+-Subject: [PATCH nf 2/2] netfilter: use actual socket sk rather than skb sk when routing harder
+-Date: Thu, 29 Oct 2020 03:56:06 +0100
+-Message-ID: <20201029025606.3523771-3-Jason@zx2c4.com> (raw)
+-In-Reply-To: <20201029025606.3523771-1-Jason@zx2c4.com>
+-
+-If netfilter changes the packet mark when mangling, the packet is
+-rerouted using the route_me_harder set of functions. Prior to this
+-commit, there's one big difference between route_me_harder and the
+-ordinary initial routing functions, described in the comment above
+-__ip_queue_xmit():
+-
+- /* Note: skb->sk can be different from sk, in case of tunnels */
+- int __ip_queue_xmit(struct sock *sk, struct sk_buff *skb, struct flowi *fl,
+-
+-That function goes on to correctly make use of sk->sk_bound_dev_if,
+-rather than skb->sk->sk_bound_dev_if. And indeed the comment is true: a
+-tunnel will receive a packet in ndo_start_xmit with an initial skb->sk.
+-It will make some transformations to that packet, and then it will send
+-the encapsulated packet out of a *new* socket. That new socket will
+-basically always have a different sk_bound_dev_if (otherwise there'd be
+-a routing loop). So for the purposes of routing the encapsulated packet,
+-the routing information as it pertains to the socket should come from
+-that socket's sk, rather than the packet's original skb->sk. For that
+-reason __ip_queue_xmit() and related functions all do the right thing.
+-
+-One might argue that all tunnels should just call skb_orphan(skb) before
+-transmitting the encapsulated packet into the new socket. But tunnels do
+-*not* do this -- and this is wisely avoided in skb_scrub_packet() too --
+-because features like TSQ rely on skb->destructor() being called when
+-that buffer space is truely available again. Calling skb_orphan(skb) too
+-early would result in buffers filling up unnecessarily and accounting
+-info being all wrong. Instead, additional routing must take into account
+-the new sk, just as __ip_queue_xmit() notes.
+-
+-So, this commit addresses the problem by fishing the correct sk out of
+-state->sk -- it's already set properly in the call to nf_hook() in
+-__ip_local_out(), which receives the sk as part of its normal
+-functionality. So we make sure to plumb state->sk through the various
+-route_me_harder functions, and then make correct use of it following the
+-example of __ip_queue_xmit().
