20 min

A stripped down episode, this is a heart-to-heart chat between me and you about the Linux community, burnout, detours, and things you never expect to face.

Adventures in Freebernetes, tracing kernel functions, The better way of building FreeBSD networks, New beginnings: CDBUG virtual meetings, LibreSSL update in DragonFly, Signal-cli with scli on FreeBSD, and more. NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines Adventures in Freebernetes: bhyve My Guest (https://productionwithscissors.run/2020/10/29/adventures-in-freebernetes-bhyve-my-guest/) Part 2 of experiments in FreeBSD and Kubernetes: Creating your first guest Tracing Kernel Functions: FBT stack() and arg (https://zinascii.com/2020/fbt-args-and-stack.html?s=03) In my previous post I described how FBT intercepts function calls and vectors them into the DTrace framework. That laid the foundation for what I want to discuss in this post: the implementation of the stack() action and built-in arg variables. These features rely on the precise layout of the stack, the details of which I touched on previously. In this post I hope to illuminate those details a bit more with the help of some visuals, and then guide you through the implementation of these two DTrace features as they relate to the FBT provider. News Roundup Dummynet: The Better Way of Building FreeBSD Networks (https://klarasystems.com/articles/dummynet-the-better-way-of-building-freebsd-networks/) Dummynet is the FreeBSD traffic shaper, packet scheduler, and network emulator. Dummynet allows you to emulate a whole set of network environments in a straight-forward way. It has the ability to model delay, packet loss, and can act as a traffic shaper and policer. Dummynet is roughly equivalent to netem in Linux, but we have found that dummynet is easier to integrate and provides much more consistent results. New beginnings: CDBUG virtual meetings (http://lists.nycbug.org/pipermail/cdbug-talk/2020-October/000901.html) I had overwhelmingly positive responses from the broader *BSD community about restarting CDBUG meetings as virtual, at least for now. Hopefully this works well and even when we're back to in-person meetings we can still find a way to bring in virtual attendees. LibreSSL update in DragonFly (https://www.dragonflydigest.com/2020/11/10/25143.html) DragonFly has a new version of libressl, noting cause it has a newer TLS1.3 implementation – something that may be necessary for you. Signal-cli with scli on FreeBSD (https://antranigv.am/weblog_en/posts/freebsd-signal-cli-scli/) So couple of days ago I migrated from macOS on Macbook Pro to FreeBSD on ThinkPad T480s.
