Mat Martineau says: ==================== 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. ==================== 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.
