and reviews all known prior kernel commits from UMN paper authors that had been accepted into our source repository. It concludes with a few suggestions about how the community, with UMN included, can move forward.

The recommendations include establishing an internal review process for patches submitted by the community and the creation (by the TAB in cooperation with researchers) of a "best practices" document for researchers working with the kernel community.

(LWN editor Jonathan Corbet played a small part in the writing of this report).

[$] Rustls: memory safety for TLS

Tuesday 4th of May 2021 08:45:06 PM
The movement toward using memory-safe languages, and Rust in particular, has picked up a lot of steam over the past year or two. Removing the possibility of buffer overflows, use-after-free bugs, and other woes associated with unmanaged pointers is an attractive feature, especially given that the majority of today's vulnerabilities stem from memory-safety issues. On April 20, the Internet Security Research Group (ISRG) announced a funding initiative targeting the Rustls TLS library in order to prepare it for more widespread adoption—including by ISRG's Let's Encrypt project.

Excellent Utilities: duf – disk usage utility

This is a series highlighting best-of-breed utilities. We cover a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides. There’s a complete list of the tools in this series in the Summary section. The Command Line Interface (CLI) is a way of interacting with your computer. To harness all the power of Linux, it’s highly recommended mastering the interface. It’s true the CLI is often perceived as a barrier for users migrating to Linux, particularly if they’re grown up using GUI software exclusively. While Linux rarely forces anyone to use the CLI, some tasks are better suited to this method of interaction, offering inducements like superior scripting opportunities, remote access, and being far more frugal with a computer’s resources. duf is a simple disk usage utility that offers a more attractive representation than the classic df utility. It’s written in Go. Read more
