[PATCH net-next 00/13] mptcp: Userspace path manager API
Posted by Mat Martineau 1 week, 5 days ago
Userspace path managers (PMs) make use of generic netlink MPTCP events
and commands to control addition and removal of MPTCP subflows on an
existing MPTCP connection. The path manager events have already been
upstream for a while, and this patch series adds four netlink commands
for userspace:

* MPTCP_PM_CMD_ANNOUNCE: advertise an address that's available for 
additional subflow connections.

* MPTCP_PM_CMD_REMOVE: revoke an advertisement

* MPTCP_PM_CMD_SUBFLOW_CREATE: initiate a new subflow on an existing MPTCP 
connection

* MPTCP_PM_CMD_SUBFLOW_DESTROY: close a subflow on an existing MPTCP 
connection

Userspace path managers, such as mptcpd, can be more easily customized
for different devices. The in-kernel path manager remains available to
handle server use cases.


Patches 1-3 update common path manager code (used by both in-kernel and
userspace PMs)

Patches 4, 6, and 8 implement the new generic netlink commands.

Patches 5, 7, and 9-13 add self test support and test cases for the new
path manager commands.
