💖 NAME 💖

BPFTUNE-NETNS — from the System Manager's Manual, it's the bpftune plugin that does network namespace awareness 🦋

✨ DESCRIPTION ✨

okay so bestie, let me put you on 🫶

bpftune needs to be namespace-aware — like, this is not a want, it's a need, it's giving main character requirements only 💅

When it receives events, those events are tied to a specific netns cookie. And the way that we see an event in that netns, we wanna be able to auto-tune within it — and not in the global network namespace. periodt. no notes. 👑

On startup, the netns tuner iterates over the various sources of netns info to collate a list of network namespaces, and then it supplements this by watching for addition of network namespaces via BPF. 🔥 Using all of that info, we can then maintain tuner state on a per-namespace basis. and honestly? iconic. fr fr. 🌸

⚠️ heads up babe — Per-namespace support requires netns cookie support. running bpftune -S shows if this is present. so go run it, iykyk 💀✨
