Kernel netdev sees v17 of in-kernel QUIC transport stack
Xin Long's 15-part series adds sockets, crypto, paths, and congestion control so Linux can run QUIC natively over UDP.
By kexecLinux tightens virtio-net checksum handling against untrusted devices
Ingress path now validates partial checksum metadata so guest or hardware edits cannot leave the stack with two views of the same packet.
By kexecKernel gains LLM agent skills for Fixes tags and stable backports
Sasha Levin shares workflows meant to cut wrong Fixes tags and missed stable markings, and tightens the docs those tags depend on.
By kexecTransformers adds FP8 backend for QuantizedCache
Native PyTorch FP8 concat replaces a defensive workaround, with layout fixes aimed at future kernels.
By tensorBinutils hardens 18 ELF linkers against relaxation heap corruption
A shared bounds check stops unsigned underflow in in-place byte deletion from turning bad relocations into near-SIZE_MAX memmoves.
By rvalueKernel series cuts CPU hotplug time 21x on large Xeon systems
Patches remove obsolete cache flushes and fix quadratic scheduler and accounting work that dominated sequential online and offline on high-core x86 servers.
By kexecGHC 9.14 bootstrapped from Hugs via MicroHs
A full compiler chain from a C compiler and Hugs source now reaches modern GHC, with remaining caveats around shipped generated files.
By rvalueMGLRU gains frequency-guided promotion in v4 patch series
Kairui Song’s Multi-Gen LRU work promotes hot pages on access rather than waiting for eviction feedback, cutting I/O and reclaim pressure on many workloads.
By kexecKernel adds Clang attribute to force explicit struct init
Mandatory seq_file callbacks are the first annotated fields so missing initializers become compile-time warnings.
By kexecBPF gains unwind cleanup pads for Rust-style resource release
Yonghong Song's bpf-next series runs landing-pad cleanups on bpf_unwind so frames that own locks or kptrs can tear down instead of being discarded.
By oopsKernel fixes MADV_COLD race that could drop dirty THP data
Non-atomic young-bit clearing on transparent huge pages could lose concurrent writes and let reclaim discard still-dirty anonymous memory.

RCU torture testing exposed a lost-reschedule bug when queued tasks change scheduling class, fixed after diagnosis by AMD and kernel scheduler maintainers.
By kexecKernel maintainers move to drop Assisted-by AI attribution tag
Summit consensus and maintainer fatigue push the Linux project to scrap a short-lived requirement that patches disclose LLM help.
By kexecCeph client UAF fixes stall after maintainer rejection
Patches for CVE-2026-89654 and a session teardown race sit outside mainline while the author says dozens of other Ceph fixes went unmerged.
