(Commit: 5cb1332348359ce0f60a9619bdc1b21c5123d010) - TDX QGS port configurability: remove default QGS port and allow setting port to 0 to respect user-provided values. (Commit: 6f45a7f9379bbd567f99f3d6cfb69e418c481936) Major bugs fixed: - No major bugs identified in this period. Focus remained on feature delivery and compatibility enhancements across the CoCo-enabled stack. Overall impact and accomplishments: - Strengthened security posture with an up-to-date kernel-confidential baseline and verified CoCo 0.16.0 compatibility across critical components. - Expanded deployment scenarios by enabling NVIDIA-attester for coco-guest-components and introducing explicit port configurability for TDX QGS. - Improved reproducibility and traceability through targeted commits across kernel, components, and runtime configurations. Technologies/skills demonstrated: - Linux kernel configuration and confidential computing (kernel-confidential, CoCo) on Linux v6.16.7 - CoCo v0.16.0 ecosystem alignment (agent-ctl, coco-guest-components, trustee; ITA v2 API paths) - NVIDIA-attester integration for x86_64 root filesystems - Runtime configurability (TDX QGS port=0)

August 2025 was a focused iteration across two repos, delivering foundational platform improvements, security-related enhancements, and build/test reliability. In intel/intel-device-plugins-for-kubernetes, we upgraded the Go tooling/runtime to Go 1.25 (with Trixie) and added compatibility tests for Go 1.34.x, introduced SGX-specific resources to enable quoting daemons and platform registration without elevated privileges, refined documentation link readability for OpenSSF Scorecard, performed sweeping internal maintenance to reduce copies and governance overhead, and upgraded Kubernetes dependencies to 1.34.0. In kata-containers/kata-containers, we stabilized Confidential VM memory handling by disabling memory hotplug for ConfidentialGuests, and updated the kernel build environment to include libdw-dev and python3 for building newer kernels (6.16+).

July 2025 performance summary: Delivered notable platform enhancements and tooling upgrades across two repos, with a focus on hardware support, tooling modernization, and security-conscious kernel updates. Key activities included enabling QAT Gen6 support in the QAT plugin, upgrading CRD tooling and controller-gen, updating CI to test with Go 1.33.x, and upgrading the confidential container kernel to Linux v6.16.1 with TDX support. No major bug fixes were recorded this month.

June 2025 highlights reliability improvements and OS/version coverage for sandboxed containers and Kata containers across two repositories. Key features delivered include (1) Intel Device Plugin Operator upgrade to v0.32.1 for the baremetal-coco component with installation config updates (starting CSV in install_operator.yaml) and image SHA update in sgx_device_plugin.yaml to ensure compatibility with OpenShift 4.18, plus a startup wait condition for the webhook to ensure the controller manager has an endpoint IP before applying SGX deployment, improving installation reliability. (2) Kata deployment enhancement adding Ubuntu 25.04 support for TDX deployments by updating the kata-deploy script to accept 25.04 and pointing to TDX repo version 3.3 for the latest enablement. These changes reduce installation failures and broaden OS compatibility for SGX-enabled workloads and TDX-enabled Kata deployments.
