OpenVPN 3 Linux v23 (Stable release)

The v23 release is stable release which expands the distribution target
since v22_dev was released.  The goal for this step was to stabilize the
codebase which was migrated to GDBus++ and the new Meson building system.

This release brings back the OpenVPN 3 AWS-VPC Add-on which was not
ready for the v22_dev release.  This service has also been migrated to
use GDBus++.  The behaviour of this add-on should otherwise be identical
to the service shipped in v21 and older releases.

In addition, a new add-on is included in this release.  The Cloud Connexa
service is being extended with a new functionality, referred to as Device
Posture Checks (DPC).  This feature will enable the VPN server to request
certain checks to be performed on the client side and reported back to
the server.  These checks are restricted to what the new OpenVPN 3 Device
Posture Service (openvpn3-service-devposture) provides.  To enable the
client-side functionality, the VPN client configuration must be pre-
imported and an Enterprise ID must be assigned to the configuration
profile.  That will allow the server to request Device Posture Checks
to be performed.

The currently implemented DPC tests only provides platform information,
like Linux distribution name and version, kernel versions, CPU
architecture and the client's local time.  In future releases, more tests
may be implemented.

Known issues:

  - Shell completion may list duplicated options in some cases

  - openvpn3-admin journal --since has a time zone related issue
    and may not list all log events within the closest hours.

Other changes:

* Improvement: Upgrade to OpenVPN 3 Core Library v3.10.1

  This library update provides the functionality to provide the
  Device Posture Check functionality in the OpenVPN wire
  protocol.  A fix to resolve compilation errors when the
  -Wnon-virtual-dtor compiler flag is enabled is included too.

* Bugfix: Report client and version correctly in IV_GUI_VER

  The v22_dev release unfortunately changed the format of the
  IV_GUI_VER.  It would report: 'openvpn3-linux/v22:dev' when
  it should have been 'OpenVPN3/Linux/v22_dev'.  This has
  been corrected.

* Bugfix: --tag option not working with config-import or config-manage

  A regression bug was introduced in v22_dev which handled the
  available tracking of Configuration Manager features incorrectly
  and ended up disabling this feature in the openvpn3 config-import
  and openvpn3 config-manage commands.  This has been fixed.

* Bugfix: systemd-resolved support rejected IPv6 DNS resolver address

  An oversight in the systemd-resolved implementation refused to accept
  pushed DNS resolver addresses when it was an IPv6 address.  This has
  been fixed and both IPv4 and IPv6 addresses are now fully supported.

* Improvement: Python configuration parser support for --connect-retry{,-max}

  The Python configuration parser in the openvpn3 module did
  not provide a pass-through for --connect-retry and --connect-retry-max
  options.  This would result in configuration profiles containing
  these options would not function when using the Python based tools
  while it would work using the 'openvpn3' command.

Thanks goes to those continuing testing and reporting issues.  A
special thanks to Grzegorz Gutowski who provided the fix to the
Python module.  He is also the project lead behind the openvpn3-indicator
project, which provides a tray-icon for OpenVPN 3 Linux.  If you
use a graphical desktop, that's a project worth checking out!

Many thanks also goes to Razvan Cojocaru who has stepped in providing
many great improvements and done all the work for the Device Posture
support in OpenVPN 3 Linux.  And Lev Stipakov who migrated the
OpenVPN 3 AWS-VPC add-on service to GDBus++

OpenVPN 3 Linux v22_dev (Limited Release)

This is a limited release primarily targeting Fedora 39 and newer plus
Ubuntu 24.04.  Other Linux distributions shipping glib2 version 2.76
or newer will also benefit from this release.

This release contains a massive re-factoring of the D-Bus integration
layer with glib2.  The glib2 2.76 and newer releases contains several
internal changes which broke the D-Bus implementation layer in
OpenVPN 3 Linux v21 and older releases [1]. To fix this, it was decided
to split out the base D-Bus integration into a new standalone library
which OpenVPN 3 Linux will depend on.  This new project is called
GDBus++.

[1] <https://github.com/OpenVPN/openvpn3-linux/issues/171>

This change brings in a vastly improved D-Bus integration which will
now make extended use of multi-threading when processing D-Bus method
calls and implements modern C++17 approaches when handling requests to
registered D-Bus objects.  It has also been a strong focus on getting
rid of as much of various glib2 warnings which could occasionally appear
in prior OpenVPN 3 Linux releases.

There are most likely a still a lot more room for improvements to both
the new DBus++ and the upgraded OpenVPN 3 Linux code, which is why this
release targets a more limited release scope.

That said, this new code can be made available for all the officially
supported RPM distributions by enabling a "development snapshots" repository.
But this repository will also not have the same QA guarantees as the
official stable repositories.

This release has only been through the full QA validation on Fedora 39,
Fedora 40 and Ubuntu 24.04.

On a development note, this project has now migrated to use Meson [2] as
the build system.  The autoconf/automake build system is now completely
removed.  The Meson build system has turned out to be way simpler to
use and configure than autotools ever was, especially from a developers
point of view.

[2] <https://mesonbuild.com/>

There are unfortunately a few known issues which is targeted for
the coming v23 release:

  - AWS VPC integration is not yet ready, so this add-on is currently
    not available in this v22_dev release.

  - Shell completion may list duplicated options in some cases

  - openvpn3-admin journal --since has a time zone related issue
    and may not list all log events within the closest hours.

Other changes worth mentioning with this release:

* Improvement: Upgrade to OpenVPN 3 Core library v3.8.5

  This upgrade contains several bug fixes related to the option
  parser, mostly issues reported by a wide range of users.  In
  addition to incorrect behaviour with the stub compression when
  the --compress option was used.

* Improvement: openvpn3-admin journal --since argument

  The --since argument can now use the keywords 'today' and
  'yesterday'.

* Bug fix: openvpn3-admin log-service would not change some settings

  On some distributions, the --dbus-details and other boolean flags
  was not properly changed when requested.  This has been improved.

Finally, it is needed to give a HUGE THANK YOU to all the community
testers which installed and tested rolling development snapshots during
the development of this release.  Without all this testing, we would
not have the same confidence in this release as we have now.  All your
help and feedback has been really valuable and helpful during this the
development phase.

OpenVPN 3 Linux v21 (stable)

This is primarily a maintenance release with several minor bug fixes
and general improvements.

* Improvement: Upgrade OpenVPN 3 Core Library to v3.8.2

  This is an upgrade from Core Library 3.7, which provides more
  enhancements and adds support for the newer ovpn-dco-v2 kernel module

* Bugfix: OpenVPN 3 Linux AWS VPC lacks support for IMDSv2

  mattjbyrd reported the AWS VPC integration was not working with EC2
  instances where IMDSv2 was enforced.  This issue is resolved with
  the OpenVPN 3 Core Library upgrade.

