From f0e3d0689da401f7d1981c2777a714ba295ea5ff Mon Sep 17 00:00:00 2001 From: Mike Waychison Date: Wed, 10 Aug 2011 21:59:57 -0700 Subject: tcp: initialize variable ecn_ok in syncookies path Using a gcc 4.4.3, warnings are emitted for a possibly uninitialized use of ecn_ok. This can happen if cookie_check_timestamp() returns due to not having seen a timestamp. Defaulting to ecn off seems like a reasonable thing to do in this case, so initialized ecn_ok to false.
