      Updated nse.patch,tbnexthop.{cc,h} with all the recent nse changes. · fc580b5a
      Shashi Guruprasad authored
      tbnexthop.{cc,h} now contains setsockopts to install "ipfw fwd" rules.
      
      <netinet/ip_fw.h> has changed from FBSD 4.3 to 4.5 . Because boss has 4.3,
      compiling ipfw code on boss and running it on an experimental
      node doesn't work. Therefore, I now have a cvs checked in local copy of
      the 4.5 version of the file.
      
      nseinput.tcl now finds the CPU cycle speed from /var/run/dmesg.boot and
      passes the info to nse's RT scheduler which keeps track of real time
      using the TSC. The same info can be obtained by PERFMON ioctls but the
      kernel boot time measurement of the cpu cycle speed is more accurate than
      what perfmon can report

      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

      but it really should make the user an admin, whoever it is. Non-admins
      were not able to clear out old expts in the testdb properly before.

      to a node_id. This table is used by tmcc hostnames to get the mapping.
