Good morning, it's Friday, September 25th, 2026, and this is Linux Kernel Daily.
Late release candidate stability is the story, with a very large networking fixes pull alongside focused corrections to the extensible scheduler and to Landlock tracing.
First, networking memory safety and hangs. The net pull for 7.3 release candidate 5 spans almost 190 commits, and the pattern is small paths that can panic, corrupt, or strand memory. For VLAN devices, the header builder now ensures sufficient headroom when packets arrive with short reservations or after headroom…
Second, the schedulable-extensions framework gets five concurrency fixes. A task requeued during dispatch could lose future dispatches, a remote wakeup could strand a local requeue request into freed memory if the scheduler unloaded, and the dequeue callback ran with a queue lock held, deadlocking schedulers that…
Third, Landlock fixes its new tracepoint contract so filesystem, network, signal and process-tracing denials report the intended policy context, backed by new tests.
Expect further validation around custom schedulers, packet forwarding edge cases, and security audit consumers. That's today's briefing.
