      Support "no NFS mount" experiments. · 5446760e
      Mike Hibler authored
      We have had the mechanism implemented in the client for some time and
      available at the site-level or, in special cases, at the node level.
      New NS command:
      
          tb-set-nonfs 1
      
      will ensure that no nodes in the experiment attempt to mount shared
      filesystems from ops (aka, "fs"). In this case, a minimal homdir is
      created on each node with basic dotfiles and your .ssh keys. There will
      also be empty /proj, /share, etc. directories created.
      
      One additional mechanism that we have now is that we do not export filesystems
      from ops to those nodes. Previously, it was all client-side and you could
      mount the shared FSes if you wanted to. By prohibiting the export of these
      filesystems, the mechanism is more suitable for "security" experiments.

      Parser hacks for blockstores · bb2563cf
      Kirk Webb authored
      * Translate bandwidth spec "~" to 10Kbps, and complain if any other value
        is used on a lan with blockstores.
      
      * Allow blockstores to be fixed to nodes.  Shunt through cases where the
        node a blockstore is fixed to isn't a blockstore pseudo-VM via a
        features / desires hack.  We do this to avoid having a more heavyweight
        blockstore pseudo-VM representation show up when users just want more
        local disk space setup on their nodes.

      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).

      Keith Sklower's changes to support a single control network model for · 08737f67
      Leigh Stoller authored
      ElabInElab experiments, so as not to consume an interface.
      
      I actually modified Keith's changes so that we can dynmaically choose
      the single or dual model in the NS file (Keith's changes hardwired the
      system to only single control network) since the single network model
      has the disadvantage of not allowing new nodes to be added to an inner
      elab, which would make it impossible to test some things (like the
      newnode path!).
      
      To choose the single control network model, place this in your NS file:
      
      	tb-elabinelab-singlenet
      
      other it defaults to the older dual network model.

      Support for capturing the trace data that is stored in the pcal files · 4ce9c421
      Leigh Stoller authored
      into per-experiment databases on ops. Additional support for reconsituting
      those databases back into temporary databases on ops, for post processing.
      
      * This revision relies on the "snort" port (/usr/ports/security/snort)
        to read the pcap files and load them into a database. The schema is
        probably not ideal, but its better then nothing. See the file
        ops:/usr/local/share/examples/snort/create_mysql for the schema.
      
      * For simplicity, I have hooked into loghole, which already had all
        the code for downloading the trace data. I added some new methods to
        the XMLRPC server for loghole to use, to get the users DB password
        and the name of the per-experiment database. There is a new slot in
        the traces table that indicates that the trace should be snorted to
        its DB. In case you forgot, at the end of a run or when the instance
        is swapped out, loghole is run to download the trace data.
      
      * For reconsituting, there are lots of additions to opsdb_control and
        opsdb_control.proxy to create "temporary" databases and load them
        from a dump file that is stored in the archive. I've added a button
        to the Template Record page, inappropriately called "Analyze" since
        right now all it does is reconsitute the trace data into a DB on
        ops.
      
        Currently, the only indication of what has been done (the name of
        the DBs created on ops) is the log email that the user gets. A
        future project is tell the user this info in the web interface.
      
      * To turn on database capturing of trace data, do this in your NS
        file:
      
      	set link0 ...
      	$link0 trace
      	$link0 trace_snaplen 128
      	$link0 trace_db 1
      
         the increase in snaplen is optional, but a good idea if you want
         snort to undertand more then just ip headers.
      
      * Also some changes to the parser to allow plain experiments to take
        advantage of all this stuff. To simple get yourself a per-experiment
        DB, put this in your NS file:
      
      	tb-set-dpdb 1
      
        however, anytime you turn trace_db on for a link or lan, you
        automatically get a per-experiment DB.
      
      * To capture the trace data to the DB, you can run loghole by hand:
      
      	loghole sync -s
      
        the -s option turns on the "post-process" phase of loghole.

      More tightly connect the notion of a firewall and the security level. · f1206314
      Mike Hibler authored
      If you specify an explicit firewall, you are implicitly assigned security
      level 2 and you cannot explicitly specify the security level.  Likewise,
      if you specify a security level, you cannot also specify a firewall.
      
      The reason for this is that security level 1 (aka "Blue") now has a slightly
      different meaning.  It is intended for protecting the inside from the outside
      rather than visa-versa.  The only practical implication of this is that for
      level 1, we don't do all the fancy power-off-boot-into-MFS-zapbootblock stuff
      that we do for higher levels.
      
      Anyway, I wanted to make sure that if you specify your own firewall, you
      DO have to go through the full cleansing swapout since we can't trust a
      firewall that the Average Joe sets up.

      Mote and robot related stuff.  The main thing is the addition of relay

      	handler that lets the user set agent attributes (command, tag,
      	timeout) without having to run a program.
      
