commit 535d620ea5ff1a033dc64ee3d912acadc7470619 upstream.
Address family of server side mismatches with that of client side, like
in "userspace pm add & remove address" test:
userspace_pm_add_addr $ns1 10.0.2.1 10
userspace_pm_rm_sf $ns1 "::ffff:10.0.2.1" $SUB_ESTABLISHED
That's because on the server side, the family is set to AF_INET6 and the
v4 address is mapped in a v6 one.
This patch fixes this issue. In mptcp_pm_nl_subflow_destroy_doit(), before
checking local address family with remote address family, map an IPv4
address to an IPv6 address if the pair is a v4-mapped address.
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/387
Fixes: 702c2f646d ("mptcp: netlink: allow userspace-driven subflow establishment")

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.
