Backport hot off the press upstream netlink patch. Fixes stats display from CAKE qdisc on MIPS allowing us to bump CAKE to latest version. The gen_stats facility will add a header for the toplevel nlattr of type TCA_STATS2 that contains all stats added by qdisc callbacks. A reference to this header is stored in the gnet_dump struct, and when all the per-qdisc callbacks have finished adding their stats, the length of the containing header will be adjusted to the right value. However, on architectures that need padding (i.e., that don't set CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added before the stats, which means that the stored pointer will point to the padding, and so when the header is fixed up, the result is just a very big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS struct, this problem has been mostly invisible, but we exposed it with the netlink attribute-based statistics in CAKE. Fix the issue by fixing up the stored pointer if it points to a padding nlattr. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> |
