Functions

func Read

func Read(iter *link.Iter) ([]byte, error)

Read reads the iterator in the host pid namespace. It will test if the current pid namespace is the host pid namespace.

func ReadOnCurrentPidNs

func ReadOnCurrentPidNs(iter *link.Iter) ([]byte, error)

ReadOnCurrentPidNs reads the iterator in the current pid namespace.

func ReadOnHostPidNs

func ReadOnHostPidNs(iter *link.Iter) ([]byte, error)

ReadOnHostPidNs reads the iterator in the host pid namespace. It does so by pinning the iterator in a temporary directory in the host bpffs, and then creating a systemd service that will read the iterator and write it to a temporary pipe. The pipe is then read and returned.
