      Slice expiration changes. The crux of these changes: · 5c63cf86
      Leigh 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.

      A bunch of changes for a "standalone" clearinghouse. Presently this · 60f04310
      Leigh Stoller authored
      its really a hugely stripped down Emulab boss install, using a very
      short version of install/boss-install to get a few things into place.
      
      I refactored a few things in both the protogeni code and the Emulab
      code, and whacked a bunch of makefiles and configure stuff. The result
      is that we only need to install about 10-12 files from the Emulab
      code, plus the protogeni code. Quite manageable, if you don't mind
      that it requires FreeBSD 6.X ... Still, I think it satisfies the
      requirement that we have a packaged clearinghouse that can be run
      standalone from a running Emulab site.
