- IP_NF_CONNTRACK_MARK is bool and depends on only IP_NF_CONNTRACK
  which is tristate. If a variable depends on IP_NF_CONNTRACK_MARK and
  doesn't care about IP_NF_CONNTRACK, it can be y. This must be avoided.
- IP_NF_CT_ACCT has same problem.
- IP_NF_TARGET_CLUSTERIP also depends on IP_NF_MANGLE.

addrconf_verify(...) only traverse address hash table when
addrconf_hash_lock is held for writing, and it may hold
addrconf_hash_lock for a long time. So I think it's better to acquire
addrconf_hash_lock for reading instead of writing

From http://bugzilla.kernel.org/show_bug.cgi?id=4746

There is user data corruption when using ioctl(SIOCGIFCONF) in 32-bit
application running amd64 kernel. I do not think that this problem is
exploitable, but any data corruption may lead to security problems.
Following code demonstrates the problem

#include <stdint.h>
#include <stdio.h>
#include <sys/time.h>
#include <sys/socket.h>
#include <net/if.h>
#include <sys/ioctl.h>

char buf[256];

main()
{
	int s = socket(AF_INET, SOCK_DGRAM, 0);
	struct ifconf req;
	int i;

	req.ifc_buf = buf;
	req.ifc_len = 41;

	printf("Result %d\n", ioctl(s, SIOCGIFCONF, &req));
	printf("Len %d\n", req.ifc_len);
	for (i = 41; i < 256; i++)
		if (buf[i] != 0)
			printf("Byte %d is corrupted\n", i);
}
	
Steps to reproduce:
Compile the code above into 32-bit elf and run it. You'll get
Result 0
Len 32
Byte 48 is corrupted
Byte 52 is corrupted
Byte 53 is corrupted
Byte 54 is corrupted
Byte 55 is corrupted

If two packets were queued to be sent at the same time in the future,
their order would be reversed.  This would occur because the queue is
traversed back to front, and a position is found by checking whether
the new packet needs to be sent before the packet being examined.  If
the new packet is to be sent at the same time of a previous packet, it
would end up before the old packet in the queue.  This patch places
packets in the correct order when they are queued to be sent at a same
time in the future.

If thread that submitted FF request gets interrupted somehow it
will release request structure and ioctl handler will work with
freed memory. TO prevent that from happening switch to using
wait_for_completion instead of wait_for_completion_interruptible.

Also fix a potential issue with some notebooks:

The current code assumes the response to bios_wifi_get_default_setting is
either 1 (disabled) or 3 (enabled), or wifi isn't supported.  The BIOS
response appears to be a bit field w/ 0x1 indicating hardware presence, 0x2
indicating actiation status, and the other 6 bits being unknown/reserved --
with the patch, these 6 bits are ignored.

A driver for laptop buttons using an x86 BIOS interface that is
apparently used on quite a few laptops and seems to be originating
from Wistron.

This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000
(i.e. it can detect the laptop using DMI and it contains the
keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G
(probably can't be reliably autodetected, requires a module parameter),
adding other laptops should be easy.

In addition to reporting button presses to the input layer the driver
also allows enabling/disabling the embedded wireless NIC (using the
"Wifi" button); this is done using the same BIOS interface, so it seems
only logical to keep the implementation together.  Any flexibility
possibly gained by allowing users to remap the function of the "Wifi"
button is IMHO not worth it when weighted against the necessity to run
an user-space daemon to convert button presses to wifi state changes.

Changing led state is pretty slow operation; when there are multiple
requests coming at a high rate they may interfere with normal typing.
Try optimize (skip) changing hardware state when multiple requests
are coming back-to-back.
