This series includes several changes to the MPTCP RX path. The main goals are improving the RX performances, and increase the long term maintainability.
Some changes reflects recent(ish) improvements introduced in the TCP stack: patch 1, 2 and 3 are the MPTCP counter part of SKB deferral free and auto-tuning improvements. Note that patch 3 could possibly fix additional issues, and overall such patch should protect from similar issues to arise in the future.
Patches 4-7 are aimed at introducing the socket backlog usage which will be done in a later series to process the packets received by the different subflows while the msk socket is owned.
Patch 8 is not related to the RX path, but it contains additional tests for new features recently introduced in net-next.
Could be a coincidence but we got 3 simult_flows.sh flakes since this was posted. Previous one was 20+ days ago: https://netdev.bots.linux.dev/contest.html?ld_cnt=250&pw-pass=n&pass...
Thank you for this message! Our CI didn't spot this issue in the last 2 weeks. I see it happened again on NIPA (sorry for that, and thank you for having ignored this selftest) so I guess it is not a coincidence, I'm going to investigate this issue ASAP.
Cheers, Matt
