Since the nlattr header is 4 bytes in size, it can cause the netlink attribute payload to not be 8-byte aligned. This is particularly troublesome for IFLA_STATS64 which contains 64-bit statistic values. Solve this by creating a dummy IFLA_PAD attribute which has a payload which is zero bytes in size. When HAVE_EFFICIENT_UNALIGNED_ACCESS is false, we insert an IFLA_PAD attribute into the netlink response when necessary such that the IFLA_STATS64 payload will be properly aligned. With help and suggestions from Eric Dumazet. Signed-off-by: David S. Miller <davem@davemloft.net> |
