      Leigh B Stoller authored
      to supply the fully specified rspec to both CMs, my changes permit you
      to specify only the component_manager_urn for the remote side.
      
      When you start the sliver, the CMs contact each other to resolve the
      slice (get the manifest), find the actual node in the manifest, and
      resolve that node to get the control network.
      
      This even allows for fully unbound rspecs to be supplied, as long as
      the component_manager_urn is specified.

      More purging of UUIDs. Reminder, we still use them all over the place · b3c8e72e
      Leigh B Stoller authored
      internally, as the primary key in the tables, but the CM/SA APIs no
      longer use them. The CH still accepts them for now. We can probably
      stop putting them into manifests and advertisements at this point as
      well. 
      
      For slivers, stop using the uuid of the node as the uuid of the sliver
      itself; generate a new one. As above, this is cause the uuid is the
      primary key in the table, but the URN is what we use for lookups,
      etc.

      Big cleanup of GeniComponent stuff. Moved Resolve() into GeniComponent · b63cb055
      Leigh B Stoller authored
      since it has to be aware of the CM version. Add a Version() call to
      GeniAuthority with goes asks the CM what version it is exporting.
      Based on that, we know how to do a resolve of a component. Refactored
      the code that was used in GeniAggregate when creating tunnels, since
      that is where we have to Resolve components. This also turns up in
      cooked mode.
      
      Continuine moving towards a urn-only world. If a GeniAuthority or a
      GeniComponent does not have the URN set locally in the DB, go back to
      the clearinghouse and get it. Error if it is not known, and go bang on
      the remote site to update and rerun register_resources.

      Slice expiration changes. The crux of these changes: · 5c63cf86
      Leigh B. Stoller authored
      1. You cannot unregister a slice at the SA before it has expired. This
         will be annoying at times, but the alphanumeric namespace for slice
         ames is probably big enough for us.
      
      2. To renew a slice, the easiest approach is to call the Renew method
         at the SA, get a new credential for the slice, and then pass that
         to renew on the CMs where you have slivers.
      
      The changes address the problem of slice expiration.  Before this
      change, when registering a slice at the Slice Authority, there was no
      way to give it an expiration time. The SA just assigns a default
      (currently one hour). Then when asking for a ticket at a CM, you can
      specify a "valid_until" field in the rspec, which becomes the sliver
      expiration time at that CM. You can later (before it expires) "renew"
      the sliver, extending the time. Both the sliver and the slice will
      expire from the CM at that time.
      
      Further complicating things is that credentials also have an
      expiration time in them so that credentials are not valid forever. A
      slice credential picks up the expiration time that the SA assigned to
      the slice (mentioned in the first paragraph).
      
      A problem is that this arrangement allows you to extend the expiration
      of a sliver past the expiration of the slice that is recorded at the
      SA. This makes it impossible to expire slice records at the SA since
      if we did, and there were outstanding slivers, you could get into a
      situation where you would have no ability to access those slivers. (an
      admin person can always kill off the sliver).
      
      Remember, the SA cannot know for sure if there are any slivers out
      there, especially if they can exist past the expiration of the slice.
      
      The solution:
      
      * Provide a Renew call at the SA to update the slice expiration time.
        Also allow for an expiration time in the Register() call.
      
        The SA will need to abide by these three rules:
        1. Never issue slice credentials which expire later than the
           corresponding slice
        2. Never allow the slice expiration time to be moved earlier
        3. Never deregister slices before they expire [*].
      
      * Change the CM to not set the expiration of a sliver past the
        expiration of the slice credential; the credential expiration is an
        upper bound on the valid_until field of the rspec. Instead, one must
        first extend the slice at the SA, get a new slice credential, and
        use that to extend the sliver at the CM.
      
      * For consistency with the SA, the CM API will changed so that
        RenewSliver() becomes RenewSlice(), and it will require the
        slice credential.

