Implementations

impl UserNamespaceMapper

pub fn new(config: UserNamespaceConfig) -> Self

pub fn setup_mappings(&self) -> Result<()>

Setup UID/GID mappings for the current process

This must be called after unshare(CLONE_NEWUSER) and before any other namespace operations

pub fn write_mappings_for_pid(&self, pid: u32) -> Result<()>

Write UID/GID mappings for the given process from an external writer.

For privileged multi-ID mappings, Linux requires a task outside the new user namespace to write /proc/<pid>/{uid,gid}_map.

pub fn config(&self) -> &UserNamespaceConfig

Get the user namespace configuration
