<h2>
<i>seitan</i> is a framework to filter, transform and impersonate system calls,
enabling privilege reduction in container and virtualisation engines
</h2>
It allows you to filter and replay only the system calls you need, instead of
running things as root, or granting capabilities to processes.
<ul>
<li><pre style="display: inline">seitan-cooker</pre> builds a BPF program and a
bytecode file (<i>gluten</i>) from a recipe with matches on system calls and
corresponding actions</li>
<li><pre style="display: inline">seitan-eater</pre> loads the BPF program
associated to the process context into the kernel, and runs the target
process. Container engines such as Podman can directly load this program via
OCI annotations instead</li>
<li><pre style="display: inline">seitan</pre> is the supervisor, getting
notifications via <pre style="display: inline">seccomp_unotify</pre>,
interpreting them according to <i>gluten</i>, and triggering the configured
actions as a result</li>
</ul>
<h5>Note that this project and its documentation still have some rough edges! No versions, no packages yet.</h5>