      	* event/sched/GNUmakefile.in, event/sched/console-agent.cc,
      	event/sched/console-agent.h, event/sched/event-sched.c: Add
      	console agents that can be used to snapshot a section of the

      	* event/sched/node-agent.cc: Some minor cleanup.
      
      	* event/sched/simulator-agent.cc, event/sched/simulator-agent.h:
      	Add the config data to the report mail.  Add a "RESET" event
      	handler that runs "loghole clean".  Save the report mail in a file
      	so it gets archived with the rest of the logs.
      
      	* lib/libtb/tbdefs.h: Add CONSOLE object type.
      
      	* mote/GNUmakefile.in, mote/newmote: Add newmote script, just a
      	quick hack to add motes to the DB.
      
      	* mote/tbuisp.in: Add another backend for loading motes through
      	their relay capture server.
      
      	* robots/mtp/mtp_dump.c: Dump the min/max values for x and y,
      	handy for figuring out the bounds of the camera.
      
      	* sql/database-fill.sql: Change the RELOAD-MOTE/SHUTDOWN ->
      	ALWAYSUP/SHUTDOWN mode transition to ALWAYSUP/ISUP since stated
      	doesn't seem to run triggers after a state change by a mode
      	transition.
      
      	* tbsetup/tbreport.in: Change the ordering of the eventlist so it

      	* tbsetup/ns2ir/sequence.tcl: Add an "append" method so it is
      	easier to build sequences dynamically.
      
      	* tbsetup/ns2ir/topography.tcl: Make checkdest available to
      	regular users.
      
      	* tip/GNUmakefile.in, tip/tiptunnel.c: Add support for uploading a
      	file to a relay version of capture and exporting the end
      	connection as a pty.
      
      	* tmcd/decls.h, tmcd/common/libsetup.pm: Bump version number since
      	the dosubnodelist change is not backwards compatible.
      
      	* tmcd/tmcd.c: Make dosubnodelist and dosubconfig callable even
      	when a node isn't allocated.  Add dotiptunnels command that
      	returns which serial consoles are to be mounted on a node.  Add
      	mote version of subconfig that returns information needed to
      	startup the relay version of capture.
      
      	* tmcd/common/bootsubnodes: For motes, startup the relay version
      	of capture (XXX stargate specific).
      
      	* tmcd/common/libsetup.pm, tmcd/common/libtmcc.pm,
      	tmcd/common/config/rc.config, tmcd/common/config/rc.tiptunnels:
      	Client side changes for mounting another nodes serial line.
      
      	* tmcd/common/rc.bootsetup: Always boot the subnodes, even when
      	free.  This is used for motes since their capture needs to be up
      	for reloading at the time.
      
      	* tmcd/linux/ixpboot: Shuffle some code around so the script
      	doesn't fail if the ixp isn't allocated.
      
      	* utils/loghole.in: Add "digest.out" and "report.mail" as global
      	logs to be saved in archives and display the "report.mail" file
      	when showing a loghole archive.
      
      	* xmlrpc/emulabserver.py.in: Scrub more of the return values to

      	virtual_tables.  Add emulab.vision_config and
      	emulab.obstacle_config methods for getting information pertaining
      	to the robots.  Change the OSID listing to include more fields.
      	Add a "physical" aspect to experiment.info to get information
      	about the physical nodes.  Add parent field to the events in the
      	array returned by eventlist.  Add sshdescription to get extra
      	information needed to log into a vnode.  Add node.statewait so you
      	can wait for nodes to come up.

      See the new advanced tutorial section on event groups for a better
      example.
      
      Changed tbreport to dump the event groups table when in summary mode.
      At the same time, I changed tbreport to use the recently added
      virt_lans:vnode and ip slots, decprecating virt_nodes:ips in one more
      place. I also changed the web interface to always dump the event and
      event group summaries.
      
      The parser gets a new file (event.tcl), and the "at" method deals with
      event group events by expanding them inline into individual events
      sent to each member. For some agents, this is unavoidable; traffic
      generators get the initial params in the event, so it is not possible
      to send a single event to all members of the group. Same goes for
      program objects, although program objects do default to the initial
      command now, at least on new images.
      
      Changed the event scheduler to load the event groups table. The
      current operation is that the scheduler expands events sent to a
      group, into a set of distinct events sent to each member of the
      group. At some point we proably want to optimize this by telling the
      agents (running on the nodes) what groups they are members of.
      
      Other News: Added a "mustdelay" slot to the virt_lans table so the
      parser can tell assign_wrapper that a link needs to be delayed, say if
      there are events or if the link is red/gred. Previously,
      assign_wrapper tried to figure this out by looking at the event list,
      etc. I have removed that code; see database-migrate for instructions
      on how to initialize this slot in existing experiments. assign_wrapper
      is free to ignore or insert delays anyway, but having the parser do
      this makes more sense.
      
      I also made some "rename" changes to the parser wrt queues and lans
      and links. Not really necessary, but I got sidetracked (for several
      hours!) trying to understand that rename stuff a little better, and
      now I do.
