From bbdb32cb5b73597386913d052165423b9d736145 Mon Sep 17 00:00:00 2001 From: Benjamin LaHaise Date: Tue, 20 Mar 2012 03:57:54 +0000 Subject: Fix pppol2tp getsockname() While testing L2TP functionality, I came across a bug in getsockname(). The IP address returned within the pppol2tp_addr's addr memember was not being set to the IP address in use. This bug is caused by using inet_sk() on the wrong socket (the L2TP socket rather than the underlying UDP socket), and was likely introduced during the addition of L2TPv3 support.
