Inguqulo entsha yeLinux Kernel 4.20 isivele ikhishiwe

Ambalwa amahora edlule futhi Ngemuva kwezinyanga ezimbili zokuthuthuka, uLinus Torvalds umemezele inguqulo entsha yeLinux Kernel 4.20.

Lokho phakathi izinguquko eziphawuleka kakhulu kule nguqulo entsha yeKernel 4.20 Izici ezintsha zifakiwe, lapho kungezwe ukulungiswa okuhlukahlukene ngokuya ngamaphutha futhi, ngaphezu kwakho konke, ukusekelwa kwamadivayisi ahlukahlukene.

Kule nguqulo entsha yeLinux Kernel Ama-patches we-14,997 enziwe kusuka konjiniyela be-1857 kuya enguqulweni entsha, usayizi wepatch ubuyi-49MB (izinguquko zithinte amafayela ayi-11,402 686,104, imigqa yekhodi engu-318945 ingeziwe, kususwe imigqa engama-XNUMX).

Cishe u-47% wazo zonke izinguquko ezethulwe ku-4.20 zihlobene nezishayeli zedivayisi, cishe u-17% wezinguquko uhlobene nokubuyekeza ikhodi ethile yezakhiwo zehadiwe, i-14% ihlobene nesitaki senethiwekhi, i-3% yizinhlelo zamafayela kuthi i-4% ibe izinhlelo ezingaphansi ze-kernel.

Yini okusha in Linux Kernel 4.20?

Ngalokhu kukhishwa okusha, ukusekelwa kokwakhiwa kweprosesa le-C-SKY ingezwe kanye neshejuli yethrafikhi ye-taprio, isistimu esezingeni eliphansi ye-PSI (imininingwane evimba ingcindezi), i-P2P DMA ye-PCI.

Ngaphandle kwalokhoe ingeze ikhodi yokucubungula isignali, ukuxhumeka kwama-cache network transmission dissectors esakhiweni esisha se-XArray, kuhlanganiswa amdgpu kanye nabashayeli be-amdkfd, kukhulisa ukusebenza kohlelo olungaphansi lwe-FUSE, ikhono lokuhluza amaphakethe enethiwekhi ngokususelwa kumathegi we-secmark, avumela ukubonwa okuhle kwe-KVM.

Ispekhi sihambile

I-Speck enempikiswano esanda kungezwa neLinux 4.17 ku-Kernel encryption algorithm isusiwe ku-Linux 4.20.

Njengoba i-Google inciphise ukwethenjwa kwekhodi ye-Android ehlose empeleni. Lokhu kwakungabangelwa ubuchwepheshe, njengoba i-algorithm yathuthukiswa yi-NSA.

Futhi ukuqiniswa kwalokhu kwenqatshiwe, njengoba i-NSA yayingathandi ukuphendula imibuzo enemininingwane mayelana ne-algorithm.

Futhi, i-virtualization ithuthukisiwe nge-KVM, manje enika amandla imishini ebonakalayo ngokwenza okuhle okwenziwe ngomshini obonakalayo.

Ukusekelwa kuyatholakala nakwi-Raspberry Pi Model 3. Ngokuzayo, isitaki se-TCP sizoletha amaphakethe nge-algorithm entsha, okungafanele isheshe kuphela kepha futhi ivikeleke kakhulu.

Izivumelwano ezintsha

Isheduli yethrafikhi entsha ye- "taprio" yenziwe kule kernel, evumela ukuphatha ukuthunyelwa kwamaphakethe ngokochungechunge lwesikhathi esenziwe ngaphambili.

Indlela yokuhlela ichazwa kusichasiso se-IEEE 802.1Qbv, ibheka nezidingo zokudlulisa ithrafikhi ebucayi besikhathi sokulethwa kwamaphakethe (ngokwesibonelo, ukusakazwa kwevidiyo nomsindo), futhi isebenzisa izikhala zezikhathi ezahlukahlukene zezigaba ezihlukile zethrafikhi.

Ngephrothokholi ye-rtnetlink, kusetshenziswa imodi eqinile yokuhlola ("Ukuhlolwa kanzima"), okuqinisekisa ukuthi imininingwane efanele idluliselwa esikhaleni somsebenzisi esihambisana nesicelo esingenayo;

Kungezwe ikhono lokuhlunga izilahla ngolwazi lomzila ngamaphrothokholi asetshenzisiwe (ngokwesibonelo, ukuhlukanisa imizila kusuka kumademoni ahlukile womzila), izinhlobo zemizila (ngokwesibonelo, ukwabela i-unicast)

I-ID yetafula lokuhambisa umzila nesango eliseduzane (nexthop).

Izihlungi ezinjalo sekuyisikhathi eside zisekelwa ku-iproute2, kepha zenziwa esikhaleni somsebenzisi. Ukuhambisa izihlungi esikhaleni se-kernel kukuvumela ukuthi wandise ukusebenza kahle kwezinhlelo ezinkulu zomzila we-Linux.

Ekuqalisweni kokuvaleka kwenethiwekhi (ukuvala uhlelo olungaphansi), amandla wokuhlola izibalo ze-VLAN kumongo wamachweba ngamanye engeziwe;

Ukusekelwa kweziteshi ezi-5 no-6 zebhendi le-60 GHz kungezwe kwisitaki esingenantambo se-ieee80211, kanye nokukwazi ukunika amandla ukusebenza kwe-FTM Responder kusuka esikhaleni somsebenzisi.

Futhi iKernel 5.0 yenzelwe nini?

Ekugcineni, abaningi balindele ukuthi i-kernel entsha izofana noshintsho olungu-4.0 ngoba ngemuva kwengu-4.19 ingu-5.0 manje kulindelwe.

Kodwa-ke, njengoba iTorvalds ingafuni ukulungiswa esikimini, kwathiwa iLinux 5.0 izofika ngo-2019. Yize usuku olulinganiselwayo lungaziwa, ngoba okwamanje izinhlelo zenguqulo elandelayo ziyaqhubeka zenguqulo 4.21.
