历史

项目历史与用法

libcap-ng is Steve Grubb's Linux capability library and utility suite, designed to make POSIX capability programming easier than the older libcap API.

项目历史

The libcap-ng site states the design goal directly: make programming with POSIX capabilities easier than the traditional libcap library. 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.

采用历史

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.

使用方式

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.

为什么软件包爱好者会关心

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.

时间线

  • 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.
