Inguqulelo entsha yeLinux Kernel 4.20 sele ikhutshiwe

Zimbalwa iiyure ezidlulileyo kwaye Emva kweenyanga ezimbini zophuhliso, uLinus Torvalds wabhengeza ingxelo entsha yeLinux Kernel 4.20.

Oko phakathi olona tshintsho lubalulekileyo kule nguqulo intsha yeKernel 4.20 Izinto ezintsha zibandakanyiwe, apho izilungiso ezahlukeneyo zongezwe ngokweempazamo kwaye, ngaphezulu kwako konke, inkxaso yezixhobo ezahlukeneyo.

Kule nguqulo intsha yeLinux Kernel Iipatches ezingama-14,997 zenziwe ukusuka kubaphuhlisi abali-1857 ukuya kwinguqulelo entsha, Ubungakanani bepatch yayingu-49MB (utshintsho oluchaphazele iifayile ezili-11,402, imigca engama-686,104 yekhowudi yongezwa, imigca engama-318945 isusiwe).

Phantse iipesenti ezingama-47 zazo zonke iinguqu ezichazwe kwi-4.20 zinxulumene nabaqhubi bezixhobo, malunga ne-17% yotshintsho inxulumene nokuhlaziya ikhowudi ethile yoyilo lwehardware, i-14% inxulumene nesitaki senethiwekhi, iipesenti ezi-3 ziinkqubo zeefayile kunye neepesenti ezi-4 Iinkqubo zangaphakathi zekernel.

Yintoni eNtsha kwiLinux Kernel 4.20?

Ngale nto intsha ikhutshiweyo, inkxaso kwi-C-SKY yoyilo loyilo yongezwa kunye neshedyuli yendlela ye-taprio, i-PSI (ulwazi olunqanda uxinzelelo), i-P2P DMA ye-PCI.

Ngaphandle kwantonie yongeze ikhowudi yokulungisa uphawu, Unxibelelwano lwe-cache network transmission dissectors kulwakhiwo olutsha lwe-XArray, ukudibanisa i-amdgpu kunye nabaqhubi be-amdkfd, ukwandisa ukusebenza kwenkqubo esezantsi ye-FUSE, ukukwazi ukucoca iipakethi zenethiwekhi ngokusekwe kwiimpawu zecmarkmark, ukuvumela ubunyani be-KVM.

I-speck ihambile

Isikhalazo esinempikiswano kutshanje esongezwe ngeLinux 4.17 kwi-Kernel encryption algorithm yasuswa kwiLinux 4.20.

Kuba uGoogle wahlutha ukuthembela kwekhowudi ye-Android eyenzelwe oko. Oku kwakungekho ngenxa yetekhnoloji, njengoko ialgorithm yaphuhliswa yi-NSA.

Kwaye ukubekwa emgangathweni koku kwaliwe, njengoko i-NSA yayingathandi ukuphendula imibuzo eneenkcukacha malunga nealgorithm.

Kwakhona, ubuchule buye bonyuswa nge-KVM, ngoku eyenza ukuba oomatshini bokwenyani basebenze ngokuchanekileyo kumatshini oqinisekileyo.

Inkxaso ikwakhona kwiRaspberry Pi Model 3. Kwixesha elizayo, isitaki seTCP siza kuzisa iipakethi nge-algorithm entsha, ekungafuneki ukuba ikhawuleze kuphela kodwa ikhuseleke ngakumbi.

Iinkqubo ezintsha

Ishedyuli entsha "yethrafri" yezithuthi yenziwa kule kernel, evumela ukulawula ukuthunyelwa kweepakethi ngokolandelelwano lwamaxesha aveliswe ngaphambili.

Indlela yokucwangciswa ichaziwe kwinkcazo ye-IEEE 802.1Qbv, ithathela ingqalelo iimfuno zokuhambisa ixesha elinovakalelo lokuhanjiswa kwepakethi (umzekelo, imijelo yevidiyo nevidiyo), kwaye isebenzisa amaxesha ahlukeneyo eeklasi ezahlukeneyo zendlela.

Kwiprotocol ye-rtnetlink, imo yokujonga engqongqo iyenziwa ("Ukutshekishwa kanzima"), okuqinisekisa ukuba ulwazi olufanelekileyo ludluliselwa kwindawo yomsebenzisi ehambelana nesicelo esingenayo;

Yongeze amandla okucoca inkunkuma ngolwazi lokuhamba ngomgaqo osetyenzisiweyo (umzekelo, ukwahlula iindlela kwiidemon ezihamba ngeendlela ezahlukeneyo), iintlobo zeendlela (umzekelo, ukwabela i-unicast)

Isazisi setafile yendlela kunye nesango elikufutshane (nexthop).

Ezo zihluzo kudala zaxhaswa kwi-iproute2, kodwa zaphunyezwa kwindawo yomsebenzisi. Ukuhambisa iifilitha kwisithuba se-kernel kukuvumela ukuba wandise ukusebenza kweenkqubo ezinkulu zendlela esekwe kwiLinux.

Kumiliselo lweebhulorho zenethiwekhi (isiseko senkqubo yokuvala), amandla okujonga amanani eVLAN kwimeko yamazibuko ngamanye ongeziwe;

Inkxaso yamajelo ama-5 kunye nama-6 ebhendi ye-60 GHz yongezwa kwi-ieee80211 isitaki esingenacingo, kunye nesakhono sokwenza ukuba umphenduli weFTM asebenze kwindawo yomsebenzisi.

Kwaye iKernel 5.0 yeyiphi?

Ekugqibeleni, abaninzi balindele ukuba i-kernel entsha iya kufana notshintsho oluye kwi-4.0 ukusukela emva kokuba kulindelwe u-4.19 u-5.0.

Nangona kunjalo, kuba iTorvalds ayifuni ukulungiswa kwisikimu, kwathiwa iLinux 5.0 iza kuza ngo-2019. Nangona umhla oqikelelweyo ungaziwa, kuba okwangoku izicwangciso zenguqulo elandelayo ziyaqhubeka kwinguqulo 4.21.
