历史

项目历史与用法

libcap is Andrew G. Morgan's user-space library and utility suite for Linux capabilities, including setcap, getcap, getpcaps, capsh, pam_cap, and related support libraries.

项目历史

The upstream README describes libcap as a library for getting and setting POSIX.1e draft 15 capabilities, with native C/C++ and Go support. The Fully Capable site frames Linux capabilities as an alternative to the superuser model of privilege under Linux and notes that the Linux implementation is based on the defunct POSIX.1e draft.

The project grew beyond a C library into a family of privilege-management tools and helper code. The README names capsh, getpcaps, setcap, and getcap as example programs, while the Fully Capable site documents libpsx for POSIX semantics in threaded applications and Go packages for capability manipulation.

采用历史

libcap became baseline Linux security infrastructure because file capabilities and process capabilities need user-space tooling. Distribution packages expose its command-line tools for administrators and its headers and library for software that must drop root while keeping only specific privileges.

使用方式

Administrators use setcap and getcap to assign and inspect file capabilities, getpcaps to inspect processes, and capsh to experiment with capability sets and shells. Developers link libcap when applications need direct control over Linux capability state.

为什么软件包爱好者会关心

libcap is one of the packages that turns a kernel security feature into everyday packaging policy. Without it, downstream maintainers have a harder time replacing setuid-root patterns with smaller capability grants.
