Kopano Core 8.7.1 Final (8.7.1.0)

Released: 2019-05-02

The 8.7.0 release of Kopano Groupware Code did suffer from a range of caching issues with one of these resulting in messages being displayed as unread after the server has been restarted (or caches have been cleared). If users on the installation are affected by this run the following command (after upgrading to 8.7.1) to correct this display issue:

kopano-dbadm kc-1444

The command can safely be executed while kopano-server is running. If you run the command while kopano-server is running, make sure to also run kopano-admin --clear-cache=0x0020 to clear the cell cache so the changes can be re-read from the database.

Known issues:

  • no packages for RHEL 6 -> these will return with 8.7.2

Kopano Core 8.7.0 Final (8.7.0.0)

Released: 2019-01-24

Kopano Groupware Core 8.7 is the first release to include a range of new components for the Kopano platform. These new components include support for OpenID Connect and initial support for our new RestAPI. Apart from this version 8.7 also brings performance and security improvements.

Kopano Groupware Core provides the Groupware functionality of the Kopano stack and in most cases sits at the heart of every Kopano environment. It is therefore a key figure in our promise to deliver stability and extensibility of Kopano’s proven communication platform. Kopano Archiver consists of additional archiving components, allowing Kopano Groupware servers to run on dedicated, and sometimes slower, storage servers for archived messages, while keeping the items available to the user.

New components in Kopano Groupware Core 8.7

Kopano 8.7 introduces two new components, which will play an important role in future client development and the integration of Kopano with external applications and platforms. The first new component that I want to introduce is Kopano Konnect. Konnect is an OpenID provider (OP) that directly integrates a web login with a consent form. It brings support for both OpenID Connect (OIDC) and Open Authentication (OAuth 2.0). Through this tool administrators can easily allow their users to login at third party applications, such as Owncloud and Nextcloud with the “Social Login” plugin, Wordpress, OpenProject and many more. In addition to the easier integration with third-party applications, Kopano Konnect will also provide the authentication for the Kopano RestAPI and clients consuming it.

Want to learn more about Konnect? In the past we already gave a short introduction into Kopano Konnect. There are two main changes since the release blog post: you can now install Konnect through distribution packages and you no longer need to rely on Docker or binary downloads. Are you running Kopano on Univention Corporate Server and want to give Konnect a try? Kopano Konnect is available as Open ID provider with added Univention branding and integration on UCS.

Another new component is our new RestAPI “Kopano API” (or KAPI for short). KAPI is modelled after the Microsoft Graph RestAPI and will make it easier than ever before to integrate your Kopano data with external applications and clients. App developers should make sure to check our Compat documentation for further information on Graph and where we differ in our implementation. The first new client that will make use of KAPI is the Kopano Meet. We will have another blog on this subject in the beginning of 2019.

The Kopano RestAPI is only available for Debian 9, Ubuntu 16.04 and Ubuntu 18.04 at the moment. The API backend is made in Python3 and other distributions (RHEL, SLES, Debian 8) either do not have all dependencies in their repositories or not a recent enough version of Python. Support for SLES and RHEL will be added later on. The usage of Kopano WebApp or Z-Push is not affected by this.

Improved performance and security

Where available services now prefer python3 instead of python2.

Support for 4-Byte UTF-8 Unicode Encoding (utf8mb4)

Kopano now includes support for unicode characters outside of the actual body of an email (in the subject for example). To support such characters the database needs to be modified to support the utf8mb4 character set. New installation create the tables already in the correct encoding, but existing databases need to be upgraded by running kopano-dbadm usmp (while kopano-server is not running).

Until the above command is run kopano-server will continue to work as in previous versions (unicode emoji will not be shown reliably).

