When troubleshooting with bpftrace, you don't want to have to troubleshoot bpftrace itself! bpftrace needs to be really reliable. At #LinuxPlumbers, Daniel Xu (Meta) explained why and how he built a Nix-based CI to address this challenge.

Next at #LinuxPlumbers, to improve the #eBPF verifier, @kkdwivedi (EPFL) proposes KFlex, a better tradeoff between runtime sandboxing (ex. SFI) and static analysis (the eBPF verifiers). Out of all the approaches presented to improve/replace the verifier, this is IMO the most likely to make it upstream!

At #LinuxPlumbers, Arpad Kis explains what it took to create a new userspace #eBPF VM and have it run Doom.

In the #eBPF verifier, tnums are a bitwise way to track possible values for variables, by tracking known bits.
@shunghsiyu (SUSE) explains how they work at #LinuxPlumbers. All attendees should be able to review that code at the end of the talk!
