OpenBSD ndeye yakakwana, yemahara, muchinjika-chikuva Unix-senge yekushandisa system yakavakirwa paBSD.
The kuburitswa kweiyo vhezheni itsva yeiyo yakakurumbira UNIX OS, "OpenBSD 7.3" kupfuura iyo yese yekushandisa system pachayo, iyo OpenBSD purojekiti iri inozivikanwa nokuda kwezvikamu zvayo, izvo zvave zvakapararira mune mamwe maitiro uye vakaratidza kuva imwe yakachengeteka uye yepamusoro-soro mhinduro.
Pazvinhu zvitsva zvinoratidzwa mushanduro itsva yeOpenBSD 7.3, zvinomira pachena waitid system inofona yaitwa (kumirira shanduko yemamiriro ezvinhu), pinsyscall (kupfuudza ruzivo nezve Executive yekupinda nzvimbo yekudzivirira kubva kuROP maitiro), getthrname uye setthrname (tora uye uise zita reshinda).
Ese magadzirirwo anoshandisa clockintr, hardware-yakazvimirira timer kukanganisa scheduler.
Yakawedzerwa sysctl kern.autoconf_serial, iyo inogona kushandiswa kutarisa mudziyo wemuti mamiriro shanduko mukernel kubva munzvimbo yemushandisi.
Imwe yeshanduko dzakaratidzwa mushanduro itsva ndeyekuti dzakaitwa maficha ekuwedzera kuchengetedza kwe process memory munzvimbo yemushandisi: iyo isingachinjike system yekufona uye yakabatana raibhurari basa rezita rimwe chete, iro rinokutendera iwe kugadzirisa kodzero dzekuwana kana dzichiratidzwa mundangariro (memory kugoverwa).
Mushure mekupinza, kodzero dzakagadzirirwa nzvimbo yekurangarira, semuenzaniso, kurambidzwa kunyora nekuita, hakugone kuchinjwa kuburikidza nekufona kunotevera mmap (), mprotect () uye munmap () mabasa, ayo, kana achiedza kuchinja, ichagadzira EPERM kukanganisa.
OpenBSD 7.3 zvakare inosimbisa iyo yakavandudzwa rutsigiro rwemasisitimu multiprocessor (SMP). Iwo mafirita echiitiko etun uye tap zvishandiso akashandurwa kuita mp-yakachengeteka, pamwe nekuvharira mupf packet sefa yakagadziridzwa uye zvakare yakagadziridzwa sisitimu uye network stack performance pane multicore masisitimu.
Iyo yakawedzera rutsigiro rwemhando nyowani dzeRyzen 7xxx GPU , pamwe nerutsigiro rwakawedzerwa rwekudzora mwenje webacklight muamdgpu uye yakaita xbacklight kushanda kana uchishandisa mode configuration X.Org mutyairi. Mesa ine shader caching inogoneswa neiyo default.
Ukuwo Kudzivirirwa kwekushandisa kunogoneswa zvichibva pakusungirirwa kwe sshd inogoneka pane imwe neimwe system boot. Kuvhara zvakare kunoita kuti zviome kufanotaura zvigadziriso zvekushanda mu sshd, izvo zvinoita kuti zviome kugadzira mashandisiro anoshandisa maitiro ekudzokera-anotungamirwa ekuronga.
Pane dzimwe shanduko dzinobuda pachena:
- Kuvandudzwa kwakaitwa kuVMM hypervisor.
- Kuitwa kwegadziriro drm (Direct Rendering Manager) iri kuwiriraniswa neLinux kernel 6.1.15 (5.15.69 mune yapfuura shanduro).
- Pane iyo AMD64 yekuvakisa, iyo RETGUARD yekudzivirira nzira inogoneswa kufona system, chinangwa chayo chiri kuomesera mabatiro akagadzirwa nekodhi snippets uye kudzoka-yakatarisana programming maitiro.
- Yakawedzera hukasha stack nzvimbo randomization pane 64-bit masisitimu.
- Yakawedzerwa dziviriro kubva kuSpecter-BHB kusagadzikana mune processor microarchitecture zvimiro.
- PaArM64 processors, iyo DIT (Data Yakazvimirira Nguva) mureza inogoneswa kuti mushandisi-nzvimbo uye kernel-nzvimbo yekuvhara parutivi-chiteshi kurwiswa kunonyengedza kutsamira kweiyo nguva yekumhanya pane data rakagadziriswa mumirairo iyi.
- Inopa kugona kushandisa lladdr kana uchitsanangura network masisitimu. Semuenzaniso, kunze kwekusungira kune zita rekushandisa, unogona zvakare kusunga kune kero yeMAC.
- Yakavandudzwa hibernation rutsigiro rweARM64 yakavakirwa masisitimu.
- Yakawedzera tsigiro yeApple ARM chips.
- Yakawedzera rutsigiro rwe Hardware nyowani uye yaisanganisira vatyairi vatsva.
- Iyo bwfm mutyairi wemakadhi asina waya akavakirwa paBroadcom neCypress machipisi anoisa encryption rutsigiro rweWEP.
- Iyo yekuisa yakavandudza basa nesoftware RAID uye yakashandisa yekutanga tsigiro ye Guided Disk Encryption.
- Yakawedzera mirairo mitsva yekumusoro neyepasi ku tmux ("multiplexer terminal") kukwenya chituru kumusoro nekudzika.
- Yakagadziridzwa LibreSSL uye OpenSSH mapakeji.
Pakupedzisira yeiyo kuda kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo mu chinotevera chinongedzo.
Dhawunirodha uye tora OpenBSD 7.3
Kune avo vanofarira kukwanisa kuwana iyo vhezheni itsva, vanofanirwa kuziva kuti saizi yekuisa yakazara ISO mufananidzo weiyo base system. OpenBSD 7.3 ndeye 620MB.
