Can we prevent that somehow? Document that nftnl_rule_list_free() pairs with nftnl_rule_list_alloc() :-) I don't think its an issue. We could add a 'bool make_free_no_op' to nftnl_rule_list and set that to true for nftnl_rule_list structures that are allocated indirectly on behalf of nftnl_chain struct, but I think thats taking things too far. > A more fool-proof (but somewhat tedious) solution would be to duplicate > nftnl_rule_list API for use on an nftnl_chain.