  Details: <https://github.com/OpenVPN/openvpn3-linux/issues/192>

* Bugfix: Python StatusCallback did not work without LogCallback enabled

  Jeremy Fleischman reported an issue related the openvpn3 Python
  module did not work when just setting up a
  SessionManager.StatusCallback() method.  He provided a fix which is
  now included in v21.  Thanks a lot, Jeremy!

  Details: <https://github.com/OpenVPN/openvpn3-linux/commit/ba6fe37e7e28d1e633b56052383da3072f03c11e>

* Bugfix: openvpn3 config-manage override may not always work

  The openvpn3 config-manage override options would in some cases not work
  due to a programming error related to an internal set_override() method
  and the SetOverride() D-Bus method.  The result was that typically
  string values ended up empty.  Now all the overrides can be configured
  again.

* Bugfix: OpenVPN 3 Python based configuration parser issues

  Several options and --profile-overrides did not work or was completely
  missing, like the dns-scope and allow-compression overrides.  This
  has been improved and the list of overrides should now be up-to-date
  with openvpn3 config-manage.

  The Python based option parser also did not fully support overrides
  with a boolean true/false setting properly.  This has also been
  fixed.

* Improvement: Detect needed host specific settings during package install

  The OpenVPN 3 Linux v20 introduced the openvpn3-admin init-config
  command.  This has been further improved and will now be run
  automatically during the package installation.  This command will
  probe the system for important features on the system, like what
  kind of system logging is in use, what kind of DNS resolver
  approach being available (systemd-resolved, /etc/resolv.conf) as
  well as doing other sanity checks, like if the needed openvpn
  user/group is present, important directories being configured
  correctly and that SELinux based systems have the proper file
  contexts set up.

  The default behaviour is that existing configuration changes done
  will NOT be overwritten.  But if no settings has been set, it will
  generate configurations files better matching the running system.

* Improvements: OpenVPN 3 Log Service

  The OpenVPN 3 Log service (openvpn3-service-logger) made it
  hard to track where Attached: and Detached: log events came
  from.  This does now add a PID reference, which can be traced
  more easily in the logs.

* Improvements: OpenVPN 3 Configuration Manager feature support tracking

  When upgrading OpenVPN 3 Linux versions, there might be situations
  where an older OpenVPN 3 Configuration Manager will be running but
  the openvpn3 command line tool is newer.  When the command line tool
  attempts to access features in the Configuration Manager backed not
  available, it would result in an error and a poorer user experience.

  The code providing the glue interface for the calling side (openvpn3)
  has been extended with a feature/version mapping, so it can filter out
  operations not supported if the backend version is lacking certain
  functions.  In most cases, the openvpn3 config commands will then
  continue to work as before, just not providing access to features
  available in newer back-ends.

  A similar functionality is planned for the Session Manager and is
  being considered for the OpenVPN 3 Python module.

* Improvements: OpenVPN 3 Python module

  Configuration profiles from OpenVPN Access Server and
  some times OpenVPN Cloud Connexa will often contain "meta options",
  typically prefixed with "# OVPN_".  The Python parser would
  not accept several of the deprecated meta options.  The
  parser has now been extended to filter out those options not
  needed, used or supported by the OpenVPN 3 Core Library.

* Improvements: Adjustments needed to satisfy Debian packaging

  Several minor issues has been done to satisfy the Debian package linter
  utility.  There are still some issues left, some will not be possible
  to improve before Debian ships with a newer dbus-daemon - as we need
  functionality present in a newer release.  The dbus-broker is also
  lacking a similar functionality currently.

  This work is also done in collaboration with Marc Leeman who is
  working on providing an native Debian repo package for OpenVPN 3 Linux.
  Thanks a lot, Marc!

  Details: <https://github.com/OpenVPN/openvpn3-linux/issues/193>

* Feature: Label/tag support for imported OpenVPN configuration profiles

  The OpenVPN 3 Configuration Manager and the openvpn3 config-manage and
  configs-list commands has been extended to with the ability to add one
  or more text labels to configuration profiles.  At import time, the
  openvpn3 config-import command can also assign tags immediately.

  Users with many imported configuration profiles can more easily filter
  which configurations shown with the openvpn3 configs-list command.
  Other tools (openvpn3-as, openvpn-connector-setup) will also make use
  of this feature as they are being updated, to more easily understand
  where a configuration profile arrived from.

* Feature: JSON formatted output with openvpn3 configs-list and config-dump

  The list of configurations can now be retrieved as a JSON formatted
  list via the openvpn3 configs-lists.

  The openvpn3 config-dump will normally dump the normal configuration
  using the standard OpenVPN configuration file format.  The JSON format
  will contain all the additional meta options, overrides and access
  control lists not expressed in the standard file format.  This format
  is the same format used internally for persistent configuration
  profiles.

* Feature: Filtering options when retrieving available configurations

  The openvpn3 configs-list command has been extended with several
  filter arguments to only extract filters with a specific tag or
  owner as well as a simple prefix filter on the configuration name.

  The OpenVPN 3 Configuration Manager also exposes two new D-Bus
  methods to retrieve available configuration profiles based on a
  tag or owner.

* Feature: Simple and verbose list formats in openvpn3 configs-list

  The default listing in openvpn3 configs-list has been simplified
  and will only list one configuration profile per line now.  The
  more comprehensive list can be retrieved using the --verbose
  argument.  The verbose list will also include configuration tags.

OpenVPN 3 Linux v20 (stable)

This is the first stable relase of OpenVPN 3 Linux.  This release is
mostly adding minor improvements, a few bug fix and adding two more
helper tools.

* Feature: openvpn3-admin journal

  This is a helper function to retrieve log events from the OpenVPN 3 Linux
  stack logging with systemd-journald.  It can be considered a lightweight
  journaldctl tool, which is targetting some of the filters useful for
  OpenVPN 3 Linux.

* Feature: openvpn3-admin init-setup

  This is another helper function to configure OpenVPN 3 Linux in an
  automated fashion based on the current runtime environment.  It will
  ensure proper   state directories are present with the proper ownership
  and access, as well as SELinux context lables if that is availale.  It
  will check if the needed user/group accounts is present and wether to
  use systemd-journald and systemd-resolved or not.

  In the next release, this feature will be used in the the packaging
  scripts for Debian/Ubuntu and Fedora/Red Hat Enterise Linux packaging
  as well.

