Evolving the ASF Brand (Apache Software Foundation blog)

1 év 1 hónap óta
The Apache Software Foundation (ASF) has announced that it will be changing its logo to remove the feather that has been part of its brand since 1997. ASF members will have input on the rebranding process and be able to vote on the new logo, which will be unveiled at the Community Over Code conference in October. The feather is a well-loved and iconic part of the ASF brand. We know of community members who have ASF feather tattoos. People love taking photos with the feather at our flagship event each year.

So why would we change it? As a non-Indigenous entity, we acknowledge that it is inappropriate for the Foundation to use Indigenous themes or language. We thank Natives in Tech and other members of the broader open source community for bringing this issue to the forefront. Today we are announcing we will be retiring the feather icon and logo and replacing it with a new logo that embodies the Foundation's rich history of providing software for the public good.

[$] Filesystem testing for stable kernels

1 év 1 hónap óta
Leah Rumancik led a filesystem-track session at the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit on the testing needed to qualify XFS patches for the stable kernels. At last year's summit, Rumancik, Amir Goldstein, and Chandan Babu Rajendra presented on their efforts to test and backport fixes for the XFS filesystem to three separate stable kernels. There has been some longstanding unhappiness in the XFS-development community with the stable-kernel process, which led to backports ceasing for that filesystem until Goldstein started working on XFS testing for the stable trees a few years ago. In this year's session, Rumancik updated attendees on how things had gone over the last year and wanted to discuss some remaining pain points for the process.

[$] The first half of the 6.11 merge window

1 év 1 hónap óta
The merge window for the 6.11 kernel release opened on July 14; as of this writing, 4,072 non-merge changesets have been pulled into the mainline repository since then. This merge window, in other words, is just now beginning. Still, there has been enough time for a number of interesting changes to land for the next kernel release; read on for a summary of what has been merged so far.

[$] Changing the filesystem-maintenance model

1 év 1 hónap óta
Maintenance of the kernel is a difficult, often thankless, task; how it is being handled, the role of maintainers, burnout, and so on are recurring topics at kernel-related conferences. At the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit, Josef Bacik and Christian Brauner led a session to discuss possible changes to the way filesystems are maintained, though Bacik took the lead role (and the podium). There are a number of interrelated topics, including merging new filesystems, removing old ones, making and testing changes throughout the filesystem tree, and more.

Silva: How to use the new counted_by attribute in C (and Linux)

1 év 1 hónap óta
Gustavo A. R. Silva describes the path to safer flexible arrays in the kernel, thanks to the counted_by attribute supported by Clang 18 and GCC 15.

There are a number of requirements to properly use the counted_by attribute. One crucial requirement is that the counter must be initialized before the first reference to the flexible-array member. Another requirement is that the array must always contain at least as many elements as indicated by the counter.

[$] SUSE asks openSUSE to consider name change

1 év 1 hónap óta

SUSE has, in a somewhat clumsy fashion, asked openSUSE to consider rebranding to clear up confusion over the relationship between SUSE the company and openSUSE as a community project. That, in turn, has opened conversations about revising openSUSE governance and more. So far, there is no concrete proposal to consider, no timeline, or even a process for the community and company to follow to make any decisions.

[$] Hierarchical storage management, fanotify, FUSE, and more

1 év 1 hónap óta
Amir Goldstein led a filesystem-track session at the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit on his project to build a hierarchical storage management (HSM) system using fanotify. The idea is to monitor file access in order to determine when to retrieve content from non-local storage (e.g. the cloud). The session was a follow-up to last year's introduction to the project, which covered some of the problems he had encountered; this year, he was updating attendees on its status and progress, along with some other problem areas that he wanted to discuss.

Redox to implement POSIX signals in user space

1 év 1 hónap óta

Redox has received a grant to work on implementing POSIX-compatible signals. The draft design calls for them to be implemented nearly completely in user space.

So far, the signals project has been going according to plan, and hopefully, POSIX support for signals will be mostly complete by the end of summer, with in-kernel improvements to process management. After that, work on the userspace process manager will begin, possibly including new kernel performance and/or functionality improvements to facilitate this.

[$] A hash table by any other name

1 év 1 hónap óta

On June 25, Matthew Wilcox posted a second version of a patch set introducing a new data structure called rosebush, which "is a resizing, scalable, cache-aware, RCU optimised hash table." The kernel already has generic hash tables, though, including rhashtable. Wilcox believes that the design of rhashtable is not the best choice for performance, and has written rosebush as an alternative for use in the directory-entry cache (dcache) — the filesystem cache used to speed up file-name lookup.

[$] Development statistics for the 6.10 kernel

1 év 1 hónap óta
The 6.10 kernel was released on July 14 after a nine-week development cycle. This time around, 13,312 non-merge changesets were pulled into the mainline repository — the lowest changeset count since 5.17 in early 2022. Longstanding tradition says that it is time for LWN to gather some statistics on where the new code for 6.10 came from and how it got to the mainline; read on for the details.
