[ Upstream commitc39a6a277e] If the last test fails, the other side still completes correctly, which could lead to false positives. Let's add a final barrier that ensures that the last test has finished correctly on both sides, but also that the two sides agree on the number of tests to be performed.

AF_VSOCK test suite
-------------------
These tests exercise net/vmw_vsock/ host<->guest sockets for VMware, KVM, and
Hyper-V.
The following tests are available:
* vsock_test - core AF_VSOCK socket functionality
* vsock_diag_test - vsock_diag.ko module for listing open sockets
The following prerequisite steps are not automated and must be performed prior
to running tests:
1. Build the kernel, make headers_install, and build these tests.
2. Install the kernel and tests on the host.
3. Install the kernel and tests inside the guest.
4. Boot the guest and ensure that the AF_VSOCK transport is enabled.
Invoke test binaries in both directions as follows:
# host=server, guest=client
(host)# $TEST_BINARY --mode=server \
--control-port=1234 \
--peer-cid=3
(guest)# $TEST_BINARY --mode=client \
--control-host=$HOST_IP \
--control-port=1234 \
--peer-cid=2
# host=client, guest=server
(guest)# $TEST_BINARY --mode=server \
--control-port=1234 \
--peer-cid=2
(host)# $TEST_BINARY --mode=client \
--control-port=$GUEST_IP \
--control-port=1234 \
--peer-cid=3
