The grp stack is a data structure used by the kernel to keep track of a process's set of gids. Unlike the User ID (UID), which typically remains constant for a process throughout its lifetime, the gids can change dynamically as a process executes. This mechanism allows for flexible permission management, where processes can take on different levels of access based on their current effective or supplementary gids.
