Linux kernel source tree

Mat Martineau says: ==================== Multipath TCP part 3: Multiple subflows and path management v2 -> v3: Remove 'inline' in .c files, fix uapi bit macros, and rebase. v1 -> v2: Rebase on current net-next, fix for netlink limit setting, and update .gitignore for selftest. This patch set allows more than one TCP subflow to be established and used for a multipath TCP connection. Subflows are added to an existing connection using the MP_JOIN option during the 3-way handshake. With multiple TCP subflows available, sent data is now stored in the MPTCP socket so it may be retransmitted on any TCP subflow if there is no DATA_ACK before a timeout. If an MPTCP-level timeout occurs, data is retransmitted using an available subflow. Storing this sent data requires the addition of memory accounting at the MPTCP level, which was previously delegated to the single subflow. Incoming DATA_ACKs now free data from the MPTCP-level retransmit buffer. IP addresses available for new subflow connections can now be advertised and received with the ADD_ADDR option, and the corresponding REMOVE_ADDR option likewise advertises that an address is no longer available. The MPTCP path manager netlink interface has commands to set in-kernel limits for the number of concurrent subflows and control the advertisement of IP addresses between peers. To track and debug MPTCP connections there are new MPTCP MIB counters, and subflow context can be requested using inet_diag. The MPTCP self-tests now validate multiple-subflow operation and the netlink path manager interface. ==================== 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.
