From b5a4fb1c95fd2738259456a6e1fd140db3698a21 Mon Sep 17 00:00:00 2001 From: Steven Barth Date: Sat, 16 Nov 2013 09:18:14 +0000 Subject: 6rd: Clear correct IPv6 address bits in 6rdcalc The correct bits are now cleared in the IPv6 address as the shift value to the correct byte in the IPv6 address was wrong. Depending on the stack values this could result in a hanging 6rdcalc program due to an endless loop.
