From b889416b54c90f59276537debd92cb4e84b5f550 Mon Sep 17 00:00:00 2001 From: Balazs Scheidler Date: Sat, 23 Oct 2010 04:48:14 +0000 Subject: [PATCH] tproxy: Add missing CAP_NET_ADMIN check to ipv6 side IP_TRANSPARENT requires root (more precisely CAP_NET_ADMIN privielges) for IPV6. However as I see right now this check was missed from the IPv6 implementation. Acked-by: YOSHIFUJI Hideaki Signed-off-by: David S.
