📝 WalkthroughWalkthroughThe OKE GB200 and L40S training recipes now configure Network Operator networking for InfiniBand or RoCE RDMA devices. GB200 GPU Operator settings enable the required kernel-module configuration. GB200 OKE validation now runs NCCL NET and NVLS checks. A GB200 OKE NET runtime and benchmark mapping were added. Image inventories, digest exemptions, and generated recipe digests were updated. Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds digest exemptions for new network manifests, but the validation currently applies them globally rather than only to NicClusterPolicy resources; a reused tag elsewhere could bypass the digest-pinning check. This is a bounded follow-up, so the PR is mergeable with owner awareness. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 1❌ Failed checks (1 warning)

Upstream the OKE network fabric, closing gb200-oke-training's 'NET/RDMA intentionally left out until OCI-specific pod RDMA exposure is verified on the testbed' carve-out — the exposure below is validated on a production BM.GPU.GB200.4 NVL72 rack and a BM.GPU.L40S.4 RoCE cluster. - network-operator on both OKE training chains, NicClusterPolicy supplied by manifest (chart deployCR off). L40S (RoCE): SR-IOV VF device plugin advertising nvidia.com/mlnxnics (ConnectX VF device IDs 101a/101e) plus nv-ipam and multus. GB200 (IB): rdmaSharedDevicePlugin over the NVL72 east-west rdma0-3 netdevs, same nvidia.com/mlnxnics resource name; no SR-IOV/nv-ipam. Neither deploys ofedDriver: OCI nodes carry host MOFED in every image. Present in every gpuStack value (fabric is orthogonal to driver/plugin ownership); incompatible with Oracle's opt-in NvidiaNetworkOperator add-on. - GB200 kernel-module-params wiring (NVreg_GrdmaPciTopoCheckOverride=1): dma-buf attach over the IB fabric — GPUDirect RDMA without nvidia-peermem, whose chroot modprobe fails against the -64k Grace kernel. - nccl-all-reduce-bw-net (>= 40, matching gb200-eks-training) added to the gb200-oke training chain; supportedNCCLCombinations[variantNET] gains oke/gb200 with the ported testdata/gb200/oke/runtime-net.yaml TrainingRuntime (IB via the shared HCAs; NVLS/MNNVL forced off). - NicClusterPolicy image digest exemptions (repository/image/version triplet CRD schema, same as the AKS entries).

Scope the exemptions to NicClusterPolicy resources.
TestComponentManifestImagesAreDigestPinned checks the global imageDigestExemptions map for every image in every component manifest. The four current references occur only in nic-cluster-policy-oke-l40s.yaml, but another resource can reuse one of these tags and bypass the digest check. Scope each exemption by manifest or resource context.

Summary
Upstreams the OKE RDMA fabric: network-operator with manifest-supplied NicClusterPolicies on both OKE training chains (L40S SR-IOV/RoCE, GB200 IB), the GB200 kernel-module-params wiring, and the
nccl-all-reduce-bw-netperformance gate with its embedded TrainingRuntime — closing thegb200-oke-training"NET/RDMA intentionally left out until OCI-specific pod RDMA exposure is verified" carve-out.Motivation / Context
The exposure the carve-out was waiting for exists and is production-validated: a BM.GPU.GB200.4 NVL72 rack (IB east-west over rdma0-3,
rdmaSharedDevicePlugin, both NCCL variants passing) and a BM.GPU.L40S.4 RoCE cluster (SR-IOV VFs via device IDs 101a/101e, nv-ipam + multus). This PR ports that configuration from the downstream data repo, de-specialized: hardcoded scheduling taxonomy replaced by the bundler's system-node scheduling injection, downstream-only tolerations and resource aliases dropped.Stacked on the OKE gpuStack profile PR — the fabric is deliberately present in every profile value (orthogonal to driver/plugin ownership); retargets when the base merges.
