Mancera. 3) Fix nf_nat_register_fn() error path allowing for a memleak. 4) Revalidate ihl before calling icmp_send() in IPVS, from Julian Anastasov. 5) Hold reference on ct until flow is released to address, otherwise access to release ct->ext or different ct due to typesafe RCU semantics. 6) Use kzalloc_obj() to allocate timer object in xt_IDLETIMER as reported by sashiko to address uninitialized access. 7) Hold reference on module during netlink for cttimeout, cthelper ctnetlink and nfnetlink_acct.
