| |
Hi everybody,
This is a beginning of work (started and suggested by Casey Schaufler) to let Audit be LSM neutral. This is done for proper audit<->SMACK integration which will also be useful for any future LSM.
What follows is four patches to remove the following exported SElinux interfaces: selinux_get_inode_sid(inode, sid) selinux_get_ipc_sid(ipcp, sid) selinux_get_task_sid(tsk, sid) selinux_sid_to_string(sid, ctx, len)
and substitue them respectively with: new LSM hook, inode_getsecid(inode, secid) new LSM hook, ipc_getsecid*(ipcp, secid) LSM hook, task_getsecid(tsk, secid) LSM hook, sid_to_secctx(sid, ctx, len)
The work isn't complete yet, and those four patches are sent for an early review. A new LSM interfaces/hooks will be created to substitute the SELinux exported audit interfaces, thus completing the separation.
It's worthy to note that those changes can be merged in their current state. The tree is fully grepped to make sure that no subsystem ,except the patched ones, will be affected by this SELinux API breakage.
