Linus Torvalds angeschlossen<\/a><\/noindex> zur Diskussion die M\u00f6glichkeit<\/a><\/noindex> \u00fcber die Hinzuf\u00fcgung von Entwicklungswerkzeugen f\u00fcr die Programmiersprache Rust in den Linux-Kernel. Josh Triplett von Intel, der an dem Projekt<\/a><\/noindex> arbeitet, um Rust im Bereich der Systemprogrammierung auf Augenh\u00f6he mit C zu bringen, vorgeschlagen<\/a><\/noindex> Zu Beginn sollte in Kconfig eine Option zur Unterst\u00fctzung von Rust hinzugef\u00fcgt werden, die nicht dazu f\u00fchren w\u00fcrde, dass Rust-Compiler-Abh\u00e4ngigkeiten bei der Erstellung im Modus \u201emake allnoconfig\u201c und \u201emake allyesconfig\u201c ber\u00fccksichtigt werden, und die es erm\u00f6glichen w\u00fcrde, freier mit Rust-Code zu experimentieren. Ein \u00e4hnlicher Trick wurde bei Hinzuf\u00fcgung<\/a><\/noindex> der experimentellen Unterst\u00fctzung f\u00fcr die Clang-Builds im Optimierungsmodus w\u00e4hrend der Linkzeit (LTO, Link Time Optimization) umgesetzt, nach dem auch Support<\/a><\/noindex> Builds mit Schutz vor Befehlsflussverletzungen (CFI<\/a><\/noindex>, Control-Flow Integrity) hinzugef\u00fcgt werden sollen.<\/p>\n

Linus war anderer Meinung und \u00e4u\u00dferte Bedenken, dass die anf\u00e4ngliche Unterst\u00fctzung von Rust ungetestet bleiben k\u00f6nnte und das Risiko besteht, in einem Sumpf zu versinken, in dem eine kleine Gruppe von Entwicklern, die an dem Projekt interessiert sind, den Code nur unter ihren spezifischen Bedingungen \u00fcberpr\u00fcft und falsche Elemente hinzuf\u00fcgt, da diese verborgen bleiben und bei Tests des Kernels in anderen Umgebungen nicht ans Licht kommen. <\/p>\n

Laut Linus sollte der erste Rust-Treiber in einem einfachen Format angeboten werden, in dem Fehler offensichtlich und leicht zu erkennen sind. Um das Testen zu vereinfachen, empfahl er, es so zu handhaben wie bei der \u00dcberpr\u00fcfung von C-Compiler-Versionen und unterst\u00fctzten Flags \u2013 n\u00e4mlich zu \u00fcberpr\u00fcfen, ob ein Rust-Compiler im System installiert ist, und dessen Unterst\u00fctzung zu aktivieren, wenn dies der Fall ist. <\/p>\n
