From 20510f2f4e2dabb0ff6c13901807627ec9452f98 Mon Sep 17 00:00:00 2001 From: James Morris Date: Tue, 16 Oct 2007 23:31:32 -0700 Subject: security: Convert LSM into a static interface Convert LSM into a static interface, as the ability to unload a security module is not required by in-tree users and potentially complicates the overall security architecture. Needlessly exported LSM symbols have been unexported, to help reduce API abuse. Parameters for the capability and root_plug modules are now specified at boot. The SECURITY_FRAMEWORK_VERSION macro has also been removed. In a nutshell, there is no safe way to unload an LSM. The modular interface is thus unecessary and broken infrastructure. It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux.
