102 | This option determines whether the new secmark-based network | ||
103 | controls will be enabled by default. If not, the old internal | ||
104 | per-packet controls will be enabled by default, preserving | ||
105 | old behavior. | ||
106 | |||
107 | If you enable the new controls, you will need updated | ||
108 | SELinux userspace libraries, tools and policy. Typically, | ||
109 | your distribution will provide these and enable the new controls | ||
110 | in the kernel they also distribute. | ||
111 | |||
112 | Note that this option can be overridden at boot with the | ||
113 | selinux_compat_net parameter, and after boot via | ||
114 | /selinux/compat_net. See Documentation/kernel-parameters.txt | ||
115 | for details on this parameter. | ||
116 | |||
117 | If you enable the new network controls, you will likely | ||
118 | also require the SECMARK and CONNSECMARK targets, as | ||
119 | well as any conntrack helpers for protocols which you | ||
120 | wish to control. | ||
