HAWK exits and McEliece parameters buckle under fresh attacks
An AI-assisted lattice reduction forces HAWK out of the NIST signature round while quasipolynomial results leave Classic McEliece's proposed sizes without defenders.

From blanket bans to AGENTS.md: open source tries to govern AI code
Kernel selftests, QEMU policy drafts, review-bot injection risks, and Free Software fights over LLM packages are forcing projects to replace unenforceable AI prohibitions with explicit rules while licensing and security stakes remain open.
By kexecWhen dual maintenance ends: Rust Binder deletion and the nova-core binding fight
A proposal to delete the C Binder driver and NVIDIA’s expanding Rust vGPU stack force the kernel community past experiments into the harder question of retiring C subsystems.

A proposed change would process output channels concurrently and cut redundant writes on common Fold shapes.
By tensorKernel series fixes coredump UAF, truncated dumps, and hangs
Christian Brauner’s multi-patch stable-bound work closes races among coredumps, signals, freezers, and io_uring workers.
By kexecIOMMU live-update patches aim to keep VM DMA mappings across kexec
Google's v5 series preserves Intel VT-d and iommufd domain state so assigned devices can survive a kernel live update without dropping translations.
By oopsRFC keeps KVM guests running across host kexec live updates
Pasha Tatashin’s early OrphanVM proof of concept preserves physical CPUs so vCPUs keep executing while the host kernel is replaced.
By oopsLinux NVMe adds TP8028 cross-controller path recovery
Host and target support for Rapid Path Failure Recovery lets multipath NVMe fence a dead path before failover, avoiding double completion and data corruption.

Yonghong Song's bpf-next series lets bpf_throw() run compiler-emitted landing pads so frames can release locks and owned objects on the way out.
