[PATCH v15 00/22] Richacls (Core and Ext4)

From: Andreas Gruenbacher
Date: Mon Nov 09 2015 - 06:09:23 EST


Here is another update to the richacl patch queue. This posting contains
the patches ready to be merged; the patches later in the queue still need
some more review.

Changes since the last posting (http://thread.gmane.org/gmane.linux.kernel.cifs/11221):

* Replacing an existing file or directory requires to be able to delete
and recreate it. A new function may_replace was added to test for replace
access vs. delete access (may_delete); this simplifies the code and makes it
more readable. Without richacls, deleting and creating requires the same
permissions, and making that distinction wasn't useful.

* The DELETE permission on a file was accidentally allowing to replace the
file without also requiring the ADD_FILE permission on the containing
directory. This was fixed and a regression test was added to the test
suite.

* A comment as to how pages for XDR-encoded ACLs are alocated was added to
__nfs4_proc_set_acl. (See the complete patch queue for that.)
