[PATCH v2 11/11] vsock_test: wait for the remote to close the connection

Before check if a send returns -EPIPE, we need to make sure the connection is closed. To do that, we use epoll API to wait EPOLLRDHUP or EPOLLHUP events on the socket. Reported-by: Jorgen Hansen Signed-off-by: Stefano Garzarella --- tools/testing/vsock/util.c | 38

[PATCH v2 10/11] vsock_test: skip read() in test_stream*close tests on a VMCI host

When VMCI transport is used, if the guest closes a connection, all data is gone and EOF is returned, so we should skip the read of data written by the peer before closing the connection. Reported-by: Jorgen Hansen Signed-off-by: Stefano Garzarella --- tools/testing/vsock/vsock_test.c | 26 +
