      A big set of changes to how we create XEN guest disks. · fbc26aea
      Leigh B Stoller authored
      Prior to this commit, XEN guests disks were single partition, no MBR,
      the bits dumped into the lvm. This makes a snapshot of a XEN node,
      look completely different then a physical disk image, especially if
      users want more disk space (mkextrafs) inside the guest, and then want
      to take a snapshot of that, and then run it on a physical node (which
      was not possible).
      
      With these changes, guests now use the same MBR layout as our version
      two MBR, which makes them interchangeable with physical disk images.
      In fact, the goal is to be able to switch back and forth as needed,
      based on physical resource availability.

      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      This commit is intended to makes the license status of Emulab and
      ProtoGENI source files more clear.  It replaces license symbols like
      "EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
      blocks that contain actual license statements.
      
      This change was driven by the fact that today, most people acquire and
      track Emulab and ProtoGENI sources via git.
      
      Before the Emulab source code was kept in git, the Flux Research Group
      at the University of Utah would roll distributions by making tar
      files.  As part of that process, the Flux Group would replace the
      license symbols in the source files with actual license statements.
      
      When the Flux Group moved to git, people outside of the group started
      to see the source files with the "unexpanded" symbols.  This meant
      that people acquired source files without actual license statements in
      them.  All the relevant files had Utah *copyright* statements in them,
      but without the expanded *license* statements, the licensing status of
      the source files was unclear.
      
      This commit is intended to clear up that confusion.
      
      Most Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the Affero GNU General Public License, version 3
      (AGPLv3).
      
      Most Utah-copyrighted files related to ProtoGENI are distributed under
      the terms of the GENI Public License, which is a BSD-like open-source
      license.
      
      Some Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the GNU Lesser General Public License, version 2.1
      (LGPL).

      More bits and pieces for exporting images from one Emulab to another. · 4c444cd5
      Leigh B Stoller authored
      image_metadata.php will return an Emulab style image descriptor in XML
      format. A remote emulab, given an image URL, will grab this XML
      description and use it to create a local descriptor. Inside the
      descriptor is an additional URL that is used to download ndz file.
      
      The dumpdescriptor script is now web accessible, and takes a new -e
      (export) option that adds the extra URL and other bits that are needed
      to import the descriptor and the image.
      
      On the Show Image page, show the metadata URL, which is suitable for
      using in an NS file or an rspec (when that code is committed).

      Add support for creating snapshot images of OpenVZ containers via the · fdd08bb4
      Leigh B Stoller authored
      web interface.
      
      Most of this commit is about making it easier to create the
      descriptors (of any kind) The newimageid_ez page now takes an optional
      node_id on which to base the new descriptor; most of the fields are
      initialized.
      
      You can also provide optional imageid and osinfo arguments, which
      allows for slightly less info to be initialized.
      
      Then on the ShowNode page, the link to create an image will take you
      to the snapshot image page if the user has write access to the image,
      otherwise to the newimageid_iz page to create and snapshot a new
      image descriptor.

      Add support for sharing images between projects. New table called · 646b64f6
      Leigh B Stoller authored
      image_permissions stores access info for images. You can share an
      image with a user or a group (project), and you can specify write
      access to allow updating the image in place. Note that write access
      does not allow the descriptor to be modified, only the image itself.
      Well, that is how it will be after Mike changes mfrisbeed.
      
      The front end script to modify permissions is grantimage:
      
      	boss> grantimage -u stoller -w tbres,myimage
      	boss> grantimage -u stoller -w tbres,myimage
      
      which grants write access to stoller. Or:
      
      	boss> grantimage -g testbed,testbed tbres,myimage
      
      which grants access to the testbed project. Notice that you can
      specify subgroups this way.
      
      	boss> grantimage -l tbres,myimage
      
      will give you a list of current permissions. To revoke, just add -r
      option:
      
      	boss> grantimage -g testbed,testbed -r tbres,myimage
      
      Who is allowed to grant access to an image? 1) An adminstrator of
      course, 2) the image creator, and 3) any group_root in the group that
      the image belongs to. Being granted access to use an image does not
      confer permission to grant access to others.
      
