OpenBSD 5.8 发布预览,计划10月18日正式推送

主要改进如下:

  • 改进硬件支持:

    • New rtwn(4) driver for Realtek RTL8188CE wifi cards.

    • New hpb(4) driver for HyperTransport bridges as found in the IBM CPC945

    • The ugold(4) driver now supports TEMPerHUMV1.x temperature and humidity sensors.

    • Improved sensor support for the upd(4) driver for USB Power Devices (UPS).

    • Support for jumbo frames on re(4) devices using RTL8168C/D/E/F/G and RTL8411, including PC Engines APU.

    • re(4) now works with newer devices e.g. RTL8111GU.

    • Partial support has been added for full-speed isochronous devices in ehci(4) , allowing USB 1.1 audio devices to be used on EHCI-only systems in some cases.

    • Improved macppc stability and G5 performances with MP kernels

    • acpicpu(4) uses ACPI C-state information to reduce power consumption of idle CPUs.

    • Kernel supports x86 AVX instructions on CPUs that have them.

    • Avoid assigning low address to PCI BARs, fixing various issues on machines whose BIOSes neglect to claim low memory.

    • wscons(4) works with even more odd trackpads.

    • Added pvbus(4) paravirtual device tree root on virtual machines that are running on hypervisors.

    • New octdwctwo(4) driver for USB support on OpenBSD/octeon.

    • New amdcf(4) driver for embedded flash on OpenBSD/octeon.

    • ...

  • 移除的硬件支持:

    • The lmc(4) driver for Lan Media Corporation SSI/T1/DS1/HSSI/DS3 devices has been removed.

    • The san(4) driver for Sangoma Technologies AFT T1/E1 devices has been removed.

    • ...

  • 常规网络栈改进

    • MTU of vlan(4) devices can now be set independently from the parent interface's MTU.

    • The same network range can now be assigned to multiple interfaces, using interface priorities to choose between them.

    • New  MPLS pseudowire driver mpw(4) .

    • ...

  • 安装器改进

    • hostname-mode.conf response file names.

    • response files to be placed in a subdir of the webserver's document root.

    • passing a template file to disklabel(8) to automatically partition the disk.

    • The default answer is now 'no'.

    • 'prohibit-password' has been added to the list of possible answers.

    • The logic of the 'Allow root ssh login?' question has been changed.

    • autoinstall(8) has been extended to allow

    • ntpd(8) is now enabled by default at install time.

    • DUID support has improved enough that new installs now use them unconditionally.

    • Installing sets from CD-ROM has been fixed if more than one CD-ROM drive is present.

    • The 'Which CD-ROM contains the install media?' question has been removed.      Available cdrom devices are now shown directly in the 'Location of sets?' prompt.

  • 安全改进:

    • sudo in base has been replaced with doas(1) , sudo is available as a package.

    • file(1) has been replaced with a new modern implementation, including sandbox and privilege separation.

    • pax(1) (and tar(1) and cpio(1)) now prevent archive extraction from escaping the current directory via symlinks; tar(1) without -P option now strips up through any " .. " path components.

    • Improved kernel checks of ELF headers.

    • ...

OpenBSD是一个从NetBSD衍生出来的类Unix操作系统。专案领导人Theo de Raadt在1995年]发起了OpenBSD专案,希望创造一个注重安全的操作系统,此外OpenBSD也以高品质的文件、坚持开放程式码以及严格的软 件授权著名。OpenBSD的吉祥物是河豚。

OpenBSD包含了一些在其他操作系统缺少或是选择性的安全功能,此外OpenBSD极度重视程式码的品质,任何对核心的修改都需要经过严格的程 式码审阅。OpenBSD可以在17种不同的硬件环境下运作,包含DEC Alpha、Intel i386、Hewlett-Packard PA-RISC、AMD64、Motorola 68000、PowerPC、Sun SPARC等。
