Sandboxing

FreeBSD

On FreeBSD, Vgmi uses capsicum(4) to limit the filesystem and to enter capability mode, it also uses cap_net(3) for networking while in capability mode.

OpenBSD

On OpenBSD, Vgmi uses unveil(2) to limit access to the filesystem and pledge(2) to restrict the capabilities of the program.

Linux

On Linux, Vgmi uses seccomp(2) to restrict system calls and landlock(7) to restrict the filesystem.

Illumos and Solaris

On Illumos and Solaris, Vgmi uses privileges(7) to isolate the parser processes.

On top of sandboxing the main process, Vgmi forks itself to parse foreign data

in completely isolated and sandboxed processes.

LibreSSL - fork of OpenSSL developed by the OpenBSD project

termbox2 - terminal rendering library

Optional dependency
