Release notes
=============


NEXT RELEASE
------------

Upgrade to Ansible 2.9.x, dropping support for Debian 8 Jessie,
upgrade to Python 3.x, dropping support for Python 2.7.

**Breaking changes:**

* Switched to Ansible 2.9.x, removing support for older versions. All
  documentation has been updated.
* Switched to using Python 3 on both controller and managed server
  side. Python 2.7 can no longer be used for this purpose. Support for
  WSGI applications running on Python 2.7 remains.

* All roles

  * Support for Debian 8 Jessie has been dropped.
  * Common parameters ``tls_private_key_dir`` and
    ``tls_certificate_dir`` are no longer used.
  * TLS private key and certificate parameters are now mandatory.

* ``bootstrap`` role

  * Parameter ``ansible_key`` is now mandatory.

* ``common`` role``

  * Minimum version of ``pip-tools`` in the ``pip_check_requirements``
    and ``pip_check_requirements_py3`` is now 5.3.0. This change was
    required in order to fix the deprecation warnings being sent out
    when the ``pip_check_requirements_upgrades.sh`` script is run.

* ``ldap_server`` role

  * Parameter ``ldap_server_domain`` is now mandatory.

  * Updated default set of TLS ciphers used by server
    (``ldap_tls_ciphers`` parameter). All CBC ciphers have been
    dropped. This could introduce incompatibility with older clients
    trying to connect to the LDAP server.

* ``mail_forwarder`` role

  * Use 2048-bit Diffie-Hellman parameters for relevant TLS
    ciphers. This could introduce incompatibility with older
    clients/servers trying to connect to the SMTP server.

* ``mail_server`` role

  * Use 2048-bit Diffie-Hellman parameters for relevant TLS
    ciphers. This could introduce incompatibility with older
    clients/servers trying to connect to the SMTP/IMAP server.

  * Updated default set of TLS ciphers used by IMAP/SMTP servers
    (``mail_server_tls_ciphers`` parameter). All CBC ciphers have been
    dropped. This could introduce incompatibility with older clients
    trying to connect to the IMAP/SMTP server.

* ``php_website`` role

  * Parameter ``enforce_https`` has been deprecated and
    removed. HTTPS is now mandatory in all cases.

* ``preseed`` role

  * Parameter ``ansible_key`` is now mandatory.

  * Parameter ``preseed_directory`` is now mandatory.

* ``web_server`` role

  * Use 2048-bit Diffie-Hellman parameters for relevant TLS
    ciphers. This could introduce incompatibility with older clients
    trying to connect to the web server.

  * Updated default set of TLS ciphers used by the server
    (``web_server_tls_ciphers`` parameter). All CBC ciphers have been
    dropped. This could introduce incompatibility with older clients
    trying to connect to the server.

  * Parameter ``default_enforce_https`` has been deprecated and
    removed. HTTPS is now mandatory in all cases.

* ``wsgi_website`` role

  * Parameters ``gunicorn_version`` and ``futures_version`` have been
    deprecated and removed. Existing roles should be updated to
    utilise the ``wsgi_requirements`` parameter instead.

  * Parameter ``enforce_https`` has been deprecated and
    removed. HTTPS is now mandatory in all cases.

  * Added parameter ``wsgi_requirements_in`` for listing top-level
    packages for performing pip requirements upgrade checks for
    Gunicorn requirements (listed via existing ``wsgi_requirements``
    parameter).

* ``xmpp_server`` role

  * Parameter ``xmpp_domains`` is now mandatory.

  * Use 2048-bit Diffie-Hellman parameters for relevant TLS
    ciphers. This could introduce incompatibility with older
    clients/servers trying to connect to the XMPP server.

  * TLS hardening is now applied to the *c2s* (client) connections on
    both the standard (``5222``) and legacy (``5223``) ports. Protocol
    version and ciphers are configurable via new
    ``xmpp_server_tls_protocol`` and ``xmpp_server_tls_ciphers``
    parameters with defaults enforcing TLSv1.2+ and PFS (perfect
    forward secrecy) ciphers.

  * Support for older Prosody versions (``0.9.x``) has been
    dropped. Only Prosody ``0.10.x`` is supported at the moment (due
    to missing Lua LDAP bindings in Debian 9 Stretch).

