Mastering POSIX File Capabilities

Posted by kdawson on from the wee-dram-of-privilege dept.

An anonymous reader passes along an IBM DeveloperWorks article on POSIX file capabilities, which have recently become available in the Linux kernel; they are expected in the mainline kernel by 2.6.24. POSIX file capabilities parcel out root user powers into smaller privileges. The article details how to program using file capabilities and how to switch on the ability of a system's setuid root binaries to use file capabilities.
