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