Report for 2018-08-01 to 2018-08-31

This report covers the development in the linuxkit/linuxkit linuxkit/lcow linuxkit/kubernetes linuxkit/virtsock linuxkit/rtf linuxkit/homebrew-linuxkit repositories. There were 122 contributions (PRs/Issues/Comments) from 24 individual contributors. 19 new PRs were opened and 17 PRs were merged. 8 new issues were opened and 4 issues were closed.

August was relatively slow on the development side due to summer holidays. Nevertheless, we merged support for the BCC eBPF tools and tweaked the kernel configuration to improve container startup times for 4.14.x and newer kernels. We also added support for the recently released 4.18 kernels. The kernel updates and Intel ucode updates include important mitigations to yet more speculation issues (L1TF in this case). containerd was updated to v1.1.3, the -rt kernels to 4.14.63-rt40, WireGuard to 0.0.20180809, and the Docker DinD sample to 18.06.0-ce. The VirtualBox now supports multiple disks and network adapters.
