      Bring the cluster monitor "inhouse", rather then depending on the jfed · d7c4230e

      monitoring system.
      
      New portal_monitor daemon does a GetVersion/ListResources call at each
      of the clusters every five minutes, and updates the new table in the
      DB called apt_aggregate_status. We calculate free/inuse counts for
      physical nodes and a free count for VMs. Failure to contact the
      aggregate for more then 10 minutes sets the aggregate as down, since
      from our perspective if we cannot get to it, the cluster is down.
      
      Unlike the jfed monitoring system, we are not going to try to
      instantiate a new experiment or ssh into it. Wait and see if that is
      necessary in our context.
      
      On the instantiate page, generate a json structure for each cluster,
      similar the one described in issue #172 by Keith. This way we can easily
      switch the existing code over to this new system, but fail back to the
      old mechanism if this turn out to be a bust.
      
      Some other related changes to how we hand cluster into the several web
      pages.

      Fix two bugs in skb processing in Linux ipod module. · 0e3d8b99
      David Johnson authored
      One was minor (not rolling the ip optional field length into
      pskb_may_pull check).  The second was not minor; we weren't
      appropriately calling pskb_may_pull to check if the iph + icmph + ipod secret
      was in a linear buf... and then we finally ran across a driver for which
      the ipod secret did not fully fit in the first skb buffer chunk... so
      linearization was actually necessary.
      
      Another way that has been suggested to fix the potential bugs that arise
      from linearization, the use of skb_header_pointer, isn't the most
      desireable option in this case, since it costs more stack memory *for
      each* input ICMP packet (and nearly 100% of the time, it's not an ipod
      and we don't care).
