[PATCH v2 0/1] Introducing domain transition mechanism into Smack

Show all headers | View raw

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.
