Attendees: rrs@, rscheff@, thj@, tuexen@

• PR 217214, PR 218270 are closed, but NetAPP is experiencing this in stable/11 based builds. Happens during high loss scenarios. rscheff@ is still looking at it. Workaround seems to be disabling SACK.

• Have there been UDP performance improvements for UDP? In the context of TCP over UDP, some improvements to LRO might be done by rrs@. For the context of QUIC, thj@ will look into possibilities to improve it.

• Is the last bugfix for RACK also needed for the base stack. The answer is no.

• Using Compressed ACKs increases in Netflix testing the rate of TCP connections being reset. rrs@ is looking into it.

• syzkaller is finding some issues for the RACK and BBR stack. Right now tuexen@ can't reproduce them locally. tuexen@ will try different ways to reproduce them and get core dumps.

Next meeting: 07 October @ 1400 UTC
