The release of the free cross-platform UNIX-like operating system OpenBSD 6.9 has been announced. It is noted that this is the 50th release of the project, which will celebrate its 26th anniversary this year. The OpenBSD project was founded by Theo de Raadt in 1995 after a conflict with the NetBSD developers, which resulted in Theo being denied access to the CVS repository of NetBSD. Following this, Theo de Raadt and a group of like-minded individuals created a new open operating system based on the NetBSD source tree, with primary development goals of portability (supporting 13 hardware platforms), standardization, correctness, active security, and integrated cryptographic tools. The size of the full installation ISO image of the OpenBSD 6.9 base system is 544 MB. <\/p>\n
In addition to the operating system itself, the OpenBSD project is known for its components, which have gained popularity in other systems and have established themselves as some of the safest and highest-quality solutions. Among them are: LibreSSL (a fork of OpenSSL), OpenSSH, the packet filter PF, the routing daemons OpenBGPD and OpenOSPFD, the NTP server OpenNTPD, the email server OpenSMTPD, the terminal multiplexer (similar to GNU screen) tmux, the identd daemon implementing the IDENT protocol, the BSDL alternative to the GNU groff package \u2014 mandoc, the protocol for organizing fault-tolerant systems CARP (Common Address Redundancy Protocol), and a lightweight HTTP server along with the OpenRSYNC file synchronization utility. <\/p>\n
Key Improvements: <\/p>\n
\n
The softraid driver has added a RAID1C mode with the implementation of software RAID1 with data encryption.\n
The composition includes two new background processes \u2014 dhcpleased and resolvd, which work alongside slaacd and unwind for automatic network interface configuration and DNS name resolution. The dhcpleased implements the DHCP protocol for obtaining IP addresses, while resolvd manages the contents of resolv.conf based on data from name servers provided by dhcpleased, slaacd, and drivers like umb.\n
Initial support for Apple devices with the M1 processor has been added. This includes recognition of the Apple Icestorm\/Firestorm arm64 cores and support for the BCM4378 wireless chips used in the Apple M1 SoC.\n
Support for the powerpc64 platform has been improved, developed for 64-bit systems based on POWER8 and POWER9 processors. Compared to the previous release, support for the RETGUARD protection mechanism has been implemented for powerpc64, an astfb driver has been added for the Aspeed BMC framebuffer, issues with radeondrm and amdgpu drivers on AMD GPU systems have been resolved, network boot capability has been added to the kernel builds for ram disks, support for CPU POWER9 power-saving modes has been provided, support for exceptions generated during floating-point operations has been added, and IPMI support for PowerNV systems has been implemented.\n
Support for ARM64 platforms has been provided for CPU Cortex-A78AE, Cortex-X1, and Neoverse V1, with optimized ARM64 versions of copyin, copyout, and kcopy calls implemented, a cryptox driver added for ARMv8 crypto extensions support, and a smmu driver for RM System MMU with Guard Page support. Improved support for Raspberry Pi, Rock Pi N10, NanoPi, and Pinebook Pro devices.\n
The video driver has been updated with the sysctl parameter kern.video.record, which, like kern.audio.record, controls the inclusion of an empty image output when attempting to capture video (for capture resolution, the value must be set to 1). Processes are now allowed to open the video device multiple times (resolving issues with using webcams in Firefox and BigBlueButton).\n
Tracing points for malloc and free calls have been added, allowing memory allocation activity to be monitored using dt and btrace. The btrace has introduced the '\u2013n' option for parsing a program without performing any actions.\n
Support for multiprocessor systems (SMP) has been enhanced. The implementation of UNIX sockets has been removed from the global kernel lock, a common mutex has been added for serializing operations with msgbuf, the uvm_pagealloc call has been made mp-safe, and getppid and sendsyslog calls have been freed from locks.\n
Issues in the DRM (Direct Rendering Manager) components have been fixed, including crashes in the radeondrm driver on Powerbook5\/6 and RV350 systems. DRI3 support has been established in the amdgpu and ati drivers, and device creation in the \/dev\/dri\/ directory has been implemented for Linux compatibility.\n
Improvements have been made to the VMM hypervisor. The backend for managing virtual machines, vmd, now supports booting from compressed RAM disks.\n
Enhancements have been made to the audio subsystem. It is now possible to dedicate sndio sound devices solely for playback or recording. The sndiod now features an eighth-order finite impulse response (FIR) low-pass filter, which has eliminated noise caused by spectrum overlap during resampling. By default, the automatic volume reduction function when a new program starts playback (autovolume) is disabled, with the default volume level set to 127. Mixing sound from alternative devices with differing levels of supported functionality in sndiod has been enabled.\n
The LLDB debugger build and installation is enabled by default.\n
Support for the logger handler has been added to rcctl, rc.subr, and rc.d, allowing for organizing log output from background processes sending data to stdout\/stderr.\n
Touchpads now allow button layout configuration via wsconsctl. Concurrent touch handling has been improved in wscons.\n
APM support for obtaining power consumption and battery charge data has been implemented for ARM64 devices. An unveil call is used to restrict the apmd process's access to the filesystem.\n
Hardware support has been expanded. New drivers acpige (for handling ACPI events like power button presses), pchgpio (for GPIO controllers found in modern Intel PCH), ujoy (for game controllers), and uhidpp (for Logitech HID++ devices) have been added. Support for AMD Vi and Intel VTD IOMMU extensions for isolating PCI devices and blocking improper memory access has also been added. Support for Lynloong LM9002\/9003 and LM9013 computers has been introduced. ACPI support has been added to the pcamux and imxiic drivers.\n
Network adapter support has been improved: mvpp (SFP+ and 10G for Marvel Armada Ethernet), mvneta (1000base-x and 2500base-x), mvsw (Marvel SOHO switches), rge (Wake on LAN support), Netgear ProSecure UTM25. For wireless drivers iwm, iwn, and athn, RA (802.11n Tx Rate Adaptation) support has been added. The wireless stack has been set up for automatic mode selection 11a\/b\/g\/n\/ac when using a network interface as an access point.\n
A veb (Virtual Ethernet Bridge) driver has been implemented in the network stack. Monitoring mode is now supported, where incoming packets on the network interface are not passed to the network stack for processing, but traffic analysis mechanisms such as BPF can be applied to them. A new type of network interface \u2014 etherbridge \u2014 has been added. The ability (route sourceaddr command) to override the source has been provided. an IP address<\/a> Automatic activation of network interfaces is provided when entering autoconfiguration mode (AUTOCONF4 and AUTOCONF6).\n