* Improvement: Full support for CR_TEXT based multi-factor authentication

  Prior releases did not fully support CR_TEXT/crtext based authentication
  which would result in disconnecting from the server while querying the
  user for the additional credentials.  This new mode is more efficient and
  will keep the connection to the server alive.

* Improvement: Improve behaviour with incorrect private key passphrase

  Prior releases would dump an error message which would not be much
  end-user friendly if the connection failed due to incorrect passphrase
  to the private encryption key needed for the connection.  This has
  been improved and the error handling should be more clear for
  non-technical users.

* Improvement: Run resume and restart operations in the background

  Until now, the openvpn3 session-manage --resume and --restart operations
  would run in the foreground, resulting in stopping the VPN session if
  this operation would be interrupted.  These operations can typically run
  in the background.  If a re-authentication would be need, the
  openvpn3 session-auth command is available to complete that operation.

  It is also possible to run these operations in the foreground by
  adding the --timeout argument with a value reasonable to wait for this
  operation to complete.

* Improvement: Install openvpn3/constants.h header file

  This adds ah eader file which contains all the constants used by the
  OpenVPN 3 Linux stack, which is suitable for C programs.  The constants
  listed here is similar to the constants found when importing the
  Python 3 openvpn3.constants module.  These constants are typically used
  in D-Bus signals issued by the OpenVPN 3 Linux stack.

* Bugfix: Don't hardcode use of  --journald in openvpn3-service-logger

  Not all Linux distributions ships with the systemd stack.  Auto-detect
  during build time if systemd support is available or not and fallback to
  syslog if systemd support is lacking.

* Bugfix: Don't hardfail if systemd-resolved is unreachable

  If openvpn3-service-netcfg could not reach or access the systemd-resolved
  service, it would hard-fail which again would cause the VPN session to
  fail starting.  This has been changed so the VPN session will succeed,
  but it will instead not do the DNS configuration.  This situation will be
  duely logged in the system logs.

* Documentation: Highlight deprecation of openvpn3-autoload

  The openvpn3-autoload feature is being deprecated in favour of using the
  systemd openvpn3-session@.service feature instead.  The openvpn3-autoload
  feature will still be around though, until there is a suitable alternative
  for Linux distributions not capable of using the more native systemd
  approach.

* Documentation: Generic overhaul

  Lots of the man pages as well as README.md file has been reviewed and
  updated.  Lots of details has been clarified and the README.md has been
  split up into several files as it has grown quite a lot and some of the
  information would be better to have in other files to avoid duplicating
  the information.

* Code: Coding style

  There exists now a .clang-format coding style definition and all the
  C++ source code and headers should now be using this style.

* Copyright: Switch to SPDX license tags

  To ease the maintenance of copyright blobs, all files with an AGPL
  copyright blob has been switched to the SPDX license tag.

OpenVPN 3 Linux v19 (beta)

This release does another round of improving the logging system,
in addition to bug fixes and other improvements.

* Log system changes

  The net.openvpn.v3.log service has been extended to support logging
  directly to systemd-journald as an alternative to syslog.  The
  default log destination has been changed from syslog to journald.

  Using the systemd-journald as the log destination allows attaching
  more meta data variables to the log events, which can be used when
  querying the journal using journalctl.  These additional meta data
  variables can be observed when using the 'verbose', 'json',
  'json-pretty' or 'export' output modes (journalctl --output)

  The OpenVPN 3 Linux specific meta data variables are prefixed with
  "O3_".  The meta variables OpenVPN 3 Linux may make use of are:

  - O3_LOG_GROUP / O3_LOG_CATEGORY
    These are direct mapped to the logging classification described
    here: <https://github.com/OpenVPN/openvpn3-linux/blob/master/docs/dbus/dbus-logging.md>

  - O3_LOGTAG
    This tag is unique per openvpn3-service-* process and will be
    changed if the process restarts.  This information has so far
    been added to the beginning of the log lines, as the '{tag:....}'
    prefix.  This prefixing to the log lines can now be removed by
    running:

        # openvpn3-admin log-service --enable-log-prefix false

    The O3_LOGTAG will have the same content as the prefix, without
    the '{tag:...}' encapsulation; O3_LOGTAG contains only the plain
    identifier.  The log tags currently active can be listed by
    running:

        # openvpn3-admin log-service --list-subscriptions

  - O3_SENDER, O3_INTERFACE, O3_OBJECT_PATH
    These are added if the D-Bus log details are enabled by running:

        # openvpn3-admin log-service --dbus-details true

  - O3_SESSION_TOKEN
    This is used by the openvpn3-service-client process, where the
    session token has the same value as the argument the process
    is started with

  To list only these OpenVPN 3 Linux meta variables, run this
  command:

     # journalctl -o verbose --since today \
          --output-fields=O3_SENDER,O3_INTERFACE,O3_METHOD,O3_OBJECT_PATH,O3_LOGTAG,O3_SESSION_TOKEN,O3_LOG_GROUP,O3_LOG_CATEGORY,MESSAGE \
           _PID=$(pidof openvpn3-service-logger)

  This query can be extended further to narrow down the log scope.
  To only list client process log events, add this to the line
  above:  O3_LOG_GROUP=Client

* Enhancement: IV_PLAT_VER sent to server
  This field provides OS details of the platform the OpenVPN 3 client
  is running on.  This will contain an arbitrary string provided by
  either the systemd-hostnamed service, or if that is unavailable it
  will extract some more generic information using the uname()
  system function.

  The IV_GUI_VER string has also been slimmed down a bit to only
  provide information about the OpenVPN 3 Linux client alone.  The
  IV_VER will contain information about the OpenVPN 3 Core library
  version which OpenVPN 3 Linux is compiled against.

* Update to OpenVPN 3 Core Library v3.7.1
  This update of the OpenVPN 3 Core library is a maintenance release.
  The changes which touches OpenVPN 3 Linux is related to the ovpn-dco
  kernel module support.  On systems running more VPN sessions in
  parallel with DCO (Data Channel Offload) enabled, the Core library
  could in some situations perform operations on the wrong DCO
  interface.

* Bugfix: Web based authentication with OpenVPN Access Server fix
  When connecting to OpenVPN Access Server configured with web based
  authentication (i.e. SAML), the authentication could fail on
  renegotiations.  The fix currently applied will require to import
  the Access Server profile once again.  This will be improved
  further in the next release.

* Bugfix: Python warning with openvpn3-as on Ubuntu 22.04
  When running the openvpn3-as utility on Ubuntu 22.04 it would complain
  about using a deprecated ssl.SSLContext() mode.  This has
  been updated to use the preferred mode.

* Bugfix: openvpn3 command line bash-completion
  The bash-completion support has been changed to avoid adding an
  additional space after file and directory names.

