Subject: [PATCH net-next 0/8] mptcp: Add genl events for connection info

This series from the MPTCP tree adds genl multicast events that are
important for implementing a userspace path manager. In MPTCP, a path
manager is responsible for adding or removing additional subflows on
each MPTCP connection. The in-kernel path manager (already part of the
kernel) is a better fit for many server use cases, but the additional
flexibility of userspace path managers is often useful for client
devices.

Patches 1, 2, 4, 5, and 6 do some refactoring to streamline the netlink
event implementation in the final patch.

Patch 3 improves the timeliness of subflow destruction to ensure the
'subflow closed' event will be sent soon enough.

Patch 7 allows use of the GENL_UNS_ADMIN_PERM flag on genl mcast groups
to mandate CAP_NET_ADMIN, which is important to protect token information
in the MPTCP events. This is a genetlink change.

Patch 8 adds the MPTCP netlink events.


Florian Westphal (8):
  mptcp: move pm netlink work into pm_netlink
  mptcp: split __mptcp_close_ssk helper
  mptcp: schedule worker when subflow is closed
  mptcp: move subflow close loop after sk close check
  mptcp: pass subflow socket to a few helpers
  mptcp: avoid lock_fast usage in accept path
  genetlink: add CAP_NET_ADMIN test for multicast bind
  mptcp: add netlink event support
