From 4a19ec5800fc3bb64e2d87c4d9fdd9e636086fe0 Mon Sep 17 00:00:00 2001 From: Laszlo Attila Toth Date: Wed, 30 Jan 2008 19:08:16 -0800 Subject: [NET]: Introducing socket mark socket option. A userspace program may wish to set the mark for each packets its send without using the netfilter MARK target. Changing the mark can be used for mark based routing without netfilter or for packet filtering. It requires CAP_NET_ADMIN capability.
