Grupa deweloper\u00f3w z Chin rozwija j\u0105dro Asterinas, napisane w j\u0119zyku Rust, przeznaczone do u\u017cycia w systemach operacyjnych og\u00f3lnego przeznaczenia. Aby upro\u015bci\u0107 integracj\u0119 z ju\u017c stworzonymi komponentami systemowymi, j\u0105dro oferuje ABI (Application Binary Interface) zgodne z j\u0105drem Linux, kt\u00f3re mo\u017ce by\u0107 u\u017cywane zamiast niego. Kod projektu jest rozpowszechniany na mocy licencji MPL (Mozilla Public License). <\/p>\n

Projekt rozwija si\u0119 od jesieni 2022 roku i ma na celu osi\u0105gni\u0119cie poziomu, kt\u00f3ry b\u0119dzie odpowiedni do szerokiego u\u017cytku jeszcze w tym roku w maszynach wirtualnych<\/a> architekturze x86-64. Od przysz\u0142ego roku planuje si\u0119 skoncentrowa\u0107 na implementacji wsparcia dla sprz\u0119tu i innych architektur CPU. W\u015br\u00f3d priorytetowych obszar\u00f3w zastosowa\u0144 wymieniane s\u0105 systemy, kt\u00f3re korzystaj\u0105 z Linux ABI, ale wymagaj\u0105 wy\u017cszego poziomu bezpiecze\u0144stwa. Na przyk\u0142ad, Asterinas ma by\u0107 wykorzystywane do tworzenia \u015brodowiska systemowego dla zabezpieczonych maszyn wirtualnych<\/a>, do izolacji kt\u00f3rych wykorzystuje si\u0119 takie technologie, jak ARM CCA, AMD SEV i Intel TDX, oraz po stronie systemu gospodarza, zapewniaj\u0105cego uruchamianie kontener\u00f3w. <\/p>\n

Aby zmniejszy\u0107 prawdopodobie\u0144stwo wyst\u0105pienia b\u0142\u0119d\u00f3w podczas pracy z pami\u0119ci\u0105, kt\u00f3re s\u0105 g\u0142\u00f3wnym \u017ar\u00f3d\u0142em najniebezpieczniejszych podatno\u015bci, w programowaniu Asterinas zastosowano j\u0119zyk Rust oraz taktyk\u0119 ograniczonego u\u017cywania blok\u00f3w unsafe. J\u0105dro zbudowane jest z wykorzystaniem architektury framekernel, w kt\u00f3rej deweloperzy starali si\u0119 po\u0142\u0105czy\u0107 mo\u017cliwo\u015bci izolacji mikroj\u0105der z wydajno\u015bci\u0105 j\u0105der monolitycznych. <\/p>\n

Komponenty j\u0105dra w Asterinas s\u0105 umieszczane w wsp\u00f3lnej przestrzeni adresowej, a bezpiecze\u0144stwo osi\u0105gane jest na poziomie logicznego podzia\u0142u bezpiecznego kodu i kodu, w kt\u00f3rym nie mo\u017cna wykluczy\u0107 pojawienia si\u0119 problem\u00f3w z bezpiecze\u0144stwem. J\u0105dro jest podzielone na dwie cz\u0119\u015bci, napisane w Rust: OS Framework i OS Services. W OS Services zabronione jest stosowanie blok\u00f3w unsafe, a wszystkie niskopoziomowe operacje wymagaj\u0105ce wykonania kodu w blokach unsafe zosta\u0142y przeniesione do OS Framework i s\u0105 dost\u0119pne tylko przez wysokopoziomowe API. Wszystkie wywo\u0142ania systemowe, systemy plik\u00f3w i sterowniki s\u0105 realizowane na poziomie OS Services i nie mog\u0105 zawiera\u0107 blok\u00f3w unsafe. <\/p>\n

Podczas tworzenia systemowych serwis\u00f3w i modu\u0142\u00f3w j\u0105dra zaleca si\u0119 korzystanie z narz\u0119dzi OSDK (Operating System Development Kit), kt\u00f3re oferuje narz\u0119dzie cargo-osdk do tworzenia, kompilowania, testowania i uruchamiania komponent\u00f3w systemu operacyjnego. Dla programist\u00f3w przygotowano zestaw bibliotek OSTD (Operating System Standard Library), stanowi\u0105cy redakcj\u0119 standardowych bibliotek Rust (crate std), dostosowan\u0105 do u\u017cycia w komponentach systemu operacyjnego.
