Its README demonstrates common use cases such as dropping all capabilities, keeping selected capabilities, checking capability state, and retaining capabilities across UID changes. The project paired the C library with administrative tools. netcap reports listening network processes and their capabilities, pscap reports privileged processes, filecap searches for files with file capabilities, and cap-audit can audit capability checks when built with the optional eBPF-based tooling. ### Adoptionsgeschichte libcap-ng was adopted by Linux distributions because it gives application developers and packagers a smaller API for privilege dropping, while giving administrators tools to inspect capability exposure across a running system. ### Wie es verwendet wird Developers use capng_clear, capng_update, capng_apply, and related calls to drop or retain Linux capabilities. Administrators use pscap, netcap, and filecap to find over-privileged processes and files. ### Warum Paket-Nerds sich dafür interessieren In package-manager terms, libcap-ng is a security plumbing package: it is rarely user-facing, but it makes least-privilege patches shorter and more reviewable. That is exactly the kind of small library that changes whether downstream packages actually drop privileges. ### Zeitleiste - 0.4: Initial public release, according to the upstream ChangeLog. - 0.6: Added Python bindings and an m4 macro for autotools consumers. - 0.8: Added ambient capability support and V3 filesystem capability support. - 2024-04-09: The project site listed libcap-ng 0.8.5 release files. - 0.9: The README documents a distribution move away from people.redhat.com release hosting to the GitHub page. ### Related projects - Related projects include libcap, Linux capabilities, file capabilities, procfs capability inspection, systemd ambient capabilities, and eBPF-based capability auditing. ### Quellen - - - - - ## Sicherheitshinweise library-like package without higher-risk signals. -
