Revision c38f57da428b033f2721b611d84b1f40bde674a8 authored by Stefan Hajnoczi on 06 December 2018, 19:14:34 UTC, committed by Michael S. Tsirkin on 06 December 2018, 19:22:34 UTC
If a local process has closed a connected socket and hasn't received a RST packet yet, then the socket remains in the table until a timeout expires. When a vhost_vsock instance is released with the timeout still pending, the socket is never freed because vhost_vsock has already set the SOCK_DONE flag. Check if the close timer is pending and let it close the socket. This prevents the race which can leak sockets.