  * Support for running Prosody 0.11.x has been added. This is also
    the new default version of Prosody that gets deployed to the
    target system.

**Bug fixes:**

* ``common`` role

  * Run apticron at least once during initial installation to avoid
    accidental locking later on during the same playbook run.

* ``wsgi_website`` role

  * Deploy the requirement files used for upgrade checks to correct
    location when using Python 3. Previously the files would get
    deployed to directory dedicated to Python 2 version, which means
    the checks would be performed using Python 2 instead of Python 3.

**New features/improvements:**

* Tests have been updated to work with latest Molecule/Testinfra as
  part of the Ansible upgrade process.
* X.509 artefacts used during testing are now generated on the fly
  using `Gimmecert <https://gimmecert.readthedocs.io/>`_.

* ``mail_forwader`` role

  * The role now supports specifying the maximum mail message size
    limit for the SMTP server to accept via
    ``mail_message_size_limit`` role parameter.

* ``mail_server`` role

  * The role now supports specifying the maximum mail message size
    limit for the SMTP server to accept via
    ``mail_message_size_limit`` role parameter.

* ``xmpp_server`` role

  * Server now supports blocking users via `XEP-0191: Blocking Command
    <https://xmpp.org/extensions/xep-0191.html>`_.
  * Server now supports `XEP-0280: Message Carbons
    <http://xmpp.org/extensions/xep-0280.html>`_, letting multiple
    online XMPP clients receive/store the same message.
  * Server now supports `XEP-0313: Message Archive Management
    <https://xmpp.org/extensions/xep-0313.html>`_, storing copies of
    received messages server-side. Message expiration is configurable
    via parameter ``xmpp_server_archive_expiration``.
  * XMPP server certificate is checked on daily basis using the
    ``prosodyctl check certs`` command. This helps catch issues where
    issued certificate does not include all the necessary subject
    alternative names (this has also been documented in the role
    reference documentation).

**Deprecations:**

* ``backup_server`` and ``backup_client`` role

  * Officially dropped support for DSA keys (this was mainly remnant
    from Debian 8 Jessie support, on Debian 9 Stretch and upwards the
    DSA keys were not supported at all).


4.0.0
-----

A couple of smaller bug-fixes, and introduction of (minor) breaking
change related to handling of pip requirements upgrade checks in the
``common`` role (see below).

Breaking changes:

* ``common`` role:

  * Added separate parameter (``pip_check_requirements_py3``) for
    specifying dedicated Python 3 virtual environment package
    requirements used for package upgrade checks on (other
    user-provided) Python 3 virtual environments. If the existing
    ``pip_check_requirements`` parameter has been overridden, the new
    parameter will most likely need to be overridden in your site
    configuration as well. Take note that the new requirements will
    differ between Debian Jessie and Debian Stretch due to differnece
    in Python 3 minor version releases.

Bug fixes:

* ``backup_client`` role

  * Avoid errors related to lack of ``tty`` when invoking the GnuPG
    utility by using the ``--no-tty`` option.

* ``common`` role

  * Fixed problem with pip requirements upgrades checks outputting
    package list to stderr, causing the cron job to report outdated
    packages to administrator even though nothing is outdated (cron
    job treats anything output to stderr as worthy of notification).


3.1.0
-----

Minor improvements and fixes.

Breaking changes:

* ``common`` role:

   * Default values for the ``pip_check_requirements`` have changed to
     include ``pip`` and ``setuptools`` (and a couple more). It might
     be necessary to update any customised values of this parameter to
     match the default set of packages.

Bug fixes:

* ``common`` role

  * Use Python 3 in Python virtual environment used for checking if
    upgrades are available for Python requirements files. Fixes
    possibly incorrect package resolution due to wrong version of
    Python (for packages that have different dependencies based on
    Python version).

New features/improvements:

* ``common`` role

  * Changed how the packages are installed in Python virtual
    environments used for performing pip requirements upgrade checks,
    making the process more reliable. The packages in those dedicated
    environments are now fully pinned, including system packages such
    as ``setuptools`` and ``pip`` itself.

