      Directory based image paths. · 3a21f39e
      Leigh Stoller authored
      Soon, we will have images with both full images and deltas, for the same
      image version. To make this possible, the image path will now be a
      directory instead of a file, and all of the versions (ndz,sig,sha1,delta)
      files will reside in the directory.
      
      A new config variable IMAGEDIRECTORIES turns this on, there is also a check
      for the ImageDiretories feature. This is applied only when a brand new
      image is created; a clone version of the image inherits the path it started
      with. Yes, you can have a mix of directory based and file based image
      descriptors.
      
      When it is time to convert all images over, there is a script called
      imagetodir that will go through all image descriptors, create the
      directory, move/rename all the files, and update the descriptors.
      Ultimately, we will not support file based image paths.
      
      I also added versioning to the image metadata descriptors so that going
      forward, old clients can handle a descriptor from a new server.

      Ubuntu 15 support. · 2baf7655
      David Johnson authored
      Similar to Ubuntu 14, but new and different UIDs, and...
      
      systemd!  systemd has made it into Ubuntu.  This affects our control net
      discovery.  Our /etc/network/interfaces hack marks eth[0-9] as "auto".
      New Ubuntu versions have systemd (or upstart, if your Ubuntu 15 uses
      that -- our images will not) job that waits for any interfaces marked
      auto to come up, and doesn't timeout for 2 mins.  This doesn't work for
      us, because our use of auto is abuse :).
      
      So, we enter a new level of abuse.  We change the systemd unit
      dependencies, making the network-online.target service want (depend on)
      our special ifup-wait-emulab-cnet.service (which looks for /run/cnet to
      get written), instead of on ifup-wait-all-auto.service.  This means
      network-online.target happens as soon as the control net is up, which is
      the primary thing we're concerned about.
      
      Now, if experimenters would ever add their own special "auto" interfaces
      to /etc/network/interfaces, the rest of the startup scripts that depend
      on network-online.target could possibly race (although you would think
      that our control net discovery will be slower than any static
      configuration...).
      
      But for now, this solution appealed more that "faking" that eth[0-9] are
      all up by writing the right files --- or by finding a better mechanism
      instead of abusing "auto".

      FreeBSD 11 (aka current) support. · 460cc8bf
      Mike Hibler authored
      Mostly I just wanted to test "the latest" FBSD kernel on Apt
      so see if anything done recently would help with the hanging
      console problem on the R320s (newer kernels actually only hang
      for about 10 seconds and drop around 500 chars when they probe
      the ethernet interfaces--this is better than it was).
      
      While in there, I just went ahead and did the client side,
      mostly ifdefs in the makefiles.

      Initial support for ARM-64 clientside. · db6f3b96
      Mike Hibler authored
      Clientside builds on HP Moonshot, haven't tried running anything.
      
      The most significant change here is moving to autoconf 2.69, which
      is the first that supports "aarch64". This required replacing the
      scripts in autoconf/ and significant textual changes to configure.in
      files.
      
      Other than that, it was all lint.

      Add GPO ops-monitoring support. · e9a21edc
      Gary Wong authored
      The pieces are:
      
       * A monitoring daemon (clientside/protogeni/shared-node-monitor), which
         runs in each Xen shared node dom0, and gathers node and interface
         statistics.  It communicates these over the event system with...
      
       * A listening daemon (event/monitoring/shared-node-listener), running
         on the local boss node, and inserts everything it hears into the
         MySQL database "monitoring".  This database is also used by...
      
       * A site-wide monitoring daemon (protogeni/scripts/mondbd), periodically
         polling the normal testbed database (nodes and interfaces tables) and
         copying snapshots of the important pieces into the monitoring database.
      
       * The monitoring database is also read by a WWW front end invoked as a
         WSGI process by Apache.  This front end is developed by the GPO and
         modified to work with ProtoGENI, and is maintained in an independent
         repository.

      Add IPV6 changes, contributed by Brecht and lightly modified by me. · 7de150c4
      Leigh Stoller authored
      To define, in the defs file:
      
      	IPV6_ENABLED=1
      	IPV6_SUBNET_PREFIX="2011:1948:0417:0004"
      
      A /64 network is always assumed, don't do anything else. We generate
      appropriate foward and reverse entries in the zone files, but
      otherwise rely on the on the upstream router to provide the prefix
      when asked for it by nodes when they wish to configure an IPV6
      interface.
      
      Important caveats:
      
      1. The infrastructure is ipv4 only. We do not dupport dual stack or
         ipv6 only on any infrastructure.
      
      2. We do not support ipv6 only on the control plane; ipv4 or dual stack.
