The Multipath-TCP standard (RFC 8684) says that an MPTCP host should send a TCP reset if the token in a MP_JOIN request is unknown. At this time we don't do this, the 3whs completes and the 'new subflow' is reset afterwards. There are two ways to allow MPTCP to send the reset. 1. override 'send_synack' callback and emit the rst from there. The drawback is that the request socket gets inserted into the listeners queue just to get removed again right away. 2. Send the reset from the 'route_req' function instead. This avoids the 'add&remove request socket', but route_req lacks the skb that is required to send the TCP reset. Instead of just adding the skb to that function for MPTCP sake alone, Paolo suggested to merge init_req and route_req functions. This saves one indirection from syn processing path and provides the skb to the merged function at the same time. 'send reset on unknown mptcp join token' is added in next patch.

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.
