Detta \u00e4r det andra f\u00f6rs\u00f6ket att \u00f6verg\u00e5 Ubuntu till nftables. Det f\u00f6rsta f\u00f6rs\u00f6ket gjordes f\u00f6rra \u00e5ret men avvisades p\u00e5 grund av inkompatibilitet med verktygen. LXD<\/a><\/noindex>. Nu i LXD finns det har<\/a><\/noindex> inbyggt st\u00f6d f\u00f6r nftables och det kan fungera med den nya backend f\u00f6r paketfiltering.

Kom ih\u00e5g att i paketfiltret nftables<\/a><\/noindex> \u00e4r gr\u00e4nssnitt f\u00f6r paketfiltrering enhetliga f\u00f6r IPv4, IPv6, ARP och n\u00e4tverksbroar. Paketet nftables inneh\u00e5ller komponenter av paketfilter som arbetar i anv\u00e4ndarrummet, medan k\u00e4rnans nf_tables underh\u00e5lls av k\u00e4rnan i Linux sedan version 3.13. P\u00e5 k\u00e4rnniv\u00e5 erbjuds endast ett gemensamt gr\u00e4nssnitt som inte beror p\u00e5 specifika protokoll och erbjuder grundl\u00e4ggande funktioner f\u00f6r datainsamling fr\u00e5n paket, datamanipulation och fl\u00f6deshantering. <\/p>\n

Sj\u00e4lva filtreringsreglerna och protokollspecifika hanterare kompileras till bytekod i anv\u00e4ndarrummet, vars bytekod sedan laddas in i k\u00e4rnan via Netlink-gr\u00e4nssnittet och k\u00f6rs i k\u00e4rnan i en speciell virtuell maskin som liknar BPF (Berkeley Packet Filters). Denna metod s\u00e4kerst\u00e4ller att storleken p\u00e5 den filteringkod som k\u00f6rs p\u00e5 k\u00e4rnniv\u00e5 minskas avsev\u00e4rt och att alla funktioner f\u00f6r reglerparsing och protokollhantering flyttas till anv\u00e4ndarrummet.<\/p>\n
