Release notes

=============

7.0.0

-----

Dropped support for Debian 9 (Stretch), moved away from using

non-Debian project repositories (like Prosody ones).

**Breaking changes:**

* All roles

  * Dropped support for Debian 9 (Stretch).

* ``xmpp_server`` role

  * Parameter ``xmpp_prosody_package`` has been dropped.

**New features/improvements**

* ``common`` role

  * Added parameters ``pip_check_requirements_in`` and

    ``pip_check_requirements_py3_in`` that can be used for specifying

    input requirements when checking for available package upgrades

    for Python virtual environments that are used for the checks

    themselves. This is particularly helpful in cases where Python

    version gets deprecated and some packages do not correctly declare

    the minimum version required, allowing to be more specific to

    avoid unnecessary warning mails being sent out.

  * Updated default package pins for virtual environments used to

    check for available pip package upgrades.

* ``mail_server`` role

  * Added parameter ``mail_server_smtp_additional_configuration`` that

    provides ability to include additional configuration directives

    for the SMTP server.

* ``xmpp_server`` role

  * Drop dependency on the external (Prosody) package

    repository. Install everything using official Debian

    repositories. This should help avoid future issues with Prosody

    project removing older versions of packages or dropping entire

    repository archives for older Debian releases.

  * Prosody package and some of its dependencies are installed from

    Debian backports to get more featureful release installed.

  * Role no longer depends on fetching external Prosody modules from

    project code repository, and instead relies on the prosody-modules

    package for LDAP authentication module.

6.0.0

-----

Added support for Debian 10 (Buster), alongside a couple of minor

changes and features/improvements.

**Breaking changes:**

* ``ldap_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 LDAP server. This change

    is applicable only under Debian Buster.

**New features/improvements:**

* All roles

  * Added support for Debian 10 (Buster).

* ``common`` role

  * Added parameters ``maintenance`` and ``maintenance_allowed_hosts``

    for enabling maintenance mode. In maintenance mode only the listed

    hosts are allowed to connect to the server.

**Bug fixes:**

* ``ldap_server`` role

  * Allow use of DHE TLS ciphers by generating the necessary

    Diffie-Hellman parameters. This bug fix is applicable only under

    Debian Buster.

* ``wsgi_website_`` role

  * When the virtual environment is created, the ``setuptools`` and

    ``pip`` packages will not get pinned to any specific version,

    allowing roles that are based on ``wsgi_website`` to easily

    install preferred versions, and avoid idempotence problems in the

    process.

5.0.0

-----

Upgrade to Ansible 2.9.x, dropping support for Debian 8 Jessie,

upgrade to Python 3.x, dropping support for Python 2.7. A number of

parameters have been made mandatory or deprecated. Security has been

slightly improved in a number of roles, and there is plenty of

bug-fixes and minor improvements throughout as well.

**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.

* ``database_server`` role

  * Parameter ``db_root_password`` has been deprecated. The root user

    can now login into the database (as the root database user) via

    unix socket authentication.

  * Role will drop the use of Debian system maintenance user

    (``debian-sys-maint``) in favour of using the root account with

    UNIX socket authentication if the database server has not already

    been set-up in that manner. This is the default behaviour starting

    from Debian Stretch, and the ``debian-sys-main`` will be present

    only if the server has been upgraded from older releases.

* ``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.

  * Dropped the use of ``procmail`` for local mail deliveries.

* ``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.

* ``mail_server`` role

  * Fixed the problem with the SMTP server (Postfix) not using TLS at

    all for outgoing SMTP connections. The server will now default to

    using opportunistic TLS (using TLS where available).

* ``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 configuration has been slightly updated to better

    match what is currently the defaults in Debian Stretch.

* ``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.

  * Mail server configuration has been slightly updated to better

    match what is currently the defaults in Debian Stretch.

* ``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.
