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@.

D21011 is implementing Accurate ECN and has been updated it again and will be reviewed by rrs@ and tuexen@.

D30043 is a small whitespace cleanup.
D28822 improves PRR, needs some cleanup.
PR 263445 and
PR 264257: Both seem to have the same root cause. tuexen@ and rscheff@ are trying to figure out what that root cause is now looking at BBLog files.
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.