      Temp fix for the problem of tunnels not working, which was caused by · 4a64493c
      Leigh B. Stoller authored
      a missing url in the certificate for component (node). Why was that?
      Well, when I create a sliver, I use the same uuid as the node, and
      then later when I need to find the node for that sliver, I look for it
      in the nodes table using the that uuid. This was bad cause for each
      sliver I create a new certificate pair, and thus a new uuid. This
      overwrites the original certificate bound to that node, only the new
      certificate is not created with a URL. This is bad all around, but
      with uuids being replaced by URNs and so close to the demo, I am not
      going to fix this properly, but rather just avoid the problem by
      reusing the existing certificate for the node when creating a sliver.
      Revisit later this week.

      Two big changes · e6c90969
      Leigh B. Stoller authored
      1. Allow use of the shared nodes via the "exclusive" tag in the rspec.
      
      2. Switch to using the mapper in GetTicket() and in RedeemTicket() as
         per this email I sent:
      
      * GetTicket(): New rspec comes in and I build a virtual topology as I
       parse the rspec. Basically, virt_nodes and virt_lans table entries,
       which are stored into the DB. The rspec can include wildcards or
       specific nodes; I use the "fixed" slot of the virt_nodes table. Note
       that I am not yet handling fixed ifaces. Nice thing about this is
       that all of the show exp tools work.
      
       I run the (new) mapper on it in "solution" mode. This does two
       things; wildcards are mapped, and 2) it verifies that the rspec is
       mappable on the local hardware. Solution mode does not actually
       change the DB, but rather it spits out an XML file that I parse
       (note, we eventually will pass the rspec through, but I am not ready
       for that yet). I then allocate the nodes to the holding area, update
       the rspec, create a ticket, and return it.
      
      * RedeemTicket(): I run the new mapper again, only this time in real
       mode with -update. This is basically a redo of the run above since
       all the nodes are reserved already, but the DB is actually filled
       out this time. I then create the slivers and such.
      
       The other difference is that instead of creating the vlans by hand,
       I can now run snmpit -t to do the work for me. Ditto for tear down
       with snmpit -r.
      
       Another bonus is that I can add (missing) IP addressess during the
       initial rspec parse, and the nodes now boot and have their
       interfaces configured. Virtual interfaces too, including the ones
       inside of virtual nodes.
      
      * All of the above works with shared nodes too:
      
      "<rspec xmlns=\"http://protogeni.net/resources/rspec/0.1\"> " +\
      " <node virtual_id=\"geni1\" "+\
      "       virtualization_type=\"emulab-vnode\" " +\
      "       virtualization_subtype=\"emulab-openvz\" " +\
      "       exclusive=\"0\"> " +\
      "   <interface virtual_id=\"virt0\"/> " +\
      " </node>" +\
      " <node virtual_id=\"geni2\" "+\
      "       virtualization_type=\"emulab-vnode\" " +\
      "       virtualization_subtype=\"emulab-openvz\" " +\
      "       exclusive=\"0\"> " +\
      "   <interface virtual_id=\"virt0\"/> " +\
      " </node>" +\
      " <link virtual_id=\"link0\"> " +\
      "  <interface_ref " +\
      "            virtual_interface_id=\"virt0\" " +\
      "            virtual_node_id=\"geni1\" " +\
      "            /> " +\
      "  <interface_ref " +\
      "            virtual_interface_id=\"virt0\" " +\
      "            virtual_node_id=\"geni2\" " +\
      "            /> " +\
      " </link> " +\
      "</rspec>"
      
      The shared nodes boot, and you can ping on the experimental networks.
      
      Caveats:
      
      * UpdateTicket and UpdateSliver need work as per the mail I sent the
       other day about the state of the sliver between the ticket and the
       sliver operations.
      
      * Collocation specifications are ignored since we do not have any way
       to specify this to assign when wildcards are used. Rob, I am
       wondering if assign has any tricks we can take advantage of.
      
      * Still need to commit all the snmpit changes and get that hooked into
       the CM.
