Re: [libvirt] [PATCH] Fix bug libvirt daemon segfault when new force console vm session break down existed console session. When force console vm command arrived, libvirtd will break down existed console session, and in this procedure, it will call daemonStreamEvent() to release resources , so daemonStreamFilter() need to check if stream filter existed when get client object lock and client->privData's lock, if not existed, just return -1
