Kerla projekti raames arendatakse operatsioonis\u00fcsteemi tuuma, mis on kirjutatud Rust keeles. Uus tuum on algselt suunatud ABI tasemel \u00fchilduvuse tagamisele Linuxi tuumaga, mis v\u00f5imaldab Kerla alusel keskkonnas k\u00e4itada muutmata t\u00e4itmisfaile, mis on loodud Linuxile. Kood on levitatud litsentside alla Apache 2.0 ja MIT. Projekti arendab Jaapani arendaja Seiya Nuta, kes on tuntud mikrokernele p\u00f5hineva operatsioonis\u00fcsteemi Resea loomise poolest, mis on kirjutatud C keeles. <\/p>\n

Praegusel Kerla arendusetapis saab s\u00fcsteem t\u00f6\u00f6tada ainult x86_64 arhitektuuriga seadmetes ning toetab p\u00f5hilisi s\u00fcsteemikutsungeid, nagu write, stat, mmap, pipe ja poll, toetab signaale, nimetatud kanaleid ja konteksti vahetust. Protsesside haldamiseks on olemas kutsungid nagu fork, wait4 ja execve. Toetatakse tty ja psevdoterminale (pty). Failis\u00fcsteemidest toetatakse praegu initramfs (kasutatakse juurte failis\u00fcsteemi mountimiseks), tmpfs ja devfs. Saadaval on v\u00f5rgu stack, mis toetab TCP ja UDP sokkleid, mis on rakendatud smoltcp teegi baasil. <\/p>\n

Arendaja on valmistanud laadimiskeskkonna, mida saab k\u00e4itada QEMU-s v\u00f5i virtuaalses masinas<\/a> Firecracker virtio-neti draiveriga, millele on juba v\u00f5imalik SSH kaudu \u00fchenduda. S\u00fcsteemiks on kasutusel musl ja kasutajaliidese t\u00f6\u00f6riistadena — BusyBox.

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

Docker'i p\u00f5hjal on loodud ehituss\u00fcsteem, mis v\u00f5imaldab luua oma laadimis initramfs Kerla tuumaga. T\u00e4iendavalt arendatakse fishile sarnast nsh k\u00e4surealiidest ja GUI steki Kazari, mis p\u00f5hineb Waylandi protokollil.

Rusti keele kasutamine projektis v\u00e4hendab koodivigu, kasutades turvalise programmeerimise tehnikaid ja suurendades probleemide avastamise efektiivsust m\u00e4luga t\u00f6\u00f6tamisel. Rust tagab turvalise m\u00e4lu kasutamise kompileerimise ajal viidatud kontrollimise, objektide omamise j\u00e4lgimise ja objektide eluiga (ulatus) arvesse v\u00f5tmise kaudu ning hindab m\u00e4lu juurdep\u00e4\u00e4su \u00f5igsust koodi t\u00e4itmise ajal. Lisaks pakub Rust vahendeid tervete arvude \u00fclevoolude kaitsmiseks, n\u00f5uab muutuja v\u00e4\u00e4rtuste kohustuslikku initsialiseerimist enne kasutamist, rakendab vaikesena muutmatute (immutable) viidete ja muutujate kontseptsiooni ning pakub tugevat staatilist t\u00fcpiseerimist, et minimeerida loogilisi vigu ning lihtsustada sisendv\u00e4\u00e4rtuste t\u00f6\u00f6tlemist mustrite \u00fchtesamadamise vahendite kaudu. <\/p>\n

Madala taseme komponentide, nagu operatsioonis\u00fcsteemi tuum, arendamiseks pakub Rust to support raw-viidiseid, struktuuride paketitamist, assembleri inline-sisendeid ja failide sissetoomist assembleris. Standardraamatukogist s\u00f5ltumatuteks t\u00f6\u00f6deks on eraldatud crate-paketid stringide, vektorite ja bitilippude operatsioonide t\u00e4itmiseks. Samuti m\u00e4rgitakse tugevateks k\u00fclgedeks sisseehitatud t\u00f6\u00f6riistad koodi kvaliteedi hindamiseks (linter, rust-analyzer) ja unit-testide loomine, mida saab k\u00e4ivitada mitte ainult reaalses riistvaras, vaid ka QEMU-s.
