Subject: [PATCH 3/6] NetLabel: change the SELinux permissions
Date: Thu, 21 Sep 2006 12:57:06 -0400 [thread overview]
Message-ID: <20060921170336.334044000@hp.com> (raw)
In-Reply-To: 20060921165703.251871000@hp.com
[-- Attachment #1: netlabel-selinux_perm --]
[-- Type: text/plain, Size: 1365 bytes --]
Change NetLabel to use the 'recvfrom' socket permission and the
SECINITSID_NETMSG SELinux SID as the NetLabel base SID for incoming packets.
This patch effectively makes the old, and currently unused, SELinux NETMSG
permissions NetLabel permissions.
