commit 33b8aad21ac175eba9577a73eb62b0aa141c241c upstream.
Rework the reproducer for the vrf+conntrack regression reported
by Eugene into a selftest and also add a test for ip masquerading
that Lahav fixed recently.
With net or net-next tree, the first test fails and the latter
two pass.
With 09e856d54bda5f28 ("vrf: Reset skb conntrack connection on VRF rcv")
reverted first test passes but the last two fail.
A proper fix needs more work, for time being a revert seems to be
the best choice, snat/masquerade did not work before the fix.

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.
