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.

D6656: Get gallatin@ involved. What needs to be done to also support IPv6?
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.
