Chris Mi a93dcaada2 net: psample: Fix netlink skb length with tunnel info ... Currently, the psample netlink skb is allocated with a size that does not account for the nested 'PSAMPLE_ATTR_TUNNEL' attribute and the padding required for the 64-bit attribute 'PSAMPLE_TUNNEL_KEY_ATTR_ID'. This can result in failure to add attributes to the netlink skb due to insufficient tail room. The following error message is printed to the kernel log: "Could not create psample log message". Fix this by adjusting the allocation size to take into account the nested attribute and the padding.
