This patch has not been tested since rebasing onto upstream vmtest.sh.
It is probably very broken, but here to show the direction the testing
is going in...
vsock_test uses tcp for the control socket. TCP itself responds to
namespaces. In order to test vsock but not break TCP, vmtest.sh sets up
a bridge with socat (perhaps ip tables would be better, because it can
reduce an out-of-tree tool dependency). Another option is to not use
vsock_test for the NS tests, but it seems more robust to test all of
vsock instead of just (for example) connectibility...

+# Namespace tests require to test the functionality of VSOCK under different
+# namespace configurations. Ideally, we can use vsock_test and friends under
+# the different configurations to ensure that all functionality works
+# regardless of namespace setup. vsock_test also requires TCP for its control
+# plane, which is also impacted by namespacing. For this reason, these tests
+# build a bridge between the namespaces so that the TCP control traffic can
+# flow between namespaces. The bridge setup looks as follows:
