Imininingwane yeKernel 4.6

Kusuka ku-2015 kuya onyakeni wamanje sithole izibuyekezo eziyisikhombisa noma izinhlobo ezintsha ze-Linux kernel. Ukusuka kunguqulo 3.19, kuye ku-4.5. Njengoba bekulindelekile, ngaloyo nyaka kwakumele sihlangane nokunye ukuthuthukisa umnyombo, kwaba njalo. Kulenyanga sanikezwa uhlelo olusha lwe-Linux kernel, kungu-4.6 edition wayo. Lokhu kuyatholakala kusuka ngoMeyi 15, futhi kungeza ezinye izindaba ngesakhiwo noma okuqukethwe.

Sekukonke sithola ukuphatha okuthembekile okungaphandle kwememori, ukwesekwa kwe-USB 3.1 SuperSpeedPlus, ukwesekwa kokhiye bokuvikela imemori ye-Intel, KANYE nohlelo olusha lwefayela le-OrangeFS oluhanjiswa, ukubala nje okumbalwa. Kepha ngokuningiliziwe, amaphuzu abaluleke kakhulu okuxoxwe ngawo ku-kernel yilezi ezilandelayo:

• Ukuthembeka kuphume enkumbulweni.
• Ukuxhumeka kwe-Kernel multiplexer.

• Ukusekelwa kwe-USB 3.1 SuperSpeedPlus.

• Ukusekelwa kokhiye bokuvikela inkumbulo ye-Intel.

• Uhlelo lwefayela olusatshalaliswa i-OrangeFS.

• Ukusekelwa kwenguqulo V ye-BATMAN protocol.

• Ukubethela kweleveli ye-802.1AE MAC.

• Faka ukusekelwa kwesakhiwo se-pNFS SCSI

• dma-buf: ioctl entsha yokuphatha ukungaguquguquki kwe-cache phakathi kwe-CPU ne-GPU.

• Isihloli se-inode se-OCFS2 online

• Ukusekelwa kwezikhala zamagama eqembu

Ukuthembeka kuphume enkumbulweni.

Umbulali we-OOM ezinhlotsheni ezedlule wayenenhloso yokuqeda umsebenzi, ngethemba lokuthi lo msebenzi waqedwa ngesikhathi esamukelekayo nokuthi imemori yayizokhululwa ngemuva kwalokhu. Kukhonjisiwe ukuthi kulula ukubona ukuthi imithwalo yemisebenzi eyephula leyo nkolelo ikuphi, nokuthi isisulu se-OOM singaba nesikhathi esingenamkhawulo sokuphuma. Njengesilinganiso salokhu, kunguqulo ye-kernel 4.6, a umabhebhana njengomucu wekernel okhethekile, ozama ukubuyisa inkumbulo, okungukuthi, ukushintshanisa impahla yesisulu se-OOM ngaphandle, noma isilinganiso sokuvikela imemori engaziwa. Konke kungaphansi komqondo wokuthi le nkumbulo ngeke idingeke.

Ukuxhumeka kwe-Kernel multiplexer.

Isikhungo se-multiplexer kernel sinikeza isikhombimsebenzisi esincike emiyalezweni nge-TCP, ngenhloso yokusheshisa imigomo yesendlalelo sohlelo lokusebenza. I-kernel yokuxhuma ye-multiplexer, noma i-KCM yesifinyezo sayo, ifakiwe kulolu hlobo. Ngenxa yenhlamvu yokuxhuma ye-multiplexer, uhlelo lokusebenza lungathola kahle futhi luthumele imiyalezo yohlelo lokusebenza nge-TCP. Ngaphezu kwalokho, i-kernel inikeza iziqinisekiso zokuthi imilayezo ithunyelwa futhi yamukelwe nge-athomu. Ngakolunye uhlangothi, i-kernel isebenzisa umhleli womlayezo osuselwa ku-BPF, konke ngenhloso yokuthi imilayezo ebhekiswe esiteshini se-TCP ingamukelwa ku-kernel yokuxhuma ye-multiplexer. Kuyafaneleka ukusho ukuthi i-kernel yokuxhuma ye-multiplexer ingasetshenziswa enombolweni enkulu yezinhlelo zokusebenza, ngoba iningi lamaphrothokholi wohlelo lokusebenza kanambambili asebenza ngaphansi kwale nqubo yokuhlaziya imilayezo.

Ukusekelwa kwe-USB 3.1 SuperSpeedPlus (10 Gbps).

Okwe-USB 3.1 kufakwa umthetho olandelwayo omusha; yena I-SuperSpeedPlus. Lokhu kuyakwazi ukuxhasa isivinini se-10 Gbps. Kubandakanya ukuxhaswa kwe-USB 3.1 kernel kanye ne-USB xHCI host controller, ehlanganisa isitoreji esikhulu, ngenxa yokuxhumeka kwe-USB 3.1 ethekwini le-USB 3.1 elikwazi ukusingatha i-xHCI. Kuyaphawuleka ukuthi amadivayisi we-USB asetshenziselwe inqubo entsha ye-SuperSpeedPlus abizwa nge-USB 3.1 Gen2 amadivayisi.

Ukusekelwa kokhiye bokuvikela inkumbulo ye-Intel.

