Systemd v261 has been released with a long list of changes, including a new cloud "Instance Metadata Service" (IMDS) subsystem, "boot secret" functionality for use on systems that lack a physical TPM, as well as support for the kernel's Live Update Orchestration (LUO) / Kexec Handover (KHO) systems when they are present and enabled. See the release notes for the full list of changes.
BPF programs can be used to extend many aspects the Linux kernel, but BPF programs must run to completion in the same context that they began. Kumar Kartikeya Dwivedi is working on changing that by allowing BPF programs to be expressed as coroutines. He spoke about his work at the 2026 Linux Storage, Filesystem, Memory-Management and BPF Summit. While still experimental, the change promises to make long-running BPF tasks significantly easier to write.
The Arch User Repository (AUR) has been subjected to a sustained attack recently. The attacker, or attackers, have spun up a series of new accounts then used them to adopt orphaned packages and push malicious updates that would install malware on users' systems. It is unclear how many users were compromised in the attack, but the maintainers were playing Whac-A-Mole for several days to respond to each newly compromised package. The project has turned off the AUR's new-user registration, for now, but it is unclear what its long-term response will be or if the AUR can be secured without major changes to its existing collaboration model.