OpenVPN 3 Linux v18 (beta)

This release does a larger overhaul on the logging system with a few
additional bug fixes and other improvements.

* Log system changes

  In prior releases, the backend VPN client (openvpn3-service-client
  processes) sent Log signals (events) to the log service
  (openvpn3-service-logger process).  If a user wanted to receive
  real-time log events, it could easily do so by flipping a boolean
  flag in the VPN session, managed by the session manager
  (openvpn3-service-sessionmgr process).  In this case, the session
  manager would also pick up Log events from the VPN client and
  forward them.

  This architecture had a flaw which meant that if the log forwarding
  in the session manager was enabled for a session, anyone could pick
  up these log events.  And if one of these log listeners turned off
  the log forwarding, this would happen for all other listeners at
  once.  This design also meant that the VPN client process needed to
  send Log events to two different destinations; both the logger and
  the session manager.

  With the change introduced in v18_beta, the VPN client process now
  only sends Log events to the logger service.  When a user wants to
  receive log events now, it needs to call the
  net.openvpn.v3.sessions.LogForward() method setting an enable flag
  instead of flipping the receive_log_events boolean property directly.
  The session manager will now do a proper access control to the caller
  and then tell the log service to forward Log events directly to the
  program wanting to receive Log events.  To disable this forwarding,
  the program just calls the same method and unset the enabling flag.

  This new architecture also allows multiple log forwarders to run in
  parallel without impacting the other listeners.  Each forwarding are
  now handled independently.  And forwarding Log events will no longer
  impact the session manager any more.

* Enhancement: openvpn3-as profiles can be started via systemd

  In v16_beta a new systemd unit file was introduced to make it
  possible to manage VPN sessions via systemd.  With v18_beta
  this integration has been extended to the openvpn3-as utility
  which can download a VPN profile directly from an OpenVPN Access
  Server.

  When run as root, two new options can be used:
  --systemd-start and --owner.

  The first one will instruct openvpn3-as to enable the imported
  configuration profile to be started automatically during boot.

  The --owner takes a username argument, which, when run as root,
  will transfer the ownership of this VPN profile to the given
  username.  When the VPN session is started as root, the session
  will automatically also be owned by the given user.

* Bugfix: openvpn3 session-start with web based authentication

  The instruction guide to help continue with web based authentication
  was misleading and no longer correct.  This has been improved and
  the console now contains the correct instructions.

* Bugfix: Configuration manager could mangle --verify-x509-name

  When importing a configuration file with the --verify-x509-name
  option, it would often be misinterpreted when the import was
  as a persistent configuration profile.

  This has been resolved and the internal on-disk storage format
  for persistent configuration profiles has been upgraded to correctly
  handle this type of option class, with quoted strings.

  <https://github.com/OpenVPN/openvpn3-linux/issues/90>

* Bugfix: openvpn3-service-configmgr could segfault

  If the oepnvpn3-service-configmgr could not manage to reach the
  net.openvpn.v3.log service (openvpn3-service-logger), it would
  segfault resulting in a core dump needlessly.  This has been
  resolved by adding proper error handling and gracefully exit
  with a more reasonable error message.

* Bugfix: Network Configuration state saving failing silently

  When the Network Configuration service (openvpn3-service-netcfg)
  configuration was to be written to disk and failing, the prior
  implementation ignored any errors happening.  This has been
  improved and the error is now presented to the user if there
  is an error saving the configuration file.

* Bugfix: Python based config parser can now handle legacy algorithms

  The v17_beta release introduced a --enable-legacy-algorithms flag
  to be set on a configuration profile.  This worked fine via the
  openvpn3 config-manage interface, but the Python parser lacked the
  parsing of this option.  This has now been implemented, via the
  --profile-override option.

* Bugfix: Python based config parser did not accept --auth-nocache

  The --auth-nocache is not a feature directly available in OpenVPN 3
  Core library.  But it does not block a configuration file from
  working, so this was put to the internal "ignore list".

* Bugfix: openvpn2 could some times dump spurious error messages

  If CTRL-C was performed during the shutdown phase of a VPN session,
  where it would typically wait for statistics data to be collected
  it, could print various errors about local variables being
  unavilable.  This has now been improved.

OpenVPN 3 Linux v17 (beta, Ubuntu 22.04)

This release is the v17_beta release with an additional backport of a
patch from the development branch.  This change is required to make
OpenVPN 3 Linux build on Ubuntu 22.04.  This release is therefor only
prepared for this particular distribution and version.

David Sommerseth (1):
      build: Remove hard-coded gio-unix-2.0 include paths

OpenVPN 3 Linux v17 (beta)

This release consists mostly of several enhancements of various sizes.

* Behavior change: Only AEAD ciphers available for data channel by default

  As part of the OpenSSL 3 support, non-AEAD ciphers are no longer enabled
  by default on for the data channel cipher.  That means essentially only
  AES-GCM and, if the TLS library supports it, ChaCha20-Poly1305.

  To restore the previous behaviour, the configuration profile must be
  imported via 'openvpn3 config-import' and then use an override setting:

    $ openvpn3 config-manage --enable-legacy-algorithms true --config $CONFIG_NAME

* Command line: openvpn3 config-dump

  The openvpn3 config-show command has been deprecated in favour of
  openvpn3 config-dump.  This to avoid ambiguity in behaviour with
  commands supporting --show and to more clearly indicate it is the
  configuration _file_ and not configuration profile being displayed.

* Feature: openvpn3 session-auth command

  This is a new command which can be used to interact with VPN sessions
  requiring interaction related to user authentications.  This is
  useful if the initial connection had not completed properly or that
  the server requires the user to re-authenticate.

* Enhancement: Log level improvements on client log data

  In prior releases, the default log level in the backend process
  was set to 6, which is a debug level.  With this release, the
  default log level is 3.  But this is now more easily configurable.

  - The OpenVPN 3 VPN Client process now parses and respects the
    --verb option.

  - The configuration profile can set a log-level override.

  - Running VPN sessions can be adjusted on-the-fly using the
    the new --log-level option in openvpn3 session-manage.
    Changes using this approach are instant.

  - The default log level can also be changed by editing
    /usr/share/dbus-1/system-services/net.openvpn.v3.backends.service.
    Add the '--client-log-level 6' to the program in the Exec= line to
    restore the previous default log level.

* Enhancement: Full support for --static-challenge

  Both the OpenVPN 3 client implementation and Python interface
  has gained full support for the --static-challenge option

* Enhancement: systemd user credential passing

  When starting a VPN session via the openvpn3-session@.service unit
  file, the systemd-ask-password mechanism will be used to retrieve the
  requested user credentials.

