21.7 “Noble Nightingale” Series

For more than 6 and a half years, OPNsense is driving innovation through modularising and hardening the open source firewall, with simple and reliable firmware upgrades, multi-language support, fast adoption of upstream software updates as well as clear and stable 2-Clause BSD licensing.

21.7, nicknamed “Noble Nightingale”, is one of the largest iterations of code changes in our recent history. It will also be the last release on HardenedBSD 12.1. We are planning to start the work on FreeBSD 13 as soon as next week for the 22.1 series.

The installer was replaced to offer native ZFS installations and prevent glitches in virtual machines using UEFI. Firmware updates were partially redesigned and the UI layout consolidated between static and MVC pages. The live log now contains the actual rule ID to avoid mismatches after adjusting your ruleset and the firewall aliases now also support wildcard netmasks. For a complete list of changes see below.

Download links, an installation guide [1] and the checksums for the images can be found below as well.

21.7.8 (January 27, 2022)

To improve migration to the next version we are releasing this update back to back with 22.1. There is no immediate need to upgrade so plenty of time to read and prepare.

21.7.7 (December 15, 2021)

End-of-the-year security and reliability update coming right up!

Due to inconclusive reports we are disabling the Netmap API version 14 support in Suricata to get a better understanding of the situation. The plan still is to keep it for the 22.1 upgrade and it has in fact been enabled on the development versions since September without any obvious issues.

21.7.5 (November 11, 2021)

FreeBSD security advisories and an issue with Intel-based ixgbe driver with “ifconfig -v” stalls keep this release rolling. Also note that OpenSSH was updated to version 8.8 which deprecates ssh-rsa usage which is mainly an issue for client access from the OPNsense system to the outside and can be amended as per the suggestions in the respective release notes.

And as promised the development version includes the upgrade path to the 22.1-BETA1 release. This will be an online-beta with a few iterations over the FreeBSD 13 stable branch and eventually move to FreeBSD 13.1 release as that becomes available.

Highlights for 22.1 already include:

  • Suricata Netmap version 14 support for multi-gigabit speed in IPS mode with RSS enabled

  • Separate VLAN MAC spoofing and permanent promiscuous mode setting

  • Tunable analytics provide automatic descriptions and type

  • IPsec tunnel overview ported to MVC with pagination

  • Proofpoint Emerging Threats rules for Suricata 5.0

  • Removed opportunistic interface address read functions

  • Console-based LAGG configuration support

  • Removed state killing on gateway failure feature

  • Improved firmware update capabilities

  • No-bind service awareness for virtual IPs

  • FreeBSD 13 stable branch

  • RFC 5424 and severity support in logs

  • Clog support has been removed

  • And more…

Please note that the beta version will always be available for upgrade when switching to the development version. At this point no stable packages are provided and this includes plugins. These will become available as the release candidate is released in early January 2022.

All feedback is welcome but keep in mind that there are still a number of moving parts ahead. Upgrade responsibly.

21.7.4 (October 27, 2021)

This update features three new major things: optional receive side scaling (RSS) support in the kernel, asynchronous DNS resolving for aliases and configuration support for advanced LAGG settings.

RSS is disabled by default but may be switched on by adding a tunable “net.inet.rss.enabled” with value “1” and rebooting the system. While RSS can improve performance for certain hardware it should be used with care at this point and is not generally recommended yet! The Suricata version bundled with the development release offers the upcoming API bindings to take advantage of the RSS-based multithreading. Also please note that PPPoE cannot take advantage of RSS.

On the side we are almost ready for our 22.1-BETA preview with rolling releases for the development release type which is something new to look forward to also.

Here are the full patch notes:

  • system: prevent expired or intermediate CA certificates from being added to trust store by default

21.7.3 (September 22, 2021)

This release finally brings in Suricata version 6 as well as OpenVPN tls-crypt support, automatic user creation on LDAP-based logins and more.

As a general note the Realtek vendor driver currently bundled with the base system will be moved to a plugin-based kernel module in version 22.1 and the original re(4) driver inside FreeBSD 13 will be restored. To ease migration and because the version maintained in FreeBSD ports actually offers additional fixes we have included the new plugin into this build.

Here are the full patch notes:

  • system: allow automatic user creation on LDAP-based logins

  • interfaces: add and use unified function is_interface_assigned() to prevent deleting assigned interfaces

  • interfaces: sync firewall groups after internal create/destroy operations

  • interfaces: add netstat tree search and improve page layout

  • interfaces: replace opportunistic diagnostics IP address lookups with more robust variants

  • firewall: clarify match/set priority in rules

  • firewall: improve alias description/preview

  • firewall: aliases maximum entries progress bar

  • dhcp: add shared dhcpd_leases() reader and use it in both lease pages

  • openvpn: use is_interface_assigned() to prevent deletion of assigned instances

A hotfix release was issued as 21.7.3_3:

  • openvpn: fix validation for /30 subnet in peer to peer mode (contributed by kulikov-a)

  • backend: catch broken pipe on event handler (contributed by kulikov-a)

  • plugins: os-acme-client 3.2 [1]

21.7.2 (September 07, 2021)

Today the following CVEs are being addressed:

CVE-2021-3711, CVE-2021-3712, CVE-2021-23840, CVE-2021-23841

Please note that the Let’s Encrypt client plugin is now called ACME client since acme.sh version 3 does support multiple providers.

Apart from the usual batch of fixes the work on RSS (receive side scaling) is progressing and groundwork has already made it to the kernel along with the libnetmap library for allowing better scaling in netmap mode along with it. At this point, however, RSS is not yet enabled and there is no impact on existing setups. That will likely change with one of the next stable versions in this series.

On the other hand, the work for FreeBSD 13 migration in 22.1 is ongoing as well to be able to test this rather sooner than later. In this iteration we will take the time to look at shared forwarding edge cases and have already upstreamed a number of patches that have been accumulated over the last couple of years to keep our code base light and tidy.

21.7.1 (August 04, 2021)

After some initial trouble with particular Intel network card instability and two installer shortcomings this brings the first round of stable updates, general improvements and even new features.

The OpenVPN integration required a few more changes for the 2.5 series and Unbound would stall when the new cache restore feature was caching an empty response.

21.7 (July 28, 2021)

For more than 6 and a half years, OPNsense is driving innovation through modularising and hardening the open source firewall, with simple and reliable firmware upgrades, multi-language support, fast adoption of upstream software updates as well as clear and stable 2-Clause BSD licensing.

21.7, nicknamed “Noble Nightingale”, is one of the largest iterations of code changes in our recent history. It will also be the last release on HardenedBSD 12.1. We are planning to start the work on FreeBSD 13 as soon as next week for the 22.1 series.

The installer was replaced to offer native ZFS installations and prevent glitches in virtual machines using UEFI. Firmware updates were partially redesigned and the UI layout consolidated between static and MVC pages. The live log now contains the actual rule ID to avoid mismatches after adjusting your ruleset and the firewall aliases now also support wildcard netmasks. For a complete list of changes see below.

Download links, an installation guide [1] and the checksums for the images can be found below as well.

Here are the full patch notes:

  • system: Norwegian translation (contributed by Stein-Aksel Basma)

  • system: correctly enforce “Disable writing log files to the local disk” when circular logs are not used

  • system: allow to edit gateway entries with non-conforming names

  • system: add HA sync entry for live log templates

  • system: lock config writes during HA merges

  • system: raised PHP memory limit to 1G

  • system: raised encryption standard for encrypted config.xml export

  • system: removed NextCloud backup from core functionality

  • system: allow more characters in the certificate/authority organization fields (contributed by Jan De Luyck)
