Subject[PATCH v28 00/21] Richacls (Core and Ext4)
Date
Here is another update of the richacl patches.  Changes since the last posting
(https://lwn.net/Articles/703199/):

* Fix permission checking for file exchange (i.e., renameat2 with the
RENAME_EXCHANGE flag): in some cases, the MAY_CREATE_FILE and MAY_CREATE_DIR
permissions were swapped.

This should have been caught by the test suite but wasn't. Meanwhile the
test suite is fixed as well.

* When deleting a file and we have MAY_DELETE_SELF permission on the file, we
don't require MAY_DELETE_CHILD permission on the containing directory.
However, we must still call inode_permission with MAY_WRITE in mask for
checks beyond file permission bits or ACLs, such as LSM.


Many thanks to Miklos for the previous patch review.
