2018-02-09	apparmor: move context.h to cred.h	John Johansen
	Now that file contexts have been moved into file, and task context fns() and data have been split from the context, only the cred context remains in context.h so rename to cred.h to better reflect what it deals with. Signed-off-by: John Johansen <john.johansen@canonical.com>

2018-02-09	apparmor: drop cred_ctx and reference the label directly	John Johansen
	With the task domain change information now stored in the task->security context, the cred->security context only stores the label. We can get rid of the cred_ctx and directly reference the label, removing a layer of indirection, and unneeded extra allocations. Signed-off-by: John Johansen <john.johansen@canonical.com>
2018-02-09	apparmor: move task domain change info to task security	John Johansen
	The task domain change info is task specific and its and abuse of the cred to store the information in there. Now that a task->security field exists store it in the proper place. Signed-off-by: John Johansen <john.johansen@canonical.com>

2017-06-10	apparmor: switch from profiles to using labels on contexts	John Johansen
	Begin the actual switch to using domain labels by storing them on the context and converting the label to a singular profile where possible. Signed-off-by: John Johansen <john.johansen@canonical.com>
2017-06-10	apparmor: convert to profile block critical sections	John Johansen
	There are still a few places where profile replacement fails to update and a stale profile is used for mediation. Fix this by moving to accessing the current label through a critical section that will always ensure mediation is using the current label regardless of whether the tasks cred has been updated or not.

2017-01-16	apparmor: add ns being viewed as a param to policy_view_capable()	John Johansen
	Prepare for a tighter pairing of user namespaces and apparmor policy namespaces, by making the ns to be viewed available and checking that the user namespace level is the same as the policy ns level. This strict pairing will be relaxed once true support of user namespaces lands. Signed-off-by: John Johansen <john.johansen@canonical.com>
2017-01-16	apparmor: rename PFLAG_INVALID to PFLAG_STALE	John Johansen
	Invalid does not convey the meaning of the flag anymore so rename it. Signed-off-by: John Johansen <john.johansen@canonical.com>
2013-08-14	apparmor: change how profile replacement update is done	John Johansen
	remove the use of replaced by chaining and move to profile invalidation and lookup to handle task replacement. Replacement chaining can result in large chains of profiles being pinned in memory when one profile in the chain is use. With implicit labeling this will be even more of a problem, so move to a direct lookup method. Signed-off-by: John Johansen <john.johansen@canonical.com>

2010-08-02	AppArmor: contexts used in attaching policy to system objects	John Johansen
	AppArmor contexts attach profiles and state to tasks, files, etc. when a direct profile reference is not sufficient. Signed-off-by: John Johansen <john.johansen@canonical.com> Signed-off-by: James Morris <jmorris@namei.org>
