Message-ID: <tkrat.3179a4eba4a0f5ee@s5r6.in-berlin.de> Date: Tue, 10 Mar 2009 21:01:08 +0100 (CET) From: Stefan Richter <stefanr@...6.in-berlin.de> To: linux1394-devel@...ts.sourceforge.net cc: linux-kernel@...r.kernel.org Subject: [PATCH 3/5] firewire: cdev: fix race of ioctl_send_request with bus reset The bus reset handler concurrently frees client->device->node. Use device->node_id instead. This is equivalent to device->node->node_id while device->generation is current.