* Enhancement: VPN session ownership transfer

  For configuration profiles shared with more users, it is the
  the session owner is the user which started the VPN session.

  With this release, the configuration owner can set the
  --transfer-owner-session flag via openvpn3 config-acl.  This
  will make the configuration profile owner the session owner
  as well, regardless of which user starting the session.  The
  user starting the session will automatically be granted ACL
  entries to manage the session and access the VPN log events.

  This is useful for VPN profiles being started automatically during
  boot via the systemd openvpn3-session@.service unit file.  These
  sessions are typically started as root, but the session owner
  can end up being a different user on the system.  But the user
  need to grant access to the profile for the root user for this
  to work.

* Extend openvpn3-as with an --insecure-certs option

  In v16_beta, the openvpn3-as utility was extended to validate the
  https server certificate of the OpenVPN Access Server.  For servers
  using self-signed certificates or signed by a unknown CA, this tool
  would no longer work.  By using this option, the user instructs this
  tool to ignore such issues.

* Bugfix: Persistent configuration profiles with multiple --remote

  Configuration files containing multiple --remote lines would not
  be preserved correctly in the saved configuration profile; only the
  last entry would be stored.  This has been improved and all entries
  will now be preserved at import time.

  Beware: Configuration profiles will need to be re-imported to
  restore all the --remote entries.

* Bugfix: Fix --tls-crypt-v2 in the Python parser

  In prior releases, configurations started via the Python interface
  would fail with an error if --tls-crypt-v2 was used.  This is now
  fixed.

* Bugfix: Fix Python file loading of files with spaces in file names

  In prior releases, the configuration parser incorrectly parsed
  file names containing spaces.  This has been improved.

* Bugfix: Non-functional shell completion for config files

  The prior release regressed on shell completion for OpenVPN
  configuration files via the openvpn3 config-import and session-start
  commands.  This has been resolved in this release.

* Distro: Builds on distributions using musl instead of glibc

  Building OpenVPN 3 Linux on Alpine did not work too well as there
  were several aspects not compatible with the development stack on
  this distribution.  Both the OpenVPN 3 Core library and the Linux
  client has been modified to be able to build successfully.

* Distro: Python 3.6 or newer is now required

  As of this release, any Linux distribution with Python older
  than version 3.6 is no longer supported.  This removes the
  support for Debian 9.

OpenVPN 3 Linux v16 (beta)

This release is mostly a bug-fix release with several known issues resolved
and a few minor feature additions.

* Bug: Incompatible OCC strings sent to server

  v15_beta updated the OpenVPN 3 Core library, leading to an
  incompatibility.  This issues have now been resolved in a
  later update of the Core library.

  - OCC strings sent over the wire to the server is now always
    prefixed with TCPv4 or UDPv4.
    <https://github.com/OpenVPN/openvpn3/commit/dee1b625c3>

* Bug: DNS caching issues for long-running VPN client sessions

  Before v16_beta, the client would do a DNS lookup before
  connecting and preserve those lookups if --persist-tun was
  used.  This works fine until the configured servers changes
  IP address and no longer is reachable.  Then the client will
  go into a reconnect loop trying to connect, but no other DNS
  lookups would be done.  The Core library has implemented an
  improved approach which will trigger a new DNS lookup in cases
  where it can no longer get a connection established.

    Important related changes:
    <https://github.com/OpenVPN/openvpn3/commit/e365c44b08658>
    <https://github.com/OpenVPN/openvpn3/commit/2e3774c059705>

    NOTE: This is not a perfect solution.  Clients on networks
          utilizing NAT64 is expected to fail when connecting
          to server on an IPv4 address where it changes during
          the runtime of the client.  The best way to resolve
          this is to make the server available via IPv6 as well.

* Bug: Pushed DNS search domains didn't work well

  Several reports indicated that pushing DOMAIN or
  DOMAIN-SEARCH didn't enable them as search domains properly
  when using system-resolved.  This has been fixed by not
  tagging each domain as routing domains.  This may for some
  users change the lookup behaviour so all DNS queries are sent
  to multiple DNS servers instead of just the VPN provided DNS
  server.  We will investigate further how to reduce these
  side-effects when utilizing systemd-resolved.

* Improvement: Do not use connection timeout by default

  Both the 'openvpn3 session-start' and 'openvpn3-autoload'
  had a timeout behaviour where it would stop running if it
  didn't get a connection established within approx. 30 seconds.
  If the server is unavailable or the client is no a network
  with temporarily connection issues, this is a drawback.

  The solution is to remove the current timeout behaviour.  The
  'openvpn3 session-start' command has been extended with a
  --timeout argument which can be used to restore the previous
  behaviour.

* Improvement: openvpn3-as now requires properly signed https server
  certificates.

  Prior versions of openvpn3-as didn't verify the https server
  certificate.  This has now been fixed.

* Improvement: Add better systemd integration for sessions

  This release introduces a Python based systemd integration,
  which will start a pre-imported (openvpn3 config-import)
  configuration profile using the openvpn3-sessions@.service
  unit file.  This can also be used to start connections
  automatically during boot.

  The advantage this has over openvpn3-autoload is that it
  manages VPN sessions on-by-one, while openvpn3-autoload just
  loaded and started everything configured without any real
  session management.  Using the openvpn3-sessions@.service,
  the session status is now also available via 'systemctl' and
  log events are easily found via 'journalctl'.  If a session
  is stopped via 'openvpn3 session-manage', this is also
  reflected in 'systemctl'.

  See the openvpn3-systemd(8) man page for details:
  <https://github.com/OpenVPN/openvpn3-linux/blob/master/docs/man/openvpn3-systemd.8.rst>

  This support is not complete yet, and will be extended
  in coming releases.

* Improvement: Support for the newer WEB_AUTH pending authentication method

* Improvement: Extend openvpn3-admin with a sessionmgr-service command.

  This new command currently only supports listing
  all running VPN sessions on the host and list the owner of
  each session as well as the tun/DCO interface in use.

  See the openvpn3-admin-sessionmgr-service(8) man page for
  details.
  <https://github.com/OpenVPN/openvpn3-linux/blob/master/docs/man/openvpn3-admin-sessionmgr-service.8.rst>

* Improvement: Python based configuration parser updates

  The configuration parser used by openvpn2, openvpn3-autoload
  and the new openvpn3-systemd integration now ignores
  --ncp-ciphers, --data-ciphers and --data-ciphers-fallback

  These options was added in OpenVPN 2.4 and 2.5 as part to
  help migration from prior default ciphers to better ones.
  Connecting to some servers could need a more specific cipher
  to be set.  This is believed not to be needed in OpenVPN 3,
  so instead we just ignore these options if found.

