[PATCH mptcp-next v14 00/25] userspace pm enhancements

[Geliang Tang <geliang.tang@linux.dev>]

v14:
 - implement flush operation in user space as Mat suggested.
 - update selftests.
 - Now this series includes five parts:

Part 1: dump for userspace pm (patches 1-9)
Part 2: fixes for creating id 0 subflow (patches 10-13)
Part 3: v4-mapped addr support (patches 14-15)
Part 4: flush for userspace pm (patches 16-18)
Part 5: address entry refcount for userspace pm (patches 19-25)

v13:
 - add 4 patches: 10, 11, 31, 32.
 - update selftests.

v12:
 - add pm_remove_subflows, instead of changing
   pm_remove_addrs_and_subflows.

v11:
 - add a patch "mptcp: userspace pm send RM_ADDR for conn_list addr" to
   fix selftests failures reported by CI.

v10:

 - add "fixes for creating id 0 subflow" part.

v9:
 - Fix typos reported by CI.
 - Squash two patches
        "selftests: mptcp: pm_netlink: print colored output"
        "selftests: mptcp: add mptcp_lib_check helper"
   into one:
        "selftests: mptcp: add mptcp_lib_check helper"

v8:
 - add mptcp_lib_check helper

v7:
 - merge 'Squash to "mptcp: add use_id parameter for addresses_equal
   v6"', fix packetdrill_add_addr error.
 - fix memleak error in "mptcp: add netlink pm addr entry refcount".
 - split "selftests: mptcp: flush and dump userspace addrs list" into
   two patches.

v6:
 - fix kmemleak errors reported by CI.
 - drop a patch "mptcp: add netlink pm addr entry refcount".

v5:
- Put the two series "add flush and dump for userspace" and
 "add refcount for address entry" together for better CI testing.

Patches 1-12: add flush and dump for userspace

v4:
 - fix the deadlock issue in v3 reported by CI.

v3:
 - fix warnings reported by CI.
 - get id_bitmap using pm_nl_get_pernet_from_msk.

v2:
 - add two patches: "mptcp: check userspace pm subflow flag"
                    "selftests: mptcp: add userspace pm subflow flag"

This series adds flush and dump commands support for userspace pm.

Patches 13-21: add refcount for address entry

v4:
 - move two patches here from "add flush and dump for userspace pm":
  mptcp: add userspace_pm_get_entry helper
  mptcp: drop addr_match and id_match

v3:
 - add four selftests patches:
  selftests: mptcp: export event macros in mptcp_lib
  selftests: mptcp: extract mptcp_lib_check_expected
  selftests: mptcp: add mptcp_lib_verify_listener_events
  selftests: mptcp: add mptcp_lib_init_ns

v2:
 - rebased with "add flush and dump for userspace pm" series.

Add refcount for address entry.
