\u00c8 stato pubblicato il progetto BSDun, che sviluppa un modulo per il kernel Linux, consentendo di riconoscere, caricare ed eseguire in Linux file eseguibili non modificati nel formato ELF, compilati per FreeBSD. Per l'esecuzione viene utilizzato un ambiente emulato FreeBSD, collocato nella directory \/compat\/freebsd. In generale, il progetto \u00e8 l'opposto completo del Linuxulator di FreeBSD. Il codice \u00e8 distribuito con licenza GPLv2+ ed \u00e8 stato scritto utilizzando l'assistente AI Claude Code. <\/p>\n
Con BSDun, \u00e8 stato possibile avviare con successo molte applicazioni Linux dai pacchetti FreeBSD, tra cui pkg, nginx, mc, ping, xeyes, xfce4-panel, Thunar, xfce4-terminal, Libreoffice, Midori, Epiphany, Chromium e VScode. Per avviare Chromium e VScode \u00e8 necessario disabilitare l'isolamento sandbox e limitare la dimensione della memoria video utilizzando le opzioni \u00ab--no-sandbox --force-gpu-mem-available-mb=1024\u00bb. <\/p>\n
Il modulo non mira a essere incluso nel core del kernel, poich\u00e9 a partire dall'eliminazione dell'ABI Solaris, l'architettura del kernel Linux non consente l'inclusione di altri gestori di file eseguibili (OS Personalities) e prevede solo una tabella delle chiamate di sistema. Per aggirare questo problema, in BSDun \u00e8 stato impiegato il meccanismo kprobe, che intercetta tutte le chiamate di sistema. <\/p>\n
Attraverso kprobe, le chiamate di sistema FreeBSD sono state separate dalle chiamate di sistema Linux e incapsulate in una tabella separata. Una parte delle chiamate di sistema FreeBSD \u00e8 stata direttamente collegata alle chiamate di sistema Linux, per un'altra \u00e8 stata effettuata la riimpacchettazione della struttura dei parametri e del risultato, una terza \u00e8 stata sostituita con delle stub (ad esempio, quelle relative a Capcicum), e una quarta \u00e8 stata realizzata sulla base delle strutture interne del kernel Linux. Per implementare il meccanismo kevent\/kqueue sopra epoll(), \u00e8 stata utilizzata una modifica separata dei componenti nello spazio utente, eseguita automaticamente al caricamento di ogni file eseguibile FreeBSD. <\/p>\n
In totale sono stati implementati circa 250 chiamate di sistema. Sono stati implementati anche SystemV IPC, funzioni di rete, futex, sysctl MIB, prctl, timer e ioctl. Per isolare i file system \u00e8 stato utilizzato un ambiente chroot lato Linux (durante gli esperimenti, senza chroot, l'autore eseguendo \u00abpkg install ...\u00bb ha sovrascritto il contenuto di \/usr\/local\/* in Linux). Tuttavia, alcune utility possono ancora funzionare senza chroot. <\/p>\n
Il modulo proposto pu\u00f2 essere utilizzato per lo sviluppo, la compilazione e il porting di software per FreeBSD senza utilizzo. macchine virtuali<\/a>.
