Krasnov Arseniy Vladimirovich e89600ebee af_vsock: SOCK_SEQPACKET broken buffer test
Add test where sender sends two message, each with own
data pattern. Reader tries to read first to broken buffer:
it has three pages size, but middle page is unmapped. Then,
reader tries to read second message to valid buffer. Test
checks, that uncopied part of first message was dropped
and thus not copied as part of second message.

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
