OpenBSD 8.0 arrives with security record still intact
摘要
OpenBSD 8.0 正式发布，这是该项目第61次发布，延续自1996年以来每半年一次的发布节奏。OpenBSD 创始人 Theo de Raadt 在公告邮件中强调项目保持“默认安装三十多年仅出现两个远程漏洞”的纪录。新版本带来多项改进，包括支持 Intel Arc A 系列显卡、AMD64 内核虚拟地址空间从4GB扩展至512GB以支持大于4GB的显存
OpenBSD 8.0 is here, marking the project's 61st release and continuing its schedule of semiannual releases dating back to 1996. What started more than 30 years ago as a fork of NetBSD has grown into one of the most security-conscious operating systems in active development. In a post to the project's announcements mailing list, OpenBSD founder Theo de Raadt highlights a host of improvements included with the latest version and writes that the project remains "proud of OpenBSD's record of more than thirty years with only two remote holes in the default install."
The latest OpenBSD version brings new features and improvements across the board. These changes, particularly the new Intel Arc support and expanded virtual address space, should improve compatibility with modern graphics cards and allow the system to map more than 4 GB of VRAM. Some of the major updates noted in the release newsletter are as follows:
- Added support for Intel Arc A-Series (DG2/Alchemist) graphics cards.
- 512 GB kernel virtual address space on AMD64, up from 4 GB, allowing VRAM mapping above 4 GB.
- Added hibernation support for ARM64 systems.
- A new RPKI-to-router daemon: rtrd(8).
- RISC-V improvements including kernel support for the 'V' vector extension and support for Advanced Interrupt Architecture.
- Wireless network driver additions and improvements, including 802.11n and 40 MHz channels for the qwx(4) wireless driver.
- Added support for up to 64 virtual CPUs per guest virtual machine.
- Security and internal improvements for LibreSSL 4.4.0 and OpenSSH 10.6.
- Improvements to the vmm/vmd virtualization stack.
