 8          SafeSetID is an LSM module that gates the setid family of syscalls to
 9          restrict UID/GID transitions from a given UID/GID to only those
10          approved by a system-wide whitelist. These restrictions also prohibit
11          the given UIDs/GIDs from obtaining auxiliary privileges associated
12          with CAP_SET{U/G}ID, such as allowing a user to set up user namespace
13          UID mappings.
