When a bad checksum is detected, set the send_mp_fail flag to send out the MP_FAIL option. Add a new function mptcp_has_another_subflow() to check whether there's only a single subflow. When multiple subflows are in use, close the affected subflow with a RST that includes an MP_FAIL option and discard the data with the bad checksum. Set the sk_state of the subsocket to TCP_CLOSE, then the flag MPTCP_WORK_CLOSE_SUBFLOW will be set in subflow_sched_work_if_closed, and the subflow will be closed. When a single subfow is in use, temporarily handled by sending MP_FAIL with a RST too.

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.
