Foi publicado o projeto BSDun, que desenvolve um m\u00f3dulo para o n\u00facleo Linux que permite reconhecer, carregar e executar arquivos execut\u00e1veis no formato ELF, compilados para FreeBSD, de forma n\u00e3o modificada no Linux. Para a execu\u00e7\u00e3o, um ambiente emulado do FreeBSD \u00e9 utilizado, localizado no diret\u00f3rio \/compat\/freebsd. De forma geral, o projeto \u00e9 exatamente o oposto do Linuxulator do FreeBSD. O c\u00f3digo \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv2+ e foi escrito com a ajuda do assistente AI Claude Code. <\/p>\n

Com a ajuda do BSDun, foi poss\u00edvel executar com sucesso no Linux muitos aplicativos dos pacotes FreeBSD, entre os quais pkg, nginx, mc, ping, xeyes, xfce4-panel, Thunar, xfce4-terminal, Libreoffice, Midori, Epiphany, Chromium e VScode. Para executar o Chromium e o VScode, \u00e9 necess\u00e1rio desativar a prote\u00e7\u00e3o sandbox e limitar o tamanho da mem\u00f3ria de v\u00eddeo usando as op\u00e7\u00f5es «—no-sandbox —force-gpu-mem-available-mb=1024». <\/p>\n

O m\u00f3dulo n\u00e3o pretende ser inclu\u00eddo na composi\u00e7\u00e3o principal do n\u00facleo, pois desde a remo\u00e7\u00e3o da ABI Solaris, a arquitetura do n\u00facleo Linux n\u00e3o permite a inclus\u00e3o de outros manipuladores de arquivos execut\u00e1veis (OS Personalities) e prev\u00ea apenas uma tabela de chamadas de sistema. Para contornar esse problema, o BSDun utilizou o mecanismo kprobe, que intercepta todas as chamadas de sistema. <\/p>\n

Com o kprobe, as chamadas de sistema do FreeBSD eram separadas das chamadas de sistema do Linux e encapsuladas em uma tabela separada. Parte das chamadas de sistema do FreeBSD estava diretamente vinculada \u00e0s chamadas de sistema do Linux, enquanto para outras, a estrutura de par\u00e2metros e resultados era reempacotada, algumas eram substitu\u00eddas por stubs (por exemplo, relacionadas ao Capcicum), e outras eram implementadas com base nas estruturas internas do n\u00facleo Linux. Para implementar o mecanismo kevent\/kqueue sobre epoll(), uma modifica\u00e7\u00e3o separada dos componentes no espa\u00e7o do usu\u00e1rio foi aplicada, realizada automaticamente ao carregar cada arquivo execut\u00e1vel do FreeBSD. <\/p>\n

No total, foram implementadas cerca de 250 chamadas de sistema. Tamb\u00e9m foram implementados IPC do SystemV, fun\u00e7\u00f5es de rede, futexes, MIB sysctl, prctl, temporizadores e ioctl. Para delimitar sistemas de arquivos, foi utilizado um ambiente chroot no lado do Linux (durante os testes, sem chroot, o autor executou «pkg install …» e regravou o conte\u00fado de \\\/usr\\\/local\\\/* no Linux). No entanto, algumas utilidades ainda podem funcionar sem chroot. <\/p>\n

O m\u00f3dulo proposto pode ser utilizado para o desenvolvimento, compila\u00e7\u00e3o e portabilidade de software para FreeBSD sem necessidade de utiliza\u00e7\u00e3o. m\u00e1quinas virtuais<\/a>.
