Log:
Medium size cleanup of the client side code. The main impetus behind
this was to add soft reconfig support so that nodes could be
reconfigured without having to reboot them. This appears to work, and
has been tested with jails getting moved around. I've also tested the
new code on the MFS, but still no testing has been done on PLAB nodes.
The main change is that most of the code moved out of libsetup.pm, and
was split into constituent rc scripts, each of which does its own
thing, including cleaning up and preparing for making an image. Most
of that central knowledge has been moved out into the scripts. Still more
to do but this was a good start.

Log:
Add new -f flag to assign_wrapper, and have tbswap use that flag when
tbswap is doing a swapretry (this happens during a normal swapin, when
a node fails). In this case, we want to fix all the nodes (overriding
user setting) when replacing failed nodes!

tbsetup assign_wrapper.in
Log:
Fix problem with trivial links not getting lindelays. In the case that
a 100Mb link is mapped to a trivial link, a linkdelay has to be
inserted since the actual loopback bandwidth is much higher. The
problem is that unlike other delays where requires_delay() will return
true, this decision has to wait until after assign does the mapping
and we find out that a link was mapped to a trivial link. When this
happens, I insert a linkdelay "on the fly" when processing the link
statements from assign.

Removed files:
tbsetup startexp.in webstartexp.in
Log:
* Removed startexp, and merged its contents into batchexp. There has been
no reason for the separation for a long time, and it made maintence more
difficult cause of duplication between batchexp and startexp (batch was
the sole user of startexp). Cleaner solution.
* Check argument processing for batchexp, swapexp, endexp to make sure the
taint checks are correct. All three of these scripts will now be
available from ops. I especially watch the filename processing, which was
pretty loose before and could allow some to grab a file on boss by trying
to use it as an NS file (scripts all runs as user of course). The web
interface generates filenames that are hard to guess, so rather then
wrapping these scripts when invoked from ops, just allow the usual paths
(/proj, /groups, /users) but also /tmp/$uid-XXXXXX.nsfile pattern, which
should be hard enough to guess that users will not be able to get
anything they are not supposed to.
* Add -w (waitmode) options to all three scripts. In waitmode, the backend
detaches, but the parent remains waiting for the child to finish so it
can exit with the appropriate status (for scripting). The user can
interrupt (^C), but it has no effect on the backend; it just kills the
parent side that is waiting (backend is in a new session ID). Log outout
still goes to the file (available from web page) and is emailed.

db nfree.in
Log:
Kill off all of the old osid handling that nfree did. When a node is
released, all of def_boot_osid,temp_boot_osid,next_boot_osid is cleared.
bootinfo currently uses the nodes free/alloc status to determine if the
node gets PXEWAIT, but will eventually switch to looking at the osids;
A node with no osids set (as will be when free) will go into PXEWAIT. This
will allow os_load of free nodes!
Change temporary locked pid/eid to a real pid/eid (emulab-ops/nfree-locked)
to avoid transient problems in tmcd, where isalive would cause tmcd to
core dump cause the reserved table had a nonexistent pid/eid setting.

tbsetup os_setup.in tbswap.in
Log:
Hacky changes for node reconfiguration, committed to branch only.
When reboot not selected for swapmod, set the nodes to RES_RECONFIG in
tbswap. In os_setup, nodes in RES_RECONFIG get a reconfig instead of
the reboot. Note that if reconfig fails (say, cause the image has no
reconfig script in it!), it node_reboot falls back to plain reboot
(note, node_reboot -r does the reconfig).
Problem: Not sure that pcvm nodes will always be moved out of ISUP and
so the wait for ISUP might terminate too soon.
Also some minor changes to make os_setup see the cancel flag and
hopefully end a lot sooner. These could go into the main branch if
desired

tbsetup node_reboot.in
Log:
Minor whackery. Add "-r" option to node_reboot to "reconfig" a pnode
instead of rebooting. If the reconfig fails, fail through to reboot.
A reconfig will "halt" the current vnodes (or remove ones that are no
longer assigned to the node) reconfig the pnode, and then restart the
vnodes that are still assigned to the node (or create new ones for
newly assigned vnodes). A halt stops the vnode, but leaves the
vnode filesystem intact.
Not bothering to reconfig individual vnodes yet since thats pretty
much like a reboot of a vnode. Difference in time is tiny.

Log:
Yet another fix which causes trouble when vnodes move around pnodes
arbitrarily. The code even though was written a long time back wasn't
tested coz of doing fix-node during modify. Without fix-node, vnodes
move around like crazy even if the ns file never changes in any way
during a modify. With this fix, as many vnodes that were previously
reserved, as possible, will be reused as long as assign ends up
using the same PCs as were reserved before.

Log:
Two changes for the commvirtsig branch only.
* Set the node cmd_line to the appropriate kernel when selecting a
jail or delay node host. Currently, jail (and sim) phosts get
/kernel.jail, and delay nodes get /kernel.delay. This is passed to
pxeboot via bootinfo, which boots the proper kernel, thus avoiding
the double reboot we all know and loathe.
WARNING: You have to use new (FBSD47-UPDATE) images for this to
actually work right, since the current default inage does not rename
the kernel after reboot. Mostly this will not be a problem, but it
might be.
Be sure to use tb-set-jail-os and tb-set-delay-os in your NS files
too (to FBSD47-UPDATE at least) for the same reason.
* My requires_delay() change from many weeks ago that needs more
testing before committing to main branch. Have faith all ye little

Log:
A new tb-* command tb-fix-current-resources 0/1 tells assign_wrapper
whether to do a fix-node of current resources or not. This is useful
when virtual node weights are changed during a swap modify. For
example, when a virtual node had a CPU desire of 10 and it became
800 during a swap modify, doing a fix-node on previous allocation
won't let assign do the correct thing and will sometimes cause
violations.
In order to support this, we need to move current reserved
pnodes/virtnodes to a holding experiment emulab-ops/oldreserved
and then back to current experiment. This was the solution that