Reporting of usage statistics

Starting with Kopano Groupware Core 8.7 the server process contains a new stats gathering and reporting functionality that is sending basic usage statistics back to us at Kopano. The transmitted statistics include:

  • a unique machine ID
  • the name of the submitting service
  • the version of the submitting program
  • an internal Kopano server GUID
  • an OS identifier
  • an identifier for the Kernel and architecture used
  • the configured Kopano user plugin
  • the number of active users
  • the number of contacts created
  • the number of inactive users (split in users, equipment and rooms)

Internally we are also enhancing these stats with a timestamp when the system sends a report for the first time and another timestamp tracking when the the system contacted us last.

Below is an example of how we store such a report internally:

+------------------------------------------------------------------+------------------------------------------------------------------+------------------------------------------------------------------+---------------------+---------------------+----------------+-----------------+-------------------+-----------------+-------------------+------------+------------------------------+--------------------------------------------+---------------+-----------------+-------+

+------------------------------------------------------------------+------------------------------------------------------------------+------------------------------------------------------------------+---------------------+---------------------+----------------+-----------------+-------------------+-----------------+-------------------+------------+------------------------------+--------------------------------------------+---------------+-----------------+-------+

We hope to learn a bit more about our user base from these reports.

How to turn the survey reporting off?

The following configuration options in server.cfg have an influence over the report sending:

  • surveyclient_url
  • surveyclient_interval
  • surveyclient_ssl_verify

To disable sending of reports it is sufficient to include the line surveyclient_interval=0 in your server.cfg

Important configuration changes

Some configuration options have changed compared to Kopano 8.6 or an earlier version. Below you will find a list of deprecated options and their replacements.

server.cfg

The following options are deprecated: - server_ssl_enabled - server_ssl_port - server_tcp_enabled - server_tcp_port

The above options have been replaced with (these options were already available in Kopano Groupware Core 8.6.x): - server_listen - server_listen_tls

ical.cfg

The following options are deprecated: - ical_enable - icals_enable - ical_port - icals_port

The above options have been replaced with: - ical_listen - icals_listen

gateway.cfg

The following options are deprecated: - imap_enable - imaps_enable - imap_port - imaps_port - pop3_enable - pop3s_enable - pop3_port - pop3s_port

The above options have been replaced with: - pop3_listen - pop3s_listen - imap_listen - imaps_listen

Upcoming changes in Kopano 9.0

For the Kopano 9.0 release we are already planning some more changes, which we have announced in the “Housekeeping” blogpost. These changes can be summarised as:

  • switching to PHP 7.x compatibility only
  • switching to Python 3 compatibility only

These changes will result in changed set of supported distributions from the release of Kopano Core 9.0 and onwards. More details can be found in the blog post.

But there are also some smaller under the hood changes, that will only matter for custom integrations.

For backwards compatibility we still provided a python-zarafa module within python-kopano. We plan to remove the compatibility bridge for Kopano Groupware Core 9.0. Additionally this release will also be the last release that to ship php class files. These files were already redundant, since both Kopano WebApp and Z-Push were shipping their own versions for quite a while. With the removal of the php version of kopano-mr-accept and kopano-mr-process in 8.7, these files are now no longer needed and will therefore be removed in the 9.0 release.

What to look out for when upgrading?

This version introduces updates to the internal schema. Before upgrading to this version make sure that the steps explained in https://kb.kopano.io/display/WIKI/K-1216 have been executed or plan in additional time to execute these after the upgrade. kopano-server will print upon restart if kopano-dbadm k-1216 still needs to be run. Another indicator would be the absense of the current running version in the versions MySQL table.

It has been observed that the script for creating store cannot be found after upgrade: https://jira.kopano.io/browse/KC-1339 The simple fix for this would be to uncomment the values for the userscripts so the built in defaults are used. This is explained in more detail in above ticket.

The kopano-search rpm now has a dependency on poppler-utils, which pulls in some additional packages: https://jira.kopano.io/browse/KC-1245

When upgrading from our repositories on UCS you will notice that because of the above mentioned configuration file changes kopano-gateway and kopano-ical will refuse to start. The integration package already provided an upgrade script for this case within the 8.6.8 upgrade, which can be found at /usr/share/kopano4ucs/kopano4ucs-update-settings870.sh.