  * Changed the pip requirements checks to now take into account
    unsafe packages as well (such as ``setuptools`` and ``pip``) if
    listed.


3.0.0
-----

Upgrade to Ansible 2.7.x and full support for Debian 9 (Stretch).

Breaking changes:

* Switched to Ansible 2.7.x, removing support for older versions. All
  documentation has been updated.

* All roles

  * In order to avoid collision with reserved name, the variable for
    running the handlers explicitly has been changed from ``handlers``
    to ``run_handlers``. E.g. to run all handlers a command similar to
    ``ansible-playbook -t handlers -e run_handlers=true
    playbooks/site.yml`` should be used.

* ``ldap_server`` role

  * Custom LDAP module ``m_ldap_entry`` has been removed. Role uses
    the official ``ldap_entry`` and ``ldap_attr`` modules.

  * The ``ldap_entries`` parameter now supports only the states
    supported by ``ldap_entry`` module (e.g. ``append`` is not
    supported any longer - since it came with custom LDAP module).

* ``xmpp_server`` role

  * Installs Prosody nightly builds (default version 0.10) instead of
    latest stable. Change made to improve reproducability, and to
    avoid future breakages after new major/minor releases of
    Prosody. Prosody package name can be specified through the
    ``xmpp_prosody_package`` variable.

    This should most likely not break anything, but is included as
    possibly breaking change nevertheless since it is a big change in
    how Prosody is installed.

    This change had to be done because LDAP integration broke with
    Prosody 0.11 due to missing LDAP bindings for Lua 5.2. See
    `MAR-137: XMPP server LDAP integration not working for Prosody
    0.11.x
    <https://projects.majic.rs/majic-ansible-roles/issues/MAR-137>`_
    for more details.

New features/improvements:

* Tests have been updated to work with latest Molecule/Testinfra as
  part of the Ansible upgrade process.

* All roles

  * Full support for Debian 9 (Stretch) has been added to all roles.

* ``common`` role

  * The ``pip`` requirements upgrade checks are now performed once per
    day instead of once per hour.
  * The ``pip`` requirements upgrade checks now do not output warning
    in case deployed ``.in`` file does not have a matching ``.txt``
    file.
  * Certificate expiration check is less verbose. No mails are sent
    out any longer in case no certificates have been configured for
    checking, nor in cases where all certificates have passed the
    check. E.g. mails are sent out only in case some of the configured
    certificates will expire within next 30 days.

* ``wsgi_website`` role

  * Support for specifying Python version for Python virtual
    environment.


2.0.0
-----

Upgrade to Ansible 2.3.x, minor bug fixes and updates needed for the upgrade.

Breaking changes:

* Switched to Ansible 2.3.x, removing support for Ansible 1.9.x. All
  documentation has been updated.

* Due to switch to Ansible 2.x which is more restrictive when deploying code on
  remote server, it is now necessary to use one of the methods listed in
  `Ansible documentation
  <https://docs.ansible.com/ansible/latest/become.html#becoming-an-unprivileged-user>`_
  if connecting to remote server as user other than ``root``. Easiest fix is to
  enable ``pipelining``. Tests have been already updated to take advantage of
  this.

* ``ldap_server`` role

   * Renamed ``ldap_entry`` module to ``m_ldap_entry`` to avoid collision with
     official module.
   * Renamed ``ldap_permissions`` module to ``m_ldap_permissions`` to be
     consistent and to avoid potential future collisions with official module
     names.

* ``wsgi_website`` role

   * Removed handler with parametrised name used for restarting the web
     service. Dependent roles should instead define their own handlers from now
     on.

New features/improvements:

* Updated documentation to refer to Debian Jessie documentation where necessary.

* ``ldap_server`` role

  * Updated tests to be more resilient to ordering changes.

* ``mail_forwarder`` role

  * Updated tests to be more resilient to ordering changes and time races.

* ``backup_client`` role

  * Switched to using the ``file`` module when cleaning-up GnuPG backup keyring,
    which should make it more robust..

Bug-fixes:

* Updated pip requirements and its input file to include ``python-vagrant``
  (needed for Molecule tests).

