Akuthathanga xesha lide ukuba sipapashe umfanekiso ofana nowangaphambili. Ncnci kakhulu. Hayi neeyure ezingama-24. Sidla ngokubeka into enje xa kukho isiphene sokhuseleko kwinkqubo yokusebenza, kwaye Ubuntu 19.10 bufika ne kernel equlethe ibug enokuthi ivumele ukwenziwa kwekhowudi ngokungenamkhethe. Ukusuka kwinkangeleko yayo, i-OS yakhululwa ngaphandle kokubandakanya isiqwenga esele silungisiwe, ngoko ke kufuneka sifumane uhlaziyo lokuqala lwe-kernel kunye nengxelo ehambelana ne-USN.
Igciwane lifunyenwe ngumfundi we Phoronix, oqinisekisa kwakhona ukuba i bug kwikhowudi yekernel ye IPv6 kunokukhokelela ekukhanyeni kwenkonzo (DoS) okanye ukuphunyezwa kwekhowudi engafanelekanga. Kwakhona, kwaye bekukho ezininzi mva nje, lixesha elifanelekileyo lokukhumbula ukuba iLinux 5.4 iya kubandakanya imodyuli entsha yokhuseleko abayibizileyo. Ukutshixa kwaye oko kuya kunceda ukuphepha iingxaki zolu hlobo, kunye nexabiso lokuhlawula esiya kuphulukana nolawulo kwizixhobo zethu.
ICanonical ukukhupha uhlaziyo lwekernel kungekudala
Umsebenzisi ofumene ibug ukwasibonisa indlela yokuvavanya ibug, ekufuneka siyivavanye sebenzisa isiqwengana esilandelayo njengaye nawuphi na umsebenzisi:
susa ukwabelana -rUn sh -c 'ikhonkco le-ip yongeza i-dummy1 uhlobo lwe-dummy && ikhonkco le-ip seta i-dummy1 phezulu && ip -6 indlela yongeza idev dummy1 && ip -6 umthetho wongeza itafile engundoqo suppress_prefixlength 0 && ping -f 1234::1'
Ukuba siyachaphazeleka, inkqubo yethu iya konakala. Kodwa, njengezinambuzane ezininzi kwi-Ubuntu kernel kunye nezinye izinikezelo zeLinux, ukuze sisebenzise le bug kufuneka sibe nayo. ukufikelela ngokomzimba kwizixhobo.
Kucacile ukuba inkampani efana neCanonical kufuneka idibane ne-ajenda kwaye ilibazise ukuqaliswa kwe U-Eoan Ermine ngenxa yokungaphumeleli okudinga ukufikelela ngokomzimba kwisixhobo kwakungekho khetho. Kwiiyure / iintsuku ezimbalwa ezizayo kufuneka kubekho uhlaziyo kwiziko lethu lesoftware elilungisayo. Xa ixesha lifikile, siya kukwazisa.
