This one passes for me.

Can you run the test with '-v -p'? -v will give you the command line
that is failing. -p will pause the tests at the failure. From there you
can do:

ip netns exec ns-A bash

Look at the routing - no VRF is involved so the address should be local
to the device and the loopback. Run the test manually to see if it
really is failing.

This one seems to be a new problem. The socket is bound to eth1 and the
address bind is to an address on loopback. That should not be working.

This failure is similar to the last one. Need to see if a recent commit
changed something.
