Toke and jesper and stephen hemminger are there, anyone else? There's also some "bloat" business of course to do. Obviously talk about the state of the bloat, the l4s & sce work, etc. but: I have a bunch of other "plumbing" stuff that's been bugging me lately, and perhaps there are those here that might have more? I should try to find people to talk to about, or knew who I should? 1) Recently (in a limited set of coffee shop tests), I saw 30+% of ipv4 tcp syns being retried. That's scary, I don't know if anyone's tracking that in any way? It seems possible to track it with in-browser statistics, possibly. I'm afraid a syn-limiter is in place with copy-pasted parameters set in the 90s - openwrt's default, last I looked, was 25/sec. 2) I'd really like somehow for atomic route updates to "just work". I think it's working now for ipv4, at least, as I saw a commit go in for it for bird, recently. That plus sorta-kinda-wanting to see pmtu work better for udp is on my mind. 3) Our biggest problem bufferbloat-wise is inbound shaping and I don't know how to make it better aside from resuming work on a smarter policer. 4)? I'm pretty broke as usual (LF is paying for the plane and airbnb (thx LF!), but not food or my time), if anyone could throw a few bucks into my gofundme or patreon, it would be appreciated. -- Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740
