OpenBSD 6.0 发布，多项功能改进增强
欢迎加入运维网交流群：263444886OpenBSD 6.0 发布了，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。
该版本改进如下：
[*] 默认启用内存保护策略W^X（也就是内存页要么可写要么可执行，无法两者兼具）；
[*] ARMv7平台支持EFI + bootloader；
[*] 改进硬件支持；
[*] 改进 IEEE 802.11 无线网络协议栈；
[*] 软件更新如OpenSMTPD 6.0.0、OpenSSH 7.3、OpenNTPD 6.0和 LibreSSL 2.4.2；
[*] 移除VAX支持、Linux模拟和kern.usermount，等等
New/extended platforms:
[*] armv7:
[*] EFI bootloader added, kernels are now loaded from FFS instead of FAT or EXT filesystems, without U-Boot headers.
[*] A single kernel and ramdisk are now used for all SoCs.
[*]
Hardware is dynamically enumerated via Flattened Device Tree (FDT) instead of via static tables based on board>
[*] Miniroot installer images include U-Boot 2016.07 with support for EFI payloads.
[*] vax:
[*] Removed.
[*] Improved hardware support, including:
[*] New bytgpio(4) driver for the Intel Bay Trail GPIO controller.
[*] New chvgpio(4) driver for the Intel Cherry View GPIO controller.
[*] New maxrtc(4) driver for the Maxim DS1307 real time clock.
[*] New nvme(4) driver for the Non-Volatile Memory Express (NVMe) host controller interface.
[*] New pcfrtc(4) driver for the NXP PCF8523 real time clock.
[*] New umb(4) driver for the Mobile Broadband Interface Model (MBIM).
[*] New ure(4) driver for RealTek RTL8152 based 10/100 USB Ethernet devices.
[*] New utvfu(4) driver for audio/video capture devices based on the Fushicai USBTV007.
[*]
The iwm(4) driver now supports Intel Wireless 3165 and 8260 devices, and works more>
[*] Support for I2C HID devices with GPIO signalled interrupts has been added to dwiic(4).
[*]
Support for larger bus>
[*] Support for EHCI and OHCI compliant USB controllers on Octeon II SoCs.
[*] Many USB device drivers have been enabled on OpenBSD/octeon.
[*] Improved support for hardware-reduced ACPI implementations.
[*] Improved support for ACPI 5.0 implementations.
[*] AES-NI crypto is now done without holding the kernel lock.
[*] Improved AGP support on PowerPC G5 machines.
[*] Added support for the SD card slot in Intel Bay Trail SoCs.
[*] The ichiic(4) driver now ignores the SMBALERT# interrupt to prevent an interrupt storm with buggy BIOS implementations.
[*] Device attachment problems with the axen(4) driver have been fixed.
[*] The ral(4) driver is more stable under load with RT2860 devices.
[*] Problems with dead keyboards after resume have been fixed in the pckbd(4) driver.
[*] The rtsx(4) driver now supports RTS522A devices.
[*] Initial support for MSI-X has been added.
[*] Support MSI-X in the virtio(4) driver.
[*] Added a workaround for hardware DMA overruns to the dc(4) driver.
[*] The acpitz(4) driver now spins the fan down after cooling if ACPI uses hysteresis for active cooling.
[*] The xhci(4) driver now performs handoff from an xHCI-capable BIOS correctly.
[*] Support for multi-touch input has been added to the wsmouse(4) driver.
[*] The uslcom(4) driver now supports the serial console of Aruba 7xxx wireless controllers.
[*] The re(4) driver now works around broken LED configurations in APU1 EEPROMs.
[*] The ehci(4) driver now works around problems with ATI USB controllers (e.g. SB700).
[*] The xen(4) driver now supports domU configuration under Qubes OS.
