Address-space isolation may well be, as Brendan Jackman said at the beginning of his memory-management-track session at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, 'some security bullshit'. But it also holds the potential to protect the kernel from ...
The kernel must often step through the page tables of one or more processes to carry out various operations. This 'page-table walking' tends to be performed by ad-hoc (duplicated) code all over the kernel. Oscar Salvador used a memory-management-track session at the 2025...

Saying that calibre is ebook-management software undersells the application by a fair margin. Calibre is an open-source Swiss Army knife for ebooks that can be used for everything from creating ebooks, converting ebooks from obscure formats to modern formats like EPUB, to...
José Marchesi and David Faust kicked off the BPF track at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit with an extra-long session on what they have been doing to support compiling to BPF in GCC. Overall, the project is slowly working toward full...
Ryan Sipes has announced efforts to expand Thunderbird's offerings with web services to 'enhance the experience of using Thunderbird'. The Why for offering these services is simple. Thunderbird loses users each day to rich ecosystems that are both clients and services, such ...
Outgoing Fedora Project Leader (FPL) Matthew Miller has announced his successor, Jef Spaleta. Some of you may remember Jef's passionate voice in the early Fedora community. He got involved all the way back in the days of fedora.us, before Red Hat got involved. Jef served on ...
Version 2.0 of PorteuX, a distribution based on Slackware Linux, has been released. This release adds the ability to test experimental Wayland sessions for the Cinnamon, LXQt, and Xfce desktops. PorteuX 2.0 updates the Linux kernel to 6.14 and includes many package updates...
The CPU's translation lookaside buffer (TLB) caches the results of virtual-address translations, significantly speeding memory accesses. TLB misses are expensive, so a lot of thought goes into using the TLB as efficiently as possible. Reducing pressure on the TLB was the...
For those of you who still have dedicated audio players: version 4.0 of Rockbox, a replacement firmware for many players, has been released. This release brings support for a number of new devices, updated codecs, a number of user-interface improvements, some new games, and...

The kernel's slab allocator is charged with providing small objects on demand; its performance and reliability are crucial for the functioning of the system as a whole. At the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, two adjacent sessions in the...
From the LibreQoS site comes the sad news that Dave Täht has passed away. Among many other things, he bears a lot of credit for our networks functioning as well as they do. 'We're incredibly grateful to have Dave as our friend, mentor, and as someone who continuously...
As he has in some previous editions of the Linux Storage, Filesystem, Memory-Management, and BPF Summit (LSFMM+BPF), Fred Knight gave an update on the status of various storage standards this year. In it, he looked at changes to the NVM Express (NVMe) standards in some...
The kernel's kexec mechanism allows one kernel to directly boot a new one; it can be thought of as a sort of kernel equivalent to the execve() system call. Kexec has a number of uses, including booting a special kernel to perform dumps after a crash. Normally, one does not...

The virtual memory area (VMA), represented by struct vm_area_struct, is one of the core abstractions of the kernel's memory-management subsystem; a VMA represents a portion of a process's address space with the same characteristics. A memory-mapped file will be represented...
