d381d8a9a0 [PATCH] SELinux: canonicalize getxattr()
This patch allows SELinux to canonicalize the value returned from
getxattr() via the security_inode_getsecurity() hook, which is called after
the fs level getxattr() function.

The purpose of this is to allow the in-core security context for an inode
to override the on-disk value.  This could happen in cases such as
upgrading a system to a different labeling form (e.g.  standard SELinux to
MLS) without needing to do a full relabel of the filesystem.

In such cases, we want getxattr() to return the canonical security context
that the kernel is using rather than what is stored on disk.

The implementation hooks into the inode_getsecurity(), adding another
parameter to indicate the result of the preceding fs-level getxattr() call,
so that SELinux knows whether to compare a value obtained from disk with
the kernel value.

We also now allow getxattr() to work for mountpoint labeled filesystems
(i.e.  mount with option context=foo_t), as we are able to return the
kernel value to the user.

Error reported: Variable "&((info)->tty)->flags" tracked as NULL was passed to a

a7dac447bb [libata] change ata_qc_complete() to take error mask as second arg
The second argument to ata_qc_complete() was being used for two
purposes: communicate the ATA Status register to the completion
function, and indicate an error.  On legacy PCI IDE hardware, the latter
is often implicit in the former.  On more modern hardware, the driver
often completely emulated a Status register value, passing ATA_ERR as an
indication that something went wrong.

Now that previous code changes have eliminated the need to use drv_stat
arg to communicate the ATA Status register value, we can convert it to a
mask of possible error classes.

This will lead to more flexible error handling in the future.

5fcbb23050 [PATCH] Remove policy contextualization from mbind
Policy contextualization is only useful for task based policies and not for
vma based policies.  It may be useful to define allowed nodes that are not
accessible from this thread because other threads may have access to these
nodes.  Without this patch strange memory policy situations may cause an
application to fail with out of memory.

Example:

Let's say we have two threads A and B that share the same address space and
a huge array computational array X.

Thread A is restricted by its cpuset to nodes 0 and 1 and thread B is
restricted by its cpuset to nodes 2 and 3.

Thread A now wants to restrict allocations to the first node and thus
applies a BIND policy on X to node 0 and 2.  The cpuset limits this to node
0.  Thus pages for X must be allocated on node 0 now.

Thread B now touches a page that has never been used in X and faults in a
page.  According to the BIND policy of the vma for X the page must be
allocated on page 0.  However, the cpuset of B does not allow allocation on
0 and 1.  Now the application fails in alloc_pages with out of memory.

208d54e551 [PATCH] memory hotplug locking: node_size_lock
pgdat->node_size_lock is basically only neeeded in one place in the normal
code: show_mem(), which is the arch-specific sysrq-m printing function.

Strictly speaking, the architectures not doing memory hotplug do no need this
locking in show_mem().  However, they are all included for completeness.  This
should also make any future consolidation of all of the implementations a
little more straightforward.

This lock is also held in the sparsemem code during a memory removal, as
sections are invalidated.  This is the place there pfn_valid() is made false
for a memory area that's being removed.  The lock is only required when doing
pfn_valid() operations on memory which the user does not already have a
reference on the page, such as in show_mem().

c6a57e19e4 [PATCH] memory hotplug prep: fixup bad_range()
When doing memory hotplug operations, the size of existing zones can obviously
change.  This means that zone->zone_{start_pfn,spanned_pages} can change.

There are currently no locks that protect these structure members.  However,
they are rarely accessed at runtime.  Outside of swsusp, the only place that I
can find is bad_range().

So, split bad_range() up into two pieces: one that needs to be locked and
anther that doesn't.
