Ungazi kanjani ukuthi Ubuntu bethu busengozini yeMeltdown naseSpecter

Okuthiwa yi-Intelagate kuyaqhubeka nokuba khona kumakhompyutha nakumakhompyutha amaningi, Ubuntu noma bungekho. Ukuba sengozini okungathinti kuphela amakhompyutha anama-processor we-Intel kepha futhi namakhompyutha anama-processor we-AMD ne-ARM. Kuyathakazelisa ukuthi abasebenzisi be-Ubuntu abanayo le nkinga kuphela kepha futhi nenkinga ye-Ubuntu 17.10 kernel, ngakho-ke ukuhlanganisa i-kernel ye-Ubuntu kuba ngumsebenzi oyisidina.

Ngakho-ke siya sitshele ukuthi wazi kanjani ukuthi ngabe ikhompyutha yethu ye-Ubuntu isengozini noma cha kwi-Meltdown ne-Specter, amagama okukhubazeka kwe-Intel. Uma sesisebenzise le ndlela sizokwazi uma kufanele sisebenzise isixazululo esihlongozwayo noma singaqhubeka njengoba sasinjalo ngaphandle kokunciphisa ijubane imishini yethu.

Ngiyabonga unjiniyela uStéphane Lesimple singathola ukuthi ngabe sisengozini yeSpecter noma cha ngokusebenzisa nje iskripthi. Singawuthola lo mbhalo ngokusebenzisa i- I-Lesimple Official Github futhi lapho silanda ifayela, silisebenzisa njengezimpande ngokulandelayo:

sudo su sh ./spectre-meltdown-checker.sh

Iskripthi sizohlola ukuthi sengozini noma cha futhi uma sinjalo, sizositshela nge-terminal. Uma ngeshwa sibuthaka, kufanele buyekeza wonke amashayeli ahlobene ne-CPU futhi uvuselele i-Ubuntu 17.10 kernel noma uhlanganise eyakho lapho i-retpoline ingahlanganiswa.

Njengoba i-Meltdown ne-Specter kuyizimbungulu ezimbili ezithinta i-Hardware, lezi zokugcina ngeke zanele futhi kuzofanele sikwenze buyekeza uhlelo ngezikhathi ezithile ukuze kube nezinguquko zakamuva maqondana nalokhu. Umsebenzi ozokwenza Ubuntu bethu buphephe kepha futhi buhambe kancane, into ecasulayo kumaqembu anezinsizakusebenza ezilinganiselwe. Kunoma ikuphi, kubonakala sengathi i-Ubuntu 17.10 kernel ihloselwe ukushintshwa njalo Awucabangi?
