      ZFS change; when ZFS_NOEXPORTS is on, we have to call exports_setup · b9ec1a54
      Leigh B Stoller authored
      when a user logs in so that their home directory and projects are exported
      from ops. Otherwise things break.
      
      Since we really do not want to do this too often, exports_setup is
      exporting anyone who is logged in within the last week, and the web
      interface is calling out to exports_setup only once a day for each user.
      
      This can be "improved" but I am worried we are fighting a losing battle and
      will eventually yank this code anyway.

      Large set of changes for using the Geni trusted signer tool, to · 980f6cbd
      Leigh B Stoller authored
      authenticate Geni users to CloudLab (who do not have Emulab accounts).
      CloudLab users must have an account to do anything (unlike APT which allows
      guest users). But instead of requiring them to go through the Emulab
      account creation (high bar), let then use their Geni credentials to prove
      who they are. We then build a local account for that new user, and save off
      the speaksfor credential so that we can act on their behalf when talking to
      the backend clusters (and their MA to get their ssh keys).
      
      These users do not have a local account password, so they cannot log into
      the web interface using the Emulab login page, nor do they have a shell on
      ops.
      
      Once authenticated, we put the appropriate cookies into the browser via
      javascript, so they can use the Cloud (okay, APT) web interface (they
      appear logged in).
      
      I make use of the nonlocal_id field of the users table, which was not being
      used for anything else. Officially, these are "nonlocal" users in the code
      (IsNonLocal()).
      
      When a nonlocal user instantiates a profile, we use their speaksfor
      credential to ask their home MA for their ssh keys, which we then store in
      the DB, and then provide to the aggregate via the CreateSliver call.
      Note that no provision has been made for users who edit their profile and
      add keys; I am not currently expecting these users to stumble into the web
      interface (yet).

      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).

      Finish up user deletion. The big visible change is that when a user is · 2965922b
      Leigh B Stoller authored
      deleted, they still remain in the user table with a status of
      "archived", but since all the queries in the system now use uid_idx
      instead of uid, it is safe to reuse a uid since they are no longer
      ambiguous. 
      
      The reason for not deleting users from the users table is so that the
      stats records can refer to the original record (who was that person
      named "mike"). This is very handy and worth the additional effort it
      has taken.
      
      There is no way to ressurect a user, but it would not be hard to add.

      do this the PAGEHEADER call needed to be moved to after

      warning will be printed if either CheckLoginOrDie or
      Required/OptionalPageArguments detects that PAGEHEADER was already
      called.
      
      Also change the redirect in kb-show to be a permanent redirect (301)
      rather than a temporary one (302) which is the default unless a status
      code is given.

      A little auth module plugin I wrote to allow cross-domain login from · fc9aae80
      Leigh B. Stoller authored
      emulab to the protogeni wiki, but I use it for all of the wikis. The
      basic idea is that the emulab backend inserts a hash value into the
      cookie table in the trac DB on ops (via ssh). Then Emulab issues a
      redirect over to the trac wiki, with the uid/hash values as arguments
      to the xlogin URL. This hash is use-once; if it exists in the cookies
      table, it is deleted and a new one generated by the underlying auth
      module, and a cookie returned to the browser. The user is thus logged
      in for all subsequent access.
      
      Why? Cause emulab.net cannot insert auth cookies for protogeni.net, so
      must let the auth module inside trac insert the cookie.

      * Replace the argument processing code in all pages. Currently we rely on · 48acc8e3
      Leigh B. Stoller authored
        register_globals=1 to turn POST/GET/COOKIES arguments in local variables.
        This is known to be a terrible security risk, and we keep saying we are
        going to fix it, and now I am. In order to accomplish this on a
        transitional basis (since I don't want the entire web interface to stop
        working while I debug it), and because the code just needs the cleanup, I
        am doing it like this: Each page will sport new declarations at the top:
      
      	RequiredPageArguments("experiment", PAGEARG_EXPERIMENT,
                                    "template",   PAGEARG_TEMPLATE,
                                    "instance",   PAGEARG_INSTANCE,
                                    "metadata",   PAGEARG_METADATA,
                                    "osinfo",     PAGEARG_OSINFO,
                                    "image",      PAGEARG_IMAGE,
                                    "project",    PAGEARG_PROJECT,
                                    "group",      PAGEARG_GROUP,
                                    "user",       PAGEARG_USER,
      			      "node",       PAGEARG_NODE,
      			      "yesno",      PAGEARG_BOOLEAN,
      			      "message",    PAGEARG_STRING,
      			      "age",        PAGEARG_INTEGER,
                                    "cost",       PAGEARG_NUMERIC,
                                    "formfields", PAGEARG_ARRAY,
                                    "unknown",    PAGEARG_ANYTHING);
      
      	OptionalPageArguments("canceled", PAGEARG_BOOLEAN);
      
        The first token in each pair is the name of the global variable to
        set, and the second token is the type. So, for "experiment" we look at
        the URL for a pid/eid or exptidx, etc, sanity check them (safe for a
        DB query), and then try to find that experiment in the DB. If it maps
        to an experiment, set global variable $experiment to the object. Since
        its a required argument, produce an error if not supplied. Similar
        treatment for optional arguments, with the obvious difference.
      
        The goal is to have ALL argument processing in one place, consistent,
        and correct. I've found numerous places where we leak unchecked
        arguments into queries. It also cuts out a lot of duplicated code.
      
      * To make the above easier to deal with, I've been replacing lots of
        hardcoded URLS in the code of the form:
      
      	foo.php3?pid=$pid&eid=$eid ...
      
        with
      
              CreateURL("foo", $experiment)
      
        which creates and returns the neccessary url string, by looking at
        the type of its arguments (experiment, template, instance, etc.)
      
        Eventually plan to replace them all so that URL handling throughout
        the code is all defined in one place (all the new URL code is in
        url_defs.php).
      
      * I have cranked up error reporting to tell me anytime a variable is
        used before it is initialized, plus a bunch of other stuff that PHP
        deems improper. Think of it like -Wall ... and boy we get a lot of
        warnings.  A very large percentage of the diffs are to fix all these
        warnings.
      
        The warnings are currently going to /usr/testbed/log/php-errors.log,
        and I'll be adding a script to capture them each night and mail them
        to tbops. This file also gets errors (this will be a change for
        developers; rather then seeing errors and warnings dumped in the
        middle of web pages, they will go to this file instead).
      
      * Major refactoring of the code. More objects (nodes, images, osids).
        Moving tons of queries into the objects in the hopes of someday
        getting to a point where we can split the web interface onto a
        different server.  Lots of general cleanup.
