[XFRM]: esp: fix skb_tail_pointer conversion bug
Fix incorrect switch of "trailer" skb by "skb" during skb_tail_pointer conversion: - *(u8*)(trailer->tail - 1) = top_iph->protocol; + *(skb_tail_pointer(skb) - 1) = top_iph->protocol; - *(u8 *)(trailer->tail - 1) = *skb_network_header(skb); + *(skb_tail_pointer(skb) - 1) = *skb_network_header(skb); Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S. Miller <davem@davemloft.net>
