From 6cc7a765c2987f03ba278dac03c7cc759ee198e7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Maciej=20=C5=BBenczykowski?= Date: Thu, 20 Oct 2011 18:21:36 -0400 Subject: net: allow CAP_NET_RAW to set socket options IP{,V6}_TRANSPARENT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Up till now the IP{,V6}_TRANSPARENT socket options (which actually set the same bit in the socket struct) have required CAP_NET_ADMIN privileges to set or clear the option. - we make clearing the bit not require any privileges. - we allow CAP_NET_ADMIN to set the bit (as before this change) - we allow CAP_NET_RAW to set this bit, because raw sockets already pretty much effectively allow you to emulate socket transparency.
