The to-be-transmitted data is enqueued to a subflow only when the send window is open, keeping the subflows xmit queue shorter and allowing for faster switch-over. The above requires a more accurate msk socket state tracking and some additional infrastructure to allow pushing the data pending in the msk xmit queue as soon as the MPTCP's send window opens (patches 6-10). As a side effect, the MPTCP socket could enqueue data to subflows after close() time - to completely spooling the data sitting in the msk xmit queue. Dealing with the requires some infrastructure and core TCP changes (patches 1-5) Finally, patches 11-12 introduce a more accurate tracking of the other end's receive window. Overall this refactor the MPTCP xmit path, without introducing new features - the new code is covered by the existing self-tests. v2 -> v3: - rebased, - fixed checkpatch issue in patch 1/13 - fixed some state tracking issues in patch 8/13 v1 -> v2: - this is just a repost, to cope with patchwork issues, no changes at all ==================== Link: https://lore.kernel.org/r/cover.1605458224.git.pabeni@redhat.com Signed-off-by: Jakub Kicinski --- 72308ecbf33b145641aba61071be31a85ebfd92c