Lokhu kusekelwa kufakwa esicini esithile, kukhulunywa ngokukhethekile ngehadiwe kanye nokuvikelwa kwayo kwememori. Lesi sici sizotholakala kuma-Intel CPU alandelayo; okhiye bokuvikela. Lezi zinkinobho zivumela ukufakwa ekhompyutheni kwamaski wemvume alawulwa ngumsebenzisi, atholakala kokufakiwe kwetafula lekhasi. Sikhulume ngalokho esikhundleni sokuba nesifihla-buso sokuvikela esimisiwe, esidinga ukushayelwa kohlelo ukuze sishintshe futhi sisebenze ekhasini ngalinye, manje umsebenzisi anganikeza inani elihlukile lokuhluka njengemaski yokuvikela. Ngokuqondene nesikhala somsebenzisi, angakwazi ukuphatha inkinga yokufinyelela kalula ngerejista yasendaweni yemicu, esatshalaliswa izingxenye ezimbili kumaskhi ngamunye; kukhubaza ukufinyelela nokukhubaza ukubhala. Ngalesi siyakuqonda ukuba khona noma ukuthi kungenzeka kushintshwe ngokunamandla izingcezu zokuvikela zememori enkulu, kuphela ngokuphathwa kwerejista ye-CPU, ngaphandle kwesidingo sokushintsha ikhasi ngalinye endaweni yememori ebonakalayo ethintekayo.

Uhlelo lwefayela olusatshalaliswa i-OrangeFS.

Kuyisistimu yesitoreji esilinganayo ye-LGPL noma esikalini. Isetshenziselwa kakhulu izinkinga ezikhona maqondana nokugcinwa okuphathwa ku-HPC, Big Data, ukusakazwa kwevidiyo noma i-Bioinformatics. Nge-OrangeFS ingatholakala ngemitapo yolwazi yokuhlanganisa abasebenzisi, izinsiza zohlelo ezifakiwe, i-MPI-IO futhi ingasetshenziswa imvelo yeHadoop njengenye indlela yohlelo lwefayela le-HDFS.

I-OrangeFS ayidingeki ngokujwayelekile ukuze izicelo zifakwe ku-VFS, kepha iklayenti eliyinhloko le-OrangeFS lenzeka linikeze izinhlelo zamafayela amandla okufakwa njenge-VFS.

Ukusekelwa kwenguqulo V ye-BATMAN protocol.

I-BATMAN (Indlela Engcono Ye-Mobile Adhoc Networking) noma i-ORDINANCE. (Indlela engcono yamanethiwekhi wesikhashana wezikhangiso) Lesi sikhathi sifaka ukwesekwa kweprotocol V, njengengxenye yeprotocol IV. Njengenye yezinguquko ezibaluleke kakhulu ku-BATMA.NV yi-metric entsha, ekhombisa ukuthi umthetho olandelwayo ngeke usancika ekulahlekelweni kwepakethe. Lokhu futhi kuhlukanisa umthetho olandelwayo we-OGM ube izingxenye ezimbili; Owokuqala yi-ELP (Echo Location Protocol), ophethe ukuhlola ikhwalithi yesixhumanisi nokuthola omakhelwane. Futhi eyesibili, umthetho olandelwayo omusha we-OGM, i-OGMv2, efaka i-algorithm ebala imizila efaneleke kakhulu futhi enweba imethrikhi ngaphakathi kwenethiwekhi.

Ukubethela kweleveli ye-802.1AE MAC.

Ukusekelwa kwe-IEEE MACsec 802.1A, indinganiso enikeza ukubethela ngaphezulu kwe-Ethernet, kungezwe kulokhu kukhishwa. Ibhala ngemfihlo iphinde ifakazele wonke umgwaqo ku-LAN nge-GCM-AES-128. Ngaphezu kwalokho, vikela i-DHCP ne-VLAN traffic, ukuze ukukhohlisa kwezihloko ze-ethernet kugwenywe. Idizayinelwe ukuphatha ukhiye wokunweba we-MACsec protocol, ohlanganisa ukusatshalaliswa kwezikhiye kuma-node nokwabiwa kweziteshi.

Lezi ezinye zezici ezithuthukisiwe kunguqulo entsha ye-Linux kernel. Uyabona ukuthi kube nokuthuthuka okukhulu kwezokuphepha. Okubonakalayo kwizisekeli ezintsha ezinamathiselwe amaCore Components, ngokugcizelelwa okuningi ekwehliseni amaphutha. Phakathi kwezici zayo eziningi ezimbozwe le nguqulo engu-4.6, abathuthukisi bayo baqinisekisa ukuthi kungakuhle ukuthi izinhlelo ezihlotshaniswa ne-Linux kernel zingabuyekezwa ngokuzenzakalela, kubhekiswe kubasabalalisi beLinux ne-Android. Okuthile okubaluleke kakhulu kulezi zinhlelo, ngoba le nguqulo entsha ivelele, ezicini eziningi, njengenguqulo ephephe kunazo zonke ye-kernel.

Okunye ukuthuthukiswa kwezokuphepha ukuthi iLinux manje isebenzisa amakhasi ahlukene we-Extensible Firmware Interface (EFI) lapho isebenzisa ikhodi yayo ye-firmware. Ibuye futhi isebenzisane nabaprosesa be-IBM Power9 futhi manje iLinux inokusekelwa okungaphezulu kwezinhlelo ze-13 ARM kuma-chips (SOC) kanye nokuxhaswa okungcono okungama-64-bit ARM.

Ngakolunye uhlangothi, i-kernel 4.6 nayo isekela umthetho olandelwayo we-Synaptics RMI4; Le yiphrothokholi yendabuko yazo zonke izikrini zokuthinta zamanje ze-Synaptics namaphhedi okuthinta. Ekugcineni, ukusekelwa kwamanye amadivayisi we-interface womuntu nakho kuyangezwa.

I-Linux kernel ikhombisa ukuqina okuya ngokuya ngokuya ngokuphepha. Okuthile okunenzuzo futhi lokho kudala ukuzethemba kubasebenzisi abahlotshaniswa nalesi simiso njalo. Uma ufuna imininingwane eminingi ngenguqulo entsha, ungafinyelela ekhasini elisemthethweni le-Linux kernel futhi ufunde ngezinguquko.
