From 47670b767b1593433b516df7798df03f858278be Mon Sep 17 00:00:00 2001 From: Julian Anastasov Date: Sun, 7 Aug 2011 09:16:09 +0000 Subject: ipv4: route non-local sources for raw socket The raw sockets can provide source address for routing but their privileges are not considered. We can provide non-local source address, make sure the FLOWI_FLAG_ANYSRC flag is set if socket has privileges for this, i.e. based on hdrincl (IP_HDRINCL) and transparent flags.