OpenVPN 3 Linux v15 (beta)

The highlights of this release includes:

* Bugfix: 2FA authentication with dynamic challenge protocol

  Servers (most commonly OpenVPN Access Server) deployed with 2FA
  based authentication would fail when the dynamic challenge protocol
  was utilized.  The result would be a client disconnecting with a
  timeout error and in some cases the 'openvpn3 sessions-list' would
  enlist "ghost" sessions not responding.  This command would also
  wait for a long time before reporting the complete list of sessions
  when such ghost sessions are present.

  Reported: <https://github.com/OpenVPN/openvpn3-linux/issues/55>

* Bugfix: Fix misbehaviours with --tls-crypt-v2

  This feature has been a known issue for a long time, but newer
  OpenVPN Access Servers now pushes tls-crypt-v2 profiles resulting
  in connections failing with NETWORK_EOF_ERROR errors in the log.

  Reported: <https://github.com/OpenVPN/openvpn3-linux/issues/55>

* Feature: Added openvpn3-admin variables command

  This "openvpn3-admin variables" command will provide runtime
  information used by openvpn3-linux.  First variable accessible
  is the value reported in the IV_HWADDR field sent to the VPN
  server.  This can be seen using:

     # openvpn3-admin variables --machine-id

David Sommerseth (5):
      docs: Update README.md with new DCO and SELinux info
      common: Extend MachineID to provide source information
      ovpn3cli/admin: Add a new 'variables' admin command
      Revert "client/core: Improve fatal exception handling in event()"
      core-ext: Add support for inline --tls-crypt-v2

OpenVPN 3 Linux v14 (beta)

The highlights of this release includes:

* Security: [CVE-2021-3547] --verify-x509-name overrides certificate checks

  The OpenVPN 3 Core library got support for --verify-x509-name in
  commit 583986920236f7e (committed 2019-11-08).  This implementation
  would reset prior certificate checks. If a prior certificate check
  failed and the --verify-x509-name check passed, the connection would
  be accepted as valid.  This has been fixed in the Core library as
  of OpenVPN 3 Core library commit febf01ef68b84f.

* systemd-resolved - support for DNS zones

  This is the first step towards a better split-DNS support.  It
  implements the needed configuration settings to properly set up the
  global or tunnel DNS resolver scopes in systemd-resolved.  For the
  resolv-conf based mode, this setting will be ignored (and logged as a
  warning) as resolv-conf only supports a single DNS resolver.

  Currently, the tunnel scope is very simplistic and will only result in
  systemd-resolved not querying anything than pushed DOMAIN/DOMAIN-SEARCH
  domains via the DNS servers for the VPN session.  It is more a reverse
  filter, than an explicit filter.  All other "global" scopes will also be
  queried.  Domains *not* matching the DOMAIN/DOMAIN-SEARCH settings
  will be *not* queried via this VPN link.

  This behaviour is more how systemd-resolved is designed and this
  behaviour will hopefully be further improved later on.

* Improved SELinux policies

  OpenVPN 3 Linux is now able to be run on CentOS, Fedora and Red Hat
  Enterprise Linux with DCO enabled on VPN profiles and with SELinux
  policies being enforced.  The openvpn3-service-netcfg and
  openvpn3-service-client processes will now run in their own confined
  environment with further restricted access.

* The OpenVPN 3 client will report IV_HWADDR

  When connecting, the client will report back some peer information to
  the server.  Until now, the IV_HWADDR has not been provided.  This
  value is supposed to be a fixed value per connecting host.  The
  reported information is a SHA256 hash of /etc/machine-id and some
  more OpenVPN 3 Linux specific values.  If this machine-id file is not
  readable, it will generate its own value and store it under
  /var/lib/openvpn3 for a persistent value.

* Support for querying the user for HTTP proxy credentials during
  connection

* Support for inline --http-user-pass values in configuration files

* Support for inline --auth-user-pass values in configuration files

* DCO support can now be activated with openvpn3 session-start and
  openvpn2 command line front-ends

* DCO device names will now carry the name of --dev in the configuration

In addition to several bug fixes and other improvements.

OpenVPN 3 Linux v13 (beta)

The highlights of this release includes:

* Feature: IPv6 and TCP protocol support in OpenVPN Data Channel Off-load (DCO)

  The DCO feature is currently a tech-preview feature.  It is not
  targeted for production usage in its current shape.  As this is
  still under heavy development, we currently only support the latest
  Fedora releases (Fedora 32 and newer) and Ubuntu 20.04.  This
  currently requires Linux kernel 5.4 and newer.

  This release includes an updated ovpn-dco implementation which adds both
  TCP and IPv6 protocols to be used for the transport between client and server.

  If you are testing the DCO feature, also be sure you use the updated
  kmod-ovpn-dco package, or build the ovpn-dco module based on git
  commit 8f04ed862539f0.

* Bugfix: Misleading argument count when options are missing arguments
  If an option requring a certain minimum amount of arguments was missing one
  or more arguments, for example using just --keepalive 30, the error would be:

     ERR_PROFILE_OPTION: option_error: option 'keepalive' must have at least 3 arguments

  This is incorrect.  The correct number should be "2 arguments".  This has
  been fixed in the OpenVPN 3 Core library which generated this error string.

* Bugfix: Multi-factor authentication broke with v12_beta
  With the v12_beta release, web based authentication was added.  This also
  added signalling support for the CR_TEXT authentication method which was not
  intended to be added.  This resulted in many multi-factor authentication
  configurations to fail, in particular those connecting to OpenVPN Access
  Server.  This has been corrected and openvpn3-linux does no longer signal
  CR_TEXT authentication method support.

David Sommerseth (1):
      client: Don't signal support for crtext authentication

Lev Stipakov (5):
      ovpn-dco: support for various transport protocols
      core: Update to Core library with ovpn-dco transport improvements
      ovpn-dco: Update to latest git master
      ovpn-dco: truncate nonce_tail length
      ovpn-dco: remove cbc-hmac support

OpenVPN 3 Linux v12 (beta)

The highlights of this release includes:

* Feature: Web-based authentication
  For servers allowing web based authentication, OpenVPN 3 Linux
  will now pick up this authentication type request and handle
  it.  If the openvpn2 or openvpn3 user-front-end applications
  are able to open a browser window with the given URL, it will
  do so.  If not, it will present the URL needed for the further
  authentication process.  In addition, any VPN sessions awaiting
  web based authentication is also presented via the
  `openvpn3 sessions-list` command together with the authentication
  URL.

