      Another little hack for Mike; Add a "lockdown" bit to the experiments · d8b17f2c

      table that will prevent an experiment from being swapped/modified. The
      toggle is on the showexp page, and the toggle is *not* admin
      over-ridable; you must turn the toggle off (and of course, you must be
      an admin to do that).

      A quick hack job to get the webcams onto the web interface. · d46902e1
      Leigh B. Stoller authored
      * Add new DB table "webcams" which hold the id of the webcam, the
        server it is attached to, and the last update time.
      
      * Add new sitevars webcam/anyone_can_view and webcam/admins_can_view.
        Should be obvious what they mean.
      
      * Add trivial script grabwebcams (invoked from cron) to grab the images
        from the servers and stash in /usr/testbed/webcams. The images are
        grabbed with scp, protected by a 5 second timeout. Fine for a couple
        of cameras.
      
      * Add web page stuff to display webcams, linked from the robot mape page.
      
      Permission to view the webcams is currently admin, or in a project that is
      allowed to use a robot. We can tighten this up later as needed.

      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.

      Rework old XMLRPC code that I stuck into defs.php3 a long time ago, · 98d2ab5f
      Leigh B. Stoller authored
      but never made use of. Moved to its own file (www/xmlrpc.php3.in)
      and made to be more like the perl library I did a couple of months ago,
      that presents an interface to an sslxmlrpc server, via the sslxmlrpc
      client program operating in "raw" mode (takes raw xml on stdin, and
      returns raw xml on stdout).
      
      Added ELABINELAB code to nodetipacl.php3 so that you can click on
      console icon on an inner emulab web page, and it will ask the outer
      emulab sslxmlrpc server for the stuff it needs, and return that to the
      user.

      You can specify any display resolution you want; it doesn't have to be
      one of the "normal" ones.  And you can switch back and forth by just starting
      a new rdesktop and "grabbing" the rlogin session away from the previous one.
      
      But once an rdesktop is started up, its display resolution is fixed.  If you make it
      smaller than the previous one, it will push your windows around to fit.

      The panic button ... · 87dd2e60
      Leigh B. Stoller authored
      * tbsetup/panic.in: New backend script to implement the panic button
        feature. When used, it will cut the severe the connection to the
        firewall node by using snmpit to disable the port. Sets the panic
        bit (and date) in the experiments table, and changes the state of
        the experiment from "active" to "paniced" to ensure that the
        experiment cannot be messed with (swapped out or modified). Sends
        email to tbops when the panic button is pressed.
      
        Used with -r option, reverses the above. State is set back to
        active, the panic bit is cleared, and the port is renabled with
        snmpit.
      
      * tbsetup/tbswap.in: During swapout, a firewalled experiment that has
        been paniced will get a cleaning; The nodes are powered off, then
        the osids for all the nodes are reset (with os_select) so that they
        will boot the MFS, and then the nodes are powered on. Then the
        control network is turned back on, and then I wait for the nodes to
        reboot (this is simply cause we do not record in the DB that a node
        is turned off, and if I do not wait, the reload daemon will end
        hitting the power button again if they do not reboot in time. We can
        fix this later.
      
        I am not planning to apply this to general firewalled experiments
        yet as the power cycling is going to be hard on the nodes, so would
        rather that we at least have a 1/2 baked plan before we do that.
      
      * www/showexp.php3: If experiment is firewalled, show the Panic
        Button, linked to the panic button web script. If the experiment has
        already had the panic button pressed, show a big warning message and
        explain that user must talk to tbops to swap the experiment out.
        Also fiddle with menu options so that the terminate link is gone,
        and the swap link is visible only in admin mode. In other words, only
        an admin person can swap an experiment once it is paniced. And of
        course, an admin person can the backend panic script above with the
        -r option, but thats not something to be done lightly.
      
      * db/libdb.pm.in: Add "paniced" as an experiment state (EXPTSTATE_PANICED).
        Add utility functions: TBExptSetPanicBit(), TBExptGetPanicBit(), and
        TBExptClearPanicBit().
      
      * tbsetup/swapexp.in: Minor state fiddling so that an experiment can
        be swapped while in paniced state, but only when in admin mode. Also
        clear the panic bit when experiment is swapped out.
      
      * www/dbdefs.php3.in: Add "paniced" as an experiment state. Add a
        utility function TBExptFirewall() to see if experiment is firewalled.
      
      * www/panicbutton.php3: New web script to invoke the backend panic
        script mentioned above, after the usual confirm song and dance.
      
      * www/panicbutton.gif: New gif of a red panic button that I stole off
        the net. If anyone has sees/has a better one, feel free to replace
        this one.
      
      * utils/node_statewait.in: Add -s option so that I can pass in the
        state I want to wait for (used from tbswap above to wait for nodes
        to reach ISUP after power on).
