   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.
