      Named setup gets a serious collagen injection ... As per Mike/Rob · cff2421e
      Leigh B. Stoller authored
      request, beef up named setup so that sites like DETER are handled
      properly. I have added 4 new defs variables:
      
          #
          # If your boss/ops nodes are multihomed (and typically, one of the
          # networks is a public routable network, and the other is an internal
          # unroutable network), then define the the external addresses here (and
          # the internal addresses above).
          #
          EXTERNAL_BOSSNODE_IP=$BOSSNODE_IP
          EXTERNAL_USERNODE_IP=$USERNODE_IP
      
          #
          # As above, if you have internal and external networks, define the
          # external network here, and the internal network above.
          #
          EXTERNAL_TESTBED_NETWORK=$TESTBED_NETWORK
          EXTERNAL_TESTBED_NETMASK=$TESTBED_NETMASK
      
      which if not set default to the internal values. When the external and
      internal networks are different, generate two sets of reverse zone
      files and two forward files (one internal and one external).

      A bunch of boot changes. Read carefully. · 94ccc3f4
      Leigh B. Stoller authored
      * Add boot_errno to the nodes table so that nodes can report in a
        subcode to indicate what went wrong. At present, we do not report any
        real error codes; that is going to take some time to work out since it
        will reqiure a bunch of changes to the boot scripts.
      
      * Add new table node_bootlogs to store logs provided by the nodes. Not
        a full console log, but a log of the tmcd client side part. We can
        make it a full log if we want though; just means mucking about with
        the boot phase a bit.
      
      * Add new state transition to NORMALv2 and PCVM state machines. "TBFAILED"
        is a new state that is sent (after TBSETUP) if a node fails somewhere in
        the tmcd client side.
      
      * Change TBNodeStateWait() to take a list of states (instead of single
        state) and an optional pass by reference parameter to return the actual
        state that the node landed in. Change all calls to TBNodeStateWait() of
        course.
      
      * Change os_setup (and libreboot in wait mode) to look for both TBFAILED
        and ISUP. If a TBFAILED event is seen, we can terminate the wait early
        and not retry os_setup on physical nodes (although still retry virtual
        nodes). The nice thing about this is that the wait should terminate much
        earlier (rather then waiting for timeout), especially for virtual nodes
        which can take a really long time when there are a couple of hundred.
      
      * Add new routines dobooterrno() and dobootlog() to tmcd. Bump version
        number and increase the buffer size to allow for the larger packets that
        a console log wikk generate (added MAXTMCDPACKET variable, set to 0x4000).
      
      * Add new -f option to tmcc to specify a datafile to send along as the last
        argument to tmcd. This is more pleasing then trying to send a console log
        in on the command line. For example: "tmcc -f /tmp/log BOOTLOG" will send
        a BOOTLOG command along with the contents of /tmp/log.
      
        Also close the write side of the pipe so that server sees EOF on
        read. See aside comment below.
      
      * Changes to rc.bootsetup:
           1. Use perl tricks to capture all output, duping to the console and to
              a log file in /var/emulab/logs.
           2. On any error, send a status code (boot_errno) and the bootlog to
              tmcd.
           3. Generate a TBFAILED state transition.
      
      * Changes to rc.injail:
           1. Same as rc.bootsetup, but do not send log files; that would pummel
              boss. Leave them on the physical node.
      
      * Change vnodesetup (which calls mkjail) to watch for any error and send a
        TBFAILED state transition. This should catch almost all errors, and
        dramatically reduce waiting when something fails.
      
      * Changes to rc.cdboot are essentially the same as rc.bootsetup, although a
        bootlog is sent all the time (success or failure), and I do not generate
        a boot_errno yet. Also, instead of TBFAILED, generate a PXEFAILED state
        since the CDROM is actually operating within the PXEFBSD opmode. I have
        yet to work this into the rest of the system though; waiting to get a new
        CD built and actually experiment with it.
      
      * Add new menu option and web page to display the node bootlog. We store
        only the lastest bootlog, but maybe someday store more then one. Display
        boot_errno on node page.
      
      Aside: I made a big mistake in the tmcd protocol; I did not envision
      passing more then a small amount of data (one fragment) and so I do not
      include a record terminator (ie: close of the write side on the client
      sends EOF) or a size field at the beginning. No big deal since small
      requests are sent in one fragment and the server sees the entire
      thing. Well, with a large console log, that will end up as multiple
      fragments, and the server will often not get the entire thing on the first
      read, and there are no subsequent reads (with no EOF or known size, it
      would block forever). Well, fixing this in a backwards compatable manner
      (for old images) was way too much pain. Instead, tmcc now closes the write
      side, and the server does subsequent reads *only* in the new dobbootlog()
      routine. Note that it *is* possible to fix this in a backwards compatable
      manner, but I did not want to go down that path just yet.
