📰 Little Snitch, the macOS network tool, is now available on Linux A Linux version of Little Snitch, the iconic network monitoring and firewall tool for macOS, has been released. Little Snitch for Linux is written in Rust and uses eBPF for kernel-level traffic interception (which lets sandboxed code run inside the Linux kernel without modifying it). The tool lists processes on your machine making network connections, with options to block them. 🔗 Source: https://www.omgubuntu.co.uk/2026/04/little-snitch-linux #linux#kernel

📰 Linux's Second-In-Command Turns To New Fuzzing Tools For Uncovering Kernel Bugs Greg Kroah-Hartman, the main Linux stable kernel maintainer and typically viewed as the second-in-command to the Linux kernel development, has turned to new "gregkh_clanker_t1000" fuzzing tooling to help uncover new kernel bugs... 🔗 Source: https://www.phoronix.com/news/Greg-KH-Clanker-Linux-Bugs #linux#kernel

📰 RISC-V XIP Linux Feature Being Removed After It Keeps Breaking For Months At A Time Introduced in Linux 5.13 back in 2021 was eXecute In Place "XIP" support for RISC-V that allows for the kernel image to be executed from ROM. The intent is on allowing the kernel to run from non-volatile storage like NOR flash that is directly addressable by the CPU and to reduce RAM usage. But after RISC-V XIP support is broken for months at a time, the feature is now set to be retired from the mainline kernel... 🔗 Source: https://www.phoronix.com/news/RISC-V-XIP-Being-Removed #linux#kernel

📰 Patch to end i486 support hits Linux kernel merge queue After a year of patchwork, maintainers look ready to start retiring 486-class CPUs It's taken nearly a full version number to get the pieces in order, but the long-awaited end of 486 chip support in the Linux kernel appears to be nigh with Linux 7.1's release later this year. … 🔗 Source: https://go.theregister.com/feed/www.theregister.com/2026/04/06/patch_to_end_i486_support/ #linux#kernel

📰 Meta Has A New Linux Optimization To Avoid Throttling TCP Throughput Unnecessarily Meta's great Linux engineering team have been working through some fresh performance optimizations recently from optimizing /proc/interrupts outputs to renewing their investment in jemalloc. A new Linux kernel patch this week provides another optimization to avoid a possible situation of throttling the TCP throughput unnecessarily on Linux systems... 🔗 Source: https://www.phoronix.com/news/Linux-VM-Pressure-TCP-Through #linux#kernel

📰 The Linux Kernel's Minimum Rust Version Supported Prepares For Rust 1.85 Baseline The Rust-For-Linux crew is preparing to raise the minimum supported Rust version for building the Linux kernel and and similarly also bumping the minimum supported version of bindgen, the tool for generating Rust FFI bindings for C code in the kernel... 🔗 Source: https://www.phoronix.com/news/Linux-Preps-For-Rust-1.85-Base #linux#kernel

📰 New Rust-Based BUS1 In-Kernel IPC In Development For The Linux Kernel After KDBUS failed to make it into the mainline Linux kernel more than one decade ago as an in-kernel version of D-Bus, BUS1 was proposed as a clean sheet design for in-kernel, capability-based inter-process communication (IPC). BUS1 didn't gain enough traction to make it to the mainline kernel and then many of the same developers devised Dbus-Broker as a more performant D-Bus user-space implementation. 🔗 Source: https://www.phoronix.com/news/BUS1-Linux-2026 #linux#kernel

📰 Linux Ham Radio KISS Serial Driver Being Modernized In 2026 Here's something that wasn't on my bingo card for this year of the "MKISS" driver for ham radio being modernized in 2026 as opposed to just being dropped.
