      A bunch of boot changes. Read carefully. · 94ccc3f4
      Leigh B. Stoller authored
      * Add boot_errno to the nodes table so that nodes can report in a
        subcode to indicate what went wrong. At present, we do not report any
        real error codes; that is going to take some time to work out since it
        will reqiure a bunch of changes to the boot scripts.
      * Add new table node_bootlogs to store logs provided by the nodes. Not
        a full console log, but a log of the tmcd client side part. We can
        make it a full log if we want though; just means mucking about with
        the boot phase a bit.
      * Add new state transition to NORMALv2 and PCVM state machines. "TBFAILED"
        is a new state that is sent (after TBSETUP) if a node fails somewhere in
        the tmcd client side.
      * Change TBNodeStateWait() to take a list of states (instead of single
        state) and an optional pass by reference parameter to return the actual
        state that the node landed in. Change all calls to TBNodeStateWait() of
      * Change os_setup (and libreboot in wait mode) to look for both TBFAILED
        and ISUP. If a TBFAILED event is seen, we can terminate the wait early
        and not retry os_setup on physical nodes (although still retry virtual
        nodes). The nice thing about this is that the wait should terminate much
        earlier (rather then waiting for timeout), especially for virtual nodes
        which can take a really long time when there are a couple of hundred.
      * Add new routines dobooterrno() and dobootlog() to tmcd. Bump version
        number and increase the buffer size to allow for the larger packets that
        a console log wikk generate (added MAXTMCDPACKET variable, set to 0x4000).
      * Add new -f option to tmcc to specify a datafile to send along as the last
        argument to tmcd. This is more pleasing then trying to send a console log
        in on the command line. For example: "tmcc -f /tmp/log BOOTLOG" will send
        a BOOTLOG command along with the contents of /tmp/log.
        Also close the write side of the pipe so that server sees EOF on
        read. See aside comment below.
      * Changes to rc.bootsetup:
           1. Use perl tricks to capture all output, duping to the console and to
              a log file in /var/emulab/logs.
           2. On any error, send a status code (boot_errno) and the bootlog to
           3. Generate a TBFAILED state transition.
      * Changes to rc.injail:
           1. Same as rc.bootsetup, but do not send log files; that would pummel
              boss. Leave them on the physical node.
      * Change vnodesetup (which calls mkjail) to watch for any error and send a
        TBFAILED state transition. This should catch almost all errors, and
        dramatically reduce waiting when something fails.
      * Changes to rc.cdboot are essentially the same as rc.bootsetup, although a
        bootlog is sent all the time (success or failure), and I do not generate
        a boot_errno yet. Also, instead of TBFAILED, generate a PXEFAILED state
        since the CDROM is actually operating within the PXEFBSD opmode. I have
        yet to work this into the rest of the system though; waiting to get a new
        CD built and actually experiment with it.
      * Add new menu option and web page to display the node bootlog. We store
        only the lastest bootlog, but maybe someday store more then one. Display
        boot_errno on node page.
      Aside: I made a big mistake in the tmcd protocol; I did not envision
      passing more then a small amount of data (one fragment) and so I do not
      include a record terminator (ie: close of the write side on the client
      sends EOF) or a size field at the beginning. No big deal since small
      requests are sent in one fragment and the server sees the entire
      thing. Well, with a large console log, that will end up as multiple
      fragments, and the server will often not get the entire thing on the first
      read, and there are no subsequent reads (with no EOF or known size, it
      would block forever). Well, fixing this in a backwards compatable manner
      (for old images) was way too much pain. Instead, tmcc now closes the write
      side, and the server does subsequent reads *only* in the new dobbootlog()
      routine. Note that it *is* possible to fix this in a backwards compatable
      manner, but I did not want to go down that path just yet.

      places. Change $short optional argument to a flags argument, and add a
      NOPERM flag, which allows display of a node to people without
      permission to view that node. The display is cut back to node type,
      and a couple of other things that are not private. I also added a
      section on the Interfaces of a node, using the interfaces table for
      the node, joined with the interface_types and interface_capabilities
      tables. This gives more specific information about a node then is
      possible using the generic node_types table.

