Your kernel/glibc is a little older. You can enable
USE_XFRM_INTERFACE_IFLA_HEADER=true for this so libreswan uses a local

Maybe look at bugs.libreswan.org or github.com/libreswan/ for some
issues/bugs that might look managable? Otherwise look through the
source for XXX or TODO but those vary from simple to very hard :)
