inode_setattr hook

2

 

==================

3

 

 

4

 

* Reiserfs uses private directories and files for storing xattrs.

5

 

  It should set ATTR_FORCE when changing attributes on these

6

 

  files and directories with notify_change(). This may save us

7

 

  from constructing temporary struct path objects there.

8

 

 

9

 

* AppArmor should check for ATTR_FORCE in its inode_setattr hook,

10

 

  and should not log or deny ATTR_FORCE setattrs. SELinux does

11

 

  that already as well. (For private inodes, the security_*

12

 

  functions already skip the lsm hooks though, so this may be

13

 

  unnecessary.)
