LSM: do not initialize common_audit_data to 0

2012-04-09T16:23:04Z

It isn't needed. If you don't set the type of the data associated with that type it is a pretty obvious programming bug. So why waste the cycles? Signed-off-by: Eric Paris

apparmor: move task from common_audit_data to apparmor_audit_data

2012-04-09T16:23:02Z

apparmor is the only LSM that uses the common_audit_data tsk field. Instead of making all LSMs pay for the stack space move the aa usage into the apparmor_audit_data. Signed-off-by: Eric Paris

LSM: remove the COMMON_AUDIT_DATA_INIT type expansion

2012-04-09T16:23:01Z

Just open code it so grep on the source code works better. Signed-off-by: Eric Paris

LSM: shrink sizeof LSM specific portion of common_audit_data

2012-04-03T16:48:40Z

Linus found that the gigantic size of the common audit data caused a big perf hit on something as simple as running stat() in a loop. This patch requires LSMs to declare the LSM specific portion separately rather than doing it in a union. Thus each LSM can be responsible for shrinking their portion and don't have to pay a penalty just because other LSMs have a bigger space requirement.

AppArmor: mediation of non file objects

2010-08-02T05:38:35Z

ipc: AppArmor ipc is currently limited to mediation done by file mediation and basic ptrace tests. Improved mediation is a wip. rlimits: AppArmor provides basic abilities to set and control rlimits at a per profile level. Only resources specified in a profile are controled or set. AppArmor rules set the hard limit to a value <= to the current hard limit (ie. they can not currently raise hard limits), and if necessary will lower the soft limit to the new hard limit value. AppArmor does not track resource limits to reset them when a profile is left so that children processes inherit the limits set by the parent even if they are not confined by the same profile. Capabilities: AppArmor provides a per profile mask of capabilities, that will further restrict. Signed-off-by: John Johansen Signed-off-by: James Morris
