K\u00e4imasoleval Linux Plumbers 2022 konverentsil esitles Western Digitali insener eksperimentaalse NVMe liidese SSD-draiveri arendust, mis on kirjutatud Rusti keeles ja t\u00f6\u00f6tab Linuxi tuumatasemel. Kuigi projekt on veel arengu algfaasis, on testimine n\u00e4idanud, et Rusti NVMe draiveri j\u00f5udlus vastab C-keeles kirjutatud NVMe draiverile, mis on juba tuumas olemas.

Ettekandes \u00f6eldakse, et praegune C-keeles NVMe draiver rahuldab arendajaid t\u00e4ielikult, kuid NVMe alams\u00fcsteem on hea platvorm Rusti keeles draiverite arendamise otstarbekuse uurimiseks, kuna see on piisavalt lihtne, laialdaselt kasutatav, n\u00f5uab k\u00f5rgeid j\u00f5udlusstandardeid, omab t\u00f5estatud m\u00f5\u00f5dikut v\u00f5rreldamiseks ja toetab erinevaid liideseid (dev, pci, dma, blk-mq, gendisk, sysfs). <\/p>\n

T\u00e4htis on m\u00e4rkida, et Rusti NVMe draiver pakub juba vajalikku funktsionaalsust, kuid ei ole veel laialdaseks kasutamiseks valmis, kuna vajab t\u00e4iendavaid kohandusi. Tulevikusuundadena mainitakse koodi vabastamist olemasolevatest unsafe-blokidest, seadme eemaldamise operatsioonide ja draiveri \u00fcleslaadimise toe lisamist, sysfs liidese toetust, viivitatud initsialiseerimise loomist, blk-mq draiveri arendamist ja eksperimentide teostamist as\u00fcnkroonse programmeerimismudeli kasutamiseks queue_rq jaoks.

\r\n \"M\u00e4ngi\r\n
<\/div>\r\n <\/div> <\/center> <\/p>\n

Lisaks v\u00f5ib m\u00e4rkida, et NCC Group l\u00e4bi viidud eksperimendid Rusti keeles draiverite v\u00e4lja arendamiseks FreeBSD tuumale. N\u00e4iteks anal\u00fc\u00fcsitakse \u00fcksikasjalikult lihtsat echo-draiverit, mis tagastab andmed, mis on kirjutatud faili \/dev\/rustmodule. Eksperimentide j\u00e4rgmises etapis kaalub NCC Group p\u00f5hiliste tuuma komponentide \u00fcmberehitamist Rusti keeles v\u00f5rgu ja failide operatsioonide turvalisuse t\u00f5stmiseks. <\/p>\n

Kuid vaatamata sellele, et 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 abstraktsiooni kihte tuumas\u00fcsteemide ja struktuuride \u00fcle, sarnased Linuxi projekti Rust for Linux ettevalmistatud lisanditega. Tulevikus planeeritakse sarnaste katsete l\u00e4biviimist Illumose tuumaga ja v\u00e4lja tuua \u00fchised abstraktsioonid Rustis, mida saaks kasutada Rustis kirjutatud draiverites Linuxi, BSD ja Illumose jaoks. <\/p>\n

Microsofti ja Google'i andmetel on umbes 70% nende tarkvaratooteid puudutavatest haavatavustest p\u00f5hjustatud ebaturvalisest m\u00e4lut\u00f6\u00f6st. Eeldatakse, et Rusti keele kasutamine aitab v\u00e4hendada m\u00e4luga seotud haavatavuste tekkimise riski ja v\u00e4listada selliste vigade, nagu m\u00e4lu vabastamise j\u00e4rel sellele p\u00e4\u00e4semine ja puhverpiiridest v\u00e4ljumine, esinemist. <\/p>\n

Rust tagab m\u00e4luga ohutu t\u00f6\u00f6 kompileerimise ajal viidete kontrollimise, objektide omandi j\u00e4lgimise ja objektide eluea (n\u00e4htavuse) arvestamise kaudu ning hindab koodi k\u00e4ivitamise ajal m\u00e4lule juurdep\u00e4\u00e4su \u00f5igust. Rust pakub ka vahendeid t\u00e4isarvude \u00fclet\u00e4itumise kaitsmiseks, n\u00f5uab muutuja v\u00e4\u00e4rtuste kohustuslikku algv\u00e4\u00e4rtustamist enne kasutamist, k\u00e4sitleb vigu paremini standardraamatukogus, rakendab muutujaid ja viiteid vaikimisi muutumatuks (immutable) ning pakub tugevat staatilist t\u00fc\u00fcbi m\u00e4\u00e4ramist loogiliste vigade v\u00e4hendamiseks.
