Subject: [PATCH v2 10/11] vsock_test: skip read() in test_stream*close tests on a VMCI host
Date: Thu, 1 Aug 2019 17:25:40 +0200 [thread overview]
Message-ID: <20190801152541.245833-11-sgarzare@redhat.com> (raw)
In-Reply-To: <20190801152541.245833-1-sgarzare@redhat.com>
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 <jhansen@vmware.com>
