Kernel 4.6 ruzivo

Kubva 2015 kusvika gore razvino tawana zvinomwe zvinowedzeredzwa kana shanduro nyowani dzeLinux kernel. Kuenda kubva mushanduro 3.19, kusvika ku4.5. Sezvakatarisirwa, kusvika gore iro isu taifanirwa kusangana neimwe yekuvandudza iyo musimboti, uye yaive. Yatove yemwedzi uno uchienderera takapihwa new edition yeLinux kernel, mune yayo edition 4.6. Izvi zvinowanikwa kubva muna Chivabvu 15, uye zvinowedzera dzimwe nhau dzechimiro kana zvemukati.

Pakazara tinowana yakavimbika kunze-kwe-ndangariro kubata, tsigiro ye USB 3.1 SuperSpeedPlus, tsigiro yeIntel memory kuchengetedza makiyi, Uye iyo nyowani OrangeFS yakagovera faira system, kungo taura mashoma. Asi mune zvakadzama, iwo akakosha mapoinzi akakurukurwa pamusoro peiyo kernel aive anotevera:

• Kuvimbika kunze kwendangariro.
• Kernel multiplexer kubatana.

• Tsigiro ye USB 3.1 SuperSpeedPlus.

• Tsigiro yeIntel memory kuchengetedza makiyi.

• OrangeFS Yakagoverwa Faira Sisitimu.

• Tsigiro yeshanduro V yeBATMAN protocol.

• 802.1AE MAC level encryption.

• Wedzera rutsigiro rwePNFS SCSI dhizaini

• dma-buf: ioctl nyowani yekugadzirisa cache kuenderana pakati peCPU neGPU.

• OCFS2 inode yekutarisa online

• Tsigiro yenzvimbo dzemazita ekgroup

Kuvimbika kunze kwendangariro.

Muurayi weOOM mushanduro dzakapfuura aive nechinangwa chekubvisa basa, aine tarisiro yekuti basa iri rakapedzwa nenguva inogamuchirwa uyezve ndangariro yaizosunungurwa mushure meizvi. Izvo zvakaratidzirwa kuti zviri nyore kuona kuti iko iko kuwanda kwebasa kunotyora iko kufungidzira kuri, uye kuti iye OOM akabatwa anogona kuve nenguva isingaverengeke yenguva yekubuda. Sechiyero cheichi, mune kernel vhezheni 4.6, a ooom_reaper seyakakosha kernel tambo, inoedza kudzoreredza memory, ndiko kuti, kuchinjana chivakwa cheOOM akabatwa nekunze, kana chiyero chekudzivirira cheasina kuzivikanwa ndangariro. Zvese zviri pasi pechirevo chekuti iyi ndangariro haizodiwi.

Kernel multiplexer kubatana.

Iyo multiplexer kernel nzvimbo inopa chinongedzo chinovimba nemeseji pamusoro peTCP, nechinangwa chekumhanyisa masystem ekushandisa. Iyo multiplexer yekubatanidza kernel, kana KCM yezita rayo, inosanganisirwa yeiyi shanduro. Kutenda kune iyo multiplexer yekubatanidza kernel, iyo application inogona kunyatso gamuchira uye kutumira application protocol meseji kuburikidza neTCP. Uyezve, iyo kernel inopa vimbiso yekuti mameseji anotumirwa uye anotambirwa atomically. Kune rimwe divi, iyo kernel inoshandisa meseji meseji yakatarwa neBPF, zvese zvine chinangwa chekuti meseji dzinonangidzirwa pachiteshi cheTCP dzinogona kugamuchirwa mu multiplexer yekubatanidza kernel. Izvo zvinofanirwa kutaura kuti iyo multiplexer yekubatanidza kernel inogona kushandiswa mune hombe nhamba yekushandisa, sezvo mazhinji emabhinari ekushandisa maprotocol anoshanda pasi peichi chiitiko chekuongorora meseji.

Tsigiro ye USB 3.1 SuperSpeedPlus (10 Gbps).

Zve USB 3.1 protocol nyowani yakawedzerwa; iye SuperSpeed ​​​​Plus. Izvi zvinokwanisa kutsigira kumhanya kwe10 Gbps. Inosanganisira USB 3.1 kernel rutsigiro uye iyo USB xHCI inomiririra inomiririra, iyo inosanganisira yakakura kuchengetedza, nekuda kwekubatana kweUSB 3.1 kune USB 3.1 chiteshi chinokwanisa kubata xHCI. Izvo zvakakosha kuti uzive kuti iyo USB zvishandiso zvinoshandiswa kune nyowani SuperSpeedPlus protocol inonzi USB 3.1 Gen2 zvishandiso.

Tsigiro yeIntel memory kuchengetedza makiyi.

