2014-09-30be2iscsi: check ip buffer before copyingMike Christie1-5/+8
Dan Carpenter found a issue where be2iscsi would copy the ip from userspace to the driver buffer before checking the len of the data being copied: http://marc.info/?l=linux-scsi&m=140982651504251&w=2 This patch just has us only copy what we the driver buffer can support.
