[RFC PATCH 0/2] mptcp: never shrink offered window

Posted by Paolo Abeni 2 years ago

There patches are part of a somewhat largish series to implement
more strict RFC compliance for the MPTCP-level congestion window
handling, solving some tput instability issues.

The obtain the above we need to modify an existing MPTCP hook,
touching the TCP code (in patch 1/2), ence the RFC.

The later patch demonstrates the actual usage of such hook.

Paolo Abeni (2):
  tcp: allow MPTCP to update the announced window.
  mptcp: never shrink offered window
