Hi all, I think the following code in fib6_del_route in the latest kernel is useless. 1125 if (fn->leaf == NULL && fn->fn_flags&RTN_TL_ROOT) 1126 fn->leaf = &ip6_null_entry;
ip6_null_entry will never be unlinked from fn->leaf now, that is, fn->leaf == NULL will never meet. In previous kernel, When adding a default route, ip6_null_entry will be unlinked from fn->leaf. So, when deleting a default route, it need to check whether the deleted route is the last one, if so, ip6_null_entry will link to fn->leaf again. I am not sure if there is another place unlinks ip6_null_entry from fn->leaf.
