 Revision history for Perl extension IO::FDPass
 
+        - hardening: limit cmsg->cmsg_len to controllen, as some buggy OSes
+          allow buffer overruns otherwise.
+        - hardening: do not leak fds on fdpass protocol failures.
+        - hardening: close extra fd's sent by non-compliant sender.
