Paul Moore 04f81f0154 cipso: don't use IPCB() to locate the CIPSO IP option ... Using the IPCB() macro to get the IPv4 options is convenient, but unfortunately NetLabel often needs to examine the CIPSO option outside of the scope of the IP layer in the stack. While historically IPCB() worked above the IP layer, due to the inclusion of the inet_skb_param struct at the head of the {tcp,udp}_skb_cb structs, recent commit 971f10ec ("tcp: better TCP_SKB_CB layout to reduce cache line misses") reordered the tcp_skb_cb struct and invalidated this IPCB() trick. This patch fixes the problem by creating a new function, cipso_v4_optptr(), which locates the CIPSO option inside the IP header without calling IPCB(). Unfortunately, this isn't as fast as a simple lookup so some additional tweaks were made to limit the use of this new function.
