Subject: [PATCH ucspi-vsock] vsock_open: return fd instead of 0 on success
Date: Tue,  9 Mar 2021 17:18:16 +0000	[thread overview]
Message-ID: <> (raw)

Previously, this returned the return value of connect(2), which is 0
on success.  So stdin would be assigned to descriptors 6 and 7 in
vsockclient instead of the socket.  Oops.
