Praegu toimuval Linux Plumbers 2022 konverentsil esines Western Digital'i insener ettekandega eksperimentaalsest NDME-Express (NVMe) liidese SSD-draiverist, mis on kirjutatud Rust keeles ja t\u00f6\u00f6tab Linuxi kernelis. Kuigi projekt on alles varases arenguetapis, n\u00e4itasid l\u00e4biviidud testid, et NVMe draiveri j\u00f5udlus Rust keeles vastab olemasolevale NVMe draiverile, mis on kirjutatud C keeles.

\"WD<\/center>

Ettekandes \u00f6eldakse, et praegune NVMe draiver C keeles rahuldab arendajaid t\u00e4ielikult, kuid NVMe subs\u00fcsteem on hea koht Rust keeles draiverite arendamise otstarbekuse uurimiseks, kuna see on piisavalt lihtne, laialdaselt kasutatud, n\u00f5uab k\u00f5rget j\u00f5udlust, omab t\u00f5estatud viidete teostust v\u00f5rdlemiseks ja toetab erinevaid liideseid (dev, pci, dma, blk-mq, gendisk, sysfs). <\/p>\n

T\u00f5detakse, et PCI NVMe Rusti draiver pakub juba vajalikke funktsioone, kuid ei ole veel laia kasutuse jaoks valmis, kuna vajab t\u00e4iendavaid parandusi. Tulevikuplaanide seas on koodi vabastamine olemasolevatest unsafe-blokidest, seadme eemaldamise ja draiveri v\u00e4ljav\u00f5tmise toimingute toe lisamine, sysfsi liidese tugi, viivitatud algatuse rakendamine, blk-mq draiveri loomine ja katsetamine as\u00fcnkroonilise programmeerimise mudeli kasutamisega queue_rq jaoks.

Lisaks v\u00f5ib m\u00e4rkida, et NCC Group viib l\u00e4bi katseid Rusti keeles draiverite arendamiseks FreeBSD kerneli jaoks. N\u00e4iteks anal\u00fc\u00fcsitakse p\u00f5hjalikult lihtsat echo-draiverit, mis tagastab andmed, mis on kirjutatud faili \/dev\/rustmodule. Katsede j\u00e4rgmises etapis kaalub NCC Group baas komponendi \u00fcmbertegemist Rusti keeles, et suurendada v\u00f5rgu- ja failitegevuste turvalisust. <\/p>\n

Sellegipoolest, kuigi on n\u00e4idatud v\u00f5imalust luua lihtsaid mooduleid Rusti keeles, n\u00f5uab Rusti tihedam integreerimine FreeBSD tuumaga t\u00e4iendavat t\u00f6\u00f6d. N\u00e4iteks mainitakse vajadust luua abstraktsioonikihtide komplekt s\u00fcstemaatikate ja tuuma struktuuride \u00fcle, mis sarnaneb Rust for Linux projekti ettevalmistatud kihtidega. Edasi kavatsetakse l\u00e4bi viia sarnaseid katsetusi Illumosi tuumaga ning eraldada \u00fcldised Rusti abstraktsioonid, mida saaks kasutada Rustis kirjutatud draiverite jaoks Linuxis, BSD-s ja Illumosel. <\/p>\n

Microsofti ja Google'i ettev\u00f5tete andmetel p\u00f5hjustab umbes 70% nende tarkvaratoodete haavatavustest ebaturvaline m\u00e4lu kasutamine. Eeldatakse, et Rusti keele kasutamine v\u00e4hendab m\u00e4lu ebaturvalisest t\u00f6\u00f6tlemisest tulenevate haavatavuste riski ning k\u00f5rvaldab sellised vead nagu m\u00e4lupiirkonna kasutamine p\u00e4rast selle vabastamist ja puhvri piirest v\u00e4ljumine. <\/p>\n

Rust tagab m\u00e4lut\u00f6\u00f6 turvalisust kompileerimise ajal viidatud linkide kontrollimise, objektide omaniku j\u00e4lgimise ja objektide eluea arvestamise (n\u00e4htavuse) kaudu, samuti p\u00e4rast koodi k\u00e4itamise ajal m\u00e4lu juurdep\u00e4\u00e4su \u00f5igsuse hindamise kaudu. Rust pakub ka vahendeid t\u00e4isarvude \u00fclevoolude eest kaitsmiseks, n\u00f5uab muutuja v\u00e4\u00e4rtuste kohustuslikku initsialiseerimist enne kasutamist, haldab vigu paremini standardraamatukogus, rakendab muutumatuse (immutable) kontseptsiooni linkide ja muutujate puhul vaikimisi ning pakub tugevat staatilist t\u00fc\u00fcpimist loogiliste vigade minimeerimiseks.