As always make sure to have a backup of your running system and configuration before upgrading.

Kopano Groupware Core 8.6

With the 8.5 release cycle of Kopano Groupware Core we started a new initiative to get into smaller and more frequent releases for Kopano Groupware Core. The 8.6 release will now be the first release to benefit from this.

Starting with 8.6.1.81 we have stopped installing /etc/default/kopano (for Debian based distributions) and /etc/sysconfig/kopano (for rpm based distributions).

Important: Kopano 8.6 will be the last Kopano Groupware Core release with packages for Ubuntu 14.04. We recommend to upgrade to either 16.04 or 18.04.

Kopano Core 8.6.8 (8.6.8.0)

Released: 2018-10-05

This release changes the way the language is specified for store creation. Instead of configuring these within ´´/etc/default/kopano´´ or /etc/sysconfig/kopano they are now set by specifying default_store_locale within /etc/kopano/admin.cfg. Please consult the language chapter in the admin manual for more details.

Kopano Groupware Core 8.5

Kopano Groupware Core has been overhauled in a way that its now capable of running mostly “without configuration files” as a result of this you might see your current configuration renamed to *.rpmsave or *.dpkg-old files. If this is the case simply rename it back and restart all services.

This move away from configuration files also revealed a mismatch in the default value in our configurations files, with the default value of the individual services, which is already fixed for the next release. While in the configuration files we still define /var/log/kopano/$servicename.log as the default log location, all services actually default to - (standard output) (as introduced in KC-745). This means that systems running systemd/journald will find logging by default in these services.

Known Issues:

  • currently all Kopano services are not restarted in Debian based distributions. We are looking into a fix as part of ticket KC-1061. Until this is resolved services needs to be restarted manually after an upgrade. Alternatively the package needrestart could be installed.

Kopano Core 8.5.7 (8.5.7.0_0+22)

This new release of Kopano Core which contains a resolution for two vulnerabilities. Updating requires some extra attention. As the update is not a regular one, it can require some extra steps to upgrade your installation from any previous version to this new release.

ABOUT THE ISSUES

The issues were discovered while investigating a report by a customer that a server became slower after an upgrade. Our developers discovered that the issue was caused by an unexpectedly large number of items in one of the database tables (the ‘names’ table). Further investigation made clear that this is a vulnerability which in some cases has a small chance to cause a corruption or data loss in the Kopano Server database. These vulnerabilities have been identified in all previous versions of the software, going back even before the 8.0 release (pre-Kopano).

Aside from the fixing of the issue in question, the discovery led to the registration of vulnerability identifiers. The vulnerabilities have been identified as CVE-2018-8950 and CVE-2018-8951. Note that these vulnerabilities have not yet been published - but will be soon after the release of the version that contains the fix.

APPLYING THE FIX

This new release resolves the issue in the code, but it also requires a database schema change. In some cases, this database schema cannot be applied because the Kopano Server has found unexpected entries in the names table. This needs to be resolved with the new kopano-dbadm utility (built specifically to resolve this issue). We strongly recommend you to create a dump of the database before applying the fix (sqldump).

Applying the fix with kopano-dbadm can take some time in larger environments. However, you can also ‘ignore’ the schema upgrade by starting the Kopano Server with a special flag. If you choose to do so, we recommend planning to run the script to fix the issue as soon as possible in order to prevent future corruption of data.

More information about upgrading can be obtained from our blog and the Knowledge Base.

Kopano Core 8.5.6 (unreleased)

This minor release features further improvments to kopano-spamd (which was introduced with 8.5.0, but not yet fully packaged) the daemon now has a configurable run_as_user and run_as_group. When using kopano-spamd make sure that the provided user is both part of the amavis group, as well as local_admin_user within Kopano.

Apart from that this update also includes a fix for KC-1074, which shares the same cause as KC-1068. Every newly created item will now again show up in the “To-Do List” folder in WebApp and succesfully create a reminder in WebApp. For item created while running any of the previous 8.5.x builds its recommended to once start kopano-server with the --restart-searches once.
