Steve Wise d53ec8af56 RDMA/iwcm: Don't copy past the end of dev_name() string ... We now use dev_name(&ib_device->dev) instead of ib_device->name in iwpm messages. The name field in struct device is a const char *, where as ib_device->name is a char array of size IB_DEVICE_NAME_MAX, and it is pre-initialized to zeros. Since iw_cm_map() was using memcpy() to copy in the device name, and copying IWPM_DEVNAME_SIZE bytes, it ends up copying past the end of the source device name string and copying random bytes. This results in iwpmd failing the REGISTER_PID request from iwcm. Thus port mapping is broken. Validate the device and if names, and use strncpy() to inialize the entire message field.
