Hey everyone, I promised to resend this one more time once we have confirmed the dates for Virtual Linux Plumbers 2020: Linux Plumbers 2020 will take place from Monday, 24 August to Friday, 28 August. As usual it also encompasses Kernel Summit. We're happy to announce that the Container and Checkpoint/Restore microconference (MC) has been accepted as part of Linux Plumber's again! The Containers and Checkpoint/Restore MC at Linux Plumbers is the opportunity for kernel developers, runtime maintainers, and generally everyone working on containers and related technologies to talk about what they are up to and agree on the next major changes to kernel and userspace. As we have already done the last years, the micro-conference also covers topic of the Checkpoint-Restore micro-conference. Please note that LPC 2020 was originally set to be held in Halifax, Nova Scotia, Canada but has been moved to a virtual event in light of recent events. Please see our organizing comittee's blog on the Plumber's website [1] for more information. We expect to time limit presentations/demos to 15 minutes including questions. More open ended discussion topics will get up to 30 minutes allocated. In the spirit of a Plumber's microconference we especially appreciate topics pitching new ideas and features people have been thinking about. This is also the time to talk about your favorite kernel- or userspace problems. If you have a proposal how to solve them or if you just want to gather input and ideas from other developers this is the right place. Here are some ideas for topics: System call filtering and interception Hardware enforced container isolation New seccomp features New cgroup features Handling cgroup v1 on cgroup v2 only hosts and vica versa Performance improvement for containers (following Spectre/Meltdown mitigation) Time namespacing CGroupV2 developments LSM, IMA, EVM, keyrings inside containers UID shifting filesystem (shiftfs) New mount API New pidfd API New clone3 syscall CRIU integration with container engines and orchestration frameworks (In)stability of less commonly used kernel ABIs Checkpoint/Restore performance improvements Improving the state of userfaultfd and its adoption in container runtimes Speeding up container live migration Extending and virtualizing procfs Restricting path resolution Android containers and containers on Android Container Auditing and Monitoring Cgroups and Containers with Real-Time Scheduling Some of those are ideas in search of an acceptable solution, some are problems likely to affect all container runtimes some are coverage of very recent kernel work and how that can be used by userspace, and some are proposed kernel patches that need in-person discussion. This list is not meant to be exhaustive. If you have other ideas or work to discuss, please apply! Keep in mind both kernel- and userspace topics are acceptable! Please make your proposals on the Linux Plumber's website selecting the Containers and Checkpoint/Restore MC as the Track you're submitting at: https://linuxplumbersconf.org/event/7/abstracts/ We’ll accept proposals for this micro-conference until the 20 of July 2020. This year’s edition of the micro-conference is organized and run by: Christian Brauner (Canonical Ltd.) Stéphane Graber (Canonical Ltd.)
