From 1a2a4d06e1e95260c470ebe3a945f61bbe8c1fd8 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 21 Dec 2011 12:17:03 -0800 Subject: security: create task_free security callback The current LSM interface to cred_free is not sufficient for allowing an LSM to track the life and death of a task. This patch adds the task_free hook so that an LSM can clean up resources on task death.
