Mat Martineau says: ==================== mptcp: Add full mesh path manager option The path manager in MPTCP controls the creation of additional subflows after the initial connection is created. As each peer advertises available endpoints with the ADD_ADDR MPTCP option, the recipient of those advertisements must decide which subflows to create from the known local and remote interfaces that are available for use by MPTCP. The existing in-kernel path manager will create one additional subflow when an ADD_ADDR is received, or a local address is newly configured for MPTCP use. The maximum number of subflows has a configurable limit. This patch set adds a MPTCP_PM_ADDR_FLAG_FULLMESH flag to the MPTCP netlink API that enables subflows to be created more aggressively. When an ADD_ADDR is received from a peer, new subflows are created between that address/port and all local addresses configured for MPTCP. Similarly, when a new local address is newly configured for use by MPTCP, new subflows are created between that local address and all known remote addresses for that MPTCP connection. The configurable limit on the number of subflows still applies. If the new flag is not used the path manager behavior is unchanged. Patch 1 adds a helper function and refactors another function to prepare for the rest of the patch series. Patches 2 and 3 add two mesh connection capabilities: initiating subflows based on added local addresses, or reacting to incoming advertisements. Patches 4-6 add full mesh cases to the self tests. ==================== 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.
