J\u00e4tkates Fedora<\/a><\/noindex> ja Debian<\/a><\/noindex> Ubuntu arendajad kaaluvad v\u00f5imalust<\/a><\/noindex> siirdumist vaikimisi pakettifiltri kasutamisele nftables<\/a><\/noindex>.
\nTagasip\u00f6\u00f6rdumise \u00fchilduvuse s\u00e4ilitamiseks soovitatakse kasutada paketti iptables-nft<\/a><\/noindex>, mis pakub utiliite sama k\u00e4suree s\u00fcntaksiga nagu iptables, kuid t\u00f5lgib saadud reeglid nf_tables byte-koodiks. Muudatus kavas lisada Ubuntu 20.10 s\u00fcgisversioonis.<\/p>\n

See on teine katse Ubuntu siirdumiseks nftables'ile. Esimene katse tehti eelmisel aastal, kuid see l\u00fckati tagasi \u00fchilduvuse probleemide t\u00f5ttu LXD<\/a><\/noindex>. N\u00fc\u00fcd on LXD-l juba on olemas<\/a><\/noindex> sisseehitatud tugi nftables'ile ja see suudab t\u00f6\u00f6tada uue pakettide filtreerimise taustaga. Kasutajatele, kellele ei piisa \u00fchilduvuskihist, on j\u00e4tkuvalt<\/a><\/noindex> on olemas v\u00f5imalus installida vanade taustadega klassikalisi utiliite iptables, ip6tables, arptables ja ebtables.<\/p>\n

Tuletame meelde, et pakettfiltris nftables<\/a><\/noindex> on \u00fchtlustatud pakettide filtreerimise liidesed IPv4, IPv6, ARP ja v\u00f5rgu sillade jaoks. nftables paketti kuuluvad kasutaja ruumis t\u00f6\u00f6tavad pakettfiltri komponendid, samas kui tuuma tasemel haldab t\u00f6\u00f6d nf_tables alams\u00fcsteem, mis sisalduvad Linuxi k\u00e4rjes alates versioonist 3.13. Tuuma tasemel pakutakse vaid \u00fcldist liidest, mis ei s\u00f5ltu konkreetsest protokollist ja tagab p\u00f5hilised funktsioonid andmete ekstraktsiooniks pakettidest, andmete t\u00f6\u00f6tlemiseks ja voo juhtimiseks. <\/p>\n

Filtreerimise reeglid ja protokollispetsiifilised t\u00f6\u00f6tlejad kompileeritakse kasutaja ruumis byte-koodiks, seej\u00e4rel laaditakse see byte-kood tuumasse Netlinki liidese kaudu ja seda t\u00e4idetakse tuumas spetsiaalses virtuaalses masinas, mis sarnaneb BPF-iga (Berkeley Packet Filters). Selline l\u00e4henemine v\u00f5imaldab oluliselt v\u00e4hendada filtseerimise koodi suurust, mis t\u00f6\u00f6tab tuuma tasemel, ja viia k\u00f5ik reeglite t\u00f5lgendamise ja protokollide t\u00f6\u00f6tlemise loogika kasutaja ruumi.<\/p>\n
