Source code sandboxing

1 hónap óta

Kristaps Dzonsons (known for mandoc(1), rpki-client(8), and much more) has written an article, Source code sandboxing, on sandboxing from the perspective of developers. It compares the facilities available under several operating systems, and requests relevant contributions.

As Undeadly readers might expect, OpenBSD's pledge(2) and unveil(2) receive favourable appraisal.

Kristaps' article refers to Sandboxing Adoption in Open Source Ecosystems, an academic article published on the subject.

[In 2016, Undeadly published Kristaps Dzonsons on pledge(2).]

Ubuntu 25.10 to drop support for GNOME on Xorg

1 hónap óta

Jean Baptiste Lallement, a member of Canonical's desktop team, has announced that Ubuntu will drop support for GNOME on X11 in the 25.10 ("Questing Quokka") release set for October. GNOME plans to remove X11 support in GNOME 49, which is scheduled for September, so Ubuntu is looking to be proactive:

Ubuntu 25.10 is the last interim release before our next LTS (Ubuntu 26.04). By moving now, we give developers and users a full cycle to adapt before the next LTS, align with GNOME 49 and reduce fragmentation while simplifying our support matrix heading into the LTS.

Fedora decided in early May to drop X11 support for GNOME in Fedora 43, which is also due in October.

[$] Improving iov_iter

1 hónap óta
The iov_iter interface is used to describe and iterate through buffers in the kernel. David Howells led a combined storage and filesystem session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF) to discuss ways to improve iov_iter. His topic proposal listed a few different ideas including replacing some iov_iter types and possibly allowing mixed types in chains of iov_iter entries; he would like to make the interface itself and the uses of iov_iter in the kernel better.

[$] An end to uniprocessor configurations

1 hónap óta
The Linux kernel famously scales from the smallest of systems to massive servers with thousands of CPUs. It was not always that way, though; the initial version of the kernel could only manage a single processor. That limitation was lifted, obviously, but single-processor machines have always been treated specially in the scheduler. That longstanding situation may soon come to an end, though, if this patch series from Ingo Molnar makes it upstream.

20 Years of the Open Invention Network

1 hónap óta
The Open Invention Network (OIN) is celebrating its 20th anniversary.

The central feature of the OIN community is a patent cross-license that covers core Open Source functionality and expands in parallel with the growth of Open Source technology. As growth in Open Source has accelerated, OIN has proactively expanded the scope of the OIN license's benefit by including more than 4,500 software components and platforms in its Linux System definition, which comprises the list of Open Source code and associated functionality in OIN's patent cross-license.

LWN's first look at OIN was this article by Pamela Jones in late 2005.

Three stable kernel updates

1 hónap óta
The 6.15.2, 6.14.11, and 6.12.33 stable kernel updates have been released; each contains a relatively small set of important fixes.

Note that this is the end of the line for the 6.14.x updates; Greg Kroah-Hartman explains the timing of this move:

If you notice, this has happened a bit more "early" than previous end-of-life announcements. Normally, after -rc1 is out there is a TON of stable patches happening due to the changes that come into the merge-window that were marked for stable backports but didn't get into Linus's release before -final. As some people have objected to this large influx being added to a stable kernel that is just about to go end-of-life, let's try marking this end-of-life a bit earlier to see how it goes.
