Oodatud VPN-protokoll<\/h2>\n

\nDavid Miller, kes vastutab Linuxi v\u00f5rgu alams\u00fcsteemi eest, otsustas lubada<\/a><\/noindex> WireGuardi tuumasse. See on VPN-tuunel, mille on v\u00e4lja t\u00f6\u00f6tanud turvafirma Edge Security. Idee arutanud<\/a><\/noindex> oli juba kaks aastat tagasi \u2013 siis toetas seda ise Linus Torvalds \u2013 kuid rakendust l\u00fckati edasi. Projekt oli tugevalt seotud Edge Security kr\u00fcpto funktsioonidega. Kuid kuus kuud tagasi l\u00e4ksid uue protokolli autorid kompromissile ja<\/a><\/noindex> l\u00fclitusid toetatud kr\u00fcpto API-dele.<\/a><\/noindex> , mist\u00f5ttu suudab WireGuard tulevikus asendada OpenVPN. Vastavalt<\/p>\n

Jah arvamus<\/a><\/noindex>testidele , on uue protokolli l\u00e4bilaskev\u00f5ime neli korda suurem kui OpenVPN-l: 1011 Mbit\/s v\u00f5rreldes 258 Mbit\/s. Siiski tasub m\u00e4rkida, et \u00fcleminek juurdeolevale kr\u00fcpto API-le v\u00f5ib tulemusi halvendada.<\/a><\/noindex>Veel \u00fcks WireGuardi omadus on see, et ta<\/p><\/blockquote>\n

Need on plokk-nakkurid, mille aadressiruum on jagatud tsoonideks (n\u00e4iteks NVMe SSD). Failis\u00fcsteem v\u00f5imaldab iga tsooni t\u00f6\u00f6delda kui faili \u2013 see t\u00e4hendab, et kasutatakse spetsiaalseid API-sid asemel<\/a><\/noindex>ioctl haldamatuks. Sarnast l\u00e4henemist kasutatakse andmebaasides RocksDB ja LevelDB. See v\u00f5imaldab v\u00e4hendada koodisiirde kulusid, mis on algselt loodud failidega t\u00f6\u00f6tamiseks.<\/a><\/noindex> Linuxis on juba olemas funktsioon plokkseadmetega suhtlemiseks. 4.13 versiooni tuumas<\/p>\n

Samuti lisatakse<\/a><\/noindex> GeForce 20 seeria (TU10x) graafikakaartide tugi. Vastava draiveri t\u00f6\u00f6tas v\u00e4lja Ben Skeggs Nouveau projektist.

Samuti v\u00f5ivad Linuxi uutel graafikakaartidel esineda j\u00f5udluse probleeme automaatse sageduse juhtimise puudumise t\u00f5ttu.
