--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().