* Updated handling of key ID extraction for OpenPGP keys in order for it to work
  with Ansible 2.x.

* Updated usage instructions in order to be able to install The Bug Genie via
  script, and added missing instructions for creating one of the directories for
  the demo wiki role (``handlers`` directory).

* All roles

  * Updated test playbooks to avoid idempotence test failures due to apt cache
    updates.

* ``backup_client`` role

  * Fixed scenario in which backup keys could not be properly replaced on Debian
    Stretch machines (due to more up-to-date version of GnuPG compared to Debian
    Jessie).

* ``common`` role

  * Fixed handling of complex version specifications when installing packages
    via pip. Needed for Ansible 2.x.

* ``wsgi_website`` role

  * Fixed handling of complex version specifications when installing packages
    via pip. Needed for Ansible 2.x.
  * Fixed erroneous calculation of adminstrator username in internal
    defaults parameter.


1.7.0
-----

Minor improvements for mail-related roles, internal refactoring of task syntax,
and improvements of tests.

New features/improvements:

* Documentation

  * Added new sub-section in development section describing some of the
    conventions used while developing the roles.

* All roles

  * Switched to using expanded syntax in all roles and cleaned-up the tasks a
    bit (mainly internal change).
  * Minor cleanups within tests and tasks to accomodate the syntax changes
    (mainly internal change).

* ``mail_forwarder`` role

  * Added parameter ``smtp_from_relay_allowed`` that controls if managed machine
    should accept incoming SMTP connections from the relay server. Useful for
    NAT'ed or laptop machines.
  * Added parameter ``smtp_relay_host_port`` that controls what port is used for
    connecting to the specified SMTP relay. Useful for machines behind
    restrictive ISPs.

* ``mail_server`` role

  * Introduced firewall rules to redirect from TCP port 27 to TCP port 25,
    useful for machines behind restrictive ISPs.


1.6.0
-----

Implemented full test suite with a plethora of smaller bug-fixes, and some minor
(internal) improvements.

Breaking changes:

* All roles

  * Previously a number of roles would modify permissions on the ``/srv``
    directory. This has now been fixed in order to prevent weird backup failures
    etc. Manual intervention is necessary on existing servers to fix the issue
    by changing the mode to ``0755`` (this is the usual default upon the OS
    installation).

* ``mail_server`` role

  * Since Postfix will now fall-back to using ``/etc/hosts`` if it cannot
    resovle a domain via DNS, some special care may be needed in case you have
    some unusual entries in ``/etc/hosts``. Normally this should not be an
    issue, though.

* ``backup_client`` role

  * Up to this point, if you had more than one additional encryption key
    specified in configuration, only the first one was taken into account. This
    is a major issue since it would render backups up to this point decryptable
    only with one of the keys. It is highly suggested to perform a full backup
    after upgrading to new version of Majic Ansible Roles via command::

      sudo duply main full

    This will ensure the most recent backup is decryptable with all additional
    keys!

New features/improvements:

* Added new documentation chapter dedicated to development.
* Added ``requirements.txt`` that can be used for installing the required
  packages in virtual environment (useful for development).
* Small fixes (mostly typos and such) throughout the documentation.

* All roles

  * Implemented tests using Molecule. See documentation for instructions on how
    to run tests.
  * Small internal refactorings to make things simpler and easier to maintain.

* ``common`` role

  * Added missing documentation for parameters ``pipreqcheck_uid`` and
    ``pipreqcheck_gid``.

* ``mail_server`` role

  * Updated Postfix configuration to fall-back to using ``/etc/hosts`` if DNS
    lookup fails. This allows for more flexibility when testing and deploying if
    proper DNS is not available.

Bug-fixes:

* All roles

  * Fixed how TLS key and certificate material is deployed in order to avoid
    mangling of tabs.
  * Fixed how file modes are specified in tasks to ensure correct permissions
    are applied.
  * Fixed missing ``become`` keyword in tasks that use ``become_user`` for
    consistent execution.

