Utsleppet av den fritt tilgjengelige plattformuavhengige UNIX-liknende operativsystemet OpenBSD 6.9 er n\u00e5 lansert. Dette markerer den 50. utgivelsen av prosjektet, som i \u00e5r fyller 26 \u00e5r. OpenBSD-prosjektet ble grunnlagt av Theo de Raadt i 1995 etter en konflikt med utviklerne av NetBSD, som resulterte i at Theo mistet tilgangen til CVS-repositoriet til NetBSD. Etter dette skapte Theo de Raadt sammen med en gruppe likestilte en ny \u00e5pen kildekode-operativsystem basert p\u00e5 kildekode-treet til NetBSD, med hovedm\u00e5lene for utviklingen som portabilitet (st\u00f8tter 13 maskinvareplattformer), standardisering, korrekt drift, aktiv sikkerhet og integrerte kryptografiske midler. St\u00f8rrelsen p\u00e5 det komplette installasjons-ISO-bildet av basisversjonen av OpenBSD 6.9 er 544 MB. <\/p>\n
I tillegg til det operativsystemet, er OpenBSD-prosjektet kjent for sine komponenter som har blitt utbredt i andre systemer og har etablert seg som noen av de sikreste og mest kvalitetsbevisste l\u00f8sningene. Blant dem finner vi: LibreSSL (en fork av OpenSSL), OpenSSH, pakkefilteret PF, rutingdemonene OpenBGPD og OpenOSPFD, NTP-serveren OpenNTPD, e-postserveren OpenSMTPD, tekstterminalmultiplexeren (tilsvarende GNU screen) tmux, identd-demon med implementasjon av IDENT-protokollen, BSDL-alternativet til GNU groff-pakken \u2013 mandoc, protokoll for organisering av feilfrie systemer CARP (Common Address Redundancy Protocol), en lettvekts http-server, og verkt\u00f8yet for filsynkronisering OpenRSYNC. <\/p>\n
Hovedforbedringer: <\/p>\n
\n
Softraid-driveren har f\u00e5tt en RAID1C-modus med implementering av programvare-RAID1 med datakryptering.\n
To the setup are included two new background processes \u2014 dhcpleased and resolvd, which work together with slaacd and unwind for automatic configuration of network interfaces and DNS name resolution. The dhcpleased implements the DHCP protocol for obtaining IP addresses, while resolvd manages the contents of resolv.conf based on information about name servers received from dhcpleased, slaacd, and drivers like umb.\n
Innledende st\u00f8tte for Apple-enheter med M1-prosessor er lagt til. Dette inkluderer gjenkjenning av Apple Icestorm\/Firestorm arm64-kjerner og st\u00f8tte for BCM4378 tr\u00e5dl\u00f8se brikker som brukes i Apple M1 SoC.\n
St\u00f8tten for powerpc64-plattformen, utviklet for 64-bits systemer basert p\u00e5 POWER8- og POWER9-prosessorer, er forbedret. Sammenlignet med den forrige utgivelsen er st\u00f8tten for RETGUARD-beskyttelsesmekanismen implementert for powerpc64, en astfb-driver for Aspeed BMC framebuffer er lagt til, problemer med radeondrm- og amdgpu-driverne p\u00e5 systemer med AMD GPU er l\u00f8st, muligheten for nettverksoppstart er lagt til i kjernebyggingen for ramdisk, st\u00f8tte for str\u00f8msparemodus for CPU POWER9 er lagt til, samt st\u00f8tte for unntak generert under flyttalloperasjoner, og IPMI-st\u00f8tte for PowerNV-systemer er implementert.\n
For ARM64 platforms, support for CPU Cortex-A78AE, Cortex-X1, and Neoverse V1 has been implemented, providing optimized ARM64 versions of copyin, copyout, and kcopy calls, along with the addition of the cryptox driver for support of ARMv8 crypto extensions and the smmu driver for RM System MMU with Guard Page support. Improved support for Raspberry Pi, Rock Pi N10, NanoPi, and Pinebook Pro devices.\n
In the video driver, a sysctl parameter kern.video.record has been added, which, similar to kern.audio.record, controls the enabling of an empty frame output when attempting to capture video (to allow video capture, the value must be changed to 1). Processes are allowed to open the video device multiple times (which resolves issues with using webcams in Firefox and BigBlueButton).\n
Tracing points have been added for malloc and free calls, allowing the tracking of memory allocation activity using dt and btrace. An option '-n' has been added to btrace for parsing the program without performing any actions.\n
Support for multiprocessor systems (SMP) has been enhanced. The implementation of UNIX sockets has been extracted from the global kernel lock, a shared mutex for serializing operations with msgbuf has been added, the uvm_pagealloc call has been made mp-safe, and the 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, support for DRI3 has been established in both amdgpu and ati drivers, and device creation in the directory \/dev\/dri\/ has been implemented for compatibility with Linux.\n
Improvements have been made in the VMM hypervisor. Support for booting from compressed RAM disks has been added to the backend for managing virtual machines vmd.\n
Improvements have been made to the sound subsystem. The ability to separately configure sound devices sndio for playback only and record only has been provided. A low-pass filter with finite impulse response (FIR-filter) of eighth order has been implemented in sndiod, eliminating noise due to spectral overlap during resampling. By default, the automatic volume reduction feature when a new program starts playback (autovolume) is disabled, with a default volume level set to 127. Mixing sound from alternative devices with different supported functionality in sndiod is now allowed.\n
Debugging and installation of LLDB is enabled by default.\n
Support for the logger handler has been added in rcctl, rc.subr, and rc.d, allowing for the organization of log output from background processes that send data to stdout\/stderr.\n
Touchpads now allow configuration of button layouts through wsconsctl. wscons has improved handling of simultaneous touches.\n
For ARM64 devices, support for using APM to obtain power consumption and battery charge data has been implemented. The unveil call has been employed to limit access of the apmd process to the filesystem.\n
Hardware support has been expanded. New drivers acpige (for handling ACPI events such as power button presses), pchgpio (for GPIO controllers found in modern Intel PCH), ujoy (for game controllers), uhidpp (for Logitech HID++ devices) have been added. Support for AMD Vi and Intel VTD IOMMU extensions for PCI device isolation and blocking improper memory access has been implemented. Support for Lynloong LM9002\/9003 and LM9013 computers has been added. The pcamux and imxiic drivers have been extended to support ACPI.\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, support for RA (802.11n Tx Rate Adaptation) has been added. The wireless stack has been configured to automatically select modes 11a\/b\/g\/n\/ac when using the network interface in access point mode.\n
