[ Upstream commit 04fac2cae9422a3401c172571afbcfdd58fa5c7e ]
When these two options had to be sent -- which is not common -- the DSS
size was not being taken into account in the remaining size.
Additionally in this situation, the reported size was only the one of
the MP_FAIL which can cause issue if at the end, we need to write more
in the TCP options than previously said.
Here we use a dedicated variable for MP_FAIL size to keep the
WARN_ON_ONCE() just after.
Fixes: c25aeb4e0953 ("mptcp: MP_FAIL suboption sending")

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.
