      Further overhaul of firewall code. NOTE: required bump of tmcd version to 34. · 6a26b246
      Mike Hibler authored
      Firewalls now work with nodes which require a subboss. Had to introduce new
      firewall rules which skipped around the checks that no packets to/from
      node control net IPs should pass through the firewall, if the IP in question
      belongs to a subboss (since subboss is on the node control network). It
      actually checks for all Emulab servers (boss, ops, fs or any subboss),
      so the code should work for an Emulab install which has a non-segmented
      control network in which all servers were in the same subnet as the nodes.
      In addition to the new rules, we also had to pass in additional information
      via "tmcc firewallinfo" giving the IP/MAC of those server nodes that are on
      the node control network. We use this to establish ARP entries on the
      inside network so that nodes can find the servers. Since the existing
      client-side firewall code in would blow up if it got a line
      that it didn't recognize, I had to bump the tmcd version number and add
      some conditional code to tmcd.c:dofwinfo() to not return the extra info for
      old versions.
      Added a couple of new firewall variables EMULAB_BOSSES and EMULAB_SERVERS
      that are used in the new rules. Fixed the support scripts in firewall/
      to properly initialize these variables.
      IMPORTANT: tmcd looks up boss, ops, fs, and subbosses in the interfaces
      table to find their IPs and MAC addresses. By default, we do not create
      such interface table entries for boss/ops/fs. We have them at Utah for
      other reasons. These entries are only needed if you have a non-segmented
      control network (or a subboss) and you want to firewall such nodes.
      The script to initialize the firewall variables ( will
      print out a warning for configurations that are affected and don't have
      the entries.

      Don't tag the native VLAN in setVlansOnTrunk() for dual-mode. · 6935a180

      If the change to a dual-mode trunk port involves the "native vlan",
      make sure we don't make it a tagged vlan like we do any other VLANs.

      A couple of fixes for the FreeBSD 8.x-based MFSes. · c4a46533

      We apparently were not setting GID/EGID quite right in runstartup, it was
      dropping a group. If that group happened to be "wheel", then any command
      requiring "sudo" would fail. Now we set GID and EGID according to the letter
      of the law.
      If mount of a Linux FS fails, run e2fsck and try again. BSD cannot mount
      a Linux FS if the ext3 journal requires recovery. e2fsck will handle that.
