From 6f5317e730505d5cbc851c435a2dfe3d5a21d343 Mon Sep 17 00:00:00 2001 From: Harry Ciao Date: Wed, 2 Mar 2011 13:32:33 +0800 Subject: SELinux: Socket retains creator role and MLS attribute The socket SID would be computed on creation and no longer inherit its creator's SID by default. Socket may have a different type but needs to retain the creator's role and MLS attribute in order not to break labeled networking and network access control. The kernel value for a class would be used to determine if the class if one of socket classes. If security_compute_sid is called from userspace the policy value for a class would be mapped to the relevant kernel value first.
