From 041dc07fd21b6987ffbcc6a597eb9918d44ae841 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Tue, 6 Dec 2011 15:57:15 -0800 Subject: [PATCH] socket-util: Don't try to listen to a UDP socket. The "listen" system call doesn't work and isn't necessary for UDP, but inet_open_passive() would still try to call it (and fail). This doesn't fix a real bug because the two existing callers both use inet_open_passive() to listen for TCP connections.
