nix flake update nixpkgs uds-rdma-proxy on both benchmark hosts: nixpkgs e5bdc4a -> 56c02bc (linuxPackages_latest -> 7.2) uds-rdma-proxy 4349465 -> a25a13c (main; in-order RX copy-elision) Both hosts deployed + rebooted onto 7.2.0 (urp loaded). Verified with .#urp-reorder-matrix hp1 hp3 10.10.2.1 -> GREEN, 9/9 cells, drops=0. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Move the two RoCEv2 benchmark hosts (
hp1acceptor,hp3initiator) onto Linux 7.2 — the kernels had moved on from 7.1.8.nix flake update nixpkgs uds-rdma-proxyon each host's flake:e5bdc4a56c02bc(linuxPackages_latest→ 7.2)4349465a25a13c(main; in-order RX copy-elision)Both hosts already track
nixpkgslinuxPackages_latest, so this is purely a pin bump — no config change.Deployed + verified
Built the closures (kernel 7.2.0), deployed via the no-push recipe (nix copy → ESP guard →
nix-env --set→switch-to-configuration boot→ reboot). Both hosts now run 7.2.0 withurploaded.nix run .#urp-reorder-matrix hp1 hp3 10.10.2.1→URP_REORDER_RESULT=GREEN— 9/9 cells PASS, everyreorder_drops=0(buffer_size 68 / 4096 / 65516 ×num_qps{1,4,8}, multi-QP reorder path exercised, byte-exactverify=full).dmesgclean on both boxes (only benign firmware/ACPI warnings).Pairs with
