Mat Martineau says: ==================== mptcp: Userspace path manager API 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
