Kerla projekti raames t\u00f6\u00f6tatakse v\u00e4lja operatsioonis\u00fcsteemi kernelit, mis on kirjutatud Rust-i keeles. Uus kernel on algselt suunatud ABI tasemel Linuxi kerneliga \u00fchilduvuse tagamisele, mis v\u00f5imaldab Kerla-p\u00f5hises keskkonnas k\u00e4itada muutmata t\u00e4itmisfaile, mis on loodud Linuxile. Kood on litsentseeritud Apache 2.0 ja MIT alla. Projekti arendab Jaapani arendaja Seiya Nuta, kes on tuntud kernelip\u00f5hise operatsioonis\u00fcsteemi Resea loomise poolest, mis on kirjutatud C keeles. <\/p>\n

Kerla arenguetapis suudab see t\u00f6\u00f6tada ainult x86_64 arhitektuuri s\u00fcsteemides ja rakendab p\u00f5hiv\u00e4\u00e4rtpabereid, nagu write, stat, mmap, pipe ja poll, toetades signaale, nimetamata kanaleid ja konteksti vahetusi. Protsesside haldamiseks pakutakse selliseid k\u00f5nesid nagu fork, wait4 ja execve. Toetatakse tty-d ja pseudoterminaale (pty). Hetkel on faidis\u00fcsteemides toetatud initramfs (kasutatakse juur-FS-i mountimiseks), tmpfs ja devfs. Pakutakse \u00fchenduskihti, mis toetab TCP ja UDP sokke, kasutades smoltcp teeki. <\/p>\n

Arendaja on ette valmistanud laadimiskeskkonna, mida k\u00e4ivitatakse QEMU-s v\u00f5i virtuaalmasinas<\/a> Firecracker virtio-net draiveriga, millega on juba v\u00f5imalik SSH kaudu \u00fchendust v\u00f5tta. S\u00fcsteemiraamatukoguna kasutatakse musl'i ja kasutajate utiliitidena \u2014 BusyBox.

\"Kerla<\/center> <\/p>\n

Dockeri p\u00f5hjal on loodud ehituss\u00fcsteem, mis v\u00f5imaldab luua oma laadimis-initramfs Kerla tuumaga. Eraldi arendatakse fish-i sarnast tarkvarakeelt nsh ja GUI-kihi Kazari, mis p\u00f5hineb Waylandi protokollil.

Rust'i kasutamine projektis v\u00e4hendab koodivigu, rakendades turvalise programmeerimise tehnikaid ning parandades probleemide tuvastamise t\u00f5husust m\u00e4lu haldamisel. Rust tagab m\u00e4lu turvalise kasutamise kompileerimise ajal, kontrollides viiteid, j\u00e4lgides objektide omandit ja arvestades objektide eluts\u00fcklit (n\u00e4htavust), samuti hinnates m\u00e4lu juurdep\u00e4\u00e4su \u00f5igsust koodi t\u00e4itmise ajal. Lisaks pakub Rust vahendeid t\u00e4isarvude \u00fclevoolu ennetamiseks, n\u00f5uab muutuja v\u00e4\u00e4rtuste kohustuslikku algv\u00e4\u00e4rtustamist enne nende kasutamist, rakendab muutujaid ja viiteid p\u00f5hjalikult muutumatuks (immutable) ning pakub tugevat staatilist t\u00fcpiseerimist loogikavigade minimeerimiseks, muudab sisendite k\u00e4sitlemise lihtsamaks, pakkudes mustrite j\u00e4rgi sobitamise t\u00f6\u00f6riistu. <\/p>\n

Madala taseme komponentide, n\u00e4iteks OS-i tuuma, arendamiseks pakub Rust toimetajaid, andmestruktuuride pakkimist, assembleri inline-sisendeid ja failide integreerimist assembleris. Standardraamatukogist s\u00f5ltumatute tegevuste jaoks on olemas eraldi crate-pakid stringide, vektorite ja bitiflagide t\u00f6\u00f6tlemiseks. Eeliste hulka kuuluvad ka sisseehitatud t\u00f6\u00f6riistad koodi kvaliteedi hindamiseks (linter, rust-analyzer) ja unit-testide loomine, mida saab k\u00e4itada mitte ainult reaalsetel seadmetel, vaid ka QEMU-s.
