Currently data fin on data packet are not handled properly: the 'rcv_data_fin_seq' field is interpreted as the last sequence number carrying a valid data, but for data fin packet with valid maps we currently store map_seq + map_len, that is, the next value. The 'write_seq' fields carries instead the value subseguent to the last valid byte, so in mptcp_write_data_fin() we never detect correctly the last DSS map.

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.
