      Okay, I think I am finally done with WikiWhacking (or WhackingTheWiki?) · 90dcbbe2
      Leigh B. Stoller authored
      for the near future. Two big changes:
      
      * Add WikiOnly accounts. An external user can register for an account on
        the wiki. Rather then use the registration stuff that comes with TWiki,
        redirect to new Emulab web page so we can manage all of the wiki accounts
        from one place. I modified the joinproject page to spit out a subset of
        the required fields so that its simple to get a wiki only account (just a
        few things to fill in).
      
        In keeping with current security practices, we still generate a
        verification email message to ensure the email address works. However,
        when the user completes the verification, the wiki account is created right
        away, rather then waiting for someone to approve it (since that would
        defeat the entire point of the wiki).
      
        Aside: I have not thought much about the conversion from a wiki-only
        account to a real account. That is going to happen, and it would be nice
        if that step did not require one of use to go in and hack the DB. Will
        cross that moat later.
      
        Aside: Rather beat up on the modify user info page too much, I continue
        to spit out the same form, but mark most of the fields as not required,
        and allow wiki-only people to not specify them.
      
      * Both the joinproject and newproject pages sport a new WikiName field so
        that users can select their own WikiName. I added some JavaScript to
        both pages that generate a suitable wikiname from the FullName field, so
        that as soon as the user clicks out of the FullName, a default wikiname is
        inserted in the field.
      
        Both pages verify the wikinames by checking to make sure it is not
        already in use, and that it meets the WikiRules for WikiTopic names.
        (someone please shoot me if I continue to use WikiNotation).

      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.

      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).

      First try at solving the problem of validating user input for the · 8dbead16
      Leigh B. Stoller authored
      zillions of DB fields that we have to set. My solution was to add a
      meta table that describes what is a legal value for each table/slot
      for which we take from user input. The table looks like this right
      now, but is likely to adapt as we get more experience with this
      approach (or it might get tossed if it turns out to be a pain in the
      ass!).
      
      	CREATE TABLE table_regex (
      	  table_name varchar(64) NOT NULL default '',
      	  column_name varchar(64) NOT NULL default '',
      	  column_type enum('text','int','float') default NULL,
      	  check_type enum('regex','function','redirect') default NULL,
      	  check tinytext NOT NULL,
      	  min int(11) NOT NULL default '0',
      	  max int(11) NOT NULL default '0',
      	  comment tinytext,
      	  UNIQUE KEY table_name (table_name,column_name)
      	) TYPE=MyISAM;
      
      Entries in this table look like this:
      
      	('virt_nodes','vname','text','regex','^[-\\w]+$',1,32,NULL);
      
      Which says that the vname slot of the virt_nodes table (which we trust the
      user to give us in some form) is a text field to be checked with the given
      regex (perlre of course), and that the min/max length of the text field is
      1 and 32 chars respectively.
      
      Now, you wouldn't want to write the same regex over and over, and since we
      use the same fields in many tables (like pid, eid, vname, etc) there is an
      option to redirect to another entry (recursively). So, for "PID" I do this:
      
              ('eventlist','pid','text','redirect','projects:pid',0,0,NULL);
      
      which redirects to:
      
      	('projects','pid','text','regex','^[a-zA-Z][-\\w]+$',2,12,NULL);
      
      And, for many fields you just want to describe generically what could go
      into it. For that I have defined some default fields. For example, a user
      description:
      
              ('experiment,'usr_name','text','redirect','default:tinytext',0,0,NULL);
      
      which redirects to:
      
      	('default','tinytext','text','regex','^[\\040-\\176]*$',0,256,NULL);
      
      and this says that a tinytext (in our little corner of the database
      universe) field can have printable characters (but not a newline), and
      since its a tinytext field, its maxlen is 256 chars.
      
      You also have integer fields, but these are little more irksome in the
      details.
      
      	('default','tinyint,'int,'regex','^[\\d]+$',-128,127,NULL);
      
      and you would use this anyplace you do not care about the min/max values
      being something specific in the tinyint range. The range for a float is of
      course stated as an integer, and thats kinda bogus, but we do not have many
      floats, and they generally do not take on specific values anyway.
      
      A note about the min/max fields and redirecting. If the initial entry has
      non-zero min/max fields, those are the min mac fields used. Otherwise they
      come from the default. So for example, you can do this:
      
          ('experiments','mem_usage','int','redirect','default:tinyint',0,5,NULL);
      
      So, you can redirect to the standard "tinyint" regular expression, but you
      still get to define min/max for the specific field.
      
      Isn't this is really neat and really obtuse too? Sure, you can say it.
      
      Anyway, xmlconvert now sends all of its input through these checks (its
      all wrapped up in library calls), and if a slot does not have an entry, it
      throws an error so that we are forced to define entries for new slots as we
      add them.
      
      In the web page, I have changed all of the public pages (login, join
      project, new project, and a couple of others) to also use these checks.
      As with the perl code, its all wrapped up in a library. Lots more code
      needs to be changed of course, but this is a start.

