      ====================
      This is the second batch of Netfilter updates for net-next. It contains the
      kernel changes for the new user-space connection tracking helper
      infrastructure.
      
      More details on this infrastructure are provides here:
      http://lwn.net/Articles/500196/
      
      
      
      Still, I plan to provide some official documentation through the
      conntrack-tools user manual on how to setup user-space utilities for this.
      So far, it provides two helper in user-space, one for NFSv3 and another for
      Oracle/SQLnet/TNS. Yet in my TODO list.

      netfilter: add user-space connection tracking helper infrastructure · 12f7a505
      Pablo Neira Ayuso authored
      
      
      There are good reasons to supports helpers in user-space instead:
      
      * Rapid connection tracking helper development, as developing code
        in user-space is usually faster.
      
      * Reliability: A buggy helper does not crash the kernel. Moreover,
        we can monitor the helper process and restart it in case of problems.
      
      * Security: Avoid complex string matching and mangling in kernel-space
        running in privileged mode. Going further, we can even think about
        running user-space helpers as a non-root process.
      
      * Extensibility: It allows the development of very specific helpers (most
        likely non-standard proprietary protocols) that are very likely not to be
        accepted for mainline inclusion in the form of kernel-space connection
        tracking helpers.
      
      This patch adds the infrastructure to allow the implementation of
      user-space conntrack helpers by means of the new nfnetlink subsystem
      `nfnetlink_cthelper' and the existing queueing infrastructure
      (nfnetlink_queue).
      
      I had to add the new hook NF_IP6_PRI_CONNTRACK_HELPER to register
      ipv[4|6]_helper which results from splitting ipv[4|6]_confirm into
      two pieces. This change is required not to break NAT sequence
      adjustment and conntrack confirmation for traffic that is enqueued
      to our user-space conntrack helpers.
      
      Basic operation, in a few steps:
      
      1) Register user-space helper by means of `nfct':
      
       nfct helper add ftp inet tcp
      
       [ It must be a valid existing helper supported by conntrack-tools ]
      
      2) Add rules to enable the FTP user-space helper which is
         used to track traffic going to TCP port 21.
      
      For locally generated packets:
      
       iptables -I OUTPUT -t raw -p tcp --dport 21 -j CT --helper ftp
      
      For non-locally generated packets:
      
       iptables -I PREROUTING -t raw -p tcp --dport 21 -j CT --helper ftp
      
      3) Run the test conntrackd in helper mode (see example files under
         doc/helper/conntrackd.conf
      
       conntrackd
      
      4) Generate FTP traffic going, if everything is OK, then conntrackd
         should create expectations (you can check that with `conntrack':
      
       conntrack -E expect
      
          [NEW] 301 proto=6 src=192.168.1.136 dst=130.89.148.12 sport=0 dport=54037 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.1.136 master-dst=130.89.148.12 sport=57127 dport=21 class=0 helper=ftp
      [DESTROY] 301 proto=6 src=192.168.1.136 dst=130.89.148.12 sport=0 dport=54037 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.1.136 master-dst=130.89.148.12 sport=57127 dport=21 class=0 helper=ftp
      
      This confirms that our test helper is receiving packets including the
      conntrack information, and adding expectations in kernel-space.
      
      The user-space helper can also store its private tracking information
      in the conntrack structure in the kernel via the CTA_HELP_INFO. The
      kernel will consider this a binary blob whose layout is unknown. This
      information will be included in the information that is transfered
      to user-space via glue code that integrates nfnetlink_queue and
      ctnetlink.
