Describe the feature you would like

To be able to get unix socket file path (sun_path), we need to add support for the sockaddr_un struct.

Recently, tetragon received support for the struct sockaddr in https://github.com/cilium/tetragon/pull/3358, but to fully support UNIX sockets, we also need to support the sockaddr_un structure.

That will allow us to develop policies to detect and filter operations on specific UNIX sockets such as docker.sock and containerd.sock by hooking into functions such as unix_stream_connect() .

Describe your proposed solution
