Konstantin Komarov, grundl\u00e6gger og leder af Paragon Software, udgav<\/a><\/noindex> i mailinglisten for Linux-kernen et s\u00e6t patches<\/a><\/noindex> med en fuld implementering af filsystemet NTFS<\/a><\/noindex>, der underst\u00f8tter l\u00e6se- og skrivefunktioner. Koden er \u00e5ben under GPL-licensen.<\/p>\n

Implementeringen underst\u00f8tter alle funktioner i den nuv\u00e6rende version af NTFS 3.1, inklusive udvidede filattributter, datakomprimeringsmodus, effektiv h\u00e5ndtering af hulrum i filer og genoprettelse af integriteten efter fejl ved hj\u00e6lp af loggen. Den foresl\u00e5ede driver bruger i \u00f8jeblikket en egen forkortet implementering af NTFS-loggen, men der er planer om senere at tilf\u00f8je support for fuld logf\u00f8ring oven p\u00e5 den eksisterende i kernen for det universelle blokdevice JBD<\/a><\/noindex> (Journaling block device), der danner grundlag for logf\u00f8ring i ext3, ext4 og OCFS2.<\/p>\n

Driveren er baseret p\u00e5 kodebasen fra det eksisterende kommercielle produkt<\/a><\/noindex> Paragon Software og er godt testet. Patchene er udformet i overensstemmelse med kravene til kodeforberedelse til Linux og indeholder ikke afh\u00e6ngigheder til yderligere API'er, hvilket muligg\u00f8r inkludering af den nye driver i hovedkernen. Efter patchene er inkluderet i hovedkernen har Paragon Software planer om at sikre vedligeholdelse, fejlrettelse og udvidelse af funktionaliteten.<\/p>\n

Ikke desto mindre kan inkluderingen i kernen tage tid p\u00e5 grund af behovet for evaluering af den foresl\u00e5ede kode af eksterne udviklere. I kommentarerne til offentligg\u00f8relsen bem\u00e6rkes ogs\u00e5 problemer<\/a><\/noindex> med samling og manglende overholdelse<\/a><\/noindex> af en r\u00e6kke krav<\/a><\/noindex> til patch-udformning. Det foresl\u00e5s for eksempel at opdele den sendte patch i dele, da 27.000 linjer i \u00e9n patch er for mange og skaber vanskeligheder under evaluering og kontrol. I filen MAINTAINERS anbefales det klart at definere politikker for fremtidig kodevedligeholdelse og angive Git-grenen, hvor rettelser skal sendes. Det bem\u00e6rkes ogs\u00e5 n\u00f8dvendigheden af at aftale tilf\u00f8jelsen af den nye NTFS-implementering i lyset af den eksisterende fs\/ntfs-driver, der kun fungerer i skrivebeskyttet tilstand.<\/p>\n

Tidligere m\u00e5tte man bruge FUSE-driveren NTFS-3g for fuld adgang til NTFS-partitioner fra Linux, som k\u00f8rer i brugerrummet og ikke giver den \u00f8nskede ydeevne. Denne driver er ikke blevet opdateret<\/a><\/noindex> siden 2017, ligesom driveren fs\/ntfs, der kun fungerer i l\u00e6setilstand. Begge drivere blev skabt af Tuxera, som, ligesom Paragon Software, leverer<\/a><\/noindex> propriet\u00e6r NTFS-driver, der distribueres kommercielt. <\/p>\n

Lad os minde om, at i oktober sidste \u00e5r, efter publikation<\/a><\/noindex> Microsofts offentligg\u00f8relse af specifikationerne og muligheden for gratis brug af patenter p\u00e5 exFAT i Linux, \u00e5bnede Paragon Software koden til sin driver med implementeringen af FS exFAT. Den f\u00f8rste version af driveren var begr\u00e6nset til at fungere i l\u00e6setilstand, men der var en version under udvikling med skriveunderst\u00f8ttelse. Disse patches blev ikke efterspurgt, og driveren exFAT blev accepteret i den prim\u00e6re kerne, foresl\u00e5et<\/a><\/noindex> Samsung og anvendt i firmware til Android-smartphones fra dette firma. Dette skridt blev taget meget negativt<\/a><\/noindex> i Paragon Software, som reagerede<\/a><\/noindex> kritisk p\u00e5 de \u00e5bne implementeringer af exFAT og NTFS.<\/p>\n
