[CIFS] Fix incorrect mode when ACL had deny access control entries
When mounted with the cifsacl mount option, we were
treating any deny ACEs found like allow ACEs and it turns out for
SFU and SUA Windows set these type of access control entries often.
The order of ACEs is important too. The canonical order that most
ACL tools and Windows explorer consruct ACLs with is to begin with
DENY entries then follow with ALLOW, otherwise an allow entry
could be encountered first, making the subsequent deny entry like "dead
code which would be superflous since Windows stops when a match is
made for the operation you are trying to perform for your user
We start with no permissions in the mode and build up as we find
permissions (ie allow ACEs). This fixes deny ACEs so they affect
the mask used to set the subsequent allow ACEs.

[PATCH] audit: watching subtrees
New kind of audit rule predicates: "object is visible in given subtree".
The part that can be sanely implemented, that is. Limitations:
* if you have hardlink from outside of tree, you'd better watch
it too (or just watch the object itself, obviously)
* if you mount something under a watched tree, tell audit
that new chunk should be added to watched subtrees
* if you umount something in a watched tree and it's still mounted
elsewhere, you will get matches on events happening there. New command
tells audit to recalculate the trees, trimming such sources of false
positives.
Note that it's _not_ about path - if something mounted in several places
(multiple mount, bindings, different namespaces, etc.), the match does
_not_ depend on which one we are using for access.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:
"That Kconfig hasn't changed (other than adding new drivers), and it's
worked that way for several years now ... so the issue seems to be
changes in menuconfig/kconfig/etc semantics.
The issue is that when USB_GADGET=m, it's no longer possible to
configure peripheral controller drivers as modules ... the
controller drivers can now only be configured for static linkage.
It should be making a choice of one of the controller drivers which
could work on the target system, and allow that driver to be linked
either as a module (ok iff USB_GADGET=m) or statically."
Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

dm mpath: add retry pg init
This patch allows a failed path group initialisation command to be retried.
It adds a generic MP_RETRY flag and a "pg_init_retries" feature to
device-mapper multipath which limits the number of retries.
1. A hw handler sends a path initialization command to the storage and
the command completes with an error code indicating the command
should be retried.
2. The hardware handler calls dm_pg_init_complete() with MP_RETRY
set in err_flags to ask the dm multipath core to retry.
3. If the retry limit has not been exceeded, pg_init() is retried.
Otherwise fail_path() is called.
If you are using the userspace multipath-tools or device-mapper-multipath
package, you can set pg_init_retries in the 'device' section of your
/etc/multipath.conf file. For example:
features "2 pg_init_retries 7"
The number of PG retries attempted is reported in the 'dmsetup status' output.
