Projektet BSDun er offentliggjort, som udvikler et modul til Linux-kernen, der g\u00f8r det muligt at genkende, indl\u00e6se og k\u00f8re u\u00e6ndrede eksekverbare filer i ELF-format, som er samlet til FreeBSD. For at k\u00f8re anvendes et emuleret FreeBSD-milj\u00f8, der placeres i mappen \/compat\/freebsd. Generelt er projektet en fuldst\u00e6ndig mods\u00e6tning til FreeBSDs Linuxulator. Koden distribueres under GPLv2+ licensen og er skrevet ved hj\u00e6lp af AI-assistenten Claude Code. <\/p>\n

Med BSDun har det lykkedes at starte mange applikationer fra FreeBSD-pakker i Linux, herunder pkg, nginx, mc, ping, xeyes, xfce4-panel, Thunar, xfce4-terminal, Libreoffice, Midori, Epiphany, Chromium og VScode. For at starte Chromium og VScode kr\u00e6ves det, at sandbox-isoleringen deaktiveres, og st\u00f8rrelsen p\u00e5 videohukommelsen begr\u00e6nses ved hj\u00e6lp af indstillingerne «—no-sandbox —force-gpu-mem-available-mb=1024». <\/p>\n

Modulet har ikke til hensigt at blive en del af den prim\u00e6re kernel, da Linux-kernens arkitektur ikke tillader inclusion af andre executable file handlers (OS Personalities) siden fjernelsen af ABI Solaris, og kun \u00e9t system kaldetabel er forudset. For at omg\u00e5 dette problem er mekanismen kprobe blevet aktiveret i BSDun, som intercept\u00e9r alle system opkald. <\/p>\n

Ved hj\u00e6lp af kprobe blev FreeBSD-systemopkald adskilt fra Linux-systemopkald og pakket ind i en separat tabel. En del systemopkald fra FreeBSD blev direkte bundet til Linux-systemopkald, mens den anden del fik omarrangeret parameter- og resultatstrukturen, den tredje blev erstattet med store dele (f.eks. dem relateret til Capcicum), mens den fjerde blev implementeret baseret p\u00e5 de interne strukturer i Linux-kernen. For at implementere mekanismen kevent\/kqueue oven p\u00e5 epoll() blev der anvendt en modificering af komponenterne i brugerens rum, der automatisk udf\u00f8res ved indl\u00e6sning af hver FreeBSD-eksekverbar fil. <\/p>\n

I alt er der implementeret cirka 250 systemopkald. SystemV IPC, netv\u00e6rksfunktioner, futex'er, sysctl MIB, prctl, timere og ioctl er ogs\u00e5 implementeret. For at isolere filsystemer er der brugt chroot-milj\u00f8 p\u00e5 Linux-siden (i eksperimenternes forl\u00f8b skrev forfatteren indholdet i \\\/usr\\\/local\\\/* i Linux uden chroot ved at udf\u00f8re «pkg install …»). Alligevel kan nogle v\u00e6rkt\u00f8jer stadig fungere uden chroot. <\/p>\n

Det foresl\u00e5ede modul kan anvendes til udvikling, bygning og portering af software til FreeBSD uden anvendelse. virtual machines<\/a>.
