Ubuntu amakonza zolakwika zitatu zachitetezo pazosintha zaposachedwa za kernel

Ndasintha Ubuntu 20.04 kernel

Wogwiritsa ntchito aliyense wapakati pa Ubuntu amadziwa kuti amamasula mtundu watsopano wa makina ogwiritsira ntchito miyezi isanu ndi umodzi iliyonse, kuti zaka ziwiri zilizonse pamakhala mtundu wa LTS, komanso kuti kernel imatha kutenga nthawi yayitali kuti isinthe. M'malo mwake, ikatero, imatero m'mitundu ya LTS ngati sititsatira njira zingapo monga zomwe zili mu nkhaniyi ya momwe mungasungire ku Focal Fossa. Chowonadi ndi chakuti kernel imasinthidwa, koma kuwonjezera zigamba zachitetezo monga achitira mitundu yonse ya Ubuntu zomwe tsopano zikuthandizidwa.

Maola angapo apitawo, Canonical idasindikizidwa malipoti atatu a USN, makamaka Kutumiza & Malipiro, Kutumiza & Malipiro y Kutumiza & Malipiro. Yoyamba imakhudza mitundu yonse ya Ubuntu yomwe imathandizirabe, yomwe ndi Ubuntu 22.04 yomwe yatulutsidwa posachedwapa, mtundu wokhawo womwe sunathandizidwe ndi LTS, womwe ndi 21.10, kenako 18.04 ndi 16.04, womwe umathandizidwa chifukwa cholowa gawo lake la ESM. , zomwe zimalola kuti apitirize kulandira zigamba zachitetezo.

Ubuntu imasintha kernel yake kuti ikhale yotetezeka

Pofotokoza za USN-5443-1, timawerenga zolephera ziwiri:

(1)Kukonzekera kwa netiweki ya Linux kernel ndi kachitidwe ka mizere sikunachite kuwerengera molondola nthawi zina, zomwe zimapangitsa kuti pakhale chiopsezo chogwiritsa ntchito pambuyo pake. Wowukira mdera lanu atha kugwiritsa ntchito izi kuletsa ntchito (kusokonekera kwadongosolo) kapena kupereka makhodi osavomerezeka. (2) Linux kernel sinali kukakamiza zoletsa za seccomp moyenera nthawi zina. Wowukira mdera lanu atha kugwiritsa ntchito izi kuti alambalale zoletsa zomwe akufuna. 

Za USN-5442-1, zomwe zimangokhudza 20.04 ndi 18.04, nsikidzi zina zitatu:

(1) Network Queuing and Scheduling subsystem ya Linux kernel sinachite kuwerengera molondola nthawi zina, zomwe zimapangitsa kuti pakhale chiopsezo chogwiritsa ntchito pambuyo pake. Wowukira mdera lanu atha kugwiritsa ntchito izi kuletsa ntchito (kusokonekera kwadongosolo) kapena kupereka makhodi osavomerezeka. (2) Dongosolo laling'ono la io_uring la kernel ya Linux linali ndi kusefukira kwathunthu. Wachiwembu wakomweko atha kuyigwiritsa ntchito kuletsa ntchito (kuwonongeka kwadongosolo) kapena kupereka makhodi osavomerezeka. (3) Linux kernel sinali kukakamiza zoletsa za seccomp moyenera nthawi zina. Wowukira mdera lanu atha kugwiritsa ntchito izi kuti alambalale zoletsa zomwe akufuna.

Ndipo za USN-5444-1, zomwe zimakhudza Ubuntu 22.04 ndi 20.04;

Ma Network Queuing and Scheduling subsystem a Linux kernel sanachite kuwerengera molondola nthawi zina, zomwe zimapangitsa kuti pakhale chiopsezo chogwiritsa ntchito pambuyo pake. Wowukira mdera lanu atha kugwiritsa ntchito izi kuletsa ntchito (kusokonekera kwadongosolo) kapena kupereka makhodi osavomerezeka.

Kuti mupewe mavuto onsewa, chinthu chokhacho chomwe chiyenera kuchitika ndikuwongolera kernel, ndipo izi zitha kuchitika zosintha zokha ndi chida chosinthira za kukoma kulikonse kovomerezeka kwa Ubuntu. Apanso, kumbukirani kuti ndikofunikira kukhala ndi makina ogwiritsira ntchito nthawi zonse, makamaka ndi zigamba zaposachedwa zachitetezo.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