Rutsigiro urwu rwunowedzerwa kune chimwe chinhu, kutaura chaizvo nezve Hardware uye nekuchengetedza kwayo ndangariro. Ichi chikamu chichave chinowanikwa mune inotevera Intel CPUs; makiyi ekudzivirira. Aya makiyi anotendera encoding yemushandisi-inodzora masiki mvumo, iri mune zvakanyorwa mutafura peji. Takataura pamusoro pazvo pane kuve neyakagadziriswa dziviriro mask, iyo inoda system yekufona kuti ichinje uye ishande pane peji peji hwaro, ikozvino mushandisi anogona kupa akasiyana akasiyana manhamba senge dziviriro mask. Kana iri nzvimbo yemushandisi, anogona kubata nyaya yekuwana zviri nyore nerejista yemuno yetambo, ayo anogoverwa muzvikamu zviviri zvechifukidzo chimwe nechimwe; kuremadza kuwana uye kuremadza kunyora. Nezvo izvi tinonzwisisa kuvapo kana mukana wekushandura zvine simba mabheji ekudzivirira ezviyero zvakakura zveyeuchidzo, chete nekutungamirwa kweCPU rejista, pasina chikonzero chekuchinja peji rega rega mune chaiyo memory nzvimbo inobatika.

OrangeFS Yakagoverwa Faira Sisitimu.

Iyo LGPL kana kuyera-kunze yakafanana kuchengetedza system. Iyo inoshandiswa zvakanyanya kumatambudziko aripo zvine chekuita nekuchengetedza izvo zvinobatwa muHPC, Big Data, kutenderera kwevhidhiyo kana Bioinformatics. Iine OrangeFS inogona kuwanikwa kuburikidza nemaraibhurari ekubatanidza evashandisi, iyo inosanganisirwa sisitimu yekushandisa, MPI-IO uye inogona kushandiswa nharaunda yeHadoop seimwe nzira yeiyo HDFS faira system.

OrangeFS haiwanzo kudikanwa kuti zvikumbiro zviiswe paVFS, asi mutengi weOrangeFS anoitika kupa mafaera mafaira kugona kuiswa seVFS.

Tsigiro yeshanduro V yeBATMAN protocol.

BATMAN (Zvirinani Nzira Kune Mobile Adhoc Networking) kana ORDINANCE. (Maitiro ari nani ekushambadzira nharembozha netiweki) Ino nguva inosanganisira kutsigira protocol V, sechinotsiva protocol IV. Seimwe yeshanduko dzakanyanya kukosha muBATMA.NV ndiyo metric nyowani, iyo inoratidza kuti protocol haichazotarisika pakurasikirwa kwepaketi. Izvi zvakare zvinopatsanura iyo OGM protocol muzvikamu zviviri; Yekutanga iELP (Echo Nzvimbo Protocol), iri pamusoro pekuongorora mhando yeiyi link uye nekutsvaga vavakidzani. Uye yechipiri, itsva OGM protocol, OGMv2, iyo inosanganisira algorithm iyo inotarisisa nzira dzakanakisa uye inotambanudza metric mukati me network.

802.1AE MAC level encryption.

Tsigiro yeIEEE MACsec 802.1A, chiyero chinopa kunyorera pamusoro peEthernet, chakawedzerwa mukuburitswa uku. Inonyora uye inosimbisa traffic dzese paLAN ine GCM-AES-128. Uye zvakare, chengetedza DHCP uye VLAN traffic, kuitira kuti kubata mumusoro weethernet kudziviswe Iyo yakagadzirirwa kubata iyo MACsec protocol yekuwedzera kiyi, iyo inosanganisa kugoverwa kwemakiyi kune node uye kugoverwa kwematanho.

Izvi zvaive zvimwe zvezvinhu zvakagadziridzwa mushanduro nyowani yeLinux kernel. Iwe unogona kuona kuti pakave nekuvandudza kukuru mukuchengeteka. Izvo zvinoonekwa mune nyowani dzakabatanidzwa zvitsigiro zveCore Zvikamu, ine yakawanda yekusimbisa mukuderedza zvikanganiso. Pakati pezvakawanda zvezvinhu zvaro zvakafukidzwa zveiyi vhezheni 4.6, vagadziri vayo vanosimbisa kuti zvingave zvakanaka kuti masisitimu ane hukama neLinux kernel agadziriswe otomatiki, achitaura nezveLinux uye Android vagoveri. Chinhu chakakosha kwazvo mukati meaya masisitimu, nekuti iyi vhezheni itsva inomira, muzvinhu zvakawanda, seyakachengeteka vhezheni yacho.

Kumwe kuwedzera kwekuchengetedza ndekwekuti Linux ikozvino inoshandisa mapeji akapatsanurwa eiyo Yakawedzera Firmware Interface (EFI) painenge ichiita yayo firmware kodhi. Izvo zvinoenderanawo neBM Power9 processors uye ikozvino Linux ine rutsigiro rweanopfuura gumi nematanhatu masystem masystem pane machipisi (SOC) pamwe nekutsigira kuri nani kwema-13-bit ARM.

Kune rimwe divi, kernel 4.6 inotsigirawo iyo Synaptics RMI4 protocol; Iyi ndiyo yechinyakare protocol kune ese aripo Synaptics touchscreens uye touchpads. Chekupedzisira, rutsigiro rwevamwe ekushandura michina yemunhu inowedzerwawo.

Iyo Linux kernel iri kuratidza kuwedzera uye kuwedzera kusimba maererano nesecurity. Chinhu chinobatsira uye icho chinopa chivimbo muvashandisi vane hukama nesisitimu ino nguva dzese. Kana iwe uchida zvimwe zvakawanda nezve iyo nyowani vhezheni, iwe unogona kuwana iyo yepamutemo Linux kernel peji uye dzidza nezve shanduko.
