Sebastian Benoit (benno@) announced the release of version 9.2 of rpki-client, the essential component for routing security.

See the full announcement for further details.

Here are some key excerpts from the release announcement:

This release includes the following changes to the previous release: - Ensure synchronization jobs are stopped when the timeout is reached. - Fix a corner case in repository handling. If the last RRDP repository failed to load, rpki-client would fail to fall back to rsync due to an ordering bug in the event loop. - Improve detection of duplicate file paths. Only trigger a duplicate error if a valid path is revisited otherwise a bad CA could prevent legitimate files from being considered valid. - Normalize internal representation of the caRepository to have a trailing slash and ensure that the rpkiManifest is a file inside it.

All files from the original import of OpenBSD have now been modified (or deleted). Appropriately, Theo de Raadt (deraadt@) made the change:

CVSROOT: /cvs Module name: src Changes by: deraadt@cvs.openbsd.org 2024/08/23 11:29:08 Modified files: games/quiz : Makefile games/quiz/datfiles: index Added files: games/quiz/datfiles: ship Removed files: games/quiz/datfiles: greek Log message: The greek quiz is so obscure that it is ridiculous -- noone can play this. Replace it with a new quiz about galley (ship) parts. This commit changes the *LAST UNMODIFIED ORIGINAL FILE* (meaning revision 1.1.1.1) from the original import that created OpenBSD on Oct 18, 1995. With this commit, we have completed an amusing mission of replacing the final parts of the original OpenBSD. We have reached OpenBSD of Theseus. ideas & assistance from mglocker, naval terminology help from jmc

As an update to a earlier post…

The BSDCan 2024 video playlist is now complete and available on both YouTube and Peertube.

OpenBSD -current has moved to 7.6-beta in preparation for the next release with this commit.

The release is traditionally about November 1st, but we shall see what happens this year. Snapshots are already beginning to show up on the mirrors.

In an exciting move, Mike Larkin (mlarkin@) has requested hardware for vmm(4) development on the arm64 platform:

CVSROOT: /cvs Module name: www Changes by: mlarkin@cvs.openbsd.org 2024/07/27 18:31:12 Modified files: . : want.html Log message: Mac mini M2 needed for vmm(4) development.

This follows several earlier commits [by Dave Voutila (dv@)] splitting vmm(4)/vmd(8) into MI and MD parts.

Support for UDP parallel input [on which we reported previously] has been committed to -current by Alexander Bluhm (bluhm@):

CVSROOT: /cvs Module name: src Changes by: bluhm@cvs.openbsd.org 2024/07/26 08:38:20 Modified files: sys/netinet : in_proto.c sys/netinet6 : in6_proto.c Log message: Run UDP input on multiple CPU in parallel.

UDP input is about to become faster and parallel on OpenBSD. In a message to tech@ titled UDP parallel input, Alexander Bluhm (bluhm@) offers a diff that enables parallel UDP input for -current.

The message reads,

List: openbsd-tech Subject: UDP parallel input From: Alexander Bluhm <bluhm () openbsd ! org> Date: 2024-07-23 13:40:21 Hi, mvs@ has completed the final bits to make socket buffer MP safe for UDP packets. This means that we can run UDP input on multiple threads. Diff below activates this.

In this commit, Rafael Sadowski (rsadowski@) merged libva 2.22.0 into OpenBSD, enabling VA-API to accelerate video decoding and other hardware assisted operations:

In a recent post to tech@ titled let's make pf(4) anchors and tables better friends (possibly originating at the ongoing hackathon) Alexandr Nedvedicky (sashan@) introduced code to enable creating local tables inside anchors in pf(4) rulesets:

Crystal Kolipe writes in about a new article posted by the crew at Exotic Silicon on fun things to do with OpenBSD -- Implementing a self-managed, dual-stacked VPN.

Today we're showing you how to use iked to tunnel both IPv4 as well as IPv6 to a remote server for a self-managed VPN. We're doing all this with utilities from the OpenBSD base system so the setup is nice and sleek, completely avoiding the need to install countless programs from ports.

Not only that, but we'll also show you how to isolate the VPN traffic in it's own routing domain so it can be used only when required, (or if you're really clever like us, you can even configure more than one simultaneously).

Of course, the setup supports inbound connections too, so you can run servers from diverse physical locations whilst using the inbound address space and connectivity of the datacentre. Stuck without IPv6 or inbound connectivity at home? Not anymore! All this excitement and even more is right here waiting for you in setting up an IPv6 capable VPN. Read it today!

While we were busy with other things, Theo de Raadt (deraadt@) is continuing the work on bringing the clang option to clean return addresses off the stack, as reported upon earlier, to OpenBSD/arm64.

Theo posted an early version of the code to tech@, saying

List: openbsd-tech Subject: arm64 -fret-clean attempt From: "Theo de Raadt" <deraadt () openbsd ! org> Date: 2024-07-02 5:50:45 I've been trying to write -fret-clean for arm64. On a return-stack architecture like amd64, the callee has to clean up the word on the stack upon return. arm64, like some other risc architectures, is a link-register architecture. In this case, the return address is saved in some temporary location by the caller, who loads it into the link register before returning. Before that moment, the caller has to clean it up.

In a fediverse post, Damien Miller (djm@) announced the availability of the new OpenSSH version 9.8: OpenSSH 9.8 has just been released. This release includes a fix for a critical race condition in sshd that could be exploited for remote code execution so you should definitely patch or upgrade. It also contains a fix for a minor issue in ssh that saw the recently-added ObscureKeystrokeTiming feature work the opposite way as intended.

There are some new features too. Please see the release notes at https://openssh.com/releasenotes.html for more details

Friends, dhclient(8) in OpenBSD is no more, at least for those of us running -current.

For some of us it is basically in muscle memory to type doas dhclient $wifiinterface when visiting somewhere, but from this day forward we will rely on dhcpleased(8) to do its job, which in my own experience does admirably.

In this commit, Theo de Raadt (deraadt@), executed the removal.

The commit message reads,

We are releasing an initial playlist of 28 BSDCan Videos.

The OpenBSD focused: Why rewrite fw_update(8)? By: Andrew Hewus Fresh

We have 6 videos in need of additional work and expect them to be released in the coming month. We will also release to Peertube. I will update this post accordingly. We now know how quite a few of us will spend the next few hours and possibly days, while we eagerly await the arrival of the final six.

The OpenBGPD project announced that a new version the Border Gateway Protocol dameon, OpenBGPD 8.5 has been released. The release comes with a number of new features and refinements, and marks another step in the development of secure and reliable routing management.
