Linux kernel 5.6 v\u00e4ljalaskmine on planeeritud m\u00e4rtsi l\u00f5puks. T\u00e4na arutame, millised muutused on tulemas \u2013 uus failis\u00fcsteem, WireGuard protokoll ja draiverite uuendused.<\/p>\n

Oodatud VPN-protokoll<\/h2>\n

\nDavid Miller, kes vastutab Linuxi v\u00f5rgus\u00fcsteemi eest, otsustas l\u00fclitada sisse<\/a><\/noindex> kaasa v\u00f5tta WireGuardi tuumasse. See on VPN-tunnel, mille arendas v\u00e4lja k\u00fcberjulgeoleku ettev\u00f5te Edge Security. Idee arutasime<\/a><\/noindex> oli juba kaks aastat tagasi \u2013 siis, kui toetas<\/a><\/noindex> isegi Linus Torvalds \u2013 kuid rakendamine viibis. Projekt oli tugevalt seotud Edge Security kr\u00fcpto-funktsioonidega. Kuus kuud tagasi leidsid uue protokolli autorid kompromissi ja \u00fcleminek<\/a><\/noindex> toetatavatele Crypto API-dele.<\/p>\n

On arvamus<\/a><\/noindex>, mis tulevikus v\u00f5imaldab WireGuardil asendada OpenVPN-i. Vastavalt testide<\/a><\/noindex>, on uue protokolli l\u00e4bilaskev\u00f5ime neli korda suurem kui OpenVPN-il: 1011 Mbit\/s v\u00f5rreldes 258 Mbit\/s. Siiski tasub m\u00e4rkida, et \u00fcleminek ametlikule Crypto API-le v\u00f5ib tulemusi halvendada.<\/p><\/blockquote>\n

\nVeel \u00fcks WireGuardi omadus on see, et ta ei katkesta \u00fchendust<\/a><\/noindex>, isegi kui kasutaja on saanud uue IP-aadressi, ja lahendab marsruutimise probleemid automaatselt. Selleks seotakse igale v\u00f5rguliidesele privaatv\u00f5ti. See genereeritakse kasutades Diffie-Hellmani protokolli<\/a><\/noindex>. Kr\u00fcpteerimine ise on ehitatud<\/a><\/noindex> kasutab ChaCha20 ja algoritmi Poly1305<\/a><\/noindex>. Need peetakse paremaks alternatiiviks AES-256-CTR-le ja HMAC<\/a><\/noindex>.<\/p>\n

Uus failis\u00fcsteem<\/h2>\n

\nSelle s\u00fcsteemi oli<\/a><\/noindex> Zonefs, tutvustasid Western Digitali insenerid. See on m\u00f5eldud zoneeritud salvestusseadmetega t\u00f6\u00f6tamiseks (zoned storage<\/a><\/noindex>). Need on plokkn\u00f5udjad, mille adressiruumi on jagatud tsoonideks (n\u00e4iteks NVMe SSD). Failis\u00fcsteem v\u00f5imaldab iga tsooni t\u00f6\u00f6delda nagu faili \u2013 see t\u00e4hendab spetsiaalsete API-de kasutamist selle asemel, et ioctl<\/a><\/noindex> salvestus- ja andmeteenuste jaoks. Sarnast l\u00e4henemist kasutatakse andmebaasides RocksDB ja LevelDB. See annab v\u00f5imaluse v\u00e4hendada koodide \u00fclekandmise kulusid, mis on algselt m\u00f5eldud failidega t\u00f6\u00f6tamiseks.<\/p>\n

Linuxis on juba funktsioon plokiseadmetega suhtlemiseks. 4.13 versiooni tuumas ilmus<\/a><\/noindex> moodul dm-zoned. See esitab zoneeritud salvestuslahenduse kui tavalise plokkseadmestiku, samas kui Zonefs on alternatiiv.<\/p>\n

Lisaks uue failis\u00fcsteemi rakendamisele on Linux kernelisse tehtud muudatusi ka olemasolevates. On olnud lisatud<\/a><\/noindex> survemehhanismid LZO<\/a><\/noindex>\/LZ4<\/a><\/noindex> F2FS jaoks \u2013 nende tugi j\u00e4\u00e4b hetkel veel katsetatavaks. See tuleb manuaalselt aktiveerida, kui jaotust on montaa\u017eis (valik compress_algorithm<\/i>). Samuti on uuendatud will receive<\/a><\/noindex> EXT4 \u2013 see on seotud otse\u00fclekande toimingutega. Uuenduste paketti esitles IBM-i insener Ritesh Harjan. Tema s\u00f5nul<\/a><\/noindex>, m\u00f5nel juhul v\u00f5ib plaastrile t\u00f5sta failis\u00fcsteemi j\u00f5udlust 140% v\u00f5rra.<\/p>\n

Draiveri uuendused<\/h2>\n

\nTuumas ilmub uus draiver cpuidle_cooling<\/i>. Tema \u00fclesanne<\/a><\/noindex> , et jahutada CPU \/ SoC, sisestades t\u00fchik\u00e4igud t\u00f6\u00f6 k\u00e4igus. Mingil m\u00e4\u00e4ral sarnaneb see Intel protsessorite PowerClamp draiveriga, kuid ei ole seotud kindla arhitektuuriga. Selle s\u00fcsteemi v\u00e4lja andsid<\/a><\/noindex> on v\u00e4lja t\u00f6\u00f6tanud Linaro spetsialistid, kes tegelevad avatud l\u00e4htekoodiga tarkvara optimeerimisega ARM-i platvormidel.<\/p>\n

Samuti lisatakse<\/a><\/noindex> GeForce 20 seeria (TU10x) graafikakaartide tugi. Vastava draiveri on v\u00e4lja t\u00f6\u00f6tanud Ben Skeggs Nouveau projektist. Kahjuks j\u00e4\u00e4b GeForce 16 (TU11x) hetkel \"aga\". Nvidia ei ole esitanud vajalikke mikrokoodide pilte kaardi initsialiseerimiseks. Samuti v\u00f5ivad uute graafikakaartide j\u00f5udlusega Linuxis esineda probleeme, kuna puudub automaatne kellalaud \u2013 sageduse juhtimine. Varasemalt on t\u00f5estatud, et Nouveau draiverid v\u00f5ivad toimida<\/a><\/noindex> 20-30% aeglasemalt originaalsetest.<\/p>\n

Veel \u00fcks uus tuum toetab<\/a><\/noindex> USB4. Vastavad muudatused pakuvad<\/a><\/noindex> on teinud Intel'i insenerid. Nad on modifitseerinud olemasolevat koodibaasi, mis on seotud Thunderboltiga \u2013 see on umbes kaks tuhat rida.<\/p>\n

Muidugi ei ole need k\u00f5ik uuendused, mis tuuma tulevad \u2013 n\u00e4iteks v\u00f5ib oodata<\/a><\/noindex> t\u00e4iendavat perifeeriat ja v\u00f5rguseadmete tuge. Samuti saab kernel 5.6 esimeseks 32-bitiseks tuumaks, kus lahendatakse<\/a><\/noindex> 2038. aasta probleem.<\/a><\/noindex>. Jaanuari l\u00f5pus on insenerid teinud<\/a><\/noindex> l\u00f5plikud muudatused nfsd, xfs, alsa ja v4l2. Nad loodavad, et kaheksa aastaga, mis on veel j\u00e4\u00e4nud, suudavad kasutajad ja levitamise arendajad \u00fcle minna kernel 5.6-le (v\u00f5i sellele j\u00e4rgnevatele versioonidele).<\/p>\n
