The VMX implementation of enable_irq_window raised
KVM_REQ_IMMEDIATE_EXIT after we checked it in vcpu_enter_guest. This
caused infinite loops on vmentry. Fix it by letting enable_irq_window
signal the need for an immediate exit via its return value and drop
KVM_REQ_IMMEDIATE_EXIT.
This issue only affects nested VMX scenarios.

currently apparmor name parsing is only correctly handling
:<NS>:<profile>
but
:<NS>://<profile>
is also a valid form and what is exported to userspace.

Also cleanup setprocattr some more while we are at it.

smatch reports
error: potential NULL dereference 'ns'.
this can not actually occur because it relies on aa_split_fqname setting
both ns_name and name as null but ns_name will actually always have a
value in this case.
so remove the unnecessary if (ns_name) conditional that is resulting
in the false positive further down.

The top 8 bits of the base field have never been used, in fact can't
be used, by the current 'dfa16' format. However they will be used in the
future as flags, so mask them off when using base as an index value.
Note: the use of the top 8 bits, without masking is trapped by the verify
checks that base entries are within the size bounds.

Move the free_profile fn ahead of aa_alloc_profile so it can be used
in aa_alloc_profile without a forward declaration.

The sid is not going to be a direct property of a profile anymore, instead
it will be directly related to the label, and the profile will pickup
a label back reference.
For null-profiles replace the use of sid with a per namespace unique
id.

Instead of limiting the setting of the processes limits to current,
relax this to tasks confined by the same profile, as the apparmor
controls for rlimits are at a profile level granularity.

-ESTALE used to be incorrectly used to indicate a disconnected path, when

-EACCESS, but the error to failure message mapping was not correctly updated
to reflect this change.

When policy specifies a transition to a profile that is not currently
loaded, it result in exec being denied. However the failure is not being
audited correctly because the audit code is treating this as an allowed
permission and thus not reporting it.

This is primarily useful when there's a driver that doesn't claim clocks
properly, but the bootloader leaves them on. It's not expected to be used
in normal cases, but for bringup and debug it's very useful to have the
option to not gate unclaimed clocks that are still on.
