Attendees: rscheff@, thj@, tuexen@
Discussion
- tuexen discussed how to mitigate blackhole detection problems
- tuexen@ has a review to ensure we don't do blackhole detection once we are at the minimum value D24308; committed
- Discussion on what should trigger blackhole detection – full size? Or, even smaller messages which are above our min MTU? For at least IPv6, min MTU makes sense.
- Otherwise, tuexen@'s plan remains unchanged.
- BBR and RACK needs some modifcation
- Discussion of D24237: rscheff@ changed both the in-order and out-of-order data path so we call sorwakeup_locked() [when necessary] after the SACK blocks are updated. Still ongoing. rrs@ reviewed.
- Can the TCP_STATS framework be turned on and sample no connections? Yes. thj@ will do.
- D18892: Upcoming: PRR
- D18985: Upcoming: Rescue retransmission
- D21117: Upcoming: Reduce counter space
- D22438: Upcoming: Performance improvement for after idle
- D8253: rscheff@ will look into it.
- D10894: possibly use hystart++ instead. rrs@ will look into this later this year.
- Should TCP Fast Open support sending of SYN segments with data and the FIN bit set? Doesn't seem to be a high priority.
Next meeting: 10 September @ 1400 UTC
