      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).

      Add -w option to os_select to put a node in PXEWAIT. · 4a4dcaa2
      Mike Hibler authored
      Replaces a direct DB query in the elabinelab code to perform the same function.
      Also, make sure that os_select allows a symbolic osid in a form that the
      OSinfo->Lookup() method actually accepts (pid/osname rather than osname).

      Death to proxydhcp; one less specialized daemon. DHCP will return the · 2b2b8ca1

      filename to boot, and all local nodes will boot the same pxeboot kernel,
      which has been extended to allow for jumping directly into a specific MFS
      (in addition to the usual testbed boot into a partition or multiboot
      kernel).
      
      Bootinfo and the bootwhat protocol extended to tell the client node what
      MFS to jump into directly, without a reboot. pxe_boot_path and
      next_pxe_boot_path are now deprecated, with bootinfo used to control which
      MFS to boot. Nodes now boot a single pxeboot kernel, and bootinfo tells
      them what to do next.
      
      Bootinfo greatly simplifed. temp_boot_osid has been added to allow for
      temporary booting of different kernels (such as with ndoe_admin or
      create_image). Unlike next_boot_osid which is a one-shot boot,
      temp_boot_osid causes the node to boot that OS until told not too.
      
      next_boot_path and def_boot_path in the nodes table are now ignored.
      Bootinfo gets path info strictly from the os_info table entry for the osid
      given in one of def_boot_osid, temp_boot_osid, or next_boot_osid.  This
      makes the selection of what to do in bootinfo a lot simpler (and for
      TBBootWhat in libdb). The os_info table also modified to include an MFS
      flag so that bootinfo knows to tell the client that the path refers to an
      MFS and not a multiboot kernel.
      
      Change to boot sequence; free nodes no longer boot into the default OSID.
      Instead, they are told to wait in pxeboot until told what to do, which
      will typically be when the node is allocated and a specific OSID
      picked. If the node needs to be reloaded, then the node is told to jump
      directly into the Frisbee MFS, which saves one complete reboot cycle
      whether the node has the requested OS installed, or not.  New program
      added called "bootinfosend" that is used by node_reboot to "wake up" up
      nodes sitting in pxewait mode, so that they query bootinfo again and boot.
      
      node_reboot changed to look at the event state of a node, and use
      bootinfosend to wake up nodes, rather then power cycle, since pxeboot does
      not repsond to pings. Retry (if the UDP packet is lost) is handled by
      stated.
      
      Event support added to bootinfo, to replace the event generation that was
      in proxydhcp. I have not included the caching that Mac had in proxydhcp
      since it does not appear that bootinfo packets are lost very
      often. Cleaned up all of the event and DB queury code to use lib/libtb for
      DB access, and moved all of the event code into a separate file.  The
      event sequence when a node boots now looks like this:
      
      	'SHUTDOWN'    --> 'PXEBOOTING'  (BootInfo)
      	'PXEBOOTING', --> 'PXEBOOTING'  (BootInfo Retry)
      	'PXEBOOTING', --> 'BOOTING'     (Node Not Free)
      	'PXEBOOTING', --> 'PXEWAIT'     (Node is Free)
      	'PXEWAIT',    --> 'PXEWAKEUP'   (Node Allocated)
      	'PXEWAKEUP',  --> 'PXEWAKEUP'   (Bootinfo Retry)
      	'PXEWAKEUP',  --> 'PXEBOOTING'  (Node Woke Up)
      
      Change stated to support resending PXEWAKEUP events when node times out.
      After 3 tries, node is power cycled. Other minor cleanup in stated.
      
      Clean up and simplify os_select, while adding support for temp_next_boot
      and removing all trace of def_boot_path and next_boot_path processing.
      Remove all pxe_boot_path and next_pxe_boot_path processing.  Changed
      command line interface to support "clearing" fields. For example,
      node_admin changed to call os_select like this to have the node
      temporarily boot the FreeBSD MFS:
      
      	os_select -t FREEBSD-MFS pcXXX
      
      which sets temp_boot_osid. To turn admin mode off:
      
      	os_select -c -t pcXXX
      
      which says to clear temp_boot_osid.
      
      sql/database-fill-supplemental.sql modifed to add os_info table
      entries for the FreeBSD, Frisbee, and newnode MFS's.
      
      Be sure to change dhcpd config, restart dhcp, kill proxydhcp, restart
      bootinfo,

      Uniform syslog'ing. Change everything I could find to use a syslog facility · cc6d6fa7
      Mike Hibler authored
      as defined in the defs-* file (e.g. "TBLOGFACIL=local2").  The default is
      "local5" which is what we are setup to use so you shouldn't need to mess
      with your defs- file!
      
      perl scripts just get this value configured in when configure is run.
      C programs get the value in two ways.  For programs that are intimate with
      the testbed infrastructure, and include "config.h", they just get it from
      that file.  For programs that we sometimes use outside the Emulab build
      environment (e.g., frisbee, capture) and that don't include config.h,
      the value is set via a "-DLOG_TESTBED=..." in the GNUmakefile build line.
      If the value isn't set, it defaults to what it used to be (usually LOG_USER).
      
      Still to do: healthd, hmcd (whose build doesn't seem to be completely
      integrated) and plabdaemon.in (since its icky python :-)

      Small fix for perl oddity. Note to self: Do not expect $myhash{TB_CONSTANT_SUB} to work since it evals TB_CONSTANT_SUB as a string unless you force it to be an expression (ie with parens).

      Merge the newstated branch with the main tree. · 5c961517
      Mac Newbold authored
      Changes to watch out for:
      
      - db calls that change boot info in nodes table are now calls to os_select
      
      - whenever you want to change a node's pxe boot info, or def or next boot
      osids or paths, use os_select.
      
      - when you need to wait for a node to reach some point in the boot process
      (like ISUP), check the state in the database using the lib calls
      
      - Proxydhcp now sends a BOOTING state for each node that it talks to.
      
      - OSs that don't send ISUP will have one generated for them by stated
      either when they ping (if they support ping) or immediately after they get
      to BOOTING.
      
      - States now have timeouts. Actions aren't currently carried out, but they
      will be soon. If you notice problems here, let me know... we're still
      tuning it. (Before all timeouts were set to "none" in the db)
      
      One temporary change:
      
      - While I make our new free node manager daemon (freed), all nodes are
      forced into reloading when they're nfreed and the calls to reset the os
      are disabled (that will move into freed).
