Kulezi zikhathi, lapho sikhuluma ngento ehlobene nobuchwepheshe, sivame ukukhuluma ezinyangeni ngaphambi kokuthi kwenzeke okuthile. Njengamanje, amasistimu amaningi okusebenza awakavuseleli i-kernel yabo enguqulweni 5.xx futhi sesivele sinezindaba ezihlobene ne- Linux 5.2. Njengezinombolo zezinqubo kuFirefox 66, izindaba esikulethela zona namuhla zizoba zinhle kumakhompyutha amaningi, kodwa kwabanye ngeke kube njalo.
Futhi ingabe leyo Linux 5.2 yenza kusebenze inketho ye-Live Patching ye-GCC 9, umhlanganisi ngenxa yokuthi uzokhishwa emasontweni ambalwa ezayo. Le inketho eyenzelwe ukusiza ukukhiqiza ama-binaries asebenza kahle ukuze i-Live Patching isebenze. Ngokufika kwe-Linux kernel v5.2, le nketho izosetshenziswa ngokuzenzakalela, okungadala ukwehla kwejubane. Akufanele ukuthi ibonakale, noma ihle ngisho nakumakhompyutha amasha, kepha kungaba yinkinga kumadivayisi anqunyelwe izinsiza.
I-Linux 5.2 izosebenza i-Live Patching ngokuzenzakalela
I-GCC 9 yethula Izinketho ezi-5 zokuchibiyela okulawula ukuthi yikuphi ukusetshenziswa okuhle okusetshenziselwa ukuzama nokuqinisekisa ukuthi akukho nhlekelele eyenzekayo uma i-kanambambili ingafaka izibuyekezo zokuphepha ze-kernel ngaphandle kwesidingo sokuqalisa kabusha. Lokhu kubalulekile ezimweni ezifana ne-kGraft, Ksplice neKpatch ukusiza ukuqinisekisa ukuthi umhlanganisi we-GCC akawushintshi umsebenzi wakho we- "live patch".
I-GCC 9.1.0 izokhishwa ngokuhamba kwesikhathi kule nyanga noma vele ngoMeyi. Ekugcineni, iLinux 5.2 izokwenza kusebenze izinhlobo ezi-5 zePatch Live ngokwakhona lapho isebenza kusihlanganisi esisekelwayo nalapho CONFIG_LIVEPATCH iyasebenza, okuthile kuzoba kanjena ngokuzenzakalela kuzinhlamvu eziningi ze-Linux. NguMiroslav Benes, ovela kwaSUSE kanye nomuntu ophethe ushintsho, oxwayisa lokho kwezinye izimo ezingavamile kungaba nomthelela omubi ekusebenzeni njengomphumela wale nketho "bukhoma bukhoma" elawula ukusebenza kwe-compiler optimization.
Futhi ngukuthi, yize singakuthandi, lokhu kuvame ukufana nalokhu: uma sifuna ukujabulela imisebenzi emisha, kuzodingeka ukuthi silahlekelwe okuthile, futhi lokhu kubonakala kakhulu ekusetshenzisweni kwebhethri kwama-smartphones. Ucabanga ukuthi le nketho inikwe amandla ngokuzenzakalela ku-Linux 5.2?