      One last task; while the web interface displays the permissions, there
      is no web interface to modify the permissions; users will still have
      to ask us for now.

      Rework the newosid web page as an example of how I want all of our current · 77540494
      Leigh B. Stoller authored
      form processing to be done.
      
      The gist is that I have moved all of the data checking and DB work to
      the backend into a new script called utils/newosid. This script does
      all the field checking that used to be done in php. It takes a simple
      XML file as input and returns a set of strings to format as errors (if
      there are any).
      
      The overall goal to make a big push to move this code out of PHP and
      perl.  A nice side effect is that many operations that are current
      only available via the web interface will also become available
      command line (and also XMLRPC with a little moew work).

      * Replace the argument processing code in all pages. Currently we rely on · 48acc8e3
      Leigh B. Stoller authored
        register_globals=1 to turn POST/GET/COOKIES arguments in local variables.
        This is known to be a terrible security risk, and we keep saying we are
        going to fix it, and now I am. In order to accomplish this on a
        transitional basis (since I don't want the entire web interface to stop
        working while I debug it), and because the code just needs the cleanup, I
        am doing it like this: Each page will sport new declarations at the top:
      
      	RequiredPageArguments("experiment", PAGEARG_EXPERIMENT,
                                    "template",   PAGEARG_TEMPLATE,
                                    "instance",   PAGEARG_INSTANCE,
                                    "metadata",   PAGEARG_METADATA,
                                    "osinfo",     PAGEARG_OSINFO,
                                    "image",      PAGEARG_IMAGE,
                                    "project",    PAGEARG_PROJECT,
                                    "group",      PAGEARG_GROUP,
                                    "user",       PAGEARG_USER,
      			      "node",       PAGEARG_NODE,
      			      "yesno",      PAGEARG_BOOLEAN,
      			      "message",    PAGEARG_STRING,
      			      "age",        PAGEARG_INTEGER,
                                    "cost",       PAGEARG_NUMERIC,
                                    "formfields", PAGEARG_ARRAY,
                                    "unknown",    PAGEARG_ANYTHING);
      
      	OptionalPageArguments("canceled", PAGEARG_BOOLEAN);
      
        The first token in each pair is the name of the global variable to
        set, and the second token is the type. So, for "experiment" we look at
        the URL for a pid/eid or exptidx, etc, sanity check them (safe for a
        DB query), and then try to find that experiment in the DB. If it maps
        to an experiment, set global variable $experiment to the object. Since
        its a required argument, produce an error if not supplied. Similar
        treatment for optional arguments, with the obvious difference.
      
        The goal is to have ALL argument processing in one place, consistent,
        and correct. I've found numerous places where we leak unchecked
        arguments into queries. It also cuts out a lot of duplicated code.
      
      * To make the above easier to deal with, I've been replacing lots of
        hardcoded URLS in the code of the form:
      
      	foo.php3?pid=$pid&eid=$eid ...
      
        with
      
              CreateURL("foo", $experiment)
      
        which creates and returns the neccessary url string, by looking at
        the type of its arguments (experiment, template, instance, etc.)
      
        Eventually plan to replace them all so that URL handling throughout
        the code is all defined in one place (all the new URL code is in
        url_defs.php).
      
      * I have cranked up error reporting to tell me anytime a variable is
        used before it is initialized, plus a bunch of other stuff that PHP
        deems improper. Think of it like -Wall ... and boy we get a lot of
        warnings.  A very large percentage of the diffs are to fix all these
        warnings.
      
        The warnings are currently going to /usr/testbed/log/php-errors.log,
        and I'll be adding a script to capture them each night and mail them
        to tbops. This file also gets errors (this will be a change for
        developers; rather then seeing errors and warnings dumped in the
        middle of web pages, they will go to this file instead).
      
      * Major refactoring of the code. More objects (nodes, images, osids).
        Moving tons of queries into the objects in the hopes of someday
        getting to a point where we can split the web interface onto a
        different server.  Lots of general cleanup.
