priv_sep

priv_sep is a library for privilege separation. It is currently designed around pledge(2) and unveil(2) for OpenBSD, but in the future may contain functionality for Linux's seccomp(2).

Pledge

Calls to pledge(2) are done via Promises::pledge and pledge_none.

Note that since the use of execpromises is quite rare, NULL is always used for it.

Unveil

Calls to unveil(2) are done via Permissions::unveil and unveil_no_more.

Errors

Any error returned from the underlying system call is propagated via Error.

Status

This package will be actively maintained to stay in-sync with the latest version of OpenBSD; as a result, the crate is only tested on the x86_64-unknown-openbsd target. While OpenBSD supports both the most recent -release/-stable release as well as the previous version, only the most recent version will be supported by this library. If using -stable, it may be necessary to build the rust port from -current.
