Podjetje Cisco je predstavilo nov datote\u010dni sistem PuzzleFS, implementiran kot modul za jedro Linux, napisan v jeziku Rust. Sistem je zasnovan za uporabo pri name\u0161\u010danju izoliranih kontejnerjev in nadaljuje razvoj idej, predlaganih v datote\u010dnem sistemu Atomfs. Implementacija je trenutno v fazi prototipa, podpira gradnjo z veje jedra Linux rust-next in je odprta pod licencami Apache 2.0 in MIT. <\/p>\n

Projekt si prizadeva obiti omejitve, ki nastanejo pri uporabi kontejnerskih slik v formatu OCI (Open Container Initiative). PuzzleFS re\u0161uje te\u017eave, kot so u\u010dinkovito shranjevanje podvojenih podatkov, mo\u017enost neposrednega monta\u017ee, ponovna gradnja slik in varno delo z pomnilnikom. <\/p>\n

Za deduplikacijo ponavljajo\u010dih se podatkov v razli\u010dnih kontejnerjih se uporablja algoritem FastCDC (Fast Content-Defined Chunking), ki deluje z razdelitvijo podatkov na ko\u0161\u010dke poljubne velikosti in s prowadzeniem indeksa s Hashi obdelanih ko\u0161\u010dkov. Ponavljajo\u010di se ko\u0161\u010dki se shranijo samo enkrat in se skupno indeksirajo za vse plasti sistema, torej lahko deduplikacija zajema razli\u010dne to\u010dke monta\u017ee (nova plast sistema se lahko za\u017eene na osnovi obstoje\u010de in uporabi ko\u0161\u010dke podatkov, ki so \u017ee prisotni pri deduplikaciji). <\/p>\n

Ponovna gradnja kontejnerskih slik dose\u017eemo z definiranjem kanoni\u010dne reprezentacije formata kontejnerskih slik. Neposredna monta\u017ea (direct-mount) omogo\u010da montiranje slike kontejnerja v formatu OCI iz globalnega skupno rabljenega skladi\u0161\u010da brez predhodne razpakiranja, pri \u010demer se kot identifikator uporablja Hash vsebine iz manifestacijo kontejnerja. Za preverjanje celovitosti podatkov v pogojih skupnega skladi\u0161\u010da se lahko uporablja mehanizem fs-verity, ki ob dostopu do datotek preverja skladnost navedenih v binarnem indeksu Hash z dejansko vsebino. <\/p>\n

Jezik Rust je izabran zbog kombinacije visoke performanse rezultantnog koda sa mogu\u0107nostima za sigurnu manipulaciju memorijom, \u0161to smanjuje rizik od pojave ranjivosti uzrokovanih problemima kao \u0161to su pristup oslobo\u0111enoj memoriji i izlazak van granica bafera. Kori\u0161\u0107enje Rusta za kernel modul tako\u0111e je omogu\u0107ilo deljenje koda izme\u0111u kernela i komponenti koje rade u korisni\u010dkom prostoru, \u010dime se stvara jedinstvena sigurna implementacija. <\/p>\n

Me\u0111u drugim ciljevima projekta: vrlo brzo prevo\u0111enje i montiranje slika, mogu\u0107nost kori\u0161\u0107enja opcione me\u0111ustepenice za konverziju (kanonizaciju) slika, neobveznost potpunih prolaza kroz stablo F\u0421 u mtree stilu kod vi\u0161eslojne strukture, primena promena u stilu casync i jednostavna za implementaciju arhitektura.
