release/005.009 (2017-07-07) 

    [ntp] Push "tinker-panic 0" to the top of the ntp.conf file to help 
    address the timekeeping problem with vmware. This means always reset
    the clock, even if the new time is more than 1000s away from the 
    current system time. [ljlgeek]

    [ssh] Add $max_sessions options. [adamhl]

    [iptables] Ensure that port numbers are converted to strings inside
    the rules erb file to avoid Ruby errors. [adamhl]

    [kerberos] Allow kerberos kinit port number override for the "custom"
    version of krb5.conf. Needed for the non-production kerberos
    environments that don't use port 88. [adamhl]

    [kerberos] Add option to completely override /etc/krb5.conf using
    the parameter 'source'. [adamhl]
    [kerberos] Add a new defined resource type that makes it easier to
    setup a krb5.conf file. The defined resource type is
    base::kerberos::krb5_conf [adamhl]
    [newsyslog] Pull out filter-syslog from newsyslog so filtersyslog can
    be used separately from newsyslog. [adamhl]

    [ssh] Change the method by which we specify a list of sunetids too
    filter via filter-syslog. If you install this version of base you will
    need to add to hiera the list of sunetids whose authentication failure
    warnings you want to continue ignoring. Otherwise, your root mail get
    noisier. Because this only affects filter-syslog it has no affect on
    the actual ssh service running on the server, so it is a very
    low-impact change. [adamhl]

    [ssh] Ignore a couple more innocuous sshd log lines. [adamhl]

    [ssh] Add the parameter $pubkey to the ssh class to allow ssh key-pair
    logins (this way you do not have to do class inheritance). Also add a
    parameter to allow root users to login using ssh key-pairs. Both of
    these parameters are set to have no effect by default. [adamhl]

    [ssh] Add the parameter $ip_ranges. This is an array of iptable
    addresses that are allowed to access port 22 on this server. [adamhl]

release/005.006 (2017-02-16)

    [kerberos] Add support for the new kerberos environment 'qa'. [adamhl]

release/005.005 (2017-02-02)

    [kerberos] Add the option rdns_enabled so that Kerberos can be
    configured not to require clients to do a reverse DNS lookup on the

    hostname of a service principal. The default is set to true, so unless
    specifically overridden to false Kerberos clients will behave as they
    always have. [adamhl]

    [kerberos] Change the master_kdc setting in krb5.conf to point to an
    alias of the master (kerberos1). This will not change how the
    configuration works, but makes it easier to change the ordering of the

    replicas if, in the future, we need to. [adamhl]
release/005.004 (2017-01-09)

    [os] Change the exec resource in the 'aptitude' staged
    base::os::debian::apt class to have the name 'apt config aptitude
    update' so that it will not interfere with other exec's of the same
    name in the 'main' stage. [adamhl]

release/005.002 (2016-12-13)

    [ssh] Change the class "ssh::pam" to "base::ssh::pam".  This should
    only affect people who are setting ssh::pam variables via Hiera, or
    via class parameters.  Clients setting base::ssh variables in any
    way are not affected. [akkornel]

    [ssh] Add support for the pam_slurm module.  This is for clients using
    the SLURM job scheduler, and who want to prevent users from logging in
    without an allocation.  This is disabled by default.  Also add the
    pam_slurm_bypass parameter, which is a file containing a list of users
    (one per line) who should not be blocked by pam_slurm. [aseishas]

    [syslog] On Ubuntu, have files and directories by owned by the
    "syslog" user, and the "adm" group.

