Un groupe de d\u00e9veloppeurs en Chine d\u00e9veloppe le noyau Asterinas, \u00e9crit en langage Rust et destin\u00e9 \u00e0 \u00eatre utilis\u00e9 dans des syst\u00e8mes d'exploitation \u00e0 usage g\u00e9n\u00e9ral. Pour faciliter l'int\u00e9gration avec les composants syst\u00e8me d\u00e9j\u00e0 d\u00e9velopp\u00e9s, le noyau fournit une ABI (Application Binary Interface), compatible avec le noyau Linux et pouvant \u00eatre utilis\u00e9 en son remplacement. Le code du projet est distribu\u00e9 sous la licence MPL (Mozilla Public License). <\/p>\n

Le projet est en cours de d\u00e9veloppement depuis l'automne 2022 et pr\u00e9voit d\u00e9j\u00e0 cette ann\u00e9e d'atteindre un niveau adapt\u00e9 \u00e0 une large utilisation dans des machines virtuelles<\/a> l'architecture x86-64. \u00c0 partir de l'ann\u00e9e prochaine, l'accent sera principalement mis sur la mise en \u0153uvre du support mat\u00e9riel et d'autres architectures de CPU. Parmi les domaines d'application prioritaires figurent les syst\u00e8mes bas\u00e9s sur l'ABI Linux, mais n\u00e9cessitant un niveau de s\u00e9curit\u00e9 plus \u00e9lev\u00e9. Par exemple, Asterinas est propos\u00e9 pour la cr\u00e9ation d'environnements syst\u00e8me s\u00e9curis\u00e9s machines virtuelles<\/a>, pour lesquels des technologies telles que ARM CCA, AMD SEV et Intel TDX sont utilis\u00e9es, ainsi que du c\u00f4t\u00e9 du syst\u00e8me h\u00f4te, garantissant l'ex\u00e9cution des conteneurs. <\/p>\n

Pour r\u00e9duire la probabilit\u00e9 d'erreurs lors de l'utilisation de la m\u00e9moire, qui constituent la principale source des vuln\u00e9rabilit\u00e9s les plus dangereuses, le langage Rust et une strat\u00e9gie d'utilisation limit\u00e9e des blocs unsafe ont \u00e9t\u00e9 employ\u00e9s dans l'\u00e9criture d'Asterinas. Le noyau est construit en utilisant une architecture framekernel, o\u00f9 les d\u00e9veloppeurs ont tent\u00e9 de combiner les capacit\u00e9s d'isolation des micro-noyaux avec l'efficacit\u00e9 des noyaux monolithiques. <\/p>\n

Les composants du noyau dans Asterinas sont dispos\u00e9s dans un espace d'adressage commun, et la s\u00e9curit\u00e9 est atteinte au niveau de la s\u00e9paration logique du code s\u00e9curis\u00e9 et du code o\u00f9 il peut y avoir des probl\u00e8mes de s\u00e9curit\u00e9. Le noyau est divis\u00e9 en deux parties, \u00e9crites en Rust : OS Framework et OS Services. L'utilisation de blocs unsafe est interdite dans OS Services, et toutes les op\u00e9rations \u00e0 bas niveau requ\u00e9rant l'ex\u00e9cution de code dans des blocs unsafe ont \u00e9t\u00e9 transf\u00e9r\u00e9es vers OS Framework et ne sont accessibles que via une API de haut niveau. Tous les appels syst\u00e8me, syst\u00e8mes de fichiers et pilotes sont mis en \u0153uvre au niveau d'OS Services et ne peuvent pas inclure des blocs unsafe. <\/p>\n

Lors du d\u00e9veloppement de services syst\u00e8me et de modules de noyau, il est recommand\u00e9 d'utiliser l'outil OSDK (Operating System Development Kit), qui fournit l'utilitaire cargo-osdk pour cr\u00e9er, assembler, tester et ex\u00e9cuter les composants du syst\u00e8me d'exploitation. Un ensemble de biblioth\u00e8ques OSTD (Operating System Standard Library) a \u00e9t\u00e9 pr\u00e9par\u00e9 pour les d\u00e9veloppeurs, repr\u00e9sentant une version des biblioth\u00e8ques standard Rust (crate std), adapt\u00e9e \u00e0 l'utilisation dans les composants du syst\u00e8me d'exploitation.
