[MPTCP] [MPTCP][PATCH v5 mptcp-next 0/3] mptcp: retransmit ADD_ADDR when timeout and others

[Geliang Tang <geliangtang at gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 1126 bytes --]

v5:
 - add mptcp_pm_should_add_signal check
 - use list_splice_init instead of list_move
 - reuse lookup_anno_list_by_saddr
 - reuse mptcp_pm_del_add_timer
 - add new helper sk_stop_timer_sync
 - this patchset deponds on my two little squash-to patches:
  Squash-to: "mptcp: remove addr and subflow in PM netlink" Part 3
  Squash-to: "mptcp: implement mptcp_pm_remove_subflow" Part 2

v4:
 - split in two patches
 - fix racy issues

v3:
 - use timer.
 - drop bh_lock_sock.
 - move __sock_put at the end of mptcp_pm_add_timer.

v2:
 - Use delayed_work instead of timer.
 - This patch depends on my another patch named 'Squash-to: "mptcp: remove
   addr and subflow in PM netlink"'.

Geliang Tang (3):
  mptcp: add struct mptcp_pm_add_entry
  mptcp: add sk_stop_timer_sync helper
  mptcp: retransmit ADD_ADDR when timeout
