This patch introduce domain transition mechanism into Smack. The idea was to give a process limited ability to change its Smack label without giving that process CAP_MAC_ADMIN capabilities. Moreover, this ability is granted without any additional Smack policy rules.
This feature consists of two, new kernel interfaces: - <smack_fs>/relabel-possible - for setting transition privilege - <smack_fs>/relabel-list - for transition-labels list Process can set transition flag only to itself and only if has CAP_MAC_ADMIN capability. Process can transit (only once) into other Smack label only if it has transition flag set 'on' and target domain is on relabel-list. Changes in v2: * squashed into one commit Zbigniew Jasinski (1): Introducing domain transition mechanism into Smack.
