From d720024e94de4e8b7f10ee83c532926f3ad5d708 Mon Sep 17 00:00:00 2001 From: Michael LeMay Date: Thu, 22 Jun 2006 14:47:17 -0700 Subject: [PATCH] selinux: add hooks for key subsystem Introduce SELinux hooks to support the access key retention subsystem within the kernel. Incorporate new flask headers from a modified version of the SELinux reference policy, with support for the new security class representing retained keys. Extend the "key_alloc" security hook with a task parameter representing the intended ownership context for the key being allocated. Attach security information to root's default keyrings within the SELinux initialization routine. Has passed David's testsuite.