      Merge the two state machines (batchstate and state) into a single · 2025e0bd
      Leigh B. Stoller authored
      state machine (state). All of the stuff that was previously handled by
      using batchstate is now embedded into the one state machine. Of
      course, these mostly overlapped, so its not that much of a change,
      except that we also redid the machine, adding more states (for
      example, modify phases are now explicit. To get a picture of the
      actual state machine, on boss:
      
      		stategraph -o newstates EXPTSTATE
      		gv newstates.ps
      
      Things to note:
      
      * The "batchstate" slot of the experiments table is now used solely to
        provide a lock for batch daemon. A secondary change will be to
        change the slot name to something more appropriate, but it can
        happen anytime after this new stuff is installed.
      
      * I have left expt_locked for now, but another later change will be to remove
        expt_locked, and change it to active_busy or some such new state name in
        the state machine. I have removed most uses of expt_locked, except those
        that were necessary until there is a new state to replace it.
      
      * These new changes are an implementation of the new state machine,
        but I have not done anything fancy. Most of the code is the same as
        it was before.
      
      * I suspect that there are races with the batch daemon now, but they
        are going to be rare, and the end result is probably that a
        cancelation is delayed a little bit.

      * Add TBvalid_uid() function to regex uid's. To be used throughout the
        system. Eventually add routines for checking other things like pids
        and eids, etc.
      
      * Regex the uid value we get from the cookie, and switch to $_COOKIE
        superglobal.
      
      * Strict regex checking in DOLOGIN() of uid.
      
      * Change login.php to use superglobals, and general tightening of
        parameter checking.

      Reorg of two aspects of node update. · 2641af4d
      Leigh B. Stoller authored
      * install-rpm, install-tarfile, spewrpmtar.php3, spewrpmtar.in: Pumped
        up even more! The db file we store in /var/db now records both the
        timestamp (of the file, or if remote the install time) and the MD5
        of the file that was installed. Locally, we can get this info when
        accessing the file via NFS (copymode on or off). Remote, we use wget
        to get the file, and so pass the timestamp along in the URL request,
        and let spewrpmtar.in determine if the file has changed. If the
        timestamp it gets is >= to the timestamp of the file, an error code
        of 304 (Not Modifed) is returned. Otherwise the file is returned.
      
        If the timestamps are different (remote, server sends back an actual
        file), the MD5 of the file is compared against the value stored. If
        they are equal, update the timestamp in the db file to avoid
        repeated MD5s (or server downloads) in the future. If the MD5 is
        different, then reinstall the tarball or rpm, and update the db file
        with the new timestamp and MD5. Presto, we have auto update capability!
      
        Caveat: I pass along the old MD5 in the URL, but it is currently
        ignored. I do not know if doing the MD5 on the server is a good
        idea, but obviously it is easy to add later. At the moment it
        happens on the node, which means wasted bandwidth when the timestamp
        has changed, but the file has not (probably not something that will
        happen in typical usage).
      
        Caveat: The timestamp used on remote nodes is the time the tarfile
        is installed (GM time of course). We could arrange to return the
        timestamp of the local file back to the node, but that would mean
        complicating the protocol (or using an http header) and I was not in
        the mood for that. In typical usage, I do not think that people will
        be changing tarfiles and rpms so rapidly that this will make a
        difference, but if it does, we can change it.
      
      * node_update.in, client side watchdog, and various web pages:
        Deflated node_update, removing all of the older ssh code. We now
        assume that all nodes will auto update on a periodic basis, via the
        watchdog that runs on all client nodes, including plab nodes.
      
        Changed the permission check to look for new UPDATE permission (used
        to be UPDATEACCOUNT). As before, it requires local_root or better.
        The reason for this is that node_update now implies more than just
        updating the accounts/mounts. The web pages have been changed to
        explain that in addition to mounts/accounts, rpms and tarfiles will
        also be updated. At the moment, this is still tied to a single
        variable (update_accounts) in the nodes table, but as Kirk requested
        at the meeting, it will probably be nice to split these out in the
        future.
      
        Added the ability to node_update a single node in an experiment (in
        addition to all nodes option on the showexp page). This has been
        added to the shownode webpage menu options.
      
        Changed locking code to use the newer wrapper states, and to move
        the experiment to RUNNING_LOCKED until the update completes. This is
        to prevent mayhem in the rest of the system (which could be dealt
        with, but is not worth the trouble; people have to wait until their
        initiated update is complete, before they can swap out the
        experiment).
      
        Added "short" mode to shownode routine, equiv to the recently added
        short mode for showexp. I use this on the confirmation page for
        updating a single node, giving the user a couple of pertinent (feel
        good) facts before they comfirm.

      Up to now we have had two state variables associated with an experiment, · 4269dad1
      Leigh B. Stoller authored
      plus a lock field. The lock field was a simple "experiment locked, go away"
      slot that is easy to use when you do not care about the actual state that
      an experiment is in, just that it is in "transition" and should not be
      messed with.
      
