Zimbalwa izinsuku ezedlule kwenzeke isigameko esingajwayelekile, eyanyakazisa umphakathi we-Linux kernel, futhi lokho U-Linus Torvalds uyalele ukumiswa ngokushesha kwe-akhawunti ka-Kees Cook ku-kernel.org., ngemva kokuthola ukuba khona kwezibopho eziguquliwe kule ndawo ye-Git kanjiniyela.
Kees Cook, waziwa ngobuholi bakhe eqenjini lezokuphepha le-Ubuntu kanye nokugcina amasistimu angaphansi kwe-kernel ahlobene nokuphepha, uye wavinjelwa okwesikhashana ukuhambisa izinguquko ngesikhathi amaqiniso esacaciswa.
Ukuguqulwa kobunikazi namasignesha endaweni yokugcina yase-Kees Cook
Inkinga ivele esicelweni sokushintsha sokufakwa.s egatsheni le-kernel engu-6.16, lapho uLinus ehlonze khona izinkomba zendawo obekuqukethwe wenza okhohlisiwe nge igama lakhe njengombhali nomqinisekisi, nakuba engazange azenze yena ngokwakhe. Esinye sezibonelo ezibucayi kwakuwukuba khona kwesibopho esiyimpinda, okufanayo kokuqukethwe nesoqobo kodwa esine-SHA1 hashi ehlukile, efake ngokungeyikho isiginesha ka-Linus Torvalds.
Lezi zinguquko angeke kubalulwe nje iphutha lengozil ngesikhathi sokusebenza kabusha kwe-git, ngoba zibandakanya ukuguqulwa okukhulu yolwazi olubucayi, okuhlanganisa nezibophezelo ezibhalwe kabusha ezingaphezu kuka-6.000, ezingu-330 zazo ezazinegama likaLinus njengombhali.
Ukusabela kukaTorvalds: izinsolo zokukhohlisa ngamabomu
ULinus Torvalds akazange akufihle ukukhathazeka kwakhe futhi ichaze izehlakalo njengeziyingozi kakhulu:
"Oyedwa noma ababili ababhale kabusha kungaba yiphutha. Kodwa izinkulungwane zabo, abaningi abanesiginesha yami engumgunyathi, azilona," esho.
Uma kubhekwa ubukhulu bezinguquko kanye nobungozi bobuqotho besihlahla se-kernel esisemthethweni, UTorvalds wabuza uKonstantin Ryabitsev, umlawuli wengqalasizinda we-kernel.org, qukuvimba ukufinyelela kuka-Kees Cook kuze kube yilapho isimo sesicacisiwe.
Ukuphendula, U-Kees Cook wachaza ukuthi ubenezinkinga zobuchwepheshe zakamuva lokho bekungadala isigameko. Wathi, Idrayivu yakho ye-SSD ibe namaphutha ngesikhathi sokukopisha, okubangele ukonakala kumakhosombe amaningana. Ngemuva kwalawa maphutha, uzame ukubuyisa isimo sendawo yakhe yokugcina esebenzisa i-git rebase namathuluzi ahlukahlukene wokuzenzakalela.
Nokho, le misebenzi yenziwa emagatsheni abucayi, njengokulandelayo/ukuqina kanye ne-linus/ukuqina, okuholele ekulungisweni ngephutha komlando wenqolobane, okuhlanganisa noshintsho ekugunyazweni kwezibopho. Naphezu kwencazelo yakhe, uLinus wayenokungabaza.:
"Angiqondi ukuthi kungenzeka kanjani ukudlula ngephutha, ingasaphathwa eyezinguquko eziningi."
Umlandu wangempela: i-git-filter-repo nama-trailer e-b4
Emlayezweni wakamuva, U-Kees Cook uhlonze okungenzeka kube umthombo wephutha: ukusetshenziswa okuhlangene kwamathuluzi amabili, I-git-filter-repo kanye nama-trailer e-b4, akhohlisa umlando wokuzibophezela kanye nama-trailer (amathegi afana nokuthi Kusayinwe-ngo-:) ekuzinikeleni.
Lokhu kusetshenziswa okungalungile yenzuzo bekungabangela ukubhalwa kabusha okuzenzakalelayo kwezinkulungwane zezibopho, okuhlanganisa ukufaka esikhundleni sombhali ivelu ezenzakalelayo (kulokhu, uLinus Torvalds), ngaphandle kokuthi uKees ebona iphutha ngaleso sikhathiUKonstantin Ryabitsev, umbhali wethuluzi le-b4, uqinisekise lo mbono futhi wagomela ukuthi kwakungekho nhloso embi engxenyeni kaCook. Eqinisweni, uhlelo beseluvele lukhiqiza izexwayiso ebezinganakwa.
Ngemva kokucaciswa kwesimo, ukufinyelela kuka-Kees Cook ku-kernel.org kwabuyiselwa. Njengendlela yokuvimbela, kumenyezelwe ukuthi ithuluzi b4 izofaka isheke elisha lokuvikela, Lokhu kuzovimbela ukuguqulwa kwezibopho ubunikazi bazo obungahambisani nobunikazi bomsebenzisi wamanje kusukela manje kuqhubeke. Lokhu kuhloselwe ukuvimbela amaphutha afanayo nokuvikela ubuqotho bekhodi yomthombo we-kernel.
UKees yena uthembise ukuthi uzowakha kabusha amagatsha athintekile. kusuka kumapeshi angawodwana futhi uhlaziye ngokujulile izinyathelo eziholele ephutheni. Nakuba Lesi sigameko sihlehlise ubudlelwano eqenjini ukuthuthukiswa kwe-kernel, kuphinde kwagqamisa ukubaluleka kokusebenzisa amathuluzi okubhala kabusha umlando ngokuqapha, ikakhulukazi kumaphrojekthi abaluleke kakhulu njenge-Linux kernel.
Okokugcina, kufanelekile ukusho ukuthi lesi sigameko phakathi kukaLinus Torvalds noKees Cook siyisixwayiso mayelana nezingozi zokukhohlisa umlando wokuzibophezela nokuthi. sibonga ukungenelela okusheshayo kusuka kulabo ababhekele i-kernel.org kanye nokuba sobala kwenqubo, isimo sesilawulwa.
Okokugcina, uma ungathanda ukufunda okwengeziwe ngakho, ungabheka imininingwane kokulandelayo isixhumanisi
