+From: Leonardo Chiquitto <leonardo@ngdn.org>
+Subject: Check for signals in update_kernel_random()
+
+When running as a daemon, a signal handler is installed to catch
+SIGINT/SIGTERM. This handler sets a flag that's tested in the main
+loop. However, rngd loops in update_kernel_random() as well, where
+the flag was not tested.
+
+This patch adds the check to update_kernel_random() so that the
+daemon exits properly after receiving a SIGINT/SIGTERM signal.