* ``backup_client`` role

  * Fixed configuration (and documentation) for specifying the backup server
    URI - previous implementation included too many forward slashes which could
    cause failures in case of custom SSH server being used for backup.
  * Fixed configuration of additional encryption keys to include all keys listed
    instead of just the first one.
  * Fixed issue with ``backup_server_port`` parameter being completely ignored
    in the configuration.
  * Fixed issue with missing ``/etc/duply/main/include`` configuration file in
    case no backup patterns are deployed.

* ``backup_server`` role

  * Fixed deployment of backup server SSH keys in order to avoid unusable
    ``ed25519`` keys.

* ``common`` role

  * Fixated version of ``pip`` installed for performing Pyhton requirements
    package upgrade checks.
  * Fixed incorrect documentation for parameter ``additional_groups``.
  * Fixed ownership setting for firewall configuration file.
  * Fixed script used for performing checks on pip requirementes files for
    availalbe package upgrades. False positives due to different sorting will
    not be reported anymore, and the script will actually make sure to check if
    upgrades are available (which was not the case before due ot missing
    paramter to pip-compile).

* ``ldap_server`` role

  * Fixed invalid configuration of LDAP server package via
    ``debconf-set-selections`` (wrong option was used for
    ``shared/organization``).
  * Fixed role documentation example for parameter ``ldap_entries`` (was using
    obsolete syntax of ``ldap_entry`` module).
  * When making changes to the LDAP server configuration, make sure to use Unix
    socket. This way the role does not depend on correct LDAP client
    configuration.

* ``mail_server`` role

  * Fixed Postfix main configuraiton file permissions set-up to be explicit.
  * Fixed issue where Postfix server is not restarted when the truststore (used
    for verifying the LDAP server certificate) is changed.
  * Fixed issue with Postfix configuration where the parameter ``mail_user`` was
    ignored when making deliveries to Dovecot (old implementation used fixed
    value of ``vmail`` instead of parameter).

* ``php_website`` role

  * Fixed Nginx configuration file to use correct parameter (``enforce_https``
    instead of ``default_enforce_https``) when configuring HSTS. Previously it
    was possible to set the parameter to ``no``, and still end-up with HSTS
    headers being set-up.

* ``wsgi_website`` role

  * Fixed Nginx configuration file to use correct parameter (``enforce_https``
    instead of ``default_enforce_https``) when configuring HSTS. Previously it
    was possible to set the parameter to ``no``, and still end-up with HSTS
    headers being set-up.

* ``xmpp_server`` role

  * Fixed invalid default value for paramerer ``xmpp_domains`` - it should be a
    list and not a simple string. Previously this would result in invalid domain
    set-up in Prosody configuration file.
  * Fixed issue with permissions not being set on Prosody configuration file,
    making it world-readable (the configuration file contains passwords).


1.5.1
-----

Small bug-fix release for misbehaving package upgrade checks.

Bug-fixes:

* ``common`` role

  * Fixed script used for performing checks on pip requirementes files for
    availalbe package upgrades. False positives due to different sorting will
    not be reported anymore, and the script will actually make sure to check if
    upgrades are available (which was not the case before due ot missing
    paramter to pip-compile).


1.5.0
-----

Minor bug-fixes, package upgrade checks, and better support for next Debian
stable release (Stretch).

New features/improvements:

* ``backup_client`` role

  * Implemented support for next Debian stable release (*Debian Stretch*). This
    was needed due to changes in duplicity parameters and their syntax.

* ``common`` role

  * Added parameter for configuring common backup patterns. Allows for better
    control over ``/root`` and ``/home`` directories. Backup of remaining
    directories is still hard-coded.
  * Added support for checking if package upgrades are available. Covers system
    packages out-of-the-box, and provides ability to perform checks on pip
    requirements files.
  * Added generic support for checking certificate expiration dates. Relevant
    roles need to deploy special configuration files to trigger the checks.

* ``ldap_server`` role

  * Updated role to perform certificate expiration date check on LDAP server
    certificate.

* ``mail_server`` role

  * Updated role to perform certificate expiration date check on all mail server
    certificates.

* ``php_website`` role

  * Updated role to perform certificate expiration date check on website server
    certificate.

* ``xmpp_server`` role

  * Updated role to perform certificate expiration date check on XMPP server
    certificate.

* ``web_server`` role

  * Updated role to perform certificate expiration date check on default web
    server certificate.

