Attendees: rscheff@ and tuexen@ tried you join, but could not. The call was somehow removed from the calendars. Used an alternate meeting session.
- Gleb is suggesting to remove the compressed TCP TIMEWAIT state. The memory savings are limited, memory is not that critical anymore and it would simplify the code and allow further optimizations of the code. glebius@ will reach out to people if there are some objections. It was also discussed which information would be need to reduce the time a TCP connections stays in TIMEWAIT state. One thing he will implement is a counter how many compressed states where used at all. Discussion has been started on net@.
- ECN implementation has been improved. The code is now contained in one file tcp_ecn.c.
- D21011 is implementing Accurate ECN and has been updated and will be reviewed by rrs@ and tuexen@.
- D23230 is implementing ECN++.
- D30043 is a small whitespace cleanup.
- D28822 improves PRR, needs some cleanup.
- glebius@ mentioned that the sysctl interface for tcpsso also allows to specify an endpoint by a pair of IP addresses and port numbers. He will put up a review, tuexen@ will review it.
- rrs@ wants to have feedback on D35166. tuexen@ will review it and rrs@ will run some packetdrill scripts.
- glebius@ wants feedback on D35199. bz@ isn't fine with it…
Next meeting: 28 July 2022 @ 1500 UTC