    [wallet] When running inside a Packer build, do not attempt to retrieve
    things from wallet. [akkornel]

    [os::debian] More @ symbols into ERB templates. [akkornel]


    Add "path" attributes to several exec resources. This will be required
    in the next version of Puppet. [adamhl]

    [puppetclient] Replace "local" variables in ERB templates with what is
    really intended: instance variables defined in the calling manifest
    (or defined as a Puppet fact). While currently not strictly necessary,
    in a future version Puppet will stop interpreting ERB local variables
    as instance variables, so we might as well fix them now. Furthermore,
    when using "puppet apply" incorrect use of variables in templates
    generates ugly red warnings, so fixing these now makes "puppet apply"
    happier. [adamhl]

    [puppetclient] Remove some conditional code that made sense when we
    used very old versions of Puppet. [adamhl]

    [ssh, syslog, xinetd] More instance variable cleanup. [adamhl]
    [ipmi] When comparing lsbmajdistrelease to a Debian version, convert
    lsbmajdistrelease to an integer first (otherwise, get Ruby
    error). [adamhl]
    [os/debian] Add parameter to allow the option of *not* including the
    debian-stanford backports repository in the apt sources. [adamhl]
release/005.000 (2016-11-21)

    This release has a number of breaking changes.

    [duo] base::duo has been completely reworked into a type plus a common
    class.  Clients which use Duo for their own purposes should create an
    instance of base::duo::config, which will create a Duo PAM config file for
    them to use.  See README.duo for more information.

    [ipmi] A complete rework of base::ipmi.      The base::noipmi class no
    longer exists.  Instead, IPMI support should be disabled by setting
    base::ipmi::ensure to "absent".  IPMI kernel modules, and ipmievd, should
    still be automatically disabled on virtual systems, even when
    "ensure => present"; in those cases, the IPMI client tools will still be
    installed.  Code has been updated for Debian 8 and Ubuntu 16.04.

    [os/debian] All aptitude operations are now performed in a new phase,
    called "aptitude".  The "aptitude" phase is configured to run before
    "main".

    Clients which rely on aptitude being up-to-date must no longer
    "require => Exec['aptitude update']".  The nature of Puppet phases will
    ensure that aptitude is already updated.

    Clients installing their own custom sources are advised to move all of that
    into separate classes, and to put those classes into a new phase of their
Adam Lewenberg's avatar
Adam Lewenberg committed
    own.  This new phase should "require => Stage['aptitude']" and
    "before => Stage['main']", to ensure proper execution sequencing.

    [os/debian] Add two Hiera-configurable parameters to base::os::debian::apt:

    * apt_cache_notin_tmp.  If true, use a different directory to store package
    scripts that need to be run during package install/upgrade.

    * apt_cache_tmp_dir.  When apt_cache_notin_tmp is true, this is the
    directory to use for package scripts.

    [os/debian] Install the stanford-server package (this might trigger a
    duplicate resource error if currently installed by other classes).

    [postfix/sender] A new type: base::postfix::sender.  This is similar to
    base::postfix::recipient, except it is used to rewrite sender addresses
    instead of recipient addresses.

    It is suggested that clients use base::postfix::sender to ensure that
    emails sent 'from' "root@stanford.edu" or "root@hostname.stanford.edu" are
    instead being sent 'from' either "noreply@stanford.edu" or
    "shared-mailbox@stanford.edu".

    [ssh] A fairly large rework of SSH code.  Support has been added for
    treating "alternate accounts" (.root, .admin, root., and admin.) the same
    as root.  Code has also been updated to account for changes to base::duo.
    Support has also been added to completely disable password authentication.
    Support for Ed25519 keys is also included (though disabled by default).
    Finally, pam_afs is now configurable: It can be disabled on systems that do
    not use AFS.

    See README.ssh for more information on how to use the code.

    [sudo] Complete rework of base::sudo, including configurable support for
    Duo.  Anyone in the "sudo" or "wheel" group gets sudo access.  If Duo is
    enabled, anyone on a specified list is able to sudo without a password, but
    with a two-step run.  Fail-secure is supported, as is using the GECOS field
    to specify the username that Puppet should actually use.

    See README.sudo for more information on how to use the code.

    [syslog] Some fixes for Ubuntu.

    [os/debian] Fix the $PATH used by aptitude.

    [puppetclient] Fix a filter-syslog regex error.
