Linus Torvalds k\u00ebrkoi nga administratori i kernel.org q\u00eb t\u00eb bllokonte menj\u00ebher\u00eb llogarin\u00eb e Kesa Kuk, ish-administratorit kryesor t\u00eb kernel.org dhe liderit t\u00eb Ubuntu Security Team, i cili mbante n\u00eb b\u00ebrtham\u00eb 14 n\u00ebn-sisteme t\u00eb lidhura me sigurin\u00eb. Konstantin Ryabtsev, p\u00ebrgjegj\u00ebs p\u00ebr infrastruktur\u00ebn e kernel.org, e realizoi bllokimin. Shkaku i bllokimit ishte nj\u00eb pull request p\u00ebr t\u00eb p\u00ebrfshir\u00eb n\u00eb deg\u00ebn e b\u00ebrtham\u00ebs 6.16 ndryshime q\u00eb referoheshin n\u00eb nj\u00eb git-repozitor, ku ishte ndryshuar informacioni mbi autor\u00ebsin\u00eb e disa komiteteve. <\/p>\n
N\u00eb depozit\u00ebn git t\u00eb mb\u00ebshtetur nga Kesa, kishte modifikime fikse, n\u00eb fushat e autorit dhe komiterit t\u00eb cilave u ishte cituar \"Linus Torvalds\", por Linus nuk i kishte shtuar ato. P\u00ebr shembull, n\u00ebn emrin e Linusit n\u00eb deg\u00ebn e Kes\u00ebs kishte nj\u00eb komit q\u00eb p\u00ebrs\u00ebriste nj\u00eb komit tjet\u00ebr n\u00eb deg\u00ebn e Linusit, por me nj\u00eb hash t\u00eb ndrysh\u00ebm SHA1. T\u00eb dyja komitet duken identike, p\u00ebrve\u00e7 informacionit t\u00eb n\u00ebnshkrimit. <\/p>\n
Modifikimet nuk duken si nj\u00eb gabim t\u00eb rast\u00ebsish\u00ebm gjat\u00eb ekzekutimit t\u00eb operacionit \"git rebase\", pasi p\u00ebrmbanin informacion t\u00eb pav\u00ebrtet\u00eb mbi autorin e komitit. Linus Torvalds e konsideroi k\u00ebt\u00eb si shenja t\u00eb nj\u00eb aktiviteti potencialisht t\u00eb d\u00ebmsh\u00ebm dhe inicioi bllokimin e pranuar t\u00eb \u00e7do modifikimi nga Kesa, deri n\u00eb sqarimin e arsyeve t\u00eb atyre manipulimeve dhe konfirmimin se sistemi i Kes\u00ebs nuk ishte komprometuar. <\/p>\n
Kesa u p\u00ebrgjigj se nuk kupton se si mund t\u00eb kishte ndodhur di\u00e7ka e till\u00eb. P\u00ebrpara k\u00ebsaj, kishte hasur probleme kur p\u00ebrpiqej t\u00eb bashkonte disa nga deg\u00ebt e tij git, pas s\u00eb cil\u00ebs p\u00ebrpiqej t\u2019i zgjidhte ato me operacionin \"git rebase\", por duket se kjo nuk ndihmoi. E gjith\u00eb kjo ndodhte n\u00eb kontekstin e nj\u00eb d\u00ebshtimi t\u00eb SSD-s\u00eb, e cila po jepte gabime gjat\u00eb kopjimit. Kesa mendonte se pas d\u00ebshtimit kishte arritur t\u00eb rikthente gjendjen e depozitave t\u00eb tij, por duke u dukur kjo nuk ishte e v\u00ebrtet\u00eb. P\u00ebr t\u00eb rikthyer integritetin, Kesa planifikon t\u00eb rimarr\u00eb deg\u00ebt e tij nga patches t\u00eb ve\u00e7anta. Si arsye m\u00eb e mundshme p\u00ebr nd\u00ebrrimin e autorit, Kesa beson se \u00ebsht\u00eb nj\u00eb p\u00ebrpjekje e d\u00ebshtuar p\u00ebr t\u00eb rikuperuar depozit\u00ebn pas d\u00ebmtimit t\u00eb saj. <\/p>\n
Linusi nuk ishte i k\u00ebnaqur me k\u00ebt\u00eb shpjegim, pasi, sipas tij, ndryshimet e historis\u00eb s\u00eb komiteteve n\u00eb depozit\u00ebn e Kes\u00ebs duken shum\u00eb si veprime t\u00eb q\u00ebllimshme, dhe jo si nj\u00eb d\u00ebshtim t\u00eb rast\u00ebsish\u00ebm. Rimbazimi i historis\u00eb s\u00eb ndryshimeve me operacionin \"git rebase\" mund t\u00eb shpjegonte mbivendosjen e komiterit, por Linusi nuk mund ta kuptoj\u00eb se si nj\u00eb operacion \"git rebase\" mund t\u00eb ishte kryer aksidentalisht. <\/p>\n
Rewriting one or two commits could still be attributed to an error, but more than six thousand merge commits were rewritten in Kess's repository, out of which Linus was listed as the author in 330, despite the fact that these commits were not obtained from Linus's git tree. The changes made resemble the work of a script more than the result of information damage on the storage device, as they require separately recreating a copy of each commit. <\/p>\n
Kes e siguroi Linusin se nuk e kishte b\u00ebr\u00eb k\u00ebt\u00eb q\u00ebllimisht dhe nuk do t\u00eb kryente eksperimente t\u00eb tilla pa paralajm\u00ebrim (p\u00ebr shembull, eksperimenti i kaluar mbi thyerjet e komiteteve ishte miratuar nga Linusi). K\u00ebt\u00eb jav\u00eb, ai ka kryer disa operacione manuale me repositorin dhe tani do t\u00eb p\u00ebrpiqet t\u00eb kuptoj\u00eb se \u00e7far\u00eb shkoi keq dhe t\u00eb riprodhonte problemin. P\u00ebr shembull, Kes kryente operacionin rebase p\u00ebr deg\u00ebt git for-next\/hardening dhe for-linus\/hardening, duke p\u00ebrdorur, ndryshe nga transformimet e m\u00ebparshme, deg\u00ebn \u00abmaster\u00bb, n\u00eb vend t\u00eb rc2. Gjat\u00eb k\u00ebtij operacioni ai ndryshoi skriptet p\u00ebr t\u00eb verifikuar k\u00ebrkesat e push-it. <\/p>\n
