+=============================
+
+``inotify_init1()`` should include ``IN_CLOEXEC`` in its type argument to avoid the
+file descriptor leakage. Without this flag, an opened sensitive file would
+remain open across a fork+exec to a lower-privileged SELinux domain.
+
+Examples:
+
+.. code-block:: c++
+
+  inotify_init1(IN_NONBLOCK);
+
+  // becomes
+
+  inotify_init1(IN_NONBLOCK | IN_CLOEXEC);
