Cisco on tutvustanud uut failis\u00fcsteemi PuzzleFS, mis on rakendatud Linuxi tuumamoodulina ja kirjutatud Rust keeles. Failis\u00fcsteem on m\u00f5eldud isoleeritud konteinerite majutamiseks ning j\u00e4tkab Atomfs failis\u00fcsteemi ideede arendamist. Rakendus on hetkel protot\u00fc\u00fcbi etapis, toetab kokkupanekut Linuxi tuuma rust-next haruga ning on avatud Apache 2.0 ja MIT litsentside all. <\/p>\n

Projekt on suunatud OCI (Open Container Initiative) konteineripiltide kasutamisel tekkivate piirangute \u00fcletamisele. PuzzleFS lahendab sellised probleemid nagu korduvate andmete t\u00f5hus salvestamine, otsemontaa\u017e, piltide korduv koostamine ja m\u00e4lu turvaline kasutamine. <\/p>\n

Korduvate andmete dedupelikatsioonis konteiners kasutatakse FastCDC (Fast Content-Defined Chunking) algoritmi, mis t\u00f6\u00f6tab, jagades andmed suvalise suurusega fragmentideks ja haldades sealjuures t\u00f6\u00f6deldud fragmentide hash-e. Korduvad fragmendid salvestatakse \u00fcks kord ja indekseeritakse \u00fchiselt k\u00f5igi failis\u00fcsteemi kihtide jaoks, s.t. dedupelikatsioon v\u00f5ib katab katta erinevaid monteerimispunkte (uus failis\u00fcsteemi kiht v\u00f5ib k\u00e4ivituda olemasoleva alusel ja kasutada selle andmefragmente dedupelikatsiooniks). <\/p>\n

Konteinerite piltide korduv koostamine saavutatakse konteineripiltide formaadi kanonilise esinduse m\u00e4\u00e4ratlemise kaudu. Otsemontaa\u017e (direct-mount) v\u00f5imaldab OCI formaadis konteineripilti montaa\u017eida globaalsetes \u00fchiselt kasutatavas hoidlas ilma eelneva dekompressioonita ning kasutades sisu hash-i konteineri manifestist identifikaatorina. Andmete terviklikkuse kontrollimiseks \u00fchissalvestuse korral v\u00f5ib kasutada fs-verity mehhanismi, mis kontrollib failide suhtes antud binaarse indeksi hash-e vastavust tegelikule sisule. <\/p>\n

Rust keele valik on seotud tulemuskoodi k\u00f5rge j\u00f5udluse ja m\u00e4lu turvalise kasutamise v\u00f5imalustega, mis aitab v\u00e4hendada haavatavuste tekkimise riski, mis on tingitud n\u00e4iteks m\u00e4luhaldusest p\u00e4rast m\u00e4lu vabastamist ja puutumatuse piire \u00fcletamisest. Rusti kasutamine tuumamooduli jaoks on samuti v\u00f5imaldanud jagada koodi tuumas ja kasutajaruumi komponentides, et luua \u00fchtne turvaline rakendus. <\/p>\n

Projekti teiste eesm\u00e4rkide hulka kuuluvad: v\u00e4ga kiire piltide koostamine ja montaa\u017e, valikuline vahepealne etapp piltide kanoniseerimiseks, puhtuse tagamise jaoks ei ole vajalik t\u00e4ies mahus puude kasutamine failis\u00fcsteemi puu struktuuri, muutuste rakendamine casync stiilis ja lihtne teostuse arhitektuur.
