Tobias Brunner 8a6f9ba70e kernel-netlink: Don't fallback to peer address as gateway/nexthop
This doesn't really seem useful (perhaps it was before we started to
configure the outbound interface on our routes). And it can actually
cause the route installation to fail e.g. for routes over point-to-point
interfaces where we'd get "Error: Nexthop has invalid gateway" errors.

Note that we can't return NULL if we find an interface as e.g. the updown
plugin uses this method to determine the outbound interface (it ignores
the nexthop), which it passes to the script.  If we returned NULL, it
would pass "unknown" instead, which would cause the firewall rules to
mismatch.  While it seems that 0.0.0.0/:: is ignored as nexthop by the
kernel on the installed route, I still explicitly ignore such addresses
to avoid any unintended side-effects.

The automatic route installation in the ikev2/shunt-manual-prio scenario
had to be disabled on the clients.  The reason is that the route in table
220 won't have a nexthop set (the peers are directly connected), so when
trying to reach alice or venus via SSH, which matches the port-specific
bypass policies for which we don't install throw routes, the hosts will
do ARP requests for the target IPs instead of routing the packets via
moon.

                 ------------------------------
                  strongSwan Integration Tests

   4. Manual testing


1. Building the testing environment
   --------------------------------

The testing environment can be built with the "make-testing" script after
adjusting the variables in the testing.conf file.  By default everything is
built when executing the script.  Setting any of the ENABLE_BUILD_* variables
in the configuration file to "no" will not build those parts.


2. Starting up the testing environment
   -----------------------------------

When the strongSwan testing environment has been put into place by running
the "make-testing" script you are ready to start up the KVM instances by
executing the "start-testing" script.


3. Running the automated tests
   ---------------------------

The script

    ./do-tests <testnames>

runs the automated tests.  If the <testnames> argument is omitted all tests
are executed, otherwise only the tests listed will be run as shown in the
example below:

    ./do-tests ikev2/net2net-psk ikev2/net2net-cert

Each test is divided into the following phases:

    * Load the test-specific guest configuration if any is provided.

    * Next the "pretest.dat" script found in each test directory is executed.
      Among other commands, strongSwan is started on the IPsec hosts.

    * The "evaltest.dat" script evaluates if the test has been successful.

    * The "posttest.dat" script terminates the test e.g. by stopping
      strongSwan on the IPsec hosts.  It is also responsible to cleaning up
      things (e.g. firewall rules) set up in "pretest.dat".

    * Restore the default configuration on every host (new files have to be
      deleted manually in "posttest.dat").

The test results and configuration files for all tests are stored in a
folder labeled with the current date and time in the $TESTRESULTSDIR directory.

The same results are also automatically transferred to the Apache server
running on guest "winnetou" and can be accessed via the URL

    http://192.168.0.150/testresults/


4. Manual testing
   --------------

Instead of running tests automatically with "do-tests" it is possible to
preload a test scenario with the script:

    scripts/load-testconfig <testname>

Individual configuration files can be changed and any command can be executed by
logging into a guest host directly (via SSH or a console window).  No password
is required to login as root.  The sources for every software built during
"make-testing" are mounted at /root/shared/, which allows you to change and
recompile these components.

After you have finished testing, the default configuration can be restored
with the following command (newly created files have to be deleted manually)

    scripts/restore-defaults
