From b9fb15067ce93497bef852c05e406d7a96212a9a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?T=C3=B3th=20L=C3=A1szl=C3=B3=20Attila?= Date: Wed, 1 Oct 2008 07:31:24 -0700 Subject: [PATCH] ipv4: Allow binding to non-local addresses if IP_TRANSPARENT is set MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Setting IP_TRANSPARENT is not really useful without allowing non-local binds for the socket. To make user-space code simpler we allow these binds even if IP_TRANSPARENT is set but IP_FREEBIND is not. Signed-off-by: Tóth László Attila Signed-off-by: David S.
