Operator asked whether waiting is viable or whether a backports kernel is permanent. Answer: it will NOT arrive on its own, but it CAN be made to, and the ask is unusually strong. VERIFIED: - NOT in linux-6.12.y. Newest commit touching memattr.c on that branch is 2024-07-12. In mainline since v6.13 (2025-01-19) — ~19 months, ~97 point releases. - NO stable tag and NO Fixes: tag on either commit. Structural, not an oversight: the unvalidated arithmetic dates to the file's creation in 2016, so it is not a regression and there is no bad commit to point Fixes: at. BOTH automatic feeds — Fixes:-scanning and AUTOSEL — had nothing to grab. AUTOSEL never surfaced it for any branch. - NOBODY has requested it: nothing on [email protected], nothing in all 8,027 open+archived Debian bugs against src:linux. - 6.12 LTS EOL is December 2028 — outlives Debian 13's support window, so not time-barred. - Debian REBASES: trixie carries 6.12.94-1 in trixie-security ('New upstream stable update'), so an upstream pickup would reach us via a normal apt upgrade. THE DECISIVE CARD: the cherry-pick is BYTE-CLEAN. Debian trixie 6.12.94-1's memattr.c hashes to 164203429fa7a..., identical to the upstream patch's pre-image blob — the file has not diverged between v6.12 and the commit's parent. cherry-pick applies with zero conflicts and zero adjustment, which removes the usual reason such requests get declined. The commit also meets every stable-kernel-rules criterion: mainline, 17 insertions, 'hardware quirk', 'a real bug that bothers people'. PLAN: backports now as explicitly provisional; email [email protected] (rules Option 2) CC linux-efi and Ard Biesheuvel who authored AND committed it as EFI maintainer, leading with the clean-apply proof and the three-boot reproduction with byte-identical e820; Debian BTS as secondary under handbook §9.1.7; make the deviation permanent only if there is no movement in 4-6 weeks. Only 8fbe4c49c0cc is needed by hand — 5d0faa8e8369 loosens a heuristic that was rejecting LEGITIMATE tables and is not required for this symptom. Serves: R-ENV-01, R-ENV-03. Task: T-7.1.
infra/ — node provisioning and the toolchain
OpenTofu (Proxmox VE) + cloud-init + Ansible bring up the 3-node k3s/Cilium dev cluster.
Spec: ../home-network-k3s/docs/02-environments-and-provisioning.md.
| Path | What |
|---|---|
tofu/ |
The "Create" stage: 3 cloud-init'd VMs on the Proxmox box (bpg/proxmox provider) |
cloud-init/ |
First-boot baseline shipped as a Proxmox user-data snippet |
ansible/ |
The "Baseline"/"Configure" stages: k3s HA, Cilium, kube-vip, the VPN egress gateway |
devcontainer/ |
The pinned toolchain (tofu, ansible, sops, age, flux, kubectl, helm and the whole CI gate toolchain) |
cluster.sh |
RETIRED — drove the old libvirt VMs; does not work against Proxmox |
PHASE1-STATUS.md |
Current state of the cluster and how to reconnect to it |
PHASE1-SCOPE.md |
Historical Phase-1 scoping doc (libvirt era — superseded) |
Where the cluster actually lives
The dev cluster is not on this workstation. It runs on a Proxmox VE host; the nodes sit on the Proxmox LAN and are reached across a pfSense NAT:
| Nodes | k3s-dev-1/2/3 at 192.168.1.50/.51/.52 — 6 vCPU, 24 GiB, Debian 13, k3s v1.36.4 |
| kube-API | kube-vip VIP 192.168.1.49:6443, reached from the workstation via NAT 192.168.2.50:6443 |
| Node SSH | pfSense NAT 192.168.2.102:2250/2251/2252 → node :22 (Ansible only) |
| Ingress VIP | 192.168.1.53 (Cilium L2, shared Gateway); .53–.60 reserved for LB VIPs |
The earlier libvirt/KVM cluster on 10.73.0.0/24 is retired. Any doc or command referencing
virsh, qemu:///system, or 10.73.0.x for the cluster is historical.
