constructed it is possible that assign will place the "lannode" on one node and all the other interfaces on another node (trivial lan). This is dealt with by the "virtpatch" code, that according to the comments, "only Rob and Leigh understand." Wish that were true! Anyway, when this happens, NewVirtIface never gets called with an underlying physical interface (which signals it to set the current_speed on the interface), so the current_speed is left at zero. Not good. So, in PatchVirts (which installs the vinterfaces for that lannode), also set the current_speed on the underlying phys interface. This stuff is totally bizarre, certain to break some other special case of the hundreds of special case in assign_wrapper. Oh, the code was easy, but testing it was a pain since assign is so random; it only rarely splits the lan up in the above manner.

our slice prefixes could be anything. Thus, have to ensure non-root group users can't overwrite /etc/slicename, and grab the slicename (also the name of the user we allow to run vnodesetup, if not real root). Ugh.

to info in /etc/emulab/waconfig. Pretty much like how planetlab does it -- each node's dongle has to have a specific set of info. The key difference from plab is that widearea nodes that boot off dhcp don't have to have this file -- if it doesn't exist, they do everything via dhcp and then tmcc just like normal.

and non-admins in projects that have users in both categories (mostly emulab-ops, tbres and testbed). The new order says that if the swapper of an active experiment is an admin, only other admins have their accounts (and homedirs) propagated to the experiment. Analogous for non-admin experiments. Add DYNAMICROOTPASSWORDS, default to true, which causes the root passwords on emulab images to be changed each time they are allocated to an experiment. This is to prevent the same password on every node for years at a time!

(and vnodes). Each time a node is allocated to an experiment it gets a new root password (using the node_attributes table). The watchdog has a new section that resets the root password (defaults to hourly). We still using a common password in the image to avoid totally bricking ourselves, but once a node boots into an experiment it gets a new root password. This prevents hundreds of nodes with the same password, and all of the problems associated with that.

returns the hash of the password that is stored in the DB (or generates a new one if one does not exist, and then stores it). Bumped the version number too since I added an interval for it to the watchdoginfo command. This stuff can run on the server, does not affect existing images.

vservers can be configured with experimental interfaces. Think duct tape and baling wire here... * commmon/bootvnodes: did some code refactoring in anticipation of something that was never needed. Oh well, it looks purdy anyway! * common/libsetup.pm: LINUXJAILED() predicate to indentify local Linux vserver setups. getlocalevserver() to return the IP/hostname of the "local" event server. * common/rc.{linktest,linkagent,progagent,trace,trafgen}: use the getlocalevserver() function for use with -s options (Linux vserver based vnodes cannot bind to localhost to talk to the pnode pubsubd) * common/config/rc.ifconfig: run this for Linux vservers, put out iface map for veths as well as physical interfaces * common/delaysetup: add -j vnodeid option, will need this at some point * linux/liblocsetup.pm: veth (actually etun) setup for Linux vserver vnodes * linux/mkvserver.pl: first cut at getting interfaces configured in vservers, do all the necessary etun/br plumbing (NOT a pretty sight...) * linux/vserver/rc.invserver (moved here from linux/rc.invserver): run linktest in local vservers (though it won't run yet due to NFS problems in vservers) * linux/vserver/vserver-cnet.sh: statically configure the control net in a vserver, no DHCP here! * linux/vserver/vserver-{init,rc}.sh: two parts of the Funky Interface Setup Dance that run inside the vserver
