      ====================
      Netfilter updates for net-next
      
      The following patchset contains Netfilter updates for net-next, they are:
      
      1) A couple of cleanups for the netfilter core hook from Eric Biederman.
      
      2) Net namespace hook registration, also from Eric. This adds a dependency with
         the rtnl_lock. This should be fine by now but we have to keep an eye on this
         because if we ever get the per-subsys nfnl_lock before rtnl we have may
         problems in the future. But we have room to remove this in the future by
         propagating the complexity to the clients, by registering hooks for the init
         netns functions.
      
      3) Update nf_tables to use the new net namespace hook infrastructure, also from
         Eric.
      
      4) Three patches to refine and to address problems from the new net namespace
         hook infrastructure.
      
      5) Switch to alternate jumpstack in xtables iff the packet is reentering. This
         only applies to a very special case, the TEE target, but Eric Dumazet
         reports that this is slowing down things for everyone else. So let's only
         switch to the alternate jumpstack if the tee target is in used through a
         static key. This batch also comes with offline precalculation of the
         jumpstack based on the callchain depth. From Florian Westphal.
      
      6) Minimal SCTP multihoming support for our conntrack helper, from Michal
         Kubecek.
      
      7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from Florian
         Westphal.
      
      8) Fix several checkpatch errors in bridge netfilter, from Bernhard Thaler.
      
      9) Get rid of useless debug message in ip6t_REJECT, from Subash Abhinov.

      Merge branch 'ipv6-auto-flow-labels' · 17f901e8

      ====================
      ipv6: Turn on auto IPv6 flow labels by default
      
      BSD (MacOS) has already turned on flow labels by default and this does
      not seem to be causing any problems in the Internet. Let's go ahead
      and turn them on by default. We'll continue to monitor for any devices
      start choking on them.
      
      Flow labels are important since they are the desired solution for
      network devices to perform ECMP and RSS (RFC6437 and RFC6438).
      Traditionally, devices perform a 5-tuple hash on packets that
      includes port numbers. For the most part, these devices can only
      compute 5-tuple hashes for TCP and UDP. This severely limits our ability
      to get good network load balancing for other protocols (IPIP, GRE,ESP,
      etc.), and hence we are limited in using other protocols. Unfortunately,
      this method is accepted as the de facto standard to the extent that
      there are several proposals to encapsulate protocols in UDP _just_ for
      the purposes for getting ECMP to work. With hosts generating flow labels
      and devices taking them as input into ECMP (several already do), we can
      start to fix this fundamental problem.
      
      This patch set:
       - Changes IPV6_FLOWINFO sockopt to be opt-out of flow labels for
         connections rather than opt-in
       - Disable flow label state ranges sysctl by default
       - Enable auto flow labels sysctl by default
      
      v2:
        - Added functions to create an skb->hash based on flowi4 and flowi6.
          These are called in output path when creating a packet
        - Call skb_get_hash_flowi6 in ip6_make_flowlabel
        - Implement the auto_flowlabels sysctl as a mode for auto flowlabels.
          There are four modes which correspond to flow labels being enabled
          and whether socket option can be used to opt in or opt out of
          using them

      Initialize auto_flowlabels to one. This enables automatic flow labels,
      individual socket may disable them using the IPV6_AUTOFLOWLABEL socket
      option.

      ipv6: Disable flowlabel state ranges by default · be26849b
      Tom Herbert authored
      Per RFC6437 stateful flow labels (e.g. labels set by flow label manager)
      cannot "disturb" nodes taking part in stateless flow labels. While the
      ranges only reduce the flow label entropy by one bit, it is conceivable
      that this might bias the algorithm on some routers causing a load
      imbalance. For best results on the Internet we really need the full
      20 bits.
