[MPTCP] [PATCH 00/20] Forward-ports of lockless subflow establishment

[Christoph Paasch]

[-- Attachment #1: Type: text/plain, Size: 2014 bytes --]

As the fixes have now landed in mptcp_trunk, here are the forward-ports
of the lockless subflow establishment.

Tested it a bit and it seems to work fine.

Christoph Paasch (20):
  mptcp: Cleanup
  mptcp: Improved debugging
  mptcp: Use correct tcp_queue when calling mptcp_fragment
  mptcp: Use mptcp_can_new_subflow where possible
  mptcp: Render mptcp_sub_inherit_sockopts lockless
  mptcp: Make mptcp_set_new_pathindex lockless
  mptcp: Remove cnt_subflows
  mptcp: Remove cnt_established
  mptcp: Rename tw_lock to mpcb_list_lock
  mptcp: Make subflow-list an RCU-list
  mptcp: Don't take meta-lock when receiving third ACK
  mptcp: Make mptcp_do_join_short and mptcp_lookup_join lockless
  mptcp: Reset tsorted_anchor after call to tcp_fragment
  mptcp: Pick correct sk when iterating in mptcp_set_rto
  mptcp: Build-Fix
  mptcp: Reset sk_it to NULL as we keep on iterating
  mptcp: Close remaining subflows when falling back in
    mptcp_verif_dss_csum
  mptcp: Restart subflow-selection when we force a re-evaluation
  mptcp: Don't free skb when tcp_transmit_skb without cloning
  mptcp: Use spin_lock_bh where appropriate for mpcb_list_lock
