David Weston, vicepr\u00e6sident hos Microsoft, der er ansvarlig for sikkerheden af Windows-operativsystemet, delte i sin tale p\u00e5 BlueHat IL 2023-konferencen oplysninger om udviklingen af sikkerhedsmekanismerne i Windows. Blandt andet n\u00e6vnte han fremskridt i anvendelsen af Rust-sprog til at forbedre sikkerheden i Windows-kernen. Det blev endda oplyst, at Rust-koden muligvis vil blive tilf\u00f8jet til Windows 11-kernen allerede om et par m\u00e5neder eller endda uger. <\/p>\n

Blandt de prim\u00e6re motivationer for at anvende Rust n\u00e6vnes brugen af v\u00e6rkt\u00f8jer til sikker hukommelse og arbejdet med at reducere fejl i koden. Som et indledende m\u00e5l er det blevet meldt ud, at nogle interne C++ datatyper skal erstattes med de \u00e6kvivalente typer, der tilbydes af Rust. I dens nuv\u00e6rende form er omkring 36.000 linjer Rust-kode klar til at blive integreret i kernen. Testen af systemet med den nye kode viste, at der ikke var negativ indflydelse p\u00e5 ydeevnen i PCMark 10-pakken (kontorapplikationstest), og i nogle mikrotests viste den nye kode sig endda hurtigere.

\"Microsoft<\/center> <\/p>\n

Det f\u00f8rste omr\u00e5de, hvor Rust er blevet implementeret, er DWriteCore-koden, der sikrer parsing af skrifttyper. To udviklere er blevet involveret i projektet, som de har brugt et halvt \u00e5r p\u00e5 at omarbejde. Anvendelsen af den nyimplementerede Rust-version forbedrede ydeevnen ved glyph-generering af tekst med 5-15%. Det andet anvendelsesomr\u00e5de for Rust blev implementeringen af datatypen REGION i Win32k GDI (Graphics Driver Interface). De Rust-omskrevne GDI-komponenter har allerede best\u00e5et alle tests i Windows, og den nye kode planl\u00e6gges snart at blive inkluderet som standard i testversionerne af Windows 11 Insider. Andre pr\u00e6stationer relateret til Rust omfatter overs\u00e6ttelsen af bestemte systemopkald i Windows til dette sprog.
