prosody-openbsd: pledge and unveil sandboxing

description

prosody-openbsd is an OpenBSD sandboxing module for Prosody, using pledge(2) and unveil(2) to minimize process capabilities and filesystem visibility.

The default set of pledge promises and configuration-derived unveil paths should suffice for typical Prosody installations from OpenBSD ports. Bindings to ktrace(2) are included to assist with determining additional promises and paths to supplement the defaults.

todo

Finer-grained /var/prosody permissions by default.
