Subject[PATCH v2 00/11] VSOCK: add vsock_test test suite
The vsock_diag.ko module already has a test suite but the core AF_VSOCK
functionality has no tests. This patch series adds several test cases that
exercise AF_VSOCK SOCK_STREAM socket semantics (send/recv, connect/accept,
half-closed connections, simultaneous connections).

Stefan: Do you think we should have a single application or is better to
split it in single tests (e.g. vsock_test_send_recv, vsock_test_half_close,
vsock_test_multiconnection, etc.)?

Jorgen: Please test the VMCI transport and let me know if the fixes work.
I added the '--transport' parameter to skip the read() on the half-closed
connection test.

Dexuan: Do you think can be useful to test HyperV?

The v1 of this series was originally sent by Stefan. I rebased on master
and tried to fix some issues reported by Jorgen.

- Patch 1 added by Stefan to fix header include in vsock_diag_test.
- Patch 2 added by Stefan to add SPDX identifiers. I modified it to be
aligned with SPDX currently used on master.
- Patch 3:
* fixed SPDX [Stefano].
- Patch 7:
* Drop unnecessary includes [Stefan]
* Fixed SPDX [Stefano]
* Set MULTICONN_NFDS to 100 [Stefano]
* Changed (i % 1) in (i % 2) in the 'multiconn' test [Stefano]
- Patches 8,9,10 added to skip read after close in test_stream*close tests
on a VMCI host.
- Patch 11 added to wait for the remote to close the connection, before
check if a send returns -EPIPE.
