Ngexesha leentsuku ezimbalwa ezidlulileyo kwimeko yamanyathelo athathwe liqela labaphandi Ukusuka kwiYunivesithi yaseMinnesota, ukusukela ngokwembono yabaninzi, ezo zenzo ngokunxulumene nokwaziswa kokuchaphazeleka kwi-Linux Kernel ayinasizathu.
Kwaye nangona liqela Abaphandi beYunivesithi yaseMinnesotukupapasha ileta evulekileyo yokucela uxolo, Ukwamkela utshintsho kwiKernel kernel eyayivalwe UGreg Kroah-Hartman utyhile iinkcukacha Amachaphaza angeniswe kubaphuhlisi be-kernel kunye nembalelwano nabalondolozi abanxulunyaniswa nezi patches.
Kuyaphawuleka ukuba zonke iipatches ezingafunekiyo zaliwe Kwiphulo labalondolozi, akukho nanye kwiipatches eyamkelweyo. Le nyaniso iyenza icace gca ukuba kutheni uGreg Kroah-Hartman enze ubukrakra ngolu hlobo, njengoko kungacacanga ukuba abaphandi ngekhe benze ntoni ukuba ezi patches zivunyiwe ngumlondolozi.
Ekuqwalaseleni kwakhona, bathi bazimisele ukuxela le bug kwaye abanakuzivumela ii-patches ukuba ziye kwi-Git, kodwa akucaci ukuba baya kwenza ntoni na okanye bangaya kude kangakanani.
Lilonke, ngo-Agasti ka-2020, iziqwengana ezintlanu zathunyelwa zivela kwiidilesi ezingaziwa acostag.ubuntu@gmail.com kunye jameslouisebond@gmail.com (ileta evela kuJames Bond): ezimbini zichanekile kwaye zintathu kubandakanya iimpazamo ezifihliweyo, ukudala iimeko zokubonakala kwe Ukuba semngciphekweni.
Isiqwenga ngasinye sinemigca emi-1 ukuya kwemine yekhowudi. Olona luvo luphambili lweepatches ezimbi yayikukuba ukulungisa ukuvuza kwenkumbulo kunokudala imeko yokuba sesichengeni simahla kabini.
Iprojekthi ijolise ekuphuculeni ukhuseleko lwenkqubo yokudibanisa kwi-OSS. Njengengxenye yeprojekthi, sifunda iingxaki ezinokubakho ngenkqubo yokupakisha ye-OSS, kubandakanya oonobangela beengxaki kunye neengcebiso zokujongana nazo.
Ngapha koko, olu phononongo lutyhila ezinye iingxaki, kodwa injongo yalo kukufuna iinzame zokuphucula
Inkqubo yokupakisha ukukhuthaza umsebenzi omninzi ukuphuhlisa iindlela zokuvavanya kunye nokuqinisekisa iipatches, kwaye ekugqibeleni ukwenza i-OS ikhuseleke ngakumbi.Ngokusekwe kwezi patches, sishwankathela iipateni zabo, sifunde izizathu ezithile zokuba kutheni kunzima ukungenisa iigciwane (kunye nohlalutyo lomgangatho kunye nobungakanani), kwaye okona kubaluleke kakhulu kukubonelela ngeziphakamiso zokujongana nengxaki.
Isiziba sokuqala esinengxaki silungisa ukuvuza kwenkumbulo ngokongeza umnxeba kwi-kfree () ngaphambi kokubuyisa ulawulo kwimeko yempazamo, kodwa ukudala iimeko zokufikelela kwindawo yememori emva kokuba ikhululwe (sebenzisa-emva kokukhululeka).
Isiziba esichaziweyo saliwe ngumlondolozi, ochonge ingxaki kwaye wabonisa ukuba kunyaka ophelileyo umntu ebesele ezama ukucebisa utshintsho olufanayo kwaye lwamkelwa ekuqaleni, kodwa walahla kwangolo suku lunye emva kokuchonga iimeko zokuba sesichengeni.
Isiziba sesibini sikwakuqulathe iimeko zokukhutshwa kokukhutshwa emva kokukhutshwa. Isicatshulwa esikhankanyiweyo asamkelwanga ngumlondolozi, osikhabileyo isikhewu ngenxa yenye ingxaki nge list_add_tail, kodwa khange aqaphele ukuba isikhombisi se "chdev" sinokukhululeka kwi-put_device function, esetyenziswa ngokulandelayo kwifowuni eya ku-dev_err (& chdev -> dev ..). Nangona kunjalo, isiziba asamkelwanga, nangona kungenxa yezizathu ezingahambelani nokuba sesichengeni.
Okumangalisayo kukuba Ekuqaleni bekucingelwa ukuba ii-4 kwezi-5 zeepatch zineengxaki, kodwa abaphandi ngokwabo benza impazamo nakwisiqwengana esinengxaki, ngokoluvo lwabo, kwenziwa isisombululo esichanekileyo, ngaphandle kweemeko zokuba basebenzise imemori emva kokumiliselwa.
Kulo msebenzi, sinika umxholo we «ukuba semngciphekweni kokungakhuli kakuhle» apho imeko yokuba sesichengeni isilela, kodwa inokuba yinto yokwenyani xa imeko ingekho
yaziswa ngesiqwenga sesinye ibug.Sikwavelisa izixhobo ezisinceda ukuba sifumane iindawo zekhowudi ezinokuthi zisokole
yeencindi zokungeniswa kwe-bug kwaye ucebise ukuba yintoni enokwenza ukuba ezi ziqulatho ze-bug zingenze kube nzima ukuzibona.Kwiveki kamva, ulwazi lwathunyelwa kubaphuhlisi be-kernel ngesindululo sokuxoxa malunga nokuba kunokwenzeka kokukhuthaza ubungozi phantsi kokuzilungisa okungenamsebenzi kokuvuza kwenkumbulo, kodwa akukho nto yathethwayo malunga nemizamo yangaphambili yokungenisa ii-patches ezinobungozi.
Isiqwenga sesithathu sakhatywa ngumlondolozi ngenxa yesinye isiphazamiso ngaphandle komngcipheko (isicelo esiphindwe kabini kwi-pdev).