* Bugfix: OpenVPN 3 Linux configuration manager could crash
  If the openvpn3-service-configmgr program was started with the
  --state-dir argument pointing at an unreadable or non-existing
  directory, it would crash.  This has been fixed to provide a
  better error message and exit gracefully.

* Bugfix: Properly handle restart of paused sessions
  VPN sessions being paused (like via
  `openvpn3 session-manage --pause`) would not recover properly if
  it was recovered by using the `restart` method instead of `resume`.
  When trying to pause the session again, it would not do so as the
  session was considered paused already.  Resuming a VPN session
  via both the `resume` and the `restart` method are considered
  appropriate and is now handled correctly.

* Bugfix: openvpn2 running in the foreground could exit with an error
  If the openvpn2 front-end was used to start a VPN session and it
  was running in the foreground (no use of --daemon), it would present
  and error message when closing the session *if* the VPN session
  was closed via another channel (such as `openvpn3 session-manage`).
  This has been fixed and it will now exit properly if this situation
  appears, without any additional error messages.

* Bugfix: openvpn2 would misinterpret --keepalive
  The OpenVPN option parser in the Python 3 openvpn module would not
  properly parse a few arguments which used multiple arguments - such
  as --keepalive.  This has been fixed.

* Enhancements: openvpn2 now understands --tls-version-{min,max}
  In prior releases, the Python 3 openvpn module did not understand
  the --tls-version-min and --tls-version-max options.  This has been
  resolved and these options are forwarded properly to the
  configuration manager.

David Sommerseth (11):
      client: Properly reset the paused flag on session restart
      python: Improve parsing of options with multiple arguments
      python: Extend argument parser with support for --tls-version-min/max
      dbus: Add web-auth constant to ClientAttentionGroup
      client: Enable web-auth support and URL extraction
      python: Add support for handling web-auth in openvpn2

      ovpn3cli: Add support web auth via openvpn3
      ovpn3cli: Improve 'sessions-list' for sessions awaiting web auth
      configmgr: Abort properly if --state-dir processing fails

OpenVPN 3 Linux v11 (beta)

The highlights of this release includes:

* Feature: OpenVPN Data Channel Off-load (DCO)

  This features is currently a tech-preview feature.  It is not
  targeted for production usage in its current shape.  As this is
  still under heavy development, we currently only support the latest
  Fedora releases (Fedora 32 and newer) and Ubuntu 20.04.  This
  currently requires Linux kernel 5.4 and newer.

  This facilitates a brand new kernel module, ovpn-dco, where all the
  crypto operations related to the OpenVPN data channel happens directly
  inside the kernel.  The data channel operations are related to the
  tunnelled network traffic.  This has the advantage of being able to
  reduce the network packet processing overhead compared to the
  traditional tun devices.

  When using the tun interfaces with OpenVPN, the remote side sends
  encrypted network traffic to a UDP or TCP socket.  The Linux kernel
  forwards these packets from kernel space to the OpenVPN user space
  process, which decrypts the packet and extracts the unencrypted
  network traffic.  This unencrypted data is then passed to a tun
  interface, which sends the traffic back to the kernel space for
  further processing.

  The ovpn-dco module changes this packet route.  When the remote
  side sends data channel packets, the ovpn-dco kernel module will
  receive the packet and will have the encryption keys needed to
  decrypt the packet directly in the kernel space and then pass it
  directly to the virtual interface ovpn-dco manages.  If the OpenVPN
  packet from the remote side is a control channel packet, the ovpn-dco
  kernel module will pass this traffic up to the OpenVPN user space
  process.  Control channel packets are used to pass authentication
  credentials, configuration setup, data channel key exchanges, etc.

  To make use of this feature, the kmod-ovpn-dco kernel module must be
  installed on the system.  The OpenVPN 3 Linux project provides
  kmod-ovpn-dco packages for Fedora 32, 33 and Rawhide in addition
  to Ubuntu 20.04.

  On Fedora, with the openvpn3 Copr repository enabled:

      # yum install kmod-ovpn-dco

  On Ubuntu, with the openvpn3 apt repository configured:

      # apt install kmod-ovpn-dco

  With the kernel module installed, the configuration file must be
  be imported:

      $ openvpn3 config-import --config CONFIG_FILENAME --name CFGNAME

  Then the imported configuration profile must get the DCO feature
  enabled:

      $ openvpn3 config-manage --show --name CFGNAME --dco true

  To preserve this setting through reboots, consider adding --persistent
  when importing the configuration file via 'openvpn3 config-import'.

  Now everything is ready and a VPN session can be started:

      $ openvpn3 session-start --config CFGNAME

  The ovpn-dco kernel module from the openvpn3 repositories has some
  limitations:

  - No TCP support
    ovpn-dco will require a UDP connection to the server.

  - No IPv6 support
    ovpn-dco does only support IPv4 for the connection
    to the remote server.

  - Limited data channel cipher support
    ovpn-dco only supports the AES-GCM ciphers.  Support for
    more ciphers will arrive later.

  - No interface statistics available
    The ovpn-dco module has not yet implemented traffic statistics.

  All of these limitations will be resolved in future releases.  A more
  comprehensive list of what ovpn-dco is working on and will support can
  be found in the ovpn-dco project.

  WARNING:
      The ovpn-dco kernel module is under heavy development.
      This means that the API used between the kernel space
      and OpenVPN user space processes may change.  Therefore
      the kernel module version must be the same which
      OpenVPN 3 Linux has been compiled against.  Once
      the API is has become stable, this restriction will no
      longer be needed.

* Bugfix: OpenVPN 3 Linux configuration manager could crash
  If the an imported persistent configuration file would contain syntax
  errors, the openvpn3-service-configmgr process could crash (SEGV).
  This has been improved and the configuration manager will now ignore
  incorrect or corrupted persistent configuration files.

* Bugfix: openvpn3 and openvpn3-admin could sometimes crash
  Occasionally on certain hosts, the 'openvpn3' and 'openvpn3-admin'
  tools could crash unexpectedly.  This was an error related to the
  argument alias processing and has been fixed to avoid this issue.

* Enhancements: The openvpn2 bash-completion support is extended
  In prior versions, the openvpn2 command did not provide any shell
  completion help to the --config option.  This has been resolved.

* OpenVPN Access Server configuration import improvements
  The 'openvpn3-as' utility now signals to the Access Server the
  downloaded configuration profile is intended to be imported into
  a local storage.

OpenVPN Linux v10 (beta)

The highlights of this release are:

* Feature: systemd-resolved integration

  By default, OpenVPN 3 Linux will modify the /etc/resolv.conf file
  with DNS configurations pushed by the VPN server.  This release
  adds systemd-resolved as an alternative to this approach, where
  the systemd-resolved service will be in charge of querying the
  proper DNS resolvers and there will no longer be any fight over
  configuration files such as /etc/resolv.conf.

