2019-12-20vsock_test: wait for the remote to close the connectionStefano Garzarella3-4/+48
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.

2019-12-20VSOCK: extract connect/accept functions from vsock_diag_test.cStefan Hajnoczi3-76/+119
Many test cases will need to connect to the server or accept incoming connections. This patch extracts these operations into utility functions that can be reused.

2019-12-20VSOCK: fix header include in vsock_diag_testStefan Hajnoczi3-5/+4
The vsock_diag_test program directly included ../../../include/uapi/ headers from the source tree. Tests are supposed to use the usr/include/linux/ headers that have been prepared with make headers_install instead. Suggested-by: David S.

2017-10-05VSOCK: add tools/testing/vsock/vsock_diag_testStefan Hajnoczi8-0/+1038
This patch adds tests for the vsock_diag.ko module. These tests are not self-tests because they require manual set up of a KVM or VMware guest. Please see tools/testing/vsock/README for instructions. The control.h and timeout.h infrastructure can be used for additional AF_VSOCK tests in the future. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: David S.
