+Subject: [PATCH] sysdeps-unix: On MSG_CTRUNC, close the fds we did receive
+
+MSG_CTRUNC indicates that we have received fewer fds that we should
+have done because the buffer was too small, but we were treating it
+as though it indicated that we received *no* fds. If we received any,
+we still have to make sure we close them, otherwise they will be leaked.
+
+On the system bus, if an attacker can induce us to leak fds in this
+way, that's a local denial of service via resource exhaustion.