      Reorg of two aspects of node update. · 2641af4d
      Leigh B. Stoller authored
      * install-rpm, install-tarfile, spewrpmtar.php3, spewrpmtar.in: Pumped
        up even more! The db file we store in /var/db now records both the
        timestamp (of the file, or if remote the install time) and the MD5
        of the file that was installed. Locally, we can get this info when
        accessing the file via NFS (copymode on or off). Remote, we use wget
        to get the file, and so pass the timestamp along in the URL request,
        and let spewrpmtar.in determine if the file has changed. If the
        timestamp it gets is >= to the timestamp of the file, an error code
        of 304 (Not Modifed) is returned. Otherwise the file is returned.
        If the timestamps are different (remote, server sends back an actual
        file), the MD5 of the file is compared against the value stored. If
        they are equal, update the timestamp in the db file to avoid
        repeated MD5s (or server downloads) in the future. If the MD5 is
        different, then reinstall the tarball or rpm, and update the db file
        with the new timestamp and MD5. Presto, we have auto update capability!
        Caveat: I pass along the old MD5 in the URL, but it is currently
        ignored. I do not know if doing the MD5 on the server is a good
        idea, but obviously it is easy to add later. At the moment it
        happens on the node, which means wasted bandwidth when the timestamp
        has changed, but the file has not (probably not something that will
        happen in typical usage).
        Caveat: The timestamp used on remote nodes is the time the tarfile
        is installed (GM time of course). We could arrange to return the
        timestamp of the local file back to the node, but that would mean
        complicating the protocol (or using an http header) and I was not in
        the mood for that. In typical usage, I do not think that people will
        be changing tarfiles and rpms so rapidly that this will make a
        difference, but if it does, we can change it.
      * node_update.in, client side watchdog, and various web pages:
        Deflated node_update, removing all of the older ssh code. We now
        assume that all nodes will auto update on a periodic basis, via the
        watchdog that runs on all client nodes, including plab nodes.
        Changed the permission check to look for new UPDATE permission (used
        to be UPDATEACCOUNT). As before, it requires local_root or better.
        The reason for this is that node_update now implies more than just
        updating the accounts/mounts. The web pages have been changed to
        explain that in addition to mounts/accounts, rpms and tarfiles will
        also be updated. At the moment, this is still tied to a single
        variable (update_accounts) in the nodes table, but as Kirk requested
        at the meeting, it will probably be nice to split these out in the
        Added the ability to node_update a single node in an experiment (in
        addition to all nodes option on the showexp page). This has been
        added to the shownode webpage menu options.
        Changed locking code to use the newer wrapper states, and to move
        the experiment to RUNNING_LOCKED until the update completes. This is
        to prevent mayhem in the rest of the system (which could be dealt
        with, but is not worth the trouble; people have to wait until their
        initiated update is complete, before they can swap out the
        Added "short" mode to shownode routine, equiv to the recently added
        short mode for showexp. I use this on the confirmation page for
        updating a single node, giving the user a couple of pertinent (feel
        good) facts before they comfirm.

      Commit SSH node menu option, and support. Heavily based/borrowed from · f4bf9b5c
      Leigh B. Stoller authored
      Chad's tiptunnel stuff. Requires ssh-mime.pl in the current directory,
      to be installed as a browser helper application on the users machine.
      Copied Chad's instructions for the tiptunnel from the FAQ, and stuck
      it into ssh-mime.html as a help file (not really FAQ material). The
      intent of this of course is to make ssh into jailed nodes easier, but
      not having to know port numbers, or directly log into ops first, when
      the jails are using control network IPs in our private IP space (not
      routable from outside).

      Big round of image/osid changes. This is the first cut (final cut?) at · a73e627e
      Leigh B. Stoller authored
      supporting autocreating and autoloading images. The imageid form now
      sports a field to specify a nodeid to create the image from; If set,
      the backend create_image script is invoked. Thats the easy part.
      Slightly harder is autoloading images based on the osid specified in
      the NS file. To support this, I have added a new DB table called
      osidtoimageid, which holds the mapping from osid/pctype to imageid.
      When users create images, they must specify what node types that image
      is good for. Obviously, the mappings have to be unique or it would be
      impossible to figure it out! Anyway, once that image mapping is
      in place and the image created, the user can specify that ID in the NS
      file. I've changed os_setup to to look for IDs that are not loaded,
      and to try and find one in the osidtoimageid. If found, it invokes
      os_load. To keep things running in parallel as much as possible,
      os_setup issues all the loads/reboots (could be more than a single set
      of loads is multiple IDs are in the NS file) at once, and waits for
      all the children to exit. I've hacked up os_load a bit to try and be
      more robust in the face of PXE failures, which still happen and are
      rather troublsesome. Need an event system!
      Contained in this revision are unrelated changed to make the OS and
      Image IDs per-project unique instead of globally unique, since thats a
      pain for the users. This turns out to be very messy, since underneath
      we do not want to pass around pid/ID in all the various places its
      used. Rather, I create a globally unique name and extened the OS and
      Image tables to include pid/name/ID. The user selects pid/name, and I
      create the globally unique ID. For the most part this is invisible
      throughout the system, except where we interface with the user, say in
      the web pages; the user should see his chosen name where possible, and
      the should invoke scripts (os_load, create_image, etc) using his/her
      name not the internal ID. Also, in the front end the NS file should
      use the user name not the ID. All in all, this accounted for a number
      of annoying changes and some special cases that are unavoidable.
