The latest Linux 5.14 kernel is just around the corner and with contributions from 1,650 developers there are some interesting updates to security and performance. In particular a new way to deal with Spectre and Meltdown which gained widespread notoriety in 2018 and creating memory ranges inaccessible to anyone.
It will be interesting to see folks testing this release in their labs while they re-enable hyper-threading. Would love to see some community charts, and graphs that show the before and after.
In addition to the core scheduling update, another new security update that caught my interest was memfd_secret (). I’ll be watching this one closely and wanting to hear from the community on their experience.
Once released you can download the 5.14 kernel and apply it to your test servers manually. Most Linux vendors will include the updated kernel in their next release. I will likely wait for it to be included in my distro of choice.
What has you excited about the Linux 5.14 kernel? Is this something you will download and test right away or will you wait for your favorite distro to include it. Let me know on Twitter and thanks for reading.
