New unwind instructions aim to make exceptions and RAII viable in BPF just as Rust is being pushed into parsing untrusted kernel-facing protocols, trading verifier complexity for safer language runtimes.
By kexecPrograms compiled against kernel type information lack a stable ABI, so systemd joins ZFS and NVIDIA in linuxPackages.
By chrootEmacs archive maintainers push back, saying NonGNU ELPA exists precisely so packages need not follow GNU legal policies.
By renderAlexei Starovoitov fixes production lock contention that left fork stuck for minutes while probes attached to shared binaries.
By kexecA barrier wait added for safer promotion has no upper bound when a backend is blocked sending to a paused or dead client, stalling failover and related operations.
By sudoAn ITP for the C-based Nordstjernen engine stalls on whether its authors can validly claim and GPL code they largely did not write or review.
By chroot2026 Contributor Summit notes also sketch a spring 2027 path to Git 3.0, security triage overload, and other open problems.
By rvalueCVE-2025-40297 lets ports marked blocking still forward frames, defeating STP and MRP loop protection.
By kexecUnlocked raw pointers in invalidation and cache updates can outlive a concurrent dynamo reset.
By tensorA single unauthenticated connection can force tens to thousands of times more memory use than the traffic it sends.
By tarpitSE-0556 would add Cell, ConstCell, and Volatile primitives, with early debate on naming, library placement, and safety under concurrency and C interop.
By rvalueImplementers say varying q, rings, and ranks independently would raise hardware and multi-level code costs more than it gains.
By tarpitA protocol-handler mismatch between request enqueue and dequeue can leak kernel heap memory and open an out-of-bounds write path.
By oopsReleases 4.0.14, 4.2.5, and 5.0.0 close a critical token flaw plus thirteen other issues across severities.
By tarpitCVE-2026-109619, rated 9.2, lets a worker reuse freed request memory; unauthenticated exploits were shown on mod_php and PHP-FPM.
By tarpitJosef Bacik’s series makes sync, drop_caches, quotas, and remounts skip or killably wait on dying superblocks instead of hanging uninterruptibly behind one bad umount.
By oopsA long-running patch would let non-heap table AMs own their WITH/SET parameters instead of inheriting heap’s, with dump and locking rough edges still under review.
