[PATCH mptcp-next 0/3] mptcp: misc improvement

Posted by Paolo Abeni 7 months, 3 weeks ago

This series is a follow-up the the discussion ongoing here:

https://github.com/multipath-tcp/mptcp_net-next/issues/437

Daire reported several sub-optimal MPTCP behaviour on high-latency
links.

At least 3 different items stands off:

* notsent_lowat setting fooling the scheduler
* sub-optimal send buffer autotuning
* delayed acks being de-facto disabled due to subflow rcvlowat

This series is an initial attempt to address the first 2 points above.
I have a tentative patch for the 3rd, but it's nowhere near passing
the self-tests, so it will have to wait a bit.

Sending out early after very little testing.

Paolo Abeni (3):
  mptcp: consolidate sockopt synchronization
  mptcp: ignore notsent_lowat setting at the subflow level.
  mptcp: refactor sndbuf auto-tuning.
