OpenBSD/arm64 on Hetzner Cloud  

Hetzner introduced its Ampere Altra powered arm64-based cloud servers earlier this year, making it possible to easily run OpenBSD/arm64 on their platform. The only caveat for now is that the viogpu(4) driver is required, which was committed by jcs@ in April 2023 and thus only available in snapshots. It will first appear in OpenBSD 7.4.

FreeBSD Security Advisory  

IPv6 fragments may bypass firewall rules written on the assumption all fragments have been reassembled and, as a result, be forwarded or processed by the host.

FreeBSD Errata Notice FreeBSD-EN-23:11.caroot  

Several certificates were added to the bundle after the latest release of FreeBSD 13.2. TLS connections using the missing root certificates as a trust anchor would not be trusted causing an error.

FreeBSD Errata Notice FreeBSD-EN-23:10.pci  

The code which allocated the hot-plug interrupt did not allocate MSI-X vectors properly. When attaching to devices which support only MSI-X messages, the interrupt would not be allocated. PCIe hot-plug would fail to work for certain devices. In particular, this affects certain Amazon EC2 instance types which require functional hot-plug support in order to attach network devices.

FreeBSD Errata Notice FreeBSD-EN-23:09.freebsd-update  

freebsd-update incorrectly deleted files in /etc/ in the event the file to be updated matched the new release and was different than the old release. This has not been an issue previously because the $FreeBSD$ tag expansion from subversion virtually guaranteed the existing file was going to be different from the new release. With the conversion to git in the 13.x releases, $FreeBSD$ is no longer expanded, making it much more likely that a file would find this issue.
