      Allow slightly altered tb-fix-node syntax for creating jails on local · d564e0fb
      Leigh B. Stoller authored
      nodes. The second argument can now be an NS node instead of the name
      of a real testbed node. For example:
      
      	tb-set-hardware $node3  pc600
      	tb-set-hardware $nodev1 pcvm600
      	tb-fix-node $nodev1 $node3
      
      So, "fix" $nodev1 to $node3. The intent is that once $node3 is
      allocated by assign to a real testbed node, we can then allocate a
      virtual node on pcXX to $nodev1. I did this primarily to allow for
      easy testing of jails via my NS file, without having to hack assign
      wrapper to deeply. Note there are still hacks in assign_wrapper to
      support this, but they are not extensive.
      
      Also my old usewatunnels stuff I never checked in:
      
      	tb-set-usewatunnels 0/1

      NSE related changes: · 05bc3bd4
      Shashi Guruprasad authored
        - Fixes the routing problem
        - A new type "sim" has been created but not in the DB. node_types and
          nodes remain unchanged. This will change after we figure out how
          to represent in the DB the local multiple virtnodes in one phynode case
          The frontend tb_compat.tcl adds the sim type and ptopgen associates
          a huge number of sim nodes to all local PCs.
        - All simulated nodes go into one pc untill I finish coding the distributed
          nse case. Also, sim nodes go through assign but with an explicit
          "fix-node" directive in the top file. A random free pc is chosen using
          the avail script in assign_wrapper. If we don't fix node it, assign
          maps sim nodes to multiple phy nodes even when a valid all to one
          mapping is possible.
        - Syntax for nse:
      
         $ns make-simulated {
      
             set simnode1 [$ns node]
             set simnode2 [$ns node]
      
         }
         ...
      
         The old syntax
      
         set nsenode [$ns nsenode]
         $nsenode make-simulated {
         }
      
         is deprecated
      
        - All 38 frontend tests in the testsuite pass
      
        - A new table v2pmap has been added to handle multiple virt nodes to
          one phy node mapping. This is used in "tmcc hostnames" currently.
      
        - The phy node that is picked to run nse is loaded with a custom image
          FBSD45-NSE . This can use the default FBSD kernel if there is a mechanism
          to run at 1000HZ, have options IPFIREWALL_FORWARD and PERFMON turned on.
          The image is in the 'testbed' group. Do not delete this image.
      
        - Static routes now adds routes for the case dst == nexthop. The routing
          graph would be disconnected otherwise and I need to traverse this in
          assign_wrapper for nse. On the client side, such a route is filtered out in
          libsetup.pm
      
        - sim nodes are also correctly visualized

      Add new NS program object. This syntax is different than I had · b9ba3398
      Leigh B. Stoller authored
      originally anticipated, but I was worried about confusion with the
      Agent/Application API that NS provides, and which is substantially
      different than this. Anyway, I added support for this syntax:
      
      	set prog0 [$ns program]
      	$prog0 set node $nodeA
      	$prog0 set command "/bin/ls -lt >& /users/stoller/logs/foo"
      
      Kinda obvious, although whats not obvious is that without events to
      start and stop them, these will never run. So, I added support for
      this:
      
      	$ns at 10 "$prog0 start"
      	$ns at 20 "$prog0 stop"
      
      You can start and stop programs as much as you like, but you cannot
      start a program that is already running; you have to stop it first.
      You can also issue these dynamically using the same api:
      
      	tevc -e testbed/Tevents now prog0 start \
      		"command=/bin/ls -lt / >& /users/stoller/logs/foo"
      	tevc -e testbed/Tevents now prog0 stop
      
      Note the quotes when using a multiword command. I also had intened to
      support a KILL command so that you could send arbitrary signals to a
      process. I added that, but I will not bother to document it yet; since
      I invoke /bin/csh to process the command line, the issue of signals is
      a little fuzzy. Sending a signal like -HUP to the parent process (the
      csh) is not really what we want to do. I think we can support this,
      but I need to poke around and see what the right way is.

      node.tcl: Run agent-attach through the node so that we can record · deb7b404
      Leigh B. Stoller authored
      which agents are attached to which node, so that we can assign
      portnumbers to them. Also add code to updating the DB with these
      agents (virt_trafgens).
      
      sim.tcl: Get rid of $pid_$eid_events (per experiment events table),
      and replace with global eventlist table. Revisit this later, since it
      was causing problems and we do not really have a problem right now.
      Maybe later.
      
      traffic.tcl: Add virt_trafgens DB table update code. Get rid of oskit
      based traffic generators and replace with FreeBSD nodes, which will
      boot up and check if they are traffic gen source. Add get_params call,
      called by the event code im sim.tcl to get the current params for the
      START event.
