commit 8d096a0572b955835f7f64f267a29047091e0a8e Author: Olaf Kirch <okir@suse.de> Date: Wed Nov 12 16:10:53 2008 +0100 Fix a bug in clnt broadcast Before calling the replyproc function on a broadcast reply, we convert the server-provided address using uaddr2taddr. This may fail (eg if the server provided a garbage address), and return NULL. In this case, we should not call the replyproc function - because the caller expects the address netbuf to be a valid pointer, rather than NULL.
