Jean Tourrilhes 711e2c33ac [PATCH] WE-20 for kernel 2.6.16
This is version 20 of the Wireless Extensions. This is the
completion of the RtNetlink work I started early 2004, it enables the
full Wireless Extension API over RtNetlink.

	Few comments on the patch :
	o totally driver transparent, no change in drivers needed.
	o iwevent were already RtNetlink based since they were created
(around 2.5.7). This adds all the regular SET and GET requests over
RtNetlink, using the exact same mechanism and data format as iwevents.
	o This is a Kconfig option, as currently most people have no
need for it. Surprisingly, patch is actually small and well
encapsulated.
	o Tested on SMP, attention as been paid to make it 64 bits clean.
	o Code do probably too many checks and could be further
optimised, but better safe than sorry.
	o RtNetlink based version of the Wireless Tools available on
my web page for people inclined to try out this stuff.

	I would also like to thank Alexey Kuznetsov for his helpful
suggestions to make this patch better.

Version 2 of the patch. Added checks for version 0

mode we won't receive packets from another BSSes.

bcm43xx_rx() contains code to filter out packets from

James Morris 7cae7e26f2 [PATCH] SELinux: add slab cache for inode security struct
Add a slab cache for the SELinux inode security struct, one of which is
allocated for every inode instantiated by the system.

The memory savings are considerable.

On 64-bit, instead of the size-128 cache, we have a slab object of 96
bytes, saving 32 bytes per object.  After booting, I see about 4000 of
these and then about 17,000 after a kernel compile.  With this patch, we
save around 530KB of kernel memory in the latter case.  On 32-bit, the
savings are about half of this.

Stephen Smalley 8aad38752e [PATCH] selinux: Disable automatic labeling of new inodes when no policy is loaded
This patch disables the automatic labeling of new inodes on disk
when no policy is loaded.

Discussion is here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180296

In short, we're changing the behavior so that when no policy is loaded,
SELinux does not label files at all.  Currently it does add an 'unlabeled'
label in this case, which we've found causes problems later.

SELinux always maintains a safe internal label if there is none, so with this
patch, we just stick with that and wait until a policy is loaded before adding
a persistent label on disk.

The effect is simply that if you boot with SELinux enabled but no policy
loaded and create a file in that state, SELinux won't try to set a security
extended attribute on the new inode on the disk.  This is the only sane
behavior for SELinux in that state, as it cannot determine the right label to
assign in the absence of a policy.  That state usually doesn't occur, but the
rawhide installer seemed to be misbehaving temporarily so it happened to show
up on a test install.

The list_lock also protects the shared array and we call drain_array() with

take the lock in a way so that it also protects the array_cache in
drain_pages.

(Note: maybe we should make the array_cache locking more consistent?  I.e.
always take the array cache lock for shared arrays and disable interrupts
for the per cpu arrays?)

Christoph Lameter aab2207cf8 [PATCH] slab: make drain_array more universal by adding more parameters
And a parameter to drain_array to control the freeing of all objects and
then use drain_array() to replace instances of drain_array_locked with
drain_array.  Doing so will avoid taking locks in those locations if the
arrays are empty.
