Subject: [PATCH try #3] 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.
Signed-off-by: James Morris <jmorris@...ei.org>
---
I've just resynced this patch to the current Linus git and tested various
permutations of configuration options. The only real change to the code
is to account for the extra mmap hook arguments.
Please review and consider for 2.6.23 merge.
