Cisco on esitanud uut failis\u00fcsteemi PuzzleFS, mis on rakendatud Linuxi tuuma moodulina ja kirjutatud Rusti keeles. See failis\u00fcsteem on m\u00f5eldud isoleeritud konteinerite majutamiseks ning j\u00e4tkab Atomfs-i pakutud ideede arengut. Teostus on praegu protot\u00fc\u00fcpimise faasis, toetab kokkupanekut Linuxi tuuma rust-next haruga ja on avatud Apache 2.0 ja MIT litsentside all. <\/p>\n

Projekt on suunatud konteineripiltide kasutamisel ilmnevate piirangute \u00fcletamisele OCI (Open Container Initiative) formaadis. PuzzleFS lahendab sellised probleemid nagu efektiivne duplikaatandmete salvestamine, otsene mountimine, piltide korduv kogumine ja ohutu m\u00e4lukasutus. <\/p>\n

Erinevates konteinerites korduvate andmete deduplikatsiooniks kasutatakse algoritmi FastCDC (Fast Content-Defined Chunking), mis jagab andmed juhusliku suurusega fragmentideks ja hoiab indeksit t\u00f6\u00f6deldud fragmentide hash-koodidelt. Korduvad fragmendid salvestatakse \u00fcks kord ja indekseeritakse \u00fchiselt k\u00f5igi failis\u00fcsteemi kihtide jaoks, st deduplikatsioon v\u00f5ib h\u00f5lmata erinevaid mountimispunkte (uus failis\u00fcsteemi kiht v\u00f5ib olla k\u00e4ivitatud olemasolevast ja kasutada selles olevaid andmefragmente deduplikatsiooniks). <\/p>\n

Konteineripiltide korduv kogumine saavutatakse, m\u00e4\u00e4rates kindlaks konteineripiltide formaadi kanonilise esitusviisi. Otsene mountimine (direct-mount) v\u00f5imaldab mountida OCI formaadis konteineripilti globaalsest jagatud salvestust kriimustamata, kasutades sisu hash-koodi, mis on saadud konteineri manifestist. Andmete terviklikkuse kontrollimiseks jagatud salvestuse tingimustes v\u00f5ib rakendada mehhanismi fs-verity, mis kontrollib failide juurde p\u00e4\u00e4semisel binaarindeksi hash-koodide vastavust tegelikule sisule. <\/p>\n

Rusti keel valiti, kuna see \u00fchendab tulemuskoodide k\u00f5rge j\u00f5udluse m\u00e4lu ohutuse v\u00f5imalustega, mis v\u00e4hendab haavatavuste tekkimise riski, n\u00e4iteks p\u00e4rast vabastamist m\u00e4lupiirkonda juurde p\u00e4\u00e4semine ja m\u00e4lupiiri \u00fcletamine. Rusti kasutamine tuumamooduli jaoks v\u00f5imaldas ka koodi jagada tuumas ja kasutajaruumi komponentides, luues \u00fche kaitstud teostuse. <\/p>\n

Projekti teiste eesm\u00e4rkide seas on v\u00e4ga kiire piltide koostamine ja monteerimine, v\u00f5imalus kasutada vabatahtlikku vahefaasi piltide kanoniseerimiseks, t\u00e4ielike l\u00e4bide puudumine fs-puu stiilis mtree, kui kasutatakse kihilist struktuuri, muudatuste kohaldamine casync stiilis ja lihtne rakendatav arhitektuur.
