+android-cloexec-socket
+======================
+
+``socket()`` should include ``SOCK_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++
+
+  socket(domain, type, SOCK_STREAM);
+
+  // becomes
+
+  socket(domain, type, SOCK_STREAM | SOCK_CLOEXEC);
