During March 2026, delivered a cohesive Kernel 6.18 integration for Bottlerocket across bottlerocket-kernel-kit and bottlerocket-core-kit, enabling external module support, improved kernel command-line handling, and device driver readiness. Key changes include EFA module packaging, VMware bootconfig integration, and Neuron driver support to broaden hardware compatibility; updated Neuron packages for Inf1 compatibility to ensure performance parity with the new kernel. Additionally, expanded SELinux policy coverage for kernel 6.18 to strengthen security and governance: added io_uring allowed permission, watch_mountns, firmware_load, and netlink nlmsg permissions, enabling secure operation of modern kernel features without sacrificing compatibility. A notable reliability improvement was implemented in the build system by fixing a parallel build race in libperf header installation, reducing sporadic compile failures under concurrent builds. Release readiness was advanced with preps for Bottlerocket v5.3.0 (kernel 6.18) and Bottlerocket v13.4.0, including version bumps and changelog updates to document security and feature enhancements. Technologies demonstrated include kernel patching and packaging, driver integration (Neuron/Inf1), kernel module packaging (EFA), SELinux policy engineering, build-system reliability improvements, and release engineering.
