rtnl: fix info leak on RTM_GETLINK request for VF devices Initialize the mac address buffer with 0 as the driver specific function will probably not fill the whole buffer. In fact, all in-kernel drivers fill only ETH_ALEN of the MAX_ADDR_LEN bytes, i.e. 6 of the 32 possible bytes. Therefore we currently leak 26 bytes of stack memory to userland via the netlink interface. Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
