0-DAY kernel build testing backend reported: sparse warnings: (new ones prefixed by >>) >> >> net/netfilter/xt_ipcomp.c:63:26: sparse: restricted __be16 degrades to integer >> >> net/netfilter/xt_ipcomp.c:63:26: sparse: cast to restricted __be32 Fix this by using ntohs without shifting.

2013-12-24netfilter: add IPv4/6 IPComp extension match supportfan.du1-0/+111
With this plugin, user could specify IPComp tagged with certain CPI that host not interested will be DROPped or any other action. For example: iptables -A INPUT -p 108 -m ipcomp --ipcompspi 0x87 -j DROP ip6tables -A INPUT -p 108 -m ipcomp --ipcompspi 0x87 -j DROP Then input IPComp packet with CPI equates 0x87 will not reach upper layer anymore.