  In this release, pushed DNS configurations will be handled quite
  similar to how DNS queries has been handled before.  The DNS settings
  pushed by the VPN server will typically take precedence, but
  systemd-resolved may query other servers on other interfaces as well.
  That said, if the VPN server pushes "dhcp-options DOMAIN ....", hosts
  under that domain will in this case only be queried via the VPN tunnel
  alone.  You may call this a partial DNS-split.

  In coming releases, we will evaluate further possibilities to configure
  how DNS requests would be handled by systemd-resolved.  This could
  include modes such as full split (only query for pushed DOMAIN via the
  DNS server provided by the VPN) or exclusive VPN (DNS queries should
  only go via the VPN tunnel).

  This systemd-resolved integration requires at least CentOS 8,
  Fedora 31, 32 or Rawhide, Red Hat Enterprise 8 or Ubuntu 20.04.  Other
  distributions may work as long as it uses systemd v243 or newer.

  To enable systemd-resolved, fully ensure that systemd-resolved is
  properly configured and activated on your system.  Currently only
  Ubuntu 20.04 does that somewhat out-of-the-box (there might be some
  additional changes to nsswitch.conf is required for optimal
  performance).  Please read the available systemd-resolved
  documentation for your Linux distribution.

  Once systemd-resolved is enabled and activated, run this command
  as root before starting any VPN tunnels:

     # openvpn3-admin netcfg-service --config-set systemd-resolved 1

  and wait until the openvpn3-service-netcfg has restarted.  With
  the log-level set to 5 or higher in netcfg-service, the log file will
  include this log line:

      Network Configuration VERB2: systemd-resolved DNS configuration backend

* Feature: openvpn3 log with --config will now wait for a not-started session

  When starting the end-user session logging, prior versions required the
  VPN session to already be running before a log client could be attached.

  With this release, if the session has not already been started, the
  openvpn3 log command will wait until it sees the appropriate VPN session
  has started and will attach to it instantly.  This allows to grab the
  first log lines of a starting VPN sessions for an end-user without
  other ways of accessing OpenVPN logs.

* Improvement: openvpn3 log sanitizes new line characters better

  The log output of openvpn3 log could contain a lot of additional blank
  lines.  These has been removed and indenting has been added for multi-
  line log events to make the log output more readable.

* Improvement: openvpn3-as indicates tls-crypt-v2 support to AS

  When downloading a VPN configuration profile from an OpenVPN Access
  Server, the openvpn3-as script will now signal to the server it is
  capable of handling configurations with --tls-crypt-v2.

* Bugfix: Improper session clean-up on server triggered disconnect

  If the VPN server forcefully disconnected an already established
  session, the Session Manager would not properly track this which lead
  to lacking session details with openvpn3 sessions-list.

  This has now been resolved by properly catching a server triggered
  disconnect and properly shutting down the openvpn3-service-client
  process responsible for the session, which will properly update
  the session manager about the disconnected session.

* Bugfix: AWS integration failed to propagate routes in some AWS regions

  The openvpn3-service-aws process could in some AWS regions fail to push
  routes to the AWS-VPC, leading to a process crash.  Both the crash and
  the AWS service has been extended with more region CA certificates used
  for the request validations.  In addition it will now pick up more of
  system CA certificate file locations than before.

* Bugfix: openvpn3 command could throw unfriendly error messages

  If a user was not granted access to a running VPN session, attempting
  to access this session via openvpn3 session-manage would lead to a
  openvpn:BusProxyAccessDeniedException exception error.

  This has been improved and will now instead show "Access Denied" in
  a more user-friendly way to the user.

* Bugfix: openvpn3-service-netcfg would crash without --resolve-conf

  If the openvpn3-service-netcfg would be started without the
  --resolv-conf configuration, it would crash if the VPN server pushed a
  DNS configuration.  This has been properly resolved and it is now
  possible to start the service completely without any DNS configuration
  support.

* Bugfix: openvpn3-service-client crash on some hosts with log redirection

  If the openvpn3-service-backendstart was given the
  ' --client-log-file stdout:', this would tell it to start the
  openvpn3-service-client process with '--log-file stdout:'.  This would
  on some hosts cause a program crash instead.  This has been resolved.

* Bugfix: openvpn3-service-sessionmgr would crash on illegal log-levels

  If a user attempted to change the log-level in the D-Bus session object
  the user is granted access to with an invalid value, it would lead to a
  crash of the openvpn3-service-sessionmgr process.  This would make it
  impossible to further manage already running VPN sessions without root
  privileges.

  This has been resolved to properly rejecting invalid values as an error
  back to the calling user instead of treating it as a fatal failure.

OpenVPN 3 Linux v9 (beta)

The highlights of this release are:

* Feature: New AWS VPC add-on service (openvpn3-service-aws) which
  can be configured on EC2 Linux hosts deployed inside an AWS Virtual
  Private Cloud (VPC).  This allows the host running an OpenVPN 3 Linux
  client with this service configured to act as a proper VPN gateway
  for hosts inside the VPC.  The AWS service will update the VPC
  configuration dynamically, adding and removing routes pushed to the
  VPN client.

* Bugfix: openvpn3 session-manage --restart and --resume
  modes would not respond to re-authentication requests required by the
  VPN server

* Bugfix: openvpn3 session-start and openvpn3 session-manage
  commands would not handle CTRL-C (SIGINT) situations properly during
  the connect phase to the remote server or when asking for user input.
  Prior releases would just leave the VPN session running in the
  background.  To get rid of these background sessions the user had
  to also use openvpn3 session-manage --disconnect to really stop
  these lingering sessions.  With this update, interrupting the
  openvpn3 session-start and openvpn3 session-manage operations
  during the connect phase or when acquiring user input, will result
  in the running VPN session will be properly shutdown.

* Bugfix: openvpn2 will now properly ignore the --dev-node
  option.  This option has not functionality on OpenVPN running on
  Linux and can be safely ignored.

* Documentation: The openvpn2(1) man page now renders properly.  The
  D-Bus service documentation for net.openvpn.v3.netcfg has also
  been improved.

* SELinux: The policy file needed on hosts with SELinux enabled has
  been relocated to a more proper location for such extensions, moving
  it out of /etc/openvpn3/selinux.  A slightly modified version
  of this SELinux policy has also been accepted for inclusion in the
  upstream SELinux reference policy project.  Packagers needs to
  ensure this policy is not shipped on distributions with a recent
  enough reference policy.  See the GitHub pull-request #209 [1] in
  the SELinux referenece policy project for details.
