Xa sithetha ngeLinux, into yokuqala ethi qatha engqondweni kwabaninzi sisiphelo sendlela, kodwa nokhuseleko. Nangona kungekho nkqubo yokusebenza igqibeleleyo, indlela esebenza ngayo ipenguin yokusebenza kweemvume yenza ukuba ubunzima bube nzima ukuxhaphaza. Kodwa yonke into inokuphucula, ukhuseleko lubandakanyiwe, kunye neLinux 5.4 iya kubandakanya imodyuli entsha yokhuseleko abayibizileyo Ukutshixa.
I-Linus Torvalds yamkele inqaku ngoMgqibelo odlulileyo, emva kokuba belilungiselelwe ingxoxo-mpikiswano iminyaka eliqela. Imodyuli izakufika kwiLinux 5.4, Inguqulelo yekernel ngoku efumana izicelo zomsebenzi, kodwa iya kukhubazeka ngokungagqibekanga. Iya kuba yi-LSM (Imodyuli yoLondolozo lweLinux okanye imodyuli yokhuseleko yeLinux) kwaye isigqibo sokungasebenzi ngokungagqibekanga senziwe kuba utshintsho lunokubangela ukuba inkqubo yokusebenza ingasebenzi.
Ukutshixeka kuya kukhubazeka ngokungagqibekanga kwiLinux 5.4
La Umsebenzi ophambili Ukutshixa kuya komeleza ukwahlula phakathi kweenkqubo zomsebenzisi kunye nekhowudi yekernel Ukuthintela iakhawunti yomlawuli ekusebenzisaneni nekhowudi yekernel I-Linux, into enokwenziwa ukuza kuthi ga ngoku. I-LSM entsha iya kuthintela eminye imisebenzi yekernel, ukuthintela iingxelo zeengcambu ekubeni zonakalise yonke inkqubo yokusebenza. Phakathi kwezinye izinto, iLockdown iya kuthintela ukufikelela kwimisebenzi yekernel evumela ukwenziwa ngokungafanelekanga kwekhowudi ebonelelwe yinkqubo yomsebenzisi, iya kutshixa iinkqubo ekubeni ikwazi ukufunda / ukubhala kwiimemori / dev / mem y / dev / kmem kunye nokufikelela kuvulo / i-dev / izibuko.
Kuya kubakho iindlela ezimbini zokutshixa: "ukuthembeka" kunye "nokugcinwa kuyimfihlo", nganye nganye yahlukile kwaye ithintela ukufikelela kwimisebenzi eyahlukeneyo ye-kernel:
Ukuba imiselwe kwingqibelelo, imisebenzi yekernel evumela ilizwe lomsebenzisi ukuba litshintshe i-kernel ikhubaziwe. Ukuba isetelwe kwimfihlo, imisebenzi yekernel evumela indawo yomsebenzisi ukuba ikhuphe ulwazi kwi-kernel ikhubazekile.
Eli linyathelo elibalulekileyo kwindlela yokwenza iLinux ikhuseleke nangakumbi, enye ibisoloko ixoxwa ukusukela ngo-2010. ukusukela ngo-Epreli 2020 Masipapashe iindaba ezingaphantsi ezinxulumene neebugs zokhuseleko ezilungiswe ngombulelo weCanonical kwinto eya kubakho ngoDisemba.