      The other two state variables are "state" and "batchstate". The former
      (state) is the original variable that Chris added, and was used by the tb*
      scripts to make sure that the experiment was in the state each particular
      script wanted them to be in. But over time (and with the addition of so
      much wrapper goo around them), "state" has leaked out all over the place to
      determine what operations on an experiment are allowed, and if/when it
      should be displayed in various web pages. There are a set of transition
      states in addition to the usual "active", "swapped", etc like "swapping"
      that make testing state a pain in the butt.
      
      I added the other state variable ("batchstate") when I did the batch
      system, obviously! It was intended as a wrapper state to control access to
      the batch queue, and to prevent batch experiments from being messed with
      except when it was really okay (for example, its okay to terminate a
      swapped out batch experiment, but not a swapped in batch experiment since
      that would confuse the batch daemon). There are fewer of these states, plus
      one additional state for "modifying" experiments.
      
      So what I have done is change the system to use "batchstate" for all
      experiments to control entry into the swap system, from the web interface,
      from the command line, and from the batch daemon. The other state variable
      still exists, and will be brutally pushed back under the surface until its
      just a vague memory, used only by the original tb* scripts. This will
      happen over time, and the "batchstate" variable will be renamed once I am
      convinced that this was the right thing to do and that my changes actually
      work as intended.
      
      Only people who have bothered to read this far will know that I also added
      the ability to cancel experiment swapin in progress. For that I am using
      the "canceled" flag (ah, this one was named properly from the start!), and
      I test that at various times in assign_wrapper and tbswap. A minor downside
      right now is that a canceled swapin looks too much like a failed swapin,
      and so tbops gets email about it. I'll fix that at some point (sometime
      after the boss complains).
      
      I also cleaned up various bits of code, replacing direct calls to exec
      with calls to the recently improved SUEXEC interface. This removes
      some cruft from each script that calls an external script.
      
      Cleaned up modifyexp.ph3 quite a bit, reformatting and indenting.
      Also fixed to not run the parser directly! This was very wrong; should
      call nscheck instead. Changed to use "nobody" group instead of group
      flux (made the same change in nscheck).
      
      There is a script in the sql directory called newstates.pl. It needs
      to be run to initialize the batchstate slot of the experiments table
      for all existing experiments.

      Convert install-rpm/install-tarfile to use the web server instead of · 0a259517
      Leigh B. Stoller authored
      tmcd (which is bad, since tying up the tmcd threads blocks all nodes
      in the testbed). The old functionality is left in tmcd for now.
      
      On the server side, a new web page (www/spewrpmtar.php3) receives a
      request for a file, along with the nodeid (pcXXX) making the request,
      and the secret key that is generated for each new experiment and
      transfered to the node via tmcd. If the key matches, the operation is
      handed off to tbsetup/spewrpmtar.in which verifies that the file is in
      the list of rpm/tar files for that node, and then spits it out to
      stdout. The web page uses fpassthru() to send the file out to the
      client. The client is using wget, and is required to use https (the
      web page checks).
      
      At present, the external script is run as the creator of the
      experiment, and gid of the experiment. Perhaps this is not a good
      idea. In any event, the file must be in the list of rpm/tarfiles,
      either owned by the experiment creator or with a group of the
      experiment, and the file must reside in either /proj or /groups.
      I use the realpath() function to make sure there are no symlink tricks
      pointing to outside those filesystems. I use the standard NFS read goo to
      prevent transient mount problems that we all know and love.

      to look at the page in both admin mode and non-admin mode since I had

      Oh, added the ability to convert non-batch experiments into batch, and
      back. The experiment must be unlocked and in the swapped state to go
      in either direction.
      
      Also added the cpu_usage and mem_usage slots for editing. I added a
      comment about planetlab only, since otherwise we would just confuse
      normal users who have no idea what they mean. I could conditionalize
      them on having plab nodes, but thats difficult to figure out in the
      web page when the experiment is swapped out, so lets not worry about
      it.

      bug I found while trying to figure out the batchmode problem reported
      this morning by the FileMover people, is that the cancelflag is not
      cleared after swaping a running batch experiment out, so even after
      reinjecting it into the queue, it will not run. Still, that does seem
      to be what the FileMover people reported.

      Added site variables ('sitevars').
      These are stored in the sitevariables database table.
      Each one has a name, a description (NOT OPTIONAL!), a
      default value, and a current value.
      If the current value is NULL, the default value is used.
      
      Soon, a mechanism will be added to the install process to
      ensure all needed site variables exist before installing;
      more on that when it is committed.
      
       - Added 'editsitevars.php3' page, accessable to admins
         via the 'Edit Site Variables' menu option.
      
       - Added 'setsitevar' script,
         an interface for listing, viewing in detail, and setting
         site variables.
      
       - Web interface now uses 'web/nologins' and 'web/message'
         instead of one-off database tables.
      
      NOTE that setting a variable to the default value and
      setting a variable to a value which is string-identical
      are NOT the same thing.
      (This doesn't matter yet, but when we push default values out to
       remote sites as part of our install, it will.)
