Relevant bits from the previous cover letter: There are still some sporadic self-test failures for assimetric links. Looks like they are caused by retransmissions/receiver dropping packets due to MPTCP level OoO check. I'll try to address that asap, but I still consider this series for inclusion, so that it can stage a bit in the export branch. Note: the last patch re-introduces the workqueue usage for the datapath (ye= s, it makes me feel sick, sad and tired :(. I was unable to avoid it. There is weird and convoluted schema to possibly avoiding (again) the workqueue usage. If you don't feel too scaring using a fake NAPI instance to delegate actions to other mptcp subflows, I can try to cook that... Paolo Abeni (4): mptcp: always graft subflow socket to parent. mptcp: re-enable sndbuf autotune mptcp: do not queue excessive data on subflows. mptcp: schedule work for better snd subflow selection net/mptcp/protocol.c | 108 ++++++++++++++++++------------------------- net/mptcp/protocol.h | 21 +++++++++ net/mptcp/subflow.c | 13 +++++- 3 files changed, 77 insertions(+), 65 deletions(-) -- = 2.26.2 --===============6124184675826970220==--
