From 189b3b1c89761054fee3438f063d7f257306e2d8 Mon Sep 17 00:00:00 2001 From: "wzt.wzt@gmail.com" Date: Tue, 23 Feb 2010 23:15:28 +0800 Subject: Security: add static to security_ops and default_security_ops variable Enhance the security framework to support resetting the active security module. This eliminates the need for direct use of the security_ops and default_security_ops variables outside of security.c, so make security_ops and default_security_ops static. Also remove the secondary_ops variable as a cleanup since there is no use for that. secondary_ops was originally used by SELinux to call the "secondary" security module (capability or dummy), but that was replaced by direct calls to capability and the only remaining use is to save and restore the original security ops pointer value if SELinux is disabled by early userspace based on /etc/selinux/config. Further, if we support this directly in the security framework, then we can just use &default_security_ops for this purpose since that is now available.
