      Overview: Add Event Groups: · ed964507

      	set g1 [new EventGroup $ns]
      	$g1 add  $link0 $link1
      	$ns at 60.0 "$g1 down"
      
      See the new advanced tutorial section on event groups for a better
      example.
      
      Changed tbreport to dump the event groups table when in summary mode.
      At the same time, I changed tbreport to use the recently added
      virt_lans:vnode and ip slots, decprecating virt_nodes:ips in one more
      place. I also changed the web interface to always dump the event and
      event group summaries.
      
      The parser gets a new file (event.tcl), and the "at" method deals with
      event group events by expanding them inline into individual events
      sent to each member. For some agents, this is unavoidable; traffic
      generators get the initial params in the event, so it is not possible
      to send a single event to all members of the group. Same goes for
      program objects, although program objects do default to the initial
      command now, at least on new images.
      
      Changed the event scheduler to load the event groups table. The
      current operation is that the scheduler expands events sent to a
      group, into a set of distinct events sent to each member of the
      group. At some point we proably want to optimize this by telling the
      agents (running on the nodes) what groups they are members of.
      
      Other News: Added a "mustdelay" slot to the virt_lans table so the
      parser can tell assign_wrapper that a link needs to be delayed, say if
      there are events or if the link is red/gred. Previously,
      assign_wrapper tried to figure this out by looking at the event list,
      etc. I have removed that code; see database-migrate for instructions
      on how to initialize this slot in existing experiments. assign_wrapper
      is free to ignore or insert delays anyway, but having the parser do
      this makes more sense.
      
      I also made some "rename" changes to the parser wrt queues and lans
      and links. Not really necessary, but I got sidetracked (for several
      hours!) trying to understand that rename stuff a little better, and
      now I do.

      Add a "raw" hash type ("-D raw"). Doesn't compute and compare hashes vs. · c6c4a847
      Mike Hibler authored
      a signature file, rather it compares the actual data in the image file vs.
      what is on a disk.  Mostly a debugging option, trying to find the source
      of a disk corruption problem when loading images with FBSD 4.10.
      
      Teach it about relocations, and (optionally) have it not compute hashes
      for blocks which involve relocations, since those areas will likely always
      differ in the image and disk.  The default behavior is to have it look at
      everything as before, use -N to have it skip relocation areas.

      1. Better control net detection. · ff2335dd
      Mike Hibler authored
         No longer rely on looking at kernel boot time messages and extracting
         a hardware signature to determine the nodetype to then determine the
         control net.  Now we just DHCP on all interfaces and decree that the
         interface that answers is our control net interface.
      
         An extraordinary number of sleezy tricks were needed to get FBSD4,
         FBSD5, and RHL to DHCP on all interfaces without changing any standard
         scripts.
      
         For now, the nodetype/cpuspeed/chipset scripts still exist for the
         benefit of healthd, which uses the output of nodetype to determine
         what kernel module to load.  We should fix this.
      
         Side-effect: pump, the old RHL DHCP client, is history!  For older
         RHL releases, you will need a version of dhclient.
      
         Side-effect: in Linux, all non-control net interfaces are left up
         but without a legit IP address.  This is a consequence of dhclient.
         In FBSD, it was trivial to clean this up, RHL will take a little
         more work.  Up or down, it shouldn't matter.
      
      2. Add an mfs-install make target, a scaled-down version of the client
         install.  Added a mandatory DESTDIR check so you don't accidentally
         install in the wrong place on boss.

      Split off the feedback metric gathering, alerting, and reporting code from
      slothd and slammed it into a new daemon: canaryd.  There is currently quite
      a bit of code duplication between slothd and canaryd.  Sometime in the future
      I need to go back and extract the common portions into a module.
