      Support 64-bit FreeBSD on the server side. · 9036d314
      Mike Hibler authored
      NOTE: currently only for FreeBSD 7.3 installs because that is the only
      set of boss/ops/fs packages I have built so far!
      
      This mostly involved minor changes to event agents. Too often we were
      passing a pointer to a "long" to *get_int32, which on a 64-bit x86 OS would
      fill the wrong half of a 64-bit variable. There was also one instance of
      TCL code that had to be tweaked to account for 32- vs 64-bit.
      
      These changes also required regeneration of SWIG stubs and an ugly change
      to the SWIG generated code to use va_copy rather than direct assignment in
      a couple of places.
      
      Also related to SWIG is ensuring that the components that go into the
      perl/python stub .so files are built with PIC. The amd64 linker requires
      this.
      
      The meta-ports had to be changed to reflect that linuxthreads and
      ulsshxmlrpcpp don't work on amd64. The former had little effect as we
      had mostly eliminated uses of linuxthreads already. The one thing that
      did change was that we do not build nfstrace on amd64 (and we don't
      currently use this anyway). Removing ulsshxmlrpcpp required switching
      to the new event scheduler (event/new_sched) that Ryan did awhile back.
      Note that it is only "new" in the sense that it uses a standard XMLRPC
      package, there should be no functional differences. However, to be safe
      we only use new_sched as the standard scheduler on 64-bit server installs.
      
      Finally, added support to elabinelab setup to do a 64-bit server install.
      Just specify FBSD73-64-STD as the boss/ops/fs osid and rc.mkelab should
      do the rest.
      
      That is pretty much it other than some random nits here and there.

      This commit adds some simple support for using the Infiniband on the · 997b21b5
      Leigh B Stoller authored
      Probe Cluster. The problem is that the IFB is a shared network that
      every node attaches to, which can looks like an ethernet device that
      can ifconfig'ed. In other words, one big lan.
      
      But we still want the user to be able to create a lan so that they can
      interact with it in thei NS file like any other network.
      
      The NS syntax is:
      
      	set lan2 [$ns make-lan "node1 node2 node3" * 0ms]
      	tb-set-switch-fabric $lan2 "infiniband"
      
      The switch fabric tells the backend to do IP assignment for the
      specific global network. Yes, I tried to be a little but general
      purpose. Lets see how this actually turns out.
      
      This first commit treats the fabric as a single big lan on the same
      subnet.
      
      NOTE 1: Since the unroutable IP space is kinda small, but the Probe
      Cluster is really big, we can easily run out of bits if we tried to do
      assignment on virtual topos. Instead, fabrics get their IP allocation
      at swapin time, and the allocations are deleted when the experiment is
      swapped out. The rationale is that the number of swapped in
      experiments is much much smaller then the number of possible topos
      that can be loaded into the DB. Still might run out, but less likely.
      
      The primary impact of above is that IP assignments can change from
      one swap to another, but this is easy to deal with if the user is
      scripting their experiment; the IP allocation is available via the
      XMLRPC interface.
      
      NOTE 2: The current code allocates from a single big network, which
      makes it easy for users to mess each other up if they start doing
      things by hand. Ultimately, we want each lan in each experinent to use
      their own subnet, but that is going to take more work, so lets do it
      in the second phase.
      
      The definition of "network fabrics" is in the new network_fabrics
      tables. As an example for probe:
      
      	INSERT INTO `network_fabrics` set
      		idx=NULL,
      		name='ifband',
      		created=now(),
      		ipalloc=1, ipalloc_onenet=1,
      		ipalloc_subnet='192.168.0.0',ipalloc_netmask='255.255.0.0'

      Minor tweak to "waitmode" in libreboot. · 735758ce
      Mike Hibler authored
      Previously ISUP and TBFAILED were the two states that signified that a
      node had rebooted to the satisfaction of libreboot (with waitmode==1).
      Add RELOAD/RELOADING to that list since the frisbee MFS never sends either
      of ISUP or TBFAILED.
      
      Required a modification to TBNodeStateWait() to allow waiting for an
      op-mode/state combo as well as just a state.
      
      I made this change in anticipation that it would be useful for more
      responsive monitoring of failure in tbswap/os_load. But now I am no so sure.
