The rsuid LSM software is a module for Linux that enables users with particular UID to move to all other users within specific ranges. It facilitates switching within the kernel.
RSUID LSM is a remarkable kernel module designed for Linux operating systems. With this software, a user that possesses unique UID can quickly shift to all users within a particular range.
RSUID LSM provides a new way to make set*uid() and set*gid() calls by altering the way certain processes operate. The restriction is rather stringent as it applies to a process as well as all its child processes. It is pertinent to mention that a root process can only enable the limitations, and once enabled, the restrictions can't be reversed.
To enable the RSUID LSM, the root must set uid_min and gid_min before the software can be turned on successfully. The enable_rsuid script offers an example of how the software module should be enabled. A process can trigger the restrictions by writing 'rsuid enable' into /proc/< pid >/attr/exec. Once activated, the process necessarily forfeits all its existing capabilities before switching to the new uid/gid.
The installation process for RSUID LSM is straightforward. First, the user simply has to run "make," then "make install" once the compilation is successful. Overall, the RSUID LSM remains a unique and valuable software module for all Linux users, providing greater user control and security, and making it a must-have for those seeking smart and effective security solutions.
