====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

1) Update conncount to use the original tuple after ct lookup to ensure
   consistent counting, from Fernando F. Mancera.

2) Remove redundant net_device field in info structure that helps
   parse the flowtable path discovery.

3) Move net_device to flowtable check to the flowtable discovery
   path parser. This is preparation work to pass the tunnel dst_entry
   via .fill_forward_path.

4) Update DSA .fill_forward_path to break at the user DSA, since
   the conduit DSA is not used in the datapath. This slighly simplifies
   the flowtable path discovery parser.

5) Do not advance index in the path stack prematurely, otherwise
   it points to uninitialized slots on error. Not an issue currently
   but it could be once tunnel dst_entry is passed via .fill_forward_path.

6) Pass the tunnel dst_entry via dev_fill_forward_path().

7) Update ipip and ip6ip6 tunnels to pass the dst_entry through
   dev_fill_forward_path().

8) Call skb_valid_dst() before accessing skb_dst() to ensure dst_entry
   is not a template.

9) Use UNACK timeout when RST packet does not match the expected
   window while in ESTABLISHED state, the existing approach the CLOSE
   state timeout which is only 10 seconds. Adopt a more conservative
   timeout by default for this case.

* tag 'nf-next-26-07-31' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next:
  netfilter: conntrack: tcp: use UNACK timeout for non-closing RST packets
  netfilter: nf_tables: call skb_valid_dst() before skb_dst()
  netfilter: flowtable: release tunnel route on error when building forward path
  net: pass dst via net_device_path in dev_fill_forward_path()
  net: do not advance stack index from dev_fwd_path()
  net: dsa: stop at the user device in .fill_forward_path
  netfilter: flowtable: consolidate flowtable device check
  netfilter: flowtable: consolidate net_device field in nft_forward_info struct
  netfilter: conncount: normalize tuple and zone on successful ct lookup
