Miguel Ojeda, autor do projeto Rust-for-Linux, prop\u00f4s \u00e0 considera\u00e7\u00e3o dos desenvolvedores do n\u00facleo Linux o lan\u00e7amento da vers\u00e3o v10 dos componentes para desenvolvimento de drivers de dispositivos na linguagem Rust. Esta \u00e9 a d\u00e9cima primeira edi\u00e7\u00e3o dos patches, levando em conta a primeira vers\u00e3o, publicada sem n\u00famero de vers\u00e3o. A inclus\u00e3o do suporte a Rust foi aprovada por Linus Torvalds para ser incorporada ao n\u00facleo Linux 6.1, a menos que surjam problemas inesperados. O desenvolvimento \u00e9 financiado pela Google e pela organiza\u00e7\u00e3o ISRG (Internet Security Research Group), que \u00e9 a fundadora do projeto Let's Encrypt e contribui para a promo\u00e7\u00e3o do HTTPS e o desenvolvimento de tecnologias para melhorar a seguran\u00e7a na internet. <\/p>\n

Assim como a vers\u00e3o anterior dos patches, a vers\u00e3o v10 foi reduzida ao m\u00ednimo necess\u00e1rio para compilar um simples m\u00f3dulo do n\u00facleo escrito na linguagem Rust. As diferen\u00e7as em rela\u00e7\u00e3o \u00e0 vers\u00e3o anterior se resumem a pequenas corre\u00e7\u00f5es, substitui\u00e7\u00e3o de sizeof por ARRAY_SIZE no kallsyms.c e adapta\u00e7\u00e3o dos patches ao n\u00facleo v6.0-rc7. A expectativa \u00e9 que o patch m\u00ednimo, cuja extens\u00e3o foi reduzida de 40 para 13 mil linhas de c\u00f3digo, facilite a aceita\u00e7\u00e3o do suporte para Rust no n\u00facleo principal. Ap\u00f3s garantir um suporte m\u00ednimo, a inten\u00e7\u00e3o \u00e9 aumentar gradualmente a funcionalidade existente, transferindo outras altera\u00e7\u00f5es da branch Rust-for-Linux. <\/p>\n

As mudan\u00e7as propostas permitem o uso do Rust como uma segunda linguagem para o desenvolvimento de drivers e m\u00f3dulos do n\u00facleo. O suporte ao Rust \u00e9 apresentado como uma op\u00e7\u00e3o, n\u00e3o ativada por padr\u00e3o e que n\u00e3o resulta na inclus\u00e3o do Rust como uma depend\u00eancia de compila\u00e7\u00e3o obrigat\u00f3ria para o n\u00facleo. O uso do Rust para desenvolver drivers permitir\u00e1 a cria\u00e7\u00e3o de drivers seguros e de qualidade superior com o m\u00ednimo de esfor\u00e7o, eliminando problemas como acesso a \u00e1reas de mem\u00f3ria ap\u00f3s a libera\u00e7\u00e3o, desreferencia\u00e7\u00e3o de ponteiros nulos e estouro de buffer. <\/p>\n

A seguran\u00e7a no manuseio da mem\u00f3ria \u00e9 garantida no Rust durante a compila\u00e7\u00e3o atrav\u00e9s da verifica\u00e7\u00e3o de refer\u00eancias, rastreamento da propriedade dos objetos e considera\u00e7\u00e3o do tempo de vida dos objetos (escopo), bem como pela avalia\u00e7\u00e3o da corre\u00e7\u00e3o do acesso \u00e0 mem\u00f3ria durante a execu\u00e7\u00e3o do c\u00f3digo. O Rust tamb\u00e9m oferece ferramentas para prote\u00e7\u00e3o contra estouros inteiros, exige a inicializa\u00e7\u00e3o obrigat\u00f3ria dos valores das vari\u00e1veis antes do uso, lida melhor com erros na biblioteca padr\u00e3o, aplica o conceito de imutabilidade (immutable) para refer\u00eancias e vari\u00e1veis por padr\u00e3o e oferece forte tipagem est\u00e1tica para minimizar erros l\u00f3gicos.
