How to Confirmed Theo de Raadt OpenBSD 6.7 released. The uncompromising and correct, slim code-oriented OpenSource operating system has been published in the semi-annual rhythm for 25 years and is under the free BSD license. The list of innovations in OpenBSD 6.7 is as long and also includes the projects supervised by OpenBSD developers such as OpenSSH, Libressl and OpenSMTPD.
Arm in focus, PowerPC64 comes
The support for the ARM platform comes under OpenBSD 6.7 Continue going. Several new drivers make it, OpenBSD 6.7 to install at many popular arms: Improvements for ARM64 will benefit the use on the Raspberry PI 3 and especially the new added Raspberry Pi 4. In the latter, it still hooks the ACPI mode, so that a change to the classic device-tree fashion partially better.
The well-maintained ARMV7 port is intended for alter 32-bit devices such as Raspberry Pi 2 or 3 (32-bit mode). Also on rock chip-based devices like the Pine Ponebook Pro run under OpenBSD 6.7 significantly better than before and seem as arm-based notebooks next to the X86 Thinkpads to take a favorite role in developers.
A few days before the publication of OpenBSD 6.7 Twittered Mark Kettenis, who, for example, looks after the SPARC64 port, the first steps for a PowerPC64 port have gone. OpenBSD runs for a long time on old PowerPCs, here as well as most of other OpenBSD ports with version 6.7 by GCC on Clang / LLVM was fully.
Intel and AMD
For more traditional X86 systems, for example, there is long expected support for Intel AX200 WiFi chips, additional SMP skills of modern AMD processors are better exploited. The misinterpretation of AMD cores as threads was also eliminated. Problems with some USB2.0 advantages to USB3.0 controllers are fixed.
The FFS2 file system received 64-bite timestamps and block numbers and is now the standard file system for new installation on all platforms Auber Landisk, Luna88k and SGI. The pleasantly small and raft audio system of OpenBSD (SNDIO) received an API for external control over applications.
Even more security
The Safety function of UNVIL (2), which prevents applications to access to for you, not essential directories, has now been implemented in 82 application programs. PBE (2), which does not prevents essential calls of system functions, is also included in further applications.
Both techniques from preventing an exploit in the system or in an application that malware or an attacker can not move over the maximum enclosed rights, for example, a web server in the system.
Hypervisor not only for AMD64
The newly developed native hypervisor of OpenBSD (VMM / VMD) received some improvements to run guest systems less stressful for the host. Amazing is that even in hardware-based LDOM virtualization on SPARC64 systems (SUN / Oracle server of the T series), some progress has been recorded. Typical for OpenBSD projects: The syntax of the LDOM / LDOMCTL commands is partially adapted to the VMM / VMD for AMD64 systems for simplifying the administration.
OpenBSD 6.7 is now available for various hardware architectures on the mirror servers of the project for download.
