NOTRACK makes all cpus share a cache line on nf_conntrack_untracked twice per packet. This is bad for performance. __read_mostly annotation is also a bad choice. This patch introduces IPS_UNTRACKED bit so that we can use later a per_cpu untrack structure more easily. A new helper, nf_ct_untracked_get() returns a pointer to nf_conntrack_untracked. Another one, nf_ct_untracked_status_or() is used by nf_nat_init() to add IPS_NAT_DONE_MASK bits to untracked status. nf_ct_is_untracked() prototype is changed to work on a nf_conn pointer.

After commit 7fee226a (net: add a noref bit on skb dst), its wrong to use : dst_release(skb_dst(skb)), since we could decrement a refcount while skb dst was not refcounted. We should use skb_dst_drop(skb) instead. Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Replace the runtime oif name resolving by netdevice notifier based resolving. When an oif is given, a netdevice notifier is registered to resolve the name on NETDEV_REGISTER or NETDEV_CHANGE and unresolve it again on NETDEV_UNREGISTER or NETDEV_CHANGE to a different name.

Since Xtables is now reentrant/nestable, the cloned packet can also go through Xtables and be subject to rules itself. Signed-off-by: NJan Engelhardt <jengelh@medozas.de> Signed-off-by: NPatrick McHardy <kaber@trash.net>

xt_TEE can be used to clone and reroute a packet. This can for example be used to copy traffic at a router for logging purposes to another dedicated machine.
