Setup phase in test_port_shadow() relied upon a race-condition:
Listening nc on port 1405 was started in background before attempting to
create the fake conntrack entry using the same source port. If listening
nc won, fake conntrack entry could not be created causing wrong
behaviour. Reorder nc calls to fix this and introduce a short delay
before testing the setup to wait for listening nc process startup.

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.
