[MPTCP] [PATCH net-next 0/8] mptcp: non backup subflows pre-reqs

[Paolo Abeni <pabeni at redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 1072 bytes --]

This series contains a bunch of MPTCP improvements loosely related to
concurrent subflows xmit usage, currently under development.

The first 3 patches are actually bugfixes for issues that will become apparent
as soon as we will enable the above feature.

The later patches improve the handling of incoming additional subflows,
improving significantly the performances in stress tests based on a high new
connection rate.

Paolo Abeni (8):
  subflow: always init 'rel_write_seq'
  mptcp: avoid data corruption on reinsert
  mptcp: mark as fallback even early ones
  mptcp: explicitly track the fully established status
  mptcp: cleanup subflow_finish_connect()
  subflow: explicitly check for plain tcp rsk
  subflow: use rsk_ops->send_reset()
  subflow: introduce and use mptcp_can_accept_new_subflow()
