OpenVPN 3 Linux v26 (Stable release) The v26 release is a small bugfix and enhancement release. Please notice the deprecation of openvpn3-autoload. * Enhancement: Improve user feedback when a VPN profile is not valid Since the OpenVPN 3 Linux v22_dev release, the openvpn3-service-configmgr service has provided an API to validate VPN profiles it manages. This has been used in the rest of the available tools to check if everything is in order before attempting to start a VPN session. When a configuration profile was lacking certain required options, it would fail this validation. But the feedback to the user was not much helpful and the user would need to check the configuration profile manually. With the v26 release, the end user will be provided a list of required configuration options missing. * Enhancement: Set route metric value when provided via VPN session Since the very beginning of OpenVPN 3 Linux, the route metric value has been ignored. This has been improved in the v26 release and the metric values provided in the configuration profile or pushed from the VPN server will now be respected. * FEATURE DEPRECATION: openvpn3-autoload The openvpn3-autoload feature was deprecated already in the v20 release. This feature will be removed in a coming stable release. The replacement is the openvpn3-session@.service systemd unit. Please see the openvpn3-systemd man page [1] for more details. If you depend on openvpn3-autoload today, please migrate ASAP to the systemd approach. [1] <https://codeberg.org/OpenVPN/openvpn3-linux/src/branch/master/docs/man/openvpn3-systemd.8.rst> * Bugfix: Proper parsing of <connection/> tags in OpenVPN configs The internal VPN profile configuration parser did not properly parse configuration files containing <connection>...</connection> tags to configure a remote server. This has been fixed and both the openvpn3-service-configmgr and the openvpn3 Python module has been updated to support this feature. * Bugfix: Proper parsing of semicolon (;) as comment line The openvpn3 Python module did not properly parse configuration files which used semicolon (;) as a comment separator. This has been improved and both hash (#) and semicolon can now be used for comments in configuration profiles. * Bugfix: openvpn3-service-netcfg may stop on route setup errors In some corner cases, when the openvpn3-service-client (VPN client) process called the Network Configuration service (openvpn3-service-netcfg) to establish the VPN network interface, the Network Configuration service could crash and not recover, resulting in the VPN session not being able to be established. This has been improved and this error situation is now handled and logged properly. * Bugfix: Background D-Bus calls to systemd-resolved fails On some systems the D-Bus communication between the openvpn3-service-netcfg (NetCfg) process and systemd-resolved could be too slow, resulting in the NetCfg process retrying the D-Bus call. Due to an incorrect retry logic, the parameters systemd-resolved would need had been released from memory and was no longer accessible. This has been resolved and the retry logic now behaves as expected. * Bugfix: VPN session restart triggers assertion warning in logs When an on-going VPN session is attempted restarted, for example via the openvpn3 session-manage command, the NetCfg service would log an assertion warning in the system logs. This has been resolved and VPN session restarts will now work as expected. * Bugfix: OpenVPN 3 AWS-VPC fails changing IPv6 routes Due to a typo in the parameter name used for changing IPv6 routes in the AWS VPC service, setting IPv6 routes would result in an error. This has been resolved in the OpenVPN 3 Core version 3.11.5 release, which OpenVPN 3 Linux v26 has upgraded to. * OpenVPN 3 Core Library update The OpenVPN 3 Core Library has been updated to version 3.11.5, which is contains the fix for the AWS VPC route fix. It also enables building against Linux 6.16 kernel headers. Known issues: - The openvpn3-service-netcfg service does not differentiate between --dns server X resolve-domains and --dns search-domains when using the --resolv-conf mode, which is not as this feature is intended to work. This was discovered in the v24 release and is on the schedule to be fixed in the next releases. When this gets fixed, only --dns search-domains will be considered as search domains and --dns server X resolve-domains will enable split-DNS when using --systemd-resolved and otherwise ignored when using --resolv-conf with openvpn3-service-netcfg. Supported Linux distributions ----------------------------- - Debian: 12, 13[*] - Fedora: 41, 42 - Red Hat Enterprise Linux 8, 9, 10[*] - Ubuntu: 22.04, 24.04, 25.05 Installation and getting started instructions can be found here: <https://community.openvpn.net/openvpn/wiki/OpenVPN3Linux> There are in addition other Linux distributions now providing OpenVPN 3 Linux packages. These distributions are primarily supported by their respective distribution communities. We will naturally review and apply fixes deemed needed for any distributions as they occur. NOTE: Red Hat Enterprise Linux 10 The Fedora Copr repository definition for RHEL+EPEL-10 *may* use a wrong URL. After doing the 'dnf copr enable' step on RHEL-10, please ensure the URL contains 'rhel+epel' and not just 'epel'. This is expected to automatically improve with time. The stable repositories provided by OpenVPN Inc should not have this issue. NOTE: Debian 13 (Trixie) Debian 13 is added to the list of supported distribution versions. With Debian 13 there is now also an upstream distribution package as well, openvpn3-client, as well as the GDBus++ library. The version in the distribution repository is at OpenVPN 3 Linux v24.1. This cannot be upgraded to a newer base line, due to Debian packaging rules. The package maintainer will apply bug and security fixes as needed. If you want to use a newer OpenVPN 3 Linux on Debian 13, you will need to install the third-party repository provided by OpenVPN Inc. This is the same procedure as in Debian 12 and earlier. With the v26 release, the package has been renamed to 'openvpn3-client' and an upgrade path from the openvpn3 package has been added. After upgrading to v26, the openvpn3 transitional package can be removed via 'apt autoremove'. -- kind regards, David Sommerseth OpenVPN Inc ---- Source tarballs --------------------------------------------------- * OpenVPN 3 Linux v26 <https://swupdate.openvpn.net/community/releases/openvpn3-linux-26.tar.xz> <https://swupdate.openvpn.net/community/releases/openvpn3-linux-26.tar.xz.asc> * GDBus++ v3 <https://swupdate.openvpn.net/community/releases/gdbuspp-3.tar.xz> <https://swupdate.openvpn.net/community/releases/gdbuspp-3.tar.xz.asc> ---- SHA256 Checksums -------------------------------------------------- 80e35615ae913fbdbdda53495b27934a3bbb21d8b15c49a624d4992c15e196e1 openvpn3-linux-26.tar.xz 474ba43ae9a6f4e8e5488750ed779bf57e7e2efe9bc05d196f65adb83f830eb4 openvpn3-linux-26.tar.xz.asc c7a053a13c4eb5811a542b747d5fcdb3a8e58a4a42c7237cc5e2e2ca72e0c94e gdbuspp-3.tar.xz b9cf732d7a347f324d6a5532dc48f80c2815dbf6704c169b4ee97a411506a99b gdbuspp-3.tar.xz.asc ---- git references ---------------------------------------------------- git repositories: - OpenVPN 3 Linux <https://codeberg.org/OpenVPN/openvpn3-linux> (PRIMARY) <https://gitlab.com/openvpn/openvpn3-linux> (code-only mirror) <https://github.com/OpenVPN/openvpn3-linux> (code-only mirror) git tag: v26 git commit: 42ecc42a782025f8774e907a8c1966524424bcee - GDBus++ <https://codeberg.org/OpenVPN/gdbuspp/> (PRIMARY) <https://gitlab.com/openvpn/gdbuspp/> (code-only mirror) <https://github.com/openvpn/gdbuspp/> (code-only mirror) git tag: v3 git commit: 96f7fb688ed2dea3f192c63c5fe283dbe4900f16 ---- Changes from v25 to v26 --------------------------------------- David Sommerseth (30): build: Add fmt subproject configmgr: Add details when profile validation fails ovpn3cli/config-import: Show warning if imported profile is invalid netcfg/resolved: Ensure glib2 params are available on retries common: Refactor and clean-up core-extensions.hpp common/core-extensions: Move helper functions into OptionListJSON class tests: Parse Access Server meta options in config-export-json-test common: Properly parse <connection/> blocks netcfg: Catch Core library exceptions in method_establish() configmgr: Let <connection/> tags be equivalent to --remote when validating the profile python: Deprecate openvpn3.ConfigParser.SanityCheck() python/openvpn2: Make Configuration.Validate() errors more user friendly python/openvpn2: Add IMPORT_ONLY debug more python: Implement <connection/> tag support in ConfigParser netcfg: Clarify IP address 'prefix' usage netcfg: Split up the NetCfgProxy::Network object construction netcfg: Small clean-up/codestyle fixup for IPAddr, Network and VPNAddress classes netcfg: Add support for route metric when assing VPN routes netcfg/proxy: Add service version check for D-Bus API compatibility python: Semicolon is not accepted by openvpn3.ConfigParser common: Minor cleanups in cmdargparser code netcfg/resolved: Fix g_variant_ref assertion warning on session restarts core: Update to OpenVPN 3 Core Library v3.11.4 docs: Minor updates to the coding style guide Code style cleanup git: Update .git-blame-ignore-revs ignoring last code-style changes Quick spellcheck fixes all over project configmgr: Fix auth-user-pass handling regression netcfg: Make logged metric details more user friendly core: Update to OpenVPN 3 Core Library v3.11.5 -------------------------------------------------------------------- |
