TCP Fast Open

[pysiak]

Would you consider adding TCP Fast Open support?
There's a small and simple example patch here:
https://github.com/dtaht/ceropackages-3.10/blob/cf6fd6a01fdfbddb468f2a3ea27b6450955b674a/net/polipo/patches/001-server_tfo.patch

Can you provide tcpdump traces that show that this patch actually does something?

I did this patch for cerowrt (bufferbloat.net) originally. At the time, the kernel was not fully baked to include TCP Fast Open support. I assume it is now. If adding TCP Fast Open is welcome in polipo, I can try provide the complete patch set along with any supporting logs, pcaps.

Please. Just a well-chosen pcap will be fine. Latency benchmarks welcome, of course, we all love benchmarks.

@ketkulka Any progress on this?

@simontretter see this commit - ab52932. I'm afraid it's time to close this and any other issues as WONTFIX.

Ketan, it seems we didn't make it with the FASTOPEN patch soon enough :-)
I was really going to produce tcpdumps for it as it''s trivial...
Anyway, thanks @jech for polipo. I've been chaining it with privoxy on my home router.
