Un grup de dezvoltatori din China lucreaz\u0103 la nucleul Asterinas, scris \u00een limbajul Rust \u0219i destinat utiliz\u0103rii \u00een sisteme de operare de uz general. Pentru a facilita integrarea cu componentele sistemului deja dezvoltate, nucleul ofer\u0103 un ABI (Interfa\u021ba Binara de Aplica\u021bie) compatibil cu nucleul Linux \u0219i care poate fi folosit ca alternativ\u0103. Codul proiectului este distribuit sub licen\u021ba MPL (Mozilla Public License). <\/p>\n

Proiectul a evoluat din toamna anului 2022 \u0219i inten\u021bioneaz\u0103 s\u0103 ating\u0103 \u00een acest an un nivel adecvat pentru utilizare pe scar\u0103 larg\u0103 \u00een virtu\u00e1lne ma\u0161ini<\/a> cu arhitectura x86-64. \u00cencep\u00e2nd de anul viitor, aten\u021bia principal\u0103 se va concentra asupra implement\u0103rii suportului hardware \u0219i altor arhitecturi CPU. Printre domeniile prioritize men\u021bionate se num\u0103r\u0103 sistemele legate de ABI Linux, dar care necesit\u0103 un nivel mai ridicat de securitate. De exemplu, Asterinas este sugerat pentru a fi utilizat \u00een formarea unui mediu sistemic securizat ma\u0219ini virtuale<\/a>, pentru care se folosesc tehnologii precum ARM CCA, AMD SEV \u0219i Intel TDX, precum \u0219i de partea sistemului gazd\u0103, care asigur\u0103 rularea containerelor. <\/p>\n

Pentru a reduce probabilitatea apari\u021biei de erori \u00een gestionarea memoriei, o surs\u0103 principal\u0103 a celor mai periculoase vulnerabilit\u0103\u021bi, la scrierea Asterinas s-a folosit limbajul Rust \u0219i o tactic\u0103 de utilizare limitat\u0103 a blocurilor unsafe. Nucleul este construit folosind arhitectura framekernel, \u00een care dezvoltatorii au \u00eencercat s\u0103 combine capacit\u0103\u021bile de izolare ale microkernel-urilor cu eficien\u021ba kernel-urilor monolitice. <\/p>\n

Componentele nucleului \u00een Asterinas sunt plasate \u00een acela\u0219i spa\u021biu de adrese, iar securitatea este realizat\u0103 la nivelul separ\u0103rii logice \u00eentre codul sigur \u0219i codul \u00een care nu se exclud problemele de securitate. Nucleul este \u00eemp\u0103r\u021bit \u00een dou\u0103 p\u0103r\u021bi, scrise \u00een Rust: OS Framework \u0219i OS Services. \u00cen OS Services utilizarea blocurilor unsafe este interzis\u0103, iar toate opera\u021biunile de nivel inferior, care necesit\u0103 executarea codului \u00een blocuri unsafe, sunt externalizate \u00een OS Framework \u0219i accesibile doar printr-o API de nivel \u00eenalt. Toate apelurile de sistem, sistemele de fi\u0219iere \u0219i driverele sunt realizate la nivelul OS Services \u0219i nu pot include blocuri unsafe. <\/p>\n

\u00cen dezvoltarea serviciilor sistemice \u0219i a modulelor de nucleu, se recomand\u0103 utilizarea instrumentului OSDK (Operating System Development Kit), care ofer\u0103 utilitarul cargo-osdk pentru crearea, compilarea, testarea \u0219i rularea componentelor sistemului de operare. Pentru dezvoltatori, a fost preg\u0103tit un set de biblioteci OSTD (Operating System Standard Library), care reprezint\u0103 o revizuire a bibliotecilor standard Rust (crate std), adaptat\u0103 pentru utilizarea \u00een componentele sistemului de operare.
