parentnetfilter: fix two recent sysctl problems (diff)
ipsec: Interfamily IPSec BEET
Here's a revised version, based on Herbert's comments, of a fix for the ipv6-inner, ipv4-outer interfamily ipsec beet mode. It fixes the network header adjustment in interfamily, and doesn't reserve space for the pseudo header anymore when we have ipv6 as the inner family.
