- **Place:** #openvpn-meeting channel on LiberaChat IRC network

- Weak ciphers like 3DES and BF-CBC - what to do with them and when?

- Originally it looks like it was planned to remove in 2.7 but that may be too soon.

- For example, OpenVPN Inc. still sees customers with 10+ year old installations fairly regularly.

- A proposal to consider may be to deprecate it when crypto libraries deprecate it.

- Weighing the expected complaints versus the low cost of just maintaining weak ciphers until crypto libraries deprecate them - the choice seems obvious.

- For now, we'll stick with letting weak ciphers stay in unless there is some convincing reason to remove it.

- This was released on 20th of March.

- This was released on 21st of March, including new Windows installers.

- ordex convinced OTF (Open Tech Fund) to let OpenVPN join the "FOSS sustainability funding pilot run."

- This allows paying for allocated hours for mattock and cron2 to work on OpenVPN community tasks.

- Some ongoing tasks are listed under 'Mattock Topics' in the meeting notes and have already been ongoing for a while.

- This topic is therefore considered closed for now.

- It looks like openvpn2 and openvpn3 handle the counting of traffic differently.

- After some discussion, it was decided illia will submit some suggested fixes.

- This will now follow standard procedure for patch submission and review. Closing topic.

- Looks like Tunnelblick implemented a fix on their end.

- [OpenVPN Issue #525](https://github.com/OpenVPN/openvpn/issues/525)

- Last week a website release was planned that would enable a new way for updating the Community Downloads page.

- Postponed to this week. We'll see.

- ecrist still working on forums. Admin access issue looks resolved. Email issue looks resolved.

- Plan is to soon switch URLs so new forum is on forums.openvpn.net and old forums is on archive address.

- Email confirmation on registration was suggested.

- We still need to work on having some other people with some admin or high mod access.

- Mod guide, hard or soft delete (chuck board?), what to do with GDPR, etc. (write it down and actually make it available to mods, maybe a hidden topic)

- Access for mods to logs so one can see what others did.

- Upstreaming DCO to Linux is proceeding, it is in review stage at the moment.

- ordex will prepare a v3 patchset soon based on feedback received.

- There will be an API change that makes it incompatible with the current implementation.

- A graceful solution to that was already discussed and in motion. giaan will be working on this.

- (in a nutshell, make OpenVPN understand old and new API, DKMS and kernel versions both will then use new API, then we drop old API)

- Made it so --dev null tests can run arbitrary numbers of servers concurrently, and have arbitrary amount of clients run in parallel to these servers.

- Will probably look into separating the --dev null test data (test cases) from the test scripts.

- Also started on debian snapshot publishing but didn't get very far there yet.

- dazo and novaflash will start discussing this internally in openvpn inc.

- Goal of discussions is to work out a better internal procedure to connect security mailing list better with company product responsible people.

- ordex consulted an expert and it looks like doing a legal entity does not make sense when you're just starting out.

- The tricky part here is that only if we get a lot of donations and a lot of money does it make sense to have that kind of overhead.

- What we can do is start out with a company that collects the money and puts it to good community use. ordex volunteers to take this on.

- We want the donations to be collected in one place, and expenses made from that one place, so we are accountable.

- We need to figure out how to deal with that legally, and what payment methods to accept and how.

- Probably credit card is a must. Maybe PayPal as well. Bitcoin seems to encounter some resistance in the discussions.

- And a reminder; we definitely do not want the donation thing to be forced - have a mechanism to do it, but keep it out of the way.

- There was a discussion between MaxF and djpig and others.

- For OpenVPN2 / OpenVPN-NL, there is not much overlap, as OpenVPN2 doesn't ship much in terms of libraries, but OpenVPN-NL does.

- The interesting use-case for an SBOM is really the OpenVPN Windows GUI client.

- No progress since last meeting.

- This will probably have to wait until "--dev null" is done

- Should have access controls so only approved members can edit.

- Current status: when mitigations start appearing we will mention them in meeting notes.

- Naming: We decided to rename from 'Hackathon' to 'OpenVPN community meetup'. This has a more open spirit to it, as we want to encourage developers and those interested in contributing to feel welcome.

- Where: Karlsruhe, Germany. It is a relatively central location in Europe and is fairly easily reachable by train. A meeting location is yet to be arranged.

- When: At the moment tentatively set to 20-22 September 2024.

- Who: We'll do an open invitation to openvpn-devel mailing list, but also CC: specifically past attendees and people of interest.

- Shirts: There is plenty of time still to prepare a shirt design.

- This page is outdated badly: [Static-key mini how-to](https://openvpn.net/community-resources/static-key-mini-howto/)

- Company will send this to a tech writer to redo based on [example-fingerprint info](https://github.com/OpenVPN/openvpn/blob/master/doc/man-sections/example-fingerprint.rst) and also retain a link to that GitHub doc.

- Having a simple guide online will help adoption

- Tests should cover: GRE, IPSec, userland, DCO

- Linux, FreeBSD, Windows

- Requires time to be dedicated to doing this, when time available will do it

- Matt provided icons in [OpenVPN GUI Issue #595](https://github.com/OpenVPN/openvpn-gui/issues/595)

- Last update: will be picked up by selva when he has time

- Company switched EV code signing to cloudhsm, this is the same cert type we use for driver signing, is also suitable for binary signing.

- In future, we could possibly switch community to that same key. Saves having to maintain 2 different keys.

- Depends on how hard/easy it is to access company key signing thing from community infrastructure.

- Also no high priority at the moment, we have a working solution now.

- Novaflash will pick this up at some point

Mattock has implemented the first version of the so-called "--dev null server testing" and integrated it with "make check". The features are:

- Does what it says on the tin (more on that later)

- Mostly operating-system agnostic

- Should be POSIX shell compliant

- Uses the sample certificates and keys

- Supports running directly as root and with sudo

- Supports using different OpenVPN client versions

- The "current" (just compiled) version

- Any other OpenVPN versions (must be present on the filesystem)

- Support testing for success as well as failure

- Server configuration is currently static (i.e. no support for multiple server configurations yet)

- How would we go about running OpenVPN 2.4, 2.5, 2.6, etc. clients against the "--dev null server"

Here's how it works:

1. **make check**

1. **t_server_null.sh**

1. **t_server_null_server.sh**

- Launches the compiled OpenVPN as root (if necessary with sudo)

- OpenVPN server exits when all clients have been disconnected for ten seconds, based on its status file

1. **t_server_null_client.sh**

- Launches each individual client test

- Client kills itself after some delay using an "--up" script

Current PoC code is available in mattock's "dev_null" branch. A good starting point is [t_server_null.sh](https://github.com/mattock/openvpn/blob/dev_null/tests/t_server_null.sh).

What should be the next steps?

- Basic approach ok?

- Is starting with a single server configuration ok?

- Which server configuration(s) should we test against?

- Which client configurations should we test (success or failure)?

- Which operating systems do we want to support in this context? Linux and BSDs? Something more esoteric?

- Which OpenVPN client versions should we run?

- In the last meeting we agreed to publish snapshot Debian/Ubuntu packages on *build.openvpn.net*

- The tool to use to publish is [aptly](https://www.aptly.info/)

- Aptly does not have direct support for running commands (e.g. rsync, scp) after publishing packages, e.g. to a local filesystem on the buildmaster

- **Option 1 (hacky):** use inotifywait with rsync or scp to copy the published repo to build.openvpn.net

- **Option 2 (less hacky):** use NFS to publish "directly" to build.openvpn.net

- Both options require a fair amount of tinkering