* ``wsgi_website`` role

  * Added alternative way to specify Gunicorn version to install in virtual
    environment (via separate parameter). If this parameter is in use, package
    upgrade checks will be done as well (against auto-assembled pip requirements
    file). See role reference documentation for details.
  * Updated role to perform certificate expiration date check on website server
    certificate.

Bug-fixes:

* ``mail_server`` role

  * Fixed incorrect mail name (FQDN) used for mails originating from the server.

* ``web_server`` role

  * Fixed configuration of available TLS versions on the Nginx web server.

Documentation:

* Added release procedures and related information.
* Added information about Debian release compatibility to role reference.

    ``z-index`` value.

* ``wsgi_website`` role

  * Make sure the environment indicator is always shown on top by increasing its
    ``z-index`` value.


1.1.0
-----

Minor bug fixes, enchancements, and features.

New features/improvements:

* ``common`` role

  * Added support for having user-defined ``/etc/profile.d`` style scripts (in
    ``~/.profile.d/``.
  * Disables Emacs ``electric-indent-mode`` globally if Emacs is installed.
  * Deploys symbolic link for ``mysql_config`` if package
    ``libmariadb-client-lgpl-dev-compat`` is installed (workaround for
    `Debian Bug 766996
    <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766996>`_)
  * Updates CA cache immediatelly so that roles depending on cache being
    up-to-date do not throw validation errors.

* ``mail_server`` role

  * Added support for specifying local aliases.
  * Undeliverable bounces are now delivered to postmaster.

* ``php_website`` role

  * Added support for specifying custom ``php-fpm`` pool configuration options.
  * Added support for having ribon/strip at bottom to identify website
    environment. Useful for testing/staging environments.
  * Deploys symbolic link for ``mysql_config`` if package
    ``libmariadb-client-lgpl-dev-compat`` is installed (workaround for
    `Debian Bug 766996
    <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766996>`_)
  * Forwards mails delivered to application or application administrator users
    to local ``root`` account (can be configured to deliver mails elsewhere).
  * Sets ``HSTS`` policy if TLS is enforced.
  * *Umask* for the operating system which runs the website is set to ``0007``.
  * When administrator user is created for the first time, its home directory is
    populated from ``/etc/skel``. This makes prompts etc look more uniform
    across the system.

* ``wsgi_website`` role

  * Added support for having ribon/strip at bottom to identify website
    environment. Useful for testing/staging environments.
  * Added support for specifying environment variables that should be set when
    running the service, or when administering the installation (using
    application administrator operating system user).
  * Deploys symbolic link for ``mysql_config`` if package
    ``libmariadb-client-lgpl-dev-compat`` is installed (workaround for
    `Debian Bug 766996
    <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766996>`_)
  * Forwards mails delivered to application or application administrator users
    to local ``root`` account (can be configured to deliver mails elsewhere).
  * Sets ``HSTS`` policy if TLS is enforced.
  * *Umask* for the operating system which runs the website is set to ``0007``.
  * When administrator user is created for the first time, its home directory is
    populated from ``/etc/skel``. This makes prompts etc look more uniform
    across the system.

Bug-fixes:

* ``database_server`` role

  * Applies UTF-8 configuration immediatelly. This should fix issues during
    inital server set-up for roles that need to create database using UTF-8
    character set.

* ``wsgi_website`` role

  * Fixed virtualenv wrapper shell script to use proper escaping around
    arguments.
  * Website service is now restarted in case of package changes (system or
    virtual environment).

* ``mail_forwarder`` role

  * Allows incoming SMTP connections from the SMTP relay server (if
    configured). This way the SMTP relay can deliver bounces.


1.0.1
-----

Minimal bugfix update to improve interoperability.

Changes:

* ``xmpp_server`` role no longer restricts TLS to version 1.2 and ciphers to PFS
  ciphers. Should solve ``s2s`` communication issues with old XMPP servers.


1.0.0
-----

Initial release of Majic Ansible Roles.

New roles:

* ``backup``, reusable role for specifying files to back-up.
* ``backup_client``, base role for setting-up backup client on a server
  (Duplicity).
* ``backup_server``, sets-up a backup server.
